Background
Atrial fibrillation is one of the most common clinical arrhythmia, the stroke result caused by atrial fibrillation is very serious, and the death rate and disability rate can reach 70%. For patients with valvular atrial fibrillation, 57% of atrial thrombi originate in the left atrial appendage, and for patients with non-valvular atrial fibrillation, 90% of left atrial thrombi originate in the left atrial appendage. Even after sinus rhythm is restored, contraction of the left atrial appendage is arrested and thrombus may form.
At present, three methods for clinically preventing atrial fibrillation and ischemic stroke are provided. One method is to take anticoagulant drugs such as warfarin, but warfarin has certain bleeding risk, needs frequent monitoring, has more contraindications and is difficult to apply clinically; warfarin also has the potential to cause osteoporosis and soft tissue necrosis. The second method is to directly excise or ligate the atrial appendage at the same time as the cardiac surgery, and the main disadvantage of this method is that the complete closure rate of the left atrial appendage is low, and previous studies show that the success rate of completely excising the left atrial appendage is about 80% at the highest. The third method is to close the left auricle by an auricle clamp type instrument and perform left auricle occlusion operation in a percutaneous interventional endocardium, but the conveyor of the product has complex operation, high risk and yet to be verified in safety and effectiveness.
The auricle clamp that current auricle clamp conveyor carried generally includes two parallel arm lock, still has two spring parts simultaneously, and these two spring parts are located the both ends of auricle clamp, can keep the clamp of two arm lock through these two spring parts. The front end of the auricle clamp conveying device is generally provided with a slightly square outer frame so as to bind the auricle clamp in the auricle clamp conveying device, the conveying device outer frame utilizes a traction rope to pull a clamping arm of the auricle clamp so as to tension the traction rope, and therefore the auricle clamp can be pulled open, and the auricle clamp can be driven to clamp and convey to a focus to execute the extracardiac closing operation of the left auricle.
The problem that above-mentioned current auricle clamp conveyor exists is, for the auricle clamp that the adaptation has two parallel arm lock, its frame needs parallel motion to two arm lock of control auricle clamp are keeping parallelism in the tight in-process of clamp continuously, just so lead to auricle clamp conveyor's frame great, make the degree of difficulty of sending into great, and need great operating space in focus department, and this also makes the big and risk of closed operation degree of difficulty higher.

The third connecting end C includes the connecting ends of the third link 303 and the fourth link 304 with the swing seat 20, i.e., the second end 303b of the third link 303 and the second end 304b of the fourth link 304, and further includes the first end 307a and the second end 307b of the seventh link 307.
With the link mechanism 30 in this embodiment, when the control mechanism applies a pulling force from the rear side of the control end D to the control end D toward the rear side of the conveying actuator, since the second end 303b of the third link 303 and the second end 304b of the fourth link 304 are hinged to the swing seat 20, and the positions thereof are fixed, in the four-link structure formed by four connecting ends, i.e., the second end 301b of the first link 301 (the first end 304a of the fourth link 304), the second end 302b of the second link 302 (the first end 303a of the third link 303), the second end 303b of the third link 303 (the second end 304b of the second link 304), and the hinged ends of the first link 301 and the second link 302, the second end 301b of the first link 301 (the first end 304a of the fourth link 304) and the second end 302b of the second link 302 (the first end 303a of the third link 303) move away from each other, and the hinged ends of the first link 301 and the second link 302 move toward each other in the direction in which the second end 303b of the third link 303 (the second end 304 b) moves toward each other. Accordingly, the first end 301a of the first link 301 and the first end 302a of the second link 302 are opposite each other, i.e., at the first front connection end A1, the first jawarm 40 is biased in a direction away from the second jawarm 50 and tends to move away from the second jawarm 50, and at the second front connection end B1, the second jawarm 50 is biased in a direction away from the first jawarm 40 and tends to move away from the first jawarm 40.
A parallelogram four-bar linkage structure is formed between the first end 301a of the first link 301, the first end 305a of the fifth link 305, the first end 307a of the seventh link 307 (the hinged ends of the fifth link 305 and the sixth link 306), and the second end 307b of the seventh link 307 (the hinged ends of the first link 301 and the second link 302). Under the condition that the seventh link 307 is located in the guide slot 201 of the swing seat 20 and is constrained to move only along the guide slot 201 toward the rear end of the conveying actuator, the first link 301 drives the first clamp arm 40 to move toward the second clamp arm 50 at the first end 301a, i.e., the first front connection end A1, and during the moving process, the four-link structure maintains the parallelogram shape, so that at the first rear connection end A2, the first clamp arm 40 also moves toward the second clamp arm 50, and the parallel state between the first clamp arm 40 and the seventh link 307 is maintained.
Similarly, a parallelogram four-link structure is also formed between the first end 302a of the second link 302, the first end 306a of the sixth link 306, the first end 307a of the seventh link 307 (the hinged ends of the fifth link 305 and the sixth link 306), and the second end 307b of the seventh link 307 (the hinged ends of the first link 301 and the second link 302). The second link 302 drives the second clamp arm 50 to move back to the first clamp arm 40 at the first end 302a, i.e., the second front connection end B1, and during the movement, the four-link structure maintains the parallelogram shape, so that the second clamp arm 50 also moves back to the first clamp arm 40 at the second rear connection end B2, and the parallel state between the second clamp arm 50 and the seventh link 307 is maintained.
Thus, as described above, the control mechanism applies a rearward pulling force to the control end D, so that the first and second arms 40 and 50 are moved away from each other in parallel to change the state to the opened state.
Conversely, when the control mechanism no longer applies a pulling force to the control end D from the rear side of the control end D, the control mechanism releases the control end D, and at this time, the implant connected and fixed to the first and second forceps arms 40 and 50 of the delivery actuator can apply opposite forces to the first and second forceps arms 40 and 50 (for example, specifically, by providing an elastic component in a stretching state on the implant), under which forces the first and second forceps arms 40 and 50 tend to approach each other and transition to the closed state. The process of shifting to the closed state is similar to the process of shifting the first and second clamp arms 40 and 50 to the open state, and the process will not be described again, and the final state is achieved by moving the seventh link 307 to the initial position in the front direction along the guide groove 201 on the swing seat 20.
With the seventh link 307, the second end of the first link 307 is actually the hinged end of the first link 301 and the second link 302, and the first end of the first link 307 is actually the hinged end of the fifth link 305 and the sixth link 306, as shown in fig. 14 and in conjunction with fig. 7, in other embodiments of the delivery actuator, the hinged end of the fifth link 305 and the second link 306 can also be the control end D, which is equivalent to the above-mentioned embodiment with the hinged end of the first link 301 and the second link 302 as the control end D.
In the present embodiment, the swing seat 20 rotates in a plane relative to the base 10, rather than freely swinging in three-dimensional space, so that fewer control components are required for the swing seat 20 to control its rotation relative to the base 10, thereby reducing the equipment cost; meanwhile, the swing seat 20 has fewer control nodes rotating relative to the base 10, so that the probability of failure in the control process can be reduced, and the reliability of motion control can be improved.
In addition, the link mechanism 30 in the embodiment has a simple structure and a small volume, and can reduce the operation difficulty when the first forceps arm 40 and the second forceps arm 50 are moved close to or away from each other in parallel without requiring a large operation space.
Referring to fig. 1 to 4, the first and second jawarms 40 and 50 are coplanar with each other with respect to a plane in which the swing base 20 moves and a plane of rotation in which the swing base 20 rotates with respect to the base 10; in other words, the two planes are substantially a plane, and the rotation of the first and second clamp arms 40 and 50 relative to the swing base 20 and the rotation of the swing base 20 relative to the base 10 are motions in the same plane.
In this embodiment, the plane in which the first and second clamp arms 40 and 50 are relatively moved with respect to the swing base 20 and the plane in which the swing base 20 is rotated with respect to the base 10 are the same plane, so that it is convenient to move the implant to the target position in one plane, and to close or open the first and second clamp arms 40 and 50 in the same plane at the target position. In general, the direction in which the implant moves at the target position is determined, and based on the determined moving direction, since the rotating direction of the swing base 20 relative to the base 10 and the determined moving direction have a relationship, the determined moving direction can be used as a reference when the swing base 20 is controlled to rotate relative to the base 10, so that the rotation of the swing base 20 relative to the base 10 can be accurately controlled, and the first and second clamp arms 40 and 50 and the implant fixed thereto can be accurately moved to the target position.
In the present embodiment, as shown in fig. 9, the first caliper arm 40 is provided with a first linear tying portion 401, and the opening of the first linear tying portion 401 is directed toward the second caliper arm 50. The first linear binding portion 401 may be used to bind a clip arm of the implant M such as an auricle clip, and the clip arm of the implant M may be fixed in the first linear binding portion 401 by using a wire satisfying a certain requirement between the first linear binding portion 401 and the clip arm of the implant M. The second jawarm 50 is provided with a second linear binding portion 501, and the opening of the second linear binding portion 501 faces the first jawarm 40. The second linear binding portion 501 may be used to bind a clip arm of the implant M such as an auricle clip, and the clip arm of the implant M may be fixed in the second linear binding portion 501 by using a wire conforming to a certain requirement between the second linear binding portion 501 and the clip arm of the implant M.
The first linear locking portion 401 and the second linear locking portion 501 are used to connect the implant M, thereby fixing the implant M to the transfer actuator. Taking the implant M as an auricle clamp as an example, the first linear binding portion 401 and the second linear binding portion 501 are respectively connected with two clamping arms of the auricle clamp, so as to fix the auricle clamp on the conveying actuator; after the auricle clamp is fixed on the conveying actuator, the opening and closing of the first clamp arm 40 and the second clamp arm 50 can drive the two clamp arms of the auricle clamp to approach or depart from each other in parallel, and the left auricle clamp can be clamped and closed along with the parallel approaching of the first clamp arm 40 and the second clamp arm 50 at the target position.
The shapes of the first linear binding portion 401 and the second linear binding portion 501 may be linear grooves corresponding to the shapes of the arms of the implant M, the arms and the linear grooves of the implant M may be connected and fixed together by using the corresponding relationship in the shapes, and the first linear binding portion 401 and the second linear binding portion 501 may also be non-groove structures, such as a planar structure, in which the arms of the implant M are bound and fixed by lines.
Specifically, the first caliper arm 40 is provided with a first fixing groove 402 that contacts the first linear tying part 401. The first fixing groove 402 is used to insert a connecting wire and fix the inserted object to the first linear binding portion 401. The second caliper arm 50 is provided with a second fixing groove 502 connected to the second linear locking portion 501. The second fixing groove 502 is also used for inserting a connecting wire to fix the implant to the second linear fixing portion 501.
The number of the first fixing grooves 402 is at least two, and the number of the second fixing grooves 502 is at least two. This arrangement makes it possible to bind and fix the implant to the first linear binding portion 401 at least at two positions and to bind and fix the implant to the second linear binding portion 501 at least two positions, thereby making it possible to more firmly bind and fix the implant to the first linear binding portion 401 and the second linear binding portion 501 in the longitudinal direction of the first and second forceps arms 40 and 50.
The first jaw arm 40 is provided with a first notch 403, and the first notch 403 is disposed at the tail end of the first jaw arm 40. The second jawarm 50 is provided with a second notch 503, and the second notch 503 is provided at the rear end of the second jawarm 50. First and second notches 403 and 503 are configured to receive projections of an implant toward first and second jawarms 40 and 50. Taking the auricle clamp as an example, the elastic connecting portion connected between the two arms of the auricle clamp will protrude toward the first and second arms 40 and 50 at the connecting portion with the two arms, and the first and second notches 403 and 503 can accommodate the elastic connecting portion, so as to prevent interference between the auricle clamp and the first and second arms 40 and 50.
In addition, the present invention may be implemented by simply changing the above-described embodiments as alternative embodiments. In an alternative embodiment, as shown in FIGS. 10-13, the plane in which the first and second jawarms 40, 50 move relative to the swing base 20 and the plane of rotation of the swing base 20 relative to the base 10 are perpendicular to each other, rather than in a coplanar relationship as in embodiment 1 above. However, the same as the above embodiment 1, the number of control parts required for controlling the swing seat 20 to rotate relative to the base 10 is small, the number of control nodes for controlling the swing seat 20 to rotate relative to the base 10 is small, and the link mechanism 30 has a simple structure and a small volume, and does not require a large operation space when the first and second clamp arms 40 and 50 are moved close to or away from each other in parallel, so that the difficulty of operation can be reduced when the implant is to be transported. Similarly to the above embodiment 1, a relation is also established between the rotation direction of the swing seat 20 with respect to the base 10 and the determined direction in which the implant moves at the target position, and based on the relation, when the swing seat 20 is controlled to rotate with respect to the base 10, the rotation of the swing seat 20 with respect to the base 10 can be accurately controlled with reference to the determined movement direction, thereby facilitating accurate movement of the first and second clamp arms 40 and 50 and the implant fixed thereto to the target position.
In another alternative embodiment of the present invention, the first and second clamp arms 40 and 50 may be constructed as shown in fig. 16 to 17 and 21 to 23, for example. In the structure shown in fig. 16 to 17 and 21 to 23, the first and second forceps arms 40 and 50 are also provided with a first linear binding portion 401 and a second linear binding portion 501 for receiving the implant M, and a slot for fixing the implant M.
In another alternative embodiment of the present invention, the link mechanism 30 may be different from the link mechanism in the above-described embodiment, as shown in fig. 16 to 19, and in this alternative embodiment, the link mechanism 30 includes a first link 301, a second link 302, a third link 303, a fourth link 304, a fifth link 305, and a sixth link 306. The first link 301 and the second link 302 are hinged, and the hinged ends of the first link 301 and the second link 302 are located between the first end 301a and the second end 301b of the first link 301 and between the first end 302a and the second end 302b of the second link 302, so that the first link 301 and the second link 302 form an X-shaped scissors structure; the hinge axes of the first link 301 and the second link 302 are hinged to the swing seat 20. First ends 301a, 302a of the first and second links 301, 302 are hingedly connected to the first and second jawarms 40, 50, respectively, and second ends 301b, 302b of the first and second links 301, 302 are hingedly connected to first ends 303a, 304a of the third and fourth links 303, 304, respectively; the second ends 303b, 304b of the third link 303 and the fourth link 304 are hinged. First ends 305a and 306a of the fifth link 305 and the sixth link 306 are respectively hinged with the first jawarm 40 and the second jawarm 50, second ends 305b and 306b of the fifth link 305 and the sixth link 306 are hinged, and a hinged shaft of the fifth link 305 and the sixth link 306 is hinged with the swinging seat 20. The swing seat 20 is provided with a guide groove 201, and the direction of the guide groove 201 is parallel to the first tong arm 40 and the second tong arm 50; the hinge shafts of the third link 303 and the fourth link 304 are disposed in the guide groove 201 and can slide along the guide groove 201. The hinged ends of the third connecting rod 303 and the fourth connecting rod 304 are control ends D; the hinged end of the first connecting rod 301 and the first forceps arm 40 is a first front connecting end A1, and the hinged end of the fifth connecting rod 305 and the first forceps arm 40 is a first rear connecting end A2; the hinged end of the second connecting rod 302 and the second forceps arm 50 is a second front connecting end B1, and the hinged end of the sixth connecting rod 306 and the second forceps arm 50 is a second rear connecting end B2.
In this alternative embodiment, the first and second clamp arms 40 and 50 are controlled to open by applying a force to the control end D in a forward direction (which force, when applied, can be achieved by a wire isoline structure; specifically, the wire isoline structure can be led out from the handheld operation portion at the rear end, wound around the hinge axes of the first and second links 301 and 302, or the hinge axes of the fifth and sixth links 305 and 306, and folded back to the control end D for connection and fixation, so that the wire isoline structure is pulled back at the handheld operation portion to act on the control end D as a forward acting force); by releasing this tension on control end D, first and second jawarms 40, 50 are clamped. Specifically, when a pulling force toward the front side is applied to the control end D, that is, the hinged ends of the third link 303 and the fourth link 304, the hinged ends of the first link 301 and the fourth link 304, and the hinged ends of the second link 302 and the third link 303 are driven to move forward and open outward first; further acting on the hinged end (first front connecting end A1) of the first connecting rod 301 and the first forceps arm 40 and the hinged end (second front connecting end B1) of the second connecting rod 302 and the second forceps arm 50 to open the two outwards; and, the fifth link 305 and the hinged end (first rear connecting end A2) of the first forceps arm 40 and the hinged end (second rear connecting end B2) of the sixth link 306 and the second forceps arm 50 are synchronously driven by the fifth link 305 and the sixth link 306, so that the fifth link 305 and the hinged end (first rear connecting end A2) of the first forceps arm 40 and the hinged end (second rear connecting end B2) of the sixth link 306 and the second forceps arm 50 are synchronously opened outwards, and the first forceps arm 40 and the second forceps arm 50 are opened in parallel. When the application of the forward force to the control end D is stopped, the implant connected and fixed to the first and second arms 40 and 50 of the transfer actuator can apply opposing forces (for example, specifically, by providing an elastic member in a stretched state on the implant) to the first and second arms 40 and 50, under which forces the first and second arms 40 and 50 tend to approach each other and transition to the closed state. The process of transitioning to the closed state is similar to the process of transitioning the first and second jawarms 40, 50 to the open state described above and will not be described in further detail.
(2) Embodiments of the delivery device
In this embodiment, the transport device includes a controller and the transport actuator described in the above-described embodiments of the transport actuator.
The controller is used for controlling the state between the first and second clamp arms 40 and 50 of the conveying actuator, controlling the rotation of the swing base 20 relative to the base 10, and controlling the implant connected and fixed on the conveying actuator.
Specifically, the controller includes a first control mechanism, a second control mechanism, and a third control mechanism.
Based on the embodiment of the transport actuator shown in fig. 1 to 13, the first control mechanism is connected to the control end D of the link mechanism 30 of the transport actuator; as shown in fig. 14, the first control mechanism includes a first connection line L1 and a first receiving member (not shown), and the first connection line L1 is wound around the first receiving member and connected to the control terminal D. The first connecting line L1 may be a steel wire.
The first connecting line L1 is connected with the control end D, when the control end D is pulled by the first connecting line L1 and a pulling force towards the rear side is applied to the control end D, the distance between the first clamp arm 40 and the second clamp arm 50 is controlled to increase by acting on the connecting rod mechanism 30, and the distance tends to change towards the opening state; when the control end D is released from the first connection line and the control end D is no longer pulled backward, the distance between the first and second clamp arms 40 and 50 is reduced by the implant, and the closed state tends to be changed. The specific process has been described in detail in the above embodiment of the conveying actuator, and is not described again.
The first reel member may reel or release the first connecting line L1 by, for example, rotating. When the first connecting line L1 is wound by the first reel, the first connecting line L1 pulls the control end D to apply a pulling force towards the rear side to the control end D; when the first reel member releases the first connecting line L1, the first connecting line L1 correspondingly releases the control end D, and no longer applies a pulling force to the control end D toward the rear side.
The control end D of the first connection line L1 is connected, and specifically, one end of the first connection line L1 may be directly connected to the hinged end between the first link 301 and the second link 302. In addition, a stopper 204 may be connected to the first end of the first connection line L1, the stopper 204 is fixed by abutting against a fixing hole 202 formed in the swing seat 20, and the first connection line L1 passes through the fixing hole 202 and winds around the control end D, so that the first connection line L1 forms a pulley structure at the control end D.
The second control mechanism is connected to the swing base 20 for controlling the rotation of the swing base 20 relative to the base 10. As shown in fig. 15, the second control mechanism includes a second roll-in member (not shown) and at least two second connecting lines L2. The first ends of the at least two second connecting lines L2 are respectively connected to the first side and the second side of the swing seat 20, and the first side and the second side of the swing seat 20 are two sides of the hinge end between the swing seat 20 and the base 10 on the rotation path (in fig. 1 and 3, the two sides are the lower left side and the upper right side of the illustrated swing seat 20). Specifically, as shown in fig. 20, the stopper 205 is connected to the first end of the second connecting line L2, and the stopper 205 is fixed to the swing seat 20, so that the first end of the second connecting line L2 is fixed to the swing seat 20. The second end of the second connecting line L2 is wound around the second roll-up member.
Referring to fig. 1 and 3, when a second connecting line L2 connected to the first side of the swing seat 20 applies a pulling force to the first side of the swing seat 20, the swing seat 20 can be pulled to rotate in the first side direction; when the second connecting line L2 connected to the second side of the swing seat 20 applies a pulling force to the second side of the swing seat 20, the swing seat 20 can be pulled to rotate in the direction of the second side.
The number of the second rolling members may be one or more, and when the number of the second rolling members is one, the second ends of the second connecting lines L2 may be wound around the second rolling members, but the winding directions of the second connecting lines L2 connected to the first side and the second side of the swing seat 20 should be opposite, so that the second rolling members may rotate in different directions to apply pulling forces to the second connecting lines connected to the first side and the second side of the swing seat 20, respectively, thereby controlling the swing seat 20 to rotate in different directions.
The third control mechanism is connected with the implant connected and fixed on the conveying actuator and is used for controlling the state between the implant and the first clamp arm 40 and the second clamp arm 50 of the conveying actuator. Specifically, the third control mechanism includes a third connection line (not shown in the figure) including a first sub control line and a second sub control line; the first and second sub-control lines include a binding portion, a control portion, and a connecting portion connecting the binding portion and the control portion. The swing base 20 is provided with a fixing portion. The binding part of the first sub-control line movably binds the implant on the first clamp arm 40 at the first clamp arm 40, the control part is connected and fixed on the fixing part of the swing seat 20, and the control part is used for being triggered to unbind the binding part. The binding part of the second sub-control line movably binds the implant on the second clamp arm 50 at the second clamp arm 50, the control part is connected and fixed on the fixing part of the swing seat 20, and the control part is used for being triggered to unbind the binding part. Specifically, as shown in fig. 25 and 26, the fixing portion may be in the form of a wire casing 203, and the control portions of the first and second sub control lines are connected and fixed to the wire casing 203, for example, the fixing portion for fixing the first sub control line may be a wire casing 203d, and the fixing portion for fixing the second sub control line may be a wire casing 203e.
The first and second sub control lines bind the implant to the first and second clamp arms 40 and 50 of the transfer actuator before and during the movement of the implant to the target position. After the implant is moved to the target position, taking the auricle clamp as an example, the auricle clamp is moved to the left auricle to close the left auricle, and at the moment, the auricle clamp, the first clamp arm 40 and the second clamp arm 50 can be unbundled outside the human body through the control parts of the first sub-control line and the second sub-control line, so that the conveying actuator can be conveniently moved out of the human body after the implantation process of the implant is finished.
In an embodiment of the conveying apparatus, as shown in fig. 21 to 24, the second control mechanism may further include a connecting rod 206, a first end of the connecting rod 206 is connected to the swing seat 20, and a joint between the connecting rod 206 and the swing seat 20 is located outside a hinge axis between the swing seat 20 and the base 10, so that the first end of the connecting rod 206 acts on the swing seat 20 to rotate the swing seat 20 relative to the base 10. The second end of the link 206 is connected to a hand-held operation portion provided at the rear end of the transport apparatus. When the conveying device of this embodiment is used, the second end of the link 206 can be pulled or torn by the hand-held operation portion, and when the second end of the link 206 is moved by an external force, the corresponding force is transmitted to the first end of the link 206 and the swing seat 20, so that the swing seat 20 can be driven to rotate around the hinge axis between the swing seat and the base 10 in a predetermined direction.
In the present embodiment, as shown in fig. 25 and 26, the swing seat 20 is provided with a plurality of wire slots 203 for the first connecting wire, the second connecting wire, the third connecting wire, and the like to pass through or be connected and fixed. Specifically, in the present embodiment, the number of the wire slots 203 is 5, which are the wire slots 203a, 203b, 203c, 203d, and 203e, respectively. The wire slot 203a is used for a first connecting wire to pass through, the wire slot 203b and the wire slot 203c are respectively used for a second connecting wire connected with the first side and the second side of the swing seat 20 to pass through, and the wire slot 203d and the wire slot 203e are respectively used for a first sub-control wire and a second sub-control wire of a third connecting wire to be fixedly connected.
In the present embodiment, each of the trunking 203 includes a generally thin main body portion 2031, it is only necessary for the main body portion 2031 to be able to accommodate the first connecting wire, the second connecting wire, the third connecting wire, and the like, and, in the case of satisfying this requirement, the aperture of the main body portion 2031 may be as thin as possible so as to limit the swing amplitude of the first connecting wire, the second connecting wire, the third connecting wire, and the like. Among the plurality of wire grooves 203, at least a part of the tail ends of the wire grooves 203 are further provided with an opening portion 2032, and the width of the opening portion 2032 is generally larger in the hole diameter in the direction closer to the rear.
In the embodiment of the delivery device based on the delivery actuator shown in fig. 1-4, the wireway 203 may be as shown in fig. 27 and 28. Taking the wire groove 203d as an example, as shown in fig. 28, it includes a main body portion 2031 and an open portion 2032 for connecting and fixing the first sub control wire. When the swing base 20 is deflected to one side, the rear end of the swing base 20 is deflected to the side of the base 10, and at this time, the space between the swing base 20 and the base 10 is reduced, and accordingly, the space of the first sub control line is squeezed. However, in the case where the opening 2032 is provided along the rotation circumferential direction of the swing seat 20, the opening 2032 may form a notch for accommodating the first sub control wire at the position of the rear end of the swing seat 20, so that even when the swing seat 20 rotates such that the rear end thereof faces the side of the base 10, the first sub control wire is not caught between the base 10 and the swing seat 20, and the normal operation thereof is not affected.
In the embodiment of the conveying device based on the conveying actuator shown in fig. 1 to 4, at least two of the plurality of the wire grooves 203 may be disposed along the rotation circumferential direction of the swing seat 20, so that the at least two wire grooves 203 share the open portion 2032. As shown in fig. 25, the wire grooves 203a, 203b, and 203c are arranged along the rotation circumference of the swing seat 20, and all three have a common open portion 2032. This can reduce the number of grooves formed on the rear end of the swing seat 20, thereby enabling saving of processing time and processing cost.
As described above, as shown in fig. 28, in conjunction with fig. 25 and 26, the swing seat 20 has a first side and a second side, which are two sides of the hinge end between the swing seat 20 and the base 10 on the rotation path. The open portion 2032 of the linear groove 203 on the first side of the swing seat 20 is located on the second side of the main body 2031 of the linear groove 203; the open portion 2032 of the linear groove 203 on the second side of the swing seat 20 is located on the first side of the body portion 2031 of the linear groove 203. With this arrangement, for the trunking 203 located on the first side of the swinging seat 20, a partial structure of the swinging seat 20 on the first side of the main body portion 2031 of the trunking 203 can be retained; for the trunking 203 located at the second side of the swing seat 20, a partial structure of the swing seat 20 at the second side of the main body portion 2031 of the trunking 203 may be retained. The remaining structures on the swing seat 20 do not interfere with the connection lines passing through the wire slots 203 during the rotation of the swing seat 20, and the remaining structures can enhance the structural strength of the rear end of the swing seat 20, especially the structural strength in the direction perpendicular to the rotation plane of the swing seat 20.
In the embodiment of the conveying apparatus based on the conveying actuator shown in fig. 10 to 13, the wire duct 203 may be as shown in fig. 29 to 32. Taking the trunking 203d as an example, as shown in fig. 32, it includes a main body portion 2031 and an open portion 2032 for connecting and fixing the first sub-control line. When the swing base 20 is deflected to one side, the rear end of the swing base 20 is deflected to the side of the base 10, and at this time, the space between the swing base 20 and the base 10 is reduced, and accordingly, the space of the first sub control line is squeezed. However, in the case where the opening 2032 is provided along the rotation circumferential direction of the swing seat 20, the opening 2032 may form a notch for accommodating the first sub control wire at the position of the rear end of the swing seat 20, so that even when the swing seat 20 rotates such that the rear end thereof faces the side of the base 10, the first sub control wire is not caught between the base 10 and the swing seat 20, and the normal operation thereof is not affected.
