The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art. The technical solution of the present invention will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Referring to fig. 1, the medical apparatus according to the first embodiment of the present invention comprises a propelling device 10, a rotating device 20 movably disposed on the propelling device 10, a holding device 30 rotatably disposed on the rotating device 20, a holding device 40 fixed on the propelling device 10, and a fixing device 50 fixed on the propelling device 10.

The rotating device 20 is used for rotating the clamping device 30. The holding device 30 is used for holding an object 60 (such as a guide wire or a catheter), the holding device 40 is also used for holding the object 60, the object 60 is adapted to pass through the holding device 30 and the holding device 40 in sequence along the delivery direction of the object, and the holding device 30 moves relative to the advancing device 10 under the condition that the holding device 40 and the holding device 30 are alternately held, so that the delivery of the object 60 is realized.

The fixture 50 is used to anchor another object (e.g., a catheter) mounted on the object 60. In case of the fixation means 50 being provided, said object 60 is adapted to pass the holding means 30, the holding means 40 and the fixation means 50 in sequence along its delivery direction. The medical device of the present embodiment is particularly suitable for interventional procedures.

Referring to fig. 2 to 4, in the present embodiment, the rotating device 20 includes a frame 24, a supporting base 26 rotatably connected to the frame 24, and a driving mechanism 21 disposed on the frame 24 for driving the supporting base 26 to rotate, wherein a clamping device 30 is disposed in the supporting base 26.

The frame 24 is provided with a guide 242, the support base 26 is provided with a guide rail 22, and the guide 242 is arranged at the edge of the guide rail 22 and is connected with the guide rail 22 in a sliding manner. Compared with the conventional rotating device which simulates the twisting and rotating of the guide wire by the fingers using a friction wheel, a clamp plate, or the like, the rotating device 20 of the present embodiment rotates the support base 26 via the guide rail 22, and further rotates the target 60 held by the holding device 30. In other words, in the embodiment, the rotation of the object 60 is realized by the rotating device 20, and the clamping of the object 60 is realized by the clamping device 30, and the rotation and the clamping of the object 60 are realized by the rotating device 20 and the clamping device 30 which are independent of each other, so that the problems of object slipping and the like caused by the simultaneous rotation and clamping of the object by the same device (such as the device simulating the finger kneading) in the prior art are effectively reduced. In particular, the guide rail 22 is slidably connected with the guide 242, so that the guide rail 22 defines the moving path thereof through the guide 242, and the guide rail 22 rotates along the fixed moving path without deviation, thereby further reducing the risk of slipping of the target 60 (such as a guide wire), and the target 60 rotates stably and precisely.

In this embodiment, the supporting seat 26 is substantially cylindrical, and includes a circular plate-shaped connecting frame 261 and a hollow cylindrical housing 262, wherein the connecting frame 261 and one end of the housing 262 are fixedly connected to form a cavity for accommodating the clamping device 30, the guide rail 22 is fixed on the periphery of the connecting frame 261 and faces away from the housing 262, and the guide rail 22 and the clamping device 30 are respectively located on two opposite sides of the connecting frame 261. Preferably, a first opening 263 is arranged on the connecting frame 261, the first opening 263 is composed of a small sector and a large sector, wherein the small sector takes the center of the connecting frame 261 as a circle center, the large sector extends from two ends of the small sector to the edge of the connecting frame 261 respectively, the guide rail 22 is designed to avoid the first opening 263, and the rotation center of the guide rail 22 coincides with the center of the connecting frame 261. Correspondingly, the outer shell 262 is provided with a second opening 264 aligned with and communicating with the first opening 263, and the shape of the second opening 264 is identical to that of the first opening 263. The first opening 263 and the second opening 264 together form an opening 300, and the target 60 (such as a guide wire) can be quickly assembled and disassembled through the opening 300 without artificial threading, so that the problem that the operation effect is influenced due to complicated assembly and disassembly is avoided particularly under the condition that the operation robot breaks down. It is understood that in other embodiments, the first opening 263 and the second opening 264 may have other shapes, such as V-shape, Y-shape, etc.

In this embodiment, the guide rail 22 is in the shape of a circular arc, the rotation center of the guide rail 22 is the center of the circular arc, and the center of the circle is located in the opening 300. In this embodiment, the extension angle of the guide rail 22 is a reflex angle. The circular arc-shaped guide rail 22 ensures that the rotation center position of the supporting seat 26 is determined and the rotation is stable.

In the present exemplary embodiment, the clamping device 30 has at least two clamping jaws 31. The at least two jaws 31 have a clamped state and an open state. In the clamped state, the at least two clamping jaws 31 clamp the object 60. In the open state, an entrance 32 (shown in fig. 4) is formed between the at least two jaws 31, and the entrance 32 at least partially coincides with the opening 300, so that the object 60 can be taken out from the entrance 32 through the opening 300, or can be placed between the at least two jaws 31 through the opening 300 and the entrance 32 for clamping. Preferably, the clamping center of at least two clamping jaws 31 is concentric with the rotation center of the supporting seat 26, so as to avoid bending and twisting of the target object during rotation.

Preferably, the driving mechanism 21 includes a motor 210 and a transmission mechanism for connecting the motor 210 and the guide rail 22, and the motor 210 drives the guide rail 22 to rotate through the transmission mechanism. The transmission mechanism includes a gear 211 driven by the output shaft of the motor 210 to rotate, and a ring gear 221 provided on the outer edge of the guide rail 22. The gear 211 is in meshed connection with the gear ring 221. When the driving mechanism is operated, the motor 210 drives the gear 211 to rotate, and the gear 211 drives the guide rail 22 to rotate through the gear ring 221, so as to drive the supporting seat 26, the clamping device 30 and the target object 60 thereon to rotate. The rotation angle of the object 60 is made more accurate by the meshing connection of the ring gear 221 and the gear 211. It will be appreciated that in other embodiments, the gear ring 221 may be disposed at other positions, as long as it is disposed at the circumferential edge of the guide rail 22 or the support seat 26.

Preferably, in this embodiment, the transmission mechanism further includes a speed reducer 212 connected to the output shaft of the motor 210, and a pulley set 213 connected to the output end of the speed reducer 212. The gear 211 is connected with the output end of the pulley set 213. The reduction gear 212 reduces the rotation speed of the motor 210, and the pulley set 213 steers and outputs the power of the motor 210, thereby optimizing the spatial layout of the rotating device 20 and making the structure of the rotating device 20 more compact. Alternatively, the pulley set 213 may be replaced by a gear set. As shown in fig. 3, the pulley group 213 of the present embodiment includes a driving pulley 214 connected to an output end of the reducer 212, a driven pulley 215 connected to the gear 211, and a transmission belt 216 connected between the driving pulley 214 and the driven pulley 215.

In this embodiment, the frame 24 includes a hollow housing 231 having a substantially square shape, a bottom plate 232 fixedly coupled to the bottom of the hollow housing 231, and a support plate 233 fixedly coupled to the bottom plate 232. The support seat 26 is partially housed in the hollow case 231. The pulley set 213 is installed at one side of the support plate 233, and the motor 210, the reducer 212, and the gear 211 are installed at the other side of the support plate 233.

Preferably, the clamping device 30 and the transmission mechanism are respectively disposed on two opposite sides of the supporting seat 26, and the transmission mechanism and the guide rail 22 are disposed on the same side of the supporting seat 26. The reason for this is that: the clamping device 30 is connected with connecting wires (such as wires) for connecting with a motor, and the clamping device 30 is arranged on the rotating device 20 so that the rotating device 20 drives the clamping device to rotate 30, therefore, the design of leading the connecting wires to the clamping device 30 through the rotating device is more reasonable, and the connecting wires are wires with bending allowance rather than a straight wire as the rotating device 30 needs to rotate; however, a transmission mechanism is provided in the rotating device 20; therefore, if the clamping device 30 and the transmission mechanism are provided on the same side of the support base 26, these connecting wires will directly contact the transmission mechanism and easily get tangled, causing an accident. In the embodiment, the clamping device 30 and the transmission mechanism are arranged on the two sides of the supporting seat 26 in the opposite directions, and the transmission mechanism is arranged on the side edge of the clamping device 30 far away from the connecting line, so that the connecting line is prevented from contacting with the transmission mechanism, the whole structure is compact, and the size of the rotating device is reduced.

As shown in fig. 4 and 5, in the present embodiment, the guide 242 is configured as a bearing 242. The frame 24 also includes a mounting plate 241, and one or more bearings 242 are fixedly mounted (e.g., by screws) to the mounting plate 241. The mounting plate 241 is fixedly mounted to the base plate 232 (e.g., by screws). The one or more bearings 242 are supported on the inner periphery 222 and/or the outer periphery 223 of the rail 22. The bearing 242 has a small friction coefficient, and can perform precise limiting and guiding functions on the guide rail 22, and the friction coefficient is small, so that the rotation stability and precision of the guide rail 22 can be improved. Preferably, at least one bearing 242 is disposed on both the inner periphery 222 and the outer periphery 223 of the guide rail 22 to further enhance the retaining and guiding function of the guide rail 22. In this embodiment, two upper bearings 242A are disposed on the inner periphery 222 of the guide rail 22, and two lower bearings 242B are disposed on the outer periphery 223 of the guide rail 22. It is also preferable that a connecting line of the axes of the two upper bearings 242A and the two lower bearings 242B is trapezoidal, wherein the two upper bearings 242A are respectively located on two sides of the center line L (a connecting line of the midpoint of the guide rail 22 and the center O corresponding thereto), and the two lower bearings 242B are located on two sides of the center line L. In other words, the distance between the two upper bearings 242A is smaller than the distance between the two lower bearings 242B, and the connecting lines of the axes of the upper bearing 242A and the lower bearing 242B on the same side of the center line L pass through the center O. This helps to improve the stability of the support of the guide rail 22 by the bearing 242.

Referring to fig. 5 and 6, it is also preferable that an inner flange 224 and an outer flange 225 are formed to protrude from the inner circumference 222 and the outer circumference 223 of the guide rail 22, respectively. The upper bearing 242A is formed with an upper groove 243A that is fitted with the inner flange 224. The lower bearing 242B has a lower groove 243B formed therein that mates with the outer flange 225. The guiding and limiting effect of the bearing 242 on the guide rail 22 can be further improved by the cooperation of the flange and the groove. More preferably, the axial section of the inner flange 224 is an inverted V-shape, and correspondingly, the axial section of the upper groove 243A is also an inverted V-shape; the outer flange 225 has a V-shaped axial cross-section and correspondingly the lower groove 243B has a V-shaped axial cross-section. The co-operation of the flanges and grooves of the V-shaped or inverted V-shaped design allows only one degree of freedom of rotation of the guide rail 22, and the accuracy of the rotation of the guide rail 22 is high. It will be appreciated that in other embodiments the axial cross-section of the groove and flange may take other shapes, such as U-shaped, H-shaped, etc.

It will be appreciated that in other embodiments, grooves may be formed in the rail and flanges may be formed on the bearings, as well as precise location and guidance of the rail.

It will also be appreciated that in other embodiments, the rail 22 may be secured to a clamping device in other configurations and/or the rail may take other configurations.

For example, as shown in fig. 7, a support base 330 of a medical device according to a second embodiment of the present invention has a substantially Y-shape, rather than a substantially cylindrical structure, as compared with the support base 26 of the first embodiment. However, similar to the support seat 26 of the first embodiment, the support seat 330 of this embodiment also has an opening 331 opening from its periphery toward its center. The object 60 is adapted to be clamped to or released from the clamping device via the opening 331. It can be seen that the present embodiment also allows for quick and easy loading and unloading of the object 60, particularly in the event of a medical device failure.

In addition, the circumferential extension angle of the guide rail 322 of the rotating device of the present embodiment is also smaller than 360 ° to avoid the influence of the guide rail 322 on the mounting and dismounting of the target 60. However, unlike the reflex angle of the guide rail 22 in the first embodiment, the extension angle of the guide rail 322 in the present embodiment is substantially 180 °.

In the present application, unless expressly stated or limited otherwise, the first feature "on" or "under" the second feature may be directly contacting the first feature or the second feature or indirectly contacting the first feature or the second feature through an intermediate.

Also, a first feature "on," "above," and "over" a second feature may mean that the first feature is directly above or obliquely above the second feature, or that only the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lower level than the second feature.
