Description

Instrument assembly clamping detection mechanism, clamping detection method and instrument assembly thereof

Technical Field

The invention relates to the field of mechanical structures, in particular to a clamping detection mechanism and method for an instrument assembly and the instrument assembly.

Background

Minimally invasive medical techniques have been used to reduce the amount of external tissue that may be damaged during diagnostic or surgical procedures, thereby reducing patient recovery time, discomfort, and adverse side effects. The surgical instruments are similar to those used in conventional (open) surgery, except that an extension tube, for example, approximately 30cm long, separates the working end or end effector of each surgical instrument from its handle to allow an operator to introduce the end effector to the surgical site and control movement of the end effector relative to the surgical site from outside the patient.

The surgeon may manipulate controls at the console to indirectly manipulate instruments connected to the remote control actuators. The surgical instrument is detachably coupled to the teleoperated actuator so that the surgical instrument can be individually sterilized and selected for use as an instrument required for the surgical procedure to be performed. During surgery, surgical instruments may be replaced.

The challenge with teleoperated surgical systems is that the surgeon typically employs several different surgical instruments during the procedure. Many different surgical instruments are typically introduced through the same trocar sleeve during a surgical procedure to limit the number of incisions required. Thus, the number of instrument holders available is limited, often less than the number of surgical instruments used during the procedure. Thus, surgical instruments may be attached and detached from the same instrument holder multiple times during the surgical procedure.

Many connections are required between the surgical instrument and the remote actuator and its controller. Connections are required to communicate actuator forces, electrical signals and data. This complicates the attachment of surgical instruments to the remote actuator and its controller, and typically employs a snap-fit connection when connected, with conventional clamping methods having no status recognition that would be an unsuccessful and risky problem.

A second buckle 321 is arranged at a position corresponding to the second clamping groove 211 formed on the device seat fixing plate 21 on the upper end surface of the upper adapting plate 32, and an inwardly inclined matching surface 3211 is arranged at the outer side of the tail end of the second buckle 321.

As shown in fig. 6 and 9, a receiving block 312 is arranged on the adapting lower plate 31 at a position corresponding to the instrument detection assembly on the motor base, and a through hole 3121 for penetrating the movable end of the instrument detection assembly is arranged in the middle of the receiving block 312; an identification groove 325 is arranged on the lower end surface of the upper adapting plate 32 at a position corresponding to the accommodating block 312 on the lower adapting plate 31, and the identification groove 325 and the accommodating block 312 are correspondingly matched to form an accommodating cavity for accommodating the identification key 15 of the instrument detection assembly, as shown in fig. 9; the position of the upper adapting plate 32 corresponding to the through hole 3121 of the lower adapting plate 31 is provided with an identifying hole 324, the identifying key 15 is of a ladder structure, the front end of the identifying key is consistent with the identifying hole 324, and the rear end of the identifying key is larger than the front end of the identifying key, so that the identifying key 15 can only move in the direction perpendicular to the upper adapting plate 32 in the accommodating cavity formed by the identifying groove 325 and the accommodating block 312; when the micro switch 13 of the instrument detection assembly is in a natural state, the front end of the micro switch 13 sequentially passes through the first detection through hole 14 on the motor base fixing plate 11 and the through hole 3121 on the adapting lower plate 31 and is propped against the rear end of the identification key 15, the identification key 15 is propped up in the identification groove 325 under the elastic force of the micro switch 13 in the natural state, and the front end of the micro switch extends out of the identification hole 324 on the adapting upper plate 32, as shown in fig. 14.

As shown in fig. 6, a protrusion 3112 is formed to extend inward at a position corresponding to the identification key 15 inside the pressing block 311, and the protrusion 3112 moves inward, i.e., in a direction approaching the identification key 15 when the pressing block 311 is in a deformed state; as shown in fig. 9, a groove is formed in the position, corresponding to the protrusion 3112, on the identification groove 325 on the lower end face of the upper adapting plate 32, so that when the first buckle 313 and the first clamping groove 16 are in attempt to be clamped and connected successfully, the protrusion 3112 can abut against the side face of the identification key 15 when the pressing block 311 is in the deformation state and moves inwards, and therefore the identification key 15 cannot be jacked up by the movable end of the micro switch 13 due to the fact that the first buckle 313 and the first clamping groove 16 are not clamped successfully when the lower adapting plate 31 is installed under the action of friction force between the identification key 15 and the protrusion 3112, as shown in fig. 11;

further, as shown in fig. 6, the thickness of the accommodating block 312 is smaller than that of the lower adapting plate 31, and the lower end surface of the accommodating block may be designed to be flush with the lower end surface of the lower adapting plate 31, so as to form a groove for placing the identification key 15, the protrusion 3112 is disposed corresponding to the identification key 15, and when the first buckle 313 and the first slot 16 attempt to be engaged but not succeeded, the pressing block 311 abuts against the side surface of the identification key 15.

As shown in fig. 12, a sterile cover 34 for sleeving the motor base 1 is further arranged between the upper adapting plate 32 and the lower adapting plate 31, and a matching through hole 341 is formed in the sterile cover 34 at a position corresponding to the output shaft of the motor base, and the diameter of the matching through hole 341 is slightly smaller than the outer diameter of the adapter 33, as shown in fig. 13; the lower part of the adapter piece 33 extends outwards along the radial direction to form a mounting ring, a first bulge which is correspondingly matched with a first groove on the spline cap 12 is arranged on the end surface of the mounting ring matched with the spline cap 12, and a second bulge which is matched and butted with the second groove is arranged at the position of the upper end surface of the adapter piece 33 corresponding to the second groove arranged on the input shaft of the instrument seat; the adaptor 33 sequentially passes through the adaptor through hole on the lower adapting plate 31 and the matching through hole 341 on the sterile cover 34, and is arranged in the accommodating hole of the upper adapting plate 32, so that interference fit is formed with the sterile cover 34.

In the present invention, in order to ensure a sterile environment for surgery, the adapter 3 adopts a sterile disposable structure, before the instrument seat of the present invention is used, sterilization is needed, but the motor seat cannot be sterilized by conventional methods (such as steam, heating and pressure or chemical) because the motor, the sensor and the encoder which control the instrument assembly in the motor seat can be damaged or destroyed in the sterilization process, and therefore, the motor seat needs to be isolated from the sterile environment by the sterile cover 34; after the operation is finished, the adapter 3 of the invention is directly disassembled and scrapped.

Fig. 15 is a schematic view of an instrument seat fixing plate according to the present invention, as shown in fig. 15, a through hole for penetrating an input shaft of an instrument seat is formed in the instrument seat fixing plate 21; a second clamping groove 211 is formed in the instrument seat fixing plate 21 at a position corresponding to the first clamping groove 16 formed in the motor seat fixing plate 11 and is used for being clamped with the upper adapting plate 32 of the adapter 3;

fig. 16 is a schematic view of an apparatus mounting plate according to the present invention, as shown in fig. 16, an apparatus seat mounting plate 22 is fixedly mounted on an apparatus seat fixing plate 21 by bolts, a key chute 221 extending in an inner and outer direction is provided on a lower end surface thereof at a position corresponding to a second clamping groove 211 on the apparatus seat fixing plate 21, and a key 222 is slidably mounted therein; more specifically, the key 222 includes a sliding portion 2222 slidably disposed in the key slide groove 221, a key portion 2221 fixedly connected to an outer end of the sliding portion 2222, and a connecting portion 2223 fixedly connected to an inner end of the sliding portion 2222, as shown in fig. 17; the connecting parts 2223 of the keys 222 arranged at the two sides of the instrument seat mounting plate 22 are connected through the tension springs 223, and the sliding limit of the sliding part 2222 in the key sliding groove 221 can be realized through the matching limit between the key parts 2221 and the connecting parts 2223 and the key sliding groove 221, and the key parts 2221 of the two keys 222 move towards the inside of the instrument seat under the action of the tension springs 223 and are limited under the action of the two side surfaces of the instrument seat mounting plate 22, so as to shrink to the two sides of the instrument seat mounting plate 22, namely the first position of the key 22 at the moment; an engaging portion 2224 that engages with an engaging surface 3211 on the second catch 321 is provided on the key portion 2221 or on the outer end of the slide portion 2222 at a position corresponding to the second catch 321 on the upper mating plate 32, as shown in fig. 18, and when the tension spring 223 is in its initial state, i.e., the instrument holder 2 is not engaged with the adapter 3, the key 222 is retracted to its first position, as shown in fig. 19, 20. When the device seat 2 and the adapter 3 attempt to be clamped but are unsuccessful, that is, the second buckle 321 and the second clamping groove 211 attempt to be clamped but are unsuccessful, the second buckle 321 deforms to move towards the interior of the device seat 21, and at this time, the matching surface 3211 on the second buckle 321 is not contacted with the matching part 2224 of the key 222, so that the key 222 is kept at the first position under the action of the tension spring 223. When the instrument seat 2 and the adapter 3 are successfully assembled, that is, the second buckle 321 and the second clamping groove 211 are successfully clamped, the matching surface 3211 on the second buckle 321 is matched with the matching part 2224 on the key 222, so that the second buckle 321 overcomes the tension force of the tension spring 223 to move outwards with the key 222, and at the moment, the second position of the key 22 is the second position of the key 22. The invention judges whether the installation of the instrument seat 2 and the adapter 3 is successful (namely, whether the clamping of the second clamping buckle 321 and the second clamping groove 211 is successful) through the position change of the key 22.

In the invention, the instrument seat 21 is provided with a shell, and the shell of the instrument seat 21 is provided with an opening at a position corresponding to the key 222;

further, the size of the opening may be designed to be smaller than the size of the key portion 2221 of the key 222, so that when the key 222 is retracted inward to both sides of the instrument seat mounting plate 22 under the action of the tension spring 223, the key portion 2221 thereof is just abutted against the housing; and when the second buckle 321 moves outwards with the key 222 against the tension of the tension spring 223, the key part 2221 of the key 222 protrudes out of the casing of the instrument seat 21.

Further, the size of the opening is designed to be capable of penetrating through the key portion 2221 of the key 222, so that when the key 222 is retracted inwards to both sides of the instrument seat mounting plate 22 under the action of the tension spring 223, the key portion 2221 can be retracted into the housing; when the second buckle 321 moves outwards to the second position of the key 222 with the key 222 against the tension of the tension spring 223, the outer surface of the key portion 2221 of the key 222 is just flush with the outer shell of the instrument seat 21.

In the present invention, the engaging portion 2224 is designed as an inclined surface corresponding to the engaging surface 3211 on the second catch 321; however, the present invention is not limited thereto, and one of the engaging portion 2224 and the engaging surface 3211 of the second catch 321 may be configured as a corresponding inclined surface, and the other may be configured as a vertical surface or a corresponding inclined surface.

Specifically, two sliding grooves corresponding to two sides of the sliding portion 2222 of the key 222 are provided on the lower end surface of the instrument seat mounting plate 22, and the sliding portion 2222 of the key 222 is slidably mounted on the sliding grooves through two sides thereof;

more specifically, a corresponding guide groove or guide rail may be provided on the lower end surface of the instrument holder mounting plate 22, and correspondingly, a guide rail or guide rail to be engaged with the sliding portion 2222 of the key 222 is provided, so that the sliding mounting of the key 222 is achieved.

The working principle of the invention is as follows:

pressing down the adapter 3 towards the direction of the motor base fixing plate 11, if the installation of the adapter 3 is unsuccessful, namely the clamping fit of the first buckle 313 and the first clamping groove 16 is unsuccessful, the pressing block 311 deforms to enable the protrusion 3112 on the pressing block to be abutted against the side surface of the identification key 15, the identification key 15 of the instrument identification component applies pressure to the micro switch 13 and enables the micro switch 13 to retract under the action of friction force between the identification key 15 and the protrusion 3112 of the pressing block 311, so that the micro switch 13 is in a triggering state, meanwhile, the micro switch 13 of the adapter detection component is pressed down by the adapting lower plate 31 and is also in a triggering state, and at the moment, the controller of the instrument component detects that the two pairs of micro switches 13 are triggered within 3 seconds, the adapter installation is judged to be unsuccessful, and error information is prompted through sound and light; theoretically, the two pairs of micro switches 13 should be triggered simultaneously to determine that the adapter is not successfully installed, but a certain time difference may be caused after the micro switches 13 are triggered due to the problem of the installation angle, so in this embodiment, the two pairs of micro switches 13 are triggered within 3 seconds to determine that the adapter is not successfully installed; if the first buckle 313 and the first clamping groove 16 are successfully clamped and matched, the pressing part 311 is reset immediately after being deformed, and the identification key 15 is quickly sprung up under the action of the micro switch 13, so that the micro switch 13 is restored to an un-triggered state; at this time, whether the lower adapting plate 31 is clamped in place or not can be judged according to the triggering states of the instrument detection assembly and the adapter detection assembly, and the lower adapting plate is sent to the controller in the motor base 1, whether the adapter is installed or not, whether the instrument is installed or not and whether the adapter is installed successfully or not are judged by the controller according to the received triggering signals of the instrument detection assembly and the adapter detection assembly, and corresponding indication is provided, for example, when the adapter is installed on the motor base but not installed successfully (namely, the first buckle 313 and the first clamping groove 16 are in clamping attempt but not clamping and matching successfully), the acousto-optic generator is controlled to send out acousto-optic prompt error information and corresponding text prompt error information is sent out on the display;

when the first buckle 313 of the lower end surface of the lower plate 31 is matched with the first clamping groove 16 on the motor base fixing plate 11, the micro switch 13 of the instrument detection assembly is in an un-triggered state; meanwhile, the micro switch 13 of the adapter detection assembly is still in a trigger state, so that the adapter lower plate 32 is judged to be clamped in place, namely the adapter 3 is clamped in place;

the front two keys 222 of the instrument seat 2 are contracted to the outer surfaces of the two sides of the instrument seat 2 under the action of the tension springs 223. When the instrument seat 2 is mounted, the second buckle 321 of the upper adapting plate 32 is clamped with the second clamping groove 211 on the instrument seat fixing plate 21, and the key 222 is in a pressed state when the clamping is unsuccessful. When the second buckle 321 is locked in place, the mating surface 3211 at the end of the second buckle 321 mates with the mating portion 2224 on the key 222 to eject the key 222 outwards, so that the instrument seat can be confirmed to be locked in place when the key 222 is ejected.

The invention solves the problem that the traditional clamping mode has no state identification, and certain clamping is unsuccessful to operate, thereby ensuring the safety.
