Description

Technical Field

[0001] The present disclosure relates to a handle assembly, a tube assembly, an actuator assembly and a medical device. Background Art

[0002] Laparoscopic staplers can be used to sever, resect and / or establish anastomosis of organs, tissues or blood vessels in the body, and are suitable for a variety of open or minimally invasive surgeries. Generally speaking, a laparoscopic stapler includes an operating assembly, a longitudinally extending shaft assembly and a distal actuator. In minimally invasive surgery, the laparoscopic stapler enters the channel in the patient's body through a puncture device and performs corresponding operations. The electric staplers currently on the market are generally instruments with fixed cutting suture lengths. When using staple cartridges with different cutting suture lengths, the instrument needs to be replaced; alternatively, the electric stapler can replace actuator assemblies with different cutting suture lengths, such as a disposable actuator assembly (single-use loading unit or SULU), but the operator needs to select the gear on the instrument that matches the actuator assembly of this model to perform the corresponding operation. The operation is complicated and the human-computer interaction is poor. Utility Model Content

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0034] Unless otherwise defined, the technical or scientific terms used in this disclosure should have the usual meanings understood by persons of ordinary skill in the field to which this disclosure belongs. The words "first", "second" and similar terms used in this disclosure do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0035] In embodiments of the present disclosure, the term "proximal" refers to a portion of the involved component or structure that is close to the clinician, and the term "distal" refers to a portion of the involved component or structure that is away from the clinician. The term "plurality" refers to two or more.

[0036] In some embodiments, the stapler actuator typically has different models depending on the length of the cut suture, such as 30 / 45 / 60 models, representing three staple line lengths of 30mm, 45mm, and 60mm, respectively, to meet different clinical needs. Currently, electric staplers on the market generally have fixed cut suture lengths. When a stapler cartridge with a different cut suture length is needed, the instrument needs to be replaced. Alternatively, electric staplers have replaceable actuator assemblies for different cut suture lengths, but the operator needs to select the gear on the instrument that matches the actuator assembly model to perform the corresponding operation, which is complicated and has poor human-computer interaction.

[0037] At least one embodiment of the present disclosure provides a handle assembly for a medical device, the handle assembly including a shell, a power device and a transmission assembly, the shell including an internal cavity, the power device being detachably disposed in the cavity, including an identification device, the identification device including an identification mating portion, the transmission assembly being movably disposed on the shell, the proximal end of the transmission assembly being connected to the identification mating portion, the identification mating portion being configured to be pushed a characteristic distance by the transmission assembly, and the identification device being configured to emit a corresponding identification signal based on the characteristic distance.

[0038] At least one embodiment of the present disclosure provides a tube body assembly for a medical device, the medical device including a handle assembly, the tube body assembly including a tube body and a first transmission assembly, the first transmission assembly being arranged in the tube body and including a third push block, a push connecting rod and a rotating push member, the distal end and the proximal end of the push connecting rod being connected to the third push block and the rotating push member respectively, the rotating push member including a rotating connection portion circumferentially connected to the push connecting rod and a linear pushing portion abutting against the handle assembly.

[0039] At least one embodiment of the present disclosure further provides an actuator assembly for a medical device, the actuator assembly including an actuator module and a connecting head disposed proximal to the actuator module, wherein the connecting head has a characteristic length.

[0040] At least one embodiment of the present disclosure also provides a medical device, which includes a handle assembly provided by an embodiment of the present disclosure, a tube body assembly provided by an embodiment of the present disclosure, and an actuator assembly provided by an embodiment of the present disclosure, wherein the transmission assembly of the handle assembly is a second transmission assembly; the actuator assembly is detachably connected to the distal end of the tube body assembly, the distal end of the third push block abuts against the connecting head, the handle assembly is detachably connected to the proximal end of the tube body assembly, and the connecting head pushes the identification mating part a characteristic distance through the first transmission assembly and the second transmission assembly, and the characteristic distance corresponds to the characteristic length.

[0041] In the medical device provided by the embodiment of the present disclosure, the identification device can send a corresponding identification signal according to the characteristic length of the connecting head of different models of actuator assemblies, and then formulate an operation for the actuator assembly based on the identification signal, thereby realizing the identification and operation of different actuator assemblies, and realizing the connection and control of different models of actuator assemblies by the same operating handle assembly to perform corresponding operations; in addition, the medical device includes multiple transmission assemblies, which are respectively arranged in multiple detachable and connected assemblies of the medical device and connected and matched, so as to facilitate the disassembly and connection between multiple components, such as facilitating the disassembly and connection between the tube body assembly, the shell and the power device, and facilitating use.

[0042] The handle assembly, tube assembly, actuator assembly and medical device provided by the embodiments of the present disclosure are described below through several specific embodiments.

[0043] At least one embodiment of the present disclosure provides a medical device, Figure 1 shows a schematic diagram of the three-dimensional structure of the medical device, Figure 2 shows a schematic diagram of the three-dimensional structure of the handle assembly of the medical device, Figure 3 The schematic diagram of the structure of the transmission component of the medical device is shown in FIG. Figure 1-Figure 3 As shown, the medical device includes a tube body assembly 10 and a handle assembly 30, and for example, further includes an actuator assembly SU and other structures. The actuator assembly SU is, for example, a disposable loading device or a multiple-use loading unit and other structures.

[0044] like Figure 1 and Figure 3 As shown, the pipe assembly 10 includes a pipe body and a first transmission assembly 10A disposed in the pipe body. The distal end of the pipe assembly 10 ( Figure 1 The left end in FIG) is configured to connect the actuator assembly SU, the distal end of the first transmission assembly 10A ( Figure 3 The left end of the tube assembly 10 is connected to the connecting head 21 of the actuator assembly SU; the handle assembly 30 is provided at the proximal end of the tube assembly 10 ( Figure 1 At the right end in FIG, the handle assembly 30 includes a housing 31, a power device 32, a second transmission assembly 33 and other structures. The handle assembly 30 can be grasped by the operator to perform the anastomosis operation.

[0045] For example, Figure 4 The schematic diagram of the structure of the power unit is shown in FIG. Figure 3 and Figure 4 As shown, the interior of the shell 31 includes a cavity, that is, the space inside the shell 31 (not shown in the figure). The shell 31 is, for example, a sterile disposable protective shell. The power device 32 is detachably arranged in the cavity, so that it is sealed and isolated by the shell 31, preventing bacteria on the power device 32 from being transmitted out of the shell 31, preventing harmful substances such as pathogens that may exist on the power device 32 from contaminating the operating environment and the operator's hands, etc., thereby improving the safety of the surgical process and facilitating the reuse of the power device 32.

[0046] For example, the power unit 32 includes an identification device 321, for example, for identifying the model of the installed actuator assembly SU to determine the required operation. Figure 5 A schematic diagram of a part of the structure of the identification device is shown in FIG. Figure 4 and Figure 5 As shown, the identification device 321 includes an identification matching portion 322; Figure 2 and Figure 3 The second transmission assembly 33 is movably provided on the housing 31, and the distal end of the second transmission assembly 33 ( Figure 3 The left end of the first transmission assembly 10A) and the proximal end of the first transmission assembly 10A ( Figure 3The right end of the second transmission assembly 33 is connected to the proximal end ( Figure 3 The right end of the second transmission assembly 33 is connected to the identification mating portion 322. The identification mating portion 322 is configured to be pushed a characteristic distance by the second transmission assembly 33, and the identification device is configured to emit a corresponding identification signal based on the characteristic distance. For example, the connecting head 21 of the actuator assembly SU can sequentially apply a pushing force to the identification mating portion 322 through the first transmission assembly 10A and the second transmission assembly 33, thereby triggering the identification device 321 to emit a corresponding identification signal.

[0047] For example, the actuator assembly includes an actuator module (such as a cutting assembly, a suturing assembly, and other structures) and a connecting head disposed proximal to the actuator module, and the connecting head has a characteristic length.

[0048] For example, Figure 6 A schematic diagram of the structure of the actuator assembly is shown in FIG. Figure 3 and Figure 6 As shown, the connecting head 21 has a characteristic axial length D, so that the connecting head 21, through the first transmission assembly 10A and the second transmission assembly 33, pushes the identification mating portion 322 a characteristic distance, and the identification device 321 is configured to issue a gear position signal based on the characteristic distance. For example, in an embodiment of the present disclosure, the identification mating portion 322 is configured to be pushed by the connecting head 21 by a characteristic distance, so that the identification device 321 is in different gear positions, thereby issuing corresponding identification signals.

[0049] For example, Figure 7-Figure 9 Shows some structural diagrams of actuator components of different models, such as Figure 7 As shown, the connecting head 21 of the actuator assembly SU has a characteristic length D1. Therefore, after the actuator assembly SU is connected to the tube body assembly 10, the connecting head 21 can push the identification mating portion 322 a characteristic distance D1 via the first transmission assembly 10A and the second transmission assembly 33. At this time, the identification device 321 is configured to issue a gear position signal SG1 based on the characteristic distance D1. For example, the power device 32 includes a control circuit (e.g., an integrated circuit board) and a power supply. The control circuit is configured to receive the gear position signal SG1 and, based on the gear position signal SG1, identify the connected actuator assembly SU as a first model actuator assembly, thereby controlling the circuit to perform an operation corresponding to the first model actuator assembly.

[0050] For example, Figure 8As shown, the connecting head 21 of the actuator assembly has a characteristic length D2, which is different from the characteristic length D1. Therefore, after the actuator assembly SU is connected to the tube assembly 10, the connecting head 21 pushes the identification mating portion 322 by the characteristic distance D2 via the first transmission assembly 10A and the second transmission assembly 33. At this time, the identification device 321 is configured to issue a gear position signal SG2 based on the characteristic distance D2. For example, the control circuit is configured to receive the gear position signal SG2 and, based on the gear position signal SG2, identify that the connected actuator assembly SU is an actuator assembly of the second model, thereby controlling the circuit to perform an operation corresponding to the actuator assembly of the second model.

[0051] For example, Figure 9 As shown, the connecting head 21 of the actuator assembly has a characteristic length D3, which is different from the characteristic length D1 and the characteristic length D2. Therefore, after the actuator assembly SU is connected to the tube assembly 10, the connecting head 21 pushes the identification mating portion 322 by the characteristic distance D3 through the first transmission assembly 10A and the second transmission assembly 33. At this time, the identification device 321 is configured to issue a gear position signal SG3 based on the characteristic distance D3. For example, the control circuit is configured to receive the gear position signal SG3 and, based on the gear position signal SG3, identify that the connected actuator assembly SU is a third model actuator assembly, thereby controlling the circuit to perform an operation corresponding to the third model actuator assembly.

[0052] Therefore, in the above embodiment, the identification device 321 has three gears corresponding to three characteristic lengths, so that the identification device 321 can automatically identify three types of actuator assemblies. At this time, the control circuit can control the device to complete the cutting process of the corresponding stroke, adapt to different surgical scenarios, and save medical costs; for example, in other embodiments, the identification device 321 may also have more or fewer gears, which can be set according to needs, and the embodiments of the present disclosure do not specifically limit this.

[0053] For example, in some embodiments, Figure 1 As shown, the actuator assembly SU includes an actuator 20 (also known as the actuator module) and a tubular body 40. The connecting head 21 is located on the tubular body 40. The entire actuator assembly SU can be disposable and replaced with each procedure. Because the actuator assembly SU needs to penetrate or contact patient tissue during surgery, a disposable actuator assembly SU is safer and more hygienic for the patient. For example, the tubular body assembly 10 can be reusable, so only the actuator assembly SU needs to be replaced between surgeries, thereby saving costs.

[0054] For example, in some embodiments, the medical device may be a stapler, such as a laparoscopic stapler. In this case, the actuator assembly SU includes a jaw assembly (i.e., the actuator module described above), which includes a first jaw and a second jaw that can be controlled to open or close. For example, one of the first jaw and the second jaw may contain a staple cartridge, and the other may contain an anvil capable of deforming staples ejected from the cartridge. For example, in other embodiments, the medical device may be another suitable medical device, such as a clip applier. The embodiments of the present disclosure do not specifically limit the type of medical device.

[0055] For example, in the case where the medical device is a stapler, the above-mentioned first model, second model and third model actuator assemblies can be, for example, actuator assemblies with staple line lengths of 30 mm, 45 mm and 60 mm respectively, and the control circuit can identify which model of actuator assembly is connected to the tube body assembly 10, and then control the actuator 20 to perform different operations according to the staple line lengths corresponding to different actuator assemblies.

[0056] For example, in some embodiments, the housing 31 may be a detachable housing, such as Figure 2 As described, the housing 31 may include a first sub-housing 31A and a second sub-housing 31B; the first sub-housing 31A is configured to be connected to the tube body assembly 10, and the second sub-housing 31B is arranged at the proximal end of the first sub-housing 31A and is connected to the first sub-housing 31A to be closed with the first sub-housing 31A to form a cavity, such as a sealed cavity, thereby isolating the power device 32 arranged in the cavity from the external environment, thereby preventing bacteria present on the reusable power device 32 from contaminating the external environment.

[0057] For example, in some embodiments, the second sub-housing 31B is rotatably connected to the first sub-housing 31A. Figure 2 As shown, the second sub-housing 31B is hinged to one end of the first sub-housing 31A, such as the top, through a hinge 31C (such as a rotating shaft), so that the second sub-housing 31B and the first sub-housing 31A can be opened and closed by the hinge 31C to facilitate the assembly of the power element 32.

[0058] For example, in some embodiments, the first sub-housing 31A and the second sub-housing 31B are detachably fixedly connected via a snap-fit ​​member 31D and a bottom snap-fit ​​member (not shown). For example, during installation, the second sub-housing 31B and the first sub-housing 31A are opened by relative rotation via the hinge 31C, and the power device 32 is then inserted. The second sub-housing 31B and the first sub-housing 31A are then closed by relative rotation via the hinge 31C, and the snap-fit ​​member 31D is snap-fitted to secure the power device 32, thereby sealing the power device 32 within the cavity of the housing 31.

[0059] For example, in some embodiments, the shell 31 can be a disposable shell, such as a transparent plastic shell. The disposable shell is in a sterile environment before use, such as in a sterile package. Therefore, the disposable shell can be replaced each time the device is operated to ensure that the handle part 30 is in a sterile state during use, and will not contaminate the operating environment and the operator's hands, etc., making it safer and more convenient to use.

[0060] For example, Figure 10 Schematic diagram showing the connection between the second transmission assembly and the identification matching portion. In some embodiments, such as Figure 10 As shown, the second transmission component 33 includes a slidable first push block 331, for example, the first push block 331 abutting against the first transmission component 10A (in some examples, it can also be called a shell push block), and the identification matching part 322 includes a second push block 332A abutting against the first push block 331 (in some examples, it can also be called a gear push block), that is, the identification matching part 322 is implemented in the form of a second push block, and the second push block 332A can be pushed by the first push block 331 to realize different gears of the identification device 321.

[0061] For example, in other embodiments, the identification matching part may also adopt other transmission structures other than the push block, such as a push rod, etc. The identification matching part may be an integrated structure, or it may include multiple interconnected sub-transmission structures, such as multiple sub-push blocks. The embodiments of the present disclosure do not specifically limit this.

[0062] For example, in some embodiments, Figure 10 As shown, the first push block 331 includes a push block body 331A and a proximal push rod 331B extending from the push block body 331A toward the second push block 332A. The handle assembly 30 also includes a bacteria isolation plate 34 disposed at the distal end of the housing 31, for example, Figure 11 Shows a partial structural diagram of the housing, combined with Figure 10 and Figure 11 The bacteria isolation plate 34 is arranged on the proximal side of the push block body 331A, that is, the bacteria isolation plate 34 is arranged on the side of the push block body 331A away from the tube body assembly 10, and is configured to separate the push block body 331A from the cavity and the power device 32. The bacteria isolation plate 34 includes a push rod through hole 341, and the proximal push rod 331B passes through the push rod through hole 341 and abuts against the second push block 332A to apply a pushing force to the second push block 332A.

[0063] For example, in some embodiments, when the housing 31 includes a first sub-housing 31A and a second sub-housing 31B, the first push block 331 and the bacteria isolation plate 34 are arranged in the first sub-housing 31A, so that the bacteria isolation plate 34 separates the components located at the far end of the first sub-housing 31A from the power device 32.

[0064] For example, Figure 12A schematic structural diagram of the first sub-housing 31A is shown. Figure 10 and Figure 12 As shown, the first push block 331 and the isolation plate 34 are disposed in the first sub-housing 31A. For example, the first push block 331 further includes a first elastic connector 35. One end of the first elastic connector 35 is connected to the side of the push block body 331A facing the isolation plate 34, and the other end of the first elastic connector 35 is connected to the isolation plate 34. For example, the end of the first elastic connector 35 away from the push block body 331A abuts the isolation plate 34, thereby achieving an elastic connection between the first push block 331 and the isolation plate 34. When the first push block 331 is pushed, the first elastic connector 35 can provide a certain buffering effect, making the pushing process smoother and improving the operator's experience. When the actuator assembly SU is disassembled, the first elastic connector 35 facilitates the distal reset of the first push block 331.

[0065] For example, in some embodiments, Figure 12 As shown, the first elastic connector 35 includes a first spring. A protruding spring connection portion 341 is provided on the side of the bacteria isolation plate 34 facing the push block body 331A. One end of the first spring is fixed to the push block body 331A, and the other end is sleeved on the spring connection portion 341. In other words, the portion of the first spring near the bacteria isolation plate 34 is sleeved on the spring connection portion 341. This helps to stabilize the first elastic connector 35 and prevents it from deflecting during elastic deformation, thereby improving the safety of the device.

[0066] For example, in some embodiments, the proximal push rod 331B is sealedly connected to the push rod through hole 341. For example, a seal, such as a rubber ring, is provided between the proximal push rod 331B and the push rod through hole 341 to seal the gap between the proximal push rod 331B and the push rod through hole 341 to ensure the bacteria isolation effect of the bacteria isolation plate 34.

[0067] For example, in an embodiment of the present disclosure, the proximal push rod 331B abuts against the second push block 332A, and the abutting connection method facilitates the assembly of the power device 32 and the shell 31. For example, after the power device 32 is installed in the cavity of the shell 31 and the first sub-shell 31A and the second sub-shell 31B are closed, the proximal push rod 331B and the second push block 332A can abut against each other. After the first sub-shell 31A and the second sub-shell 31B are opened, the proximal push rod 331B and the second push block 332A can be disconnected without the need for additional operation, thereby facilitating the installation and disassembly of the device and improving the efficiency and user experience of the device.

[0068] For example, in some embodiments, Figure 5As shown, the identification device 321 includes a sliding rheostat S, which includes a sliding portion S1 for adjusting resistance. A second push block 332A is connected to the sliding portion S1, and the sliding portion S1 is configured to move a characteristic distance to set a corresponding resistance. For example, the second push block 332A can push the sliding portion S1. When the sliding portion S1 is pushed, the sliding rheostat S has a different resistance, thereby allowing the identification device 321 to emit different identification signals, such as electrical signals of different intensities, for recognition by the control circuit.

[0069] For example, in some examples, such as Figure 5 As shown, the sliding rheostat S may further include a slide rail S2, with the second push block 332A slidably connected to the slide rail S2. Thus, the slide rail S2 defines the movement trajectory of the second push block 332A. For example, the second push block 332A may include a snap-fit ​​structure 322A, with the sliding portion S1 snapped to the snap-fit ​​structure 322A. Thus, the second push block 332A may drive the sliding portion S1 to reciprocate along the slide rail S2, thereby enabling the sliding rheostat S to be set to different resistances for easier gear position identification.

[0070] For example, in other embodiments, the identification device 321 may also be other forms of sensor devices that can generate different signals according to the pushing distance, such as a pressure sensor, a photoelectric sensor, etc. The embodiments of the present disclosure do not limit the specific implementation form of the identification device 321.

[0071] For example, in some embodiments, Figure 5 As shown, the identification and mating portion further includes a second spring connector 323, which is disposed on a side of the second push block 332A away from the first push block 331. The end of the second spring connector 323, away from the first push block 331, can be fixed to a fixed member (not shown) in the power unit 32, thereby elastically connecting the second push block 332A to the power unit 32. As a result, when the second push block 332A is pushed, the second spring connector 323 acts as a buffer, facilitating a smooth pushing process. Furthermore, when the actuator assembly SU is removed, the second spring connector 323 can also facilitate the reset of the second push block 332A. With the reset of the second push block 332A and the first elastic connector 35, the medical device's model identification function remains effective when a new actuator assembly SU is installed after the actuator assembly SU is removed. For example, the fixed member in the power unit 32 can be a baffle or other suitable fixing structure within the power unit 32, which is not specifically limited in the embodiments of the present disclosure.

[0072] For example, in some embodiments, Figure 1As shown, the proximal end of the tube body assembly 10 includes a rotation control portion 50. After the tube body assembly 10 is connected to the handle assembly 30, the rotation control portion 50 can rotate relative to the handle assembly 30, and then the actuator assembly SU rotates accordingly, thereby flexibly controlling the operating angle of the actuator assembly SU.

[0073] For example, in some embodiments, Figure 3 As shown, the first transmission assembly 10A includes a push rod 11 and a proximal end of the push rod 11 ( Figure 3 The right end of the rotating push member 12, Figure 13 A schematic diagram showing the connection between the pushing connecting rod 11 and the rotating pushing member 12 is shown. Figure 14 FIG. 1 shows a schematic diagram of the push connecting rod 11 and the rotating push member 12 in a state to be connected, as shown in FIG. Figure 13 and Figure 14 As shown, the rotating pushing member 12 includes a proximal end ( Figure 3 The push link 11 and the rotational connection portion 12A (right end in FIG) and the linear push portion 12B abutting against the first push block 331 are now in contact with the handle assembly. As a result, the push link 11 and the rotational connection portion 12A can rotate relative to each other, facilitating rotation of the rotation control portion 50 relative to the handle assembly 30.

[0074] For example, the linear pushing portion 12B and the first pushing block 331 are connected in an abutting manner, which helps to assemble the tube body assembly 10 and the outer shell 31 of the handle assembly 30. For example, when the tube body assembly 10 and the outer shell 31 of the handle assembly 30 are installed, the linear pushing portion 12B and the first pushing block 331 can be abutted. When the tube body assembly 10 and the outer shell 31 of the handle assembly 30 are disassembled, the linear pushing portion 12B and the first pushing block 331 can be disconnected without the need for additional operations, thereby simplifying the assembly process.

[0075] For example, Figure 13 and Figure 14 As shown, the proximal end of the push rod 11 ( Figure 3 The right end of the handle assembly 30 (see FIG. 1 ) has a rotating connection structure 11A. The rotating connection structure 11A includes an annular groove 111 that cooperates with the rotating connection portion 12A. The rotating connection portion 12A can be inserted into the annular groove 111. After the rotating connection portion 12A is inserted into the annular groove 111, the rotating connection structure 11A and the rotating connection portion 12A can rotate relative to each other. Therefore, when the rotation control portion 50 rotates relative to the handle assembly 30, the rotating connection structure 11A rotates relative to the rotating connection portion 12A. At this time, the rotating push member 12 can maintain its original shape without rotating and always abut against the first push block 331, so that the rotating push member 12 abuts against the second transmission assembly 33, ensuring that the actuator assembly SU model recognition function is normal.

[0076] For example, in some embodiments, Figure 13 and Figure 14 As shown, the linear pushing portion 12B extends along the axial direction of the tube assembly, the rotating connecting portion 12A is semi-annular, and the linear pushing portion 12B is strip-shaped. The extension direction of the linear pushing portion 12B is perpendicular to the plane where the rotating connecting portion 12A is located. That is, the angle a between the linear pushing portion 12B and the rotating connecting portion 12A is 90 degrees. This facilitates the simultaneous realization of rotating and pushing operations.

[0077] For example, in some embodiments, Figure 3 As shown, the first transmission assembly 10A may further include a distal end ( Figure 3 The third push block 13 (left end in FIG) can also be called a connecting rod push block. After the actuator assembly SU is installed on the sleeve assembly 10, the connecting head 21 of the actuator assembly SU abuts against the pushing connecting rod 11, so that the connecting head 21 transmits the pushing force through the third push block 13, the pushing connecting rod 11 and the rotating pushing member 12 in sequence.

[0078] For example, in other embodiments, the first transmission assembly 10A may also include more or fewer transmission components, as long as the transmission of the pushing force can be achieved.

[0079] For example, in an embodiment of the present disclosure, the connecting head 21 and the pushing link 11 are connected in an abutting manner to facilitate the assembly between the actuator assembly SU and the tube body assembly 10. For example, when the actuator assembly SU and the tube body assembly 10 are installed, the connecting head 21 and the pushing link 11 can be abutted. When the actuator assembly SU and the tube body assembly 10 are disassembled, the connecting head 21 and the pushing link 11 can be disconnected without the need for additional operations, thereby making the assembly process of the device simpler and improving the efficiency and user experience of the device.

[0080] For example, Figure 15 A schematic structural diagram of the tube body assembly is shown. In some embodiments, the proximal end of the tube body assembly 10, such as the proximal end of the rotation control portion 50, has a push block groove 14. The push block groove 14 is adapted to the first push block 331. The distal end 331E of the first push block 331 is accommodated and abutted in the push block groove 14. The linear push portion 12B can abut against the distal end 331E of the first push block 331 at the groove 14. For example, the distal end 331E of the first push block 331 is in the form of a convex shape, and the convex shape matches the push block groove 14. This is beneficial to the precise connection between the shell 31 and the tube body assembly 10, and is beneficial to the accurate abutment between the first push block 331 and the rotating push member 12. For example, after the tube body assembly 10 is connected to the handle assembly 30, the first push block 331 can abut against the rotating push member 12. In addition, as Figure 15As shown, the linear push portion 12B is arranged at the distal end of the push block groove 14. When the tube assembly is not installed, the rotation control portion 50 can protect the linear push portion 12B from being deformed and damaged by external collision. Figure 12 As shown, the distal end 331E of the first pushing block 331 does not exceed the distal end of the first sub-housing 31A, and thus the first pushing block 331 is also less likely to be deformed and damaged by external impact.

[0081] For example, Figure 16 The schematic diagram of the structure of the casing core 16 of the pipe body assembly is shown. In some embodiments, as shown in FIG. Figure 16 As shown, the inner core 16 of the sleeve is arranged at the distal end of the inner portion of the pipe body assembly 10, and the inner core 16 of the sleeve includes a first matching portion 15. Figure 6-Figure 9 The proximal end of the actuator assembly SU includes a second mating portion 22. When the tube body assembly 10 and the actuator assembly SU are installed, the second mating portion 22 is mated and connected with the first mating portion 15, which is conducive to the precise connection between the tube body assembly 10 and the actuator assembly SU. At the same time, it also avoids the connection of an unmatched actuator assembly SU to the tube body assembly 10 provided in the embodiment of the present disclosure, thereby avoiding misuse of the actuator assembly SU and improving the safety of the device.

[0082] For example, in some examples, one of the first mating portion 15 and the second mating portion 22 is a protrusion and the other is a groove, and the shapes of the protrusion and the groove match to achieve precise connection. Figure 16 In the illustrated embodiment, the first mating portion 15 is a protrusion, and the second mating portion 22 is a groove; for example, in other embodiments, the first mating portion 15 may be a groove, and the second mating portion 22 may be a protrusion, and the embodiments of the present disclosure do not specifically limit this.

[0083] For example, when the handle assembly, tube body assembly and actuator assembly provided in the embodiment of the present disclosure are assembled, the actuator assembly is detachably connected to the distal end of the tube body assembly, the distal end of the third push block abuts against the connecting head, and the handle assembly is detachably connected to the proximal end of the tube body assembly. Thus, the connecting head pushes the identification mating part a characteristic distance through the first transmission assembly and the second transmission assembly, and the characteristic distance corresponds to the characteristic length.

[0084] In summary, in the medical device provided by the embodiment of the present disclosure, the identification device can send corresponding gear signals according to the characteristic lengths of the connecting heads of different actuator assemblies, and then the control circuit of the device can perform operations on the actuator assembly according to the gear signal, thereby realizing automatic identification of different actuator assemblies, and realizing the connection of the same operating handle to and control of different actuator assemblies to perform corresponding operations; in addition, the medical device includes a plurality of transmission assemblies, which are respectively arranged in different structures and connected and matched, such as abutment matching, to facilitate the disassembly and connection between different structures, and are particularly suitable for when each component is reused or disposable, such as a reusable tube body assembly, a disposable shell and a reusable The disassembly and connection between the power devices used expands the scope of application, improves the efficiency and experience of use; in addition, the first transmission assembly also has a rotating structure (rotating connection part 12A) to cooperate with the rotation operation of the rotation control part, so that the model identification function of the actuator assembly is compatible with the circumferential rotation function of the medical device, thereby improving the flexibility of use of the device; in addition, the medical device also includes a replaceable disposable shell, and a transmission assembly is designed on the shell, so that on the basis of having an automatic identification function, it also ensures the sterility of the device during use, thereby improving the safety of use of the device; the reset function of the second push block and the first elastic connector can ensure that after the actuator assembly is replaced, the medical device still has the actuator assembly model identification function.
