[0054] In order to illustrate the technical solutions of the present application, the following will be described in combination with specific drawings and embodiments.

[0055] In the traditional anastomat, the cutting knife is mainly retracted by the pull rod, that is, when the cutting knife needs to be retracted, the user needs to manually pull the pull rod to make the cutting knife retract, which is time-consuming and laborious and inconvenient to operate.

[0056] In order to solve the above problems, the anastomat handle component and the anastomat provided by the embodiments of the present application can make the cutting knife retracting process time-saving and labor-saving and convenient to operate.

[0057] Please refer to Figures 1 to 6 , Figure 1 is a structural schematic diagram of an anastomat handle component 100 in one embodiment of the present application, Figure 2 is Figure 1 is an exploded structural diagram of the anastomat handle component 100 shown in Figure 3 is Figure 2 is a local enlarged view of the A part of the anastomat handle component 100 shown in Figure 4 is Figure 1 is a sectional view of the anastomat handle component 100 along the M-M direction shown in Figure 5 is Figure 1 is a structural schematic diagram of the internal structure of the anastomat handle component 100 shown in Figure 6 is Figure 5 is a structural schematic diagram of the internal structure of the anastomat handle component 100 from another perspective shown in

[0058] In a first aspect, an embodiment of the present application provides an anastomat handle component 100, comprising a housing 10, a first moving piece 20, a second moving piece 30, a synchronous transmission piece 40, a trigger assembly 50 and an adjusting assembly 60. Wherein, the first moving piece 20 is movably arranged in the housing 10; the second moving piece 30 is movably arranged in the housing 10, one of the first moving piece 20 and the second moving piece 30 is used to be connected with a cutting knife (not shown in the figure).

[0059] In this embodiment, the first moving piece 20 is connected with the cutting knife.

[0060] The first moving piece 20 and the second moving piece 30 are both in transmission connection with the synchronous transmission piece 40, so that the first moving piece 20 and the second moving piece 30 move synchronously, and the moving directions of the first moving piece 20 and the second moving piece 30 are opposite; the trigger assembly 50 is in transmission connection with the first moving piece 20, so as to drive the first moving piece 20 to move along a first direction, and the first direction is a direction from a proximal end of the first moving piece 20 to a distal end of the first moving piece 20.

[0061] It can be understood that, since the first moving piece 20 and the second moving piece 30 are both in transmission connection with the synchronous transmission piece 40, so that the first moving piece 20 and the second moving piece 30 move synchronously, and the moving directions of the first moving piece 20 and the second moving piece 30 are opposite, when the trigger assembly 50 drives the first moving piece 20 to move along the first direction, the second moving piece 30 will synchronously move along a second direction, and the second direction is a reverse direction opposite to the first direction. For example, in Figure 4 , the first direction is a direction indicated by an arrow J, and the second direction is a direction indicated by an arrow K.

[0062] The adjusting component 60 is connected to the second moving part 30. The adjusting component 60 can drive the second moving part 30 to move closer to the trigger assembly 50, so that the trigger assembly 50 is connected to the second moving part 30 in a transmission manner, and at the same time, the trigger assembly 50 is disconnected from the first moving part 20.

[0063] Understandably, since the adjusting component 60 can move the second moving member 30 closer to the trigger assembly 50, the second moving member 30 is closer to the trigger assembly 50, thereby enabling the trigger assembly 50 to be connected to the second moving member 30 in a transmission manner, and simultaneously disengaging the trigger assembly 50 from the first moving member 20. The adjusting component 60 can also move the second moving member 30 away from the trigger assembly 50, thereby disengaging the trigger assembly 50 from the second moving member 30, and simultaneously reconnecting the trigger assembly 50 to the first moving member 20 in a transmission manner.

[0064] Please refer to this as well. Figure 7 , Figure 8 and Figure 9 , Figure 7 It is Figure 5 The diagram shows the first moving member 20 of the stapler handle assembly 100 after it has moved along a first direction. Figure 8 It is Figure 4 The diagram shows the first moving member 20 of the stapler handle assembly 100 after it has moved along a first direction. Figure 9 It is Figure 7 A schematic diagram of the second moving part 30 of the stapler handle assembly 100 after it has moved toward the trigger assembly 50.

[0065] In this embodiment, when advancing the cutting blade, the trigger assembly 50 can drive the first moving member 20 connected to the cutting blade to move along the first direction, and drive the second moving member 30 to move in the opposite direction to the first direction, thereby advancing the cutting blade. When it is necessary to retract the cutting blade, the adjustment assembly 60 can be used to drive the second moving member 30 to move closer to the trigger assembly 50, so that the trigger assembly 50 and the second moving member 30 are connected in a transmission manner, and at the same time, the trigger assembly 50 is disconnected from the first moving member 20. The trigger assembly 50 can then drive the second moving member 30 to move along the first direction, and drive the first moving member 20 to move in the opposite direction to the first direction.

[0066] It can be understood that in other embodiments, if the second moving part 30 is connected with the cutting knife, when the advancement of the cutting knife is realized, only the second moving part 30 is moved to the direction close to the trigger assembly 50 by the adjusting assembly 60, so that the trigger assembly 50 is in transmission connection with the second moving part 30, and at the same time, the trigger assembly 50 is disconnected with the first moving part 20, and the second moving part 30 can be driven to move in the first direction by the trigger assembly 50, and the first moving part 20 is driven to move in the direction opposite to the first direction; when the retreat of the cutting knife is realized, only the second moving part 30 is moved to the direction away from the trigger assembly 50 (ultimately limited by the shell 10) by the adjusting assembly 60, so that the trigger assembly 50 is disconnected with the second moving part 30, and at the same time, the trigger assembly 50 is in transmission connection with the first moving part 20, and the first moving part 20 can be driven to move in the first direction by the trigger assembly 50, and the second moving part 30 is driven to move in the second direction.

[0067] It should be noted that the adjusting assembly 60 can be a gas cylinder, a hydraulic cylinder or a linear module.

[0068] The handle component 100 provided by the embodiment of the present application, since the first moving part 20 and the second moving part 30 are movably arranged in the shell 10, one of the first moving part 20 and the second moving part 30 is used to be connected with the cutting knife, and the first moving part 20 and the second moving part 30 are in transmission connection with the synchronous transmission part 40, so that the first moving part 20 and the second moving part 30 move synchronously, and the moving directions of the first moving part 20 and the second moving part 30 are opposite, the trigger assembly 50 is in transmission connection with the first moving part 20, the adjusting assembly 60 is connected with the second moving part 30, and the adjusting assembly 60 can drive the second moving part 30 to move to the direction close to the trigger assembly 50, so that the trigger assembly 50 is in transmission connection with the second moving part 30, and at the same time, the trigger assembly 50 is disconnected with the first moving part 20, therefore, when the advancement and retreat of the cutting knife is switched, only the position of the second moving part 30 is adjusted by the adjusting assembly 60, so that one of the first moving part 20 and the second moving part 30 is in transmission connection with the trigger assembly 50, and the other of the first moving part 20 and the second moving part 30 is disconnected with the trigger assembly 50, that is, the handle component provided by the embodiment of the present application can be driven by the trigger assembly 50 when the advancement and retreat of the cutting knife is realized, and the operator can operate by one hand, which is simple and convenient, and saves time and effort.

[0069] Please refer to Figure 10 , Figure 10 is Figure 2 the structural schematic view of the first moving part 20, the second moving part 30 and the adjusting assembly 60 shown in the figure.

[0070] Optionally, the first moving member 20 is provided with a first synchronization gear set 21, the second moving member 30 is provided with a second synchronization gear set 31, the synchronization transmission member 40 is provided with a synchronization gear 41, and the first synchronization gear set 21 and the second synchronization gear set 31 are driven by the synchronization gear 41. In this way, the first moving member 20 and the second moving member 30 can be driven to move in opposite directions synchronously.

[0071] Specifically, the first moving member 20 and the second moving member 30 can be provided as a rack or the like having a gear set and capable of being driven by the synchronization gear 41 of the synchronization transmission member 40.

[0072] In the embodiment, the synchronization transmission member 40 includes a synchronization gear between the first moving member 20 and the second moving member 30, and the synchronization gear 41 is arranged on the synchronization gear. In this way, the structure of the synchronization transmission member 40 can be simple, and the first moving member 20 and the second moving member 30 can be driven to move in opposite directions synchronously.

[0073] It can be understood that the synchronization gear is rotatably arranged in the housing 10.

[0074] In other embodiments, the synchronization transmission member 40 includes at least two synchronization pulleys (not shown in the figure) and a synchronization belt (not shown in the figure) wound around the synchronization pulleys, the first moving member 20 and the second moving member 30 are arranged on two sides of the synchronization belt respectively, and the synchronization gear 41 is arranged on the synchronization belt. In this way, the first moving member 20 and the second moving member 30 can be driven to move in opposite directions synchronously.

[0075] Please refer to Figure 11 , Figure 11 is Figure 2 the exploded view of the trigger assembly 50 shown in FIG. 1.

[0076] Optionally, the first moving member 20 is provided with a first driving gear set 22, the second moving member 30 is provided with a second driving gear set 32, and the trigger assembly 50 includes a power driving member 51, which is in driving connection with the first driving gear set 22 or the second driving gear set 32.

[0077] By using the above scheme, the power driving member 51 can drive the first moving member 20 and the second moving member 30 to move in the first direction.

[0078] Specifically, the first driving gear set 22 includes a plurality of first ratchets (not shown in the figure), and the power driving member 51 includes a driving pawl matched with the first ratchets. In this way, the driving pawl can be matched with different first ratchets in sequence to drive the first moving member 20 to move in the first direction.

[0079] Similarly, the second driving tooth set 32 comprises a plurality of second ratchets (not shown in the figure), which are matched with the driving pawl. In this way, the second moving part 30 can be driven to move in the first direction by matching the driving pawl with different second ratchets in sequence.

[0080] In the embodiment, the trigger assembly 50 further comprises a trigger 52, a driving elastic member 53, a reset elastic member 54, and a connecting pin 55. The trigger 52 is rotatably connected to the housing 10 through the connecting pin 55. The driving pawl is arranged on the trigger 52. The driving elastic member 53 abuts against the driving pawl, so that the driving pawl rotates relative to the trigger 52 to be in transmission connection with the first moving part 20. The reset elastic member 54 is connected to the trigger 52, so that the trigger 52 rotates relative to the housing 10 and the driving pawl moves in the second direction. The driving elastic member 53 and the reset elastic member 54 can both be torsional springs.

[0081] When the trigger 52 is released after being pulled to the bottom, the trigger 52 is automatically reset under the action of the reset elastic member 54. The driving pawl automatically moves below the first ratchet under the action of the driving elastic member 53 of the trigger 52, and retreats to the proximal end, preparing for the next firing. Finally, the cutting knife at the jaw of the stapler is limited at the distal end, and thus the trigger 52 at the handle end cannot be pulled.

[0082] Please refer to Figure 2 、 Figure 3 and Figure 10 Optionally, the handle component further comprises a slide rail member 70 connected to the adjusting assembly 60. The slide rail member 70 is movably arranged in the housing 10. The moving direction of the slide rail member 70 is arranged at an angle to the moving direction of the first moving part 20. The second moving part 30 is slidably connected to the slide rail member 70.

[0083] By adopting the above scheme, the second moving part 30 can move in the first direction and the second direction, and the adjusting assembly 60 can drive the second moving part 30 to move towards the trigger assembly 50.

[0084] It can be understood that the moving direction of the slide rail member 70 is the direction towards the trigger assembly 50, that is, the adjusting assembly 60 can drive the slide rail member 70 and the second moving part 30 to move towards the trigger assembly 50 together, and the second moving part 30 can move in the first direction and the second direction relative to the slide rail member 70.

[0085] Specifically, the slide rail piece 70 comprises a first part 71 and a second part 72 connected with each other, the adjusting assembly 60 is connected with the first part 71, the second part 72 is provided with a dovetail groove 721, the length direction of the dovetail groove 721 is parallel to the first direction, the second moving piece 30 is provided with a protrusion 33 matched with the dovetail groove 721, the protrusion 33 realizes the sliding connection between the second moving piece 30 and the slide rail piece 70 by matching with the dovetail groove 721. In this way, the second moving piece 30 can move in the first direction and the second direction, and the adjusting assembly 60 can drive the second moving piece 30 to move towards the trigger assembly 50, and the second moving piece 30 is prevented from being disconnected with the slide rail piece 70.

[0086] Please refer to Figure 2 and Figure 10 Optionally, the adjusting assembly 60 comprises an adjusting transmission piece 61 and an adjusting driving piece 62, the adjusting transmission piece 61 is movably connected with the housing 10, one end of the adjusting transmission piece 61 is connected with the adjusting driving piece 62, and one end is connected with the slide rail piece 70, the slide rail piece 70 is controlled to move by driving the adjusting driving piece 62, so that the second moving piece 30 is in transmission connection with the trigger assembly 50.

[0087] By adopting the above scheme, the adjusting driving piece 62 can be driven to control the slide rail piece 70 and the second moving piece 30 to move towards the trigger assembly 50, so that the second moving piece 30 is in transmission connection with the trigger assembly 50.

[0088] The adjusting driving piece 62 can be a knob, and the operator can use the index finger to control the slide rail piece 70 to move by rotating the adjusting driving piece 62, so that the second moving piece 30 is in transmission connection with the trigger assembly 50.

[0089] Specifically, the adjusting transmission piece 61 is rotationally connected with the housing 10, and the adjusting transmission piece 61 is rotationally connected with the slide rail piece 70 and is in threaded connection with the slide rail piece 70. In this way, the structure of the adjusting assembly 60 is relatively simple, and the slide rail piece 70 can be controlled to move by rotating the adjusting transmission piece 61, so that the second moving piece 30 is in transmission connection with the trigger assembly 50.

[0090] The adjusting transmission piece 61 can be a stud or a lead screw. The adjusting transmission piece 61 can be rotationally connected with the housing 10 through a bearing 63, or a hole is arranged in the housing 10, and the adjusting transmission piece 61 is rotationally arranged in the hole.
