Description

Technical Field

[0001] This utility model relates to the field of medical devices, and more specifically to a stapler handle, a stapler handle housing assembly, and a stapler. Background Technology

[0002] In surgical treatment, various staplers are widely used, such as skin staplers, digestive tract staplers (esophagus, gastrointestinal tract, etc.), and laparoscopic staplers. These staplers are medical devices that replace traditional manual suturing. Due to the development of modern technology and improvements in manufacturing techniques, the various staplers currently used in clinical practice have advantages such as fast and accurate suturing, simple operation, less bleeding, and few side effects and surgical complications. They can be used to remove lesions and are therefore widely used both domestically and internationally.

[0003] Currently, some anastomotic devices include a cutting section with an anvil, staple cartridge, and actuator, as well as a drive unit to drive the actuator. The electric drive unit consists of a power supply, a control board, a closing drive unit, and a firing drive unit. The closing drive unit consists of a closing motor and a closing transmission mechanism. The input end of the closing transmission mechanism is connected to the closing motor, and the output end is connected to the actuator of the cutting section. The firing drive unit consists of a firing generator and a firing transmission mechanism. The input end of the firing transmission mechanism is connected to the firing generator, and the output end is connected to the actuator of the cutting section. Both the closing motor and the firing generator are connected to the control board via wires, and the control board is connected to the power supply via wires. The operating handle is equipped with operating buttons and a selector switch. The selector switch is connected to the control board via wires. The operating buttons consist of a forward button and a reverse button mounted on the control board. Pressing the forward button controls the firing generator and the firing transmission mechanism, while pressing the forward and reverse buttons controls the operation of the closing drive unit and the firing drive unit, respectively.

[0004] The forward and reverse buttons are two separate buttons spaced apart on the stapler handle. During surgery, their operation is not sensitive enough and is uncomfortable. Even with a disposable protective cover over the handle for reuse, the forward and reverse buttons become even less sensitive when pressed by the surgeon or other operators. Furthermore, factors such as tilting the button, applying excessive force, or slippage can lead to simultaneous pressing and misoperation. Utility Model Content

[0005] At least one embodiment of this utility model provides a stapler handle, the stapler handle comprising: a handle body, a button, and a motor. The button is disposed on the handle body and at least partially protrudes from the surface of the handle body, the button having an integrated structure and including a first button protrusion and a second button protrusion; the motor is disposed within the stapler handle, the motor including a motor shaft; the button is configured to: activate the first button protrusion to drive the motor shaft to rotate in a first direction, and activate the second button protrusion to drive the motor shaft to rotate in a second direction, the first direction being opposite to the second direction.

[0006] For example, in the anastomosis device handle structure provided in at least one embodiment of the present invention, the button has a first working surface protruding from the handle body, the first working surface has a first end and a second end and a first flat portion located between the first end and the second end, the first button protrusion is located at the first end of the first working surface and protrudes from the first flat portion, and the second button protrusion is located at the second end of the first working surface and protrudes from the first flat portion.

[0016] For example, in at least one embodiment of the present invention, the housing assembly further includes a button connection portion, which is connected to the housing button portion and the housing body respectively, and the housing button portion is movable relative to the housing body.

[0017] For example, in at least one embodiment of the present invention, the shell button portion and the button connecting portion are both made of flexible materials; or, the button connecting portion is made of flexible materials and the shell button portion is made of rigid materials.

[0018] For example, in at least one embodiment of the present invention, the shell body includes a first shell portion and a second shell portion, the first shell portion and the second shell portion are rotatably connected, and when the first shell portion and the second shell portion are closed, a cavity is formed inside to accommodate the stapler handle, and the shell button portion is disposed on the first shell portion.

[0036] At least one embodiment of this utility model provides a stapler handle, the stapler handle comprising: a handle body, a button, and a motor. The button is disposed on the handle body and at least partially protrudes from the surface of the handle body, the button having an integrated structure and including a first button protrusion and a second button protrusion; the motor is disposed within the stapler handle, the motor including a motor shaft; the button is configured to: activate the first button protrusion to drive the motor shaft to rotate in a first direction, and activate the second button protrusion to drive the motor shaft to rotate in a second direction, the first direction being opposite to the second direction.

[0037] At least one embodiment of the present invention also provides a housing assembly for a stapler handle, the housing assembly including a housing body and a housing button portion; the housing button portion is an integral structure, disposed on the housing body, protruding from the outer surface of the housing body, and includes a first housing button protrusion and a second housing button protrusion.

[0038] At least one embodiment of this utility model also provides a stapler, the stapler including any of the stapler handles provided in the embodiments of this utility model, the stapler further including a cutting device, a transmission assembly, and a jaw assembly, the jaw assembly being configured to open or close; the transmission assembly extending along the axial direction of the stapler, the proximal end of the transmission assembly being connected to the motor, and the distal end of the transmission assembly being connected to the cutting device and the jaw assembly; the motor shaft of the motor rotating along a second direction to drive the transmission assembly to move along the axial direction toward the distal end of the stapler, thereby driving the cutting device to move toward the distal end of the stapler and / or the jaw assembly to close; the motor shaft of the motor rotating along a first direction to drive the transmission assembly to move along the axial direction toward the proximal end of the stapler, thereby driving the cutting device to move toward the proximal end of the stapler and / or the jaw assembly to open.

[0039] For example, Figure 1 This is a schematic diagram of a stapler handle provided in one embodiment of the present invention; Figure 2 This is a schematic diagram showing the connection relationship of a portion of the structure of a stapler handle according to an embodiment of this utility model. (Reference) Figure 1-2 The stapler handle 100 includes a handle body 10, a motor 2, and a button 3 disposed on the handle body 10. The button 3 is an integral structure, at least partially protruding from the surface of the handle body 10, and includes a first button protrusion 31 and a second button protrusion 32. The motor 2 is located inside the stapler handle 10. The button 3 is configured to: activate (e.g., press or flick) the first button protrusion 31 to drive the motor shaft of the motor 2 to rotate in a first direction; and activate (e.g., press or flick) the second button protrusion 32 to drive the motor shaft of the motor 2 to rotate in a second direction, the first direction being opposite to the second direction. In the stapler, the stapler handle 100 serves as the power unit of the stapler and includes... Figure 2 The motor 2 and controller 5 shown provide driving power for the movement of various components of the stapler.

[0040] In the stapler handle 100 provided in the embodiments of this utility model, the first button protrusion 31 and the second button protrusion 32 are two protrusions located on the same integrally formed button 3, instead of two separate buttons set on the surface of the handle body 10. Therefore, when the operator (e.g., a doctor, stapler device tester, etc.) uses the stapler, the operator holds the handle body 10. For example, the doctor's attention and vision are focused on observing the target tissue of the surgical subject. The doctor's eyes do not need to look at the handle buttons; the fingers can easily locate the entire integrally formed button 3, and the first button protrusion 31 and the second button protrusion 32 can be felt by touch, allowing the first button protrusion 31 and the second button protrusion 32 to be pressed as needed. Compared to setting two separate, independent buttons on the surface of the handle body 10 to perform the functions of the first button protrusion 31 and the second button protrusion 32, the stapler handle 100 provided in the embodiments of this utility model allows the doctor to more quickly and accurately locate the positions of the first button protrusion 31 and the second button protrusion 32 during surgical operations, resulting in more sensitive and comfortable operation.

[0041] In addition, before using the stapler for surgical procedures, a sterile, disposable protective shell (such as the stapler handle shell assembly 200 described below) can be applied to the surface of the stapler handle 100. This avoids direct sterilization of the stapler handle 100, which could damage the components inside. The stapler handle 100 can be reused; for example, the disposable protective shell can be replaced the next time the stapler is used. In the stapler handle 100 provided in the embodiments of this utility model, since the one-piece molded button 3 protrudes from the surface of the handle body 10, and the first button protrusion 31 and the second button protrusion 32 are protrusions located on the one-piece molded button 3, even when covered by the protective shell, the first button protrusion 31 and the second button protrusion 32 can still be easily felt by the doctor's fingers by touch. This facilitates the use of the stapler by applying a sterile, disposable protective shell to the surface of the stapler handle 100.

[0042] For example, refer to Figure 1 Button 3 is located at the distal end of the handle body 10, i.e., on the surface of the distal end of the handle body 10, for easy operation by the operator. For example, when the operator holds the handle body 10 during use, the operator's index finger can press the first button protrusion 31 and the second button protrusion 32, or the index and middle fingers can press the first button protrusion 31 and the second button protrusion 32 respectively, making operation easy. Here, the distal end of the handle body 10 refers to the side of the handle body 10 facing the jaw assembly (described below) of the stapler containing the handle body 10. Of course, in other embodiments, button 3 may also be located at other positions on the handle body 10.

[0043] For example, refer to Figure 1 Button 3 has a first working surface S1 away from the handle body 10. The first working surface S1 has a first end and a second end opposite each other in the longitudinal direction D2, and a first flat portion S13 located between the first end and the second end. A first button protrusion 31 is located at the first end of the first working surface S1 and protrudes from the first flat portion S13. A second button protrusion 32 is located at the second end of the first working surface S1 and protrudes from the first flat portion S13. For example, the first working surface S1 also includes a first arcuate surface S11 and a second arcuate surface S12. The first arcuate surface S11 connects the first button protrusion 31 and the first flat portion S13, that is, the first arcuate surface S11 is the junction of the first button protrusion 31 and the first flat portion S13; the second arcuate surface S12 connects the second button protrusion 32 and the first flat portion S13, that is, the second arcuate surface S12 is the junction of the second button protrusion 32 and the first flat portion S13. For example, both the first arcuate surface S11 and the second arcuate surface S12 are concave surfaces. This design makes the feel more comfortable, and the first button protrusion 31 and the second button protrusion 32 are easier to perceive. For example, see reference. Figure 1 The handle body 10 extends longitudinally along D2, and the first button protrusion 31 and the second button protrusion 32 are arranged longitudinally along D2. For the sake of brevity and convenience in the following description, longitudinally refers to the extending direction of the handle body 10. The longitudinal direction intersects with the overall extending direction (i.e., axial direction) of the transmission assembly of the anastomosis device. "Intersection" includes, but is not limited to, perpendicularity. For example, in Figure 1 In the illustrated embodiment, the extension direction of the handle body 10 intersects the axial direction D1 but is not perpendicular to it. The handle body 10 has an upper part 10a (i.e., the upper end) and a lower part 10b (i.e., the lower end) that are opposite each other in the longitudinal direction D2. During use, the lower part 10b is closer to the ground than the upper part 10a. The first button protrusion 31 is located on the side of the second button protrusion 32 away from the lower part 10b of the handle body 10, and in the direction perpendicular to the first flat portion S13, the height of the first button protrusion 31 protruding from the first flat portion S13 is greater than the height of the second button protrusion 32 protruding from the first flat portion S13. During operation, the operator's fingers are responsible for pressing the first button protrusion 31 and the second button protrusion 32. Generally, pressing the upper button requires more effort than pressing the lower button. Therefore, the upper button protrusion is made more prominent, making it easier for the operator to press the upper button protrusion.

[0044] Of course, in other embodiments, it can also be arranged in a transverse direction that intersects (e.g., perpendicular to) the longitudinal direction D2.

[0045] Figure 3 This is a disassembled schematic diagram of a portion of the structure of a stapler handle according to an embodiment of the present invention; Figure 4This is a partial cross-sectional view of a stapler handle according to an embodiment of the present invention. For example, refer to... Figure 2-4 The stapler handle 100 also includes a controller 5, a first switch 41, and a second switch 42. The orthographic projection of button 3 on a plane parallel to the first flat portion S13 overlaps with the orthographic projections of the first switch 41 and the second switch 42 on the same plane. Motor 2, the first switch 41, and the second switch 42 are electrically connected to the controller 5. The button is configured to: press the first button protrusion 31 to activate the first switch 41, thereby driving the motor shaft of motor 2 to rotate in a first direction via the controller 5; and press the second button protrusion 32 to activate the second switch 42, thereby driving the motor shaft of motor 2 to rotate in a second direction via the controller 5, the second direction being the opposite of the first direction. In one embodiment, a switch seal 40 is fitted onto the first switch 41 and the second switch 42 and forms a sealed connection with the switch circuit board 43. The material of the switch seal 40 is, for example, rubber. The switch seal 40 helps prevent liquid from entering the stapler handle 100 through the connection between the first switch 41 and the second switch 42 and the handle body 10, thus preventing damage to its internal electrical components.

[0046] For example, refer to Figure 4 The handle body 10 also includes a connecting shaft 33. The button 3 is movably connected to the handle body 10 via the connecting shaft 33. Preferably, the first button protrusion 31 and the second button protrusion 32 are rotatably connected to the connecting shaft 33; for example, the first button protrusion 31 and the second button protrusion 32 are pivotally mounted on the connecting shaft 33. When the first button protrusion 31 is touched (e.g., pressed or tossed) to activate the first switch 41, the second button protrusion 32 moves away from the second switch 42. When the second button protrusion 32 is touched (e.g., pressed or tossed) to activate the second switch 42, the first button protrusion 31 moves away from the first switch 41. For example, the first switch 41 and the second switch 42 are disposed within the handle body 10 and electrically connected to the switch circuit board 43. Figure 2The switch circuit board 43 is electrically connected to the controller 5, thereby transmitting the start and stop signals of the first switch 41 and the second switch 42 to the controller 5, which then controls the operation of the motor 2. When the first button protrusion 31 is touched (e.g., pressed or tossed), the first contact position of the button 3 near the first switch 41, for example, the surface of the button 3 near the first switch 41, applies pressure to the first switch 41 to activate it. This causes the motor shaft of the motor 2 to rotate in a first direction via the controller 5. At this time, the second button protrusion 32 moves away from the second switch 42, preventing accidental activation of the second switch 42. When the second button protrusion 32 is pressed, the second contact position of the button 3 near the second switch 42, for example, the surface of the button 3 near the second switch 42, applies pressure to the second switch 42 to activate it. This causes the motor shaft of the motor 2 to rotate in a second direction via the controller 5. At this time, the first button protrusion 31 moves away from the first switch 41, preventing accidental activation of the first switch 41. Thus, the operator can only activate one of the first switch 41 and the second switch 42, thereby preventing accidental operation.

[0047] In another embodiment, the operator toggles the first button protrusion 31, causing the button 3 to rotate around the connecting shaft 33. The first button protrusion 31 activates the first switch 41 on the switch circuit board 43, driving the motor shaft of the motor 2 to rotate in a first direction. The operator toggles the second button protrusion 32, causing the button 3 to rotate in the opposite direction around the connecting shaft 33. The second button protrusion 32 activates the second switch 42, driving the motor shaft of the motor 2 to rotate in a second direction. Here, "toggling" refers to pressing or pushing in a direction other than perpendicular to the first flat portion S13. For example, touching the first arcuate surface S11 or the second arcuate surface S12 at any angle causes the button 3 to pivot. In this embodiment, even if the operator does not directly press the first button protrusion 31 or the second button protrusion 32, but pushes the first button protrusion 31 or the second button protrusion 32 from the side or at an angle, or if the applied force forms a component force in the direction perpendicular to the first flat portion S13, the switch corresponding to the first button protrusion 31 or the second button protrusion 32 can still be activated. Furthermore, even if the direction of the applied force is at an angle, the finger is unlikely to slip off the first or second end of the button 3, resulting in invalid or erroneous operation. Therefore, even when the operator's pressing action on the button 3 is not completely perpendicular to the first flat portion S13, the switch can be easily activated without accidentally touching another switch, facilitating control of the switch corresponding to the first button protrusion 31 or the second button protrusion 32 and ensuring high operational accuracy.

[0048] For example, refer to Figure 3 The stapler handle 100 also includes a connecting part 6, which extends along the axial direction D1. The proximal end of the connecting part 6 is connected to the handle body 10, and the distal end of the connecting part 6 is connected to the transmission assembly.

[0049] For example, the stapler handle 100 includes a handle body 10 and a connecting portion 6, with a button 3 disposed on the outer surface of the handle body 10. For example, a first switch 41 and a second switch 42 may be disposed within the handle body 10. For example, a motor 2 and a controller 5 may be disposed within the connecting portion 6 or within the handle body 10 to facilitate spatial arrangement of the various structures. Of course, the specific locations of the motor 2 and the controller 5 are not specifically limited in the embodiments of this utility model.

[0050] At least one embodiment of this utility model also provides a housing assembly 200 for a stapler handle. Exemplarily, Figure 5 This is a schematic diagram of a housing assembly 200 for a stapler handle according to an embodiment of the present invention. (Reference) Figure 5 The outer shell assembly 200 of the anastomosis device handle provided in at least one embodiment of the present invention includes a shell body and a shell button part 3a. The shell button part 3a has an integrated structure, is disposed on the shell body, protrudes from the outer surface of the shell body, and includes a first shell button protrusion 3a-1 and a second shell button protrusion 3a-2.

[0051] For example, the shell body includes a first shell portion 21 and a second shell portion 22. The first shell portion 21 includes a first main shell 211 and a shell button portion 3a. The first main shell 211 includes a first opening O1, and the outer surface of the first main shell 211 protrudes outward from the first opening O1. For example, the shell button portion 3a is disposed on the first main shell 211 and protrudes from the outer surface of the first main shell 211.

[0052] The outer shell assembly 200 of the stapler handle can be fitted onto the outside of the stapler handle provided in at least one embodiment of this utility model. The first shell portion 21 is fitted onto the side of the stapler handle 100 where the button 3 is provided, and the shell button portion 3a can be fitted onto the button 3 and fit against the button 3. Thus, the outer shell assembly 200 of the stapler handle can play a protective and isolating role, and also make it easy for the operator to feel the first button protrusion 31 and the second button protrusion 32. For example, the outer shell assembly 200 of the stapler handle is sterile and disposable. Before using the stapler for surgical operations, a sterile disposable protective shell can be used to cover the surface of the stapler handle 100, thereby avoiding direct sterilization of the stapler handle 100 and causing damage to the components in the stapler handle 100. The stapler handle 100 can be reused, for example, the disposable protective shell can be replaced the next time the stapler is used.

[0053] For example, refer to Figure 5The housing button portion 3a has a second working surface S2 away from the outer surface of the first main housing 211. The second working surface S2 has a first end and a second end opposite each other in the longitudinal direction D2, and a second flat portion S23 located between the first end and the second end. The first housing button protrusion 3a-1 is a protrusion located at the first end of the working surface and protruding from the second flat portion S23, and the second housing button protrusion 3a-2 is a protrusion located at the second end of the second working surface S2 and protruding from the second flat portion S23. Thus, the first housing button protrusion 3a-1 and the second housing button protrusion 3a-2 can be fitted together on the first button protrusion 31 and the second button protrusion 32, respectively.

[0054] For example, refer to Figure 5 The first main housing 211 extends longitudinally along D2, and the first housing button protrusion 3a-1 and the second housing button protrusion 3a-2 are arranged longitudinally along D2. The first main housing 211 has an upper end and a lower end opposite to each other in the longitudinal direction D2. During the use of the stapler, the lower end of the first main housing 211 corresponds to the lower end of the handle body 10 of the stapler that is close to the ground. The first housing button protrusion 3a-1 is located on the side of the second housing button protrusion 3a-2 away from the lower end of the first main housing 211. In the direction perpendicular to the second flat portion S23, the height of the first housing button protrusion 3a-1 protruding from the second flat portion S23 is greater than the height of the second housing button protrusion 3a-2 protruding from the second flat portion S23. That is, the first housing button protrusion 3a-1 protrudes more than the second housing button protrusion 3a-2 to adapt to the fact that the first button protrusion 31 of the handle body 10 protrudes more than the second button protrusion 32, thereby better fitting the first button protrusion 31 and the second button protrusion 32.

[0055] For example, the housing assembly 200 also includes a button connection portion (not shown), which is connected to the housing button portion 3a and the first main housing 211 respectively, and the housing button portion 3a is movable relative to the first main housing 211.

[0056] For example, the material of the shell button part 3a is a flexible material, such as soft rubber, silicone, rubber, soft plastic (such as polyethylene, polypropylene), TPU (polyurethane elastomer), TPE (thermoplastic elastomer), etc. Flexible materials are soft to the touch and have a certain degree of elasticity, so that the shell button part 3a fits the button 3 better, has a good feel, and makes it easier to accurately feel the first button protrusion 31 and the second button protrusion 32.

[0057] Alternatively, the button connection part can be made of a flexible material, while the button housing 3a can be made of a rigid material. For example, the second working surface S2 of the button housing 3a can be made of a rigid material, while the outer contour edge of the second working surface S2 can be made of a flexible material. A portion of the outer contour edge of the second working surface S2 can form the first housing button protrusion 3a-1 and the second housing button protrusion 3a-2, which are correspondingly attached to the outer contour edge of the first working surface S1 of the button 3. This allows the outer contour edge of the second working surface S2 to fit more closely, and provides a better tactile experience for the user. Rigid materials can be, for example, hard plastics (such as polypropylene, polycarbonate, and polyethylene).

[0058] It should be noted that, here, the outer contour edge of the second working surface S2 refers to the edge of the shell button part 3a formed by the outer contour edge. The material of this edge is a flexible soft material. That is, not only the outer contour edge line of the second working surface S2 is a soft material, but also the three-dimensional edge part surrounding the outer contour edge line of the second working surface S2 is a soft material.

[0059] For example, the material of other parts such as the first main shell 211 is not limited. It can be a rigid material, that is, a hard material, which has no elasticity to the touch, or it can be a soft material.

[0060] For example, refer to Figure 5 The outer shell assembly 200 of the stapler handle further includes a second shell portion 22, which includes a second opening O2. When the outer shell assembly 200 of the stapler handle is fitted onto the stapler handle 100, the first shell portion 21 is fitted onto the distal end of the stapler handle 100, and the second shell portion 22 is fitted onto the proximal end of the stapler handle 100. The first shell portion 21 and the second shell portion 22 are rotatably connected. When the first shell portion 21 and the second shell portion 22 are closed, a cavity is formed inside to accommodate the stapler handle 100 provided by this utility model. When the first shell portion 21 and the second shell portion 22 are closed, the second opening O2 aligns with the first opening O1. For example, the tops of the first housing portion 21 and the second housing portion 22 are connected by a rotatable connection structure so that when the outer housing assembly 200 of the stapler handle is opened, the second housing portion 22 can remain connected to the first housing portion 21 via the rotatable connection structure. Then, a portion of the stapler handle 100 is accommodated in the first housing portion 21, and the second housing portion 22 is then mated with the first housing portion 21 to form a sealed connection. This facilitates the accuracy and convenience of mating the second housing portion 22 with the first housing portion 21. For example, the rotatable connection structure is a rotating shaft hinge structure, which includes a rotating shaft R, and the two are connected via the rotating shaft hinge structure.

[0061] For example, refer to Figure 5The first main housing 211 extends along the longitudinal direction D2 and has a lower end and an upper end that are opposite to each other in the longitudinal direction D2. During the use of the stapler, the lower end of the first main housing 211 is installed on the lower end of the handle body 10 of the stapler near the ground. The first housing part 21 also includes a first axial housing 212, which is connected to the upper end of the first main housing 211. The sub-opening of the first main housing 211 communicates with the sub-opening of the first axial housing 212 to form a first opening O1. The second housing part 22 includes a second main housing 221, which extends along the longitudinal direction D2 and has a lower end and an upper end that are opposite to each other in the longitudinal direction D2. For example, the second housing portion 22 further includes a second axial housing 222, which is connected to the upper end of the second main housing 221. The sub-opening O21 of the second main housing 221 communicates with the sub-opening O22 of the second axial housing 222 to form a second opening O2. When the outer shell assembly 200 of the stapler handle is fitted onto the stapler handle 100, the sub-opening O11 of the first main housing 211 aligns with the sub-opening O21 of the second main housing 221, and the sub-opening O12 of the first axial housing 212 aligns with the sub-opening O22 of the second axial housing 222. Thus, the outer shell assembly 200 of the stapler handle covers the stapler handle 100 to provide protection and isolation.

[0062] At least one embodiment of this utility model also provides a stapler. Exemplarily, Figure 6 This is a schematic diagram of the first part of a stapler provided in one embodiment of the present invention. Figure 7 This is a schematic diagram of the second part of a stapler provided in one embodiment of the present invention. Figure 8 This is a schematic diagram of the cutting device and transmission components. (Reference) Figure 6-8 The stapler provided in one embodiment of this utility model includes a stapler handle 100, a cutting device 306, a transmission assembly 30, and a jaw assembly 303. The jaw assembly 303 is configured to be openable or closable. The transmission assembly 30 extends axially along D1 and includes a drive rod 305 within a second sleeve 302 and a lead screw shaft 307 within a first sleeve 301. The proximal end of the lead screw shaft 307 is connected to a motor 2, and the distal end of the drive rod 305 is connected to the cutting device 306. Figure 7 As shown, when the second sleeve 302 and the first sleeve 301 are connected, the drive rod 305 and the lead screw shaft 307 are connected. The motor shaft of motor 2 rotates in the second direction to drive the transmission assembly 30 to move along the axial direction D1 toward the distal end of the stapler, thereby driving the cutting device 306 to move toward the distal end of the stapler. The motor shaft of motor 2 rotates in the first direction to drive the transmission assembly 30 to move along the axial direction D1 toward the proximal end of the stapler, thereby driving the cutting device 306 to move toward the proximal end of the stapler.

[0063] For example, refer to Figure 6-8 When installing the stapler, the proximal end 300a of the first sleeve 301 is connected to the stapler handle 100, and the proximal end of the second sleeve 302 is connected to the distal end of the first sleeve 301.

[0064] For example, the stapler handle 100 is used to connect to the stapler's transmission assembly 30, which extends along the axial direction D1 and is used to control the operation of the stapler's jaw assembly 303. When the second button protrusion 32 is pressed, the motor shaft of the motor 2 rotates in the second direction to drive the transmission assembly 30 to move along the axial direction D1 toward the distal end of the stapler, thereby driving the cutting device 306 to move along the axial direction D1 toward the distal end of the stapler until the cutting device 306 (or closing mechanism) drives the first jaw 3031 and the second jaw 3032 of the jaw assembly 303 to engage with each other to perform the jaw assembly closing process; and, during the movement toward the distal end, the cutting device 306 drives the pusher slider to move toward the distal end, pushing out the staples in the second jaw 3032 to suture and cut the tissue. When the first button protrusion 31 is pressed, the motor shaft of the motor 2 rotates in the first direction to drive the transmission assembly 30 to move along the axial direction D1 toward the proximal end of the stapler, thereby driving the cutting device 306 (or closing mechanism) connected to the transmission assembly 30 to move toward the proximal end of the stapler, so that the cutting device 306 releases the first clamp 3031 and the second clamp 3032 that are engaged with each other to open the jaw assembly 303; at this time, if the first button protrusion 31 is pressed again, the cutting device 306 can continue to move toward the proximal end of the stapler, thereby retracting the cutting device 306 or the closing mechanism back to the proximal end, for example, back to the initial position, completing the retraction process.

[0065] For example, refer to Figure 6 The stapler also includes a housing assembly 200 for the stapler handle, which is fitted onto the stapler handle 100. The outline shape of the housing button portion 3a matches the outline shape of the button 3. At least the housing button portion 3a is fitted onto the button 3, for example, it is attached to the button 3, so that the fingers of the doctor or other user can accurately feel the first button protrusion 31 and the second button protrusion 32 of the button 3 on the surface of the housing button portion 3a, thus obtaining a better user feel.
