[0025] Example

[0026] Reference Figure 1-4 This is an embodiment of the present invention, which provides a laparoscopic anastomosis device for easy and precise cutting, comprising:

[0027] The housing assembly 100 includes a housing 101, a handheld part 102 disposed at the lower end of the housing 101, a trigger 103 rotatably mounted on the lower end side wall of the housing 101, a fixing plate 104 fixedly connected to the end side wall of the housing 101, and a positioning seat 105 adapted to be mounted on the end of the fixing plate 104.

[0028] The cutting assembly 200 includes a push rod 201 that is movably inserted into the middle of the fixed plate 104, an adapter plate 202 installed on the side wall of the push rod 201, a mounting base 203 that is snapped into the end of the adapter plate 202, and a nail head 204 that is adapted to be installed on the side wall of the mounting base 203. The nail head 204 is used in conjunction with the positioning base 105.

[0029] The outer shell 101 provides protection and support for the entire instrument. The handheld part 102 at its lower end is ergonomically designed for easy gripping and operation by doctors. The trigger 103 is rotatably mounted on the lower side wall of the outer shell 101 and is the main control component for doctors to operate the instrument. The fixing plate 104 is fixedly connected to the end side wall of the outer shell 101 and is used to install and position other components. The positioning seat 105 is adapted to be installed at the end of the fixing plate 104 and works in conjunction with the cutting assembly 200 to provide a precise positioning reference for cutting and anastomosis operations. The cutting assembly 200 is ingeniously designed, and all components work together to achieve precise cutting. The push rod 201 is movably inserted into the middle of the fixing plate 104 and can move linearly under the guidance of the fixing plate. The adapter plate 202 is installed on the side wall of the push rod 201 and moves with the push rod. The mounting seat 203 is snapped into the end of the adapter plate 202. The screw head 204 is adapted to be installed on the side wall of the mounting seat 203. The screw head 204 cooperates with the positioning seat 105 to complete the anastomosis of tissues while cutting.

[0030] Specifically, the cutting assembly 200 also includes a connecting rod 205 fixedly connected to the end of the push rod 201, a pull rod 206 rotatably connected to the end of the connecting rod 205, and a button 207 snapped onto the side wall of the housing 101. The end of the pull rod 206 is hinged to the inner wall of the housing 101, and the end of the button 207 is in elastic contact with the side wall of the pull rod 206.

[0031] The connecting rod 205 is rotatably mounted on the end of the push rod 201, and the pull rod 206 is rotatably mounted on the end of the connecting rod 205. The end of the pull rod 206 is hinged to the inner wall of the housing 101, and the button 207 is snapped into the side wall of the housing 101 with its end in elastic contact with the side wall of the pull rod 206. When the button 207 is pressed, the button pushes the pull rod 206 to rotate around the hinge point, which in turn drives the push rod 201 to move through the connecting rod 205.

[0032] Furthermore, the cutting assembly 200 also includes a slider 208 slidably installed inside the housing 101, and a spring 209 fixedly connected to the side wall of the slider 208. The spring 209 is fixedly connected to the side wall of the push rod 201. The slider 208 is disposed above the connecting rod 205. The cutting assembly 200 also includes a toggle member 210 fixedly connected to the end of the slider 208. The end of the slider 208 is movably inserted into the middle of the strip on the side wall of the housing 101, and the toggle member 210 is installed on the outside of the housing 101.

[0033] The sliding member 208 is slidably installed inside the housing 101. One end of the spring 209 is fixedly connected to the side wall of the sliding member 208, and the other end is fixedly connected to the side wall of the push rod 201. The sliding member 208 is positioned above the connecting rod 205. The spring 209 provides elastic force, enabling the push rod 201 to buffer and reset during movement. The actuating member 210 is fixedly connected to the end of the sliding member 208, and the end of the sliding member 208 is movably inserted into a slot in the side wall of the housing 101. The actuating member 210 is located outside the housing 101. The doctor can directly control the position of the sliding member 208 by adjusting the actuating member 210, thereby indirectly adjusting the position and state of the push rod 201.

[0034] Preferably, the cutting assembly 200 further includes an arc-shaped block 211 rotatably mounted on the inner wall of the housing 101, and a support rod 212 rotatably mounted on the bottom side wall of the arc-shaped block 211, such that the upper end of the arc-shaped block 211 slides in contact with the bottom side wall of the pull rod 206, and the lower end of the support rod 212 is rotatably connected to the trigger 103 side. The cutting assembly 200 also includes a locking block 213 adapted to be mounted on the side wall of the trigger 103, with the end of the locking block 213 engaging with the bottom side wall of the arc-shaped block 211.

[0035] The arc-shaped block 211 is rotatably mounted on the inner wall of the housing 101, and the support rod 212 is rotatably mounted on the bottom side wall of the arc-shaped block 211. The upper end of the arc-shaped block 211 slides in contact with the bottom side wall of the pull rod 206, and the lower end of the support rod 212 is rotatably connected to the trigger 103. When the trigger 103 is pressed, the support rod 212 pushes the arc-shaped block 211 to rotate, and the arc-shaped block 211 then pushes the pull rod 206, thereby achieving further control of the push rod 201. The locking block 213 is adapted to be mounted on the side wall of the trigger 103, and its end is locked into the bottom side wall of the arc-shaped block 211 to lock the relative position of the trigger 103 and the arc-shaped block 211, ensuring the stability of the instrument during operation.

[0036] Preferably, the cutting assembly 200 further includes a rotating rod 214 rotatably mounted on the inner wall of the housing 101, a limiting block 215 threadedly connected to the end of the rotating rod 214, and a gear 216 rotatably connected to the side wall of the housing 101. The side wall of the gear 216 meshes with the rack at the end of the rotating rod 214, and the end of the limiting block 215 is fixedly connected to the side wall of the adapter plate 202.

[0037] The rotating rod 214 is rotatably mounted on the inner wall of the housing 101. The limiting block 215 is threadedly connected to the end of the rotating rod 214. The gear 216 is rotatably connected to the side wall of the housing 101, and its side wall meshes with the rack at the end of the rotating rod 214. By rotating the gear 216, the rotating rod 214 can be rotated, thereby adjusting the position of the limiting block 215. Since the end of the limiting block 215 is fixedly connected to the side wall of the adapter plate 202, the position of the adapter plate 202 and the nail head 204 connected to it can be precisely controlled, achieving precise cutting and fitting.

[0038] In use, the doctor first holds the handpiece 102 and places the stapler on the tissue site to be operated on. The positioning seat 105 is used for precise positioning with the tissue. If the position of the staple head 204 needs to be adjusted, the gear 216 can be rotated, and fine adjustments can be made through the rotating rod 214 and the limiting block 215. When ready, the doctor can press the button 207, which moves the push rod 201 through the pull rod 206 and the connecting rod 205, pushing the staple head 204 to perform cutting and anastomosis operations. At the same time, the doctor can also press the trigger 103 to further control the movement of the pull rod 206 and the push rod 201 through the support rod 212 and the arc block 211. After the operation is completed, the button 207 and the trigger 103 are released. Under the action of the spring 209, the push rod 201 and other components are reset. The doctor can also adjust the position of the sliding part 208 and the push rod 201 by adjusting the toggle part 210.

[0039] In summary, the precise positioning of the positioning seat 105 and the accurate control of the position of the screw head 204 by components such as the rotating rod 214 and the limiting block 215 greatly improve the accuracy of cutting and reduce damage to surrounding healthy tissues. In terms of ease of operation, the dual control design of the button 207 and the trigger 103, as well as the auxiliary adjustment function of the toggle piece 210, allow doctors to operate flexibly according to the actual situation of the surgery, reducing the difficulty of operation and improving the efficiency of surgery. The stability of the instrument is also significantly improved. The locking mechanism of the locking block 213 and the arc block 211 ensures that no part will move unexpectedly during operation, guaranteeing the smooth progress of the surgery.
