[0032] Please refer to Figure 1-4 The present embodiment provides an electric tubular stapler with a multi-dimensional stereoscopic gripping structure, preferably a disposable electric tubular stapler with a multi-dimensional stereoscopic gripping structure, which is particularly suitable for clinical surgery that is disposable and does not require re-sterilization. The electric tubular stapler comprises a housing, a support frame, a kissing assembly, a curved connection assembly, a screw 31, an anvil assembly, a drive motor 48, a firing assembly, an adjustment nut 4, a protective cover 46 and a battery pack 49. The housing is coated on the outside of the support frame to effectively protect the support frame. The kissing assembly is mounted on one end of the support frame. The screw 31 passes through the kissing assembly and is connected to the anvil assembly through the curved connection assembly so that the anvil assembly and the kissing assembly are arranged opposite to each other and can be detached. The drive motor 48 is used to drive the kissing assembly to cut and sew. The firing assembly is used to control the start and stop of the drive motor 48. The battery pack 49 is used to provide the working power of the drive motor 48. The adjustment nut 4 drives the screw 31 to rotate on the support frame so that the anvil assembly moves toward or away from the kissing assembly and can move between the clamping position and the release position.

[0033] Please refer to Figure 2 , 36. The anastomosis assembly is installed on the support frame and can cut the digestive tract tissue 53. The outer shell is provided with an installation cavity, the end of the installation cavity passes through the end surface of the outer shell and a installation port is formed on the end surface of the outer shell. The support frame is installed in the installation cavity, and the anastomosis assembly is passed to the outside of the installation port, so as to effectively cut and suture the digestive tract tissue 53. Specifically, the support frame includes a left support frame 1 and a right support frame 2. The left support frame 1 and the right support frame 2 are assembled into a whole to support the anastomosis assembly, and a small plate assembly 24 is arranged on the support frame. The outer shell includes a left outer shell 47 and a right outer shell 50. The left outer shell 47 has a left handle, and the right outer shell 50 has a right handle. When the left outer shell 47 and the right outer shell 50 are assembled, the left handle and the right handle are assembled into a handle portion.

[0034] Please refer to Figure 1-6 The screw 31 can rotate on the support frame, the anvil seat assembly is arranged relative to the kiss-cutting assembly, and the bent connection assembly is respectively connected to the screw 31 and the anvil seat assembly so that the axes of the screw 31 and the anvil seat assembly intersect. As the screw 31 rotates, the anvil seat assembly can move between the clamping position and the release position so as to cooperate with the kiss-cutting assembly to clamp and release the digestive tract tissue 53. A three-dimensional grasping structure (multi-dimensional three-dimensional grasping structure) for accommodating the digestive tract tissue 53 is arranged between the kiss-cutting assembly and the anvil seat assembly, and the kiss-cutting assembly and the anvil seat assembly are detachably connected. Therefore, by setting a curved connection assembly and making the axes of the screw 31 and the anvil assembly intersect, the curvature of the curved connection assembly can be adapted to the digestive tract such as the esophagus, stomach, and intestines, so that the anvil assembly and the staple assembly can effectively enter the digestive tract; by rotating the screw 31 on the support frame, the relative positions of the staple assembly and the anvil assembly on the support frame are adjusted, so that the digestive tract tissue 53 can enter the three-dimensional grasping structure between the anvil assembly and the staple assembly and clamp the digestive tract tissue 53, and then the anvil assembly and the staple assembly cooperate to cut and suture the digestive tract tissue 53.

[0035] Please refer to Figure 1-6 The stapler also includes an adjusting nut 4, which is used to enable the screw 31 to rotate on the support frame and move the anvil assembly between the clamping position and the release position, so that the rotation of the adjusting nut 4 on the support frame can drive the screw 31 to rotate and provide power for the movement of the anvil assembly. Specifically, a compression spring 3 is arranged between the adjusting nut 4 and the support frame. When the adjusting nut 4 rotates counterclockwise on the support frame, the compression spring 3 is compressed, and the screw 31 drives the anvil assembly to move away from the anastomosis assembly, thereby enabling the anvil assembly to move to the release position; when the adjusting nut 4 rotates clockwise on the support frame, the compression spring 3 is stretched, and the screw 31 drives the anvil assembly to move toward the anastomosis assembly, thereby enabling the anvil assembly to move to the clamping position and clamp the digestive tract tissue 53 in the three-dimensional grasping structure.

[0036] Please refer to Figure 1-4 An adjusting nut cover 5 is provided on the end of the adjusting nut 4 away from the screw rod 31 , one end of the compression spring 3 is connected to the adjusting nut 4 through a fastening ring 6 , and the screw rod 31 is locked on the adjusting nut 4 through an adjusting nut pin 7 .

[0037] Please refer to Figure 3-4 The driving motor 48 is used to control the action of the anastomosis assembly, and the firing assembly is used to control the start and stop of the driving motor 48. The driving motor 48 is used to provide the kinetic energy required for the operation of the anastomosis assembly, and the firing assembly is used to control the start and stop of the driving motor 48, so that when the digestive tract tissue 53 is cut, the cutting speed can be kept constant, which is conducive to improving the neatness of the surface of the cut digestive tract tissue 53. When the digestive tract tissue 53 is sutured, the nail pushing speed is kept constant, which can avoid the phenomenon of poor nail shape.

[0038] Please refer to Figure 3-4 The firing assembly includes a firing trigger 8, a firing trigger connecting rod 9, a firing trigger torsion spring 10 and a firing connecting rod 22. The firing trigger 8 can rotate on the support frame. The firing trigger 8 is provided with a mounting groove for installing the firing trigger torsion spring 10. The firing trigger torsion spring 10 is installed on the mounting groove through a trigger groove pin 11. The two ends of the firing trigger torsion spring 10 are respectively connected to the firing trigger 8 and the firing trigger connecting rod 9. The firing connecting rod 22 slides horizontally on the support frame through the firing connecting rod sliding pin 23. The rotation of the firing trigger 8 can drive the firing connecting rod 22 to slide horizontally on the support frame. The adjusting block 26 is installed on the screw rod 31 through a screw 35, and the adjusting block 26 is connected to the firing connecting rod 22 in transmission.

[0039] Please refer to Figure 5-6 The three-dimensional grasping structure includes a nail outlet 54 and a digestive tract tissue accommodating groove. The nail outlet 54 is formed on the anastomosis assembly, and the digestive tract tissue accommodating groove is formed between the anastomosis assembly and the anvil assembly. In this way, when the anvil assembly moves to the clamping position, the digestive tract tissue 53 can enter the digestive tract tissue accommodating groove and clamp the digestive tract tissue 53. The staples in the anastomosis assembly are pushed out of the nail outlet 54 to cut and suture the digestive tract tissue 53 in the digestive tract tissue accommodating groove. The three-dimensional grasping structure adopts 3D three-dimensional grasping technology, so that the digestive tract tissue 53 to be sutured is in a wavy state, and the digestive tract tissue 53 is not tight, thereby reducing the damage to the digestive tract tissue 53. Specifically, the digestive tract tissue accommodating groove is formed by the end surface of the anvil assembly facing the suturing assembly being recessed toward the end surface of the anvil assembly facing away from the suturing assembly, even if the nail outlet 54 and the digestive tract tissue accommodating groove are respectively formed on the suturing assembly and the anvil assembly, the structures of the anvil assembly and the anvil assembly are reasonably utilized, and more accommodation space is provided for the digestive tract tissue 53, which is conducive to better reducing the damage to the digestive tract tissue 53. More specifically, the nail outlet 54 is preferably an elliptical hole, which is conducive to improving the nail outlet efficiency and suturing effect.

[0040] Please refer to Figure 3-4 The anastomosis assembly includes a staple magazine sleeve 37, a staple magazine 38 and an annular knife pushing staple piece assembly 39. The three-dimensional grasping structure is arranged between the staple magazine 38 and the staple support assembly. The staple magazine sleeve 37 has a receiving cavity for receiving staples. The staple magazine 38 is connected to the staple magazine sleeve 37 to cover the receiving cavity and connect the three-dimensional grasping structure with the receiving cavity. The driving motor 48 is used to drive the action of the annular knife pushing staple piece assembly 39. In this way, the screw rod 31 passes through the staple magazine 38 and the staple magazine sleeve 37 and is connected to the staple support assembly. By rotating the firing trigger 8, the driving motor 48 drives the firing connecting rod 22 to drive the annular knife pushing staple piece assembly 39 to slide on the support frame to push the annular knife and the staples out, thereby completing the effective cutting and suturing of the digestive tract tissue 53.

[0041] Please refer to Figure 3-4 The nail magazine 38 and the nail magazine sleeve 37 are detachably connected. Preferably, the nail magazine 38 and the nail magazine sleeve 37 are clamped together. A clamping block is provided on the nail magazine 38, and a clamping hole 55 is provided on the nail magazine sleeve 37. When the nail magazine 38 is installed on the nail magazine sleeve 37, the clamping block is clamped with the clamping hole 55, thereby realizing the effective connection between the nail magazine 38 and the nail magazine sleeve 37. In another embodiment, the clamping block is provided on the nail magazine sleeve 37, and the clamping hole 55 is provided on the nail magazine 38.

That is, the staple outlets 54 are formed on the staple magazine 38, and are arranged in two rows around the circumferential direction of the staple magazine 38, and the staple outlets 54 are arranged staggered. The digestive tract tissue accommodating groove is formed on the side of the staple support 40 facing the staple magazine 38, so that the staples can be inserted and removed from the digestive tract tissue 53, forming two rows of staggered staples arranged in a circular manner, and the inner digestive tract tissue 53 is cut off with a circular knife, so as to perform a quick and easy anastomosis of the digestive tract tissue 53. The 3D stereoscopic grasping technology provides precise squeezing of the digestive tract tissue 53 that needs to be sutured, reducing the damage to the digestive tract tissue 53. The gentle operation is optimized, and the squeezing force of the digestive tract tissue 53 is effectively reduced to a certain extent.

[0044] Please refer to Figure 3-4The curved connection assembly includes a tab portion and a connecting rod portion. The tab portion is connected to the screw rod 31 and the anvil seat assembly respectively so that the axes of the screw rod 31 and the anvil seat assembly intersect, and the connecting rod portion is sleeved on the tab portion. In this way, when the screw rod 31 rotates, the anvil seat assembly can be driven to move between the clamping position and the release position through the tab portion, and the firing assembly can drive the connecting rod portion to slide on the screw rod 31 to drive the kiss cutting assembly to cooperate with the anvil seat assembly to complete the cutting and suturing of the digestive tract tissue 53. Specifically, the tab portion includes a first tab 32 and a second tab 33, and the connecting rod portion includes a first connecting rod and a second connecting rod. The first connecting rod is set as a long connecting rod 29, and the second connecting rod is set as a short connecting rod 30. More specifically, the first tab 32 and the second tab 33 are as a whole, and their two ends are connected to the screw rod 31 and the guide shaft 25 through the screw groove pin 34 and the guide shaft groove pin 43 respectively. Such a configuration can optimize the structure of the curved connection assembly.

[0045] Please refer to Figure 3-4 The bending connection component also includes a bend pipe 28, which is sleeved on the connecting rod part and connected to the kiss-cutting component and the support frame respectively, so as to protect the pull-tab part and the connecting rod part.

[0046] Please refer to Figure 3-4 The bending connection component is made of a flexible and bendable material, that is, the pull-tab portion, the connecting rod portion, the curved pipe 28 and other components are made of aluminum, thereby making the bending connection component easy to manufacture and achieve a preset curvature.

[0047] Please refer to Figure 3-4 The curved connection assembly passes through the guide shaft 25 to pass through the kiss cutting assembly, and the spring tube 42 on the anvil seat 40 can clamp the guide shaft 25 to achieve a detachable connection between the anvil seat assembly and the screw rod 31. In this way, the anvil seat assembly can be placed in the digestive tract tissue 53 to complete the cutting and suturing of the digestive tract tissue 53 when in use.

[0048] Please refer to Figure 3-4 The driving motor 48 is connected to the anastomosis assembly through a transmission assembly to control the movement of the anastomosis assembly.
