Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a nerve disconnection stapler. Background Art

[0002] In existing surgical procedures, some of the diseased areas are blocked by nerve bundles. In this case, the nerve bundles need to be cut first, and then the diseased areas need to be surgically treated. After the surgical treatment is completed, the cut nerve bundles need to be connected. Since there are several nerve fibers in the nerve bundles and there is a lack of relevant medical equipment in the existing surgical treatment process, it is easy to cause nerve fiber dislocation when connecting the cut nerve bundles. Nerve fiber dislocation will prolong the patient's recovery time, so a nerve disconnection stapler is urgently needed. Summary of the invention

[0005] The material of the cut-off area is softer than that of other positions.

[0006] A first connecting platform is provided at the other end of the first extension part, and a second connecting platform is provided at the other end of the second extension part. A fixing protrusion is provided on the first connecting platform, and a fixing through hole matching the fixing protrusion is provided on the second connecting platform.

[0016] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.

[0017] The embodiment of the present invention relates to a nerve cutting stapler, such as Figure 1-Figure 4 As shown, it includes: a first extension part 1, a second extension part 2 and a connecting part 3; one end of the first extension part 1 is connected to one end of the connecting part 3; one end of the second extension part 2 is connected to the other end of the connecting part 3; the connecting part 3 is a flexible structure and has two states, when the connecting part 3 is in the first state, the other end of the first extension part 1 and the other end of the second extension part 2 are both suspended, when the connecting part 3 is in the second state, the other end of the first extension part 1 and the other end of the second extension part 2 are tightly attached, so that the first extension part 1, the second extension part 2 and the connecting part 3 form a ring body; the ring body is provided with a cutting area 4, and alignment marks 5 are provided on both sides of the cutting area 4.

[0018] When in use, the flexible structure 3 is in the first state, the other end of the first extension part 1 and the other end of the second extension part 2 form an opening, the nerve bundle is placed in the opening, and the cutting area 4 is adjusted to the position on the nerve bundle that needs to be cut. After completion, the flexible structure 3 is adjusted to the second state, and the ring formed by the first extension part 1, the second extension part 2 and the connecting part 3 surrounds the nerve bundle. At this time, a scalpel is used to perform a cutting operation in the cutting area 4 to achieve the cutting of the nerve bundle, and then the part blocked by the nerve bundle can be surgically treated. After the surgical treatment is completed, the nerve bundle is aligned according to the alignment mark 5, and then the cut nerve bundle is sutured. The alignment mark 5 of this embodiment can be a plurality of parallel lines of different colors, so that when aligning, it is only necessary to align the lines of the same color on both sides to achieve the alignment of the nerve fibers in the nerve bundle.

[0019] It can be seen that the present invention uses a flexible structural connection part to control the state of the first extension part and the second extension part, so that the ring formed by the first extension part, the second extension part and the connection part can surround the nerve bundle, and a cutting area is set on the ring so that the nerve bundle that needs to be cut can be cut during surgery. The alignment mark point of the cutting area can ensure that the nerve fiber dislocation can be avoided when connecting the nerves.

[0020] In this embodiment, the other end of the first extension part 1 is provided with a first connection platform 11, and the other end of the second extension part 2 is provided with a second connection platform 21. The first connection platform 11 is provided with a fixing protrusion 6, and the second connection platform 11 is provided with a fixing through hole 7 matching the fixing protrusion 6. When the fixing protrusion 6 is inserted into the fixing through hole 7, the other end of the first extension part 1 and the other end of the second extension part 2 are tightly attached, so that the first extension part 1, the second extension part 2 and the connection part 3 form the ring body. The cooperation between the fixing protrusion 6 and the fixing through hole 7 can ensure that the other end of the first extension part 1 and the other end of the second extension part 2 will not loosen after being tightly attached.

[0021] The ring body in this embodiment is also provided with a plurality of pairs of fixing holes 9, and the fixing holes 9 are used to insert fixing needles. Thus, through the fixation of the fixing needles, the ring body will not fall off from the nerve bundle even when the nerve bundle is cut off.

[0022] The two boundaries of the cutting area 4 of this embodiment are respectively provided with a first boss 12 and a second boss 22 extending radially along the ring body and toward the outside of the ring body, and suture holes 8 are provided on the first boss 12 and the second boss 22. The suture holes 8 on the first boss 12 correspond to the suture holes 8 on the second boss one by one, and the suture holes 8 are used to suture the cut nerve bundle. When in use, the suture thread only needs to be passed through the suture holes 8 on the first boss 12 and the suture holes 8 on the second boss 22 in sequence to complete the anastomosis of the nerve bundle, and the operation method is simpler and more efficient.
