Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a lock catch type ligation tightening ring and application thereof.
Background
With the insights into sacral cysts, most scholars agree to clinically classify sacral cysts purely: it contains two types of nerve root and nerve root-free type. The method is a precondition for treating the sacral canal cyst by standard microsurgery, and the corresponding operation modes of the two types of sacral canal cyst are root-sleeve reconstruction and capsule cervical suture. If no nerve root is determined in the sacral canal cyst, direct ligation of the cyst neck, namely cyst leak, can be considered to block the source of cyst fluid, thereby effectively treating the sacral canal cyst without nerve root in the sacral canal cyst.
At present, in clinical operation, the method for ligating the capsule neck does not leave an operation suture (silk thread), and adopts two modes of bundling and sewing, or combines the two methods for application. Both require that the art has consummate microneurosurgery operation gimmick, this itself has restricted the general popularization and application of operation mode, especially in popularization and popularization of base level hospital such as county and city level, and when traditional art formula is sewed up the sack neck, partial needle eye weeping to and the space cyst wall between two adjacent needles, later stage because of the terminal pressure increase of dural sac swells once more, the cyst appears again.
Disclosure of Invention

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the invention discloses a lock catch type ligation tightening ring, which comprises a tightening belt 1 made of PEEK material and a lock catch 2. The tightening belt 1 is a flat strip-shaped structure, two ends of the tightening belt 1 are bent oppositely, and the ends of the two ends of the tightening belt 1 are aligned. The lock catch 2 comprises an outer shell 21 which is integrally in a circular truncated cone shape, a fastening hole 211 which is arranged along the axial direction of the outer shell 21 is formed in the outer shell 21, the small head end of the outer shell 21 is an insertion end, and the large head end of the outer shell 21 is a penetrating end. The aligned ends of the two ends of the fastening band 1 are inserted into the fastening holes 211 from the insertion end of the housing 21 and slide relatively to the fastening holes 211 in a one-way irreversible manner.
The binding band 1 comprises a binding section 11 positioned in the middle and clamping sections 12 positioned at two ends of the binding section 11, and the binding section 11 and the clamping sections 12 are integrally formed. On the surface of the same side of the two clamping sections 12, a concave cavity 121 is arranged along the length direction of the clamping section 12, a plurality of engaging teeth 122 inclined towards the binding section 11 are arranged inside the concave cavity 121 along the length direction of the clamping section 12, and the engaging teeth 122 and the clamping section 12 are integrally formed. At one end of the clamping section 12 connected to the binding section 11, the size of the engaging teeth 122 on the clamping section 12 gradually decreases toward the binding section 11.
Referring to fig. 1 and 2, the fastening hole 211 is a rectangular hole having a width dimension matching the width of the fastening section 12, and the length dimension of the fastening hole 211 is larger than the belt thickness dimension of the fastening belt 1. Elastic latch teeth 22 are respectively arranged on two side walls in the length direction of the fastening hole 211, and the elastic latch teeth 22 and the shell 21 are integrally formed. The elastic latch 22 is disposed obliquely from the drawing section of the housing 21 toward the insertion end of the housing 21.
The two elastic latches 22 located inside the fastening hole 211 are oppositely disposed. The distance between the two elastic teeth 22 is smaller than the band thickness dimension of the two fastening bands 1, and when the opposite elastic teeth 22 are bent and deformed in the direction away from each other, a space having a width larger than the band thickness of the two fastening bands 1 can be formed between the opposite elastic teeth 22.
The two fastening sections 12 of the fastening band 1 are bent and attached to each other, the engaging teeth 122 of the fastening sections 12 face outward, the folded fastening band 1 is inserted into the fastening hole 211 from the insertion end of the fastening hole 211 and penetrates the fastening hole 211, and when the fastening band 1 penetrates the fastening hole 211, the engaging teeth 122 of the fastening sections 12 face the elastic engaging teeth 22 inside the fastening hole 211. After the two fastening sections 12 of the fastening band 1 are simultaneously inserted through the fastening holes 211, a fastening ring is formed at the binding section 11.
When the two fastening sections 12 of the fastening band 1 pass through the fastening hole 211 at the same time, and when the two fastening sections 12 of the fastening band 1 move towards the penetrating end direction of the shell 21 in the fastening hole 211, the fastening sections 12 push the elastic latch 22, so that the opposite elastic latch 22 deforms towards the opposite direction, and the two folded and attached fastening sections 12 pass through between the opposite elastic latch 22. Because the elastic latch is inclined towards the insertion end of the fastening hole 211, and the engaging teeth 122 are inclined towards the binding section 11, when the clamping section 12 moves towards the penetrating end of the shell 21, the elastic latch 22 is sequentially clamped between the adjacent engaging teeth 122 to enable the elastic latch 22 to be engaged with the engaging teeth 122, so that the clamping section 12 cannot move towards the penetrating end of the shell 21.
An extension section 13 integrally formed with the clamping section 12 is arranged at one end of the clamping section 12 far away from the binding section 11, and the width of the extension section 13 is gradually reduced from one end connected with the clamping section 12 to one end far away from the clamping section 12. The surface of the extension 13 facing the tooth 122 is engraved with anti-slip lines 131, and the roughness of the surface of the extension 13 is increased by the anti-slip lines 131. The extension section 13 gradually narrows from one end connected with the fastening section 12 to the free end.
On one side surface of the binding section 11 facing the inner side of the formed binding ring, a plurality of cogs 111 integrally formed with the binding section 11 are arranged along the length direction of the binding section 11. When the binding section 11 binds and fixes the capsule neck, the blunt teeth 111 are embedded into the capsule neck tissue, thereby ensuring the firmness of the ligation of the capsule neck.
The end surfaces of the insertion end and the penetrating end of the shell 21 are fixed with the anchoring ring 3, and the anchoring ring 3 and the shell 21 are integrally formed.
The application of the lock catch type ligation tightening ring in the microshell operation without nerve root cyst: the cyst neck is furled after being dissociated, the cyst neck is made to be close to the root part of the tail end of the hard membrane sac as much as possible, a tying ring formed by a tying section 11 of a tying belt 1 is sleeved outside the cyst neck, a clamping section 12 is held by a hand and a lock catch 2 is pushed, so that the lock catch 2 moves towards the tying ring formed by the tying belt 1, the cyst neck is slowly pushed in the pushing process, the positions of the tying ring and the cyst neck are adjusted at any time, and the cyst neck is completely tied up until the tying section 11 of the tying belt 1. And finally, binding and fixing the parts of the clamping and fixing section 12 of the binding belt 1, which are positioned at the outer sides of the penetrating end and the inserting end of the lock catch, through silk threads, connecting the silk threads with the anchoring ring 3, and finally cutting off the redundant parts of the residual ends of the silk threads and the clamping and fixing section 12, which are positioned at the penetrating end of the lock catch 2.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
