Line end is cyclic annular lock.Locking wire casing has threaded shaft in it, and end is equipped with cable clamping interface, and top is equipped with pulling wire handle.It uses
The device can realize that the surface of a wound is perforated or ruptured to the bladder wall carries out intracavitary suture, improves per urethra intracavity operation under cystoscope
Safety and certainty, increase to the remedial measure of unexpected vesical perforation postoperative complication.
2, self-locking of the invention band needle suture head end connects 3/8 radian sewing needle, which is not only conducive to instrument warp
Cystoscope enters in bladder cavity, is also conducive to intracavitary single instrument and realizes suture operation.
3, self-locking band needle suture of the invention is divided into common section and barb teeth section, and hangnail section slightly has thickening, between two sections
Excessively continue, without obvious boundary, suture pass through tighten after the bladder wall tissue it is more smooth, when end hangnail toothing passes through tissue
Has the function of one-way locking.
4, barb teeth section suture of the invention penetrates after annular lock, it can be achieved that individual event is locked, and sutures sending for tissue
Into controllable, cumbersome without intracavitary progress knotting operation, not only facilitates operation but also elastic adjustment is more accurate.
5, cyclic annular lock longitudinal section of the invention is that parallelogram sturcutre is conducive to secured locking wire, only barb teeth section is allowed to stitch
Zygonema is unidirectionally slided, and common section can be free to slide, keeps suture lock next more definite.
6, locking wire casing of the invention can mainly realize the cyclic annular lock locking suture of promotion, and threaded shaft is arranged inside by suture
Stump, which is put into cable clamping interface drawing, to be greatly improved threading efficiency into locking wire casing.
7, threaded shaft of the invention, the threaded shaft end are equipped with ring structure cable clamping interface, it can be achieved that suture stump U-typed
It is fixed, it avoids slipping during suture sleeve pipe, it is easy to operate.
8, the design of the invention is scientific and reasonable, fills up the blank of the intracavitary suturing skill of per urethra, in the premise for not increasing notch
Lower realize carries out intracavitary suture to the bladder wall perforation surface of a wound, improves the safety and certainty of per urethra intracavity operation, shortens
The time of patient's indwelling catheter.

Specific embodiment
Below by specific embodiment, the invention will be further described, and it is not limit that following embodiment, which is descriptive,
Qualitatively, this does not limit the scope of protection of the present invention.
A kind of per urethra bladder videoendoscopic surgery is set with intracavitary sewing needle, and innovation is: being stitched including self-locking band needle
Zygonema 2 and locking wire casing 6, head end of the self-locking with needle suture connect 3/8 radian sewing needle 1, and tail portion is with hangnail dentation
Structure 3, line end are cyclic annular lock 4.Locking wire casing has threaded shaft 7 in it, and threaded shaft end is equipped with cable clamping interface 5, and top is equipped with
Pulling wire handle 8.The blank of the intracavitary suturing skill of per urethra has been filled up, has been realized under cystoscope to the bladder wall perforation surface of a wound suture, is mentioned
High operation safety and certainty, shorten the time of indwelling catheter.
3/8 radian sewing needle 1 of the self-locking with needle suture head end, the radian are not only conducive to instrument and enter wing through cystoscope
Guang is intracavitary, is also conducive to intracavitary single instrument and realizes suture operation.
3 suture of barb teeth section penetrates after annular lock 4, it can be achieved that individual event locking, carries out cumbersome knotting without intracavitary
Operation, not only facilitates operation but also elastic adjustment is more accurate.
4 longitudinal sections of ring-type lock are that parallelogram sturcutre is conducive to secured locking wire, only allow barb teeth section suture unidirectional
Sliding, and common section can be free to slide, keeps suture lock next more definite.
Locking wire casing 6 can mainly realize the cyclic annular lock locking suture of promotion, and suture stump is put into card line by interior threaded shaft
Slot drawing can enter locking wire casing and be greatly improved threading efficiency.
The threaded shaft end is equipped with ring structure cable clamping interface 5, it can be achieved that suture stump U-typed is fixed, and suture is avoided to lead
It draws sleeve pipe to slip in the process, improves efficiency easy to operate.
The operation principle of the present invention is that:
Cystoscope per urethra enters in bladder cavity when operation, complete en bloc resection after, can the surface of a wound depth visible in detail,
Such as there is vesical perforation, per urethra bladder videoendoscopic surgery of the invention with intracavitary sewing needle by needle holder (subsequent to declare project) from
Bladder peephole handle hole is placed in bladder cavity, and line tail stays in vitro, and after the surface of a wound is sutured, suture needle pulls out external.In body
Outer to penetrate suture needle from the concave surface that ring-type latches, suture is cut in the patch crown portion after suitably tightening that carries out.The suture broken ends of fractured bone sandwiches card line
After slot, threaded shaft is pulled, suture is introduced into locking wire casing, hold with a firm grip locking wire casing and is pushed into, another hand on the other hand into bladder cavity
Suture can be pulled, suture is tightened, the dynamics of tightening line is adjusted according to lesion situation, the cyclic annular lock of patch cuts line tail and completes to suture
Operation.The present invention fills up the blank of the intracavitary suturing skill of per urethra, realizes that the surface of a wound is perforated or ruptured to the bladder wall carries out intracavitary seam
It closes, improves the safety and certainty of per urethra intracavity operation.
Although disclosing the embodiment of the present invention and attached drawing for the purpose of illustration, those skilled in the art can be managed
Solution: do not departing from the present invention and spirit and scope of the appended claims in, various substitutions, changes and modifications be all it is possible,
