Description

The suture ligature device using in endoscope-assistant surgery

Technical field

This utility model relates to medical apparatus and instruments, the suture ligature device of specifically for chamber mirror or endoscopic surgery, surgical wound being sewed up.

Background technology

Chamber mirror or endoscopic surgery are because the little ， visual field, working place is little, and postoperative ligation difficulty is large, so suture ligature all needs the instrument of helping each other.Similar instrument wire twister as disclosed in CN201617884U, mainly by handle, outer tube and tubule, formed, tubule is enclosed within outer tube, tubule front end can stretch out or retract at outer tube front end, when tubule front end stretches out outer tube front end, elasticity curls into the spiral coil of at least two circles, and the line that surgical ligation is used is through this tubule.During knotting, tubule is retracted in outer tube, ligature forms a circle or the above winding of two circles, and onto surgical ligation position is shifted the toe-in of winding in outer tube end, can tie a knot easily rapidly and make solid, but before knotting, need to sewing needle be carried out to sew application at operative site with pliers.While sewing up due to sewing needle, need certain angle and dynamics, pliers clips sewing needle to carry out sew application difficulty larger when sewing up under the mirror of chamber, and training time that need to be very long, and skilled surgical doctor sews up and all wastes time and energy under the mirror of chamber, increased operating time and sewed up reliability.

Summary of the invention

The purpose of this utility model is to provide a kind of can sew up the suture ligature device that acupuncture treatment operation is tied a knot simultaneously by handled easily sewing needle in chamber mirror or endoscopic surgery.

Suture ligature device of the present utility model comprises outer tube, tubule is enclosed within outer tube, tubule front end can stretch out or retract at outer tube front end, when tubule front end stretches out in outer tube front end, elasticity curls into the spiral coil of at least two circles, stitching thread is through this tubule, tubule front end has needle guard, and the rear sleeve of sewing needle is in this needle guard, and sutural front end connects sewing needle.

The further preferred version of this utility model is: needle guard sidewall has through hole, on tubule tube wall, has through hole, and stitching thread front end is connected with sewing needle rear end through the through hole of needle guard sidewall after through the through hole on tubule tube wall.

Above-mentioned needle guard can also be the sleeve that is fixed on tubule front end, or tubule front end tightly pushes the cylindrical body of formation through lasso.

Other preferred version is: in the front inner wall of tubule, have protruding spacing ring, stitching thread front end connects sewing needle rear end through the through hole in the middle of spacing ring.

Other preferred version is: needle guard sidewall has through hole, on tubule tube wall, has through hole, and stitching thread front end is connected with sewing needle rear end through the through hole of needle guard sidewall after through the through hole on tubule tube wall.

Sewing needle rear portion is preferably triangular prism shape, and the register hole of needle guard is corresponding triangular prism shape.

The front end outline of needle guard is preferably ellipse, and the front end of outer tube is corresponding oval trepanning.

The front end of above-mentioned outer tube can have the bending of 10-45 °.

This utility model is because outer tube and tubule have certain degree of hardness, outer tube and tubule are as the boosting instrument of sewing needle, the sewing needle that is convenient to operation is sewed up acupuncture treatment operation, outer tube and tubule leading portion can have the bending of certain angle, sewing needle can incline direction will be sewn the histoorgan laminating that furthers, the suture ligature device of then tiing a knot through surgical incision position.

The specific embodiment

Suture ligature device shown in Fig. 1, Fig. 2 comprises outer tube 1, and there is handle 2 at outer tube 1 rear portion, and the front end 3 of outer tube 1 can have the bending of 10-45 °.Tubule 4 is enclosed within outer tube 1, and there is operating handle 5 at tubule 4 rear portions, and tubule 4 front ends can stretch out at the front end of outer tube 1 or retract, and when tubule 4 front ends stretch out outer tube 1, can elasticity curl at least two spiral coils 6 that enclose, and sewing needle 8 is enclosed within the front end of tubule 6.

Shown in Fig. 3, the front end of tubule 4 has needle guard 7, and the rear sleeve of sewing needle 8, in needle guard 7, has through hole 9 on the tube wall of tubule 4, and stitching thread 10 is through tubule 1, and after through hole 9 passes, its front end connects the rear end of sewing needle 8.

In the embodiment of Fig. 4, the front end of tubule 4 has needle guard 7, the rear sleeve of sewing needle 8 is in needle guard 7, needle guard 7 sidewalls have through hole 11, on the tube wall of tubule 4, have through hole 9, the front end of stitching thread 10 is connected with the rear end of sewing needle 8 through the rear through hole 11 through needle guard 7 sidewalls of through hole 9 on the tube wall of tubule 4.

In the embodiment of Fig. 5, have protruding spacing ring 12 in the front inner wall of tubule 4, the thin tube part in spacing ring 12 front portions is divided into needle guard 7, and the front end of stitching thread 10 is connected with the rear end of sewing needle 8 through the through holes 13 in the middle of spacing ring 12 through tubule 4 is rear.

In the embodiment of Fig. 6, the front end of tubule 4 has needle guard 7, and the rear sleeve of sewing needle 8, in needle guard 7, has through wires hole 14 on sewing needle 8, and the front end of stitching thread 10 is rear through the through wires hole 14 on sewing needle 8 through the through hole 9 on the tube wall of tubule 4.

In the embodiment of Fig. 7, needle guard 7 is parts independently, be socketed in the front end inner chamber of tubule 4, by spiral connect, adhesive is bonding or welding manner is fixed on the front end of tubule 4, the rear sleeve of sewing needle 8 is in needle guard 7, and needle guard 7 sidewalls have through hole 11, and corresponding tubule tube wall has through hole 15, on the tube wall of tubule 4, separately have through hole 9, the front end of stitching thread 10 is connected with the rear end of sewing needle 8 through the rear through hole 11 through needle guard 7 sidewalls of through hole 9 on the tube wall of tubule 4.

In the embodiment of Fig. 8, needle guard 7 is outer surface cover one metal ferrules 16 of tubule 4 front portions, through metal ferrules, tightly push the cylindrical body of formation as needle guard 7, the rear sleeve of sewing needle 8 is in needle guard 7, on the tube wall of tubule 4, there is through hole 9, stitching thread 10 is through tubule 1, and after through hole 9 passes, its front end connects the rear end of sewing needle 8.
