Abstract

A slip knot-pusher capable of be threaded by a needle for celioscope operation suture and a suture needle used cooperatively with it belong to medical instrument technique domain. The slip knot-pusher includes a push rod and a side hole at the front terminal of the push rod, characterized in that the side hole is an arcate hole, the diameter of which is a little bigger than the diameter of the suture needle for the suture needle to thread through. The suture needle includes a needle and a suture thread connecting with the needle integrally, characterized in that the needle bends with a same radian as the radian of the side hole on the slip knot-pusher. The slip knot-pusher can be used conveniently for extracavity knotting and save the suture threads.

Description

Laparoscopic surgery is sewed up with knot pusher and the suture needle of can threading a needle

Technical field

This utility model belongs to medical apparatus and instruments.The suture instruments that uses in the laparoscopic surgery specifically.

Background technology

Peritoneoscope extensively adopts in gynecilogical operation.In the laparoscopic surgery operation, what be difficult to grasp most is suturing skill, the technology of particularly tiing a knot.The intracavity conventional sewing method of tiing a knot is: operative doctor has sutural suture needle to send into the abdominal cavity from handle hole with the needle forceps clamping, the assistant passes through another handle hole clamping suture needle to the appropriate location, suture tissue is tied a knot after suture needle penetrates and is extracted with needle forceps by the assistant more then.Its shortcoming is that complex operation, receipts knot are tight, haemostatic effect is poor.The straight pore of the front end side opening of the employed knot pusher of knotting for supplying stitching thread to penetrate outside the chamber, knotting can only be tied a knot at front end, so every line can only be sewed up a pin, the operation consumables cost is increased, add heavy patient's financial burden, intracavity knotting relatively, operation are easy to grasp, receipts are bolted, and haemostatic effect is good.

Summary of the invention

The purpose of this utility model provides a kind of improved laparoscopic surgery and sews up with knot pusher and the suture needle that matches with it and use, makes sew application simplify, sew up firmly, and can accomplish that single line can beat a plurality of knots.

This utility model is realized with following technical scheme: a kind of laparoscopic surgery is sewed up with the knot pusher of can threading a needle, it comprises the side opening of push rod and push rod front end, it is characterized in that side opening is an arcuation hole, the slightly larger in diameter in hole is advisable can pass sewing needle in the sewing needle diameter.

The described sewing needle that matches with knot pusher and use comprises syringe needle and links the stitching thread of one with syringe needle, it is characterized in that syringe needle be with knot pusher on the bending of side opening identical radian measure.

Owing to adopted technique scheme, can realize easily tiing a knot outside the chamber, not only simplified control but also stitching are firm, and haemostatic effect is good.Because knot is beaten online afterbody, single line can be sewed up spininess, saves patient's expenditure.

Description of drawings

Further specify structure of the present utility model and using method below in conjunction with drawings and Examples.

Fig. 1 is the knot pusher structural representation;

Fig. 2 is the sewing needle sketch map;

Fig. 3 is knot pusher and the sewing needle structural representation when being used;

Fig. 4 forms the Slipped Clove Hitch sketch map outside the chamber;

Fig. 5 is to use knot pusher that Slipped Clove Hitch is pushed the intracavity sketch map.

The specific embodiment

As shown in Figure 1, knot pusher comprises push rod 1, at the front end of push rod 1 arc side opening 2 is arranged.

As shown in Figure 2, sewing needle comprises syringe needle 3 and the stitching thread 4 that is connected the syringe needle tail end, and syringe needle is an arc-shaped bend shape, and radian is identical with arc side opening 2 radians of knot pusher.

As shown in Figure 3, be advisable can just pass syringe needle 3 in the aperture of knot pusher upper-side hole 2.

Concrete using method is:

1, with holding device pin is sent into the abdominal cavity;

2, sew up the wound chamber;

3, clamping the Aculeata line with needle holder takes pin outside the abdominal cavity out of;

4, as shown in Figure 3 pin is passed from the knot pusher side opening;

5, outside the chamber, form Slipped Clove Hitch as shown in Figure 4;

6, with knot pusher Slipped Clove Hitch is pushed intraperitoneal as shown in Figure 5;

7, carrying out next pin sews up.

Because of each afterbody that is line that uses, so form neat firm interrupted suture.

Claims

1, a kind of laparoscopic surgery is sewed up with the knot pusher of can threading a needle, and it comprises the side opening of push rod and push rod front end, it is characterized in that side opening is an arcuation hole, and the diameter in hole is advisable can pass sewing needle greater than the sewing needle diameter.

2, a kind of sewing needle that matches with the described knot pusher of claim 1 and use comprises syringe needle and links the stitching thread of one with syringe needle, it is characterized in that syringe needle be shaped as with knot pusher on the bending of side opening identical radian measure.
