Abstract

The utility model provides a laparoscope knot pusher which comprises a push rod and a knot pushing head disposed at the front end of the push rod. A suture groove for placing a suture is arranged at the top of the knot pushing head. A plurality of suture holes allowing two ends of a suture to penetrate are arranged on the push rod, and the suture holes correspond to ends of the suture groove. By the suture holes arranged on the push rod, the suture can penetrate through the suture holes, an operator can pull the suture lightly during pushing of the push rod, sliding down of the suture from the top of the knot pushing head is avoided, and laparoscope knotting efficiency is increased.

Description

The peritoneoscope knot pusher

Technical field

This utility model relates to a kind of peritoneoscope medical apparatus and instruments, particularly relates to a kind of peritoneoscope knot pusher.

Background technology

In human body Wicresoft laparoscopic procedures, the otch of people's in-vivo tissue organ pipe need be sewed up, and in sewing process, stitching thread needs knotting, in order to guarantee the stable and firm of in-vivo tissue organ pipe otch, needs stitching thread is tightened in the knotting process.Be generally external will knot to accomplish fluently then promote this with knot pusher and knot it is pricked into, but knot pusher commonly used in use is prone to suture from its top landing at present, causes knotting slowly.

China ZL201020206294 discloses a kind of operation with sewing up knot pusher, it is made up of handle, device bar and device head, described device bar is rod-like structure, the front portion of described device head is the flat structure, the procephalic flat structure of this device place has a circular arc type groove, described handle is fixed on an end of device bar, and described device head is fixed on the other end of device bar.

Therefore, shortage is a kind of guarantees that suture can't be from the knot pusher of top landing.

The utility model content

The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of peritoneoscope knot pusher, is used for solving the prior art knot pusher problem that comes off from its top easily of suture in use.

Reach other relevant purposes for achieving the above object, this utility model provides a kind of peritoneoscope knot pusher, the knot head that it comprises push rod and is located at the push rod front end, the top of described knot head is provided with the wire casing of placing suture, described push rod is provided with four through wires holes that supply suture two to pass, and described through wires hole is corresponding with the end of described wire casing.

Preferably, described push rod is round tube, and the external diameter of push rod is 5mm～10mm.

Preferably, the length of described push rod is 35cm～50cm.

Preferably, described knot head is flat trapezium structure, and the end size that the knot head links to each other with described push rod is less than knot head size.

Preferably, the top of described knot head is provided with the groove that intersects with described wire casing.

As mentioned above, peritoneoscope knot pusher of the present utility model, have following beneficial effect: it adopts at push rod through wires hole is set, suture therefrom passes like this, operator spurred suture gently when push rod advanced, and can avoid suture from the landing of knot head, had improved the efficient of tiing a knot under the peritoneoscope.

The specific embodiment

Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this description.

See also Fig. 1 to Fig. 2.Notice, the appended graphic structure that illustrates of this description, ratio, size etc., equal contents in order to cooperate description to disclose only, understand and reading for person skilled in the art scholar, be not in order to limit the enforceable qualifications of this utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not influencing under the effect that this utility model can produce and the purpose that can reach, all should still drop on the technology contents that this utility model discloses and get in the scope that can contain.Simultaneously, quote in this description as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, under no essence change technology contents, when also being considered as the enforceable category of this utility model.

As shown in Figure 1, this utility model provides a kind of peritoneoscope knot pusher, the knot head 2 that it comprises push rod 1 and is located at the push rod front end, the top of knot head 2 is provided with the wire casing 4 of placing suture, push rod is provided with four through wires holes 3 that supply suture two to pass, and through wires hole 3 is corresponding with the end of described wire casing 4.This utility model adopts and at push rod through wires hole to be set, and it can pass for suture, and when knot pusher promoted forward, the operator can gently draw suture two, can avoid suture landing in the wire casing like this, has improved the efficient of tiing a knot under the peritoneoscope.

Be convenient to laparoscopic surgery and use, above-mentioned push rod 1 is round tube, and the external diameter of push rod 1 is 5mm～10mm, and the length of push rod 1 is 35cm～50cm.

Above-mentioned knot head 2 is flat trapezium structure, and the end size that knot head 2 links to each other with push rod 1 like this can be so that the both sides of suture applying knot head be convenient to knotting more less than knot head size.

As shown in Figure 2, the top of above-mentioned knot head 2 is provided with the groove 5 that intersects with wire casing 4, and this groove is arcuate groove, it can be used as separated part, and two of the suture that knots is in respectively in the above-mentioned wire casing 4, is in the groove and knot, be convenient to exert all one's strength, improve the efficient of tiing a knot under the peritoneoscope.

In sum, peritoneoscope knot pusher of the present utility model, it adopts at push rod through wires hole is set, and it can pass for suture, and when knot pusher promoted forward, the operator can gently draw suture two, can avoid suture landing in the wire casing like this, had improved knotting efficient.So this utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.

Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction this utility model.Any person skilled in the art scholar all can be under spirit of the present utility model and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that this utility model discloses and the technological thought, must be contained by claim of the present utility model.
