Description

Closing knot pusher

Technical Field

The utility model relates to a surgical equipment especially relates to close and push away knot ware.

Background

The knot pusher is an instrument for assisting deep knotting in laparoscopic surgery. The laparoscopic surgery is different from the traditional open surgery, the surgical instruments can only enter the human body through a plurality of fixed channels, the operation is limited, and the knotting action difficulty which can be completed only by flexible operation of fingers in the open surgery is increased sharply.

The prior art also uses special equipment to assist in knotting, such as the following: 200920099229.x, it discloses deep assistor, the branching form of knot tying head on the knotter, and careless operation can make the knot break away from the knot tying head, and stability is poor.

SUMMERY OF THE UTILITY MODEL

The utility model provides a close knot pusher to the shortcoming of knotter poor stability among the prior art.

In order to solve the technical problem, the utility model discloses a following technical scheme can solve:

the closed knot pusher comprises a handle and a push rod, wherein the handle is fixedly connected with one end of the push rod; the other end of the push rod is provided with a through hole for the knotted wire to pass through, the through hole obliquely extends to the lateral surface of the outer cone of the push rod from the end surface of the push rod, the end part of the push rod is also provided with a wire guide groove for guiding the wire to extend out, two sides of the wire guide groove respectively penetrate through two sides of the push rod, and the through hole is communicated with the wire guide groove.

The complicated knotting action in the laparoscopic surgery is moved from the inside to the outside, so that doctors have more knotting schemes to choose. The knot pushes the knot into the body and tightens up through the through-hole that becomes inclination, pushes away the knot ware again with the knot, goes up and down and can not break away from the knot ware that pushes away in tightening up the in-process, and the stability of product is high.

Preferably, the side wall of the wire guide groove is an arc-shaped surface, and the through hole penetrates through the side wall of the wire guide groove and is communicated with the side wall. The wire guide groove plays a guiding role, so that the rope line can conveniently stretch out from the side edge of the rod body, and the wire guide groove of the arc-shaped surface can not obstruct the stretching out of the rope line.

Preferably, the ports at both ends of the through hole are tapered holes expanding outwards. The tapered hole prevents sharp corners from cutting the cord.

Preferably, the putter comprises a head and a shaft, the head being screwed or welded to the shaft. The connection between the club head and the club body is firm. The length of the threaded push rod can be adjusted, people only need to better rod heads, and the practicability is high.

Preferably, the shaft is a hollow tube, and the end of the club head extends into the shaft and is connected with the shaft by screw thread or welding. The rod body of the hollow tube has light weight, and is convenient for doctors to operate.

Preferably, one end of the handle is provided with a connecting hole, and the handle is in threaded connection or welded with the push rod through the connecting hole. The handle is firmly connected with the push rod.

Preferably, the handle is provided with anti-slip knurls on the side surface of the outer circumference.

The utility model discloses owing to adopted above technical scheme, have apparent technological effect:

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings 1-3 and examples.

Example 1

The closed knot pusher comprises a handle 1 and a push rod 2, wherein the handle 1 is fixedly connected with one end of the push rod 2; the other end of the push rod 2 is provided with a through hole 211 for passing a knotted wire, the through hole 211 extends from the end surface of the push rod 2 to the outer conical side surface of the push rod 2 in an inclined manner, and the two end ports of the through hole 211 are tapered holes 213 expanding outwards. The end of the push rod 2 is further provided with a wire guide groove 212 for guiding a wire to extend out, two sides of the wire guide groove 212 respectively penetrate through two sides of the push rod 2, the through hole 211 is communicated with the wire guide groove 212, the side wall of the wire guide groove 212 is an arc-shaped surface, and the through hole 211 penetrates through the side wall of the wire guide groove 212 and is communicated with the same. When in use, one end of the knot passes through the through hole 211 outside the body, the other end of the knot is knotted with the other end outside the body, and finally the knot is pushed into the body by the knot pusher and tightened.

The putter 2 is detachable, the putter 2 comprises a putter head 21 and a putter body 22, and the putter head 21 is in threaded connection with the putter body 22.
