Description

Suture knot pusher

Technical Field

The utility model belongs to the technical field of minimally invasive surgical instruments, and particularly relates to a suturing knot pusher.

Background

Knotting is one of the most basic techniques of surgery, mainly including locking knots and suturing knots. Regardless of the size of the operation, whether the operation is correct or not, how the skill level is, etc., not only represents the basic quality of the surgeon, but also directly relates to the effect of the operation and even to the safety of the patient.

Minimally invasive surgery is a new technique for performing surgery in a human body through endoscopes such as laparoscopes, thoracoscopes and the like. Minimally invasive surgery has the advantages of small trauma, light pain and quick recovery. At the same time, a new requirement is put on the traditional surgical technical means of surgical suturing: suturing and knotting is required under minimally invasive conditions. The existing knotting technology is basically finished by manual winding, the knotter has the additional function of auxiliary knotting, the defects of high trouble and labor consumption of knotting and excessive knotting effect and success rate depend on the proficiency of operators, but the knotting effect and success rate are extremely small for endoscopic minimally invasive surgery and wounds, the traditional manual knotting method is not feasible, and the knotting device is used for ligating the knotted part with extremely high knotting risk.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: the utility model provides a suture knot pusher, including the knot pusher handle that pushes away that connects gradually, push away knot ware pole and knot ware head, push away knot ware handle and include handle shell, lock sleeve and slider, push away knot ware pole and be double-deck stainless steel tube structure, including inside interior pole and outside wrapped outer pole, the outer pole can slide along the interior pole, inside the interior pole is fixed in the handle, the outer pole passes through bow member embedding knot pusher handle in, the one end that the outer pole stretched into in pushing away knot ware handle is connected with the slider, knot ware head is hollow structure, knot ware head is the end portion of outer pole and interior pole, the last blade of seting up of knot ware.

Further, one end of the bow-shaped piece extending into the handle of the knot pusher is sleeved with a spring, one end of the spring is limited through the rear end of the bow-shaped piece, and the other end of the spring is limited through a locking sleeve.

Further, the structure of the knot pusher head is a cylinder, the hollow part at the front end of the knot pusher head is a suture inlet, and the cutting edge is a suture outlet.

Further, the joint of the knot pusher head and the knot pusher rod is of a flexible structure.

In summary, the utility model has the following advantages:

1. the utility model has simple structure and convenient operation, and can realize the integration of knot pushing and thread cutting and reduce the use of instruments for minimally invasive surgery requiring suture treatment and knotting treatment. In the structure disclosed by the utility model, the joint of the knot pusher head and the knot pusher rod is of a flexible structure, which is equivalent to the bendable use of the knot pusher head, and has better application prospect in suture knot pushing with hidden cavities.
