Description

Medical surgical deep double knot knotter

technical field

The utility model relates to a knotter for medical operation, in particular to a deep double-knot knotter for medical operation.

Background technique

Knot tying is a very important technique in surgical operations. Intraoperative hemostasis and suturing are inseparable from ligation. It can be said that knotting runs through the entire process of surgical operations. Whether the ligation is firm and reliable is closely related to the method of knotting, auxiliary equipment, and proficiency. The speed and quality of knotting are not only related to the length of operation time, but also affect the quality of the entire operation and the patient's postoperative recovery.

The knotting methods of traditional surgical deep surgical sutures are basically divided into two types: manual knotting and forceps knotting. Due to the small field of vision and deep position, the fingers cannot enter the position that needs to be tied due to the manual knotting. Although holding the forceps to tie a knot can enter the position that needs to be ligated, it is easy to make the knot slip off, thereby affecting the smooth progress of the operation.

Chinese utility model patent (CN 2349992Y) discloses a medical surgical knotter, which is composed of a rod body, a handle, a knotting head, and an arc groove; the front end of the rod body is a knotting head, and the knotting The front end of the head has an arc-shaped groove, the rear end of the rod body is a handle, the knotting head is a smooth hemisphere, and the inner wall of the arc-shaped groove is a smooth surface. When using the above-mentioned medical surgical knotter to tie a knot, the operator first knots the suture thread, then holds one end of the suture thread with both hands and lifts it up. Hold the knot in the groove and slide it toward the ligation site until the suture is tied. The utility model has the advantages of simple structure and convenient knotting.

Chinese Utility Model Patent (CN204428093U) discloses a medical surgical knotter, comprising: a rod body, a handle disposed at the proximal end of the rod body, and a knotting head disposed at the distal end of the rod body, wherein the knotted The front end of the head is provided with a U-shaped hook opening towards the far end of the rod body. The medical surgical knotter is equipped with a U-shaped hook with an opening facing the distal end of the rod body at the front end of the knotting head, so that the surrounding tissue will not be accidentally damaged during the knot pushing process, the safety factor is high, and the suture thread is not easy to fall off. Moreover, the knotting head and the rod body of the medical surgical knotter form an obtuse angle structure, so that no restrictions are imposed on the knot pushing angle and the knot pushing direction during the knotting process.

However, the above-mentioned medical operation knotter can only tie one knot at a time, and the suture thread of the first knot is easy to slip off during the process of making the second knot.

Contents of the invention

Aiming at the deficiencies of the prior art, the utility model provides a deep double-knot knotter for medical surgery with simple structure, convenient operation, accurate and fast knotting, and the knotted knot is not easy to fall off, which effectively solves the problem of deep surgery in surgery. The problem of suture knot slipping off.

In order to achieve the above object, the technical solution adopted by the utility model is:

The deep double-knot knotter for medical operation includes a guide rod, a push rod and a spring;

The guide rod is a hollow structure, the rear part of the guide rod is provided with an A handle, the rear end of the A handle is provided with an A protrusion along the axial direction of the guide rod, and the front end of the guide rod is provided with a sliding section, the radial section of the sliding section is the guide rod passing through the shaft. In the part below the heart level, the front part of the sliding section is provided with an A push line end;

The push rod is of solid structure and the inner diameter matches the outer diameter of the guide rod. There is a B handle at the rear of the push rod. The front end of the B handle is provided with a B protrusion along the axial direction of the guide rod. push line end;

The push rod is sleeved on the guide rod, a spring is set between the A protrusion and the B protrusion, and the spring is sleeved on the A protrusion and the B protrusion, and the push wire end moves along the axis of the guide rod in the sliding section;

The distance between the A protrusion and the B protrusion is greater than the length of the sliding section;

The wire-pushing end A and the wire-pushing end B are provided with fixing arcs.

The A protrusion and the B protrusion are circular and have the same outer diameter.

When in use, the surgeon first makes the first knot of the suture that needs to be tied, and places the knotted center on the thread-fixing arc of the deep double-knot knotter A for medical surgery, and then makes the second knot. Put a knot and place the knotted center on the fixed line arc of the push line end of B. Hold the handle A with your hand and push it forward. Push forward, and the suture will come out from the thread-fixing arc at the thread-pushing end of A and be pushed forward by the thread-fixing arc at the thread-pushing end of B. When it can’t be pushed, the second knot has been tied at the position of the first knot, and exit Medical operation deep double knot knotter, at this time there are two knots on the suture, which is not easy to slip off.

The beneficial effects of the utility model:

1. The utility model has the advantages of simple structure, convenient operation, accurate and fast knotting, and the knotted knot is not easy to fall off.

2. The utility model adopts the A protrusion, the B protrusion and the spring between them to connect the guide rod and the push rod together, which is convenient to control the moving distance of the push rod relative to the guide rod and the reset after the operation of the guide rod and the push rod .

3. The utility model adopts the thread-pushing end A and the thread-pushing end B. When the push rod moves relative to the guide rod, the second knot can be moved forward conveniently, and the suture is easy to come out from the thread-pushing end A.
