Description

An adjustable disc-shaped surgical retractor

technical field

The utility model relates to medical equipment, in particular to an adjustable disc-shaped surgical hook.

Background technique

In surgery, after the skin and muscle are cut, the surgical field of view is poor due to the contraction of the skin, muscle and adjacent tissues. This requires pulling the skin, muscle and adjacent tissues to the surrounding area to broaden the surgical field of view. Effectively expose the surgical target and facilitate the surgical operation.

At present, the traditional metal retractor widely used in clinical practice requires multiple people to use multiple retractors from different angles at the same time. There are generally three problems with traditional retractors: First, the effect is unstable: when using multiple retractors, due to uneven force, it is easy to shake, which seriously affects the smooth operation of the operation, and even causes the operation to fail; second, the effective operation space is reduced: multiple The use of retractors at the same time occupies the effective space of the operation, affects the doctor's surgical field of vision, and brings inconvenience to the doctor's operation; the third is to increase the doctor's load: the simultaneous use of multiple retractors increases the doctor's surgical load and limits part of the doctor's work. Increased difficulty in performing quality surgery. Generally speaking, this kind of traditional retractor increases the workload of medical staff, the efficiency of fixing the incision is low, the effect is unstable, and affects the progress of the operation; it cannot be folded, and the curved parts such as the perineum cannot perfectly fit the human body, and the retractor cannot be adjusted at will Stretch strength and length.

Aiming at the defects of the prior art, the utility model provides an adjustable disc-shaped surgical retractor, which can effectively solve the above-mentioned problems in the prior art.

In order to realize above utility model purpose, the technical scheme that the utility model takes is as follows:

An adjustable disc-shaped surgical retractor, comprising a disc-shaped support and a retractor;

The disc-shaped support is oval or circular and consists of two semicircular hinges; the outer frame of the support is provided with a number of fixing grooves surrounding the support for fixing the pull hook;

The hinge of the disc-shaped bracket can be folded, and there is also a limit knob for fixing the folding angle;

The draw hook is composed of a hook head, a hook handle and a hook body. The upper part of the hook handle is connected to the hook head, and the lower part is connected to the hook body. The hook body is provided with a number of locking teeth, which are used to cooperate with the groove of the disc-shaped bracket to fix the draw hook and adjust The length of the hook body when the hook is in use.

Preferably, the hook body is in the shape of a soft plastic strip with a diameter of 5mm.

Preferably, the shape of the hook head is 1/2 circle, the diameter of the circle is 5-10 mm, and it is made of high-strength stainless steel alloy.

Preferably, the hook handle is made of high-strength polyurethane.

Preferably, the maximum folding angle of the disc-shaped support is 180°.

Preferably, the distance between the grooves of the disc-shaped support is 1-2CM.

Compared with the prior art, the utility model has the advantages of:

1. The shape-adjustable disc-shaped retractor bracket can effectively stabilize the retractor, and at the same time increase or decrease the number of retractors according to the needs of the operation;

2. The effective length of the retractor can be precisely adjusted, and the exposed area of the surgical wound can be adjusted according to the surgical needs;

3. The retractor bracket is equipped with a limit knob. It is oval or circular when laid flat, but the shape of the bracket can be adjusted according to the surgical site. It is suitable for surgical operations on most superficial parts of the body, especially for perineal surgery. traction;

4. The retractor is made of polyurethane, and the disc-shaped bracket and node-shaped retractor are disposable, which reduces the risk of infection caused by repeated disinfection and is more convenient to use;

5. The size design of the equipment is reasonable, suitable for surgical use.
