Description

Inguinal hernia operation retractor

Technical Field

The utility model relates to the technical field of medical equipment, specifically indicate an inguinal hernia operation drag hook.

Background

Inguinal hernia refers to the protrusion of the visceral organs or tissues in the abdominal cavity of a patient, together with the parietal peritoneum, through the inguinal region toward the body surface. If the inguinal hernia is not treated in time, the hernia sac will gradually increase, resulting in damage to the abdominal wall and affecting work and life. Especially if the hernia is incarceration or narrowed, it may even be life threatening for the patient. Therefore, most inguinal hernia patients should be treated by operation in time.

However, the inguinal hernia surgery involves a small operation space and requires a good exposure to smoothly perform the hernia surgery. Most of hernia surgical instruments adopted at present are common thyroid retractor, blood vessel forceps and the like, and the operation process of the hernia surgical instruments usually needs medical care personnel to hold various instruments and can be completed only by mutual matching of more medical care personnel. Some existing draw hooks for hernia operations have many disadvantages although the problem of drawing operation is alleviated to a certain extent. For example, the existing retractor for hernia surgery generally includes a circular or oval bracket and a plurality of retractors movably arranged inside the bracket, when medical personnel perform hernia surgery, the bracket is fixed on an operating table through a bed clamp device, the bracket is made to correspond to the position of the surgical incision, and then the retractor is adjusted to prop open the surgical incision all around. Because the bracket is fixed by an additional bed clamp, on one hand, the bracket occupies the operation space of medical personnel, which leads to increased operation difficulty and prolonged operation time; on the other hand, too many instruments are used, and the operation preparation is complex, so that the working intensity of medical staff is increased, and the medical cost is correspondingly increased.

In order to solve the above problems, clinical medical care workers have tried to design an auxiliary surgical device that can effectively expand the surgical incision space, facilitate efficient and accurate operation, and further shorten the operation time of the inguinal hernia, but have not achieved satisfactory progress so far.
