Description

A retractor for maxillary surgery

Technical field:

The utility model relates to a pulling tool used in maxillary surgery, in particular to a retractor for maxillary surgery.

Background technique:

In otolaryngology, it is often necessary to perform maxillary surgery. During the operation, a traction hook is often required. First, the patient is anesthetized, and then the front end of the traction hook is inserted into the oral cavity to pull the mouth or the inside of the face, fully pulling one side of the oral cavity. Retraction, so that the doctor can easily take out the maxilla on the side of the mouth, and repair or treat the maxilla. In the process of using the traction hook, it takes a long time for the medical staff to hold the rear end of the traction hook by hand. , It is easy to cause the fatigue of the medical staff; in addition, the medical staff pulls the traction hook with their hands on one side, which easily hinders the operation of the surgeon and blocks the surgical field of view.

Invention content:

The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a retractor for maxillary surgery that is easy to use, does not require stretching by medical staff, does not hinder the operation of the surgeon, and can adjust the retraction angle.

In order to achieve the above object, the utility model provides a retractor for maxillary surgery, including a base, chute is symmetrically arranged on the front and rear end surfaces of the base, and sliders are symmetrically arranged on the left and right sides of the base, The lower ends on both sides of the slider are bent and respectively embedded in the chute on both sides, the outer middle part of the upper end surface of the slider is provided with a positioning bolt, and the inner middle part or rear end of the upper end surface of the slider is provided with a An arc-shaped support rod, the upper end of the support rod is connected with a retracting plate capable of swinging left and right through fastening bolts.

A sponge block made of elastic polyurethane sponge is arranged in the middle of the upper end surface of the base.

The lower end of the retractor plate is semicircular.

Suction cups may further be provided on the four corners of the lower end surface of the base.

The outstanding advantages of the utility model are: simple structure, when in use, the patient supports the head on the base or the sponge block on the base, anesthetizes the patient, and then moves the slide blocks on one side or both sides to the inside until the support The upper end of the rod is above the mouth corner on the corresponding side of the patient. Use the positioning bolts to position the slider, and then extend the retractor plate into the patient's mouth. After adjusting to a suitable angle, fix it by tightening the bolts. It is easy to use and not easy to use. The medical staff need to pull all the time, without hindering the operation of the surgeon, and the retraction angle can be adjusted conveniently, even during the operation, the angle can be adjusted conveniently; when only one side of the maxilla needs to be operated on , the slider on the other side can be moved to the outside by an appropriate distance or removed, avoiding the support rod and the retractor plate on the other side, hindering the smooth progress of the operation or obstructing the sight of the operation, etc., which is more convenient to use; the lower end of the retractor plate It is designed as a semicircle to avoid damage to the patient's oral cavity due to the existence of sharp corners after the retractor plate extends into the oral cavity.
