A cut protector adapted to small cuts

Abstract

The invention discloses a cut protector adapted to a small cut. The cut protector is characterized by comprising a film sleeve pipe for forming a surgery channel, an outer ring arranged at the top ofthe film sleeve pipe and a placing ring arranged at the bottom of the film sleeve pipe, wherein a hollow cavity is formed in the placing ring; a metal wire for strutting the caliber of the placing ring is arranged on the inner wall of the placing ring; a mounting block is arranged at one end of the metal wire, and is fixedly arranged on the inner wall of the placing ring; a through hole is formedin the mounting block; the metal wire penetrates through the through hole; the mounting block is connected with the metal wire in a sleeving manner to form a movable annular ring; an accommodating cavity is formed in the film sleeve pipe, and penetrates through the hollow cavity of the placing ring; the other end of the metal wire enters the outer ring through the accommodating cavity; a winding assembly is arranged on the outer ring; one end which extends into the outer ring, of the metal wire is connected to the winding assembly; and the winding assembly is used for adjusting the diameter ofthe annular ring. The cut protector disclosed by the invention has the beneficial effects that the size of the caliber of the placing ring is convenient to adjust, so that the placing ring can conveniently extend into the cut and can be conveniently taken out.

Description

technical field [0001] The present invention relates to an incision protector, more specifically relates to an incision protector adapted to small incisions. Background technique [0002] In a surgical laparotomy, when the doctor cuts open the patient's surgical site, the incision is closed due to tissue contraction. In the past, doctors used metal retractors or hooks to open the incision after incision of the patient's skin, so as to expose the surgical field of view. However, excessive retraction often caused tearing of the wound or insufficient exposure angle. At present, various incision protectors have been developed for clinical application, usually an outer ring, an insertion ring and a sleeve-shaped film between the two. At this stage, the inserting ring of the incision protector is inserted into the incision, and the outer ring stays outside the body, so as to achieve the purpose of opening the incision. The doctor can perform surgery on the patient in the surgical...

AI Technical Summary

Problems solved by technology

However, the size of the insertion ring of the existing incision protector is fixed, and the diameter of the insertion ring cannot be adjusted. In some operations with small incisions, it is necessary to press the insertion ring so that the insertion ring shrinks and then put into the incision In the case of improper operation, the incision is easy to be pulled, which increases the opening area of ​​the incision and increases the wound healing time of the patient; at the same time, at the end of the small incision operation, it is difficult to remove the inserted ring because it is difficult to deform.
