Problems solved by technology

Although the soft retractor will not cause any compressive damage to the tissue on the opening surface of the incision, the supporting force is fixed on the skin of the incision by the four cloth strips around the metal ring. Due to the limitation of the width of the cloth strips, the two The incision tissue area betw...

Abstract

The invention provides a retractor. The retractor comprises a cylindrical film made of flexible material, an upper ring located at the opening of the upper portion of the cylindrical film and made of flexible material, and a lower ring located at the opening of the lower portion of the cylindrical film and made of flexible material. The lower ring is a hollow pipe. An alloy wire is arranged in the hollow pipe. The upper ring is of a dual-pipe structure. The dual-pipe structure comprises a first branch pipe and a second branch pipe which are vertically connected in parallel. An alloy wire is arranged in at least one of the first branch pipe and the second branch pipe. By means of the retractor, no constrictive injuries can be caused to tissue of an incision retracted face, the protection and hemostasis functions are achieved for incision tissue, incision tissue can be isolated and protected in a sealed mode when an incision is retracted, and cross infection probably caused during surgery is avoided.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a retractor for retracting tissue, exposing the operating field of view, and facilitating exploration and operation. Background technique [0002] Retractors are surgical instruments used to retract tissue to expose the surgical field of view for easy exploration and manipulation. Commonly used metal retractors and soft retractors. The disadvantages of metal retractors are that the shape is fixed, the wound is large, and the compressive damage to the tissue is relatively large, such as periosteum injury and bone nerve injury. On the other hand, due to the limitation of its shape, it will block the surgical field of view to a certain extent and affect the surgical operation. And soft retractor can't carry out hermetic isolation protection to incision tissue. [0003] The soft retractor in the prior art has an elastic ring placed in the incision, and can be very well adapted to surgical ...
