Description

Disposable incision protection retractor

Technical Field

The utility model discloses a disposable incision protection retractor, in particular to the technical field of medical instruments.

Background

The incision protector is mainly used for expanding the operation visual field in the operation process, preventing the incision from being damaged, reducing the infection of the incision, effectively preventing the blood seepage of the incision tissue and reducing the postoperative wound pain and the blood stasis caused by excessive traction, and the incision protector is generally composed of an incision protection film and clamping rings respectively connected to the upper end and the lower end of the incision protection film, and the incision protection film forms an operation channel.

During surgery, the tissue is destroyed, ablated and decomposed using an electrosurgical instrument (ESU), laser scalpel, radio frequency scalpel or ultrasonic scalpel, resulting in fine particles suspended in the air, forming and emanating from the surgical channel as aerosol or burning smoke, i.e. surgical smoke. Surgical smoke is an air pollutant and can cause pm2.5 index near the operating table to reach over 300 (serious pollution level) when the concentration is high.

The existing method for avoiding the pollution of the operation smoke is mainly realized by using an electrotome with less coke smoke as much as possible and wearing a surgical mask, however, the common surgical mask can not effectively filter the operation smoke, and the smoke in the operation process is generally generated rapidly in a short time, so that the sight of a doctor is blocked, and the operation is influenced. In general, surgical smoke is not only a health hazard to medical personnel, but also is prone to interfere with surgery to some extent.
