Surgical scalpel facilitating wound expansion

Abstract

The invention discloses a surgical scalpel facilitating wound expansion, and relates to the field of medical instruments.The surgical scalpel facilitating wound expansion comprises a scalpel back and a scalpel edge, the scalpel back is fixedly installed on the top wall face of the scalpel edge, the interiors of the scalpel back and the scalpel edge are hollow, and the interiors of the scalpel back and the scalpel edge communicate with each other; according to the surgical scalpel convenient for expanding the wound, the rubber sleeve is pressed by the thumb of a doctor, so that the rubber sleeve extrudes the internal area of the auxiliary handle, and the internal area of the auxiliary handle is extruded by the rubber sleeve, so that the internal area of the auxiliary handle is expanded; air pressure is conducted and transmitted into the expansion block and the adjusting block through the connecting block, the auxiliary handle, the knife back and the knife edge, so that the expansion block is extruded by the pressure to be curled and expanded, the wound of a patient is expanded from inside to outside, and the movement range of the scalpel in the wound is increased; therefore, the surgical precision and convenience are improved, and wounds can be effectively and deeply cleaned.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a surgical scalpel which is convenient for expanding wounds. Background technique [0002] A scalpel is a commonly used instrument in large and small treatment operations. It usually mainly performs operations such as cutting, excision, and cleaning on patients. When using a scalpel to treat a patient's wound, it is usually based on the patient's condition. The wound is opened to different degrees, and the method of opening is often carried out with surgical forceps from the outside to the inside. This method usually causes the inner end of the wound to be too narrow to complete effective cleaning. The way of propping up can easily lead to tearing of the outside of the wound, resulting in unnecessary secondary injury and wound infection. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a surgical scalpel that is convenient for expanding wo...

[0002] Scalpel is a commonly used instrument in large and small therapeutic operations. Usually, it mainly performs operations such as dissection, resection, and cleaning on patients. The wound is stretched to varying degrees, and surgical forceps are often used to prop up the wound from the outside to the inside. This method usually makes the inner end of the wound too narrow to complete effective cleaning. The way of propping up can easily cause the outer side of the wound to tear, thus causing unnecessary secondary injury and wound infection
