Abstract

The invention discloses a cricothyroid membrane incision suit which comprises a surgical knife blade, a knife stem and a pincers body, wherein a knife tip is arranged at the front end of the surgicalknife blade; and arc-shaped cutting edges are arranged on both sides of the surgical knife blade. The cricothyroid membrane incision suit is made of a metallic material and further comprises a structure inner layer and an antibacterial surface layer. As the antibacterial surface layer of specific constitution is formed on the surgical knife blade of the cricothyroid membrane incision suit, the cricothyroid membrane incision suit has a good antibacterial function, and particularly has a good antibacterial function on escherichia coli and staphylococcus aureus.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular, relates to a cricothyroidotomy device; more specifically, relates to a balloon pressure-indicating cricothyroidotomy set for cricothyrotomy ( or device). Background technique [0002] The cricothyroid membrane is located between the cricoid cartilage and the thyroid cartilage. It is a conical elastic fibrous connective tissue membrane and is a part of the elastic cone at the front of the laryngeal elastic membrane. The laryngeal elastic membrane is located in the deep surface of the laryngeal mucosa. It belongs to the connective tissue membrane containing elastic fibers. It is divided into upper and lower parts by the laryngeal chamber. The upper part is called the square membrane and the lower part is called the elastic cone. Initially, it attaches downward in a fan shape to the medial side of the upper edge of the cricoid cartilage. The anterior central part of the elas...
