Aseptic ultrasound knife handle protecting sleeve

Abstract

The invention discloses an aseptic ultrasound knife handle protecting sleeve which comprises an installing portion and a protecting portion. The back end face of the installing portion and the front end face of the protecting portion are fixedly connected and integrally formed, the bottom of the installing portion is provided with a clamping groove used for being clamped with the top of an ultrasound knife handle, the shape of the clamping groove is matched with that of the top of the ultrasound knife handle, and the protecting portion is provided with a containing channel used for allowing an ultrasound knife wire to pass. The aseptic ultrasound knife handle protecting sleeve has the advantages that the protecting sleeve can be installed on the ultrasound knife handle through the installing portion and can be completely clamped or bonded; connection between the wire and a knife head can be not influenced through the containing channel formed in the protecting portion, and meanwhile the protecting portion can prevent the knife head from being contaminated by the wire and well block bacteria; in addition, the protecting sleeve can expose out all operating buttons and a knife head rotating button which are arranged on the ultrasound knife handle, and therefore the ultrasound knife operating flexibility is not influenced.

Description

technical field [0001] The invention relates to the field of medical tools, in particular to a sterile protective cover for an ultrasonic handle. Background technique [0002] Ultrasonic knife is a medical tool. Its application principle is to convert electrical energy into mechanical energy through a special conversion device. After high-frequency ultrasonic vibration, the water in the contact tissue cells is vaporized, the hydrogen bond of the protein is broken, and the tissue is cut after being solidified. It has been widely used in the field of medical technology, especially in the application of laparoscopic surgery, which has obvious advantages. [0003] The existing ultrasonic scalpel is generally composed of three parts: the host, the cutter head and the wire. The host is used for external equipment and has no requirement for sterility, while the cutter head is used for one-time operation and has the requirement of sterility. There are many spare parts, but the wire ...

AI Technical Summary

Problems solved by technology

[0004] The current ultrasonic scalpel does not have a sterile protective cover. When in use, a simple sterile plastic film is bound to the cutter head, which is very inconvenient to use and seriously affects the button operation on the ultrasonic cutter head and the rotation of the cutter head. , which reduces the flexibility of the use of the cutter head, thus affecting the effect of the operation, and the effect of blocking bacteria is poor, and it is easy to contaminate the sterile field
