Ultrasonic bone knife head

Abstract

The invention discloses an ultrasonic bone knife head. The ultrasonic bone knife head comprises a cutting part located at the front end of the ultrasonic bone knife head, a knife tail connected with a transducer, and a knife rod for connecting the cutting part and the knife tail, the cutting part is in the shape of a long cylinder, the end of the cutting part is folded, and side surfaces of the cylinder are provided with a plurality of spiral-shaped blades. During operation by using the ultrasonic bone knife head, the knife head does not rotate so that the body tissue can be prevented from dangers such as rolling, twisting, traction etc. According to the ultrasonic bone knife head, the positioning is accurate, phenomena of slip and deviation on the bone surface can be prevented, the cutting process is smooth, and the controllability is high. The ultrasonic bone knife head can be used for grinding, drilling, scraping, trimming, and the like. The ultrasonic bone knife head has the drilling function and the grinding function in an integrated manner, thereby realizing multiple purposes of one knife, saving the operation time and reducing the fatigue of surgeons.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a scalpel, in particular to an ultrasonic bone knife head. Background technique [0002] In modern society, with the development of medical technology, orthopedic surgery presents a trend of diversification. Correspondingly, when performing surgery, it is necessary to use different shapes of surgical blades to cut, grind, scrape, Clamping and other operations. [0003] In orthopedic surgery, it is often necessary to grind and drill the bones. Air drills or electric drills are usually used to cut bone tissue by using its high-speed rotation characteristics to achieve the purpose of grinding and drilling. In practical application, on the one hand, the high-speed rotation of the drill bit will cause twisting and pulling hazards to the surrounding blood vessels, nerves and other tissue structures that need to be protected, which will cause fatal damage to the patient and lead to the...

AI Technical Summary

Problems solved by technology

In practical application, on the one hand, the high-speed rotation of the drill bit will cause twisting and pulling hazards to the surrounding blood vessels, nerves and other tissue structures that need to be protected, which will cause fatal damage to the patient and lead to the failure of the operation.

On the other hand, the high-speed rotating drill bit will vibrate when it contacts the body tissue, and it is easy to deviate from the designated position, that is, the operation process is not stable enough, and slipping and deviation will occur

Injury to other non-surgical parts, causing danger

This puts forward higher requirements on the operation level of medical staff, increases the physical and mental pressure of doctors, reduces the success rate of surgery, and increases the risk of surgery for patients
