Description

Needle knife mirror

Technical Field

The invention relates to the technical field of traditional Chinese medicine minimally invasive, in particular to a needle knife mirror.

Background

The needle knife technique is also called small needle knife technique, which was created by the Zhu Hanzhang professor in the eighty years of the last century, and is one of the eight major minimally invasive techniques in traditional Chinese medicine at present. The needle knife is an operating tool used by the needle knife technology, the shape of the operating tool is similar to that of a tiny scalpel, the needle knife has a unique operating principle (debonding and stripping) for treating pain caused by soft tissue injury. It is popular with primary hospitals because of its simple, convenient and cheap features. Because the needle knife is small and exquisite, the diameter is about 1.0mm, when the needle knife is released and stripped, no operation incision is made, tissues are not fully exposed, the release and stripping are mainly carried out by depending on the experience of an operator, the small and exquisite advantage is the defect at the same time, safety accidents occur frequently, the release and stripping of the needle knife are carried out, focus searching is carried out by depending on the x-ray positioning, the ultrasonic positioning or the experience of the operator, the focus searching operation is called as 'blind operation', and the needle knife operation cannot know the focus property due to the incapability of direct vision, and the operation (release and stripping) cannot be thorough. For example, the tenosynovitis can not be completely released after the operation after the release, and the curative effect is greatly reduced. A greater range of debonding, such as a debonding of a herniated disc, is less reliable. The needle knife is a knife even smaller, and the blind operation of the needle knife is a dangerous behavior, so that medical accidents are inevitable.

Based on the above, the invention designs a needle knife mirror to solve the problems.
