Description
Technical field
The utility model belongs to medical instruments field, is related to a kind of small needle knife, in particular to a kind of to have nerve stimulation function
The small needle knife of energy.
Background technique
It is much smaller that the cutter hub of small needle knife is compared to surgical knife, has that wound is small, heal, effect is good, concurrent
The features such as disease is few.Currently, small needle knife is commonly used to clinical medicine, it is common to use needle knife structure it is simple, by needle handle, solid needle body
It is constituted with pancake needle cutting edge of a knife or a sword three parts, is usually used in the closeds such as absent-mindedness, the neural absent-mindedness with soft tissue adhesion of soft tissue adhesion
Operation.In clinical application, hospital staff usually faces three problems when performing the operation: 1. preoperative to be correctly found nerve
Position；2. being allowed in art between small needle knife cutter head and nerve and remaining suitable distance；3. in needle knife therapeutic process, needing controlling
When treating partial syringe drug increase curative effect, it is often necessary in addition can be injected with injection needle-penetration rear.
In view of the above-mentioned problems, people devise various small needle knifes, inside and outside two layers of the small needle knife having also may be implemented to infuse in art
Problem is penetrated, the problem of also neuroprobe may be implemented in some nerve stimulation instrument, but designed reasonably without a kind of small needle knife
