The small needle knife is applicable to hair transplantation and particularly to fine operation of punching in a reception area in high-density hair transplantation, so that the purposes of improving transplantation density, transplantation efficiency and transplantation survival rate, and relieving pain of patients are achieved.

Description

technical field [0001] The invention relates to a punching device for hair transplantation, in particular to a punching device suitable for superfine, individualized and high-density hair transplantation in the hair transplantation process. Background technique [0002] At present, the FUT technique in plastic surgery (i.e., follicular unit transplantation) uses special surgical perforating instruments to perforate the skin of the recipient area during the hair transplantation process, thereby providing the transplantation site of the follicular unit, and has certain advantages. Pore ​​size and depth, without damaging the transplanted follicular unit, can finally make the follicular unit grow smoothly. The most common punching knives used for hair transplantation are 21G or 22G ordinary injection needles, various types of gem knives, various single-edged and double-edged knives, and KNU hair transplanters. Such perforating instruments cannot effectively control the perforat...

AI Technical Summary

Problems solved by technology

This kind of punching instrument cannot effectively control the punching depth, nor can it provide the implant with a harmonious and consistent exit angle with the surrounding hair in special parts

At the same time, due to the fixed width of the punching instrument and the large hole diameter, the punching density is limited, causing excessive damage to the skin and blood vessels, and it is impossible to match the hole diameter of a single hair transplant or a double or more hair transplant.

It brings difficulties to the individualized and refined operation of hair transplantation, especially high-density hair transplantation
