Description

technical field [0001] The invention relates to a surgical instrument, in particular to a hair transplantation instrument. Background technique [0002] One of the best options for remedying hair loss is hair transplantation, which involves surgically obtaining hair from the patient's donor site, separating it and transplanting it to the area where the hair has been lost. The mechanism is the redistribution of the hair. In order to obtain a more natural appearance, at present, follicular unit transplantation is mostly used in the world. The traditional surgical instruments for hair transplantation are mainly perforated needles and medical tweezers, which are not only of poor quality but also of low efficiency. In order to solve the above technical problems, technicians have developed various hair transplantation devices, such as the invention patent with the notification number CN1192754C, which discloses a "hair transplanter", which includes a pen-shaped A hand-held devic...

AI Technical Summary

Problems solved by technology

The above-mentioned invention patent scheme can complete the punching and planting at one time, which has the advantages of convenience and quickness. However, since the needle described in it is similar to a common injection needle that is opened on one side and put into the hair root slot, the opening on it is put into the hair root slot. The socket of the hair root is very narrow, it is obviously difficult to put the hair follicles with the surrounding protective tissue in, and it is required to remove the protective tissue as much as possible before preparing the hair follicles. This will obviously affect the success rate of transplantation, and the difficulty of placing the hair follicles is also the same. It is predictable; in addition, when the needle penetrates the skin, the skin tissue will enter the needle hole through the slot, and it is also predictable to push the hair follicle upward.
