Controllable hole puncher of transplanting hairs of angle degree of depth of punching

Technical Field

The utility model relates to a controllable hole puncher of transplanting hair of angle degree of depth punches.

Background

The hair follicles of the human body are also transplantable like other tissues of the human body. The hair follicle transplantation widely adopted at present is micro-needle hair transplantation, a needle head is used for punching a planting hole on a planting area, and then forceps are used for planting the hair follicle obtained from the hair follicle. Referring to fig. 1, because a hand-held needle is used for pricking and drilling a planting hole, the needle inserting depth is very difficult to control and only can be controlled by the hand power of a person, and meanwhile, the same drilling depth at each time is difficult to ensure, so that the double problems of shallow depth and over-shallow depth of hair planting can be caused; meanwhile, the pricking angle is also influenced by the hand shaking amplitude and shaking angle each time because of no control and support of the gravity.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned defect or defect problems that exist among the prior art, the utility model provides a controllable hair planting hole puncher of the angle degree of depth of punching.

The technical scheme is as follows:
