Description

Hair transplantation forceps

Technical Field

The invention relates to the technical field of medical instruments, in particular to hair transplantation forceps.

Background

The hair has the function of modifying the appearance of people, and is worried by more and more people caused by abnormal hair loss at present, but with the development of science and medicine, the problem of abnormal hair loss such as alopecia and the like can be solved through hair transplantation at present. Hair transplantation is a surgical method of taking a part of healthy hair follicle tissue and transplanting it artistically in a desired region of a patient according to the direction of hair growth. In the hair transplantation process, the tweezers play an irreplaceable role, and the processes of hair follicle extraction, separation and planting all need the participation of the tweezers. However, the conventional forceps used at present cannot well meet the requirement of hair follicle extraction and separation in the hair transplantation process, and have many disadvantages: in the follicular unit's of hair transplantation separation process, follicular unit's the little difficult separation of diameter to there are many tissues around the hair follicle, there is the condition of adhesion between the hair follicle, and traditional tweezers can not pinpoint and separate the hair follicle, easily destroys hair follicle structure and influences hair follicle planting effect and planting efficiency. Therefore, a new hair transplantation forceps needs to be designed.

Disclosure of Invention

The invention aims to solve the problems and designs hair transplantation forceps.

the hair transplantation forceps comprise forceps handles, forceps walls, forceps heads and positioning needles, wherein the forceps handles and the forceps walls are integrally connected and form a Y shape, and the positioning needles are installed on the forceps walls; the forceps walls comprise a first forceps wall and a second forceps wall, the width and the thickness of the tail end of the first forceps wall or the second forceps wall are gradually increased to form a contraction handle, a sliding groove is hollowed in the middle of the contraction handle, a sliding handle is installed in the sliding groove, the positioning needle is connected with the sliding handle, and the front end of the positioning needle extends to the forceps head and gradually declines; the forceps head comprises a first forceps head and a second forceps head, the first forceps head and the second forceps head are oppositely arranged at the tail ends of the first forceps wall and the second forceps wall, the first forceps head and the second forceps head gradually incline inwards from the connecting end of the first forceps head and the forceps wall to the tip end, the connecting end is horizontal to the forceps wall, and the tip end inclines downwards.

Furthermore, the connecting ends of the first forceps head and the second forceps head are cylindrical and round, the tips are wedge-shaped, the opposite sides are flattened, and the back and the opposite sides are round.

Furthermore, the width of the forceps head is 0.5-2mm, and the thickness of the forceps head is 0.2-1 mm.

Further, the sliding distance of the sliding groove is 5-6 mm.

Furthermore, a silica gel cap is arranged on the sliding handle.

Another object of the present invention is to provide a method for using hair transplantation forceps, which specifically comprises the following steps:

firstly, an operator clamps the first forceps wall and the second forceps wall by using a forefinger and a middle finger.

And step two, the operator enables the tip end of the forceps head to be aligned to the hair follicle under the microscope, and the forefinger and the middle finger apply force to the first forceps wall and the second forceps wall to clamp and extract the hair follicle.

Thirdly, an operator slides the positioning needle back and forth to position and adhere the tissues by operating the sliding handle with a thumb, presses and tightens the forceps wall, inserts the tip of the forceps head into the hair follicle adhesion area,

and step four, the operator loosens the forceps wall, then the adhesion area is slightly pulled open, at the moment, the right hand holds the scalpel blade, and the scalpel blade is inserted into and cuts the tissues between and around the hair follicles.

The invention has the beneficial effects that:

(1) the hair follicle transplanting device is easy to control and clamp hair follicles, facilitates twisting of the hair follicles in the hair follicle transplanting process, can stably clamp and extract the hair follicles, and improves hair transplanting efficiency. The forceps wall is wider, hands of a doctor can be easily clamped, the forceps are not prone to sliding in the using process, the stability of operation is guaranteed, the forceps head is narrower, the doctor cannot be shielded from operating under the microscope, and the hair follicle is not prone to being damaged due to the fact that the inner side of the tip of the forceps head is flattened.

(2) The hair follicle separation device is easy and convenient to separate and fix hair follicles, can accurately position the adhesion area of the hair follicles to separate the hair follicles, reduces the damage rate during hair follicle separation, and ensures the safety of the hair follicles. The tip of the forceps head is wedge-shaped, the width and the thickness of the forceps head are narrow, the forceps head can be inserted into a tissue area where hair follicles are adhered to prop open adjacent hair follicles, the positioning needle can position the adhesion area, and the forceps head is round and smooth, so that the surgical blade can slide downwards to cut and adjust the angle to separate follicular units.
