Description
Technical Field
The invention relates to a hair follicle implanting instrument with a hair sucking component.
Background
With the development of society and the increase of consumption level, the working pressure of people is gradually increased, the phenomenon of alopecia is increasingly aggravated, and the trend is towards the youth. The alopecia is not only damage to the appearance of the human body, but also is a self-confident attack and rather a depreciation to the spirit of the human body.
The current primary mode of treating hair loss is hair transplantation: generally, hair follicles in the hindbrain region of a human body are taken as a hair source, and are separated into single or multiple follicular units, and the follicular units are transplanted to a region to be transplanted, such as a head, an eyebrow, eyelashes, beard, a chest, an eyelash, a pudendum and the like, through a fine microsurgery technology, so that the follicular units can survive and naturally grow on a new region, and the purpose of repairing the local hair distribution density is achieved, and the beautiful effect is achieved.
At the present stage, in the hair follicle implantation instrument, namely, in the hair transplantation process of the hair transplantation needle, most commonly, the hair follicle is arranged in a needle tip part by tweezers in advance, and then the hair follicle is implanted under the skin through the ejection core rod. For example, in patent nos. 201210364166.2, 200620012559.7, 201120001190.0, 201220589387.5, 00801606.2 and the like, the most complicated and tedious part of the operation process is to load the hair follicle into the needle tip part, because the inner diameter of the needle tube is small and the needle tube needs to be placed at a certain depth, the hair follicle is easily damaged in the process of clamping the hair follicle by using forceps, so that the hair follicle is dead, great patience is needed in the loading process, time and labor are wasted, the loading direction and depth cannot be effectively controlled, and the success rate of transplantation is greatly reduced by the loading mode.
In addition, patent No. 200910040545.4 discloses a hair transplantation device, in which the front half section of the planting needle is in the shape of slightly-opened forceps, a semicircular groove is arranged at the inner side of each half forceps, when the hair follicle is loaded, the two half forceps can be opened naturally by using a control sleeve, and then the hair follicle is loaded into the planting needle. The loading principle of the device is that the loading needle tip opening is enlarged, so that hair follicles can be easily loaded and completed, the method has a few defects, if hair follicles need to be clamped by tweezers during loading, the hair follicles are easily damaged, the needle tip is in a conical shape after being closed, the patient can generate huge pain due to large puncture force during punching, the hair is loaded into the planting needle after being closed, the direction of the planted hair is not consistent, the appearance is attractive, the front end of the planting needle opens to extrude skin flesh to cause secondary pain to the patient after the hair follicles are implanted under the skin, and the whole planting needle can cause tertiary pain to the patient when moving away from the skin. Structurally, the implantation depth of this transplantation apparatus is not adjustable, because different patients ' hair follicle depth is different, therefore this apparatus can't be applicable to different patients, adopts the form of two spring secondary compressions to influence doctor's operation and feels in addition, brings the inconvenience for the operation.
Patent No. 200410076693.9 discloses a method and apparatus for hair transplant, which has the advantages that hair transplant can be placed in the hair transplant cavity manually or mechanically (such as by vacuum), so as to effectively avoid damage to hair follicle by physical force, the success rate of planting is greatly improved but the apparatus does not have the function of punching, there is a great defect in function, the hair follicle needs to be implanted under the skin by using the apparatus after punching holes in advance by using an apparatus such as punching needle, various apparatuses are needed during the execution, the operation is complicated and inconvenient, and the planting speed is affected.
TWM452746U1 provides a hair follicle implanting apparatus comprising an outer tube and an inner tube, which function when the inner tube is in a retracted position, the inner tube is located within the outer tube and is evacuated from the air passage through the air valve to maintain the hair follicle within the tube, and when the inner tube is moved from the retracted position to an advanced position, the inner tube projects outwardly from the outer tube and is inflated from the air valve to the air passage to push the hair follicle out of the outer tube for subcutaneous implantation. The instrument has the advantages that the hair follicle is maintained in the needle tube in a negative pressure mode and is pushed out by air pressure when being implanted, so that the damage of human mechanical force to the hair follicle is effectively reduced, and the survival rate of the hair follicle is greatly improved. However, the hair follicle can only be maintained in the needle tube when the instrument is used for air suction, and the hair follicle cannot be directly installed in the needle tube, so that the hair follicle needs to be manually loaded in the needle tube by a forceps in advance, and air pressure is also needed when the instrument is pushed out, so that the operation is complicated by switching the air pressure switch back and forth, the planting direction of the hair root is not controllable during air blowing, the planting attractiveness is influenced, and the inapplicability caused by the fact that the cutting depth and the implanting depth of the instrument cannot be adjusted is also a great defect of the instrument.
