背景技术Background technique
随着现代生活和工作压力的增大，越来越多男性面临着脱发的困扰，给患者带来沉重的心理和生理负担，目前治疗手段中最有效的是进行毛发移植，即将其它部位（简称供区）的毛发移植到脱发部位（简称受区）。With the increasing pressure of modern life and work, more and more men are facing the problem of hair loss, which brings heavy psychological and physical burdens to the patients. The most effective treatment method at present is hair transplantation, that is, hair transplantation in other parts (referred to as hair transplantation). The hair from the donor area) is transplanted to the hair loss site (referred to as the recipient area).
传统电动毛囊移植笔的结构如图1所示，包括有笔头10和管状的笔尖1，笔尖1呈标准的圆筒状，笔尖1由笔腔里面的电机驱动而高速转动。利用传统电动毛囊移植笔实施的毛发移植手术方式如下：先利用电动移植笔在供区组织41取毛，如图2所示，让高速转动的管状笔尖1钻入供区头皮组织41（如图2所示），将毛囊52与其周围的组织分离（这个过程称为“钻切”），只留有底端的微小部位仍与供区粘连，接着，用镊子夹紧毛囊并稍微用力拔起，使毛发根部底端与供区组织彻底拉断分离，将包括有完整乳头51和毛囊52的整根毛发拔出（这个过程称为“拔毛”）；然后将毛发由镊子转移装入到注射器针头（这个过程称为“装载”或“装取”），利用注射器针头在受体组织（即“受区”）钻孔（这个过程称为“打孔”），最后由注射器将毛发推入受体组织的孔中（这个过程称为“植入”）。The structure of a traditional electric hair follicle transplantation pen is shown in Figure 1, including a pen tip 10 and a tubular pen tip 1. The pen tip 1 is in a standard cylindrical shape, and the pen tip 1 is driven by a motor inside the pen cavity to rotate at high speed. The method of hair transplantation performed by using the traditional electric hair follicle transplantation pen is as follows: first, the electric transplantation pen is used to extract hair from the tissue 41 of the donor area, as shown in Figure 2, and the tubular pen tip 1 rotating at high speed is drilled into the scalp tissue 41 of the donor area (as shown in Figure 2). 2), the hair follicle 52 is separated from the surrounding tissue (this process is called "drilling"), leaving only a small part at the bottom still adhered to the donor site, and then, the hair follicle is clamped with tweezers and pulled out with a little force, The bottom of the hair root is completely separated from the tissue of the donor area, and the entire hair including the complete papilla 51 and hair follicle 52 is pulled out (this process is called "plucking"); then the hair is transferred into the syringe by tweezers The needle (a process called "loading" or "loading") is used to drill a hole in the recipient tissue (the "recipient area") with the syringe needle (a process called "punching"), and finally the syringe pushes the hair into the into the pores of the recipient tissue (a process called "implantation").
但上述毛发移植手术方式存在以下不足：However, the above-mentioned hair transplantation methods have the following disadvantages:
一、由于利用电动毛囊移植笔和镊子取毛，只能将供体的毛囊包括（毛乳头）连根拔起，供区部位的毛囊将永久缺失，毛发移植过程中，患者毛囊的总数量并没有得到增加，所以这种传统术式存在“拆东墙补西墙”的缺点，不但影响供区视觉效果，而且由于供区必须保留一定比例的毛发，因此使供区可供移植的毛发的数量受到限制；1. Due to the use of electric hair follicle transplantation pen and tweezers to extract hair, only the hair follicles (hair papilla) of the donor can be uprooted, and the hair follicles at the donor site will be permanently lost. During the hair transplantation process, the total number of hair follicles of the patient has not been obtained. increase, so this traditional technique has the disadvantage of "removing the east wall to make up the west wall", which not only affects the visual effect of the donor area, but also has a certain proportion of hair in the donor area, so the amount of hair available for transplantation in the donor area is limited. limit;
二、传统的电动毛囊移植笔只能分离毛囊组织，毛囊在供区分离后不能由电动毛囊移植笔直接转移到受区植毛，这是因为，如果电动毛囊移植笔在供区取毛后直接转移到受区钻孔并植毛，则如图3中所示，在钻孔过程中，笔尖管腔中的毛囊将受到受区原有组织的严重挤压（向上挤压，如图3中箭头所示），管腔中的毛囊及毛乳头不可能在受区立足或保持正常形态，即不可能在受区存活；所以，传统的毛囊移植笔在供区取毛后，不能直接转移到受区植毛，而需要利用镊子将毛囊从电动毛囊移植笔的管腔中转移到注射器针头（装载），但由于毛发本身很细小柔软，注射器针头开设的供毛发置入的管腔也很细小，因此装载过程费时费力，而且易损伤毛乳头及毛囊干细胞区结构，导致受区移植毛囊成活率低；2. The traditional electric hair follicle transplantation pen can only separate the hair follicle tissue. After the hair follicles are separated from the donor area, the hair follicles cannot be directly transferred to the recipient area by the electric hair follicle transplantation pen. Drill a hole in the receiving area and plant hair, then as shown in Figure 3, in the drilling process, the hair follicle in the pen tip lumen will be severely extruded by the original tissue of the receiving area (extruding upward, as indicated by the arrow in Figure 3 shown), the hair follicles and dermal papilla in the lumen cannot stand or maintain a normal shape in the recipient area, that is, it is impossible to survive in the recipient area; therefore, the traditional hair follicle transplantation pen cannot directly transfer to the recipient area after harvesting hair from the donor area Hair transplantation requires the use of tweezers to transfer the hair follicles from the lumen of the electric hair follicle transplantation pen to the syringe needle (loading), but because the hair itself is very small and soft, the lumen opened by the syringe needle for hair insertion is also very small, so loading The process is time-consuming and labor-intensive, and it is easy to damage the structure of the dermal papilla and hair follicle stem cells, resulting in a low survival rate of transplanted hair follicles in the recipient area;
三、在受区打孔只能采用手动方式，而不能采用电动方式，容易造成术者疲劳；3. Only manual methods can be used to punch holes in the receiving area, and electric methods cannot be used, which may easily cause operator fatigue;
四、操作者需多次更换手中器械（电动笔→镊子→注射器），操作步骤繁琐，费时较长。4. The operator needs to change the instrument (electric pen→tweezers→syringe) many times. The operation steps are cumbersome and time-consuming.

本发明具有以下优点和效果：The present invention has the following advantages and effects:
一、本发明的电动毛囊移植笔能够一气呵成地完成从供区取毛到受区植毛的所有操作步骤，包括在供区切开毛发周围组织、夹断毛发、提取毛发、受区打孔、受区植入毛发等所有程序步骤；而且在手术过程中毛发不需在不同器械之间转移，节省了手术时间，减低了毛发由此受损的几率，保持移植体活性，提高了移植成活率。1. The electric hair follicle transplantation pen of the present invention can complete all the operation steps from the donor area to the recipient area in one go, including cutting the tissue around the hair at the donor area, pinching the hair, extracting the hair, punching the recipient area, and In addition, the hair does not need to be transferred between different instruments during the operation, which saves operation time, reduces the chance of hair damage, maintains the activity of the graft, and improves the survival rate of the transplant.
二、本发明提取毛发和受区打孔两个步骤都可以采用电动方式，避免手动方式带来的操作慢、用力大、容易疲劳的缺点。2. In the present invention, the two steps of hair extraction and perforation of the receiving area can both be electric, so as to avoid the disadvantages of slow operation, large force and easy fatigue caused by the manual method.
三、本发明每个矩形窗口的窗底沿由外上方向内下方倾斜，因此当各刀片向下移动过程中，矩形窗口的窗底沿将会引导各刀片底沿沿倾斜方向移动，即包含有水平移位，因此能够将毛囊拦腰截断。另一方面，毛发在结构上包括头皮外侧的毛干、内侧的毛囊结构，毛囊位于皮肤表皮以下，毛囊中包括有毛乳头，毛乳头位于毛囊基底部。毛囊基底部的毛乳头具有诱导和促进毛发生长的特性，毛囊中部的隆突部有一群毛囊干细胞；进而，本发明的电动毛囊移植笔能够在毛发尚未脱离供区的前提下，直接在供区操作，将供区的毛发从毛囊下三分之一的部位拦腰截断，使毛囊下部（包括毛乳头）留在供区，而毛干及毛囊中上段的干细胞区可提走并植入受区，这样，受区植入毛发体含有毛囊中上段，可诱导受区形成新的毛乳头，新的毛乳头可诱导受区长出新的毛发；而供区则留有毛囊下段，该毛囊下段包含有毛乳头，也可诱导供区长出新的毛发。因此，供区和受区都可长出新的毛发，实现毛发倍增，而倍增的毛发又可作为新的头发移植来源，因此解决了传统技术中“拆东墙补西墙”、头发移植来源受限制的问题。3. The window bottom edge of each rectangular window of the present invention is inclined from the outside up to the inside down, so when each blade moves downward, the window bottom edge of the rectangular window will guide the bottom edge of each blade to move along the inclined direction, that is, include There is a horizontal shift, so the hair follicle can be amputated down the middle. On the other hand, the hair structure includes the hair shaft on the outside of the scalp and the hair follicle structure on the inside. The hair follicle is located under the skin epidermis. The hair follicle includes a hair papilla, and the hair papilla is located at the base of the hair follicle. The dermal papilla at the base of the hair follicle has the characteristics of inducing and promoting hair growth, and there is a group of hair follicle stem cells in the bulge in the middle of the hair follicle; furthermore, the electric hair follicle transplantation pen of the present invention can directly remove hair from the donor area before the hair is separated from the donor area. Operation, the hair in the donor area is cut off from the lower third of the hair follicle, so that the lower part of the hair follicle (including the dermal papilla) remains in the donor area, while the stem cell area of the hair shaft and the middle and upper part of the hair follicle can be removed and implanted in the recipient area , In this way, the recipient area implanted in the hair body contains the upper part of the hair follicle, which can induce the formation of new hair papilla in the recipient area, and the new hair papilla can induce the recipient area to grow new hair; while the donor area leaves the lower section of the hair follicle, and the lower section of the hair follicle Contains dermal papillae and also induces new hair growth at the donor site. Therefore, both the donor area and the recipient area can grow new hairs to achieve hair multiplication, and the multiplied hairs can be used as a new source of hair transplantation, thus solving the problem of "removing the east wall to fill the west wall" and the source of hair transplantation in the traditional technology. Restricted questions.
四、在受体组织钻孔过程中，环形滑套可以保持在下极限位置，各刀片下沿保持合拢状态，由此可以保护笔尖管腔中的毛囊不会受到受区原有组织的挤压，确保毛囊形态正常而容易存活。4. During the drilling process of the recipient tissue, the annular sliding sleeve can be kept at the lower limit position, and the lower edges of the blades are kept closed, thereby protecting the hair follicles in the nib lumen from being squeezed by the original tissue in the recipient area. Ensure that the hair follicles are morphologically normal and readily viable.

采用上述实施例的植毛手术方法步骤如下：Adopt the hair transplanting operation method step of above-mentioned embodiment as follows:
（1）.术前用皮肤激光共聚焦显微镜或超声仪测量毛囊长度及毛乳头深度，拟定手术方案，拟定供区毛发夹断点位置（使得夹断点位于毛囊中下部）；(1). Before the operation, the length of the hair follicle and the depth of the dermal papilla are measured with a skin laser confocal microscope or an ultrasound instrument, and the operation plan is drawn up, and the location of the clipping point of the hair in the donor area is drawn up (so that the clipping point is located in the middle and lower part of the hair follicle);
（2）. 启动马达9，带动笔尖1转动，按步骤（1）确定的深度在供区钻取毛囊，钻取过程中，笔头外套7的环形凸沿71暂时卡在上面一道环形凹槽61中，笔头外套7、环形滑套2的竖向位置得到定位，环形滑套2保持处于在上极限位置，各刀片3的底沿中心点位于对应矩形窗口12的窗底沿上，如图4、图7、图13所示；在笔尖1转动过程中，笔尖1会带动各刀片3、环形滑套2及轴承内圈81高速转动，而笔头6及轴承外圈82则不转动；(2). Start the motor 9 to drive the nib 1 to rotate, and drill the hair follicles in the donor area according to the depth determined in step (1). During the drilling process, the annular convex edge 71 of the nib outer casing 7 is temporarily stuck in the upper annular groove 61 Among them, the vertical positions of the nib overcoat 7 and the annular sliding sleeve 2 are positioned, the annular sliding sleeve 2 remains at the upper limit position, and the center point of the bottom edge of each blade 3 is located on the window bottom edge of the corresponding rectangular window 12, as shown in Figure 4 , shown in Fig. 7, Fig. 13; During the rotation process of nib 1, nib 1 can drive each blade 3, annular sliding sleeve 2 and bearing inner ring 81 high-speed rotations, and nib 6 and bearing outer ring 82 then do not rotate;

笔头外套74通过滚珠轴承8带动环形滑套2向下竖向移动，环形凸沿71脱离上面一道环形凹槽61，当笔头外套7的环形凸沿71到达并卡入下面一道环形凹槽62时，笔头外套7、环形滑套2的竖向位置又一次得到定位，环形滑套2向下滑动到下极限位置；在此过程中，各刀片3在矩形窗口12的倾斜窗底沿导向作用下，各刀片3的底部发生倾斜方向的移位，各刀片3的底沿中心点向中心轴线m靠拢，从而对毛发实施拦腰夹断，夹断点位于毛囊52中下部，也位于毛乳头51上方，如图14所示；The nib cover 74 drives the annular sliding sleeve 2 to move vertically downward through the ball bearing 8, and the annular convex edge 71 breaks away from the upper annular groove 61. When the annular convex edge 71 of the nib outer casing 7 reaches and snaps into the lower annular groove 62 , the vertical positions of the nib jacket 7 and the annular sliding sleeve 2 are positioned again, and the annular sliding sleeve 2 slides downward to the lower limit position; , the bottom of each blade 3 shifts in an oblique direction, and the bottom of each blade 3 moves closer to the central axis m along the central point, thereby pinching the hair down the middle. , as shown in Figure 14;
（4）. 环形凸沿71保持卡在下面一道环形凹槽62中，环形滑套2保持在下极限位置，将笔尖1从供区组织41拔出，供区头发的上段52（毛囊中上段，下称“移植体52”）位于笔尖1空腔中而离开供区41，供区头发的毛囊下段（含有毛乳头51）则仍留在供区41，如图15所示；(4). The ring-shaped convex edge 71 is kept stuck in the lower ring-shaped groove 62, the ring-shaped sliding sleeve 2 is kept at the lower limit position, and the nib 1 is pulled out from the tissue 41 of the donor area. Hereinafter referred to as "transplant 52") is located in the cavity of the nib 1 and leaves the donor area 41, while the lower hair follicle (including the dermal papilla 51) of the donor area remains in the donor area 41, as shown in Figure 15;
（5）.电动毛囊移植笔的笔尖带着移植体52转移到受区42，在受区42拟植入毛发位置打孔，打孔过程中马达9启动，笔尖（包括笔尖1、刀片3）高速转动，移植体52跟随笔尖1转动，转动过程中，笔头外套7的环形凸沿71保持卡在下面一道环形凹槽62，环形滑套2保持在下极限位置，各刀片3的底沿中心点保持靠拢，从而保护移植体52不受受区42组织的挤压，使移植体52保持正常形态，如图16所示；(5). The nib of the electric hair follicle transplantation pen is transferred to the receiving area 42 with the transplant body 52, and a hole is made in the receiving area 42 where the hair is to be implanted. Rotate at a high speed, and the transplant body 52 follows the nib 1 to rotate. During the rotation, the annular convex edge 71 of the nib outer cover 7 remains stuck in the lower annular groove 62, and the annular sliding sleeve 2 remains at the lower limit position. keep close together, so as to protect the graft body 52 from being extruded by the tissue of the recipient area 42, so that the graft body 52 maintains a normal shape, as shown in FIG. 16 ;
（6）. 受区打孔完成后，关闭马达9，笔尖1停止转动，用手捏住笔头外套7并且用力向上推动笔头外套7竖向移动，笔头外套7通过滚珠轴承8带动环形滑套2向上竖向移动，环形凸沿71脱离下面一道环形凹槽62，当笔头外套7的环形凸沿71卡入上面一道环形凹槽61时，笔头外套7、环形滑套2的竖向位置又一次得到定位，使环形滑套2向上滑动到上极限位置，各刀片3在矩形窗口12的窗底沿导向作用下，向外回缩，各刀片3的底沿中心点重新回到对应矩形窗口12的窗底沿上，各爪状的刀片3将移植体52松开，如图17所示；(6). After the receiving area is punched, turn off the motor 9, the nib 1 stops rotating, pinch the nib jacket 7 with your hands and push the nib jacket 7 upwards to move vertically, and the nib jacket 7 drives the annular sliding sleeve 2 through the ball bearing 8 Move vertically upwards, and the annular convex edge 71 breaks away from the lower annular groove 62. When the annular convex edge 71 of the nib outer cover 7 snaps into the upper annular groove 61, the vertical position of the nib outer jacket 7 and the annular sliding sleeve 2 will be changed again. After being positioned, the annular sliding sleeve 2 slides upward to the upper limit position, and each blade 3 retracts outward under the guidance of the window bottom edge of the rectangular window 12, and the bottom edge center point of each blade 3 returns to the corresponding rectangular window 12 again. On the bottom edge of the window, each claw-shaped blade 3 loosens the implant 52, as shown in Figure 17;
（7）. 再次启动马达9，带动笔尖1转动，从受区42缓慢拔起笔尖1，拔起过程保持笔尖高速转动，笔尖高速转动会使笔尖1与移植体52不会黏在一起，另一方面移植体52下端会与受区组织会黏在一起，并在移植体52自重作用下，移植体52留在受区组织中，如图18所示；(7). Start the motor 9 again to drive the nib 1 to rotate, slowly pull out the nib 1 from the receiving area 42, and keep the nib rotating at a high speed during the pulling process. The high-speed rotation of the nib will make the nib 1 and the implant 52 not stick together. On the one hand, the lower end of the graft body 52 will stick to the tissue of the recipient area, and under the weight of the graft body 52, the graft body 52 will remain in the tissue of the recipient area, as shown in FIG. 18 ;
这样，受区植入的移植体52含有毛囊中上段，含有毛囊干细胞，可诱导形成新的毛乳头，新的毛乳头可诱导受区长出新的毛发；而供区则留有毛囊下段，该毛囊下段包含有毛乳头，也可诱导供区长出新的毛发。因此，供区和受区都可长出新的毛发，实现毛发倍增，而倍增的毛发又可作为新的头发移植来源，因此解决了头发移植来源受限制的问题。In this way, the graft 52 implanted in the receiving area contains the middle and upper sections of hair follicles, containing hair follicle stem cells, which can induce the formation of new dermal papillae, which can induce new hair growth in the receiving area; while the donor area has the lower section of hair follicles, The lower segment of the follicle contains the dermal papilla, which also induces new hair growth in the donor area. Therefore, both the donor area and the recipient area can grow new hairs to realize hair multiplication, and the multiplied hairs can be used as new sources of hair transplantation, thus solving the problem of limited sources of hair transplantation.
由于本发明的笔尖能够从四周方向将毛囊拦腰切断，故称为“环切式”。Because the pen tip of the present invention can cut off the hair follicles from the surrounding direction, it is called "circumcision type".
