本发明涉及医用设备技术领域，特别是涉及一种头皮止血夹、头皮缝夹装置，以及应用该装置实现开颅时切开头皮后的缝夹止血方法和关颅时的免缝对合头皮的方法。The invention relates to the technical field of medical equipment, in particular to a scalp hemostatic clip, a scalp suture clip device, and a method of applying the device to achieve hemostasis with a suture clip after incising the scalp during craniotomy, and a suture-free butt joint scalp device during craniotomy. method.
背景技术Background technique
开颅手术中，开颅时需要进行切开头皮，关颅时需缝合头皮。头皮部的皮肤具有以下特点：1、血运丰富，血管主要位于帽状腱膜外侧；2、帽状腱膜是坚韧的致密腱膜；3、帽状腱膜下层是疏松的结蹄组织，极易实现钝性分离；4、头皮下方是坚硬的颅骨；5头皮表层的头发快速生长。因头皮不同于其他部位的皮肤，开颅时切开头皮过程与关颅的缝合头皮过程也不同于其他部位的手术。在临床应用数十年的皮肤缝合器，以及近几年的皮肤粘连免缝(头皮的头发生长，难以粘连牢固)，在头皮缝合过程中难以应用。In craniotomy, the scalp needs to be incised during craniotomy, and the scalp needs to be sutured during craniotomy. The skin of the scalp has the following characteristics: 1. The blood supply is rich, and the blood vessels are mainly located outside the galeal aponeurosis; 2. The galeal aponeurosis is a tough and dense aponeurosis; 3. The subgaleal aponeurosis is a loose hoof tissue, It is very easy to achieve blunt separation; 4. The underside of the scalp is a hard skull; 5. The hair on the surface of the scalp grows rapidly. Because the scalp is different from other parts of the skin, the process of scalp incision during craniotomy and the process of suturing the scalp during craniotomy are also different from other parts of the operation. The skin stapler, which has been used clinically for decades, and the suture-free skin adhesion in recent years (hair growth on the scalp is difficult to adhere firmly), are difficult to apply in the process of scalp suture.
现有技术中，在开颅的切开头皮过程中，需要采取头皮夹来减少伤口出血。切开头皮后，利用帽状腱膜下层极易钝性分离的特性，将“C”型头皮夹一端插入帽状腱膜下层，另一端卡在皮肤表面，头皮夹的中间部分包裹切口边缘，“C”型头皮夹变形后的收缩力压迫夹在中间的头皮血管，减少头皮出血，临时解决术中头皮出血的问题；关颅的缝合头皮过程，需首先拆除“C”型头皮夹，接着缝合帽状腱膜，最后缝合头皮表层。“C”型头皮夹夹住切口边缘后能减少头皮出血，但这种方法存在以下不足：In the prior art, in the process of incising the scalp of the craniotomy, a scalp clip needs to be used to reduce wound bleeding. After the scalp is incised, the "C"-type scalp clip is inserted into the subgaleal layer at one end, and the other end is stuck on the skin surface, using the characteristics of the subgaleal layer that is easily bluntly separated. The middle part of the scalp clip wraps the edge of the incision. The contraction force of the deformed "C" type scalp clip compresses the scalp blood vessels in the middle, reduces scalp bleeding, and temporarily solves the problem of intraoperative scalp bleeding; in the process of sutured scalp, the "C" type scalp clip needs to be removed first, and then The galeal aponeurosis is sutured, and finally the scalp surface is sutured. "C" type scalp clips can reduce scalp bleeding after clamping the incision edge, but this method has the following disadvantages:
1、“C”型头皮夹包裹切口边缘，阻挡头皮切口边缘的动脉血管等结构的显露，难以进行准确电凝动脉血管等手术操作；2、松开“C”型头皮夹后头皮的再出血，导致术野不清，对后续的缝合帽状腱膜及头皮造成困难；3、头皮缝合后“C”型头皮夹被拆除，只剩下横向的缝线压迫头皮止血，效果有限，部分患者术后会出现头皮迟发性动脉出血，而此时因头皮表层已经被缝合，出血流向里面，需再次手术； 4、操作费时、出血多，使用“C”型头皮夹的过程包括切开头皮、电凝止血、逐一上头皮夹，逐一松开头皮夹、再次电凝止血等操作，过程繁琐。1. "C" type scalp clip wraps the edge of the incision, blocking the exposure of structures such as arteries and blood vessels at the edge of the scalp incision, making it difficult to perform surgical operations such as accurate coagulation of arterial blood vessels; 2. Re-bleeding of the scalp after loosening the "C" type scalp clip , resulting in unclear surgical field and difficulty in subsequent suturing of the galeal aponeurosis and the scalp; 3. After the scalp is sutured, the "C" type scalp clip is removed, leaving only the transverse suture to compress the scalp to stop bleeding, with limited effect, and some patients There will be delayed arterial bleeding of the scalp after the operation. At this time, because the surface of the scalp has been sutured, the bleeding will flow to the inside, and the operation needs to be repeated. 4. The operation is time-consuming and bleeding. The process of using the "C" type scalp clip includes cutting the scalp. , electrocoagulation to stop bleeding, put on the scalp clips one by one, loosen the scalp clips one by one, and re-coagulation to stop bleeding, etc., the process is cumbersome.
此外，传统的针线缝合头皮存在以下不足：In addition, the traditional needle and thread to suture the scalp has the following shortcomings:
1、因头皮血运丰富，缝线紧绷(因为需用缝线压迫止血)，术后头皮会发生一定程度的肿胀，导致缝线对局部皮肤产生卡压，致使局部皮肤缺血、甚至坏死，影响伤口愈合；2、缝线作用面窄，对局部皮肤的压力大，头皮在肿胀阶段紧绷的缝线会对皮肤产生切割作用，形成横向疤痕，此疤痕与纵向切口疤痕交叉，形成“蜈蚣疤”，影响美观。3、针线缝合对医生水平的依赖程度较高，缝合消耗的时间较长。1. Because the scalp is rich in blood supply and the sutures are tight (because the sutures need to be compressed to stop bleeding), the scalp will swell to a certain extent after surgery, which will cause the sutures to compress the local skin, resulting in local skin ischemia and even necrosis. , affecting wound healing; 2. The suture surface is narrow, and the pressure on the local skin is large. The tight suture of the scalp in the swelling stage will cut the skin and form a horizontal scar, which intersects with the longitudinal incision scar, forming a " Centipede Scar", which affects aesthetics. 3. Needle and thread suture is highly dependent on the doctor's level, and the suture consumes a long time.

(三)有益效果(3) Beneficial effects
本发明提供的头皮止血夹，通过缝线将扣压板固定在头皮上，通过缝线盒的自身结构使得固定在头皮中的缝线的长度可调节，当头皮发生肿胀时，通过抽出缝线盒中缠绕的缝线，增加进入头皮中的缝线的长度，降低缝线张力，改善伤口血运；当需要缩短缝线长度时，通过提拉扣压板第二贯通孔中的缝线，使得进入头皮中的缝线缩短，升高缝线张力，减轻头皮出血。本发明中的头皮止血夹，安装方便，能实现头皮的快速止血，且在扣压板固定在头皮上以后，能通过调节缝线的长度来调节扣压板对头皮的压紧程度，在不对头皮切口造成二次创伤的同时，保证了最佳止血效果。本发明提供的头皮缝夹装置，通过在装置的壳体两侧设置送线单元，能为头皮缝夹过程中不断提供针线和扣压板，保证缝夹过程的顺利进行；通过将针线子单元中的缝针设置为弧形，使得提供缝线的缝线盒、扣压板与缝针之间位置更紧凑高效，同时方便了整个缝线子单元与装置的脱离，此外，由于缝针为弧形，缩小了缝线过程中缝针的运动范围，使得装置整体更加紧凑；装置设置为对称结构，在进行缝夹的过程中，头皮切口两侧的扣压板同步安装，不会发生错位现象，方便后续的头皮对合。本发明提供的头皮缝夹装置，通过缝线将扣压板固定在头皮上，由于缝线受力面积小，局部压力大，对位于缝线和压板之间的头皮进行压迫，进而压迫头皮血管，减少出血，起到压迫止血的作用，同时头皮表面的扣压板受力面积较大，局部压力较小，对头皮表面影响小；该装置不仅能在术中切开头皮的同时实现头皮快速缝夹止血，还能一直显露切口缘，便于实现头皮中较粗动脉的电凝止血；该装置使用过程简单方便，简化了头皮夹压止血的程序，通过将分别位于伤口两侧的扣压板相对合后进行固定，能实现伤口的免缝对合，避免了术后缝线压迫导致的横向疤痕，不会形成“蜈蚣疤”，有助于术后康复，且最大限度减小了疤痕面积；由于实际手术中，未进行头皮切口的缝合，遇到少数头皮血管迟发性动脉出血时，出血不会流向深面(会流向头皮外)，可避免迟发性皮下血肿，同时出血流向头皮外，易于观察与及时处理；通过使用本发明中的对合头皮的装置及免缝对合头皮的方法，可大大缩短手术时间，减少出血，减轻疤痕。The scalp hemostatic clip provided by the present invention fixes the pressing plate on the scalp through sutures, and the length of the sutures fixed in the scalp can be adjusted through the self-structure of the suture box. When the scalp is swollen, the suture box is pulled out The suture wound in the middle increases the length of the suture entering the scalp, reduces the tension of the suture, and improves the blood supply of the wound; when the length of the suture needs to be shortened, the suture in the second through hole of the buckle plate is pulled to make the suture enter the scalp. The sutures in the scalp are shortened, increasing suture tension and reducing scalp bleeding. The scalp hemostatic clip in the present invention is easy to install, can achieve rapid hemostasis of the scalp, and after the clipping plate is fixed on the scalp, the compression degree of the clipping plate on the scalp can be adjusted by adjusting the length of the suture. While causing secondary trauma, it ensures the best hemostatic effect. In the scalp seam clip device provided by the present invention, by arranging the thread feeding units on both sides of the casing of the device, the needle thread and the pressing plate can be continuously provided for the scalp seam clipping process, so as to ensure the smooth progress of the seam clipping process; The suture needle is set in an arc shape, which makes the position between the suture box, the buckle plate and the suture needle that provide the suture more compact and efficient, and at the same time facilitates the separation of the entire suture sub-unit from the device. In addition, because the suture needle is in an arc shape , which reduces the movement range of the sewing needle during the suture process, making the device more compact as a whole; the device is set to a symmetrical structure. During the process of sewing clips, the withholding plates on both sides of the scalp incision are installed synchronously, and there will be no dislocation phenomenon, which is convenient for follow-up. scalp involution. The scalp suture clip device provided by the present invention fixes the pressing plate on the scalp through the suture. Due to the small force area of the suture and the large local pressure, the scalp between the suture and the pressing plate is compressed, thereby compressing the blood vessels of the scalp. Reduce bleeding, play the role of compression and hemostasis, and at the same time, the withholding plate on the scalp surface has a larger force area, less local pressure, and less impact on the scalp surface; the device can not only incise the scalp during surgery, but also realize rapid scalp clipping Hemostasis, and the incision edge can be exposed all the time, which is convenient to achieve hemostasis by electrocoagulation of thicker arteries in the scalp; the device is simple and convenient to use, and simplifies the procedure of scalp crimping hemostasis. Fixation can achieve suture-free closure of the wound, avoid transverse scars caused by postoperative suture compression, and will not form "centipede scars", which is helpful for postoperative recovery and minimizes the scar area; During the operation, the scalp incision was not sutured, and when there was delayed arterial hemorrhage from a few scalp blood vessels, the bleeding would not flow to the deep side (it would flow to the outside of the scalp), which could avoid delayed subcutaneous hematoma. At the same time, the bleeding flowed to the outside of the scalp. Observation and timely treatment; by using the device for abutting the scalp and the method for abutting the scalp without sutures in the present invention, the operation time can be greatly shortened, the bleeding and the scarring can be reduced.

本发明实施例中提供的头皮止血夹，包括扣压板、缝线，缝线的一端用于穿过头皮后再穿过设置在扣压板一端的第一贯通孔，缝线的另一端用于穿过头皮后再穿过设置在扣压板另一端的第二贯通孔，以使缝线与位于头皮表面的扣压板形成压夹头皮的状态。The scalp hemostatic clip provided in the embodiment of the present invention includes a pressing plate and a suture. One end of the suture is used to pass through the scalp and then pass through the first through hole provided at one end of the pressing plate, and the other end of the suture is used to pass through the scalp. After passing through the scalp, pass through the second through hole provided at the other end of the clipping plate, so that the suture and the clipping plate on the scalp surface form a state of clipping the scalp.
具体地，如图16中所示，为方便观察，将扣压板进行了部分剖切。本实施例中的头皮止血夹，使用时位于头皮切口两侧且位于头皮上表面的扣压板为长条形结构，缝线用于将扣压板固定在头皮表面上。使用时，需要使缝线的中间部位位于头皮的下方，缝线的一端用于穿过头皮后，从扣压板上的第一贯通孔穿过，此时缝线位置是暂时固定的。缝线的另一端用于穿过头皮后，从扣压板上的第二贯通孔穿出并固定，以使缝线与位于头皮表面的扣压板形成压夹头皮的状态。从第二贯通孔穿出的缝线会通过其他部件或扣压板自身结构实现单向固定，使其只能从扣压板下方向上抽出，反向则不能抽回。例如在扣压板第二贯通孔内设置能防止缝线倒抽回的单向线卡，此时的缝线对位于头皮表面的扣压板施加了向下的拖拽力，头皮被夹在缝线和扣压板之间，由于此时缝线两端固定，缝线和扣压板对头皮形成压夹状态，头皮切口边缘被压紧，进而实现止血效果。Specifically, as shown in FIG. 16 , for the convenience of observation, the withholding plate is partially cut. In the scalp hemostatic clip in this embodiment, the buckling plates located on both sides of the scalp incision and on the upper surface of the scalp are in a long strip structure, and the sutures are used to fix the buckling plates on the scalp surface. When in use, the middle part of the suture needs to be located below the scalp, and one end of the suture is used to pass through the first through hole on the buckle plate after passing through the scalp. At this time, the position of the suture is temporarily fixed. After the other end of the suture is used to pass through the scalp, it is passed through the second through hole on the clipping plate and fixed, so that the suture and the clipping plate on the scalp surface form a state of clipping the scalp. The suture passing through the second through hole will be fixed in one direction by other components or the structure of the buckle plate itself, so that it can only be pulled upward from the bottom of the buckle plate, and cannot be withdrawn in the reverse direction. For example, a one-way thread clip that can prevent the suture from being pulled back is provided in the second through hole of the buckle plate. At this time, the suture exerts a downward drag force on the buckle plate located on the surface of the scalp, and the scalp is clamped by the suture. Since the two ends of the suture are fixed at this time, the suture and the pressing plate form a pressure-clamping state on the scalp, and the edge of the scalp incision is compressed, thereby achieving the effect of hemostasis.
本发明提供的头皮止血夹，通过缝线将扣压板固定在头皮上，当头皮发生肿胀时，通过调整深入头皮的缝线的长度，降低缝线张力，改善伤口血运；当需要缩短缝线长度时，通过提拉扣压板第二贯通孔中的缝线，使得进入头皮中的缝线缩短，升高缝线张力，减轻头皮出血。本发明中的头皮止血夹，安装方便，能实现头皮的快速止血，且在扣压板固定在头皮上以后，能通过调节缝线的长度来调节扣压板对头皮的压紧程度，在不对头皮切口造成二次创伤的同时，保证了最佳止血效果。The scalp hemostatic clip provided by the invention fixes the pressing plate on the scalp through sutures. When the scalp is swollen, the length of the sutures deep into the scalp is adjusted to reduce the tension of the sutures and improve the blood supply of the wound; when the sutures need to be shortened When the length of the suture is raised, the suture in the second through hole of the buckle plate is pulled to shorten the suture entering the scalp, increase the tension of the suture, and reduce the bleeding of the scalp. The scalp hemostatic clip in the present invention is easy to install, can achieve rapid hemostasis of the scalp, and after the clipping plate is fixed on the scalp, the compression degree of the clipping plate on the scalp can be adjusted by adjusting the length of the suture. While causing secondary trauma, it ensures the best hemostatic effect.
优选地，第一贯通孔上方还设有缝线盒，缝线置于缝线盒内，缝线盒通过释放缝线以延长穿入头皮的缝线的长度，缝线盒释放缝线的过程中，需要一定的牵拉力，缝线才能从缝线盒中释放出来。第二贯通孔内设有实现缝线单向运动的阻尼件，例如该阻尼件为设置在第二贯通孔内的倒刺，或设置在第二贯通孔中的单向线卡，以实现对缝线的单向固定。倒刺易于加工，固定缝线的效果良好，且不需要耗费额外的材料。Preferably, a suture box is also provided above the first through hole, the suture is placed in the suture box, and the suture box releases the suture to extend the length of the suture penetrating the scalp. The process of releasing the suture from the suture box , some pulling force is required to release the suture from the suture box. The second through hole is provided with a damping member for realizing unidirectional movement of the suture. Unidirectional fixation of sutures. The barbs are easy to process and provide good suture retention without the need for additional material.
需要说明的是，缝线盒在使用前，可以不处于第一贯通孔上方，可以以如图4中所示的方式进行设置，使用过程中，由于缝线的拖拽力，使得缝线盒逐渐向第一贯通孔的位置处移动，最终卡在第一贯通孔口上，同时起到固定缝线的作用。It should be noted that the suture box may not be located above the first through hole before use, and can be set as shown in FIG. It gradually moves to the position of the first through hole, and finally gets stuck on the first through hole, and at the same time plays the role of fixing the suture.
头皮的切口愈合过程中，头皮会发生一定程度的肿胀是正常现象，此时需要调节扣压板和缝线压夹头皮的力度，实现一定程度的松解，以适应头皮的正常变化。优选地，通过将缝线盒设置为依次粘连的多层子缝线盒来实现对缝线长度的调节，缝线绕置于子缝线盒内。如图4、图6、图16中所示，缝线通过特殊的绕线方式绕置于多个子缝线盒内，缝线盒包括第一子缝线盒3021，第二子缝线盒3022，第三子缝线盒3023，缝线盒302上设置固线孔3026，缝线304通过固线孔3026 绕置于上述的子缝线盒内。各个子缝线盒的材质可以采用石蜡或易于破坏的材质，使用时可逐一拆解下，对缝线304既能起到固定作用，还能提供较小的限制力，使得必要时缝线304能完全从多个子缝线盒中脱出，以实现缝线304长度的调整。当然位于最后的子缝线盒需要起到将缝线固定在扣压板外以防止缝线从第一贯通孔完全穿过的作用。通过将缝线盒制成多层结构，能方便地控制所需缝线的长度，进而实现扣压板的快速松解，以调节压紧头皮的压紧力，防止因头皮肿胀产生太大的压紧力而对头皮造成伤害。当需要增加扣压板的压紧力时，只需要向外抽取第二贯通孔中的缝线即可。During the healing process of the scalp incision, it is normal for the scalp to swell to a certain extent. At this time, it is necessary to adjust the strength of the withholding plate and the suture to clamp the scalp to achieve a certain degree of loosening, so as to adapt to the normal changes of the scalp. Preferably, the adjustment of the length of the suture is realized by arranging the suture box as a multi-layer sub-suture box which is adhered in sequence, and the suture is wound in the sub-suture box. As shown in Figure 4, Figure 6, Figure 16, the suture is wound into a plurality of sub-suture boxes by a special winding method. The suture box includes a first sub-suture box 3021 and a second sub-suture box 3022. , the third sub-suture box 3023, the suture box 302 is provided with a fixing hole 3026, and the suture 304 is wound into the above-mentioned sub-suture box through the fixing hole 3026. The material of each sub-suture box can be made of paraffin or easily damaged material, and can be disassembled one by one during use, which can not only play a role in fixing the suture 304, but also provide a small restraining force, so that the suture 304 can be used when necessary. Fully removable from multiple sub-suture boxes to enable adjustment of the length of the suture 304. Of course, the last sub-suture box needs to play the role of fixing the suture outside the buckle plate to prevent the suture from completely passing through the first through hole. By making the suture box into a multi-layer structure, the length of the required suture can be easily controlled, thereby realizing the rapid release of the buckle plate, so as to adjust the pressing force of pressing the scalp and prevent too much pressure due to scalp swelling. Tight and cause damage to the scalp. When the pressing force of the withholding plate needs to be increased, it is only necessary to extract the suture in the second through hole outward.

具体地，本发明实施例提供的头皮缝夹装置的工作过程如图12- 图15中所示。初始位置如图12中所示，此时一个针线子单元30被推入至壳体1内，扣压板303与壳体下部101之间的空间为容置头皮的头皮放置区8，此时扣压板303下方脱离支撑底板331的束缚，缝线盒302 的一侧也由于支撑杆的长短不一而脱离第二支撑杆35的束缚。此时的缝针301的内侧面正好位于第一驱动轮轴203的上方。为了能使缝针 301不脱离设定的运动轨迹，缝针301的两侧均应该有限位装置，位于内侧面的第一驱动轮轴203能起到限位作用，当然可以在缝针301两侧均设置第一驱动轮轴203，同时起到驱动和限位的作用。优选地，驱动轮轴位于缝针301的一侧，缝针301的另一侧设置限位件，缝针301 在驱动轮轴和限位件的引导下沿圆形轨迹运动。进一步地，限位件为能绕自身轴线转动的圆轴。缝针301的外侧面位于第一限位件40的下方，这样缝针301的运动轨迹即被限定在一个圆周轨道内。驱动实现第一驱动轮轴203的旋转，第一驱动轮轴203与缝针301内侧面的接触面均为粗糙面，通过相互间的摩擦力带动缝针301实现旋转运动。如图13为缝针301转过近90度时的示意图，转动过程中，随着缝针301 针头距离原始位置越来越远，松弛的缝线304开始紧绷，进一步开始从缝线盒302中抽出，当缝针301末端脱离缝线盒302的卡槽3025时，缝线盒302由于缝线304的拖拽开始向图13中的右侧倾斜，并被拖拽至扣压板303左侧，如图14所示中所示。优选地，扣压板303的上表面设置如图4中所示的台阶面3033，缝线盒302倾倒后被拖拽至扣压板303 左侧，并卡接在台阶面3033中，实现缝线盒302位置的固定，保证缝线304的正常输送。此时的缝针301主要通过第二驱动轮轴204进行驱动，驱动力同样来自摩擦力。运动过程中，位于第一驱动轮轴203旁边的凸轮5在摩擦力的驱动下，例如第一驱动轮轴203逆时针旋转，则凸轮5顺时针旋转，凸轮5的小端持续对扣压板303施加向下的压力，以保证扣压板303不翘起，方便缝针301的顺利穿出。当缝针301带动缝线304运动至如图14所示的位置时，由于缝线盒302内的缝线304的长度是固定的，缝线304的反向拖拽力大于摩擦力的时候，缝针301 停止运动。将装置整体向左推动，推动方向沿伤口的前方，由于此时的扣压板303已经通过缝线304和缝针301固定在了头皮上，因此针线子单元30会很快整体从壳体1侧方的开口1000脱出，形成如图15所示的位置关系，至此一个针线子单元30被固定在了头皮上，由于装置为对称结构，因此伤口两侧的头皮能实现扣压板303的同步压夹，下一组针线子单元30被弹簧推至壳体1处，进入下一次的压夹准备状态。如此多次操作，根据需要即可将头皮两侧的伤口处均匀固定设定数量的扣压板303，最后统一将缝针301拔出，扣压板303由于其自身结构设计，能将从第二贯通孔3034抽出的缝线304限制为单向运动，只能从下向上穿出，不能从上向下退回，以实现缝线304的固定，进一步实现所有扣压板303的压夹功能。优选地，第二贯通孔3034内设有固定缝线304的倒刺3032，如图5中所示，通过倒刺3032能限制缝线304 的反向缩回，简单易实现。Specifically, the working process of the scalp sewing clip device provided by the embodiment of the present invention is shown in FIGS. 12-15 . The initial position is shown in FIG. 12 . At this time, a needle thread sub-unit 30 is pushed into the housing 1, and the space between the pressing plate 303 and the lower part 101 of the housing is the scalp placing area 8 for accommodating the scalp. The bottom of the plate 303 is freed from the restraint of the support bottom plate 331 , and one side of the suture box 302 is also freed from the restraint of the second support rod 35 due to the different lengths of the support rods. At this time, the inner side of the sewing needle 301 is just above the first driving wheel shaft 203 . In order to keep the sewing needle 301 from deviating from the set movement track, both sides of the sewing needle 301 should have limiting devices. Both are provided with a first driving wheel shaft 203, which plays the role of driving and limiting at the same time. Preferably, the driving axle is located on one side of the sewing needle 301, the other side of the sewing needle 301 is provided with a stopper, and the sewing needle 301 moves along a circular trajectory under the guidance of the driving axle and the stopper. Further, the limiting member is a circular shaft that can rotate around its own axis. The outer surface of the sewing needle 301 is located below the first limiting member 40 , so that the movement track of the sewing needle 301 is limited within a circular track. The first driving wheel shaft 203 is driven to rotate, and the contact surfaces between the first driving wheel shaft 203 and the inner side of the sewing needle 301 are rough surfaces, and the sewing needle 301 is driven to rotate by mutual frictional force. Fig. 13 is a schematic diagram when the sewing needle 301 is rotated nearly 90 degrees. During the rotation, as the needle head of the sewing needle 301 is farther and farther away from the original position, the loose suture 304 begins to tighten, and further begins to flow from the suture box 302 13, when the end of the needle 301 is released from the slot 3025 of the suture box 302, the suture box 302 begins to incline to the right in FIG. , as shown in Figure 14. Preferably, a stepped surface 3033 as shown in FIG. 4 is provided on the upper surface of the buckling plate 303, and the suture box 302 is dragged to the left side of the buckling plate 303 after being overturned, and clamped in the stepped surface 3033 to realize the suture box The fixation of the position of 302 ensures the normal delivery of the suture 304 . At this time, the sewing needle 301 is mainly driven by the second driving wheel shaft 204, and the driving force also comes from the friction force. During the movement, the cam 5 located next to the first driving wheel shaft 203 is driven by friction, for example, the first driving wheel shaft 203 rotates counterclockwise, the cam 5 rotates clockwise, and the small end of the cam 5 continues to exert pressure on the buckling plate 303. to ensure that the pressing plate 303 does not lift up, so as to facilitate the smooth passing of the sewing needle 301 . When the needle 301 drives the suture 304 to move to the position shown in FIG. 14 , since the length of the suture 304 in the suture box 302 is fixed, when the reverse drag force of the suture 304 is greater than the frictional force, Needle 301 stops moving. Push the device as a whole to the left, and the pushing direction is along the front of the wound. Since the pressing plate 303 has been fixed on the scalp by the suture 304 and the suture needle 301 at this time, the needle thread sub-unit 30 will soon be completely removed from the casing 1 side. The square opening 1000 comes out to form the positional relationship as shown in Figure 15. So far, a needle thread sub-unit 30 is fixed on the scalp. Since the device is of a symmetrical structure, the scalp on both sides of the wound can be synchronously clamped by the withholding plate 303. , the next group of needle thread sub-units 30 is pushed to the housing 1 by the spring, and enters the next press-clamping ready state. After so many operations, the wounds on both sides of the scalp can be evenly fixed with a set number of pressing plates 303 as needed, and finally the sewing needles 301 are pulled out uniformly. Due to its own structural design, the pressing plates 303 can pass through the second The suture 304 drawn out of the hole 3034 is limited to one-way movement, and can only be passed out from the bottom to the top, and cannot be retracted from the top to the bottom, so as to realize the fixation of the suture 304 and further realize the clamping function of all the clamping plates 303 . Preferably, the second through hole 3034 is provided with barbs 3032 for fixing the suture 304. As shown in FIG. 5, the reverse retraction of the suture 304 can be restricted by the barbs 3032, which is simple and easy to implement.
在缝针301运动至如图13或图14所示的位置时，由于第二驱动轮轴204上的特殊结构设计，能使缝线304不完全跟随缝针301的运动轨迹，而在与第二驱动轮轴204接触的过程中即被第二驱动轮轴 204上的凸筋207结构改变运动轨迹，脱离第二驱动轮轴204的限制，从其侧方脱出，即图14中垂直纸面的方向，然后移至第二驱动轮轴 204的上方，但仍然位于头皮下方，这样缝线304能紧贴头皮下方延伸，而不会挂在第二驱动轮轴204上不脱离。When the sewing needle 301 moves to the position shown in FIG. 13 or FIG. 14 , due to the special structural design on the second driving wheel shaft 204 , the sewing thread 304 can not completely follow the movement track of the sewing needle 301 , and the During the contacting process of the driving wheel shaft 204, the movement trajectory is changed by the structure of the convex rib 207 on the second driving wheel shaft 204, and it escapes from the restriction of the second driving wheel shaft 204 and escapes from its side, that is, the direction perpendicular to the paper in FIG. 14, and then Move over the second drive axle 204, but still under the scalp, so that the suture 304 can run snugly under the scalp and not hang on the second drive axle 204 and become detached.
