一种一次性内窥镜螺旋形连续缝合针Disposable endoscope spiral continuous suture needle

技术领域technical field

本发明涉及内窥镜手术工具技术领域，尤其是一种一次性内窥镜螺旋形连续缝合针。The invention relates to the technical field of endoscopic surgical tools, in particular to a disposable endoscopic spiral continuous suture needle.

背景技术Background technique

内窥镜术(endoscopy)，应用可送入人体腔、道内的窥镜在直观下进行检查及治疗的技术。检查与外界相通的腔道（如消化道、呼吸道、泌尿道等），可直接将内窥镜插入，这称为无创伤性内窥镜检查术；检查密闭的体腔（如胸腔、腹腔、关节腔等），需通过切口将内窥镜送入，这称为创伤性内窥镜术。在内窥镜检查的同时，若使用各种配件，尚可进行治疗。Endoscopy is a technology that uses endoscopes that can be sent into human cavities and tracts to perform inspection and treatment under direct inspection. Check the cavities that communicate with the outside world (such as digestive tract, respiratory tract, urinary tract, etc.), and the endoscope can be inserted directly, which is called non-invasive endoscopy; check closed body cavities (such as chest cavity, abdominal cavity, joints, etc.) cavity, etc.), the endoscope needs to be introduced through an incision, which is called traumatic endoscopy. At the same time as endoscopy, treatment can still be performed if various accessories are used.

随着医疗水平的发展，内窥镜手术日益的增多，其中针对肠胃手术的术口也由黏膜层切除发展至5层切除，术口的大小也有小于1厘米发展到3厘米左右。而这种术口缝合，在内窥镜手术下，目前的钛夹封合术不利于全层连续缝合，当术口大于2厘米，缝合的难度非常大，甚至要借助尼龙绳、尼龙圈等辅助缝合。如果内镜下中无法缝合，就要改为外科开腹手术加缝合术，这样会加重了患者的手术经济负担及手术风险。With the development of medical level, the number of endoscopic surgery is increasing day by day. Among them, the surgical opening for gastrointestinal surgery has also developed from mucosal layer resection to 5-layer resection, and the size of the surgical opening has also developed from less than 1 cm to about 3 cm. For this kind of suture, under endoscopic surgery, the current titanium clip sealing is not conducive to full-thickness continuous suture. When the incision is larger than 2 cm, the suture is very difficult, and even nylon ropes, nylon loops, etc. are needed. Auxiliary suture. If the suture cannot be sutured under the endoscope, surgical laparotomy plus suture should be used, which will increase the economic burden and surgical risk of the patient.

如图1至图4所示，本实施例提供的一种一次性内窥镜螺旋形连续缝合针，包括基体1、金属缝合线2和缝合针3，所述金属缝合线2整体呈螺旋状，所述金属缝合线2包括收拢部21和缝合部22，所述收拢部21的直径保持一致，所述缝合部22的端口呈喇叭状向外延展，所述收拢部21一端与缝合部22连接为一体，使所述收拢部21与缝合部22保持连贯，所述收拢部21的另一端与基体1固定连接，所述基体1设置有可供活检钳夹持的夹持部11，所述缝合部22的端头处可拆卸式安装有缝合针3。As shown in FIGS. 1 to 4 , a disposable endoscope spiral continuous suture needle provided in this embodiment includes a base body 1 , ametal suture thread 2 and asuture needle 3 , and themetal suture thread 2 is in a spiral shape as a whole. , themetal suture 2 includes acondensed part 21 and asewn part 22, the diameter of thecondensed part 21 is kept the same, the port of thesewn part 22 extends outward in a trumpet shape, and one end of thecondensed part 21 is connected with thesewn part 22 The connection is integral, so that thecollection part 21 and thesuture part 22 are kept continuous, and the other end of thecollection part 21 is fixedly connected with the base body 1, and the base body 1 is provided with a clampingpart 11 that can be clamped by the biopsy forceps. Asuture needle 3 is detachably installed at the end of thesuture part 22 .

本实施例主要是利用金属缝合线2的螺旋状连续缝合，而且巧妙的宝塔型收缩设计，利用喇叭状的缝合部22去满足大开口的拉拢，并由收拢部21闭合，从而使术口两边黏膜100由拉拢再到逐渐靠拢，将张力较大的手术伤口减张靠拢。这样便可以针对一些相对较大的术口，也可以进行相关的内窥镜缝合，避免外科开腹手术。In this embodiment, the spiral continuous suture of themetal suture 2 is mainly used, and the ingenious pagoda-shaped shrinkage design uses the trumpet-shaped suture part 22 to meet the closing of the large opening, and is closed by theclosing part 21, so that both sides of the surgical opening are closed. Themucous membrane 100 is gradually drawn closer and closer to reduce the tension of the surgical wound with greater tension. In this way, some relatively large surgical openings can be targeted, and related endoscopic sutures can also be performed to avoid surgical laparotomy.

具体操作时，由活检钳夹住基体的夹持部11，通过内窥镜的活检通道将整体进行推送到术口处，使缝合针3探出活检通道，并使缝合针3的针头接触到需要缝合黏膜100。随后，便通过手动转动活检钳，使活检钳顺时针转动之后，将力作用于基体上，使与基体1固定连接的金属缝合线2也随之进行旋转，故在旋转的过程中，缝合针3便会穿入黏膜100，随着继续旋转，其中因为缝合部22呈喇叭状，其端口处的直径相比整体的直径来说更大，所以缝合针3便会在喇叭状的缝合部22的带动下，穿入到另一边的黏膜100内，然后在穿出，满足两个黏膜100之间的跨度缝合。而螺旋状的设计，也将使得缝合针3回转，从而来达到在两个黏膜100之间反复穿设。在反复的旋转后，金属缝合线2便会逐步的穿入术口的黏膜100内，而根据收拢部21（收拢部的具体直径：需满足配套胃肠镜≤3.4mm，配套支气管镜和纤维鼻咽镜≤1.2mm，腹腔镜、关节镜及宫腔镜≤4.5mm，根据所配套的内窥镜活检孔道或腹腔镜腹部皮肤孔道所定，缝合部22的直径较收拢部大1-2mm，使其可以顺利通过内窥镜的活检孔道。）的直径缩小，便会将穿入到此处的黏膜100进行收拢，从而来达到术口缝合的作用。而收拢部21的长度，则根据术口长度而定，需要满足，收拢部21的长度大于术口的长度。当将术口缝合之后，则停止旋转，活检钳脱离夹持，然后将缝合针拆除。使金属缝合线2滞留于术口处，保持术口的收拢，等待术口愈合之后，则拆除金属缝合线2便可。而当需要进行拆线时，则再次由内窥镜进入人体内，并达到金属缝合术口处，用活检钳夹住夹持部11并逆时针旋转，同时向后拉基体1，使螺旋形的缝合部22慢慢退出已经愈合的术口，随后完成拆线步骤，如图4所示。During the specific operation, theclamping part 11 of the base body is clamped by the biopsy forceps, and the whole body is pushed to the operation port through the biopsy channel of the endoscope, so that thesuture needle 3 is protruded out of the biopsy channel, and the needle of thesuture needle 3 is brought into contact with the Themucosa 100 needs to be sutured. Then, by manually rotating the biopsy forceps, after the biopsy forceps are rotated clockwise, a force is applied to the base body, so that themetal suture 2 fixedly connected to the base body 1 also rotates accordingly. Therefore, during the rotation process, thesuture needle 3 will penetrate themucosa 100, and as the rotation continues, because thesuture portion 22 is flared, the diameter of its port is larger than the overall diameter, so thesuture needle 3 will be in theflared suture portion 22. Driven by the slack, it penetrates into themucosa 100 on the other side, and then pierces out to meet the span suture between the twomucosas 100 . The spiral design will also make thesuture needle 3 rotate, so as to achieve repeated penetration between the twomucosas 100 . After repeated rotations, themetal suture 2 will gradually penetrate into themucosa 100 of the surgical port, and according to the specific diameter of the tucked part 21 (the specific diameter of the tucked part: it needs to meet the matching gastroenteroscope ≤ 3.4mm, the matching bronchoscope and fiber Nasopharyngoscope ≤ 1.2mm, laparoscope, arthroscope and hysteroscope ≤ 4.5mm, the diameter of thesuture part 22 is 1-2mm larger than that of the tucked part according to the matching endoscope biopsy or laparoscopic abdominal skin duct. so that it can smoothly pass through the biopsy hole of the endoscope.) The diameter is reduced, and themucosa 100 that penetrates here will be gathered up, so as to achieve the effect of suturing the surgical opening. The length of the foldedportion 21 is determined according to the length of the surgical opening, and needs to be satisfied that the length of the foldedportion 21 is greater than the length of the surgical opening. After the incision is sutured, the rotation is stopped, the biopsy forceps are released from the grip, and the suture needle is removed. Keep themetal suture 2 at the surgical opening, keep the surgical opening closed, and then remove themetal suture 2 after waiting for the surgical opening to heal. When it is necessary to remove the sutures, the endoscope enters the human body again, and reaches the metal suture opening. The clampingpart 11 is clamped with the biopsy forceps and rotated counterclockwise. At the same time, the base body 1 is pulled back to make the spiral Thesuture part 22 of the suture is slowly withdrawn from the wound that has healed, and then the suture removal step is completed, as shown in FIG. 4 .

针对缝合针头3的拆除，是基于记忆金属（采用的是深圳市翔泰记忆新材料有限公司TINI02型医用记忆金属，其性能为：小于30°C时是一种外形状态，当＞50°C时是一种外形状态。当完成缝合并要拆除缝合针头时，仅需要用热活检钳夹住其顶部即可。）受热形变的原理上，使医用合金（强度大且无变形）制成的缝合针3可以轻松脱离针头，达到可拆卸针头。The removal of thesuture needle 3 is based on memory metal (the TINI02 medical memory metal of Shenzhen Xiangtai Memory New Material Co., Ltd. is used, and its performance is: when it is less than 30°C, it is a shape state, when >50°C It is a shape state. When the suture is completed and the suture needle is to be removed, it is only necessary to clamp the top of the needle with a thermal biopsy forceps.) In the principle of thermal deformation, it is made of medical alloy (strong and non-deformable). Thesuture needle 3 can be easily disengaged from the needle to achieve a detachable needle.

具体结构如下：即所述缝合部22位于端头处设置有用于与缝合针3对接的接壤部23，所述接壤部23设置对接端口24，所述对接端口24的端口处开设有夹持臂25，所述夹持臂25为记忆金属，所述夹持臂25的内侧面设置有一插销26，所述缝合针3的尾部开设有一个针孔31并插设于对接端口24内，所述插销26插设于针孔31内，在接壤部23受热之后，其夹持臂25向外展开，使所述插销26脱离针孔31，从而满足缝合针3的拆除。故安装结构，便是采用对接端口24进行对缝合针3尾部的套装，达到初步对装，然后在通过夹持臂25闭合之后，插销26插入与缝合针3的针孔31之内，从而避免缝合针3的抽离，这样便达到锁固。而当需要将缝合针3进行拆除时，则需要通过热活检钳夹持接壤部23处，通过热活检钳的加热，使夹持臂25受热形变，形变方向是向外展开，而一旦夹持臂展开之后，插销26便会脱离缝合针3的针孔31，这样，在外力的作用下，缝合针3便可以抽离对接端口24。The specific structure is as follows: that is, thesuture portion 22 is provided at the end with aborder portion 23 for docking with thesuture needle 3 , theborder portion 23 is provided with adocking port 24 , and the port of thedocking port 24 is provided with a clamping arm. 25.

Therefore, the installation structure is to use thedocking port 24 to fit the tail of thesuture needle 3 to achieve preliminary fitting, and then after the clampingarm 25 is closed, theplug 26 is inserted into theneedle hole 31 of thesuture needle 3, thereby avoiding Thesuture needle 3 is withdrawn, so as to achieve locking. When thesuture needle 3 needs to be removed, theborder portion 23 needs to be clamped by the thermal biopsy forceps, and the clampingarm 25 is heated and deformed by the heating of the thermal biopsy forceps. After the arm is deployed, thelatch 26 will be disengaged from theneedle hole 31 of thesuture needle 3 , so that thesuture needle 3 can be withdrawn from thedocking port 24 under the action of external force.

进一步，本实施例的所述对接端口24的内腔形状与缝合针3尾部形状相对应，而缝合针3尾部的形状优选为棱柱体，这样可以避免自转。且针头为三菱锥或圆锥体，适应不同硬度及柔韧性的组织表面。Further, the shape of the inner cavity of thedocking port 24 in this embodiment corresponds to the shape of the tail of thesuture needle 3, and the shape of the tail of thesuture needle 3 is preferably a prism, which can avoid rotation.
