腹腔镜肾部分切除术用手术缝合针Surgical needles for laparoscopic partial nephrectomy

技术领域technical field

本发明涉及手术器械技术领域，尤其涉及一种腹腔镜肾部分切除术用手术缝合针。The invention relates to the technical field of surgical instruments, in particular to a surgical suture needle for laparoscopic partial nephrectomy.

背景技术Background technique

现有技术中的腹腔镜肾部分切除术已成为治疗早期肾肿瘤的主要手术方式，其具有手术创伤小，恢复快，能最大保存肾功能等优势。但是，腹腔镜肾部分切除术手术操作空间有限，缝合跨度大，借助目前常规缝合针在腹腔镜下缝合操作复杂，打结困难，缝合不确切，往往增大了手术的操作难度，限制了手术的开展。同时目前常规泌尿外科缝合针长度均较短，无法彻底贯穿肾脏前后径，使缝合时无法确切缝合肾组织；目前常规缝合针弧度过大，肾缝合时不易贯穿出针。Laparoscopic partial nephrectomy in the prior art has become the main operation method for the treatment of early renal tumors. It has the advantages of less surgical trauma, faster recovery, and maximum preservation of renal function. However, the operating space of laparoscopic partial nephrectomy is limited, and the suture span is large. With the help of conventional suture needles, the suture operation under laparoscopy is complicated, knotting is difficult, and suture is inaccurate, which often increases the difficulty of the operation and limits the operation. development. At the same time, the current conventional urological suture needles are short in length and cannot completely penetrate the anteroposterior diameter of the kidney, making it impossible to accurately suture the kidney tissue during suturing; the current conventional suture needles are too large, and it is difficult to penetrate the needle during kidney suture.

具体实施方式Detailed ways

下面结合附图与实施例对本发明做进一步说明。The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

一种腹腔镜肾部分切除术用手术缝合针，结合图1，图2，包括针体1、缝线2，针体通过针尾与缝线连接，针尾与缝线为一体的紧密连接结构、采用无创伤连接，针体的针尖为圆形针尖，针体采用弧形结构，所述手术缝线末端设有阻挡器3，所述阻挡器与缝线固定一体。针体采用圆弧形结构，弧度为120°(即1/3弧度)，弦长为6cm。适用于缝合时进针出针，即可充分贯穿肾脏，又避免了过长所造成的使用不便。缝合针应与缝合线一体，为无创伤缝合针，更加便于手术操作。A surgical suture needle for laparoscopic partial nephrectomy, combined with Figure 1 and Figure 2, includes aneedle body 1 and asuture 2, the needle body is connected to the suture through the needle tail, and the tight connection structure of the needle tail and the suture is integrated , Using non-invasive connection, the needle point of the needle body is a round needle point, the needle body adopts an arc structure, the end of the surgical suture is provided with astopper 3, and the stopper and the suture are fixed together. The needle body adopts a circular arc structure with a radian of 120° (that is, 1/3 radian) and a chord length of 6cm. It is suitable for the insertion and exit of the needle during suturing, which can fully penetrate the kidney, and avoids the inconvenience caused by too long. The suture needle should be integrated with the suture thread, which is an atraumatic suture needle, which is more convenient for operation.

缝线长度为10cm，缝线采用复合缝线材料。缝线采用PGLA(910聚乙交酯-丙交酯)材料制成，缝线长短适中，长度满足腹腔镜手术的需要。The suture length is 10cm, and the suture is made of composite suture material. The suture is made of PGLA (910 polyglycolide-lactide) material, the suture length is moderate, and the length meets the needs of laparoscopic surgery.

所述阻挡器采用不可吸收的医用多聚合物材料。所述阻挡器采用长方体薄片结构，所述缝线与长方体薄片垂直。The barrier is made of non-absorbable medical multi-polymer material. The blocker adopts a cuboid sheet structure, and the sutures are perpendicular to the cuboid sheet.

所述缝线在缝合、收紧后，通过hem-o-lok夹将缝线夹闭。通过hem-o-lok夹使缝线起到缝合作用，避免了腹腔镜下复杂打结操作。采用常规hem-o-lok组织夹，避免了撕扯肾组织、起到充分固定作用，又避免了体积过大影响手术操作。After the sutures are sutured and tightened, the sutures are clipped by hem-o-lok clips. The hem-o-lok clip is used to make the suture suture, which avoids the complicated knotting operation under the laparoscope. The use of conventional hem-o-lok tissue clips avoids tearing of the kidney tissue, fully fixes it, and avoids the effect of excessive volume on the operation.

本发明在行肾脏等深部较厚组织缝合时，能够较容易贯穿组织纵径以充分缝合组织，末端阻挡器起锚状固定作用，缝合后只需将缝线收紧以hem-o-lok夹夹闭缝线即可起到缝合作用，避免了腹腔镜下复杂打结操作。The present invention can easily penetrate through the longitudinal diameter of the tissue to fully suture the tissue when suturing the thicker deep tissue such as the kidney, and the end stopper acts as an anchor-like fixation. Closed sutures can be sutured, avoiding complicated knotting operations under laparoscopy.

上述虽然结合附图对发明的具体实施方式进行了描述，但并非对本发明保护范围的限制，在本发明的技术方案的基础上，本领域技术人员不需要付出创造性劳动即可做出的各种修改或变形仍在本发明的保护范围以内。Although the specific implementation of the invention has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the present invention. On the basis of the technical solution of the present invention, those skilled in the art can make various Modifications or variations are still within the protection scope of the present invention.
