Description
技术领域 technical field
本实用新型涉及手术器械领域，尤其涉及一种免辅助切口右半结肠标本经肛门取出套管器。 The utility model relates to the field of surgical instruments, in particular to a cannula for removing a right colon specimen through the anus without auxiliary incision.
背景技术 Background technique
腹腔镜辅助经自然腔道取出标本手术(Laparoscopic-assisted natural orifice specimen extraction，LA-NOSE)是传统腹腔镜手术与NOTES手术之间的桥梁。其既保留了常规腹腔镜操作优势又无辅助切口，减少了切口相关并发症。因其腹壁创伤小、减轻术后疼痛、切口美观等潜在优势，已成为近年结直肠外科领域的研究热点。在结直肠外科领域，标本主要经阴道及肛门途径取出。阴道由于其良好的扩张性及愈合能力被某些外科医生所推崇，但是经阴道途径仅适用于女性患者，且涉及正常的非相关器官的损伤，这不仅涉及到伦理问题，经阴道后穹隆途径对术后性生活的影响及潜在阴道直肠瘘也是不可忽视的并发症。相比之下，经肛门取出标本途径更有操作性和优势。标本经肛门取出的LA-NOSE手术主要适应症仍局限在直肠、乙状结肠、降结肠的疾病，右半结肠LA-NOSE手术罕有报道。究其原因，在于右半结肠LA-NOSE手术中结肠远断端与肛门距离远，缺少专用器械辅助取出标本，故造成标本经肛门取出难度系数大，即便勉强使用肠镜辅助拉出标本，也有挤压肿瘤、损伤肠粘膜及撕裂肠管的风险，可操作性小，难以确保手术安全性。 Laparoscopic-assisted natural orifice specimen extraction (LA-NOSE) is a bridge between traditional laparoscopic surgery and NOTES surgery. It not only retains the advantages of conventional laparoscopic operation but also has no auxiliary incision, which reduces incision-related complications. Because of its potential advantages such as less trauma to the abdominal wall, less postoperative pain, and beautiful incisions, it has become a research hotspot in the field of colorectal surgery in recent years. In the field of colorectal surgery, specimens are mainly taken through vaginal and anal routes. The vagina is favored by some surgeons due to its good expansibility and healing ability, but the transvaginal approach is only suitable for female patients, and involves damage to normal non-related organs, which not only involves ethical issues, but the transvaginal posterior fornix approach The impact on postoperative sex life and potential vaginal rectal fistula are also complications that cannot be ignored. In contrast, the method of taking specimens through the anus is more operable and advantageous. The main indications for LA-NOSE surgery with specimens taken through the anus are still limited to diseases of the rectum, sigmoid colon, and descending colon, and LA-NOSE surgery for the right colon is rarely reported. The reason is that the distance between the distal end of the colon and the anus in the LA-NOSE operation of the right colon is far away, and there is a lack of special instruments to assist in taking out the specimen, which makes it difficult to take out the specimen through the anus. The risk of extruding the tumor, damaging the intestinal mucosa, and tearing the intestinal tube is small, and it is difficult to ensure the safety of the operation.
申请号为201410168748.2的中国专利申请《免辅助切口肛门套管器》，公开了一种用于左半结肠、直肠切除术时，免辅助切口完整取出标本的套管器， 但是，对于右半结肠，由于其位置比左半结肠距离肛门的位置远很多，所以，采用该套管器，是无法从右半结肠取出标本的。目前传统腹腔镜右半结肠切除术仍需在下腹部切开4～5cm长的辅助切口用于标本取出。 Application No. 201410168748.2 of the Chinese patent application "Auxiliary Incision Anal Cannula", discloses a cannula used for left hemicolon and rectal resection, which can completely remove the specimen without auxiliary incision. However, for the right hemicolon , because its position is much farther from the anus than the left colon, so it is impossible to take the specimen from the right colon with this cannula. At present, traditional laparoscopic right hemicolectomy still requires an auxiliary incision of 4 to 5 cm in the lower abdomen for specimen removal.
实用新型内容 Utility model content
本实用新型的发明目的在于：针对上述存在的问题，提供一种新的免辅助切口右半结肠标本经肛门取出套管器。 The purpose of the invention of the utility model is to provide a new cannula device for taking out the right colon specimen through the anus without auxiliary incision in view of the above-mentioned problems.
本实用新型采用的技术方案是这样的：一种免辅助切口右半结肠标本经肛门取出套管器，包括内套管、内套管后盖、外套管、外套管后盖和标本拉钩，其中，所述内套管位于所述外套管内，所述内套管的长度大于所述外套管的长度，所述内套管的头端光滑，直径逐渐缩小形成圆台状，所述内套管为软性材质，所述内套管后盖与所述内套管的后端可拆卸连接，所述内套管后盖远离所述内套管的一端设置有开孔，并设置有与所述开孔对应的孔盖，所述外套管后盖与所述外套管的后端可拆卸连接，所述标本拉钩包括直杆段和扣环段，所述直杆段与扣环段的总长度大于内套管的长度。所述内套管、外套管均为两端开放的中空管。 The technical scheme adopted by the utility model is as follows: a cannula device for removing the right colon specimen through the anus without auxiliary incision, including an inner sleeve, an inner sleeve back cover, an outer sleeve, an outer sleeve back cover and a specimen pull hook, wherein , the inner sleeve is located in the outer sleeve, the length of the inner sleeve is greater than the length of the outer sleeve, the head end of the inner sleeve is smooth, and the diameter gradually shrinks to form a truncated cone shape, and the inner sleeve is The back cover of the inner sleeve is detachably connected to the rear end of the inner sleeve, and the end of the inner sleeve back cover away from the inner sleeve is provided with an opening, and is provided with a The hole cover corresponding to the opening, the rear cover of the outer casing is detachably connected to the rear end of the outer casing, the specimen pull hook includes a straight rod section and a buckle section, and the total length of the straight rod section and the buckle section is greater than the length of the inner sleeve.
