Description

—种腔镜用组织取出袋 - Species endoscopic tissue retrieval bag with

技术领域 FIELD

[0001] 本发明涉及一种用于在进行腔镜手术时取出内部组织的腔镜用组织取出袋,属于医用器械技术领域。 [0001] The present invention relates to an internal mirror A method for removing tissue during a laparoscopic surgery for tissue retrieval bag, belonging to the technical field of medical instruments.

背景技术 Background technique

[0002] 腔镜手术是一种通过小切口完成的微创手术,由于其具有创伤小、出血少、恢复快等优点,给手术患者带来了福音,越来越多的手术可以在胸或腹腔镜下完成,目前已经广泛应用在胸外科、普外科、肝胆科和妇科等手术领域。 [0002] Endoscopic surgery is a minimally invasive done through a small incision surgery, because it is less invasive, less bleeding, quick recovery, a boon to surgical patients, surgery may be more or chest completion of laparoscopic surgery has been widely applied in the field of thoracic surgery, general surgery, hepatobiliary and gynecology department. 而对于此类手术来说,如何在胸或腹腔镜手术中将切除的组织或局部器官组织安全顺利地从患者体内取出而不造成切口污染已经成为手术的一个重要环节。 For such procedures, how the chest without causing or laparoscopic surgery in the local tissue or organ tissue safe and smooth removal from the patient incision pollution has become an important part of the operation.

[0003] 针对此问题,传统的做法是利用无菌手套或灭菌生理盐水袋进行适当的裁剪和调整后做成袋子,在手术过程中,将袋子从切口放入胸或腹腔,腔内用多把钳子反复钳夹牵扯袋子的袋口边沿,将袋口撑开才可将切除的组织装入袋子,程序繁琐,耗时久,医者操作不便,甚至耽误抢救患者的宝贵时机.还可能因术中操作不当导致肿瘤细胞脱落并残留。 [0003] For this problem, a conventional approach is the use of sterile gloves, or sterile saline bag cutting and appropriate adjustments made after the bag, during surgery, the incision from the bag into the chest or abdominal cavity, with the cavity multi-jaw pliers repeatedly dragged the bag edge of the bag, the bag distraction before the excised tissue in a bag, cumbersome procedures are time-consuming, inconvenient operation healer, and even delay the valuable opportunity to rescue patients. may also be due intraoperative tumor cells resulting in improper operation and remains off. 后来有在此基础上的改进,其将袋口与钳子的两个开合端绑扎在一起,使用时,操作上述钳子将袋口撑开或闭合,操作相对简单,但由于需要取出的组织在一定深度处,钳子在开合时会撑到创口,实用性差。 Later improvements on the basis of which the binding pocket with two ends with the opening and closing of the forceps, in use, operation of the distraction forceps or mouth of the bag closed, the operation is relatively simple, but because of the need to remove tissue at a certain depth, the opening and closing of the forceps will hold the wound, practical difference.

[0004] 针对上述缺陷,市场上出现了一些解决方案,如中国发明专利CN200420005648.X公开了一种自动开口式腹腔镜手术标本袋,但其存在整体结构复杂,操作繁琐,且耗时久的缺点。 [0004] For the above disadvantages, there are some solutions on the market, such as China patent discloses an automatic opening CN200420005648.X laparoscopic surgical specimen bags, but there is a complex overall structure, complicated operation, and the long time-consuming shortcomings. 美国专利US5480404公开了一种先用张开弹簧将袋体打开,装入切除的组织后,启动张开弹簧的回收开关,将张开弹簧与袋体分离,撤除张开弹簧,使用袋体袋口上的套索封闭袋口,并将袋体拉出件外,这种袋体虽可方便快速的打开袋口,但是构造过于复杂,操作繁琐,价格昂贵,令普通患者难以接受。 U.S. Patent US5480404 discloses a spring to open the bag with the open, after loading the tissue removal, recovery switch starts opening spring, the spring will open the bag separation, removal opening spring, using the bag pockets noose on opening the bag closed, the bag was pulled out of the outer body, although such a pouch can be easily opened pocket quickly, but the structure is too complicated, cumbersome operation, expensive, difficult to accept so that the average patient.
