Description
Technical field
The present invention relates to a kind of micro-wound surgical operation apparatus, particularly minimally invasive surgery such as peritoneoscope, thoracoscope takes out the apparatus of resection organization.
Background technology
Chamber mirror surgical operation is the Minimally Invasive Surgery of finishing by little otch, and this class operative incision is little, postoperative patient pain light, it is fast to recover, thereby has obtained application more and more widely.But when implementing this type of operation, how safely the bulk biological tissue of excision being taken out by little otch, is the difficult problem that chamber mirror minimally invasive surgery runs into when further developing; Particularly when excision is organized as the topping ups such as vermiform appendix of gallbladder, cyst, inflammation or during malignant tumor tissue, remain in intravital fragment tissue or overflowing liquid, cause easily infecting, lead to complications or cause the plantation diffusion of cancerous cell, jeopardize other health tissues, even patient's life security.
In order to solve by little otch safely this restriction chamber mirror surgical operation Development Technology difficult problem of the bulk biological tissue that takes out excision, the various operating theater instruments that are used to take out the biological tissue of excision have been developed both at home and abroad.The operating theater instruments of the taking-up resection organization of prior art has two big classes, and a class is the biological sample destroyer, and a class is the specimen reclaiming bag.The biological sample destroyer of prior art is by in the rotation cutting of intraperitoneal to the biological sample of excision, with the bulk biological sample cut into behind the fritter by little otch take out carry outside, comparatively practical to the benign tumors that does not contain liquid tissue.The liquid of fine tissue or the topping up tissue residual plantation diffusion that causes infecting or causing cancerous cell in vivo when cutting for avoiding rotating, the biological sample destroyer clinically usually and the specimen reclaiming bag be used, promptly earlier include biological sample in the specimen reclaiming bag, then with the fragmentation of biological sample destroyer and take out external.
The specimen reclaiming bag of prior art has two classes, and a class is the specimen reclaiming bag that band opens spring, and another kind of is not to be with the specimen reclaiming bag that opens spring.Band opens the specimen reclaiming bag of spring, as U.S. Patent No. 5,465, and 731, No.5,480,404, No.5,647,372, No.5,971,995, this class reclaiming bag is that an end is open, the flexible bag-like structure of other end sealing.The specimen reclaiming bag is installed in the front end of the delivery system of being made up of interior sheath and epitheca, after delivery system enters human body, return and remove epitheca, the specimen reclaiming bag is exposed, in vivo the open end of reclaiming bag is opened by surgery speculum, and with the excision biological tissue include in the bag, remove the spring that opens of speculum then, reclaiming bag is separated with speculum, strain the lasso trick that seals of reclaiming bag open end, the reclaiming bag open end is sealed, take out biological tissue external then or move near the otch externally with taking out after the surgical instruments fragmentation, complex structure is operated loaded down with trivial details, the use cost height, because of economic cause, a lot of patients are difficult to bear, and the reclaiming bag of thin film fabrication is stuck between interior sheath and the epitheca easily simultaneously, frictional resistance increases, and not only is difficult to discharge but also cause sometimes the reclaiming bag breakage.Be not with and open spring specimen reclaiming bag, as Chinese patent ZL0215153.3, ZL01245792.2, ZL01232360.8, bag mouth can not be opened automatically, need to open with operating forceps in vivo, waste time and energy, select for use the food fresh keeping bag to compare with doctor oneself, no clear superiority, clinical being difficult to promotes.Shortcoming for the said goods, the inventor once designed specimen reclaiming bag (the Chinese patent ZL03146816.0 that has produced a series of band deploying devices, ZL03274546.X, ZL03146815.2, ZL03274545.1, ZL200310111814.4, ZL200320117106.7, ZL200410052301.5, ZL200420095393.0), and good application arranged clinically, but the delivery system of these specimen reclaiming bags has still adopted traditional interior epitheca formula structure, in large-scale clinical practice, still exist the reclaiming bag of thin film fabrication to be stuck in easily between interior sheath and the epitheca, frictional resistance increases, and not only is difficult to discharge but also cause sometimes the phenomenon of reclaiming bag breakage.
These specimen reclaiming bags of the prior art, all adopted the induction system that the specimen reclaiming bag is compressed between interior sheath and the epitheca to discharge, because reclaiming bag is not easy to put into the epitheca pipe after folding, production efficiency is low, simultaneously, in clinical use, in being stuck in easily, the flexible material thin film of reclaiming bag between sheath and the epitheca, increased resistance, be difficult for discharging, sometimes also can cause the reclaiming bag breakage, particularly for the big specimen reclaiming bag of volume, this shortcoming is more obvious.
In order to overcome the above-mentioned shortcoming of prior art, provide an easier release in clinical use, production efficiency higher, safer, therefore the specimen reclaiming bag that price is cheaper need improve prior art.
