Description
Technical field
The present invention relates to a kind of surgical operating instrument of using when reclaiming biological tissue, the protective cover of the reclaiming bag of using when particularly under endoscopic surgery, reclaiming the biological tissue of excision with reclaiming bag.
Background technology
Endo-surgical is the Minimally Invasive Surgery of finishing by little otch, this modus operandi has reduced or eliminated big otch, make that being similar to great opening surgical operations such as gallbladder removal, resection of uterine leiomyoma has become simple outpatient operation, patient's convalescent period from several weeks shorten to several days, thereby have obtained application more and more widely.
But when implementing this type of operation,, can't take out, must enlarge otch, these biological tissues are taken out, so just reduce the superiority of endo-surgical greatly by little otch if the biological tissue of excision is too big; Another kind method is, pass through surgical operating instrument in vivo, the bulk biological tissue of excision is divided into the little block organization that some are adapted to pass through little otch taking-up, but when adopting this method, may residual in vivo fragment tissue or overflowing liquid, particularly when excision is organized as the topping ups such as vermiform appendix of gallbladder, cyst, inflammation or during malignant tumor tissue, cause easily infecting, lead to complications or cause cancerous tissue diffusion, jeopardize other health tissues, even patient's life security.
In order to solve by little otch this restriction endo-surgical Development Technology difficult problem of taking out the bulk biological tissue of excision safely, the various apparatuses that are used to reclaim excision biological tissue have been developed both at home and abroad.Mainly contain two classes, a class is biological tissue's destroyer, and another kind of is biological tissue's reclaiming bag.The destroyer of prior art, cutter head by rotation, bulk biological tissue is broken for can be external or external by the suction pipe sucking-off by the fritter biological tissue taking-up of little otch, but this class apparatus is to use at open state, organize fragment or tissue fluid meeting in vivo residual, cause easily infecting, lead to complications or cause the cancerous tissue diffusion, as the technology of Chinese patent ZL97233972.8 bulletin.The reclaiming bag of prior art is that an end is open, the flexible bag-like structure of other end sealing, in vivo the open end of reclaiming bag is opened by surgery speculum, and the biological tissue of excision is included in the bag, remove the spring that opens of speculum then, reclaiming bag is separated with speculum, tension reclaiming bag open end seal lasso trick, with the sealing of reclaiming bag open end, take out biological tissue external then or move near the otch external with taking out after the surgical instruments fragmentation, as Chinese patent ZL0215153.3, ZL01245792.2, ZL01232360.8, U.S. Patent No. 5,465,731, No.5,480,404, No.5,647,372, No.5,971,995.Owing to by sealing the opening that lasso trick can't the complete closed reclaiming bag, cause the seepage of tissue fluid, cause infection; Perhaps, the biological tissue after the excision is too big, can't take out by little otch and take out near maybe can't moving to little otch, or in pulling process normal structure be caused damage.At this moment, need in reclaiming bag, biological tissue to be carried out fragmentation earlier, and then move to little otch and take out, because destroyer is worked in open reclaiming bag, may cause broken fritter biological tissue or tissue fluid to be overflowed from the open end of reclaiming bag, cause infection, lead to complications or cause cancerous tissue diffusion.
