Abstract
The present invention relates to combined biological specimen recovering and treating device used, especially, in endoscope operation. The combined biological specimen recovering and treating device includes recovering bag and delivering unit. The recovering bag has opening springs connected to its opened end and connecting head connected to the opening springs, and the connecting head is matched mechanically and detachably with the connecting rod in the delivering unit. The present invention makes it possible to take out relatively large biological specimen with recovering bag in proper size in endoscope operation. The recovering bag may be transferred to the delivering unit with the transferring casing. The delivering unit may be sterilized and reused, while the recovering bag and the transferring casing are disposable.
Description
Technical field
The present invention relates to a kind of surgical operating instrument, particularly at the endoscopic surgery biological sample retracting device of midwifery thing specimen next time.
Background technology
Endo-surgical 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 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 endo-surgical Development Technology difficult problem of the bulk biological tissue that takes out excision, the various specimen reclaiming bags that are used to reclaim the biological tissue of excision have been developed both at home and abroad.The reclaiming bag of prior art has two big classes, and a class is that band opens the specimen reclaiming bag of spring, and another kind of is the simple and easy reclaiming bag of not being with the bag mouth that opens spring specimen reclaiming bag not open automatically.Band opens the specimen reclaiming bag of spring, as U.S. Patent No. 5,465,731, 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, 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, with reclaiming bag open end sealing, take out biological tissue external then or move near the otch external with taking out after the surgical instruments fragmentation, complex structure, operate loaded down with trivial details, the use cost height, because of economic cause, a lot of patients are difficult to bear.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.
In order to overcome the above-mentioned shortcoming of prior art, need improve prior art, safer, easy to operate, a cheap biological sample reclaiming bag is provided, at present, still do not have a kind of known biological sample reclaiming bag and can reach this requirement.
Summary of the invention
The object of the present invention is to provide a kind of combined bio specimen recycling and processing device, can in endo-surgical, pass through little otch, take out the bulk biological tissue specimens of excision safely, and can be according to the size of the specimen of excision, select the specimen reclaiming bag of suitable specification, be installed in before reclaiming bag uses and shift in the sleeve pipe, utilize the transfer sleeve pipe easily reclaiming bag to be transferred on the delivery device, and be delivered to the biological sample that reclaims excision in the body.
Combined bio specimen recycling and processing device of the present invention, comprise reclaiming bag and delivery device, the spring wire that opens on the reclaiming bag is connected with the open end of reclaiming bag, and the silk head that opens spring wire is connected on the union joint, and union joint forms dismountable machinery with connecting rod on the delivery device and cooperates.
---it is the concavo-convex mode that is connected that the union joint on the described reclaiming bag and the connecting rod on the delivery device form that dismountable machinery cooperates, perhaps thread connecting mode, perhaps sunk screw, perhaps alignment pin connected mode.
