Description

Improved biological tissue reclaiming bag

Technical field

This utility model relates to a kind of surgical operating instrument of using when reclaiming biological tissue, particularly is used for reclaiming the reclaiming bag of the biological tissue of excision under endoscope.

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 stay fragment tissue or overflowing liquid in vivo, particularly when excision is organized as the topping ups such as vermiform appendix of gallbladder, cyst, inflammation or during malignant tumor tissue, cause infection easily, lead to complications or cause cancerous tissue diffusion, jeopardize health tissues and 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 reclaiming bags that under endoscope, are used to reclaim excision biological tissue have been developed both at home and abroad.The reclaiming bag of prior art is that an end is open, and the flexible bag-like structure of other end sealing can hold the biological tissue of excision in it.People's such as Bell U.S. Patent No. 5,465,731; People's such as Kammerer U.S. Patent No. 5,480,404 and people's such as Tovey U.S. Patent No. 5,647,372 and people's such as Rousseau U.S. Patent No. 5,971,995 and people's such as S.P. Kang Lun Chinese patent ZL0215153.3, in these patents, disclose a kind of elder generation and the open end of reclaiming bag has been opened, included the biological tissue of excision then in, after biological tissue includes in opening spring, the recovery switch of spring is opened in starting, to open spring and separate, and with the recovery lasso trick on the reclaiming bag open end open end be sealed, and reclaiming bag is taken out external with reclaiming bag.These products have obtained being extensive use of in clinical.These different patents produce technical problem such as wrinkle and have carried out different improvement preventing to open spring respectively with the open accidental separation of reclaiming bag, when avoiding lasso trick sealing open end, and have obtained different patents.The core of the technical scheme of these patents is to have adopted two critical components promptly to open spring and seal lasso trick; Open spring and make reclaiming bag and open spring and separate with opening the open end that spring opens reclaiming bag, withdrawing from, seal with lasso trick, reclaiming bag is taken out external, this basic technical scheme is consistent in these patents.These reclaiming bag complex structures, complex operation costs an arm and a leg, and common patient is difficult to accept.For this reason, the gold hamming has proposed a kind ofly to open the reclaiming bag open end and with reclaiming lasso trick sealing reclaiming bag open end and it being taken out external utility model patent with air bag in Chinese patent ZL01245792.2, because in surgical procedures, when including the biological tissue of excising in reclaiming bag, sometimes need use the open end of surgical instruments clamp reclaiming bag, adopt airbag apparatus may cause the gas leakage or the explosion of air bag, bigger hidden danger is arranged.Liu Fengru has proposed a kind of reclaiming bag that the simple structure of a softish recovery backguy is installed at the bag mouth of softish plastics recovery bag in Chinese patent ZL01232360.8, because the open end of this reclaiming bag does not have the apparatus that opens spring or similar functions, the reclaiming bag bag mouth can not be opened automatically, need under endoscope, bag mouth to be opened by operating theater instruments, then with biological tissue's reclaiming bag of packing into of excision, when biological tissue included in, it was cumbersome to operate, and has prolonged operating time.

In order to overcome the above-mentioned shortcoming of prior art, need improve prior art, provide that structure is simpler, operation is easier, reclaiming bag safely and effectively, at present, still do not have a kind of known biological tissue reclaiming bag and can reach this requirement.

Summary of the invention

Specific embodiment

Fig. 1:

In the present embodiment, the open end of the reclaiming bag of this utility model (1-2) by chemical adhesive be bonded in open and exhausting line (2) on.

The flexible wall (1-1) of reclaiming bag (1) has adopted the composite construction of the enhanced flexible high molecular material of memorial alloy fleece (9) (10), in vivo, because the effect of body temperature, memorial alloy fleece (9) recovers super-elasticity, make the flexible wall (1-1) of reclaiming bag keep the softish while, appropriate elasticity is arranged, be convenient to include in the biological tissue (3) of excision.

In the present embodiment open and exhausting line (2) can adopt the shape-memory alloy wire manufacturing, as adopting niti-shaped memorial alloy silk or the thin copper base shape memory alloy wire manufacturing of plating.During manufacturing, earlier niti-shaped memorial alloy silk or the thin copper base shape memory alloy wire of plating are passed through the typing heat treatment, make it more than recovery temperature, have one section open end (1-2) that the shape that is complementary is arranged, promptly obtained opening and exhausting line (2) with reclaiming bag.

To make good open end (1-2) with the enhanced reclaiming bag of memorial alloy fiber (9) then is bonded in opening of memory alloy wire manufacturing and exhausting line (2) by chemical adhesive and has on one section memory alloy wire of the shape that is complementary with the open end (1-2) of reclaiming bag.At last the two ends of memory alloy wire are fixed on the far-end (4-1) of interior sheath (4), can have obtained the improved biological recovery bag of this utility model.

When clinical use, the reclaiming bag (1) that will be compressed in this utility model in the epitheca (5) discharges, under the effect of body temperature, open and the rapid geometry of recovering setting of exhausting line (2), launch the open end (1-2) that drives flexible reclaiming bag, be convenient to include in the biological tissue (3) of excision under the endoscope, with the excision biological tissue (3) include reclaiming bag (1) in after, inwardly sheath handle (4-2) extreme direction returns and removes interior sheath (4) or epitheca (5) is sent forward along interior sheath (4), can hyperelastic opening and exhausting line (2) compression will be had, the flared end (1-2) that drives reclaiming bag is recovered in the epitheca (5) again, takes out external.At this moment the biological tissue (3) of excising in the reclaiming bag (1) is if not too big, can be fully retrieved in the epitheca (5), take out external, if the biological tissue (3) of excision is too big, to open and the open end (1-2) of the reclaiming bag that exhausting line (2) drives is fully retracted into epitheca (5) when interior, the flared end of reclaiming bag (1-2) base closed can move to the reclaiming bag (1) that excision biological tissue (3) is housed near the otch safely, and is external with taking out after the surgical instruments fragmentation.With reference to figure 5, Figure 10, Figure 12.
