Abstract
The present invention relates to a composite structure which is formed by means that flexible material (6) is used for coating shape memory alloy wires or a shape memory alloy silky fiber net (5) on the opening end (2) or the flexible wall (4) of a recovery bag. After the recovery bag (1) enters a human body, the opening end (2) of the recovery bag can be automatically opened under the action of human body temperature, which is convenient to the introduction of cut biotic tissues. The composite structure has the advantages of simple structure, easy operation, safety and efficiency.
Description
Technical field
The present invention relates to a kind of surgical operating instrument of using when reclaiming biological tissue, particularly under endoscope, be used for reclaiming the reclaiming bag of the biological tissue of excision.
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 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 adopt to have made two critical components and promptly 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 biological tissue's bag of excision is gone into reclaiming bag, when biological tissue includes in, operate cumbersomely, 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
The invention provides a kind of reclaiming bag that reclaims the biological tissue of excision in patient's body, the core technology of this reclaiming bag is in the open end 2 of reclaiming bag or flexible wall 4 composite construction that adopted flexible material 6 wrapped shapes memory alloy wires or shape memory alloy wire fleece 5 to form, after reclaiming bag 1 enters in the body, under the effect of body temperature, the open end 2 of reclaiming bag can be opened automatically, is convenient to include in the biological tissue of excision.
Novelty of the present invention is:
Self-inflated biological tissue reclaiming bag has a flexible wall 4, open end 2, blind end 3, receivability biological tissue 13 in the reclaiming bag 1; It is characterized in that: the open end 2 of reclaiming bag or flexible wall 4 are composite constructions that flexible material 6 wrapped shapes memory alloy wires or shape memory alloy wire fleece 5 form.
---above-mentionedly state shape-memory alloy wire or shape memory alloy wire fleece 5 also can adopt alloy spring steel, or other can store the shape after the distortion, when unclamping, just can get back to primary or near any material manufacture of primary shape.
---the open end 2 of above-mentioned reclaiming bag 1 can install back take-up 7, and exhausting line 7 can be to be slidingly connected with being connected of open end 2 of reclaiming bag 1, also can be fixedly connected, as:
A) exhausting line 7 can slide in the slotted eye 11 of the open end 2 of reclaiming bag;
B) on the slotted eye 11 of a certain section of exhausting line 7 open end 2 that is fixed on reclaiming bag, can not move, other parts of exhausting line 7 can be slided in the slotted eye 11 of the open end 2 of reclaiming bag;
C) open end 2 of reclaiming bag can be bonded on the exhausting line 7 by chemical adhesive;
D) flared end 2 of reclaiming bag can be embedded on the exhausting line 7.
---in above-mentioned exhausting line 7 can be connected on the far-end 8-1 of sheath, in being installed in before the far-end 8-1 of sheath, in the far-end 9-1 of epitheca.
---the relative position of above-mentioned interior sheath 8 and epitheca 9 can fix by navigation button 10.
---the open end 2 of above-mentioned reclaiming bag can scribble with endoscope under observed biological tissue 13 visibly different color is arranged.
The composite construction that the present invention has adopted flexible material 6 wrapped shapes memory alloy wires or shape memory alloy wire fleece 5 to form owing to open end 2 or flexible wall 4 at reclaiming bag, after reclaiming bag 1 enters in the body, under the effect of body temperature, the open end 2 of reclaiming bag can be opened automatically, be convenient to include in the biological tissue of excision, simple in structure, easy and simple to handle, safe and effective.
