Description

Improved biological tissue recovery bag

FIELD

The present invention relates to surgical instruments used when recovering a biological tissue, particularly in endoscopic resection recovery bag for recovering the biological tissue.

Background technique

Endoscopic surgery is performed through small incisions minimally invasive surgery, which reduces or eliminates the large surgical incision, so that similar cholecystectomy, myomectomy other major open surgery becomes a simple outpatient procedure, the patient's recovery time from weeks to days, which has been more widely used.

In implementing such procedures, a biological tissue resected if too large, can not be removed through a small incision, the incision must be enlarged, these biological tissue is removed, thus greatly reducing the advantages of endoscopic surgery; Another method , the surgical instrument in vivo by the biological tissue is cut into chunks suitable for either small piece of tissue removed through a small incision, but this method, fragments may be left in the body tissue or spillage, especially when removal of tissue, such as filling the gallbladder, cyst, inflamed appendix, etc. or malignant tissue, easily lead to infection, causing complications or lead to cancer spread, endangering the health and safety organization.

To address this constraint chunk of biological tissue through a small incision and safely remove the removal of endoscopic surgery developed technical problems, at home and abroad to develop a variety of recycling bags for recycling in endoscopic resection of biological tissue. Prior art recovery bag is open at one end, the other end of the flexible bag-like closed structure, which can hold the biological tissue excised. B) ell et al., U.S. Patent No.5,465,731; KA) mmerer et al., U.S. Patent No.5,480,404 and U.S. Patent No.5,647,372 Tovey et al., And U.S. Patent No. RousseA) u et al., No. 5,971,995 and SP Conlon et al. Chinese Patent ZL0215153.3, disclosed in these patents with the open end of a prior open spring flared recovery bag, and then cut into the biological tissue, the biological tissue into, starter spring recovery switch open, the opening spring and the recovery bag was separated, recycled lasso recovery bag open end of the open end is closed, and the recovery bag unloading vitro. These products have been widely used in the clinic. These patents are different in the spring and the opening to prevent accidental separation recovery bag is open, to avoid the open end of the closed sling when wrinkles or the like of the technical issues various modifications, to obtain a different patents. The core aspect of these patents is the use of two key components i.e. opening and closure springs lasso; flared recovery bag with an open end opening spring, opening the withdrawal of the recovered bag and the opening spring spring separator, with lasso sealing, the bag unloading recovered vitro, the basic technical solutions in these patents are consistent. The recovery bag structure complicated, cumbersome operation, expensive, difficult to accept ordinary patients. To this end, Jin Haiming proposed in Chinese Patent No. ZL01245792.2 airbag opening in the open end of the bag and the recovered from recycled lasso closing the open end of the bag and the recovery utility patent vitro remove it, since the surgical operation, when cutting a biological tissue into the recovery bag, and sometimes required surgical instrument jaws recovery bag open end, the airbag device using the airbag may cause leakage or explosion, greater risks. Liu Fengru recovery bag made simple structure for mounting a flexible cable in a recovery bag of flexible plastic recovery bag in Chinese Patent ZL01232360.8, since the open end of this recovery bag without opening a spring or functionally similar instrument, pocketed recovery port does not automatically open, the need to open the bag by the endoscopic surgical instrument, and then excised biological tissue recovery bag was charged, when a biological tissue into operation more trouble, extended operation time.

To overcome the above disadvantages of the prior art, the need for improvement over the prior art, providing a simpler structure, easier to operate, safe and effective recovery bag, at present, no known biological tissue to reach the recovery bag Claim.

SUMMARY

The present invention provides a patient recovered from excised biological tissue recovery bag, the core technology is the recovery bag at the open end of a recovery bag opening and the recovery line is installed, both in the open and the recovery line recovery bag open play function recovered the bag open end of the release, but also play a role in the recovery of the seal of the bag recycling.

Improved biological tissue according to the present invention, recovery bag, and the bag opening comprising recovering and recycling line, recovery bag by a flexible wall, an open end, a closed end composition, the bag may be recycled to receive a biological tissue;

Shape of the open end A) containing the opening and the recovery period and the recovery bag line matches a line segment;

B) recovering an open end of the bag open end is connected to the line and a recovery line with the flared shape recovery bag matches.

- said spreading and recovery line shape memory alloy wire or shape memory alloy sheet manufacture may be used, may be made of alloy spring steel, or other deformed shape capable of storing, when released, will be able to close back to the original or any material manufacturing original shape.

- on the open end of the line is connected to the recovery bag opening and a recovery line open end shaped to match the recovery bag, can be slidably connected to may be a fixed connection, such as:

A. flared recovery line and may slide within the slot of the recovery bag open end;

B. open a certain period and the recovery line is secured to the open end of the slot of the recovery bag, can not move, and the other opening portion of the recovery line may slide within the slot of the open end of the recovery bag; bag open recovered C. and the open end may be adhered to the recovery line by a chemical adhesives;

D. flared recycling bags to be set in open and recycling line.

- the collection bag may be a flexible Gao flexible wall material of the molecule, a metal mesh or a synthetic fiber reinforcement for producing a flexible polymer material may also be employed, such as silicone rubber may be employed, polyurethane, polyethylene, polypropylene, silicon resin, vinyl resin or polytetrafluoroethylene elastomeric polymer material or manufacturing; memory alloy may also be used synthetic fibers or mesh reinforced silicone rubber, polyurethane, polyethylene, polypropylene, a silicone resin, a vinyl resin polytetrafluoroethylene or an elastomeric material or a polymer.

- said spreading and recycling lines can be connected to the distal end of the inner sheath, the distal end of the inner sheath before the installation, within the distal end of the outer sheath.

- the relative position of the inner sheath and the outer sheath, may be fixed by the positioning knob.

- opening and above the recovery line can be released from the distal end of the inner sheath, in vitro direct access; or form a closed loop or slipknot removed with a surgical instrument through the body.

- the open end of the collection pouch may be coated with the biological tissue under observation of the endoscope to have significantly different colors.

- opening above the inner sheath and the recovery line was a certain radial plane of curvature of the arc type.

- the above-mentioned opening end of the recovery line and may be a slip knot, the other end through the slot from the open end of the recovery bag, and then through the slipknot lariat structure formation.

Since the present invention is recovered at the open end of the bag opening and a recovery line installation, opening and open both play a recovery line recovery bag open end of the bag in the recovery function is released, but when the recovery bag sealing functions recovery the role of simple structure, easy to operate, safe and effective.
