Abstract

The utility model provides a degradable lumen closing clamp, belongs to the technical field of biological medicine, and particularly relates to a biological degradable surgical medical consumable item used for clamping, closing and cutting lumen structures such as blood vessels, cystic ducts and ureters. The degradable lumen closing clamp is characterized in that a clamp body is in a flexible long-strip shape and can be folded and closed, the closing face of the clamp body is provided with clamping teeth capable of being mutually matched in a staggered mode, one end of the closing face is provided with a cylindrical clamping groove, the other end of the closing face is a clamping hammer capable of entering the cylindrical clamping groove, and accordingly the lumen closing clamp is formed. The degradable lumen closing clamp has the advantages that good biocompatibility is achieved, and in-vivo degradation can be achieved; in terms of the structure, protective and easy-to-operate design is achieved, accordingly the situation that in the use process, target organs are harmed accidentally is avoided, and the degradable lumen closing clamp can be easily in a clamping state and is firm in clamping; the degradable lumen closing clamp is a promising auxiliary surgical tool.

Description

A kind of degradable obliteration folder

Technical field

This utility model relates to biological medicine technology field, specifically for the luminal structures such as blood vessel, cystic duct, ureter are pressed from both sides to the biodegradable operation medical disposable material that closes cut-out.

Background technology

Along with the development of thoracoscope and laparoscopic instrument, Wicresoft's endoscope-assistant surgery has also obtained development in an all-round way in recent years, and this type of operation is used widely in a plurality of section office such as thoracic surgery, department of general surgery, department of obstetrics and gynecology, Urology Surgeries.Wicresoft's endoscope-assistant surgery has that wound is little, pain is light, go out insufficiency of blood, short superiority of hospital stays, and the high praise that has therefore not only obtained doctor has also obtained patient's approval.Except patients with terminal, Wicresoft's endoscope-assistant surgery will progressively replace traditional operation becomes operating main flow trend.

The development of Wicresoft's endoscope-assistant surgery has benefited from the development of chamber mirror necessary accessories to a great extent, as high-definition camera, nipper, wire twister, vessel sealing device, ultrasound knife etc.Chamber mirror necessary accessories are divided into operating equipment and operation consumptive material.Operation consumptive material is mainly assisted for organize closed with from disconnected, as ligation such as blood vessel, cystic duct, ureters with from disconnected etc.In traditional operation, the closure of this type of luminal structure from disconnected be all by suture ligature carry out later shears from disconnected, although less expensive, extended the operating time, and often need under the assisting of larger otch, complete.In endoscope-assistant surgery, utilize the method for traditional suture ligature more consuming time, effect is imprecise, therefore often need succedaneum to carry out closure and from disconnected.Be directed at present the trunks such as pulmonary artery, pulmonary vein often by straight cuts device (as the ATW45 of Johnson & Johnson 35mm blood vessel cutting closed) complete, but for little blood vessel because thereby blood vessel is meticulous so can cause stitching entirely not occur that blood vessel leaks blood, what therefore clinical practice was at present more is that titanium folder and hemolok press from both sides.It is firm that Hemolok clamp holds, but it must overlap blood vessel completely and carry out ligation, cause carrying out when ligation is cut off completing for some completely not free blood vessel, it easily easily comes off in ligation process from hemolok pincers simultaneously, therefore also has technically certain defect; At material in essence, be that titanium folder or hemolok folder are all degradable materials not, so long-term existence often easily cause seroma, foreign body reaction etc. in body.

Summary of the invention

This utility model provide luminal structures such as being applicable to medium and small blood vessel, cystic duct in human body in Wicresoft's endoscope-assistant surgery situation from disconnected, it is firm that it is easy to use, folder closes, can tube chamber be implemented thorough closure and be carried out from disconnected, and can be degradable in vivo, make it in the situation that guaranteeing short term efficacy, not produce a kind of biodegradable obliteration folder of side effect at a specified future date.

The technical scheme that this utility model is taked::

A kind of degradable obliteration folder, comprises clamp, and its scheme is: clamp is flexible strip shape, can doubling closed; On the closing face of clamp, have the closed latch that can misplace mutually, there is cylindric draw-in groove end, and the other end is the card hammer that enters cylindric draw-in groove, whole formation obliteration folder; Described obliteration folder, its integral body is made by degradation material.

The good effect of implementing after this utility model is:

Owing to having used the degradation materials such as polycaprolactone, so this repair materials is for the good biocompatibility of tissue, and has preferably suitable degradation speed, completes vivo degradation in the situation that guaranteeing enough mechanical strengths; Structurally, done the design of protectiveness and easy operating, made it in use avoid occurring that accidental injury target organ closed clamp are easy to enter clamp position, clamping firmly; It is a rising assisted surgery instrument.

Accompanying drawing explanation

State perspective view is held together in Fig. 2 obliteration clamping.

The specific embodiment

Now the utility model is described in further detail by reference to the accompanying drawings

A kind of degradable obliteration folder, comprises clamp, and its structure is: clamp 1 is flexible strip shape, can doubling closed; On the closing face of clamp, have the closed latch 2 that can misplace mutually, there is cylindric draw-in groove 4 end, and the other end is the card hammer 3 that enters cylindric draw-in groove, whole formation obliteration folder 5; Described obliteration folder, its integral body is made by degradation material.

Described cylindric draw-in groove 4, its structure is: have and can insert the top layer cylinder of card hammer 3 and the inner layer cylinder that is greater than top layer cylinder of ining succession forms.

Described card hammer 3, is elastic shape, connects hammer be comprised of neck, and neck length is slightly larger than top layer cylinder thickness, hammers the inwall that is stuck in top layer cylinder for spherical into shape.

The latch 2 that described dislocation is closed, consists of the convex tooth of cuboid and onesize concavity tooth, and the angle of convex tooth is circular-arc, and the edge, middle part of cuboid is slightly protruding, and described slightly protruding to be convex tooth form tight fit with concavity tooth is closed mutually.
