Abstract
A hemangioma clamp with a film includes a metal clamp and a coating film(3). The metal clamp includes a first clamp rod(5) and a second clamp rod(6) across overlapping with each other by tails through an elastic device(7). A first clamp arm(1) and a second clamp arm(2) are disposed respectively at the terminals of a semi collar(8) of the first clamp rod(5) and a semi collar(9) of the second clamp rod(6). The two ends of the coating film(3) are connected respectively with the first clamp arm(1) and the second clamp arm(2) to form a film casing. The hemangioma clamp with a film can enwrap the peripheral of the clamped blood vessel to prevent the tumor capsule broken and has rectification and strengthening functions, so the treatment effect is good and it is safe to use the hemangioma clamp.
Description
Technical field
This utility model relates to a kind of blood vessel tumor clip, and it is to be used for the treatment of angiomatous device, belongs to the medical apparatus and instruments of implant into body.
Background technology
Hemangioma especially aneurysm is one of common angiopathy, angiomatous Therapeutic Method has multiple, hemangioma for some form, with blood vessel tumor clip that the tumor capsule is dead from root (orientation parallel with blood vessel wall) folder, the tumor capsule is closed, and is a kind of easy Therapeutic Method, is specially adapted to those and is difficult to the naked position, this a kind of method for a long time in clinical practice, short run effect is good.But because when forming hemangioma, it is also drawn thin in axial vertical opposite side blood vessel wall, close the yet further attenuation and form new tumor capsule of tumor capsule one rear flank opposite side, therapeutic effect is not good enough; For the fusiformis hemangioma, can't treat especially with common blood vessel tumor clip.
Summary of the invention
The purpose of this utility model provides a kind of novel blood vessel tumor clip, this vascular clamp has tough and tensile wrap film, it can wrap up the blood vessel periphery at folded position, to preventing that the further tumor in this position from becoming and preventing that the tumor capsule from breaking remarkable effect is arranged, and can improve therapeutic effect greatly.
Technical solution of the present utility model is: the blood vessel tumor clip of band film, it is made up of metal clip and wrap film, wherein metal clip comprises first clamping bar and second clamping bar of afterbody by the continuous mutual cross-lapping of elastic device, end at half collar on first clamping bar and half collar on second clamping bar is provided with first jig arm and second jig arm separately, the two ends of wrap film are connected on described first jig arm and second jig arm, form Membrane cover.
Described wrap film is that the material of these high polymers is to human body nonhazardous effect by synthetic material politef, terylene, polyurethane, polypropylene, polysiloxanes, polyamide or prepared film of polyester urethane or mesh grid, and structure is tough and tensile, wraps up effective.
Described wrap film or by the diaphragm of pig, cattle or sheep, fatty nethike embrane, pericardium or goldbeater's skin through crosslinked fixing and go antigen to handle after formed film, such raw material is drawn materials easily, cost is lower, helps applying.
Animal tissue easily is degraded by microorganisms or decomposes, and uses crosslinked with it its stability that fixedly improves of aldehydes (formaldehyde, glutaraldehyde etc.) traditionally; But aldehydes can discharge deleterious aldehyde by aldolisation and protein cross during its cross-linking products degraded, and making has extended residual toxicity with the fixed goods of aldehyde.When using the no-aldehyde fixative, as epoxide, two acid diamides, vulcabond or carbodiimides, just there is not this shortcoming, with the epoxide is example, because epoxide comes the cross-linked proteins molecule by ring-opening reaction, can not form epoxide more easily after the open loop, its catabolite is can be by the polyhydric alcohol of organism metabolism, the residual toxicity of no aldehydes, the stability of the animal tissue after the processing also than with original with aldehydes fixed height; According to modern immunology theory, the antigenicity of animal tissue mainly is to cause that by the active group of some specific position in the protein molecule and special conformation these active groups mainly contain-OH ,-NH
2-SH etc., and special conformation normally since some of protein molecule coiled strand hold different hydrogen bond and cause, when handling animal membrane and organize, easily combine with these groups with one or more with the active reagent (as anhydride, acyl chlorides, amide, epoxide etc.) that these groups react, it is closed, thereby removes its antigen, simultaneously, also use strong hydrogen bonding reagent (as guanidine compound), displacement causes the hydrogen bond of special conformation, changes its conformation, further eliminates its antigenicity.The animal membrane tissue is after crosslinked fixing, be difficult for being degraded by microorganisms or decomposing, the life-time service non-residual toxicity, by the active group in the closed protein matter molecule and its conformation of change, effectively remove its immunizing antigen again, there is not chronic immune rejection in formed biomembrane, has excellent biological compatibility, such blood vessel tumor clip can wrap up the blood vessel periphery at folded position in use, plays good therapeutic effect.
As a kind of prioritization scheme, being provided with coupling on the surface of the wrap film of using the tough and tensile tissue of animal to make has the specific polypeptide or the formed active surface layer of glycosaminoglycan active component that can adhere to somatomedin.One of described specific polypeptide is formed by 16 lysines (K16), glycine (G), arginine (R), aspartic acid (D), serine (S), proline (P) and cysteine (C) polycondensation, and described glycosaminoglycans is hyaluronic acid, chondroitin sulfate, dermatan sulfate, heparin, Heparan sulfate or keratan sulfate.The cells of vascular wall that these active components help being wrapped up is grown into and is merged with vascular wall tissue, plays biological the reinforcing and protective effect.
Described metal clip is made by medical stainless steel or titanium alloy.
The length of described wrap film equates with corresponding girth by the formed collar of described half collar, has guaranteed to contact with the tight of parcel blood vessel.
The utility model has the advantages that: the blood vessel tumor clip of this band film can wrap up the blood vessel periphery at folded position, prevents that the tumor capsule from breaking, and plays and corrects and the reinforcement protection effect, and therapeutic effect is good, and is safe and reliable.
