Abstract
The present invention discloses a method for preparing an adhesion preventing biomembrane for tendons and ligaments, which contains spongy medical collagen material with pores, has the advantages of stable structure and favorable biocompatibility and can be degraded and absorbed, and an application of the adhesion preventing biomembrane. Tissues of beef tendons are used as base material, impurities are removed, and then, the tissues are washed, treated by acid, alkali and enzymes and crosslinked by chondroitin sulfate. I-shaped collagen with protein purity higher than 95% is lyophilized to obtain a degradable biomembrane with the pore space of 80 to 200 micrometers and the thickness of 0.05 to 1.5 millimeters. Clean sewn tendons or ligaments are covered by adopting a packaging and winding method in operation. Patients can make proper early movement after operation. A peripheral tissue forms a neomembrane on a collagen membrane to prevent the adhesion of the peripheral tissue and a tendon, so that the purpose of preventing the adhesion of tendons and ligaments is achieved.
Description
Affiliated technical field:
The present invention relates to medical biotechnology material technology field, be specifically related to a kind of biomembranous preparation and application that tendon, ligament injury and postoperative is prevented adhesion.
Background technology:
Continuous development along with medical science development of technology and medical material, obtained significant development at medical field based on the product of collagen protein in recent years, as Chinese patent, the patent No. is 021212779, patent name is that medicinal collagen material and manufacturing process thereof disclose a kind of medicinal collagen material, with the cattle tendon tissue is base material, through remove impurity, clean, acid, alkali, enzyme is handled, the chondroitin sulfate agent is crosslinked, operation such as lyophilization and ethylene oxide sterilizing is made has hole, spongy medicinal collagen material has Stability Analysis of Structures, good biocompatibility, the characteristics that degradable absorbs.At present, be used for cerebral dura mater, spinal dural reparation and anti clinically.Use the expansion of this material and technology and extend to the important topic that the other treatment field is a biomedical sector.
At present; solve and recover the tendon of Orthopeadic Surgery hand because of tendon and ligament injury postoperative; the ligament adhesion is the difficult problem that global urgent need solves; influence the normal activity in joint because of the formation of cicatrix causes the adhesion of tendon and ligament behind the bone surgery, the no stndon sheath tendon injury more than 90% need be carried out for the first time the operation of loosening of selecting a time of the secondary of postoperative.At present, the dexamethasone hormone of clinical use and the therapeutic effect of biological fibrin glue and other materials are not obvious, can not effectively prevent the formation of adhesion.
Summary of the invention:
The purpose of this invention is to provide a kind of have hole, spongy medicinal collagen material, have the preparation method and the application that are used for tendon, ligament anti blocking biomembrane of Stability Analysis of Structures, good biocompatibility, degradable absorption.
In order to achieve the above object, the present invention adopts following technical scheme: by the cattle tendon is base material, through peracid, alkali, enzyme handle and chondroitin sulfate crosslinked, make after lyophilization, the sterilization purity of protein more than 95%, hole is the spongy type i collagen protein biology film of 80～200 μ m, thickness 0.05～1.5mm.When tendon that carries out hand or other positions and operation on ligament after it is sewed up, with the direct tubular ring of anti blocking biomembrane around covering on the impaired tendon or ligament, the extraneous tissue of blocking-up directly contacts with it, tendon outside organization produces pseudomembrane because of the special construction of collagem membrane makes it, stops growing into of outside cell and forms adhesion.
Its purity of protein height of type i collagen protein material biomembrane provided by the present invention, molecular structure stabilized, there are specific pore structure and tissue that good biocompatibility and controllable degraded and absorbed are arranged, be used for preventing tendon and ligament adhesion behind the bone surgery, provide curative effect reliable, easy to use, be with a wide range of applications.
The specific embodiment:
Provided by the present invention is that the biomembrane that prevents tendon and ligament adhesion of material proves that in zoopery preventing adhesiving effect is remarkable with type i collagen albumen.Specific implementation method is: by the cattle tendon is base material, through peracid, alkali, enzyme handle and chondroitin sulfate crosslinked, make after lyophilization, the sterilization purity of protein more than 95%, hole is that the spongy type i collagen albumen anti blocking biomembrane of 146 μ m, thickness 0.2mm is standby; Extremity tendon that animal is damaged and ligament undergo surgery sew up after, with the direct tubular ring of the anti blocking biomembrane of 20 * 30mm around covering on the impaired tendon or ligament; Crust is sewed up and planter cast then.The extremity of 2 week of operation back passive activity damage are removed Gypsum Fibrosum all around, continue the extremity of passive activity damage.12 weeks were observed sacrifice of animal, anti blocking biomembrane has played the extraneous tissue of blocking-up and its effect that directly contacts, tendon and ligament outside organization produce pseudomembrane because of the special construction of collagem membrane makes it, stop growing into of outside cell and form adhesion, and preventing adhesiving effect is remarkable.
Claims (3)
1. the preparation method of a tendon, ligament anti blocking biomembrane is a base material by the cattle tendon, and through peracid, alkali treatment, Protease Treatment and chondroitin sulfate are crosslinked, and making hole behind the dry sterilization is 146 μ m, and thickness is the spongy collagen protein biomembrane of 0.2mm.
2. a kind of tendon, the ligament anti blocking biomembrane that make of the described method of claim 1, it is characterized in that: the biomembranous hole of spongy collagen protein is 146 μ m, and thickness is 0.2mm.
