Abstract
The invention discloses a method for manufacturing biological film trochlea and the biological film trochlea, and belongs to the technical field of medical treatment surgical operation materials, in particular to the technical field of finger flexor tendon trochlea reconstruction operations. The method for manufacturing the biological film trochlea comprises the following steps that a medical biological film with the size being 80 mm*50 mm*0.02 mm is folded in half along the wide axis into the medical biological film with the size being 80 mm*25 mm*0.04 mm, the folded planes are bonded through medical biogel, folding in half is carried out twice along the long axis, bonding is carried out through the medical biogel, then the biological film with the size being 20 mm*25 m*0.16 mm is formed through folding and is folded towards the same direction by 3 mm along the two 25-milimeter edges, the folded biological film is folded towards the reverse directions into a semiarc, then a biological film sheathing canal with the thickness being 0.16 mm is manufactured, the reflexed parts of the two sides of the sheathing canal are sheathing canal bases, and the sheathing canal bases are connected with the sheathing canal. The invention further provides the biological film trochlea manufactured through the method. According to the technical scheme, the effect of the sheathing canal trochlea can be brought into play, the vice damage of the operation is reduced, and the biological film trochlea has the advantages of being simple, effective, safe, reliable and the like.
Description
Technical field
The present invention relates to medical surgery surgical material technical field, relate in particular to a kind of manufacture method and this biomembrane coaster of the biomembrane coaster for flexor tendon stndon sheath coaster repair process.
Background technology
The tackle system that refers to flexor tendon stndon sheath is the fibrous sheath of tendon thickens formed a series of different-thickness, width and form dense connective tissue at different parts, has constraint flexor tendon, gives full play to the effect of the function of counting on one's fingers.At present, the count on one's fingers method for reconstructing of coaster comprises free palmaris longus tendon winding method, flexor superficialis tendon one side tendon bundle reconstruction method, retinacula tendinum musculorum extensorum reconstruction method, fascia lata reconstruction method, terylene artificial material reconstruction method and woven nylon material reconstruction method etc.Four kinds of methods are wherein more conventional, and effect is also more definite, but need to transplant tendon or fascia, and sometimes even needing the partial function of sacrificing for district is cost, and some cases effect is still not good; Two kinds of methods below adopt artificial material and nylon material, do not need for district, but because tissue reaction is larger, often cause the generation of adhesion of tendon, the effect of impact operation.
Summary of the invention
Rebuild coaster existence damage for district owing to transplanting tendon, the shortcomings such as artificial material poor effect, in order to solve the problems of the technologies described above, the object of this invention is to provide a kind of manufacture method and this biomembrane coaster of biomembrane coaster, the biomembrane coaster that the method is made, can bring into play the effect of sheath pipe coaster, reduce again the pair damage of operation, and there is simple effective and safe and reliable feature.
The object of the invention is to be achieved through the following technical solutions:
The medical biomembrane that one is 80mm × 50mm × 0.02mm by size is first folded in half into 80mm × 25mm × 0.04mm along wide axle, by fold plane medical bio glue, again along major axis doubling 2 times, and paste with biogum, be folded in half into like this 20mm × 25mm × 0.16mm size biomembrane, along the both sides of 25mm respectively to a direction flanging 3mm, be converted into round about again semiarc shape, the biomembrane coaster that so just to have made thickness be 0.16mm, this biomembrane coaster comprises the sheath pipe of semiarc shape, the invayination of sheath pipe both sides is divided into sheath pipe base, sheath pipe base is connected with sheath pipe.
In operation by sheath pipe box on tendon, two wing bases and tendon surrounding tissue are sewed up, and so just make a tendon coaster.
The present invention also protects the concrete structure of the biomembrane coaster of making by said method itself.
By the technical scheme of the invention described above, the medical biomembrane that the present invention adopts is that one is made up through chemical treatment of sheep casing, the biological semipermeable membrane of thick about 0.02mm, hot strength > 5Mpa, main by the physical isolation effect of film, by the organizational interface of postoperative easy adhesion separately, reach the effect of Film with Preventing Adhesion.It has following characteristics: good biocompatibility, to organizing without pessimal stimulation; Absorbability is good, in vivo degradable absorption; Quality softness, adhesiveness is good, easy to use.Have excellent permeability, the tissue on film both sides can carry out the exchange of nutrient substance, and its effective biological iris action can reach more than 1 month, can stimulate body to form " false sheath ", provides smooth tissue bed for tendon slides; Meanwhile, early stage in tendon repair, between film and tendon, can leave certain interval, in blood, the tissue fluid that surrounding tissue is oozed out riddles, can, by tendon anastomosis mouth parcel, also easy adhesion position and tendon can be isolated to the effect of playing Film with Preventing Adhesion.Can not only be for healing process of tendons provides abundant nutrition, promote endogenous healing, can also effectively block the exogenous healing of tendon, neither affect healing process of tendons thereby reach, can prevent that again adhesion from occurring.Our research is found, after placement biomembrane, after 3 months, in operation, finds that paratenon is smooth, forms a kind of sliding channel of similar sheath pipe.Biomembrane coaster of the present invention has very large advantage and application prospect in prevention adhesion of tendon.
