Abstract
The utility model discloses a biological membrane trochlea, and belongs to the technical field of medical surgical operation materials, particularly to the technical field of finger flexor tendon trochlea rebuilding techniques. The biological membrane trochlea comprises a medical biological membrane sheath with the thickness of 0.16mm and sheath bases connected with the medical biological membrane sheath; the sheath is semi-arc shaped; the sheath bases are arranged on the two sides of the end part of the semi-arc shaped sheath; the medical biological membrane sheath and the sheath bases are formed by eight layers of medical biological membranes with thickness of 0.02 mm, which are adhered to each other with medical biological glue. The technical scheme of the biological membrane trochlea not only can play the role of a sheath trochlea, but also reduces secondary damages caused by an operation, and has the characteristics of simplicity, effectiveness, safety, reliability and the like.
Description
Technical field
This utility model relates to medical surgery surgical material technical field, relates in particular to a kind of biomembrane coaster for flexor tendon stndon sheath coaster repair process.
Background technology
The tackle system that refers to the flexor tendon stndon sheath is the fibrous sheath of tendon thickens formed a series of different-thickness, width and form at different parts dense connective tissue, has the 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.Wherein four of the front kinds of methods are more commonly used, and effect is also more definite, but need to transplant tendon or fascia, sometimes in addition the partial function that needs to sacrifice for the district be cost, the some cases effect is still not good; Two kinds of methods of back adopt artificial material and nylon material, do not need for the district, but because tissue reaction is larger, often cause the generation of adhesion of tendon, the effect of impact operation.
The utility model content
Rebuild coaster existence damage for the 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 purpose of this utility model provides a kind of biomembrane coaster, this biomembrane coaster, can bring into play the effect of sheath pipe coaster, reduce again the pair damage of operation, and have simple effective and safe and reliable characteristics.
The purpose of this utility model is achieved through the following technical solutions:
A kind of biomembrane coaster comprises that thickness is the medical biomembrane sheath pipe of 0.16mm and the sheath pipe base that links to each other with the sheath pipe; Described sheath pipe is semiarc shape, and sheath pipe base is located at the both sides of semiarc shape sheath tube end; Described medical biomembrane sheath pipe and sheath pipe base are that 8 layers of medical biomembrane of 0.02mm consist of by thickness, use the medical bio glue between each layer biomembrane.
In operation with the sheath pipe box on tendon, two wing bases and tendon surrounding tissue are sewed up, and so just make a tendon coaster.
By above-mentioned the technical solution of the utility model, the medical biomembrane that this utility model adopts is a kind ofly to be made through chemical treatment by sheep casing, the biological semipermeable membrane of thick approximately 0.02mm, hot strength＞5Mpa, main physical isolation effect by film, the organizational interface of the easy adhesion of postoperative is separated, reach the effect of Film with Preventing Adhesion.It has following characteristics: good biocompatibility, to organizing without bad stimulation; Absorbability is good, in vivo degradable absorption; Quality is soft, and adhesiveness is good, and is 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; Simultaneously, early stage in tendon repair, can leave certain interval between film and tendon, in the blood that surrounding tissue is oozed out, tissue fluid riddle, can with tendon anastomosis mouth parcel, also easy adhesion position and tendon can be isolated the effect of playing Film with Preventing Adhesion.Can not only promote the endogenous healing for healing process of tendons provides abundant nutrition, can also effectively block the exogenous healing of tendon, neither affect healing process of tendons thereby reach, can prevent that again adhesion from occuring.Our research is found, finds in the operation after 3 months behind the placement biomembrane that paratenon is smooth, forms a kind of sliding channel of similar sheath pipe.Biomembrane coaster of the present utility model has very large advantage and application prospect in the prevention adhesion of tendon.
Description of drawings
Fig. 1 is biomembrane coaster perspective view of the present utility model;
Fig. 2 is the schematic diagram that biomembrane coaster of the present utility model is used for the prosthesis of flexor digitorum muscle of hand tendon.
The below is described in further detail accompanying drawing:
Fig. 1 is the perspective view of biomembrane coaster, and this biomembrane coaster comprises the sheath pipe 11 and the sheath pipe base 12 that is positioned at sheath pipe 11 both ends with the radian shape.
Fig. 2 is the concrete application of biomembrane coaster in the operation of flexor digitorum muscle of hand tendon.Wherein, finger 31, flexor tendon 32, biomembrane coaster 1, the sheath pipe 11 of biomembrane coaster, the sheath pipe base 12 of biomembrane coaster, the suture 21 of connection biomembrane coaster and muscle.
The above; it only is the better specific embodiment of this utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
