Abstract

The invention discloses a preparation method of medical suture thread by drawing nutria tail tendon. The method for drawing nutria tail tendon has complex technology, has a great damaging influence on tendon and wastes time and labor. The preparation method simplifies the technology for drawing nutria tail tendon. The autologous biological enzyme of the nutria tail is matched with outside thermal insulation to accelerate the autologous enzyme to be activated; the autolysis accelerating action of the autologous enzyme system is activated to accelerate biochemical reaction in the tail; and muscle and tendon are automatically separated, which is convenient for manually or mechanically extracting tail tendon. The preparation method is an advanced method which is convenient and quick, guarantees quality, lowers cost and improves the use ratio of the tail tendon.

Description

Extract coypu tail muscle and make the preparation method of suture

One, technical field

It is the preparation method that castor otter tail muscle is made suture that coypu is extracted in the invention, coypu has another name called a kind of rodent that the castor otter is a mammal, based on herbvore, hind leg has web to live in water, the adult about 4-8 kilogram of coypu body weight, tail is about the 25-40 centimetre, muscle in the tail is that collagen protein constitutes, the 50-80 root is arranged approximately, varying length, thickness does not wait, and this tail muscle extracts the raw material that is widely used in article of everyday use such as suture face-lifting, beauty treatment, cosmetic as biological product.

Two, background technology

Mammal tendon tissue stitching thread [No. the 3650635th, state's pencil tool (standard) word 2002], the creative method of producing of nerve fiber absorbable suture has been declared patent, patent No. ZL200610079127.2, No. the 418423rd, certificate number (above two kinds of products belong to identical product), more than two products be widely used in clinical, because this product is translucent white is that collagen protein constitutes, therefore be difficult to catch other color, thereby during the when injected organism tissue beyond the skin suture, this product is difficult to distinguish when injected organism tissue or stitching thread once sticking blood, bring inconvenience to the operator, according to existing market also do not occur utilizing stitching thread that castor otter tail muscle produces except that grey thread and the listing of colo(u)r streak kind, the invention and created name dyeing preparation method of surgical sutures produced by tail tendons of nutria has been declared number of patent application 201010244435.2.

Three, innovation and creation content

The preparation method that coypu tail muscle is made suture is extracted in the invention, by following measures reach coypu slaughtered after, the skin of peelling off on the tail extracts the tail muscle then.

Four, specific embodiments

1, embodiment one

(1) after being slaughtered, coypu peels off skin on the tail, cut off the tail pond of going into to disinfect with salt solution from root of the tail, the saline salinity is 10% in the sterilization pool, till tail is put into the back and is flooded tail with saline, brine temp is remained on 35 ℃, constant temperature 4 hours, at this moment the spontaneous lyase in the tail begins to play a role, occur the self-dissolving decomposing phenomenon in tail, promptly the tail muscle in the tail and the muscle of tail play centrifugation.

(2) insulation utilizes the saline in the pond after 4 hours, cleans the foreign material that adhering on the tail and removes blood stains, with leave away moisture on the tail of centrifuge, imports sterilizing room into then.

2, embodiment two

(1) will put into the tail of sterilizing room, be fixed on the cramp platform, the cramp function Rotate 180 degree on the cramp platform, be divided into equal 4-6 section from root of the tail to the tail point be the 4-6 circle with being fixed on tail on the cramp machine, is convenient to take out the tail muscle

(2) the metal cramp hook on the cramp machine is below extracted out the tail muscle from first section distribution that is root of the tail is inserted into the tail muscle that just can see from the surface, cut short to put into from the muscle root and contain the muscle dish, press the aforesaid operations method, operating up to the 6th circle successively from first lap to the second circle is that the tail point is all extracted muscle out.

Three, embodiment three

(1) with the tail muscle that extracts in sterilizing room, remove the when injected organism tissue that remains on the muscle again with the clean blood stains of aseptic clear water, put into aseptic hurricane drier about 2 hours of 35 ℃ of following air-dry times of temperature.

(2) the tail muscle after air-dry is that edematus is white, and to select muscle to divide fineness degree on the muscle be that diameter is 0.2 millimeter-1 millimeter selecting, and length is 15 centimeters-20 centimeters, more than 30 centimeters, classification, divides grade packagedly, and suture is a finished product.

Preparation method's advantage of the invention medical suture thread by drawing nutria tail tendon, he has simplified the complicated technology that extracts coypu tail muscle, this method is easy, the saving of labor, the saving cost saves time, minimizing is to the damage of muscle, guaranteed quality, be the best way that now extracts at present coypu tail muscle, enlarged the use to coypu tail muscle.

Claims

1. extract coypu tail muscle and make the preparation method of suture, peel off the skin on the tail after coypu slaughtered, cut off the tail pond of going into to disinfect with salt solution from root of the tail, the saline salinity is 5%-10% in the sterilization pool, and till tail was put into the back and flooded tail with saline, insulation was 25 ℃-35 ℃ in the brine pit, constant temperature 4 hours, at this moment the spontaneous lyase in the tail begins to play a role, and occurs the self-dissolving decomposing phenomenon in tail, and promptly the tail muscle in the tail and the muscle of tail play centrifugation.

2. be incubated tail after 4 hours and utilize saline in the pond again, clean the foreign material of adhering on the tail and remove blood stains, then with leave away moisture on the tail of centrifuge, import sterilizing room at aseptic in-house operation, being divided into the 4-6 section by root of the tail to the tail point is the 4-6 circle, because of tail is a cast, operation is extracted the tail muscle from first section root of the tail out successively to the tail point.

3. the metal cramp hook on the cramp machine is below extracted out the tail muscle from first section distribution that is root of the tail is inserted into the tail muscle that just can see from the surface, press the aforesaid operations method, operating up to the 6th circle successively from first lap to the second circle is that the tail point is all extracted muscle out.

4. will take out tail muscle edulcoration in sterilized water remove the blood stains on the muscle and remain in when injected organism tissue above the muscle, in 30 ℃-35 ℃ hurricane drier aseptic air-dry 2 hours, tail muscle after air-dry be translucent, color is white, by diameter is 0.2 millimeter to 1 millimeter, length is 15 centimeters, 20 centimeters, classification more than 30 centimeters, dividing grade packaged suture, is finished product.
