Drawings
Fig. 1 is a schematic view of the main structure of the present invention;
FIG. 2 is a schematic view of the expanded structure of the main body of the present invention;
in the figure: 1. the device comprises a main body, an upper extraction part, a 3 upper extraction knife edge, a 4 lower extraction knife edge, a 5 lower extraction part, a 6 compression spring, a 7 compression spring support rod, a 8 bending transition part, a 9 compression rod.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the fascia extraction device comprises a clip-shaped main body 1, wherein the main body 1 is of an integral structure and is divided into an upper part and a lower part by a middle bending transition part 8;
the front end of the upper part of the main body 1 is provided with an upper extraction part 2 provided with an upper extraction knife edge 3, and the front end of the lower part of the main body 1 is provided with a lower extraction part 5 provided with a lower extraction knife edge 4;
the upper extraction knife edge 3 of the upper extraction part 2 is a circular sharp bulge, the lower extraction part 5 is a hollow conical groove structure, and the edge of the upper part of the lower extraction part is provided with a sharp bulge to form a lower extraction knife edge 4.
Further, the diameter of the lower extraction knife edge 4 is 15mm, and the diameter of the upper extraction knife edge 3 is slightly smaller than that of the lower extraction knife edge 4. And the tooth surfaces of the cutter heads of the upper and lower knife edges are staggered, so that the fascia is extracted.
Further, the groove depth of the lower extraction part 5 is 5 mm. Meets the requirement of fascia extraction in the actual operation process.
Furthermore, a pressure spring 6 for adjusting the opening degree of the main body 1 is arranged between the upper part and the lower part of the main body 1 and close to the bending transition part 8. The bending transition part 8 has certain toughness, and the toughness of the opening degree of the main body 1 is further enhanced through the action of the compression spring 6, so that the strength and the operability of the extraction device are improved.
Further, the pressure spring 6 is fixedly connected with two side walls of the main body 1 through pressure rods 9 at the front ends of two sides. The connection between the compression spring 6 and the main body 1 and the adjustment of the opening and closing degree are realized through the compression rod 9.
Further, the compression spring 6 is fixedly connected with a bending transition part 8 of the main body 1 through compression spring support rods 7 at the rear ends of the two sides. The fixing effect on the pressure spring 6 is realized.
The use process of the extraction device is as follows:
the device is generally useful in otology where repair of the tympanic membrane is often required, most often with autologous temporalis fascia. The posterior auricular incision is surgically pulled open, and the fascia is incised after exposing the fascia on the surface of the temporal muscle. The fascia extractor can be extended into the fascia after separating the surrounding tissues, and the fascia is cut by mutually occluding the upper extraction incision 3 of the upper extraction part 2 and the lower extraction incision 4 of the lower extraction part 5 by kneading the clamp-shaped main body 1, so that the circular fascia is extracted to repair the tympanic membrane.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
