Description

Muscle fiber sampling device for dermatology department

Technical Field

The utility model relates to the field of medical equipment, a muscular fiber sampling device for dermatology specifically says so, its mainly applicable muscular fiber's sampling.

Background

In the prior art, in the muscle sampling process, after local anesthesia, skin and muscle membranes are cut open, muscles are separated by using a curved forceps, the muscles are picked out, and the muscles are clamped by using a straight forceps or a curved forceps and cut off by using a scalpel for inspection. The muscle is elastic, the bent forceps are difficult to pick out the muscle, frequently slip off and need to be repeatedly operated, the muscle can be damaged, the skin incision is enlarged if necessary, and the scar enlargement after the skin healing is more easily caused; the muscle may be cut back to its original position and the operation is repeated. These conditions can also lead to artificial muscle damage that misleads the results of pathological examinations. The special muscle fiber sampling device has the problems of complex structure, high manufacturing cost, inconvenient use and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a skin branch of academic or vocational study is with muscle fibre sampling device, fundamentally has solved above-mentioned problem, and it has advantages such as simple structure is compact, convenient to use is swift.

In order to achieve the above purpose, the utility model provides a following technical scheme: this flesh fibre sampling device for dermatology includes first holder of mutual articulated and second holder, and each holder includes handle, the joint portion of mutually supporting, hook portion, and its technical essential is: a push rod component is limited between the two clamping pieces; the push rod assembly comprises a limiting part rotatably arranged on the first clamping part, a push rod arranged in the limiting part, a spring arranged between the limiting part and the push rod, an arc pressing sheet arranged at the front end of the push rod and matched with the hook part, and a pair of connecting rods hinged at the rear end of the push rod, wherein the connecting rods are hinged on the first clamping part and the second clamping part respectively.

The beneficial effects of the utility model are that on the whole technical scheme, the arc preforming that is located the front end can cooperate the hook portion of each holder front end to press from both sides the muscle fibre both ends tightly to realize fixing a position effectively through the mutual joint of joint portion between the holder, effectively avoided the problem that the sample drops after the sample.

In the local structure, the limiting part is rotatably assembled on the second clamping part, the push rod can be in sliding fit in the limiting part, the spring can be compressed in the sliding process, the push rod is always under the elastic action towards the front part, and the defect that the push rod cannot return when being pulled to be over-positioned is avoided. The radian of the arc-shaped pressing sheet at the front part of the push rod is completely matched with the inner arc of the hook part, and the clamping parts between the clamping pieces can be clamped with each other, so that the stability and reliability of the sampling process are ensured.

Detailed Description

The following describes the present invention in detail with reference to fig. 1 to 2 by way of specific embodiments. This flesh fibre sampling device for dermatology department includes first holder 1 and second holder 2 of mutual articulated (first holder 1 bottom be equipped with second holder 2 through-hole 24 matched with protruding structure), first, second holder 1, 2 respectively including first, second handle 12, 22, mutually supporting first, second joint portion 11, 21, first, second hook portion 15, 25. A push rod component 3 is limited between the two clamping pieces 1 and 2. The push rod assembly 3 comprises a limiting member 34 rotatably arranged on the groove 14 of the first clamping member 1 through a protrusion 341, a push rod 32 arranged in the limiting member 34, a spring 33 arranged between a limiting groove 342 of the limiting member 34 and a push rod groove 321 of the push rod 32, an arc-shaped pressing sheet 31 arranged at the front end of the push rod 32 and matched with the hook portion, and a pair of connecting rods 36 hinged at the rear end of the push rod 32 through pins 35, wherein the connecting rods 36 are respectively hinged on the first pin 13 of the first clamping member 1 and the second pin 23 of the second clamping member 2.

Before sampling, the left and right clamping pieces are folded towards the center line, the push rod 32 is pulled by the connecting rod to move towards the rear part (the side of the arc-shaped pressing piece 31 is the front part, and the side of the handle of the clamping part is the rear part), and the arc-shaped pressing piece 31 is separated from the hook part. After the hook part hooks muscle fibers, the left clamping piece and the right clamping piece are opened towards the direction far away from the midline, the push rod 32 moves forwards under the action of the connecting rod 36, the spring 33 is compressed in the annular groove of the corresponding part, the arc-shaped pressing piece 31 is matched with the hook part, a muscle fiber sample is firmly pressed between the arc-shaped pressing piece and the hook part, and a scalpel cuts the muscle. Has the advantages of small operation opening, quick muscle hooking and small muscle damage. There is currently no similar instrument.
