An object of the utility model is to provide a sunken needle of peeling off of skin tissue to solve among the prior art problem of skin tissue and deep manadesma tissue adhesion, concrete technical scheme as follows:

a skin tissue concave stripping needle comprises a needle handle and an arc-shaped stripping cutter body; the stripping cutter body is arranged at one end of the needle handle; the thickness of the knife edge of the peeling knife body is gradually increased to the knife back; the lower blade surface of the peeling knife body is parallel to the peeling direction of the skin tissue.

Preferably, the inner arc degree of the arc-shaped stripping cutter body is one third of a circle.

Above technical scheme is preferred, the knife face of the peeling knife body is the arcwall face.

In the preferable technical scheme, the included angle theta between the needle handle and the lower cutter face of the stripping cutter body is 10-30 degrees.

Preferably, the included angle θ is 20 °.

Preferably, the needle handle is cylindrical.

According to the preferable technical scheme, one end of the needle handle close to the peeling cutter body is provided with length scales.

Use the technical scheme of the utility model, following beneficial effect has:

(1) The utility model relates to a skin tissue sunken peeling needle, which comprises a needle handle and an arc-shaped peeling cutter body; the utility model has the advantages that the stripping cutter body is arc-shaped, which is convenient for stripping skin tissues, especially for separating ligaments, and the cutting edge of the stripping cutter body is gradually thickened to the back of the cutter, so that the stripping cutter body is in a structure with a concave middle part, a thin inner part and a thick outer part, which can reduce the resistance when the stripping cutter body is pushed (namely stripping), and can effectively strip; the lower blade surface of the peeling knife body is parallel to the peeling direction of the skin tissue, the stable level of the peeling knife body when being pushed can be ensured, the point is important to the micro-wound, namely, the utility model discloses a peeling needle is high in peeling efficiency and strong in stability.

(2) The utility model discloses the inner arc degree of curved cutter body that peels off is the third circle, both can reduce the injury to subcutaneous tissue like this, can impel operation effect and speed again.

(3) The utility model discloses the last knife face of peeling off the cutter body is the arcwall face, and the form of arc bodiness is adopted to cutting edge to the back of a knife blade promptly, the cutting of being convenient for.

(4) The included angle theta between the needle handle and the lower knife face of the stripping knife body is 10-30 degrees, which is convenient for ensuring the accuracy and stability when an operator holds the needle handle to strip; the utility model discloses further preferred contained angle theta is 20, can further guarantee the convenience and the stability of operation.

(5) The needle handle of the utility model is cylindrical, which is convenient for hand-holding comfort; the length scale of the needle handle is convenient for realizing accurate stripping.
