Abstract

The invention relates to a bio paracentesis needle and a method for manufacturing the same. The bio paracentesis needle comprises a tube-shaped body having a hollow portion through which a suture is inserted, and an insertion portion formed at an end of the body to cut skin and insert the body. The insertion portion includes a first inclined edge having a diagonal surface inclined downward in a direction from a first end of the body to the hollow portion, a second inclined edge having a diagonal surface inclined upward from a second end of the body to the first inclined edge, the second end being positioned opposite the first end, and a third inclined edge has a diagonal surface inclined downward in a direction from an end of the first inclined edge to the second inclined edge. Therefore, when inserted into skin wrinkles, the needle can be inserted thinly along the wrinkles.

Description

technical field [0001] The present invention relates to a biological puncture needle which can be thinly inserted along a skin wrinkle when being inserted into a skin wrinkle by forming an end portion of the needle like a blade, and a manufacturing method thereof. Background technique [0002] The use of puncture needles is very extensive, and it is widely used in various purposes and uses such as extracting cerebrospinal fluid or injecting drugs. In particular, in plastic surgery, the needle inserts sutures used in plastic surgery into the skin, and it injects the sutures into the skin in order to smooth out wrinkles on the face. [0003] In the biological puncture needle disclosed in Korean Laid-Open Patent Publication No. 2000-0068025 and its manufacturing method, compression processing is performed on the front end of the hollow cylindrical part of the needle blank to form a needle from the hollow cylindrical part to the front end. The hollow conical portion, in turn, h...
