Abstract
The utility model relates to a multifunctional extracting needle for puncturing, which overcomes the defects of common syringe needles of difficult extraction in the process of puncturing and extracting living-body tissues or adipose tissues. The utility model is composed of 2 to 4 needle tips and a needle core that can be inserted into the needle tips and that can be fixed with the needle tips on a needle tube, and meanwhile, a needle hole is arranged on the needle core near the tip thereof. With the needle, user can use a plurality of needle tips to cut the tissues in a ring shape under the cutting action of a plurality of fixed puncturing points and a plurality of inclined planes between each two needle tips when the needle tips are pushed into the tissues, and then can conveniently extract the living-body tissues or adipose tissues via the negative pressure.
Description
This utility model relates to a kind of medical instruments, specifically is a kind of multi-functional puncture suction needle.
Employed clinically puncture suction needle is common injection needle at present.This syringe needle in use mainly is to rely on the effect of clamp-oning of injection needle to lunge body and liquid tissue.Therefore, when vacuum suction, more seldom extract biological tissue or fatty tissue, make that the positive rate of biopsy puncture is not high enough, or need inject a large amount of packing fluids and puncture suction back and forth repeatedly during suction lipectomy, bring a lot of miseries to patient.
In view of above syringe needle shortcoming in use, proposition of the present utility model is a kind of to have needle tubing, nook closing member, the puncture suction needle of spininess point.
Multi-functional puncture suction needle has needle tubing, can insert the nook closing member in the needle tubing, the 2-4 at needle tubing tip, has pin hole on the nook closing member.On the needle tubing handle, have the nook closing member socket, and on nook closing member the corresponding nook closing member plug that is provided with.
The multi-functional puncture suction needle structure chart of Fig. 1.
The needle tubing tip (1) of needle tubing (2) is 2 tips, has square nook closing member socket (7) on its handle (3).Nook closing member (4) can be inserted in the needle tubing (2), is locating to have pin hole (6) near its tip (5), contacts with needle core handle (9) in nook closing member (4) upper end and is provided with the nook closing member plug (8) that matches with nook closing member socket (7).The length of nook closing member (4) is identical with the length of needle tubing (2).This pin in use is that two fixedly point of entrance and changed the effect of clamp-oning of common single needle point entry needle are arranged when utilizing two needle points to advance in tissue, by the annular incised tissue of the dissection on 2 inclined-planes between needle point.And then utilize negative pressure can be drawn into biological tissue or fatty tissue easily.Utilize pin hole on the nook closing member (4) to introduce suture in addition and can carry out that various subcutaneous suspentions are fixing to wait the stitching of sunkening cord of moving under water, to avoid doing skin incision.
