Abstract

The utility model discloses a novel bone and soft tissue puncture biopsy needle, it includes puncture needle pistil and puncture sleeve, and wherein the puncture sleeve comprises hollow inlayer and hollow skin, and hollow inlayer end is provided with sharp sawtooth, but hollow outer end is provided with sharp elasticity closed elasticity zigzag blade. The utility model discloses a puncture needle pistil, puncture telescopic hollow inside, outside combine, can accurately take out required tissue, but through hollow outer elasticity zigzag blade of closing, can be fast convenient cut off the tissue and send into intraductally, not only solved the difficult problem that the tissue can't take out, protected the vascular nerve on every side simultaneously, improve the factor of safety of operation.

Description

Novel bone and soft tissue puncture biopsy needle

Technical Field

The utility model relates to the field of medical equipment, specifically a novel bone and soft tissue biopsy needle that punctures.

Background

When a lesion occurs in a tissue, the nature and degree of the lesion need to be judged, which is mainly realized by sampling and analyzing the lesion tissue. Sampling of diseased tissue is a necessary process. At present, the puncture biopsy needle for puncture biopsy of bone and soft tissue tumor, particularly bone tumor, is mainly used for hollow drill for vertebroplasty, the material taking of the osteogenic tumor is relatively easy, but the grabbing of the osteogenic tumor is difficult, and the tumor tissue is just in the hollow drill, but no grabbing equipment is provided. Some try to grab the tumor by stretching a small grasping forceps, but the forceps heads are very small and often grab blindly, so that the material taking amount is small, and peripheral vascular nerves are easy to be injured.

Disclosure of Invention

The utility model discloses a novel bone and soft tissue aspiration biopsy needle, through puncture needle pistil and the telescopic cooperation of puncture, not only solved the difficult problem that the tumour can't take out, protected vascular nerve on every side simultaneously, improved the factor of safety of operation.

The utility model discloses technical scheme as follows:

A novel bone and soft tissue puncture biopsy needle comprises a puncture needle core and a puncture sleeve which are nested with each other, wherein the tail end of the puncture needle core is a needle handle, and the front end of the puncture needle core is a needle point; the puncture sleeve consists of a hollow inner layer and a hollow outer layer which are mutually nested, the tail end of the hollow inner layer is provided with a handle, and the front end of the hollow inner layer is provided with uniformly distributed sawteeth; the tail end of the hollow outer layer is provided with a handle which is also used as a baffle, and the front end of the hollow outer layer is provided with a sawtooth-shaped blade which can be elastically closed.

Furthermore, the length of the puncture needle core is 1-2 cm longer than that of the puncture sleeve.

furthermore, the length of the hollow inner layer is 0.5-1 cm longer than that of the hollow outer layer.

Furthermore, the saw teeth of the hollow inner layer and the saw teeth blades of the hollow outer layer are made of stainless steel materials, and the end parts of the saw teeth blades are sharp.

Further, the size of the puncture needle core is phi 4.0mm multiplied by 146 mm.

The technical effects of the utility model:

The utility model is used for bone and soft tissue aspiration biopsy sample, after rotatory cutting in earlier stage is carried out to the tissue, the utility model discloses a puncture biopsy needle enters into required tissue department of getting, extrudees the needle handle, and adjustable puncture biopsy needle gets into the degree of depth of tissue, makes the utility model discloses puncture biopsy needle presses close to tissue sample department, advances the puncture sleeve when taking out the puncture needle pistil to utilize the sawtooth of the telescopic hollow inlayer of puncture, the adjustment gets into the position and the degree of depth of tissue, and with target tissue and next door tissue separation, slowly take out hollow inlayer at last again, make hollow outer elasticity zigzag blade draw in, when drawing in, because zigzag blade's sharpness, can be simultaneously with the tissue cutting, in the blade entering tube that draws in behind the required tissue cutting along with. The puncture sleeve is withdrawn to obtain the required tissue. Through the combined use of puncture needle pistil, hollow inlayer and hollow skin, can say that required tissue takes out convenient and fast, need not extra grasping tool, protected peripheral vascular nerve simultaneously, improved the factor of safety of operation.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example (b):

as shown in figures 1-4, a novel bone and soft tissue biopsy needle comprises a puncture needle core and a puncture sleeve which are nested with each other, wherein the tail end of the puncture needle core is a needle handle 1, and the front end of the puncture needle core is a needle point 2; the puncture sleeve consists of a hollow inner layer and a hollow outer layer which are mutually nested, the tail end of the hollow inner layer is provided with a handle 3, and the front end of the hollow inner layer is provided with uniformly distributed sawteeth 4; the tail end of the hollow outer layer is provided with a handle 5 which is also used as a baffle, and the front end is provided with a sawtooth-shaped blade 6 which can be elastically closed.

Further, the length of the puncture needle core is 1cm longer than that of the puncture sleeve.

Further, the length of the hollow inner layer is 0.5cm longer than the length of the hollow outer layer.

furthermore, the sawteeth 4 of the hollow inner layer and the sawteeth blades 6 of the hollow outer layer are made of stainless steel materials, and the ends of the sawteeth are sharp.

After the rotatory cutting in earlier stage is carried out to the tissue, pierce novel puncture biopsy needle and arrive required tissue department of getting, extrusion needle handle 1, the degree of depth that adjustable puncture biopsy needle got into the tissue, make novel puncture biopsy needle press close to tissue sample department, impel the puncture sleeve when taking out the puncture needle pistil, and utilize the sawtooth 4 of the telescopic hollow inlayer of puncture, the position and the degree of depth that the adjustment got into the tissue, and with target tissue and next door tissue separation, hollow inlayer is taken out slowly again at last, make hollow outer elasticity zigzag blade 6 draw in, when drawing in, because zigzag blade 6's sharpness, can be simultaneously with the tissue cutting, in the blade 6 admission pipe that draws in behind the required tissue cutting, it can obtain required tissue to take out the puncture sleeve.
