Abstract
The utility model relates to a biopsy needle, particular a rotary cutting biopsy needle, which is composed of a sleeve tube and a needle body, wherein both sides of the opening of the sleeve tube are provided with arc oblique edges, and the head of the needle body is correspondingly provided with a circular arc groove. The utility model is suitable for medical biopsy sampling, the volume of the sampled tissue is (relatively) larger, and the edge part is cut smoothly, which is convenient for making pathological sections and inspection.
Description
This utility model relates to a kind of biopsy needle, particularly a kind of rotary-cut biopsy needle.
Existing biopsy needle is to take out tissue through extruding or tearing when thrusting the back sampling, and distortion seriously is unfavorable for the biopsy inspection.
The purpose of this utility model is exactly to design a kind of rotary-cutting type biopsy needle that provides for addressing the above problem.
This utility model advances such realization, and the sleeve pipe 12 of biopsy needle is both sides arc hypotenuse swords, and head end one side of needle body has a circular groove corresponding with the hypotenuse sword.Thrust after needle body rotation, make the tissue that enters groove through the groove edge and the cutting of hypotenuse sword, can take out with needle body and check tissue.
The utility model has the advantages that: the tissue volume that rotary-cut is taken out is big (relatively), and the cutting of limit portion is neat, is convenient to check and make section.
Accompanying drawing 1 is looked sketch map for this utility model master;
Accompanying drawing 2 is this utility model schematic top plan view;
Accompanying drawing 3 is analysed and observe (amplification) sketch map for A-A.
Describe concrete structure of the present utility model in detail below in conjunction with accompanying drawing.
This utility model is made up of sleeve pipe 1 and needle body 2, and the head mouth of pipe of its middle sleeve 1 is a both sides arc hypotenuse sword 3, and needle body 2 corresponding heads have a circular arc type groove 4.Thrust the degree of depth for ease of grasp, can be carved with scale 5 outside the sleeve pipe 1.
Use this utility model thrusting when organizing, make the long tube wall place of subsides of groove 4 oral areas and sleeve pipe 1, thrust back rotation needle body 2 and make the groove mouth and make progress (direction shown in Figure 1), make to organize and just in time fall in the groove 4, rotate needle body 2 to 180 degree again organizer are cut and complete and separate tissue mutually through the edge and the hypotenuse sword of groove 4, and take out with needle body.
Claims (2)
1, a kind of rotary-cut biopsy needle is made up of sleeve pipe (1) and needle body (2), and the head mouth of pipe that it is characterized in that described sleeve pipe (1) is both sides arc hypotenuse swords (3), and the corresponding head of needle body (2) has a circular arc type groove (4).
2, biopsy needle as claimed in claim 1 is characterized in that can being carved with scale (5) outside the described sleeve pipe (1).
