Abstract

The utility model discloses a visuable breast tumor rotary cutting biopsy needle, comprising a puncture needle 1, a suction cup 2, and a puncture needle deflection tube 3; the puncture needle 1 is inserted in the puncture needle deflection tube 3, a ring-shaped track groove 4 is arranged on the waist of the suction cup 2, and an arc guide rail 5 whose cross-section is round is fixed on the bottom of the puncture needle deflection tube 3; the arc guide rail 5 is fastened in the ring-shaped track groove 4, and the bottom of the suction cup 2 is provided with an inlet 6 of B ultrasonic probe card; the visuable breast tumor rotary cutting biopsy needle has the advantages that samples are taken exactly and rapidly, and the patient suffers little pain; the utility model can be widely used in the biopsy for breast tumor organization.

Description

Visual mammary gland tumor rotary-cut biopsy needle

Technical field

This utility model relates to a kind of improvement of mammary gland tumor biopsy needle, specifically a kind of visual mammary gland tumor rotary-cut biopsy needle.

Background technology

Mammary gland tumor is a common gynecological disease, clarify a diagnosis, in time treatment is very important, canceration lump particularly, if in time make a definite diagnosis, adopt operative treatment, its success rate is very high, its method of making a definite diagnosis mainly is to the laboratory examination of lump sample of tissue at present, when sampling, can be according to the ultrasound diagnosis picture position, with biopsy needle puncture sampling, the weak point that exists with this biopsy needle puncture sampling is: owing to be to calculate point of puncture according to the picture position estimation, after thrusting tissue, fully by estimation position and direction inserting needle, so the sample point error is bigger, be difficult for getting the core bit organization of lump, in addition, this sample time is longer, has increased patient's misery.

Summary of the invention

The purpose of this utility model is to provide a kind of easy adjustment puncture direction and depth of needle, can get the histioid visual mammary gland tumor rotary-cut biopsy needle of lump core position accurately and rapidly.

For reaching above purpose, the technical scheme that this utility model adopted is: this visual mammary gland tumor rotary-cut biopsy needle, by puncture needle, suction cup and puncture needle guide pipe constitute, puncture needle inserts in the puncture needle guide pipe, it is characterized in that establishing the annular orbit groove at the waist of suction cup, fixing section in the bottom of puncture needle guide pipe is circular arcuation guide rail, the arcuation guide rail is stuck in the annular orbit groove, the puncture needle guide pipe can be slided along the annular orbit groove on the one hand, on on the other hand can be in the ring-shaped guide rail groove, under rotate 30 the degree angles, establish Ultrasonic-B probe in the bottom of suction cup and snap in mouth.This utility model is also implemented by following measure: described puncture needle is made of needle cannula and nook closing member, on the end wall of needle cannula, establish the lump tissue and be pressed into mouth, establish the rotary-cut cutter in the end of nook closing member, after the lump tissue enters the lump tissue and is pressed into mouth, rotate nook closing member, then the lump tissue can be downcut and is enclosed in the needle cannula; The shape that described Ultrasonic-B probe snaps in mouth is consistent with the end of size dimension and Ultrasonic-B probe, and suction cup is made of transparent plastic, and the one, do not influence the B ultrasonic image, the 2nd, can see absorbing state to breast; Seat end at suction cup is also established negative pressure straw, aspirates by inserting negative pressure straw with syringe, makes to form negative pressure in the suction cup, and breast can suck in the suction cup.When using this utility model, the patient lies on the back, and suction cup is buckled on the patient's chest, by suction, breast is sucked in the suction cup, again Ultrasonic-B probe is inserted Ultrasonic-B probe and snap in the mouth, can on screen picture, show the lump position, at this moment, slip puncture needle guide pipe, and on adjusting, lower angle makes the axis direction of puncture needle guide pipe point to the core position of lump in the breast, determines depth of needle, can be along puncture needle guide pipe quick needle insertion, at this moment, can on the B ultrasonic screen picture, observe the position of puncture needle syringe needle in lump, then, rotate nook closing member, can take a sample, extract puncture needle, can take a sample finishes.

The beneficial effects of the utility model are: compare with the lump in breast biopsy pin of present use, owing to inserting needle under B ultrasonic directly monitors, and guider is arranged, so sampling accurately, fast, the patient suffering is little, can be widely used in the lump in breast biopsy.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,2,3.This visual mammary gland tumor rotary-cut biopsy needle, constitute by puncture needle 1, suction cup 2 and puncture needle guide pipe 3, puncture needle 1 inserts in the puncture needle guide pipe 3, establish annular orbit groove 4 at the waist of suction cup 2, fixing section in the bottom of puncture needle guide pipe 3 is circular arcuation guide rail 5, arcuation guide rail 5 is stuck in the annular orbit groove 4, puncture needle guide pipe 3 can be slided along annular orbit groove 4 on the one hand, can in ring-shaped guide rail groove 4, rotate up and down 30 degree angles on the other hand, establish Ultrasonic-B probe in the bottom of suction cup 2 and snap in mouth 6.Described puncture needle 1 is made of needle cannula 1a and nook closing member 1b, on the end wall of needle cannula 1a, establish the lump tissue and be pressed into a mouthful 1c, establish rotary-cut cutter 1d in the end of nook closing member 1b, after the lump tissue enters the lump tissue and is pressed into mouthful 1c, rotate nook closing member 1b, then the lump tissue can be downcut and is enclosed in the needle cannula 1a; The shape that described Ultrasonic-B probe snaps in mouth 6 is consistent with the end of size dimension and Ultrasonic-B probe, and suction cup 2 usefulness transparent plastics are made, and the one, do not influence the B ultrasonic image, the 2nd, can see absorbing state to breast; Seat end at suction cup 2 is also established negative pressure straw 7, aspirates by inserting negative pressure straw 7 with syringe, makes to form negative pressure in the suction cup 2, and breast can suck in the suction cup 2.
