Abstract
The utility model provides an aspiration biopsy needle which comprises a tubular inner needle, wherein an outer needle is sleeved on the inner needle, one end of the outer needle is provided with a needle point, the other end of the outer needle is connected with a needle handle, a first biopsy hole is arranged in a place of the outer needle, which is close to the needle point, a second biopsy hole is arranged in a place of the inner needle, which corresponds to the first biopsy hole, and one end of the inner needle, which is provided with the second biopsy needle, is provided with a blind end. The aspiration biopsy needle has the advantages of larger one-time puncture sampling quantity, high biopsy efficiency, less puncture times, accurate puncture depth, safety and reliability, simple structure and convenience for use.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of aspiration biopsy pin.
Background technology
When occupying lesions such as tumor, cyst, enclosed mass are diagnosed, except imaging examinations such as the CT of routine, magnetic resonance, B ultrasonic, sometimes need carry out the biopsy sampling,, make last diagnostic through pathological tissues being done cytodiagnosis to pathological tissues.Common biopsy method comprises two kinds of operation biopsy, aspiration biopsies at present.Wherein, the operation biopsy is in table superficial part position pathological changes method commonly used, the method for usually taking aspiration biopsy deep to diseased region.Common aspiration biopsy now is to adopt syringe directly to thrust diseased region, carries out the aspirate tissue cell sampling.But syringe commonly used is less because of the aperture of syringe needle, and the pathological tissues that once can extract is less, and is prone to take place the needle tubing obstruction, needs repeated multiple times puncture sampling; And be difficult to definitely grasp paracentesis depth with syringe puncture, there is puncture to injure other internal organs excessively deeply, or the shallow problem that does not reach diseased region, sample of tissue mistake that punctured.This method is inefficiency not only, has increased patient's misery, and the possibility that stimulates the tumor diffusion is arranged.
The utility model content
The purpose of this utility model is to overcome the weak point of conventional syringe aspiration biopsy, and a kind of aspiration biopsy pin that a kind of biopsy efficient is high, puncture time is few, paracentesis depth is clear and definite is provided.
The purpose of this utility model reaches through following technical measures:
A kind of aspiration biopsy pin comprises piped interior pin, and interior needle guard is connected to outer pin, it is characterized in that: an end of outer pin is a needle point, and the other end of outer pin is connected with needle handle, and outer pin is provided with the first biopsy hole near the position of needle point; The corresponding position of the interior pin and the first biopsy hole is provided with the second biopsy hole, and the end that interior pin is provided with the second biopsy hole is a cecum.
Say that further needle handle is provided with locating hole, the end that interior pin is corresponding with needle handle is provided with Connection Block, and Connection Block is provided with and the corresponding locating piece of locating hole.Through the setting of locating hole and locating piece, can make the first biopsy hole and the second biopsy hole be easy to alignment, deflection does not take place.Have the hole that is connected with syringe on the Connection Block, can conveniently connect syringe.
As a kind of improvement, the outer surface of outer pin is provided with the length scale.The length scale that outer pin is provided with can make the operator control paracentesis depth easily.
In use, can locate the space occupying lesion position and the degree of depth with B ultrasonic, hand-held this aspiration biopsy pin of operator punctures, and the length scale on the pin is accurately controlled paracentesis depth in addition; After arriving diseased region, pin has or not blood to flow out in observing, when no blood flow goes out; Interior pin is connected syringe and with the suction of appropriate dynamics, the tissue of diseased region can be inhaled into the biopsy hole, pin in extracting out then; The portion of tissue that interior pin will suck the biopsy hole proposes, if a biopsy quantity not sufficient can be inserted interior pin again; And suction once more, also rotatable outer pin is to obtain the tissue of different parts.Like this, only need one-time puncture, just can obtain the biopsy of sufficient amount.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
(1) the one-time puncture sampling amount is big, biopsy efficient is high, puncture time is few;
(2) paracentesis depth is clear and definite, safe and reliable;
(3) simple in structure, easy to use.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described further.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of aspiration biopsy pin of this utility model embodiment;
Accompanying drawing 2 is cutaway views of a kind of aspiration biopsy pin of this utility model embodiment.
The specific embodiment
Embodiment: with shown in the accompanying drawing 2, a kind of aspiration biopsy pin comprises piped interior pin 11 like accompanying drawing 1, and interior pin 11 is socketed with outer pin 3, and an end of outer pin 3 is a needle point 1, and the other end of outer pin 3 is connected with needle handle 5, and outer pin 3 is provided with the first biopsy hole 2 near the position of needle point 1; Interior pin 11 and 2 corresponding positions, the first biopsy hole are provided with the second biopsy hole 10, and the end that interior pin 11 is provided with the second biopsy hole 10 is a cecum.
Needle handle 5 is provided with locating hole 6, and interior pin 11 is provided with Connection Block 8 with needle handle 5 corresponding ends, and Connection Block 8 is provided with and locating hole 6 corresponding locating pieces 7.Through the setting of locating hole 6 and locating piece 7, can make the first biopsy hole 2 and the second biopsy hole 10 be easy to alignment, deflection does not take place.Have the hole 9 that is connected with syringe on the Connection Block 8, can conveniently connect syringe.
The outer surface of outer pin 3 is provided with length scale 4.The length scale 4 that outer pin 3 is provided with can make the operator control paracentesis depth easily.
In use, can locate the space occupying lesion position and the degree of depth with B ultrasonic, hand-held this aspiration biopsy pin of operator punctures, and the length scale on the pin 34 is accurately controlled paracentesis depth in addition; After arriving diseased region, have or not blood to flow out in the hole 9 of pin 11 in observing, when no blood flow goes out; Interior pin 11 is connected syringe and with the suction of appropriate dynamics, the tissue of diseased region can be inhaled into the biopsy hole, pin 11 in extracting out then; The portion of tissue that interior pin 11 will suck the biopsy hole proposes, if a biopsy quantity not sufficient can be inserted interior pin 11 again; And suction once more, also rotatable outer pin 3 is to obtain the tissue of different parts.Like this, only need one-time puncture, just can obtain the biopsy of sufficient amount.
