Description

A kind of deep harmful structure strikes off cleaning and takes biopsy device

Technical field

The utility model belongs to medical instruments field, in particular to biopsy is cleared up and taken in striking off for a kind of deep harmful structure Device.

Background technique

Referred to as " biopsy ", also known as surgical pathology inspection referred to as " is examined " outside for biopsy (biopsy)；Refer to and sees patients Disconnected, treatment needs cut from patient's body, clamp to take or puncture etc. and take out pathological tissues, carry out the technology of pathological examination.This It is most important part in Diagnosis pathology, specific histopathological diagnosis, quilt can be made to most inspection cases As clinical final diagnosis.

Have requirement below for biopsy specimen: (1) position of drawing materials is accurate, to avoid necrotic tissue or obvious secondary sense Area is contaminated, is drawn materials in the intersection of lesion and normal tissue, it is desirable that gets pathological tissues and a little normal tissue of surrounding, size one As be advisable with 1.5cm × 1.5cm × 0.2cm.(2) materials should have certain depth, it is desirable that parallel with lesion depth vertical to cut It takes, Gastric mucosa biopsy should include muscularis mucosae.(3) there is chamber mark wood that should take each layer of tube wall；It should be use up when tunicate specimen sampling Amount is taken；The affiliated groups such as lymph node should all draw materials in case under the microscope.(4) it cuts or extruding should be avoided in when biopsy tissue, keep away Exempt from using tooth tweezer, so as not to metaplasia and influence to diagnose.(5) living tissue diameter is less than 0.5cm person, it is necessary to use cellophane paper or yarn Cloth is wrapped, in order to avoid lose.(6) it draws materials after decalcification processing should being carried out first containing bone tissue.

Most common biopsy tool is hook-type needle, using the crotch of hook-type needle front end by the portion of tissue hook in lesion Out, but using effect is undesirable, and often the tissue of crotch removal is not lesion tissue.To solve the above-mentioned problems, to existing Biopsy sampling instrument also improved, Chinese patent CN02267880.8 discloses a kind of vacuum suction cutting tissue biopsy Needle has the outer needle of needle stand including a front end with needle point, rear end, and outer needle is the blind hole pipe that there is side opening in a front end, One hollow needle is housed, the front end side and outer needle side opening corresponding position of the hollow needle are with an inside in the blind hole of outer needle Hole, the rear end of interior core needle is with hollow needle stand, and the cylindrical body of hollow needle stand front end is connected with the circular hole of needle stand, hollow needle stand Rear end connecting hole be connected to form with negative pressure source.

But existing improved tool is perhaps excessively complicated or is not easy to sample deep tissue, therefore needs a kind of simple easy Biopsy device is taken for deep tissue in operation.

Utility model content

The purpose of this utility model be in view of the drawbacks of the prior art, provide it is a kind of it is simple it is easily operated for deep not Biopsy device is cleared up and is taken in striking off for good tissue.

To achieve the goals above, the utility model uses following technical scheme: a kind of deep harmful structure strikes off clearly Manage and take biopsy device, comprising: protective case, head cleaning bar and take biopsy stick；Wherein the head cleaning bar is hollow barred body, Head is provided with cleaning brush head, and tail portion is provided with hollow handle, and the cleaning brush head is spheroidal；It is described to take during biopsy stick includes Blank pipe, multi-layer annular biopsy folder, metal pushrod and throw-out collar；Wherein the multi-layer annular biopsy folder is that a heel piece shape metal wire is close Arrangement is formed, and the bottom of the multi-layer annular biopsy folder is fixed at the top of hollow tube, and the top of sheet metal tabs connects metal One end of push rod, the other end of the metal pushrod pass through hollow tube and are fixed on throw-out collar, push up throw-out collar, metal pushrod pushes away Dynamic multi-layer annular biopsy folder opens；It is described to take biopsy stick fixed placement in the hollow barred body and hollow handle of head cleaning bar, Multi-layer annular biopsy folder stretches out outside cleaning brush head, and throw-out collar stretches out outside hollow handle；The protective case is covered in head cleaning bar It is external.

Further, cleaning brush head is made of hard medical silica-gel, and pointed cone outstanding, brush head are provided on the brush head Spheroidal is divided into the first hemisphere and the second hemisphere, and the pointed cone density on the first hemisphere brush head is higher than the point on the second hemisphere brush head Cone.

Further, it is arc-shaped for clearing up the vertex of a cone of brush head pointed cone, wherein the radian of the second hemisphere pointed cone vertex of a cone is less than the The radian of the one hemisphere pointed cone vertex of a cone.

Further, the tail portion of biopsy stick hollow tube is taken to be provided with grab, the lower part of corresponding heads cleaning bar hollow handle Corresponding card slot is offered, grab can be caught in card slot and be fixed.

Further, the outer surface of head cleaning bar barred body is provided with scale, and the scale indicates that distance takes biopsy stick top The length in portion.

Further, hemispherical, taper or half elliptic are pressed from both sides in multi-layer annular biopsy.

Further, cleaning bar barred body in head is made of transparent plastic material, and surface is provided with scale.

Protective case is for protecting head cleaning bar and taking biopsy stick not by outside contamination, while the biopsy taken out can also It is temporarily saved with being maintained in protective case.The cleaning brush head of head cleaning bar is used to remove the slough of lesion tissue, takes work The multi-layer annular biopsy of check bar is pressed from both sides for taking out biopsy.When in use, protective case is removed, by entire head cleaning bar and is taken Biopsy stick protrudes into lesion depths, and the scale on the hollow barred body of head cleaning bar can measure the depth of lesion, first with cleaning brush head The slough on lesion surface is removed, the two-part pointed cone density of cleaning brush head is different, and the wedge angle degree of the pointed cone vertex of a cone is different, Ke Yigen According to carrying out selection use the case where lesion tissue.Later, pushing up throw-out collar opens biopsy folder, and unclamping again throw-out collar presss from both sides biopsy It restores to the original state while clamping lesion tissue sample, biopsy stick is put into protective case and is saved.Take biopsy stick can be from Taken out in the hollow barred body of head cleaning bar, head cleaning bar is extend into it is intralesional, from barred body tail portion injecting fluid, to lesion It is cleaned.

The utility model takes biopsy device structure novel, easy to use, while striking off cleaning harmful structure, may be used also Accurately to take out the biopsy specimen of deep tissues, while biopsy specimen can also temporarily be kept, have and greatly face Bed use value.

Detailed description of the invention
