Description
Technical field
Living sampling device technical field is the utility model is related to, more particularly to a kind of Vivo of Renal tissue penetration sampling
Pin.
Background technology
In clinical research and diagnosis, the position that study or diagnose is adopted frequently with the method for living body sampling
Sample.The position or tissue that to study or analyze are sampled, then the sample of taking-up is cultivated and examined, is obtained
With convincingness and targetedly result or conclusion.In the application for extracting a small amount of sample, living body sampling pin is a kind of important
Apparatus, because its surface of a wound is small, operation is flexibly widely accepted.
Kidney is the important metabolic organ of human body, renal fibroblast biopsy art abbreviation Renal biospy, to clear and definite kidney
Disease property and histological type, determine treatment policy, the important inspection method of judgement prognosis.Be applicable to asymptomatic proteinuria,
The treatment of a variety of symptoms such as albuminuria, acute nephritis treatment, primary nephrotic syndrome, Secondary cases or hereditary nephritis.
Existing Chinese patent CN201010154334.6 provides a kind of biopsy needle group that active organization's inspection is punctured for bone
Close, including solid puncture needle, there is the hollow pipe sampling probe of cone tubular front end, and in needle wall parallel to needle tubing axle
Section opening, and located at the edge needle tubing circumference of section opening one it is tangentially extending go out cutter.
But above-mentioned technology first has to solid puncture needle and service aisle sleeve pipe coordinating insertion group using complex
Knit, after solid puncture needle is taken out, by hollow pipe sampling probe from service aisle tail end of conduit insert, rotation hollow pipe sampling probe make
Purpose sample is separated with tissue, and its internal sample is drawn with copper bar after extraction hollow pipe sampling probe.The technical operation is complicated, and
Its internal sample distance is drawn with copper bar farther out, and sample may be caused necessarily to damage.
Utility model content
The purpose of this utility model is to provide a kind of Vivo of Renal tissue penetration sampling probe, solves existing renal tissue and wear
Pierce sampling probe trivial operations, the problem of internal wound is big.
To achieve the above object, above-mentioned technique effect is reached, the utility model solves above-mentioned ask by the following technical programs
Topic：
A kind of Vivo of Renal tissue penetration sampling probe, including hollow puncture tube, on the tube wall of the hollow puncture tube front end
Thief hole is offered, manages interior suit stored one kind of tubes；Sample storage groove is offered on the tube wall of the stored one kind of tubes front end, the edge of groove puts the first edge on a knife or a pair of scissors；
The thief hole is with sample storage groove in same axial position.
Sampling probe described in the utility model is ring set type needle body, is followed successively by stored one kind of tubes, hollow puncture tube from inside to outside, storage
Sample pipe and hollow puncture tube front end correspondence position have sample storage groove and thief hole, and stored one kind of tubes can rotate around its common axis line.
Edge structure is located at sample storage groove notch, just the focus in thief hole can be cut while sample storage groove is rotated, is cut
Tissue afterwards can be stored in sample storage groove.
By needle body insertion lesion tissue position, due to the interaction between pressure and tissue, part lesion tissue can sink into
In thief hole shrinkage pool, stored one kind of tubes is rotated, using the edge structure of sample storage groove edge, realizes the separation of sample tissue and body.This
The more existing method that cutter are extended to rotary-cut focus outside hollow pipe of method, the surface of a wound is smaller, and cleaved products recovery rate is high.
As a kind of above-mentioned improvement of Vivo of Renal tissue penetration sampling probe of the utility model, the hollow puncture tube front end
For solid prong structure, stored one kind of tubes top and solid prong structure interior side contacts.So, when can avoid being pierced into focus organ
Histocyte enters crack between stored one kind of tubes and hollow puncture tube, influences the relative rotation of stored one kind of tubes and hollow puncture tube；Simultaneously
Puncturing section integrated design can keep end face smooth, beneficial to puncture.
As a kind of above-mentioned improvement of Vivo of Renal tissue penetration sampling probe of the utility model, the thief hole is that arc is recessed
Hole.Lesion tissue designs arcuation shrinkage pool because the influence of internal pressure and cell-cell interaction forms convex surface in thief hole
More tissues can be made to enter in groove, while can also avoid lesion lump tissue from cannot be introduced into the situation of thief hole.
As a kind of above-mentioned improvement of Vivo of Renal tissue penetration sampling probe of the utility model, the stored one kind of tubes afterbody passes through
The hollow puncture tube mouth of pipe, tail end are provided with swing handle.The swing handle of stored one kind of tubes and tail end more than hollow puncture tube pipe shaft, profit are set
In rotation process.
As a kind of above-mentioned improvement of Vivo of Renal tissue penetration sampling probe of the utility model, the stored one kind of tubes afterbody tube wall
Position limiting slide block is set, and hollow puncture tube tail end inwall sets stopper slot corresponding with position limiting slide block.Stored one kind of tubes is controlled by sliding block
Around hollow puncture tube, it can guarantee that stored one kind of tubes and hollow puncture tube relative position are fixed in puncture process, prevent non-purpose tissue from entering
Enter in groove, while can also prevent that purpose tissue slides from notch in extraction.
The beneficial effects of the utility model are：
1st, by the stored one kind of tubes among rotating, it will sink into sample in sample storage groove and separated with body, it is more existing to prolong cutter
The surface of a wound is small for extending hollow pipe outside rotary-cut focus.
2nd, hollow puncture tube front end is solid prong structure, stored one kind of tubes top and solid prong structure interior side contacts, can be kept away
Histocyte enters crack between stored one kind of tubes and hollow puncture tube when exempting to be pierced into focus organ, influences stored one kind of tubes and hollow puncture tube
Relative rotation, while end face can be kept smooth, beneficial to puncture.
3rd, design arcuation shrinkage pool makes more tissues slip into groove, improves the utilization rate of sample storage groove.
It is big that the utility model can preferably solve the problems, such as that existing renal tissue punctures sampling probe trivial operations, internal wound.
