Abstract
This utility model relates to a kind of sampler for tumor autopsy.Piercing needle is generally adopted to sample for existing biopsy sampling, because one-time puncture can only get the sample of a point, representative poor, sometimes need sampling of repeatedly puncturing, bring the problem of larger sampling misery to patient.Sampler for tumor autopsy of the present utility model, comprise reducing hollow pipe, the top of described reducing hollow pipe is major diameter pipe, bottom is Small/mini-diameter Tube, the top of described reducing hollow pipe has top cover, the sampling probe head tube bundle made with Nitinol passes described top cover and penetrates in described Small/mini-diameter Tube, and described sampling probe head tube bundle top connects drawing handle, and described drawing handle is positioned at the upper end of described top cover.This utility model once can carry out multidraw, and the representativeness of sample obtained is strong, and patient punctures painful little.
Description
Technical field:
This utility model relates to a kind of sampler for tumor autopsy.
Background technology:
Biopsy is the steps necessary of diagnosing tumor, cuts, clamps and to get or pathological tissues is taken out in puncture etc., carry out the technology of pathological examination in patient body.Biopsy sampling is drawn materials at the intersection of pathological changes and normal structure, requires to get pathological tissues and a little normal structure of surrounding, and its size is generally advisable with 1.5cm × 1.5cm × 0.2cm.And draw materials and should have certain degree of depth, require parallel with the focus degree of depth vertically to cut.Existing biopsy sampling generally adopts piercing needle to sample, because one-time puncture can only get the sample of a point, representative poor, sometimes needs sampling of repeatedly puncturing, and brings larger sampling painful to patient.
Summary of the invention:
The purpose of this utility model is to provide a kind of sampler for tumor autopsy, once can carry out multidraw, and the representativeness of sample obtained is strong, and patient punctures painful little.
Above-mentioned object is realized by following technical scheme:
Sampler for tumor autopsy, comprise reducing hollow pipe, the top of described reducing hollow pipe is major diameter pipe, bottom is Small/mini-diameter Tube, the top of described reducing hollow pipe has top cover, the sampling probe head tube bundle made with Nitinol passes described top cover and penetrates in described Small/mini-diameter Tube, and described sampling probe head tube bundle top connects drawing handle, and described drawing handle is positioned at the upper end of described top cover.
Described sampler for tumor autopsy, described sampling probe head tube bundle comprises 4-8 sampling syringe needle, and each described sampling syringe needle toe lateral wall has one group of agnail type cutting blade, and the diameter of each described sampling syringe needle is 0.3-0.5mm, and internal diameter is 0.35-0.45mm.
Described sampler for tumor autopsy, has one group of jack base bottom described drawing handle, the jack base described in described sampling syringe needle inserts with and with described jack base interference fit.
Beneficial effect:
This utility model adopts the sampling probe head tube bundle having the Nitinol of memory function to make, first hold during sampling drawing handle upwards take out make syringe needle restrain be in completely in Small/mini-diameter Tube, then Small/mini-diameter Tube is thrust position to be sampled, thrust backward under push away drawing handle make syringe needle restrain stretch out Small/mini-diameter Tube, because sampling probe head tube Shu Caiyong has the Nitinol of memory function to make, therefore can launch to periphery, and then upwards pull drawing handle, in the process that sampling syringe needle upwards shrinks, agnail type cutting blade on syringe needle cuts the sample of tissue simultaneously, reach the object of one-time puncture multidraw, sampling has more representativeness, diagnostic result is more accurate.
Accompanying drawing illustrates:
Accompanying drawing 1 is the structural representation of this product.
Accompanying drawing 2 is structural representations of single syringe needle.
Detailed description of the invention:
As shown in Figure 1, the sampler for tumor autopsy of the present embodiment, comprise reducing hollow pipe 1, the top of described reducing hollow pipe is major diameter pipe, bottom is Small/mini-diameter Tube, and the top of described reducing hollow pipe has top cover 2, and the sampling probe head tube bundle 7 made with Nitinol passes described top cover and penetrates in described Small/mini-diameter Tube, described sampling probe head tube bundle top connects drawing handle 3, and described drawing handle is positioned at the upper end of described top cover.
Described sampler for tumor autopsy, described sampling probe head tube bundle comprises 4-8 sampling syringe needle 4, and each described sampling syringe needle toe lateral wall has one group of agnail type cutting blade 5, as shown in Figure 2, the diameter of each described sampling syringe needle is 0.3-0.5mm, and internal diameter is 0.35-0.45mm.
Described sampler for tumor autopsy, has one group of jack base 6 bottom described drawing handle, the jack base described in described sampling syringe needle inserts with and with described jack base interference fit.
Below be only most preferred embodiment of the present utility model, the technical solution of the utility model includes but not limited to the technical scheme disclosed in above-described embodiment, and unaccomplished matter of the present utility model belongs to the common practise of those skilled in the art.
