Description

Tumor sampler

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to tumour sampler.

Background

The tumor is an abnormal lesion formed by clonal abnormal hyperplasia caused by that certain cells of local tissues lose normal regulation and control on the growth of the local tissues on the gene level under the action of various carcinogenic factors of an organism. However, the tumor is also divided into malignant tumor and benign tumor, and the pathological analysis of the tumor needs to sample and analyze the interior of the tumor, for example, the patent with the patent publication number of CN203074760U, when the puncture tube is punctured into the tumor tissue, the tumor tissue will sink into the sampling hole, then the sampling rod is pulled backwards, the cutting knife will cut and collect the tumor tissue sunk into the sampling hole, and finally the tumor is taken out for inspection.

Although this patent enables the removal of tumor tissue at different depths, these tumor tissues are collected together and pulled out by the sampling rod, and the tumor tissues at different depths are not separately collected, so that the tumor tissues at different depths cannot be examined.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a tumor sampler to solve among the prior art the unable problem that separately collects of realization of the tumour tissue of different depth.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a tumor sampler, includes the puncture tube, the one end of puncture tube is the toper, the intraductal thief rod that is equipped with of puncture, the one end of thief rod be equipped with the scraper of puncture inner wall butt, the other end of thief rod stretches out the puncture outside of tubes, the sampler is still including collecting the mechanism, it includes a plurality of thief holes that are located the different periphery of puncture tube respectively to collect the mechanism, the thief rod is equipped with the collecting vat that matches the use with the thief hole, the collecting vat extends to the scraper.

The utility model discloses a theory of operation: when carrying out tumour tissue sample, insert the tumour with the puncture pipe in, tumour tissue will be absorbed in the thief hole, draws the thief rod backward after that, and the scraper will be cut the tumour tissue who is absorbed in the thief hole. Because a plurality of thief holes are located the different periphery of puncture pipe respectively, consequently tumour tissue is absorbed in the thief hole from different degree of depth and position, be equipped with the collecting vat that matches and use with the thief hole on the thief rod simultaneously, tumour tissue is absorbed in to the collecting vat, because the collecting vat extends to the scraper, during the pulling scraper, the scraper is with the tumour tissue cutting back in the corresponding thief hole, fall into corresponding collecting vat respectively in, and along with the thief rod is pulled out outside the puncture pipe, take off the tumour tissue of collecting vat respectively, the realization is examined the tumour tissue of the different degree of depth.

The utility model has the advantages that: this application utilizes the collecting vat that is in on the different periphery and matches the thief hole of using with it, realizes that the inside different degree of depth tumour tissue's of tumour cut alone and collect, realizes examining the tumour tissue of the different degree of depth.

Further, the other end of the sampling rod is connected with a handle. The sampling rod can be conveniently pulled to sample through the pulling handle.

Further, the external diameter of sample rod is the same with the internal diameter of puncture pipe, the length of collecting vat is the same with the length of sample rod. The purpose that sets up like this can cut the tumour tissue accuracy that gets off and fall into to collect the inslot, conveniently collects, avoids the failure of sample.

Furthermore, one side of the scraper facing the handle is provided with a cutting edge. Through setting up the blade, cutting tumour tissue that can be quick.

Further, the opening size of the collecting tank gradually increases toward the inside of the collecting tank. The opening that the aim at collecting vat that sets up like this is little and its inside big, and tumour tissue gets into to accomplish the cutting back in collecting vat like this, can prevent that the tumour from dropping from the collecting vat when taking out the thief rod.

Drawings

FIG. 1 is a schematic view of the internal structure of a tumor sampler of the present invention;

fig. 2 is the external structure diagram of the tumor sampler of the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: handle 1, thief rod 2, tumour tissue 3, collecting vat 4, scraper 5, puncture tube 6, thief hole 7.

Example 1: as shown in fig. 1 and 2: the utility model provides a tumor sampler, including puncture tube 6, the one end of puncture tube 6 is the toper, be equipped with thief rod 2 in the puncture tube 6, the one end of thief rod 2 is equipped with the scraper 5 with 6 inner wall butts of puncture tube, the other end of thief rod 2 stretches out puncture tube 6 outer and be connected with handle 1, the sampler is still including collecting the mechanism, it includes 2 sampling holes 7 that are located the different periphery of puncture tube 6 respectively to collect the mechanism, thief rod 2 is equipped with the collecting vat 4 that matches the use with sampling hole 7, collecting vat 4 extends to scraper 5, the external diameter of thief rod 2 equals the internal diameter of puncture tube 6.

When the tumor tissue 3 is sampled, the puncture tube 6 is inserted into the tumor, the tumor tissue 3 sinks into the sampling hole 7, then the sampling rod 2 is pulled backwards, and the tumor tissue 3 sunk into the sampling hole 7 is cut by the scraper 5. Because 2 thief holes 7 are located the different periphery of puncture pipe 6 respectively, consequently tumour tissue 3 sinks into thief holes 7 from the different degree of depth and position, be equipped with simultaneously on thief rod 2 and match the collecting vat 4 of using with thief holes 7, tumour tissue 3 sinks into collecting vat 4, because collecting vat 4 extends to scraper 5, during pulling scraper 5, after the tumour tissue 3 cutting in corresponding thief holes 7 of scraper 5, fall into corresponding collecting vat 4 respectively, and outside being pulled out puncture pipe 6 along with thief rod 2, take off the tumour tissue 3 of collecting vat 4 respectively, the realization is examined tumour tissue 3 of the different degree of depth.

Example 2: example 2 differs from example 1 only in that: the opening size of the collecting gutter 4 increases gradually towards the inside of the collecting gutter 4. The opening that the aim at collecting vat 4 that sets up like this is little and its inside big, and tumour tissue 3 gets into and accomplishes the cutting back in collecting vat 4 like this, can prevent that the tumour from dropping from collecting vat 4 when taking out thief rod 2.

It should be noted that, for those skilled in the art, without departing from the structure of the present invention, many modifications and improvements can be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
