Description

Endoscopic tumor sampling device

Technical Field

The utility model relates to the technical field of medical equipment, specific theory especially relates to an peep formula tumour sampling device in.

Background

Tumor refers to a new organism formed by local tissue cell proliferation under the action of various carcinogenic factors, because the new organism mostly presents space occupying block-shaped protrusion, also called as neoplasm. The tumor disease is one of several serious diseases at present, this especially belongs to cancer the most serious, at the prior art to tumour diagnosis, it is most direct and accurate to detect with peeping formula, through the internal mode of direct entering, observe the detection to the tumor region, can carry out the sample simultaneously and draw, however, current peeping formula tumour sampling device is when gathering the sample, the current collection is constructed work efficiency low, often hardly gather corresponding sample, make patient's pain reinforcing, the result of use is relatively poor, current peeping formula tumour sampling device complex operation simultaneously, the later stage inspection maintenance is difficult.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an peep formula tumour sampling device to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: an endoscopic tumor sampling device comprises a handle, wherein a needle cylinder is fixedly connected to the handle, and a piston is movably arranged in the needle cylinder;

the novel needle-free infusion apparatus is characterized in that a guide wire cap is arranged at the rear end of the handle, the front end of the handle is connected with a needle sleeve, guide wires are arranged in the handle and the needle sleeve, the rear end of each guide wire is fixedly connected with the guide wire cap, and the front end of each guide wire is fixedly connected with a sampling needle.

Preferably, a silica gel sleeve is arranged on the periphery of one end, close to the handle, of the needle cannula.

Preferably, one end of the needle sleeve far away from the handle is provided with a protective cap.

Preferably, the guide wire cap is connected to the handle through threads.

Has the advantages that: compared with the prior art, the beneficial effects of the utility model are that: through the matching use of the guide wire cap, the guide wire and the sampling needle, the sampling needle can conveniently and accurately sample, the sampling efficiency is improved, and the sampling difficulty of medical staff is reduced; the silica gel cover is arranged, so that stimulation of the sampling device to the skin of a patient is avoided, and pain of the patient is relieved.

Drawings

Fig. 1 is a schematic view of the overall structure of an endoscopic tumor sampling device according to the present invention.

In the drawings: 1-handle, 2-guide wire cap, 3-silica gel sleeve, 4-needle sleeve, 5-protective cap, 6-sampling needle, 7-needle cylinder and 8-piston.

Detailed Description

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.

Examples

Referring to the attached drawings, in the embodiment of the present invention, an endoscopic tumor sampling device comprises a handle 1, a needle cylinder 7 is fixedly connected to the handle 1, and a piston 8 is movably arranged in the needle cylinder 7;

the novel needle cannula is characterized in that a guide wire cap 2 is arranged at the rear end of the handle 1, the front end of the handle 1 is connected with a needle cannula 4, guide wires are arranged in the handle 1 and the needle cannula 4, the rear end of each guide wire is fixedly connected with the guide wire cap 2, and the front end of each guide wire is fixedly connected with a sampling needle 6.

Furthermore, a silica gel sleeve 3 is arranged on the periphery of one end, close to the handle 1, of the needle sleeve 4.

Furthermore, a protective cap 5 is arranged at one end of the needle sleeve 4 far away from the handle 1.

Further, the guide wire cap 2 is connected to the handle 1 through threads.

The use process comprises the following steps:

when in use, before the sampling needle 6 is inserted into the biopsy hole, the guide wire cap 2 is pulled outwards, and the needle point is determined to be positioned in the end section metal protective cap 5; the needle sleeve 4 is taken out under the direct vision of the endoscope; the sampling needle 6 is recovered to the needle tip slope, so that the needle is conveniently sent to penetrate into the focus; pumping negative pressure from the needle cylinder 7, locking and fixing the piston 8, and collecting a specimen; removing the negative pressure, and taking the needle tip out of the body after the needle tip is recovered into the protective cap 5; 6 alignment slide glass of sampling needle, the push-out needle point pushes away the sample on the slide glass, can prevent that the sample from blockking up, is fixed in 95% alcohol with the sample and inspects.

In the process, the guide wire cap, the guide wire and the sampling needle are matched for use, so that the sampling needle can conveniently and accurately sample, the sampling efficiency is improved, and the sampling difficulty of medical personnel is reduced; the arrangement of the silica gel sleeve avoids the stimulation of the sampling device to the skin of the patient, and relieves the pain of the patient; the application has the advantages of simple structure, strong practicability and simple operation and is worth popularizing.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which 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.
