Description

Improved Disposable Gastroscope Live Sampler

technical field

The utility model relates to an improved disposable gastroscope living body sampler used in gastroenterology.

Background technique

At present, the gastroscope living body sampler used in the gastroenterology department of the hospital. The front end is to open the jaws by pushing the handle and the handle slider behind the handle to take multiple samples of stomach or esophagus tissue. After each sampling, the outer plastic tube needs to be pulled backwards to take out the tissue. The aforementioned operations need to be repeated many times. times to meet the required tissue sample volume. In addition, there is also a brush-type gastroscope living body sampler. After the brush is used to brush back and forth to take the sample, the outer plastic tube after the brush is pulled out, and the sample on the brush is brushed onto the glass slide, waiting for the next step of analysis and testing. The above-mentioned operation process is very cumbersome and takes a long time to complete the sampling. It is very inconvenient to use, which not only brings pain to patients, but also burdens medical staff. This situation has been perplexing medical personnel for a long time, and has become one of the important topics of research and development for medical personnel.

Contents of the invention

The purpose of the utility model is to solve the problems existing in the prior art, and provide an improved disposable gastroscope living body sampler which combines a forceps sampler and a brush sampler for single use. It is enough to receive the removed living body sample, etc., reducing the operation process, being convenient to use, and reducing the pain of the patient.

The technical scheme of the utility model is: an improved disposable gastroscope living body sampler, including a clamp head, a living body sample containing pool, a brush, an outer plastic tube, a handle, a guide wire, a handle slider behind the handle, a bracelet, and It is characterized in that: it is composed of a brush made of fluff on the outer plastic tube at the back of the forceps head, forming a conjoined single-use gastroscope living body sampler; the opening of the forceps head is provided with enough to receive the forceps to take a living body sample Arc-shaped living body sample storage pool; the front end of the living body sample storage pool is 0.1mm shorter than the front end of the forceps head.

The above-mentioned improved disposable gastroscope living body sampler has a closed diameter of the forceps head of 2.3 mm and a diameter of the forceps channel of 3.2 mm. The distance between the receiving forceps to collect the living sample is less than 0.8 mm from the forceps body, and can smoothly extend into the forceps channel.

Compared with the prior art, the utility model has the following advantages:

(1) The gastroscope biopsy sampler improved by the utility model is a one-piece single-use gastroscope biopsy sampler composed of a forceps head and a brush at the back of the forceps head. Doctors can choose one of the sampling methods according to specific conditions. Convenient and easy to operate.

(2) Under the opening of the clamp head, there is an arc-shaped living sample storage pool that is sufficient to receive the live sample. The front end of the arc-shaped living sample storage pool is 0.1mm shorter than the front end of the clamp head. If the body size is less than 0.8 mm, it will not affect the forceps operation; put the living samples in the arc-shaped living sample container into the formalin bottle, and then conduct pathological examination. It can reduce or avoid the repeated operation of forceps sampling, taking out the live forceps, and then putting the living sample into the formalin bottle, effectively reducing the operation process, reducing the pain of patients and the burden of medical staff.

(3) The arc-shaped living sample storage pool is processed to prevent damage to the surface of the gastric mucosa, smooth, without burrs, without edges and corners, etc.

See Fig. 1, an improved disposable gastroscope living body sampler, including forceps head 1, living body sample containing pool 2, hair brush (velvet); 3, outer plastic tube 4, handle 5, guide wire 6, and the handle is slippery behind the handle Block 7, bracelet 8, is characterized in that: it is provided with the brush 3 that fluff is formed on the external plastic tube 4 of forceps head and forceps head 1 rear part, forms conjoined single-use gastroscope living body sampler; One forceps head Below the opening is provided an arc-shaped living sample storage pool 2 (smooth surface, no thorns, no edges and corners) sufficient to receive the living sample taken by forceps; the front end of the living sample storage pool 2 is 0.1 mm shorter than the front end of the forceps head.

The above-mentioned improved disposable gastroscope living body sampler has a closed diameter of the forceps head of 2.3 mm and a diameter of the forceps channel of 3.2 mm. The distance between the receiving forceps to take the living sample is less than 0.8 mm from the forceps body and can smoothly extend into the forceps channel. .

Under the monitoring of the endoscope, the sterile sampling forceps enter the stomach or duodenum of the human body through the forceps channel of the endoscope, and the forceps head faces the lesion, push the handle 5 and the handle slider 7 behind the handle to open the jaws, close to the to be taken For living tissue, pull the handle 5 and the slider 7 behind the handle to close the jaws to take off the living sample, then push the handle 5 and the slider 7 behind the handle to open the jaws, and the removed living samples fall into the underside of the opened jaws. Living sample storage tank 2; repeat the above operation process repeatedly until the sampling is completed, pull the outer plastic tube 4 backward, take out the sampling forceps, put the living sample in the living sample storage tank 2 into a formalin bottle, and then conduct pathology test. If a brush is used for sampling, the brush moves back and forth at the sampling site, the sample is taken out, and the living sample on the brush is removed to the glass test piece for inspection.
