Special sampler for biopsy tissue of digestive tract tumor

Abstract

The invention discloses a special sampler for biopsy tissue of digestive tract tumor. The special sampler includes a box. The left side of the box body is provided with a rubber pipe, the left end eccentric position array of the rubber tube is provided with four circular grooves 2, the right side of the circular groove 2 is provided with an LED lighting lamp, At that left end of the rub tube, a circular groove 1 is arranged at the cent of the four circular grooves 2, the side surface of the circular groove is provided with an annular stopper, At that left end of the annular stop, slide groovesare arrange at the upper and lower ends of the side surfaces of the circular groove 1, At that left end of the slide groove, four cameras are arranged in a side array of the circular groove 1. The right side array of the annular stopper is provided with four second electric telescopic rods, which can be inserted into and withdrawn from the digestive tract without causing harm to the mouth and thedigestive tract, and can be used very safely. At the same time, the tissue sample taken out can be adsorbed inside the annular knife to prevent the tissue sample from falling out during withdrawal.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a special sampler for digestive tract tumor biopsy tissue. Background technique [0002] Clinically, in order to confirm the nature of gastrointestinal tumors, biopsy samples must be taken. The traditional method is to let the patient swallow the airbag to expand the digestive tract, and then the doctor takes a biopsy sample with a hand-held instrument. This operation is more troublesome, and the doctor is more laborious. It is more painful. The existing biopsy samplers for digestive tract tumors all use a scraper on the soft support arm. The patient does not need to swallow the airbag, and directly uses the scraper for biopsy sampling. Although the sampler with the above structure does not need to swallow the airbag, it is convex. The scraper that is taken out will cause damage to the oral cavity and digestive tract when it is inserted into and extracted from the digesti...

[0002] Clinically, in order to confirm the nature of gastrointestinal tumors, biopsy samples must be taken. The traditional method is to let the patient swallow the airbag to expand the digestive tract, and then the doctor takes a biopsy sample with a hand-held instrument. This operation is more troublesome, and the doctor is more laborious. It is more painful. The existing biopsy samplers for digestive tract tumors all use a scraper on the soft support arm. The patient does not need to swallow the airbag, and directly uses the scraper for biopsy sampling. Although the sampler with the above structure does not need to swallow the airbag, it is convex. When the scraper is inserted into the digestive tract and pulled out, it will cause damage to the oral cavity and digestive tract, and it is very unsafe to use. At the same time, the tissue sample taken out is on the scraper, and the tissue sample will easily fall when it is pulled out and cannot be taken out.
