Specific sampler for gastrointestinal tumor biopsy tissue

Abstract

The invention relates to the technical field of medical appliances, and particularly relates to a specific sampler for a gastrointestinal tumor biopsy tissue. The sampler comprises a battery cartridge, a rear tube head, a rubber tube and a front tube head, wherein a cap is arranged on the battery cartridge, and dry batteries are arranged inside the battery cartridge; the battery cartridge and the rear tube head are connected and fixed; front and rear ends of the rubber tube are respectively connected with the front tube head and the rear tube head; a micro-camera and an LED bead are arranged at the opening part of the front end of the front tube head; a sampling knife component is arranged on the side wall of the front tube head, and is provided with a pulling wire; and a pulling ring is fastened at the end part, extending out of the rear tube head, of the pulling wire. The sampler has reasonable structure design, a visual operation environment is provided by adopting combination of the rubber tube and the metal tube head with the micro-camera and the LED bead, and the opening and closing states of the sampling knife on the side wall can be controlled for sampling a tumor tissue in a narrow digestive tract. The sampler has the advantages of simple and convenient operation and time and labor saving, is safe and reliable, and can be used for improving the diagnosis efficiency of medical staff and reducing the pain of patients.

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. In order to solve this problem, those skilled in the art have invented professional samplers, such as the digestive tract tumor biopsy sampler whose authorized announcement number is CN201631234U, and the digestive tract tumor biopsy sampler whose authorized announcement number is CN203107168U. The scraper is set on the arm, and the patient does not need to swallow the air bag, and directly uses the scraper for biopsy sampling. Altho...

Problems solved by technology

[0002] Clinically, in order to diagnose 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 cumbersome, and the doctor is laborious. more painful

In order to solve this problem, those skilled in the art have invented professional samplers, such as the digestive tract tumor biopsy sampler whose authorized announcement number is CN201631234U, and the digestive tract tumor biopsy sampler whose authorized announcement number is CN203107168U. The scraper is set on the arm, and the patient does not need to swallow the air bag, and directly uses the scraper for biopsy sampling. Although the sampler with the above structure does not need to swallow the air bag, the protruding scraper will affect the oral cavity, digestive tract when it is inserted and withdrawn into the digestive tract. Do not cause harm, very unsafe to use

[0003] The announcement number is CN205107768U's digestive tract tumor biopsy sampler, which solves the above problems by setting a sampling knife on the side wall of the front end of the hose, but its structure is limited: 1. The pulley structure can not actually drive the working part through the control part. (scraping blade); 2. No visual environment is provided, the operation depends on the feel, and the timing of tissue sampling depends entirely on the experience of the operator; 3. The guide ball in the structure cannot play a guiding role in the application, and hinders the normal operation of the sampling knife assembly. Operation
