Medical tumor living body sampling inspection delivering device

Abstract

The invention discloses a medical tumor living body sampling inspection delivering device. The device comprises an accommodation pipe, the right end of the accommodation pipe is sealed, a through holeformed in the lower end of the right side face of the accommodation pipe is slidably connected with a sliding rod, the length of the moving rod is greater than that of the accommodation pipe, the left end of the side face of the moving rod is fixedly connected with the upper end of a scrapping knife, the scrapping knife is located on the left side of the accommodation pipe, an elliptical pipe iscoaxially fixed to the side face of the moving rod, the elliptical pipe is located in the accommodation pipe, and the side face of the elliptical pipe is slidably connected with the arc inner side ofan arc-shaped clamping plate. By means of the device, the damage of a sample when tumor living body of a patient is extracted is prevented, the contamination of the sample is effectively prevented, afirst permanent magnet is absorbed by a second permanent magnet, and the scrapping knife does not shake after sampling is conducted to prevent the damage on the sample to ensure the accuracy of the sample, an elastic device allows the arc-shaped clamping plate to be in contact with the outer side face of the elliptical pipe, the moving rod does not rotate at will, and therefore the sampling efficiency is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical tumor living body sampling inspection device. Background technique [0002] Clinically, before treating patients with tumors, it is necessary to test live tumors. In addition to extracting samples by means of negative pressure suction through syringes, there are also sampling methods such as scrapers in clinical practice. These sampling methods have certain problems. For example, the syringe will seriously damage the tissue and affect the diagnostic test. Increased the great difficulty of work; and the scraper needs to be transferred to the storage tool after sampling, and the sampling specimen is easily contaminated. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a medical tumor biopsy sampling inspection device, which avoids damage to the sample when extracting t...
