Abstract

The invention discloses a liver sampling device and relates to the field of medical apparatuses and instruments in the internal medicine department. When the liver sampling device is used, a doctor holds a base and a supporting plate and puts the sample liver between a sampling tube and a sleeve. The doctor can oppositely press the base and the supporting plate with hand, a cutting edge of the sampling tube quickly cut off the liver tissue, the liver tissue serves as a sample for assay, and the sampling volume of the liver tissue can be very accurate. The liver sampling device is simple and convenient to operate, the sampling volume can be accurately controlled, and the successful liver tissue sampling efficiency can be improved.

Description

technical field [0001] The invention relates to the field of internal medical equipment, in particular to a liver sampler. Background technique [0002] Hepatic cysts and cirrhosis are common medical diseases. When treating liver diseases, doctors often need to cut a small piece of liver tissue for pathological anatomy, and then determine the treatment plan. The existing liver sampling device is only a simple scalpel and tweezers, it is difficult to control the amount of sampling, and it is very inconvenient to operate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liver sampler, which is simple and convenient to operate, can precisely control the sampling volume, and improves the success rate of liver tissue sampling. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] The liver sampler comprises a circular tube-shaped sampling tube and a sleeve,...
