Background
Pathological puncture sampling is a common medical examination method used for diagnosing and treating various diseases. It is examined by inserting an elongated needle into human tissue and then taking a sample of the tissue out to determine the nature and extent of the lesion. Such techniques have been widely used in a variety of medical fields including oncology, internal science, surgery, etc.
The art of pathological puncture sampling dates back to the end of the 19 th century, when doctors began to take tissue samples using needles. Over time, this technology has been continually improved and perfected. At present, pathological puncture sampling has become a very common medical examination method and is widely applied to diagnosis and treatment of various diseases.
However, although pathological puncture sampling has been widely used, the existing sampling equipment is troublesome to operate. The main reason is that firstly, a needle core is inserted into the puncture needle to block the head end of the puncture needle when the puncture needle is used for puncture sampling, when the puncture needle approaches to pathological tissues, the needle core is taken out again, the sampling needle is reinserted to penetrate the pathological tissues to hook the sample, and finally, the sampling needle is pulled out, so that the needle insertion and the needle extraction are required to be repeated for a plurality of times, and the operation is troublesome.
