Tumor biopsy sampling device for medical clinic

Abstract

The invention discloses a tumor biopsy sampling device for medical clinic. The device comprises a sampling device body and a sampling cylinder, a storage box is fixedly arranged on the surface of theupper end of the sampling device body, a hydraulic pump is fixedly arranged on the surface of the lower end in the storage box, a hydraulic rod is arranged on one side of the hydraulic pump in a transmission manner, a supporting plate is fixedly arranged at one end of the hydraulic rod, a sampling cylinder is fixedly arranged at one end of the supporting plate, and a plurality of universal wheelsare fixedly arranged on the surface of the lower end of the sampling device body. A second stepping motor is started again to drive a needle cylinder outer sleeve hemming pressing plate to continuously descend, a sampling needle cylinder body compresses a spring, the needle head is pierced into tumor, then the compressing is stopped, at the moment, a driving motor drives an electric push rod to contract, the sampling needle cylinder pressing rod cap is clamped at the lower end of the sampling needle cylinder pressing rod cap, a piston rod is lifted and pulled to move, a sample is extracted, once the operation fails, the other needle head can be rapidly reset and replaced for sampling, shaking is avoided, the success rate is high, and the pain of a patient is reduced.

Description

technical field [0001] The invention relates to the technical field of tumor biopsy, in particular to a tumor biopsy sampling device for medical clinical use. Background technique [0002] The digestive system consists of two parts, the alimentary canal and the digestive glands. Digestive canal: including oral cavity, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum) and large intestine (cecum, appendix, colon, rectum, anal canal). Clinically, the section from the oral cavity to the duodenum is often called the upper gastrointestinal tract, and the part below the jejunum is called the lower gastrointestinal tract. There are two types of digestive glands: small digestive glands and large digestive glands. The small digestive glands are scattered in the walls of the digestive canal. The large digestive glands have three pairs of salivary glands (parotid glands, submandibular glands, and sublingual glands), liver and pancreas. The digestive system is one...

Problems solved by technology

[0003] However, the existing devices also have the following problems in use: first, when sampling the patient's tumor, the sampling personnel will cause the sample to be unstable due to hand shaking, thereby causing pain to the patient; When sampling the tumor, the preparation work is very long. Once the sampling fails, it cannot be re-sampled immediately, which is a waste of time
