Medical instrument based on tumor needle biopsy

Abstract

The invention provides a medical instrument based on tumor needle biopsy, and relates to the technical field of medical instruments. The medical instrument comprises a mounting part, wherein an alignment part is arranged at the bottom of the mounting part; a pushing part is arranged in the mounting part; and a puncturing part is arranged in the pushing part. The puncturing part is fixedly connected to the bottom of the pushing part, so that under pushing of the pushing part, the puncturing part is controlled to conduct puncture treatment on a patient, a transition pipe is slidably connected into the puncturing part, and the top of the transition pipe is clamped to the top of a rotating part, so that the transition pipe does not move along with the puncture part; and when the pushing part rotates to the bottom, the circular-ring-shaped protruding structure of the outer wall of the bottom of the transition pipe is connected with the inner wall of the puncturing part, so that the sealing performance of the puncturing part is guaranteed, in the treatment process of the patient, active sample extraction and treatment liquid medicine input are facilitated through a plug part, and the problem in a puncture process that a puncture needle tube is long, a taking part is short, and pushing can not be easily carried out is solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical device based on tumor biopsy. Background technique [0002] Needle biopsy is a commonly used trauma interventional examination in clinical work. For example, tumors in the breast, body surface, or superficial parts of the liver can all be diagnosed through needle biopsy when the diagnosis cannot be made clearly. Needle biopsy will be equipped with special puncture equipment, such as a puncture gun, and most of the puncture needs to be assisted by imaging equipment such as ultrasound or CT, through which to locate and guide the puncture direction. [0003] However, as far as the current puncture instruments are concerned, the puncture needle tube is long and the holding part is short, which makes it difficult to advance during the puncture process, and most of the current puncture instruments rely on the doctor himself for alignment, and during the puncture proce...
