Abstract

The invention discloses a puncture assembly. The puncture assembly comprises a control handle and a puncture needle, wherein the control handle comprises a body part and a pushing part, the pushing part is mounted on the body part, and the pushing part can move on the body part in the first direction; the puncture needle comprises an extension part extending in the first direction and a needle point part used for puncturing biological tissue, and the extension part is fixedly connected to the pushing part; and when the control part moves on the body part, the control part can drive the puncture needle to move in the first direction so as to control the puncture needle to puncture out and withdraw. According to the puncture assembly provided by the invention, through the arrangement of the control handle, the pushing part on the control handle is moved, so that the puncture needle can be controlled to puncture out and withdraw, a user can conveniently control the puncture needle, the puncture action of the puncture needle is controlled by the pushing part, and the user can conveniently control puncture force.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a puncture assembly for puncturing biological tissues. Background technique [0002] With the development of interventional technology, the demand for puncture components in interventional diagnosis and treatment operations is becoming increasingly urgent. Interventional diagnosis and treatment technology is an operation technology that uses puncture needles, dilators, sheaths and other instruments to conduct diagnosis and treatment through blood vessels under the guidance of medical imaging equipment. However, in the existing puncture assembly, the process of cooperation between the various parts is complicated and the manipulation is inconvenient. [0003] Therefore, in view of the above technical problems, it is necessary to provide a new piercing assembly. Contents of the invention [0004] The purpose of the present invention is to provide a puncture assembly, which ca...
