Abstract

The invention belongs to the field of medical instruments, and particularly discloses a thoracocentesis mirror comprising a thoracocentesis mirror body and a sheath. The thoracocentesis mirror body comprises a needle-shaped hard working end, an operation portion, a light source connector, an image output end and a drainage passage which are communicated mutually. The sheath comprises a rigid sheath head and at least one passage and is disposed on the periphery of the needle-shaped hard working end; and a front end of the needle-shaped hard working end is provided with an optical lens and an optical fiber output end. The thoracocentesis mirror combines the advantage of a puncture needle capable of puncturing skins and tissue to get into a human body, and the advantage of an endoscope capable of providing inside view images for doctors; and when using the thoracocentesis mirror for puncture, the doctors no longer perform puncture depending on experience and judgment with certain blindness, but operate under direct view of a monitor, and accordingly operation safety is improved.

Description

Technical field [0001] The invention belongs to the field of medical instruments, in particular a thoracic puncture mirror. Background technique [0002] The puncture needle, including a needle core and a needle seat, has a scale, and belongs to interventional radiology equipment. In interventional radiology operations, the skin is punctured to further guide the interventional radiology equipment into the body. The current puncture needles are divided into: single-wall puncture needles, two-component trocars, three-component trocars, interatrial septal puncture needles, and peeling puncture needles. [0003] In addition, someone also developed the patent number 201220024568.3, the announcement number CN202446544U named a utility model patent of a thoracic puncture device, the thoracic puncture device includes a syringe, a drainage tube connected to the injection port of the syringe, and a drainage tube The needle on the tube is provided with a drainage port on the side wall of one...
