Abstract

The invention belongs to the field of medical apparatus and particularly relates to a peritonrocentesis mirror which comprises a puncture mirror main body and an expansion sheath, wherein the puncture mirror main body comprises a needle-shaped hard working end part, an operation part, a light source connector and an image output end, wherein at least one inflatable or air bag catheter access passage is arranged in the expansion sheath, and the expansion sheath is placed on the periphery of the needle-shaped hard working end part. The peritonrocentesis mirror effectively combines the advantages of a puncture needle and the functions of an endoscopem, namely the advantage of the puncture needle, that puncturing skin and tissue to enter a human body, and the advantage of the endoscope, that providing inward vision images to a doctor, are combined, the doctor uses the peritonrocentesis mirror directly puncture a target part to enter into an abdominal cavity expanded by injecting gas through a charging channel, so as to be convenient for directly viewing abnormal situations, such as bleeding and the like, to provide more objective and visualized materials to the doctor and to be convenient for the doctor to diagnose and cure.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a laparoscopic puncture mirror. Background technique [0002] The puncture needle, including a needle core and a needle seat, is graduated and belongs to interventional radiology equipment. During interventional radiology operations, it punctures the skin to further guide interventional radiology equipment into the body. The current puncture needles are divided into: single-wall puncture needles, two-part trocars, three-part trocars, atrial septal puncture needles and peeling puncture needles. In addition, someone has also developed a patent No. CN201110175712.3 and a notification No. CN102283695A, which is called a retractable laparoscopic puncture mirror. It includes a sheath and a core rod with a circular cross section. Cylindrical cavity, a core rod positioning mechanism is set on one side of the cavity, and a circular card hole slot is provided at the rear end of the core...
