Visualized puncture device

Abstract

The invention discloses a visualized puncture device. The device comprises a puncture needle and a puncture casing pipe which is used in cooperation with the puncture needle, and the puncture needle is inserted in the puncture casing pipe; the puncture needle comprises a handle, one end of the handle is connected with a puncture rod, the end of the puncture rod is connected with a transparent puncture head, a PCB, a camera and a light set are arranged inside the puncture rod, the light set is arranged at the periphery of the camera in a surrounding mode, and the camera and the light set are electrically connected with the PCB; the puncture casing pipe comprises a puncture casing pipe seat located at one end of the puncture casing pipe and an outer puncture casing pipe fixedly connected with the puncture casing pipe seat. When the visualized puncture device penetrates, illumination is provided for the puncture device through the light set, then real-time shooting is conducted through the camera, therefore medical care personnel can observe the puncture position and the puncture condition in real time, and it is convenient to conduct precise surgical puncture; in addition, a folded sealing cap is arranged in the puncture casing pipe seat, and due to the fact that the folded sealing cap is closely attached to the puncture needle, the sealing and fixing effects are achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a visual puncture device. Background technique [0002] Minimally invasive surgery represented by laparoscopy is developing faster and faster in the medical field. Minimally invasive surgery characterized by small surgery and small trauma has been recognized and recognized by the majority of medical staff. The cannula trocar is an essential instrument for establishing surgical channels and observation channels in abdominal surgery. The trocar usually includes a sleeve base as an access channel for other surgical instruments, a conversion cap arranged on the sleeve base, and a puncture rod passing through the sleeve base and the conversion cap. First of all, in order to penetrate the skin, cut the epidermis of the skin with a scalpel, then use the puncture rod to penetrate the skin and enter the body cavity together with the sleeve seat and the conversion cap, and then pull out...

AI Technical Summary

Problems solved by technology

It is an extremely important task to set the visual function on the puncture device in the above process, but the position captured by the camera of the puncture device in the prior art is the side of the puncture center point, and the position of the puncture tip cannot be photographed. It was only photographed after passing through, so it cannot achieve the effect of real-time puncture and camera very well

Moreover, the puncture sleeve and the puncture seat in the prior art are mostly connected by a connection mechanism. Due to the difference in the connection structure, air leakage occurs at the joint between the puncture sleeve and the puncture seat, which makes the overall seal of the puncture device poor performance
