Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

Fig. 1 shows a disposable cardiac catheter panoramic endoscopic and drug delivery device, which comprises an endoscopic unit, a drug delivery unit and an operation unit; the endoscope unit comprises a COMS chip cap 1, a transmission line and a universal rotary joint 2 connected with the COMS chip cap; the COMS chip cap is provided with a plurality of COMS micro cameras 11 at the top and the side ends; the transmission line comprises a camera cable 13 and an optical fiber cable 14; two ends of the camera cable are respectively connected with the display and the COMS micro camera; the optical fiber cable is connected with the light source, and the head of the optical fiber cable is arranged on the COMS chip cap to provide the light source for the COMS micro camera. The administration unit comprises a catheter 3 connected with the universal rotary joint, a plurality of through holes arranged on the catheter and a one-way valve 31 arranged on the through holes; the through hole is arranged at one end close to the universal rotary joint;

the catheter is provided with a drug administration inlet 32 at a position far away from the universal rotary joint; the administration inlet 32 is connected to the canister by a peristaltic pump. The operating unit includes a rigidity control wire 41; the rigidity control line is arranged in the universal rotary joint and the inner part of the guide pipe 3. The rigid control line and the camera cable can be integrated in the same output tube 42, and in order to not obstruct the drug delivery, the transmission line, namely the camera cable and the optical fiber cable, can also be integrated on the tube wall of the catheter; the rigidity of the rigid control line can control the advancing of the whole device and the steering of the universal rotary joint in vitro, but the rigidity of the rigid control line can not cause damage to the wall of the catheter or the wall of the vessel wall through the catheter; the same catheter stiffness does not cause pressure or injury to the vessel wall.
