Abstract

The invention provides a catheter pushing device. The device comprises a guide catheter needle, a pusher body, a pushing roller, a clutch, a pushing hand wheel, a self-rotating hand wheel, a catheter protection tube, a parallel rudder, a cardan joint, a cantilever, a self-locking joint, a vertical column, a base, a pusher assembly and a frame assembly. The pusher assembly comprises the guide catheter needle, the pusher body, the pushing roller, the clutch, the pushing hand wheel, the self-rotating hand wheel and a catheter protection tube. The pusher body is installed at the left end of the guide catheter needle. The self-rotating hand wheel is installed at the left end of the pusher body. The center of the pusher body is provided with the pushing hand wheel. According to the catheter pushing device, the pushing hand wheel and the self-rotating hand wheel are provided with microscales, therefore the penetration length and angle of the catheter can be precisely adjusted to facilitate the quantitative analysis by the medical personnel, the device is both stable and accurate. The arranged pusher assembly can be conveniently detached. Before use antiseptic treatment is necessary to the pusher assembly. The device can be used repeatedly, and the cost is reduced.

Description

Technical field [0001] The present invention relates to the technical field of medical equipment, in particular to a catheter pushing device. Background technique [0002] In the existing catheter intervention operations, medical staff can only slowly penetrate the catheter into a blood vessel or other body lumen based on experience. Due to the limitation of the operating space and the size of the catheter, it is often difficult to hold the catheter in a constant or predetermined manner. Accurate penetration rate. In addition, medical staff cannot make precise quantitative analysis of the length, position and strength of the penetrating catheter, and the increased labor intensity of medical staff will further affect the effect of the operation. The purpose of the present invention is to solve the problem of difficult operation in the existing catheter intervention surgery, and propose a catheter pushing device for assisting medical staff to accurately and simply push the cathete...
