Abstract

The invention discloses a pneumatic catheter feeding device for remotely operating trachea cannula. The device comprises a pneumatic pushing mechanism, a catheter clamping mechanism, a catheter and anopener fixing mechanism, wherein the pneumatic pushing mechanism is fixedly connected with the catheter clamping mechanism and the opener fixing mechanism; and the catheter penetrates through transverse limiting holes of the catheter clamping mechanism and the opener fixing mechanism in sequence. The device is low in total weight, small in size and convenient to carry; the travel of the pneumaticpushing mechanism is small, so that the feeding process can be precisely controlled; the all-pneumatic driving is adopted, so that the cost is saved compared with common motor driving, and the possibility is provided for large-batch production and once use design; the catheter feeding uses a pneumatic clamping mode to provide higher feeding force; and the slippage is not easy to occur, so that the feeding effect is more stable.

Description

technical field [0001] The invention relates to a technology in the field of medical equipment, in particular to a pneumatic catheter feeding device for remote operation of a tracheal intubation. Background technique [0002] Most of the existing robotic devices for endotracheal intubation are bulky, difficult to fix, and difficult to carry to the rescue site. A small amount of written equipment mostly adopts rigid mechanisms, which are easy to cause damage to patients during operation, and the use of motor drives makes it difficult to disengage the catheter. In addition, existing endotracheal intubation devices have not yet had a feeding device capable of continuous and stable catheter delivery. Therefore, it is of positive significance to invent a pneumatic rigid-flexible coupled pneumatic catheter feeding device that can improve the success rate of teleoperation surgery and reduce costs. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in ...
