Cardiac surgery clinical cardiovascular surgery intubation tube thruster

Abstract

The invention discloses a cardiac surgery clinical cardiovascular surgery intubation tube thruster, and relates to the technical field of cardiovascular surgery instruments, the cardiac surgery clinical cardiovascular surgery intubation tube thruster comprises a U-shaped groove plate and a pair of square plates fixed at the lower end part of the U-shaped groove plate, a circular shaft is rotatably connected between the two square plates, and the circular shaft is fixedly sleeved with a driving wheel; a short shaft is rotationally connected to the inner side of the U-shaped groove plate, the short shaft and the circular shaft are in transmission connection through a belt wheel transmission assembly, the short shaft is fixedly sleeved with a gear, a driving mechanism located on the upper side of the gear is arranged on the U-shaped groove plate, and a limiting circular rod is longitudinally arranged in the U-shaped groove plate. The two ends of the limiting round rod penetrate through the inner side front wall and the inner side rear wall of the U-shaped groove plate correspondingly, and limiting discs are fixed to the two ends of the limiting round rod correspondingly. The operation is simple, the operation can be realized by one hand, the operation process is stable, and the accuracy is high.

Description

technical field [0001] The invention relates to the technical field of cardiovascular surgery instruments, in particular to an intubation propeller for clinical cardiovascular surgery in cardiac surgery. Background technique [0002] The intubation pusher is a device for inserting a medical catheter into the human body during surgery. This device can improve the accuracy and stability of the intubation operation to a certain extent; in heart or great vessel surgery , It is often necessary to insert surgical catheters in the human body, and these intubation operations rely entirely on the medical staff to hold the catheter and insert it into the surgical incision. This kind of manual work has high requirements for operators, and it is difficult to grasp the stability and accuracy of hand-held intubation; [0003] Publication No. CN106267529B discloses a catheter propeller for cardiovascular surgery. It includes a handle and a runner bin fixedly installed on the upper end of...

AI Technical Summary

Problems solved by technology

It includes a handle and a runner bin fixedly installed on the upper end of the handle. A runner is installed in the runner bin through a bearing, a crank handle is installed on the runner, and a compression nut is inserted in the upper end of the runner bin. The inner end of the compression nut located in the runner compartment is threadedly connected with at least two compression rods, and the at least two compression rods are respectively fixedly connected to the two ends of the compression plate made of elastic material, and the compression wheel is installed on the compression plate; A guide pipe is arranged between the pressure plate and the runner, and the guide pipe is installed on the wall of the runner chamber, and the axis of the guide pipe is located on the tangent line of the runner; the edges of the pressure roller and the runner are provided with matching The arc-shaped ring groove of the surgical intubation, the intubation propeller for cardiovascular surgery is propelled by hand with a rotary wheel, which avoids the defects of instability and poor accuracy caused by manual operation, simple structure, convenient use, and stable operation and the accuracy is greatly improved; however, during the operation, one hand holds the pusher, and the other hand shakes the rocking wheel, and this method causes the force to shake when the wheel is turned, and the two-handed operation There will be certain operational defects, and one-step operation cannot be realized during operation, and the convenience is poor
