Cardiovascular surgery intubation propeller for department of cardiology

Abstract

The invention discloses a cardiovascular surgery intubation propeller for department of cardiology, which relates to the technical field of medical instruments, and comprises a support plate, an upperextrusion wheel and a lower extrusion wheel are respectively arranged on the upper side and the lower side of the right side wall of the support plate, and a tooth groove is formed in the circumferential surface of the right side edge of the upper extrusion wheel. According to the cardiovascular surgery intubation propeller for the department of cardiology, an intubation tube can be clamped through mutual cooperation of the arranged upper extrusion wheel capable of ascending or descending and the fixed lower extrusion wheel, and the intubation tube can be in an S shape when passing through the space between the upper extrusion wheel and the lower extrusion wheel through sliding of the arranged intubation tube in the two limiting sleeves, and then increasing the contact area between the intubation tube and the upper extrusion wheel and the lower extrusion wheel, through the meshing of arranged teeth and tooth grooves, when the lower extrusion wheel rotates, the upper extrusion wheel can synchronously rotate, then the upper extrusion wheel and the lower extrusion wheel can push the intubation tube to move towards the front side together, and the stability of pushing the intubation tube can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intubation propeller for cardiac surgery and cardiovascular surgery. Background technique [0002] The intubation pusher is a device for inserting a medical catheter into the human body during a surgical operation. This device can improve the accuracy and stability of the intubation operation to a certain extent. [0003] In cardiovascular surgery, it is often necessary to insert surgical catheters into the human body. These intubation operations rely entirely on medical staff to insert the cannula into the surgical incision. This manual operation has high requirements for operators, and the stability and The accuracy is difficult to grasp, and in the prior art, the intubation propeller for cardiovascular surgery generally drives the intubation forward through the rotation of a single push wheel. The stability of propulsion cannot be guaranteed, and phenomena such as ...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an intubation propeller for cardiac surgery and cardiovascular surgery, which solves the problem that in the prior art, the intubation propeller for cardiovascular surgery drives the intubation forward through the rotation of a single push wheel, and the intubation and a single If the contact area between the push wheels is too small, the stability of the intubation cannot be guaranteed, and problems such as slipping may occur
