Intubation tube device for cardiovascular surgery

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to an intubation tube device for cardiovascular surgery. The intubation tube device comprises a shell, a left guiding tube and a right guiding tube are fixedly connected to the left side wall and the right side wall at the upper portion of the shell respectively, a sliding groove is formed in the left side wall of the shell, a ratchet wheel is arranged in the center of the top end inside the shell, a pawl is arranged inside the ratchet wheel, a driven gear is fixedly connected to the top end of the plane of the ratchet wheel, a driving gear is arranged at the lower right portion of the driven gear, the driving gear is meshed with the driven gear, a third rotating shaft is fixedly arranged atthe upper right portion of the inner side of the shell, a rack is fixedly connected to the lower left end of a pressing block, and is meshed with the driving gear, an intubation tube is arranged at the top end of the ratchet wheel, and runs through the right guiding pipe and the left guiding pipe, a pressing plate is arranged above the intubation tube, and multiple auxiliary rotating wheels are arranged in the pressing plate. According to the intubation tube device for the cardiovascular surgery, it can be achieved that the intubation tube is evenly and stably intubated through holding of onehand, and the intubation tube device is simple and scientific, has wide market requirements, and is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an intubation device for cardiovascular surgery. Background technique [0002] Vascular intubation is an operation that must be performed in cardiovascular surgery. It is a technique that inserts catheters from peripheral blood vessels and sends them to the heart cavity and large blood vessels to obtain information and perform treatment. It is generally divided into left heart Catheter surgery and right heart catheterization, heart catheterization is a very complicated operation. During cardiovascular surgery, it is often necessary to insert a surgical catheter into the human body. Insertion, this kind of manual work has high requirements for operators, and it is difficult to grasp the stability and accuracy of hand-held intubation. Therefore, the demand for intubation devices for cardiovascular surgery is increasing day by day. [0003] The current cardiovascular in...

[0002] Vascular intubation is an operation that must be performed in cardiovascular surgery. It is a technique that inserts catheters from peripheral blood vessels and sends them to the heart cavity and large blood vessels to obtain information and perform treatment. It is generally divided into left heart Catheter surgery and right heart catheterization, heart catheterization is a very complicated operation. During cardiovascular surgery, it is often necessary to insert a surgical catheter into the human body. Insertion, this kind of manual work has high requirements for operators, and it is difficult to grasp the stability and accuracy of hand-held intubation. Therefore, the demand for intubation devices for cardiovascular surgery is increasing

[0003] The current cardiovascular intubation is generally performed by hand-held fixing frame and intubation forceps, which requires the assistance of multiple people. Although the intubation forceps can improve the accuracy and stability of the intubation operation to a certain extent, it can only be used to fix the intubation. The intubation and easy-to-handle functions cannot realize the action of pushing the intubation. During the intubation operation, the operator still relies on the operator to move the arm to achieve the operation of the intubation. For the inexperienced and unskilled doctors, accurate and stable movement during the operation The arm is very difficult, therefore, a catheterization device for cardiovascular surgery is proposed to address the above problems
