Cardiac surgery extracorporeal circulation pipeline fixing device and using method

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to a cardiac surgery extracorporeal circulation pipeline fixing device and a using method, the cardiac surgery extracorporeal circulation pipeline fixing device comprises a pipeline fixing assembly and a mounting assembly, and the pipeline fixing assembly is arranged at the top of the mounting assembly; the pipeline fixing assembly comprises a pipeline fixing plate, a pipeline fixing hole is formed in the front surface of the pipeline fixing plate, a hinge is arranged on one side of the top of the pipeline fixing plate, a cover plate is arranged on the hinge, and a locking spring pin is arranged at the bottom of one side of the cover plate. A locking pin hole matched with the pipeline fixing plate is formed in one side of the pipeline fixing plate, and a connecting bolt is arranged at the bottom of the pipeline fixing plate; the mounting assembly comprises a clamping sleeve, a connecting insertion hole matched with the connecting plug pin is formed in the top of the clamping sleeve, the device is reasonable in structure, time and labor are saved when an extracorporeal circulation pipeline is fixed in a heart operation, and the pipeline is more convenient to adjust in the operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cardiac surgery extracorporeal circulation pipeline fixing device and a use method. Background technique [0002] Extracorporeal circulation is a life support technology that uses a series of special artificial devices to drain human venous blood to the outside of the body. In the process of extracorporeal circulation, because the artificial device replaces the function of the human body, it is also called cardiopulmonary bypass, and the extracorporeal circulation machine is also called artificial heart-lung machine. [0003] Cardiac surgery requires the assistance of extracorporeal circulation when correcting the heart or / and large vascular malformations. The extracorporeal circulation has multiple pipelines with different functions, which are all important connecting pipelines and hubs connecting the patient's own arterial and venous blood with the artificial heart an...

Problems solved by technology

[0006] 1. Time-consuming

2. After the sterile gauze is bound and fixed, the pipeline is still movable, and the fixation is not firm

3. It is troublesome to adjust the length of the pipeline on the operating table

4. A piece of sterile gauze needs to be used, which may occasionally cause confusion in the counting of gauze on the instrument nurse's table, affecting the quality and progress of the operation

At present, there are no ideal special instruments and clips for fixing the extracorporeal circulation pipeline. Most clinically, sterile gauze is used to wrap the pipeline and fix it on the surgical towel with cloth forceps. There are also improvements to the extracorporeal drape for fixing the pipeline. Occasionally, merchants design open Type fixing clips are not widely used due to various defects or deficiencies such as cumbersome operation, difficulty in adjusting the length of the pipeline, and resistance to external pressure. Therefore, we propose a new type of fixing device for extracorporeal circulation pipeline and its use method to solve the above problems
