Instrument placing rack for atrial fibrillation cryoablation operation in cardiac surgery

Abstract

The invention relates to the technical field of medical auxiliary instruments, in particular to an instrument placement rack for cardiac surgery atrial fibrillation cryoablation surgery, which comprises a cryoablation instrument, a placement support is fixedly connected to one side of the cryoablation instrument, and universal wheels are connected to the bottoms of the cryoablation instrument and the placement support. A Dewar flask is connected in the placing support through a positioning mechanism, a high-pressure metal hose is fixedly connected to a use valve of the Dewar flask, and one end of the high-pressure metal hose is fixedly connected to a liquid inlet of the cryoablation instrument; according to the technical scheme, the flowing speed and flow of flowing-out freezing media are controlled by operating the cryoablation instrument, so that the dosage accuracy during treatment of a patient is improved, the overlong part of the liquid outlet catheter is wound through the winding and unwinding mechanism, medical workers are prevented from stepping on the liquid outlet catheter in the operation process, and the medical workers are prevented from being damaged. The freezing medium can normally flow out of the liquid outlet catheter, and the liquid outlet stability of the freezing medium in the operation process is improved.

Description

technical field [0001] The invention relates to the field of medical auxiliary instruments, in particular to an instrument placement rack for atrial fibrillation cryoablation in cardiac surgery. Background technique [0002] Cryoablation is a surgical technique that uses freezing to eliminate target tissue. Cryoablation is a new technology for the treatment of arrhythmia invented by researchers after radiofrequency ablation. The temperature of the target ablation site is lowered, and abnormal electrophysiological cell tissues are destroyed, thereby reducing the risk of arrhythmia. [0003] The establishment of truly "modern" cryosurgery began in the late 1990s, mainly due to advances in two areas: imaging technology and new cryogenic equipment. Due to the wide application of ultrasound and CT, under the monitoring and guidance of imaging technology, the cold probe can be inserted accurately, the process of freezing can be observed in real time, and the freezing range can be...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, in the process of surgery, the surgical instruments are placed centrally by placing the surgical instrument racks in the operating room so that the surgeon can take them conveniently. Ultra-low temperature freezing is performed on the affected area. During surgery, the cryoablation tubes that deliver the freezing medium are usually scattered on the ground, which hinders normal walking. If the medical staff step on the cryoablation tube during the operation, it will hinder the delivery of the freezing medium and affect the surgical effect. , and the cryoablation tube is not convenient for positioning and support during the transportation process. When it is pulled for no reason, it is easy to cause the part where the end of the cryoablation tube is in contact with the human body to be torn apart, affecting normal use
