Novel pressure-measuring thrombectomy puncture ablation adjustable catheter

Abstract

One end of the catheter is connected with a radiofrequency ablation host, the catheter comprises a supporting device, a puncture device, a pressure measuring device and a measurement and control unit, the supporting device is connected with the puncture device, the pressure measuring device is connected with the supporting device, and the measurement and control unit is communicated with a pipeline of the supporting device. The radiofrequency ablation main machine is electrically connected with the puncture device, the supporting device comprises a handle, a supporting tube, an outer tube and an inner tube, the handle is fixedly connected with one side of the supporting tube, a guide wire cavity is formed in the supporting tube, the outer tube is arranged in the guide wire cavity, a tube hole is formed in the outer tube, the inner tube is arranged in the tube hole, the inner tube and the outer tube are connected in a sealed mode, and the puncture device is communicated with the radiofrequency ablation main machine. Therefore, radiofrequency ablation is carried out, the blood vessel is dredged and treated, and the blood pressure in the blood vessel is detected through the pressure measuring device.

Description

Technical field [0001] The present invention relates to the field of intravenous surgery, in particular a new type of pressure-sensitized tab puncture ablation can regulate the catheter. Background technique [0002] In recent years, with the continuous development of the medical and machinery industry, more and more high-precision instruments have been applied to medical surgery, including the intrahepatic puncture biopsy, intravenous ablation, vascular cavity injection, etc. Conductive wire, through cavity tube, radiofrequency melt pipe, puncture needle, etc. [0003] Hepatic venous pressure gradient detection can reflect the progress of the high pressure of the hepatochased venous venous venous vein, and currently use a double-cavalent bolt balloon catheter to perform pressure, and it is necessary to block local sealing when the pressure is measured, which can cause increasing pressure in the blood vessels. Therefore, During the operation, the patient is required to remain sil...

AI Technical Summary

Problems solved by technology

[0002] In recent years, with the continuous development of the medical and mechanical industries, more and more high-precision instruments have been used in medical operations. Guide wires, thrombectomy catheters, radiofrequency ablation catheters, puncture needles and other instruments require a lot of time to exchange instruments during the operation, which increases the risk of surgery

[0003] Hepatic venous pressure gradient detection can reflect the progress of cirrhotic venous hypertension. At present, a double-lumen embolectomy balloon catheter is commonly used for pressure measurement. During pressure measurement, blood vessels need to be partially blocked, which will lead to increased intravascular pressure. Therefore, During the operation, the patient is required to remain silent and not to cough or sneeze, otherwise the blood vessels will be torn and affect the safety of the operation.

[0004] In addition, when ablation is performed in blood vessels, the ablation temperature cannot be precisely controlled, which may easily cause excessive blood temperature rise, ablation and perforation of blood vessels, and affect the normal operation
