Medical handle, medical conveying device and myocardial anchoring system

Abstract

The invention provides a medical handle, a medical conveying device and a myocardial anchoring system. The stability and safety of myocardial anchoring can be guaranteed, the operation skill of a doctor is improved, and the operation time is shortened. The medical handle comprises a pipe fitting, a sensor and an operation handle; the far end of the pipe fitting is used for being in abutting connection with an external component; the operation handle is connected with the pipe fitting; and the sensor is connected with the pipe fitting and used for sensing contact force borne by the external component. The medical conveying device comprises a conveying catheter and the medical handle, the conveying catheter is used for loading the external component, and the pipe fitting is used for being movably inserted into the conveying catheter and pushing the external component to move. The myocardial anchoring system comprises a myocardial anchoring device and the medical conveying device, the myocardial anchoring device comprises the external component, the external component comprises an internal anchoring part, an external anchoring part and a tightening mechanism, the conveying catheter isused for loading the tightening mechanism and / or the internal anchoring part and the external anchoring part, the pipe fitting is used for allowing the tightening mechanism to penetrate and being inabutting connection with the external anchoring part, and the sensor is used for sensing contact force borne by the external anchoring part.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical handle, a medical delivery device and a myocardial anchoring system. Background technique [0002] Heart failure is the terminal stage of most cardiovascular diseases. Although the application of heart failure drugs in the past 20 years has obviously benefited heart failure patients, the mortality rate of end-stage heart failure patients is still high. The pathophysiological basis of heart failure is cardiac remodeling. Cardiac remodeling, manifested clinically by progressive ventricular dilation and impaired systolic and diastolic function, is associated with progressive heart failure and increased mortality. Angiotensin-converting enzyme inhibitors (ACEI) / angiotensin II receptor antagonists, beta-blockers, aldosterone receptor antagonists, and cardiac resynchronization therapy (CRT) recommended by current guidelines can slow down or reverse The remodeling o...

Problems solved by technology

[0005] However, the existing myocardial anchoring devices are not conducive to the doctor's operation, time-consuming and labor-intensive, and there is no force feedback mechanism. Whether the anchoring is in place depends only on the doctor's experience. If the anchoring force of the device exceeds the requirements, it will cause tissue perforation, etc. potential risks
