Problems solved by technology

There are some therapeutic devices in the prior art, such as Figure 17 In the treatment device shown, after the clamping device is closed, it is locked by the friction force of the elastic sheet, but the friction force locking structure is unreliable, and there is a risk of slipping during the heartbeat process. Holding arm opens and clamp loosens, causing clamping device to dislodge from target tissue

Abstract

The invention provides a locking state controllable medical instrument which mainly comprises a mandrel, a main base, an auxiliary base and fool-proof structures. The fool-proof structures are arranged on the main base and the auxiliary base respectively, when the fool-proof structures are in a fool-proof state, mutual locking of a main locking piece and an auxiliary locking piece can be limited, and the clamping distance and the clamping angle between a main clamping piece and an auxiliary clamping piece can be adjusted; when the fool-proof structures are not in a fool-proof state, mutual locking of the main locking piece and the auxiliary locking piece is achieved, and the minimum clamping distance and the minimum clamping angle are formed between the main clamping piece and the auxiliary clamping piece. Therefore, according to the medical instrument, the main locking piece and the auxiliary locking piece can be prevented from being mutually locked in an unexpected state, so that the adjustment operation of the medical instrument is conveniently executed, and the clamping effect of the medical instrument is effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of medical devices, in particular to a medical device with a controllable locking state. Background technique [0002] For pulmonary congestion, pulmonary hypertension, ventricular hypertrophy, atrial hypertrophy, heart failure, systemic circulation congestion and other diseases caused by heart valve insufficiency, traditional treatment methods include active surgical methods. Among them, surgical methods also include valve replacement and valvuloplasty. There are some therapeutic devices in the prior art, such as Figure 17 In the treatment device shown, after the clamping device is closed, it is locked by the friction force of the elastic sheet, but the friction force locking structure is unreliable, and there is a risk of slipping during the heartbeat process. The holding arm is opened, and the clamp is released, causing the clamping device to dislodge from the target tissue. ...
