Problems solved by technology

[0003] At present, scissors and tonsil forceps are usually used to mechanically separate calcified plaques, which can easily cause calcified plaques to fall off, unclear tissue layers, unnecessary side damage, etc., resulting in residual plaques in the heart cavity, embolism of distant organs, and even failure. The tissue of the annulus is preserved intact, resulting in poor fit of the annuloplasty ring and the suture of the artificial valve, causing paravalvular leakage

Abstract

The invention discloses a containing type ultrasonic scalpel which comprises a control device, a conduction structure, a holding structure, a filtering device, a power source structure and a vibration structure. The conduction structure comprises a wire, a gas-guide tube and a conduction shell; the wire and the air guide pipe are arranged in the conduction shell. One end of the conduction shell is detachably connected with the control device, and the other end of the conduction shell is detachably connected with the holding structure; the end, away from the conduction structure, of the holding structure is detachably connected with the filtering device. The end, away from the holding structure, of the filtering device is detachably connected with the vibration structure. The vibration structure is arranged in the filtering device; the power source structure is arranged on the outer wall of the control device and fixedly connected with the control device.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an accommodation type ultrasonic scalpel. Background technique [0002] Calcification of heart valves is a natural aging process, and is more common in degenerative changes in the elderly. Calcification caused by external injury or infection and inflammatory response is rare, so the calcification of the heart valve cannot be dealt with in terms of calcification itself, but if the calcification of the heart valve leads to pathological changes in the valve, such as valve insufficiency Causes regurgitation, or the stenosis of the valve causes the obstruction of blood flow, and at this time, it needs to be dealt with accordingly. [0003] At present, scissors and tonsil forceps are usually used to separate calcified plaques mechanically, which is easy to cause calcified plaques to fall off, unclear tissue levels, unnecessary secondary injuries, etc. The tissue o...
