Simple-and-convenient-operate papillary muscle auxiliary exposure device

Abstract

The invention discloses a simple-and-convenient-operate papillary muscle auxiliary exposure device. The device comprises a supporting barrel (1); the barrel wall of the supporting barrel (1) is internally provided with a vertical guide groove (2); the waist position of the vertical guide groove in the inner barrel wall of the supporting barrel (1) is provided with a positioning ring groove (3) communicating with the vertical guide groove (2); the vertical guide groove (2) is internally provided with a driving strip (4) capable of sliding in the vertical direction of the vertical guide groove;the positioning ring groove (3) is embedded with an adjusting ring (5) capable of rotating around the central axis of the supporting barrel (1); the outer wall of the adjusting ring (5) is in contactwith and in threaded fit connection with one side wall of the driving strip (4); the bottom end of the driving strip (4) is further provided with a connecting block (6); the connecting block (6) penetrates through an avoiding groove (7) formed in the barrel wall of the supporting barrel (1) to be connected with the top end of an elastic strip (8); and the bottom end of the elastic strip (8) is fixedly arranged on the barrel wall of the supporting barrel (1). The device has the characteristics of convenient operation, flexible use and high safety.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an easy-to-operate auxiliary papillary muscle exposure device. Background technique [0002] Mitral valve repair is an effective way to treat mitral valve disease. Compared with mitral valve replacement, mitral valve repair retains its own valve leaflets, which not only avoids the risks of anticoagulation complications and valve failure caused by valve replacement, Moreover, good hemodynamics of the valve are preserved. Mitral valve repair techniques are complex and changeable, and the appropriate repair technique is mainly based on the mechanism that causes mitral valve regurgitation. Artificial chord implantation is the best way to repair mitral valve regurgitation caused by rupture of mitral valve chord or redundant chord. In the process of implanting the artificial chordae, the artificial chordae must be precisely positioned on the papillary muscle corresponding to the ruptur...

AI Technical Summary

Problems solved by technology

Since these instruments are not special-purpose instruments, it is cumbersome and difficult to operate when separating the valve leaflets, which makes the operation of chordal implantation difficult, inaccurate positioning, prolonged operation time, and poor surgical effect; in addition, inappropriate violent traction Not only will it damage the mitral valve leaflets, but it also has the risk of damaging the left ventricular myocardium and causing serious complications such as heart rupture
