Abstract

The invention relates to a valve conveying device which comprises a bending adjusting pipe, a withdrawing assembly, a traction wire, a bending adjusting rotating wheel and a stabilizing pipe, the withdrawing assembly is connected with the bending adjusting pipe, the bending adjusting rotating wheel is provided with a traction block, one end of the traction wire is connected with the withdrawing assembly, and the other end of the traction wire is connected with the traction block. The bending adjusting pipe is sleeved with the stabilizing pipe, the stabilizing pipe is arranged between the withdrawing assembly and the bending adjusting rotating wheel, the bending adjusting rotating wheel is used for adjusting the position of the traction block, and the traction block drives the withdrawing assembly to move through the traction wire to adjust the bending degree of the bending adjusting pipe. And the stabilizing pipe is used for limiting the bending position of the bending adjuster, so that the control precision of the bending form of the valve conveying device is improved.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a valve delivery device. Background technique [0002] With the continuous improvement of science and technology, the emergence of artificial valves has solved many medical problems, such as the use of implantable artificial heart valves to implant the heart instead of heart valves to treat heart disease, etc. The implantation of heart valves is inseparable from valve delivery The valve delivery device delivers the valve from the body through the blood vessel to the designated position and releases it. However, due to the complex structure of the physiological valve, there is an angular deviation between the approach and the valve axis during valve intervention, which requires the valve delivery device. It has a certain ability to adjust the angle, so that the valve is coaxial with the native valve during the release process, and the stability and accuracy ...
