Valve forming ring adjusting device and forming ring thereof

Abstract

The invention discloses a valve forming ring adjusting device and a forming ring thereof, a strip-type plate is arranged on an adjusting part I longitudinally, at least two clamping lugs are arrangedon one plate surface I of the strip-type plate longitudinally in parallel, a clamping part is arranged on an adjusting part II, the clamping part can be in clamping fit with different clamping groovesfrom an initial position to the maximum position so as to adjust the size of the valve forming ring, and the clamping part can return to the initial position after in the maximum position; the adjusting device is simple in structure and easy to operate, less components are adopted, the matching and processing difficulty of the components is small, the manufacturing process is simple, the device cost is low, and the device has higher reliability during the use; the adjusting device is used for the forming ring, the size of the forming ring can be adjusted as required in the operation process,the operation problem caused due to the fact that the size of the forming ring cannot be adjusted is avoided, and the adjusting device is simple in structure and portable so that the adjustment operation of the whole forming ring is simple and convenient and the device is easy to control.

Description

technical field [0001] The invention relates to an instrument for heart valve forming operation, in particular to a valve forming ring adjusting device and the forming ring. Background technique [0002] The valvuloplasty ring is a medical device formed by valvuloplasty for heart valve insufficiency. The use of valvuloplasty ring for surgery not only restores the closing function of the native valve to obtain good hemodynamic effects, but also has a short postoperative anticoagulant period, low operative mortality and recurrence rate. But the size of the forming ring is required, otherwise, valvuloplasty or valve replacement often needs to be performed again, which not only increases the economic burden, but also causes greater pain to the patient. In order to solve the above problems, the patent document with the application number 201710038066.3 discloses an adjustable heart valvuloplasty device, which uses a regulator to adjust the size of the valvuloplasty ring, which c...

AI Technical Summary

Problems solved by technology

[0003] Although the aforementioned adjustable heart valve forming device can adjust the size of the forming ring, the structure is relatively complicated, involving many parts, and the matching and processing are difficult, so the manufacturing process is complicated, resulting in high cost. Due to the structure The complexity leads to reliability and also has certain problems
