Problems solved by technology

However, the traditional handle cannot adjust the speed of advancing and retreating of the sheath when releasing and recovering the valve, making it difficult for the operator to control the implantation speed and position of the valve, resulting in large positioning errors and low surgical efficiency

Abstract

The invention provides a driving handle and a conveying system for conveying an implant. The driving handle can drive an outer tube which is used for conveying the implant to perform variable motion,namely, the handle controls motion of the outer tube at different speeds according to requirements of actual operation, thereby improving operation efficiency and reducing operation difficulty. The driving handle specifically comprises a hand-held sleeve, a fixed sleeve, a first driving mechanism, a second driving mechanism and a transmission mechanism; at least one part of the fixed sleeve movably penetrates through the hand-held sleeve; the first driving mechanism, the second driving mechanism and the transmission mechanism are all movably arranged on the hand-held sleeve; the first drivingmechanism is connected with the fixed sleeve, and is configured to directly drive the fixed sleeve to move along the axis of the driving handle at a first speed under action of external force; the second driving mechanism is configured to push the transmission mechanism under action of external force; and the transmission mechanism drives the first driving mechanism and the fixed sleeve to synchronously move along the axis of the driving handle at a second speed, wherein the second speed is not equal to the first speed.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a driving handle and a delivery system for delivering implants. Background technique [0002] With the development of social economy and the aging of the population, the incidence of valvular heart disease has increased significantly. Studies have shown that the incidence of valvular heart disease in the elderly population over 75 years old is as high as 13.3%. At present, traditional surgical treatment is still the first choice for patients with severe valvular disease, but for patients who are elderly, complicated with multiple organ diseases, have a history of thoracotomy, and have poor heart function, the risk of traditional surgery is high and death The rate is high, and some patients do not even have the chance of surgery. [0003] Transcatheter heart valve surgery has the advantages of no need for thoracotomy, less trauma, and faster recovery of patients, and has ...
