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 relates to a conveying system for conveying an implant and a driving handle. A sheathing canal for conveying the implant can be controlled to move at a high speed or a low speed. The driving handle comprises a shell, a fixing piece, a first driving mechanism and a gear transmission mechanism, the gear transmission mechanism is arranged in the shell, the input section of the gear transmission mechanism is connected with the first driving mechanism, and the output section of the gear transmission mechanism is connected with the fixing piece and used for being driven by the input section to rotate; the first driving mechanism is used for driving the gear transmission mechanism to drive the fixing part to move along the axis of the driving handle, and the gear transmission mechanism is used for outputting multiple transmission ratios and selectively driving the fixing part to move through one of the multiple transmission ratios. The conveying system comprises the driving handle, an outer pipe and an inner pipe assembly. The inner pipe assembly is arranged in the outer pipe in a penetrating manner, is used for fixing the implant and keeps static relative to the shell; theouter pipe is connected with the fixing piece, and the fixing piece is used for driving the outer pipe to axially move relative to the inner pipe assembly.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a delivery system and a driving handle for delivering an implant. 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 ha...
