Handle, catheter assembly and delivery system for delivering implants

Abstract

The invention discloses a handle, a catheter assembly and a delivery system for delivering implants. The handle comprises a handle shell, a driving component and a transmission component; a first connecting part is arranged at a near end of the handle shell; the driving component is used for controlling the transmission component to axially move relative to the handle shell, a second connecting component is arranged at a far end of the transmission component, and the handle is detachably connected with a catheter assembly through the first connecting component and the second connecting component. According to the invention, the catheter assembly is inserted into the handle, a near end of the handle is detachably connected with a near end of the catheter assembly, the transmission component in the handle is detachably connected with an outer tube base, meanwhile, a sectional size of the handle can be reduced, and rapid withdrawing of an inner tube assembly can be achieved. If the handle breaks down in an operation process, the handle can be rapidly detached and replaced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a handle for delivering implants, a catheter assembly and a delivery system. Background technique [0002] According to surveys, the chances of middle-aged and elderly people suffering from coronary heart disease, cardiovascular and cerebrovascular diseases, heart valve diseases, tumors and other diseases are increasing year by year. These diseases directly affect the quality of life and even life safety of middle-aged and elderly people. Traditional surgical treatment is still the first choice for seriously ill patients. However, for patients who are elderly, complicated with multiple organ diseases, have a history of open chest surgery, and have poor physical recovery function, traditional surgery has high risks and high mortality. Patients do not even have the chance of surgery. In the past ten years, interventional therapy has made significant progress through conti...

Problems solved by technology

On the one hand, there is a risk of failure of the handle during the operation. If the existing handle has a safety failure, the only option is to convert the interventional operation to a surgical operation urgently, which will bring greater physical trauma to the patient and even threaten life; On the other hand, the handle contains many parts, and the handles currently on the market cannot be reused, so the cost is high, the corresponding operation cost is high, and the patient's economic pressure is relatively high.
