Bending control handle for conveying implant and conveying system thereof

Abstract

The invention discloses a bending control handle for conveying an implant and a conveying system thereof. The handle comprises a box body (12), a driving shaft (2), a driving gear (3), a bending control pipe (13) and a bending control line (11), wherein the bending control pipe (13) and the bending control line (11) are connected with the box body; the driving gear (3) is connected to the driving shaft (2), more than two driven racks (4) are arranged in the box body, and the driving gear (3) can be respectively meshed with each driven rack (4) through switching; each driven rack (4) is provided with a bending control line (11), and the bending control line (11) is connected with the bending control pipe (13) and used for controlling bending of the bending control pipe (13). All bending control directions are integrated through one knob, so that the handle can be lightened and simplified, and the surgical operation is more efficient and simpler.

Description

technical field [0001] The invention relates to a bending control handle for delivering implants and a delivery system thereof. Background technique [0002] According to surveys, the probability of middle-aged and elderly people suffering from heart valve disease is increasing year by year, which will 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 continuous exploration in the world, and has become the most promising branch in the field of interventional therapy. [0003] Interventional therapy is a br...

Problems solved by technology

like Figure 7 , even if the bending control wire 11 passes through the fixed shaft 101 at a suitable position, after the bending control wire 11 is wound on the fixed shaft 101 for a certain number of turns, there will still be a large contact friction between the bending control wire 11 and the fixed shaft 101 resistance, preventing further rotation of the rotating member 102, making it difficult to further tighten the bending control line 11, and the effect of bending control becomes worse
