A kind of interposing catheter of controlled deflectionTechnical field
This utility model relates to a kind of interposing catheter, particularly relates to a kind of interposing catheter of controlled deflection.
Background technology
Minimally invasive surgical techniques is risen the eighties in 20th century, and intervene operation is its important branch.People's Jie operation can be divided into blood vessel to get involved and Non-vascularized iliac bone operation.At present, apply Medical Robot clinically and can carry out multiple operation, mainly contain laparoscopic surgery and the stereotactic surgery at field of neurosurgery, and the research of Medical Robot's application in intravascular intervention operation is just just started.The harsh environments that intravascular intervention robot can make doctor break away from heavy dose of x-ray bombardment lower body to be endangered, also can alleviate the operation easier of doctor.Develop the urgent needs that intravascular intervention robot has become era development.The research of intravascular intervention robot is divided into controlled deflection interposing catheter and master & slave control intervention device (i.e. servo manipulator) two parts.
One of research and development key of the interposing catheter of controlled deflection is the research and development in controlled joint.The controlled joint of controlled deflection interposing catheter is researched and developed requirement and is: have bending, swing movable function on a large scale in level with longitudinal, the manipulation wish of manipulator can be responded rapidly, use less power just can reach the object of manipulation arthrogryposis, diameter runs business into particular one the object adapting to enter blood vessel at different levels as far as possible.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of interposing catheter of controlled deflection, realizes interposing catheter in Ink vessel transfusing bending and swing activity on a large scale, facilitates interposing catheter in endovascular operation.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of interposing catheter of controlled deflection, comprises the first conduit, the second conduit, bending conduit;
Described bending conduit is double-decker, and skin is smooth layer, and internal layer is plicated layer, and it comprises angle controller, wire, control unit, and described angle controller is connected with control unit by wire;
Described second conduit is double-decker, and described first conduit is connected by bending conduit with the second conduit, and bending conduit degree of crook is adjustable.
Further, described angle controller, wire and control unit are arranged between smooth layer and plicated layer.
Further, described smooth layer adopts transparent material to make.
The beneficial effects of the utility model are: technique is simple, and production efficiency is high, can the degree of crook of regulating and controlling bending conduit better, improve carrying out smoothly of the convenient degree of operation and intervene operation.

Detailed description of the invention
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining this utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, a kind of interposing catheter of controlled deflection, comprises the first conduit, the second conduit, bending conduit;
Described bending conduit is double-decker, and skin is smooth layer, and internal layer is plicated layer, and it comprises angle controller, wire, control unit, and described angle controller is connected with control unit by wire;
Described second conduit is double-decker, and described first conduit is connected by bending conduit with the second conduit, and bending conduit degree of crook is adjustable.
Further, described angle controller, wire and control unit are arranged between smooth layer and plicated layer.
Further, described smooth layer adopts transparent material to make.
The interposing catheter of controlled deflection of the present utility model, by controlling described control unit control angle controller, described angle controller regulates plicated layer in various degree bending, realizes the differently curved of interposing catheter.
Compared with prior art, the utility model has the advantage of, technique is simple, and production efficiency is high, can the degree of crook of regulating and controlling bending conduit better, improves carrying out smoothly of the convenient degree of operation and intervene operation.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
