It is understood that the multiple degree of freedom motion 1112 may control the interventional instrument 112 to produce at least two of rotation, translation, oscillation, and the like. Specific structure for the multiple degree of freedom mover 1112 is mentioned below. The clamping member 1113 is used to clamp the interventional device 112, so that the interventional device 112 is reliably installed in the position and posture adjusting assembly 111, and the interventional device 112 is prevented from falling off during the operation. The multi-degree-of-freedom movement member 1112 is movably attached to the mounting member 1111 at one end and movably attached to the holding member 1113 at the other end. In this way, multi-degree-of-freedom motion element 1112 can move relative to mounting element 1111 to move clamping element 1113 and interventional instrument 112 therein.

It is understood that the rotating member 11121 is rotatably mounted to the mounting member 1111 and the rotating member 11122 is rotatably mounted to the rotating member 11121; the rotating member 11122 may be rotatably attached to the mounting member 1111 and the rotating member 11121 may be rotatably attached to the rotating member 11122. Furthermore, the number of the rotating member 11121 and the rotating member 11122 is one or more, the rotating member 11121 includes but is not limited to a rotating link, and the rotating member 11122 includes but is not limited to a rotating link. Optionally, the rotating members 11121 and the rotating members 11122 have driving capability to drive the rotating members 11121 and the rotating members 11122 to move. Furthermore, the driving capability is realized by a motor, an air cylinder, a hydraulic cylinder or piezoelectric ceramics.

The pushing member 11123 is mounted to the end of the rotating member 11122 or the rotating member 11121 on which the holding member 1113 is movably mounted. The pusher 11123 is used to effect pushing of the interventional instrument 112 such that the interventional instrument 112 penetrates a focal region of the patient 300.

Then, the pushing member 11123 pushes the holding member 1113 to move the interventional device 112 linearly along the interventional angle, so that the interventional device 112 penetrates into the lesion area of the patient 300. Alternatively, the pusher 11123 includes a housing and a linearly moving member disposed in the housing, and the clamp 1113 is located in the housing and mounted to an end of the linearly moving member. When the linear motion part moves, the clamping part 1113 can be pushed to drive the interventional device 112 to move. Further, the linear motion member includes, but is not limited to, a linear motor, a hydraulic cylinder, an air cylinder, or other components capable of outputting linear motion.

Of course, the pushing member 11123 can also be a component of the telecentric fixed point function currently used in surgery, and the pushing member 11123 can ensure that the position and posture of the interventional device 112 are fixed after the rotating member 11121 and the rotating member 11122 ensure the interventional angle of the interventional device 112. Subsequently, the pusher member 11123 may provide rotational and push control of the interventional instrument 112 so that the interventional instrument 112 may be accurately inserted into the lesion of the patient 300. The parts with the telecentric fixed point function form a stable supporting mechanism by a plurality of connecting rods, which is the prior art and is not described in detail herein. And the pushing piece 11123 has driving capability to realize the driving of the pushing piece movement. Furthermore, the driving capability is realized by a motor, an air cylinder, a hydraulic cylinder or piezoelectric ceramics.

In this case, the mounting member 1111 may be directly mounted to the mobile box or the ground. Thus, movement of the two horizontal links causes the rotation member 11122, the swing link, and the pushing member 11123 to extend, such that the interventional instrument 112 moves over the focal region. The rotation of the rotating member 11122 and the swinging of the swinging link can drive the pushing member 11123 and the interventional device 112 therein to move so as to adjust the posture of the interventional device 112, so that the interventional device 112 is located above the lesion area at an accurate interventional angle.
