Description
Technical field
The present invention relates to theory of mechanisms, and in particular to a kind of space apocenter fitness machine using Double-stroke arc-shaped slide rail
Structure.
Background technique
The characteristics of apocenter movement mechanism be mechanism output link can in space certain fixed point rotation and along
The axis for crossing the fixed point is mobile, however there is no actual kinematic pairs to exist in this fixed point.Apocenter movement mechanism is big
It applies in welding and Minimally Invasive Surgery field, the operator in these fields needs that there is skilled operating technology can just complete more
Operation task.And these fields can be substantially reduced to the technical requirements of operator using apocenter movement mechanism.
By taking Minimally Invasive Surgery as an example, surgical instrument is protruded into disposition position by the small notch of patient body-surface and performed the operation by doctor
Operation, common Minimally Invasive Surgery need to cut the notch of 3 to 4 diameters about 1cm in patient body-surface, and one of notch is used to be inserted into
Endoscope, so that doctor sees the situation inside notch clearly, other notch, which are used to be inserted into surgical instrument, makes doctor remove, suture
Equal surgical procedures.Minimally Invasive Surgery traditional at present requires doctor to hold surgical instrument, carries out lever fortune by fulcrum of operative incision
It is dynamic, this process can enable the surgical clamp of surgical instrument front end movement and doctor's hand movement completely on the contrary, behaviour to doctor
Make and physical fitness requirement is very stringent.On the other hand with universal, the above-mentioned manual operation medical treatment of automedica robot system
Instrument will be replaced by robot system, and apocenter movement mechanism is the core of this medical robot executing agency
Part.
Summary of the invention
The present invention needs doctor to have skilled operating technology to solve in Minimally Invasive Surgery, not knack
Doctor is difficult to perform the operation, and working efficiency is low, and the operating time is long, and accuracy is low, and long-term surgery needs doctor good when carrying out
Physical strength, and then propose a kind of space apocenter movement mechanism using Double-stroke arc-shaped slide rail.
The technical solution adopted by the present invention to solve the technical problems is: a kind of space using Double-stroke arc-shaped slide rail
Apocenter movement mechanism, it is characterised in that: the space apocenter movement mechanism using Double-stroke arc-shaped slide rail includes branch
Frame 1, vertical rotating shaft mechanism 2, vertical rotation frame mechanism 3, fixed sliding block 4, Double-stroke arc-shaped slide rail 5, movable slider 6 and straight line fortune
Motivation structure 7；The upper end of the vertical rotating shaft mechanism 2 is fixedly connected with 1 upper end extension of bracket, and vertical rotating shaft mechanism 2 rotates defeated
Outlet and vertical rotation frame mechanism 3 are rotatablely connected；Vertical rotation frame mechanism 3 is fixedly connected with fixed 4 one sides of sliding block；It is fixed
Another side of sliding block 4 and a side of Double-stroke arc-shaped slide rail 5 are slidably connected；Double-stroke arc-shaped slide rail 5 it is another
One side is slidably connected with 6 one sides of movable slider；Another side of movable slider 6 is fixedly connected with straight-line motion mechanism 7.
The present invention has the effect that by taking Minimally Invasive Surgery as an example that doctor is small by patient body-surface compared with prior art
Surgical instrument is protruded into disposition position and is operated by notch, and when operation, endoscope is inserted into operative incision by doctor, with notch
Lever motion, that is, apocenter movement is carried out for fulcrum, the movement of doctor's hand and the movement of endoscope lens are just the opposite.It uses
The present invention can save time cost, improve working efficiency, easy to operate to be easy to operate, and can allow the doctor of not no knack
Implement Minimally Invasive Surgery through the invention；The doctor with knack can be allowed easy to operate, improve working efficiency, improve operation
Accuracy shortens operating time.
