Deng, for cutting effect, that there are cutting outputs is small for minimally invasive rotation planing tool, is easy to happen chip blocking, and cutting end face is irregular etc.
Problem；For structure, minimally invasive rotation planing tool inner and outer pipes be small diameter long shaft member, tube wall is thin and intensity is insufficient, inner tube turn
Without accurate rotational positioning between axis and outer tube, cause inner tube when driving high speed rotation by dynamical system, plays shear action
Inner tube distal end occur biggish rotation beat amplitude, thus can be sent out with distal outer tube in cutting tooth of the inner tube distally and on distal end
Raw collision, serious influence cutter life, sharpness, cutting stability and safety.
In addition to minimally invasive shaping tool, there are also the Minimally Invasive Surgeries of a series of manual operation to clamp, such as blue pincers, it is minimally invasive cut, olecranon
Pincers etc., but these fine instruments, due to structural weak, intensity is insufficient, and cutting output is very small, and the rotary shaft of distal end is being cut
Stress is easy to happen fracture when cutting, and leads to operative failure and causes to damage to sufferer,
It is then desired to propose a kind of new minimally invasive cutting soft tissue punching movement conversion mechanism.
