For solving the problem, the technical solution adopted in the present invention is as follows:
A kind of intervertebral disk prosthesis shock-absorbing type ball pad, the joint pin comprising hemisphere and be connected with hemisphere, described hemisphere sphere is provided with dashpot.
Preferably, the width H of described dashpot is 1/4 to 3/4 of horizontal cross-section, dashpot place circular diameter D.
Preferably, the centrage in described dashpot width H direction and the hemisphere centre of sphere are 0-4mm in horizontal cross-section, dashpot place inner projection distance.
Preferably, the centrage in described dashpot width H direction and the hemisphere centre of sphere are 0mm in horizontal cross-section, dashpot place inner projection distance.
Preferably, two circumferentially clockwise adjacent dashpots, the angle α between the centrage in its width H direction projects in the horizontal plane, α is 2-90 °.
Preferably, described dashpot bottom land is fillet.
Preferably, the through sphere of described dashpot horizontal direction, dashpot is arranged on hemisphere varying level cross section.
Preferably, described dashpot quantity is even number, and is at least 2.
Preferably, the distance L that the described dashpot degree of depth extends beyond hemisphere axis equals 1/8 to 1/4 of horizontal cross-section, dashpot place radius of circle.
Preferably, described dashpot bottom land is fillet.
Compared to existing technology, beneficial effect of the present invention is:
1, intervertebral disk prosthesis shock-absorbing type ball pad in the present invention, it can make intervertebral disk prosthesis have significant damping effect, the shock loading produced when relaxing human motion, the injury brought that protection human body buffering is not enough;
2, in the present invention, the degree of depth of dashpot and the position of adjacent buffer groove are arranged, and meet while rationally bending, can reach best buffering effect;
3, intervertebral disk prosthesis shock-damping structure structure of the present invention is simple, with low cost, and has better bradyseism effect, can reduce the medical treatment cost of patient further.
