#Motor (31) promotes gear (17) and sleeve (10), makes puncture needle finish the simulation staff and comes and goes and twist, and cutting ring bar (6) and puncture needle (2) are twisted synchronously, cuts the tough and tensile fibrous ring in perforated space ground with the blade of its end face.Under X-ray video monitor guides, after the cutting ring head passes through fibrous ring, start 3
#Motor (12), by shaft coupling (13) screw mandrel (15), driving lever (14) and cutting ring fixed axis (8) make the rotation of cutting ring bar (6) synchronous backward, but stop feed.And puncture (2) move on, and makes cutting and scrape that window (3) exposes gradually and be close with vertebral pulp thereafter, when cut scrape window (3) and all enter cutting region after, even 1
#Motor (25) stall.Start 4 simultaneously
#Motor (30), driven wheel (20), axis (11), drive spiral planing tool (5) fast rotational, and start negative pressure device simultaneously.Make to suck and cut the nucleus pulposus of scraping window (3) and cut and be twisted into chip, by the gap a between the bar portion outer wall of puncture needle (2) inwall and spiral planing tool (5), sulculus b on the axis (11) and the annular distance (22) on the inserting needle frame (24) by in the negative pressure suction crumb loading bottle.When cutting finishes, stop negative pressure-pumping, start 1
#The motor reverse rotation, the while 3
#The rotation that direction was opposite, revolution is identical when motor was also done with inserting needle, window (3) can all be retracted in the cutting ring bar (6) like this.At this moment, stop 3
#Motor starts 2
#Motor, needle tubing withdraws from while twisting with the fingers, and also can not twist, and directly withdraws from, and treats that puncture needle (2) all returns needle outlet (1) and can shut down, and treatment finishes.
Compare with background technology, the utlity model has following beneficial effect:
1, the operator is away from the scene, and straighforward operation does not need to change nook closing member, treatment time is short, Avoided the impact of radio radiation.
2, all the time can be in the lower operation of looking over one's shoulder of X-ray video monitor.
3, cooperate shock wave stone crusher to use, accurate positioning also can increase the function of stone crusher, Change present domestic stone crusher and cause the low situation of benefit because the cloth machine is overstocked.
4, because treatment is accurately safe and reliable, the operation indication enlarges, and will have more patient to obtain medical treatment.
