Preferably, described expansion marrow bores and keeps highly coaxial with chuck.
Compared with prior art, the invention has the beneficial effects as follows: this equipment is provided with motor, by motor drive expand
Marrow bores and rotates, and improves expansion marrow efficiency, shortens operating time, be provided with one layer of puigging simultaneously on the inwall of shell, can
The sound of isolation motor rotation, is provided with snap ring and screw thread coupling it is only necessary to turn snap ring can bore fixation, behaviour by expanding marrow
Facilitate, be also convenient for doctor simultaneously and change expanding broken brill, be internally provided with accumulator it is not necessary to external cable in handle, it is to avoid
Cable disturbs surgical, is provided with graduation mark with expanding the brill that marrow bores, and is easy to doctor and de-spreads the working depth that marrow bores, no
Need by extra instrument, reduce the fussy degree of operation.
