When assembling, central shaft 2 is inserted medium pore 11 by the one end from the rearward end of shell 1 with striking head 13, until end difference 23 contacts with block platform 111, now, the extension 22 of central shaft 2 is before window 12; Knob 3 is positioned in window 12, the centrage of the polygon endoporus of knob 3 is overlapped with the centrage of medium pore 11; Promote rearwards again central shaft 2, the polygon auxiliary section 24 of central shaft 2 rearward end and the polygon endoporus of knob 3 are coordinated; The last extension 22 that by threaded engagement, anti-falling piece 4 is connected to central shaft 2 by observation window 15.
Embodiment 2
As shown in Figure 7 to 10, this utility model is held and is got driver the second embodiment, comprises tube-like envelope 1, central shaft 2, knob 3 and anti-falling piece 4.
Tube-like envelope 1 front end has longitudinal medium pore 11, and is provided with window 12, dish type striking head 13, grip part 14, observation window 15, knob 3 as described in example 1 above.
Central shaft 2 matched in clearance are in medium pore 11, and the leading section of central shaft 2 stretches out shell 1 leading section, and rearward end stretches into window 12.The leading section of central shaft 2 has external screw thread 21, this external screw thread 21 can with type femoral bone end prosthesis on screw-internal thread fit.
The auxiliary section 24 of central shaft 2 rearward end coordinates with knob 3 as described in example 1 above.
Central shaft 2 is provided with the end difference 23 that a diameter is greater than auxiliary section 24 diameters, is positioned at before knob 3, before end difference extends to, is connected with external thread part 21.
Equally; the anti-falling piece 4 being connected with central shaft 2 in the interior setting of observation window 15; anti-falling piece 4 structure as described in example 1 above; prevent that central shaft 2 from excessively being deviate from forward by medium pore 11; the auxiliary section 24 of maintenance central shaft 2 and knob 3 are always in mated condition; and it is long that the front end of central shaft 2 can not stretch out shell 1, and the front end of central shaft 2 is played a protective role.
The diameter of the end difference 23 on central shaft 2 is greater than the diameter of auxiliary section 24, and is greater than the interior diameter of knob 3, for preventing that central shaft 2 from deviating from from shell 1 rear end.
Equally, in other embodiments, shell 1 leading section is provided with boss 16, and the concave shape on the type femoral bone end prosthesis in the shape of this boss 16 and part model matches.
When assembling, first knob 3 is positioned in window 12, the centrage of the polygon endoporus of knob 3 is overlapped with the centrage of medium pore 11, then from the front end of shell 1, central shaft 2 is inserted to medium pore 11, the polygon auxiliary section 24 of central shaft 2 rearward end and the polygon endoporus of knob 3 are coordinated; The last extension 22 that by threaded engagement, anti-falling piece 4 is connected to central shaft 2 by observation window 15.
When use, hand-held grip part 14, screws knob 3, and rotary middle spindle 2 makes the screw-internal thread fit on external screw thread and the type femoral bone end prosthesis of central shaft 2 leading sections; Continue to screw knob 3, until the front end face of type femoral bone end prosthesis butt shell 1 stops screwing, complete holding of type femoral bone end prosthesis got to action.Then, knock the striking head 13 of shell 1 rearward end, percussion power is passed to its leading section by striking head 13 along shell 1, and is further passed to type femoral bone end prosthesis, thereby type femoral bone end prosthesis is inserted to pulp cavity, completes and impacts insert action.In the time that type femoral bone end prosthesis is provided with depression, can coordinate shell 1 leading section to get driver with holding of boss 16.
In this utility model, held and got type femoral bone end prosthesis by central shaft 2, transmit percussion power by shell 1, central shaft 2 can move forward and backward with respect to shell 1.That is to say, of the present utility model hold get driver to holding of type femoral bone end prosthesis get action and stroke be separate, the two is non-interference.Therefore, hold not get when type femoral bone end prosthesis and put in place, be type femoral bone end prosthesis not with shell 1 leading section butt situation under, while knocking the striking head 13 of shell 1, shell 1 can be with respect to central shaft 2 (to type femoral bone end prosthesis direction) movement forward, until with type femoral bone end prosthesis butt, make percussion power still be directly delivered to type femoral bone end prosthesis by shell 1, central shaft 2 is drawn back under retroaction, the threaded portion 21 of guaranteeing central shaft 2 front ends does not stress, thereby can not damage the external screw thread of central shaft 2 leading sections and the female thread of type femoral bone end prosthesis, therefore use this utility model to hold and get driver, can prevent from holding and getting the screw thread of damaging not in place because of bone thigh handle, hold the spoilage of getting driver and type femoral bone end prosthesis thereby reduced, save cost.
This utility model not only can be used for holding getting squeezes into hip joint stalk prosthese, can also be used for holding and get reamer for hip arthroplasty.Further, can also use this apparatus to complete holding to get and squeezing into of hip cotyle cup and the die trial of mortar cup, hold the mode of getting driver knob 3 and be connected with the threaded portion of mortar cup die trial (or prosthese) holding the central shaft 2 front end threaded portions 21 of getting driver by screwing, put into the urgent compacting of mortar nest, can play equally the effect that can not damage central shaft 2 in strike process.
Although described this utility model with reference to several exemplary embodiment, should be appreciated that term used is explanation and exemplary and nonrestrictive term.Because this utility model can specifically be implemented in a variety of forms and not depart from spirit or the essence of utility model, so be to be understood that, above-mentioned embodiment is not limited to any aforesaid details, and explain widely in the spirit and scope that should limit in the claim of enclosing, therefore fall into whole variations in claim or its equivalent scope and remodeling and all should be the claim of enclosing and contain.
