Further, before and after described power shaft, side is provided with the bearing for supporting motive force rotating shaft.
Further, described power passes shaft rear end and stretches out in order to operation from hollow bar section rear port, and described power passes axle front end penetrates warping part, hollow bar section front side inner chamber burr cutter head driving member through the first Hooks coupling universal coupling and the second Hooks coupling universal coupling and rear end and is in transmission connection.
Further, described burr cutter head driving member front end is provided with to clamp the rotary chuck of burr cutter head.
Further, top cover and bottom end cover snapping that described hollow bar section is connected on connecting rod by rear sidewall form, and warping part, described top cover front side has hollow sleeve, and described end cap rear side is provided with lower flange.
Further, described connecting rod is provided with longitudinal hole and matches to block above-mentioned bottom end cover lower flange with screw rod.
Compared with prior art, the utlity model has following advantage: this utility model is not only conducive to doctor's operation task, and can effectively reduce the wound size of operating theater instruments introducing port, the about 5-6cm of operative incision, do not need to peel off too much soft tissue in visual area, can retain the important structure such as joint capsule, be conducive to postoperative joint stable, reduce patient's wound; This device is handled shaft and is adopted the radian that meets acetabular bone expanded angle simultaneously, and ligament soft tissue is impaired little, is conducive to postoperation recovery, and recovery effects is good.

The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but this utility model is not limited to this.
With reference to figure 1, Fig. 2, a kind of acetabular bone burr adapter, comprise hollow bar section 1 and handle portion 2, described handle portion centrage extended line 21 intersects acute angle 3 with hollow bar section centrage 11, handle upper end is connected through connecting rod 4 with hollow bar section rear sidewall, described hollow bar section main body inner chamber is equipped with power shaft 5, described power shaft front end is in transmission connection through Hooks coupling universal coupling 6 and the burr cutter head driving member 8 of warping part, hollow bar section front side 7 inner chambers, and described warping part centrage and hollow bar section centrage angle are that perk angle 71 is 30 ° ~ 60 °.
In order to reduce the frictional force of power shaft and hollow bar section, before and after described power shaft, side is provided with the bearing 9 for supporting motive force rotating shaft.
In the present embodiment, described power passes shaft rear end and stretches out to be connected with the driving device such as electric drill and order about power and pass axle and rotate from hollow bar section rear port 12.In order to facilitate power to pass axle in the be upturned power transmission of portion of hollow bar section, described power passes axle front end and is in transmission connection with the burr cutter head driving member that rear end penetrates warping part, hollow bar section front side inner chamber through the first Hooks coupling universal coupling 61 and the second Hooks coupling universal coupling 62.
In the present embodiment, described burr cutter head driving member front end is provided with to clamp the rotary chuck 81 of burr cutter head.
In the present embodiment, for the ease of power, passing axle is arranged in hollow bar section, the top cover 13 that described hollow bar section is connected on connecting rod by rear sidewall forms with bottom end cover 14 snappings, warping part, described top cover front side 7 is hollow sleeve, the rear end of burr cutter head driving member is in the inner chamber of threading, to after top cover and bottom end cover snapping, form hollow bar section, described end cap rear side is provided with lower flange 141.
In the present embodiment, described connecting rod is provided with longitudinal hole 41 and matches to block above-mentioned bottom end cover lower flange with screw rod 10, prevents that end cap and top cover from departing from, simultaneously also for convenience detach.The corresponding end-faces at longitudinal hole place is provided with cross clamping groove, to block the T connector of screw end head.Handle portion adopts and is threaded with connector lower end, can post plastic anti-skid cover in handle portion outside, so that surgical operation simultaneously.
In hip joint Reconstruction, burr cutter head is stuck on rotary chuck, the union joint of electric drill is connected with the termination that power passes shaft rear end simultaneously.Acetabular bone burr adapter penetrates from operative incision, because using the arcuate structure that meets acetabular bone expanded angle, surgical wound is less, now aim at the acetabular bone position that needs burr, the motion of driving electric drill, power is sent to burr cutter head through power shaft, and burr cutter head starts burr acetabular bone, after burr is good, burr adapter is taken out from wound again.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to this utility model claim change and modify, and all should belong to covering scope of the present utility model.
