Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, this utility model embodiment is described in further detail.
Embodiment
This utility model embodiment provides a kind of orthopaedics therapy bone splits engaging device, see Fig. 1, described orthopaedics therapy bone splits engaging device comprises support 1, the screw rod 2 be connected with support 1, to match the handle 3 arranged, the occlusal splint 4 being symmetricly set on support 1 both sides with screw rod 2;
See Fig. 2, support 1 comprise rack cross-bar 11, respectively with rack cross-bar 11 the first support brace 12 of being connected of one and the second support brace 13, the first rack vertical rod 14 be integrally connected with the first support brace 12, the second rack vertical rod 15, the first screw 16 be arranged in bottom the first support brace 12, the second screw 17 be arranged in bottom the second support brace 13 that are integrally connected with the second support brace 13; Female thread is provided with in first screw 16 and the second screw 17; First screw 16 hole place, center straight line and the second place, center, screw 17 hole straight line are same straight line; Screw rod 2 is conveniently rotated in screw;
Screw rod 2 comprises and has externally threaded screw body 21, the bolt rotary end 22 be connected with screw body 21, the screw rod draw-in groove (not shown) be arranged in outside bolt rotary end 22; Screw body 21 matches with the first screw 16, second screw 17 respectively and arranges;
The handle round end 32 that handle 3 comprises handle body 31, be connected with handle body 31 by rotating shaft, be arranged on handle projection 33 outside handle body 31; Handle projection 33 and screw rod draw-in groove match and arrange;
Handle projection 33 is blocked and is put in after in screw rod draw-in groove, orthopaedic medical treatment personnel rotate rear drive bolt rotary end 22 to handle round end 32 and rotate, screw rod 2 rotates in screw, and then shorten or expanded stent 1 between distance, drive shortening or the expansion of the spacing of occlusal splint 4 simultaneously, bone splits position is engaged, and constantly adjusts, until make bone splits position be snapped to optimum state;
See Fig. 3, Fig. 4, occlusal splint 4 comprises the first occlusal splint 41 and the second occlusal splint 42 be connected with the first rack vertical rod 14, second rack vertical rod 15 respectively; First occlusal splint 41 is identical with the second occlusal splint 42 structure function, is described in detail in the present embodiment for the first occlusal splint 41;
First occlusal splint 41 comprises the mouth guard 412 be connected with the first rack vertical rod 14 by stage clip 411, the keying aperture 413 be distributed in mouth guard 412, the occlusion projection 415 that is connected with keying aperture 413 outer rim by spring 414; When occlusal splint 4 just clamping bone splits position time, first time can be carried out by spring 414 and clamp buffering; When occlusal splint 4 continues clamping bone splits position, second time can be carried out by stage clip 411 and clamp buffering, secondary buffer, secondary adjustment occlusion clamping, occlusion clamping can be carried out preferably to patient's bone splits position, effectively bone splits place is coupled together, improve bone splits therapeutic effect, reduce patient suffering.
The beneficial effect that the technical scheme that this utility model embodiment provides is brought is:
By arranging the screw rod that can rotate in screw, effectively adjustment bone splits position clamping spacing, until make bone splits position be engaged be clamped to optimum state; Buffer structure is set, when occlusion clamping is carried out to bone splits position, can secondary buffer, secondary adjustment occlusion clamping, can carry out occlusion clamping to patient's bone splits position preferably, effectively bone splits place be coupled together, improve bone splits therapeutic effect, reduce patient suffering.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
