Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-4, a universal auto-lock coaptation board, includes coaptation board main part 1, coaptation board main part 1 in be equipped with a plurality of card hole 2, inside sunken circular arc draw-in groove 3 that forms all around of card hole 2 still includes the latch segment 4 that is located card hole 2, the outer lane of latch segment 4 outwards extends the circular arc arch 5 that forms with circular arc draw-in groove 3 looks adaptation, latch segment 4 on offer the fracture 6 that is used for elastic deformation, latch segment 4 in be equipped with and be used for fixed locking screw 7.
When the locking device is used, the locking screw 7 is continuously screwed into the locking block 4, the locking block 4 can expand and contract within the elastic deformation range due to the fracture 6, and the locking block 4 is continuously expanded along with the continuous screwing of the locking screw 7, so that the locking block is clamped on the clamping hole 2. And because the design of circular arc draw-in groove 3 and circular arc arch 5 for when fixed, thereby the regulation of realization angle of latch segment 4 can be at the rotation of card hole 2, after adjusting the angle, the chucking function of expanding of latch segment 4 is realized to rethread foretell structure.
In this embodiment, the locking block 4 in be equipped with first awl screw thread 8, the upper end of locking screw 7 is equipped with second cone screw thread 9, the lower extreme of locking screw 7 is equipped with external screw thread 10, first awl screw thread 8 and second cone screw thread 9 cooperate, external screw thread 10 screw in fracture line in. In order to guarantee that latch segment 4 can expand to design into awl thread fit's formation, when locking screw 7 selected inwards, the screw thread can be big more, thereby expand latch segment 4, until latch segment 4 and card hole chucking, external screw thread 10 of locking screw 7 lower extreme is mainly fixed bone plate main part 1 in adjusting the screw in to the broken bone line.
In this embodiment, the locking screw 7 may be in any direction within 30 ° from the center line of the locking block 4. Through the circular arc draw-in groove 3 and the circular arc arch 5 of looks adaptation, can realize the universal regulation of latch segment 4 and locking screw 7 in calorie hole 2, and because the restriction in the aspect of size such as the thick and 4 thicknesses of latch segment, it can be adjusted wantonly at 30 within ranges to realize locking screw 7 screw in to the broken bone line through adjusting.
In this embodiment, the upper end of the locking block 4 is symmetrically provided with openings 11 for facilitating screwing. Thereby make things convenient for medical personnel to use common word screwdriver or cross screwdriver to place and carry out the screw in opening 11, improved screw in efficiency to can guarantee the screw in dynamics, make latch segment 4 and card hole 2 fully cooperate the chucking.
In the embodiment, the bone plate body 1 is provided with a plurality of fixing screw holes 12. When fixing butt joint bone plate main part 1, through locking screw 7 fixed back, installation screw carries out dual fixed in the fixed screw 12 of rethread, guarantees the fixed stability and the fastness of coaptation board main part 1, prevents that coaptation board main part 1 is fixed insecure and leads to the recovered effect of patient's fracture not good.
In the embodiment, the bone plate body 1 is provided with an adjusting groove 13. The position of the screw fixation and the bone fracture plate can be adjusted through the adjusting groove 11, so that some interference points or fixing points which cannot be fixed are avoided, and the operation of medical staff is facilitated.
