Abstract
The utility model relates to a drill bush clamping device for the osteology department. The device comprises a fixing head which is arranged at the front end of a fixing rod and is used for clamping a drill bush. The device is structurally characterized in that the fixing head consists of an upper clamping block and a lower clamping block with symmetrical shapes, the lower clamping block is integrally connected with the fixing rod, and the upper clamping block is hinged with the front end of the fixing rod. The inner side of the upper clamping block and the inner side of the lower clamping block are correspondingly provided with two sets of arc-shaped grooves to form two drill bush holes, and a clamping bolt is arranged between the two drill bush holes. The upper clamping block is designed to be a movable 'press cover', and the pressure to the two holes is even, so that the drill bush clamping device is firm in clamping, convenient in operation, and exact and reliable in positioning, so that the drilling position is guaranteed to be accurate, and the operation quality is improved.
Description
Technical field
This utility model relates to the orthopaedics medical apparatus and instruments, relates to the localized drill bushing clamping device of boring in the bone surgery specifically.
Background technology
Traditional orthopaedics drilling guide device, be that fixing head at fixed bar partly is processed with the circular hole that is used for the plug-in mounting drill bushing, fix by the machining accuracy realization drill bushing in hole fully, not only difficulty of processing is big, and after using a period of time, because the wearing and tearing in hole can make drill bushing accurate positioning reduction, cause the bore position skew, influence operation quality.For addressing the above problem, the design people provides a kind of orthopaedics drill bushing fixture, and it is to be processed with opening longitudinally on the fixing head of fixed bar, and each drill bushing hole has been divided into two parts up and down, and the reuse fishbolt clamps drill bushing.Though this device has improved the clamping effect, because fixing head remains one, need bigger pressure if will clamp the drill bushing in two holes simultaneously, operation easier is big, can not clamp simultaneously sometimes.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of easy to use, effective, the safe and reliable orthopaedics of clamping drill bushing clamping device is provided.
This utility model orthopaedics drill bushing clamping device, has the fixing head that is used to clamp drill bushing that is arranged on the fixed bar front end equally, its construction features fixing head is made up of the symmetric clamp down of shape and upper clamping block two parts, following clamp and fixed bar are connected to one, the fixed bar end has the cambered surface groove, the upper clamping block rear end has and the corresponding union joint of this groove shapes, and union joint is installed in the groove, makes upper clamping block and fixed bar front end form hinged.The inboard of infra clamp and upper clamping block is provided with two groups of arcuate grooves accordingly, and every group two arcuate groove constitutes a drill bushing hole, and one and the axial vertical fishbolt in drill bushing hole are housed between two drill bushing holes.
Above-mentioned orthopaedics drill bushing clamping device, the inboard of infra clamp and upper clamping block is processed with spring groove respectively, and the spring that is sleeved on the fishbolt is arranged in the spring groove, so that drill bushing clamps and installs.
Owing to fixing head of the present utility model is made up of the symmetric clamp down of shape and upper clamping block two parts, be about to upper clamping block and be designed to an activity " gland ", no longer there is pressure inequality to two holes, thereby clamp firmly, easy to operate, accurate positioning is reliable, has guaranteed that bore position deviation can not occur, has improved the operation quality.
Description of drawings
Fig. 1 is a main cutaway view of the present utility model, shows its overall structure.
The specific embodiment
In the embodiment that accompanying drawing provides, the utlity model has the fixing head that is arranged on fixed bar 1 front end, this fixing head is by clamp 2 and upper clamping block 3 two parts are formed down, following clamp 2 is connected to one with fixed bar 1, fixed bar 1 end has cambered surface groove 5, upper clamping block 3 rear ends have the union joint 4 that is installed in this groove 5, and promptly upper clamping block and fixed bar front end form hinged.The inboard of infra clamp 2 and upper clamping block 3 is provided with two groups of arcuate grooves 21,31,22,32 accordingly, every group two arcuate groove constitutes a drill bushing hole that is used to clamp drill bushing, at the bolt hole that has processing between two drill bushing holes on clamp up and down, the bolt hole of following clamp 2 is threaded, and one and the axial vertical fishbolt 6 in drill bushing hole are housed on the clamp up and down.The inboard of infra clamp 2 and upper clamping block 3 also is processed with spring groove respectively, and the spring 7 that is sleeved on the fishbolt 6 is arranged in the spring groove, so that drill bushing clamps and installs.
