Description
Technical field
ThisInventionBelong to Medical orthopedic electric drill, especiallyA kind of improved orthopaedic drill of structure.
Background technology
At present, in the fixing operation of orthopaedics, need to hole on bone, and present rig is hand held electric drill.When using, entirely lean on doctor with sensation operation, the depth for boring can not accurately be held, lead to the precision holed low, and waste of manpower, drilling time is long, thus extending whole operating time.In boring procedure, osseous tissue chip can splash, or even is splashed to operation doctor, also makes troubles to debridement.
Content of the invention
ThisInventionThere is providedA kind of improved orthopaedic drill of structure, its objective is to carry out structure improvement to existing electric drill, thus solution must not accurately hold drilling depth and the problem that can not prevent from splashing.
In order to solve above-mentioned technical problem, thisInventionTechnical scheme be：A kind of improved orthopaedic drill of structure, including the electric drill of hand-held, the outfan of electric drill be provided with drill bit it is characterised in that：Drill bit is provided with limiting plate, limiting plate can be slid axially along drill bit by drill guide bore thereon, linking arm has been extended downwardly at the side of limiting plate, it is provided with screw rod pilot hole in linking arm, screw rod guiding in the hole is provided with screw rod, and screw rod is be arranged in parallel with drill bit, and limiting plate can slide axially along a screw, linking arm is fixed on screw rod one end by the back tightening nut of its both sides, and the other end of screw rod is fixedly connected with the shell of electric drill；The end face of the corresponding human body of limiting plate is provided with splash guard.
The further restriction to technique scheme, the end face of described limiting plate is provided with the open slot communicating with drill guide bore.Open slot is easy to limiting plate Fast Installation on drill bit.
The further improvement to technique scheme, described splash guard includes the taper cover body being made up of transparent soft plastic thin film, and the osculum end of taper cover body is provided with the iron plate of ring-type, and the big opening end of taper cover body is provided with the silica gel cushion of ring-type；The other end of limiting plate is provided with Magnet, and the iron plate end of splash guard is fixedly connected with limiting plate by Magnet.This splash guard has the advantages that structure is simple, Fast Installation, the suitability are high.
Beneficial effect：1. the limiting plate on drill bit carries out position adjustments by screw rod and back tightening nut, thus controlling drill bit to go deep into the depth in bone, solves the problems, such as can not accurately hold drilling depth；2. screw rod and back tightening nut have the advantages that structure is simple, the spacing Board position of quick regulation and high precision；3. limiting plate is provided with splash guard, and solution must not prevent the problem that osseous tissue splashes；4. one end of screw rod need to being fixed on existing electric drill, just completing the structure of modification to existing electric drill, thus avoiding the problem of the wasting of resources；5.InventionThere is structure simple, easy to use, the advantage of high working efficiency.
Brief description
Figure 1It is thisInventionStructural representationFigure.
Figure 2It isFigure 1In limiting plate overlookFigure.
Specific embodiment
As figure 1WithFigure 2It is shown,A kind of improved orthopaedic drill of structure, electric drill 1 including hand-held, the outfan of electric drill 1 is provided with drill bit 2, drill bit 2 is provided with limiting plate 3, the center of limiting plate 3 is provided with drill guide bore, limiting plate 3 is provided with the open slot 4 communicating with drill guide bore, drill bit 2 is arranged in the drill guide bore on limiting plate 3, limiting plate 3 can slide axially along drill bit 2, linking arm 5 has been extended downwardly at the side of limiting plate 3, it is provided with screw rod pilot hole in linking arm 5, screw rod guiding in the hole is provided with screw rod 6, screw rod 6 is be arranged in parallel with drill bit 2, limiting plate 3 can slide axially along screw rod 6, linking arm 5 is fixed on screw rod 6 one end by the back tightening nut 7 of its both sides, the other end of screw rod 6 is fixedly connected with electric drill 1；The end face of the corresponding human body of limiting plate 3 is provided with splash guard, and splash guard includes the taper cover body 8 being made up of transparent soft plastic thin film, and the osculum end of taper cover body 8 is provided with the iron plate 9 of ring-type, and the big opening end of taper cover body 8 is provided with the silica gel cushion 10 of ring-type；The other end of limiting plate 3 is provided with Magnet 11, and the iron plate end of splash guard is fixedly connected with limiting plate 3 by Magnet 11.
Operation principle：First limiting plate is installed on drill bit, the linking arm on limiting plate is connected with screw rod by back tightening nut, does not temporarily tighten nut, after limiting plate after the position on drill bit determines, tighten back tightening nut；Again the iron plate end of splash guard is fixed on the end face of the corresponding human body of limiting plate by Magnet；Finally the silica gel cushion on splash guard is fitted on human body, and start electric drill and holed.
Claims (3)
1. the improved orthopaedic drill of a kind of structure, including the electric drill of hand-held, the outfan of electric drill be provided with drill bit it is characterised in that：Drill bit is provided with limiting plate, limiting plate can be slid axially along drill bit by drill guide bore thereon, linking arm has been extended downwardly at the side of limiting plate, it is provided with screw rod pilot hole in linking arm, screw rod guiding in the hole is provided with screw rod, and screw rod is be arranged in parallel with drill bit, and limiting plate can slide axially along a screw, linking arm is fixed on screw rod one end by the back tightening nut of its both sides, the other end of screw rod and the cage connection of electric drill；The end face of the corresponding human body of limiting plate is provided with splash guard.
