Abstract
The present invention relates to a kind of bone surgery medical apparatus, especially a kind of steel plate for medical instrument, with steel plate, steel plate also has ball collar, the spherical pore that can place ball collar is provided on steel plate, the inner wall of spherical pore is equipped with interior frictional groove, and the outer wall of ball collar is equipped with the external friction slot to match with interior frictional groove, and positioning pin and steel plate rivet.The inner hole of ball collar in the present invention is taper thread hole, and screw is not easy after connection, is operated easier；The shape of ball collar and the inner hole of steel plate are all spherical shape, and ball collar can be freely rotated in spherical pore and be not easy after assembly；The outer wall of ball collar and the frictional groove of spherical pore inner wall effectively increase the frictional force between ball collar and steel plate, orient ball collar easily；Ball collar transfer when screw screws in can be effectively prevented in positioning pin.
Description
Technical field
The present invention relates to a kind of bone surgery medical apparatus, especially a kind of steel plate for medical instrument.
Background technique
Steel plate in medical instrument at present, two kinds of steel plate of steel plate and unadjustable angle with adjustable-angle.
For adjustable-angle steel plate: screw is directly contacted with steel plate hole, and screw is deviate from order to prevent, and there are also a part (such as locking nails)
It is tightened after screw screw-in, is operated more complex；For the steel plate screw system of unadjustable angle: screw and steel plate
It is connected by taper thread, screw orientation is fixed, and when needing to adjust, must just see that screw screws out, use is very inconvenient.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of steel easy to operate, structure is simply to medical instrument
Plate.
The technical solution adopted by the present invention to solve the technical problems is: a kind of steel plate for medical instrument, has steel
Plate, the steel plate also have ball collar, and the spherical pore that can place ball collar is provided on steel plate, and the inner wall of spherical pore is equipped with interior
Frictional groove, the outer wall of ball collar are equipped with the external friction slot to match with interior frictional groove, are additionally provided on the steel plate and ball collar
The positioning pin being in contact is equipped with taper thread on the inner wall of ball collar.
The positioning pin and steel plate rivets.
The invention has the advantages that the inner hole of the ball collar in the present invention is equipped with taper thread, screw is not easy to take off after connection
Out, it operates easier；The shape of ball collar and the inner hole of steel plate are all spherical shape, and ball collar can freely turn in spherical pore after assembly
It moves and is not easy；The frictional groove of the inner wall of the outer wall and spherical pore of ball collar effectively increases rubbing between ball collar and steel plate
Power is wiped, orients ball collar easily；Ball collar transfer when screw screws in can be effectively prevented in positioning pin.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Fig. 3 is the schematic diagram of the interior frictional groove on looping pit inner wall.
Fig. 4 is the structural schematic diagram of ball collar of the invention.
Fig. 5 is the side view of Fig. 3.
In figure: 1. steel plates, 1-1. spherical pore, frictional groove in 1-1-1., 2. ball collars, 2-1. external friction slot, 3. positioning pins.
Specific embodiment
In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, Figure 2, Fig. 3 and the steel plate shown in fig. 5 for medical instrument have steel plate 1, and steel plate also has ball collar
2, the positioning pin 3 being in contact with ball collar 2 is provided on steel plate 1, positioning pin 3 and steel plate 1 rivet, be provided with and can put on steel plate 1
Set the spherical pore 1-1 of ball collar 2, the inner wall of spherical pore 1-1 is equipped with interior frictional groove 1-1-1, the outer wall of ball collar 2 be equipped with
External friction slot 2-1, spherical pore 1-1 that interior frictional groove 1-1-1 matches, positioning pin 3 are four.
Steel plate for medical instrument as shown in Figure 4,2 inner wall of ball collar are equipped with taper thread.
Spherical pore 1-1 intersects with the hole of placement positioning pin 3, and the screw by head with taper thread screws in ball collar 2 and revolves
Next, screw would not deviate from steel plate 1, and the direction of screw can be adjusted by the relative rotation of ball collar 2 and steel plate 1.
