Abstract
The utility model relates to a medical instrument used for orthopedic surgery, particularly to a steel plate used for medical treatment, which comprises a steel plate and a spherical ring, wherein a spherical hole is formed on the steel plate and used for mounting the spherical ring, an internal friction slot is formed on the inner wall of the spherical hole, an external friction slot is formed on the outer wall of the spherical ring and matched with the internal friction slot, and a taper thread is formed on the inner wall of the spherical ring. In the utility model, the inner hole of the spherical ring is the taper thread hole, so that the bolt is not inclined to strip off after connection, and the operation is simpler; the shapes of the spherical ring and the inner hole of the steel plate are both spherical, so that the spherical ring rotates freely inside the spherical hole with less risk of falling off after assembly; the friction slots on the outer wall of the spherical ring and the inner wall of the spherical hole effectively increase the frictional force between the spherical ring and the steel plate, so that the direction of the spherical ring is fixed easily; and the positioning pin effectively prevents the spherical ring from rotating when the screw is screwed in.
Description
Technical field
This utility model relates to a kind of bone surgery medical apparatus, especially a kind of medical steel plate.
Background technology
The present steel plate of using in the medical apparatus and instruments, two kinds of steel plates with the steel plate of adjustable-angle and unadjustable angle.For the adjustable-angle steel plate: screw directly contacts with steel plate hole, deviates from order to prevent screw, also has a part (as locking nail) to screw in the back at screw it is tightened, and operation is complicated; Steel plate screw system for unadjustable angle: screw is connected by taper thread with steel plate, and screw orientation is fixed, and when needing to regulate, just must see that screw screws out, and uses very inconvenient.
The utility model content
The technical problems to be solved in the utility model is: a kind of medical steel plate easy to operate, simple in structure is provided.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of medical steel plate, has steel plate, described steel plate also has ball collar, have the spherical pore that to place ball collar on the steel plate, the inwall of spherical pore is provided with the internal friction groove, the outer wall of ball collar is provided with the external friction groove that matches with the internal friction groove, and the inwall of ball collar is provided with taper thread.
Described on steel plate, also being provided with and the contacted alignment pin of ball collar.
Described alignment pin and steel plate riveted joint.
The beneficial effects of the utility model are that the endoporus of the ball collar in this utility model is provided with taper thread, connects the back screw and is difficult for deviating from, and operates easier; The profile of ball collar and the endoporus of steel plate all are spherical, and assembling back ball collar can freely rotate in spherical pore and be difficult for deviating from; The frictional groove of the outer wall of ball collar and the inwall of spherical pore has effectively increased the frictional force between ball collar and the steel plate, makes ball collar easily directed; Alignment pin can effectively prevent the fashionable ball collar transfer of screw threads.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the sketch map of the internal friction groove on the looping pit inwall.
Fig. 4 is the structural representation of ball collar of the present utility model.
Fig. 5 is the side view of Fig. 3.
Among the figure: 1. steel plate, 1-1. spherical pore, 1-1-1. internal friction groove, 2. ball collar, 2-1. external friction groove, 3. alignment pin.
The specific embodiment
In conjunction with the accompanying drawings this utility model is described in further detail now.These accompanying drawings are the sketch map of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with this utility model.
As Fig. 1, Fig. 2, Fig. 3 and medical steel plate shown in Figure 5, has steel plate 1, steel plate also has ball collar 2, steel plate 1 is provided with and ball collar 2 contacted alignment pins 3, alignment pin 3 and steel plate 1 riveted joint have the spherical pore 1-1 that can place ball collar 2 on the steel plate 1, the inwall of spherical pore 1-1 is provided with internal friction groove 1-1-1, the outer wall of ball collar 2 is provided with the external friction groove 2-1 that matches with internal friction groove 1-1-1, and spherical pore 1-1, alignment pin 3 are four.
Medical steel plate as shown in Figure 4, ball collar 2 inwalls are provided with taper thread.
Intersect in the hole of spherical pore 1-1 and placement positioning pin 3, and after the screw threads that head is had a taper thread was gone into ball collar 2 and screwed, screw just can not deviate from steel plate 1, can be by the direction that relatively rotate adjustment screw of ball collar 2 with steel plate 1.
Claims (3)
1. medical steel plate, has steel plate (1), it is characterized in that: described steel plate also has ball collar (2), have the spherical pore (1-1) that to place ball collar (2) on the steel plate (1), the inwall of spherical pore (1-1) is provided with internal friction groove (1-1-1), the outer wall of ball collar (2) is provided with the external friction groove (2-1) that matches with internal friction groove (1-1-1), and the inwall of ball collar (2) is provided with taper thread.
2. medical steel plate as claimed in claim 1 is characterized in that: described also being provided with on steel plate (1) and the contacted alignment pin of ball collar (2) (3).
