Abstract
The invention relates to a medical appliance for orthopedic surgery, in particular to a steel plate for medical equipment. The steel plate provided by the invention comprises a steel sheet and a spherical ring, wherein the steel sheet is provided with a spherical hole in which the spherical ring can be arranged, the inner wall of the spherical hole is provided with an internal friction groove, the outer wall of the spherical ring is provided with an external friction groove which is anastomotic with the internal friction groove, and a positioning pin is riveted with the steel sheet. The steel plate provided by the invention has the advantages that the inner hole of the spherical hole is a tapered thread hole, therefore, the screw subjected to connection is not easy to drop from the spherical hole, and the operation is simple; the appearance of the spherical ring and the inner hole of the steel sheet are spherical, after the spherical ring and the steel sheet are assembled, the spherical ring can rotate freely in the spherical hole and is not easy to drop from the spherical hole; the outer wall of the spherical ring and the friction groove on the inner wall of the spherical hole effectively increase the frictional force between the spherical ring and the steel sheet, so that the spherical ring is easy to orientate; and the positioning pin can effectively prevent the following rotation of the spherical ring when the screw is screwed into the steel plate.
Description
Technical field
The present invention relates to a kind of bone surgery medical apparatus, especially a kind of steel plate that is used for medical apparatus and instruments.
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.
Summary of the invention
The technical problem to be solved in the present invention is: a kind of steel plate that is used for medical apparatus and instruments easy to operate, simple in structure is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of steel plate that is used for medical apparatus and instruments, 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, also is provided with on steel plate and the contacted alignment pin of ball collar, is provided with taper thread on the inwall of ball collar.
Described alignment pin and steel plate riveted joint.
The invention has the beneficial effects as follows that the endoporus of the ball collar among the present invention is provided with taper thread, connect the back screw and be difficult for deviating from, operate 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
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
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 invention.
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, the present invention is further detailed explanation.These accompanying drawings are the sketch map of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As Fig. 1, Fig. 2, Fig. 3 and the steel plate that is used for medical apparatus and instruments 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.
The steel plate that is used for medical apparatus and instruments 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 (2)
1. steel plate that is used for medical apparatus and instruments, 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), also is provided with on steel plate (1) and the contacted alignment pin of ball collar (2) (3).
2. the steel plate that is used for medical apparatus and instruments as claimed in claim 1 is characterized in that: described alignment pin (3) and steel plate (1) riveted joint.
