The utility model discloses a backbone screw series connection subassembly for orthopedics is in the same place the backbone screw series connection, and this series connection group price can play and pull, twist reverse, reset etc. and effect, the backbone and the joint that will shift are corrected to resume normal backbone relation, reach and correct or fixed purpose.
Description
Technical Field
The utility model relates to the field of medical equipment, specifically speaking, the utility model relates to an orthopedics is with backbone screw series connection subassembly.
Background
The spine screw is a medical device widely applied to spine correction operations of the spine, cervical vertebra, lumbar vertebra and the like, the spine screw is put into the spine of a patient, then fixing plates or fixing rods are used for connecting the spine screws, a vertebral body combined fixing system formed by connecting the fixing plates is called a nail-plate fixing system, a vertebral body combined fixing system formed by connecting the fixing rods is called a nail-rod fixing system, and the fixing rods in the nail-rod fixing system can be one or more. The vertebral body combined fixing system can correct the displaced spine and joints by applying a lever principle and using a three-dimensional space method of traction, torsion and reduction so as to restore the normal relationship of the spine and achieve the aim of correction or fixation.
Disclosure of Invention
The utility model aims to solve the technical problem that a backbone screw series connection subassembly is provided, this subassembly can be in the same place the backbone screw series connection.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: the utility model provides a backbone screw series connection subassembly for orthopedics, includes the series connection subassembly, the afterbody cover of series connection subassembly is on backbone screw, and two adjacent backbone screws go up the articulated together of fixed series connection subassembly, the series connection subassembly includes fastening arm and digging arm, and the whole "Y" shape that is of series connection subassembly, and the digging arm is equipped with two, and two digging arms are connected on fastening arm, and fastening arm overlaps on backbone screw through the retainer plate that sets up at the afterbody, and two adjacent digging arms pass through the pin and articulate together.
Preferably, a spring is arranged between the two movable arms on the tandem assembly.
Preferably, the spring is a strip spring, and the strip spring is bent between the two movable arms in a U shape.
Adopt the technical scheme of the utility model, can obtain following beneficial effect:
the utility model discloses a backbone screw series connection subassembly for orthopedics is in the same place the backbone screw series connection, and this series connection subassembly can play and pull, twist reverse, effect such as reset, corrects the backbone and the joint that shift to resume normal backbone relation, reachs and corrects or fixed purpose.
Drawings
The contents of the description and the references in the drawings are briefly described as follows:
FIG. 1 is a first schematic structural view of the present spinal screw tandem assembly;
FIG. 2 is a second schematic structural view of the spinal screw tandem assembly;
the labels in the above figures are: 1. a series assembly; 2. a spinal screw; 3. a fastening arm; 4. a stationary ring; 5. a movable arm; 6. a spring; 7. a pin.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings, in which the shapes, structures, mutual positions and connection relationships of the respective members, the functions of the respective portions, the operation principles, and the like of the respective members are described.
As shown in figure 1, this backbone screw series connection subassembly for orthopedics includes series connection subassembly 1, the afterbody cover of series connection subassembly 1 is on backbone screw 2, the series connection subassembly 1 of fixing is articulated together on two adjacent backbone screws 2, series connection subassembly 1 includes fastening arm 3 and digging arm 5, series connection subassembly 1 is whole to be "Y" shape, digging arm 5 is equipped with two, two digging arms 5 are connected on fastening arm 3, fastening arm 3 overlaps on backbone screw 2 through the retainer plate 4 that sets up at the afterbody, two adjacent digging arms 5 are articulated together through pin 7. Set up spring 6 between two digging arms 5 on the series connection subassembly 1, spring 6 is bar spring, and bar spring is "U" shape crooked between two digging arms 5, and spring 6's setting has increased the elasticity between two digging arms 5, is favorable to the torsion and the reseing of backbone.
As shown in figure 1, when in use, the spinal screw 2 is screwed into the spinal column, then the serial connection component 1 is sleeved on the spinal screw 2 and fixed, and two adjacent movable arms 5 on the serial connection component are hinged together through the pin 7, so that a plurality of spinal screws 2 can be combined and connected in series.
As shown in fig. 2, the series connection component 1 can be in a multiple combination mode, and two groups of series connection components 1 can be arranged on the same spinal screw 2 according to requirements, so that the tension between the two spinal screws 2 is stronger, and the spinal column is restored. The spine screw 2 inserted between the spines pulls, twists and resets the spines under the action of the serial components 1, and the serial components 1 reset the spines through the tension between every two serial components 1.
The spinal screw serial component 1 connects the spinal screws 2 together in series, and the serial component 1 can play roles of traction, torsion, reduction and the like, correct the displaced spinal column and joints so as to restore the normal spinal relation and achieve the purpose of correction or fixation.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
