Description
Technical field
The utility model discloses a kind of cover-lifting type spinal column and follow closely excellent staple, belong to spinal column and repair the inside-fixture technical field.
Background technology
In daily life,, groups of people's spinal column is sustained damage, the spinal disease that the unstable spine that causes as wound is fixed, rheumatism and tumor cause, congenital and iatrogenic, heritability spinal disease, and degeneration spinal disease owing to multiple reason.These reasons can cause that all spinal column can not keep normal physiological status, cause symptoms such as patient's hunchback, lateral bending, can't orthobiosis.In order to treat these diseases, often adopt the mode of staple rod fixed system on patient's spinal column, help the patient to recover the normal morphology of spinal column.The excellent fixed system of this nail mainly is made up of staple and support stick.The structure of the staple of the nail rod fixed system that adopts at present, it is thicker to make the nail rod expose outside the part of bone surface, and the operation incisura is higher, causes bigger misery and inconvenience to the patient.In addition, when patient's osteoporosis, staple combines insecure with osseous tissue, makes staple loosening easily, causes fixing unstable.
The utility model content
The purpose of this utility model is that a kind of cover-lifting type spinal column of design is followed closely excellent staple, can reduce the operation incisura, the part that makes the nail rod expose outside bone surface reduces, staple can be combined with osseous tissue firmly, it is fixing unstable to prevent that osteoporosis from causing, reduce operating time, alleviate patient suffering and inconvenience.
The technical solution adopted in the utility model is made up of cover-lifting type ailhead, bulb nail, attaching nut, lock-screw, the cover-lifting type ailhead is made up of ailhead seat, upper cover plate and pin, have a circular groove in the middle of the ailhead seat, have a bulb screw below the ailhead seat, the ailhead seat has pin-and-hole on one side, and another side has the locking screw; Upper cover plate is connected with the ailhead seat by pin, and upper cover plate is fixed by lock-screw and ailhead seat; The bulb nail is connected in the bulb screw below the ailhead seat by the attaching nut.
Have vertical hole in the nail body of described bulb nail.
Have side opening in the nail body of described bulb nail, side opening is communicated with vertical hole.
The upper end in the vertical hole in the described bulb nail is threaded.
The designed cover-lifting type spinal column of this utility model is followed closely excellent staple and is had following advantage:
1, it is small and exquisite that the cover-lifting type spinal column is followed closely excellent staple structure, can form small and exquisite, short nail rod fixed system with support stick, reduces the operation incisura, and the part that makes the nail rod expose outside bone surface reduces, and alleviates patient suffering and inconvenience.
2, it is safe and reliable that the cover-lifting type spinal column is followed closely excellent staple.The bulb nail combines with osseous tissue firmly, when patient's osteoporosis, can in loose osseous tissue, fill bone cement by vertical hole and the side opening that is communicated with it, strengthen the adhesion of bulb nail and osseous tissue, thereby spinal column is followed closely excellent staple and can be formed reliably and connect, in use not fragile, safe.
3, to follow closely excellent staple easy to use flexibly for the cover-lifting type spinal column.Can utilize guide pin accurately to locate in pedicle locations, it be fixing with its implantation more then the bulb nail to be penetrated guide pin through vertical hole in advance, can prevent effectively that like this bulb nail is because of locating the inaccurate spinal cord injury that causes.The cover-lifting type ailhead can make support stick lay easily, is convenient to operation, and cover-lifting type ailhead and bulb nail are ball-joint, and connection angle can be adjusted, and makes the cover-lifting type spinal column follow closely excellent staple and support stick is easy to connect, save time, and the minimizing operating time alleviates the patient suffering.

The specific embodiment
The structural representation that the described cover-lifting type spinal column of present embodiment is followed closely excellent staple is seen Fig. 1, Fig. 2 and shown in Figure 3.
The cover-lifting type spinal column is followed closely excellent staple and is made up of cover-lifting type ailhead, bulb nail 1, attaching nut 2, lock-screw 3, the cover-lifting type ailhead is made up of ailhead seat 4, upper cover plate 5 and pin 6, have a circular groove 7 in the middle of the ailhead seat 4, have a bulb screw 8 below the ailhead seat, one side of ailhead seat has pin-and-hole 9, and another side has locking screw 10; Upper cover plate 5 is connected with ailhead seat 4 by pin 6, and upper cover plate 5 is fixing with ailhead seat 4 by lock-screw 3; Bulb nail 1 is connected in the bulb screw 8 below the ailhead seat 4 by attaching nut 2.
In the operation, needs according to patient treatment, several cover-lifting type spinal columns are followed closely excellent staple to be fixed on patient's the spinal column with bulb nail 1, open the upper cover plate 5 on the cover-lifting type ailhead, support stick 11 is put into ailhead seat 4 intermediary circular grooves 7, close upper cover plate 5 then, with lock-screw 3 upper cover plate 5 is fixed on the ailhead seat 4, upper cover plate 5 is connected to support stick 11 in the ailhead seat 4 intermediary circular grooves 7.Several cover-lifting type spinal columns follow closely excellent staple and the excellent fixed system of nail is formed in support stick 11 fastening backs, are fixed on patient's spinal column, help to correct, support patient's spinal column, reach therapeutic purposes.
The designed cover-lifting type spinal column of this utility model is followed closely excellent staple, and to have structure small and exquisite, can form small and exquisite, short nail rod fixed system with support stick, and the operation incisura is low, and the part that makes the nail rod expose outside bone surface reduces.The cover-lifting type spinal column is followed closely excellent staple can form connection reliably, in use not fragile, safe.It is easy to use flexibly that the cover-lifting type spinal column is followed closely excellent staple, easy to connect with support stick, save time, and can reduce operating time, alleviates the patient suffering.
The structural representation that the described cover-lifting type spinal column of present embodiment is followed closely excellent staple is seen shown in Figure 4.
It is basic identical that the described cover-lifting type spinal column of present embodiment is followed closely the structure that excellent staple and embodiment 1 described cover-lifting type spinal column follow closely excellent staple, and difference is to have vertical hole 12, side opening 13 and screw thread 14 in the middle of the bulb nail 1.
In operation, bulb nail 1 directly can be screwed on the required skeleton position of patient treatment, if patient's osteoporosis, can in loose osseous tissue, fill bone cement by vertical hole 12 and the side opening 13 that is communicated with it, strengthen the adhesion of bulb nail 1 and osseous tissue, bulb nail 1 is formed reliably connect, it is fixing unstable to prevent that osteoporosis from causing.Screw thread 14 is used for connecting the bone cement syringe, and syringe is fixed when making the injection bone cement, and bone cement does not leak.
In operation, can also utilize guide pin accurately to locate in pedicle locations in advance, it is fixing with its implantation more then bulb nail 1 to be penetrated guide pin through vertical hole 12, can prevent effectively that like this bulb nail 1 is because of locating the inaccurate spinal cord injury that causes.
Other advantages that the described cover-lifting type spinal column of present embodiment is followed closely excellent staple are described identical with embodiment 1.
