Description
Technical field
This utility model relates to a kind of spine nail holder structure.
Background technology
When being used for the treatment of spinal disease clinically, often need to implant multiple pedicle screw in spinal column both sides, then with longitudinal spinal rods the pedicle screw of the same side coupled together and form stable straightening mechanism.But for complicated diseases such as scoliosis, because the spinal column of patient itself is not straight, the pedicle screw implanted is not point-blank, refill after needing according to scoliosis situation, longitudinal spinal rods to be curved and receive pedicle of vertebral arch screw and nail on, it is very inconvenient to operate, and easily cause weaken after longitudinal spinal rods distortion, and fixing undesirable, affect corrective therapy effect.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of spine nail holder structure, has easy and simple to handle, and the suitability is wide, and the advantage that stability is strong, can effectively meet various clinical demand.
This utility model solves the technical scheme that its technical problem adopts:
A kind of spine nail holder structure, comprises the Connection Block 30 of a U-shaped seat 20 of nut assembly 10, one and attaching nut's assembly 10 and U-shaped seat 20; This nut assembly 10 has the screwed hole 11 of up/down perforation; U-type groove is formed, this U-type groove 20 opening upwards and the groove direction of U-type groove is vertical with the axis of screwed hole 11 in this U-shaped seat 20; This nut assembly 10 is arranged with Connection Block about 30, Connection Block 30 and U-type groove about 20 fixed and arranged, and this Connection Block 30 has the through hole of the corresponding screwed hole 11 of up/down perforation.
In one embodiment: also comprise the rotation seat 40 that is fixed in Connection Block 30, this rotation seat 40 is rotationally connected with described nut assembly 10, and rotation seat 40 and nut assembly 10 cooperatively interact and rotate to make U-shaped seat 20 with nut assembly 10 for axle rotates.
In one embodiment: the part outstanding formation one ring-type card edge downwards of described nut assembly 10 diapire, described rotation seat 40 upper wall is arranged with an annular groove, this ring-type card taps in annular groove along adapter, and this ring-type card rotates along cooperatively interacting with this annular groove, rotate to make nut assembly 10 and rotation seat 40 cooperatively interact.
In one embodiment: the shape adaptation of described rotation seat 40 and nut assembly 10.
In one embodiment: described U-type groove inwall is provided with the detent projection structure that parallel interval is arranged.
In one embodiment: described Connection Block 30 is one-body molded with U-shaped seat 20.
The technical program is compared with background technology, and its tool has the following advantages:
1. spine nail holder structure of the present utility model adopts two open design, the adaptive attaching pedicle screw of screwed hole, and the longitudinal spinal rods of the adaptive attaching of U-shaped seat, can effectively pedicle screw and longitudinal spinal rods be fitted together, structure is simple, easy to operate.
2. spine nail holder structure of the present utility model has rotation seat, U-shaped seat energy opposing nut assembly rotates, conveniently can adjust the angle of U-type groove, like this, even if patient's spinal column does not directly cause multiple pedicle screw cannot be on the same line, process is not needed to curve longitudinal spinal rods yet, directly can rotate each U-shaped seat successively, regulate and the groove direction of U-type groove is located along the same line, attaching can enter longitudinal spinal rods, easy to use, swift to operate, and there is not deformation in longitudinal spinal rods, intensity is better, stability is stronger, and corrective therapy effect is unaffected.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is spine nail holder structure overall appearance schematic diagram of the present utility model.
Reference numeral: nut assembly 10, screwed hole 11; U-shaped seat 20, Connection Block 30, rotation seat 40.
Detailed description of the invention
Content of the present utility model is illustrated below by embodiment:
Please refer to Fig. 1, a kind of spine nail holder structure, comprise the Connection Block 30 of a U-shaped seat 20 of nut assembly 10, one and attaching nut's assembly 10 and U-shaped seat 20; This nut assembly 10 has the screwed hole 11 of up/down perforation; U-type groove is formed, this U-type groove 20 opening upwards and the groove direction of U-type groove is vertical with the axis of screwed hole 11 in this U-shaped seat 20; This nut assembly 10 is arranged with Connection Block about 30, Connection Block 30 is one-body molded and left and right fixed and arranged with U-shaped seat 20, and this Connection Block 30 has the through hole of the corresponding screwed hole 11 of up/down perforation, during use, pedicle screw can pass this screwed hole 11 with through hole to be installed on described spine nail holder structure, longitudinal spinal rods attaching enters in U-type groove, and pedicle screw is mutually vertical with longitudinal spinal rods.
Among the present embodiment, also comprise the rotation seat 40 that is fixed in Connection Block 30, this rotation seat 40 is rotationally connected with described nut assembly 10, concrete structure is such as, the part outstanding formation one ring-type card edge downwards of described nut assembly 10 diapire, described rotation seat 40 upper wall is arranged with an annular groove, this ring-type card taps in annular groove along adapter, and this ring-type card rotates along cooperatively interacting with this annular groove, rotate to make nut assembly 10 and rotation seat 40 cooperatively interact, make U-shaped seat 20 can with nut assembly 10 for axle rotate, like this, conveniently can regulate the angle of U-type groove.
Among the present embodiment, the shape adaptation of described rotation seat 40 and nut assembly 10, profile is more unanimously attractive in appearance.
Best, described U-type groove 20 inwall is provided with the detent projection structure that parallel interval is arranged, like this, longitudinal spinal rods can firmly be fixed in U-type groove, not easily slippage.
This utility model onsite application mode is as follows:
During the actual use of spine nail holder structure of the present utility model, first matching used pedicle screw is loaded screwed hole to be installed on described spine nail holder structure, again pedicle screw is implanted pedicle of vertebral arch, according to the degree of crook of vertebra, rotate the position regulating U-shaped seat, the groove direction of multiple U-type groove is located along the same line, like this, longitudinal spinal rods curves can attaching enter in U-type groove without the need to process, completes installation process.
The above, be only this utility model preferred embodiment, therefore the scope that this utility model implements can not be limited according to this, the equivalence namely done according to this utility model the scope of the claims and description change with modify, all should still belong in scope that this utility model contains.
