Specific embodiment
In order to which technical problem to be solved in the utility model, technical solution and beneficial effect is more clearly understood, with
Lower combination accompanying drawings and embodiments, the present invention will be further described in detail.It should be appreciated that specific reality described herein
It applies example to be only used to explain the utility model, is not used to limit the utility model.
Also referring to Fig. 1 to Fig. 8, now unilateral nail holding device provided by the embodiment of the utility model is illustrated.It is unilateral
Nail holding device, comprising:
Holding rod 10, lower end are equipped with the holding tank 11 for accommodating the single side plate 40 of pedicle screw；
Stay hook 20 is connect with holding rod 10, positioned at 11 inner back side of holding tank and is used for and single 40 rear side of side plate
41 clasp joint of fixation hole；And
Separating mechanism 30 is set between holding rod 10 and stay hook 20, for pushing stay hook 20 from the bottom of holding tank 11
Portion exits.
Compared with prior art, the utility model unilateral side nail holding device, in use, the single side plate 40 of pedicle screw is inserted
Enter in holding tank 11, then using 41 clasp joint of fixation hole of 40 rear side of stay hook 20 and single side plate, single side plate 40 is limited
In holding tank 11, the clamping of pedicle screw is realized.After pedicle screw is put into predetermined position, pushed away by separating mechanism 30
Dynamic stay hook 20 is exited from fixation hole 41, releases limit of the stay hook 20 to single side plate 40, so that single side plate 40 is from folder
It holds in slot 11 and skids off.The utility model unilateral side nail holding device can realize the clamping to pedicle screw using single side plate 40, subtract
Lack to blocking at the top of pedicle screw, has been convenient for subsequent operation.
