Abstract
The utility model provides an improved skull lock which belongs to medical equipment. The skull lock comprises a support rod; a lower tablet is fixed at the lower end of a threaded rod integrated with the support rod; a round-shaped upper tablet is arranged in the middle of the threaded rod through screw threads; and the lower tablet is in the shape of a slip. The skull lock has the advantages that the area of the lower tablet which is in the shape of a slip is small, so that the inner side surface is smaller, thereby effectively reducing the generation of the epidural hematoma.
Description
Technical field
This utility model provides a kind of medical device, especially a kind of skull lock.
Background technology
Skull lock is used for the fixing of bone lobe after the operation of opening cranium.The structure of existing skull lock is, a pole is arranged, and is fixed with down sheet with the lower end of pole all-in-one-piece threaded rod, the threaded rod middle part by screw thread be equipped with circle last slice.Because the shape of sheet also is circular down, area is big, thereby it is also bigger to occupy the inboard area of skull, causes epidural hematoma easily.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of improved skull lock, with the generation of effective minimizing epidural hematoma problem.
This utility model is achieved in that a kind of improved skull lock, and it has pole, is fixed with down sheet with the lower end of pole all-in-one-piece threaded rod, the threaded rod middle part by screw thread be equipped with circular last slice, the described sheet that descends is strip of sheet.
Adopt the skull lock of said structure, because sheet is strip of sheet down, area is little, thereby it is also less to occupy the inboard area of skull, thereby has effectively reduced the generation of epidural hematoma problem.
Description of drawings
Fig. 1 is the sketch map of this utility model structure.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates structure of the present utility model.
As shown in drawings, a kind of improved skull of this utility model lock, it has pole 1, is fixed with down sheet 5 with the lower end of pole all-in-one-piece threaded rod 11, the threaded rod middle part by screw thread be equipped with circular last slice 4, the described sheet 5 that descends is strip of sheet.
The installation and application of this skull lock and existing skull are phase-locked together.Promptly earlier will at least three on the poles following be placed on the skull inboard, restore cranial bone flap, after confirming down sheet and skull fully contacting, rotation last slice contacts the skull outer surface until last slice; To screw device 2 again and pass pole, make in two holes that have in two pawls, 3 reeves last slice that screw the device lower end, and rotate and screw device, drive last slice locking; Above last slice, cut off pole with cutting off pincers at last.
The same with existing skull lock, following sheet two ends are upturned, and the edges at two ends indentation.
