Description
technical field:
The present invention relates to neuro-surgery operation screw special clamper and using method thereof, belong to technical field of medical instruments.
background technology:
Brain comprises akrencephalon and diencephalon, and akrencephalon comprises left and right brain hemisphere.Akrencephalon is the major part of the higher nerve system of vertebrate brain, is made up of left and right two hemispheres, accounts for the overwhelming majority of brain, is controlled motion, sensigenous and realize the higher nervous center of higher brain.Vertebrate akrencephalon when embryo be neurocele head end thin-walled swell part, develop into cerebral hemispheres later, mainly comprise three parts such as cerebral cortex, cerebral medullary substance and basal nuclei.Cerebral cortex is overlayed on the grey matter on akrencephalon surface, is formed primarily of neuronic cell space.The medullary substance that the deep of cortex is formed by nerve fiber or white matter are formed.Have again grey matter agglomerate and basal nuclei in medullary substance, striatum is major part wherein.
When there is pathological changes in brain or skull is subject to wound, need to open skull in time, to treat lesion, at therapeutic process or when completing, need to fix a block plate or in order to connect impaired skull need to use Interal fixation time, be all often with Medical screw by Interal fixation on skull, this screw be fixed on spiral shell cutter head by screw by doctor, but this screw is very little after having sterilized together in company with spiral shell cutter, length only has 5mm, and diameter is only less than 2mm.Doctor has on rubber gloves on hand, operates very inconvenient, therefore affects procedure efficiency.
summary of the invention:
For the problems referred to above, the technical problem to be solved in the present invention is to provide a kind of neuro-surgery operation screw special clamper and using method thereof.
Neuro-surgery operation screw special clamper of the present invention and using method thereof, it comprises shell, the first stage clip, clamping plate, addendum cone shell, the second stage clip, button, silica gel piece and hole; Clamping plate are fixed on the bosom of shell by the first stage clip of both sides, clamping plate comprise train wheel bridge and lower plate, the two ends of train wheel bridge and lower plate connecting sewing are provided with addendum cone shell, addendum cone shell is connected with button, the second stage clip is provided with between addendum cone shell and button, the lower, transverse of train wheel bridge is evenly provided with several hole, under the upper lateral of clamping plate be provided with silica gel piece.
As preferably, described hole is semicircle orifice, and the opening of semi-circular hole contacts with silica gel piece.Better can coordinate pinching screw with silica gel piece, prevent Slipped bolt.
As preferably, the outer surface of described button is provided with several crisscross indentures.Increasing friction, preventing medical personnel when performing the operation, there is skidding in pressing button, affects procedure.
As preferably, the outer surface of described shell is provided with skid resistant course.Facilitate taking of medical personnel, not easily skid.
As preferably, described shell is transparent outer cover.See the state of screw time easy to use, the working condition of the first inner stage clip can also be found at any time, if stage clip has damage to change timely, do not affect procedure.
Using method of the present invention is: first carried out disinfection by screw, then with the button at hands pressing two ends, the addendum cone shell at two ends is made to extrude train wheel bridge and lower plate inwards, in the semi-circular hole that the screw disinfected loading one by one has outwards separately been sterilized by train wheel bridge and lower plate more, then release button by the first stage clip and silica gel piece by screws clamp, when operation needs to use screw, a hands catches shell, another hand-held electric screwdriver or manual spiral shell cutter, then by spiral shell cutter head alignment screw head, two end buttons are pressed with hands, the addendum cone shell at two ends is made to extrude train wheel bridge and lower plate inwards, train wheel bridge and lower plate are outwards separated, then spiral shell cutter is used just can to take off screw easily.
Beneficial effect of the present invention is: its novel structure, and medical personnel can be helped to take off the smaller screw of volume easily, and easy to operate, improves the procedure efficiency of doctor.
accompanying drawing illustrates:
For ease of illustrating, the present invention is described in detail by following concrete enforcement and accompanying drawing.
