Description
Technical field
This utility model relates to neurosurgery equipment technical field, especially a kind of retractor.
Background technology
Usually need when neurosurgery row skull or spinal operation to retract skin and muscular tissue, conventional is a kind of retractor utilizing lever principle to make, cumulative volume occupied during tractive is large, visual area when impact operation is carried out exposes, in neurosurgery process, good visual area exposes and can be described as one of key that whole successful surgery carries out, the one side improving visual area exposure depends on the size of tractive opening, also relevant with shared volume during retractor tractive on the other hand, the size of retractor had both affected the operation of operation, also the exposure of visual area can be disturbed, reduce retractor volume during operation, visual area can be increased expose, reduce operation risk.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, provides a kind of connection-rod linkage formula neurosurgery retractor, under the prerequisite not reducing surgical field of view, reduces the space that operating equipment takies, and is conducive to reducing operation risk.
The technical solution adopted in the utility model is: provide connection-rod linkage formula neurosurgery retractor, and comprise two driving levers, carriages being symmetrical arranged in herringbone, the upper end of two driving levers is all provided with pusher dog; The lower end of two driving levers is respectively rotationally connected by a rotating shaft and carriage, and the bottom of two driving levers is all hinged with a connecting rod; Two connecting rods are symmetrical arranged and free end is hinged; The hinged place of two connecting rods is also hinged with positioning screw at vertical direction; The bottom of positioning screw is placed in the directive slide track in carriage; Directive slide track in the vertical direction has annular through-hole; Regulating wheel is provided with in annular through-hole; Regulating wheel is threaded with positioning screw.
Further optimization the technical program, each driving lever of connection-rod linkage formula neurosurgery retractor includes the sleeve pipe of two socket cooperations, and two sleeve pipes are by screw fastening.
Compared with traditional neurosurgery retractor, adopt technique scheme, the beneficial effects of the utility model are:
1, traditional neurosurgery retractor all adopts the arm of force and driving lever lever construction arranged in a crossed manner, and this utility model is by two connecting rods and two driving lever composition four-bar linkage structures, the angle of two driving levers is adjusted by screw rod, the rear portion of carriage no longer arranges lever arm of force, this reduces the space that operating equipment takies, and can not surgical field of view be reduced.
2, rotate regulating wheel, namely can pull two connecting rods by drive screw, thus change the angle of two driving levers, simple to operate, the mode of rotating regulating wheel to be exerted pressure controllable precise more by staff than traditional retractor.
3, the pusher dog of traditional retractor and driving lever are fixed by card article, and this utility model two pusher dogs and driving lever are directly fixed, and not easily loosen, and the position of pusher dog can by the length adjustment of adjustment driving lever, and adjusting range is large, firm and durable.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
As shown in Figure 1-2, connection-rod linkage formula neurosurgery retractor, comprise be symmetrical arranged in herringbone two driving levers 1, carriage 2, two driving levers 1 upper end pusher dog 3 is all installed; The lower end of two driving levers 1 is respectively rotationally connected by a rotating shaft 4 and carriage 2, and the bottom of two driving levers 1 is all hinged with a connecting rod 5; Two connecting rods 5 are symmetrical arranged and free end is hinged; The hinged place of two connecting rods 5 is also hinged with positioning screw 6 at vertical direction; The bottom of positioning screw 6 is placed in the directive slide track 7 in carriage 2; Directive slide track 7 in the vertical direction has annular through-hole 8; Regulating wheel 9 is provided with in annular through-hole 8; Regulating wheel 9 is threaded with positioning screw 6; Sleeve pipe 10, two sleeve pipes 10 that each driving lever 1 includes two socket cooperations are fastening by screw 11.
In use, two arcuate flanks 12 of user hand-held supports frame 2, then (unclasp screw 11 according to the length of the length adjustment driving lever 1 of tissue cut, regulate the socket amount of two sleeve pipes 10, then screw 11 is tightened), then two pusher dogs 3 are inserted tissue cut; The position of the vertical direction of regulating wheel 9 is limited in annular through-hole 8, rotate regulating wheel 9(in an initial condition, two pusher dogs 3 are in closure state) positioning screw 6 can be pulled to bottom offset, the quadric chain of two connecting rods 5 and two driving lever 1 compositions easily swings in the horizontal direction, the effect of directive slide track 7 is that restriction positioning screw 6 can only within it move, and prevents the swing of horizontal direction.Positioning screw 6 pulls the free end of two connecting rods 5 to bottom offset, struts two driving levers 1, both angles is increased, thus makes to retract tissue cut.
