Description
Technical field
The invention belongs to medical instruments fields, in particular to cerebral surgery operation retractor.
Background technique
For retracting the instrument of brain tissue when existing cerebral surgery operation, it is mainly used for when intracerebral hematoma is removed or intracerebral is swollen
When tumor, intraventricular tumor excision, brain tissue, exposure hemotoncus or tumor tissues are retracted.Currently, extensive when domestic and international cerebral surgery operation
Application is mostly the self-maintaining retractor of flexible axle, and such retractor requires height to operating bed when in use, installs complicated, time-consuming, valence
Money is expensive, and occupied space is big, simultaneously as the wound shape of different patient with operation is different, generally requires traction into round, square
Shape or other irregular shapes, at this point, such retractor is difficult to meet actual demand.And for as being removed intracerebral hematoma
Simple operation, general using formula retractor is retracted manually, this kind of retractor mainly by annulus and is slidably connected on annulus
Traction portion for retracting wound is constituted, and when in use, either which kind of wound requires individually one by one to move traction portion
It is dynamic, and then adjust out suitable wound.
Summary of the invention
The invention is intended to provide cerebral surgery operation retractor, to solve existing hand retractor when retracting wound,
It needs individually one by one to move traction portion, and then leads to cumbersome problem.
Cerebral surgery operation retractor in this programme, including annulus, more connecting rods and Duo Gen fixed link, fixed link and company
Extension bar is spaced setting two-by-two, and more fixed links are uniformly distributed and are fixedly connected on the outer wall of annulus, and the more connecting rods are hinged on
On the outer wall of annulus；It is rotatably connected to rotating bar in the more connecting rods and fixed link, is fixedly connected in rotating bar
Sprocket wheel, multiple sprocket wheels are connected by chain drive；Gear is additionally provided in the rotating bar connecting with connecting rod；The annulus it is upper
End face is evenly equipped with fixed block, and fixed block is equipped with threaded hole, and the axis of threaded hole passes through the axle center of annulus, and threaded hole internal screw thread connects
It is connected to slide bar, one end of slide bar is equipped with screw thread, and the other end of slide bar is equipped with helical tooth, and slide bar is engaged by helical tooth with gear,
Slide bar is threadedly coupled by screw thread with threaded hole；Slide bar sets threaded one end and is fixedly connected with traction portion.
The working principle of this programme and its utility model has the advantages that in use, when wound traction need regular shape when, rotation rotation
Bar, rotating bar drive chain drive, and then drive all rotating bar rotations, and rotating bar rotation driven gear rotation, gear turns
Dynamic band moving slide-bar rotates, and slide bar rotation drives the sliding of traction portion, can be realized by the positive and negative rotation of rotating bar to sliding side, traction portion
To control, and then realize to wound retract size control.But when wound traction needs strip, rotation a direction is opposite
Connecting rod, so that the sprocket wheel and chain in the rotating bar connecting with the connecting rod are detached from, it is therefore prevented that the traction portion of the position is mobile,
And then the traction strip of wound can be made.When wound traction is in irregular shape, it is rotatablely connected bar, so that connect with connecting rod
Whole sprocket wheels and chain in rotating bar are detached from, then the rotation of single operation slide bar, and then the wound for controlling some position retracts, can
Irregular shape is retracted to wound.It can be operated simultaneously all, partially or individually using the retractor in this programme
Traction portion is mobile, easy to operate, usability is strong.
Further, it is fixedly connected with horizontally disposed cross bar on the annulus, is fixedly connected with and is vertically arranged on cross bar
The bottom of vertical bar, vertical bar is fixedly connected with pedestal.By the setting of cross bar, vertical bar and pedestal, convenient for placing retractor.
Further, the cross bar and vertical bar are telescopic rod.Telescopic rod is set by cross bar and vertical bar, it can be to traction portion
Position is adjusted, and is more advantageous to the progress of operation.
Further, the pedestal is equipped with the card slot for connecting operating bed.By the way that card slot is arranged, being convenient for can by retractor
Dismantling connection is on operating bed, using more convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of cerebral surgery operation retractor of the present invention；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
It is further described below by specific embodiment:
Appended drawing reference in Figure of description include: rotating bar 1, gear 2, fixed block 3, slide bar 4, traction portion 5, annulus 6,
Cross bar 7, helical tooth 8, chain 9, pedestal 10, card slot 11, connecting rod 12, sprocket wheel 13.Embodiment is basic as shown in attached drawing 1~2: brain
Surgical retractors, including annulus 6, more connecting rods 12 and Duo Gen fixed link are fixedly connected on annulus 6 horizontally disposed
Cross bar 7 is fixedly connected with the vertical bar being vertically arranged on cross bar 7, and cross bar 7 and vertical bar are telescopic rod, and the bottom of vertical bar is fixed
It is connected with pedestal 10, pedestal 10 is equipped with the card slot 11 for connecting operating bed；Fixed link and connecting rod 12 are spaced (i.e. solid two-by-two
