Abstract
The invention discloses a novel mastoid retractor which comprises a left traction handle, a right traction handle, a left traction head and a right traction head. The middles of the left and right traction handles are hinged together, and a tooth-shaped limiting structure is arranged between the left and right traction handles. A limiting structure locking structure is arranged on the left traction handle or the right traction handle. Poking claws are arranged on the left and right traction heads and are asymmetric. Dual-row scale marks for visually reading the distance between the left and right traction handles and the distance between the front ends of the traction heads are arranged on the limiting structure. In addition, the limiting structure locking structure is defined on the left traction handle or the right traction handle and cannot exceed the left and right traction handles in size. Due to the arrangement of the asymmetric poking claws, the problem of asymmetric traction of muscles of different depths can be solved, due to the arrangement of the dual-row scale marks, surgical operation quantization can be performed, and surgery is not performed only depending on doctor experience; the limiting structure locking structure is small, so that the novel mastoid retractor is small in occupied size and convenient to operate.
Description
Technical field
The invention belongs to neurosurgery medical apparatus and instruments, used in particularly a kind of neurosurgery microsurgical vascular decompression
Symmetry retracts the retractor of auricularis posterior meat and in particular to being a kind of new mastoid retractor.
Background technology
In neurosurgery microsurgical vascular decompression, because occipital bone turns to basis cranii direction, the difference of auricularis posterior meat thickness, mesh
Front conventional symmetrical mastoid retractor can not symmetrically retract muscle, and often the shallower side of muscle depth retracts
Overweight, and the deeper side of depth can not effectively retract, therefore need to design new retractor to meet the demand.
In addition, in existing mastoid retractor be not provided with scale more, the experience retracting the how flat doctor of size of size is carried out,
Doctor is had high demands, and perform the operation can not quantification treatment well, so that operation precision is affected, be therefore also required to existing
Retractor on setting scale with ensure retract size quantization.
And the latch-up structure of existing mastoid retractor is arranged on outside traction handle and larger, operate inconvenience during operation
Impact surgical field of view, it is therefore desirable for a kind of setting of little latch-up structure is solving to be asked a question.
The purpose of the present invention is that the nipple retractor for prior art can not symmetrically retract the different tissue of muscle thickness,
Can not will retract Size quantization, and the problems such as latch-up structure is larger, provide a kind of new mastoid retractor.
Content of the invention
Nipple retractor in order to overcome prior art can not symmetrically retract the different tissue of muscle thickness it is impossible to will retract
Size quantization, and the problems such as latch-up structure is larger, it is an object of the invention to provide a kind of new mastoid process that can solve the above problems
Retractor.
The purpose of the present invention is achieved through the following technical solutions：
A kind of new mastoid retractor, including left traction handle, right traction handle, left traction head, right traction head, left and right retracts handle
Middle hinged, position limiting structure is set between the two, left traction handle or right traction handle arrange position limiting structure latch-up structure；
Described left and right retracts setting pusher dog on head it is characterised in that described left and right retracts the pusher dog arranging asymmetry on head, and homonymy leads
Pusher dog in beginning is equivalently-sized, and the pusher dog size that offside retracts on head is different.The heteropleural pusher dog of asymmetry can retract not
With the Musclar layer of depth, retract effect good.
Further, described pusher dog is set to non-integral structure with retracting head, and pusher dog can arrange different size, pusher dog and traction
On head, corresponding primary screw hole is set, by small screw, pusher dog is arranged on traction head.Situation according to patient during operation
Select the pusher dog of suitable dimension.Non-integral setting can select different sizes according to the situation of patient, only needs to change during use
Pusher dog can be easy to use it is not necessary to replace whole device.
Further, described pusher dog is set to be easy to push aside the arcuate structure of muscular tissue, and the setting of its upper end connects with retracting head
The vertical section connecing.Arc setting is easier to push muscle aside, and tissue will not be damaged.
Further, described position limiting structure is provided for intuitively reading left and right and retracts before distance and left and right between handle retract head
The double scale of end distance.Double scale is calculated according to the shape of retractor and is arranged scale, and the setting of this scale is permissible
Get information about left and right and retract handle and the distance of left and right traction head front end, in operation, allow traction concrete more directly perceived, can be effective
Save operating time.
Further, described position limiting structure one end connects left traction handle or right traction handle, the other end stretch into right traction handle or
Person is left to retract in the hole inside handle；Described position limiting structure latch-up structure be limited to left traction handle or right traction handle on and size not
Retract the structure of handle beyond left and right；
Described position limiting structure latch-up structure includes being arranged at the left chute retracting on handle or right traction handle, setting in chute
Slide construction, described slide construction includes the insertion plate being inserted in limiting structure both sides of the little square plate in upper end and lower end, in little square plate
Setting locking piece.The setting of this position limiting structure latch-up structure can effective save space, prevent operation doctor is interfered.
Further, described locking piece is including the screw being arranged in little square plate and screw rod corresponding with screw, on screw rod
Setting nut.
Or, locking piece is that square in the hole setting carries tooth covered structure, described including the square opening being arranged in little square plate
Position limiting structure is band tooth position limiting structure, and the described tooth with tooth covered structure can be combined with the tooth of position limiting structure, reaches locking spacing
The purpose of structure.Further, on described covered structure with holes, setting connects the swingle of little square plate, and covered structure with holes also includes
Lower section dentalation and upper plate structure, swingle is arranged in slab construction.
Further, described traction head is separately positioned in retracting handle, hinged between two.
Or it is separately positioned in retracting handle to retract head, retracts handle front end and arranges toothed cylindrical section, retracts the setting of head rear end
The corresponding patchhole for inserting cylindrical section.
Further, homonymy retracts and arranges 3-8 pusher dog on head.
Further, described retractor adopts medical metal material.
The size of retractor of the present invention and prior art comparable dimensions, do not do big improvement.
Compared with prior art, in the new mastoid retractor of the present invention, the setting of the pusher dog of heteropleural asymmetry can retract
The different Musclar layer of thickness, and the pusher dog of suitable dimension can be rotated according to Musclar layer thickness；In addition the setting of double scale
Forward-and-rearward distance can intuitively be connected, increase the accuracy retracting distance；The setting of little position limiting structure latch-up structure can
Taken up space with effective apparatus that reduces, and then reduced the interference to operator in operation process.
