Abstract
The utility model discloses a skull correction type traction apparatus, which comprises two bowed arms, two bowed handles, self-tapping screws and the like, wherein the two opposite bowed arms are connected with the two opposite bowed handles through movable shafts; the end parts of the bowed arms are provided with the self-tapping screws; telescopic rods with opposite thread direction are fixed on the end parts of the two bowed handles respectively; two opposite ends of the two telescopic rods are connected with each other through a sleeve nut with internal threads; and a planar correction plate is fixed on the movable shafts. Through the planar correction plate on the movable shafts, a traction bow plane can be parallel to a cervical vertebra coronal plane, so that large traction resultant force is obtained. The utility model has the advantages that: the skull correction traction apparatus has a simple structure, and is economical and practical.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to the traction apparatus of a kind of skull correction-type.
Background technology
Clinically, fracture-dislocation of cervical spine, cervical spinal injury disease, upper cervical spine deformity, dislocation etc. taking place, generally all adopts the skull traction apparatus to carry out traction therapeutic.A kind of " drilling-free skull tractor " disclosed as Chinese patent, this traction apparatus is arc tong-like, and locking pin is positioned at the caliper front end, and the caliper tail end has the jaw amount of opening to regulate bolt, locking pin can directly eject fixing hole on skull when screwing in, and fixed thereon.Though the existing relatively traction apparatus of this skull tractor has saved the trouble that fixing hole is beaten in boring, and is easy to operate.But can't guarantee the parallel relation of traction bow plane and cervical vertebra coronalplane, cause to form bigger traction and make a concerted effort.
Summary of the invention
The purpose of this utility model is the parallel relation that can't guarantee traction bow plane and cervical vertebra coronalplane that exists at existing skull tractor, the problem that the influence traction is made a concerted effort, provide a kind of traction bow plane that can make parallel, improve the purpose that traction is made a concerted effort with the cervical vertebra coronalplane.
The purpose of this utility model is achieved through the following technical solutions, this skull correction-type traction apparatus comprises bow-shaped arm, arc handle, tapping screw etc., described two relative bow-shaped arms arc handle relative with two connects by movable axis, the end of described bow-shaped arm is provided with tapping screw, each is fixing an expansion link that hand of spiral is opposite the end of described two arc handles, holding in opposite directions by a telescopic nut that has female thread of described two expansion links links to each other, and fixing a plane rectification plate on the described movable axis.
During use, by tapping screw traction apparatus is fixed on the skull, the plane rectification plate can guarantee to make traction bow plane and cervical vertebra coronalplane to be in parastate, and the nut by the rotary sleeve cartridge type drives the flexible of expansion link, reaches and regulates the purpose that bow-shaped arm clamps degree.
The beneficial effects of the utility model: by the plane rectification plate is set on movable axis, can make traction bow plane and cervical vertebra coronalplane be in parastate, make a concerted effort, have advantage simple in structure, economical and practical to obtain bigger traction.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is embodiment of the present utility model
Among the figure: 1, bow-shaped arm 2, arc handle 3, movable axis 4, tapping screw 5, expansion link 6, nut 7, plane rectification plate
The specific embodiment
As shown in Figure 1, this skull correction-type traction apparatus comprises bow-shaped arm 1, arc handle 2, tapping screw 3 etc., two relative bow-shaped arm 1 arc handles 2 relative with two connect by movable axis 3, the end of bow-shaped arm 1 is provided with tapping screw 4, each is fixing an expansion link 5 that hand of spiral is opposite the end of two arc handles 2, holding in opposite directions by a telescopic nut 6 that has female thread of two expansion links 5 links to each other, and fixing a plane rectification plate 7 on the movable axis 3.During use, by tapping screw 4 traction apparatus is fixed on the skull, plane rectification plate 7 can guarantee to make traction bow plane and cervical vertebra coronalplane to be in parastate, and the nut 6 by the rotary sleeve cartridge type drives the flexible of expansion links 5, reaches and regulates the purpose that bow-shaped arm 1 clamps degree.
