Description
Technical field
The present invention relates to a kind of bone tractor, particularly a kind of adjustable middle part bone tractor and method for designing belong to medical instruments field.
Background technology
Skull fixed middle part bone tractor (Mid-face Distraction OsteogenesisDevices) is also referred to as the external fixation skull tractor sometimes.To upper jaw bone deficiency of development patient, existing external fixation skull tractor can only be after Le Fort cuts bone, with the part upper jaw bone section that sections to front haulage, to recover its normal face type.To face middle part bone fracture back depression patient, the bone section that can only fracture to front haulage resets it.To half side facial atrophy patient, can only be with part face middle part bone piece to front haulage, to recover its face type as far as possible.But still have most of patient to need part face middle part bone section is drawn to the side, to recover the richness of side face type.For example, to half side facial atrophy patient, we need is not only traction element face middle part bone section forward, also need part bone section be drawn to the side simultaneously.And for cheekbone closure, depressed fracture patient, need simultaneously forward too, draw to the side, the cheekbone of displacement fracture is accurately resetted.And existing the single of external fixation skull tractor can meet clinical needs to front haulage far from.And draw, can not appear in the newspapers as yet to the external fixation skull tractor of front haulage simultaneously in the relevant side of different angles of realizing.
Summary of the invention
The objective of the invention is: a kind of adjustable middle part bone tractor and method for designing are provided; It can be in the time of front haulage, can also realize the side traction of different angles; It resets to the side of different angles for the midfacial fracture section, or recovers or rebuild its face shape a kind of armarium that improves is provided through the side traction of face middle part bone section.
Technical scheme of the present invention is: design a kind of adjustable middle part bone tractor and method for designing; Which comprises at least support, skull staple, traction titanium nail, traction fiber, it is characterized in that: its support is fixedly connected adjustable link by the camber link that has draw-in groove through removable connector and constitutes; Camber link middle part is fixedly connected with the support contiguous block through removable connector; The camber link can be fixed one or a plurality of adjustable link as required, is connected with traction screw and pull nut on the adjustable link.
Described adjustable link is to be connected and composed by vertical links contiguous block and vertical links vertical fixing, and the vertical links contiguous block is fixed-site connection arbitrarily on the draw-in groove of camber link.
Described support contiguous block is a demountable structure, and its length specification can be selected.
Described vertical links vertically is arranged with a row can pass the square hole of traction screw, through a plurality of traction screws of pegging graft of the square hole on the vertical links.
Described support both sides are connected with the skull staple, and the skull staple of support both sides is fixed on the camber link on patient's the skull.
Be connected with a plurality of traction screws on the vertical links, facing to points different in the middle part of patient's face, fixing many pieces of traction titaniums nails, the traction titanium is followed closely through traction fiber from being connected to the different traction screws on the different vertical connecting rod between jaw.
Described support both sides are connected with the skull staple, and the skull staple of support both sides is fixed on the camber link on patient's the skull; The vertical links vertical fixing is connected on the vertical links contiguous block, and the vertical links contiguous block can any fixed-site connect on the draw-in groove of camber link, and vertical links can be fixed in optional position from left to right, patient's face the place ahead like this; Vertical links vertically is arranged with the square hole that a row can pass traction screw, and traction screw can be loaded on wherein arbitrary square hole, so just can realize optional position from top to bottom, patient's face middle part; Had vertical links and traction screw laterally with longitudinally moving arbitrarily, just can apply pull strength through traction fiber to bone in the middle part of patient's the face from the optional position at patient's face middle part, said traction fiber is an oral cavity ligation silk commonly used; The camber link can be fixed one or more adjustable link as required; On the vertical links a plurality of traction screws can be installed; Facing to the different point in patient's face middle part; Can push up fixing many pieces of traction titanium nails altogether, traction titanium nail from being connected to different traction screws on the different vertical connecting rod between jaw, so just can be implemented multiple spot, multidirectional traction to patient's face middle part bone through traction fiber; In distraction procedure, can adjust the pull nut of certain traction screw at any time, change certain any hauling speed, realize adjusting angle while draw.
Characteristics of the present invention are: the vertical vertical links contiguous block of adjustable link can any fixed-site connect on the draw-in groove of camber link; Can guarantee like this in side when traction that needs different angles; Vertical connecting can be adjusted to suitable position, side, realizes the side traction of different angles through perpendicular traction screw; Vertical links vertically is arranged with square hole that a row can pass traction screw can guarantee on the one hand traction screw adjustment position arbitrarily on above-below direction; To realize the traction of differing heights face middle part bone section; Can guarantee that on the other hand traction screw passes through, and avoids traction screw to be positioned at vertical connecting one side, when applying pull strength, causes vertical connecting torsion phenomenon to occur in the middle of vertical connecting; The camber link can be fixed one or more adjustable link as required, realizes the adjustment angle while drawing; The camber link that has draw-in groove is basic consistent with people's facial appearance radian, can guarantee that vertical connecting moves to the optional position along draw-in groove, realizes the side traction of different angles; Detachable support contiguous block satisfies the patient's of different skull width demand through changing the support contiguous block of different length.Through such scheme, can satisfy the reparation requirement of patient's face to greatest extent, reach the target of recovering the normal face of patient.
Description of drawings
Below in conjunction with accompanying drawing and instantiation the present invention is described further:
