Utility model content
This utility model provides a kind of broken nail nail-fetching device, by adjusting the angle of nail-fetching device, thus realize that patient body difficulty gets nail position get nail operation.
This utility model adopts following technical scheme:
A kind of broken nail nail-fetching device, comprise support, support is L-type, described support is from top to bottom provided with successively and gets nail frame, train wheel bridge and rack, described get nail frame be circular arc, get nail frame and be provided with the first groove, the slide block of circular arc is provided with in first groove, slide block side is provided with the first clamp device, be provided with through slide block and get nail axle, get nail axle bottom and be provided with two symmetrical coneheads, conehead outside is provided with clamp nut, support is provided with chute, train wheel bridge one end is arranged in chute, train wheel bridge can slide to adjust height in chute, and be provided with the second clamp device, train wheel bridge offers action pane, described rack one end by bearing pin and support hinged, rack and support hinged end are also provided with the 3rd clamp device, angle between 3rd clamp device fixed placement frame and support, described rack is also provided with arc-shaped depression portion.
Described nail frame side of getting is provided with the second groove, and the first clamp device is arranged in the second groove.Preferably, described first clamp device and the second clamp device are fastening bolt.
Described 3rd clamp device can select ratchet and detent mechanism, and ratchet and pawl arrangement can realize the equal angular rotation of rack, and after rotating, ratchet can fixed ratchet wheel position, thus the angle between fixed placement frame and support.
Conveniently operate, get nail axle top and be provided with handle.In addition, get nail axle with between slide block for being threaded, the height of turning handle and adjustable two conehead.
This utility model realizes by following mode of operation: be first placed in rack recess by patient's lesions position, by observing the position need getting nail, adjustment slide block makes to get nail axle aligning need get nail position, coordinate adjustment by adjustment rack with the angle between support when adjustment slide block, the conehead finally got on nail axle is aimed at and need get nail position.After having adjusted, mobile train wheel bridge is also locked the second clamp device and is made it clamp the healthy position of patient, in order to avoid health moves.Then turning handle makes to get nail axle near getting nail position, clamps broken nail, and is fixed in the middle of two coneheads by clamp nut by broken nail, finally, screw handle and taken out by broken nail by the space of two coneheads.
Advantage of the present utility model and beneficial effect are:
1, this utility model adopt circular arc get nail frame, get nail axle and realize the operation of different angles by slide block getting nail frame slides, simultaneously, rack is hinged, the angle adjustment of patient part can be realized, get nail frame and rack coordinate adjustment, thus realize patient difficulty get nail position get nail operation, it also avoid the adjustment to patient body simultaneously, alleviate the misery of patient.
2, this utility model rack is provided with recess, coordinates train wheel bridge to fix sufferer position, in order to avoid lesions position is movable, nail operation is got in impact.
