Abstract
The utility model relates to a joint angle measuring device. The device comprises a dial, a washer, a magnifying lens, a pointer, a measurer upper block, a measurer lower block, pull rod antennas and a screw; the dial is arranged on the measurer lower block; the measurer lower block is supported below the measurer upper block by the washer; the washer is fixed with the measurer upper block by the screw; the measurer upper block and the measurer lower block rotate relatively; the measurer upper block is provided with a reading hole; the pointer is arranged at the bottom of the reading hole; the magnifying lens is arranged at the upper part of the reading hole; two pull rod antennas are respectively arranged on the measurer upper block and the measurer lower block; and the center line of the pull rod antenna arranged on the measurer upper block and the projection of the pointer are positioned on the same straight line. When in use, the joint angle measuring device can point at both ends of a joint by the two pull rod antennas and rotates along with the rotation of the joint, so that the rotation angle of the joint can be easily measured. The device disclosed by the utility model has a simple structure, is convenient to operate, has excellent use performance and is low in cost.
Description
Technical field
This utility model relates to a kind of for medical apparatus and instruments, particularly a kind of joint angle measuring device.
Background technology
In curative activity, to measure inspection and be absolutely necessary, the error of measurement result is difficult to avoid, and the error that measurement result is brought will directly affect therapeutic effect.Therefore, to reduce error in measuring process as far as possible.
At present, for the angular surveying in joint, existing measuring method is ocular estimate and angle block gauge measurement method.And there is no a special-purpose angular surveying instrument.Therefore ocular estimate can only be used for rough calculating or qualitative examination because the error that exists is larger.And common angle block gauge is inadequate for the rotation angle measurement precision in joint.Present clinical medical development is more and more higher to the requirement of degree of accuracy, also impels every result of clinical detection digitized, precision and standardization more, describes also requiring necessary degree of accuracy for the functional status in joint.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provide a kind of rational in infrastructure, easy to use, measure joint angle measuring device accurately.
Technical problem to be solved in the utility model is to realize by following technical scheme.This utility model is a kind of joint angle measuring device, is characterized in: this device comprises graduated disc, pad, magnifier, pointer, piece on measuring device, piece under measuring device, collapsible mast and screw; Graduated disc is arranged under measuring device on piece; Pad is supported on piece below on measuring device with piece under measuring device, and pad is fixed by piece on screw and measuring device, relatively rotates between piece under piece and measuring device on measuring device; On measuring device, piece is provided with the reading hole, and pointer is arranged on bottom, reading hole, and magnifier is arranged on top, reading hole; 2 collapsible mast are arranged on respectively on measuring device under piece and measuring device on piece, being projected on the same straight line of the centrage of the collapsible mast of installing on piece on measuring device and pointer.
In joint angle measuring device described in the utility model: described collapsible mast is preferably the Telescopic handle antenna.
In joint angle measuring device described in the utility model: described screw is preferably Cross Recess Head Screw.
When this utility model device uses, can point to respectively the two ends, joint by 2 collapsible mast, the rotating tension bar antenna, drive on measuring device relatively rotating of piece under piece and measuring device, thereby realize relatively rotating of graduated disc, read angle on graduated disc by magnifier, measure on measuring device the relative rotation angle of piece under piece and measuring device, namely measure the anglec of rotation in joint, thereby accurately describe the mobility in joint.
Compared with prior art, this utility model joint angle measuring device is simple in structure, and is easy to operate, and serviceability is good, and cost is low, is a kind of desirable joint angle measuring device.
Description of drawings
Fig. 1 is a kind of sectional structure schematic diagram of this utility model device;
Fig. 2 is a kind of contour structures schematic diagram of this utility model device.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands this utility model further, and do not consist of its Copyright law.
During enforcement, with an arthrotropic end of collapsible mast 8 fingers, another root collapsible mast 8 arthrotropic other ends of finger, make joint angle measuring device follow the joint rotation and rotate, keep two collapsible mast 8 and joint rotary synchronous during rotary joint, pointer 5 is fixed on measuring device on piece 6 relatively, graduated disc 1 is fixed under measuring device on piece 7 relatively, the relatively rotating of piece 7 under piece 6 and measuring device on measuring device, see through magnifier 4 and read angle on the graduated disc of pointer indication, thereby realize the measurement of the anglec of rotation.For doctor's treatment provides range of motion foundation accurately.
Embodiment 3, and in the described joint angle measuring device of embodiment 1 or 2: described screw 2 is Cross Recess Head Screw.
