Abstract
The utility model discloses an angle measurement device for a joint. The angle measurement device comprises a central disc, a disc surface, an indicator rotary disc and grapping hooks, wherein a scale is formed on the disc surface; a minitype deep groove ball rolling bearing is arranged on the central disc; the disc surface is fixed at the front side of the central disc by a fastening member; the indicator rotary disc is arranged at the front side of the disc surface and passes through the disc surface to be connected with the minitype deep groove ball rolling bearing; a connection block is fixed at the back side of the disc surface; the grapping hooks are connected with the central disc by the fastening member; an indicator is also fixed on the indicator rotary disc; the connection block is also connected with a sliding rod; a connection sliding block is sleeved on the sliding rod; two symmetrical wing plates are also arranged on the angle measurement device. When the angle measurement device is used, two grapping hooks can clamp one end of the joint, so that the grapping hooks are rotated along with the rotation of the joint; and the angle measurement device is matched with the two grapping hooks, so that the torsion angle and the rotation angle of the joint can be easily measured, and the motion angle of the joint can be accurately described. The angle measurement device is of a simple structure, and is convenient to operate, high in use performance and low in cost.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments that is used for, particularly a kind of joint angles 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 influence therapeutic effect.Therefore, in measuring process, to reduce error as far as possible.
At present, for the angular surveying in joint, current measuring methods is ocular estimate and angle block gauge measurement method.And do not have 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 bigger.Angle block gauge is then powerless for the windup-degree in joint.Present clinical medical development requires increasingly highly to degree of accuracy, also impels each item 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
This utility model technical problem to be solved is the deficiency to prior art, provide a kind of rational in infrastructure, measure joint windup-degree measuring device accurately.
This utility model technical problem to be solved is to realize through following technical scheme.This utility model is a kind of joint angles measuring device, is characterized in: it comprises spider, card, pointer rotating disk and grapple; Card is provided with scale; Miniature zanjon ball rolling bearing is installed on spider, and card is fixed on the spider front side through securing member; The pointer rotating disk is located at the card front side and passes card and is connected with miniature zanjon ball rolling bearing; On the rear side of card, be fixed with contiguous block; Described grapple is 2, is symmetrical set, and grapple is connected with spider through securing member; On the pointer rotating disk, also be fixed with pointer; On contiguous block, also be connected with litter, on litter, be socketed with the connection slide block; It also is provided with 2 symmetrically arranged fins, and an end of fin links to each other with grapple respectively through securing member, the other end be connected the slide block connection.
The described securing member of this utility model can use in the existing standard spare applicable to the described securing member of this utility model.The optimal technical scheme of securing member is: the securing member that connects fin and grapple is preferably nylon spacer, cross pan head screw and nut.Fixedly the securing member of card and spider is preferably the cross sunk screw; Fixedly the securing member of grapple and spider is preferably cross sunk screw, pad and nylon spacer.
When this utility model uses; Can cross two grapples and clamp joint one end, reverse and rotate, can measure the windup-degree in joint easily through the scale and the pointer of this utility model along with the joint; Protractor through cooperating can be measured the anglec of rotation, thereby accurately describes the mobility in joint.Compared with prior art, this utility model joint angles measuring device is simple in structure, and is easy to operate, and serviceability is good, and cost is low, is a kind of ideal joint angles measuring device.
Description of drawings
Fig. 1 is a kind of structural representation of joint angles measuring device;
Fig. 2 is the partial schematic sectional view of joint angles measuring device;
Fig. 3 is the structural representation of grapple and litter.
The specific embodiment
Following with reference to accompanying drawing, further describe the concrete technical scheme of this utility model, so that those skilled in the art understands this utility model further, and do not constitute restriction to its right.
During enforcement, clamp an end in joint, keep pointed center line 0 graduation mark with grapple 4; Making the joint angles measuring device follow the joint reverses and rotates; Keep grapple 4 and joint to reverse synchronously during torsion knuckle, be used to indicate the rotation of the pointer 3 of angle along with the joint angles measuring device, pointer 3 is being with pointer rotating disk 2 to rotate; On card 1, read the joint windup-degree, thereby realize the measurement of windup-degree.The use of use level hornwork can easily obtain the windup-degree and the anglec of rotation in joint, for doctor's treatment provides range of motion foundation accurately.
