Embodiment 1

[0035] This embodiment provides a distance measuring device, such as figure 1 as shown,

[0036] One side of the scale base 1 has an installation space for installing the lifting platform 2 and the transmission mechanism 4,

[0037] The lifting platform 2 is provided with a chute along its length direction, and a straight guide groove 21 is provided on one side wall of the chute, and gear grooves are provided on the two end surfaces of the lifting platform 2 in the length direction;

[0038] A scale 3 is provided in the chute of the lifting platform 2, which can move to any position in the chute along the chute. One end of the scale 3 is formed with a slide block, and a through hole is opened on the slide block. The through hole is preferably a screw hole. The fastener 5 passes through the guide groove 21 to detachably fix the scale 3 in the chute. The fastener 5 is preferably a screw. The lifting platform 2 is also provided with a positioning part for determining the specifi...

Abstract

The invention discloses a distance measuring device. The device includes a standard ruler base, a lifting platform, standard rulers and a transmission mechanism; one side of the standard ruler base is provided with an installation space, the lifting platform is provided with sliding grooves in the length direction, the wall surface of one side of each sliding groove is provided with a straight-line-shaped guide groove, and two end faces, in the length direction, of the lifting platform are provided with gear grooves, the standard rulers are arranged in the sliding grooves and can move to any positions in the sliding grooves along the sliding grooves, the transmission mechanism includes regulating discs, shafts, bearings and gears, the bearings are arranged on the standard ruler base, the shafts pass through the bearings, one end of each shaft is fixedly connected with the corresponding gear, and the other end of each shaft is fixedly connected with the corresponding regulating disc; the lifting platform can move back and forth under the drive of the transmission mechanism. The device has the advantages that the standard rulers can slide at will in the sliding grooves, when the standard rulers slide to the positions of points needing measurement, a fastening piece is used for fixing the standard rulers to the lifting platform, the regulating disc is rotated so as to move the lifting platform up and down until the two standard rulers are abutted to the thighbone and the shin bone, and the distance between any two corresponding points can be measured.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a distance measuring device. Background technique [0002] Total knee arthroplasty has become a common operation to solve severe knee joint lesions in clinical practice. It is mainly used for patients with severe knee joint pain, instability, deformity, severe limitation of activities of daily life, and conservative treatment is ineffective or the effect is not significant. In knee surgery, it is often necessary to ensure that the distance between the corresponding positions of the femur and the tibia is equal or the difference is within the allowable range of the operation. In clinical practice, the distance is often controlled by the surgeon's visual inspection, which results in the accuracy of the operation. to guarantee. [0003] This technical problem has not been solved, and the Chinese patent document CN106667589A discloses a knee joint distance measuring devi...
