Abstract
The utility model provides a multifunctional osteotomy angle measurer. The upper part of a locating rod is sheathed in an arc angle measuring disc; the upper part and the bottom part of the measuring disc are respectively equipped with an adjusting nut which is connected with the locating rod in screw thread fit; a sliding sheath is installed between the measuring disc and the adjusting nut on the bottom part; the wall of the sliding sheath is equipped with a pointer which is capable of rotating; the bottom part of the locating rod is equipped with a tapping screw thread. As using, the locating rod is fixed on the bone which is to be rotated through the tapping screw thread, and the pointer is arranged at the null point, then the pointer can indicate the rotating angle under the action of gravity by rotating the angle of the bone which is to be operated, thus the angle measuring process of the rotating bone is completed. By using the mechanical measuring device, the rotating angle of the bone to be cut can be measured exactly, and the empirical error caused by visual inspection can be prevented from affecting the operation effect; the success rate of osteotomy operation can be improved with convenient operation and exact measure and location.
Description
Technical field
The utility model discloses a kind of multi-functional osteotomy angle measuring instrument, is used for orthopaedics bone-culting operation apparatus, belongs to the orthopedic medical device technical field.
Background technology
At present, in orthopaedics bone-culting operation process, also not having special-purpose osteotomy angle surveying instrument, is the experience range estimation osteotomy angle by the doctor, and randomness is bigger, often because the deviation of osteotomy angle influences surgical effect, brings misery to the patient.
Summary of the invention
The utility model provides a kind of multi-functional osteotomy angle measuring instrument, accurately measures the operation angle of osteotomy by mechanical hook-up, has avoided experience to judge the randomness error of range estimation osteotomy angle.
Technical solution of the present utility model is as follows: the measurement of angle dish that is set with arc on the top of backstay, the top of measuring disk is respectively equipped with the adjustment nut with the bottom and is connected with the backstay threaded engagement, sliding bush apparatus is adjusted between the nut in measuring disk and bottom, and the sliding sleeve wall is provided with rotating pointer; The bottom of backstay is provided with tapping thread, is used to be screwed into the bone of pre-rotation.
The utility model is fixed on backstay on the operation bone of pre-rotation by the tapping rib-loop in use, and pointer is adjusted into zero point, and by rotating the angle of pre-osteotomy, pointer is indicated rotational angle under action of gravity, finishes the measurement of angle of rotating bone.
Good effect of the present utility model is: utilize mechanical measuring device can measure pre-osteotomy head-turned angle accurately, avoid the error effect surgical effect of the experience of estimating, easy for operation, measurement and positioning is accurate, has improved the success ratio of bone-culting operation.
