Abstract

The invention provides an apparatus for locating a caput femoris centre, a patella centre and a second phalanx and locating equipment. The apparatus comprises a light receiving device, a light emitting device and a guiding device; the guiding device comprises a base, a pointer and a guiding block, the pointer is rotatably connected to the base, the guiding block and the base are arranged in a spaced mode, and the guiding block makes the pointer point to the guiding block; the light emitting device is rotatably connected with the base, and the central axis, rotating relative to the base, of thelight emitting device is parallel to the central axis, rotating relative to the base, of the pointer; an output end of the light emitting device faces the light receiving device, and the light receiving device and the guiding block are located at the two sides of the base respectively. The apparatus for locating the caput femoris centre, the patella centre and the second phalanx is an instrumentwhich can achieve accurate measurement of force lines of lower limbs and conduct locating after external fixation; the apparatus is easy to operate, practical, effective and capable of achieving fastlocating, so that the success rate of an operation is increased, and meanwhile, the pain of patients can be relieved, and damage to the patients is reduced.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a device and a positioning device for positioning the center of the femoral head, the midpoint of the patella and the second phalanx. Background technique [0002] As we all know, in the operation process of femur, tibia and knee joint, the operation failure is often caused by inaccurate and inaccurate positioning of the operation. For now, there is no method other than taking X-ray films to better measure the line of force of the lower limbs. At the same time, many hospitals do not have X-ray machines for irradiating the line of force of the lower limbs. Contents of the invention [0003] The object of the present invention is to provide a device for positioning the center of the femoral head, the midpoint of the patella and the second phalanx, so as to improve the problem of operation failure caused by inaccurate and inaccurate positioning. [0004] The purpose of the pres...
