Abstract

The invention is suitable for the medical instrument technology field, and discloses a hand-operated minimally invasive spinal column operation guiding device. The guiding device comprises a vertical main body support bar, a vertebra fixing mechanism two ends of which extend out of the main body support bar and one end is fixed on the vertebra of a patient, an adjusting mechanism that is arranged at one end of the main body support bar and is used for hand-operated adjusting, and a guiding mechanism arranged at the end of the adjusting mechanism for position and posture adjustment with the help of the adjusting mechanism. The vertebra fixing mechanism can be fixed directly on a patient's spinal column, therefore, influence of spinal column follower generated by physiological respiratory movement to positioning is reduced and operation precision is improved; by hand-operated adjusting, influence of power off during the operation and other emergent events to the operation is avoided, thereby guaranteeing operation security; by arranging the adjusting mechanism, pedicle nail channel position and attitude adjusting at different vertebra segments can be realized, and operation guiding is provided by arranging the guiding mechanism.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, in particular to a manual minimally invasive spinal surgery guide. Background technique [0002] With the rapid development of computer and microelectronics technology and medical science, various computer-aided medical technologies and equipment emerge in an endless stream. In spinal surgery, intraoperative navigation technology under the guidance of three-dimensional navigation has been widely used. The doctor determines the position and posture of the operation according to the images given by the computer-aided equipment. However, the operation process is still performed by doctors with bare hands. There are two main disadvantages: first, the positioning in three-dimensional space is relatively easy, but the posture adjustment is more difficult; second, the accuracy and fatigue of the doctor's manual operation may easily cause inaccurate positioning. [0003] At present, there ...
