Abstract

The invention discloses a minimally invasive sighting device, which comprises a crossbeam, a first clamping device, a second clamping device and a third clamping device, wherein the first clamping device comprises a first base and two first clamping arms; a first adjusting bolt and a first locking bolt are arranged on each first clamping arm; the second clamping device comprises a second base and two second clamping arms; a second adjusting bolt and a second locking bolt are arranged on each second clamping arm; the third clamping device comprises a third base and two third clamping arms; a third adjusting bolt and a third locking bolt are arranged on each third clamping arm; a sleeve is clamped between the two third clamping arms; a first through hole is formed on the second base; a second through hole is formed on the third base; and the crossbeam penetrates through the first through hole and the second through hole. The minimally invasive sighting device is simple in structure, convenient to operate and low in cost.

Description

technical field [0001] The invention relates to a medical device, in particular to a minimally invasive collimator. Background technique [0002] Modern people often suffer from spinal injuries or degenerative lesions due to years of poor sitting or sleeping postures, wrong exercise methods, or other accidents. In order to improve the impact of spinal deformation on patients' work and rest, It is necessary to adjust and fix the traumatized or diseased vertebrae through surgery, and then cooperate with subsequent correction and rehabilitation work, so that the entire or partial vertebral structure can return to normal. Under the premise of considering ergonomics and structural strength, an appropriate spinal fixator can be designed and implanted into the injured or diseased vertebral body, and the appropriate span and angle can be adjusted according to the condition of the patient's spine, so that The entire fixer is integrated with the vertebral body to achieve a complete f...
