Abstract

The invention belongs to the technical field of laser guidance equipment, and discloses a coplanar mechanism used for laser guidance and a control system thereof. The mechanism includes laser track equipment, and a first sliding arm and a second sliding arm arranged at the bottom of the laser track equipment, and is characterized in that the bottom of the first sliding arm is provided with a firstslide rail mechanism which is connected to the second sliding arm and drives the second sliding arm to slide relative to the first sliding arm; and the bottom of the second sliding arm is provided with a second slide rail mechanism which is used for connecting to a laser emission head and drives the laser emission head to slide relative to the second sliding arm. Plane displacement can be performed by controlling the first slide rail mechanism through a first servo motor, so that accurate positioning can be performed on angles, position adjustment can also be performed on the angles, and therefore, the positions and angles of the laser emitted by the laser emission head can be more complete; and the mechanism is smaller in size, so that moving error can be avoided, movable ranges can be more accurate, and therefore, the mechanism is more suitable for accurate adjustment of small ranges.

Description

technical field [0001] The invention belongs to the technical field of laser guiding equipment, in particular to the field of laser guiding coplanar mechanisms, in particular to a laser guiding coplanar mechanism and a control system thereof. Background technique [0002] Radioactive seed implantation treatment technology is based on the results of ultrasound, CT, MRI and other imaging examinations. First, the radioactive seed treatment planning system (Treatment Planning System, TPS) is used to accurately design the position, quantity, and implantation route of radioactive seed implantation, and formulate a treatment plan. Then, guided by CT, B-ultrasound, endoscope or percutaneous puncture under the direct vision of surgery, the radioactive particles are implanted into solid malignant tumors according to the plan through the particle implantation gun; finally, the continuous low-energy X-rays emitted by the radioactive particles Rays or γ-rays can destroy tumor tissue to t...
