Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a mobile laser positioning system. Background Art

[0002] The mobile laser positioning system plays a very important role in the simulation positioning, treatment positioning and repositioning before radiotherapy to ensure the accuracy of radiotherapy, reduce the dose of normal tissues and improve the treatment effect of patients. The mobile laser positioning system marks the position of the tumor center by projecting laser on the human body, and the laser marker can be offset according to clinical needs to achieve accurate positioning and positioning in the radiotherapy process.

[0003] At present, most mobile laser positioning systems are three-axis and can be used to position the patient's sagittal and coronal planes.

Due to the limitation of the movement accuracy of the CT bed, the patient's position needs to be frequently calibrated and debugged through the CT bed. For critically ill patients or patients with inconvenient movement, frequent position adjustments will cause additional pain to the patients and increase their psychological pressure.

[0042] Some embodiments of the present application disclose a mobile laser positioning system, including a movable coronal laser light device 1, a movable sagittal laser light device 2 and a movable transverse laser light device 3, wherein the movable coronal laser light device 1 is used to indicate the patient's coronal plane, and the moving direction of the laser light of the movable coronal laser light device 1 is along the front-to-back direction of the patient, the movable sagittal laser light device 2 is used to indicate the patient's sagittal plane, and the moving direction of the laser light of the movable sagittal laser light device 2 is along the left-right direction of the patient, the movable transverse laser light device 3 is used to indicate the patient's transverse plane, and the moving direction of the laser light of the movable transverse laser light device 3 is along the body length direction of the patient.

[0043] like Figure 1 As shown, the cross-section is a section that divides the human body into upper and lower parts in the direction perpendicular to the head and feet of the human body, the coronal plane is a section that divides the human body into front and back (front chest and back) parts, and the sagittal plane is a section that divides the human body into left and right (left and right parts). The section that coincides with the long axis is the median sagittal plane.

[0044] The mobile laser positioning system disclosed in the present invention is used to indicate the coronal plane, sagittal plane and transverse section of the patient by using a combination of a movable coronal laser light device 1, a movable sagittal laser light device 2 and a movable transverse laser light device 3. The movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 can be moved separately, that is, the laser lights of the movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 move relative to the patient to indicate the coronal plane, sagittal plane and transverse section of the patient, which improves the patient's experience of use compared to the method of locating the coronal plane, sagittal plane and transverse section by adjusting the patient's position.

[0045] The movable transverse laser light device 3 of the mobile laser positioning system disclosed in the present application can realize the movement of the laser light through its own structure to indicate the cross section and realize the positioning of the mobile cross section. Compared with the method in the prior art of using a CT machine to drive the patient to move so that a fixed laser light indicates the cross section, there is no need to rely on a CT machine, so that the arrangement of the movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 of the mobile laser positioning system is not restricted by the CT machine, thereby improving the flexibility of the arrangement of the movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3.

[0046] The arrangement of the movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 is not restricted by the CT machine, so that the selection of the installation position of the movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 is also more flexible.

[0050] The movable coronal laser light device 1, the movable sagittal laser light device 2 and the movable transverse laser light device 3 communicate and move synchronously via Bluetooth.

[0051] The mobile laser positioning system is used to indicate the sagittal, transverse and coronal planes of the patient during the positioning and repositioning process of radiotherapy. The laser mark projected onto the human body marks the center of the tumor. The laser mark can be offset according to clinical conditions to achieve precise positioning and positioning functions in the radiotherapy process.

[0052] During radiotherapy positioning, the patient's positioning center can be determined based on the intersection of the coronal laser lines of the left coronal laser light mechanism 11 and the right coronal laser light mechanism 12, the sagittal laser line of the sagittal laser light mechanism, and the transverse laser lines of the left transverse laser light mechanism 31 and the right transverse laser light mechanism 32; during radiotherapy repositioning, the laser lights of the movable coronal laser light device 1, the movable sagittal laser light device 2, and the movable transverse laser light device 3 can be moved according to the offset between the tumor center and the positioning center in the medical image, and then the position of the tumor center is determined based on the intersection of the moved coronal laser line, sagittal laser line, and transverse laser line, and then a CT scan is performed to verify the accuracy of the repositioning.

[0067] The elastic member is located between the fixing plate 312 and the adjusting plate 313, and is used to apply thrust to the adjusting plate 313 so that the adjusting plate 313 always abuts against the adjusting nut to prevent the position of the adjusting plate 313 from changing during use, thereby improving the working stability of the laser lamp.

[0068] When the angle of the laser lamp needs to be adjusted, the adjusting nut at the corresponding position is adjusted according to the angle requirement, and the adjusting plate 313 slides along the axis of the adjusting rod 314 under the thrust of the elastic member so that the adjusting plate 313 abuts against the adjusting nut.
