The invention discloses a robot calibration method for spine endoscopic surgery, which comprises the following steps: S1, optical marking points are pasted on the skin or bony structure of a patient, the skin marking is used for fixing a reflective ball by using a medical adhesive tape, the bony marking is percutaneously implanted into a spinous process or crista iliaca through a titanium alloy bone nail, and at least six marking points are needed. According to the method, minimally invasive property and stability are both considered through a double marking strategy, six points cover three vertebral bodies to ensure the integrity of an anatomical range, registration errors caused by breathing / body position changes are reduced, meanwhile, non-rigid registration is combined with a B spline grid (10 mm) to consider calculation efficiency and spine physiological curvature adaptability, high-precision surface reconstruction is achieved through a Marching Cubes algorithm, and the method has the advantages of being high in precision and high in precision. An error suppression mechanism is formed by + / -0.25 mm precision and redundancy measurement (five times of sampling) of the optical tracking system, registration robustness is improved through SVD and ICP double-algorithm complementation, multi-constraint path planning is achieved through an A * algorithm and Monte Carlo simulation, and a 4 mm safety corridor provides a buffer space for instrument errors.

A skin marking device is provided. The skin marking device has an outer frame that can be fitted over an ultrasound probe. The ultrasound probe can be used to identify a location for a needle or other medical device. Once the location is identified, the probe may be removed while keeping the frame in place. A skin-marking tool may then be fitted with / into the frame to mark the skin, thereby identifying the precise location for action.

This application provides a skin marking device, belonging to the field of medical auxiliary tool technology. The marking device includes a spring ruler and a support. The spring ruler is mounted on the support, which is mounted on a positioning integrated plate for marking lines on the side of the chest. An elongated hole is provided on the spring ruler, and a skin marking pen is placed inside the elongated hole and moves along the hole to draw lines. Auxiliary lines are provided on the spring ruler, located at both ends of the elongated hole, and are used to check the laser projection lines. This improves both the accuracy and efficiency of the marking. Furthermore, all marked line segments are upright and of uniform thickness, ultimately improving the precision of lesion treatment for patients.

This invention discloses a skin marking system for ultrasound imaging, a dedicated coupling agent, and its application method, relating to the field of medical ultrasound imaging auxiliary equipment and medical coupling agents. It includes a dedicated photocurable coupling agent and a specially designed ultrasound probe. The dedicated photocurable coupling agent comprises a water-soluble medical ultrasound coupling agent matrix, a photocurable hydrogel precursor, a photoinitiator, and a color developer. The specially designed ultrasound probe includes a probe housing with a built-in ultrasound transducer and a probe end face for contacting the skin. At least one ultraviolet light source is integrated in the central region of the probe end face. The relative position of the ultraviolet light source and the ultrasound transducer is spatially calibrated to establish a preset coordinate mapping relationship between the irradiation area of ​​the ultraviolet light source and the ultrasound scanning area of ​​the ultrasound transducer. This invention achieves simultaneous and precise skin marking and diagnostic guidance for ultrasound imaging through an ultrasound probe integrating an ultraviolet light source and a photocurable dedicated coupling agent.
