This invention discloses a parathyroid tissue transplantation device, belonging to the field of transplantation device technology, including a syringe, a cutting device, and a pusher. The cutting device has the same size as the inner wall of the syringe, and a through groove runs through the top surface of the cutting device. A material hopper is installed in the through groove, and the bottom surface of the material hopper is equipped with dense blades. A squeezing rod is placed in the material hopper, and a pusher plate is fixed at one end of the squeezing rod. The pusher plate has the same size as the inner wall of the material hopper. A drive component is installed inside the cutting device, which controls the rotation of the cutting blades. By setting up the syringe, cutting device, and pusher, the parathyroid tissue can be efficiently processed into a homogenate, realizing seamless linkage of tissue loading, cutting, and pushing. The entire process is completed in a closed structure, reducing tissue exposure, contamination, and residual loss. It realizes an integrated operation of immediate harvesting, processing, and transplantation during surgery, greatly improving the operation efficiency, standardization, and tissue survival rate of parathyroid tissue transplantation, and reducing the risk of postoperative hypoparathyroidism.

The application provides a camera equipment for an electric knife, and belongs to the technical field of auxiliary camera equipment for electric knives, and comprises an electric knife provided with a binocular depth camera and a processor. The processor acquires a synchronous video stream through the binocular depth camera, and recognizes a recurrent laryngeal nerve and parathyroid region and boundary points thereof by using a pre-trained neural network, and then constructs three-dimensional coordinates of the boundary points with the end of the electric knife as the origin. The system continuously tracks the movement of the boundary points, and predicts the future positions by analyzing the historical trajectories. If the boundary point closest to the electric knife in the predicted points exceeds a safety threshold, the system will issue a real-time warning. The equipment can dynamically identify and predict the movement of key tissues, and assist the doctor to actively avoid intraoperative risks.

One embodiment provides a tightly targeted minimally invasive therapy (TTMIT) parathyroid tissue ablating instrument. A substance that cytotoxically ablates parathyroidal tissue during application in the parathyroidal tissue of therapeutically sufficient units of an electromagnetic energy having a frequency only ranging from ultraviolet to visible to near infrared. A substance delivery device is configured to introduce the substance into the parathyroidal tissue. An electromagnetic energy treatment device is configured to apply the therapeutically sufficient units of the electromagnetic energy within a thermal range that is non-cytotoxic to the parathyroidal tissue to the substance after the substance has been introduced by the substance delivery device. A sensor is configured to monitor activation of the substance as the therapeutically sufficient units of the electromagnetic energy are applied. The electromagnetic energy treatment device is further configured to modulate applying the therapeutically sufficient units of the electromagnetic energy once the substance has been activated.
