Abstract: A real-time, intra-uterine operating field image is displayed to an operator. A processor identifies anatomical features and marks anatomical boundaries on the image with the aid of a trained classifier model. Labels for the identified anatomical features and the anatomical boundaries are displayed on the image. The trained classifier model is trained based on a set of prior surgical field images that have anatomical features and anatomical boundaries therein identified and marked, respectively, by previous operators. The trained classifier model is typically a convolutional deep neural network. The operator is allowed to modify the anatomical feature labels and anatomical boundaries, as well as update the set of training images with the modified image. The labeling of the anatomical features and establishment of the anatomical features facilitate performing treatments in the uterus, such as the ablation of uterine fibroids.

Abstract: A control handle of a treatment probe is manipulated to advance and/or deploy one or more treatment structures into tissue. The treatment probe is coupled to a display to show an image field including target tissue for treatment. Virtual treatment and safety boundaries are overlaid over the image field. The boundaries include virtual stop positions for the needle and tines. A joystick or directional pad on the probe handle, operable independently from the user interface to advance and/or deploy the one or more treatment structures, can be manipulated to adjust the size and/or position of these boundaries. Sensors within the probe detect the real-time position of the one or more treatment structures, and the sensed positions are displayed in real-time. The user can observe the display to deploy the one or more treatment structures to the displayed virtual stop positions.

Abstract: Various systems, devices, and methods for tissue penetration are disclosed. The system includes an ablation element that penetrates the tissue and a radiofrequency generator that delivers energy to the ablation element. The radiofrequency generator may have two modes: a cutting or insertion mode and an ablation or coagulation mode. The cutting or insertion mode is used to cut or penetrate the tissue by providing a voltage or power modulation that acts to cut or soften tissue contacted by the ablation element. The ablation or coagulation mode is used to ablate or coagulate the tissue.

Abstract: A group photo interaction method includes: displaying a target group photo template including a first bearing position that bears a first virtual image corresponding to a current object and at least one second bearing position configured for bearing a virtual image corresponding to an invited interaction object; displaying impression information edited for the interaction object, the impression information being configured for indicating an impression of the current object for the interaction object; transmitting, in response to a group photo invitation operation for the interaction object, a group photo invitation bearing the impression information to a terminal corresponding to the interaction object; and displaying a second virtual image at a second bearing position in the target group photo template when the interaction object responds to the group photo invitation based on the impression information, and obtaining a target group photo including the first virtual image and the second virtual image.

Abstract: Systems and methods for treating tissue are disclosed. The target tissue is ablated. A real-time image of the target tissue is generated during the ablation. The real-time blood perfusion level of the target tissue is determined from the real-time image and compared to an initial blood perfusion level of the target tissue. The comparison provides a metric for the progress of the ablation, and ablation is halted when the real-time blood perfusion drops below a threshold level relative to the initial blood perfusion level.

Abstract: A spinning top toy includes a spinning top accelerator and a spinning top body movably connected with the spinning top accelerator. The spinning top accelerator includes a housing and a driving device, a clamping assembly and an injection pushing assembly disposed in the housing. The driving device includes a case and an acceleration gear set which is rotatably provided in the case. A gravity block is slidably provided on the case, and the gravity block is drivingly connected to the acceleration gear set. The clamping assembly is drivingly connected to the acceleration gear set, and is used to movable clamp the spinning top body. The injection pushing assembly is used to push the spinning top body. When the gravity block slides back and forth on the case by swinging, the gravity block drives the acceleration gear set to rotate, thereby driving the clamping assembly to rotate.
