An electronic device may include body composition analysis circuitry that estimates body composition based on captured images of a face, neck, and/or body (e.g., depth map images captured by a depth sensor, visible light and infrared images captured by image sensors, and/or other suitable images). The body composition analysis circuitry may analyze the image data and may extract portions of the image data that strongly correlate with body composition, such as portions of the cheeks, neck, waist, etc. The body composition analysis circuitry may encode the image data into a latent space. The latent space may be based on a deep learning model that accounts for facial expression and neck pose in face/neck images and that accounts for breathing and body pose in body images. The body composition analysis circuitry may output an estimated body composition based on the image data and based on user demographic information.

Systems and methods for image-guided medical procedures use fluoroscopic 3D reconstructions to plan and navigate a percutaneously-inserted device such as a biopsy tool from an entry point to a target.

A measuring instrument configured to measure a bone and a plate to determine the size of an attachment clamp, including: a medial clamp configured to engage a medial portion of the bone; a medial gauge connected to the medial clamp, the medial gauge including: a key along a portion of the medial gauge adjacent the medial clamp; a gauge indicator configured to indicate the size of attachment clamp; and a threaded portion; a lateral clamp configured to engage a plate on the bone, where the lateral clamp has a hollow portion with a channel, wherein the gauge indicator is positioned in the hollow portion and wherein the channel is configured to engage the key of the gauge indicator to prevent the lateral clamp from rotating about the gauge indicator; and a tightening knob threaded onto the thread portion of the of the medial gauge, wherein one end of the tightening knob indicates on the gauge indicator the size of the attachment clamp.

Systems and methods are provided for determining acceptable ranges of pressures for use by a robotic arm on a surgical instrument, robotic systems and methods that are limited to using the acceptable ranges of pressures, and the medical devices for use in the robotic surgery. Learning software is included in the methods and systems for correlating manually-performed procedures with pressure sensors as a tactile gauge for qualifying the acceptable ranges of pressures for use by a robotic system. Robotic systems and methods are provided for (i) locating tissue borders of a surgical site, (ii) identifying a preferred pressure, and (iii) transmitting the data to the computer to avoid violating the integrity of tissue surrounding the surgical site.

A surgical device for intraoperative angle measurements during surgery. The surgical device includes a shaft having a bone probe configured to remain in contact with cortical bone of the patient while a user orients the shaft to a desired orientation. The device includes a housing having an electronic circuit configured to measure an orientation angle. The electronic circuit may include: an input device configured to receive user input data; a measurement circuit configured to measure a change in orientation of the shaft in relation to a reference axis; a control circuit coupled to the input device and measurement circuit and configured to determine the orientation angle of the shaft relative to the reference axis; and an output device configured to communicate the orientation angle to the user. The device includes a power supply configured to provide power to the electronic circuit.

A tool for a bone implant includes a rod and an adaptor. The rod includes a coupling portion having a through-hole. The rod further includes a measuring arm connected to the coupling portion and a force applying arm connected to the coupling portion. The measuring arm includes a first extension section having a first indicator portion, and the force applying arm includes a second extension section having a second indicator portion. The force applying arm is elastically deformable away from the measuring arm to displace the second extension section relative to the first extension section. The adaptor is coupled in the through-hole and includes an outer ring and an inner ring. The outer ring is rotatable relative to the inner ring in a single direction.

A biopsy gun having a cannula and a stylet guided in the cannula comprises the following a housing, a cannula carriage for moving the cannula, a stylet carriage for moving the stylet, a tensioning grip for tensioning the cannula carriage and the stylet carriage from an initial position into a tensioning position, and an engaging member that is provided on the tensioning grip and has recesses adapted to engage with corresponding projections of the cannula carriage and the stylet carriage. The engaging member is rotatably attached to the tensioning grip and is biased by a spring against a contact surface of the housing.

Techniques are described for testing whether an end effector, or component thereof, is correctly or incorrectly installed to a manipulation system. In an example, a manipulation system can include a manipulator arm configured to receive an end effector having a first moveable jaw, a transducer configured to provide first effort information of the end effector as the end effector moves, and a processor configured to provide a command signal to effect a first test move of the first moveable jaw, and to provide an installation status of the of the end effector using the first effort information of the first test move.

A method of assembling a measurement module used for bore depth determinations in tissue. The measurement module has a housing. A gear having a plurality of gear teeth is disposed within and rotatably coupled to the housing. The measurement module further includes a bushing and a depth extension member having a plurality of rack teeth extending along a depth extension axis. The depth extension member is disposed within a bore of the bushing and the housing. The rack teeth of the depth extension member are arranged to be engaged by the gear teeth of the gear. The depth extension member is urged toward the gear so that the rack teeth are in meshed engagement with the gear teeth. The bushing is fixed to the housing while the depth extension member is urged toward the gear.

Systems and methods are disclosed in which changes in the position and/or orientation of an anatomical structure or of a surgical tool can be measured quantitatively during surgery. In some embodiments, the systems and methods disclosed herein can make use of inertial motion sensors to determine a position or orientation of an instrument or anatomy at different times and to calculate changes between different positions or orientations. In other embodiments, such sensors can be utilized in conjunction with imaging devices to correlate sensor position with anatomical landmarks, thereby permitting determination of absolute angular orientation of a landmark. Such systems and methods can facilitate real-time tracking of progress during a variety of procedures, including, e.g., spinal deformity correction, etc.
