An apparatus for obtaining an image of a retina has an optical relay that defines an optical path and is configured to relay an image of the iris along the optical path to a pupil; a shutter disposed at the pupil and configured to define at least a first shutter aperture for control of light transmission through the pupil position; a tube lens disposed to direct light from the shutter aperture to an image sensor; and a prismatic input port disposed between the shutter and the tube lens and configured to combine, onto the optical path, light from the relay with light conveyed along a second light path that is orthogonal to the optical path.

A surgical device includes one or more cameras integrated therein. The view of each of the one or more cameras can be integrated together and provided to a surgeon display and/or an assistant display. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the images generated by the one or more cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as at least partially transparent. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

Portable surgical systems, methods, and kits are described. The surgical systems may include a camera configured to capture images, viewing equipment configured to receive and display the captured images, a processor, and a stand. The camera, the viewing equipment, the processor, and the stand are configured to be housed in a case. Surgery may be performed using the surgical system by retrieving surgical components from the case, assembling the retrieved surgical components into a surgical system, positioning a patient within the surgical system for surgery, configuring the surgical system, performing the surgery with the surgical system, reconfiguring the surgical system during the surgery, disassembling the surgical system after the surgery, and placing the components in the case.

A robotic surgical system for treating a patient includes a surgical robot with a moveable robot member, an actuator for moving the robot member to 6D poses in a surgical field and for driving the robot member to act in the surgical field, a robot sensor for providing robot sensor data, and a control device for controlling the actuator according to a control program and under feedback of the robot sensor data, a processing unit configured to provide the control program to the control device, and to include and utilize a virtual anatomical model, a virtual surgical robot simulating movement and driving of the robot member, a surgical simulator, a sensor simulator, and a machine learning unit to create the control program, the machine learning unit reading the sensor simulator, the virtual surgical robot, and the virtual surgical field and feeding the virtual surgical robot.

This system is composed by mechanical telemanipulators, with master-slave configurations, working together with suitable solutions for image acquisition and display, which are able to transmit, with optional magnification, images from the surgical area to the surgeon. Therefore, the surgeon's capacities and comfort are increased by enhancing the surgeon's motor and visual skills as well as the ergonomics while doing different surgical tasks through access incisions on the patient body. Aside from offering improved performance during procedures involving microsurgical techniques, this system also brings safety, intuitiveness, and cost-effectiveness advantages over current alternatives. Due to the compatibility with current visualization systems for microsurgery, together with the light weight and the compact configuration of the mechanical telemanipulator, this surgical system can be very easily brought to and removed from the surgical area, which enables its intermittent use on several surgical procedures requiring microsurgical techniques. Therefore, it does not require drastic changes in the workflow and setup of current operating rooms and can be more easily adopted by several surgical teams.

A camera device includes a camera head that captures an observation image of a target site which is obtained by a surgical microscope, and a camera control unit that processes a signal of the observation video captured by the camera head. The camera head captures right and left observation images having a parallax from the surgical microscope to obtain a high-resolution observation video including right and left parallax videos for one screen, and the camera control unit cuts out the right parallax video and the left parallax video from the observation video including the right and left parallax videos to generate a high-resolution 3D video which is displayed on a monitor in 3D and with which stereoscopic observation can be performed.

An intraoperative near-infrared-I and near-infrared-II multi-spectral fluorescent navigation system and method of using same includes a light source module for emitting white light and excitation light for illuminating tissue to be tested to generate an emission light. An optical information collection module includes a white light camera for collecting the white light image, and near infrared-I and near infrared-II fluorescence cameras for collecting the near infrared-I and near infrared-II fluorescence images. A central control module is coupled to the light source and the optical information collection modules. An image processing unit pre-processes the white light image, and the near infrared-I and near infrared-II fluorescence images, for de-noising and enhancement. The image processing unit performs a pseudo-color mapping on the images to obtain pseudo-color superimposed images of the near infrared-I and near infrared-II for a surgical region, and completes imaging of the intraoperative near-infrared-I and near-infrared-II multi-spectral fluorescent navigation system.

An article of personal protective equipment (PPE) for covering a wearer's face when wearing loupes and/or a light mounted to an eyeglass frame, the apparatus including a set of adapters, each adapter mounted or configured for mounting to an eyeglass frame, wherein each adapter has an outward extending protrusion; and a transparent face shield with opposing sidewalls joined by a convex front with upper and lower portions angled inward to cover the wearer's face when wearing the loupes and/or light, each sidewall configured to engage one of the protrusions to align an apex of the convex with the loupes and/or light.

A binocular device for visualizing optical radiation comprises a support structure, a left camera, and a right camera coupled to the support structure. The left camera comprising left optics and a left image sensor, the right camera comprising right optics and a right image sensor, the left image sensor and the right image sensor being configured to create left and right video signals from detected optical radiation received from the corresponding left and right input optics about a same field of view along respective left and right input optical axes. A specular reflection is detected.

An objective lens system for an optical biopsy device has a lens that comprises a first part configured for viewing at a first magnification, and a second part configured for viewing at a second magnification. The second magnification is substantially different from the first magnification. The first magnification enables viewing a larger area of a target and the second magnification enables viewing the target at a cellular level with high sensitivity and specificity. Combining viewing at two different magnifications in a single objective lens results in a compact optical biopsy device.
