The disclosed technology relates to closed-loop medical imaging for a medical environment. Various embodiments provide for a surgical camera, such as an endoscopic camera, comprising one or more image sensors. The image sensors may be configured to capture multispectral image data including one or more images of biological tissue (e.g., surfaces), and may be specifically configured to capture imagery within a surgical environment. For some embodiments, different biological tissues may be visible when illuminated by different wavelengths of a multispectral light source. The wavelength setting for the multispectral light source may be determined based upon a first wavelength setting associated with a first set of multispectral image data and a second wavelength setting associated with a second set of multispectral image data.

A wireless power transmission system for a robotic surgical system includes features for optical data transmission. A first component of the surgical system includes a control element, a power transmission element and an optical data transmission element; and a second component of the surgical system including a wireless power receiving element and an optical data receiving element, the second component is removably mountable to the first component. In some embodiments, a barrier such as a surgical drape and/or hermetic enclosure is positioned between the first and second components. In one example, of the components is a robotic manipulator arm and another is a powered instrument removably mountable to the manipulator arm.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

A medical observation device according to the present invention includes: an imaging unit that capture an image of a subject at a first angle of view; and an image generating unit that generates a display image signal by cutting, at a second angle of view smaller than the first angle of view, the image captured by the imaging unit at the first angle of view, and performing image processing thereon. This medical observation device enables the hand-eye coordination and definition to be maintained even if the field of view is changed.

A surgical visualization feedback system is disclosed. The surgical visualization feedback system comprises an emitter assembly configured to emit electromagnetic radiation toward an anatomical structure. The emitter assembly comprises a structured light emitter configured to emit a structured light pattern on a surface of the anatomical structure and a spectral light emitter configured to emit spectral light capable of penetrating the anatomical structure. The surgical visualization feedback system further comprises a waveform sensor assembly configured to detect reflected electromagnetic radiation corresponding to the emitted electromagnetic radiation and a control circuit in signal communication with the waveform sensor assembly. The control circuit is configured to receive an input corresponding to a selected surgical procedure, determine an identity of a targeted structure within the anatomical structure based on the selected surgical procedure and the reflected electromagnetic radiation, and confirm the determined identity of the targeted structure through a user input.

An endoscope includes in order from an object side, an objective optical system, an optical-path splitter, an image sensor, and an image processor. A λ/4 wavelength plate is disposed between the objective optical system and the splitter. The splitter includes first and second prisms, and has a beam splitting surface at which the first prism and the second prism are brought into close contact. The splitter splits light at the beam splitting surface, into a first optical path through which P-polarized light is transmitted and a second optical path through which S-polarized light is reflected. The first and second prisms are slid relative to one another along the beam splitting surface to adjust optical path lengths of the first and second optical paths, and are disposed at positions to cancel an amount of shift in focusing positions of extraordinary and ordinary light, and satisfy specific conditional expressions.

An optical module for endoscope includes a light emitting element, an optical fiber, a ferrule to which the light emitting element is bonded, a wiring board to which the ferrule is bonded, and a resin disposed between the ferrule and the wiring board, wherein the ferrule has a first principal surface made of a transparent material, a second principal surface, and a side surface, the second principal surface has an opening of an insertion hole, the second principal surface has an opening of a groove communicating with the insertion hole, the side surface has an opening of the groove, and a first distance between the opening of the groove on the side surface and the first principal surface is greater than a second distance between the bottom surface of the insertion hole and the first principal surface.

An optical module is configured being provided with: a first case fixed to an implementation surface of an implementation substrate to cover an LD and an LD driver; a first filler filled in the first case to seal the LD and the LD driver; a second case fixed to the implementation surface of the implementation substrate to cover the first case in a state of not adhering to the first case; a third case accommodating the implementation substrate and the second case inside; and a second filler filled in the third case to seal the implementation substrate and the second case.

Devices detect and assist in the avoidance of blood vessels during a surgical procedure—to avoid rupturing these blood vessels. Devices may be any penetration sensor device (such as a dilator sensor device, hollow needle sensor device, or trocar sensor device) that penetrates the skin and subcutaneous layers to reach a target location inside the body. The device includes a sensor probe which can make optical measurements to determine various parameters of the tissue at the tip of the sensor probe. These parameters may include an optical signal level returned from tissue contacting the tip of the sensor probe, an oxygen saturation level of the tissue, a total hemoglobin concentration, a blood flow, and a pulse. Based on these parameters, the presence or absence of a blood vessel at the tip of the device can be determined while the device travels towards the target location for surgery.

A surgical suturing tracking system is disclosed. The surgical suturing tracking system is configured to detect and guide a suturing needle during a surgical suturing procedure. The surgical suturing track system comprises a control circuit configured to predict a path of a needle suturing stroke after receiving an input from a clinician, detect an embedded tissue structure, and assess proximity of the predicted path and the detected embedded tissue structure.
