A hand-held vision sensor apparatus comprises a plurality of light sources, control activation elements and an image sensing array, encased within a housing such that the control activation elements are disposed at a user-accessible location on the housing. The housing further includes a pair of exit apertures for emitting illumination directed toward a medical specimen and an entrance aperture for capturing reflected light from the medical specimen. The light sources are disposed in alignment with the pair of exit apertures, and the image sensing array is aligned with the entrance aperture. The control activation elements are utilized to energize the light sources and control the functioning of the image sensing array. A computer port may be included and used to communicate command controls to the light sources, image sensing array and control activation elements in a manner that allows for a remotely-located technician to communicate with the hand-held vision sensor.

Disclosed are medical examination or diagnostic instruments and methods of operating such instruments. The method can include coupling an instrument head to a handle to form a medical examination or diagnostic instrument; detecting by the instrument head, a characteristic of the handle; and based at least in part on detecting the characteristic of the handle, determining, by the instrument head, a handle type associated with the handle, or detecting by the handle, a characteristic of the instrument head, and based at least in part on detecting the characteristic of the instrument head, an instrument head type associated with the instrument head. In some implementations, the emission of light can be controlled to be approximately linear in relation to a user input signal, as perceived by a user.

The present disclosure relates to visualizing an operative field in the context of a dental operating theater, and more specifically, to a portable, modular, multifunctional intraoral imaging system to assist a practitioner in performing a medical or dental procedure in a confined space (e.g., intraoral cavity or mouth of a patient). The system may include an intraoral camera apparatus having a camera unit equipped with a wireless transmitter, and a viewscreen mounted to an articulated stand or dental delivery unit, wherein the camera wirelessly may transmit an image to a viewscreen located directly in front of a dental practitioner. The practitioner may look directly ahead at a high-definition screen to view the operative field. A dental practitioner may use the apparatus to perform micro-surgical procedures in a confined operative area with less-than-ideal visibility and access, without the present, though generally accepted, physical difficulties and limitations.

A system and a method for a medical diagnostic device are described herein. The medical diagnostic device can include an outer sleeve having a hollow interior and open distal and proximal ends, the outer sleeve being defined by a substantially tubular configuration including a proximal section having a substantially conical shape. A core is configured to be inserted axially within the outer sleeve. The core includes an axial inner cavity. The core is further defined by a proximal section having a conical shape substantially conforming to the proximal section of the outer sleeve. The core retains a diagnostic assembly, that can include at least one of a sample collecting assembly and an imaging assembly, that can be integrally or interchangeably attached and wherein the device can be utilized for self-patient or single patient use.

A speculum comprising a lower member including a handle having a proximal end and a distal end, and a lower blade extending from the proximal end of the handle, an upper blade configured to be movable with respect to the lower member, and an illumination assembly including at least one light source, at least one power source housed in the handle and an ejection mechanism for removal of the at least one power source from the handle, wherein the at least one power source is housed in the handle at a position closer to the proximal end of the handle than to the distal end, and wherein the ejection mechanism is configured to remove the at least one power source via an opening formed in the distal end of the handle.

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.

Medical endoscope imaging systems and methods of using the same are disclosed. The imaging systems can have an endoscope having an image sensor, a display housing having an image display, a communication link configured to couple the image sensor to the image display, and a camera housing having a camera-sensor. The display housing can be configured to be detachably coupled to the camera housing. The camera-sensor can be configured to receive signals from the image display.

An enhanced optical design for imaging of live human tissue as a supplemental attachment to wireless mobile devices such as smartphones. The improved imaging system includes a series of optical ball lenses coupled to a medical-grade light source to allow universal compatibility to mobile device (e.g., smartphone) cameras. The releasable optical attachment comprises optical enhancement elements allowing universal compatibility without the need of an application or special program to re-orient the image therein permitting less loss of picture acuity and blanket usability to HIPAA-verified smartphone applications used in hospitals and patient's electronic health records. The addition of an external light source and light-redirecting elements negates the need for a smartphone light source or smartphone re-programming to illuminate target.

A wireless medical imaging system comprising a head unit is provided. The head unit comprises a head unit case, an integrated light source, an image sensor, a wireless transceiver, a central processing unit, and a user-input component. The head unit case has an external surface defining an external cavity, an internal surface defining an internal cavity, a first aperture, and a second aperture. The integrated light source, the image sensor, the wireless transceiver, and the central processing unit are disposed within the internal cavity. The integrated light source extends from within the internal cavity into the first aperture and is configured to transmit light from the head unit through the first aperture. The image sensor is configured to detect an image trans-nutted into the head unit through the second aperture. The external cavity is configured to receive an external battery. The user-input component is disposed on the external surface.
