The connector assembly comprises a plug at the proximal end of the shaft with an outer circumferential wall and a first plurality of electrical terminals, and a receptacle in the handle with a cavity for the plug. An image sensor is at the distal end of the shaft, and a plurality of electrical conductors electrically connected to the image sensor, are electrically connected to the first plurality of electrical terminals. An inner circumferential wall of the receptacle includes a second plurality of electrical terminals, and the outer circumferential wall of the plug has a plurality of apertures therein through which the first plurality of electrical terminals establishes an electrical connection with the second plurality of electrical terminals when the plug is inserted in the receptacle.

Endoscopic light refraction imaging techniques are described for configuring a viewing trocar and/or angled endoscope with a light refracting element, such as glass and/or plastic prism for instance. The light refracting element can be utilized in and/or with the viewing trocar to refract (i.e., bend) light passing into the trocar through the trocar's window. As a result, the angled endoscope's field of view can be substantially aligned with the field of view of the trocar's window, thus allowing the angled endoscope and viewing trocar to be used together to create ports in a patient, including initial ports of endoscopic surgical procedures.

Provided is an endoscope that can connect proximal ends of the first signal lines and a signal relay part together without securing an extra length for the first signal lines. An airtight casing is disposed inside an outer tube of an insertion part, an imaging device and first signal lines are accommodated inside the airtight casing, a distal end of the airtight casing is airtightly sealed by a cover glass, and a proximal end of the airtight casing is airtightly sealed by a partition wall part. The airtight casing is constituted of a first tubular body and a second tubular body, and the second tubular body is disposed in a nested shape with respect to the first tubular body. During the connection between the proximal ends of the first signal lines and the terminal part, the second tubular body is advanced toward the first tubular body.

An exemplary medical system includes a first electrical circuit on a printed circuit board (PCB) and configured to generate data, a second electrical circuit on the PCB and electrically isolated from the first electrical circuit, and a radio frequency (RF) communication interface assembly on the PCB.
