Description

Omni-directional adjustment mount for medical mobile cameras

technical field

The utility model relates to the field of photographing equipment, in particular to an omnidirectional adjustment frame of a video camera that can meet the requirements of surgical video recording.

Background technique

Traditional surgical camera brackets mainly include the following two types: one is the ceiling-mounted surgical video equipment, the camera is fixed on the top of the operating room or the shadowless lamp base through the bracket, and a sterile handle is installed on the base of the camera during the operation, and the height of the camera can be adjusted by the surgeon or an assistant. Camera angle; the second is head-mounted surgical video equipment, the camera is fixed on the head of the surgeon through a bracket, and the camera angle is adjusted by moving the head.

The ceiling-mounted surgical video equipment is located above the sterile surgical field, and the camera angle must be adjusted by the surgeon. During the intense operation, the surgeon cannot adjust the camera angle from time to time as the surgical field changes, resulting in poor video quality and missing shooting records. At the same time, the ceiling-mounted surgical video recording equipment is fixed on the top of the operating room or on the shadowless lamp, and cannot be carried to other operating rooms for use. The cost of configuring a set of video recording equipment in each operating room is high and causes waste of resources. Head-mounted surgical video equipment has good portability and high mobility, but the angle of view is often in a shaking state with the movement of the surgeon's head when recording, and the stability is poor, so it cannot shoot high-quality surgical videos.

Therefore, the problem of how to provide a camera adjustment mount that can meet the aseptic principle of surgery and has both stability, flexibility and portability needs to be solved urgently.
