OmniVision Technologies, in collaboration with Myriad Fiber, has developed what the partners are calling the medical industry’s first commercial prototype for an endoscopic surgery tool with built-in camera. This reference design retrofits off-the-shelf endoscopic forceps with OmniVision’s ultra-compact OVM6948 CameraCubeChip camera module with built-in wafer-level optics. The concept is also ready to be implemented in a wide variety of other surgical tools, including scissors, suction devices, pliers and clippers.
This new prototype solves a real problem that surgeons face when performing endoscopic procedures—such as those for ear-nose-throat, urology and women’s health—which represent a growing percentage of all surgeries. The CMOS camera at the distal tip of today’s standard endoscopes is spatially offset and set behind the working channel through which the endoscopic surgery tool is passed. Setting up the camera as such can obstruct the surgeon’s view of the target region, provide an image with a shadow or even provide a misleading view of the tool. This lengthens the time required for surgery, causes more patient discomfort and complications, and creates the risk of an incomplete therapeutic procedure. In this prototype, the OVM6948 is incorporated directly into the tool, resolving the above-mentioned imaging issues encountered in more traditional setups.
OmniVision’s small medical camera modules, such as the OVM6948, are suited to this application. It includes a CMOS image sensor and built-in wafer-level lens, and comes in a 0.58 x 0.58mm package. OmniVision’s OmniBSI+ pixel architecture delivers best-in-class image quality, with a resolution of 200 x 200 at 30 frames per second. Low power consumption keeps the endoscopic tool cool, contributing to greater patient comfort. The OVM6948 can also be sterilized for disposable devices and is tested for bio-compatibility.
