Surgical Microscope Camera

Product name: Surgical microscope Camera

Trade name: USB Microcam

Product Specifications: The Surgical microscope Camera has a video camera attached at the tip with lens assembly, lens holder, inner cylinder, focus ring, a video camera with 8 LEDs (light emitting diodes) for illumination and a stand for its holding and movement with a USB output. It has 200 X magnification with a side focus ring.

Detailed description: Complete specifications of the Surgical microscope Camera are: The device is tubular in shape and is made up of a lens assembly, lens holder, inner cylinder, focus ring, a video camera with LEDS for illumination and a stand for its movement. The stand has a base plate (figure:1B,13) with a vertical rod (figure:1B,9) with threads. (Figure:1B,12). A metal sleeve (figure:1B,10) moves up and down these threads (figure:1B,12) with 2 large screws. (Figure:1B,11) The sleeve has a bar with a ring (figure:1B,6) as a holder which holds the microscope. A small screw(figure:1B,5) fixes the microscope with the ring.

The device has an outer cylindrical shaped body. (Figure:1C,8) It has an inner cylinder (figure:2B,6 and figure:3,8) with groves(figure:2B,4) for the movement of the knobs of lens holder. Inside inner cylinder is a focus ring. (Figure:2A,1 and figure:2C,9 and figure:3,7) This focus ring (figure:2A,2) has groves from inside.

The front part of the microscope has a plastic cover (figure:1A,3 and figure:2C,7 and figure:3,16) to avoid outside light interfering in the microscope image. In the front part of the microscope, there is a ring (figure:3,15) with a central hole LEDS (figure:1A,2 and figure:3,14) for illumination.

The device has a cylindrical shaped structure containing lens assembly (figure:1A,1 and figure:3,17). It gives the it a reasonable magnification range.  There is a lens holder (figure:3,10) at the bottom of this cylinder. The lens holder has 4 knobs (figure:3,9 and 10) placed diagonally opposite to each other, out of which the 2 move in the groove (figure:2B,4) of the inner cylinder over 2 metal rods and another 2 are moved by the groove (figure:2A,2 and figure:3,9) of the focus ring. As the focus ring moves, the lens holder and the lens assembly move forwards and backwards giving a focus range of 4 to 50 cm.

Behind the lens, these is a video camera (figure:3,3) with a CMOS chip. (Figure:3,5) The image of the lens falls on the CMOS chip and converted into a digital signal. The body of the microscope has a button (figure:1B,7) for taking still pictures. The camera has a wire with USB output with a switch for light control that controls the brightness of LEDs in the front. A USB wire connects the device to variety of devices such as desktop, laptop, android mobile phones and android based tabs. The microscope comes with software which needs to be installed on display devices to see and record the images and the video.

 The technical advances of my invention are as follows. My Surgical microscope Camera has a tubular shape and is made up of a lens assembly, lens holder, inner cylinder, focus ring, a video camera with LEDs (light emitting diodes) for illumination and a stand for its holding and movement during surgery and a USB output. For operative recording, the distance of object from Surgical Camera should be 20 cm or more. There is image loss due to lenses. Due to Chip on the Tip technology, there is no image loss in my microscope. My microscope has a USB output as a male USB pin which connects to a USB cable that connects the device to the computer desktop, laptop, android device or a mobile phone and a free software given along the instrument installed on the display devices has a facility for display and recording of the video and images, a feature absent in prior art. My Surgical Camera can record a variety of operative procedures in Ophthalmology, Otolaryngology and in plastic surgery for microvascular surgery. Due to lack of above features, the prior art devices simply cannot be used as a replacement for my device. The prior art devices are imported and costly costing about Rs.2 Lakhs, whereas my device is cheap and indigenized and can be commercialized for only Rs. 30,000. My device is in tune with government of India’s Make in India policy.

Intended application: The surgical microscope camera is used for recording a variety of operative procedures in general surgery, paediatric surgery, Ophthalmology, Otolaryngology and in plastic surgery for microvascular surgery. For this purpose, a separate stand is necessary to hold the Surgical Camera in various positions. The device can be used as a digital microscope for microvascular surgery in plastic surgery, for microvascular surgery of tubal recanalization and for Vas Difference recanalization, for ear and ophthalmic surgery etc.
