STATEMENT OF NEED

ZEISS Tivato 700 Surgical Microscope GENERAL: ENT Surgery section of Surgical Service at the James A. Haley Veterans Hospital, has a requirement for a ZEISS Tivato 700 surgical microscope (brand name or equal). The microscope is needed for all inner ear and cochlear implant surgical procedures as well for throat surgical procedures. An older generation ZEISS SS8 microscope is currently being used.

BACKGROUND:

The current scope being utilized is about 12 years old and requires the use of a side co-observer tube and must be counterbalanced for each use. This co-observer tube provides the ability for either the attending surgeon or resident to view the surgical site through the microscope. The head of the microscope which includes the oculars and co-observer tube, has on occasion slipped out of balance and turn over when the clutch is released (the clutch allows the microscope oculars to be moved and float freely). But by turning over and not going into the ‘float’ mode, it could potentially cause permanent injury to the patient.

The current video system for this scope is obsolete in which it uses a camera adapter that is side mounted on the scope and a camera head is attached to it. This method frequently does not provide optimum viewing and is also difficult to focus the camera. This makes monitoring the resident tough as well as demonstrating the pathology. In addition, a video tower must be positioned near the microscope to plug in the camera head cable into the camera unit. With added equipment surrounding the surgical area, this creates a potential risk for contamination of the surgical field.

SCOPE: The Zeiss Tivato 700 microscope (brand name or equal) will be utilized for inner ear surgical procedures and throat surgical procedures completed by the ENT surgical service.

ESTIMATED QUANTATIES: The only consumables used with the microscope will be a microscope drape that is already in the O.R.’s inventory and is managed by MSDU.

SPECIFIC NEED/SALIENT CHARACTERISTICS/brand name or equal ZEISS Tivato 700 microscope to include the following:

Ent comfort package 1/ea Eyepiece 10x for all tubes Tiltable tube with eyepieces 1/ea Triled 1/ea Side co-observation with straight tube 1/ea Co-observation face-to-face stereo-bridge with tiltable tube 180°, 2x eyepieces and rotatable adapter supports assistance in spine/p&r surgery Premium HD video package fully integrated 3-chip HD camera, 1080p includes ODU-HDMI cable (5m) and HD-SDI cable (10m) Shipping crate (no solid wood) 1/ea Stereo co-observation tube w/ two joints 1/ea Straight binocular tube f=170mm 1/ea Widefield, push-in eyepiece 10x 1/ea Sleeve for push-in eyepiece 10x/12.5x 1/ea

The Zeiss Tivato 700 is the only microscope in the ENT market with the largest working distance, 200mm to 625mm. This provides the ability to position the microscope base further away from the surgical field, greatly increasing space around the surgical area. Other manufactures in the ENT market can only go up to a 500mm working distance. It also has an Active Vibration Damping that significantly, if not, eliminates vibrations during procedures after the repositioning of the visualization system and during small movements. Additionally, it has integrated 4K camera technology with a large external monitor that allows for easy viewing by the surgical staff and as previously discussed, this provides the surgeon to monitor the resident as well as demonstrating the pathology. This can be routed through the monitors suspended on the surgical booms throughout the surgical suite.

PERFORMANCE MONITORING: Proper training/in-service will occur for operating the ZEISS Tivato 700 microscope.

PLACE OF PERFORMANCE: James A. Haley Veterans Hospital, 13000 Bruce B. Downs Blvd, ENT Surgery - Operating Room, Bldg. 1, Tampa, FL 33612 DELIVERY SCHEDULE: Due to microscope being manufactured in Germany, 12 weeks should be allowed for delivery.

WARRANTY OF EQUIPMENT: The manufacture provides a standard warranty on OPMI microscopes of one-year parts and labor, commencing on date of installation.
