ZEISS STN System with IGS 2 cameras + manuals ZEISS Surgical Navigation System with STN (Surgical Tool Navigator) System and IGS (Instrument Guiding System) This Zeiss Surgical Navigation System comes with the STN (Surgical Tool Navigator) System and IGS (Instrument Guiding System). The STN and IGF systems comes with its own localize camera towers. The pictures provided will show all surgical attachments to the system and it also comes with an operation manual. Although, this system is mostly used in Neurological procedures the system would be a valuable tool for any surgical procedure. In fact BrainLAB uses the IGS for total hip replacement procedure. The system will be beneficial to surgeons that prefer to know exactly where to go prior to making the incision. The 3D images that this system produces are very accurate and it could be rotated on all direction to give the surgeon optimal mapping information. The system enables the operator to map out the procedure by using some of the features which includes the ability to place guiding marks, change color and highlight specific areas and we have included pictures that shows the system in action. The computer hardware on this system is well ahead of its time and at the time it was built the hardware alone justifies the half a million plus price tag that Zeiss sold it for In the field of neurosurgery, ophthalmology and ENT the Zeiss brand is synonymous to medical devices that incorporates the innovative use of cutting edge technology with extreme reliability. The Surgical Tool Navigator system was developed by Carl Zeiss for the purpose of providing the surgeon with greater safety and reliability. The STN processes data collected to produce with millimeter accuracy a 3D model of the patients brain and (as shown in the second picture the exact spot) of the cyst. STN is particularly suitable for surgical procedures requiring the stereotactic guidance of surgical instruments. The instrument is displayed as a virtual pointer on the workstation monitor screen. In the diagnostic images, the tip of this pointer marks the position of the tip of the instrument in the surgical field. The screen also displays additional information to help the surgeon operate the STN system. A pointer is used for referencing the orientation. The pointer consists of a grip with a tip. A Patient Tracking System tracks the movements of the patient and takes these movements automatically into account when computing and displaying the screen pointer. A stereotactic surgical planning system, which has been specially adapted to the STN system, is installed on the workstation. This system allows stereotactic surgical planning using diagnostic data (e.g. CT or MRI). The planning data obtained in this way is used by the surgeon during surgery as orientation and navigational aids for the stereotactic guidance of the surgical instruments. To be able to indicate the position of the instrument in the diagnostic image, the coordinate system of the surgical field must be correlated with the internal coordinate system of the instrument. Reference points (markers) adhered to the patients skin or screwed into the patients bones are used for this purpose. Prominent anatomical structures can also be used as markers, e.g. the spinous process of a vertebra. These reference points are then measured during planning prior to surgery. At the beginning of the surgical procedure, one reference marker after another is probed with the tip of the pointer. A localizer camera receives the encoded infrared signals emitted by the pointer. In this non-contact procedure, the workstation determines the position of the reference marker in space and correlates the diagnostic images with the respective structure in the surgical field. Additional reference points can also be defined during surgery. The STN system is easy to use. All the major functions can be controlled during the operation via a hand control panel which can be covered with a sterile protective sleeve. This permits all the navigation functions to be performed under sterile conditions. The price we are asking for this unit is less than some replacement parts. As such this unit would be great for hospitals that own an STN because they can use it as a backup and/or parts for their existing STN. It would also be a very good investment for Biomed companies that have clients who own an STN. Money Order/Cashier's Check, Personal Check |
