Introduction
Overview Purpose This manual describes how to operate the neo2000® Gamma Detection System (neo2000), which includes a control unit or console and a family of probes for detecting gamma radiation. Intended Use The neo2000 is an electronic device intended to detect and quantify gamma radiation. Indications The neo2000 is indicated for external and intraoperative detection of radioactivity in body tissues or organs, where radiopharmaceuticals are administered.

1.1 System Warnings, Cautions and Notes Overview Read this section before operating the neo2000®. Included below are operational warnings, cautions and notes for safe operation of the neo2000. Definitions Warning: Specific information provided to the user to advise of situations where the misuse or unlabeled use of the device could present potential harm to the user or patient and/or could result in irreparable damage to the device or property. Caution: specific information provided to the user to prevent the misuse of the device which may cause it to malfunction or produce erroneous readings. Note: general information provided to the user to further explain or clarify the proper operation of the device and/or its accessories.
Warnings • The reusable detector probe is a delicate surgical instrument. DO NOT DROP. Mechanical shock can result in irreparable damage. • Only properly trained and qualified personnel should use the system. • There are no user serviceable parts in the neo2000 - DO NOT OPEN. • The system is not to be used in the presence of flammable anesthetics or other explosive gases. • The neo2000 should only be cleaned after the power cord is disconnected from the console and the power outlet. • Do not sterilize or immerse the console as permanent damage may result. • Only Neoprobe approved accessory equipment shall be used with this device. Use of this device with unauthorized accessories may void the warranty with the user assuming all liabilities. • When using Model 1017 14mm probes with the neo2000 console, only use probes with serial numbers 1498600 or higher (gain-trimmed). Model 1017 14mm probes with serial numbers less than 1498600 (not gain-trimmed) are designed
and can be used with the Neoprobe 1500 console, but are not recommended for use with the neo2000 console. •Do not use Model 1002 19mm probes with the neo2000 console. The Model 1002 19mm probe is designed for use with the Neoprobe 1500 console, but is not compatible with the neo2000. • No component, part, or accessory can be autoclaved. Use only recommended cleaning and sterilization methods (see Chapter 4). • No component, part, or accessory can be gamma sterilized. Cautions • The system components should not touch other electrical equipment during use. • Use of this device in the vicinity of X-ray producing devices may cause false counts. • Electrocautery and other electrosurgical devices may interfere with the operation of the neo2000. If interference is observed in the presence of these devices, the user is advised not to operate these devices while the neo2000® is in operation. If this can not be done, move these devices away 1.1-1

1.1 System Warnings, Cautions and Notes (Continued) from the neo2000 to mitigate the effects of the electromagnetic interference. • If the neo2000 does not operate at all when the power is turned on, the user should check the user-accessible fuses on the back panel. The fuses should only be checked with the power cord disconnected from the neo2000 console. • Use of this device in the vicinity of persons undergoing radiation therapy may cause false counts. • The neo2000 has a radionuclide selection indicator for 18F, which has a photo peak energy of 511 keV. The 18F function is for future product development. For information on availability contact Neoprobe. • Always make sure probe connector pins and contacts are dry before use. Wet contacts may cause erroneous readings or operation.
Notes • Inspect Model 2024 and Model 2060 reusable cable for cracks or cuts before use; do not use if the cable is damaged. If a cable is cut during surgery, it should be replaced immediately. • Assure that reusable probes (Model 1017 and Model 2059, respectively) are securely attached to the reusable cables (Model 2024 and Model 2060) before use. • The system generates no hazardous radiation but is designed to detect various radioactive materials. When using radioactive materials, use safe and proper handling techniques. See your institution’s Radiation Safety Officer about Nuclear Regulation Commission and other requirements.
• Call Neoprobe Corporation immediately at 800-793-0079 or 614-793-7500 to report any incident or injury that occurred during use of the neo2000.

1.2 Definitions Overview This section defines symbols and key terms used in this manual. Words in bold are defined in this section.
Compton scattering Radioactive “noise” at an energy level lower than the photopeak of the injected radiopharmaceutical.
Count rate A continuous counting rate of gamma radiation measured in counts per second (cps) and updated every half-second. Count rate is shown on the same line of the console display as target count and target check when these functions are not activated.
Dynamic pitch range An operator-selected audible and counting range of radioactivity. If the count rate falls within the selected range, a variable-pitch sound is produced which is proportional to the level of gamma radiation present. Areas of tissue that generate higher pitch are associated with higher levels of radioactivity.
Background count In Binary Pitch mode: baseline value measured in counts per second (cps) that is stored by the system for comparison with the target count to determine if the difference in radioactivity between background tissue and target tissue is statistically significant. In Dynamic Pitch mode: a baseline value measured in cps that is stored by the system, and is used as the threshold at which the sound is activated.
Ratio A value indicating how likely it is that target tissue has been found (target count divided by background count).
Target count A number indicating the level of radioactivity detected by a probe as measured held stationary for 6 seconds over target tissue; more accurate than target check. The target count activates and displays ratio calculation.
Target check A quick check of the level of radioactivity measured in counts per second detected by a probe held stationary for 2 seconds over target tissue; more accurate than count rate. The target check function does not display a ratio calculation. 1.2-1
