Surgical Temperature Sensors from Amphenol

The effects of surgeries and anesthesia on thermoregulation by the human body have increased the need for monitoring temperature during these crucial procedures.

Some common examples of temperature monitoring include the measurement of myocardial temperature during open-heart surgery, cell temperature during laser ablation, or the laser surgical device itself for improved performance and patient comfort.

How does Amphenol Help?

Amphenol Advanced Sensors offers a wide range of tiny chip-in-glass or sleeved chip thermistors with fine diameter wires for external attachment to metal lumens used at the time of laser surgery or for insertion into hypodermic needles used for myocardial surgeries.

The interchangeable NTC chip thermistors types MA, SC and A040 from Amphenol have been designed with compact packages to facilitate quick response, while maintaining excellent precision.

Amphenol Advanced Sensors can integrate the NTC thermistors into user-specific designs, thus offering rugged construction and ensuring a prolonged life in adverse clinical settings. This combination facilitates the assembly to realize a precise temperature, delivering important diagnostic data.

Application Example: Cosmetic Laser Surgery

  • Laser inserted under skin employs heat to discharge the fiber spans that pull down on the skin to produce a smoother look
  • The thermistor feedbacks temperature to modify the laser energy for a more efficient process and improved patient comfort.
