Instrumentation Amplifier

Instrumentation Amplifier

An electrocardiography (ECG) machine is an essential piece of medical equipment used to monitor the electrical activity of the heart. It operates by detecting small electrical changes on the skin that result from the depolarization of the heart muscle during each heartbeat. However, these signals are in the microvolt range and can be easily overwhelmed by noise or interference.
To overcome this challenge, an ECG machine utilizes an instrumentation amplifier. This specialized amplifier is...

Background:

Cochlear implant (CI) surgery aims to restore hearing in individuals with severe to profound hearing loss.
Electrode array (EA) insertion is a critical step in CI surgery, with hearing preservation being a key surgical goal.
Robotic-assisted surgery offers potential advantages in precision and control during delicate procedures.

Purpose of the Study:

To evaluate the effectiveness of robotic-assisted electrode array insertion in preserving hearing after cochlear implant surgery.
To compare hearing preservation outcomes between robotic-assisted and manual EA insertion techniques.

Main Methods:

A cohort study comparing 24 patients undergoing manual EA insertion with 27 patients receiving robotic-assisted EA insertion (iotaSOFT system).
The primary outcome was low-frequency pure-tone average (LFPTA) measured at multiple time points up to 1 year post-surgery.
Functional acoustic hearing was defined as LFPTA < 80 dB HL.

Main Results:

85% of patients in the robotic-assisted group maintained functional acoustic hearing at 1 year, compared to 71% in the manual group.
While the difference was not statistically significant (p=0.31), robotic-assisted insertion showed a trend towards better hearing preservation.
The number needed to treat with robotic assistance to prevent one additional loss of functional hearing was 7.

Conclusions:

Robotic-assisted EA insertion is associated with improved hearing preservation in cochlear implant surgery over a 1-year period.
Preserving hearing is crucial for enhanced CI outcomes, and robotic assistance supports this objective.
This technology represents an advancement in cochlear implant surgery for optimizing hearing preservation.
