Abstract
Purpose: Flexible fiber optic endoscopes are frequently used in gastroenterology to obtain tissue samples by making use of flexible biopsy forceps. Usually the biopsy forceps are transferred from the endoscopy assistant to the endoscopist to be inserted in to the biopsy channel of the endoscope. At this point the endoscopist will ask the assistant to open and close the biopsy forceps, withdraw the forceps to retrieve the specimen obtained, and the assistant will deposit the specimen in to the collection bottles. The endoscopist must use both hands to locate and maintain the distal tip of the endoscope adjacent to the site to be biopsied. Often multiple specimens from multiple sites are obtained. The assistant is responsible for monitoring patient's vital signs, and assistant's involvement in biopsy procedure will compromise the monitoring responsibilities. This two operator sequence can prolong the procedure and increase patient discomfort. Methods: We developed a foot operated endoscopy biopsy assist device that is operated and controlled by the endoscopist in its entirety and does not require any intervention from the endoscopy assistant. The device can be applied to any other endoscopic biopsy procedures. The device provides universal connection to any model of endoscopic biopsy forceps to the foot operated actuator prior to commencement of the procedure. The biopsy forceps is thus readily available for use by the endoscopist, who can independently access the forceps, open and close the distal jaws for tissue sampling by using the foot pedal actuator. The endoscopist can then transfer the tissue samples obtained through a guide funnel in to the specimen collection bottles which are pre-loaded on an indexed rotating platform on the biopsy assist device. Results: The device is fully developed and tested in real time by an experienced gastrointestinal endoscopist (author). The device completely frees the endoscopy assistant from any involvement in the biopsy procedure, enabling the assistant to focus on other aspects of patient care. Conclusions: Our invention, the endoscopy biopsy assist device, will revolutionize the biopsy procedure in gastrointestinal and other endoscopies. The reduced diagnostic procedure time will result in increased patient comfort. The self operation and freeing of the endoscopy assistant will result in better monitoring of the patient.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
