A miniature intraoperative probe () capable of forward-imaging with optical coherence tomography. The probe includes a housing (), an actuator () supported by the housing, and a single mode () fiber supported by the housing and configured to laterally scan light data reflected from a sample.

Optical coherence tomography probe

An optical coherence tomography probe and laser combination device configured for real-time z-directional guidance of the incisional depth of a surgical procedure. It can be used alone or placed within the working channel of an endoscope. The device includes an OCT single mode fiber, and a laser fiber or laser hollow waveguide or electrical surgical wire positioned adjacent to the OCT single mode fiber. The single mode fiber is configured to move laterally when activated by an actuator to scan light data reflected from a sample that is positioned in front of a distal end of the device. The light data can be processed to generate a B-scan image. The device can collect data in real-time during lasing, or immediately prior to and following the cutting. The surgical tool, when coupled to a processor, can deactivate when the B-scan image identifies that the incision is within a predefined tolerance.

Apparatus and method for real-time imaging and monitoring of an electrosurgical procedure

A surgical laser probe and system combines a laser diode array remotely connected to a hand-held surgical probe by a fiber bundle. The surgical probe includes a laser head which produces a laser beam for surgical tissue ablation that is delivered through a disposable intraocular probe tip. The probe tip is made of a short section of optical fiber. Preferably, the laser head is an Er:YAG rod pumped by energy from the laser diode array to operate at a wavelength of 2.94 microns. Auxiliary water and thermal electric cooling integral to the hand piece cools the laser head.
