Patent number: 11897129Abstract: A robotic system, such as a continuum robot, that includes at least one hollow tube backbone and an equilibrium modulation wire at least partially positioned within the backbone. The robotic system is configured to adjust a position of an end effector by bending the hollow tube and to further adjust the position of the robotic device by adjusting a linear insertion position of the equilibrium modulation wire inside the hollow tube, wherein adjusting the linear insertion position of the equilibrium modulation wire changes a flexural rigidity of the hollow tube resulting in a change in the resulting bending angle of the robotic device.Type: GrantFiled: February 26, 2021Date of Patent: February 13, 2024Assignee: Vanderbilt UniversityInventors: Nabil Simaan, Giuseppe Del Giudice, Long Wang, Karen M. Joos, Jin-Hui Shen

Patent number: 9757038Abstract: A miniature intraoperative probe (30) capable of forward-imaging with optical coherence tomography. The probe includes a housing (130), an actuator (150) supported by the housing, and a single mode (146) fiber supported by the housing and configured to laterally scan light data reflected from a sample.Type: GrantFiled: May 31, 2011Date of Patent: September 12, 2017Assignee: Vanderbilt UniversityInventors: Karen Joos, Jin Hui Shen

Patent number: 9014788Abstract: 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.Type: GrantFiled: February 18, 2014Date of Patent: April 21, 2015Assignee: Vanderbilt UniversityInventors: Karen Joos, Jin Hui Shen, M.

Patent number: 6458120Abstract: 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.Type: GrantFiled: August 17, 2000Date of Patent: October 1, 2002Inventors: Jin Hui Shen, Karen M. Joos
