A suction instrument for microsurgery.
Troublesome bleeding from small blood vessels occurs during operations on the cornea and sclera. The bleeding from the smaller blood vessels will stop spontaneously if given time, the larger vessels may need to be cauterized. The traditional way of dealing with the blood by mopping it up with cotton swabs or cellulose sponges has some disadvantages. The bleeding point and the surrounding area h...

متن کاملActive handheld instrument for error compensation in microsurgery
Physiological hand tremor and other manual positioning errors limit precision in microsurgical procedures. Our research has involved development of adaptive algorithms and neural network methods for real-time compensation of such errors. This paper presents a novel design for an active hand-held microsurgical instrument to implement these algorithms, particularly during vitreoretinal microsurge...
متن کاملForce Feedback of Dual Force-sensing Instrument for Retinal Microsurgery
Our project uses the Eye Robot to assist retinal microsurgery, a delicate procedure which requires force sensing at a level routinely less than 7.5mN. A tool with integrated fiber bragg grating sensors was manufactured for this purpose. An eye phantom that simulates the sclera forces and the peeling procedure was made to test the surgical system. This paper investigates on the same surgical pro...
متن کاملA Study of Instrument Motion in Retinal Microsurgery
This paper reports on high-precision recordings of hand-held instrument motion during actual vitreoretinal microsurgery. The movement of a hand-held instrument during vitreoretinal microsurgery was recorded in six degrees of freedom. Data were acquired for 5 min using an inertial sensing module that has been developed for use with a commercially available microsurgical instrument. Maximum veloc...
