2 results about "Surgical probe" patented technology

A vitreous surgical probe includes: a probe body penetrating an eyeball; and a cutter blade sliding along the inner surface of the probe body, in which the probe body includes: a tubular portion with an opening in vicinity of a tip portion thereof; and a tip wall portion sealing the tip portion of the tubular portion, the tip wall portion is inclined such that a part located on the opposite side of the opening is toward a proximal side, and, in a second cross-sectional shape on a second plane passing through the central axis of the tubular portion and perpendicular to the first plane extending from a side of the opening to the opposite side of the opening, at least outer edges a of the tip wall portion are positioned on the proximal side.

The application relates to the technical field of ophthalmic microsurgery, and discloses an ophthalmic surgery capsule membrane incision system and method. Liquid light-sensitive conductive precursors are injected to the surface of the anterior lens capsule to conformally spread, a composite surgical probe is used to project a structured light spot, and the light-irradiated area is in-situ cross-linked and solidified into a hydrogel electrode ring; a multi-contact microelectrode array establishes physical contact with the hydrogel electrode ring, contact conformal impedance topology mapping is carried out, and a spatial impedance topology map is obtained; the system calculates and generates a spatial energy distribution matrix of multi-channel cutting energy according to the topology map, and finally releases transient high-frequency radio frequency pulses to the hydrogel electrode ring through the multi-contact microelectrode array to cut the anterior lens capsule. The application eliminates solid physical gaps by using material rheological characteristics, combines spatial differential energy distribution based on impedance feedback, and realizes uniform cutting without thermodynamic tearing.
