A surgical system combines a cannula and an instrument in a manner that allows small gauge instruments to be used effectively, with little or no bending with respect to the manipulating proximal side of the instrument. Such design overcomes the shortcomings of prior art, and applies to various microsurgical procedures, including ophthalmology, allowing the use of smaller endo-photocoagulation probes, illumination probes, combination probes, vitrectors, scissors, manipulators, picks, diathermy, and others. By using smaller gauge, patient recovery is expected to be faster.

Small gauge instruments for micro surgery

A probe for endo-ocular photocoagulation procedures provides straight and curved tip configurations. A flexible tubular material, pre-formed with a radius of curvature, allows the tip to be inserted through a trocar cannula and to resume its pre-formed shape for use during a surgical procedure. Alternatively, a tubular material is pre-formed with a radius of curvature, and is stiffened by use of a preferably stainless steel tube. Inside the tubular material is a distal end of at least one optical fiber, inserted such that its tip is coterminous with the tubular material. A tube surrounds the optical fiber and is free to move along the axis of the assembly, acting to straighten the tubular and optical fiber members as it moves forward via a sliding member associated with the hand piece. Illumination energy, laser energy, or both may be supplied to the targeted surgical site.

Probes for use in ophthalmic and vitreoretinal surgery

An illumination and laser energy delivery system, including an extended tip laser and illumination probe for retinal surgery, is disclosed that allows efficient delivery of laser and illumination energy to a surgical site through a device that is smaller than the standard 20 gauge probe conventionally used in endo-photocoagulation procedures. Novel constructions, as disclosed, enable the space inside the probe cannula to be used more efficiently than in prior art devices, providing improved performance of the device and system in delivering laser and illumination energy to the surgical site.

Extended tip laser and illumination probe for retina surgery

An ophthalmic surgical device is disclosed that combines laser energy for treatment of vision or ocular defect and illumination energy for visualization of a treatment site during surgery in a single common waveguide fiber, thereby enabling reduction of a diameter of a probe or canula of the device, whereby a smaller incision may be utilized to reduce trauma to the eye. The device may further include additional features, such as a conduit for supply of material or removal of material from the treatment site.
