A retractable backflush instrument

Abstract

Certain embodiments provide a surgical instrument comprising a hand-piece, an outer tube having a proximal end coupled to a distal end of the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an actuator, and a valve housed inside the hand-piece and coupled to the proximal end of the actuator. Retraction of the actuator is configured to compress the valve and retract the soft tip into a distal end of the outer tube, such that the soft tip at least partially extends beyond the distal end of the outer tube when the valve is in an uncompressed state and at least partially retracts into the distal end of the outer tube when the valve is a compressed state.

Description

[0001] priority statement [0002] This application claims to be filed on December 12, 2018, and the inventors are Reto Grueebler, Thomas Linsi, and Philipp Schaller, and the title is "Squeezable 62 / 778,443 to A RETRACTABLE BACKFLUSH INSTRUMENT", the entire contents of which are hereby incorporated by reference as if fully and completely set forth herein. technical field [0003] The present disclosure generally relates to a retractable recoil instrument. Background technique [0004] Recoiling instruments are commonly used during surgery (e.g., ophthalmic surgery) to vacuum fluid (e.g., balanced salt solution (BSS), silicone oil, perfluorocarbon (PFC)) from a body part (e.g., a patient's eye) Come out or suck it out. For example, during certain ophthalmic procedures, recoil instruments may be used for fluid extraction, internal drainage of subretinal fluid, retinal fold manipulation, simultaneous or sequential exchanges (e.g., fluid-air, air-gas, fluid-gas, fluid -PFC, P...
