摘要:
FIELD: medicine.SUBSTANCE: group of inventions relates to medical equipment, specifically to a soft-tip medical instrument for surgical ophthalmic procedures and the method of forming a soft-tip medical instrument for surgical ophthalmic procedures. Medical instrument comprises an elongated portion comprising a cannula or needle, comprising a distal end and a wall, and forming a first channel. Wall extends between the outer surface of the elongated portion and the first channel. Soft tip is attached to the peripheral edge of the distal end of the elongated portion at the grip point. Tip comprises a second channel equivalent in size to the first channel of the elongated portion. Gripping point is formed between the surface of the peripheral edge of the distal end of the elongated portion and the surface of the proximal end of the soft tip. Surface of the peripheral edge of the distal end of the elongated portion and the surface of the proximal end of the soft tip are in contact when the soft tip is connected to the elongated portion. Gripping point has a surface area larger than the cross-sectional area of the elongated portion, and is adapted to provide tongue and groove connection between the elongated portion and the soft tip. Moreover, tongue and groove connections comprise a tongue formed on said tip, and a groove formed on the elongated portion. Surface of the peripheral edge of the distal end of the elongated portion includes a reinforced surface. Reinforced surface comprises one or more of pores, channels, or textures that define an additional surface area at the gripping point for interacting with the soft tip. Method includes preparing the distal end of the elongated portion for attaching the soft tip, including laser cutting, water jet cutting, drilling, or a combination thereof, to form a groove in the distal end of the elongated portion, and attaching the soft tip to the peripheral edge of the distal end of the elongated portion, including casting, injec
