Anesthesia operation puncture needle with diversion groove

Abstract

The invention discloses an anesthesia operation puncture needle with a diversion groove. The puncture needle consists of a needle file, a needle tube and a needle tip, wherein the needle file is arranged at the upper end of the needle tube; the needle tip is arranged at the lower end of the needle tube and is conical; the sharp part of the conical needle tip is in a closed round head shape; the diversion groove is longitudinally punched on the outer wall of the upper needle tube of the needle tip; a plurality of drainage holes are formed in the diversion groove; the drainage holes are communicated with the inner cavity of the needle tube; and the number of the diversion groove is at least one and at most four. The needle tube of the puncture needle is provided with the diversion groove and the drainage holes, so that the lingering space of medicaments in muscle tissues is increased, the contact area of the medicaments and the muscle tissues is enlarged, the absorption capability is improved, the injection operation time is shortened, and the muscle tissues can be prevented from blocking the drainage holes; and the needle is designed in a conical shape, so that cutting injury to the muscle tissues or blood vessels due to the conventional needle in the puncture process is avoided, bleeding quantity is reduced, and postoperative healing is quickened.

Description

Technical field: [0001] The invention relates to a medical instrument, in particular to a puncture needle for anesthesia operation with a diversion groove. Background technique: [0002] At present, local infiltration anesthesia is usually used in cosmetic plastic surgery for facial wrinkle removal, liposuction or filling warming; and when liquid materials are used for soft tissue filling, the liquid also needs to be injected into the soft tissue. Both infiltration anesthesia and injection of liquid soft tissue filling materials require the use of injection techniques. This injection technique uses traditional injection needles to puncture repeatedly in soft tissues, so that the liquid can be evenly injected into the surgical area. The deficiencies in the existing technology are: the needle points of traditional needles are all single holes, and the front end is ground into a beveled point. When using traditional injection needles to puncture repeatedly in skin tissue, it i...

AI Technical Summary

Problems solved by technology

The deficiencies in the existing technology are: the needle points of traditional needles are all single holes, and the front end is ground into a beveled point. When using traditional injection needles to puncture repeatedly in skin tissue, it is easy to cause serious damage to blood vessels and nerve tissues. Single-hole injection with oblique hole at the tip of the needle, slow injection speed, and long anesthesia operation time, which not only increases the pain of the patient, but also increases the labor intensity of the medical staff
