Abstract
The utility model relates to a modified needle of an anesthesia syringe, which belongs to a medical appliance for anesthesia operation in a surgical operation and operation that liquid is ejected to be filled in soft tissues. In the utility model, the front end of the original hollow needle is closed as a blind end, and the surface of the blind end is a spherical surface; at least two eyelets are evenly and symmetrically arranged on the side of the blind end. When the needle of an anesthesia syringe is used, a hole is stabbed on skin through stabbing tools (such as an ordinary needle or a special skin dibber) with the same caliber at first, then the needle of an anesthesia syringe is inserted through the hole. After repeated stab in a fan shape, the liquid is evenly ejected into an operative region. Compared with the original needle of an anesthesia syringe, the design of the blind end and the spherical surface of the modified needle of an anesthesia syringe can avoid and reduce damage to blood vessels, nerves and lymphatic vessels in tissues at the time of repeated stab. The eyelet design on the side of the blind end can quickly make the liquid ejected to the upper and the lower parts, the right and the left parts of the tissues to obtain uniform infiltrating effect.
Description
This utility model relates to a kind of improved anaesthetic needle head, belongs to the surgical operation anesthesia procedure and with a kind of medical apparatus and instruments in the liquid infusion filling soft tissue manipulation.
At present, when the beauty and shaping surgery carries out operation such as face crinkle-removing, suction lipectomy, adopt local infiltration anesthesia usually; And when adopting liquid material to carry out the soft tissue plombage, also need liquid infusion in soft tissue.Infiltration anesthesia and the liquid soft tissue filler of injection all need to use injection technique.This injection technique is by general injection needle repeated localised puncture in soft tissue, makes liquid be expelled to operative region uniformly.Existing problem is: common syringe needle (syringe needle can be grown, can lack, and needle point is single hole, and front end is sharp-pointed) is repeated localised puncture in tissue, causes the damage to blood vessel, nerve; Because of being the single hole injection, speed is slow, and the anesthesia procedure time is long.
The purpose of this utility model is to provide a kind of improved anaesthetic needle head, so that in anesthesia and liquid soft tissue filling operation, when carrying out large tracts of land repeated localised puncture injecting fluid, avoids or reduces damage to tissue.Improve injection speed, reduce the anesthesia procedure time.
This utility model provides a kind of improved anaesthetic needle head, and it is made up of hollow pinhead, standard injector for medical purpose interface, and the front end of described syringe needle is a cecum, and the cecum surface is sphere; The cecum side evenly, be arranged with at least two eyelets.
Accompanying drawing is this utility model structural representation.
Description of drawings: 1 syringe interface, 2 hollow pinheads, 3 eyelets, 4 cecums.
Below in conjunction with accompanying drawing this utility model is elaborated: as shown in drawings, the syringe needle front end is provided with six eyelets, and the cecum surface is the ball face.Use: be ready to operative region, the Centesis instrument (as common syringe needle or special-purpose skin card punch) of at first using identical bore is with the skin puncture.Then, insert this utility model, carry out segmental repeated localised puncture, liquid is expelled to operative region uniformly subcutaneous by this hole.
Based on sphere design and lateral a plurality of eyelet on cecum of the present utility model, surface, can avoid or reduce organizing interior blood vessel, nerve, vasculolymphatic damage; Can with the liquid fast injection to the tissue about, about, reach effect of uniform.
