Abstract

The utility model discloses an anesthesia puncture needle. 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; the needle tip is conical; the point part of the conical needle tip is in a closed round head shape; one to four diversion grooves are longitudinally punched on the outer wall of the needle tube on the upper part of the needle tip; a plurality of drainage holes are formed in each diversion groove; and the drainage holes are communicated with the inner cavity of the needle tube. The needle tube of the puncture needle is provided with the diversion grooves and the drainage holes, so that the resident space of medicaments in muscle tissues and the contact area between the medicaments and the muscle tissues are enlarged, the absorption capability is improved, the injection time is shortened, and the muscle tissues can be prevented from blocking the drainage holes; and the needle head is conical, so the cutting injury of the conventional needle head on the muscle tissues or blood vessels in the puncture process is avoided, the bleeding quantity is reduced and the postoperative healing time is shortened.

Description

A kind of anesthesia surgery puncture needle

Technical field:

This utility model relates to a kind of medical apparatus and instruments, specifically a kind of anesthesia surgery puncture needle.

Background technology:

At present, when the operations such as drainer for plastic surgery carries out that face crinkle-removing, liposuction or filling are warmed up, usually adopt local infiltration anesthesia; And when adopting liquid material to carry out soft tissue filling, also need liquid infusion in soft tissue.Infiltration anesthesia and injection liquid soft tissue filler all need to use injection technique.This injection technique is by traditional injection needle repeated localised puncture in soft tissue, makes being expelled in the operative region of uniform liquid.The deficiency that prior art exists is: the needle point of traditional syringe needle is single hole, front end is worn into the inclined-plane point, use traditional injection needle in skin histology during repeated localised puncture, easily cause the major injury of blood vessel, nervous tissue, and only utilize the inclined hole single hole injection of injection needle tip, and injection speed is slow, and the anesthesia surgery operating time is long, not only increase patient's misery, also increased medical personnel's labor intensity.

Summary of the invention:

The purpose of this utility model realizes in the following manner, comprise needle stand, needle tubing and needle point, needle stand is arranged on the upper end of needle tubing, needle point is arranged on the lower end of needle tubing, needle point is conical, and the tip of needle point is the round end shape of sealing, and the top vertical punching press of needle tubing outer wall of epiconus has guiding gutter, have several outages in the guiding gutter, outage communicates with syringe intracavity; Guiding gutter at least one, maximum four roads.

The beneficial effects of the utility model are: the needle tubing at traditional entry needle arranges guiding gutter and outage, the staying space of medicine in muscular tissue and the contact area of increase and muscular tissue have been increased, improved absorbability, shortened the injection operation time, can also avoid muscular tissue to the obstruction of outage, syringe needle is designed to coniform, avoided traditional syringe needle cutting damage to muscular tissue or blood vessel in piercing process, reduce amount of bleeding and quickening postoperation recovery time, this entry needle also has simple in structure, low cost of manufacture, easy for operation, save time, laborsaving, the characteristics such as safety.

The specific embodiment:

By reference to the accompanying drawings the anesthesia surgery puncture needle with guiding gutter of the present utility model is described in further detail:

Anesthesia surgery puncture needle with guiding gutter of the present utility model, its structure is comprised of needle stand 1, needle tubing 2 and needle point 5, needle stand 1 is arranged on the upper end of needle tubing 2, needle point 5 is arranged on the lower end of needle tubing 2, needle point 5 is conical, and the tip of needle point 5 is the round end shape of sealing, and the vertical punching press of top needle tubing 2 outer walls of cone tip 5 has guiding gutter 3, have several outages 4 in the guiding gutter 3, outage 4 communicates with needle tubing 2 inner chambers.

Guiding gutter 3 at least one, maximum four roads.

The length of guiding gutter and the quantity of outage are decided on the length of needle tubing.

Use puncture needle operating procedure of the present utility model as follows:

Be ready to operative region, at first use with the common syringe needle of piercing needle same diameter and do the skin hole making drill, with the skin puncture.Then, in the position of skin puncture puncture needle of the present utility model is inserted skin, carry out fan-shaped repeated localised puncture subcutaneous, with the operative region that is expelled to of uniform liquid.

Puncture needle of the present utility model can effectively be avoided or reduce organizing interior blood vessel, nerve, vasculolymphatic damage; Can be fast with reaching uniform effect in the tissue of liquid infusion in the field of operation, increase substantially operation efficient, reduce operating time, reduce medical personnel's labor intensity.
