Abstract
The utility model provides a porous needle for anesthesia, which comprises a needle rod, a connector, a wedge-shaped needle head and a plurality of needle holes on the wedge-shaped needle head. The porous needle for the anesthesia is characterized in that at least two needle holes are arranged on the needle rod, and the needle holes on the needle rod are communicated with the cavity of the needle rod and are uniformly arranged in a staggered way on the wall of the needle rod close to the end with the needle head. During local anesthesia, medicine for the local anesthesia can be injected directly through one-time puncture and can then be dispersed into surrounding tissues of a human body, rapid absorption and good anesthetic effect can be achieved, the time can be saved, and the pains of pregnant women can be reduced. When the diameter of the needle holes on the needle rod is 0.2-0.4mm and 4-8 needle holes are arranged on the needle rod, the medicine for the local anesthesia can be injected directly through the one-time puncture and can then be dispersed into the surrounding tissues of the human body, the defect of pulling out the needle during injection can be overcome, rapid absorption and good anesthetic effect can be achieved, the time can be saved, and the pains of the pregnant women can be reduced.
Description
Technical field
This utility model relates to a kind of anesthetic needle, belongs to technical field of medical instruments, is a kind of anesthesia porous pin specifically.
Background technology
The puncture needle that uses during the capable both sides of department of obstetrics and gynecology perineum side cutting pudendal block anesthesia for many years is the single hole minute hand always, want repeated localised puncture during the row local infiltration anesthesia, and need limit drawn needle marginal not to penetrate local anaesthetics, increased damage and painful to the anemia of pregnant woman during use, make troubles for simultaneously vast midwives.
Summary of the invention
This utility model provides a kind of anesthesia porous pin at the problem that prior art exists, and only needs pin puncture direct injection local anaesthetics just can make anesthetics be dispersed to surrounding tissue during the row local anaesthesia, absorb fast, anaesthetic effect is good, both saves time, and alleviates anemia of pregnant woman's misery again.
The purpose of this utility model is achieved through the following technical solutions:
A kind of anesthesia porous pin comprises the pin hole on shank, joint, wedge syringe needle, the wedge syringe needle, it is characterized in that: 2 pin holes are set on the described shank at least, and the pin hole on the shank communicates with the shank chamber.
To improvement of the technical scheme: the pin hole on the described shank near on the shank wall of syringe needle one end evenly and be staggered.
To further improvement in the technical proposal: the pinhole diameter on the described shank wall is identical with shank intracavity diameter.
To further improvement in the technical proposal: the pin hole axis on the described shank wall and the axis normal in shank chamber.
To further improvement in the technical proposal: the pinhole diameter on the described shank is 0.2～0.4mm, and quantity is 4～8.
This utility model advantage and good effect compared with prior art is:
Only need pin puncture direct injection local anaesthetics just can make anesthetics be dispersed to the surrounding tissue gap during use, overcome the disadvantage that limit drawn needle marginal not is penetrated, absorb soon, anaesthetic effect is good, both saves time, and alleviates anemia of pregnant woman's misery again.
Description of drawings
Fig. 1 is the front view of this utility model anesthesia with the porous puncture needle.
The specific embodiment
Referring to Fig. 1, a kind of embodiment that anaesthetizes with the porous puncture needle of this utility model comprises the pin hole 5 on wedge syringe needle 1, shank 2, joint 4, the wedge syringe needle 1.Even and a plurality of pin holes 3 that are staggered on the close shank of syringe needle one end, the pin hole 3 on the shank 2 communicates with the shank chamber.
During use, pin puncture back direct injection local anaesthetics, medicine enters the tissue except the main pin hole 5 on being positioned at wedge syringe needle 1, and medicine also is dispersed to tissue on every side from encircling rich being distributed near a plurality of pin holes 3 on the shank 2 of syringe needle 1 one ends simultaneously.This has just overcome the disadvantage that limit drawn needle marginal not is penetrated, and absorbs soon, and anaesthetic effect is good, both saves time, and alleviates anemia of pregnant woman's misery again.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and this utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of having done, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
