Anti-blocking anesthetic puncture needle for gynecological operation

Abstract

The invention discloses an anti-blocking anesthetic puncture needle for gynecological operation. The anti-blocking anesthetic puncture needle for the gynecological operation comprises a needle tube; abottom cover is arranged on the inner wall of the left side of the needle tube; the inner wall of the bottom cover is connected with the outer wall of the needle tube; a push handle is arranged on the inner wall of the bottom cover; the outer wall of the push handle is in lap joint and connection with the bottom cover; and a medicine bag is arranged on the inner wall of the needle tube. Accordingto the anti-blocking anesthetic puncture needle for the gynecological operation, the medicine bag and a liquid guide tube are fixed in the needle tube through cooperation of the needle tube, the medicine bag and the back cover under the action of the push handle; the push handle rotates to push a push plate to drive a medicine liquid to be exported from the liquid guide tube; stable operating environment is provided; the defects that anesthetic is overflow towards the outside when not entering the affected part to cause waste, medical workers still need to operate repeatedly and work fatigueis liable to generate are overcome; the operative treatment step of the medical workers is simplified; the work fatigue generated in the operation process of the medical workers is overcome; the working efficiency is improved; and the anti-blocking anesthetic puncture needle for the gynecological operation is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an anti-blocking anesthesia puncture needle for gynecological surgery. Background technique [0002] At present, in the process of physical examination or operation for puerpera and pregnant women, in order to relieve the pain of puerpera, it is often necessary to use anesthesia for surgery, but the obstetrics and gynecology anesthesia syringes in the prior art generally have large volume, short nozzles, A series of defects such as single spray angle and uneven atomization have seriously affected the treatment process and effect of the puerpera, and spinal tap anesthesia will have a certain impact on the baby in the puerpera. In order to better anesthetize the puerpera, In the field of gynecology, cervical anesthesia generally adopts syringes to directly anesthetize women's cervix, so that the anesthetic injected into the cervix can only anesthetize its wall locally, and ...

[0002] At present, in the process of physical examination or operation for puerpera and pregnant women, in order to relieve the pain of puerpera, it is often necessary to use anesthesia for surgery, but the obstetrics and gynecology anesthesia syringes in the prior art generally have large volume, short nozzles, A series of defects such as single spray angle and uneven atomization have seriously affected the treatment process and effect of the puerpera, and spinal tap anesthesia will have a certain impact on the baby in the puerpera. In order to better anesthetize the puerpera, In the field of gynecology, cervical anesthesia generally adopts syringes to directly anesthetize women's cervix, so that the anesthetic injected into the cervix can only anesthetize its wall locally, and cannot achieve the purpose of anesthesizing the entire cervical wall. In the prior art , for example, the invention patent with application number 201120327206.7 includes a syringe, an anesthesia nozzle, and a nozzle cover. The anesthesia nozzle is long cylindrical, and the anesthesia nozzle is densely covered with numerous micropores, and the nozzle cover is wrapped on the anesthesia nozzle. Although the invention has a simple structure, there are many deficiencies and defects. In the equipment, there are defects in the design of the anesthesia nozzle. The anesthesia nozzle is easily blocked by body fluids or secretions when it is sent into the patient's body, which affects the anesthesia operation, and the length of the anesthesia nozzle cannot be adjusted so that the anesthetic can reach the affected area and affect the anesthesia effect. In addition, the way of pushing and injecting is easy to cause the anesthetic to be released too fast, causing the anesthetic to overflow outside without entering the affected area, resulting in waste, and the medical staff still need to operate repeatedly, which is easy to cause work fatigue. In view of these situations, in order to avoid the above technical problems, It is really necessary to provide a kind of anti-blocking anesthesia puncture needle for gynecological surgery to overcome the defects in the prior art
