技术领域technical field
本实用新型涉及阻滞针技术领域，具体为一种改良的神经阻滞针。The utility model relates to the technical field of blocking needles, in particular to an improved nerve blocking needle.
背景技术Background technique
在疾病诊疗领域，神经阻滞针被广泛用于偏瘫、肌体感觉障碍、关节病痛等疾病的治疗，此外在实施外周神经阻滞麻醉时，神经阻滞针还可用于准确确定麻醉位置。超声引导下的阻滞针可清晰地分辨血管、神经、肌肉组织、穿刺针位置，并在可视条件下直接阻滞神经，且有利于观察神经周围结构和动态观察麻药的扩散情况，提高神经阻滞的准确性和成功率，减少操作相关的血管和神经的损伤。In the field of disease diagnosis and treatment, nerve block needles are widely used in the treatment of hemiplegia, body sensory disturbance, joint pain and other diseases. In addition, when performing peripheral nerve block anesthesia, nerve block needles can also be used to accurately determine the anesthesia position. The blocking needle under the guidance of ultrasound can clearly distinguish the position of blood vessels, nerves, muscle tissue, and puncture needles, and directly block the nerves under visual conditions, and it is beneficial to observe the structures around the nerves and dynamically observe the diffusion of anesthetics, and improve the nerve function. The accuracy and success rate of the block can reduce the damage of blood vessels and nerves related to the operation.
根据申请号为202122126629.9的一种改良的神经阻滞针，其中使用时首先将斜面针管型针芯的针头端扎入患者皮肤内，斜面针管型针芯在距离神经有一段距离时，将限位块从而限位件中拆卸，从而拔出限位块，限位块移动从而将斜面针管型针芯从阻滞针中抽出，此时，利用阻滞针继续行进，阻滞针扎入对应的位置后，此时关闭阀门组件，从注射管内注射麻醉药物，因为阀门组件的设计使得麻醉药物从阻滞针针头位置进入到指定位置，从而完成麻醉。According to an improved nerve block needle with the application number 202122126629.9, when using it, the needle end of the beveled needle core is first inserted into the patient's skin, and when there is a certain distance from the nerve, the beveled needle core will limit The block is disassembled from the stopper, so that the stopper is pulled out, and the stopper moves to extract the beveled needle tube core from the blocking needle. After the position, the valve assembly is closed at this time, and the anesthetic drug is injected from the injection tube, because the design of the valve assembly allows the anesthetic drug to enter the designated position from the block needle needle position, thereby completing anesthesia.
然而，上述神经阻滞针在使用时存在一定的缺陷，该装置在使用穿刺过后需要将针芯拔出，在拔出过后阀门组件未关闭前阻滞针内部便与外界贯通，极易会出现血液回流流出的情况出现，这样便会将阻滞针污染，稍有不慎便会出现交叉感染的情况，另外，将针芯拔出过后针芯暴露在外，医护人员若是不慎被划伤，也会出现交叉感染的情况出现，使用较为不便，为此，我们提出了一种改良的神经阻滞针。However, there are certain defects in the use of the above-mentioned nerve block needles. After the device is punctured, the needle core needs to be pulled out. After pulling out, the inside of the block needle is connected to the outside before the valve assembly is closed. Blood backflow occurs, which will contaminate the blocking needle, and cross-infection will occur if you are not careful. In addition, after the needle core is pulled out, the needle core is exposed. If the medical staff is accidentally scratched, There will also be cross-infection, which is inconvenient to use. For this reason, we propose an improved nerve block needle.
