Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to an anesthesia puncture needle.
Background
Anesthesia means that a patient temporarily loses his or her feeling wholly or locally by medication or other means to perform surgical treatment for the purpose of painlessness. Anesthesiology (anesthesiology) is a science that applies basic theory, clinical knowledge and technology about anesthesia to eliminate operation pain of patients, ensure patient safety and create good conditions for operations.
At present, patient all needs anesthesia before doing the operation clinically, need the more accurate location of doctor ability during the injection anesthesia, and there is very big restriction to the inserted degree of depth of syringe needle, in case the mistake takes place probably endangers patient's life at any time, and increased very big work difficulty for medical staff, in addition, the position of being connected at the needle tail and syringe is plastics, in the epidural puncture operation in-process, a lot of anesthesia doctors are used to and are connected the syringe with the pjncture needle and puncture well before not reaching the ligamentum flavum, the benefit of doing so is: on one hand, saline can be injected into the injection to timely sense whether the injection reaches the ligamentum flavum and the epidural space; on the other hand, the connection of the injector is equivalent to lengthening the part which can be held by the puncture needle, and the puncture stability is increased.
Most of the current intravertebral anesthesia is still a blind probing operation, so that the situation that the puncture is difficult inevitably occurs. Even a highly experienced anesthesiologist may not be able to guarantee one hundred percent success of the puncture. This means that there is a possibility that a long-time puncture or repeated punctures may occur. However, the puncturing process may cause the needle tail to suddenly split, which makes it difficult for the anesthesiologist to: the needle is not changed, which means that the puncture difficulty is increased suddenly; the needle replacement means that the puncture bag needs to be replaced, which not only increases the pain of the patient, but also increases the economic burden of the patient, and the reason for the phenomenon is that the acting force on the needle tail is enhanced due to long-time puncture or repeated puncture, so that the needle tail is burst.
