Lumbar puncture structure with accurate positioning capability

Abstract

The invention discloses a lumbar puncture structure with accurate positioning capability. The lumbar puncture structure with accurate positioning capability comprises a needle core with a hollow structure and a needle tube with a hollow structure; the needle core is arranged inside the needle tube, one end of the needle core is connected with a transparent cerebrospinal fluid observation window,the cerebrospinal fluid observation window is positioned outside the needle tube, an adjusting valve is arranged at the end, which is close to the cerebrospinal fluid observation window, of the needletube, and a waterproof breathable film is arranged at the end, which is away from the needle core, of the cerebrospinal fluid observation window; the end, which is away from the cerebrospinal fluid observation window, of the needle tube is provided with a hollow needle tip, the other end of the needle tube is provided with a cerebrospinal fluid pressure display, the needle tip is provided with anopening for the needle core to pass through, the end, which is close to the needle tip, of the inner side wall of the needle tube is provided with a pressure sensor, and the side wall of the needle tip is provided with a through hole. The puncture depth is detected through the pressure sensor, so that the puncture accuracy can be improved, multiple punctures are avoided, and the pain feeling of apatient is relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a precisely positioned lumbar puncture structure. Background technique [0002] Lumbar puncture is an indispensable examination and treatment method in the diagnosis of neurological diseases, spinal anesthesia, spinal drug administration, myelography, and cerebrospinal fluid drainage. At present, the traditional needle core is used clinically, that is, a single outer needle and needle core structure with an inner core, but this traditional needle core is difficult to control the flow of cerebrospinal fluid, and cannot stop the flow in time, which is easy to aggravate the patient's headache and cause cerebral palsy. It is also easy to cause infection; the puncture process depends entirely on the experience of the doctor, and the accuracy of the puncture cannot be guaranteed, which may lead to puncture failure, and the depth of the needle cannot be grasped during the op...

At present, the traditional needle core is used clinically, that is, a single outer needle and needle core structure with an inner core, but this traditional needle core is difficult to control the flow of cerebrospinal fluid, and cannot stop the flow in time, which is easy to aggravate the patient's headache and cause cerebral palsy. It is also easy to cause infection; the puncture process depends entirely on the experience of the doctor, and the accuracy of the puncture cannot be guaranteed, which may lead to puncture failure, and the depth of the needle cannot be grasped during the operation, which is likely to cause injury to the patient and increase the risk of medical accidents. Risk; and the measurement of cerebrospinal fluid pressure requires a traditional glass tube, which is not only inconvenient to operate, but also has the needle core shaking or even shifting during the measurement process, which may cause unnecessary damage to the patient, and the cerebrospinal fluid pressure cannot be displayed in real time during the release of cerebrospinal fluid , which may cause hypotension headaches and even brain herniation due to over-release
