Multi-target vertebral canal spinal needle and use method thereof

Abstract

The invention discloses a multi-target vertebral canal spinal needle and a use method thereof. The multi-target vertebral canal spinal needle consists of an outer tube needle and an inner tube needle which are in movable fit with each other, wherein the needle head of the outer tube needle is a spoon-shaped needle head; the back end of the outer tube needle is provided with a handle support and a faucet which is matched with the inner tube needle; the surface of the outer tube needle is provided with graduations; the needle head of the inner tube needle is an inclined-surface-shaped needle head; the side face of the inclined-surface-shaped needle head is provided with an outlet hole; the back end of the inner tube needle is a hand holding handle; the front end of the hand holding handle is provided with a nipple which is matched with the faucet of the outer tube needle; the back end of the hand holding handle is provided with a faucet which is matched with the head part of a microsyringe; and the inner tube needle is longer than the outer tube needle. During use of the multi-target vertebral canal spinal needle, cell leakage can be avoided, and cell resources are saved; multi-target injection can be performed by inserting the outer tube needle at one time, so that repeated insertion into different positions is avoided; the microsyringe is used for injecting, so that the dosage is accurate; and moreover, the multi-target vertebral canal spinal needle has biopsy and brain pressure measuring functions.

Description

technical field [0001] The invention relates to a spinal canal and spinal cord puncture needle for clinical use, which is mainly suitable for the puncture of cell transplantation in the bone marrow, and can also be used for taking biopsy samples for spinal cord lesions and measuring brain pressure. Background technique [0002] At present, because there is no puncture needle specially used for intraspinal cell transplantation clinically, only the combination of epidural puncture needle and spinal puncture needle can be used to achieve spinal cord cell transplantation. In this method, the epidural puncture needle is punctured into the spinal canal, and under the guidance of the epidural puncture needle, the spinal anesthesia puncture needle is inserted below the dura mater, and then the cell suspension is injected with an ordinary syringe. Although this method can be applied clinically, there are the following problems. One is that the epidural puncture needle is relatively t...

AI Technical Summary

Problems solved by technology

Although this method can be applied clinically, there are the following problems. One is that the epidural puncture needle is relatively thick and the trauma is large. Omissions cause waste of cell resources and affect the clinical treatment effect; second, there is no scale on the epidural puncture needle, and the depth of needle insertion cannot be seen, which leads to large operational errors and blindness, which affects the accuracy of the cell transplantation site; Because the needle of the epidural puncture needle is a straight bevel, the lumbar anesthesia puncture needle can only be extended vertically, and can only be aimed at one point at a time after being extended. For example, multiple punctures are required for multi-point transplantation, which is very troublesome, time-consuming and labor-intensive. , causing many times of pain to the patient; Fourth, there is no special matching injector and sampler, and only ordinary syringes can be used, and the measurement of ordinary syringes is at the milliliter level, which does not meet the micro-upgraded cell injection standards
