Auxiliary propelling device for lumbar puncture needle

Abstract

The invention belongs to the field of medical instruments, and particularly relates to an auxiliary propelling device for a lumbar puncture needle. This auxiliary propelling device for a lumbar puncture needle comprises a pressure detection accessory detachably connected with the lumbar puncture needle; and an auxiliary propeller which is detachably connected with the pressure detection accessory and is in communication connection with the pressure detection accessory. In the application, the power is provided for the puncture needle through the propelling device, so that the puncture needle can easily penetrate through the skin and hyperplasia sclerotin, and the situation that when the puncture needle enters, the needle tip is tilted or medical staff cannot apply force to puncture is avoided. According to the pressure detection accessory, pressure can be detected in real time, useless loss of cerebrospinal fluid can be reduced, and the influence on human health during puncture is reduced to the maximum extent.

Description

technical field [0001] The invention belongs to the field of medical appliances, and in particular relates to an auxiliary propulsion device for lumbar puncture needles. Background technique [0002] Cerebrospinal fluid pressure measurement and cerebrospinal fluid sample sampling are commonly used diagnosis and treatment methods in the clinical diagnosis of neurology. At present, the commonly used method of cerebrospinal fluid sampling is pressure measurement or sampling with puncture needle and sterile catheter. However, in actual operation, during the puncture process, medical personnel manually puncture the puncture needle into the patient's spinal suture, but because the puncture needle is relatively thin, the hardness is low. When the medical personnel puncture, some patients' skin The toughness is relatively high, and the puncture needle may bend outside the skin. Some patients have the problem of lumbar disc herniation or bone hyperplasia, so even if the puncture is ...

Problems solved by technology

However, in actual operation, during the puncture process, medical personnel manually puncture the puncture needle into the patient's spinal suture, but because the puncture needle is relatively thin, the hardness is low. When the medical personnel puncture, some patients' skin The toughness is relatively high, and the puncture needle may bend outside the skin

Some patients have the problem of lumbar disc herniation or bone hyperplasia, so even if the puncture is successful, the puncture needle is still difficult to penetrate due to the small spine suture or the obstruction of bone, and the needle may even break.
