A lumbar puncture locator

Abstract

A locator for lumbar puncture needles is composed of a base, a positioning plate, a soft belt, and a fixing belt. The positioning plate is equipped with a laser tube, a gravity sensor, a control circuit, and a loudspeaker. When in use, fix the locator at an appropriate distance above the puncture point, turn on the power, adjust the position adjustment knob to make the positioning plate horizontal, and ensure that the laser beam coincides with the spinous process line. The needle is inserted from the face until the puncture is successful; it has the advantages of high positioning accuracy, low cost, and easy promotion.

Description

technical field [0001] The invention relates to a locator for lumbar puncture needles, which belongs to the field of medical equipment, in particular to an auxiliary locator for improving the success rate of lumbar puncture. Background technique [0002] At present, lumbar puncture is widely used in neurology, infectious diseases, emergency departments and other clinical departments, and is one of the main operations for the diagnosis and treatment of intracranial diseases. The main point of this operation is that the patient is lying on his side, and the transverse axis of the body is perpendicular to the horizontal plane. The surgeon locates the 3rd and 4th intervertebral space of the lumbar spine (in most cases) as the puncture point through the body surface. Insert the needle parallel to the horizontal plane until it enters the lumbar subarachnoid space, measure the pressure of the cerebrospinal fluid, collect the cerebrospinal fluid, and collect the cerebrospinal fluid ...

Problems solved by technology

However, due to the non-standard position of the patient and the error of the operator's visual inspection, the success rate of puncture is not very high. It is especially difficult for obese patients and patients with lumbar diseases, which brings great pain to the patient, and often affects the diagnosis and treatment due to puncture failure.

[0003] In order to improve the success rate of puncture, many lumbar puncture positioners have emerged as the times require. Some of the principles are to leave a puncture hole on the base, and the lumbar puncture needle enters from here. The direction of the needle is changed, and the practicability is low; some people make a special lumbar puncture bed, fix the patient on the bed, and make the patient reach a suitable position through the rotation of the bed. This method is cumbersome and expensive, and cannot be directly applied on the hospital bed. It is also very low; some patients meet the puncture requirements through complex mechanical fixation devices, the application method is cumbersome, and the clinical value is low.
