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

Embodiment Construction

[0010] With reference to the accompanying drawings, the lumbar puncture positioner of the present invention will be described in detail below with this embodiment, but it is not intended to limit the present invention.

[0011] In the embodiment, the lumbar puncture positioner is composed of a base, a fixing belt, a positioning plate and a laser tube on it, a gravity sensor, a control circuit, and a loudspeaker.

[0012] When in use, the patient lies on his side on a hard board bed, the horizontal axis of the body is perpendicular to the bed plane, the waist and abdomen are exposed, the puncture point is selected, a straight line is drawn from the puncture point along the spinous process of the lumbar vertebrae, disinfected with povidone iodine, and a sterile drape is laid on the Place the positioner at an appropriate distance above the puncture point. The plane of the positioning plate is just on the spinous process line. Fix the positioner with a fixed belt. Turn on the power...

Abstract

A lumbar puncture positioner is composed of a base, a positioning plate, a flexible belt and a fixing belt. A laser tube, a gravity sensor, a control circuit and a loudspeaker are arranged on the positioning plate. During use, the positioner is fixed to the proper distance above a puncture point, a power source is powered on, a position adjusting knob is adjusted to enable the positioning plate tobe horizontal, it is ensured that a laser beam and the spine line coincide, and an operator feeds a lumbar spinal needle from the puncture point along the laser beam until puncture succeeds. The advantages of being high in locating precision, low in cost and easy to popularize are achieved.

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 ...
