Description

Auxiliary suite for lateral lumbar puncture

Technical Field

The utility model relates to a puncture auxiliary suit, in particular to a lateral lumbar puncture auxiliary suit.

Background

In diagnosis and treatment and teaching of various hospitals, especially neurology department and anesthesia department, the independent completion of lumbar puncture is a skill that each clinician must possess. Lumbar puncture can help diagnose central system infectious diseases such as meningoepithymitis, demyelinating diseases such as Ji Lanba Rate syndrome and peripheral neuropathy, and can also perform intraspinal treatment or intraspinal anesthesia after smoothly extracting cerebrospinal fluid in lumbar puncture operation.

However, studies have shown that clinical operators have only 46% success rate in lumbar puncture surgery. The basic procedure for lumbar puncture is to include the following seven points: positioning the puncture point, sterilizing, spreading towel, locally infiltrating and anesthetizing layer by layer, placing the lumbar puncture needle into the subarachnoid space, measuring the pressure of cerebrospinal fluid outflow, collecting the cerebrospinal fluid, and pulling out the puncture needle sterilizing and covering dressing. In the operation process, the lumbar puncture needle is used as a main tool and plays an important role in determining whether the operation is successful or not.

The lumbar puncture needle widely used in clinic has a simpler structure and comprises a hollow needle body, a needle core and a needle seat, wherein the needle core is nested in the needle body, and the tail end of the needle core is fixed with the needle seat. Such equipment is convenient for experienced doctors, but is not too crude for young doctors or novice doctors who have not performed lumbar puncture, and there are some areas to be improved. For example, the positioning point before lumbar puncture and the two points of inserting and puncturing the subarachnoid space with the lumbar puncture needle are extremely experienced. Many old or obese patients have unobvious lumbar vertebra gaps or serious lumbar vertebra hyperosteogeny, so that positioning points are unclear, and even if the positions of adjacent cone bones are clear under ultrasonic guidance, the direct puncture method can not avoid puncture failure caused by collision with bones. Research shows that the side-entering method (namely, puncturing by 1.5cm beside a direct puncturing positioning point and forming 75 degrees with the skin) has higher puncturing success rate than the direct-entering method, and the reason is probably that the side-entering method can effectively avoid the hyperplastic bone, and the falling feeling is obvious when puncturing the ligament and puncturing the subarachnoid space. However, the existing lumbar puncture needle has no auxiliary positioning mark, and the isolated needle body easily slides along with skin and subcutaneous tissue during puncture, so that a positioning point is deviated in the puncture process, and puncture failure is caused. In addition, even if the puncture is successful, the needle core is easily polluted and the cerebrospinal fluid is easily wasted when the needle core is taken out of the hollow needle body. When the cerebrospinal fluid is subjected to pressure measurement, a cerebrospinal fluid pressure measuring glass tube which is at a right angle of 90 degrees is spliced and aligned with the needle opening to measure the pressure, and the operation is superfluous in some patients without obvious signs of increased intracranial pressure, and is dangerous in patients with obvious signs of increased intracranial pressure. Because can roughly judge whether its pressure is greater than 1.76kpa (normal range is 0.78-1.76 kpa) according to the cerebrospinal fluid drip number, and if patient's cerebrospinal fluid pressure is too high, the operator needs the fixed needle body of one hand, and the glass tube pressure measurement of hand fixed connection is not steady yet, and in this process not only is very inconvenient, still leads to the dropping pollution of glass tube easily.
