A lumbar puncture fixation device

Abstract

The present invention relates to the technical field of medical equipment, in particular to a lumbar puncture fixation device, comprising a main body, one side of the main body is provided with a chute, the inside of the chute is provided with a slide plate, and the top end of the slide plate is provided with an adjustment mechanism , the top end of the slide plate is located on one side of the adjustment mechanism, and an adjustment seat is provided, and one side of the adjustment mechanism is connected with an extruding mechanism. The beneficial effect is that: through the fixed block, the elastic bar and the bracket, according to the curved structure of the fixed block, the device can fit the patient's curled up posture, and the elastic bar can be moved to both sides after the pulley is in contact with the patient. Expansion, not only has a certain buffer, but also can exert pressure on the patient's back in the horizontal direction. At the same time, the two sets of brackets that are rotatably connected to the elastic bar will also expand to both ends after contacting the patient, and then in the longitudinal direction. Put pressure on the back of the patient, and the combination of the two can effectively improve the stability of the puncture operation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a lumbar puncture fixing device. Background technique [0002] Lumbar puncture is one of the most commonly used examination methods in neurology and surgery. It can be used for both diagnosis and treatment. Lumbar puncture can be used to understand the nature of cerebrospinal fluid and assist in the diagnosis of central nervous system inflammation or hemorrhagic diseases; measure cerebrospinal fluid pressure to understand The level of intracranial pressure and the patency of the subarachnoid space; for patients with intracranial (or spinal cord) subarachnoid hemorrhage, inflammation or surgery. [0003] At present, the operation method of lumbar puncture is: the patient lies on his side on a hard board bed, his back is perpendicular to the bedside, his head is bent toward his chest, his waist is arched backward, and his knees are bent toward his abdomen. The skin at th...

Problems solved by technology

[0003] At present, the operation method of lumbar puncture is: the patient lies on his side on a hard board bed, his back is perpendicular to the bedside, his head is bent toward his chest, his waist is arched backward, and his knees are bent toward his abdomen. The skin at the puncture point is fixed with the left hand, the needle is held in the right hand, and the needle is inserted from the interspinous space perpendicular to the spine. However, the disadvantage of this method is that the operation process is performed manually by medical personnel. Fatigue, and most of the existing lumbar puncture fixation devices are fixed in structure, which cannot be applied to different groups of people, and the caliber of the needle tube is also strictly limited
