A fixation device for children's lumbar puncture

Abstract

The invention discloses a fixing device for children's lumbar puncture, and mainly relates to the technical field of pediatric lumbar puncture. Including the support frame, two fixed tables are symmetrically fixed on the support frame, and an auxiliary table coplanar with the top surface is arranged between the two fixed tables. There is a mounting slot between them, and a grip bar that slides along its length is provided in the operating slot, and a bar-shaped hole connecting the two is provided between the operating slot and the installing slot, and a bar-shaped hole is provided in the bar-shaped hole that slides and fits with it. Sliding plate, a connecting rod is arranged between the two sliding plates, and a wheel frame is provided at the front and rear ends of the groove bottom of the installation groove. The wheel frame is rotated and matched with a pulley driven by electricity, and the pulley is wound with a belt drive. The transmission belt, the bottom surface of the connecting rod is fixed on the top surface of the transmission belt on the upper side. The beneficial effect of the invention is that it reduces the work intensity of the assistant, and more importantly, ensures the safe control of the child's body posture during the operation.

Description

technical field [0001] The invention relates to the technical field of pediatric lumbar puncture, in particular to a fixing device for children's lumbar puncture. Background technique [0002] Lumbar puncture is a commonly used clinical operation. It can be used to diagnose various inflammatory diseases of the central nervous system, vascular diseases, spinal cord lesions, suspected intracranial space-occupying lesions, undiagnosed nervous system diseases, pneumocephalus, myelinography, etc.; also used for cerebrospinal fluid pressure High drainage (decompression) and infusion of drugs to treat central nervous system disorders. [0003] The method of operation is that the patient lies on the side on the bed with his hands on his knees, so that the lumbar spine is kyphosis and the intervertebral space is widened. Local routine disinfection, infiltration anesthesia, puncture. Generally, there is resistance after puncturing 4 to 5 cm, and the resistance suddenly decreases. A...

Problems solved by technology

[0009] In the case of poor hole distance and self-control, children often have reverse force and struggle. In order to ensure the safety of the operation, the assistant hugs the child with great effort throughout the whole process. Not only is it laborious, but the strength of the upper limbs is limited. The internal restraint is relatively out of force. Nowadays, the development of children is relatively good, and children can grow to 1.2m. The safety of bare-handed restraint is the primary difficulty.

At the same time, as the operation progresses, continuous force will also cause upper limb fatigue and loss of restraint ability

Therefore, relying only on the assistant's bare-handed restraint, there are still great risks and hidden dangers for children's lumbar puncture surgery.
