Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a skull puncture positioning ruler. Background Art

[0002] Puncture is a diagnostic and treatment technique, which refers to inserting a puncture needle into the body cavity to extract secretions for testing, or injecting gas or contrast agent into the body cavity for angiography, or injecting drugs into the body cavity. Skull puncture is a common puncture treatment method. According to the location of the intracranial hematoma shown on the CT scan, the skull is marked and then the puncture operation is performed. The traditional positioning method relies on the doctor's manual positioning, which has a large deviation. Subsequently, instruments for auxiliary positioning have been developed, such as brain stereotaxic instruments, stereotaxic rulers and other equipment.

[0003] In the related art, reference can be made to the Chinese invention patent application with application number CN202310142040.9, which discloses a cranial stereotactic positioning ruler, including a supporting part, and a positioning adjustment mechanism, a first positioning mechanism and a second positioning mechanism are respectively provided on two opposite sides of the supporting part, the supporting part includes a head pad base, and vertically arranged limit pins are fixedly connected on both sides of the head pad base, and the limit pins are vertically slidably connected in the limit grooves, and the limit grooves are arranged at the bottom end of the head pad, and a lifting and fixing bracket and a lifting rack track are fixedly connected in the head pad base, and a lifting rod is horizontally rotatably connected to the lifting and fixing bracket, and the lifting rod extends into the lifting rack track and is coaxially fixed with a gear, and the gear is meshed with a lifting rack, and the lifting rack is vertically slidably connected in the lifting rack track, and the top end of the lifting rack extends out of the lifting rack track and is connected to the bottom end of the head pad, and the end of the lifting rod away from the lifting rack track is transmitted out of the head pad base and is fixed with a lifting nut.

[0004] The lifting nut drives the lifting rod to rotate in the horizontal direction, and the lifting rod drives the lifting rack in the lifting rack track to slide up and down through the gear, thereby driving the head pad to rise and fall. The limit pins make the head pad only slide in the vertical direction to adapt to patients with different head shapes. The puncture point is positioned through the positioning adjustment mechanism, the first positioning mechanism and the second positioning mechanism. However, this device is complicated to operate and requires multiple adjustments for different patients, which reduces the convenience of skull puncture positioning. Utility Model Content
