Abstract

The invention relates to a magnetic resonance clinical patient head assisted fixation device and an operation method thereof. The device comprises a fixing plate, an adjusting rod, a limiting block, asupporting spring, a limiting rod, a positioning sleeve and a sliding rod, the lower side of the fixing plate has an adjusting rod groove, the adjusting rod groove is adapted to the adjusting rod, the adjusting rod is connected to the adjusting rod groove, the adjusting rod slides in the adjusting rod groove, the upper side of the adjusting rod groove and the upper side of the adjusting rod are connected by a tooth groove, the lower part of the adjusting rod groove has a limiting block groove, the limiting block groove is adapted to the limiting block, the limiting block is connected to the limiting block groove, the limiting block slides in the limiting block groove, and the upper surface of the limiting block is connected with the adjusting rod, and the limiting block is internally connected with the upper end of a supporting spring. The lower end of the support spring is connected to the fixing plate, the outer side of the fixing plate has a limiting protrusion, and the limiting protrusion is internally screwed to the limiting rod, and the inner end of the limiting rod is stuck on the limiting block.

Description

technical field [0001] The invention relates to the field of fixation frames, in particular to an auxiliary head fixation device and an operation method for clinical magnetic resonance patients. Background technique [0002] When a patient is undergoing a head MRI clinical examination, the patient's head is required not to move, which affects the accuracy of the examination results on the one hand. However, the existing auxiliary head fixation frame for clinical magnetic resonance patients is inconvenient to adjust, so that the fixation frame cannot be adjusted according to the head circumference of the viewer. Contents of the invention [0003] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a convenient and adjustable auxiliary head fixation device and operation method for clinical magnetic resonance patients. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] An au...
