Description

Technical Field

[0001] The invention belongs to the technical field of gypsum removal, and in particular relates to a gypsum removal device. Background Art

[0002] Modern medicine has developed rapidly. Orthopedic diseases that were previously incurable can now be basically treated through certain surgical resections or implants. Ordinary fractures can be cured by fixation and recuperation after bone setting. Plaster fixation is the most common fixation method. At present, when doctors use plaster saws to remove plaster from patients, there is no tool to fix the arm, which causes the arm to swing during the removal process, which is easy to cause secondary injuries. The saw teeth of existing electric plaster saws are mostly exposed to the outside, which is easy to scratch doctors or patients during use, causing secondary injuries to patients. Another method is to soak the plaster with warm water and then remove the plaster. This method does not bring danger to patients, but it takes a long time and the removal is slow. In the prior art, a Chinese patent with publication number CN115737289B discloses a shock-absorbing orthopedic plaster crushing and removal device. The prior art fixes the patient's limbs by two arc-shaped limiting plates, but the diameters of the patient's limbs at different positions are different, and the patient's limbs cannot be fixed in a close fit.
