In order to avoid affecting the safety and progress of the operation, ensure the cleanliness and sterility of the operation area, and enable the operation to proceed smoothly, a surgical hand fixing guard is used to fix and limit the hands.

[0003] The prior art disclosed in Patent No. CN220632482U provides a surgical bed guard. According to the thickness of the patient, the shape of the guard is adjusted to better place the patient's hands and avoid the patient's hands from sliding off the handrail, thereby affecting the performance of the surgical operation. Meanwhile, the inner and outer binding belts are arranged to cooperate with the shape of the guard to adopt different binding modes to more stably fix the patient's hands on the handrail, so that the surgical operation is less affected by the patient's hands, and the risk of occurrence during the operation is reduced. However, the surgical bed guard in the above-mentioned related technology still has the following defects: when the hands are fixed and limited in the prior art, the binding form is difficult to release quickly in the predetermined emergency, which has certain safety hazards. Therefore, the application provides a surgical hand fixing guard facilitating emergency release. CONTENT OF THE INVENTION
