The invention provides a fixation device for bronchoscopy and surgeries. The fixation device comprises a lying plate, a head fixation device, a chest fixation device, an upper limb fixation device and a lower limb fixation device, wherein the head fixation device, the chest fixation device, the upper limb fixation device and the lower limb fixation device are successively arranged on the lying plate, the head fixation device, the chest fixation device, the upper limb fixation device and the lower limb fixation device respectively correspond to the head, the chest, the upper limbs and the lower limbs of the human body. The fixation device for the bronchoscopy and the surgeries has the advantages that by the construction of a protective device for fixation of patient's body in the bronchoscopy and the surgeries, the neck is in a medical treatment function position and the activity of the body is reduced by reasonable fixation on the head of the patient, and physical treatments of the chest is increased. The risks of patient examination and operation are reduced, the number of medical staff is reduced, the operability of the examination and operation is increased, and the occurrence of the complications is reduced.
