Description

Head fixation device for fiberoptic bronchoscope operation

Technical Field

The utility model relates to the technical field of intraoperative auxiliary equipment, in particular to a head fixing device used for fiberbronchoscope operation.

Background Art

The use of fiberoptic bronchoscopy in the emergency department includes: inserting into the trachea and bronchi through the nose, oral cavity and throat to directly observe the lesions therein, which is an important means and technology for the diagnosis and treatment of respiratory diseases. In the fiberoptic bronchoscopy room, most patients lie flat on the transfer bed of the emergency department. In order to relieve the patient's nervousness and suppress the patient's laryngeal reflex, cough reflex, nausea and vomiting and other symptoms, sedatives and drugs that inhibit respiratory secretions are used before surgery for patients who meet the conditions. For such patients, since they have no autonomous consciousness during the operation, the doctor will have difficulty controlling the direction of the fiberoptic bronchoscopy during the fiberoptic bronchoscopy due to the tilt of the head, which will increase the difficulty of the operation.

Since the commonly used emergency department transfer beds do not have a special patient head fixation device, in order to solve the problem of patient head tilt during surgery, the current method used is for the doctor to hold the bronchoscope or the patient's head from the side, which causes certain interference to the doctor who mainly operates the bronchoscope.

Regarding the problem of fixing the patient's head during bronchoscopic operation, the applicant has learned that the prior art has a solution to the problem of fixing the patient's head from the perspective of bed design. This solution uses a special bed and also uses auxiliary devices to fix the patient's head on the basis of an ordinary bed, such as the head fixation device provided in patent application No. CN202021598610.3.

In view of the fact that patients are sedated during bronchoscopic surgery, a head fixation device suitable for ordinary emergency department transfer beds, with a simple structure and easy use, is provided, which is beneficial to the smooth implementation of bronchoscopic surgery.
