Adjustable headrest for patient after oral and maxillofacial region tumor excision flap repair operation

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an adjustable headrest for an oral and maxillofacial region tumor resection flap repair postoperative patient, the adjustable headrest comprises a headrest body and a base, the base is fixedly connected with an adjusting and controlling seat, the adjusting and controlling seat is fixedly connected with a support frame, the headrest body is rotatably arranged on the support frame, and the headrest body is rotatably arranged on the support frame. And two lead screws are rotationally connected between the base and the adjusting and controlling seat, L-shaped supporting rods are connected to the two lead screws in a threaded mode, and a guide sliding rail is fixedly arranged on the lower side of the headrest body. The angle of the headrest can be adjusted according to needs, the complexity of manual supporting is avoided, the placement stability of the head of a patient and the accuracy of the placement angle can be guaranteed, in addition, the distance between the neck supporting pad and the headrest can be adjusted so that the device can adapt to patients with different neck lengths, the heat dissipation mechanism is additionally arranged, and the heat dissipation effect is good. And automatic heat dissipation can be conducted on the lead screw component in cooperation with the angle regulation and control process, so that the service life of the lead screw component is prolonged.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an adjustable headrest for patients after oral and maxillofacial tumor resection skin flap repair. Background technique [0002] Oral and maxillofacial tumors are relatively common in clinical practice. Epidemiological statistics show that oral and maxillofacial tumors account for 8% to 10% of systemic tumors, of which the incidence of malignant tumors is (1 to 4) per 100,000, accounting for 1% of systemic malignant tumors. 2% to 6%. Surgical resection of primary lesions and neck dissection is an important method for clinical treatment of oral and maxillofacial malignancies at this stage. Due to extensive oral and maxillofacial defects after surgery, free tissue flaps need to be reconstructed and repaired. During the repair process, a headrest is often used to provide support for the patient's head, and at the same time, the patient's head is raised to facilitate the repa...

Problems solved by technology

[0003] In the process of repair, it is often necessary to deflect the patient's head left and right. In order to match the deflection of the patient's head and give the patient a comfortable support, the headrest often needs to adjust a certain angle with the left and right, but the traditional headrest generally The angle cannot be adjusted, and it is often necessary for medical staff to temporarily find cushions to raise one side of the headrest, so that the headrest can be tilted to a certain angle to achieve the required angle. Effective fixation makes it often necessary to manually support the patient's head during postoperative repair, which is time-consuming and laborious
