Auxiliary device for adjusting head positions in head and neck surgery

Abstract

The invention provides an auxiliary device for adjusting head positions in head and neck surgery. The auxiliary device comprises a base. A groove is formed in one end of the base. A neck support is arranged in the groove. A rotating shaft penetrates through the center of the neck support. A head rack is arranged at the outer side of the neck support. A connecting block is arranged at the bottom of the head rack. A connecting shaft is arranged on the connecting block. One end of the connecting shaft is connected with the connecting block, and the other end of the connecting shaft is connected with the neck support. The auxiliary device is further provided with a control system. The control system comprises positive and negative pole change-over switches, a speed adjusting button, a first motor, a second motor, a speed adjusting chip and a transformation speed changer. An output shaft of the first motor is connected with the connecting shaft. An output shaft of the second motor is connected with the rotating shaft. The positive and negative pole change-over switches comprise a first positive and negative pole change-over switch and a second positive and negative pole change-over switch. The first motor is connected with the speed adjusting chip through the first positive and negative pole change-over switch. The second motor is connected with the speed adjusting chip through the second positive and negative pole change-over switch. The speed adjusting button and the transformation speed changer are connected with the speed adjusting chip. A power line is led out of the transformation speed changer. By means of the auxiliary device, the upper, lower, left and right positions of the head of a patient can be adjusted.

Description

technical field [0001] The invention relates to an auxiliary device for head position adjustment in head and neck surgery. Background technique [0002] Surgery for head and neck tumors often includes steps such as tumor removal, neck lymph node dissection, and surgical cavity sealing. During the implementation of these steps, the patient's head needs to be in different positions. The tumor removal process usually requires leaning back or turning the head to the healthy side according to the location of the tumor. In the process of neck lymph node dissection, it is necessary to expose the relevant structures on the side of the neck as much as possible, so the head needs to be turned to the opposite side. When the operation cavity is closed, in order to reduce the suture tension, it may be necessary to return the head to the normal or forward position. [0003] It can be seen that during tumor surgery, it is often necessary to change the tilt angle and direction of the head...

AI Technical Summary

Problems solved by technology

However, there is currently a lack of auxiliary devices for head and neck surgery in multiple directions or an operating table with corresponding functions. Most surgeons manually change the head position during the operation, and there are the following problems: 1. Changes in the position of the head during surgery The required strength and speed cannot be mastered, causing postoperative discomfort or complications; 2. The changed head position cannot reach the best angle, so that the surgical cavity or tissue structure is not exposed enough, which affects the surgical operation; 3. Changes During the head position, it is necessary to move the surgical sterile drape, which leads to contamination of the surgical field; 4. Some positions require the doctor to keep the head with his hands to maintain the position and angle of the head, which consumes the doctor's physical strength and affects the accuracy of the operation
