AI Technical Summary
When the patient with posterior fossa tumor was in a flat position after surgery, the occipital wound was compressed and the head and neck could not maintain a straight line, resulting in poor venous return and increased intracranial pressure.
A special postoperative pillow including a base, a double-headed motor, a sliding pillow and a lifting device was designed. The threaded rod and a sliding rod are driven by the motor to move the sliding pillow backward, adjust the head support position, and use semi-elliptical slots and elliptical The head support achieves adaptive fixation of the head, avoiding wound compression and straight maintenance of the head and neck.
It effectively avoids wound compression, promotes venous return, reduces intracranial pressure, and helps patients recover.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of special pillows for surgery, in particular to a special pillow for patients with posterior cranial fossa tumors after surgery. Background Art
[0002] Patients with posterior cranial fossa tumors adopt the supine position (without pillow) after surgery. The wound on the occipital region (behind the ear) is under pressure, and in order to protect the wound from pressure, the patient cannot keep the head and neck in a straight line (venous return is poor, leading to increased intracranial pressure).
[0003] Therefore, the utility model provides a special pillow for patients with posterior cranial fossa tumors after surgery to solve the above problems. Utility Model Content
[0004] The utility model aims to provide a special pillow for patients with posterior cranial fossa tumors after surgery, so as to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special pillow for patients with posterior cranial fossa tumors after surgery, characterized in that it comprises a base and two left and right sliding pillows, a double-headed motor is provided on the top of the base, and the two rotating shafts of the double-headed motor are fixedly connected to threaded rods, and the ends of the two threaded rods are rotatably mounted on the inner walls of the left and right baffles on the top of the base, a sliding rod parallel to the threaded rod is provided above the base, and the two ends of the sliding rod are fixedly mounted on the inner walls of the left and right baffles on the top of the base, respectively, the sliding pillow is threadedly engaged with the threaded rod, and the sliding pillow is slidably mounted on the sliding rod, a lifting device is provided at the center of the top of the base, and a head support is fixedly mounted on the top of the lifting device.
[0006] Preferably, a power supply is provided on the top of the base, and a controller is embedded and installed on the outer wall of the left baffle on the top of the base. The controller is electrically connected to the double-headed motor, the lifting device, and the power supply respectively. The power supply is a rechargeable lead-acid battery, which can power the double-headed motor, the lifting device, and the controller.
[0007] Preferably, the portions of the left and right sliding pillows that are close to each other are provided with semi-elliptical slots, and the headrest is an elliptical structure and can be engaged with an elliptical groove formed by the two slots.
[0008] Preferably, the surface of the sliding pillow is paved with a latex pad, and the top surface of the sliding pillow is a wavy curve.
[0009] Beneficial effects of the utility model:
[0010] When the patient undergoes surgery for a posterior cranial fossa tumor, the medical staff controls the double-headed motor and the lifting device respectively through the controller. The rotation of the two rotating shafts of the double-headed motor drives the threaded rod to rotate, which in turn makes the left and right sliding pillows move dorsally. The dorsal movement distance of the two sliding pillows is adjusted according to the size of the patient's head. At the same time, the lifting device is adjusted to lower the head support to reserve space for the patient's posterior skull. The semi-elliptical grooves on the left and right sliding pillows can be used to lock and limit the head, which can not only avoid pressure on the wound, but also prevent the head and neck from keeping in a straight line, resulting in poor venous return and increased intracranial pressure.

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0018] The utility model provides Figure 1-4The pillow shown is a special pillow for patients with posterior cranial fossa tumors after surgery, comprising a base 1 and two left and right sliding pillows 2. A double-headed motor 3 is provided on the top of the base 1. The two rotating shafts of the double-headed motor 3 are fixedly connected to threaded rods 4. The ends of the two threaded rods 4 are rotatably mounted on the inner walls of the left and right baffles on the top of the base 1 respectively. A sliding rod 5 parallel to the threaded rod 4 is provided above the base 1. The two ends of the sliding rod 5 are fixedly mounted on the inner walls of the left and right baffles on the top of the base 1 respectively. The sliding pillow 2 is threadedly engaged with the threaded rod 4. The sliding pillow 2 is slidably mounted on the sliding rod 5. A lifting device 6 is provided at the center position of the top of the base 1, and a head support 9 is fixedly mounted on the top of the lifting device 6.
[0019] Furthermore, a power supply 7 is provided on the top of the base 1, and a controller 10 is embedded and installed on the outer wall of the left baffle on the top of the base 1. The controller 10 is electrically connected to the double-headed motor 3, the lifting device 6, and the power supply 7 respectively. The power supply 7 is a rechargeable lead-acid battery, which can supply power to the double-headed motor 3, the lifting device 6, and the controller 10.
[0020] Furthermore, a semi-elliptical slot 8 is provided at the mutually adjacent portions of the left and right sliding pillows 2 , and the headrest 9 is an elliptical structure and can be engaged with an elliptical groove formed by the two slots 8 .
