Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary equipment, in particular to an operating room pillow with adjustable height. Background Art

[0002] When performing neck surgeries such as thyroid, external jugular vein puncture, supraclavicular and inferior vein puncture, and cervical plexus anesthesia, especially thyroid surgery, the patient's shoulders need to be raised and the head tilted back, so that the chin, trachea, and sternum are at the same level as much as possible, so as to fully reveal the surgical field of view and facilitate surgical operations. Neck surgery is not only cumbersome to operate, but also takes a long time. Patients need to maintain this posture for a long time (shoulders raised, head tilted back, chin, trachea, and sternum at the same level), which will bring various discomforts to patients, including difficulty in maintaining position during surgery, shortness of breath, dyspnea, and even irritability, which affects surgical operations and fails to achieve the expected surgical results; symptoms such as head and neck pain, nausea, and vomiting occur after surgery, causing patients to be mentally fatigued and difficult to fall asleep, which increases the psychological burden on patients.

[0003] Existing surgical pillows are usually made of materials such as gel and polyurethane foam sponge as fillings. This type of pillow is mainly composed of a surface layer and a filling material, and has a relatively simple structure. It is unable to adjust the specific shape of the patient's head and neck according to the needs of the operation, resulting in some patients' heads or necks being suspended in the air during the operation, increasing the risk of damage to the cervical spine and nerves; and due to the diversity of surgical steps, existing surgical pillows cannot adjust the height of the head according to actual needs, which brings inconvenience to the surgical operation; in addition, if the surgical pillow does not provide sufficient support for the head and neck, it will make the patient feel uncomfortable, which not only affects the patient's surgical experience, but may also affect the smooth progress of the operation. Summary of the invention

[0004] The present invention intends to provide an operating room pillow with adjustable height, which is provided with a shoulder pillow, a head pillow and a neck pillow, so as to support the patient's shoulders, neck and head during surgery.

[0015] The principle and beneficial effects of the technical solution are: 1. The invention provides an operating room pillow with adjustable height. The lower end surface of the base and the lower end surface of the fixed pillow are arranged at the same horizontal plane, which is convenient for patients to use. The base is connected with a height adjustment component, and the shoulder and back pillow are connected with a connecting plate and a head pillow. The patient's back and shoulders are placed on the shoulder and back pillow, and the head is placed on the head pillow. The connecting plate is connected with the telescopic end of the height adjustment component. By controlling the height of the height adjustment component, the height of the entire operating room pillow (shoulder and back pillow, head pillow) can be adjusted to meet the height requirements of patients of different body shapes, different surgeries or different stages of surgeries, which is convenient for surgical operations. The height adjustment component is composed of the following: The height adjustment assembly comprises a fixed block, two first linkage arms, a linkage block, a lead screw, an adjustment handle, two second linkage arms and an upper fixed block. When the adjustment handle is rotated, the adjustment handle drives the lead screw to rotate. The rotation of the lead screw causes the two linkage blocks to move toward each other along their axial directions under the action of the thread. The horizontal movement of the linkage block drives the first linkage arm and the second linkage arm connected thereto to rotate. The free ends of the first linkage arm and the second linkage arm are rotationally connected to the lower fixed block and the upper fixed block respectively. The lower fixed block is fixedly connected to the base, and the upper fixed block is fixedly connected to the connecting plate. That is, the height adjustment assembly constitutes a "scissor jack" to adjust and support the connecting plate to achieve the adjustment of the pillow height. 2. The invention provides an operating room pillow with adjustable height, wherein the head pillow and the shoulder pillow are rotatably connected, and the two are also connected by a support assembly, and the relative angle between the head pillow and the shoulder pillow is changed by adjusting the length of the support assembly, so as to meet the needs of different surgeries or different stages of surgeries for the angle between the head and the shoulder, and facilitate surgical operations; wherein the support assembly is composed of a lower threaded rod, a threaded sleeve and an upper threaded rod, and the lower threaded rod and the upper threaded rod are connected to the two ends of the threaded sleeve by threads with opposite rotation directions, and the lower threaded rod and the upper threaded rod are rotatably connected to the connecting plate and the head pillow by a connecting sleeve, and the rotation When the threaded sleeve is moved, the lower threaded rod and the upper threaded rod move toward each other along the axial direction of the threaded sleeve to adjust the overall length of the support assembly; the connection relationship among the shoulder pillow, the head pillow and the support assembly is as follows: the head pillow is at a certain distance from the rotation connection of the shoulder pillow, the head pillow is at a certain distance from the rotation connection of the upper threaded rod, and the rotation connection of the head pillow with the shoulder pillow and the rotation connection of the lower threaded rod is at a certain distance, that is, the connection of the three angles of the triangle is rotationally connected, two of which are fixed, and when the other side changes, the three internal angles of the triangle will also change, so as to adjust the angle between the head pillow and the shoulder pillow; 3. The height-adjustable operating room pillow provided by the present invention has a placement groove on the upper surface of the head pillow, and a support rod is connected to the placement groove through a damping shaft. During surgery, the support rod is used to support the drape covering the patient's face, so as to facilitate the patient's breathing and improve the patient's comfort during surgery; a groove is provided on the head pillow for placing the head, so as to facilitate the positioning of the patient's head during surgery; two placement grooves are provided on the head pillow at the front and rear sides of the groove, and four support rods are provided.
