[0002] When performing surgery on the shoulder, femur, clavicle and other parts, in order to ensure a sterile environment in the surgical area, doctors usually use sterile sheets to cover the patient's skin. However, this covering method often brings some inconveniences and risks in actual operation. First, external forces such as sterile sheets or the surgeon's arm may inadvertently compress the patient's endotracheal tube or laryngeal mask. This compression may cause the patient to experience discomfort symptoms such as sore throat and hoarseness after surgery. Secondly, for patients undergoing general anesthesia, due to the obstruction of sterile sheets, it is difficult for doctors to directly observe the patient's breathing circuit during the operation, which undoubtedly increases the risk of the operation. Therefore, how to improve this covering method to ensure the smooth progress of the operation while reducing the patient's postoperative discomfort and surgical risks is an issue that needs to be focused on and solved in the current medical field.

[0033] An embodiment of the present application provides an adjustable supporting head frame for supporting sterile cloth for patients during surgery, so that a certain distance is maintained between the patient's face and the sterile cloth. This can prevent the patient's endotracheal tube or laryngeal mask from being compressed by the sterile cloth, thereby reducing the patient's discomfort. It can also provide doctors with the convenience of observing the surgical field and reducing surgical risks.

[0034] like Figure 1 As shown, the adjustable support head frame includes a support rod 100 and a first support component.

[0035] The two ends of the support rod 100 are respectively a first end 120 and a second end 130, and the first direction is parallel to the axial direction of the support rod 100 and points from the second end 130 to the first end 120; Figure 2 As shown, a first slot 110 for accommodating a breathing tube is provided on the support rod 100 along a first direction.

[0036] The first support assembly includes a first support plate 220 mounted on the first end portion 120, and a first through hole 222 capable of inserting the breathing tube is provided on the first support plate 220. Exemplarily, the first support plate 220 is hingedly mounted on the first end portion 120, so that the first support plate 220 can rotate relative to the first end portion 120; of course, the matching relationship between the first support plate 220 and the first end portion 120 is not limited to this, as long as the first end portion 120 can provide a mounting base for the first support plate 220. For example, in another embodiment, the first support plate 220 is snap-fitted and mounted on the first end portion 120; in another embodiment, the first support plate 220 is welded to the first end portion 120; in another embodiment, the first support plate 220 is glued to the first end portion 120.

[0037] Exemplarily, an end cover capable of sealing the first through hole 222 is detachably provided on the first through hole 222 .

[0038] Exemplarily, more than one first through hole 222 is provided. In one embodiment, two first through holes 222 are provided; in another embodiment, three first through holes 222 are provided.

[0039] During use, the support rod 100 can be installed upright on the operating table, and the first support plate 220 can be used to spread a sufficient area of ​​sterile cloth for the patient. Of course, the support rod 100 can be tilted to the operating table, and the tilt angle is set according to actual needs. It is understandable that the adjustable support head frame provided in the embodiment of the present application can not only be installed on the operating table to provide assistance for surgery, but can also be used in other scenarios that require support.

[0040] Exemplarily, the width of the first slot 110 is equal to the diameter of the breathing tube, so that the breathing tube can be stuck in the inner wall of the first slot 110, and the first slot 110 can limit the displacement of the breathing tube in the radial direction. The first slot 110 can reduce the volume of the breathing tube protruding from the support rod 100, prevent the breathing tube from blocking or interfering with other surgical equipment, and the first slot 110 can prevent the breathing tube from being completely bent and blocked, avoiding the risk of suffocation of the patient. Of course, the technical solution of installing the breathing tube in the first slot 110 is not limited to this. For example, in another embodiment, the breathing tube can also be installed in the first slot 110 by gluing or tying.

[0041] In one embodiment, the adjustable support head frame further includes a first fixing component, which is mounted on the second end 130 of the support rod 100. The support rod 100 is mounted on an operating table or other fixed foundation through the first fixing component.
