[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figure 1-5 This embodiment provides a head and face isolation frame for anterior cervical spine surgery, including a bed body 1.

[0023] Specifically, the bed body 1 is configured as a hospital bed for performing surgery on a patient. Figure 1 As shown, a positioning pillow 11 is fixedly connected to the upper end of the bed body 1. Figure 4 As shown, a slot is provided at the upper end of the bed body 1, and the lower end of the positioning pillow 11 is fixedly inserted into the slot. Different patients have different necks, and positioning pillows 11 of different widths and heights can be replaced according to necks of different lengths. After the patient lies on the bed body 1, he moves his body so that his neck is located on the positioning pillow 11, thereby positioning the patient's head.

[0024] like Figure 1 As shown, an isolation frame is provided above the bed 1 to separate the patient's head and neck. Specifically, the isolation frame includes an isolation sheet 2 and a tightening rope 21, wherein two tightening ropes 21 are provided, and the two tightening ropes 21 are respectively fixedly connected to the two ends of the isolation sheet 2. Two sliding holes are provided at the upper end of the bed 1, and the tightening ropes 21 are slidably inserted in the sliding holes. In order to tighten the isolation frame, a winding mechanism 3 is provided inside the bed 1.

[0025] Specifically, the winding mechanism 3 includes a rotating rod 31 and a winding roller 32, wherein two winding rollers 32 are provided, the rotating rod 31 is rotatably installed in the bed body 1, the two winding rollers 32 are fixedly sleeved on the outer wall of the rotating rod 31, and one end of the tightening rope 21 extending into the bed body 1 is fixedly connected to the outer wall of the winding roller 32.

[0026] When in use, the isolation plate 2 is moved to fit the patient's chin, and the rotating rod 31 is rotated to drive the two winding rollers 32 to rotate synchronously, and then the two tightening ropes 21 are synchronously wound, so that the isolation plate 2 applies a pulling force to the patient's chin, and the patient's head is slightly lifted. At the same time, the patient's head and neck are separated by the isolation plate 2, so that the front of the patient's neck can be fully exposed for surgery.

[0027] In order to facilitate the rotation of the rotating rod 31, a rocker 33 is rotatably installed on the side of the bed body 1. Figure 1 , Figure 2 and Figure 3 As shown, one end of the rocker arm 33 is fixedly connected to a sliding rod 331, one end of the rotating rod 31 is provided with a sliding groove, the sliding rod 331 is slidably inserted in the sliding groove of the rotating rod 31, and the end surface of the rocker arm 33 facing the bed body 1 is fixedly connected to a fixed block 332, and the side of the bed body 1 is provided with a plurality of sockets matching the fixed block 332, and the plurality of sockets are evenly distributed in a circular array with the rotating rod 31 as the center.

[0028] When in use, rotating the rocker 33 can drive the rotating rod 31 to rotate. After the isolation plate 2 is tightened to fit the patient, the rocker 33 is moved to make the sliding rod 331 slide in the sliding groove of the rotating rod 31, so that the rocker 33 fits the side of the bed body 1. At this time, the fixing block 332 is engaged in a socket on the side of the bed body 1, thereby fixing the rocker 33. The fixing of the rocker 33 can prevent the rotating rod 31 from rotating.

[0029] In order to further fix the patient's head, a baffle 4 is slidably installed on the upper end of the bed body 1. Specifically, Figure 4 As shown, a rail 12 is slidably installed on the upper end of the bed body 1, and two rails 12 are provided. The lower end of the baffle 4 is slidably engaged with the rail 12, and the rail 12 limits the movement of the baffle 4, so that the baffle 4 can slide stably on the upper end of the bed body 1.

[0030] like Figure 5 As shown, the end face of the baffle 4 is fixedly connected with a protrusion, and the protrusion is set to two, and the two protrusions fit the upper end of the rail 12, and the upper end of the protrusion is threadedly connected with a knob 41. When in use, the baffle 4 is moved to fit the patient's head, and the knob 41 is tightened to make the lower end of the knob 41 contact the rail 12, thereby increasing the reverse force between the knob 41 and the rail 12, that is, forming a damping force to fix the protrusion. The fixing of the protrusion means fixing the baffle 4, and the baffle 4 further limits the patient's head.
