Description

TECHNICAL FIELD

[0001] The utility model relates to a medical tool especially to a support for preventing pressure injury of head and face during operation. BACKGROUND

[0002] In modern medicine, when patients suffer from laryngeal tumor, thyroid tumor, parotid tumor, neck tumor and other lesions, the laryngeal and neck parts of the patients need to be operated. During the operation, a sterile area needs to be formed because the operation site is close to the patient's head and face. Therefore, the patient's head and face need to be covered with multiple layers of sterile cloth for protection during the operation. Because the operation time is too long and the sterile cloth itself is thick, covering the head and face for a long time will cause pressure injury to the head and face. At the same time, the sterile cloth will also compress the oxygen tube, thereby causing pressure injury to the patient's head and face. Therefore, we provide a support for preventing pressure injury during operation to support the sterile cloth covering the patient's head and face during operation and prevent the sterile cloth from causing pressure injury to the patient's head and face.

[0020] Please see Figures 1 to 9As shown, a support for preventing intraoperative pressure injuries to the head and face includes a fixed plate 1, a movable plate 2, a fixed rod 3, a tightening block 4, a lifting bracket 5, a servo motor 6, a lead screw 7, a protective cover 8, a control switch 9, and a translation bracket 10. The fixed rod 3 passes through the fixed plate 1 and is fixed to the fixed plate 1. A guide rod 101 is symmetrically arranged on the bottom surface of the fixed plate 1. The movable plate 2 is slidably arranged on the fixed plate 1 through the guide rod 101. The fixed rod 3 passes through the movable plate 2. The bottom of the fixed rod 3 is provided with an external thread 301. The tightening block 4 is screwed to the bottom of the fixed rod 3 through the external thread 301. The lifting bracket 5 is slidably arranged inside the fixed rod 3. The servo motor 6 is fixed to the side of the fixed rod 3. The lead screw 7 is fixedly connected to the main shaft of the servo motor 6. The lifting bracket 5 is screwed to the lead screw 7. The control switch 9 is connected to the servo motor 6 through a wire. The protective cover 8 is arranged outside the servo motor 6 and the lead screw 7. The translation bracket 10 is slidably arranged on the top of the lifting bracket 5.

[0021] Specifically, the up-and-down movement of the movable plate 2 is controlled by tightening or loosening the tightening block 4. That is, when it is necessary to fix the entire device to the operating table, first loosen the tightening block 4 to increase the distance between the movable plate 2 and the fixed plate 1, then insert the fixed plate 1 into the upper edge of the bed board, and then tighten the tightening block 4. The tightening block 4 drives the movable plate 2 to move upward until the movable plate 2 is close to the bed board, thus completing the fixation of the device. The control switch 9 has a built-in charging power supply. The control switch 9 controls the forward and reverse rotation of the servo motor 6 through the wire. The servo motor 6 drives the lead screw 7 to rotate forward and reverse, and the lead screw 7 drives the lifting bracket 5 to move up and down inside the fixed rod 3. After the device is fixed to the operating table, the lifting support 5 is moved up and down by the control switch 9 until the lifting support 5 is adjusted to a suitable height from the patient's head and face. During the operation, the lifting support 5 can also be moved up and down by the control switch 9, thereby controlling the distance between the sterile cloth and the patient's head. The protective cover 8 is set outside the servo motor 6 and the lead screw 7 to prevent the sterile cloth from getting caught in the lead screw 7 when it rotates, ensuring that the servo motor 6 and the lead screw 7 operate smoothly. The translation support 10 can move back and forth on the lifting support 5. By moving the translation support 10 back and forth, the support range of the entire support can be adjusted.

[0022] The top of the lifting bracket 5 is also screwed with a locking screw 11, which passes through the lifting bracket 5 and the bottom of the locking screw 11 contacts the top of the translation bracket 10.

[0023] Specifically, the locking screw 11 limits the movement of the translation bracket 10, preventing the translation bracket 10 from sliding freely;

[0024] The lifting bracket 5 is symmetrically provided with guide blocks 501 on both sides, and the fixed rod 3 is symmetrically provided with guide grooves 302 on both sides. The guide blocks 501 can slide up and down in the guide grooves 302.

[0025] Specifically, the coordinated use of guide block 501 and guide groove 302 ensures that the lifting bracket 5 will not rotate when sliding up and down within the fixed rod 3, thereby improving the stability of the lifting bracket 5.

[0026] The front end of the translation bracket 10 is provided with an arc-shaped guide groove 1001, and arc-shaped support blocks 1002 are slidably arranged on both sides of the arc-shaped guide groove 1001;

[0027] Specifically, there is a certain damping between the arc-shaped support block 1002 and the arc-shaped guide groove 1001. The support area of ​​the translation bracket 10 can be controlled by pulling the arc-shaped support block 1002, thereby adapting to different head sizes of patients and achieving the best protection effect.

[0028] The upper surface of the movable plate 2 is symmetrically provided with anti-slip rubber pads 201;

[0029] Specifically, the anti-slip rubber pad 201 can increase the friction between the movable board 2 and the bed board, making the device more securely fixed.

[0030] The working principle and process of this utility model:

[0031] Please see Figures 1 to 9 As shown, during use, the entire device is fixed to the operating table. First, loosen the tightening block 4 to increase the distance between the movable plate 2 and the fixed plate 1. Then, insert the fixed plate 1 into the upper edge of the operating table and tighten the tightening block 4. The tightening block 4 will move the movable plate 2 upwards until the movable plate 2 is flush with the operating table, thus completing the device fixation. Turn on the control switch 9 to control the servo motor 6 to drive the lead screw 7 to rotate forward and backward. Adjust the height of the lifting bracket 5 according to the actual position of the patient's head until it is adjusted to a suitable height from the patient's head and face. Then, loosen the locking screw 11 and adjust the translation bracket 10 back and forth to adjust the distance between the arc-shaped guide groove 1001 and the patient's head and face. When the position is adjusted to a suitable level, tighten the locking screw 11. Then, adjust the length of the arc-shaped support block 1002 according to the size of the patient's head. After adjustment, cover the patient's head and face with a sterile cloth and complete the required surgery.

[0032] During surgery, the lifting support 5 can be moved up and down by the control switch 9, thereby controlling the distance between the sterile cloth and the patient's head. The protective cover 8 prevents the sterile cloth from being caught in the lead screw 7 when it rotates, ensuring the smooth operation of the servo motor 6 and the lead screw 7.
