DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 12 The present invention provides a medical thyroid tumor surgery posture adjustment and fixation device, comprising: a base plate 1, the base plate 1 in the present application is provided with mounting holes around it, which is convenient for installing the base plate 1 on equipment such as a bed, thereby increasing the applicability of the device, and a fixing plate 2 for clamping a patient is provided on the base plate 1; The utility model also comprises: an adjusting member, a sliding plate 3 which slides horizontally in the base plate 1, the sliding plate 3 is rotatably connected with the bottom of the fixed plate 2, the sliding plate 3 always keeps sliding horizontally, and the angle will not change, and the sliding plate 3 moves horizontally with the slider 19, a limiting plate 4 which is rotatably connected with the fixed plate 2 and presses against the fixed plate 2 is rotatably connected to the sliding plate 3, a moving member which drives the two fixed plates 2 to move relative to each other is provided between the bottoms of the two fixed plates 2, a pressing plate 5 which presses against the patient's body parts is provided between the two fixed plates 2, a limiting member is provided between the tops of the two fixed plates 2, and the limiting member enables the pressing plate 5 to move, a connecting block 6 which is slidably matched with the connecting block 6 is provided on the pressing plate 5 through the adjusting member, a rotating plate 7 is rotatably connected between the connecting block 6 and the top of the fixed plate 2, and the adjusting member is used to make the pressing plate 5 slide along the connecting block 6 to adjust its position; A clamping plate 8 rotatably connected to the fixing plate 2, the airbag being clamped on the clamping plate 8, and a fixing piece for fixing the clamping plate 8 is provided on the fixing plate 2; The thyroid gland is often located in the head and neck area. The surgical position for thyroid gland, especially the supine position with the head and neck tilted back and the shoulders raised, can fully expose the anterior neck area and make the thyroid gland and its surrounding tissues clearly visible. The adjustment of the body position helps the doctor to perform fine dissection and separation operations during the operation, thus improving the accuracy and safety of the operation. Thyroid surgery posture adjustment is of great significance for surgical operation, reducing postoperative complications, improving patient comfort and cooperation, and promoting postoperative recovery. The details are as follows: During the operation: In this application, specifically, the entire device is first put into the patient's head and neck, that is, the two fixing plates 2 are located on both sides of the patient's head and neck, and the pressing plate 5 is pressed against the throat of the patient's head and neck. Through the four-sided action of the base plate 1, the fixing plate 2 and the pressing plate 5, the entire head and neck is fully fixed; The width of the fixing plate 2 and the pressing plate 5 is small, so that the entire head and neck area is not blocked, and part of the head and neck is not blocked. Before the operation, the fixing plate 2 and the pressing plate 5 fix the position of the patient's head and neck, and can avoid the operation position (corresponding to the thyroid disease position), thus ensuring the fixation effect without affecting the operation; When treating the location of the thyroid disease, the angle needs to be adjusted to facilitate the doctor to perform the operation. When the position needs to be adjusted, the limiting plate 4 is rotated so that the top of the limiting plate 4 is firmly pressed against the fixing plate 2 to ensure that the fixing plate 2 does not tilt in the opposite direction; Finally, the screw rod 18 is rotated to make the sliders 19 approach each other, and the bottom ends of the two fixing plates 2 approach each other to squeeze and fix the patient's body parts. At the same time, under the action of the limiter, the top ends of the fixing plates 2 approach each other, thereby ensuring that the fixing plates 2 fix the patient's body parts. Wherein, under the action of the limiting plate 4, the fixing plate 2 is ensured not to tilt in the reverse direction. As the two fixing plates 2 approach each other, the rotating plate 7 tilts, so that the pressing plate 5 can press and fix other parts of the patient's body tightly.

[0020] Postoperative recovery process: Appropriate body position adjustment can also promote the patient's postoperative recovery. For example, after surgery, the patient needs to lie flat without a pillow. The fixation plate 2 and the pressure plate 5 can keep the patient in a supine position with a pillow, which helps to reduce neck pressure and promote wound healing. At the same time, combined with measures such as pressurization of the anterior cervical incision with sandbags, it can further reduce the occurrence of postoperative complications and accelerate the patient's recovery process. The fixed plate 2 is an elastic plate with an arc-shaped structure. A plurality of grooves 9 are provided on the side of the fixed plate 2 to engage with the end of the limit plate 4. The rotation between the limit plate 4 and the sliding plate 3 is friction rotation. In the present application, the limiting plate 4 is rotated to adjust the angle of the limiting plate 4 so that the top of the limiting plate 4 is pressed against one of the grooves 9 of the fixing plate 2. The limitation of the limiting plate 4 ensures the inclination angle of the fixing plate 2, thereby preventing the fixing plate 2 from tilting in the opposite direction under the reaction of the patient's body, thereby affecting the fixing effect of the fixing plate 2.

[0021] The adjusting member includes a connecting plate 10 connected and fixed to the pressure plate 5. The connecting plate 10 is a U-shaped structure. The connecting plate 10 and the connecting block 6 are slidably matched. The pressure plate 5 is a flexible plate. A slide plate 11 is fixedly connected to the connecting block 6. The connecting plate 10 is moved synchronously by moving the pressure plate 5. The connecting plate 10 moves along the connecting plate, so that the flexible pressure plate 5 is moved and adjusted to a suitable position.

[0022] The connecting block 6 is a step structure, and a matching plate 12 that slides with the slide plate 11 is fixedly connected to the connecting plate 10. The bottom of the matching plate 12 slides with the bottom step structure of the connecting block 6 to ensure smooth sliding of the connecting block 6 and the connecting plate 10. Baffles 13 are fixedly connected at both ends of the connecting plate 10 to prevent the connecting block 6 from detaching from the connecting plate 10.

[0023] The adjusting member also includes a threaded rod 14, a sliding groove 15 is provided on the matching plate 12, the threaded rod 14 is threadedly connected with the slide plate 11 and the bottom step structure of the connecting block 6, and the bottom end of the threaded rod 14 is pressed and matched with the connecting plate 10; In the present application, the threaded rod 14 is first screwed in the reverse direction so that the bottom end of the threaded rod 14 does not contact the connecting plate 10; Then, the connecting plate 10 is slid along the connecting block 6 to adjust its position through the movable pressing plate 5 and the connecting plate 10, and at this time, the threaded rod 14 slides relative to the sliding groove 15; Finally, when the adjustment position of the pressure plate 5 is completed, the threaded rod 14 is tightened so that the bottom end of the threaded rod 14 presses against the connecting plate 10, and the connecting block 6 moves slightly upward and is tightly pressed and fixed with the matching plate 12, thereby firmly ensuring the position of the pressure plate 5.

[0024] A rotating groove 16 is provided on the connecting block 6, and two meshing wheels 17 that mesh with each other are rotatably connected in the rotating groove 16. The sides of the meshing wheels 17 are fixedly connected to the rotating plate 7. Through the cooperation of the two meshing wheels 17, the rotation angles of the two rotating plates 7 are always consistent, so that the pressing plate 5 can stably press the patient's body part.

[0025] The moving part includes two screws 18 rotatably connected to the base plate 1, the ends of the two screws 18 are connected and fixed, and the thread directions are oppositely distributed, the screws 18 are threadedly connected with a slider 19 that slides horizontally in the base plate 1, the bottom of the fixed plate 2 is rotatably connected to the slider 19, and the base plate 1 is provided with a limiting groove 20 that movably cooperates with the fixed plate 2 and the limiting plate 4; In the present application, the screw 18 is rotated in its original position by self-rotating the screw 18. Since the slider 19 is restricted in the limiting groove 20 to slide horizontally and cannot rotate at an angle, the two sliders 19 are brought close to each other, driving the bottom ends of the fixing plates 2 to approach each other along the limiting groove 20, thereby bringing the two fixing plates 2 close to each other to fix the patient's body parts.

[0026] The limiting member includes a limiting frame 21 and a limiting rod 22 rotatably connected to the fixed plate 2. The limiting rod 22 slides in the limiting frame 21. A tension spring 23 is hung between the two limiting rods 22. The rotating plate 7 is rotatably connected to the limiting rod 22. In the present application, when the screw 18 rotates to bring the two fixing plates 2 closer to each other and fix the patient's body parts, under the action of the tension spring 23, the tops of the fixing plates 2 are brought closer to each other, and the fixing plates 2 rotate relative to the slider 19, so that the arc-shaped fixing plates 2 are pressed against and fix the patient's body parts, wherein the tops of the two fixing plates 2 are brought closer to each other, causing the rotating plate 7 to rotate, so that the pressing plate 5 is tightly pressed against other parts of the patient's body, further ensuring the fixing effect.

[0027] The fixing member includes a self-rotating rod 24 connected and fixed to the clamping plate 8, the self-rotating rod 24 is connected and fixed to the fixing plate 2, a fixing plate 25 is fixedly connected to the self-rotating rod 24, a plurality of plug holes 26 are provided on the fixing plate 25, a plug plate 27 is movably plugged into the fixing plate 2 through an elastic pull rope, and a plug rod 28 plugged and matched with the plug hole 26 is fixedly connected to the middle of the plug plate 27; In the present application, the plug plate 27 is first pulled out to disengage the plug rod 28 from the plug hole 26, thereby releasing the fixation of the fixed plate 25; Then the clamping plate 8 is rotated, and the rotation rod 24 and the fixed plate 25 rotate synchronously, so as to adjust the angle of the fixed clamping plate 8, so as to facilitate the adjustment of the angle of the airbag on the clamping plate 8, and to press and fix the tumor part of the patient; Finally, loosen the plug plate 27, and under the action of the elastic pull rope, reinsert the plug plate 27 into the fixing plate 2, and insert the insertion rod 28 into the insertion hole 26 again to fix the angle of the fixing plate 25, thereby fixing the clamping plate 8 and the airbag after the adjusted angle, wherein other recessed parts of the patient's body are fixed by the airbag, thereby increasing the fixing area and the fixing effect.
