Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0045] As described in the background art, the splicing and supporting effect of the nursing pad is poor, and it does not have the function of free shaping. The shaping accuracy formed by splicing and the fitting position accuracy with the patient's body are low.

[0046] To solve this technical problem, the present invention provides a general operating table nursing pad for surgeries, which is applicable to the free splicing combination and shaping of nursing pads. It can freely shape the nursing pad into the required shape according to actual use to support the patient. At the same time, during the shaping process, it can form a nursing pad that completely fits the patient's body position according to the actual body shape of the patient.

[0047] Specifically, please refer to Figures 1 - 11 , the general operating table nursing pad for surgeries specifically includes:

[0048] There are four groups of strip pads 1 spliced to form a square. Inside the square strip pad 1, a combined pad 2 is embedded and combined. At the splicing joints at both ends of the strip pad 1, a matching adjustment groove 3 is provided. In the middle of the strip pad 1, there is a telescopic shaping cylinder 4. At the center of the interior of the strip pad 1, a shaping steel wire 5 is passed through. The shaping steel wire 5 is respectively passed through the interior of the strip pad 1, the matching adjustment groove 3, and the telescopic shaping cylinder 4. The shaping steel wire 5 connects the four groups of strip pads 1 spliced to form a square. At both ends in the middle of the strip pad 1, there are symmetric tensioning mechanisms 6. The shaping steel wire 5 is passed through the interior of the tensioning mechanism 6;

[0049] The tensioning mechanism 6 is divided into a winding and resetting member 7 and a one-way positioning member 8. The shaping steel wire 5 is passed through the interior of the winding and resetting member 7. The one-way positioning member 8 is inserted and combined with the winding and resetting member 7. The one-way positioning member 8 drives the winding and resetting member 7 to position and rotate to wind up the shaping steel wire 5. The shaping steel wire 5 winds up and tensions the strip pad 1 to form a square. The one-way positioning member 8 drives the winding and resetting member 7 to slide and separate from the one-way positioning member 8. After the winding and resetting member 7 separates from the one-way positioning member 8, it is pulled by the shaping steel wire 5 to release the shaping steel wire 5. After the winding and resetting member 7 releases the shaping steel wire 5, the elastic force drives the winding and resetting member 7 to combine with the one-way positioning member 8.

[0050] The general operating table nursing pad for surgeries provided by the present invention, through the nursing pad formed by splicing and combining four groups of strip pads 1, can meet the combined use requirements of nursing pads of various shapes. At the same time, each strip pad has a telescopic shaping cylinder 4 in the middle, which enables the strip pad 1 to have special-shaped shaping while splicing and shaping. By using the tensioning mechanism 6 to tension and fix the shaped strip pad 1, the nursing pad can have the function of accurately fitting the patient's body position, which is beneficial to improving the comfort and support stability of the patient during surgery.

[0066] At both ends of each strip-shaped pad 1, a tensioning mechanism 6 is provided, which can achieve the fitting tightness when the strip-shaped pad 1 is combined with both sides and itself, thereby improving the stability of the strip-shaped pads 1 after combination. The tensioning mechanism 6 itself can automatically lock when tensioning the shaping wire 5. At the same time, when releasing the shaping wire 5, the winding and resetting member 7 can be quickly separated to complete the reverse release of the shaping wire 5, and the combination of the winding and resetting member 7 and the one-way positioning member 8 can be automatically completed, facilitating the quick use of the tensioning mechanism 6.

[0067] The usage process of an operating table nursing pad universal for surgeries provided by the present invention is as follows:

[0068] According to actual usage requirements, the four groups of strip-shaped pads 1 are spliced. The four groups of strip-shaped pads 1 can be spliced into shapes such as rectangles, squares, and staggered arrangements by cooperating with the horizontal groove 32 and the vertical groove 31 of the adjustment groove 3. By using the telescopic shaping cylinder 4 inside the strip-shaped pad 1, the strip-shaped pad 1 can be bent into an arc. By the ends of the rigid mating heads 13 abutting against each other, the strip-shaped pads 1 can form various shapes such as rings and arcs, thus being applicable to various scenarios. At the same time, according to the patient's body type, the strip-shaped pads 1 can be fitted around the patient's body, making the strip-shaped pads 1 fit the patient's skin to form a precise shaping angle.

[0069] It should be noted that when the strip-shaped pad 1 is bent, the shaping pieces 42 inside the telescopic shaping cylinder 4 will move along with the bending of the telescopic shaping cylinder 4, so as to ensure that the plastic region of the strip-shaped pad 1 can be shaped.

[0070] After the four groups of strip-shaped pads 1 are spliced into the required shape, the driving sleeve 81 is rotated to drive the reel 71 to rotate. The rotation of the reel 71 will simultaneously drive the one-way positioning teeth 84 and the winding roller 72 to rotate. The rotation of the winding roller 72 will wind the shaping wire 5 passing through the wire perforation 723 inside, so as to tension the shaping wire 5.

[0071] When the shaping wire 5 is wound and tensioned, the shaping wire 5 passing through the strip-shaped pad 1 and the telescopic shaping cylinder 4 will apply a tensioning force to the shaping pieces 42. Since there are conical friction blocks 43 on the surface of the shaping pieces 42, the shaping pieces 42 will be fitted and shaped when being subjected to the tension force, enabling the plastic region in the middle of the strip-shaped pad 1 to be shaped.

[0072] When all the strip-shaped pads 1 are shaped, they can be used.

[0073] It should be noted that when the driving sleeve 81 rotates, the one-way positioning teeth 84 on the outer wall of the driving sleeve 81 will rotate, applying a thrust to the positioning lock block 85. The positioning lock block 85 will push the return spring 86 under the thrust, and the return spring 86 will contract to store energy. When the rotation of the one-way positioning teeth 84 is completed, the return spring 86 will release the thrust to push out the positioning lock block 85, so that the positioning lock block 85 is locked inside the one-way positioning teeth 84, completing the one-way locking of the driving sleeve 81.

[0074] When the strip-shaped pad 1 needs to be reshaped after use, the separation push piece 871 can be directly pressed. The separation push piece 871 will push the separation push rod 87 to move. The movement of the separation push rod 87 will push the scroll 71 to slide inside the tension driving groove 14. At the same time, the insertion positioning strip 74 at one end of the scroll 71 will be separated from the insertion groove 83 of the Chahe positioning cap. When the scroll 71 is separated from the driving sleeve 81, the scroll 71 and the winding roller 72 will be pulled by the shaping wire 5 to rotate reversely.

[0075] At this time, the release of the shaping wire 5 can be completed. After the shaping wire 5 is released, the strip-shaped pad 1 can be freely moved to continue the shaping use.

[0076] After the scroll 71 releases the shaping wire 5, when the separation push piece 871 is released, the scroll 71 will be pushed by the propulsion spring 733, so that the scroll 71 has a force to move towards the one-way positioning member 8, and the insertion positioning strip 74 at one end of the scroll 71 will automatically be inserted and connected with the insertion groove 83, facilitating the use of the driving sleeve 81 to drive the winding and resetting member 7.

[0077] It should be noted that when the separation push piece 871 pushes the separation push rod 87 to move, since the winding roller 72 slides on the outer wall of the scroll 71 through the positioning slider 721 in the middle, the sliding of the scroll 71 will not be affected by the tension of the shaping wire 5 winding, so that the separation push rod 87 can be easily pushed to complete the release of the shaping wire 5.

[0078] When using the strip-shaped pad 1 as a flat pad body, the strip-shaped pad 1 can be shaped into a square, and the combined pad 2 can be placed inside the embedding groove formed in the middle of the strip-shaped pad 1. It can also be sleeved outside the strip-shaped pad 1 through the combined belt 21 to ensure the combined stability between the combined pad 2 and the strip-shaped pad 1.
