[0003] During ultrasound-guided thyroid thermal ablation surgery, medical staff need to cover the rest of the body except the surgical site to prevent bacteria on the patient from spreading to the surgical site and increasing the patient's infection probability. In the prior art, medical staff use sterile sheets to cover the rest of the patient's body except the surgical site to prevent the spread of bacteria. However, when covering the head, the sterile sheet will block the medical staff's field of vision and the patient's breathing field of vision, which may easily cause the patient to feel nervous and anxious due to limited vision and poor breathing, and make the medical staff unable to observe the patient's facial expression and skin color at any time to timely discover and deal with possible problems and ensure the safe conduct of the operation. Therefore, the present invention provides a head protection and breathing support device for surgery to meet the needs. Summary of the Invention

[0019] By setting up a sealing component, when the overall size of the device frame is adjusted, the first sterile cloth, the second sterile cloth, and the third sterile cloth in the sealing component will seal the gaps caused by the adjustment of the overall size to prevent bacteria from spreading to the outside and affecting the patient's surgery. After the device frame loses the fixation of the fixing component, the elastic reset force of the elastic components such as the first elastic rope, the second elastic rope, and the elastic band in the sealing component will pull the device frame to contract and reset, so as to achieve the effect of automatically contracting and resetting the device frame.

[0020] By setting up a sealing component and a limiting component, the fourth sterile cloth and the third elastic rope in the sealing component can cooperate with the limiting parts, kits, blocks and limiting grooves in the installation component to seal the gap between the bottom of the device and the patient's neck, thereby ensuring the sealing of the device, preventing bacteria from spreading to the surgical site, and increasing the probability of infection at the patient's surgical site.

The plurality of elastic plates 8 are all slidably connected to the top of the second top plate 5, and the plurality of elastic plates 8 are respectively fixedly connected to the front plate 1, the side plate 2 and the rear plate 3 by screws. By setting up the fixing assembly, after the medical staff rotates the threaded cap 7, the threaded cap 7 will gradually be screwed onto the threaded rod 6 through the thread or gradually detached from the threaded rod. 6, so that the threaded cap 7 and the threaded rod 6 respectively drive the first top plate 4 and the second top plate 5 to move closer to or away from each other. When the first top plate 4 and the second top plate 5 move closer to each other, the first top plate 4 and the second top plate 5 will clamp and fix the elastic plate 8, so that the front plate 1, the side plate 2 and the rear plate 3 are fixedly connected to the first top plate 4 and the second top plate 5 through the elastic plate 8, and the device frame is locked and fixed. When the first top plate 4 and the second top plate 5 move away from each other, the first top plate 4 and the second top plate 5 will stop clamping and fixing the elastic plate 8, so that deformation and displacement can occur between the various components of the device frame, which is convenient for subsequent adjustment of the size of the device frame.

[0041] In this embodiment, if Figures 4 to 8As shown, the sealing assembly includes a first sterile cloth 9 fixedly connected to the end of the elastic plate 8 away from the threaded cap 7, the first sterile cloth 9 is plugged with a first elastic rope 10 and a second elastic rope 11, the front plate 1, the side plate 2, and the back plate 3 are provided with a second sterile cloth 12, an elastic belt 13 and a third sterile cloth 14, the bottom of the front plate 1, the side plate 2 and the back plate 3 is provided with a fourth sterile cloth 15, the first sterile cloth 9 and the fourth sterile cloth 15 are initially in a wrinkled state, and gradually unfold after being pulled, and the fourth sterile cloth 15 is plugged with a third elastic rope 16. By setting up the sealing assembly, when the various parts of the device frame are away from each other and the overall size of the device frame is adjusted, the distance between the first top plate 4, the second top plate 5 and the front plate 1, the side plate 2, and the back plate 3 will pull the first elastic rope 10 and the second elastic rope 11 to deform and stretch synchronously, so that the first elastic rope 10 and the second elastic rope 11 pulls the first sterile cloth 9 from the wrinkled state to the unfolded state, allowing the first sterile cloth 9 to seal the gaps caused by the distance, and the front plate 1, the side plate 2 and the back plate 3 are separated from each other, and the front plate 1 and the back plate 3 will pull the corresponding second sterile cloth 12 and the third sterile cloth 14 to gradually detach from the through groove 21 inside the side plate 2 and pull the elastic band 13 to stretch, so as to seal the gaps caused by the distance, and when the various parts of the device frame are separated from each other, the first sterile cloth 9, the second sterile cloth 12, and the third sterile cloth 14 will seal the gaps caused by the deformation to prevent bacteria from spreading to the outside and affecting the patient's surgery. When the device frame loses the fixation of the fixing component, the elastic reset force of the elastic components such as the first elastic rope 10, the second elastic rope 11, and the elastic band 13 in the sealing component will eventually pull the device frame to shrink and reset, so as to achieve the effect of automatically shrinking and resetting the device frame;

[0042] Furthermore, when sealing the gap between the bottom of the protection device and the patient's neck, the fourth sterile cloth 15 and the third elastic rope 16 in the sealing assembly can cooperate with the limiting piece 18, the kit 19, the card block 20 and the limiting groove 22 in the installation assembly. The medical staff puts the space created between the fourth sterile cloth 15 and the third elastic rope 16 on the patient's neck, so that the fourth sterile cloth 15 fits the patient's neck under the elastic action of the third elastic rope 16. The medical staff inserts the limiting piece 18 on the fourth sterile cloth 15 and the third elastic rope 16 into the limiting groove 22 on the outer wall of the side panel 2, and inserts the card block 20 on the kit 19 into the bottom of the front panel 1, and limits and fixes the outer wall of the fourth sterile cloth 15 and the third elastic rope 16, so that the outer wall of the fourth sterile cloth 15 and the third elastic rope 16 fits with the bottom of the front panel 1, the side panel 2 and the back panel 3, ensuring the sealing of the protection device, preventing bacteria from spreading to the surgical site, and increasing the probability of infection of the patient's surgical site.

[0043] In this embodiment, if Figures 2 to 9As shown, the installation assembly includes a connecting piece 17, a limiting piece 18 and a kit 19 fixedly connected to the fourth sterile cloth 15. The connecting piece 17, the limiting piece 18 and the kit 19 are thin sheets made of metal and bent and fixed on the outer wall of the part where the fourth sterile cloth 15 is connected to the third elastic rope 16. The connecting piece 17 is fixedly connected to the back plate 3 by screws. The top of the kit 19 is fixedly connected with a card block 20, and the card block 20 is inserted into the bottom of the front plate 1. A through groove 21 is opened inside the side panel 2, and a limiting groove 22 is opened on one side of the side panel 2. The limiting piece 18 is inserted into the inside of the limiting groove 22. The outer walls of the second sterile cloth 12 and the third sterile cloth 14 are fixedly connected with the first connecting piece 23 and the second connecting piece 24. The first connecting piece 23 and the second connecting piece 24 are both bent metal sheets fixed to the outer walls of the two long sides of the second sterile cloth 12 and the second sterile cloth 14. The elastic band 13 is inserted into the inside of the second connecting piece 24, and the two ends of the elastic band 13 are respectively connected to the second sterile cloth 12 and the third sterile cloth 14. Figure 9 As shown, a first card slot 25 is provided inside the front panel 1 and the back panel 3, and the outer contour of the first connecting member 23 is slightly larger than the inner contour of the first card slot 25, so that the first connecting member 23 and the first card slot 25 are clamped together with each other through elastic deformation (interference fit) therebetween, and a second card slot 26 is provided on the top of the front panel 1, the side panel 2 and the back panel 3, and the second sterile cloth 12 and the third sterile cloth 14 are clamped in the corresponding first card slot 25 on the front panel 1 and the back panel 3 through the connected first connecting member 23, and the second sterile cloth 12 and the third sterile cloth 14 are inserted into the through slot 21 inside the side panel 2 through the connected second connecting member 24, and the outer contour of the second connecting member 24 is adapted to the inner contour of the through slot 21, so that when the second connecting member 24 slides inside the through slot 21, no gap will be generated, thereby ensuring the sealing effect, and the elastic band 13 is inserted into the through slot 21 The first sterile cloth 9 and the first elastic cord 10 are inserted into the inside of the second slot 26. Since the overall contour of the second slot 26 is a narrow mouth and a wide belly and the contour of the connection part between the first sterile cloth 9 and the first elastic cord 10 is enlarged, the first sterile cloth 9 and the first elastic cord 10 can be slid into the inside of the second slot 26, so that the enlarged part of the connection between the first sterile cloth 9 and the first elastic cord 10 is inserted into the wide belly part of the second slot 26, and the first sterile cloth 9 is inserted into the narrow mouth part of the second slot 26. At this time, when the first sterile cloth 9 and the first elastic cord 10 are pulled, the enlarged part of the connection between the first sterile cloth 9 and the first elastic cord 10 will be blocked and limited by the narrow mouth of the first sterile cloth 9, ensuring the stability of the connection between the first sterile cloth 9 and the first elastic cord 10 and the front plate 1, side plate 2 and back plate 3, while the first sterile cloth 9 and the first elastic cord 10 are not affected when sliding inside the second slot 26.

[0044] In this embodiment, if Figure 1 、 Figure 2 and Figure 9As shown, the interior of the front plate 1 is fixedly connected with a silicone sheet 27, and a plurality of ventilation holes are opened on the silicone sheet 27 to ensure air circulation and prevent foreign matter from entering the interior of the protection device. The outer wall of the silicone sheet 27 is sprayed with an anti-fog coating to prevent the patient's breathing from generating fog to block the silicone sheet 27 and affect the field of vision of the patient and medical staff. A fitting part 28 is fixedly connected to one side of the silicone sheet 27. The silicone sheet 27 and the fitting part 28 are both made of highly translucent silicone material with good flexibility and antibacterial properties. They can fit the patient's face to improve comfort, and can withstand a certain impact force to protect the patient's face. At the same time, the high translucency is convenient for Medical staff can observe the patient's facial expression and breathing status at any time, which is conducive to the smooth progress of the operation. The fitting 28 can fit the patient's mouth and nose, separating the patient's mouth and nose from the rest of the space of the protection device. The silicone sheet 27 is fixedly connected to the side away from the fitting 28 with an elastic sheet 29. By setting the elastic sheet 29, medical staff can clip the breathing mask to the outside of the silicone sheet 27 through the elastic sheet 29 when necessary, and wrap the air holes on the silicone sheet 27, so that medical staff can supply oxygen and anesthesia to the patient through the curved mask air holes and the fitting 28, which is conducive to cooperating with the needs of the operation.

[0045] The working principle of the technical solution provided by the present invention is as follows: when a patient needs surgery, the protection device can first be adjusted to the maximum state and fixed by a fixing component (such as Figure 2 As shown, the safety device can be easily placed on the outer wall of the patient's head. The threaded cap 7 is then rotated to stop the fixing assembly from fixing the safety device. The elastic force of the first elastic cord 10, the second elastic cord 11, the elastic band 13 and other elastic components in the sealing assembly is restored to pull the safety device back to its original shape. The safety device frame stops when it fits the patient's head. This allows the device frame to be resized according to the patient's head, improving the versatility and adaptability of the safety device. The medical staff can then re-fix the safety device using the fixing assembly to prevent the elastic force of the first elastic cord 10, the second elastic cord 11, the elastic band 13 and other elastic components in the sealing assembly from restoring the device frame and causing continuous pressure on the patient's head, which would affect the patient's user experience. Finally, the medical staff can place the fourth sterile cloth 15 and the third elastic cord 16 around the patient's neck, lock the limiting member 18 into the limiting groove 22, and lock the block 20 on the sleeve 19 into the bottom of the front plate 1 to seal the gap at the patient's neck, prevent the spread of bacteria, and ensure the sealing of the safety device.

To provide a thorough understanding of the present invention, specific details are described in detail below in connection with the preferred embodiments of the present invention, but those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0047] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
