[0001] Embodiments of the present disclosure relate to the technical field of head and neck surgery, and more particularly, to a clinical head and neck surgery auxiliary retractor device. Background Art

[0002] A clinical head and neck surgery auxiliary retractor device is a medical device used in clinical head and neck surgeries to assist in retracting the surgical field during the operation. The main function of these devices is to provide necessary support and expansion, enabling surgeons to clearly observe and operate on the surgical area and ensuring the smooth progress of the operation.

[0003] The patent with the patent publication number CN215018124U relates to a surgical auxiliary retractor device used in an operating room, including a fixed seat, an extension rod, a steering wheel, and a retractor. The fixed seat is used to fix the entire retractor device to the edge of the operating table. One end of the extension rod is connected to the fixed seat, and the other end extends above the operating table and is connected to the steering wheel at its lower end. The lower end of the steering wheel is connected to the retractor and is used to adjust the direction of the retractor. The retractor is used to retract the surgical incision of the patient. This patent can be selectively installed or not installed beside the operating table in the operating room. Moreover, since it uses a steering wheel that can rotate, it can be used when retracting wounds in various directions. In the above patent, the lower end of the steering wheel is connected to the retractor and is used to adjust the direction of the retractor. The retractor is used to retract the surgical incision of the patient. When adjusting the retractor device, due to the possible differences in wounds among different injured patients, it may be relatively single in use and have low work efficiency. Summary of the Invention

[0004] To overcome the above defects, embodiments of the present disclosure provide a clinical head and neck surgery auxiliary retractor device, which solves the technical problem in the prior art that due to the possible differences in wounds among different injured patients, it may be relatively single in use and have low work efficiency.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a clinical head and neck surgery auxiliary retractor device, including a frame. A motor is fixedly installed above the frame, and a threaded rod is fixedly installed at the output end of the motor. A cross plate is slidably installed on the circumferential surface of the threaded rod. A first mounting plate is fixedly installed above the cross plate. A sliding plate is slidably installed on the side surface of the first mounting plate. An auxiliary block is fixedly installed at the bottom of the sliding plate. An adjusting device for adjusting the auxiliary block is arranged on the inner wall of the cross plate. The adjusting device includes a first groove, which is opened inside the cross plate. A slider is slidably installed inside the first groove. A first connecting plate is fixedly installed at the bottom of the slider. A first sliding groove is opened on the side surface of the first mounting plate. A baffle is slidably installed on the inner wall of the first sliding groove. An activity groove is opened on the side surface of the auxiliary block. An adjusting plate is slidably installed on the inner wall of the activity groove. A clamp is slidably installed inside the adjusting plate. A first adjusting rod is fixedly installed on the side surface of the clamp. A second adjusting rod is fixedly installed on the side surface of the adjusting plate. The slider will slide towards the inner wall of the first groove. When the first mounting plate is out of the range of the slider, the slider will return to its initial state under the action of a first spring and limit the first mounting plate, so as to adapt to the wound positions of different patients. By the fact that when the first mounting plate is out of the range of the slider, the slider will return to its initial state under the action of the first spring and limit the first mounting plate, so as to adapt to the wound positions of different patients, doctors can ensure the best exposure of the surgical area according to the individual differences of patients and surgical needs, while protecting the integrity of the surrounding tissues, reducing complications, and improving surgical efficiency. This can not only improve the success rate of the surgery, but also significantly improve the postoperative recovery process and quality of life of patients.

[0006] For example, in the clinical head and neck surgery auxiliary retractor device provided by at least one embodiment of the present disclosure, the side surface of the slider is set as a first inclined surface. A first spring is arranged between the inner wall of the first groove and the slider. The first spring is used to reset the slider, and the slider will slide towards the inner wall of the first groove.

[0007] The side surface of the baffle is set as a second inclined surface. A second spring is arranged between the bottom of the baffle and the inner wall of the first sliding groove. The second spring is used to reset the baffle, and the baffle moves towards the inner wall of the first sliding groove.

[0008] A limiting device for limiting the first connecting plate is provided on the side of the transverse plate. The limiting device includes a second mounting plate which is fixedly mounted on the side of the transverse plate. A limiting plate slidably penetrates through the interior of the second mounting plate. A second sliding groove is formed on the surface of the second mounting plate. A support plate is slidably mounted on the inner wall of the second sliding groove. An installation groove is formed on the side of the second sliding groove. A square plate is slidably mounted on the inner wall of the installation groove. An L-shaped plate is fixedly mounted above the square plate. When the L-shaped plate moves into the installation groove, it will drive the square plate at the bottom to move away from the support plate. When the square plate moves out of the range of the support plate, manually move the support plate away from the limiting plate. When the support plate moves away from the limiting plate, it will move out of the range of the limiting plate. When the limiting plate is not supported by the support plate, it will move downward. When the support plate moves downward, it will limit and block the first connecting plate. When the first connecting plate is limited, the slider will also be limited. Therefore, it can prevent the first mounting plate from accidentally touching and driving the slider to move, ensuring that the operation is more stable, safe and accurate, helping to improve the operation effect and reduce risks, thereby prolonging the service life of the device, improving the safety of the operation, and avoiding the situation of device instability caused by shaking.

[0009] According to another aspect, at least one embodiment of the present disclosure further provides a clinical head and neck surgery auxiliary retractor. The side surface of the square plate is provided with a second inclined surface, and the second inclined surface is used to limit the support plate by squeezing the second inclined surface of the square plate. When the support plate moves away from the limiting plate, it will move out of the range of the limiting plate.

[0010] A plurality of the limiting plates are provided, and the plurality of limiting plates are symmetrically distributed with the transverse plate as the center. The support plate moves away from the limiting plate.

[0011] A cleaning and disinfection device for cleaning and disinfecting the auxiliary block is provided on the surface of the auxiliary block. The cleaning and disinfection device includes a second connecting plate which is fixedly mounted above the auxiliary block. A third sliding groove is formed on the surface of the auxiliary block. A vertical plate is slidably mounted on the inner wall of the third sliding groove. A sweeping plate is slidably mounted at the bottom of the vertical plate. A second groove is formed on the side of the auxiliary block. An elastic sheet is slidably mounted on the inner wall of the second groove. When the vertical plate moves downward, it will drive the sweeping plate at the bottom to move downward. When the sweeping plate moves downward, it will move onto the surface of the elastic sheet. Then move the sweeping plate to wipe and disinfect the surface of the elastic sheet. When the disinfection is completed, the sweeping plate returns to the bottom of the vertical plate under the action of manual operation. Subsequently, the vertical plate will return to the initial state under the action of the third spring, so as not to affect the subsequent work. It is not only a necessary measure to protect the health and safety of patients, but also can prolong the service life of the device, improve the efficiency and safety during the operation, and meet the requirements of health regulations. It is the basis for ensuring the smooth progress of the operation and reducing the risks of infection and complications.

[0012] For example, in the clinical head and neck surgery auxiliary retractor device provided by at least one embodiment of the present disclosure, a third spring is provided between the vertical plate and the upper part of the auxiliary block. The third spring is used to reset the vertical plate, and when the vertical plate moves downward, it will drive the sweeping plate at the bottom to move downward.

[0013] The beneficial effects of the embodiments of the present disclosure are as follows: In the present disclosure, within the range where the first mounting plate leaves the slider, the slider will return to its initial state under the action of the first spring and limit the first mounting plate, so as to adapt to the wound positions of different patients. Doctors can ensure the best exposure of the surgical area according to the individual differences of patients and surgical requirements, while protecting the integrity of surrounding tissues, reducing complications, and improving surgical efficiency. This can not only improve the success rate of the surgery, but also significantly improve the postoperative recovery process and quality of life of patients.

[0014] In the present disclosure, the sliding plate will move downward when not limited by the baffle, so as to adapt to the necks of different patients. At the same time, the adjustment plate can be moved back and forth by adjusting the second adjusting rod, and then the fixture can be moved left and right by adjusting the first adjusting rod, so as to achieve the function of arbitrarily adjusting the position of the wound, making the surgery more precise, safe and comfortable. It can not only improve the operation efficiency of doctors, but also improve the postoperative recovery quality of patients, and extend the service life of the device.

[0015] In the present disclosure, when the support plate moves away from the limit plate and leaves the range of the limit plate, the limit plate will move downward when not supported by the support plate. When the support plate moves downward, it will limit and block the first connecting plate. When the first connecting plate is limited, the slider will be limited, so as to prevent the first mounting plate from accidentally touching and driving the slider to move, ensuring that the surgery is more stable, safe and accurate, helping to improve the surgical effect and reduce risks, thereby extending the service life of the device, improving the safety of the surgery, and avoiding the situation of device instability caused by shaking.

[0016] In the present disclosure, when the sweeping plate moves downward, it will move onto the surface of the elastic sheet, and then move the sweeping plate to wipe and disinfect the surface of the elastic sheet. After the disinfection is completed, the sweeping plate will return to the bottom of the vertical plate under the action of manual force. Subsequently, the vertical plate will return to its initial state under the action of the third spring, so as not to affect the subsequent work. This is not only a necessary measure to protect the health and safety of patients, but also can extend the service life of the device, improve the efficiency and safety during the surgery, and meet the requirements of hygiene regulations. It is the basis for ensuring the smooth progress of the surgery and reducing the risks of infection and complications. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0025] Such as Figures 1 to 7As shown, it shows a clinical head and neck surgery auxiliary retractor device in an embodiment of the present disclosure, including a frame 1. A motor 2 is fixedly installed above the frame 1. The output end of the motor 2 is fixedly installed with a threaded rod 3. A cross plate 4 is slidably installed on the circumferential surface of the threaded rod 3. A first mounting plate 5 is fixedly installed above the cross plate 4. A sliding plate 6 is slidably installed on the side surface of the first mounting plate 5. An auxiliary block 7 is fixedly installed at the bottom of the sliding plate 6. An adjusting device for adjusting the auxiliary block 7 is provided on the inner wall of the cross plate 4. The adjusting device includes a first groove 81, which is opened inside the cross plate 4. A slider 82 is slidably installed inside the first groove 81. A first connecting plate 84 is fixedly installed at the bottom of the slider 82. A first sliding groove 85 is opened on the side surface of the first mounting plate 5. A baffle 86 is slidably installed on the inner wall of the first sliding groove 85. An activity groove 88 is opened on the side surface of the auxiliary block 7. An adjusting plate 89 is slidably installed on the inner wall of the activity groove 88. A clamp 810 is slidably installed inside the adjusting plate 89. A first adjusting rod 811 is fixedly installed on the side surface of the clamp 810. A second adjusting rod 812 is fixedly installed on the side surface of the adjusting plate 89. The slider 82 will slide towards the inner wall of the first groove 81. When the first mounting plate 5 is out of the range of the slider 82, the slider 82 will return to its initial state under the action of a first spring 83 and limit the first mounting plate 5, so as to adapt to the wound positions of different patients.

[0026] In some examples, the side surface of the slider 82 is set as a first inclined surface. A first spring 83 is provided between the inner wall of the first groove 81 and the slider 82. The first spring 83 is used to reset the slider 82, and the slider 82 will slide towards the inner wall of the first groove 81.

[0027] The side surface of the baffle 86 is set as a second inclined surface. A second spring 87 is provided between the bottom of the baffle 86 and the inner wall of the first sliding groove 85. The second spring 87 is used to reset the baffle 86, and the baffle 86 moves towards the inner wall of the first sliding groove 85.

[0028] For example, as Figures 1 to 7As shown in the figure, start the motor 2. The rotation of the output end of the motor 2 drives the rotation of the threaded rod 3. The rotation of the threaded rod 3 drives the horizontal plate 4 on its surface to slide downward. The downward sliding of the horizontal plate 4 drives the upper mounting plate 1 5 to move downward. The downward movement of the mounting plate 1 5 drives the sliding plate 6 to move downward. The downward movement of the sliding plate 6 drives the auxiliary block 7 at the bottom to move downward. The downward movement of the auxiliary block 7 contacts the wound of the surgical patient. During this process, manually push the mounting plate 1 5 inward. The inward movement of the mounting plate 1 5 contacts the inclined surface 1 of the slider 82. When the slider 82 is squeezed, the slider 82 slides toward the inner wall of the groove 1 81. When the mounting plate 1 5 leaves the range of the slider 82, the slider 82 returns to its initial state under the action of the first spring 83 and limits the mounting plate 1 5 to adapt to the wound positions of different patients. Doctors can ensure the best exposure of the surgical area according to the individual differences of patients and surgical needs, while protecting the integrity of the surrounding tissues, reducing complications, and improving surgical efficiency. This can not only improve the success rate of the surgery, but also significantly improve the postoperative recovery process and quality of life of patients. Subsequently, when the neck sizes of patients are different, the doctor moves the baffle 86 toward the inner wall of the first chute 85. At the same time, the sliding plate 6 moves downward without being limited by the baffle 86 to adapt to the neck sizes of different patients. When the wound positions are inconsistent, the adjustment plate 89 can be moved back and forth by adjusting the second adjusting rod 812. Subsequently, the fixture 810 can be moved left and right by adjusting the first adjusting rod 811 to achieve the function of arbitrarily adjusting the position of the wound, making the surgery more precise, safe, and comfortable. This can not only improve the operation efficiency of doctors, but also improve the postoperative recovery quality of patients and extend the service life of the device.

[0029] As Figures 1 to 7 shown, it shows that in another embodiment of the present disclosure, a limiting device for limiting the connecting plate 1 84 is provided on the side surface of the horizontal plate 4. The limiting device includes a second mounting plate 91. The second mounting plate 91 is fixedly installed on the side surface of the horizontal plate 4. A limiting plate 92 slides through the inside of the second mounting plate 91. A second chute 93 is formed on the surface of the second mounting plate 91. A support plate 94 is slidably installed on the inner wall of the second chute 93. A mounting groove 95 is formed on the side of the second chute 93. A square plate 96 is slidably installed on the inner wall of the mounting groove 95. An L-shaped plate 97 is fixedly installed above the square plate 96. The inward movement of the L-shaped plate 97 into the mounting groove 95 drives the bottom square plate 96 to move away from the support plate 94. When the square plate 96 leaves the range of the support plate 94, manually move the support plate 94 away from the limiting plate 92.

[0030] The side surface of the square plate 96 is provided with an inclined surface 2. The inclined surface 2 is used to limit the support plate 94 by squeezing the inclined surface 2 of the square plate 96. The movement of the support plate 94 away from the limiting plate 92 will leave the range of the limiting plate 92. In some examples, a plurality of limiting plates 92 are provided, and the plurality of limiting plates 92 are symmetrically distributed with the transverse plate 4 as the center, and the support plate 94 moves away from the limiting plate 92.

[0031] A cleaning and disinfection device for cleaning and disinfecting the auxiliary block 7 is provided on the surface of the auxiliary block 7. The cleaning and disinfection device includes a second connecting plate 101. The second connecting plate 101 is fixedly installed above the auxiliary block 7. A third chute 102 is formed on the surface of the auxiliary block 7. A vertical plate 103 is slidably installed on the inner wall of the third chute 102. A sweeping plate 105 is slidably installed at the bottom of the vertical plate 103. A second groove 106 is formed on the side surface of the auxiliary block 7. A elastic piece 107 is slidably installed on the inner wall of the second groove 106. When the vertical plate 103 moves downward, it will drive the sweeping plate 105 at the bottom to move downward. When the sweeping plate 105 moves downward, it will move onto the surface of the elastic piece 107, and then move the sweeping plate 105 to wipe and disinfect the surface of the elastic piece 107.

[0032] A third spring 104 is arranged between the upper part of the vertical plate 103 and the auxiliary block 7. The third spring 104 is used to reset the vertical plate 103. When the vertical plate 103 moves downward, it will drive the sweeping plate 105 at the bottom to move downward.

[0033] For example, as Figures 1 to 7 shown, when the slider 82 needs to be limited from moving, the L-shaped plate 97 can be manually pulled into the installation groove 95. When the L-shaped plate 97 moves into the installation groove 95, it will drive the square plate 96 at the bottom to move away from the support plate 94. When the square plate 96 leaves the range of the support plate 94, manually move the support plate 94 away from the limiting plate 92. When the support plate 94 moves away from the limiting plate 92, it will leave the range of the limiting plate 92. When the limiting plate 92 is not supported by the support plate 94, it will move downward. When the support plate 94 moves downward, it will limit and block the first connecting plate 84. When the first connecting plate 84 is limited, it will limit the slider 82, so as to prevent the first installation plate 5 from accidentally touching and driving the slider 82 to move, to ensure that the operation is more stable, safe and accurate, which helps to improve the operation effect and reduce risks, thereby extending the service life of the equipment, improving the safety of the operation, and avoiding the situation that the equipment is unstable due to shaking.

[0034] Meanwhile, when the bottom of the auxiliary block 7 needs to be disinfected and cleaned, the operator moves the vertical plate 103 downward. The downward movement of the vertical plate 103 will drive the bottom sweeping plate 105 downward. The downward movement of the sweeping plate 105 will move onto the surface of the elastic piece 107. Subsequently, the sweeping plate 105 is moved to wipe and disinfect the surface of the elastic piece 107. After the disinfection is completed, the sweeping plate 105 returns to the bottom of the vertical plate 103 under the action of the operator. Subsequently, the vertical plate 103 will return to its initial state under the action of the third spring 104, so as not to affect the subsequent work. This is not only a necessary measure to protect the health and safety of patients, but also can extend the service life of the equipment, improve the efficiency and safety during the operation, and meet the requirements of hygiene regulations. It is the basis for ensuring the smooth progress of the operation and reducing the risk of infection and complications.
