Description

Technical Field

[0001] This invention relates to the field of assistive dislocation technology in clinical head and neck surgery, specifically to an assistive dislocation device for clinical head and neck surgery. Background Technology

[0002] Clinical head and neck surgery assistive retraction devices are medical instruments used to assist in opening the surgical field during head and neck surgery. The main function of these devices is to provide the necessary support and expansion, enabling surgeons to clearly observe and manipulate the surgical area, ensuring the smooth progress of the surgery.

[0003] Patent publication number CN215018124U relates to a clinical head and neck surgery auxiliary retraction device, including a fixed base, an extension rod, a steering wheel, and a retraction frame. The fixed base is used to fix the entire retraction device to the side of the operating table. One end of the extension rod is connected to the fixed base, and the other end extends above the operating table, with its lower end connected to the steering wheel. The lower end of the steering wheel is connected to the retraction frame and is used to adjust the direction of the retraction frame. The retraction frame is used to open the patient's surgical incision. This patent provides a surgical auxiliary retraction device for use in the operating room. This patent allows for optional installation beside the operating table in the operating room, and because it uses a steering wheel that can rotate, it can be used for wound opening in various directions.

[0004] In the aforementioned patent, the lower end of the steering wheel is connected to the spreading frame and used to adjust the direction of the spreading frame. The spreading frame is used to spread open the surgical incision of the patient. When adjusting the spreading device, since the wounds of different patients may be different, it may lead to a relatively monotonous use and low work efficiency. Therefore, a clinical head and neck surgery auxiliary spreading device with an adjustment device was designed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a clinical head and neck surgery auxiliary dissect device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clinical head and neck surgery auxiliary retraction device, comprising a frame, a motor fixedly mounted on the top of the frame, a threaded rod fixedly mounted on the output end of the motor, a horizontal plate slidably mounted on the circumferential surface of the threaded rod, a mounting plate fixedly mounted on the top of the horizontal plate, a sliding plate slidably mounted on the side of the mounting plate, an auxiliary block fixedly mounted on the bottom of the sliding plate, and an adjustment device for adjusting the auxiliary block provided on the inner wall of the horizontal plate. The adjustment device includes a groove, which is formed inside the horizontal plate, and a sliding block is slidably mounted inside the groove. The slider has a connecting plate fixedly installed at its bottom. A groove is formed on the side of the connecting plate. A baffle is slidably installed on the inner wall of the groove. An adjustable plate is slidably installed on the inner wall of the adjustable groove. A clamp is slidably installed inside the adjustable plate. An adjusting rod is fixedly installed on the side of the clamp. An adjusting rod is fixedly installed on the side of the adjustable plate. The slider slides towards the inner wall of the groove. When the connecting plate moves away from the slider, the slider returns to its initial state under the action of a spring and limits the position of the connecting plate, thus adapting to different wound positions of patients.

[0007] According to the above technical solution, the side of the slider is set as an inclined surface, and a spring is provided between the inner wall of the groove and the slider. The spring is used to reset the slider, and the slider will slide towards the inner wall of the groove.

[0008] According to the above technical solution, the side of the baffle is set as a second inclined surface, and a second spring is provided between the bottom of the baffle and the inner wall of the first slide groove. The second spring is used to reset the baffle, and the baffle moves towards the inner wall of the first slide groove.

[0009] According to the above technical solution, a limiting device for limiting the connecting plate is provided on the side of the horizontal plate. The limiting device includes a second mounting plate, which is fixedly installed on the side of the horizontal plate. The limiting plate slides through the interior of the second mounting plate. A second sliding groove is provided on the surface of the second mounting plate. A support plate is slidably installed on the inner wall of the second sliding groove. An installation groove is provided on the side of the second sliding groove. A square plate is slidably installed on the inner wall of the installation groove. An L-shaped plate is fixedly installed on the top of the square plate. When the L-shaped plate moves into the installation groove, it will drive the bottom square plate to move away from the support plate. When the square plate leaves the range of the support plate, the support plate is manually moved away from the limiting plate.

[0010] According to the above technical solution, the side of the square plate is set as inclined surface three. Inclined surface three is used to limit the support plate by pressing the inclined surface three of the square plate. When the support plate moves away from the limiting plate, it will leave the range of the limiting plate.

[0011] According to the above technical solution, a plurality of limiting plates are provided, and the plurality of limiting plates are symmetrically distributed around the horizontal plate as the center, and the support plate moves away from the limiting plates.

[0012] According to the above technical solution, the surface of the auxiliary block is provided with a cleaning and disinfection device for cleaning and disinfecting the auxiliary block. The cleaning and disinfection device includes a connecting plate two, which is fixedly installed above the auxiliary block. A sliding groove three is opened on the surface of the auxiliary block. A vertical plate is slidably installed on the inner wall of the sliding groove three. A sweeping plate is slidably installed at the bottom of the vertical plate. A groove two is opened on the side of the auxiliary block. A spring piece is slidably installed on the inner wall of the groove two. 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 to the surface of the spring piece. Then, the sweeping plate moves to wipe and disinfect the surface of the spring piece.

[0013] According to the above technical solution, a spring three is provided between the top of the vertical plate and the auxiliary block. The spring three is used to reset the vertical plate. When the vertical plate moves downward, it will drive the bottom sweeping plate to move downward.

[0014] This invention provides a clinical head and neck surgery auxiliary retraction device. It has the following beneficial effects:

[0015] (1) This clinical head and neck surgery auxiliary opening device, when the mounting plate moves away from the range of the slider, the slider will return to the initial state under the action of the spring and limit the mounting plate, so as to adapt to the wound position 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 surrounding tissues, reducing complications, and improving surgical efficiency. This can not only improve the success rate of surgery, but also significantly improve the postoperative recovery process and quality of life of patients.

[0016] (2) This clinical head and neck surgery auxiliary opening device can move downwards by means of a sliding plate without being limited by a baffle, so as to adapt to the size of different patients' necks. At the same time, the adjusting plate can be moved back and forth by adjusting the adjusting rod two, and the clamp can be moved left and right by adjusting the adjusting rod one, so as to achieve the effect of arbitrarily adjusting the position of the wound, making the surgery more precise, safe and comfortable. It can not only improve the doctor's operating efficiency, but also improve the quality of postoperative recovery of patients and extend the service life of the equipment.

[0017] (3) The clinical head and neck surgery auxiliary opening device moves away from the limiting plate by the support 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 connecting plate. When the connecting plate is limited, it will limit the slider. Therefore, it prevents the mounting plate from accidentally touching and moving the slider, so as to ensure that the operation is more stable, safe and precise, which helps to improve the surgical effect and reduce the risk, thereby extending the service life of the equipment, improving the safety of the operation, and avoiding the instability of the equipment due to shaking.

[0018] (4) This clinical head and neck surgery auxiliary retraction device moves downwards via a scanning plate to the surface of a spring clip. The scanning plate then wipes and disinfects the surface of the spring clip. After disinfection, the scanning plate returns to the bottom of the vertical plate manually. Subsequently, the vertical plate returns to its initial state under the action of spring three, thus not affecting subsequent work. This is not only a necessary measure to protect the health and safety of patients, but also extends the service life of the equipment, improves efficiency and safety during surgery, and complies with health regulations. It is fundamental to ensuring the smooth progress of surgery and reducing the risk of infection and complications. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-7 One embodiment of the present invention is: a clinical head and neck surgery auxiliary opening device, comprising a frame 1, a motor 2 fixedly mounted on the top of the frame 1, a threaded rod 3 fixedly mounted on the output end of the motor 2, a horizontal plate 4 slidably mounted on the circumferential surface of the threaded rod 3, an mounting plate 5 fixedly mounted on the top of the horizontal plate 4, a sliding plate 6 slidably mounted on the side of the mounting plate 5, an auxiliary block 7 fixedly mounted on the bottom of the sliding plate 6, and an adjustment device for adjusting the auxiliary block 7 provided on the inner wall of the horizontal plate 4. The adjustment device includes a groove 81, which is formed inside the horizontal plate 4, and a slider 82 slidably mounted inside the groove 81. A connecting plate 82 is fixedly mounted on the bottom of the slider 82. 84. A sliding groove 85 is provided on the side of the mounting plate 5. A baffle 86 is slidably installed on the inner wall of the sliding groove 85. An movable groove 88 is provided on the side of the auxiliary block 7. An adjusting plate 89 is slidably installed on the inner wall of the movable groove 88. A clamp 810 is slidably installed inside the adjusting plate 89. An adjusting rod 811 is fixedly installed on the side of the clamp 810. An adjusting rod 812 is fixedly installed on the side of the adjusting plate 89. The slider 82 will slide towards the inner wall of the groove 81. When the mounting plate 5 leaves the range of the slider 82, the slider 82 will return to the initial state under the action of the spring 83 and limit the mounting plate 5, so as to adapt to the wound position of different patients.

[0029] The side of slider 82 is set as an inclined surface. A spring 83 is provided between the inner wall of groove 81 and slider 82. Spring 83 is used to reset slider 82, and slider 82 will slide towards the inner wall of groove 81.

[0030] The side 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 slide 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 slide groove 85.

[0031] In operation, this embodiment works as follows: When in use, motor 2 is started. The output end of motor 2 rotates, driving the threaded rod 3 to rotate. The rotation of the threaded rod 3 causes the horizontal plate 4 on the surface to slide downwards. The downward sliding of the horizontal plate 4 causes the upper mounting plate 5 to move downwards. The downward movement of the mounting plate 5 causes the sliding plate 6 to move downwards. The downward movement of the sliding plate 6 causes the bottom auxiliary block 7 to move downwards. The downward movement of the auxiliary block 7 contacts the surgical patient's wound. During this process, the mounting plate 5 is manually pushed inwards. The inward movement of the mounting plate 5 contacts the inclined surface of the slider 82. When the slider 82 is compressed, it slides towards the inner wall of the groove 81. When the mounting plate 5 leaves the range of the slider 82, the slider 82 returns to its initial state under the action of the spring 83, limiting the mounting plate 5. This adapts to different wound positions of patients, allowing doctors to adjust according to individual patient needs. To address differences and surgical needs, the system ensures optimal exposure of the surgical area while protecting the integrity of surrounding tissues, reducing complications, and improving surgical efficiency. This not only increases the success rate of the surgery but also significantly improves the patient's postoperative recovery process and quality of life. Subsequently, when patients have different neck sizes, the doctor moves the baffle 86 towards the inner wall of the slide 85. At the same time, the slide plate 6 moves downward without being limited by the baffle 86, thus adapting to different neck sizes. When the wound position is inconsistent, the adjusting rod 812 can be adjusted to move the adjusting plate 89 back and forth, and then the adjusting rod 811 can be adjusted to move the clamp 810 left and right, thereby achieving the function of arbitrarily adjusting the wound position, making the surgery more precise, safe, and comfortable. This not only improves the doctor's operating efficiency but also improves the patient's postoperative recovery quality and extends the service life of the equipment.

[0032] Please see Figures 1-7Based on the above embodiments, in another embodiment of the present invention, a limiting device for limiting the connecting plate 84 is provided on the side of the horizontal plate 4. The limiting device includes a second mounting plate 91, which is fixedly installed on the side of the horizontal plate 4. A limiting plate 92 slides through the interior of the second mounting plate 91. A second sliding groove 93 is provided on the surface of the second mounting plate 91. A support plate 94 is slidably installed on the inner wall of the second sliding groove 93. An installation groove 95 is provided on the side of the second sliding groove 93. A square plate 96 is slidably installed on the inner wall of the installation groove 95. An L-shaped plate 97 is fixedly installed on the top of the square plate 96. When the L-shaped plate 97 moves into the installation groove 95, it will drive 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, the support plate 94 is manually moved away from the limiting plate 92.

[0033] The side of the square plate 96 is set as a slope three. The slope three is used to make the support plate 94 press the slope three of the square plate 96 for limiting. When the support plate 94 moves away from the limiting plate 92, it will leave the range of the limiting plate 92.

[0034] Several limiting plates 92 are provided, and the several limiting plates 92 are symmetrically distributed with the horizontal plate 4 as the center. The support plate 94 moves away from the limiting plates 92.

[0035] The surface of the auxiliary block 7 is provided with a cleaning and disinfection device for cleaning and disinfecting the auxiliary block 7. The cleaning and disinfection device includes a connecting plate 2 101, which is fixedly installed above the auxiliary block 7. The surface of the auxiliary block 7 is provided with a sliding groove 3 102. A vertical plate 103 is slidably installed on the inner wall of the sliding groove 3 102. A sweeping plate 105 is slidably installed at the bottom of the vertical plate 103. A groove 2 106 is provided on the side of the auxiliary block 7. A spring piece 107 is slidably installed on the inner wall of the groove 2 106. 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 to the surface of the spring piece 107. Then, the sweeping plate 105 is moved to wipe and disinfect the surface of the spring piece 107.

[0036] A spring 104 is provided between the vertical plate 103 and the upper part of the auxiliary block 7. The spring 104 is used to reset the vertical plate 103. When the vertical plate 103 moves downward, it will drive the bottom sweeping plate 105 to move downward.

[0037] In this embodiment, when the slider 82 needs to be kept stationary, the L-shaped plate 97 can be manually pulled into the mounting groove 95. The movement of the L-shaped plate 97 into the mounting groove 95 will cause 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, the support plate 94 can be manually moved away from the limiting plate 92. The support plate 94 will then leave the range of the limiting plate 92. Without the support of the support plate 94, the limiting plate 92 will move downwards. This downward movement of the support plate 94 will limit and block the connecting plate 84. When the connecting plate 84 is limited, the slider 82 will also be limited, thus preventing the mounting plate 5 from accidentally moving the slider 82. This ensures a more stable, safe, and precise operation, helps improve surgical results and reduce risks, thereby extending the lifespan of the equipment, improving surgical safety, and avoiding instability caused by shaking.

[0038] Simultaneously, when the bottom of the auxiliary block 7 needs disinfection and cleaning, the vertical plate 103 is manually moved downwards. This downward movement of the vertical plate 103 causes the bottom sweeping plate 105 to move downwards as well. The sweeping plate 105 then moves to the surface of the spring piece 107, where it wipes and disinfects the surface. After disinfection, the sweeping plate 105 returns to the bottom of the vertical plate 103 under manual intervention. Subsequently, the vertical plate 103 returns to its initial state under the action of the spring 104, thus avoiding any impact on subsequent procedures. This is not only a necessary measure to protect patient health and safety but also extends the equipment's lifespan, improves efficiency and safety during surgery, and complies with health regulations. It is fundamental to ensuring smooth surgery and reducing the risk of infection and complications.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
