Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary beds, and in particular relates to an auxiliary frame for ophthalmic hunchback surgery. Background Art

[0002] During ophthalmic surgery, patients are generally required to lie on the operating table in a semi-recumbent position to relieve eye pressure, reduce blood reflux in the head, and facilitate the discharge of blood and fluid. It is particularly important for patients who need to control intraocular pressure to adopt a semi-recumbent position. However, the backrests of existing ophthalmic operating tables are basically flat and can only be adjusted in pitch as a whole. Therefore, when patients with hunchbacks undergo surgery, the ordinary backrests have poor wrapping properties for their backs. Except for the protruding part of their back that contacts the backrest, the other parts are basically in a suspended state and are difficult to fit with the backrest. Therefore, the support and wrapping properties for their backs are very poor, making it difficult to ensure that the patient leans stably on the backrest. Once shaking occurs during the operation, it is easy to cause dangerous situations. For this reason, we propose an ophthalmic surgical auxiliary frame for patients with hunchbacks. Utility Model Content

[0003] In response to the above problems, the purpose of the present utility model is to provide an ophthalmic surgical auxiliary frame for hunchback patients. The device has rich adjustment functions and a certain linkage adjustment structure. It can adjust the height of the armrests and has an outer bottom plate and an inner bottom plate that can fit the curved shape of the patient's legs. While facilitating overall adjustment and installation, it ensures the patient's lying comfort during surgery. Through the design of four sets of freely adjustable backboards, it can improve the wrapping and support stability of the patient's back, especially the back of a hunchbacked patient, thereby improving the stability of the operation and reducing the surgical risks caused by the inability of the operating table to firmly support and wrap the patient's back due to the patient's hunchback.

[0004] To achieve the above purpose, the utility model provides the following technical solutions: an ophthalmic hunchback patient surgical auxiliary frame, comprising a left guide rail frame and a right guide rail frame, wherein a keel is connected between the left guide rail frame and the right guide rail frame, and a left slide rail and a right slide rail are respectively slidably provided on the left side of the left guide rail frame and the right side of the right guide rail frame, and a transmission inner tooth groove is provided on the left side of the left slide rail and the right side of the right slide rail, and an operating table clamping device is provided at the front end and the rear end of the left guide rail frame and the right guide rail frame. The right side of the left slide rail and the left side of the right slide rail are jointly installed with a rotatable base plate mechanism, and the left side of the left guide rail frame and the right side of the right guide rail frame are rotatably connected to the slide rod fixing seat, the inner side of the slide rod fixing seat is inserted and installed with a slide rod, the outer side of the slide rod is connected to the armrest movable adjustment component, the outer side of the slide rod is provided with four groups of backboard movable adjustment components, namely upper left, lower left, upper right and lower right, one end of the slide rod is connected to the fixed suspension block, the inner side of the fixed suspension block is inserted and installed with a headrest suspension, and the outer side of the headrest suspension is provided with an adjustable headrest.

[0005] The beneficial effects of the present invention are as follows: the device has rich adjustment functions and a certain linkage adjustment structure, which can adjust the height of the armrests and has an outer bottom plate and an inner bottom plate that can fit the curved shape of the patient's legs. While facilitating overall adjustment and installation, it ensures the patient's lying comfort during surgery. Through the design of four sets of freely adjustable backboards, the wrapping and support stability of the patient's back, especially the back of a hunchbacked patient, can be improved, thereby improving the stability of the operation and reducing the surgical risks caused by the inability of the operating table to firmly support and wrap the patient's back due to the patient's hunchback.

[0006] To adjust the armrests and backrest:

[0007] The top of the armrest is provided with an armrest, and the side of the armrest is rotatably mounted on the side of the armrest.

[0008] The beneficial effect of this improvement is that when adjusting the up and down tilt angle of the backboard, the sliding bar is rotated upward so that the backboard can adjust the pitch angle accordingly. Since the sliding bar, the left slide rail, the armrest bar, the linkage bar and the sliding bar, the armrest bar and the linkage bar all form a parallelogram shape, when the sliding bar rotates, the armrest bar and the linkage bar will also move accordingly, so that the armrest is lifted and maintained in a horizontal state. Due to the provision of the sliding groove, the fixing latch, the spring and the non-return ratchet, when the sliding bar and the armrest bar rotate relative to each other as the sliding bar rotates upward, the ratchet at one end of the armrest bar rotates accordingly and drives the fixing latch to slide along the sliding groove through the non-return ratchet. Due to the provision of the spring, the fixing latch can automatically rebound, so that the non-return ratchet fits into the ratchet teeth of the ratchet wheel to prevent the ratchet wheel from rotating, thereby limiting the sliding bar and preventing it from automatically lowering, thereby playing a supporting role for the sliding bar and the backboard.

[0009] To secure the device to the operating table:

[0010] As a further improvement of the above technical solution: the operating table clamping device includes a telescopic rod slide arranged at the front and rear ends of the left guide rail frame and the right guide rail frame, a telescopic rod is slidably installed on the inner side of the telescopic rod slide, a telescopic rod locking bolt passes through and is threadedly connected between the side surface of the telescopic rod slide and the inner side of the telescopic rod slide, one end of the telescopic rod is connected to a long fixed foot collar, a long fixed foot is slidably inserted into the inner side of the long fixed foot collar, a short fixed foot is sleeved on the outer side of the long fixed foot, and a fixed foot locking bolt passes through and is threadedly connected between the inner and outer sides of the short fixed foot and between the inner and outer sides of the long fixed foot collar.

[0011] The beneficial effect of this improvement is: the device is placed as a whole on the top of the operating table, and the extension length of the telescopic rod is adjusted by loosening the telescopic rod locking bolt and the fixed leg locking bolt, and the telescopic rod is rotated and the positions of the long fixed legs and the short fixed legs are adjusted to be able to clamp the two side edges of the operating table.

[0012] For air circulation and to further seal the power module:

[0013] As a further improvement of the above technical solution: the rotatable bottom plate mechanism includes bottom plate fixing blocks rotatably provided on the right side of the left guide rail frame and the left side of the right guide rail frame, the right side of the left slide rail and the left side of the right slide rail, the top of the bottom plate fixing blocks on the left guide rail frame and the right guide rail frame are connected to the inner bottom plate, the top of the bottom plate fixing blocks on the left slide rail and the right slide rail are connected to the outer bottom plate, and the outer bottom plate and the inner bottom plate are connected by a hinge.

[0014] The beneficial effect of this improvement is that when the linkage rod rotates upward, while supporting the other end of the handrail rod, it also drives the gear to rotate, so that transmission is transmitted between the gear and the inner tooth groove of the transmission, thereby driving the left slide rail and the right slide rail to move toward the slide rod, so that the bottom plate fixing blocks on the left slide rail and the right slide rail and the bottom plate fixing blocks on the left guide rail frame and the right guide rail frame are close to each other, thereby driving the outer bottom plate and the inner bottom plate to fold and rotate through the hinge, so that the outer bottom plate and the inner bottom plate can fit the curved shape of the patient's legs.

[0015] To adjust the backrest to better support the patient's back and accommodate hunchback:

[0016] The cam is secured to the outside of the adjustment mechanism and is adapted to engage the driver of the adjustment mechanism, wherein the cam is secured on the outside of the adjustment mechanism and is adapted to engage the driver of the adjustment mechanism.

[0017] The beneficial effect of this improvement is that when the position of the backboard and the angle relative to the slide bar need to be adjusted, rotating the slide bar fixing wheel can drive the fixing seat locking screw to rotate, and loosening the fixing seat locking screw can adjust the position of the fixing seat on the slide bar and rotate the fixing seat. When the backboard needs to be rotated, first loosen the backboard fixing wheel tightened on the outer side of the external thread of the adjusting rod, and then rotate the backboard adjusting wheel to drive the rotating shaft to rotate, thereby driving the backboard mounting screw together with the backboard to rotate. After the adjustment is completed, tighten the backboard fixing wheel again, and fix the backboard adjusting wheel through the friction force between the backboard fixing wheel and the backboard adjusting wheel, thereby fixing the backboard. By rotating the backboard adjusting wheel and the fixing seat, the four backboards can be adjusted to an overall concave shape, thereby improving the wrapping and support stability of the patient's back and adapting to the patient's hunchback condition.

[0043] This device has rich adjustment functions and a certain linkage adjustment structure. It can adjust the height of the armrests and has an outer bottom plate 15 and an inner bottom plate 16 that can fit the curved shape of the patient's legs. While facilitating overall adjustment and installation, it ensures the patient's lying comfort during surgery. Through the design of four sets of freely adjustable backboards 44, it can improve the wrapping and support stability of the patient's back, especially the back of a hunchback patient, thereby improving the stability of the operation and reducing the surgical risks caused by the patient's hunchback causing the operating table to be unable to firmly support and wrap the patient's back.

[0044] The armrest movable adjustment assembly 20 includes a slide seat 21 slidably sleeved on the outside of the slide rod 18, a slide seat fixing bolt 22 is passed through and threadedly installed between the inner and outer sides of the slide seat 21, a slide groove 23 is provided on the inner side of the slide seat 21, a fixing tenon 24 is slidably installed on the inner side of the slide groove 23, a spring 25 is provided inside the slide groove 23, a non-return ratchet 26 is provided inside the fixing tenon 24, a cover plate 27 is screwed on one side of the slide seat 21, and a support shaft 28 is fixed inside the slide seat 21. A ratchet 29 is sleeved on the outer side of the support shaft 28, and one side of the ratchet 29 is fixedly connected to a handrail rod 30. The handrail rod 30 and the support shaft 28 are prevented from falling off by a limit bolt. A handrail 31 is provided on the top of the handrail rod 30, and a linkage rod 32 is rotatably installed on the side of one side of the handrail rod 30. The other end of the linkage rod 32 is connected to a gear 33, and the gear 33 is rotatably connected to the left guide rail frame 1 and the right guide rail frame 2, and the gear 33 is engaged with the tooth groove in the transmission inner tooth groove 6.

[0045] When adjusting the up and down tilt angle of the back plate 44, the slide bar 18 is rotated upward to adjust the pitch angle of the back plate 44 accordingly. Since the slide bar 18, the left guide rail frame 1, the handrail bar 30, the linkage bar 32 and the slide bar 18, the right guide rail frame 2, the handrail bar 30, and the linkage bar 32 form a parallelogram shape, when the slide bar 18 is rotated, the handrail bar 30 and the linkage bar 32 will also move accordingly, so that the handrail 31 is lifted and kept in a horizontal state. Due to the provision of the slide groove 23, the fixing tenon 24, the spring 2 5. The non-return ratchet 26. When the slide bar 18 and the handrail bar 30 rotate relative to each other as the slide bar 18 rotates upward, the ratchet 29 at one end of the handrail bar 30 rotates accordingly, and the non-return ratchet 26 drives the fixed tenon 24 to slide along the slide groove. Since a spring 25 is provided, the fixed tenon 24 can automatically rebound, so that the non-return ratchet 26 fits with the ratchet teeth of the ratchet 29 to prevent the ratchet 29 from rotating, thereby limiting the slide bar 18 and preventing it from automatically lowering, thereby supporting the slide bar 18 together with the back plate 44.

[0046] The operating table clamping device includes a telescopic rod slide 7 arranged at the front and rear ends of the left guide rail frame 1 and the right guide rail frame 2. A telescopic rod 8 is slidably installed on the inner side of the telescopic rod slide 7. A telescopic rod locking bolt 9 is passed through and threaded between the side surface of the telescopic rod slide 7 and the inner side of the telescopic rod slide 7. One end of the telescopic rod 8 is connected to a long fixed foot collar 10. A long fixed foot 11 is slidably inserted into the inner side of the long fixed foot collar 10.

[0047] Place the entire device on the top of the operating table, and adjust the extension length of the telescopic rod 8 by loosening the telescopic rod locking bolt 9 and the fixed leg locking bolt 13. Rotate the telescopic rod 8 and adjust the positions of the long fixed legs 11 and the short fixed legs 12 until they can clamp the two side edges of the operating table.

[0048] The rotatable bottom plate mechanism includes bottom plate fixing blocks 14 rotatably provided on the right side of the left guide rail frame 1 and the left side of the right guide rail frame 2, the right side of the left slide rail 4 and the left side of the right slide rail 5. The tops of the bottom plate fixing blocks 14 on the left guide rail frame 1 and the right guide rail frame 2 are connected to the inner bottom plate 16, and the tops of the bottom plate fixing blocks 14 on the left slide rail 4 and the right slide rail 5 are connected to the outer bottom plate 15. The outer bottom plate 15 and the inner bottom plate 16 are connected by a hinge 59.

[0049] When the linkage rod 32 rotates upward, while supporting the other end of the armrest rod 30, it also drives the gear 33 to rotate, so that transmission is transmitted between the gear 33 and the transmission inner tooth groove 6, thereby driving the left slide rail 4 and the right slide rail 5 to move toward the slide rod 18, so that the bottom plate fixing blocks 14 on the left slide rail 4 and the right slide rail 5 and the bottom plate fixing blocks 14 on the left guide rail frame 1 and the right guide rail frame 2 are close to each other, thereby driving the outer bottom plate 15 and the inner bottom plate 16 to fold and rotate through the hinge 59, so that the outer bottom plate 15 and the inner bottom plate 16 can fit the bent shape of the patient's legs.

[0050] The back plate movable adjustment assembly 34 includes a fixing seat 35 which is sleeved on the outside of the sliding rod 18, and an adjusting rod 36 is installed on one side of the fixing seat 35. The outer side of the adjusting rod 36 is provided with an external thread 37, and the inner side of the non-return ratchet 26 is provided with an internal threaded hole 38. The outer side of the adjusting rod 36 is threadedly connected to the back plate fixing wheel 39 through the external thread 37, and the internal threaded hole 38 passes through the inner side of the fixing seat 35, and the inner side of the fixing seat 35 is threadedly connected to the fixing seat locking screw 41. One end of the fixing seat locking screw 41 is connected to the sliding rod fixing wheel 40.

[0051] The back plate 44 is fixed by the friction force between the back plate fixing wheel 39 and the back plate adjusting wheel 46, thereby fixing the back plate 44. By rotating the back plate adjusting wheel 46 and the fixing seat 35, the four back plates 44 can be adjusted to the overall concave shape, thereby improving the wrapping and support stability of the patient's back and adapting to the patient's hunchback condition.

[0052] The adjustable headrest includes a headrest mounting collar 51 which is sleeved on the outside of the headrest suspension 49, a recovery arm 52 is provided on the back of the headrest mounting collar 51, an extension arm 53 is inserted into the inner side of the recovery arm 52, an extension arm locking bolt 54 is passed through and threadedly installed between the inner and outer sides of the recovery arm 52, a collar locking bolt 55 is passed through and threadedly installed between the inner and outer sides of the headrest mounting collar 51, a headrest 56 is provided on the inner side of the top of the extension arm 53, and the extension arm 53 and the headrest 56 are fixed by a headrest fixing bolt 57 and a nut 58.

[0053] When adjusting the headrest 56, loosen the collar locking bolt 55, then slide the headrest mounting collar 51 on the headrest suspension 49 to adjust the left and right positions of the headrest 56, and rotate the headrest mounting collar 51 to adjust the pitch angle of the extension arm 53 and the extension arm locking bolt 54. Loosen the extension arm locking bolt 54 to adjust the extension length of the extension arm 53, and then adjust the height of the headrest 56. Loosen the headrest fixing bolt 57 to rotate the headrest 56 and adjust the angle between it and the extension arm 53. The rich adjustment functions of the headrest 56 can effectively meet the head and neck support needs of patients of different body shapes.

[0054] A slide bar fixing bolt 19 passes through and is threadedly installed between the inner side and the outer side of the slide bar fixing seat 17 , and a suspension fixing bolt 50 passes through and is threadedly installed between the inner side and the outer side of the fixed suspension block 48 .

[0055] The slide rod fixing bolt 19 is used to lock the slide rod 18 , and the suspension fixing bolt 50 is used to lock the headrest suspension 49 .

[0056] The working principle and use process of the present invention are as follows: When the device is used, the device is placed as a whole on the top of the operating table, and the extension length of the telescopic rod 8 is adjusted by loosening the telescopic rod locking bolt 9 and the fixed foot locking bolt 13, and the telescopic rod 8 is rotated and the positions of the long fixed foot 11 and the short fixed foot 12 are adjusted. After the positions of the long fixed foot 11 and the short fixed foot 12 are adjusted to be able to clamp the edge positions of both sides of the operating table, the telescopic rod locking bolt 9 and the fixed foot locking bolt 13 can be re-tightened to fix the device on the operating table, and then the position and direction of the four backboards 44 can be adjusted to fit the patient's back. When adjusting the angle of the backboard 44, the armrest movable adjustment component 20 and the outer bottom plate can be driven 15, the inner bottom plate 16 is adjusted synchronously, and the armrest movable adjustment component 20 is adjusted to facilitate the patient to place his arms. By adjusting the position and angle of the outer bottom plate 15 and the inner bottom plate 16, the patient's bent legs are fitted to enable the patient to adopt a more natural lying posture. In conjunction with the adjustment function of the headrest 56, while being able to adapt to patients of different body shapes, the patient's comfort can be improved. When adjusting the up and down tilt angles of the back plate 44, the slide bar 18 is rotated upward to adjust the pitch angle of the back plate 44 accordingly. Since the slide bar 18, the left slide rail 4, the armrest bar 30, and the linkage bar 32 form a parallelogram shape, when the slide bar 18 rotates, the armrest bar 30 and the linkage bar The armrest 31 is lifted and kept in a horizontal state. Due to the arrangement of the slide groove 23, the fixing latch 24, the spring 25 and the non-return ratchet 26, when the slide bar 18 and the armrest bar 30 rotate relative to each other as the slide bar 18 rotates upward, the ratchet 29 at one end of the armrest bar 30 rotates accordingly and drives the fixing latch 24 to slide along the slide groove through the non-return ratchet 26. Due to the arrangement of the spring 25, the fixing latch 24 can automatically rebound, so that the non-return ratchet 26 fits with the ratchet teeth of the ratchet 29, preventing the ratchet 29 from rotating, thereby limiting the slide bar 18 and preventing it from automatically lowering, thereby supporting the slide bar 18 together with the backboard 44, so that the patient can lean back against the backboard 44 for surgery, and in this process, The armrest bar 30 is not only lifted as the slide bar 18 rotates upward, but also pulls the linkage bar 32 to rotate upward at the same angle as the slide bar 18, while supporting the other end of the armrest bar 30, it also drives the gear 33 to rotate, so that the gear 33 and the transmission inner tooth groove 6 transmit the transmission, thereby driving the left slide rail 4 and the right slide rail 5 to move toward the direction of the slide bar 18, so that the bottom plate fixing blocks 14 on the left slide rail 4 and the right slide rail 5 are close to the bottom plate fixing blocks 14 on the left guide frame 1 and the right guide frame 2, thereby driving the outer bottom plate 15 and the inner bottom plate 16 to fold and rotate through the hinge 59, so that the outer bottom plate 15 and the inner bottom plate 16 can fit the bent shape of the patient's legs. When the slide bar 18 needs to be lowered, the fixing latch 24 is pressed downward.When the non-return ratchet 26 is disengaged from the limit of the ratchet wheel 29, the slide bar 18 can be lowered. Under the aforementioned linkage action, the handrail rod 30, the handrail 31, the linkage rod 32, the left slide rail 4, the right slide rail 5, the outer bottom plate 15, and the inner bottom plate 16 are also restored to their original positions. When it is necessary to adjust the position of the back plate 44 and the angle relative to the slide bar 18, the slide bar fixing wheel 40 can be rotated to drive the fixing seat locking screw 41 to rotate. The fixing seat locking screw 41 can be loosened to adjust the position of the fixing seat 35 on the slide bar 18 and the fixing seat 35 can be rotated. When it is necessary to rotate the back plate 44, the back plate fixing wheel 39 that is tightened on the outside of the external thread 37 of the adjusting rod 36 is first loosened. Then, by rotating the back panel adjusting wheel 46, the rotating shaft 42 can be driven to rotate, thereby driving the back panel mounting screw 43 to rotate together with the back panel 44. After the adjustment is completed, the back panel fixing wheel 39 is tightened again, and the friction between the back panel fixing wheel 39 and the back panel adjusting wheel 46 is used to fix the back panel adjusting wheel 46, thereby fixing the back panel 44. By rotating the back panel adjusting wheel 46 and the fixing seat 35, the four back panels 44 can be adjusted to an overall concave shape, thereby improving the wrapping and support stability of the patient's back and adapting to the patient's hunchback condition. When adjusting the headrest 56, loosen the collar locking bolt 55, and slide the headrest mounting collar 51 on the headrest suspension 49 to adjust the headrest 56. The left and right positions of the headrest can be adjusted, and the pitch angle of the extension arm 53 and the extension arm locking bolt 54 can be adjusted by rotating the headrest mounting collar 51. By loosening the extension arm locking bolt 54, the extended length of the extension arm 53 and the height of the headrest 56 can be adjusted. By loosening the headrest fixing bolt 57, the headrest 56 can be rotated to adjust the angle between it and the extension arm 53. The rich adjustment functions of the headrest 56 can effectively meet the head and neck support needs of patients of different body shapes and facilitate the adjustment of the patient's head posture. After using the device, the long fixing legs 11 and the short fixing legs 12 can be released from the operating table, and then the device can be moved away from the operating table as a whole. The installation and removal functions allow the device to be freely used or not according to the needs of the actual use scenario. In summary, the device has a variety of adjustment functions and a certain linkage adjustment structure. It can adjust the height of the armrests and has an outer bottom plate 15 and an inner bottom plate 16 that can fit the curved shape of the patient's legs. While facilitating overall adjustment and installation, it also ensures the patient's lying comfort during surgery. The design of four sets of freely adjustable back plates 44 can improve the wrapping and support stability of the patient's back, especially the back of patients with hunchbacks, thereby improving surgical stability and reducing surgical risks caused by the patient's hunchback causing the operating table to be unable to firmly support and wrap the patient's back.
