DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] For example, see Figure 1-Figure 10 The present invention discloses an auxiliary opening device for abdominal surgery, comprising a mounting plate 1, folding components 3 are arranged on both sides of the mounting plate 1, the folding component 3 comprises a folding plate 31 hinged to the mounting plate 1, a torsion spring 32 for providing folding power is arranged at the rotating shaft of the mounting plate 1 and the folding plate 31, a transmission gear 33 is fixedly connected to the rotating shaft of the mounting plate 1 and the folding plate 31, a driving component 2 for providing power is arranged on one side of the mounting plate 1, the driving component 2 comprises a fixed bin 21 fixedly connected to one side of the mounting plate 1, a hydraulic rod 22 is installed in the fixed bin 21, a supporting component 4 for supporting an incision is slidably connected to the mounting plate 1, the supporting component 4 comprises a first supporting structure 41 and a second supporting structure 42, the first supporting structure 41 and the second supporting structure 42 are both slidably connected to the mounting plate 1, and a supporting leg 19 for maintaining the balance of the equipment is fixedly installed below the mounting plate 1.

[0030] The existing abdominal surgery auxiliary expansion device, when supporting the patient's incision, due to the different sizes of incisions and the large amount of fat accumulated in the abdomen, one support plate may not be able to fully expand the fat, especially at the two ends of the incision. The fat accumulated in the incision will occupy the originally limited surgical operation space, making it difficult for the doctor to perform the operation, making it difficult for the doctor to clearly see the structure and details of the surgical site, increasing the difficulty of the operation; the device can have the beneficial effect of freely adjusting the size of the incision support area according to the size of the patient's incision through the cooperation of various structures. At the same time, the device can also fold the folding plates 31 on both sides through the folding component 3 after the operation to reduce the space occupied by the storage of the device. At the same time, when folding, the various support structures can be concentrated in one place to facilitate postoperative disinfection and subsequent sterile storage.

[0031] The mounting plate 1 is used as a basic component to carry other components and structures. At the same time, the design of the folding component 3 can reduce the space occupied by the equipment when it is stored. Through the action of the torsion spring 32, the folding plate 31 can be automatically folded, providing flexible adjustment space for the equipment for easy operation; the hydraulic rod 22 is used as a power source to provide a stable and adjustable driving force to ensure that the support component 4 or other components requiring power can move accurately and reliably; the first support structure 41 and the second support structure 42 are connected to the mounting plate 1 through a sliding connection, and the support position can be adjusted by the hydraulic rod 22 as needed to provide stable support for the support plate of the support cutout; the support leg 19 is located under the equipment, which can ensure that the equipment remains balanced during operation and avoid safety problems caused by unstable center of gravity of the equipment.

[0032] Example 2: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 10A pair of first slide grooves 11, second slide grooves 12, and folding slide grooves 17 are sequentially opened on one side of the mounting plate 1. The first slide groove 11 is connected to the first vertical groove 13, and the second slide groove 12 is connected to the second vertical groove 14. A first inclined groove 15 is provided on one side of the first slide groove 11, a second inclined groove 16 is provided on one side of the second slide groove 12, and a folding inclined groove 18 is provided on one side of the folding slide groove 17. The first inclined groove 15, the second inclined groove 16, and the folding inclined groove 18 are all opened on the mounting plate 1, and a power rack 110 is provided in the first slide groove 11 and the second slide groove 12.

[0033] A part of the folding slide groove 17 and the folding inclined groove 18 is opened on the folding plate 31 .

[0034] The power output end of the hydraulic rod 22 is fixedly connected to a driving slide rail 23 , and the interior of the driving slide rail 23 is slidably connected to a sliding track 24 . An elastic spring 25 is provided at one end of the sliding track 24 , and the elastic spring 25 is located inside the driving slide rail 23 .

[0035] A sliding groove 37 is provided on the other side of the mounting plate 1, and a resistance block 35 is slidably connected to one side of the sliding groove 37. The resistance block 35 is provided with a resistance inclined surface 36, and the resistance inclined surface 36 is used to resist the driving slide rail 23. The resistance block 35 is located on one side of the sliding rail 24, and a transmission rack 34 is provided on one side of the resistance block 35, and the transmission rack 34 is used to mesh with the transmission gear 33.

[0036] The device drives the driving rail 23 through the hydraulic rod 22, so that the driving rail 23 can slide downward. When the driving rail 23 slides downward, the driving rail 23 contacts the contact inclined surface 36 on the contact block 35. The contact with the contact inclined surface 36 makes the contact block 35 slide in the sliding groove 37. The design of the sliding groove 37 makes the sliding of the contact block 35 more stable, and prevents the contact block 35 from deviating, providing necessary support for the sliding of the contact block 35. When the contact block 35 slides, it drives the transmission rack 34 to slide together. The sliding of the transmission rack 34 makes the transmission gear 33 meshing with the transmission rack 34 rotate. The rotation of the transmission rack 34 drives the rotating shaft to rotate, so that the rotating shaft at the hinge of the folding plate 31 and the mounting plate 1 rotates. The folding plate 31 is unfolded by the rotation of the rotating shaft. When the folding plate 31 is unfolded, the torsion spring 32 is deformed. The design of the torsion spring 32 makes the hydraulic rod 22 When the driving slide rail 23 slides upward, it can provide power for the automatic folding of the folding plate 31; when the driving slide rail 23 slides over the interfering inclined surface 36, it will interfere with one side of the interfering block 35, and at this time the folding plate 31 has been fully unfolded. Through such a design, the position of the interfering block 35 can be limited, so that the interfering block 35 will not slide, and at the same time, the position of the transmission rack 34 can be fixed, so that the transmission rack 34 can lock the position of the transmission gear 33, preventing the transmission gear 33 from rotating under the action of the torsion spring 32, so that the state of the folding plate 31 can be stable, and at the same time, it will not affect the continued downward sliding of the driving slide rail 23; the interfering block 35 is on one side of the sliding rail 24, and the position of the interfering block 35 will not affect the sliding of the sliding rail 24; after the folding plate 31 is unfolded, the folding slide groove 17, the folding inclined groove 18 and the folding slide groove 17 and the folding inclined groove 18 on the mounting plate 1 can be connected to form a complete slide groove, providing the necessary conditions for subsequent normal operation.

[0037] Example 3: This example is an explanation based on Example 1. For details, please refer to Figure 1-Figure 10 The first supporting structure 41 includes a sliding block 43 slidably connected to the first sliding groove 11 and the first vertical groove 13. A sliding rod 44 is fixedly connected to one side of the sliding block 43. A sliding bin 45 is slidably connected to one side of the sliding rod 44. A spring 46 is installed inside the sliding bin 45. The spring 46 abuts against one end of the sliding rod 44. One side of the sliding bin 45 is slidably connected to the first inclined groove 15.

[0038] One side of the sliding block 43 is rotatably connected to a power gear 47, which is meshed with the power rack 110. One side of the power gear 47 is fixedly connected to a square rod 48. The interior of the sliding block 43 is threadedly connected to a screw rod 49, and a square groove 414 is provided in the middle of the screw rod 49. The square rod 48 is slidably connected to the square groove 414.

[0039] One end of the screw rod 49 is rotatably connected to a support plate 410, a limit rod 411 is provided on one side of the support plate 410, the limit rod 411 is slidably connected to one end of the sliding bin 45, a mounting block 412 is provided on one side of the support plate 410, the mounting block 412 is used to install a support sheet supporting the incision, a third slide groove 415 is opened on one side of the support plate 410, and the third slide groove 415 is slidably connected to the screw rod 49.

[0040] The folding slide groove 17 and the folding inclined groove 18 are slidably connected with a support block 413, and a mounting block 412 for mounting a support sheet is also mounted on the support block 413. The first support structure 41 and the second support structure 42 adopt the same structural design.

[0041] When the driving rail 23 slides downward, the sliding column on one side of the power gear 47 will be driven to slide together. The sliding column is located in the driving rail 23. The driving rail 23 slides downward so that the sliding column drives the power gear 47 and the sliding block 43 to slide in the first slide groove 11. At the same time, the sliding of the sliding block 43 drives the sliding bin 45 to slide in the first inclined groove 15 through the sliding rod 44. When the sliding bin 45 slides to one end of the first inclined groove 15, the sliding column on the sliding block 43 just slides into the first vertical groove 13. As the driving rail 23 continues to slide, the sliding column slides with the sliding block 43 into the first vertical groove 13. The sliding in the first inclined groove 15 enables the sliding block 43 to slide downward, and at the same time enables the sliding rod 44 to slide into the sliding bin 45, so that the sliding rod 44 resists the spring 46, causing the spring 46 to deform, thereby providing power for the resetting of the postoperative device; through the simultaneous design of the first sliding groove 11 and the first inclined groove 15, the sliding column on the sliding block 43 slides in the driving slide rail 23 and the sliding bin 45 slides in the first inclined groove 15, and when the power gear 47 slides in the first sliding groove 11, the power gear 47 meshes with the power rack 110 to rotate, so that the sliding of the sliding block 43 and the sliding bin 45 is more stable, and the deviation is prevented;

[0042] When the power gear 47 slides in the first slide groove 11, it meshes with the power rack 110 in the first slide groove 11. The meshing with the power rack 110 makes the power gear 47 rotate, and the rotation of the power gear 47 makes the square rod 48 rotate together. When the square rod 48 rotates, the square rod 48 drives the screw rod 49 to rotate together. At the same time, the design of the square groove 414 in the screw rod 49 makes it possible to drive the screw rod 49 to rotate together when the square rod 48 rotates; when the screw rod 49 rotates, the screw rod 49 rotates in the wire groove of the sliding block 43, and when it rotates, the screw rod 49 slides outward from the sliding block 43, and the screw rod 49 will not be separated from the square rod 48; when the screw rod 49 slides outward, it drives the support plate 410 to move together, and at the same time, the limit rod 411 and the sliding bin 4 5 slides, so that the limiting rod 411 slides out of the sliding compartment 45, and the limiting rod 411 will not be separated from the sliding compartment 45. Through such a design, the screw rod 49 will not drive the support plate 410 to rotate when it rotates to slide out of the sliding block 43, so that the sliding of the support plate 410 can be more stable, so that the mounting block 412 can be stable, so that the support sheet can slide stably when supporting the incision of the patient, and prevent it from touching the part other than the incision of the patient; at the same time, when the sliding rod 44 slides into the sliding compartment 45, the screw rod 49 will slide in the third sliding groove 415 of the support plate 410, and when the screw rod 49 rotates and slides in the support plate 410, the screw rod 49 will not be separated from the support plate 410. Through such a design, each support sheet can stably support the incision.

[0043] The sliding column on one side of the support block 413 is located in the sliding track 24. When the sliding track 24 slides downward with the driving slide rail 23, the sliding bin 45 is driven to slide along the folding slide groove 17 and the folding inclined groove 18. With the continuous sliding, the support block 413 gradually slides toward the end of the folding plate 31, so that the sliding track 24 is driven to retract and extend through the sliding column of the support block 413, so that the sliding track 24 is extended. When the sliding track 24 slides, the elastic spring 25 inside the driving slide rail 23 is deformed. The design of the elastic spring 25 provides power for the subsequent reset of the sliding track 24. At the same time, the design of the driving slide rail 23 and the sliding track 24 enables the subsequent folding plate 31 to be folded normally. At the same time, the design of the folding slide groove 17 and the folding inclined groove 18 does not affect the folding of the folding plate 31, while the support block 413 can operate normally. The folding slide groove 17, The design of the folding inclined groove 18 can also prevent the sliding column of the support block 413 from causing the support block 413 to deviate when the sliding column slides in the sliding track 24, so that the sliding of the support block 413 can be more stable; through the design of multiple mounting blocks 412, when the patient's incision is large, the driving slide rail 23 can be pressed down by the hydraulic rod 22, so that the first support structure 41, the second support structure 42, and the support plates on the support block 413 support the incision in turn, and when the driving slide rail 23 is pressed down to the bottom, the support plates on each support structure are on the same horizontal line. At the same time, when each mounting block 412 is on the same horizontal line, the mounting block 412 in the middle of the mounting plate 1 is farther away from the mounting plate 1, and the mounting blocks 412 at both ends of the mounting plate 1 are closer to the mounting plate 1, thereby preventing the support plates on the mounting block 412 from tearing the two ends of the patient's incision.

[0044] The length of the first slide groove 11 is smaller than the second slide groove 12, the length of the second slide groove 12 is smaller than the folding slide groove 17, the length of the first inclined groove 15 is smaller than the second inclined groove 16, the length of the second inclined groove 16 is smaller than the folding inclined groove 18, and the length of the first vertical groove 13 is larger than the second vertical groove 14. Through such a design, after the first supporting structure 41 is in the working position, if the incision is large, the driving slide rail 23 can be continued to drive the sliding block 43 on the second supporting structure 42 to continue to slide, so that the support plate 410, the mounting block 412, and the support sheet on the second supporting structure 42 slide to the supporting position. If the entire incision still cannot be supported, the driving slide rail 23 and the sliding rail 24 can be continuously driven by the hydraulic rod 22, so that the support block 413 drives the mounting block 412 and the support sheet to continue to support the incision; through such a design, medical staff can more flexibly adjust the equipment according to the size of the patient's incision;

[0045] The device has three stages. When the patient's incision is small, the hydraulic rod 22 presses down the driving slide rail 23, so that the support plate on the first support structure 41 supports the incision. At this time, the second support structure 42 and the support block 413 will not contact the patient's incision; when the patient's incision is large, the hydraulic rod 22 will continue to press down the driving slide rail 23, so that the support plate on the second support structure 42 supports the incision. At this time, the first support structure 41 and the second support structure 42 are on the same horizontal line, and the support block 413 will not contact the patient; if the patient's incision is larger, the hydraulic rod 22 will continue to press down the driving slide rail 23, so that the support plate on the support block 413 supports the patient's incision. At this time, the first support structure 41, the second support structure 42, and the support block 413 are on the same horizontal line, so as to provide stable support for the patient's incision.

[0046] When use is over, the hydraulic rod 22 drives the driving slide rail 23 and the sliding rail 24 to slide upward, and the upward sliding of the driving slide rail 23 and the sliding rail 24 drives each sliding column to slide together, and at the same time, the power gear 47 rotates in the opposite direction, so that the screw rod 49 is retracted into the sliding block 43, and at the same time, the support plate 410, the mounting block 412, and the support sheet move together; when the driving slide rail 23 slides to the conflict with the interference slope 36, under the action of the torsion spring 32, the folding plate 31 begins to fold, and at the same time, the transmission gear 33 rotates in the opposite direction, driving the transmission rack 34 and the interference block 35 to slide back together, and as the driving slide rail 23 continues to shrink, the driving slide rail 23 no longer conflicts with the interference slope 36, so that the folding plate 31 is folded, and before the folding plate 31 is folded, each support sheet has left the patient's incision.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] 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 technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
