[0039] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0040] See also Figures 1-6 , an adjustable thoracotomy for general thoracic surgery, comprising:

[0041] The device body 1 includes a fixed horizontal plate 10, a fixed vertical plate 11 and a movable plate 12. The fixed horizontal plate 10 is provided with a groove 101 in the middle position. The groove 101 is provided with a partition 1012 that divides it into an upper groove 1010 and a lower groove 1011. The partition 1012 is provided with a strip-shaped through hole 10120, and the inner side of the left end is provided with an accommodating cavity 103 that runs through the upper groove 1010. The fixed vertical plate 11 is fixedly connected to one end of the fixed horizontal plate 10, and the movable plate 12 is movably connected to the fixed horizontal plate 10;

[0042] A pushing component 2, wherein the pushing component 2 is movably connected to the accommodating cavity 103;

[0043] a tensioning assembly 3 movably connected to the right end of the fixed horizontal plate 10 , and movably connected to the movable plate 12 ;

[0044] The pusher claw assembly 4 is provided with two groups, which are movably connected to the fixed longitudinal plate 11 and the movable plate 12 respectively.

[0045] During use, the fixed claw 40 and the adjusting claw 41 on the fixed horizontal plate 10 and the movable vertical plate 11 are placed into the patient's incision, and then the adjusting handle 420 is lifted upward, driving the rectangular rod 421 to disengage from the rotating rod 423. Due to the rotational connection between the rotating rod 423 and the fixed sleeve 422, during the subsequent surgical process, the adjusting claw 41 fixedly connected to the rotating rod 423 will rotate its own angle as it contacts the skin at the incision to fit the incision.

[0046] First, the medical staff takes out the positioning column 10111, and then connects the positioning column 10111 to the positioning groove 10110 according to the scale thread based on their own experience or the actual needs of the patient. After putting the claw assembly 4 into the incision, the medical staff can inflate the strip airbag 20 by squeezing the air pump 22, so that the strip airbag 20 gradually expands until it can no longer be inflated. During the expansion process, it will first push the end of the movable longitudinal plate 110 located on the inner side of the fixed transverse plate 10 to move. When this side of the movable longitudinal plate 110 moves with the expansion of the strip airbag 20, the cylindrical shaft 121 fixedly connected to the movable longitudinal plate 110 also moves accordingly, and during its movement, it drives the end thereof. The meshing toothed belt 31 rotates, and the rotation of the toothed belt 31 drives the rotation of the tensioning shaft 30. As the tensioning shaft 30 rotates, the actual use length of the tensioning wire 32 wound on the tensioning shaft 30 gradually shortens, and the movable longitudinal plate 120 fixedly connected to the other end is pulled over, so that when the movable longitudinal plate 120 opens the patient's incision, the lower end always moves a little, and then the upper end moves a little more, but the difference in the distance moved by the upper and lower ends is small, so that the upper and lower ends are guaranteed to open the patient's incision at a uniform speed. When the strip airbag 20 can no longer be inflated, it means that the movable longitudinal plate 120 has been pushed to the scale 1013 positioned in advance by the positioning column 10111;

[0047] During the spreading process, the part of the skin at the patient's incision that contacts the adjusting claw 41 will gradually tend to change into a curve as it is spread apart. Since the adjusting handle 420 at the upper end of the adjusting claw 41 is lifted, the adjusting claw 41 will rotate to be consistent with the changes in the incision skin, ensuring that the fulcrum of the patient's incision is always on a plane, and the force will not be increased due to the smaller contact point, causing secondary damage to the patient's wound. When the incision is expanded to the required width, the adjusting handle 420 is pressed down, so that the convex point 4210 at the lower end of the rectangular rod 421 contacts the concave point 4230 at the upper end of the rotating rod 423 and locks the rotation direction of the rotating rod 423, thereby preventing the rotation of the rotating rod 423 during the operation from affecting the implementation of the operation.

[0048] Specifically, the movable plate 12 includes a movable longitudinal plate 120 and a cylindrical shaft 121 fixedly connected to one end of the movable longitudinal plate 120;

[0049] The movable longitudinal plate 120 is located in the upper groove 1010 , and the cylindrical shaft 121 passes through the bar-shaped through hole 10120 and is placed in the lower groove 1011 .

[0050] The end of the cylindrical shaft 121 away from the movable longitudinal plate 120 is evenly distributed with teeth 1210; when the bottom of the movable longitudinal plate 120 is forced to move, the cylindrical shaft 121 is driven to move;

[0051] The movable longitudinal plate 120 is located in the upper groove 1010, and the cylindrical shaft 121 passes through the bar-shaped through hole 10120 and is placed in the lower groove 1011; the movable longitudinal plates 120 on different tracks and the cylindrical shaft 121 fixed thereon move synchronously.

[0053] The outer wall of the groove 101 is provided with a scale 1013;

[0054] By threading the positioning column 10111 into the positioning groove 10110 in advance, the moving distance of the movable longitudinal plate 120 is determined in advance, thereby determining the expansion width of the incision, and the scale 1013 effectively assists in the precise control of the distance.

[0055] Specifically, the pushing component 2 includes a strip airbag 20, an air guide tube 21 and an air pump 22. The strip airbag 20 is located in the accommodating cavity 103. One end of the air guide tube 21 is fixedly connected to the strip airbag 20, and the other end penetrates the fixed horizontal plate 10 and is fixedly connected to the air pump 22. The strip airbag 20 is inflated by the air pump 22, and the expansion of the strip airbag 20 pushes the movement of the movable longitudinal plate 120.

[0056] Specifically, the tensioning assembly 3 includes a tensioning shaft 30, a toothed belt 31 and a tensioning line 32. One end of the tensioning shaft 30 is rotatably connected to the left end of the upper groove 1010, and the other end passes through the strip-shaped through hole 10120 and is rotatably connected to the left end of the lower groove 1011. A tooth 2 301 matching the tooth 1 1210 is provided on the end of the tensioning shaft 30 located in the upper groove 1010.

[0058] One end of the tensioning wire 32 is wound around the tensioning shaft 30 located in the lower groove 1011 , and the other end is fixedly connected to the front end of the movable longitudinal plate 120 .

[0059] When the lower end of the movable longitudinal plate 120 moves, the movement of its cylindrical shaft 121 drives the tensioning shaft 30 to rotate through the meshing toothed belt 31, shrinking the tensioning line 32. The shrinkage of the tensioning line 32 drives the upper end of the movable longitudinal plate 120 to move, thereby achieving the purpose of evenly opening the patient's incision.

[0060] Specifically, the fixed longitudinal plate 11 and the movable longitudinal plate 120 are provided with adjustment slots 110 with exactly the same position and length.

[0061] Specifically, the finger assembly 4 includes a fixed finger 40, an adjusting finger 41 and an adjusting handle 42;

[0063] Specifically, the adjusting handle 42 includes an adjusting handle 420, a rectangular rod 421, a fixed sleeve 422 and a rotating rod 423. The lower end of the rotating rod 423 is fixedly connected to the adjusting claw 41, and the upper end thereof is rotatably connected to the lower end of the fixed sleeve 422. The lower end of the rectangular rod 421 is slidably connected to the upper end of the fixed sleeve 422, and the upper end of the rectangular rod 421 is fixedly connected to the adjusting handle 420.

[0064] The rotation and locking of the rotating rod 423 are controlled by the different contact states of the rectangular rod 421 with the rotating rod 423 at different positions of the fixed sleeve 422, so that the rotating rod 423 can ensure that the adjusting claw 41 fixed at its lower end can rotate freely during the incision expansion process.

[0065] Specifically, the lower end of the rectangular rod 421 is provided with evenly distributed convex points 4210 , and the upper end of the rotating rod 423 is provided with concave points 4230 matching the convex points 4210 .

[0066] The rectangular rod 421 can control the rotating rod 423 by virtue of the convex point 4210 at the lower end of the rectangular rod 421 and the concave point 4230 at the upper end of the rotating rod 423 contacting and fitting.

[0067] Specifically, the strip airbag 20 is provided with an exhaust pipe 201, which penetrates the fixed horizontal plate 10 and is placed on its outside; after the operation, the gas in the strip airbag 20 can be released through the exhaust pipe 201, and then the movable longitudinal plate 120 can be returned to its original position and the entire device can be taken out.
