Detailed implementation mode
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0023] Please refer to Figures 1-4 , the present invention provides a technical solution: a laparoscopic cutting stapler capable of angle adjustment, including: a cutting stapler main body 1, a rotating handle 2 is connected to the left side of the cutting stapler main body 1, a sleeve 3 is inserted and connected to the inside of the left side of the rotating handle 2, a controller 4 is connected to the inside of the sleeve 3, adjusting elastic steel bars 5 are inserted and connected to the front and rear sides inside the controller 4, sliding grooves 6 are opened on the front and rear sides of the rotating handle 2, a slider 7 is inserted and connected to the inside of the sliding groove 6, the right side of the adjusting elastic steel bar 5 passes through the controller 4 and is fixedly connected to the inner side of the slider 7, the left side of the adjusting elastic steel bar 5 passes through the controller 4 and extends to the left side, a terminal controller 8 is arranged on the left side of the sleeve 3, a staple cartridge seat 9 is rotatably connected to the left side of the terminal controller 8, adjusting elastic steel bars two 10 are inserted and connected to the front and rear sides inside the terminal controller 8, the left sides of the adjusting elastic steel bars two 10 are fixedly connected to the front and rear sides of the right end of the staple cartridge seat 9, hooks 11 are connected to the right sides of the adjusting elastic steel bars two 10 and the left side of the adjusting elastic steel bar 5, a joint head protective sleeve is wrapped outside the connection between the terminal controller 8 and the staple cartridge seat 9, and the cutting stapler main body 1 is electrically connected to the controller 4, the terminal controller 8, and the staple cartridge seat 9.
[0024] When in use, after the terminal controller 8 and the left side of the sleeve 3 are aligned and inserted and connected, a 90° rotation is performed. At this time, the hooks 11 will be inserted into each other, so that the adjusting elastic steel bar two 10 and the adjusting elastic steel bar 5 are connected. When the angle of the staple cartridge seat 9 needs to be adjusted, push the slider 7 on one side, and the slider 7 will move back and forth along the slide rail 6. One end of the adjusting elastic steel bar 5 is fixedly connected to the inner side of the slider 7. At this time, the adjusting elastic steel bar 5 will pull the adjusting elastic steel bar two 10 to move through the hook 11. The terminal controller 8 and the staple cartridge seat 9 are rotatably connected, and the ends of the adjusting elastic steel bar two 10 are fixedly connected to the front and rear sides of the staple cartridge seat 9, so that the right side of the staple cartridge seat 9 rotates around the controller 8 to adjust the angle.
[0025] Such as Figures 1-3As shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the outer and inner sides of the slider 7 are of a split structure. A rotating torsion 21 is rotatably connected inside the outer slider 7. A bolt is connected to the rear end of the rotating torsion 21. The bolt at the rear end of the rotating torsion 21 passes through the outer slider 7, and the bolt at the rear end of the rotating torsion 21 is threadedly connected to the inner slider 7.
[0026] Analyzing the above structure, after adjusting the angle of the cartridge seat 9 to the required angle, rotate the rotating torsion 21. At this time, the bolt will pull the inner slider 7 to move outwards, so that the slider 7 clamps the chute 6, making it difficult for the slider 7 to move and preventing the angle from changing during the operation.
[0027] As Figures 1-4 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, the maximum rotation angle of the cartridge seat 9 is 45°.
[0028] Analyzing the above structure, it can adapt to the angles in most surgical procedures.
[0029] As Figures 1-2 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, angle markings are provided on the outer side of the rotation handle 2 at the upper and lower ends of the chute 6.
[0030] Analyzing the above structure, when adjusting the angle, the angle markings can be referred to to judge the angle at the front end of the cartridge seat 9, and it is also convenient to adjust the cartridge seat 9 to a position perpendicular to the cannula 3 when taking it out.
[0031] As Figures 1-3 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, rollers 22 are rotatably connected to the front and rear sides at the left end inside the rotation handle 2. The rollers 22 are tangent to the adjustment elastic steel strip 5. A chamfer is provided at the connection between the left side of the end controller 8 and the adjustment elastic steel strip two 10.
[0032] Analyzing the above structure, when adjusting the position of the slider 7, the outer side of the adjustment elastic steel strip 5 contacts the outer side of the roller 22 to reduce the stress at the corner. The chamfer provided at the connection between the left side of the end controller 8 and the adjustment elastic steel strip two 10 can reduce the friction between the adjustment elastic steel strip two 10 and the end controller 8 and reduce wear.
[0033] As Figures 1-2 shown in the figure, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, rubber pads are provided at the positions where the inside of the end controller 8 is connected to the adjustment elastic steel strip two 10 and at the positions where the inside of the adjustment elastic steel strip 5 is connected to the adjustment elastic steel strip 5.
[0034] Analyzing the above structure, it can be seen that these rubber pads are in contact with the surfaces of the adjusting elastic steel strip II 10 and the adjusting elastic steel strip 5, which are true or false in the resistance when adjusting the angle, and help to control precisely.
[0035] As Figures 1-4 shown, an embodiment of the present invention provides an implementation manner. Based on the above implementation manner, a groove is formed in the middle of the left side of the end controller 8.
[0036] Analyzing the above structure, it can be seen that when the cartridge holder 9 moves to the middle position, the right side of the cartridge holder 9 will be stuck into the inside of the groove, which is convenient to find the vertical position when pulling out.
