[0027] Example: Reference Figure 1-4 The steering device for an electric thoracoscopic cutting and stapling device shown in the figure comprises an adjustment box and a steering bracket 7. The internal space of the adjustment box 3 is divided into a driving compartment 9 and a transmission compartment 10 by a partition. A transmission plate 12 is slidably matched in the transmission compartment 10, and a threaded screw 14 is rotatably connected in the transmission compartment 10. The threaded screw 14 penetrates the transmission plate 12 and is threadedly connected to the transmission plate 12. One end of the threaded screw 14 penetrates the partition and is fixedly connected to a secondary bevel gear 15. A rotating rod 5 is rotatably connected in the driving compartment 9. A main bevel gear 11 is fixed to the bottom end of the rotating rod 5. The main bevel gear 11 is meshed with the secondary bevel gear 15. A slider 18 is slidably matched on the steering bracket 7. One end of the upper surface of the slider 18 is fixedly connected to the transmission plate 12. One end of the slider 18 is connected to a steering connecting rod 8. When the transmission plate 12 moves laterally, it can drive the slider 18 to move laterally. One end of the steering connecting rod 8 drives the staple cartridge assembly of the electric thoracoscopic cutting and stapling device to swing left and right to achieve steering.
[0028] During the rotation of the rotating rod 5, the meshing connection between the main bevel gear 11 and the auxiliary bevel gear 15 drives the threaded screw 14 to rotate, so that the vertical transmission of the rotating rod 5 is converted into a horizontal transmission. This meshing connection has high transmission efficiency. The threaded connection between the threaded screw 14 and the transmission plate 12 can make the transmission plate 12 move slowly and stably in the transmission bin 10. The steering bracket 7 can make the slider 18 slide stably and laterally on its surface, thereby driving the slider 18 and the steering link 8 to move slowly, so that the steering link 8 can slowly drive the staple cartridge assembly of the electric thoracoscopic cutting stapler to swing left and right, which is convenient for the operator to accurately control the swing of the staple cartridge assembly, and also avoids secondary injury to the patient.
[0029] In this embodiment, an upper shell 1 is also included, a lower shell 2 is fixed to the bottom of the upper shell 1, a steering bracket 7 is fixed to the bottom of the lower shell 2, and an adjustment box 3 is passed through and fixed to the upper shell 1. The fixed connection between the upper shell 1 and the lower shell 2 plays the role of a shell bracket, including and supporting the adjustment box 3 and the steering bracket 7 inside.
[0030] In this embodiment, a sleeve 4 is provided on the adjusting box 3, the top end of the rotating rod 5 passes through the sleeve 4 and is rotatably connected to the sleeve 4, and a knob 6 is fixed to the top end of the rotating rod 5, two guide rods 16 are fixed in the transmission compartment 10, the transmission plate 12 is slidably sleeved on the outside of the guide rods 16, and a bottom plate 13 is fixed to the bottom end of the transmission plate 12. The upper surface of the bottom plate 13 is in sliding contact with the bottom surface of the adjusting box 3, and a connecting rod 19 is fixed to the lower surface of the bottom plate 13, and the bottom end of the connecting rod 19 is fixedly connected to one end of the upper surface of the slider 18. By rotating the knob 6, the rotating rod 5 can be driven to rotate stably. The setting of the sleeve 4 can make the rotating rod 5 more stably connected to the adjusting box 3 for rotation. During the lateral movement of the transmission plate 12, the bottom plate 13 will stick to the bottom surface of the adjusting box 3 and slide laterally, so that the bottom plate 13 and the connecting rod 19 drive the slider 18 to move more stably, reducing the shear force applied to the transmission plate 12 during the movement of the slider 18, and improving the structural strength of the transmission plate 12. The setting of the guide rod 16 improves the stability of the transmission plate 12 when it moves laterally in the transmission bin 10, and improves the structural strength.
[0031] In this embodiment, a slide groove 17 is provided on the upper surface of the steering bracket 7, and a slider 18 is slidably fitted in the slide groove 17. Limiting grooves 21 are provided on both groove walls of the slide groove 17. Limiting plates 22 are fixed on both sides of the slider 18, and the limiting plates 22 are slidably fitted in the limiting grooves 21. The sliding fit between the slide groove 17 and the limiting plates 22 can limit the slider 18 inside the slide groove 17, so that the slider 18 can stably move laterally in the slide groove 17.
[0032] Working principle: When the steering device for the electric thoracoscopic cutting and suturing device is used, the upper shell 1 and the lower shell 2 are installed and fixed together, and the stapling assembly is hooked with one end of the steering link 8. When the user adjusts the angle of the stapling assembly of the electric thoracoscopic cutting and suturing device, the operator rotates the knob 6 to drive the rotating rod 5 to rotate, and the vertical transmission is converted into a horizontal transmission through the meshing connection between the main bevel gear 11 and the auxiliary bevel gear 15. The screw rod 14 drives the transmission plate 12 to move horizontally in the transmission bin 10, and the slider 18 is adjusted to slide on the inner side of the slide groove 17 through the bottom plate 13 and the connecting rod 19. The slider 18 drives the steering link 8 to move horizontally synchronously, and the left and right lateral movement of the steering link 8 drives the stapling assembly connected thereto to swing. The left and right lateral movement of the steering link 8 can be controlled by controlling the rotation direction of the knob 6.
