Detailed ways

The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

As shown in Figures 1 to 5, an adjustable bracket for externally expanding a breast augmentation incision comprises a bracket 1, a labor-saving support rod 2 and a retractor 3. A crossbeam axis 4 is fixed on the bracket 1. A strip groove 5 is formed through the side wall of the labor-saving support rod 2. The crossbeam axis 4 movably passes through the strip groove 5. A left slider 6 and a right slider 7 are slidably arranged in the strip groove 5. The left slider 6 and the right slider 7 are respectively located on both sides of the axis of the crossbeam axis 4. The left slider 6 and the right slider 7 both contact the crossbeam axis 4 to form a lever fulcrum. The retractor 3 is detachably mounted on one end of the labor-saving support rod 2. Through the arrangement of the strip groove, the labor-saving support rod can move radially along the crossbeam axis to adjust the deflection fulcrum of the labor-saving support rod, and then the left slider and the right slider are moved to contact with the crossbeam axis to stabilize the fulcrum position of the labor-saving support rod, so that the labor-saving support rod drives the retractor to deflect around the fulcrum to expand the incision. When adjusting the fulcrum, the distance between the end of the retractor and the fulcrum is smaller than the tail of the labor-saving support rod. The distance between the force-saving support rod 2 and the fulcrum is reduced, so that the power arm is larger than the resistance arm, achieving the effect of saving effort, reducing the holding force of the retractor, reducing the intensity of surgical operation, and effectively preventing the occurrence of force loss; secondly, the fulcrum position of the force-saving support rod 2 can be adjusted according to actual conditions, and the distance between the retractor 3 and the incision can be adjusted so that the retractor 3 can enter the incision according to the incision position, and then the force-saving support rod 2 is pressed downward at the end of the force-saving support rod 2 away from the retractor 3, thereby driving the retractor 3 to deflect to open the surgical incision; in specific implementation, in order to make the operation of the force-saving support rod 2 more convenient, a pull rope can be tied to the end of the force-saving support rod 2 away from the retractor 3, and the retractor 3 is driven to deflect to open the incision by pulling the pull rope downward, so that the force-saving support rod 2 can be operated at a long distance, and the handle posture of the retractor 3 can also be changed, so that the doctor can adjust to a more comfortable and convenient position for surgery, which has the advantages of easy use and high practicality.

Furthermore, as shown in FIG2 , an externally threaded tube 30 is fixed on the labor-saving support rod 2. The externally threaded tube 30 is hollow, and the spur rack 11 is passed through the externally threaded tube 30. An internally threaded hole is provided at the tail of the retractor 3. The retractor 3 is threadedly connected to the externally threaded tube 30 to hide the spur rack 11, which facilitates the installation and removal of the retractor 3. After the operation is completed, the retractor can be conveniently removed for cleaning. At the same time, retractors of different sizes and models can be installed on the adjustment bracket to assist in surgery, thereby increasing the scope of use.

The left and right sliders 6 are fixed with sliding grooves 8 at the top and bottom of the left slider 6 and the right slider 7. The sliding grooves 8 are correspondingly adapted in the sliding grooves 8 to limit the moving directions of the left and right sliders 6 and the right sliders 7, and connect the left and right sliders 6 and the labor-saving support rod 2 to prevent the left and right sliders 6 and the right sliders 7 from falling off. The right slider 7 is located between the left slider 6 and the hook 3. The end of the labor-saving support rod 2 away from the hook 3 is threadedly connected with a screw 10. The tail of the screw 10 penetrates into the strip groove 5 and is rotatably connected to the left slider 6. The left slider 6 is driven to move closer to or away from the crossbeam axis 4 by rotating the screw 10. The length of the power arm is extended by the setting of the screw 10. When in use, force is applied to the head of the screw 10 to control the deflection of the hook 3, thereby saving more effort. The end of the labor-saving support rod 2 away from the screw 10 is slidably penetrated with a spur rack 11. The spur rack 11 penetrates into the strip groove 5 and is connected to the right The slider 7 is fixedly connected, and a driving cavity 12 is provided in the labor-saving support rod 2. A driving shaft 13 is rotatably arranged in the driving cavity 12. A gear 14 is keyed on the driving shaft 13, and the gear 14 meshes with the spur rack 11. The gear 14 is driven to rotate by rotating the driving shaft 13. Due to the meshing of the gear 14 with the spur rack 11, the spur rack 11 is driven to move. The spur rack 11 is driven to move away from or close to the beam axis 4 through the positive and negative rotation of the gear 14, thereby driving the right slider 7 to move away from or close to the beam axis 4, so that after the fulcrum position of the labor-saving support rod 2 is adjusted, the left slider 6 and the right slider 7 are both moved to adapt to the beam axis 4, thereby stabilizing the fulcrum of the labor-saving support rod 2; preferably, one end of the left slider 6 close to the beam axis 4 and the other end of the right slider 7 close to the beam axis 4 are both provided with an arc surface 20, and the radius of the arc surface 20 is equal to the radius of the beam axis 4, so that the left slider 6 and the right slider 7 fit the arc surface of the beam axis 4, so that the deflection of the labor-saving support rod 2 on the beam axis 4 is more stable.

Further, as shown in Figure 2, a rectangular groove 15 and a circular hole 16 are sequentially opened on the force-saving support rod 2 in the direction close to the driving cavity 12, and the two ends of the circular hole 16 are respectively connected to the rectangular groove 15 and the driving cavity 12, and the driving shaft 13 is rotatably penetrated in the circular hole 16 through a bearing, and a rectangular block 17 is adapted in the rectangular groove 15, and one end of the driving shaft 13 is slidably penetrated in the rectangular block 17. It should be noted that there is only linear movement freedom between the driving shaft 13 and the rectangular block 17, and there is no rotational freedom. A limiting groove is opened on the inner wall of the rectangular block 17, and a limiting slide is fixed on the outer wall of the driving shaft 13. The rotational freedom between the driving shaft 13 and the rectangular block 17 is limited by the adaptation of the limiting slide and the limiting groove. A spring 18 is arranged in the rectangular groove 15, and the spring 18 is sleeved on the driving shaft 13. One end of the spring 18 is connected The other end of the rectangular block 13 is connected to the step formed by the rectangular groove 15 and the circular hole 16. When the spring 18 is in normal state, the rectangular block 17 is partially adapted in the rectangular groove 15. A pull ring 19 is provided at one end of the rectangular block 17 away from the driving shaft 13. The rectangular block 17 is pulled outward by the pull ring 19 to disengage the rectangular block 17 from the rectangular groove 15. Then the rectangular block 17 is rotated, and the driving shaft 13 is rotated by the rectangular block 17, thereby driving the gear 14 to rotate, so as to drive the spur rack 11 to move and adjust the position of the right slider 7. When the adjustment is completed, the position of the right slider 7 is fine-tuned so that the rectangular block 17 corresponds to the rectangular groove 15. Under the action of the spring 18, the rectangular block 17 is partially adapted in the rectangular groove 15, thereby limiting the rotation of the rectangular block 17, and then limiting the rotation of the gear 14 to stabilize the adjustment position of the right slider 7.

In some embodiments, as shown in Figures 1, 4 and 5, the bracket 1 includes a bar seat 21 and a telescopic rod, and the two ends of the top of the bar seat 21 are fixed with telescopic rods, and the telescopic rod includes a fixed rod 22 and a movable rod 23. One end of the fixed rod 22 is fixedly connected to the bar seat 21, and the other end is slidably penetrated with a movable rod 23. The two ends of the crossbeam axis 4 are respectively connected to two movable rods 23, and the two movable rods 23 move synchronously. The crossbeam axis 4 is driven up and down by the telescopic extension of the telescopic rod to adjust the use height of the hook 3. It should be noted that the two telescopic rods need to be extended and retracted synchronously to prevent interference with the crossbeam axis 4; a cavity 24 is provided in the bar seat 21, and a screw 25 is rotatably provided in the fixed rod 22. The movable rod 23 is threadedly mounted on the screw 25, and one end of the screw 25 penetrates into the cavity 24 and is keyed to a first bevel gear 26. A main shaft 27 is rotatably provided in the cavity 24, and two second bevel gears 28 are keyed to the main shaft 27, and the two second bevel gears 28 are respectively meshed with each other. The two first bevel gears 26 and one end of the main shaft 27 pass through the bar seat 21 and are fixed with a turntable 29. The turntable 29 drives the main shaft 27 to rotate, and the main shaft 27 drives the two second bevel gears 28 to rotate. The meshing of the second bevel gear 28 and the first bevel gear 26 drives the two lead screws 25 to rotate synchronously, so that the movable rods 23 on the two telescopic rods move synchronously, thereby driving the crossbeam shaft 4 to move up and down to adjust the use height of the retractor 3 so that the retractor 3 can be extended into the incision to support the surgical field of view; it should be noted that in order to ensure the synchronous lifting of the two movable rods 23, it should be noted that the installation of the two second bevel gears 28 is opposite, and the two bevel gears 28 are set in the same direction, thereby driving the two lead screws 25 to rotate in the same direction to achieve a synchronous effect; secondly, the synchronous effect can also be achieved by the thread rotation direction of the lead screw 25. Specifically, when the rotation directions of the two lead screws 25 are opposite, the thread rotation directions of the two lead screws 25 are also opposite, so that the movable rods 23 on the two telescopic rods run synchronously.

In summary, the adjustment bracket enables the hook 3 to have four degrees of freedom in four directions. First, the lifting and lowering of the telescopic rod adjusts the use height of the hook 3; second, the axial movement of the labor-saving support rod 2 along the beam axis 4 adjusts the horizontal position of the hook 3; third, the radial movement of the labor-saving support rod 2 along the beam axis 4 adjusts the fulcrum position; fourth, the labor-saving support rod 2 rotates around the fulcrum on the beam axis 4 to drive the hook 3 to deflect and open the surgical incision; when the position of the fulcrum is adjusted, the radial degree of freedom of the labor-saving support rod 2 is limited by the left slider 6 and the right slider 7, and the axial degree of freedom of the labor-saving support rod 2 on the beam axis 4 can be limited by a nut, that is, a thread is provided on the beam axis 4, and two nuts are threadedly connected. After the horizontal position of the labor-saving support rod 2 is adjusted, the two threads are respectively screwed to the two sides of the labor-saving support rod 2, so as to prevent the labor-saving support rod 2 from axially deviating along the beam axis 4 when in use, and the nut does not need to be pressed against the labor-saving support rod 2 to avoid the nut limiting the deflection freedom of the labor-saving support rod 2.
