DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] like Figures 1 to 6As shown, a specific embodiment of the utility model provides an opener fixing frame for cooperating with robot surgery, including a fixing frame body 1 and an opener 2 arranged at the end of the fixing frame body 1, the fixing frame body 1 is provided with a rotating block 3, the rotating block 3 is fixedly connected with a connecting rod 4, and the opener 2 is arranged on the connecting rod 4, and the connecting rod 4 is provided with a connecting component for limiting and fixing the opener 2. By setting the connecting component, the rod portion on the opener 2 can be limited and fixed, so that the opener 2 can be directly connected to the fixing frame body 1, and the connecting component includes a locking screw 5 threadedly connected to the connecting rod 4, and a pressure rod 6 is fixedly connected to the locking screw 5.

[0027] like Figures 1 to 6 As shown, specifically, a boss 7 is provided on the connecting rod 4, and the end of the opener 2 is in close contact with the boss 7, a cylindrical groove 8 is provided in the connecting rod 4, a limited circular plate 9 is slidably connected in the cylindrical groove 8, and the limited circular plate 9 is fixedly connected to the locking screw 5, a rotating wheel 10 is fixedly connected to the pressure rod 6, and a cushion is provided on the rotating wheel 10. The setting of the cushion can make it possible to better rotate the rotating wheel 10 when using the device, bringing comfort to the hand. When the opener 2 is limited and fixed, the tail end of the opener 2 is sleeved on the connecting rod 4, so that the end of the opener 2 is in close contact with the boss 7, and then the rotating wheel 10 is rotated to drive the pressure rod 6 and the locking screw 5 to rotate. Since the locking screw 5 is threadedly connected to the connecting rod 4, the pressure rod 6 on the locking screw 5 gradually approaches the opener 2, and then when the rotating wheel 10 is rotated Under the action of , the pressure rod 6 can apply pressure to the opener 2 to limit and fix it. In the process of rotating the wheel 10, the locking screw 5 gradually pushes the limiting circular plate 9 at the bottom to move in the cylindrical groove 8. The setting of the cylindrical groove 8 allows the locking screw 5 to move toward the inside of the connecting rod 4, and the reverse rotation of the wheel 10 causes the locking screw 5 to rotate in the reverse direction, so that the pressure rod 6 gradually disengages from the opener 2, thereby canceling the pressure on the opener 2, and then the opener 2 can be pulled to separate from the fixing frame body 1, and the setting of the limiting circular plate 9 can limit the locking screw 5. On the contrary, if the rotating wheel 10 is rotated too many times, the locking screw 5 will fall off from the connecting rod 4, thereby avoiding the situation where the locking screw 5 falls off due to the locking screw 5 falling off from the connecting rod 4.

[0028] like Figures 1 to 6As shown, specifically, a movable groove 11 is provided on the rotating block 3, the fixed frame body 1 is arranged in the movable groove 11, a groove 12 is provided on the fixed frame body 1, a rotating shaft 13 is fixedly installed on the rotating block 3, and the rotating shaft 13 is rotatably connected to the groove 12, a receiving groove 14 is provided on the rotating block 3, a pressing plate 15 is provided in the accommodating groove 14, a rotating rod 16 is fixedly connected to the pressing plate 15, and the rotating rod 16 is threadedly connected to the rotating block 3, and a rotating plate 17 is fixedly connected to the rotating rod 16. The setting of the movable groove 11 allows the fixed frame body 1 to rotate in the movable groove 11, so that the angles of the rotating block 3 and the connecting rod 4 can be adjusted, and then the fixing angle of the opener 2 can be adjusted. Rotating the rotating block 3 causes the rotating shaft 13 on the rotating block 3 to rotate in the groove 12, thereby adjusting the angle of the rotating block 3. After adjusting the angle, rotating the rotating plate 17 drives the rotating rod 16 to rotate. Since the rotating rod 16 is threadedly connected to the rotating block 3, the rotating rod 16 pushes the pressing plate 15 in the accommodating groove 14 to be close to the fixing frame body 1 in the movable groove 11 and exerts pressure thereon, thereby completing the limited fixation between the rotating block 3 and the fixing frame body 1. A rubber pad layer 18 is provided in the pressing plate 15, and the surface of the rubber pad layer 18 is rough. The rubber pad layer 18 and its surface roughness can increase friction, thereby strengthening the fixing effect of the pressing plate 15 on the fixing frame body 1.
