[0001] The utility model relates to the technical field of universal fixing frames, and particularly relates to a universal fixing frame for cooperating with robot surgery. Background Technique

[0002] A universal fixing frame is a device with multi-directional adjustment and fixing capabilities, designed to support, fix, or adjust devices, tools, or instruments. In medical treatment, when using an oral speculum to perform certain treatments or examinations on a patient, after the oral speculum is placed in the patient's mouth, it usually needs to be held by a doctor or an assistant all the time to ensure the accuracy and stability of its position.

[0003] Most existing hospitals lack a dedicated bracket for limiting and fixing the oral speculum, so doctors or assistants need to manually hold the oral speculum, and holding it for a long time is likely to cause excessive fatigue of medical staff, thus greatly increasing the medical risk.

[0004] Therefore, a universal fixing frame for cooperating with robot surgery is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a universal fixing frame for cooperating with robot surgery to solve the problem that most existing hospitals lack a bracket for limiting and fixing the oral speculum, so doctors or assistants need to manually hold the oral speculum, and holding it for a long time is likely to cause excessive fatigue of medical staff, thus greatly increasing the medical risk as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A universal fixing frame for cooperating with robot surgery, including an adjusting rod that can be adjusted in position in multiple directions. A receiving groove is provided on the adjusting rod, and a threaded rod is provided in the receiving groove. A clamping assembly for limiting and fixing the oral speculum is provided on the threaded rod. The clamping assembly includes a locking rod fixedly connected to the end of the threaded rod. A pressing handwheel is threadedly connected to the threaded rod, and a pressing outer sleeve that cooperates with the locking rod for clamping is provided between the pressing handwheel and the threaded rod.

[0007] Preferably, a ball head is fixedly connected to the threaded rod, and the ball head is clamped in the receiving groove.

[0008] Preferably, a yuan nut is fixedly installed on the threaded rod, and a plurality of grooves are provided on the yuan nut.

[0009] Preferably, a plurality of rotating handles are fixedly connected to the pressing handwheel, and rubber sleeves are provided on the rotating handles.

[0010] Preferably, a long groove is provided in the pressing outer sleeve, a spring is arranged between the long grooves, and the spring is fixedly connected between the pressing outer sleeve and the locking rod.

[0011] Preferably, a limit pin is fixedly connected in the pressing outer sleeve, a limit groove is provided on the threaded rod, and the limit pin is slidably connected in the limit groove.

[0012] Preferably, the locking rod and the pressing outer sleeve are both provided with concave-convex patterns, and a soft rubber layer is arranged in the concave-convex patterns.

[0013] The beneficial effects of the present utility model:

[0014] By setting the clamping assembly, the present utility model rotates the pressing handwheel to push the pressing outer sleeve to gradually move towards the locking rod on the threaded rod, so as to limit and fix the connecting rod on the opener between the locking rod and the pressing outer sleeve, and maintain the stability of the opener. When the pressing handwheel is rotated in the reverse direction, the pressing outer sleeve can move away from the locking rod under the reaction force of the spring, so as to cancel the clamping and fixing of the connecting rod, and then the opener can be removed. The whole process enables the opener to be used without the need for medical staff to manually support it for a long time, saving time and effort, and avoiding the situation that medical staff are overworked due to long-term support, increasing the medical risk.

[0025] As Figures 1 to 5 shown, a specific embodiment of the present utility model provides a universal fixing frame for robot-assisted surgery, which includes an adjusting rod 1 that can be adjusted in multiple directions. A receiving groove 2 is provided on the adjusting rod 1, and a threaded rod 3 is provided in the receiving groove 2. A clamping assembly for limiting and fixing the opener is provided on the threaded rod 3. By setting the clamping assembly, the opener can be clamped and fixed, so that it is not necessary for medical staff to manually hold the opener, which is convenient for the use of the opener. The clamping assembly includes a locking rod 4 fixedly connected to the end of the threaded rod 3. A pressing handwheel 5 is threadedly connected to the threaded rod 3, and a pressing outer sleeve 6 that cooperates with the locking rod 4 for clamping is provided between the pressing handwheel 5 and the threaded rod 3.

[0026] As Figure 2 and Figure 3As shown, specifically, a ball head 7 is fixedly connected to the threaded rod 3, and the ball head 7 is clamped in the receiving groove 2. A yuan nut 8 is fixedly installed on the threaded rod 3, and a number of grooves are provided on the yuan nut 8. When using this device to clamp and fix the mouth opener, the adjusting rod 1 is inserted into the fixed seat for fixation, and then the fixed seat is fixed on the operating table. The fixed seat for limiting and fixing the adjusting rod 1 is prior art and will not be elaborated here. After fixing the adjusting rod 1, by rotating the yuan nut 8, the threaded rod 3 and the ball head 7 are driven to rotate, so that the ball head 7 rotates in the receiving groove 2, and thus the angular position of the threaded rod 3 can be adjusted to find the angular position suitable for the patient. A number of rotating handles 9 are fixedly connected to the pressing handwheel 5, and rubber sleeves are provided on the rotating handles 9. The locking rod 4 is adjusted to the connecting rod where the mouth opener can be limited and fixed, and the connecting rod is placed between the locking rod 4 and the pressing outer sleeve 6. By holding the yuan nut 8 and rotating the handle 9 to rotate the pressing handwheel 5, the setting of the rubber sleeve can increase the friction and facilitate the medical staff to rotate the pressing handwheel 5. The rotation of the pressing handwheel 5 drives the pressing outer sleeve 6 to move along the threaded rod 3 towards the locking rod 4.

[0027] As Figures 1 to 5 shown, specifically, a long groove 10 is provided in the pressing outer sleeve 6, a spring 11 is provided between the long grooves 10, and the spring 11 is fixedly connected between the pressing outer sleeve 6 and the locking rod 4. When the pressing outer sleeve 6 moves towards the locking rod 4, the spring 11 in the long groove 10 is stressed and contracts to generate a reaction force. A limit pin 12 is fixedly connected in the pressing outer sleeve 6, a limit groove 13 is provided on the threaded rod 3, and the limit pin 12 is slidably connected in the limit groove 13. The movement of the pressing outer sleeve 6 towards the locking rod 4 causes the limit pin 12 to move in the limit groove 13. Under the cooperation of the limit groove 13 and the limit pin 12, the pressing outer sleeve 6 will not rotate during movement. Concave-convex patterns 14 are provided on both the locking rod 4 and the pressing outer sleeve 6, and a soft rubber layer is provided in the concave-convex patterns 14. During the movement of the pressing outer sleeve 6 towards the locking rod 4, the connecting rod between the pressing outer sleeve 6 and the locking rod 4 is limited and fixed, that is, the mouth opener is limited and fixed. The setting of the concave-convex patterns 14 increases the roughness of the contact surface, thereby enhancing the fixing effect on the connecting rod. The setting of the soft rubber layer facilitates the protection of the connecting rod. When removing the mouth opener and no longer fixing it, rotate the pressing handwheel 5 in the reverse direction, and the pressing outer sleeve 6 moves in the reverse direction under the reaction force of the spring 11. The pressing outer sleeve 6 moves in the reverse direction and gradually moves away from the locking rod 4, so that the connecting rod is no longer fixed, and then the mouth opener can be removed.
