Description

Technical Field

[0001] This application relates to the field of medical devices, and particularly to a portable multi-legged robot. Background Art

[0002] Traditional orthopedic surgeries are large-scale open surgeries with significant trauma. During the operation, doctors often rely on their years of experience, resulting in a high risk of surgery and great uncertainty in the surgical outcome. Also, because traditional orthopedic surgeries have high requirements for doctors, the threshold of orthopedic surgeries is thus raised.

[0003] With the development of technology and continuous progress, many mechanical devices for assisting orthopedic surgeries have emerged on the market, collectively referred to as orthopedic surgical robots. However, most of the existing orthopedic surgical robots on the market use large multi-axis robotic arms as operating devices. Due to the immaturity of domestic technology levels, the flexibility and safety of domestic robotic arms rarely meet the requirements for participating in surgeries. Most of the robotic arms used in surgical robots on the market are imported from abroad, further increasing the production cost of surgical robots and thus raising the usage threshold. Many hospitals with insufficient funds are unable to purchase expensive surgical robots. Summary of the Invention

[0004] To reduce the production cost of orthopedic surgical robots and replace traditional multi-axis robotic arms, this application provides a portable multi-legged robot.

[0035] The following further elaborates on this application in conjunction with the attached Figure 1-2 drawings for a more detailed explanation.

[0036] The embodiment of this application discloses a portable multi-legged robot.

[0037] Referring to Figure 1 and Figure 2 , a portable multi-legged robot includes a manipulator mount 1. A bolt is fixedly connected to the manipulator mount 1 to an end connector 2. An end platform 5 is provided on the end connector 2. The end platform 5 is rotatably connected to the end connector 2. A fixed ear 51 is provided on the end platform 5. The fixed ear 51 is fixedly connected to the end platform 5 by a bolt. The fixed ear 51 is connected to a mounting tube 52 for installing an end device for surgery. The mounting tube 52 is rotatably connected to the fixed ear 51.

[0038] When the operator installs the end device on the mounting cylinder 52, the operator can adjust the surgical angle of the end device through the rotational relationship between the mounting cylinder 52 and the fixed ear 51; the operator can also adjust the surgical angle of the end device from other degrees of freedom directions through the rotational relationship between the end platform 5 and the end connecting seat 2. A braking member 53 is provided on the fixed ear 51. The braking member 53 adopts electromagnetic automatic braking and uses the principle of power-off braking to lock the positional relationship between the adjusted mounting cylinder 52 and the fixed ear 51, which can prevent the end device from deviating from the initially set surgical position during the operation and improve the safety and reliability of the portable multi-legged robot.

[0039] A fixing mechanism 3 and a supporting mechanism 4 are also provided on the robotic arm mounting seat 1. The two ends of the supporting mechanism 4 are respectively connected to the fixing mechanism 3 and the robotic arm mounting seat 1.

[0040] The supporting mechanism 4 includes three supporting feet, which support the portable multi-legged robot from three points, can ensure good stability, and thus improve the safety during the operation. The supporting foot includes a first supporting portion 41 and a second supporting portion 42. The first supporting portion 41 and the second supporting portion 42 are rotatably connected. One end of the first supporting portion 41 away from the second supporting portion 42 is hinged to the robotic arm mounting seat 1, and one end of the second supporting portion 42 away from the first supporting portion 41 is hinged to the fixing mechanism 3. The position of the portable multi-legged robot can be adjusted through the rotational relationship between the first supporting portion 41 and the second supporting portion 42, thereby improving the flexibility and application range of the portable multi-legged robot and making it applicable to more usage scenarios.

[0041] The second supporting portion 42 includes two parallel support rods II, which further improve the structural strength and stability of the supporting foot through the two support rods; the first supporting portion 41 includes a support rod I, and the diameter of the support rod I is greater than the diameter of the support rod II. By thickening the support rod I, the structural strength and stability of the supporting foot are enhanced, the overall appearance of the supporting foot is simplified, making the portable multi-legged robot more concise and beautiful, and at the same time, the production cost is reduced through the simple structure.

[0042] A protection member 43 is provided on the supporting foot. The protection member 43 is used to brake the rotation between the first supporting portion 41 and the second supporting portion 42. The protection member 43 also adopts electromagnetic automatic braking like the braking member 53 and uses the principle of power-off braking to lock the adjusted first supporting portion 41 and the second supporting portion 42.

[0043] The fixing mechanism 3 includes three connecting members, and the three connecting members are all hinged to the supporting mechanism 4, which can further improve the flexibility and application range of the portable multi-legged robot.

[0044] The connecting piece includes a base 31, a negative pressure ball 32, an intermediate suction cup 33 and an outer suction cup 34. The base 31 is hinged to the second support portion 42. The negative pressure ball 32 is threadedly connected to the base 31. The intermediate suction cup 33 is connected to the base 31. The outer suction cup 34 is connected to one side of the intermediate suction cup 33 away from the base 31. Both the intermediate suction cup 33 and the outer suction cup 34 are communicated with the negative pressure ball 32. When the operator determines the installation position of the portable multi-legged robot on the human body, the operator can directly hold the negative pressure ball 32 between the outer suction cup 34 and the human body surface, apply force to discharge the air in the negative pressure ball 32, then press the outer suction cup 34 tightly against the human body surface, and then release the negative pressure ball 32 to suck the air in the outer suction cup 34, thus completing the installation work of the portable multi-legged robot.

[0045] A plurality of suction cup grooves 341 are formed on the surface of the outer suction cup 34 away from the intermediate suction cup 33. By means of a large number of suction cup grooves 341, the contact area between the outer suction cup 34 and the human body surface is increased, so as to enhance the suction force of the connecting piece, thereby reducing the possibility of the portable multi-legged robot moving during the operation.

[0046] The implementation principle of a portable multi-legged robot in an embodiment of the present application is as follows: the portable multi-legged robot can be directly connected to the human body surface through the fixing mechanism 3, so that the existing navigation device can accurately monitor the changes generated by the end device for surgery following the movement of the human body, and the reliability and success rate of the operation can be improved; the portable multi-legged robot is supported by three support legs with simple structures and stable strengths, replacing the traditional large multi-axis robotic arm, and the production cost can be reduced; also, since the first support portion 41 and the second support portion 42 are rotatably connected, the first support portion 41 is hinged to the robotic arm mounting seat 1, the second support portion 42 is hinged to the fixing mechanism 3, and the end platform 5 and the end connecting seat 2 are rotatably connected, the flexibility of the portable multi-legged robot is improved, and the end device for surgery can be adjusted from multiple angles and degrees of freedom, thereby expanding the application range of the portable multi-legged robot; in addition, the overall safety of the portable multi-legged robot is improved by the protection member 43 and the braking member 53.
