Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an insulating structure for the support arm of a surgical robot. Background Technology

[0002] Surgical robots, as a crucial component of modern medical technology, require extremely high precision and stability, while ensuring absolute safety during operation. Surgical robots are typically equipped with multiple universal support arms for securing and adjusting various surgical tools, imaging equipment, and so on. Therefore, the electrical performance and safety of these universal support arms directly impact the success rate of the surgery and the safety of the patient.

[0003] Existing universal support arms typically employ a ball joint structure, using internal steel wire rope connections for flexible adjustment and stable positioning. Active support arms utilize the contact between the ball joints (metal components) to achieve conductivity, meeting safety regulations. However, when the support arm in the unlocked state, the significant gaps between the ball joints in existing technologies result in insufficient contact reliability, potentially leading to reduced or even non-conductive circuit performance, affecting normal equipment operation. Furthermore, because the ball joints and end metal components of the support arm are exposed, when an external power source contacts the support arm, the entire support arm and its end-connected metal components may become energized, posing a serious risk of electric shock and endangering the safety of operators and patients.

[0028] Please see Figures 1 to 4 As shown in the embodiment of this application, an insulating structure for a support arm of a surgical robot is provided. The support arm includes several ball joints, which are connected end-to-end to form a joint chain 10. The insulating structure of the support arm of the surgical robot includes a first insulating member 20, a second insulating member 30, a first fixing component 40, a metal connector 50, and a metal fixing frame 60, wherein:

[0029] The first end of the metal connector 50 is connected to the metal bracket 60, and the metal bracket 60 is configured to mount the probe 61.

[0030] The first end of the joint chain 10 is connected to the first end of the first insulator 20, the first end of the second insulator 30 is fitted over the second end of the first insulator 20, the second end of the second insulator 30 is connected to the second end of the metal connector 50, and the first fixing assembly 40 is configured to connect the first insulator 20 and the second insulator 30 into one unit.

[0031] The cooperation of the first insulating member 20, the second insulating member 30 and the first fixing component 40 not only achieves effective insulation between the joint chain 10 and the metal connector 50 and the metal fixing frame 60, preventing the operator holding the end metal fixing frame 60 from being electrocuted, but also has a simple structure that is easy to operate and install.

[0032] In one embodiment, the first fixing component 40 includes a fixing member 41 and a screw 42. The first end of the fixing member 41 is fixedly connected to the first end of the joint chain 10, and the second end of the fixing member 41 is along a first direction ( Figure 1A threaded hole is provided in the X direction, and the screw 42 is screwed into the threaded hole in the first direction. A limit ring 420 is fixedly provided at the first end of the screw 42.

[0033] The first insulating component 20 is fitted onto the second end of the fixing component 41, and the first end of the second insulating component 30 is fitted onto the first end of the screw 42. The inner wall of the first insulating component 20 is provided with a first protruding ring 21, which abuts against the fixing component 41 and the second insulating component 30 along the first direction.

[0034] The second end of the second insulating member 30 extends outward to form a receiving groove 31. The limiting ring 420 abuts against the bottom of the receiving groove 31 so that the limiting ring 420 is driven by the screw 42 to apply pressure to the first insulating member 20 and the second insulating member 30 in the first direction.

[0035] The cooperation of the fixing member 41, the limiting ring 420 and the screw 42 applies pressure to the first insulating member 20 and the second insulating member 30, ensuring a stable connection between the two and enhancing the stability of the insulating part of the support arm and the reliability of the connection.

[0036] In one embodiment, a connecting sleeve 32 is fitted over the first insulating member 20 and the second insulating member 30. A second protruding ring 320 is provided on the inner wall of the connecting sleeve 32. The second protruding ring 320 abuts against the first insulating member 20 and the second insulating member 30 along a first direction. A metal connector 50 is screwed onto the connecting sleeve.

[0037] By fitting a connecting sleeve 32, which is screwed onto the metal connector 50, onto the first insulating member 20 and the second insulating member 30, the metal connector 50 can be quickly and securely connected, improving the efficiency of equipment assembly. Furthermore, by providing a second convex ring 320, the secure connection of the connecting sleeve 32 to the insulating components is further ensured, improving the safety of equipment operation.

[0038] In one embodiment, the insulating structure of the support arm of the surgical robot also includes a universal arm body 70, which is fixedly connected to the second end of the joint chain 10. A flexible insulating cover 11 is sealed on the outer periphery of the joint chain 10.

[0039] By sealing the joint chain 10 with a flexible insulating cover 11, the external power source is prevented from contacting the metal parts of the support arm, thereby avoiding the risk of electric shock. At the same time, the metal parts of the joint chain 10 are prevented from being exposed to the external environment and damaged or contaminated, thus improving the reliability of equipment operation.

[0040] In one embodiment, the flexible insulating cover 11 is configured as a corrugated tube made of silicone material.

[0041] By setting the flexible insulating cover 11 as a corrugated tube made of silicone material, the good insulation and elasticity of the silicone corrugated tube can effectively protect the joint chain 10 from external impact without affecting the degree of freedom of movement of the joint chain 10, while maintaining good electrical insulation during the operation.

[0042] In one embodiment, the third fixing component 13 includes a first mounting sleeve 130 and a second mounting sleeve 131. The first end of the first mounting sleeve 130 contacts the outer wall of the connecting sleeve 32. The outer wall of the connecting sleeve 32 is provided with a third protruding ring 321. The first end of the first mounting sleeve 130 abuts against the third protruding ring 321 and the metal connector 50 in a first direction. The second end of the first mounting sleeve 130 expands outward toward the joint chain 10 to surround the first insulating member 20. The second mounting sleeve 131 is screwed to the inner wall of the second end of the first mounting sleeve 130. The first end of the flexible insulating cover 11 is located between the second mounting sleeve 131 and the first insulating member 20. The first mounting sleeve 130 applies pressure to the second mounting sleeve 131 in a vertical direction to fix the first end of the flexible insulating cover 11.

[0043] The first mounting sleeve 130 and the second mounting sleeve 131 work together to effectively fix the first end of the flexible insulating cover 11, thereby enhancing the overall insulation of the joint chain 10.

The second end of the flexible insulating cover 11 is disposed between the third mounting sleeve 120 and the fourth mounting sleeve 121.

[0045] The cooperation of the third mounting sleeve 120, the fourth mounting sleeve 121 and the bolt 122 ensures that the second end of the flexible insulating cover 11 is firmly connected to the joint chain 10, which helps to maintain the sealing performance and electrical isolation effect of the insulating cover. The fixing force provided by the bolt 122 ensures that the components will not loosen during the installation process, thus enhancing the stability of the overall structure.

[0046] In one embodiment, both the third mounting sleeve 120 and the fourth mounting sleeve 121 are made of plastic.

[0047] By using plastic material to make the third mounting sleeve 120 and the fourth mounting sleeve 121, the overall electrical safety is improved by taking advantage of their good electrical insulation properties.
