Description

Technical Field

[0001] This invention belongs to the field of surgical robot technology, and more specifically, relates to a switch handle with dual touch control function. Background Technology

[0002] To prevent accidental activation during surgery, surgical robots are equipped with two unlocking buttons. The robotic arm can only unlock when both buttons are pressed simultaneously. Currently, surgical robots have two drawbacks in use: 1. Directly pressing the two buttons through the sterile membrane can easily cause slippage and loss of hand, resulting in the robotic arm falling due to gravity before relocking, posing a surgical risk. Additionally, the large diameter of the robotic arm's end cap makes the two buttons too far apart, making it difficult to grip when adjusting the robotic arm's angle; 2. While using a "dual-touch control switch handle" available on the market allows for convenient gripping and simultaneous control of both buttons, it presents the problem of inconvenient hand orientation for unlocking, requiring adjustment of the robotic arm's posture. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a switch handle with dual touch functionality. This switch handle is easy to grip and unlocks two buttons on the front of the robotic arm via a transmission component. The direction of the switch handle is the same as the direction of the line connecting the two buttons on the front of the robotic arm, which facilitates the adjustment of the robotic arm's posture.

[0004] To achieve the above objectives, the present invention provides a switch handle with dual touch functionality, comprising:

[0005] A fixing component, one end of which is connected to the passive arm, and the other end of the fixing component has a sliding groove inside;

[0006] A transmission assembly is movably disposed within a slide groove. The transmission assembly includes a spring and an operating part. The operating part is the portion of the transmission assembly that extends from the other end of the fixed assembly. The spring enables the transmission assembly to extend towards the other end of the fixed assembly.

[0007] The touch arm is connected to the other end of the transmission assembly. When the operating part is pressed into the fixing assembly, the transmission assembly drives the touch arm to contact the unlock button of the robotic arm.

[0008] Optionally, the transmission assembly includes:

[0009] The first transmission rod has an operating part at one end and a first rotating shaft at the middle.

[0010] The second transmission rod has one end connected to the inner wall of the slide groove via the spring, and a second rotating shaft is provided in the middle of the second transmission rod;

[0011] The third transmission rod is rotatably disposed in the slide groove, and long waist holes are respectively opened at both ends of the third transmission rod, and the long waist holes are slidably engaged with the first rotating shaft and the second rotating shaft respectively;

[0013] Optionally, the other end of the first transmission rod extends to the outside of the fixing assembly, and a limit rod is provided at the other end of the first transmission rod. The limit rod is perpendicularly connected to the first transmission rod. When the operating part extends out of the fixing assembly under the action of the spring, the limit rod abuts against the other end of the second transmission rod.

[0014] Optionally, the elongated hole is provided along the length direction of the third transmission rod.

[0015] Optionally, the operating part is a button, and the end of the button is set as an arc surface.

[0019] The upper cover is detachably connected to the base. The upper cover has a second sliding groove. When the upper cover is fastened to the base, the first sliding groove and the second sliding groove are combined to form the sliding groove.

[0020] A partition is disposed in the middle of the base, and the middle part of the third transmission rod is connected to the partition through a third rotating shaft. The partition can separate the first transmission rod and the second transmission rod.

[0021] Optionally, the connector and the base are integrally formed, the connector is cylindrical, and the connector has mounting holes along the circumference.

[0022] Optionally, the sides of the base and the top cover are respectively provided with multiple grooves.

[0033] Preferred embodiments of the invention will now be described in more detail. While preferred embodiments of the invention are described below, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0034] This invention provides a switch handle with dual touch functionality, comprising:

[0035] The fixed component is connected to the passive arm at one end, and a sliding groove is opened inside the other end of the fixed component;

[0036] The transmission assembly is movably disposed in the slide. The transmission assembly includes a spring and an operating part. The part of the transmission assembly that extends from the other end of the fixed assembly is the operating part. The spring can cause the transmission assembly to extend towards the other end of the fixed assembly.

[0037] The touch arm is connected to the other end of the transmission assembly. When the operating part is pressed into the fixed assembly, the transmission assembly drives the touch arm to contact the unlock button of the robotic arm.

[0038] Specifically, the switch handle is fixedly connected to the passive arm via a fixing component, and a transmission component is installed in a groove within the fixing component. When the operating part is pressed, the transmission component moves the touch arm, causing it to contact the unlock button on the robotic arm and apply force, thus unlocking the robotic arm. When the operating part is released, the transmission component, under the action of an internal spring, moves the operating part out of the fixing component, causing the touch arm to move away from the unlock button, thus locking the robotic arm. This switch handle, with its simple structure, allows for unlocking and locking of the robotic arm by pressing or releasing the operating part, preventing accidental movement of the robotic arm and reducing risks during surgery.

[0039] Optionally, the transmission assembly includes:

[0040] The first transmission rod has an operating part at one end and a first rotating shaft in the middle.

[0041] The second transmission rod has one end connected to the inner wall of the slide groove via a spring, and a second rotating shaft is provided in the middle of the second transmission rod;

[0042] The third transmission rod is rotatably mounted in the slide groove. Long slots are opened at both ends of the third transmission rod, and the long slots slide with the first rotating shaft and the second rotating shaft respectively.

[0043] The second transmission rod moves in the opposite direction to the first transmission rod.

[0044] Specifically, the transmission assembly includes a first transmission rod and a second transmission rod that move relative to each other, and the two transmission rods are connected by a third transmission rod. One end of the first transmission rod with an operating part extends from the fixed assembly, indicating that the robotic arm is in a locked state. When it is necessary to unlock the robotic arm during surgery, the operating part is pressed, and the first transmission rod moves in a first direction. Since the middle part of the third transmission rod is rotatably connected to the slide, both ends of the third transmission rod will rotate and move in opposite directions. Under the action of the third transmission rod, the second transmission rod moves in a second direction. The first and second directions are opposite to each other, ultimately enabling the second transmission rod to drive the touch arm to press the unlock button of the robotic arm, and the robotic arm switches to the unlocked state.

[0045] Optionally, the other end of the first transmission rod extends to the outside of the fixed assembly. A limit rod is provided at the other end of the first transmission rod. The limit rod is perpendicularly connected to the first transmission rod. Under the action of the spring, when the operating part extends out of the fixed assembly, the limit rod abuts against the other end of the second transmission rod.

[0046] Specifically, a limit rod is provided at the other end of the first transmission rod. Since the first and second transmission rods are connected by a third transmission rod, the distance between the first and second transmission rods will not be too large. The limit rod connected to the first transmission rod can touch the end of the second transmission rod during the relative sliding process. When the operating part is not pressed, the spring will drive the second transmission rod to move towards the touch arm. Under the transmission of the third transmission rod, the first transmission rod moves in the opposite direction. In this way, when the operating part extends out of the fixed assembly, the limit rod and the end of the second transmission rod limit each other, and the first transmission rod will no longer extend out of the fixed assembly. In this way, there is still a connection between the spring and the second transmission rod, ensuring the accurate position of each part in the switch handle.

[0047] Optionally, the elongated hole is provided along the length direction of the third transmission rod.

[0048] Specifically, when the second transmission rod is rotated, the shafts on the two transmission rods slide in the elongated hole, allowing the transmission assembly to operate normally.

[0049] Optionally, the operating part is a button, and the end of the button is set as a rounded surface.

[0050] Specifically, a button is fitted onto the end of the first transmission rod, which forms the operating part. The outer surface of the button is made into an arc surface to facilitate pressing the operating part.

[0051] Optionally, the fixing components include:

[0052] Connector for connection to the passive arm;

[0053] The base is connected to the connector at one end, and a first sliding groove is provided on the base.

[0054] The top cover is detachably connected to the base. A second sliding groove is provided on the top cover. When the top cover is fastened to the base, the first sliding groove and the second sliding groove are combined to form a sliding groove.

[0055] A partition is located in the middle of the base. The middle part of the third transmission rod is connected to the partition through a third rotating shaft. The partition can separate the first transmission rod and the second transmission rod.

[0056] Specifically, the fixing component mainly consists of a base and a top cover that are fastened together, forming a sliding groove between the base and the top cover. A partition is set in the sliding groove to separate the first and second transmission rods. A third transmission rod is rotatably mounted on the partition. When the first or second transmission rod is subjected to force, it will drive the other transmission rod to move in the opposite direction through the third transmission rod. The base and the top cover are also provided with semi-circular openings at both ends. After the sliding groove is formed, both ends of the first transmission rod and the end of the second transmission rod connected to the touch arm can extend out from the assembled circular openings, leaving sufficient space for the transmission rods to move.

[0057] Optionally, the connector and the base are integrally formed, the connector is cylindrical, and the connector has mounting holes along the circumference.

[0058] Specifically, the fixed component is connected to the passive arm via a connector. To improve the connection strength between the switch handle and the surgical robot, the connector and the base are designed as an integrated structure.

[0059] Optionally, the sides of the base and the top cover are respectively provided with multiple grooves.

[0060] Specifically, after the base and the top cover are fastened together, the multiple grooves on the base and the top cover are connected to each other, which makes it easy for the hand to grasp the outer surface of the fixing component and press the operating part with the fingers, thus ensuring the accuracy of operation and avoiding slippage.

[0061] Optionally, the touch arm is C-shaped, with one end connected to the other end of the second transmission rod, and the other end of the touch arm corresponding to the unlock button of the robotic arm.

[0062] Specifically, the touch arm is C-shaped. When the touch arm is moved by the second transmission rod, the other end of the touch arm can press the unlock button of the robotic arm without touching other parts of the surgical robot.

[0063] Optionally, both the first and second transmission rods have non-circular cross-sections.

[0064] Specifically, the first and second transmission rods can only be linked through the third transmission rod if they do not rotate radially within the slide groove. The first and second transmission rods are square and triangular, respectively, inserted into the fixed assembly, and the transmission rods will not rotate.

[0065] Example

[0066] like Figures 1 to 3 As shown, the present invention provides a switch handle with dual touch function, comprising:

[0067] The fixed component is connected to the passive arm at one end, and a sliding groove is opened inside the other end of the fixed component;

[0068] The transmission assembly is movably disposed in the slide groove. The transmission assembly includes a spring 1 and an operating part 2. The part of the transmission assembly that extends from the other end of the fixed assembly is the operating part 2. The spring 1 can cause the transmission assembly to extend towards the other end of the fixed assembly.

[0069] The touch arm 3 is connected to the other end of the transmission assembly. When the operating part 2 is pressed into the fixed assembly, the transmission assembly drives the touch arm 3 to contact the unlock button of the robotic arm.

[0070] In this embodiment, the transmission assembly includes:

[0071] The first transmission rod 4 has an operating part 1 at one end and a first rotating shaft 7 in the middle.

[0072] The second transmission rod 5 has one end connected to the inner wall of the slide groove via a spring 1, and a second rotating shaft 8 is provided in the middle of the second transmission rod 5.

[0073] The third transmission rod 6 is rotatably mounted in the slide groove. The two ends of the third transmission rod 6 are respectively provided with elongated holes 9, which are slidably engaged with the first rotating shaft 7 and the second rotating shaft 8 respectively.

[0074] The second transmission rod 5 moves in the opposite direction to the first transmission rod 4.

[0075] In this embodiment, the other end of the first transmission rod 4 extends to the outside of the fixed assembly. The other end of the first transmission rod 4 is provided with a limiting rod 10, which is perpendicularly connected to the first transmission rod 4. Under the action of the spring 1, when the operating part 2 extends out from the fixed assembly, the limiting rod 10 abuts against the other end of the second transmission rod 5.

[0076] In this embodiment, the elongated hole 9 is provided along the length direction of the third transmission rod 6.

[0077] In this embodiment, the operation part 1 is a button, and the end of the button is set as an arc surface.

[0078] In this embodiment, the fixing component includes:

[0079] Connector 11 is used for connection with the passive arm;

[0080] The base 12 is connected to the connector 11 at one end, and the base 12 is provided with a first sliding groove 13.

[0081] The upper cover 16 is detachably connected to the base 12. The upper cover 16 has a second sliding groove. When the upper cover 16 is fastened to the base 12, the first sliding groove 13 and the second sliding groove are combined to form a sliding groove.

[0082] The partition 14 is located in the middle of the base 12. The middle part of the third transmission rod 6 is connected to the partition 14 through the third rotating shaft 15. The partition 14 can separate the first transmission rod 4 and the second transmission rod 5.

[0083] In this embodiment, the connector 11 and the base 12 are integrally formed. The connector 11 is cylindrical and has mounting holes along its circumference.

[0084] In this embodiment, the sides of the base 12 and the top cover 16 are respectively provided with a plurality of grooves 15.

[0085] In this embodiment, the touch arm 3 is C-shaped, with one end of the touch arm 3 connected to the other end of the second transmission rod 5, and the other end of the touch arm 3 corresponding to the unlock button of the robotic arm.

[0086] In this embodiment, the cross-sections of the first transmission rod 4 and the second transmission rod 5 are both non-circular.

[0087] In summary, during use, the switch handle with dual touch function is fixed to the passive arm via connector 11. When the robotic arm needs to be unlocked, the operator holds the outside of the fixed component and presses the operating part 2. The first transmission rod 4 slides in the first slide groove 13, driving the third transmission rod 6 to rotate around the third spindle 15 via the first rotating shaft 7. The third transmission rod 6 drives the second transmission component 5 to slide in the first slide groove 13 via the second rotating shaft 8, and compresses the spring 1. At this time, the first transmission rod 4 and the second transmission rod 5 move in opposite directions, triggering the unlock button via connector 11, thus unlocking the robotic arm. When the robotic arm needs to be locked, the operator releases the operating part 2. The second transmission rod 5 resets under the influence of the elastic potential energy of the spring 1, and the first transmission rod 4 and the second transmission rod 5 move in opposite directions. Connector 11 separates from the unlock button, and the robotic arm returns to the locked state.

[0088] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
