Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of continuum robots, and particularly relates to a structure type layout spiral muscle tendon continuum robot and a use method. BACKGROUND

[0002] With the rapid progress of modern science and technology, the application of continuum robots in multiple key fields, especially in medical surgery, precision industrial detection and disaster rescue, is increasingly highlighting its irreplaceable value. Such robots, with their excellent flexibility, high environmental adaptability and flexible movement in complex spaces, have become a powerful tool to solve the problems of high precision requirement in minimally invasive surgical operation, narrow and non-structured environment detection difficulty, etc. However, although continuum robots have shown great application potential in these fields, their existing technical framework and design concept still face many challenges and limitations, hindering their further expansion to more complex and high-precision task fields.

[0003] The core of the continuum robot is its unique driving and transmission mechanism, i.e. relying on the tendon system to realize the bending, twisting and other complex actions of the robot body. This mechanism, to some extent, endows the robot with flexible movement characteristics, but the tendon layout and guide structure design under the existing technology is relatively simple and fixed. Most continuum robots adopt a relatively simple tendon driving mode, in which the path and guide structure of the tendon are often limited to a specific geometric shape, such as a straight line or a simple curve, which makes the robot appear inadequate when facing tasks that require multi-dimensional, multi-angle bending deformation to adapt to complex spatial structures. Especially in medical minimally invasive surgery, for the precise control of surgical instruments to explore and operate complex paths in the human body, the existing tendon layout is difficult to meet the dual requirements of flexibility and precision of the robot by the surgeon. In addition, in the application scenarios of disaster rescue and industrial detection, the exploration of narrow space and the adaptability of non-structured environment also pose higher challenges to the structural design of continuum robots, and the limitations of the existing tendon guide structure undoubtedly limit the application potential of robots in these fields.

[0004] The design and control precision of tendon tensioning devices is another pressing issue. During the operation of a continuum robot, stable tendon tension is crucial for ensuring the robot's motion accuracy and stability. However, traditional tendon tensioning devices have significant shortcomings in adjustment. The adjustment process is cumbersome and difficult to achieve precise quantitative control, leading to gradual relaxation of the tendons due to fatigue and wear after prolonged continuous operation, directly affecting the robot's control accuracy and motion performance. Especially in medical surgery, even minor control errors can lead to unpredictable risks. Existing tendon guiding and tensioning devices also present significant challenges in structural adjustment. Due to design limitations, adjusting the tendon layout or tension often requires disassembling the entire tendon system. This is not only complex and time-consuming but can also damage the tendons and guiding structures, severely impacting work efficiency and the robot's lifespan. Especially in emergency rescue missions or industrial inspection tasks requiring frequent changes in working environment, this complexity of structural adjustment undoubtedly becomes a major obstacle to the application of continuum robots.

[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] The structural layout spiral tendon continuum robot provided by the present application solves the limitations of tendon continuum robots in tendon layout, tension adjustment and structure adjustment in the prior art, thereby greatly improving the flexibility and control accuracy of the robot when performing complex tasks. Specifically, the structural spiral guide tendon spacing disc used by the robot not only breaks the single nature of traditional tendon layout, but also realizes the multidimensional and spiral distribution of the tendon on the continuum backbone. This layout method not only optimizes the path planning of the tendon and reduces the mutual interference between the tendons, but also significantly enhances the structural strength and stability of the robot. The design of each spacing disc is precisely calculated to ensure that the tendon can evenly distribute stress when bearing load, avoiding performance degradation or damage of the robot caused by local overload, and providing a solid foundation for the robot to perform high-precision and high-load operations.

[0021] Further, the combination of the continuum backbone and the continuum guide bone constructs a flexible and stable motion framework. The continuum backbone, as the main support structure of the robot, considers the balance between lightweight and high strength in material selection and structure design, ensuring the rapid response capability and endurance capability of the robot in complex spatial environments. The design of the continuum guide bone precisely controls its length, bending angle and material elasticity, realizes accurate guidance and support of the tendon path, and effectively improves the efficiency and accuracy of tendon transmission. This design not only simplifies the complexity of traditional robot structure adjustment, but also enables the robot to quickly and flexibly adjust its posture to adapt to changing working environments when facing different working demands.

[0022] Further, the tendon adjustable tension device introduced by the present application is the key to improving the motion performance and control accuracy of the robot. Through the built-in high-precision sensor and intelligent algorithm, the device can monitor the tension state of the tendon in real time and automatically adjust according to the preset parameters or real-time feedback data, ensuring that the tendon is always in the best working state. Not only does it solve the problem of tendon tension adjustment, but it also significantly improves the stability and reliability of tendon transmission, reduces motion errors caused by tendon relaxation or excessive tension, and enables the robot to control the motion trajectory and force of each joint more accurately when performing precise operations or complex actions, thereby greatly improving the quality and efficiency of the work. In addition, the introduction of the tendon winding transmission module, which uses advanced winding technology and precise transmission mechanisms, realizes efficient and stable transmission of the tendon. At the same time, its modular design makes maintenance and upgrading more convenient, and can flexibly adjust the transmission ratio or replace tendons of different specifications according to actual needs to adapt to different work scenarios and load requirements. This high degree of flexibility and scalability makes the robot proposed by the present application not only suitable for current work tasks, but also has good future adaptability, and can continue to upgrade as technology continues to advance, meeting more diverse and higher-level work requirements.

DETAILED DESCRIPTION

[0042] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the present application will be clearly and completely described below in combination with the drawings in the present application, and the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing specific embodiments only and is not intended to be limiting of the application. The use herein of the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0044] In view of the single tendon layout, difficult tendon tension adjustment and complex structure adjustment of the tendon continuum robot in the prior art, which limits the flexibility and control accuracy of the tendon continuum robot in complex tasks, the present application provides a structural layout spiral tendon continuum robot.

[0045] As shown in Figure 1 The structural layout spiral tendon continuum robot of the present application comprises a structural spiral guide tendon spacing disc 10, a continuum backbone 20, a continuum guide bone 30, a robot structure box 40, a tendon adjustable tension device 50, a tendon winding transmission module 60 and a driving module 70.

[0046] The structural spiral guide tendon spacing disc 10 is installed on the continuum backbone 20 to form an actuator of the structural layout spiral tendon continuum robot. The other end of the continuum backbone 20 is installed on one end of the continuum guide bone 30, and the other end of the continuum guide bone 30 is installed on the robot structure box 40 to constitute the overall appearance of the structural layout spiral tendon continuum robot 1. The tendon adjustable tension device 50, the tendon winding transmission module 60 and the driving module 70 are placed inside the robot structure box 40. The driving module 70 is used to drive the tendon winding transmission module 60 to move.

[0047] As shown in Figure 2 The tendon adjustable tension device 50 is placed in the internal area of the robot structure box 40 close to the continuum guide bone 30, and the tendon winding transmission module 60 and the driving module 70 are placed in the internal area of the robot structure box 40 away from the continuum guide bone 30.

[0048] As shown in Figure 3As shown, the continuum backbone 20, the continuum guide bone 30, the tendon adjustable tension device 50 and the tendon winding transmission module 60 are located on the same center line.

[0049] The tendon is installed on the structural layout spiral tendon continuum robot 1, and sequentially passes through the structural spiral guide tendon interval disc 10, the continuum guide bone 30, the robot structural box 40, the tendon adjustable tension device 50, and finally is connected to the tendon winding transmission module 60. Under the action of the driving module 70, the tendon winding transmission module 60 starts to pull the tendon, and the tendon passes through the tendon adjustable tension device 50, the robot structural box 40 and the continuum guide bone 30. Through the structural spiral guide tendon interval disc 10 with different layouts, the force is transmitted to the continuum backbone 20, so that different configurations are realized in specific tasks.

[0050] When the structural layout spiral tendon continuum robot 1 performs a complex task, the tendon may be relaxed due to long-time work, so it is necessary to detect the tension of the tendon or tension the tendon through the tendon adjustable tension device 50 during the execution of a new task or a task.

[0051] Therefore, the structural layout spiral tendon continuum robot can perform deep cavity operation tasks, such as minimally invasive surgery and detection in a narrow and congested unstructured environment. Since the tendon tension device is improved, the stability of the tendon is ensured, the movement ability of the continuum robot in a complex spatial environment is enhanced, and the control precision is improved.

[0052] The structural spiral guide tendon interval disc 10 of the present application can realize the spiral layout of the tendon of the structural layout spiral tendon continuum robot 1 without disassembling the tendon. Figure 4 As shown, the structural spiral guide tendon interval disc 10 comprises an adjustable structural spiral guide tendon interval disc fixing seat 101 and a structural guide tendon spiral interval disc 102.

[0053] The adjustable structural spiral guide tendon interval disc fixing seat 101 comprises a special-shaped pin hole 1011, an interval disc fixing seat front surface 1012, an installation inner surface groove 1013 and an open wire groove 1014.

[0054] The structural guide tendon spiral interval disc 102 is installed on the adjustable structural spiral guide tendon interval disc fixing seat 101, and the special-shaped pin hole 1011 of the adjustable structural spiral guide tendon interval disc fixing seat 101 and the installation hole 1021 of the structural guide tendon spiral interval disc 102 are located on the same center axis.

[0055] As shown, Figure 5As shown, the adjustable structural spiral guide tendon interval disc fixing seat 101 is circular, and a plurality of same-direction equidistant open wire grooves 1014 are arranged in the peripheral area of the circle. The center area of the adjustable structural spiral guide tendon interval disc fixing seat 101 is provided with a special-shaped pin hole 1011, and the front surface 1012 of the interval disc fixing seat is a horizontal smooth surface. The back surface of the interval disc fixing seat opposite to the front surface 1012 is provided with a mounting inner surface groove 1013, and the center point of the mounting inner surface groove 1013 and the special-shaped pin hole 1011 are located on the same center axis. The mounting inner surface groove 1013 includes a first square groove 10131 and a second square groove 10132.

[0056] The first square groove 10131 and the second square groove 10132 are arranged in the back surface of the interval disc fixing seat in mutual superposition. The first square groove 10131 and the second square groove 10132 are consistent in size, and the center points thereof and the special-shaped pin hole 1011 are located on the same center axis.

[0057] As shown, Figure 6 The structural guide tendon spiral interval disc 102 includes a mounting hole 1021, a tendon guide hole 1024 and a hexahedron 1025.

[0058] The center area of the structural guide tendon spiral interval disc 102 is the hexahedron 1025, a plurality of same-direction equidistant tendon guide holes 1024 are arranged on the four sides of the hexahedron 1025, and the mounting hole 1021 is arranged in the center area of the hexahedron 1025. As shown, Figure 6 (a), the outer side surface 1023 of the structural guide tendon spiral interval disc 102 is a plane, and the same bottom surface of the hexahedron 1025 and the tendon guide hole 1024 is located in the same horizontal plane; as shown, Figure 6 (b), the inner side surface of the structural guide tendon spiral interval disc 102, the hexahedron 1025 is higher than the tendon guide hole 1024, forming an inner side surface square convex groove 1022.

[0059] As shown, Figure 7 The structural guide tendon spiral interval disc 102 is mounted on the adjustable structural spiral guide tendon interval disc fixing seat 101, the special-shaped pin hole 1011 and the mounting hole 1021 are aligned, and the inner side surface square convex groove 1022 in the structural guide tendon spiral interval disc 102 is mounted in the square groove of the adjustable structural spiral guide tendon interval disc fixing seat 101.

[0060] When the first square groove 10131 of the mounting inner surface groove 1013 is selected, at this time, the special-shaped pin hole 1011 of the adjustable structural spiral guide tendon interval disc fixing seat 101 and the mounting hole 1021 of the structural guide tendon spiral interval disc 102 in the structural spiral guide tendon interval disc 10 are aligned, forming a circular hole.

[0061] When the second square slot 10132 of the installation inner surface groove 1013 is selected, at this time, the special-shaped pin hole 1011 of the adjustable special-shaped spiral guide tendon interval disc fixing seat 101 and the installation hole 1021 of the special-shaped guide tendon spiral interval disc 102 in the special-shaped spiral guide tendon interval disc 10 are aligned to form a long slot.

[0062] As shown in Figure 8 In order to perform more complex space tasks, the number of square slots in the installation inner surface groove 1013 can be increased until the Nth square slot 10137, and when the state of the tendon winding needs to be adjusted, the special-shaped guide tendon spiral interval disc 102 is installed in different sub-square slots in the installation inner surface groove 1013 to form the required hole under the set condition. By alternately installing the special-shaped guide tendon spiral interval disc 102 in different square slots, various spiral changes of the tendon path can be achieved.

[0063] A plurality of special-shaped spiral guide tendon interval discs 10 are installed on the continuum backbone 20, and the tendon in a spiral layout can make the continuum backbone 20 realize complex spatial bending deformation.

[0064] It should be clear that the shapes of the square slots and the corresponding inner square protruding grooves in the present application correspond, and are not limited to square shapes.
