Description
Technical Field
The invention relates to a continuum structure, in particular to a flexible continuum structure capable of being driven integrally and a flexible mechanical arm comprising the flexible continuum structure.
Background
The existing continuum structure generally carries out direct push-pull to the driving wire in the continuum structure through the driving mechanism, and the driving to the driving wire is divided into two types: the first is to directly push and pull the driving wire through a linear pair, and drive the flexible mechanical arm to bend from the moment; the second is to push and pull a group of thicker driving wires through the linear pair first, so that the proximal continuum is bent, and a group of thinner driving wires on the proximal continuum are driven to bend, so as to drive the flexible mechanical arm to bend, and further, more driving wires are driven by a smaller number of driving mechanisms.
However, since the two driving modes are both direct push-pull driving wires for movement, when the number of the driving wires is large, the number of the driving mechanisms is correspondingly increased, so that the structure is complex.
Disclosure of Invention
In view of the above problems, one of the objects of the present invention is to provide a flexible continuous structure capable of being integrally driven, avoiding direct push-pull of driving wires, being not limited by the number of drivers when driving a large number of driving wires, and satisfying the bending performance of the flexible continuous structure, while having compact structure, simple principle, easy implementation and high reliability; it is another object of the present invention to provide a flexible robotic arm incorporating the flexible continuum structure.
In order to achieve the above purpose, the present invention adopts the following technical scheme: an integrally drivable flexible continuum structure comprising a proximal continuum and a distal continuum; wherein the proximal continuum comprises: the proximal end disk, the first proximal end stop disk and the second proximal end stop disk are arranged at intervals; the proximal ends of the first structural bones are fixedly connected with the second proximal end stop disc, and the distal ends of the first structural bones penetrate through the first proximal end stop disc and are fixedly connected with the proximal end stop disc; the distal continuum includes: the distal end base plate and the distal end stop plate are arranged at intervals, and the distal end base plate is adjacent to the proximal end base plate; the proximal ends of the second structural bones are fixedly connected with the first proximal end stopping disc, and the distal ends of the second structural bones penetrate through the proximal end stopping disc and the distal end stopping disc and are fixedly connected with the distal end stopping disc.

alternatively, one end of the drive connection portion is movably connected to the second proximal end stop so that the drive connection portion and the second proximal end stop can slide and/or rotate up and down relative to each other.
The flexible continuous body structure preferably further comprises a structural bone guiding tube bundle connected between the proximal disc and the distal disc, and the distal ends of the second structural bones are fixedly connected with the distal stop disc after sequentially passing through the proximal disc, the structural bone guiding tube bundle and the distal disc.
In the flexible continuous body structure, preferably, the driving connection part is a columnar sliding pin, at this time, the sliding pin is connected with the second proximal end stop disc by adopting a cylindrical pair through a guide hole arranged on the second proximal end stop disc, and the sliding pin can rotate around an axis and slide up and down along the guide hole on the second proximal end stop disc;
or the driving connecting part is annular, sleeved on the periphery of the second proximal end stop disc and can slide up and down and rotate relative to the second proximal end stop disc.
The flexible continuum structure, preferably, the proximal continuum further comprises at least one first proximal retention disk disposed between the first proximal stop disk and the second proximal stop disk and/or at least one second proximal retention disk disposed between the proximal disk and the first proximal stop disk, each of the first structural bones passing through the first proximal retention disk.

Compared with the traditional rigid kinematic chain which realizes bending motion by mutual rotation at joints, the flexible continuum structure realizes the bending deformation of the far-end structure through the deformation of the near-end structure, and the structural main body of the flexible continuum structure simultaneously becomes a driving transmission structure, so that extremely high degree of freedom configuration can be realized in a small-size space range, and the flexible continuum structure can be widely applied to the development of medical instruments such as flexible operation arms, endoscopes, controllable catheters and the like, and novel special equipment such as industrial deep-cavity detection endoscopes, flexible mechanical arms and the like.

Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the attached drawings, so that the objects, features and advantages of the present invention will be more clearly understood. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the invention, but rather are merely illustrative of the true spirit of the invention.
In the description of the present invention, it should be understood that the terms "proximal," "distal," "upper," "lower," "inner," "outer," and the like indicate orientations or positional relationships based on the orientations or positional relationships illustrated in the drawings, and are merely used for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements being referred to must have a specific orientation, be configured and operated in a specific orientation, and therefore should not be construed as limiting the scope of the present invention. In the present invention, when referring to "distal or distal," the term refers to a side or end that is relatively far from the operator. When referring to "proximal or proximal," the term refers to a side or end that is relatively close to the operator.
As shown in fig. 1, the integrally drivable flexible continuous body structure provided in this embodiment includes a proximal continuous body 1 and a distal continuous body 3.
Wherein the proximal continuum 1 comprises: the proximal end disk 4, the first proximal end stop disk 7 and the second proximal end stop disk 8 are arranged at intervals; the first structural bones 13, the proximal ends of the first structural bones 13 are fixedly connected with the second proximal end stop disc 8, and the distal ends of the first structural bones 13 penetrate through the first proximal end stop disc 7 and are fixedly connected with the proximal end disc 4.
The distal continuum 3 includes: a distal end base plate 9 and a distal end stopper plate 11, which are arranged at intervals, and the distal end base plate 9 is adjacent to the proximal end base plate 4; and the proximal ends of the second structural bones 12 are fixedly connected with the first proximal end stop disc 7, and the distal ends of the second structural bones 12 penetrate through the proximal end disc 4 and the distal end base disc 9 and are fixedly connected with the distal end stop disc 11.
Thus, the proximal continuum 1 is associated with the distal continuum 3, and when a driving mechanism is applied to drive the proximal continuum 1 to generate bending motion, the distal continuum 3 is driven to generate bending motion opposite to the proximal continuum 1 in the bending state of the proximal continuum 1.
In the above embodiment, the flexible continuum structure preferably further comprises a drive connection 14 connected to the second proximal stop disc 8. In particular, one end of the drive connection 14 may be fixedly connected to the second proximal stop disc 8, while the drive connection 14 may be connected to the drive mechanism by rotation and/or displacement.
In the above embodiment, preferably, one end of the driving connection portion 14 is movably connected to the second proximal stopper 8, so that the driving connection portion 14 and the second proximal stopper 8 can slide and/or rotate up and down with respect to each other. Specifically, one end of the driving connection portion 14 is connected with the second proximal end stop disc 8 by a cylindrical pair, so that the driving connection portion 14 and the second proximal end stop disc 8 can slide and/or rotate relatively up and down, and the other end of the driving connection portion 14 passes through the second proximal end stop disc 8 to form a free end, and a driving mechanism is externally connected through the free end.
In the above embodiment, preferably, the flexible continuous body structure further includes a structural bone guiding tube bundle 2, the proximal end of the structural bone guiding tube bundle 2 is connected to the proximal disc 4, the distal end of the structural bone guiding tube bundle 2 is connected to the distal base disc 9, and the distal ends of the plurality of second structural bones 12 sequentially pass through the proximal disc 4, the structural bone guiding tube bundle 2 and the distal base disc 9 and then are fixedly connected to the distal stop disc 11. The function of the structural bone guide bundle 2 is to guide and constrain a second structural bone 12 located between the proximal disc 4 and the distal disc 9.
In operation, the flexible continuum structure provided in the above embodiment, because the proximal disc 4 is fixed, when a planar driving mechanism is applied to drive the free end of the connecting portion 14 to move in the same horizontal plane direction, the proximal disc 4 and the second proximal stop disc 8 are dislocated, and the axes of the two are no longer coincident. Because the two ends of the first structural bone 13 are respectively fixed with the proximal disc 4 and the second proximal stop disc 8, each first structural bone 13 is forced to bend, so that the proximal continuum 1 generates dual bending between the proximal end and the distal end; simultaneously, the first proximal end stop disc 7 is turned cooperatively, so that the second structural bones 12 with the ends fixed on the first proximal end stop disc 7 are pushed and pulled, the second structural bones 12 uniformly fixed on the first proximal end stop disc 7 are pulled on one side, so that the length of the corresponding second structural bones 12 in the proximal continuum 1 is increased, and the other side is pressed, so that the length of the corresponding second structural bones 12 in the proximal continuum 1 is reduced. However, the overall length of each second structural bone 12 is constant, and the length of each second structural bone 12 in the structural bone guide tube bundle 2 is constant, resulting in a corresponding change in the length of each second structural bone 12 in the distal continuum 1, thereby driving the distal continuum 3 to bend in opposite directions from the portion of the proximal continuum 1 adjacent the proximal disc 4. The bending ratio of the proximal continuum 1 and the distal continuum 3 is inversely proportional to the distribution radius of the corresponding second structural bone 12 in both (in this embodiment, the second structural bones 12 in the proximal continuum 1 and the distal continuum 3 are distributed circumferentially, which may be distributed circumferentially or in the matrix circumferential direction, may be uniformly distributed or non-uniformly distributed, and is not limited herein). The distribution radius of the second structural bone 12 in the proximal continuum 1 and the distal continuum 3 can be adjusted in application to meet the actual bending ratio requirement. Therefore, the second proximal end stop disc 8 and the driving connection part 14 are connected by adopting a cylindrical pair, so that the second proximal end stop disc 8 and the driving connection part 14 can slide up and down or rotate, parasitic movement (sliding up and down) in the axial direction generated during dual bending of the proximal end continuous body 1 and bending movement (rotation) in any direction can be met, the parasitic movement can avoid that the distal end continuous body 3 generates telescopic movement in the axial direction in the bending process, and the cover wrapping the periphery of the distal end continuous body 3 is wrinkled or overstretched, so that the service life of the cover is influenced.
In the above embodiment, the drive connection portion 14 may be preferably a columnar slide pin, in which case the slide pin is connected to the second proximal stopper 8 by a cylindrical pair through a guide hole provided in the second proximal stopper 8, and the slide pin is rotatable about an axis and slidable up and down along the guide hole in the second proximal stopper 8. Alternatively, the driving connection portion 14 may be annular and sleeved on the outer periphery of the second proximal end stop 8, and may slide and rotate up and down relative to the second proximal end stop 8.
In the above embodiment, preferably, the proximal continuum 1 further comprises at least one first proximal retention disc 6 arranged between the first proximal stop disc 7 and the second proximal stop disc 8 and/or at least one second proximal retention disc 5 arranged between the proximal disc 4 and the first proximal stop disc 7, each first structural bone 13 passing through the first proximal retention disc 6, the first proximal retention disc 6 being adapted to support the first structural bone 13 from the radial direction of the first structural bone 13 such that each first structural bone 13 remains parallel during bending deformation preventing the first structural bone 13 from destabilizing during bending movements.
In the above embodiment, preferably, the distal continuum 3 further comprises at least one distal holding disk 10 disposed between the distal disk 9 and the distal stopper disk 11, each second structural bone 12 passing through the second proximal holding disk 5 and the distal holding disk 10 in sequence, the second proximal holding disk 5 and the distal holding disk 10 serving to support the second structural bone 12 from the radial direction of the second structural bone 12, so that each second structural bone 12 remains in a parallel state during bending deformation, preventing the second structural bone 12 from being unstable during bending movement.
In the above embodiment, preferably, the first proximal holding disk 6, the first proximal stopper disk 7, the second proximal holding disk 5, the proximal disk 4, the distal base disk 9 and the distal holding disk 10 are circumferentially distributed with a plurality of through holes for sliding the first structural bone 13 and the second structural bone 12 therethrough, the proximal disk 4 and the second proximal stopper disk 8 are circumferentially distributed with a plurality of first locking holes for fixing the ends of the first structural bone 13, the first proximal stopper disk 7 and the distal stopper disk 11 are circumferentially distributed with a plurality of second locking holes for fixing the ends of the second structural bone 12, and the specific hole positions and hole numbers of the through holes and locking holes on the different disks depend on the distribution positions and numbers of the first structural bone 13 and the second structural bone 12.
In the above-described embodiments, preferably, pre-compressed elastic spacers (e.g., springs, not shown) may be installed between adjacent disks of the proximal continuum 1 and/or between adjacent disks of the distal continuum 3 to space the disks apart.
In the above embodiment, preferably, the first structural bone 13 and the second structural bone 12 may be made of an elastic thin rod or tube made of super elastic material, and generally may be made of a high-strength, high-toughness, elastic metal material such as nickel-titanium alloy; the structural bone guiding tube bundle 2 may be a steel tube bundle.
Based on the flexible continuous body structure provided by the embodiment, the invention also provides a flexible mechanical arm which comprises at least one flexible continuous body structure capable of being driven integrally.
Preferably, the flexible mechanical arm is formed by adopting two flexible continuous body structures in series or parallel connection, so that the flexibility of the arm body is improved.
