Problems solved by technology

When multiple independent turning motions are connected in series through this structure, it is generally necessary to install a drive unit (such as a motor, hydraulic ejector, etc.) The load of the end drive unit will make the realization structure of this function relatively complicated and relatively large in size

Embodiment 1

[0067] figure 1 A perspective view showing the first embodiment of the flexible continuum mechanical structure according to the present invention. like figure 1 , the flexible continuum mechanical structure 100 is composed of a distal structure body 1 , a middle connecting body 2 and a proximal structure body 3 . The distal structure 1 includes a distal locking disc 4, a distal spacer 5 and a structural bone 6, the middle connecting body 2 includes pipe fixing plates 7, 9 and a pipe 8, and the proximal structure 3 includes a proximal spacer 10, The proximal locking disc 11 and the structural bone 6. In this embodiment, the structural bone 6 on the distal structure 1 and the corresponding structural bone 6 on the proximal structure are the same structural bone, but those skilled in the art should understand that the structure on the distal structure 1 The bone and the corresponding structural bone 6 on the proximal structural body may also be not the same structural bone, bu...

Embodiment 2

[0080] Figure 10 A structural diagram showing the second embodiment of the flexible continuum mechanical structure according to the present invention. In this embodiment, the flexible continuum mechanical structure can be sequentially extended to form a multi-segment continuum mechanical structure, that is, a multi-segment proximal structure and / or a multi-segment distal structure can be sequentially extended. Figure 10 The embodiment shown in is extended with two proximal structure bodies and two distal structure bodies, which share a central connecting body. Among them, the basic structure of each proximal structure, distal structure, and middle connector figure 1 The illustrated embodiment is the same and will not be described in detail here.

[0081] like Figure 10 As shown, the No. 1 proximal structure 3 and the No. 1 distal structure 1 constitute the No. 1 continuum mechanical structure, while the No. 2 proximal structure 19 and the No. 2 distal structure 18 consti...

Abstract

The invention relates to a flexible continuous body mechanical structure capable of bending and stretching. The continuous body mechanical structure comprises a far-end structure body, a near-end structure body and a middle connection body. The far-end structure body comprises far-end interval plate, a far-end locking plate and a structural framework. The near-end structure body comprises a near-end interval plate, a near-end locking plate and a structural framework. The middle connection body comprises a pipeline fixing board and a pipeline. The far-end structure body is connected with the near-end structure body through the middle connection body, one end of the structural framework of the near-end structure body is fixed on the near-end locking plate, and the structural framework of the near-end structure body penetrates through the near-end interval plate, the middle connection body and the far-end interval plate in sequence and is fixed on the far-end locking plate. Therefore, when the near-end structure body is driven to bend and/ or stretch towards any direction, the far-end structure body correspondingly bends and/ or stretches towards opposite direction. By means of a very simple structure of the continuous body mechanical structure, the purpose of bending and/ or stretching towards any direction is achieved. The continuous body mechanical structure has very wide purposes.

Description

technical field [0001] The invention relates to the fields of medical equipment, industrial automation and the like, in particular to a bendable and stretchable flexible continuum mechanical structure used for medical equipment, industrial automation equipment and the like. Background technique [0002] In the existing bendable mechanical structure, the controllable bending motion is basically realized by the relative rotation at the hinge joint through two rigid or flexible links hinged to each other. When multiple independent turning motions are connected in series through this structure, it is generally necessary to install a drive unit (such as a motor, hydraulic ejector, etc.) The load of the end drive unit will make the realization of this function relatively complicated in structure and relatively large in size. [0003] In medical operations or industrial deep cavity detection, etc., it is necessary to construct instruments with multiple degrees of freedom and multi...
