Embodiment Construction

[0085] In order to make the purpose, advantages and features of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are all in very simplified form and not drawn to scale, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention. In addition, the structures shown in the drawings are often a part of the actual structures. In particular, each drawing needs to display different emphases, and sometimes uses different scales.

[0086]As used in this specification, the singular forms "a", "an" and "the" include plural referents unless the content clearly dictates otherwise. As used in this specification, the term "or" is usually used in the sense of including "and / or", unless the content clearly indicates otherwise, the term "proximal end" is usually the end close to the...

Abstract

The invention provides a wire transmission structure, a surgical instrument and a surgical robot. The wire transmission structure comprises a base, a first driving shaft, a second driving shaft, a third driving shaft, a first traction body group, a second traction body group, a wobble wheel, a third guide part and a fourth guide part, wherein the base is provided with a symmetric surface; and each traction body group comprises two traction bodies connected to one driving shaft, and the two traction bodies corresponding to the traction bodies can be driven to move in opposite directions through rotation of the driving shafts, so the traction bodies are used for driving one joint of an instrument tail end assembly to move respectively. Furthermore, the first traction body group and the second traction body group are respectively used as a whole and can move in opposite directions under the action of two guide pieces on the wobble wheel, so a third joint of the instrument tail end assembly is driven to move. Therefore, the three joints of the instrument tail end assembly are driven by the four traction bodies to move; and a transmission structure is simple, occupied space is small, and transmission efficiency can be improved.

Description

technical field [0001] The invention relates to the field of surgical instruments, in particular to a wire transmission structure, a surgical instrument and a surgical robot. Background technique [0002] In recent years, with the application and development of robot-related technologies, especially the development of computing technology, the role of medical surgical robots in clinical practice has attracted more and more attention. Among them, the minimally invasive surgical robot system can reduce the physical labor of doctors during the operation through interventional therapy, and at the same time achieve the purpose of precise surgery, so that patients have less trauma, less blood loss, less postoperative infection, and faster postoperative recovery. The design of surgical instruments for surgical robots directly determines the success or failure of the minimally invasive surgical robot system, and the performance of surgical instruments is a key factor affecting the p...
