Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0032] It should be noted that when a component is said to be "mounted on" another component, it may be directly mounted on another component or there may be an intervening component. When a component is said to be "set on" another component, it may be set directly on the other component or there may be an intervening component at the same time. When a component is said to be "fixed" to another component, it may be directly fixed to the other component or ther...

Abstract

The invention provides an operation mechanical arm. The operation mechanical arm comprises a preoperative positioning assembly, an execution assembly and a telecentric control assembly arranged between the preoperative positioning assembly and the execution assembly; the execution assembly comprises an execution rod and an operation instrument arranged at one end, which is relatively far away fromthe telecentric control assembly, of the execution rod; the telecentric control assembly is provided with a rotation driving piece and a sensor; the rotation driving piece is connected with one end,which is relatively close to the telecentric control assembly, of the execution rod and can drive the execution rod and the operation instrument to synchronously rotate along the axial direction of the execution rod; the sensor is connected with the telecentric control assembly, and the sensor and the operation instrument do not synchronously rotate along the axial direction of the execution rod;and the sensor is used for detecting environmental force and/or environmental moment applied to the operation instrument. According to the operation mechanical arm provided by the invention, the sensor and the surgical instrument are designed to be a structure without synchronous rotation along the axial direction of the execution rod, so that the sensor can be installed in a relatively stable installation environment, and the measurement precision of the sensor is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical robot arm and a surgical robot. Background technique [0002] The birth of minimally invasive surgery largely overcomes the shortcomings of traditional surgery such as large incision, large amount of bleeding, many complications and high surgical risk. Due to the rapid development in recent years, minimally invasive surgery is gradually gaining the favor of medical staff and patients, and has become an emerging field of medical research and clinical application. [0003] Using surgical robots to assist doctors in minimally invasive surgery can make surgical operations more sensitive and precise. Take the da Vinci surgical robot as an example. The da Vinci surgical robot can magnify the doctor's field of view ten times while effectively filtering out the doctor's hand tremors. It has a wide range of clinical applications in the field of minimally invasive s...
