Embodiment Construction

[0031] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0032] Such as figure 1 As shown, the present invention provides a robot device for minimally invasive surgery, the manipulator includes a support mechanism 6, a drive mechanism, a control mechanism and a bending arm. Wherein, the drive mechanism includes a fourth drive mechanism 54, the fourth drive mechanism 54, the casing 61 and the end cover 62 are fixed in the support mechanism 6, the casing 61 is connected with the fourth drive mechanism 54 through a gear (not shown), the second The four driving mechanisms 54 drive the casing 61 and the bending arm to rotate together.

[0033] Such as figure 2 As shown, the end cap 62 is detachably connected to the outer shell 61, so that the inner core connected to the bending arm can be inserted and removed conveniently. The inner core includes a transmi...

Abstract

The invention belongs to the technical field of operation robots, and discloses a minimally-invasive operation robot device. The minimally-invasive operation robot device comprises bent arms and a driving mechanism, the bent arms comprise the first bent arm and the second bent arm, the first bent arm is provided with a first elastic unit, and a first connecting part of a stationary clamp is arranged at the top of the first elastic unit and connected with a first push-pull rod; the second bent arm is provided with a second elastic unit, a second connecting part is arranged between the first elastic unit and the second elastic unit and connected with a second push-pull rod, and the first push-pull rod penetrates into the second connecting part and is connected with the first connecting part.According to the minimally-invasive operation robot device, the driving mechanism is connected with the first push-pull rod and the second push-pull rod separately to be used for driving the first push-pull rod and the second push-pull rod to perform pushing and pulling to control the first elastic unit and the second elastic unit to be bent, and therefore the large bending angle of the bending arms is realized.

Description

technical field [0001] The invention relates to the technical field of surgical robots, in particular to a minimally invasive surgical robot device. Background technique [0002] Minimally invasive surgery refers to the operation performed on the human body through a minimum small incision. It is also generally called interventional surgery. Robot-assisted minimally invasive surgery uses various visual image equipment and advanced and dexterous surgical instruments to enter the human body through a small incision. The human body for treatment or diagnosis. [0003] The invention patent with the patent application number CN201710100601.3 discloses a minimally invasive manipulator structure, using the outer flexible shaft and the inner flexible shaft that are nested in each other, it can realize three kinds of actions of the manipulator. When the structure pulls the outer flexible shaft and the inner flexible shaft, the outer end of the arm body can be bent by pulling force; ...
