Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0019] As shown in the accompanying drawings, the flexible tool double drive mechanism of the surgical robot of the present invention includes a horizontal connecting plate 14, on which a first driving bracket 2 is fixedly installed, on the first driving bracket 2 Used for clamping and installing flexible tools (such as urethroscopes, catheters, etc.), the motor 1 is installed at one end of the horizontal connecting plate 14 through the motor connecting seat 19 . On the output shaft of the motor 1 is fixedly connected a first driving wheel 13 whose rotating shaft is arranged along the horizontal direction.

[0020] A second drive bracket 15 is fixedly installed on the other end of the horizontal connecting plate 14, and first guide wheels that can rotate around their respective shafts are installed in the horizontal direction through the shaft fr...

Abstract

The invention discloses a flexible tool dual driving mechanism for a surgical robot. The flexible tool dual driving mechanism for the surgical robot comprises a horizontal connecting plate. A first driving support is fixedly installed on the horizontal connecting plate. A motor is installed at one end of the horizontal connecting plate. A first driving wheel is fixedly connected to an output shaft of the motor. A second driving support is fixedly installed at the other end of the horizontal connecting plate. A first guide wheel, a second guide wheel, a middle transmission wheel and a second driving wheel are installed on the second driving support. A shell connecting base is fixed to the second driving support. An auxiliary driving wheel is connected to the shell connecting base. An auxiliary driving wheel shell is arranged on the shell connecting base in a covering mode. Two holes are symmetrically distributed in the auxiliary driving wheel shell in the vertical direction. Compression springs are installed in the two holes respectively. One ends of the two compression springs are pressed at the two ends of a rotary shaft of the auxiliary driving wheel respectively. The flexible tool dual driving mechanism for the surgical robot is convenient to operate and practical and can be conveniently applied to the robot for driving a flexible tool.

Description

technical field [0001] The invention relates to a driving mechanism for a minimally invasive surgical robot, in particular to a double driving mechanism of a flexible tool. Background technique [0002] The development of surgery has gone through traditional open surgery, endoscopic minimally invasive surgery, and then robot-assisted minimally invasive surgery. The surgical trauma to the patient is getting smaller and smaller. From the opening to the porous, and the non-porous surgery that enters the body through the natural orifice, the requirements for surgical tools are getting higher and higher, especially on the minimally invasive surgical robot through the natural orifice. Surgical tools that require surgical robots are becoming softer and will not harm the mouth, nose, anus, etc. At the same time, their operability is getting better and better, and the degree of automation and self-efficacy is getting higher and higher. In traditional natural orifice surgery and inte...
