specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment. The wrist threading barrel of this embodiment is made of a base 1 and two connecting ears 2. The base 1 is provided with a first guide wheel fixing column 3, a second guide wheel fixing column 4, and a third guide wheel. The wheel fixed post 5 and the fourth guide wheel fixed post 6, the first guide wheel fixed post 3 and the third guide wheel fixed post 5 are distributed symmetrically with respect to the center of the wrist threading bucket base 1, the second guide wheel fixed post 4 and the third guide wheel fixed post 5 The four guide wheel fixing posts 6 are distributed symmetrically with respect to the center of the wrist threading bucket base 2, and the inner wall of the first guide wheel fixing post 3 is provided with two first guide wheels 31, and the two first guide wheels 31 are arranged along the first The height direction of the guide wheel fixed column 3 is aligned a...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 Illustrate, the height of the first guide wheel fixed column 3 of present embodiment is 5mm, the height of the second guide wheel fixed column 4 is 10mm, the height of the 3rd guide wheel fixed column 5 is 5mm, the 4th guide wheel fixed column 6 The height is 10mm. The diameter of the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, the fifth guide wheel and the sixth guide wheel is 2.4mm, the first guide wheel, the second guide wheel, the third guide wheel, The inner wheel grooves of the fourth guide wheel, the fifth guide wheel and the sixth guide wheel are distributed in the circumference of the base diameter of 3mm, through the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, the The guiding effect of the fifth guide wheel and the sixth guide wheel can make the driving wire acting on the rear end of the end threading barrel expand...

specific Embodiment approach 4

[0009] Embodiment 4: The outer diameter of the base 1 in this embodiment is 10 mm, so that the dual-arm robot can enter the body through an incision that meets the requirements of human skin for surgery, and the robot as a whole is easy to disassemble and carry. Other implementation manners are the same as the specific implementation manner 1.

Abstract

The invention provides a wrist threading barrel for a multi-degree-of-freedom flexible robot for single-incision laparoscopic minimally invasive surgery, relates to a robot for minimally invasive surgery, and aims at solving the problems of difficult structural design of tail end of the existing single-incision laparoscopic surgery robot, complex structure, large size and small integrity. The wrist threading barrel is that two first guide wheels are arranged on the inner wall of a first guide wheel fixing column and aligned in the height direction of the first guide wheel fixing column; a second guide wheel is arranged on the inner wall of a second guide wheel fixing column; two fifth guide wheels are arranged on the sidewall of the second guide fixing column; two third guide wheels are arranged on the inner wall of a third guide wheel fixing column; a fourth guide wheel is arranged on the inner wall of a fourth guide wheel fixing column; two sixth guide wheels are arranged on the sidewall of a fourth guide wheel fixing column and aligned in the height direction of the fourth guide wheel fixing column. The T wrist threading barrel is applied to single-incision laparoscopic minimally invasive surgery.

Description

technical field [0001] The invention relates to a wrist threading barrel for a multi-degree-of-freedom flexible robot for minimally invasive single-hole abdominal cavity surgery, and belongs to the technical field of surgical robots. Background technique [0002] At present, traditional surgical operations and the commonly used robotic system for minimally invasive abdominal surgery generally require large-area open incisions or 4-5 micro-incisions to perform operations. At present, in open surgery, there are generally disadvantages such as large trauma to the patient, high requirements for the doctor's operation, long postoperative recovery time, and high risk of cross-infection. At present, the equipment scale of the mainstream minimally invasive surgical robot system is relatively large, and interference and collision between the robotic arms and the equipment are prone to occur during the operation, and the operability and operability of the operation are reduced due to ...
