Abstract

The invention discloses a remote motion center mechanism for a minimally invasive surgery, and belongs to the technical field of minimally invasive surgery equipment. A minimally invasive surgery robot in the prior art is large in size, complicated in structure, tedious in control and high in cost, is limited when popularized and used, and requires to be improved further. The remote motion center mechanism for the minimally invasive surgery comprises three branched bases, a moving platform, a surgical instrument mounting piece and three branch mechanisms, wherein the upper ends of the branch mechanisms are connected with the moving platform; the lower ends of the branch mechanisms are movably connected to a ring-shaped base through moving pairs; adjacent connecting rods of the branch mechanisms are connected by the moving pairs; at least one branch mechanism is connected with the ring-shaped base by a universal joint; and at least one branch mechanism is connected with the ring-shaped base through a spherical pair. By the structures of the spherical pair and the universal joint, the whole mechanism is small in size, compact in structure, simple to control and low in cost.

Description

Technical field [0001] The invention relates to a remote motion center mechanism for minimally invasive surgery, belonging to the technical field of minimally invasive surgery equipment. Background technique [0002] Compared with traditional open-bore surgery, minimally invasive surgery has the following advantages: small incision, light damage, safe and effective, can avoid exposure of organs to the air to reduce infection; can reduce the pain of patients after surgery, the patient can recover faster and can Resuming normal activities within a short period of time after surgery, the therapeutic effect is equal to or higher than that of traditional surgical methods; the postoperative wounds are more beautiful than traditional surgical procedures, and the scars after healing are smaller. With the continuous application and development of minimally invasive surgery in clinical surgery, minimally invasive surgical robots with higher surgical accuracy and ease of operation have also...
