Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a surgical operating arm and a method thereof for facilitating switching of tools. Background Art

[0002] In surgical operations, doctors can use equipment such as robotic surgical systems or robotic arms to perform precise movements, reduce human errors, and provide stable support during operations, especially long operations.

[0003] Chinese patent CN217286109U discloses a drag arm for clamping surgical instruments, including a bedside mounting assembly connected to an operating bed, a lifting and adjusting assembly connected to the bedside mounting assembly, a plane adjustment assembly connected to the lifting and adjusting assembly, and a clamping mechanism arranged at the end of the plane adjustment assembly. The drag arm can conveniently move the required surgical instruments to the required positions through the cooperation of the various components. However, the drag arm still has the following problems: 1. The operable space of the dragging arm is the activity space formed by the inner lifting tube, the first rotating arm and the second rotating arm. The operable range is small during surgery, and the dragging arm is fixed by a bedside mounting assembly. It is inconvenient to change its position during surgery, which makes it difficult to meet the large-scale operation requirements of surgery. 2. The drag arm only fixes a group of surgical instruments through a clamping mechanism. However, in actual surgery, it is often necessary to maintain the support effect of lamps, endoscopes and related surgical instruments for a long time, the position of each surgical instrument also needs to be adjusted separately, and the surgical instruments need to be switched frequently.

[0004] Based on this, the present invention designs a surgical operating arm and method for convenient tool switching to solve the above-mentioned problems. Summary of the invention
