AI Technical Summary

Technical Problem

In single-port remote surgical systems, maintaining the inflatable gas pressure and introducing auxiliary instruments presents challenges when the constrained remote center of motion is located proximal to the patient's body opening, especially in the case of multiple instrument clusters where instrument access is obstructed.

Method used

An instrument access device is designed, including a cover and a coupling component. The cover provides a sealed space to maintain the pressure of the injected gas and receives multiple surgical instruments through the proximal coupling component. The rotation of the auxiliary instruments is achieved by using a gear train or linkage mechanism without twisting the cover, ensuring flexible operation of the instrument cluster.

Benefits of technology

It enables the maintenance of injection gas pressure in a single-port remote surgical system, while allowing for the flexible introduction and operation of auxiliary instruments, reducing the obstruction of auxiliary instruments by instrument clusters, and improving the flexibility and efficiency of surgical procedures.

Abstract

Instrument access guide. Medical devices for surgical procedures are disclosed, particularly procedures involving manipulation of a surgical instrument end effector proximate a skin surface at an incision site. According to some embodiments, an instrument access device is configured to couple to a wound retractor at a distal end of the device and receive a multi-instrument access guide in a port at a proximal end of the instrument access device, with an envelope between a distal end and a proximal end defining a sealed cavity for maintaining a gas pressure. Various embodiments provide means for rotating an auxiliary port in the envelope around a port receiving an instrument access guide without twisting the envelope. Various envelope shapes are also disclosed. An instrument access guide that aligns a surgical instrument shaft is also disclosed.
