Single Position Surgery

Single-position surgery is an operative approach in which a patient remains in one carefully planned position while surgeons complete multiple steps of a procedure, reducing the need for intraoperative repositioning. The technique relies on preoperative imaging, precise patient alignment, appropriate anesthesia and monitoring, and surgical access designed to reach the required anatomy from a single orientation. In medicine, it can support minimally invasive spine and orthopedic procedures that traditionally involve changing positions between stages. By streamlining positioning and maintaining consistent access, single-position surgery may shorten operating-room workflow, reduce handling-related risks, and improve coordination among surgical teams, although its suitability depends on patient anatomy, procedure complexity, and available equipment.

Single-Port Robotic-assisted Transaxillary Breast-conserving Surgery: A Prospective, Single-arm, Non-randomized Phase IIa Clinical Trial

0 Views •

2025

This prospective study evaluated the implementation of a novel, single-port, robotic platform in oncoplastic breast-conserving surgery for malignant lesions. The primary endpoint focused on technical success, defined as the achievement of tumor-free resection margins confirmed by intraoperative frozen-section histopathology, with secondary assessment of aesthetic outcomes and life quality score of patients.

Single-port Non-liposuction Endoscopic Axillary Lymph Node Dissection in Breast Cancer Surgery

2026

This study describes a standardized surgical procedure for single-port endoscopic axillary lymph node dissection without liposuction in breast cancer. Indicated for patients with biopsy-confirmed nodal metastasis or positive sentinel lymph nodes, the technique emphasizes preservation of critical structures, particularly the intercostobrachial nerve, to reduce postoperative morbidity and optimize functional recovery.

Robotized Testing of Camera Positions to Determine Ideal Configuration for Stereo 3D Visualization of Open-Heart Surgery

0 Views •

2021

The human depth perception of 3D stereo videos depends on the camera separation, point of convergence, distance to, and familiarity of the object. This paper presents a robotized method for rapid and reliable test data collection during live open-heart surgery to determine the ideal camera configuration.

Generating Single Positive CD8 T Cells from Induced Pluripotent Stem Cells

This video demonstrates an assay to generate tumor antigen-specific induced pluripotent stem cell (iPSC)-derived CD8αβ+ T Cells. Tumor antigen-specific iPSCs are grown on a stromal cell monolayer and differentiated into hematopoietic progenitor cells (HPCs). The HPCs are differentiated into CD4+ CD8+ double-positive T cells using a differentiation medium. These cells are then stimulated to generate single-positive T cells expressing CD8.
