Abstract

Background

This preclinical study evaluated the safety and technical feasibility of robot-assisted partial gastrectomy (RPG) using the Carina Platform in a porcine model to accumulate evidence for clinical translation.

Methods

Six pigs underwent RPG (4 with Plan A, 2 with Plan B setups). The acute group (n = 3) were euthanised 1-h postoperation, while the chronic group (n = 3) survived 28 days for recovery assessment. Operative parameters (time, blood loss), complications, and ergonomics (NASA-TLX) were recorded. Necropsy evaluated surgical site healing.

Results

All procedures were successfully completed. Mean operative time was 109 ± 34 min. One intraoperative liver injury was controlled without complications. The chronic group showed no infections, with necropsy confirming recovery. Surgeons reported favourable ergonomic scores.

Conclusion

RPG using the Carina Platform is safe and technically feasible in porcine models, supporting future clinical trials.

猪胃部分切除机器人手术系统的可行性研究
本临床前研究评估了机器人辅助胃部分切除术(RPG)在猪模型上使用Carina平台的安全性和技术可行性,为临床转化积累证据。方法对6头猪进行RPG治疗(A方案4头,B方案2头)。急性组(n = 3)术后1 h实施安乐死,慢性组(n = 3)术后28 d进行康复评估。记录手术参数(时间、出血量)、并发症和人体工程学(NASA-TLX)。尸检评估手术部位愈合情况。结果所有手术均顺利完成。平均手术时间109±34 min。术中1例肝损伤得到控制,无并发症。慢性组无感染,尸检证实康复。外科医生报告了良好的人体工程学评分。结论基于Carina平台的RPG在猪模型上是安全且技术可行的,为未来的临床试验提供了支持。

期刊介绍: The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
