Novel Retractor-Camera System Facilitates Less Traumatic Minimally Invasive Procedures and Declutters the Operation Field.
Objective: To develop a novel endoscopic system that reduces trauma to the patient and declutters the surgical field for the surgeon in minimally invasive heart valve surgery.
Methods: We designed and developed a retractor-camera combination for minimally invasive heart surgery; the cable and camera were connected to the underbelly of the left atrial retractor blade to provide an illuminated, wide-angle view of the mitral valve. We conducted ex vivo, in vivo, and, ultimately, a first-in-man randomized, nonanonymized clinical trial on 20 patients who required minimally invasive mitral valve surgery. Data from the preoperative period and the immediate postoperative period were gathered, and patients were followed for 3 months.
Results: Our camera-retractor combo demonstrated safe and efficient exposure and vision in all detailed studies. The total operation time for the intervention group (316.5 ± 65.1 min) was slightly shorter than for the control group (317.5 ± 50.8 min). There was no significant difference in the ability to provide exposure of the mitral valve and surrounding left atrial tissue for both control and test articles. The novel camera-retractor reduced clutter in the operation field substantially and eliminated chest penetration for the camera. We also observed that the camera did not fog, did not stain with blood, and did not require frequent corrections to its position.
Conclusions: We launch a novel atrial retraction-imaging platform that is less invasive for the patient and eliminates clutter and redundant movements for the surgeon.
期刊介绍:
Innovations: Technology and Techniques in Cardiothoracic and Vascular Surgery is the first journal whose main mission is to disseminate information specifically about advances in technology and techniques that lead to less invasive treatment of cardiothoracic and vascular disease. It delivers cutting edge original research, reviews, essays, case reports, and editorials from the pioneers and experts in the field of minimally invasive cardiothoracic and vascular disease, including biomedical engineers. Also included are papers presented at the annual ISMICS meeting. Official Journal of the International Society for Minimally Invasive Cardiothoracic Surgery
