A less invasive, flexible retractor-camera kit for video assisted endoscopic surgery
Opportunity
Mitral valve disease has had a significant global impact, affecting approximately 18.1 million people and causing 102,700 deaths in 2017. Over the past few decades, the incidence of mitral valve disease has seen a significant increase of 95 percent. Meanwhile, medical advancements have led to the rise of minimally invasive surgery, particularly the right mini-thoracotomy MIMVS, which has replaced traditional open heart mitral valve surgery as the preferred mode of surgery.
Despite the improvements in the MIMVS procedure, there is still room for further optimisation to enhance favourable outcomes. Presently, a total of four incisions are necessary to conduct the operation and properly visualise the operation using an endoscopic camera. But researchers are actively exploring alternatives to make the surgery even less invasive. In particular, a flexible retractor-camera kit for video-assisted endoscopic surgery.
Technology
This innovative approach seeks to eliminate the need for an additional incision, resulting in reduced patient trauma, reduced bleeding and lower risks of heart injury. The absence of a long and bulky tube attached to the patient will free up significant space in the surgical room and reduce manpower, as a nurse will no longer need to hold onto the apparatus during the procedure. The surgeon will have more space and fewer interruptions, as they no longer have to frequently reposition, defog or clean blood stains from the camera. After the procedure, it will also provide better cosmetics and faster healing for patients.
The retractor-camera kit includes two key features: an atrium lift retractor and a flexible video camera. The retractor acts as a small tool that gently holds open the atrium of the patient’s heart. A swivel ball joint allows it to move and rotate smoothly, giving the surgeon flexibility and control. The video camera can be attached to the retractor’s blade using magnets and can flexibly move around inside the patient’s body for optimal visualisation of the surgery.
The camera comes in different sizes to fit the heart sizes of respective patients. It also has a track or ball-joint feature for the camera to slip into the retractor blade and ‘click’ into place for stable imaging during the procedure. The angle of the miniature camera is adjustable even when attached to the blade, enabling the surgeon to point it at the exact targeted surgical site.
Compared to other traditional cameras and their attached accessories, the miniature camera is also more affordable.
