In minimally invasive heart surgery, surgeons make small incisions in the side of your chest, between your ribs, to reach your heart. Surgeons conduct the procedure using long instruments. Minimally invasive heart surgery involves making small incisions in the right side of your chest to reach the heart between the ribs, rather than cutting through the breastbone, as is done in open-heart surgery. Minimally invasive heart surgery can be performed to treat a variety of heart conditions. Compared with open-heart surgery, this type of surgery might mean less pain and a quicker recovery for many people. Many types of heart procedures may be conducted with minimally invasive heart surgery, including:.
Reducing access trauma has been a focal point for modern surgery and tackling the challenges that arise from new operating techniques and instruments is an exciting and open area of research. Lack of awareness and control from indirect manipulation and visualization has created a need to augment the surgeon's understanding and perception of how their instruments interact with the patient's anatomy but current methods of achieving this are inaccurate and difficult to integrate into the surgical workflow. Visual methods have the potential to recover the position and orientation of the instruments directly in the reference frame of the observing camera without the need to introduce additional hardware to the operating room and perform complex calibration steps. This thesis explores how this problem can be solved with the fusion of coarse region and fine scale point features to enable the recovery of both the rigid and articulated degrees of freedom of laparoscopic and robotic instruments using only images provided by the surgical camera.
Purpose: This study describes an incision-free minimally invasive conjunctival surgical MICS technique to repair late-onset leaking blebs after trabeculectomy. Methods: A surgical technique to repair leaking blebs without incision or excision of conjunctiva is described. This is followed by retrospective review of all patients treated at the Glaucoma Unit at St.
