This paper describes a mechatronic (mechanical and electronic) realization of the optimal trajectory planning and guidance algorithms for minimally invasive surgical training. Specifically, the realization implements optimal navigation paths for surgical instruments in laparoscopic exercises. The underlying system platform is the Computer-Aided Surgical Trainer (CAST) that consist of mechanical...

BACKGROUND The evidence base supporting minimally invasive sacroiliac (SI) joint fusion (SIJF) surgery is increasing. The work relative value units (RVUs) associated with minimally invasive SIJF are seemingly low. To date, only one published study describes the relative work intensity associated with minimally invasive SIJF. No study has compared work intensity vs other commonly performed spine...

Preprosthetic surgeries are generally dealt with surgical procedures performed to facilitate fabrication of prosthesis or improve the prognosis of prosthodontic care. In general the surgical procedures include various soft and hard tissue procedures which are restricted intraorally. Maxillofacial prosthodontics is not restricted to restorations performed intra-orally. Various extraoral surgical...

The surgical management of pediatric upper urinary tract calculi has evolved from open surgery to minimally invasive techniques. With advancement in instrumentation, endourological procedures are being performed more commonly in children. However, the endourological management of renal and ureteral stones in the pediatric population is considered challenging, owing to the smaller size of the ur...

OBJECTIVE As the use of minimally invasive surgery in cardiothoracic surgery increases, so does the need for simulation and training. We developed a heart model for simulation and training of minimally invasive cardiac surgery, particularly minimally invasive mitral valve repair using our new three-dimensional printing system. METHODS Digital imaging and communication in medicine data from pa...

Advances in surgery for atrial fibrillation from cut and sew technique to thoracoscopy and new energy source have enabled minimally invasive approach which avoids median sternotomy and cardiopulmonary bypass. However, minimally invasive approach is unable to match the outcome of classic surgical technique due to difficulty in creating some of linear ablation lines. Hybrid procedure using cathet...

Breast cancer management has been evolving toward minimally invasive approaches. Image-guided percutaneous biopsy techniques provide accurate histologic diagnosis without the need for surgical biopsy. Breast conservation therapy has become the treatment standard for early-stage breast cancer. Sentinel lymph node biopsy is a new procedure that can predict axillary lymph node status without the n...

INTRODUCTION Definitive treatment of localised colorectal cancer involves surgical resection of the primary tumour. Short-stay colectomies (eg, 23-hours) would have important implications for optimising the efficiency of inpatient care with reduced resource utilisation while improving the overall recovery experience with earlier return to normalcy. It could permit surgical treatment of colorect...
