Harris SJ, Mei Q, Arambula-Cosio F, et al., 1996, Robotic aided transurethral resection of the prostate, ISSN: 0963-3308
Transurethral resection of the prostate is a very delicate procedure that is repetitive and requires the removal of many small chips of tissue. There have been proposals to use robots for this procedure to relieve surgeons of some of the burden. A robot was designed for prostatectomy which could work within a small volume, approximately the size of a large prostate. The robot was tested both in a laboratory and in a surgical environment. The tests indicate an accuracy to within 1.5 mm of the cavity specified by the surgeon, and had a repeatability of approximately 1 mm. These figures were considered suitably accurate for use with human subjects and comparable with those achieved by human surgeons.

Nathan MS, Wickham JEA, Davies B, 1995, Robotic transurethral electrovapourization of the prostate, Minimally Invasive Therapy and Allied Technologies, Vol: 4, Pages: 283-287, ISSN: 1364-5706
The need for an alternative management to transurethral resection of the prostate (TURP) is indicated because of its known post-operative morbidity and the increasing incidence of benign prostatic hyperplasia requiring operation with a considerably costlier effect on health care budgets. Despite the search, no beneficial alternative has yet emerged and it is envisaged that robotizing the procedure may be of benefit. The design of a purpose-built robot is described which consists of a specially designed motorized safety frame, a dedicated motion controller, an integrated ultrasound and camera system and a computer system. The software and the procedural protocol are briefly described. Clinical trial is in progress with a rapid set-up time of only 8min. It is concluded that the robot is ultimately expected to be an ideal alternative to conventional TURP. © 1995 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
Davies B, 1995, Tactile sensing for telesurgery, ISSN: 0963-3308
The issues involved in the use of tactile sensing systems for telesurgery are examined. Several problems arises from this application including the difficulty in conveying tactile or force information feedback as well as the use of force to control the master/slave system. Tests have been carried out at the Imperial College on a prototype master/slave system to cut soft tissue. Data suggest that it is possible to recognize the moment of tissue penetration by a dip in force levels and then retract the slave automatically using local feedback to control the depth of cut.
Davies B, 1995, Robotics in minimally invasive surgery, ISSN: 0963-3308
The role of robotics in minimally invasive surgery is discussed. Surgery robots are not only externally powered reprogrammble manipulating devices but also computer assisted devices. They may also include sensors attached to tools to keep track of the tool relative to the target. The importance of these micro sensors in transmitting data back to the surgeon is emphasized. A number of special purpose surgery robots are enumerated and their specific functions are discussed.

Potamianos P, Davies BL, Hibberd RD, 1994, A Robotic System for Minimal Access Surgery, Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, Vol: 208, Pages: 119-126, ISSN: 0954-4119
A computerized manipulator-assisted method is presented to facilitate the execution of minimal access surgical procedures. The proposed method employs a passive manipulator to assist the surgeon in the three-dimensional spatial location of anatomical features, using general purpose X-ray fluoroscopy or ultrasound imaging equipment with video input/output facilities. The method enables the three-dimensional navigation of surgical tools in correlation with two-dimensional medical images. A system is under development at Imperial College, London, for the application of this method to minimally invasive renal procedures. The system will enable the spatial location of renal calculi and the establishment of percutaneous renal track central axes. The proposed method is compatible with existing urological procedures and imaging equipment and enables the correlation of X-ray and ultrasound imaging modalities. © 1994, Institution of Mechanical Engineers.

Razban A, Sezgin OS, Davies BL, 1991, Real time control of automated adhesive dispensing, Pages: 145-150
In order to ensure the process integrity for reliable structural adhesive joints, and due to the change of adhesive viscosity with environmental variation, strict control for the dispensing process is needed. This paper presents a real time control method for dispensing adhesive by using a vision sensor as a feedback controller. The system comprises a six axes robot which carries a digital controlled dispensing gun, a camera and a laser line of light to monitor the bead parameters. The bead parameters can be optimised through on line process control to ensure that the bead stays in the desired bandwidth. The control process is done by continuous communication between the robot controller, dispensing controller and microcomputer which hosts vision and control algorithms. The implementation and software issues are addressed. The software performance and results are also discussed.
