Wärmeentwicklung bei der Wasser-Abrasivstrahl-Osteotomie / Temperature Measurements During Abrasive Water Jet Osteotomy

Abstract

Working on bone is a major aspect of orthopaedic surgery. Despite its well-known appreciable thermal effects on the edges of the bone cut, the oscillating bone saw blade the oscillating saw remains the standard instrument both for cutting long bones and creating a bed for an endoprosthesis. The application of abrasive water jets offers the possibility of achieving an extremely precise curved cut in bone with no accompanying thermal effect. The thermographically measured absolute temperature increase at the cut edges seen with the water jet was 13 K maximum. The small process forces permit the application in automated handling systems.

Waterjet dissection of the vestibulocochlear nerve: an experimental study

“…Early use of waterjet dissection has been reported in liver and kidney surgery. 10,30,31,34,35,52 Subsequently, waterjet dissection was used in orthopedic procedures, 8,9,16,41,48 urological and hepatic surgery, 2,45,56 parotid surgery, 18,47 ophthalmological surgery, 6,18,19,[53][54][55] with endovascular techniques, 20 and in thoracoabdominal surgery. 15,17 The first application of waterjet dissection in neurosurgery was reported by Terzis et al 51 in 1989.…”

Water Jet Applicator for Interface Tissue Removal in Minimally Invasive Hip Refixation: Testing the Principle and Design of Prototype

“…Therefore, the feasibility of waterjet cutting of interface tissue as an alternative removal technique was explored [13]. Cutting with a waterjet does not generate heat and can be advantageous over conventional cutting tools such as mechanical cutters, laser dissectors, or ultrasonic aspirators [14]. Tissue can be cut within small spaces (i.e., the periprosthetic cavities) with very low reaction forces (<5 N) [15].…”

Pure Waterjet Drilling of Articular Bone: An in vitro Feasibility Study

“…For medical applications, differences in the material properties of human organs allow the precise dissection of soft tissue without damaging stronger tissues such as nerves or veins [4] to [6]. The absence of tissue heating [7] and the always sharp and clean cut, in particular, has led to the further exploration of waterjet technology for applications in orthopedic surgery [8] to [13]. Research in this has field primarily involved cutting cortical bone with abrasive (containing small solid particles) waterjets for preparation for arthroplasty [8] to [10] and [13] to [15].…”
