Evaluation of delamination in drilling of bone
Medical Engineering & Physics, 2015In this paper, delamination of bone associated with drilling is investigated using design of experiments. Experiments have been planned based on L25 design of the orthogonal arrays with different conditions of drill bit, spindle speed and feed rate.

An objective assessment for bone drilling: A pilot study on vertical drilling
Journal of Orthopaedic Research, 2022AbstractThe purpose of this study is to propose a quantitative assessment scheme to help with surgical bone drilling training. This pilot study gathered and compared motion and force data from expert surgeons (n = 3) and novice residents (n = 6). The experiment used three‐dimensional printed bone simulants of young bone (YB) and osteoporotic bone (OB),

The drill biopsy of bone lesions
Clinical Radiology, 1972The nature of a bone lesion can only be confirmed by histological examination, but an open biopsy may be difficult especially when inaccessible sites are involved. An accurate and early report can, however, be obtained by drill biopsy. In a series of 100 biopsies of lesions clinically considered malignant, the diagnosis was confirmed in 93 cases and ...

Fingernail Drill in Bone Surgery
The Journal of Dermatologic Surgery and Oncology, 1987Abstract. The fingernail drill is useful in bone surgery. It is useful in aiding the excision of bone and in the stimulation of granulation tissue in exposed cranial bone. The drill is safe, efficient, and easy to operate.

Optimization of Drill Bits for Bone Drilling Procedure
Volume 1: Additive Manufacturing; Bio and Sustainable Manufacturing, 2018The paper presents a methodology to optimize drill bits to realize safe drilling of bone materials for many surgeries like orthopedics and neurosurgery. First, a mechanistic model is introduced to relate drilling forces to main drill bit geometry parameters. Then a genetic algorithm is developed to optimize drill bit geometry parameters by minimization

Drilling Force and Temperature of Bone by Surgical Drill
Advanced Materials Research, 2010Drilling force and temperature of tibia at the high speed drilling for improving the design of surgical drills are very important. In this paper we describe experiments using pig tibia bones, measuring the drilling force and temperature of a new design of drill bit and compare the results against a twist drill.

Effect of drill speed on bone temperature
International Journal of Oral and Maxillofacial Surgery, 1996Measurements of bone temperature rise were recorded during drilling of bovine cortical bone specimens. A surgical drill (Stryker-100) was fitted with a custom-designed speedometer for monitoring the rotational speed during the drilling, and the drill was mounted on a specially constructed drill press.

Thermological Study of Drilling Bone Tissue with a High-speed Drill
Neurosurgery, 2000To perform a detailed quantitative analysis of the effect of intermittent drilling and irrigation to lower the temperature during high-speed drilling.We examined the thermal changes for 15 bone flaps while drilling a 7- x 7-mm area for 18 seconds and a specific point for 9 seconds, under the following conditions: continuous or intermittent drilling ...

The effect of bone drilling on pain in gonarthrosis
International Orthopaedics, 1995Seventy-seven patients with mild to moderate gonarthrosis of the knee were treated by subchondral bone drilling, and followed for from 2 to 7 years. Patients with generalised arthrosis benefited more than those with unicompartmental involvement. Pain, assessed by a visual analogue scale, was significantly reduced compared with a control group of 16 ...

Bone recognition during the drilling process
2016 6th IEEE International Conference on Biomedical Robotics and Biomechatronics (BioRob), 2016When using automatic bone drilling tools, surgeons lose tactile information regarding bone condition and health. The aim of this work is to extend the capabilities of such automatic bone drilling systems by trying to identify cortical bone tissue properties through the analysis of the thrust force. Multiple experiments are performed in a CNC machine to
