IEEE Transactions on Biomedical Engineering, 2006
This paper presents a feasibility study of drilling in fresh wet bone tissue in vitro using the microwave drill method [Jerby et al, 2002], toward testing its applicability in orthopaedic surgery. The microwave drill uses a near-field focused energy (typically, power under approximately 200 W at 2.45-GHz frequency) in order to penetrate bone in a ...

Drill wear monitoring in cortical bone drilling
Medical Engineering & Physics, 2015Medical drills are subject to intensive wear due to mechanical factors which occur during the bone drilling process, and potential thermal and chemical factors related to the sterilisation process. Intensive wear increases friction between the drill and the surrounding bone tissue, resulting in higher drilling temperatures and cutting forces. Therefore,

Cortical bone drilling and thermal osteonecrosis [PDF]
Clinical Biomechanics, 2012 Bone drilling is a common step in operative fracture treatment and reconstructive surgery. During drilling elevated bone temperature is generated. Temperatures above 47°C cause thermal osteonecrosis which contributes to screw loosening and subsequently implant failures and refractures.The current literature on bone drilling and thermal osteonecrosis is

Surgical Bone Drilling: A Review
Volume 3: Biomedical and Biotechnology Engineering, 2019Abstract Bone drilling is an important step in orthopedic surgeries for the reconstruction and repair of fractured bones. The main concern in bone drilling is to create holes without causing minimum damage to the bone tissues. It is well reported that high temperature and high force in drilling cause bone thermal necrosis leading to the ...

In this chapter, we describe a reproducible, simple to use method that allows correct femoral tunnel placement without the need for aggressive notch debridement. This outside-in technique has a number of advantages over the more conventional in-out femoral tunnel placement via the anteromedial portal.

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

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.

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 ...

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.

In case of fracture or crack of human bones, the most important is to return the bone parts as precisely as possible into their previous positions. The operative or surgery method in that case is the best. During the surgery traumatologist drill the bone in order to set the immobilization screws and plates and the goal is to insure maximum avoidance of
