A new thermal model for bone drilling with applications to orthopaedic surgery.

This paper presents a new thermal model for bone drilling with applications to orthopaedic surgery. The new model combines a unique heat-balance equation for the system of the drill bit and the chip stream, an ordinary heat diffusion equation for the bone, and heat generation at the drill tip, arising from the cutting process and friction. Modeling of the drill bit-chip stream system assumes an...

An experimental investigation on thermal exposure during bone drilling.

This study presents an experimental investigation of the effects of spindle speed, feed rate, and depth of drilling on the temperature distribution during drilling of the cortical section of the bovine femur. In an effort to reduce measurement uncertainties, a new approach for temperature measurements during bone drilling is presented in this study. The new approach is based on a setup for prec...

Temperature effects in the drilling of human and bovine bone

Bone is an anistropic material, the drilling of which is an essential part of internal ®xation in orthopaedic and trauma surgery. Some research has been carried out into the drilling of bone, but there are no de®nitive recommendations available on the most suitable drill shape or on the optimum drilling speed that should be used in surgical practice. The heat generated during the drilling of bo...

An Experimental Research on Bone Drilling Temperature in Orthopaedic Surgery

The bone drilling temperature fields under different cutting parameters and cooling modes were experimental researched by using common twist drill, diamond punching pin, diamond bullet-like grinding head and diamond spherical grinding head. Three cooling modes were applied, namely, natural air cooling, normal saline pouring cooling and normal saline spray cooling. K-thermocouple was used to mea...
