Summary: In recent years, there has been an increase in the number of patients with orthopedic diseases, leading to a higher demand for orthopedic surgery. However, the occurrence of thermal necrosis and bone cracks during surgery has hindered the development of orthopedic procedures. This study designed a bionic drill based on the microstructure of the dung beetle's head and back, optimizing the microstructure configuration parameters. By establishing a mathematical model using infrared thermal imaging and acoustic emission signal technology, the cooling mechanism and crack suppression strategy were studied, resulting in improved cooling effects and crack suppression with the bionic drill.

Summary: Bone drilling is a crucial procedure in surgery, and its thermal characteristics directly affect bone damage and recovery. This study conducted an experimental investigation using advanced tools to analyze the thermal characteristics during cortical bone drilling in detail. The results show variations in maximum temperature at different locations, but no anisotropy in temperature distribution was observed. Processing parameters have a significant impact on thermal characteristics and may determine the extent of thermal damage.

Summary: The study reveals that damage induced by bone cutting extends beyond the necrotic region, with high cutting temperatures causing lower modulus, strength, and brittle behavior near the machined surface. In contrast, the bulk bone retains pristine properties and ductile behavior. This shows that drilling thermo-mechanical effects can impact bone both biologically and micromechanically, revealing previously neglected bone damage.

Summary: Mechanical and thermal damage during bone drilling can cause implant failure. High cutting force and temperature above 47 degrees C can lead to bone cell death and microcracks, affecting implant stability. A study comparing conventional bone drilling (CBD) and rotary ultrasonic bone drilling (RUBD) found that RUBD reduces cutting force, temperature rise, microcracks, and bone chip accumulation as compared to CBD.

Summary: This paper presents a comprehensive literature survey on the mechanical drilling of CFRP composites, covering drilling mechanisms, thermo-mechanical responses, drilling-induced damages, and the effects of process conditions. The study reveals that high cutting speeds and low feed rates improve the quality of CFRP holes. The optimization of process parameters, development of suitable tool geometries/materials, and application of proper cutting environments can effectively suppress drilling damage in CFRPs. Future research should focus on understanding the mapping mechanisms between tool geometries/materials, cutting environments, process parameters, and CFRP hole-making quality for optimized drilling strategies.

Summary: This study used a subject-specific musculoskeletal model and a high-accuracy intact finite element knee model to evaluate the kinematics and mechanics of an intact knee joint during the gait cycle. The results showed that internal rotation and parallel anterior translation are important movements for the normal function of the knee joint. Furthermore, the majority of the joint load is borne by the cartilage-cartilage contact, and there is significant contact pressure on the patellofemoral joint. These findings provide important theoretical foundations for the treatment of knee joint diseases and the design of knee prostheses.

Summary: In this study, a mode shape database-based TOMA (MSDB-TOMA) estimation method is proposed for the system dynamics of machine tools under variation caused by component movements. The study establishes a mode shape database to capture dynamics variation influenced by movements of cutting positions and demonstrates good fitting performance in a finite element model (FEM) of a machine tool. The proposed method shows precise estimation of system dynamics parameters, with a maximum error of within 0.04%, and indicates the feasibility of in-process dynamics recognition for real machining.

Summary: A novel elliptical vibration cutting (EVC) is introduced for bone cutting in this study to improve tissue removal and postoperative rehabilitation, increase efficiency and accuracy, and reduce operating force. The material removals of cortical bone and their cutting forces from EVC and conventional cutting (CC) were comprehensively recorded and analyzed using high-speed microscope imaging and the dynamometer, which showed significant improvements in chip morphology and average cutting force reduction in the EVC process. Additionally, it was discovered that the elliptical vibration of the cutting tool could promote fracture propagation along the shear direction. These findings have important theoretical and practical implications for the application of the innovative EVC process in osteotomy surgical procedures.
