In the context of an aging population, the concept of peaceful end-of-life care has gained increasing significance as an essential component of individuals\' fundamental well-being. This underscores the importance of researching and developing hospice care facilities and service systems dedicated to providing a tranquil resting environment. This study focuses on selected hospice care buildings, examining their service model evolution and architectural design. Through case analyses, it explores contemporary hospice care architecture, identifying various types and spatial design features that cater to the end-of-life needs of individuals. The findings guide the design of hospice care buildings in China, emphasizing patient-living areas, medical care zones, and auxiliary functional spaces. This comprehensive approach aims to enhance terminally ill patients\' comfort, serenity, and dignity. Moreover, it aims to provide emotional and post-funeral support to terminally ill patients\' families.

OBJECTIVE: Explore an accurate transosseous tunnel drilling method based on three-dimensional (3D) printing technology for acromioclavicular joint reconstruction (ACD), design a guide design, and evaluate its accuracy.
METHODS: Using Mimics software to reconstruct 100 cases of acromioclavicular joint computed tomography (CT) data. In design 2, the non-collinear tunnel is superimposed on the 3D model, and a virtual drilling is performed between the clavicle and the coracoid using a triple inner gusset. Then, in the Geomagic Studio software model, an elliptical plane is calculated and extracted as a guide design for precise drilling. Then put the design and the 3D shoulder model together for 3D printing. Ten lengths were measured, and the effects of the virtual model, the actual model, and the guide rail design were compared.
RESULTS: We successfully compared 10 parameters of 3D virtual model and actual model. There was no significant difference between actual and virtual bone tunnels in 10 measurements (P > 0.05).
CONCLUSIONS: The accuracy of ACD combined with 3D printing guidance design technology in the transosseous tunnel of adult shoulder is reliable.
