Abstract

The invention provides a bone vibration drilling platform with a parameter measurement function, comprising two parts, namely, a bone vibration drilling platform and a parameter measurement system. The bone vibration drilling platform comprises a vibration platform used for fixing a bone sample and providing controllable vibration, and a drilling platform used for controlling the height of a drill bit and a feeding speed. The parameter measurement system comprises a laser micro-distance sensor used for measuring the amplitude and the frequency of the vibration platform, a pressure sensor used for measuring a feeding force, and a small thermocouple temperature measurement unit for measuring temperatures at the drilled parts of the bone sample. The bone vibration drilling platform with a parameter measurement function provided by the invention can be used for realizing bone vibration drilling, and performing real-time online measurement on four parameters, namely, cutting heat, the feeding force, the vibration frequency and the amplitude during a drilling process, thus providing a hardware platform for searches on control means for the cutting heat during the bone drilling process. The method and the equipment used for the bone vibration drilling platform with a parameter measurement function provided by the invention are simple, low in cost and great in robustness.

Description

technical field [0001] The invention relates to various fields such as orthopedics, medical treatment, machinery, etc., and more specifically relates to a bone vibration drilling platform with a parameter measurement function. Background technique [0002] With the continuous promotion and deepening of the minimally invasive concept in orthopedic surgery, it has become an important direction for the future development of orthopedic surgery to minimize the damage to patients caused by surgical operations on the premise of ensuring the surgical effect. Bone drilling is one of the most basic and common surgical operations in orthopedic surgery. The cutting heat generated during the drilling process will cause irreversible damage to the bone. Thermal injury can lead to bone gangrene and even osteomyelitis, which will not only affect postoperative recovery but also directly affect the effect of surgery. [0003] Vibration drilling is a new drilling method that adds axial high-fr...
