Bone grinding device

Abstract

A bone grinding device comprises a machine rack, a three-dimensional linear lead screw sliding table, an electric main shaft, a spherical grinding head, a thermoelement and precise flat tongs, wherein the three-dimensional linear lead screw sliding table, the electric main shaft, the spherical grinding head, the thermoelement and the precise flat tongs are installed on the machine rack, and the precise flat tongs are used for clamping a bone grinding sample. The left end of the electric main shaft is connected with an electric main shaft driving motor which is installed on a vertical sliding table body of the three-dimensional linear lead screw sliding table, the spherical grinding head is installed at the right end of the electric main shaft through a clamp, and a thermoelement probe is placed in a groove in the bottom of the bone grinding sample. The bone grinding device further comprises a low-temperature spray cooling device, the low-temperature spray cooling device comprises a gas source processing element, a liquid container, a cooling chamber, a gas-liquid mixer and a nozzle, wherein the liquid container is used for containing low-temperature normal saline, the gas source processing element comprises a gas pump, a filter, a pressure regulator and a drier, and the left end of the nozzle is fixed to a shell of the electric main shaft driving motor. By means of the bone grinding device, efficient cooling in the bone grinding process can be achieved, and it is ensured that a bone surgery operation is performed smoothly.

Description

Technical field [0001] The invention belongs to the technical field of precision grinding and processing, and particularly relates to a bone grinding device. Background technique [0002] In recent years, various bone tissue diseases (such as bone hyperplasia, osteoarthritis, bone atrophy or necrosis, bone cancer and fractures, etc.) have been increasing. Plastic surgery, dental implant technology, and minimally invasive surgery have emerged and flourished. In the process of orthopedic surgery, some traditional machining methods such as drilling, sawing, milling and other cutting methods have been widely used. Different from traditional mechanical processing, the key elements that need to be paid attention to in the bone tissue processing process are: 1. Maintain the high efficiency of material removal to shorten the operation time and reduce the operation risk; 2. Minimize the various damages to normal human tissues caused by the grinding process , Including structural crack da...
