Embodiment Construction

[0087] Below in conjunction with accompanying drawing, seven kinds of embodiments of the present invention are described in detail:

[0088] All embodiments of the present invention are in figure 1 The high-speed grinding surgery experimental platform shown is implemented. The experimental platform mainly consists of a linear three-axis platform (such as figure 2 shown), electric spindle 28, dynamometer I22, thermocouple 10 and control system 4. The linear three-axis stage includes X-axis structure, Y-axis structure and Z-axis structure. The X-axis structure is composed of an X-axis motor 5, an X-axis reducer 3, an X-axis screw 25, an X-axis guide rod 24 and an X-axis protection box 31. The X-axis screw 25 passes through the X-axis reducer 3 and the X-axis motor 5 Connection; there are 1 or 2 X-axis guide rods 24, and the X-axis guide rods 24 are arranged parallel to the X-axis lead screw 25. When the number of X-axis guide rods 24 is two, the two X-axis guide rods 24 are...

Abstract

The invention discloses an orthopedic surgery grinding experimental device with the cooling and electrostatic atomization film formation functions. The orthopedic surgery grinding experimental device comprises linear three-axis platform, an electric spindle and a workpiece fixing device. The linear three-axis platform can move front and back, left and right, and up and down. The linear three-axis platform comprises an X-axis structure capable of moving left and right, a Y-axis structure capable of moving front and back, and a Z-axis structure capable of moving up and down. The workpiece fixing device is fixed to the Y-axis structure. The electric spindle is fixed to the Z-axis structure and installed at the upper end of the workpiece fixing device. A grinding head is installed at the lower end of the electric spindle, a grinding cooling device is arranged in a grinding head handle or around the grinding head, and an electrostatic atomization film formation device is arranged around the grinding head. The high-speed grinding surgery experimental device can be suitable for drop irrigation type cooling, pouring type cooling, aerial fog type cooling, nano-fluid aerial fog type cooling and grinding region temperature drop modes for phase-change heat transfer type grinding heads, hydrophilic type grinding heads, electrostatic atomization inner-cooling grinding tools and the like.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a grinding experimental device for bone surgery with cooling and electrostatic atomization to form a film. Background technique [0002] Bone grinding is an essential procedure in neurological and orthopedic surgery, and high-speed micro-grinding wheels are commonly used clinically to remove bone pathology. However, high-speed grinding generates a lot of heat, leading to osteonecrosis and thermal damage to surrounding tissues, and also has a certain impact on the blood coagulation function of tissues. In clinical practice, physiological saline is often used as cooling fluid to reduce heat generation. Grinding heat damage has been recognized as a clinical concern because the temperature cannot be determined during the grinding process and thus the degree of thermal damage cannot be controlled. Kondo et al. pointed out that under the pouring saline cooling method, the maximum te...
