Abstract
Description
Technical Field
[0001] The invention relates to the technical field of medical instruments, in particular to a tool and a cooling device for medical bone deep hole drilling. Background Art
[0002] Usually when orthopedic surgeons perform surgery on patients, they often need to implant bone screws into the patient's bones. When implanting the bone screws, they need to drill holes in the patient's bones. Heat is generated during the drilling process. If the heat generated is too large, it will cause bone damage. Especially for deep holes, the heat generated is more difficult to dissipate. Therefore, the cutting part needs to be cooled during the bone drilling process. Therefore, the present invention proposes a tool and cooling device for medical bone deep hole drilling, which can spray low-temperature physiological saline through the through hole on the deep hole drilling tool, thereby reducing the heat generated at the cutting part. Summary of the invention
[0003] The present invention is to provide a tool and cooling device for medical bone deep hole drilling that can overcome the above-mentioned defects. The technical solution is as follows: A tool and cooling device for medical bone deep hole drilling, comprising a deep hole drilling tool and a spindle, wherein: the top of the deep hole drilling tool is clamped on the spindle, and is characterized in that: A sealing sleeve, two sealing rings, a sealing sleeve fixing device, a liquid delivery pump, a liquid storage tank and two connecting pipes are additionally provided, wherein: the outer rings of the two sealing rings are respectively installed in the two internal grooves of the sealing sleeve, the side of the deep hole drilling tool is installed on the inner rings of the two sealing rings, the connecting hole on the side of the sealing sleeve is connected to one end of the liquid delivery pump through the connecting pipe, the other end of the liquid delivery pump is connected to the connecting hole on the liquid storage tank, and the top of the sealing sleeve is fixedly connected to the bottom of the main shaft through the sealing sleeve fixing device.
[0004] The tool and cooling device for medical bone deep hole drilling are characterized in that the bottom of the deep hole drilling tool is composed of 4 straight cutting edges and 4 cutting planes, the diameter of the part of the deep hole drilling tool close to the top is smaller than the overall diameter of the deep hole drilling tool, there is an annular groove below the part with a smaller diameter of the deep hole drilling tool, and there is a through hole on each of the 4 cutting planes, and the through hole passes through the annular groove and the cutting plane.
[0005] Its working principle is: the liquid storage tank is filled with low-temperature saline, and the liquid delivery pump delivers the low-temperature saline in the liquid storage tank to the sealing sleeve through the connecting pipe. Since the diameter of the top part of the tool is smaller than the overall diameter of the deep hole drilling tool, this part of the tool will form a continuous cavity with the connecting hole and the annular groove on the side of the sealing sleeve to facilitate the flow of liquid. Finally, the low-temperature saline is sprayed onto the cutting part through the through hole on the tool.
[0006] Compared with the prior art, the present invention has the advantages that by using the deep hole drilling tool and the cooling device with the characteristics to perform bone drilling, the heat generated during the bone drilling process can be significantly reduced, thereby avoiding bone damage.
