。In recent years, as various new materials have been adopted in orthopedics, plastic surgery, dentistry, and oral surgery, the frequency of grinding and drilling bone tissue and alveolar bone, and cutting teeth has increased. Conventionally, cutting was performed while pouring water or physiological table water, but when cutting bone, alveolar bone, or teeth, the rotational friction heat generated by the cutting tool destroys living tissue and causes inflammation. This may delay recovery and healing, resulting in poor tissue regeneration. It was invented for the purpose of causing tissue damage by frictional heat in order to improve healing.
本発明は、このような場合患者に、不快な感を少なくし
円滑迅速に切削を可能とした工具をもって外科手術並び

。In the surgical and dental treatment apparatus according to the present invention, the cutting tool is cooled by cooling gas obtained from liquefied gas or the like or cooled air, and while absorbing the heat generated during cutting, it is possible to rotate and drive the tool to achieve smooth and quick cutting. It was made so that it could be done.
以下、本発明を図示した実施例に基いて具体的纜説明す

に接続されている。As shown, the cutting tool 2 has a hollow cylindrical shape, and its tip (lower end in the figure) is open, and a cutting blade 3 is formed on the outer periphery of the tip. Cooling gas or cooling air is introduced into the cutting tool from the part supported by the grip part 1 (
A cooling gas supply path 4 is provided, and a liquefied gas such as liquefied carbon dioxide is introduced from a suitable liquefied gas supply source. Two conical baffle plates 5.6 are provided in the hollow part of the cutting tool 2, and the cooling gas guided from the cooling gas supply path 4 is passed between the baffle plates 5.60 and through the gap at the tip thereof as shown by the arrow. The cutting tool 2 is then put into the hollow part of the cutting tool 2 to cool it. An appropriate number of gas vent holes 7 are provided in the conical portion of the cutting tool 20. A support cylinder 8 is attached to the outer periphery of the grip portion 1 and the outer periphery of the cutting tool 2, and a surrounding member is provided on the outer periphery of the support cylinder 8 to surround the cutting tool 2 and is made of flexible rubber such as silicone rubber. The tip of the tip comes into contact with the plaster and gums, and when the tool 2 cuts bone tissue, teeth, etc., the cooling gas or air supplied to the hollow part of the tool 2 flows outside and into the oral cavity. The grip part 1 has an appropriate number of intake passages 1 for sucking liquefied gas.
0 is provided, and this intake channel 10 is connected to a suitable suction device.
従って、切削工具２内に冷却ガス供給路４から供給され

ツキンである。Therefore, the gas supplied into the cutting tool 2 from the cooling gas supply path 4 to cool the cutting tool 2 is prevented from leaking to the outside and into the oral cavity by the surrounding member 9, and is passed through the gas vent hole 7 and the intake path 10 to the outside. is exhausted. In addition, 11 in the figure is a packing.

である。The illustrated surgical and dental treatment apparatus has the above configuration, so when cutting bone tissue, alveolar bone, or teeth, the cutting tool 2 is rotated and the cutting blade 3 at the tip is used to cut the plaster to be cut. Also apply it to the teeth. On the other hand, by operating an appropriate cock (not shown) or the like, cooling gas is supplied through the cooling gas supply path 4 to cool the tool 2. In this case, the tool 2 is covered with a surrounding member 9, and the tip of the surrounding member 9 is in contact with the bone tissue, gums, etc., to prevent the cooling gas from flowing outside or into the oral cavity, and to close the air intake path 10. After that, the cooling gas is taken in and discharged to the outside. Note that the illustration shows a cutting tool that is cylindrical in shape and has a cutting edge formed around its tip, but the cutting tool is not limited to this, and the cutting tool may be hollow inside and cooled from the inside by receiving cooling gas therein. It goes without saying that other shapes and structures may be used as long as they are suitable. Furthermore, the surrounding member 9 is not limited to the shape shown in the drawings, but may of course be of any other shape as long as it is flexible and surrounds the cutting tool.

が良好になる利点がある。As specifically explained above, the surgical and dental treatment apparatus according to the present invention includes: a cutting tool that is hollow inside and has an open tip; a cooling gas supply path that supplies cooling gas into the hollow of the tool; It has an enclosing member that surrounds the cutting tool and a passage for exhausting air between the cutting tool and the enclosing member.By cooling the cutting tool with cooling gas, smooth and quick cutting can be achieved by rotating the tool. Moreover, the cooling gas from the intake passage is prevented from flowing outside and into the oral cavity. According to this, hard tissues such as bone tissue, alveolar bone, and teeth can be cut smoothly and quickly, so surgical operations and dental treatments can be performed quickly without causing discomfort to the patient. It has the advantage of improving tooth healing.
