Conventionally, in osteotomies in neurosurgery and plastic surgery, Kerrison forceps, alveolar bone forceps, drills, scalpels, gouges (circle only), etc. are used to cut and separate biological tissue, especially bone tissue, cartilage tissue, and periosteum. However, the cutting and separation work is inefficient and takes a long time, requires a great deal of labor on the part of the operator, and requires advanced techniques for cutting and separation.

あつた。 In addition, many surgical tools have been developed that utilize ultrasonic waves. Surgical tools (for example, , special public service 1977
89197) and a surgical tool having a medullary cavity rasp connected to an ultrasonic vibration source, which was developed for cutting and separating hard and soft biological tissues. However, surgical tools that use ultrasonic vibrations to crush and remove biological tissues by suction are difficult to use for cutting biological tissues, especially hard tissues such as bones, or separating periosteum. Surgical tools that have a bone marrow rasp connected to a source can cut cartilage and bone, but the biological tissue on the cut surface is destroyed by the frictional heat of the rasp, making it difficult to use for separating and cutting periosteum, etc. This is difficult, and during continuous operation, surgical tools generate heat due to ultrasonic vibrations.
The disadvantage was that the mechanical strength of the surgical tool itself was also reduced.

都合である。 In Fig. 1, the horn 1 and the spherical body 3 are made by integral processing, but as shown in Fig. 2, the spherical body 3 is provided with a connecting part 5, and can be connected and replaced with the horn 1 by an appropriate method such as a screw. It is also possible to do this. Also,
In FIG. 3, a vibration transmitting part 6 is provided between the spherical body 3 and the connecting part 5, and the spherical body 3 can be replaced by connecting the horn 1 and the connecting part 5 by a suitable method such as a screw. The dimensions of the spherical body 3 vary depending on the purpose of use and the treatment area, but the diameter is 1~
The range may be about 10 mm, and if the structure is replaceable as in the examples shown in FIGS. 2 and 3, it is convenient because it can be replaced during the treatment depending on the situation.
第４図は本考案の他の実施例となる医療用超音

削をスムーズに行うことが出来る。 Drills, gouges, rasps, etc., which have been conventionally used to cut and separate hard bone tissue, etc., have the disadvantage that the cut surface of the cut hard bone tissue, etc. is not uniform, and the wound healing period is long. In contrast, in the present invention, the tip of the horn is made into a spherical shape, the surface of which is knurled and subjected to ultrasonic vibration, making it possible to finish the stump surface uniformly and smoothly. In addition, an ultrasonic horn with only one tip is useful for cutting hard bone tissue, but is not suitable for shaving work, that is, surface cutting, whereas the ultrasonic horn of the present invention Because it uses a spherical surface, surface cutting can be performed particularly smoothly.

According to the present invention, the cutting and separation of biological tissue, especially bone tissue and cartilage tissue, does not require technical skill and the treatment time can be shortened.In addition, precise cutting can be performed and the stump of the treated area can be cut and separated. Since the surface can be finished uniformly and smoothly, the wound healing period can be significantly shortened compared to conventional methods. In addition, by increasing the cooling effect of the ultrasonic horn, it is possible to prevent deterioration of the horn and necrosis of surrounding tissues.
It is useful as a surgical tool for cutting and separating hard bone tissue, etc.
