In addition, the scalpel in the embodiment of the invention is also provided with the cutter head 8 capable of adjusting the laser emission quantity on the near infrared optical fiber limiter 3, so that the effect of adjusting the laser emission temperature is realized only by the cutter head 8, and the patient is prevented from being burnt.
Further, as shown in fig. 2, the cutter housing 1 in the present embodiment includes a housing 4 with two open ends, and the housing 4 is cylindrical, but may also have other shapes, such as a square cylinder, etc.; the connector 5 is detachably arranged at the first end of the shell 4, the connector 5 is simultaneously communicated with the limiting space, and the fixed connector 2 is arranged at the second end of the shell 4.
Specifically, the connector 5 in this embodiment is screwed or fastened to the housing 4. In the case of fastening, it is preferable to provide the connector 5 and the housing 4 with a matching concave-convex structure, so as to increase the connection firmness. Further, the fixing connector 2 in the present embodiment is in a cap shape, which is also fixed on the housing 4 in a screwing or buckling manner, and similarly, when the fixing connector 2 and the housing 4 are in a buckling manner, it is preferable to correspondingly provide matched concave-convex matching structures so as to increase the connection firmness. A limiting portion for limiting the near infrared optical fiber is also formed in the fixed connector 2, and the structure of the limiting portion is not unique, so long as the fiber can be fixed.
With continued reference to fig. 2, the first end of the housing 4 in this embodiment has a first limiting portion 6, the near-infrared fiber limiter 3 has a second limiting portion 7 capable of cooperating with the first limiting portion 6 to limit the near-infrared fiber limiter 3, and when the first limiting portion 6 and the second limiting portion 7 cooperate, the near-infrared fiber limiter 3 extends out of the connector 5 with a fixed length toward one end of the connector 5. That is, the end of the near infrared optical fiber limiter 3 provided with the cutter head 8 extends out of the connector 5 with a fixed length.

Continuing with fig. 2, the end of the near infrared fiber limiter 3 extending out of the connector 5 in this embodiment is wedge-shaped, that is, the end of the near infrared fiber limiter 3 provided with the cutter head 8 is wedge-shaped. Moreover, the outer edge of the wedge-shaped end is curved to increase the fixing force to the cutter head 8, and the outer shape of the cutter head 8 can be adjusted, so that the cutting range can be adjusted. Of course, the port may be in a shape of a common circle, square, etc., and the outer edge may be linear or circular arc, etc.
Preferably, the tool bit 8 in this embodiment is a gemstone tool bit 8, such as sapphire, ruby, sapphire, quartz, etc. The light transmittance of the setting material of the cutter head 8 is matched with the wavelength of the near infrared laser emitted by the near infrared optical fiber,
the material of the precious stone at least needs to meet the requirements of transmitting laser and shielding some laser at the same time, so as to achieve the effect of reducing the laser depth which cannot be controlled when the laser is emitted.
In addition, a lens can be arranged in the cutter head 8 so as to correct and reduce the beam divergence effect through the lens effect, and the beam auxiliary operation is easy to control.
In addition, the shape of the cutter head 8 is not unique, and for example, the cutter head 8 can be a round head cutter head for quickly vaporizing human tissues, or the cutter head 8 can be a flat head cutter head for coagulating wounds to stop bleeding, or the cutter head 8 can be a conical cutter head for surgical cutting and the like.
