Contact laser scalpel has been proved to have many advantages over the traditional non-contact ones since it was first proposed and applied in laser surgery in the middle of 1980's. In order to adapt to different clinical applications and achieve optimum curative effect, the emergent power distribution of the contact laser scalpels is crucial, which highly depends on the construction of the contact probes. By means of the development of restraint equations of light propagation in contact laser scalpels, a design scheme for such scalpels is presented. The coupling problems in different parts of the scalpels are considered carefully and their related construction is determined. In addition, because we generally can not describe the emergent power distribution of a contact laser scalpel in an analytic formula, the Monte Carlo method is introduced to simulate the behavior of light transmitting through the scalper. The simulation results are consistent with those of the experimental measurements. Different design parameters that effect the emergent power distribution are also discussed comprehensively.
