- the procedure can be performed by installing an artificial knee joint (implant) according to a set sequence.
- the sleeve (1) according to the present invention is not composed of a thin and long pipe as in the prior art, but is relatively Since it is composed of a hollow sleeve body (11) with a large outer diameter, the sleeve is not replaced every time the cutter type is changed, and as shown in Figures 7a to 7c, a cutter with a head diameter of 3.2mm, a cutter with a head diameter of 5.0mm, a cutter with a head diameter of 6.2mm, etc. It can be easily replaced and used.
- the surgical device for a surgical robot equipped with a calibration mounting unit includes a calibration tool (7b, calibration tool) such as a marker for calibrating the end of the cutter in the artificial joint surgery process using a robot, and a calibration mounting unit (4). It can be installed easily.
- the pin insertion groove 441 formed in the sleeve 1 has a foreign matter discharge portion, which is a part exposed to the outside by cutting the outer part, so even if foreign matter generated by the operation of the cutter during surgery is introduced, it is easily discharged to the outside. There is an advantage to this.
- an inspection opening 415 is formed in the fixing cap member 41, a gap is created when foreign matter flows between the inner surface of the positioning member 422 and the end of the sleeve 1, so the gap can be confirmed with the naked eye. If possible, calibration can be performed accurately by separating the fixing cap member 41 from the sleeve 1, performing a cleaning operation, and then reassembling it.
- the present invention is a surgical device for a surgical robot equipped with a calibration mounting unit that can be applied to artificial joint surgery using a robot.
- the present invention can be applied to various surgical robots in the medical field, allowing for compatible installation and use of medical tools and calibration.
- the tool can be easily installed and used for accurate calibration.
