Provided herein are surgical guides with internal channels for irrigation cooling. In one embodiment, an apparatus for guiding a surgical instrument includes a proximal side and a distal side. A first channel is configured to guide a material removal device, where the first channel extends from the proximal side of the apparatus to the distal side of the apparatus. A second channel configured to direct irrigation fluid, where the second channel extends from the proximal side of the of the apparatus to the distal side of the apparatus. The first channel is separate from the second channel. A method of performing a surgical procedure and a method of manufacturing a surgical guide are also disclosed. In certain embodiments, the surgical guides may be manufactured via additive manufacturing processes, including for example, three-dimensional printing processes.

A device for intrabody surgery comprises a cutting arrangement rotatable by a hollow driveshaft, which is formed by a hollow front cutting region and a rear region. The front region includes multiple longitudinal drilling sections interconnected by transversely oriented cutting blade sections. The drilling sections are positioned at an angle to each other defining in combination with the cutting blades a conically shaped grid formation having a hollow internal cavity. The grid formation defines a plurality of ports between the drilling sections and the blades. A low-pressure zone is formed within the hollow internal cavity, wherein cut occlusion materials are aspired by the low-pressure zone through the plurality of ports into the hollow internal cavity for further evacuation from the cutting arrangement.

A medical drill assembly includes a probe connectable at a proximal end to an electromechanical transducer for generating mechanical vibration of an ultrasonic frequency. The probe has a shaft with a central lumen or channel, the shaft being formed at a distal end with a head having a tapered distal side. A source of pressurized liquid communicates with the lumen or channel of the probe, and a translatory or linear drive is operatively connected to the probe for applying a distally directed force to the probe. A controller is operatively connected to the translatory or linear drive for periodically at least reducing the magnitude of the distally directed force.

A tool for a bone implant includes a sleeve and a transmission rod including a transmission member disposed on an end of a shaft. Another end of the shaft is located outside of the sleeve. The transmission member is received in the sleeve and includes a first compartment and a plurality of first teeth surrounding the first compartment. A drilling rod includes a second compartment and a plurality of second teeth surrounding the second compartment. A coupling portion is disposed between the second compartment and a bit. The coupling portion is coupled with the sleeve. The bit is located outside of the sleeve. Two magnets are disposed in the first and second compartments, respectively. Two same poles respectively of the two magnets face each other.
