This utility model compared with prior art beneficial effect is:

Described holotomia device, first detent mechanism is retracted, foot is stretched into framework, clavus is aimed at the center of detent mechanism, unclamp detent mechanism, foot is fixed by detent mechanism and by the meat of clavus surrounding to pressing down, make clavus outstanding relative to Other Meat, the range estimation clavus degree of depth, because of handle of a knife and cutter hinged, the angle of adjustable handle of a knife and cutter, to ensure depth of cut, then by handle of a knife and the hinged of rotary connector, cutter are cut, then utilize rotary connector to rotate to cut, after cutting is lower, if do not cut to the root of clavus, the angle continuing adjustment handle of a knife and cutter is cut, avoiding medical personnel uses hands to pin the foot portion of patient, and whole clavus can be bloated by detent mechanism, avoid and cut some handss and move a position, disposable clavus can be cut, cutting efficiency is high, and avoid medical personnel's hands and touch patient's foot portion, avoid hands infected fungus when not wearing glove, safe and reliable.

Described detent mechanism, spring is connected between side and baffle plate with framework at shell, is drawn by locating rod so hold handle outside framework, meeting Compress Spring, when foot is stretched into framework by patient, and allow clavus be positioned at scope corresponding to centring ring, unclamp handle, spring can drive locating rod to talk, until be subject to the stop of foot, the meat of clavus surrounding can be depressed by locating rod under the drive of spring, clavus is protruded, then carries out cutting.

Described sleeve pipe, handle of a knife can be shuttled back and forth in sleeve pipe, to coordinate the cutting angle between cutter and handle of a knife to reach the cutting of foot to any size and any degree of depth, when foot is less, handle of a knife inwardly can be pushed away, after ensureing cutter and handle of a knife angular adjustment, cutter can be entered in the angle be applicable to, ensure that the patient of any foot type is all on probation, and frosted layer is handle of a knife provides damping, ensures that handle of a knife can not move in use.

Described detent mechanism number, two detent mechanisms can have two acting force of the spring to be pressed by the meat of clavus surrounding, make clavus outstanding more obvious, very reliably, reduce cutting difficulty.

Described sleeve pipe number, two cutter that two handle of a knifes are installed are relative, carry out circumgyration incision like this, more fast, can improve cutting efficiency.
