Detailed Description

As shown in fig. 1-6, a phalanx stump polisher comprises a polishing main body 1, wherein a polisher connecting rod 2 is fixedly connected to the upper portion of the polishing main body 1, the polisher connecting rod 2 is connected with a bone drill, a plurality of leakage holes 3 are uniformly formed in the surface of the polishing main body 1, a plurality of polishing plane blades 5 are uniformly arranged inside the polishing main body 1, and a positioning pin 4 is arranged in the middle of the polishing main body 1; the sander connecting rod 2 is fixed on a drill bit of a bone drill and conducts power to enable the sanding main body 1 to dress the finger bone at the residual end; the bone residues ground in the polishing process can be discharged by arranging the plurality of leakage holes 3, so that the polishing work is prevented from being influenced; the positioning pin 4 is a short and thin positioning pin, when the polishing surface of the polishing main body 1 covers the bone stump, the finger bone stump and the polishing main body 1 are extruded, the positioning pin 4 can stabilize the finger bone stump and the polishing main body 1, the polishing main body 1 can be polished to form a smoother curved surface under the stabilizing effect, excessive polishing of the finger bone stump in one direction can possibly occur without the fixing effect of the positioning pin, and as a result, the finger bone stump can be polished for multiple times, the shortening degree of the finger bone stump is increased, so the positioning pin 4 can reduce excessive shortening of the finger bone stump, and the short and thin positioning pin can reduce excessive damage to bones of the finger bone stump; the finger bone stump grinding tool is simple in structure and convenient to use, is applied to finger bone stump end surfaces with different thicknesses according to different models of grinding bodies, avoids the problems of skin top ulceration infection, stump pain and the like caused by unsmooth occlusion of the traditional rongeur, and is smooth and flat in ground finger bone stumps and beneficial to wound recovery.

Particularly, the polishing main body 1 is in a hemispherical shape or a circular truncated cone shape, and can polish the phalange stump into a hemispherical shape or a circular truncated cone shape, so that the binding is facilitated, and the healing speed can be increased; as shown in fig. 6, the grinding plane blades 5 are uniformly arranged on the inner wall of the grinding main body 1, the grinding plane blades 5 extend outwards in an arc shape from the center of the grinding main body 1 to form an involute spiral cutting edge, and the involute spiral cutting edge forms a spiral grinding plane blade array; when the cutting edge is rotated, the gradually-opened spiral cutting edge can better polish the residual end face of the phalanx, and the polishing efficiency is improved.

The quantity of small opening 3 sets up to four and evenly distributed, and the position of the quantity of small opening 3, aperture and trompil all can design according to actual demand to satisfy the in-service use demand and be the standard.

The surface coating of sander connecting rod 2 has the antiskid coating, prevents to appear skidding the phenomenon between sander connecting rod 2 and the bone drill in the use.

The polishing main body 1 and the polisher connecting rod 2 are both made of medical titanium steel materials.

In the first embodiment, as shown in fig. 1 and 2, the sander connecting rod 2 is a triangular prism, which is convenient to be fixed on a drill chuck of a bone drill for operation, and can prevent rotation and improve stability.
