the trephine sleeve is sleeved outside the bone crushing rod, one end of the trephine sleeve is provided with cutting teeth, and the other end of the trephine sleeve is provided with a second handle;
the section of the trephine sleeve provided with the cutting teeth is close to one end of the broken bone rod provided with the positioning cone;
when the bone cutting device is used, after a channel is opened in a minimally invasive surgery, the second handle is held, a proper amount of bone and a bone disease stove are annularly cut in a rotating mode along the channel by the trephine sleeve, uneven bone is prone to occurring in a human body after a bone and femoral lesion is extracted, the positioning cone is positioned on the uneven bone, the broken bone rod is rotated, the uneven bone in the human body is cut, and the defects that the end face of the traditional trephine type bone taking rear end is uneven and the bone taking success rate is low are effectively overcome; when the trephine sleeve is matched with the broken bone rod for use, the centrum can be crushed and cut, and the spiral groove can temporarily store the crushed and cut broken bone.
Furthermore, the positioning cone and the bone crushing rod are coaxially arranged, so that the operation stability of the bone crushing rod is improved.
Furthermore, four groups of cutting edges are symmetrically arranged at the center of each cutting edge, so that the bone crushing efficiency is improved.
Further, the cutter teeth are disposed at one end of the trephine sleeve along an annular array.
Further, the length of the trephine sleeve is smaller than the length of the bone fragment rod.
Furthermore, the bone crushing rod and the positioning cone are detachably connected.
The beneficial effects of the utility model are that: compared with the prior art, the utility model discloses an internal garrulous bone cutting device has following advantage: after a channel is opened in a minimally invasive surgery, a second handle is held, a proper amount of sclerotin and a bone disease stove are annularly cut in a rotating mode along the channel through an annular drill sleeve, the irregular condition of sclerotin is easy to occur in a human body after the sclerotin and femoral lesions are extracted, the positioning cone is positioned on the irregular sclerotin at the moment, a broken bone rod is rotated to cut the irregular sclerotin in the human body, and the defects that the end face of the traditional annular drill type bone taking method is irregular and the success rate of bone taking is low are effectively overcome; when the trephine sleeve is matched with the broken bone rod for use, the centrum can be crushed and cut, and the spiral groove can temporarily store the crushed and cut broken bone.
Drawings
FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a schematic view of the present invention showing the structure thereof;
wherein, 1 trephine sleeve, 101 cutting teeth, 102 second handle, 2 broken bone rods, 201 spiral groove, 202 first handle, 203 cutting edge and 3 positioning cone.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention.
In the embodiment shown in fig. 1 and 2, an in vivo bone-crushing cutting device comprises a trephine sleeve 1, a bone-crushing rod 2 and a positioning cone 3, wherein:
one end of the bone crushing rod 2 is provided with a spiral groove 201, the other end of the bone crushing rod is provided with a first handle 202, one end, far away from the first handle 202, of the spiral groove 201 is provided with a cutting edge 203, and one end, provided with the cutting edge 203, of the bone crushing rod 2 is provided with a positioning cone 3;
the trephine sleeve 1 is sleeved outside the broken bone rod 2, one end of the trephine sleeve 1 is provided with a cutting tooth 101, and the other end of the trephine sleeve 1 is provided with a second handle 102;
one section of the trephine sleeve 1 provided with the cutting teeth 101 is close to one end of the bone crushing rod 2 provided with the positioning cone 3;
when the bone cutting device is used, after a channel is opened in a minimally invasive surgery, the second handle 102 is held, a proper amount of bone and a bone disease stove are circularly cut in a rotating mode along the channel by the trephine sleeve 1, the uneven condition of the bone is easy to occur in a human body after the bone and femoral lesions are extracted, the positioning cone 3 is positioned on the uneven bone at the moment, the broken bone rod 2 is rotated, the uneven bone in the human body is cut, and the defects that the rear end face of the traditional trephine type bone taking method is uneven and the success rate of bone taking is low are effectively overcome; when the trephine sleeve 1 is used in cooperation with the bone crushing rod 2, the vertebral body can be crushed and cut, and the spiral groove 201 can temporarily store crushed and cut bone.
In this embodiment, location awl 3 and the coaxial setting of garrulous bone pole 2 improve garrulous bone pole 2 stability in operation. Four groups of cutting edges 203 are symmetrically arranged at the center, so that the bone crushing efficiency is improved. The cutting teeth 101 are arranged at one end of the trephine sleeve 1 along an annular array. The length of the trephine sleeve 1 is less than the length of the bone fragment rod 2. The bone crushing rod 2 is in threaded connection with the positioning cone 3.
