The femoral head necrosis needs interventional operation treatment in the early stage of collapse, so that the femoral head is reserved to the maximum extent, and further collapse and injury are avoided. The core drilling decompression operation is to thoroughly remove the necrotic bone tissue of the femoral head, and at present, the necrotic bone tissue is mainly cleaned by a Kirschner wire and a bone drill matched with an elbow curet. Because of the hardening of necrotic bone tissue and the limited scope of the passage, often a portion of necrotic bone tissue remains, the femoral head is not completely depressurized, thereby affecting the surgical effect. The embodiment provides a femoral head necrosis core decompression device, as shown in fig. 1, which comprises an outer guide tube 1, an inner guide tube 2 and a soft drill bit assembly 3, wherein the outer guide tube 1 and the inner guide tube 2 jointly act on the soft drill bit assembly 3 to play a guiding role, and the soft drill bit assembly 3 is used for destroying and removing the femoral head necrosis bone tissue.
As shown in fig. 2, the outer guide tube 1 is a straight tube, which is beneficial for the outer guide tube 1 to extend into the femoral head necrosis area; an operating handle 11 is arranged at one end of the outer guide tube 1 far away from the bending section 22, so that the insertion operation of the outer guide tube 1 is facilitated; preferably, the inner diameter of the outer guide tube 1 is 8-16mm. As shown in fig. 3, the inner guide tube 2 includes a straight tube section 21 and a bent section 22 connected to each other, and the bent section 22 is offset to one side of the straight tube section 21 by a certain angle. The bent section 22 extends into and out of one end of the outer guide tube 1 and the other end of the outer guide tube 1, the inner diameter of the outer guide tube 1 being dimensioned such that the bent section 22 extends into and out of the outer guide tube. The inner guide tube 2 is used for guiding the soft drill bit assembly 3, and the bending section 22 greatly expands the operation range of the soft drill bit assembly 3, so that necrotic bone tissues are removed more thoroughly. The end of the straight pipe section 21, which is far away from the bending section 22, is provided with an operating handle 23, which facilitates the insertion operation of the inner guide pipe 2. The transitional connection part of the straight pipe section 21 and the bending section 22 is a smooth circular arc. The straight tube section 21 has the same inner diameter as the bent section 22, and the inner diameter of the inner guide tube 2 is preferably 6-14mm.
As shown in fig. 4, the soft bit assembly 3 includes a bit 31, a soft drill rod 32 and a hard drill rod 33 connected in sequence, the bit 31 passing through the straight pipe section 21 and extending out of the bent section 22. The soft drill rod 32 is a soft shaft rod or a spring drill body, and the soft drill rod 32 can be bent into different forms, so that the drill bit 31 can be adjusted to work at different angles, and the drill bit 31 can conveniently extend into the bending section 22 of the inner guide tube 2; the two ends of the soft drill rod 32 are in threaded connection or clamping connection with the drill bit 31 and the hard drill rod 33; the hard drill rod 33 may be a metal hard rod that facilitates entry of the drill bit 31 assembly into the inner guide tube 2. The end of the hard drill rod 33 is connected to an electric drill which is capable of rotating the hard drill rod 33, the soft drill rod 32 and the drill bit 31.
In order to prevent the drill bit 31 from being drilled too deeply into the femoral head tissue, the outer surface of the hard drill rod 33 is provided with a stop 331, the outer dimension of the stop 331 being larger than the inner diameter of the straight pipe section 21. The hard drill rod 33 and the limiting piece 331 may be integrally formed or detachably connected. External threads can be arranged on the hard drill rod 33, internal threads are correspondingly arranged on the limiting piece 331, and the hard drill rod 33 is in threaded connection with the limiting piece 331. To facilitate determination of the penetration depth of the drill bit 31, the outer surface of the hard drill rod 33 is provided with graduations 332. The drill bit 31 includes a drill rod body 311, a pointed drill bit 312 and a round drill bit 313 which are sequentially disposed on the drill rod body 311 from front to back. Because the necrotic bone tissue may be hardened, the front end of the drill rod body 311 is provided with a pointed drill bit 312, and the pointed drill bit 312 is triangular or conical, so that the drill rod is beneficial to drilling the hardened necrotic bone tissue; the rear end of the round grinding bit 313 is spherical, and sharp grinding particles are uniformly distributed on the circumferences of the pointed bit 312 and the round grinding bit 313 and are used for grinding necrotic bone tissues. The diameter of the round grinding bit 313 is 3-4mm.
The working procedure of this embodiment is: as shown in fig. 5, the necrotic area was confirmed preoperatively by CT; drilling to a femoral head 4 necrosis area through a Kirschner wire under the assistance of a C-arm machine, wherein the femoral head is 5mm below cartilage; drilling a bone tunnel along a Kirschner wire through a hollow drill bit; the outer guide tube 1 is inserted under the necrosis area of the femoral head firstly, then the inner guide tube 2 is inserted, and the operation handle 23 of the inner guide tube 2 is rotated to adjust the bending section 22 to the area with large necrosis area; the soft drill bit assembly 3 is inserted, the tail end of the hard drill rod 33 is connected with an electric drill, the drill is drilled through the drill bit 31, and the dead bone is thoroughly removed by matching with an elbow curette.
According to the femoral head necrosis core decompression device provided by the embodiment, the bending section can extend out of the outer guide tube, the drill bit penetrates out of the bending section, the operation range of the drill bit is enlarged, necrotic bone tissues are effectively and thoroughly cleared, and full decompression is facilitated; the direction of the bending section is adjusted by adjusting the direction of the inner guide tube, so that the operation range of the drill bit is flexibly adjusted, the necrotic bone tissue of the femoral head is further and fully and effectively removed, and the perspective times of a C-arm machine in operation are greatly reduced; the drill bit is driven by the electric drill to remove necrotic sclerotin, so that the operation is more convenient and quicker, the operation speed is accelerated, and the operation effect is improved.
