Abstract

The invention discloses a gear type universal shaft connection anti-blocking acetabulum filing and cup placing self-locking mechanism rod. The gear type universal shaft connection anti-blocking acetabulum filing and cup placing self-locking mechanism rod comprises a tubular shell, wherein the shell comprises a first shell section, a second shell section, a third shell section, a fourth shell section and a fifth shell section; the first shell section and the fifth shell section are vertically distributed, and the second shell section, the third shell section and the fourth shell section are located on the same side of the fifth shell section; the second shell section is obliquely distributed upwards, and the fourth shell section is obliquely distributed downwards; a first shaft section is arranged in an inner cavity of the first shell section, and a second shaft section is arranged in an inner cavity of the second shell section; the first shaft section and the second shaft section are connected through a universal coupling; a fifth shaft section is arranged in an inner cavity of the fifth shell section; the first shaft section and the fifth shaft section extend to the outside of theshell; and the fifth shaft section is used for being connected with an axial stabilizing mechanism; and the fifth shell section is sleeved with a check ring. According to the gear type universal shaft connection anti-blocking acetabulum filing and cup placing self-locking mechanism rod, the shell is provided with a bent part, so that the shell can avoid the human body part during an operation, and the normal operation of the hip joint operation is not influenced.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, and in particular to a gear type universal joint shaft preventing and blocking acetabular grind file and a cup setting self-locking mechanism rod. Background technique [0002] In recent years, more and more patients undergo orthopedic hip surgery. Among them, some patients need to undergo acetabular cup replacement, and the operation method is: use an acetabular file to grind off the diseased bones of the human hip joint, and then install the acetabular cup. During the operation, the acetabular file is connected to the connecting rod. The connecting rod penetrates the axial stabilization mechanism. The end of the connecting rod is connected to the power tool. The power tool generates continuous rotational power. The acetabular file uses the axis of the connecting rod as the center of rotation. Rotate quickly to grind away the diseased bone tissue. When the acetabular cup is installed, the...
