Abstract
The invention provides an intramedullary nail sighting device and a surgical instrument box comprising the same, and belongs to the technical field of surgical instruments. The intramedullary nail sighting device comprises a near-end sighting module, an adjusting module and a far-end sighting module which are connected in sequence; the adjusting module comprises a first adjusting block and a second adjusting block; a near end of the first adjusting block is connected with the near-end aiming module, a far end of the first adjusting block is rotatably connected with a near end of the second adjusting block, and a far end of the second adjusting block is connected with the far-end aiming module. The intramedullary nail sighting device is simple in structure and convenient to use, can rotatewhen sighting a far end of an intramedullary nail, and can meet sighting of holes of various angles of the intramedullary nail. In addition, the intramedullary nail sighting device is stable in structure and detachable, and can be connected with the far-end sighting module according to operation requirements. can adjust a rotation angle and upper and lower positions of the intramedullary nail, andcan meet various needs of people with different heights, people with different bone structures and bending.
Description
technical field [0001] The invention belongs to the technical field of surgical instruments, in particular to an intramedullary nail aimer and a surgical instrument box containing the same. Background technique [0002] Extremity surgery accounts for a large proportion of orthopedic trauma surgery. In order to facilitate the operation of doctors, some special instruments will be designed according to different types of surgery to save operation time and help doctors complete the operation better. [0003] Intramedullary fixation is currently widely used in orthopedic medical devices because of its advantages such as better control of the axial line of force. The intramedullary nail aimer is one of the surgical instruments used for intramedullary fixation, which can be used for external aiming, but the existing intramedullary nail aimer cannot rotate when aiming at the distal hole of the intramedullary nail, resulting in some locking of the intramedullary nail The aiming ope...
