Abstract
The utility model discloses a kind of medical anti-rotation and hold rod device, this is held rod device and includes holding rod main body and holding the pressure bar bolt of excellent main body with holding the rod handle that is connected of main body upper end and being positioned at of tubulose, described rod main body end of holding connects one with the spheroid of through hole, and the bottom of spheroid is provided with groove.Owing to have employed said structure, pressure bar bolt, band through hole spheroid bottom groove and pitman be three-point contact structure, pitman is had firm hold, and there is good anti-rotation effect.
Description
Technical field
This utility model relates to medical equipment technical field, particularly relates to a kind of medical anti-rotation and holds rod device.
Background technology
Medical apparatus and instruments is the key factor that can impact operation be smoothed out, and therefore requires the strictest to the properties of medical apparatus and instruments.Especially in anti-rotational apparatus, as currently used holds rod device, generally there is the clamping force to pitman inadequate, during operation technique, pitman is fixed insecure, easily rotates, and not only affects the progress of operation, returns patient and adds unnecessary misery.To this end, our continuous summing up experience in practice for many years, devise a kind of medical anti-rotation and hold rod device, preferably resolve pitman in operation, fix unstable problem.
Summary of the invention
The purpose of this utility model is to provide a kind of medical anti-rotational holds rod device.
The purpose of this utility model is achieved through the following technical solutions, this medical anti-rotational rod device of holding includes holding rod main body and holding the pressure bar bolt of excellent main body with holding the rod handle that is connected of main body upper end and being positioned at of tubulose, described rod main body bottom of holding is provided with female thread, its end connection one is with the spheroid of through hole, the bottom of spheroid is provided with groove, the upper end of described pressure bar bolt is provided with hexagonal (hexagon)nut, and lower end is provided with the external screw thread matched with the female thread holding rod main body lower end.
Using method: after pedicle screw is all implanted, one end of pitman is put into and holds the spherical shell that rod device is with holes, screw pressure bar bolt, patient holds handle and is pushed by pitman, while push edge axial-rotation, insert pitman smoothly, use the position holding rod device maintenance pitman, be screwed into jackscrew and fix.
The beneficial effects of the utility model: owing to have employed said structure, pressure bar bolt, band through hole spheroid bottom groove and pitman be three-point contact structure, pitman is had firm hold, and having good anti-rotation effect, patient holds during pitman pushes by handle, can rotate vertically, pitman can be inserted smoothly, can be used for Minimally Invasive Surgery, can also be used for open surgery, when especially multi-segmental being rebuild, more can embody its superiority.
