The invention discloses a hole broadening device for the department of orthopedics and relates to the technical field of medical equipment. The hole broadening device comprises a base, a sliding rod, fixed rods, connecting rings, a hole broadening head and a push rod. The sliding rod is arranged at the bottom of the inner side wall of the left end of the base in the horizontal direction. The bottom of each fixed rod is provided with a horizontal sliding slot. The sliding rod is connected with the fixed rods through the sliding slots. The upper end of each fixed rod is provided with a through hole. The edge of each through hole is provided with a connecting slot. One side of each connecting ring is provided with a connecting groove, and the other side of each connecting ring is provided with a connecting protrusion. Each connecting protrusion is arranged in the corresponding connecting groove. The hole broadening head is connected to the inner side wall of the right end of the base through the push rod. The hole broadening device for the department of orthopedics is simple, reasonable, easy to operate, good in machining effect, low in cost, small in shape, safe and convenient to use, stable in performance and high in efficiency.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a hole reaming device for orthopedics. Background technique [0002] At present, with the development of non-invasive and minimal pain medical technology, orthopedic medical devices have been greatly improved and developed; for example, bone drills, stainless steel casings for bone drills, and bone cement syringes have played a huge role in the rehabilitation of patients. From the perspective of medical safety and environmental protection, the bone drill bit, the tip of the stainless steel sleeve, and the end of the syringe all need to be protected, and the PC protective sleeve for medical use is the best choice, but the tapered mouth of the tube is not easy to be cold-formed. [0003] Existing hole reamers are of various types and simple in structure, and are mostly used for metal pipes and thermosetting plastics, but few of them can be used for pipes made of thermopla...
