Abstract

The invention relates to minimally invasive bone harvesting equipment used for the treatment of spinal surgery and various orthopedic operations. The traditional bone harvesting operation causes big surgical trauma and an evident skin scar and the appearance is affected after a large bone is taken out. The minimally invasive bone equipment is a set of medical apparatus, which comprises a circuit-opening bone harvesting drill, a bone harvesting drill and an auxiliary bone harvesting drill. The invention also comprises an abrasion drill, a bone chisel, a spatula and a drag hook. The bone harvesting drill comprises a drill rod and a bone-pushing rod. The drill rod is a round rod provided with an inner bore that is a straight hole. The front end of the drill rod is provided with a cutting edge. The bone-pushing rod is the solid round rod sheathed in the inner bore. The bone harvesting drill, and the like, needs to be installed on an electric drill or a manual handle when in use. The minimally invasive bone harvesting equipment is applicable to taking out the bone manually or electrically and has easy and safe operation, which is the novel, safe, efficient and convenient minimally invasive bone harvesting equipment and the pathology biopsy equipment for sclerotin and marrow.

Description

technical field [0001] The invention relates to a minimally invasive bone harvesting device in orthopedic surgery, in particular to a minimally invasive bone harvesting device with small wounds, small incision marks, avoiding postoperative bone defect deformity and preventing postoperative complications. Background technique [0002] In spinal surgery and a variety of orthopedic operations, it is often necessary to remove good bone graft materials from the patient's body, and autologous cancellous bone graft is the best bone graft material clinically proven. The traditional method of bone extraction is to use a chisel to knock out chunks of bone from the patient's bone. The surgical trauma is large and the skin scars are obvious. After a large piece of ilium is removed, the defect can affect the appearance. In addition to complications such as hematoma and infection in the bone harvesting area in the early stage, more than 30% of patients suffer from pain in the bone harvest...
