Technical Field

The invention relates to the technical field of femoral operation puncture positioning, in particular to a detachable spherical handle.

Background

The femur, the largest long tubular bone in the human body, can be divided into two integral ends. The upper end of the hip joint is inward and upward, and the tail end of the hip joint is expanded to be spherical and called as the femoral head. A small recess, called the femoral head recess, is located slightly below the center of the head and is the attachment of the femoral head ligament. The thinner part of the head below the outside is called the femoral neck. The angle between the neck and the body is called the angle of the neck trunk, which is 132 degrees for men and 127 degrees for women. The outside of the junction of the neck body is provided with an upward bulge called as a greater trochanter, and the smaller bulge at the inner lower part of the neck body is called as a lesser trochanter. The inner side of the greater trochanter is provided with a depression called a trochanter pit (also called a pear-shaped pit). Between the big and small rotors, there is a rotor line in front and a rotor ridge in the back. Between them, it is called as the intertrochanteric femoral region, where fractures occur frequently. The femur is the longest, most solid, long bone of the human body, and its length is about 1/4 angstroms.

The femoral operation puncture positioning is to puncture at a puncture point of the femur and puncture a puncture needle into the femur to extract a test substance; in summary, the purpose of puncturing is blood sampling, blood transfusion, fluid infusion, and catheterization for angiography; at present, the types of existing puncture positioning tools (such as a bone positioning needle, a bone probe, a bone drill and the like) are more, and besides a spherical handle tool, the existing puncture positioning tools also have a plurality of set tools; there may be a phenomenon of mistaking due to the large number.

Therefore, it is urgently needed to provide a detachable spherical handle with simple structure and simple installation.
