Description

Digital femur neck guide pin mechanical navigation sighting device

Technical Field

The utility model belongs to the technical field of femoral neck fracture positioning instrument, concretely relates to digital femoral neck guide pin mechanical navigation sight.

Background

The fracture of the neck of femur is common in clinic, especially the fracture of the neck and the tuberosity of the femur of the elderly. The hollow nail or DHS is a common treatment method, when the screw and nail plate system is used for fixing the femoral neck fracture or intertrochanteric fracture, a femoral neck guide needle is firstly driven, and the neck angle and the anteversion angle are mainly controlled by the guide needle. At present, an accurate and simple aiming device is controlled for the neck and trunk angles of a guide pin, and the control for the front rake angle still stays on the basis of empirical judgment; in addition, when the femoral neck fracture is fixed by the hollow screw, the positions of the three guide pins need to be adjusted for many times in the operation, and the mutual parallelism is difficult to ensure, which becomes an operation difficulty. Because the femur neck has special anatomical structure, the cervical shaft angle and the anteversion angle exist on different planes, and the positions are deep and hidden, so that the positioning guide pin has certain difficulty in being correctly placed. When the internal fixation is used for treating the fracture of the femoral neck and the femoral tuberosity, a guide needle is firstly placed for positioning. Usually, the guide pin is inserted according to the clinical experience of the doctor, and after each needle insertion, the C-arm machine is required to perform fluoroscopy to check whether the guide pin is in place, but the positioning guide pin cannot be correctly inserted because the needle insertion point or the upper or lower deviation, the front rake angle and the cervical shaft angle are not well mastered.

In recent years, many scholars have designed some surgical instruments and even applied computer aided navigation systems. In the similar apparatus of design principle, the fixed point pjncture needle needs to puncture to femoral head central point, and the reduction of fracture of femoral neck fracture patient mostly needs to maintain the rotatory position in the lower limb, and this point is buried by the acetabulum at this moment, is difficult to puncture, and this point is close to abdominal cavity and femoral vascular nerve, these important tissues of easy puncture. When the conventional DSH angle guider is used, after the guide pin is drilled in the operation, if the guide pin is found to be upward or downward, the guide pin needs to be taken out, and after the guide pin is adjusted, the guide pin is drilled in again, and if the guide pin is not satisfactory, the operation needs to be repeated again. Resulting in repeated needle insertion, iatrogenic damage to the patient and radiation damage to the patient and the medical staff caused by repeated C-arm machine fluoroscopy.

Therefore, the main problem of restricting the operation is that the nail implanting difficulty in the femoral neck is the main problem, the traditional operation method is that firstly the guide needle is used, whether the perspective position is proper or not is difficult to succeed once, the operation time needs to be adjusted repeatedly, blood circulation is damaged by repeatedly threading the needle in the femoral neck, the fixing strength of the femoral neck is reduced, healing is affected, the probability of femoral head necrosis is increased, and the influence of rays on patients and doctors in repeated perspective is increased.
