Fixing and binding band for femoral lesser trochanter bone fracture reduction

Abstract

The invention discloses a fixing and binding band for femoral lesser trochanter bone fracture reduction. The band comprises a plurality of metal wires, the front and rear ends of the metal wires are woven to form binding band bodies, the middles of the metal wires are woven to form a fixing lantern ring, the binding band bodies are formed by twisting all the metal wires into a strand, the fixing lantern ring is formed by twisting the middle metal wires into two strands, and the metal wires are made of peptide alloy materials; a locking buckle is arranged on the binding band and comprises a main locking buckle body, the main locking buckle body is provided with two axial through holes, the inner side of the main locking buckle body is provided with four claws, and the binding band bodies atthe two ends are matched with the two through holes one to one; the cross section of the main locking buckle body is arc. The fixing and binding band has the advantages that the band is simple in structure and convenient to use and operate, the surgical traumas of patients are effectively alleviated, it is effectively ensured that the lesser trochanter cannot be displaced again due to binding looseness, the influence on the blood supply of the femoral shaft is small, the production cost is low, and the surgical cost of the patients is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of medical aids, in particular to a binding belt for reduction and fixation of lesser trochanter fractures. Background technique [0002] Intertrochanteric fracture is one of the most common fractures, more common in the elderly, often accompanied by lesser trochanter fracture. In recent years, with the extensive development of various internal fixation operations and the improvement of the diagnosis and treatment of perioperative coexisting diseases, the mortality rate has been greatly reduced, but complications such as coxa varus, nail plate fracture, femoral head and neck cutting, and shortening of lower limbs have decreased. Still exist. In order to prevent or reduce the above complications, the importance of reduction and fixation of the lesser trochanter has attracted more and more attention. [0003] Fracture of the lesser trochanter, due to local ligament attachment, is difficult to reset a...

AI Technical Summary

Problems solved by technology

The above-mentioned surgical method will inevitably incise a relatively large area of ​​muscle, which will increase the trauma and blood loss of the patient. It is also difficult to reset the fractured and displaced lesser trochanter. The integrity of the proximal medial column is difficult to maintain, and the internal fixation of intertrochanteric fractures is prone to failure; at the same time, due to osteoporosis, the fixation with screws is not reliable and the trauma is large; the drilling wire binding is likely to cause secondary damage, and the wire will The smaller trochanter is cut off; when the metal wire is directly tied on the outer surface of the smaller rotor, it is also difficult to penetrate the metal wire around the smaller rotor, and the metal wire is easy to slide off the outer surface of the smaller rotor, which cannot be fixed; at the same time, the above two After being bound with this kind of metal wire, the blood circulation on the femoral stem and femoral membrane will not be smooth, which will affect the healing of the wound and may cause tissue necrosis at the place
