Description
Technical Field
The invention relates to the field of medical equipment, in particular to a sleeve device for a tibia intramedullary nail of a patella upper access.
Background
In recent years, because the intramedullary nail of the tibia has the advantages of being minimally invasive, high in fixing strength, capable of moving immediately after operation and the like, the application of the intramedullary nail to treat the fracture of the shank shaft becomes the preferred scheme of orthopedics doctors. The current operation access for fixing and treating tibia fracture by intramedullary nails mainly comprises a patella lower access and a patella upper access. The patella lower approach has the advantages of small wound, simple operation, easy acceptance by patients and the like, has wide clinical application, is difficult to maintain an ideal position in operation, has certain deformity, is difficult to perspective in operation, and is more common in postoperative knee pain. The patellar access is used as a novel operation access, and has the advantages of being beneficial to fracture reduction and maintenance, convenient in perspective in operation, low in incidence rate of postoperative gonalgia and the like. The patient is in supine position during the patellar access operation, the affected limb is in semi-straightened position, the operation incision is generally a longitudinal incision which is about 3-4cm long and is made from the upper pole of the patella to the proximal end of the limb on the median line of the patella, the femoral quadriceps tendon is separated in a sharp way after that, the joint capsule is opened from above the patella, a special hollow sleeve for the patellar access is inserted, and the protective sleeve is used for ensuring that the proximal end of the tibia reaches the optimal needle insertion point along the trochanter groove of the femur.
In actual clinical practice, patellar access tools present some problems. (1) Existing patellar access tools on the market are designed with western anatomy. Because the Chinese physique is smaller, the patella space is smaller, and the patient can encounter larger resistance when the protective jacket is inserted in the operation, the risk of iatrogenic injury to the intra-articular structure exists, the implantation of the positioning guide needle is influenced, and the operation time is prolonged. (2) The existing protective jackets on the market are round, while the patellofemoral joint is V-shaped, which are not well matched in shape. When the pressure of the patellofemoral joint is high, the patella slides to one side, and the sleeve slides to the opposite side. (3) The opening and reaming can produce a significant amount of debris that remains in the joint cavity with serious consequences such as knee pain, cross-locking, and even destruction of intra-articular structures, so thorough post-operative cleaning is necessary. But the operation channel of the access on the patella is a relatively closed environment, and the operation channel can not be thoroughly washed like the open operation such as knee joint replacement operation and the like. How to wash the scraps clean and reduce the foreign matter residues in the joint cavity becomes a relatively troublesome but non-negligible problem for the upper patellar approach.
