Description

Femoral head operation area protective sleeve for dislocation access of hip joint surgery

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a femoral head operation area protective sleeve for dislocation access of hip joint surgery.

Background

The dislocation access of the hip joint surgery is a special hip joint surgery access, and the surgery type hip joint surgery access can turn over and cut bones through a femoral tuberosity, can generate a gap of at least llcm between a femoral head and an acetabulum while maintaining the integrity of main blood supply sources of an external rotation muscle group and the femoral head, and can deviate the femoral head from the front part to provide a 360-degree femoral head view for the implementation of surgery treatment operation. The operation type surgical treatment method is mainly used for surgical treatment of femoral head fracture, femoral head necrosis, hip joint impact syndrome, hereditary multiple osteochondrioma, fiber structure failure, chondroblastoma, benign hip joint synovial lesion and other diseases.

In the operation of dislocation approach of hip joint surgery, operators often perform operations such as a certain focus clearance or bone drilling and grinding and cutting in the diseased femoral head and femoral neck area according to the disease condition, so as to generate partial soft tissue fragments or bone fragments. After the femoral head is removed, a larger temporary cavity is formed in the lower acetabular fossa, and as the scraps enter the lower acetabular fossa, the difficulty in flushing and cleaning the acetabular fossa at the end of the operation can be increased. If the cleaning is not thorough, the broken bone fragments after operation can remain in the hip joint, so that the discomfort of the hip after operation of a patient is caused, and the rehabilitation after operation of the hip joint is affected. There is currently no specific solution or tool for this problem in the clinic. To avoid such debris from entering the underlying acetabular fossa, the surgeon often chooses to temporarily tamponade the base portion of the emerging femoral neck with multiple pieces of gauze to form a barrier. However, the blockage of the tamponade of the gauze does not completely avoid this problem, and the debris attached to the gauze may still fall into the joint cavity when the gauze is removed. Meanwhile, gauze filling and blocking are inconvenient for operation. In addition, the main operation area of the operation type is positioned on the femoral head and the periphery of the femoral head, but in order to realize the exposure of the femoral head, the incisions of skin and soft tissues are large, the operation is long, the infection risk is large, the soft tissue incisions needed by the operation is not temporarily protected, and the reduction of the infection risk is facilitated.

The femoral head operation area protective sleeve for the dislocation access of the hip joint surgery is characterized in that an adhesive tape with a protective film is arranged on the peripheral surface of the upper end part of the sleeve body.

The utility model provides a femoral head operation area protective sleeve for a dislocation approach of hip joint surgery, which is provided with a circular ring, an annular bag and an elastic rope, wherein the circular ring is made of elastic transparent film materials, the periphery of the circular ring is upwards encircled to form a sleeve body, an upper opening of the sleeve body is larger than a lower opening and covers an operation surface after the circular ring is unfolded, a bottom surface is arranged at the lower opening of the sleeve body, a preformed hole for a femoral head to pass through is arranged on the bottom surface, the periphery of the lower end of the sleeve body is provided with the annular bag with the inner part communicated, and the elastic rope penetrates into the annular bag to form an annular shape and extends out of the two ends.

The beneficial technical effects of the utility model are as follows: the elastic transparent film material of the protective sleeve can be PU operation film, iodophor operation film or PE operation film. The sleeve body can be designed into three types of large, medium and small according to the body shape of a patient, because the diameter of the preformed hole is smaller than that of the femoral head, the preformed hole prepared by the transparent film material has certain elastic contraction force, the femoral head can pass through the preformed hole with the elastic contraction force, and after passing through the preformed hole, the preformed hole can be attached to the base part of the femoral head or the neck of the femur by virtue of the elastic contraction force of the preformed hole, so that a first layer of sealing protection is formed; the elastic rope is tightly tied on the base part of the femoral neck below the preformed hole by tightening the adjusting buckle, so that a second layer of sealing protection is formed, and soft tissue fragments or bone fragments of a patient can be effectively prevented from entering the hip bone socket in the operation process. The upper sleeve body disclosed by the utility model can be used for carrying out good isolation protection on soft tissue incisions which are not required by surgical operation after being abducted, is also beneficial to reducing the risk of infection in an operation area, and has the characteristics of simple structure, convenience in use, capability of ensuring the surgical effect and improving the medical care operation efficiency.
