Embodiment 1

[0031] Embodiment 1: a kind of preparation method of plasticized specimen of necrosis of femoral head replacement, comprises the following steps:

[0032] S1: Human specimen processing: In S1, the specimen was perfused with formalin with a volume fraction of 15% to 20%, and the formalin was infiltrated into various parts of the specimen through large blood vessels, and finally the treated specimen was placed in Soak in formalin solution with a volume fraction of 8% to 12% for 3 to 4 months. Afterwards, the femoral artery and femoral vein were perfused with silica gel so that the blood vessels could be displayed more clearly;

[0033] S2: Material collection: Sagittal incision of the abdominal wall at the level of the navel, ligation and cutting at the sigmoid colon, pulling up the viscera, cutting at the level of the intervertebral disc of the twelfth thoracic vertebra, and keeping the intact pelvic lower limbs;

[0034] S3: Anatomy:

[0035] a) The right skin and superficia...

[0047] Embodiment 2: a kind of preparation method of plasticized specimen of necrosis of femoral head replacement, comprises the following steps:

[0048] S1: Human specimen processing: In S1, the specimen was perfused with formalin with a volume fraction of 15% to 20%, and the formalin was infiltrated into various parts of the specimen through large blood vessels, and finally the treated specimen was placed in Soak in formalin solution with a volume fraction of 8% to 12% for 3 to 4 months; then infuse silica gel at the femoral artery and femoral vein, so that the blood vessels can be displayed more clearly;

[0049] S2: Material collection: Sagittal incision of the abdominal wall at the level of the navel, ligation and cutting at the sigmoid colon, pulling up the viscera, cutting at the level of the intervertebral disc of the twelfth thoracic vertebra, and keeping the intact pelvic lower limbs;

[0050] S3: Anatomy:

[0051] a) The right skin and superficial fascia of the sp...

Abstract

The invention relates to a femoral head necrosis replacement plastified specimen manufacturing method. The method comprises the following steps: performing preservative treatment on a human body specimen; then taking materials and dissecting to completely retain the femoral head; then carrying out bleaching, dehydrating, degreasing and the like on the dissected specimen; removing the femoral head on the left side of the specimen, and installing a prosthesis femoral head; opening the upper end of the femur sagittally, so that the position of the prosthesis femur head in the marrow cavity can be clearly displayed; then, mounting a strong magnet on the inner surface of the opened muscular tissue, and finally curing and trimming the specimen to obtain the plasticized specimen of the femoral head necrosis replacement. According to the invention, teaching and learning about the femoral head necrosis replacement are facilitated, and the specimen is non-toxic, odorless and convenient to store for a long time.

Description

technical field [0001] The invention relates to the technical field of making plasticized specimens, in particular to a method for making plasticized specimens for femoral head necrosis replacement. Background technique [0002] Femoral head necrosis is a common hip joint disease. The blood supply to the femoral head is interrupted or damaged, resulting in the death and subsequent repair of bone cells and bone marrow components, which in turn leads to structural changes in the femoral head, collapse of the femoral head, and joint dysfunction. . This disease is very harmful. If the best treatment time is missed, lameness of the affected limb may occur, and even paralysis of the affected limb may occur in severe cases, which will seriously affect the life and work of the patient. For patients with femoral head necrosis in the early stage, drug therapy can relieve symptoms, prevent further deterioration of the disease, and make it enter a benign reversal recovery. If the pati...
