What is the operation step of thigh amputation?

summary

To do amputation, we must grasp the operation steps of thigh amputation, which is related to whether the operation can be carried out smoothly. Next, we will introduce the operation steps of thigh amputation in detail to see how to ensure the smooth operation and actively ensure the safety of the operation. Amputation and prosthesis must be suitable for the walking and weight-bearing function of amputated limb. Now the lower limb amputation accounts for about 85% of the total amputation, so it is also of great significance in statistics. The technical innovation and postoperative treatment of amputation, especially the pressure dressing after operation, the development of new artificial replacement technology, including computer-aided design and manufacturing of prosthesis sleeve, have greatly changed the surgical approach and rehabilitation.

What is the operation step of thigh amputation?

1. Supine position 2. The incision scar of the amputation on the knee is the same as that of the leg amputation, which should be behind the stump. The ideal truncation plane is 25cm below the top of the rotor. The flap design should be long in the front and short in the back (2 ∶ 1), and the intersection of flap incision on the side should exceed the cut-off plane. After incision, the flap was separated under the fascia and turned up; Or the rectus femoris flap with a thickness of 1cm was separated and cut off at the same length as the anterior flap.

The diseased limb was amputated at the amputation plane, and the great saphenous vein was ligated and cut off. The femoral artery, vein and saphenous nerve were separated under sartorius muscle or adductor muscle tube, and cut and treated according to routine. The muscle was cut to the femur 2-3cm below the plane of amputation. The periosteum was cut at the plane of amputation. The femur was sawed and the diseased limb was severed.

The deep femoral artery and vein were separated from the femur, adductor magnus and biceps femoris, and double ligated. Then, the sciatic nerve was separated between semitendinosus, Semimembranous and biceps femoris, and was gently pulled out. Procaine was injected into the proximal part of the sciatic nerve. After ligation of the nutrient vessels, the sciatic nerve was cut off and allowed to retract naturally.

matters needing attention

The incision was sutured and the shoulder joint was severed. One piece of treatment towel and tourniquet were handed over. One piece of operation film and dry gauze were handed over to assist in sticking film. Two pieces of dry gauze were laid on both sides of the incision to wipe blood; There are teeth forceps, No.20 knife to cut skin, electric knife to cut subcutaneous tissue, straight forceps to help clamp; The nerve was protected by wet gauze. The blood vessels were separated and clamped with No. 4 silk thread. The nerve sheath was sealed with 20ml procaine syringe. The nerve was cut off with No. 11 knife. The nerve was cut off with No. 20 knife. The periosteum was stripped with ion. The bone was cut off with electric saw and the wound edge was repaired with bone file, Bone wax or absorbable gelatin sponge hemostasis, bending mosquito forceps, No.1 silk thread or electrocoagulation hemostasis combined with this shoulder joint amputation.
