epineurial perineurium suture

Peripheral nerve injury within 1.8 to 12 hours, the pollution is light, and the possibility of wound infection is estimated to be small after debridement. Femoral suture or capsular suture can be performed. 2. Old or partial peripheral nerve rupture injury, after removal of the injured part and neuroma, nerve defect <2.0cm, or when the limb is in the neutral position or slightly flexed joint (<20°) and the broken end is free, the two ends It can be used without tension, and it is suitable for suture or capsular suture. 3. After the peripheral nerve injury or lesion resection, the nerve defect is >2.0cm, or when the limb is in the neutral position or the slightly flexed joint and the broken end are free, the two broken ends are still unable to match, and it is suitable for inter-beam nerve bundle transplantation. Treatment of diseases: peripheral nerve injury of neuroma Indication Peripheral nerve injury within 1.8 to 12 hours, the pollution is light, and the possibility of wound infection is estimated to be small after debridement. Femoral suture or capsular suture can be performed. 2. Old or partial peripheral nerve rupture injury, after removal of the injured part and neuroma, nerve defect <2.0cm, or when the limb is in the neutral position or slightly flexed joint (<20°) and the broken end is free, the two ends It can be used without tension, and it is suitable for suture or capsular suture. 3. After the peripheral nerve injury or lesion resection, the nerve defect is >2.0cm, or when the limb is in the neutral position or the slightly flexed joint and the broken end are free, the two broken ends are still unable to match, and it is suitable for inter-beam nerve bundle transplantation. Preoperative preparation Surgical design of the inter-beam nerve bundle transplantation, preoperative preparation of the skin of the donor area. The cutaneous nerve that can be used for transplantation has the sural nerve (a length of 25 to 40 cm for transplantation), a superficial branch of the radial nerve (for 20 to 25 cm), the medial cutaneous nerve of the upper arm, and the medial cutaneous nerve of the forearm (available for 20 to 28 cm). . The saphenous nerve, the lateral femoral cutaneous nerve, the posterior cutaneous nerve, and the intercostal nerve. The most commonly used graft nerve is the sural nerve, which is easy to expose, has few branches, and the numb area left after cutting is small, and is not in the weight-bearing area, followed by the superficial peroneal nerve. Surgical procedure 1. Exposing and dissociating nerve endings, removing neuroma or damaged nerve tissue, stopping bleeding and aligning nerve bundles or bundles, and suturing with neurobumin, but not abducing the epicardium. 2. Stitching 7-09-0 without damage needles, for 3 fixed point sutures, that is, first two sutures with two fixed points separated by 120°. After knotting, the nerve bundles are sutured from deep and shallow between two fixed points. Then suture the outer membrane 2 to 3 needles between the two fixed-point traction lines, and adjust the two fixed-point traction lines, and turn the nerve fracture ends 180°. Because they are separated by 120° two fixed points, after the nerve is reversed, the section has 240°. Sewing, so you can clearly see the majority of the nerve bundles. For those who have bad fit, you can use the tip of the needle to gently move and re-align. The nerve bundle membrane is then sutured by deep and shallow, and the epicardium is finally sutured. Postoperative diet The diet after surgery should be reasonably matched, and reasonable dietary intake is the key to promoting rapid recovery after surgery. Modern clinical studies have confirmed that long-term consumption of foods containing vitamins is also important for reducing wound infections and promoting wound healing after surgery.
