Lin Chen has studied a lot of hand trauma during this time, and the commonly used tendon anastomosis of this ruptured tendon is mainly the double cross method, figure-8 suture, Kessler suture, etc., like this fresh ruptured tendon, as long as the end of the anastomosis is good, but the problem is that the proximal end of the ruptured flexor tendon is not easy to find.

He thought that when he was in the provincial medical center, didn't there be a teacher who used a needle to temporarily fix the tendon + expand the method?

Thinking of this, Lin Chen immediately continued to Lu Xiaohan: "Give me two No. 5 needles"

At this time, everyone looked at Lin Chen, curiously watching what he was doing with the No. 5 needle?

Lin Chen picked up the No. 5 needle, first pulled out a part of the tendon distal to the thumb and fixed it in the soft tissue injury, the distal tendon has been retracted, if the patient has little activity, it may be found and pulled out smoothly in the proximal sheath.

Lin Chen first stuffed the small bend into the tunnel of the tendon sheath, but he didn't find the broken tendon.

He tried again to find the proximal ruptured tendon in the tendon sheath with a small bend, but to no avail. Lin Chen knew that repeatedly looking for proximal ruptured tendons under the condition of blind vision in the tendon sheath would damage the surrounding nerves and blood vessels if he was not careful.

Since the ruptured tendon could not be found in the tunnel of the tendon sheath, Lin Chen immediately said to Lu Xiaohan: "Give me the scalpel"

"I really didn't expect this flexor tendon to retract so much"

"If only the proximal end of this flexor tendon rupture was in the tendon sheath"

"Ten fingers are connected to the heart, and when the patient's muscles are contracted, they must be connected to the proximal flexor tendons, which are rarely found on the incision," said the director of the plastic surgery department.

Lin Chen picked up the scalpel with a pen in his right hand and slowly cut along the medial radial side of the incision, and the knife directly cut from the proximal end of the thumb in a semi-oval shape to a distance of only 1cm from the wrist joint.

At this time, everyone didn't understand why Lin Chen had expanded the incision of the operation so widely, even if the proximal end of the flexor tendon could not be found, wasn't it looking for it while expanding? Why was it so big with a single cut? Isn't this aggravating the patient's injury?

Lin Chen picked up the pinch again and twisted the skin at the proximal end of the thumb and pulled it up, using the small bend to separate the soft tissue at the thumb to the palm again, and finally found the severed flexor tendon in the palm, and Lin Chen immediately used a No. 5 needle to temporarily fix it on the soft tissue next to it.

After finding the ruptured tendon, everyone's hearts were relieved, this Lin Chen's courage was really big enough, and he could think of this expansion and later looking for this ruptured tendon.

"The function of this No. 5 needle is to temporarily fix the tendon to avoid further retraction of the tendon, Lin Chen still did a very good job in this regard, but we didn't understand that the incision was so long," said Zhang Hong, director of surgery.

"It's just that this ruptured flexor tendon anastomosis, we haven't seen it, if the anastomosis is not good, the operation will be done in vain"

"This tendon anastomosis, it's not easy to do"

The doctors in the audience whispered, just because Lin Chen boldly extended the incision to find the tendon, many doctors didn't dare and didn't know how to look for it.

Lin Chen had already fully devoted his energy to the operation, and he didn't pay any attention to the comments of the visiting doctors in the audience.

He continued to Lu Xiaohan: "Give me the tendon anastomosis, anastomosis tendon."

At this time, I saw Lin Chen pick up the tendon anastomosis with the needle and thread it through the proximal end of the tendon first, then threaded the needle on the same side of the tendon needle, pulled out part of the tendon line, and then inserted the needle again from 1mm above the needle just now, directly crossed the opposite side, and pulled out part of the tendon line.

The needle is inserted again 1 mm below the contralateral exit needle to penetrate the broken end, and the whole process is like a "U" shape. Lin Chen's technique is like a girl embroidered in Jiangnan, and she is very skillful.

Similarly, Lin Chen once again took the needle and pierced it into the white tendon on the distal side, and the process was like a reverse "U" shape. Lin Chen removed the No. 5 needle at this time, pulled up the tendon sutures, and the severed tendon slowly brought it closer together, and with the completion of the knot, a white tendon had been intact and completed.

"Lin Chen, what was your method of anastomosis tendon just now?"

"Kessler's most basic method," Lin Chen replied.

At this time, Lin Chen's tendon suture was sutured with a circle of intermittent sutures, which was the modified Kessler.

After anastomosis of the tendon, Lin Chen did not stop the rhythm, he picked up the scalpel again and cut a reverse oval line from the proximal end of his thumb.

After cutting through the line, an oval skin appeared in front of everyone.

"Lin Chen, what is this going to do"?

"Is this oval-shaped skin used to mend a defect in the thumb?"

"What kind of surgery is this"?

At this time, the director of the plastic surgery department said: "This is Lin Chen's mastery, an incision is dual-purpose, and the skin on the radial side of the thumb is used to repair the thumb defect retrograde."

Dr. Liu Fan, who has been rotated from the Department of Plastic Surgery, has never seen such a wound repairing a defect, and after being pointed out by the director of the Department of Plastic Surgery, he seems to understand a little more.

"Xiao Liu, fortunately, you came to the surgical rotation, Lin Chen's retrograde reversal with pedicle flap, you have to take a closer look, we don't necessarily have such an operation," said the director of the plastic surgery department to Dr. Liu Fan.

After Lin Chen cut the skin, he slowly searched for the dorsal radial artery, and then transferred the flap and blood vessels to the abdomen of the thumb to repair the defect of the soft tissue of the thumb.

Although the defects of the index finger and middle finger are not as severe as those of the thumb, they cannot be sutured.

At this time, all the doctors stared at Lin Chen again, only to see that after Lin Chen took the scalpel again, he quickly made a V-Y-shaped incision at the tip of the distal finger of the index finger, separated the surrounding tissues, and pushed the incised skin to the distal end, and the defective tissue was already intact and covered.

Just when everyone hadn't come to their senses yet, Lin Chen installed the same method again to repair the defect in his middle finger.

The visiting doctors had no time to learn, the operation was over at this time, and the entire operation only took an hour, this complicated operation was already too fast in the eyes of all the doctors in Jiangxia, but Lin Chen knew that if it was those doctors in the provincial medical center, there would be faster and better.

"Lin Chen, what was the surgical method for your index finger and middle finger just now," said the director of the emergency department.

Lin Chen said with a smile: "V-Y propulsion technique, this method is quite easy to use to deal with such a small defect."

Operation No. 1 had just ended, and Lin Chen had already come to operating room No. 2.

Due to emergency surgery, Su Xiaoping's operation was postponed.

After the handwashing, disinfection, and towel laying are completed, due to the small size and fast time of the flap stump surgery, such operations are basically done under local anesthesia.

Lin Chen injected the diluted local anesthetic into the junction between the hand and the abdomen, and cut off the pedicle soon after the anesthesia took effect, and quickly sutured the wound, and the whole operation took less than 20 minutes.

Lin Chen's surgical ability improved very quickly during this period of forbidden surgical privileges, and Director Zhang Hong kept nodding.

Out of the operating room, Chen Li was already waiting for Lin Chen at the door, and the dimples on her face looked really good

She said to Lin Chen: "Lin Chen, congratulations, you have taught us another medical lesson."

Lin Chen smiled, but he knew that he would leave Jiangxia sooner or later, would Chen Li go?。。。。。。
