Technical Field
The invention relates to a fixing device and a surgical method using the same, belonging to the field of medical surgery.
Background
Ligament tibial insertion avulsion fracture (posterior cruciate ligament tibial insertion avulsion fracture is an example). The traditional operation mode is that the patient is in a prone position, and the popliteal fossa is cut to expose the fracture. And performing internal fixation of fracture. Generally, two left and right metal hollow nails are used for fixing. The internal fixation can be taken out after 12 months to 18 months after the operation.
The scheme is a traditional operation test, and the popliteal fossa has abundant nerve vessels and high incision risk. And the metal hollow nail is easier to fix under the condition that the cut fracture block is larger and complete. If the bone block is small and broken, the metal hollow screw is difficult to hold, and the operation effect is affected. The traditional operation needs to be done by incision, the incision is large, bleeding is much, the recovery time of the postoperative patient is long, and the postoperative patient needs to be taken out and internally fixed. The secondary incision operation of nail taking brings great loss to the patients and the family members thereof from the aspects of economy, body and mind.

In order to achieve the purpose, the technical scheme of the invention is as follows: a ligament tibia insertion avulsion fracture fixation device comprises a first fixation block, a second fixation block and a suture, wherein the first fixation block, the second fixation block and the suture are matched for use, a plurality of wings extend out of the peripheries of the first fixation block and the second fixation block, a recessed area is formed between every two wings, a clamping groove is arranged in the recessed area of the first fixation block, and holes are formed in the recessed area of the second fixation block; the suture line crosses through four opposite holes of the second fixing block to form two 8-shaped knots, two thread ends of the suture line finally penetrate out of the two opposite holes respectively, two arc-shaped rope rings are formed at the other end of the suture line, and the two arc-shaped rope rings are sleeved in two opposite clamping grooves of the first fixing block respectively.
Four symmetrical wing wings are uniformly distributed on the peripheries of the first fixed block and the second fixed block.
The back of each wing is provided with a fixing nail.
The opposing wing heads are skewed to the same clockwise or counterclockwise direction.
The width of the notch of the clamping groove is smaller than the diameter of the inside of the groove and larger than the diameter of the suture.
The hole pitch of the four holes of the first fixing block is equal to that of the four holes of the second fixing block.
The diameter of the fixed block circumscribed circle is 8-13 mm.
And a tightening belt is sleeved in the middle of each of the two 8-shaped knots.
After the structure is adopted, a tunnel is drilled from the inner side of the tibia to the fracture broken end by utilizing a special guider through an arthroscopic technology. Threading the suture and the second fixing block in advance to form two 8-shaped knots and two arc-shaped loops, arranging the first fixing block at the tunnel opening at the inner side of the tibia, arranging the second fixing block at the tunnel opening at the fracture end, and penetrating the two arc-shaped loops through the tunnel by using a threading tool. The two arc-shaped rope rings are clamped into the two opposite clamping grooves of the first fixing block, and the two far-end sutures are tightened to be fixed. Therefore, the invention can be matched with an arthroscope to realize minimally invasive fixation of the broken end of the fracture, the small incision shortens the postoperative rehabilitation time of the patient, and reduces the pain and the treatment cost of the patient
An operation method matched with the ligament tibial insertion avulsion fracture fixing device comprises the following steps of S1: through an arthroscopic technology, the entrance of the posterior medial opening of the knee joint is assisted, and tissues near a fracture block are cleaned to expose the fracture broken end; s2: a tunnel is drilled from the inner side of the tibia by using a guider, and the tunnel penetrates through a bone block until the fracture end is reached; s3: taking a first fixed block and a second fixed block, wherein the first fixed block is arranged at a tunnel opening at the inner side of the tibia, and the second fixed block is arranged at a tunnel opening at the fracture end; s4: the suture is crossed through the four opposite holes of the second fixing block to form two 8-shaped knots, two end heads of the suture finally penetrate through the two opposite holes respectively, and two arc-shaped rope loops are formed at the other end of the suture; s5: two arc-shaped rope rings penetrate through the tunnel and are respectively sleeved in two clamping grooves opposite to the first fixing block; s6: and tightening the suture thread head, and tightly attaching the first fixing block and the second fixing block to the bone surface. When the first fixing block and the second fixing block are tightly attached to the bone surface by tightening the suture thread head, the fixing nail on the back of the wing is abutted against the bone surface.
By adopting the operation method, a large incision at the popliteal fossa can be avoided, and the operation risk is reduced. The incision is small, the wound is small, the postoperative rehabilitation time of the patient is shortened, the integral hospitalization time of the patient is shortened, and the cost of the patient is reduced.
