Description
Technical Field
The application relates to the technical field of automatic achilles tendon locking and sewing devices, in particular to an automatic achilles tendon locking and sewing device.
Background
The incidence rate of achilles tendon rupture is about 3/mill, and the incidence rate is improved year by year along with popularization of the sports of the whole people. Open surgery treatment can significantly reduce the rate of re-fracture and increase plantarflexion forces. Currently, there are Kessler, bunnell, krackow and other techniques for suturing achilles tendon open. Biomechanical studies demonstrated that the strength of the Krackow suture was 1.73 times that of Kessler and 1.58 times that of Bunnel. Labib in 2009 proposed an improved Krackow with the tail at each end fixed to the opposite Krackow cross arm. This stitching method allows four strands of suture to pass through the broken ends, which is about 2 times stronger than conventional Krackow, known as "Giftbox" stitching, which has the disadvantage that the knots are cut by cross arms on opposite sides of Krackow, resulting in easy failure. Latch Blocking Modified Kraow (LBMK) was a proposed suturing method in 2018, with two side kraow tails threaded through the latches of the opposite side kraow, and with the last latch being needled out, so that the knots can be blocked by the latches and tendon tissue of the opposite side kraow, which forms an interlocking structure of the two kraow. According to biomechanical model tests simulating early rehabilitation, the suture strength of LBMK is as high as 769N and is far higher than Giftbox (648N), so that LBMK is the suture method with the highest strength of the current open repair achilles tendon, and the method can be operated by minimally invasive operation. Surgical incisions in the achilles tendon site are in the relative ischemic area, with a wound complication rate of up to 10% after open surgery.
For the last 10 years, with the progress of instruments and treatment concepts, minimally invasive surgical modes commonly used at present gradually appear: achillon, percutaneous Achilles tendon repair System (PARS), speedBridgem, channel assisted minimally invasive suture System (CAMIR), minimally invasive latch blocking modified Krackow (MI-LBMK), and the like. However, none of these methods are applicable to early functional rehabilitation. The MI-LBMK technology proposed in 2018 is that the LBMK suturing method with the strongest current suturing technology is applied to minimally invasive, the suture is completed through two small incisions at the far end and the near end, needle access points of Krackow are all not at the broken end, after the Krack ow is sutured at the far end and the near end, the tail of the thread can be led to the opposite side through threading in tendon Zhou Qiao, then the opposite side is threaded through a lock catch, and then the suture is tensioned and knotted, and the suture is wound around the broken end to form three-dimensional scattered peritendinous fixation. This suturing method has strong biomechanical advantages in biomechanical testing. The maximum failure loads for the 6 strand suture LBMK group, giftbox group, kessler group and PARS group were 769N, 648N, 510N and 379N, respectively, at a speed stretch of 25 mm/s. Therefore, both LBMK and MI-LBMK are interlocking technology of a Krackow structure, have high suture strength and few knots, and are the suture method with the highest repair strength of the achilles tendon at present. However, since the Krackow suture structure is relatively complex, a plurality of lock braiding is needed, and the operation requires that the Krackow suture is performed in two incisions of 2-3cm, and has high requirements on the suture technology. Since the Krackow technique was designed to open the achilles tendon, there is currently no stapler capable of performing a Krackow minimally invasive suture. Therefore, there is a need to design a hand-held suture device to perform krack-edge-locking suture, which can reduce the wound more, reduce the operation difficulty, and facilitate the popularization of MI-LBMK technology.
