Technical Field
The utility model relates to the technical field of medical equipment, in particular to a meniscus suture device and a using method thereof.
Background
When people move, because of irregular actions or overlarge force and the like, the stress of the femur and the tibia at the knee joint is unbalanced, so that the force of the femur acting on the meniscus is deviated, the meniscus is easily torn, and cracks are generated. The presence of the meniscus suture body enables the torn portion to be sutured with the original meniscus on the operating table, thereby restoring knee joint mobility.
When the rear corner of the meniscus is torn, medical staff adopts a meniscus suture main body to pierce one side of the meniscus fracture in advance and then excite a first implant to be hung on the rear wall of the meniscus; after the first implant is successfully hung, the meniscus suture main body is taken out to puncture the other side of the meniscus crack again, the second implant is excited, the second implant is also hung on the rear wall of the meniscus, and finally the suture is pulled to tighten the two implants, so that the suture of the meniscus is completed.
During the operation, medical staff is required to puncture the meniscus by manual control force. Because the meniscus is a cartilage tissue, when medical staff punctures the meniscus, the medical staff often needs a large pushing force to pass through the meniscus, the puncturing force is difficult to control, and tissue nerves after the meniscus are punctured easily due to the action of inertia. In addition, in the existing meniscus suture process, the meniscus is required to be penetrated through by multiple excitations so as to implant an implant for multiple times and realize suture through the implant, and medical staff needs to learn for a period of time to judge which excited state is in when the existing meniscus suture main body is used. If misjudgment is made, secondary damage to the meniscus may result.
The Chinese patent application No. CN201520214262.8 discloses a meniscus suture main body, a hand-held handle directly pierces meniscus, one implant is excited to hang on the outer wall of the meniscus for the first time, the second implant is excited to hang on the outer wall of the meniscus for the second time, and finally suture lines are tightened to tear meniscus suture. The patent is all stretched and is stopped to control the dynamics of penetrating through the arm when puncture meniscus and implant, because the arm swing range is great, the dynamics is difficult to control, if the dynamics is too little, is difficult to pass the meniscus, if the dynamics is too big, then the tissue nerve behind the meniscus is punctured easily. And a period of learning of the subject instrument is required before the medical staff performs the meniscal suturing operation to determine what number of activated states the subject instrument is in.
