Description

Meniscus suturing device and using method thereof

Technical Field

The invention relates to the technical field of medical equipment, in particular to a meniscus suturing device and a using method thereof.

Background

When people in the motion process, because reasons such as some irregular actions or dynamics are too big, let the atress of knee joint department thighbone and shin bone unbalanced, lead to the thighbone to act on the power of meniscus to appear the deviation, arouse tearing of meniscus very easily, produce the crack. And the appearance of the meniscus suture main body can suture the torn part and the original meniscus on the operating table, thereby recovering the activity function of the knee joint.

When the posterior half meniscus is torn, the medical staff firstly puncture one side of the half meniscus crack by adopting the half meniscus sewing main body and then excite a first implant to be hung on the rear wall of the half meniscus; after the first implant is successfully attached, the meniscus suture body is taken out to puncture the other side of the meniscus crack again, the second implant is triggered, the second implant is attached to the rear wall of the meniscus in the same way, and finally the suture is tightened to tighten the two implants, so that the meniscus suture is completed.

Medical care personnel are needed to puncture the meniscus by artificially controlling the force in the operation process. Because the meniscus is a cartilage tissue, when medical staff puncture the meniscus, the medical staff often needs a large pushing force to penetrate the meniscus, the puncturing force is difficult to control, and the tissue nerve behind the meniscus is easy to puncture due to the action of inertia. And in current meniscus suture process, need arouse many times and pierce through the meniscus to implant the implant many times, and realize sewing up through the implant, medical staff need study through a period of time just can judge the condition that is in which kind of excitation state when using current meniscus suture main part. If misjudged, secondary damage to the meniscus may result.

Chinese utility model patent with application number CN201520214262.8 discloses a meniscus suture main part, holds the handle and directly punctures the meniscus, arouses an implant to be affiliated to on the meniscus outer wall for the first time, arouses the second implant to be affiliated to on the meniscus outer wall for the second time, tightens up the suture at last and realizes tearing the meniscus and sew up. This patent is all through the arm protraction and stop to control the dynamics of penetrating when puncturing the meniscus and implanting the implant, because arm swing amplitude is great, the dynamics is difficult to control, if the dynamics undersize, be difficult to pass the meniscus, if the dynamics is too big, then puncture behind the meniscus tissue nerve easily. And medical personnel need to learn the main instrument for a period of time before performing the meniscal suture operation to judge that the main instrument is in the second activated state.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: when present meniscus sews up impaling and implanting the implant when its uses, the dynamics is difficult to control, if the dynamics undersize, is difficult to puncture harder meniscus, if the dynamics is too big, then stab the tissue nerve very easily after piercing half meniscus, and two needle bodies of single impaling mode control are unfavorable for medical staff's judgement meniscus suturing device's operating condition, and the operation degree of difficulty is high, lead to easily impaling misoperation.
