Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical devices, especially relates to a full suture meniscus suture fixing assembly. BACKGROUND

[0002] Meniscus is the bone tissue of medial and lateral semilunar shape on the tibial articular surface, normal meniscus has the effect of increasing tibial condyle concave and cushioning femoral medial and lateral condyles, and increasing the stability of joint and buffering shock. Daily life and exercise can often lead to meniscus injury, resulting in meniscus shape and structure damage or abnormality, thus causing meniscus function loss, abnormal joint stress distribution, joint instability and the like. Meniscus suture is a common surgical method for treating meniscus injury at present, two fixers connected by suture are implanted into different positions of meniscus, and then the suture is tightened to suture the damage and tear.

[0003] As shown in Figure 7 The existing full suture meniscus suture fixing device is composed of a first fixing piece, a second fixing piece and a suture, the suture sequentially passes through the first fixing piece, the second fixing piece and then the first fixing piece again to form a double locking structure. One end of the suture is fixed on the first fixing piece by a knot. When implanted into the human body, the position is easy to cause the thread end to come out due to the tension of the suture, resulting in suture failure and suture shedding, and the safety and reliability are poor. CONTENT OF THE UTILITY MODEL

[0004] Therefore, in order to solve the above technical problems, the utility model provides a full suture meniscus suture fixing assembly which is safe and reliable, can avoid suture shedding and has high firmness and stability.

[0005] In order to achieve the above purpose, the technical scheme of the utility model is as follows:

[0006] A full suture meniscus suture fixing assembly, comprising:

[0007] A first fixing piece, two thread holes one are arranged on the first fixing piece at intervals, and a containing groove is formed on one side of the two thread holes one;

[0008] A second fixing piece, two thread holes two are arranged on the second fixing piece at intervals;

[0009] A suture, one end of the suture is fixed with a clamping piece; the suture passes through one of the thread holes one, so that the clamping piece is clamped at the thread inlet of one of the thread holes one and contained in the containing groove; the other end of the suture sequentially passes through the other thread hole one and the two thread holes two to connect the first fixing piece and the second fixing piece together.

[0010] The fixing piece one is provided with a containing groove on the upper end, and the clamping piece is clamped in the containing groove on the upper end of the threading hole one, which can fix the suture and prevent it from falling off, thereby improving the stability and safety compared with a simple knot.

[0011] Further, the front end of the fixing piece one and the fixing piece two are both in a tapered structure, and the rear end is in a dovetail groove structure.

[0012] The tapered structure facilitates smooth implantation into the body through a meniscus suture device, and the dovetail groove structure facilitates docking with a push rod of the meniscus suture device.

[0013] Further, the taper angles of the tapered structures of the fixing piece one and the fixing piece two and the two taper angles of the dovetail groove structure are all arc-shaped angles, thereby avoiding scratching.

[0014] Further, the clamping piece is in a block structure, is provided with a through hole with a diameter smaller than the threading hole one and greater than the diameter of the suture, one end of the suture passes through the through hole and is knotted, the diameter of the knot is greater than the diameter of the through hole, the other end of the suture passes through another threading hole one and two threading holes two in sequence, and then passes through the suture below the knot again, and then passes through the through hole and two threading holes one in sequence.

[0015] The clamping piece and the suture are not integrally connected, but the suture is arranged through the through hole with a smaller diameter of the clamping piece, and then a knot is knotted, which can avoid the knot from falling off compared with directly passing through the threading hole one, and the suture is further arranged below the knot after being wound back, thereby further improving the firmness, providing double protection together with the fixing piece, and not affecting the tensioning of the subsequent suture.

[0016] Further, the clamping piece is in a block structure, one end of the suture is in an integral structure with the clamping piece, a circumferential groove is arranged on the side surface of the clamping piece, the other end of the suture passes through two threading holes two, is arranged in the groove at least once, and then is arranged out of the groove.

[0017] The clamping piece and the suture are in an integral structure, the suture is arranged in the groove on the clamping piece after being wound back, thereby improving the firmness, providing double protection together with the fixing piece, and not affecting the tensioning of the subsequent suture.

[0018] Further, a plurality of guide grooves are arranged on the clamping piece in a circumferential direction at equal intervals, the guide grooves are arc-shaped grooves, one end of the guide groove is in communication with the groove, and the other end extends upward to be flush with the side surface of the clamping piece, and the suture enters the groove from the guide groove and extends out of the groove.

[0019] The guide groove is used for providing a path for the suture to enter or exit the groove, and makes the subsequent suture tightening operation more smooth.

[0020] Compared with the prior art, the full-suture meniscus suture fixing assembly has the following advantages:

[0021] The full-suture meniscus suture fixing assembly has the following advantages: the fixing member one is arranged on one end of the suture, the accommodating groove is arranged on the fixing member one, the clamping member is clamped in the accommodating groove on the upper end of the threading hole one, and the clamping member can fix the suture and prevent the suture from falling off.
