Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an adjustable wire loop for tendon protection and a titanium plate with a loop provided with the adjustable wire loop. Background Art

[0002] The current adjustable loop steel plate has the problem of too thin loops, which can easily cause the loops to directly contact and damage the transplanted tendon during the implantation process. In particular, when the bone tunnel is too tight, the graft is more likely to be cut and broken.

[0003] In order to reduce the risk of graft damage, the diameter of the bone tunnel can usually be enlarged or reduced. However, both of the above methods are not conducive to tendon-bone healing and may also lead to the expansion of the bone tunnel. Utility Model Content

[0024] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0025] like Figure 1 As shown, an adjustable line loop for tendon protection comprises a line sleeve 11 and a line loop;

[0026] The wire sleeve 11 is U-shaped and has a left opening and a right opening at the end;

[0027] A wire loop is connected to the left opening, and the wire loop passes through the right opening into the wire sleeve 11, and then passes through the left opening and extends to form a wire tail 13;

[0028] A wire loop is connected to the right opening, and the wire loop passes through the left opening into the wire sleeve 11, and then passes through the right opening and extends to form a wire tail 13;

[0029] The wire loop and the wire sleeve 11 are enclosed to form a coil 12;

[0030] The wire tail 13 of the wire loop is received in or extended out of the wire sleeve 11 to achieve the length adjustment of the coil 12 .

[0031] The adjustable length of the coil 12 is designed to be 10mm-100mm. The utility model uses the principle of wire encapsulation to make a wire encapsulation structure with adjustable wire loop length, and also increases the diameter of the coil, increases the contact area with the graft, and reduces the pressure; when tightening the two tail wires at the same time, the wire loop length is adjusted. During the adjustment, the wire encapsulation structure is stationary relative to the graft and will not rub on the graft, reducing the cutting and damage to the graft. It can effectively reduce the friction between the graft and the wire loop, reduce the risk of the graft being cut and broken, and can select bone tunnels of the same size according to the diameter of the graft, which is conducive to tendon-bone healing and reduces the probability of bone tunnel expansion.

[0032] A titanium plate with loops and an adjustable loop, comprising a titanium plate with loops 2 and the above-mentioned adjustable loop for tendon protection;

[0033] The middle part of the titanium plate with loop 2 is provided with a first titanium plate hole 23 and a second titanium plate hole 24 from left to right; a turning hole 21 is provided on the titanium plate with loop 2 to the left of the first titanium plate hole 23, and a traction hole 22 is provided on the titanium plate with loop 2 to the right of the second titanium plate hole 24;

[0034] The wire loop connected to the left opening of the wire sleeve 11 passes through the first titanium plate hole 23 and the second titanium plate hole 24 in sequence, and then passes into the wire sleeve 11 through the right opening;

[0035] The wire loop connected to the right opening of the wire sleeve 11 passes through the second titanium plate hole 24 and the first titanium plate hole 23 in sequence, and then enters the wire sleeve 11 through the left opening.

[0036] In addition, the loop hole 21 is connected to a loop rope, and the traction hole 22 is connected to a traction rope.

[0037] The inner edges of the first titanium plate hole 23 and the second titanium plate hole 24 are in a smooth transition.

[0038] The left and right ends of the titanium plate with loop 2 are semicircular structures 25 .

[0039] The edge of the titanium plate with loop 2 is a smooth transition structure. The structure of the titanium plate with loop is relatively conventional, so it will not be described in detail.

[0040] When in use, the graft is connected to the adjustable wire loop, and then the adjustable wire loop is passed through the titanium plate with loop; then the loop wire is passed through the loop hole on the titanium plate with loop, and the traction wire is passed through the traction hole on the titanium plate with loop, and then other medical devices are used to bring the traction wire from the incision into the bone marrow canal, so that the traction wire can pull the titanium plate with loop from the incision into the bone marrow canal, and then the adjustable wire loop and the graft are introduced into the bone marrow canal.
