Problems solved by technology

At present, a titanium plate with a fixed coil at the femoral end is usually used to fix the grafted tendon at the femoral end, and the tibial end is fixed with interface screws, and the fixation method is relatively simple.
The existing titanium plate structure cannot complete the fixation of the tibial end, it is easy to move back and forth, and the installation is unstable
The coil length of the fixed plate with loops cannot be adjusted, and it needs to be measured and calculated for different operations, which increases the operation time

Embodiment 1

[0025] Embodiment 1 of the present invention: as Figure 1 ~ Figure 3 As shown, a new type of belt loop fixing plate includes a belt loop plate body 1, a first threading hole 2 and a second threading hole 3 are opened through the belt loop plate body 1, the first threading hole 2 and the second threading hole 3 There is a connecting line inside. Specifically, the connecting line is adjustable, specifically, it may be a medical suture. The side of the first threading hole 2 away from the second threading hole 3 is provided with a first through portion 5 , and the side of the second threading hole 3 away from the first threading hole 2 is provided with a second through portion 6 . The connecting wires can enter the first threading hole 2 from the outside through the first through portion 5 , and the connecting wires can also enter the second threading hole 3 from the outside through the second through portion 6 . The back side of the plate body 1 with loops is also provided wi...

Embodiment 2

[0027] Embodiment 2: as Figure 1 ~ Figure 3 As shown, a new type of belt loop fixing plate includes a belt loop plate body 1, a first threading hole 2 and a second threading hole 3 are opened through the belt loop plate body 1, the first threading hole 2 and the second threading hole 3 There is a connecting line inside. The side of the first threading hole 2 away from the second threading hole 3 is provided with a first through portion 5 , and the side of the second threading hole 3 away from the first threading hole 2 is provided with a second through portion 6 . The connecting wires can enter the first threading hole 2 from the outside through the first through portion 5 , and the connecting wires can also enter the second threading hole 3 from the outside through the second through portion 6 . The back side of the plate body 1 with tabs is also provided with a protrusion 7, which is placed in the bone after the operation to prevent the main body 1 of the plate with tabs f...

Embodiment 3

[0028] Embodiment 3: as Figure 1 ~ Figure 3 Shown, a kind of using method of novel belt loop fixed plate adopts above-mentioned novel belt loop fixed plate, comprises the following steps:

[0029] During cruciate ligament reconstruction surgery, the femoral end (or tibial end) is fixed with the graft first, and the tibial end (or femoral end) is braided with an adjustable connecting thread (specifically, it can be a medical suture thread). At this time, the adjustable connecting wire is pulled out of the bone canal, and the adjustable connecting wire is divided into the first threading hole 2 and the second threading hole 3 of the titanium fixing plate with loops (the adjustable connecting wire and the titanium fixing plate with loops are separated). During assembly, the surface where the protruding part 7 is located is close to the bone opening), specifically, the adjustable connecting wire enters the first threading hole 2 from the outside through the first through part 5, ...

Abstract

The invention discloses a novel belt carrier fixing plate, and belongs to the technical field of cruciate ligament reconstruction surgery. The novel belt carrier fixing plate comprises a belt carrierplate body, and a first threading hole and a second threading hole are formed in the belt carrier plate body. The side, away from the second threading hole, of the first threading hole is provided with a first penetrating part, and the side, away from the first threading hole, of the second threading hole is provided with a second penetrating part. The back surface of the belt carrier plate body is also provided with a protrusion part. By means of the novel belt carrier fixing plate, a variety of options are provided for tool type selection in the cruciate ligament reconstruction surgery, notonly can belt carrier fixing plates be selected and used at the two ends of a transplant, but also the belt carrier fixing plate can be selected and used at one end of the transplant, and an interfacescrew is selected and used at the other end of the transplant; through the arrangement of the protrusion part, the belt carrier fixing plate can be prevented from moving on the cortical bone back andforth, the installation stability is improved, and postoperative recovery of a patient is facilitated; an adjustable connecting line can be installed, type selection does not need to be calculated during the surgery, and the surgical time is shortened.

Description

technical field [0001] The invention relates to a novel belt loop fixing plate, which belongs to the technical field of cruciate ligament reconstruction surgery. Background technique [0002] With the development of orthopedic sports medicine, anterior and posterior cruciate ligament reconstruction surgery has received more and more attention and application. Cruciate ligament reconstruction surgery is the rupture of the anterior cruciate ligament or posterior cruciate ligament due to injury, and the reconstruction of the anterior cruciate ligament or posterior cruciate ligament with autograft tendon or allograft tendon or artificial graft, during which the graft passes through the tibial tunnel and femoral tunnel Fixed connections on both sides. At present, a titanium plate with a fixed coil at the femoral end is usually used to fix the grafted tendon at the femoral end, and the tibial end is fixed with interface screws, and the fixation method is relatively simple. The e...
