Problems solved by technology

The materials of ligament substitutes also mostly use autologous and allogeneic tendon due to the consideration of durability, but these surgical methods using autologous and allogeneic tendon may lead to injury, infection, rejection, and the existence of donor sources and potential ethical issues

Embodiment Construction

[0028] In the following description, many technical details are proposed in order to enable readers to better understand the application. However, those skilled in the art can understand that without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in each claim of the present application can be realized.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0030] A first embodiment of the present invention relates to a ligament reconstruction system. figure 1 It is a schematic diagram of the structure of the ligament reconstruction system. The ligament reconstruction system comprises: a first intraosseous hollow channel 1, a second intraosseous hollow channel 2, a ligament substitute 3, a first fix...

Abstract

Disclosed is a ligament reconstruction system involved in the field of medical devices, and when using this system to perform the initial ligament reconstruction, and if a revision surgery is needed, the ligament can be quickly replaced via an extra-articular small incision, without the use of arthroscopy. Because of the quick revision characteristic of this technology, there is no longer any need for ligament substitute materials to be in solid combination with bone channels, making the reliable use of artificial materials other than autologous / allogeneic tendons be possible. The system also reduces the difficulty and expense of revision surgery, shortens the hospital stay time and expands ligament reconstruction indications. The system comprises: a first in-bone hollow pipe (1), a second in-bone hollow pipe (2), a ligament substitute (3), a first fixing member (4) and a second fixing member (5); the first in-bone hollow pipe (1) and the second in-bone hollow pipe (2) are respectively implanted in and run through a proximal joint bone (6) and distal joint bone (7), and the ligament substitute (3) is built inside the first in-bone hollow pipe (1) and the second in-bone hollow pipe (2).

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a ligament reconstruction technique. Background technique [0002] Joint ligament injury is a common sports injury. Severe ligament injury requires ligament reconstruction to restore joint stability. [0003] For cruciate ligament injuries of the knee with a high incidence, such repair operations usually need to be performed under arthroscopy at present. Existing surgical methods need to establish bone channels on the femur and tibia, fix ligament substitutes such as autologous tendons, allogeneic tendons or artificial ligaments on the femur and tibia through the bone channels, and rely on the tension provided by the ligament substitutes to rebuild the stability of the joint . Although arthroscopic ligament reconstruction surgery has become increasingly mature, there are still 10%-15% failure rate and 10%-20% revision rate reported in the literature. [0004] The success of liga...
