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

The invention relates to the field of medical instruments and discloses a ligament reestablishing system. After a ligament is reestablished for the first time by using the ligament reestablishing system, the ligament can be quickly replaced through a small incision outside a joint without using an arthroscope if a revision surgery needs to be carried out on the ligament. Because the technology has the character of quick revision, a ligament substitute material is not needed to be firmly combined with a bone channel any longer, so the ligament reestablishing system provides possibilities for reliable use of artificial materials except autologous/ allogenic tendons. Moreover, the difficulty and cost of the revision surgery are reduced, the hospital time is reduced, and the indication of ligament reestablishment is expanded. The ligament reestablishing system comprises a first endosteal hollow channel, a second endosteal hollow channel, a ligament substitute, a first fixing piece and a second fixing piece. A bone penetrating through the near end of the joint and a bone penetrating through the far end of the joint are implanted into the first endosteal hollow channel and the second endosteal hollow channel respectively. The ligament substitute is placed into the first endosteal hollow channel and the second endosteal hollow channel.

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...
