Embodiment Construction

[0074] In order to better explain the present invention, the present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments.

[0075] figure 1 It is an exploded view of a specific embodiment of the present invention. Figure 2a is a cross-sectional view of a bone holder in a specific embodiment; Figure 2b to Figure 2d It is a cross-sectional view of bone holders and sliding covers in multiple embodiments combined. As shown in the figure, a bone implant includes a bone holder 1 , a sliding cover 2 , a pressure rod 8 , and a support rod 7 . The bone holder 1, the sliding cover 2, the pressurizing rod 8 and the support rod 7 are all cylindrical structures with a longitudinal length, and the respective sides of the bone holding body 1 and the sliding cover 2 all include longitudinal recesses. Groove 3 and 4, the mating surface 16 that extends longitudinally and the outer surface 17 that joins with described mating surfa...

Abstract

The invention provides a bone grafting instrument and an application method thereof. The bone grafting instrument comprises a bone holding body, a slip cover, a pressurizing rod and a support rod, wherein the bone holding body has a cylinder structure with longitudinal length; the bone holding body and the slip cover are combined into an enclosed hollow cylinder structure; the pressurizing rod and the support rod can be combined into a tightly contacted cylinder structure which is accommodated in the enclosed hollow cylinder structure formed by the bone holding body and the slip cover; and the pressurizing rod can be inserted into a groove of the bone holding body through both sides of the support rod in the bone grafting process, so that bone materials can be pushed in the charging process, and lateral bone grafting can be performed in the bone grafting process. The invention further provides an application method of the bone grafting instrument for lateral bone grafting. The bone grafting instrument can be applied to positive bone grafting.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to a bone graft device and a method for using the bone graft device. Background technique [0002] Most of the bone grafts currently on the market use injection to fill the bone tunnel, but for some bone tunnels with side wall defects, for example, during the revision process after the reconstruction of the anterior cruciate ligament fails, when the interface screw is removed, Because the thread of the interface screw inevitably leads to the expansion of the bone tunnel and the bone defect in the wall of the bone tunnel, it is necessary to perform bone grafting on the femoral or tibial side. There are no instruments for bone grafting of sidewall defects of the bone tunnel, so the first surgery is usually performed first, and the bone tunnel (including the hole for the interface screw fixation and the bone caused by the removal of the interface screw) is injected to fill the bone graft...
