Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medicine, in particular to a bone repair bracket. Background Art
[0002] At present, many clinically used nano-hydroxyapatite-polymer composite bone repair materials have good biocompatibility and over-induction, can be degraded and absorbed by human body, and their strength is still lower than that of cancellous bone, which greatly limits their application. The existing bone repair scaffolds have no drug filling function, are difficult to be absorbed by patients, have low biocompatibility, are not conducive to the treatment of patients, and seriously affect the recovery time of patients. Moreover, since the structural filling agent cannot adapt to the human body's own bones, it is not conducive to bone repair and growth. Therefore, we have introduced a bone repair scaffold. Utility Model Content
[0003] The main purpose of the utility model is to provide a bone repair bracket, which can effectively solve the problems in the background technology.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0005] A bone repair bracket comprises a fixing plate, a surface of which is provided with a plurality of molecular pores, a fixing groove is provided at the upper left part and the upper right part of the fixing plate, and four fixing grooves are provided, a connecting frame is fixedly connected to the middle part of the outer side of the fixing plate, a surface of the connecting frame is provided with a plurality of filling grooves, and a plurality of the filling grooves are filled with drugs, a front end and a rear end of the connecting frame are provided with a plurality of anti-slip grooves, and the connecting frame is fixedly connected to the middle part of the outer side of the fixing plate.
[0006] Preferably, the plurality of filling slots are equidistantly distributed in a long rectangular structure.
[0007] Preferably, the plurality of filling grooves are all in a conical structure.
[0008] Preferably, several of the molecular pores are in a honeycomb structure.
[0009] Preferably, a plurality of the filling grooves are connected to the interiors of a plurality of molecular pores.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. By filling drugs in several filling grooves, several drugs are made of porous nano-hydroxyapatite composite materials, and the patient's stem cells are inoculated on the porous nano-hydroxyapatite composite materials, the strength of the bone repair material is avoided to be reduced. Since several filling grooves are equidistantly distributed in a long rectangular structure, the filling area of the therapeutic drug is increased, which can self-repair in the body, resist bacterial infection, and shorten the patient's recovery time;
[0012] 2. By implanting the fixation plate into the human body, new bone cells will enter several molecular pores of the fixation plate, divide and proliferate in several molecular pores, and as the new bone cells proliferate, the fixation plate is degraded and eventually completely replaced by new bone cells. Since several molecular pores are in a honeycomb structure, the biocompatibility of the bone repair material is improved, and the use effect is good. BRIEF DESCRIPTION OF THE DRAWINGS
