Embodiment 1

[0045] The orthopedic composite adhesive material includes a solid component and a liquid component, and the mass ratio of the solid component to the liquid component is 2:1. Solid components include 16.2g polymethyl methacrylate (90wt%), 1.8g furyl aromatic polyamide powder (10wt%), 2g barium sulfate (BaSO 4), 0.1g benzoyl peroxide (BPO); liquid components include 10mL methyl methacrylate, 50uL N,N-dimethyl-p-toluidine (Dmpt), furyl aromatic polyamide powder used in this embodiment The publication number is the high molecular weight furan-based polyamide in Example 1 of the patent application specification CN110256668A. Among them, barium sulfate is used as a contrast agent, which plays a contrasting role, and benzoyl peroxide belongs to an initiator, which is used to initiate a second polymerization reaction during use. N,N-Dimethyl-p-toluidine catalyzes BPO to generate free radicals, which belongs to the activator. The molecular weight of polymethyl methacrylate in this e...

Embodiment 2

[0051] The difference between this example and Example 1 is that the mass of polymethylmethacrylate is 17.1g (95wt%), and the mass of furyl aromatic polyamide powder is 0.9g (0.05wt%).

[0052] At a temperature of 23°C and a humidity of 40%, it was left to stand for 3 minutes and then cured for 10 minutes to obtain a bioactive and antibacterial orthopedic medical composite adhesive material.

Embodiment 3

[0054] The difference between this example and Example 1 is that: the orthopedic medical composite adhesive material with bioactivity and antibacterial properties was obtained after standing for 3 minutes at a temperature of 21° C. and a humidity of 60% and then cured for 15 minutes.

Abstract

The invention discloses an orthopedic composite adhesive material, which relates to the technical field of medical materials. The invention includes a solid component and a liquid component, and the solid component includes polymethyl methacrylate, furyl aromatic polyamide, contrast agent and Initiator; the liquid component includes methyl methacrylate. The present invention also provides a preparation method of the above-mentioned orthopedic composite adhesive material. The beneficial effect of the present invention is that: the orthopedic medical composite adhesive material raw material of the present invention is mixed with a certain proportion of furyl aromatic polyamide material, which belongs to bio-based material, has high biological safety, has good biological activity, and can effectively reduce tissue Heat damage, exothermic temperature below 60°C, and has excellent antibacterial properties.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to an orthopedic composite adhesive material and a preparation method thereof. Background technique [0002] Acrylic resin bonding materials have been used in orthopedics for more than 50 years. Conventional polymethyl methacrylate (PMMA) bonding materials include a powder (PMMA powder, developer, catalyst, and some contain colorants and antibiotic ingredients) and a liquid agent (MMA, accelerator, polymerization inhibitor, some containing coloring agent), the powder and liquid agent are mixed and stirred during use, and then the orthopedic adhesive material is delivered or introduced to the required part through the device, and the mixture passes through After the porridge stage, sticky silk stage, dough stage, and curing stage, it can be solidified and shaped, and it can play the role of bone filling and joint prosthesis fixation. [0003] PMMA adhesive material is the ...
