Abstract

The invention discloses a method for preparing porous titanium-tantalum artificial bone and joint and products thereof, and belongs to the field of biological materials. The method comprises the following steps: S1, grinding to-be-bonded surfaces of a titanium alloy sheet and a tantalum sheet, and performing ultrasonic washing sequentially with acetone, alcohol and deionized water; S2, fitting the titanium alloy sheet and the tantalum sheet, heating to 850-1050 DEG C, insulating for 20-40 minutes, pressurizing to perform plastic deformation, and air-cooling to room temperature to form metallurgic bonding between the two materials; S3, quickly preparing pores having a pore size of 300-600mu m in a compound plate by utilizing a solid laser; S4, preparing various artificial bones and joints from the titanium-tantalum compound plate by utilizing a thermal forming technology; and S5, performing alkali and pre-calcifying treatment to improve the biocompatibility of the compound material. Compared with a traditional explosive compound method, the hot-rolling compound method is safer, controllable, convenient and firm in bonding. The product has relatively high biocompatibility.

Description

technical field

[0001] The invention belongs to the technical field of biomaterials, and more specifically relates to a method and product for preparing a permanent medical porous metal implant, in particular to a preparation of porous titanium tantalum for medical implants suitable for replacing human bones and human joints Methods and products for artificial bones and artificial joints. Background technique

[0002] At present, porous medical metal implant materials have important and special uses in the fields of bone tissue trauma, femoral tissue necrosis, spinal surgery, and dental implants. The porous structure is conducive to the ingrowth of the surrounding biological tissue, so that the implant material and the surrounding bone tissue form a firm mechanical lock, which is conducive to the stability of the implant material in the human body. On the premise of ensuring the mechanical properties of the implanted material, the porosity of the implanted material should b...
