Molding device for skull defect model with definite depth and method

Abstract

The invention discloses a molding device for a skull defect model with definite depth. The molding device comprises a drilling bit, a sleeve and a control source, wherein the control source includes,but not limited to, a power line, the drilling bit penetrates through the sleeve, a connecting member is arranged between the drilling bit and the sleeve and includes, but not limited to, a setscrew,the sleeve is of a hollow cylindrical structure, the diameter of the sleeve is greater than that of the drilling bit, the length of the sleeve is smaller than that of the drilling bit, and the sleeveis made of a hard material. The molding device is simple in structure, has extremely high operability, has low requirements on operating experience of operators and is suitable for learning use of beginners, definite depth of drilling can be guaranteed, too deep or shallow depth of drilling is avoided, supporting to a skull during drilling is excellent, and the circumstance that collapse breakingof the skull is caused due to the fact that stability during drilling is broken is effectively avoided. A molding method for the skull defect model with the definite depth is simple and easy to learn.The invention is extensively applicable to medical care industry.

Description

Technical field [0001] The invention relates to the technical field of medical equipment, in particular to a model building equipment and a method for determining a depth of a skull defect model. Background technique [0002] At present, due to many diseases such as osteoporosis, pathological fractures, traumatic fractures, etc., there are problems that need to promote osteogenesis and inhibit osteogenesis. Therefore, there are more and more researches on osteogenesis. This research field involves basic osteogenesis research. Osteogenesis studies of biomaterials, osteogenesis studies of new drugs, studies of new bone growth after tumor resection, etc. In these osteogenesis-related experiments, the recognized animal model is the skull defect model of rats or rabbits, that is, the use of electric drills in rats Or a small defect was ground out on the rabbit's skull and then filled with related drugs or materials to observe the difference with the control group. [0003] In this proc...

[0005] Another example is that CN201180010409 discloses a device for treating brain diseases and its implementation method. In the drilling process, the requirements for the drilling are extremely high, and the requirements for the aperture are also extremely high. The requirements for the stability of the skull after drilling Higher, and the high-precision drilling device in the prior art also requires high operating experience, so for the operator, it has a very high failure rate
