Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the drawings and implementation process.

[0030] see figure 1, the present invention designs a kind of loading square suitable for the implantation experiment in the bone of small experimental animal and the built-in loading device used in this process, wherein the loading device consists of base body (1), spacer (2), compression spring (3) and retention cap (4) form. When carrying out animal experiments, the matrix is ​​implanted from the outside of the femur or tibial backbone of the animal, runs through the entire bone cavity, and passes through the inner side of the backbone, while ensuring that the axis of the base (1) is basically perpendicular to the axis of the backbone. After the matrix (1) is implanted, install the spacer (2) and the spring (3) in sequence on the inside, and then screw the retaining cap (4) into the external thread (201) of the matrix (1) until it is retained...

Abstract

The invention discloses an endosteal implantation loading method and a built-in loading device for a small laboratory animal. The device consists of a matrix, a gasket, a spring and a position fixing cap. The matrix is divided into an integration section with taper and a fixing section with an external screw thread; the gasket is a step short shaft with a center hole; and the upper part of the position fixing cap is provided with a circular ring cylinder and the lower part of the position fixing cap is provided with a pentagonal prism with a screwed hole. During the experiment, the matrix is implanted into a backbone prepared hole from the outside, the integration section runs through the whole bone cavity, the fixing section protrudes from the inside and then the gasket, the spring and the position fixing cap are sequentially arranged on the fixing section, wherein the position fixing cap is in screw thread fit with the matrix body; and when the position fixing cap is screwed down, the spring needs to be compressed until the circular ring cylinder of the position fixing cap is gradually close to the step short shaft of the gasket to form a gapless embedded structure. Compared with the existing external frame-type loading method and device, the endosteal implantation loading method and the built-in loading device have the characteristic of generating a load amount required by the experiment by designing the deformation amount of the spring and have the advantages that the method and the device are accurate to load and are easy to control; the wound is small; and the device is difficult to interfere.

Description

technical field [0001] The invention relates to a loading method and loading device for built-in implantation of small experimental animals, belonging to the related field of intraosseous implantation animal experiments. Background technique [0002] In the 1960s, an orthopedic expert in the Swedish Nobel Laboratory The research team led by the professor put forward the theory of osseointegration, and successfully developed a modern oral implant system for clinical application. In 1965, the world's first oral implant surgery was completed. Since then, this bionic denture has been clinically obtained. Rapid development and application, and successive reference to the fields of orthodontic anchorage, craniomaxillofacial trauma reconstruction, prosthetic finger attachment and even residual limb repair, directly promoted the development of these disciplines and the improvement of clinical diagnosis and treatment level. [0003] However, the classical theory of osseointegration...
