Abstract

The invention relates to a built-in artificial limb connecting device. The built-in artificial limb connecting device comprises a bone stump fixing sleeve which is of a tubular structure with two open ends, wherein a first joint part is formed at a first end of the bone stump fixing sleeve, a bone stump fixing cavity is formed in a second end of the bone stump fixing sleeve, and the bone stump fixing cavity is configured to be arranged outside a stump bone in a sleeving mode and connected with the stump bone in a fastened mode; and a bone stump fixing handle, wherein the bone stump fixing handle comprises a broach, a second joint part and an external connection part which are integrally connected, the broach of the bone stump fixing handle penetrates through the first end of the bone stump fixing sleeve and then is fixedly connected with the first joint part of the bone stump fixing sleeve through the second joint part, the broach of the bone stump fixing handle is used for being inserted into a marrow cavity of stump bone and is fixedly connected with the marrow cavity of the stump bone, and the external connecting part of the bone stump fixing handle is used for being connected with an external artificial limb. The built-in artificial limb connecting device can be widely applied to patients subjected to amputation for different reasons, integration of a connector and the stump bone is achieved, and the amputated patients can conveniently replace different more-comfortable external artificial limbs according to own requirements.

Description

technical field [0001] The invention relates to a prosthetic connection device, in particular to a built-in prosthetic connection device for amputee patients to choose different prostheses arbitrarily, and belongs to the technical field of medical devices. Background technique [0002] Amputation, as the name suggests, is the removal of lifeless or life-threatening limbs due to local diseases. Amputation is specifically the removal of part of a limb through one or more bones. The reasons for amputation are gradually changing, and amputee due to peripheral vascular disease or concurrent diabetes has become more and more common, especially in Western countries (for example, in the United States, it accounts for 50% of the incidence of amputation), rising to The number one cause of amputation has also been on the rise in my country in recent years. In daily life, people will inevitably encounter some unexpected situations (such as major traffic accidents), and may also suffer ...
