Medical five-axis bone drilling device

Abstract

The invention discloses a medical five-axis bone drilling device. The medical five-axis bone drilling device comprises a frame and a working platform, a bone fixture is arranged on the working platform, a Y-axis movement control mechanism, a rotary shaft movement control mechanism and an overturning shaft movement control mechanism are arranged below the bone fixture, a bone drilling instrument matched with the bone fixture for positioning a bone to be drilled is arranged above the bone fixture and is connected with a Z-axis movement control mechanism and an X-axis movement control mechanism, and a five-axis linkage numerical control system is arranged beside the frame and controls one or more of five axes to move independently or combinationally. The medical five-axis bone drilling device is capable of linearly moving in the X-axis, Y-axis and Z-axis directions and accurately positioning when rotating and overturning, and can be used for processing and cutting bones at multiple angles freely, so that processing precision and working efficiency are improved. The medical five-axis bone drilling device is compact and reasonable in structural design and less prone to bacterium breeding, thereby completely meeting various requirements on medical bone processing.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a medical five-axis bone drilling device. Background technique [0002] In the field of medical scientific research, researchers generally use various processing machine tools used in industry to conduct bone drilling (cutting) cutting experiments, bone tapping experiments and dental carving experiments. Existing various machine tools can only do three-axis linear motion, and cannot perform oblique drilling. Chinese patent CN200610122016.5 discloses a five-degree-of-freedom five-axis parallel virtual axis machine tool, including a fixed table, a moving table, and connecting rods connecting the fixed table and the moving table. The moving table is connected to the fixed table through five connecting rods. The connection between the connecting rod and the moving table is a hinge distributed on the moving table, and the connection between the five connecting rods and the fixed tabl...

Existing various machine tools can only do three-axis linear motion, and cannot perform oblique drilling

Chinese patent CN200610122016.5 discloses a five-degree-of-freedom five-axis parallel virtual axis machine tool, including a fixed table, a moving table, and connecting rods connecting the fixed table and the moving table. The moving table is connected to the fixed table through five connecting rods. The connection between the connecting rod and the moving table is a hinge distributed on the moving table, and the connection between the five connecting rods and the fixed table is a kinematic pair distributed on the fixed table. The movement can also realize rotation and flipping, but because it connects the fixed table and the moving table through the connecting rod, and the electric spindle and the tool are installed on the moving table, the rotation angle of the moving table is affected by the length and direction of the connecting rod itself. and the direction of movement are limited, which makes it difficult to freely adjust the relative position of the electric spindle and the tool for accurate positioning and cutting.

In addition, some machine tools used for medical treatment are difficult to clean due to the unreasonable shape design of the working platform, and they are easy to hide bone debris and breed bacteria. The machine tool environment does not meet the medical requirements

Therefore, there is a lack of medical bone drilling devices specially used for bone processing in the biomedical field on the market.
