Background

Basic surgical instruments are basic surgical instruments, and are classified into various types according to their structural and functional characteristics. Familiarity and the ability to use surgical instruments are the most fundamental requirements for the surgeon.

For example, medical needles are instruments used for suturing various tissues, consisting of three basic parts: needle tail, needle body and needle point. It is classified into a round needle and a triangular needle according to the shape of the needle tip. Round needles are classified into 1/2 and 1/3 radians according to their curvature, and the larger is usually used in deep tissues. The front half part of the triangular needle is triangular and sharp, and is used for suturing tough tissues such as skin, cartilage, ligament and the like, and the injury is large, so the round needle is applied to the tissues except the tissues. In addition, when the curved needle is used for suturing, the force application direction is consistent with the arc direction of the curved needle, the curved needle is pulled out of the tissue along the radian of the curved needle when the needle is pulled out, and otherwise the curved needle is easy to break.

In addition, VHDL is mainly used to describe the structure, behavior, function, and interface of a digital system. Except for the fact that it contains many statements with hardware features, the linguistic form, description style, and syntax of VHDL are very similar to a general computer high-level language. The structural features of the VHDL program are to divide an engineering design, or design entity (which may be a component, a circuit module or a system) into an external (or visible part, and port) and an internal (or invisible part), which relate to the internal functions and algorithm completion of the entity. After an external interface is defined for a design entity, once its internal development is complete, other designs can invoke the entity directly. This concept of dividing the design entity into inner and outer parts is the fundamental point of VHDL system design.

VHDL has powerful language structure, and can describe complex logic control by simple and clear source code. The method has a multi-level design description function, is refined layer by layer, and can directly generate circuit level description. VHDL supports the design of synchronous, asynchronous, and random circuits, which is incomparable with other hardware description languages. VHDL also supports various design methods, both bottom-up and top-down; the method supports both modular design and hierarchical design.
