Surgical knives are one of the important tools for surgery, treatment and rehabilitation in the medical field, and surgical knife handles are an important component of surgical knives for connecting the blade and the hands of the operator, so that the machining accuracy and comfort thereof have an important influence on the surgical procedure and the therapeutic effect.
In the surgical knife handle machining process, a clamp is required to be used for fixing and positioning the knife handle so as to ensure the machining precision and consistency, the design and the use of the clamp have significance for improving the production efficiency, reducing the cost, ensuring the product quality and shortening the manufacturing period, the early surgical knife handle machining clamp can adopt a simple mechanical arm or manual operation to machine by positioning and fixing the knife handle, however, with the continuous development and progress of the medical technology, the design and the use of the surgical knife handle machining clamp are also continuously improved and perfected, because the knife handle is smaller as a whole and requires higher machining precision, and meanwhile, different clamps are required to clamp the surgical knife handle in different machining steps, so that a positioning clamp with high clamping precision and a plurality of clamps for matched clamping is required.
The surgical knife handle is long-strip-shaped, the position needing finish machining is often located in the middle part and the head part of the knife handle, the part precision is high when the surgical knife handle is close to the middle part, clamping and positioning are needed to be carried out in the middle part of the part, positioning is convenient, large positioning force can be achieved at the same time, the clamping jaw is driven to be achieved by adopting an oil cylinder structure in the middle part, but when the oil cylinder clamping jaw structure is positioned in a clamp, the cylinder body part of the oil cylinder is usually subjected to position limiting, the mounting structure is stable, but when the oil cylinder clamping jaw works, a piston rod in the cylinder body needs to be pushed to advance through a high-pressure oil way, then a piston rod connecting piece drives a pull rod to move, driving of the jaw part is achieved through the pull rod, and huge accumulated errors are generated between the positioning position of the jaw and the cylinder body due to linkage of a plurality of working procedures, so that the positioning precision of the oil cylinder clamping jaw structure used on the clamp is greatly limited. The high-precision processing of the surgical knife handle parts cannot be completed.
In addition, when the scalpel handle is processed, besides high-precision processing of the joint of the scalpel handle and the scalpel head, the scalpel handle is required to be processed in a sand blasting mode on the scalpel body portion of the scalpel handle, because a large amount of dust is generated in a traditional sand blasting process, the sand blasting operation of the scalpel handle is required to be processed in a single process step, the scalpel handle is required to be detached from the positioning clamp, then the clamping structure specially used on sand blasting equipment is used for re-clamping processing, sand blasting processing is performed, the process operation is complex, additional positioning clamps are required, and processing cost is greatly increased.
