Embedded-assembled type medical forceps

Abstract

The invention discloses embedded-assembled type medical forceps. A metal pressure injection molding method is used for forming a male piece and a female piece of the forceps respectively. A notch is formed in a gill portion on the upper side of the female piece, a gill portion of the male piece is embedded into a gap of the gill portion of the female piece, and a protruding locating cylinder at the bottom of the gill portion of the female piece is embedded into a counter bore in the bottom of the gill portion of the male piece for locating; the female piece is rotated clockwise until a forceps head of the female piece and a forceps head of the male piece are combined, and a fixing screw is used for screwing up the female piece and the male piece, so that the requirement for free opening and closing of a forceps opening of the forceps is met. According to the embedded-assembled type medical forceps, the assembling structure of the female piece and the male piece is changed, so that the precision in rotation and the vertical swing degree of the female piece and the male piece are guaranteed and controlled; then the fixing screw is used for fixing the female piece and the male piece, in this way, it can be ensured that the forceps smoothly rotate after being assembled, it can also be ensured that the swing quantity of the forceps in the using process is not large, and the clamping precision of the forceps is ensured.

Description

technical field [0001] The invention relates to the technical field of medical device manufacturing, relates to a gill-piercing medical forceps product, and in particular to an inlaid medical forceps which changes the original gill-piercing medical forceps. Background technique [0002] At present, most of the medical pliers used in hospitals are gill-piercing medical pliers, and the processing method of gill-piercing medical pliers is to cut the metal bar first, and then heat the cut bar to 700~800 degrees. It is pressed and formed by a special pressing cavity abrasive tool, and after the original and multiple punching, rough pressing, fine pressing, and blank shaping, the assembly size of the pliers is completed through milling, pliers, and grinding, and then passed Heating, reaming, piercing the gills, and then flattening, shaping, drilling, and installing rivets to complete the assembly of the entire pair of pliers. [0003] The processing of this kind of gill-piercin...

AI Technical Summary

Problems solved by technology

[0003] The processing of this kind of gill-piercing medical forceps requires a lot of manpower, material resources, and financial resources, and is accompanied by defects such as large energy consumption, large environmental pollution, and low production efficiency. After high-temperature heating and processing, it is easy to cause over-burning and overheating of the material, resulting in cavities and trachoma inside the pliers blank material, increasing the risk of fracture during use of the finished pliers, and in severe cases, it may be accidentally broken during the operation. medical malpractice
