End executor, nail box assembly thereof and surgical operating instrument

Abstract

The invention relates to the technical field of medical apparatuses and instruments, and discloses an end executor, a nail box assembly thereof and a surgical operating instrument. The nail box assembly comprises a nail bin, a nail push slide block and a cutter. The nail push slide block is arranged on the nail bin in a slidable mode. The cutter is located in a cutter groove formed in the nail bin. The end, away from the nail outlet face of the nail bin, of the cutter is connected to the nail push slide block in a pivoted mode through a pin shaft, the axis of the pin shaft is perpendicular to the cutter groove, and the end face, facing the near side, of the cutter is a push face abutting against a cutter push rod of the surgical operating instrument. An elastic reset piece is arranged between the cutter and the nail push slide block. The blade part of the cutter is contained in the cutter groove of the nail bin under the acting force of the elastic reset piece when the cutter does not bear thrust of the cutter push rod. The cutter can rotate to the cutting state around the pin shaft when bearing thrust of the cutter push rod. The cutter of the nail box assembly is used only once, the sharpness of the blade part of the cutter is ensured when an operation is performed through the surgical operating instrument, and therefore operation quality is improved, and medical risks are lowered.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an end effector, a nail box assembly thereof, and a surgical instrument. Background technique [0002] Surgical instruments under the laparoscope have less trauma to the patient, and the surgical effect is good, which can greatly reduce the pain caused to the surgical patient. [0003] The surgical instrument includes an operating handle and an end effector. The operating handle has a fixed handle for the operator to hold. Side) is connected to the end effector through the elongated body; the end effector includes a nail anvil assembly and a nail magazine assembly, wherein the nail magazine assembly includes a nail magazine for carrying staples. [0004] Surgical instruments are equipped with cutting knives for cutting human tissue at the surgical site, and the sharpness of the cutting knives is a key parameter for cutting and suturing. [0005] However, in the surg...

AI Technical Summary

Problems solved by technology

[0005] However, in the surgical instruments in the prior art, the nail magazine assembly in the end effector is a disposable product, but the cutting knife needs to be reused

The repeated use of the cutting knife will seriously affect the sharpness of the cutting blade, thereby reducing the quality of the operation and increasing certain medical risks
