Surgical cutting and binding apparatus

Abstract

The invention provides a surgical cutting and binding apparatus, comprising an upper closed forces clip, a lower closed forces clip, a closed handle, a pushing button and a releasing button. The upper and lower closed forces clips are matched and connected with a pin on one of the closed forces clips by a hook on the closed handle; the pushing button is arranged at the closer end of the apparatus and can slide relative to the closed forces clip so as to push a cutter and trigger matching pins; the releasing button is arranged at the closer end of the closed handle and opens the apparatus when being pressed; the binding apparatus comprises a locking mechanism, when the pushing button of the apparatus dose not return to the initial position, the locking mechanism enables the apparatus not to be opened. The structure of the invention can ensure that the apparatus cannot be opened accidently to cause serious results during the process of triggering, thereby further improving the safety of the apparatus.

Description

technical field [0001] The invention relates to a surgical binding instrument, in particular to a side-type surgical cutting and binding instrument, which belongs to the field of medical instruments. Background technique [0002] Surgical binding instruments are important tools for wound suturing in surgical operations, and there is a trend of eliminating manual suturing at present. Among them, the side-type surgical cutting and binding instrument can cut tissue while closing the wound. This stapler can drive into two rows of staples on both sides of the tissue at the same time, and then use a push knife to cut and separate between the sutured tissues on both sides. At present, this stapler is widely used clinically for side-to-side anastomosis of the stomach and jejunum, as well as operations such as the production of gastric tubes and partial lung resection. [0003] U.S. Patent No. 7,055,730 discloses a side-side type surgical cutting and binding instrument, wherein the...

Problems solved by technology

Such a structure has potential safety hazards, because if the doctor accidentally touches the release button during the firing of the device, the device will be opened halfway. At this time, the wound closure has not been completed, and some staples are not completely closed. It not only caused harm to the patient, but also made the doctor have to take remedial measures, which delayed the operation time and affected the effect of the operation.
