Staple bin assembly and stapler using same

Abstract

The invention relates to a staple bin assembly and a stapler using the same. The staple bin assembly comprises a staple bin sleeve, a joint-cutting assembly, a driving assembly, a staple bin and a staple pushing plate, wherein the driving assembly comprises a driving seat and a driving gear; the driving seat can move in the staple bin sleeve in the up-down direction; a guiding column is arranged at the upper end of the driving seat; the driving gear is provided with a chute; the guiding column slides in the chute; the joint-cutting assembly comprises a cutter slider, a staple pushing slider and a cutter toothed ring; the lower part of the cutter slider is a barrel, and the upper end of the cutter slider is a cutting head; the staple pushing plate and the staple pushing slider can be slidably sleeved on the outer side of the barrel of the cutter slider in the up-down direction; the cutter toothed ring is arranged at the bottom of the staple pushing slider; and the lower end of the cutter toothed ring is meshed with the driving gear. A transmission assembly of the stapler can push the driving seat of the staple bin assembly under the action of a trigger. A stitching staple forming effect is good, tissues are cut smoothly, a surgical effect is good, the surgical efficiency is high, and the required triggering force is small; the staple bin assembly is safe and reliable; and the normal surgery can be guaranteed, so that the staple bin assembly and the stapler using the same are suitable to be popularized and used.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a staple cartridge assembly and a stapler using the same. Background technique [0002] Stapler is a medical device that replaces traditional manual sutures in surgical operations. Among them, tubular staplers are widely used in human digestive tract operations, such as the ends of the esophagus, stomach, duodenum, and small intestine in the digestive tract or End-to-side anastomosis. Especially in the case where the operated interface site is relatively short or the field of vision is unclear, it is more necessary to use a stapler to close the wound. In surgical operations such as digestive tract reconstruction, the use of medical staplers to assist incision suture has the advantages of simple operation, rapid suturing, and basically no side effects and complications. Moreover, such devices can shorten operation time and improve operation efficiency. The specific method of u...

Problems solved by technology

[0003] The staple cartridge assembly of the tubular stapler currently used clinically, the suturing and cutting actions are performed simultaneously, and the cutting direction is the same as the staple output direction of the staple. The cutting knife must cut through the pad knife ring to complete the cutting action. This traditional anastomosis method of the staple cartridge assembly is likely to cause risks such as poor staple formation, staples falling to one side, and continuous tissue cutting, which increases the pain of the patient and affects the operation. Effect

[0004] It can be seen that there are obvious deficiencies and defects in the structure, method and use of tubular staplers in the prior art, and further improvement is urgently needed
