A stapler with double insurance mechanism

Abstract

The invention discloses a stapler with double insurance mechanisms, which belongs to the technical field of medical devices. The main points of the technical solution include a casing and an anvil seat, wherein a power mechanism is arranged inside the casing, and the bottom of the power mechanism starts from A firing handle and a closing handle are hinged in sequence from left to right. Both the firing handle and the closing handle penetrate through the casing and extend to the outside of the casing. The right side of the power mechanism is provided with a reset button, which penetrates through the casing. And extend the outside of the casing, the present invention can adjust the distance between the fixed tube and the circular tube according to the actual operation situation by setting the adjusting device, so as to change the overall length of the stapler, making the stapler more convenient to use, not easy to use When the distance is insufficient or the overall length of the stapler is too long, the second spring can squeeze the telescopic rod, which increases the stability of the adjustment device and prevents the stapler from breaking out of the annular groove during use.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, to a stapler with double safety mechanisms. Background technique [0002] The linear stapler is a commonly used surgical stapler. It is often used to close the wounds of the digestive tract and visceral tissues. For the nail anvil and the staple magazine that perform the suturing operation, the transmission device that is arranged in the splint of the nail abutment seat for pushing the staple cartridge and the nails in the staple magazine is pivotally arranged on the splint of the nail abutment seat through a rotating shaft and connected The limit handle and the push nail handle of the transmission device include two nail cartridge push plates arranged on the inner side of the two nail seat splints for pushing the staple cartridge to move along the nail block splints to the direction of the anvil and set on the The nail pushing plate between the two staple cartridg...
