Surgical nailing device

Abstract

The invention discloses a surgical nailing device, which comprises a fixed handle, a bracket, a nail anvil, a percussion handle, a nail push rod, a nail cabin push rod, a nail cabin, a nail push sheet, a linkage percussion mechanism, a releasing assembly and only one brake plate, wherein the bracket is fixed on the fixed handle; the nail anvil is fixedly arranged on the far end of the bracket; the percussion handle is pivoted on the bracket; the nail push rod and the nail cabin push rod are relatively and movably arranged on the bracket; the nail cabin is formed at the far end of the nail cabin push rod; the nail push sheet is arranged in the nail cabin, and is pressed against the nail push rod; the linkage percussion mechanism is arranged in the fixed handle; the releasing assembly is used for releasing the linkage percussion mechanism; the linkage percussion mechanism comprises a connecting rod group for pushing the nail cabin push rod to move, and a percussion connecting rod used for pushing the nail push rod to move; both the connecting rod group and the percussion connecting rod are driven by using the percussion handle; and the brake plate is used for switching between a state in which the percussion handle is used for driving the connecting rod group to act and a state in which the percussion handle is used for driving the percussion connecting rod to act. The surgical nailing device has the beneficial effects of simple structure and convenience in assembling.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a linear surgical stapling device. Background technique [0002] At present, when human tissues such as the esophagus, stomach, and intestinal tract are surgically anastomosed, a surgical stapler is often used for anastomosis, and a linear stapler is a relatively important one. In the prior art, with reference to U.S. Patent No. 7,407,076, a linear stapler is described, which is used to close the wounds of the digestive tract and visceral tissues. The nail anvil and the staple magazine for operation, the transmission device arranged in the bracket and used to push the staple magazine and the nails in the staple magazine, and the firing handle pivotally arranged on the bracket through a rotating shaft and connected to the transmission device, the transmission device It includes two staple cartridge push rods for pushing the staple cartridge to move toward the nail anvil, and a ...
