Problems solved by technology

If the firing pushrod is forward relative to the installation position, some titanium nails of the cartridge assembly may be withdrawn in advance; when the firing pushrod is backward relative to the installation position, the staple cartridge assembly cannot be connected to the firing pushrod, resulting in the failure of the staple cartridge assembly. Cannot be opened after closing; causing inconvenience to the installation of the staple cartridge assembly

Abstract

The invention relates to an adapter used for an endoscopic stapler. The adapter includes a shell, a nail bin connection rod, a transmission component, a drive connection block, a striking push rod, afirst trigger element and a first contact switch; the first trigger element is fixedly arranged on the drive connection block, and the first contact switch is fixedly arranged on the shell; the transmission component transmits power of a motor to the drive connection block, so that the drive connection block moves in the axial direction of the nail bin connection rod; the drive connection block drives a striking push rod to move in the axial direction of the nail bin connection rod; the striking push rod moves to the first contact switch relative to the nail bin connection rod so as to triggerthe first contact switch, and the first contact switch transmits a signal to a control unit of the endoscopic stapler. According to the adapter, the first contact switch transmits the signal to the control unit of the endoscopic stapler, the control unit can controls the motor to stop running, the striking push rod thus can be accurately kept at an installation position, and installation of the nail bin component is convenient to achieve. The invention further relates to the endoscopic stapler.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an adapter for a laparoscopic stapler and a laparoscopic stapler. Background technique [0002] At present, minimally invasive surgery occupies an important position in surgery. Laparoscopic stapler is a commonly used surgical instrument in minimally invasive surgery. The working principle of the laparoscopic stapler is to clamp the staple cartridge assembly at a specific position near the lesion, perform resection, and suture at the same time. [0003] Generally, a laparoscopic stapler includes a staple cartridge assembly, an adapter and a handle, wherein the staple cartridge assembly is detachably mounted on the adapter, and the staple cartridge assembly is detachably connected to the firing push rod and the staple cartridge connecting rod of the adapter. In traditional laparoscopic staplers, the firing push rod can move axially relative to the connecting rod of the staple ...
