Cavity mirror surgical incision anastomat with replaceable nail bin

Abstract

The invention relates to a cavity mirror surgical incision anastomat with a replaceable nail bin. The cavity mirror surgical incision anastomat comprises an anastomat body, an executing head, an extension pipe connecting the anastomat body and the executing head, and an actuating mechanism for controlling the movement of the executing head, wherein the executing head is composed of an executing frame, a slide bar, a nail bin and an anvil, and the nail bin comprises a nail bin shell, a nail pushing block, a nail pushing sliding plate and anastomosis nails. The nail bin shell is internally provided with a nail slot, a nail pushing hole, a sliding plate groove and a push broach groove, wherein the end surface of the anvil is provided with an anastomosis nail forming slot corresponding to theanastomosis nail position in the nail bin and a cutting slot corresponding to the push broach groove inside the nail bin shell, a cutter is installed in the push broach groove of the nail bin shell, and an arc-shaped chute is arranged on the near end of the nail bin shell. When the nail bin is in use, the slide bar moves from the near end of the nail bin to the far end, and the nail pushing sliding plate can push the anastomosis nail out of the nail slot while pushing the nail pushing block to move in the nail pushing hole by means of the inclined surface of the nail pushing sliding plate. The cavity mirror surgical incision anastomat can be used more conveniently and safely, is more convenient to install and detach the nail bin, and reduces the surgery cost.

Description

technical field [0001] The invention relates to an endoscopic surgical cutting stapler used in thoracoscopic surgery, in particular to an endoscopic surgical cutting stapler with a replaceable staple cartridge, which belongs to the field of medical instruments. Background technique [0002] In laparoscopic surgery, laparoscopic surgical cutting and staplers are usually used for cutting and anastomosis of the esophagus, stomach, duodenum, small intestine, colon, rectum, appendix, gallbladder, pancreas and spleen in the digestive tract. Resection and anastomosis of the lung and trachea in the respiratory tract are also used in the resection and anastomosis of the bladder and uterus in the genitourinary system, which can reduce operation time and improve operation quality. [0003] Existing laparoscopic surgical cutting staplers are related to various laparoscopic surgical cutting staplers introduced in national patents 20080308602, 20090206124 and 20090206123. When using a la...

Problems solved by technology

Another unsatisfactory aspect of this style of endoscopic surgical cutting stapler is that, as described in US Patent 20090206123, the end connector of the disposable loading device may inadvertently cut from the endoscopic surgical stapler's elongated body Detachment, resulting in endoscopic surgical cutting stapler failure or inoperability, so US Patent 20090206123 also proposes that the disposable loading device can be installed on the elongated main body along a direction that is neither collinear nor parallel to the elongated main body axis, and also It is proposed to add threads, or a pawl mechanism, or a snap-fit ​​device to the end connector of the disposable loading device to ensure that the disposable loading device can be reliably connected to the elongated body of the laparoscopic surgical cutting stapler

Since in laparoscopic surgery, the diameter of the elongated body of the laparoscopic surgical cutting stapler is 12 mm to 13 mm, the processing and assembly of the end connector of such a complex disposable loading device is difficult and the quality is difficult to guarantee, It is also very troublesome to repeatedly assemble and disassemble during the operation, and the total cost is also quite high
