Embodiment approach

[0053] According to one embodiment, the plug connector comprises a bayonet connector 69 rotatably supported by the anoscope distal portion 18 . The bayonet connector 69 includes a distal bayonet key 70 capable of removably engaging a corresponding bayonet seat 71 formed in the rectal stump closure plug 4 and protrudes proximally into the anoscope working channel 17 and can be operated by a surgical The actuating portion 72 of the grasping device grasps transanally and rotates. The actuating portion 72 has a planar plate-like shape and the bayonet connector 69 enables the actuating portion 72 to be aligned with the angled stem 25 of the anoscope window ring 24 in the plug coupled configuration so as not to obstruct the visual access ( Figure 18 , 19).

[0054] The distal plate 6 comprises a distal plug 7 arranged distally of the rectal stump closure plug 4 and having a circumferential second tightening surface 53 .

[0055] Similar to the rectal stump closure plug 4, the sec...

Abstract

The invention relates to a surgical device for use in rectal resection surgery comprising a rectal stump closure device (1) having a circular anal dilator (2) defining a passage opening (10) an anoscope (3), which can be inserted through the channel opening (10) of the circular anal dilator (2) and has a distal portion (18); a rectal stump closing plug (4), which has a circumferential third A tightening surface (30), the first tightening surface enables the rectum (46) to be tightened against the first tightening surface from the outside of the rectum (46); plug connector (5), which connects the rectal stump The closure plug (4) is removably connected to the distal portion (18) of the anoscope (3).

Description

technical field [0001] The present invention relates to surgical devices and methods for low proctectomy, particularly in the treatment of patients with small or medium rectal carcinoid tumors. Background technique [0002] One existing surgical technique for performing a low rectal resection is known as low anterior resection (LAR), which can be performed either through an open procedure or using the Knight-Griffen technique, also known as the double staple technique, with performed laparoscopically. The rectum is mobilized relative to the sacrum under general anesthesia, which involves cutting the lateral ligaments under direct laparoscopy or by open surgery. The bowel is severed, for example, between the sigmoid colon and the rectum using a linear stapler. The lower rectum (containing the tumor) is then transected using a linear stapler or a Kaitu stapler. [0003] In this way, a stapled proximal colon stump and a stapled rectal stump are formed, which need to be joine...
