Detailed Description
The utility model is described in detail below with reference to the accompanying drawings:
as shown in fig. 1-5: a pouch anastomosis structure of a pouch anastomat for endoscopic cutting comprises an upper clamp part 1 and a lower clamp part 2; the proximal ends of the upper forceps part 1 and the lower forceps part 2 are hinged with each other; a cutting knife guide groove extending along the far and near direction is arranged on the anastomotic surface of the upper forceps part 1 or/and the lower forceps part 2; wherein, the upper forceps part 1 and the lower forceps part 2 are divided into a left part and a right part by a cutter guide groove, wherein, one part has a structure of an anastomotic component 3 for realizing anastomotic nail anastomosis, and the other part has a structure of a purse string suture component 4 for realizing purse string anastomosis;
the specific structure and the using method of the anastomosis mechanism of the endoscope cutting anastomosis purse-string device are all in the prior art, and are disclosed in publication number 213156149, and the utility model is not repeated.
An elastic buckling structure is arranged on the purse-string pin pushing piece in the purse-string stitching member, and comprises a base 61, a limit column 62 and an elastic column 63; the limiting columns and the elastic columns are arranged on the base, two limiting columns are arranged and are respectively arranged at two sides of the limiting columns;
a limiting hole 64 is formed in the outer side of the limiting column; and a limiting lug 65 matched with the limiting groove is arranged at the outlet of the purse-string rivet hole corresponding to the purse-string rivet pushing piece.
In the process of discharging the purse string nails, the elastic buckle structure moves forward synchronously, and the elastic column bends towards the direction of the limiting column because the outlets of the purse string nail holes are smaller. After the limit hole 64 and the limit bump 65 are matched, the elastic buckle structure cannot retract into the purse-string nail hole, so that the purse-string nail cannot be extruded into the purse-string nail hole by tissues.
The purse string suture member 4 is provided with a purse string nail hole, and the anastomosis member 3 is provided with an anastomosis nail hole; the distance between any two adjacent purse-string nail holes is 4.2-4.4mm; the distance between any two adjacent anastomotic nail holes is 3.9-4.1mm. The total length of the anastomosis nail is set as L1, the total length of the pouch nail is set as L2, as shown in fig. 4, wherein a is the distance between two anastomosis nail holes, b is the distance between two pouch nail holes, various anastomosis mechanisms with different L1/L2 specifications, such as 45mm anastomosis mechanisms, 60mm anastomosis mechanisms, 75mm anastomosis mechanisms, 90mm anastomosis mechanisms and the like, are combined and matched by different n1 and n2, and the data collected by multiple test verification and pressure resistance show that the combined anastomosis mechanism has the best pressure resistance/anastomosis/pouch effect when a=4mm and b=4. 3mm.
