[0027] Through the above scheme, the round head and the second clamping ring telescopic tube can be driven to extend and retract by installing the connecting rod and the telescopic tube, and the connection between the clamping block and the clamping groove can prevent the connecting rod from falling off when being driven to extend and retract.

[0028] In this embodiment, preferably, a round head 206 is fixedly mounted on the front end of the connecting rod 204 , a second clamping ring 301 is movably mounted on the outer side of the round head 206 , and a matching groove 302 is formed on the front end of the second clamping ring 301 .

[0029] According to the above scheme, the anastomotic staple can be inserted and bent through the anastomotic groove, and the rectum is sutured after the anastomotic staple is bent, and the second clamping ring and the first clamping ring are closely fitted to clamp the suture.

[0030] In this embodiment, preferably, the control mechanism 102 includes a control tube 303 , the front end of which is fixedly provided with an insertion tube 103 , the front side of which is fixedly provided with a clamping plate 305 , the front end of which is fixedly provided with a cutter 201 .

[0031] Through the above scheme, the manipulation tube can be used for grasping, the insertion tube can be used for inserting into the patient's rectum, and the cutter can be installed through the clamping plate, so that the cutter can be kept stable during cutting.

[0032] In this embodiment, preferably, a spring 501 is fixedly installed at the front end of the clamping plate 305 , a first rotating block 306 is fixedly installed at the rear end of the clamping plate 305 , and a tilting rod 401 is movably installed in the first rotating block 306 .

[0033] Through the above scheme, the cutter can rebound quickly after cutting through the spring, and the inclined push rod can be rotated through the first rotating block. When the inclined push rod rotates, it can push the clamping plate to extend forward so that the cutter can extend forward for cutting.

[0034] In this embodiment, preferably, the inclined push rod 401 is fixedly installed in the middle of the top of the handle 402, the front end of the handle 402 is movably installed in the second rotating block 403, and the second rotating block 403 is fixedly installed on the front side of the bottom end of the control tube 303.

[0035] According to the above scheme, the handle is rotated in the second rotating block, so that the inclined ejector rod can be driven to eject the clamping plate.

[0036] In this embodiment, preferably, an adjusting cylinder 404 is movably installed at the rear end of the control cylinder 303, a screw cylinder 405 is fixedly installed at the front end of the adjusting cylinder 404, the screw cylinder 405 is movably installed at the rear side of the control cylinder 303, a screw rod 406 is movably installed in the control cylinder 303, and a telescopic tube 202 is fixedly installed at the front end of the screw rod 406.

[0037] Through the above scheme, the screw barrel can be adjusted through the adjusting barrel, and the screw barrel can be rotated outside the screw rod, so that the screw rod can be screwed and extended and the telescopic tube can be driven to extend and extend.

[0038] When using the anti-leakage device for rectal anastomosis after surgery of this embodiment, the user puts the round head 206 into one end of the rectum, and then uses sutures to tighten the rectal opening and let the connecting rod 204 leak out. At this time, the user inserts the insertion tube 103 into the rectum through the patient's anus, and then rotates the adjustment cylinder 404 to make the screw cylinder 405 rotate outside the screw rod 406. As a result, the telescopic tube 202 is screwed out from the inside of the cutter 201. At this time, the rectal opening at one end of the anus is tightened with a suture thread to leak the telescopic tube 202. At the same time, the user inserts the connecting rod 204 into the telescopic tube 202 and clamps it with the clamping groove 203 through the clamping block 205 to keep it fixed. Then the user twists the adjusting cylinder 404 again to make the telescopic tube 202 drive the round head 206 to retract. During the retraction, the two ends of the rectum are driven to fit together. At the same time, the anastomotic staple 106 penetrates the rectum and is inserted into the anastomotic groove 302 and bends. When the anastomotic staple 106 bends, it is similar to the bending of a stapler, so that the rectal opening is sutured and fixed. At this time, the user presses The pinch handle 402 is moved, so that the pinch handle 402 rotates through the second rotating block 403. The rotation of the pinch handle 402 causes the inclined push rod 401 to rise. When rising, the inclined push rod 401 rotates in the first rotating block 306, so that the push rod pushes the clamping plate 305 forward, thereby pushing the cutter 201 forward to cut the rectal suture and the connection between the second clamping ring 301 and the round head 206. After cutting, the user takes out the insertion tube 103 through the control cylinder 303 and drives the round head 206 to be taken out. At this time, due to the bending clamping of the staples 106 and the anastomotic groove 302, the first clamping ring 105 and the second clamping ring 301 clamp the rectal suture, thereby achieving a leak-proof effect.
