Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an adjustable anorectal stapler. Background Technology

[0002] An anorectal stapler is a surgical instrument specifically designed for anastomosing the intestines, commonly used to treat hemorrhoids and other anorectal diseases. Below is an introduction to anorectal staplers: Anorectal staplers come in various types, the most common being the hemorrhoid stapler, also known as the PPH stapler. It is primarily used to treat hemorrhoids and other anorectal diseases by removing and anastomosing prolapsed rectum, hemorrhoids, and other tissues to achieve the therapeutic goal. Anorectal staplers are surgical instruments specifically designed for anastomosing the intestines, commonly used to treat hemorrhoids and other anorectal diseases. Anorectal staplers come in various types, the most common being the hemorrhoid stapler, also known as the PPH stapler. It is primarily used to treat hemorrhoids and other anorectal diseases by removing and anastomosing prolapsed rectum, hemorrhoids, and other tissues to achieve the therapeutic goal.

[0003] Existing technology CN219000415U describes an adjustable anorectal stapler. This device incorporates a stabilizing mechanism. The suction tube is connected to a conduit via a connector. A spring is installed at one end of the conduit to prevent rebound. Pressing the handle drives a pusher block to push a transmission rod. A rotating handle is located on the outer wall of the pusher block. This design solves the problem that traditional staplers, which rely on a pressing handle, lack a stabilizing device to fix the number and intensity of handle presses within a certain time, leading to inconvenience for doctors and affecting surgical outcomes. A rotating switch drives the connecting cylinder and inner cylinder to achieve overall adjustment of the stapler. A sliding rod is inserted into the transmission rod; moving the sliding rod adjusts the position, and rotating the nut secures the connection. This design facilitates operation and solves the problem of only being able to adjust individual parts without adjusting their overall position.

The connecting threaded sleeve 201 can be used to connect the threaded rod 202 and the threaded sleeve rod 203, which increases the installation stability and also improves the convenience of disassembly.

[0031] The working process of this utility model is as follows: When the adjustable anorectal stapler designed in this scheme is in operation, the anorectal stapler is inserted into the patient's body. After reaching the appropriate position, the cutting range of the blade 310 can be adjusted according to the extent of the patient's excess tissue growth. The second motor 302 drives the second rotating rod 303 to rotate. The rotation of 303 causes the adjusting rod 307 to move within the limiting groove 305. At the same time, the sliding rod 309 slides within the sliding groove 308, which in turn causes the blade 310 to expand outward or contract inward, thereby adjusting the cutting area of ​​the blade 310. Then, the first motor 204 drives the first rotating rod 205 to drive the entire blade adjusting assembly 3, which makes the blade 310 rotate, thereby cutting the patient's excess skin and flesh tissue.
