Description

Technical Field

[0001] The utility model relates to the technical field of anastomotic suturing, in particular to an intrarectal suturing device. Background Art

[0002] The anastomosis is the junction between two tissues during surgery. During or after the hemorrhoidectomy (PPH) or selective hemorrhoidectomy (TST) surgery, an intrarectal stapler is required to suture the anastomosis.

[0003] Existing anorectal surgical staplers all achieve the purpose of suturing by rotating the stapler as a whole to drive the suturing needle to rotate. Since the anal canal is narrow and long, there is not enough space for the stapler to rotate 180° longitudinally, whether it is retracted by a retractor or exposed by an anoscope, so it is difficult to achieve longitudinal suturing of the rectal wound, and only transverse suturing is possible; when the rectal wound is large or multiple wounds are sutured transversely, transverse suturing may cause rectal stenosis.

The main body of the suture needle 1 is set to an arc structure. When in use, the suture thread is fixed on the suture needle 1 through the wire groove 14. One hand holds the handle 7, and the other hand rotates the driving wheel 6 to drive the second rotating shaft 10 to rotate, and drives the chain belt 11 to rotate through the second sprocket 4, and then drives the first sprocket 2 to drive the first rotating shaft 9 to rotate, and drives the suture needle 1 to rotate through the limit ring 12 and the pressure cover 13 to suture the patient. Through the cooperation of the set suture assembly and the driving assembly, the main rod 3 of the suturer can be rotated without rotating the main rod 3 of the suturer, and the utility model can easily realize the rotation of the suture needle 1 at any angle on the longitudinal section in a narrow space to achieve longitudinal suturing; the handle 7 offset to the midline does not block the field of view; the structure is simple, the operation is convenient, and it is economical and practical.

[0025] Furthermore, the fixing assembly includes two fixing rods 5 fixedly installed on the rear side of a main rod 3, one end of the two fixing rods 5 is fixedly connected to the same handle 7, and the fixing rods 5 are used to connect the handle 7 and the main rod 3 to facilitate the holding and use of the suturer.
