A hemostatic and suturing conjoined dual-clamp capable of passing through a channel of a digestive endoscope and an operation method, said dual-clamp comprising a handle (26), a clamping assembly (10) and a driving assembly (20). The clamping assembly (10) comprises a clamping holder (12) and two clamping portions, the two clamping portions being provided around two sides of the clamping holder (12) and being rotatably connected to the clamping holder (12). The driving assembly (20) is able to drive the two clamping portions to open and close relative to the clamping holder (12) respectively, and the driving assembly (20) is detachably connected to the clamping assembly (10). A hemostatic and suturing conjoined dual-clamp capable of passing through a channel of a digestive endoscope and an operation method. Two clamping arms (11) of said dual-clamp are able to individually open, clamp and close, have a function of double-sided clamping and closing a large defective wound, and are able to be conveniently separated from the driving assembly (20), overcoming the defect that conventional hemostatic clamps can only perform one-sided clamping, thereby it is difficult to treat defective wounds that are large or in difficult operating sites.L'invention concerne une pince double conjointe hémostatique et de suture apte à passer à travers un canal d'un endoscope digestif et un procédé de fonctionnement, ladite pince double comprenant une poignée (26), un ensemble serrage (10) et un ensemble entraînement (20). L'ensemble serrage (10) comprend un support de serrage (12) et deux parties serrage, les deux parties serrage étant disposées autour de deux côtés du support de serrage (12) et étant reliées de manière rotative au support de serrage (12). L'ensemble entraînement (20) peut entraîner les deux parties serrage à s'ouvrir et se fermer par rapport au support de serrage (12) respectivement, et l'ensemble entraînement (20) est relié de façon détachable à l'ensemble serrage (10).
