The present invention relates to the technical field of tissue suturing. Disclosed is a tissue closure device. The tissue closure device includes: a tube body, a driving member, and a needle operating member. The driving member is provided in the tube body and capable of moving between a stabilizing member triggering position in which a stabilizing member at a distal end of the tissue closure device is driven to expand and an initial stabilizing member position in which the stabilizing member is driven to close up. The needle operating member is provided in the tube body and capable of moving between a needle triggering position in which a suture needle in the tube body is driven to extend out of the tube body and an initial needle position in which the suture needle is allowed to retract into the tube body. When in the initial needle position, the needle operating member allows the driving member to switch between the initial stabilizing member position and the stabilizing member triggering position, and when in the needle triggering position, the needle operating member stops the driving member from returning from the stabilizing member triggering position to the initial stabilizing member position. When the suture needle does not retract into the tube body, the stabilizing member remains in the expanded position, thereby preventing undesirable closing-up of the stabilizing member, which would have otherwise deformed the suture needle and thus damaged other surrounding organs, if any, thereby improving safety.

The present invention relates to the technical field of tissue closure. Disclosed is a tissue closure device. The tissue closure device includes a tube body. The tube body includes two half tube portions that can be combined. A half suture needle channel groove is formed on a combining surface of each half tube portion, and each suture needle channel groove includes a curved groove segment. When the two half tube portions combine to form the tube body, the half suture needle channel groove on one of the half tube portions and the half suture needle channel groove on the other half tube portion combine to form a suture needle channel. Therefore, a desired shape of the suture needle channel can be easily formed. During assembly, a suture needle and a needle operating member are placed on one of the half tube portions, and then the other half tube portion is combined with and connected to the half tube portion, so that the suture needle is accommodated in the suture needle channel and the needle operating member is located in the tube body, thereby increasing the ease of assembling the tissue closure device. Guiding the suture needle through the suture needle channel enables the suture needle to move stably and prevents a shift in puncture position, thereby improving the healing effect of suturing a wound.
