Document Type and Number:
WIPO Patent Application WO/2020/228841
Kind Code:
A1
Abstract:
An endoscope channel suturing forceps, comprising a housing (110), a clamping core (100), two clamping parts (120) and two control assemblies (200). First slide slots (111) are formed on the housing (110); second slide slots (121) are formed on the clamping parts (120), and each of the second slide slots (121) comprises a guide portion (1211) and a limiting portion (1212). The two control assemblies (200) are respectively used for independently controlling the two clamping parts (120) to open or close relative to the clamping core (100). The control assemblies (200) each comprise a slide block (211) and a control element (212); the slide blocks (211) are arranged in the second slide slots (121); once the clamping parts (120) are closed relative to the clamping core (100), the slide blocks (211) fasten into the limiting portions (1212); the control elements (212) are connected to the slide blocks (211), and a portion of each of the control elements (212) is positioned in the respective first slide slot (111). In the endoscope channel suturing forceps, the two control assemblies (200) may respectively control two clamping parts (120) to independently open or close relative to the clamping core (100). The first slide slots (111) guide and fasten the control elements (212) in place, ensuring the control elements (212) move in a stable manner along the fastening direction, thereby preventing slippage of the control elements (212) and ensuring reliable utilization of the product.
