Embodiment Construction

[0035] Embodiments will be described in detail below, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following examples are not intended to represent all implementations consistent with this application. are merely exemplary of systems and methods consistent with some aspects of the present application as recited in the claims.

[0036] It should be noted that, in the technical solution provided in this application, for the convenience of description, the end where the entire device is placed in the human body is called the distal end, and this end is mainly used to perform surgical actions on the tissue; the end located outside the body is called the proximal end , this end is mainly used for the operation of the operator. Unless otherwise specified in this appl...

Abstract

The invention provides a chute type multi-arm clamp, which comprises: a handle, a catheter, a clamping portion, a spring tube and a control line. In practical applications, an operator applies axial thrust and tension to the handle to drive the control line to achieve opening/closing and locking of the clamping portion. Moreover, a side clamp arm and a clamp seat in the clamping portion can be easily separated from the catheter or the spring tube to stay in the human body to achieve the function of hemostasis and tissue suture. The chute type multi-arm clamp can achieve the shortest length ofthe instrument retained in the human body by the cooperation of the side clip arm and the clip holder, the movable chute structure on the side clamp arm can realize accurate and repeatable opening andclosing, and can simplify the operation and improve the success rate.

Description

technical field [0001] The present application relates to the technical field of medical devices, and in particular, to a chute type multi-arm clamp. Background technique [0002] Endoscopic EMR (endoscopic mucosal resection) and ESD (endoscopic mucosal dissection) have a high cure rate for early cancer and are widely used in clinical practice. For endoscopic mucosal resection and dissection, postoperative wound closure is required using forceps or clips appropriate to the endoscopic environment. [0003] In practical applications, the operating space under the endoscope is small, and the working channel through the endoscope is small. In the physiological bending of the human body, for the bleeding site of the larger wound, the opening width of the existing forceps or clip products after reaching the lesion site is limited. Usually at 11mm, for the super-large wound of 50mm, the whole wound cannot be covered. Therefore, in order to realize the treatment of super large wou...
