Operating handle of adjustable bending sheathing canal with identification and adjustable bending sheathing canal

Abstract

The invention discloses an operating handle of an adjustable bending sheathing canal with identification and the adjustable bending sheathing canal, the operating handle comprises an identification device, a knob, a wire fixing device, a first sliding block, a second sliding block, a rail shell and a supporting tube, the sliding blocks are driven to slide by rotating the knob, and then a traction wire is pulled to control the far end of a catheter to reach an expected bending shape. Due to the fact that the rotary knob is in threaded fit with the sliding block, the force needed for controlling the near-end handle can be reduced, a user can operate the handle in a more labor-saving mode, and the bending shape of the far end can be accurately adjusted. And the handle has a self-locking function, so that an operator can lock the bent shape at any position by operating the handle, and the bent shape can be fixed without other operations after the expected bent shape is achieved. The rotary knob rotates to drive the rotating mark to rotate relative to the bent mark, so that the bent state of the far end of the catheter can be visually known at the handle, the visual operation of the catheter is enhanced, the use difficulty of the catheter is reduced, and the radiation time of X rays in an operation is shortened.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an operating handle of an adjustable curved sheath with a mark and the adjustable curved sheath. Background technique [0002] Interventional therapy is a medical technology that introduces precision medical devices such as special catheters and guide wires into the human body under the guidance of medical imaging equipment to diagnose and treat lesions in the human body. As we all know, interventional surgery usually requires the use of interventional diagnostic sheaths (such as guiding catheters, delivery sheaths, guiding sheaths, etc.) Insert the device and wait until the patient's lesion. Since the sheath cannot be visualized after it enters the blood vessel of the human body, medical staff performing interventional operations generally need to send the distal end of the sheath to a predetermined position by operating the handle outside the body under the guidanc...

Problems solved by technology

[0011] The purpose of the present invention is to provide an adjustable curved sheath tube with a mark for the problems in the prior art that the operation of the handle is laborious, the curved shape cannot be locked at any position, and the direction of the curved shape at the distal end cannot be intuitively judged.
