Problems solved by technology

However, due to the differences in the individual structure of the human body, the pre-plastic catheter cannot fully adapt to all clinical needs. Once the inserted catheter does not conform to the patient's physiological structure, it needs to be withdrawn and reinserted with a new catheter, which increases the operation time and may cause harm to the patient. harm

Embodiment Construction

[0044] The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0045] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0046] In order to describe the structure of the adjustable catheter more clearly, the terms "proximal end" and "distal end" are defined here as relative positions, which are commonly used terms in the field of interventional medicine. Specifically, "distal end" means the end away from the operator during the surgical operation, and "near end" means the end close to the operator during the surgical operation.

Abstract

The invention discloses a control handle and an adjustable bending catheter. The control handle is used for controlling rotation of a catheter body connected with the control handle and controlling bending of at least one adjustable bending section located at the far end of the catheter body, and the control handle comprises a fixing part, a steering control part and a rotary bending adjusting part. The fixing part is used for installing an adaptive interface to connect external equipment; the steering control part is rotatably connected with the fixing part, and the steering control part is used for fixing the catheter body connected with the control handle and driving the catheter body to rotate relative to the fixing part; and the rotary bending adjusting part comprises a rotary control assembly and a driving adjusting assembly, the driving adjusting assembly is arranged in the steering control part and connected with the adjustable bending section, and the rotary control assembly is rotatably arranged on the steering control part and can control the driving adjusting assembly to move so as to change the bending degree of the adjustable bending section. According to the control handle, in an interventional operation, the bending and rotating functions of the far end of the catheter body can be achieved by operating the control handle outside the body.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a control handle and a bending catheter. Background technique [0002] The catheter is used in human septal puncture, cardiovascular intervention, peripheral vascular intervention, and other human organ cavity intervention or minimally invasive treatment, cardiac atrial septal puncture, renal artery ablation, heart valve repair, tumor interventional embolization, etc. An indispensable auxiliary tool in surgery that requires precise positioning, it is usually necessary to use a pre-plastic catheter to pre-establish a channel from the outside of the body to the target position to provide a channel for subsequent guide wires or other instruments to enter the diagnosis and treatment. However, due to the differences in the individual structure of the human body, the pre-plastic catheter cannot fully adapt to all clinical needs. Once the inserted catheter does not conform t...
