Adjustable bent catheter suitable to be operated by left hands

Abstract

The invention discloses an adjustable bent catheter suitable to be operated by left hands. The adjustable bent catheter comprises a catheter body, a handle assembly and a Luer taper. The handle assembly comprises a gripping handle, a sliding mechanism and a sliding control mechanism; a proximal end of the catheter body penetrates a cavity of the gripping handle and is connected with the Luer taper; the sliding mechanism comprises a sliding base and a sliding component, the sliding base is arranged in the cavity of the gripping handle or the sliding control mechanism, and the sliding component is fittingly arranged on the sliding base, can axially slide along the gripping handle and is fixedly connected with a traction wire; the sliding control mechanism comprises connectors and a driving adjusting component, the connectors are connected with the sliding component, the driving adjusting component is connected with the connectors and is arranged at a proximal end of the gripping handle capable of being conveniently operated by fingers of the left hands, and the position of the sliding component can be adjusted by the driving adjusting component. The adjustable bent catheter has the advantages that the handle can be controlled by the left hands, guide wires can be controlled by right hands, accordingly the efficiency can be improved when the guide wires are explored into target blood vessels, operation steps can be simplified, super-selection can be conveniently and quickly carried out on the target blood vessels by operators, the surgical operation time can be shortened, and X-ray radiation hazards on patients can be reduced.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an adjustable curved catheter, in particular to an adjustable curved catheter suitable for left-handed operation. Background technique [0002] Because interventional surgery has less damage to the human body and can effectively shorten the operation time, it is a medical technology that has been rapidly emerging and promoted in recent years. As an auxiliary device for interventional surgery, the catheter mainly provides a channel for the guide wire. Position the catheter tip toward the entrance of the target vessel, and guide the guidewire into the target vessel. According to the different intended uses of the catheter, the distal end of the catheter is preformed into different curved shapes to adapt to the anatomical shape of the specific lesion, so that the distal end of the catheter can be aligned with the lesion in the human body, such as renal artery catheter, radial ...

AI Technical Summary

Problems solved by technology

However, the adjustable curved catheter of the above-mentioned prior art is only suitable for right-handed operation, so it does not conform to the operating habits of left-handed catheter and right-handed guide wire, and it is necessary to repeatedly adjust the angle and direction of rotation of the catheter during the operation. The guide wire should be pushed in both angle and direction, and judge whether the mouth end of the catheter is pointing to the branch blood vessel by the direction of the guide wire advance

If the bending catheter is only suitable for right-handed operation, you need to use your right hand to adjust each angle and direction, and then use your right hand to push the guide wire to observe the direction of the guide wire, which takes a long time to operate; or cross your hands, However, this does not conform to the operating habits and may bring greater hidden dangers.
