Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument technical field especially, it relates to a damping's guide wire inserter. BACKGROUND

[0002] As a commonly used medical instrument in endoluminal intervention surgery, the guide wire plays a crucial role in guiding the interventional instrument to the target lesion site. The commonly used guide wire mainly includes straight guide wire and J-type guide wire. Among them, the J-type guide wire is difficult to make the head end smoothly enter the dilator, metal needle and other instruments for directional guidance during the operation, which brings certain difficulty to the operation.

[0003] The traditional guide wire inserter is usually conical in design, and only has a certain damping effect on the guide wire at the tip. However, when the guide wire needs to be inserted into other medical instruments, the guide wire must be withdrawn from the tip first. In this case, the damping support between the guide wire and the inserter is lost, which can easily cause the guide wire to fall off, which not only may cause contamination, but also has safety risks. In addition, the process of reconfiguring the guide wire into the inserter will prolong the operation time and affect the operation efficiency.

[0004] Based on this, in order to solve the above technical defects, a guide wire inserter with damping is proposed. UTILITY MODEL CONTENTS

[0005] In order to overcome the shortcomings of the traditional guide wire inserter that the guide wire is easily caused to fall off when being pushed out of the tip, the technical problem to be solved is to provide a guide wire inserter with damping.

[0006] Technical scheme: a guide wire inserter with damping, comprising a guide wire inserter body and a damping block, a conical guide wire passage opening is formed in the guide wire inserter body, a tip opening is formed on the left side of the guide wire inserter body, and a tail end opening is formed on the right side, the guide wire passage opening is communicated with the tip opening and the tail end opening of the guide wire inserter body, a damping block is integrally formed on the position close to the tail end opening inside the guide wire inserter body, and the position where the damping block is obliquely raised forms a connecting port with the guide wire inserter body to provide a movable space for the damping block.

[0007] Further, the damping block is made of elastic material, which can generate friction when the guide wire is inserted or withdrawn.

[0008] Further, the conical guide wire passage opening of the guide wire inserter body further comprises at least one intermediate transition section, which helps the guide wire to smoothly pass through the entire inserter from thick to thin.

[0009] Further, the guide wire inserter body is conical in shape, and the tip opening has damping effect on the guide wire.

[0010] Further, the outer wall of the guide wire inserter body is provided with anti-skid lines.

[0011] Further, the anti-skid lines are in a concave-convex structure, which can be longitudinal, transverse or patterned to increase the friction between the hand and the guide wire inserter body.

[0012] Compared with the prior art, the guide wire inserter has the following advantages: 1. The damping block is arranged at the position close to the tail end opening of the guide wire passage opening, and when the guide wire exits the tip opening of the guide wire inserter body, the damping block can automatically clamp the guide wire to generate a certain resistance to the guide wire, thereby avoiding the guide wire from falling off and effectively improving the stability and safety during the guide wire insertion process;

[0013] 2. During the guide wire insertion and movement process, the damping block can provide continuous resistance control, avoiding accidental injuries caused by rapid movement of the guide wire, so that the doctor can more accurately control the position of the guide wire, reducing the risk of surgery;

[0014] 3. The design of the damping block not only provides the necessary resistance, but also enables the doctor to easily manually adjust the position of the guide wire, ensuring the stability of the guide wire during the advancement process, and not hindering the doctor from adjusting the position of the guide wire as needed.
