Abstract

The application relates to a urinary guide wire, including the seal wire body, the one end of seal wire body sets up first soft head, the other end of seal wire body sets up the soft head of second, first soft head is the soft head of loach seal wire or mixes the soft head of seal wire, the soft head of second is the soft head of zebra seal wire. The urinary guide wire adopts a double-soft-head design, a first soft head is used when the urinary guide wire needs to be flexibly treated, a second soft head is used when rigid support is needed, and one guide wire can meet two requirements. Moreover, because both ends are soft heads, the condition that the ureter is damaged due to the insertion of a hard head can be reduced.

Description

Urinary guide wire

Technical Field

The present application relates to medical interventional devices, and more particularly, to a urinary guidewire.

Background

Urolithiasis is one of the most common diseases in urology surgery. In China, the incidence of urinary calculi is about 1% -5%, in southern areas is as high as 5% -10%, according to the situation of general investigation of Chinese population in 2010, the corrected prevalence of kidney calculi of Chinese adults is 5.8%, wherein the prevalence of male is 6.5%, and the prevalence of female is 5.1%. According to the estimation, about 6120 ten thousand adult kidney stone patients exist in China, wherein about 3470 thousands of men exist and about 2650 thousands of women exist. The data suggest that the patient base for treating the kidney stone by the operation is large, and more than 20000 cases are generated in Shenzhen region every year, and 200 ten thousand cases are generated in China every year.

Most urological procedures require a guide wire as a guide, such as ureteroscopy, percutaneous nephrolithotomy, and the like. Common guide wires are loach guide wires, zebra guide wires and hybrid guide wires. The loach guide wire consists of a nickel-titanium alloy core wire, an outer coating layer polyurethane material and a hydrophilic polymer, and the surface of the guide wire is smooth like the appearance of loaches under the activation of water. The zebra guide wire is formed by wrapping a layer of hydrophobic special bicolor PTFE (polytetrafluoroethylene) film outside a flexible nickel-titanium alloy core wire, has the appearance like zebra stripes, and is clearly distinguished under X-ray. The hybrid guidewire has hybrid properties, both on the core wire, which is typically a mixture of a nickel titanium inner core and 304 stainless steel wire wrap, and a hydrophilic coating on the tip and then a PTFE coating.

However, the guide wires are basically designed to be soft at one end and hard at the other end, so that the complex requirements in practical use cannot be well met, and the ureter is easily damaged by inserting the hard head by mistake.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the present application is to provide a urinary guidewire with a double soft-tip design, which addresses the above-mentioned drawbacks of the prior art.

The technical scheme adopted by the application for solving the technical problem is as follows: the utility model provides a urinary guide wire, includes the seal wire body, the one end of seal wire body sets up first soft head, the other end of seal wire body sets up the soft head of second, first soft head is the soft head of loach seal wire or mixes the soft head of seal wire, the soft head of second is the soft head of zebra seal wire.

In one embodiment of the urinary guidewire of the present application, the distal ends of the first and second soft tips are rounded tips.

In an embodiment of the urinary guidewire, the urinary guidewire is provided with a plurality of soft heads, and the soft heads are connected with the urinary guidewire body through the soft heads.

In one embodiment of the urinary guidewire of the present application, the scale markings include first scale markings spaced apart by 5cm and second scale markings spaced apart by 1 cm.

The urinary guide wire has the following beneficial effects: according to the utility model provides a uropoiesis seal wire adopts two soft head designs, and first soft head is the soft head of loach seal wire or mixes the soft head of seal wire, and the soft head of second is the soft head of zebra seal wire, uses first soft head when needs relatively flexible processing, uses the soft head of second when needing rigid support, and a seal wire can satisfy two kinds of demands. Moreover, because both ends are soft heads, the condition that the ureter is damaged due to the insertion of a hard head can be reduced.

Drawings

The present application will be further described with reference to the accompanying drawings and examples, in which:

FIG. 1 is a schematic view of a urinary guidewire according to one embodiment of the present application;

figure 2 is an enlarged view of a portion of a urinary guidewire according to another embodiment of the present application.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application. Also, the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

As shown in FIG. 1, a urinary guidewire 10 according to one embodiment of the present application includes a guidewire body 11, and a first soft tip 12 is provided at one end of the guidewire body 11 and a second soft tip 13 is provided at the other end of the guidewire body 11. In a specific implementation, the first soft head 12 can be a loach guide wire soft head or a mixed guide wire soft head, and the second soft head 13 can be a zebra guide wire soft head. The urinary guide wire 10 adopts a double-soft-head design, is smooth and soft, and is easy to put in, so that the wound is reduced. When a relatively flexible treatment is required, the first soft head 12 which is relatively more flexible is used, and when a rigid support is required, the zebra guide wire performance of the second soft head 13 is used, so that one guide wire can meet two requirements. As further shown in fig. 1, the end of the first soft head 12 is designed to be a round end 121, and the end of the second soft head 13 is also designed to be a round end 131, so that the head end is smooth and easy to be inserted, and the injury to the human body is avoided.

Referring further to the embodiment shown in fig. 2, the two ends of the guide wire body 11 are provided with scale marks 141, and the scale marks 141 are distributed along the length direction of the guide wire body 11 with the joint with the first soft tip 12 and the second soft tip 13 as the starting point, so as to facilitate the doctor to observe the insertion depth of the urinary guide wire 10 during operation. The scale marks 141 can be distributed as desired, for example, in fig. 2, the scale marks can include first scale marks 143 spaced by 5cm and second scale marks 142 spaced by 1cm, which is convenient for the doctor to observe.

According to the double-soft-head urinary guide wire introduced in the embodiment of the application, the operation risk can be reduced, and the safe operation can be realized. Under the premise of high rock formation and high hair all over the world, the design and the application have good application prospect, wide market range and certain economic and social values.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
