Description

Novel measurement type seal wire

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel measuring guide wire.

Background

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a technique in which a duodenoscope is inserted into the descending part of the duodenum to find the duodenal papilla, a contrast catheter is inserted into the opening of the papilla from a biopsy channel, and a contrast medium is injected into the opening of the duodenal papilla to perform x-ray radiography to display the cholangiopancreatography. Because ERCP does not need to be operated, the trauma is small, the operation time is short, the complication is less than that of the surgical operation, the hospitalization time is greatly shortened, and the ERCP is popular with patients. ERCP has achieved great clinical results in a few decades, and has become an important treatment means for pancreatic and biliary diseases today.

Nipple intubation: the simplest is where ERCP dream starts, and the most complicated operation: the key to success and failure of ERCP is the technical difficulty, which affects the incidence of complications. After successful intubation, the judgment of the narrow length of the biliary tract and the grasping of the length of the guide wire enter are related to the completion time of the whole operation, the selection of instruments and the effectiveness of instrument exchange.

The appearance of the prior guide wire is essentially equivalent, the head end is a hydrophilic soft head with the length of 5-8 CM, the rear section is two colors of crossed zebra stripes, the ERCP guide wire generally enters the space with the length of 10-20CM, the guide wire part can be observed to be almost the zebra stripes by a duodenoscope, the entering length can not be judged under the endoscope, and an X-ray machine is required to be opened for many times to see the entering length of the guide wire in clinic, thereby bringing unnecessary ray injury to patients and operators.

SUMMERY OF THE UTILITY MODEL

To overcome the above-described deficiencies of the prior art, embodiments of the present invention provide a novel gauge guidewire that is capable of determining the entry length under the scope.

In order to achieve the purpose, the utility model provides the following technical scheme: a novel measuring guide wire is provided with a zebra-shaped guide wire; the end part of the guide wire is provided with an elastic hydrophilic head, the surface of the guide wire is provided with a drag rod marking line, and the marking lines are distributed at a certain distance and used for calculating the entering length of the guide wire.

The more optimized scheme is a novel measurement type seal wire, seal wire head end inner core cladding has spiral coil for deepen the pyrocondensation compactness of seal wire inner core and outer tube.

The more optimized scheme is the novel measuring guide wire, the marking line is provided with various color combination coatings, and the distance between the coating lines of various colors can be measured.

The more optimized scheme is the novel measuring guide wire, the marking wire is formed by coating a metal wire winding layer on the guide wire, and the metal wire winding layer can be displayed under X-rays.

The more optimized scheme is that the novel measurement type guide wire is characterized in that the head of the hydrophilic head is connected with a high-elastic nickel-titanium alloy wire.

The utility model has the technical effects and advantages that:

1. the length of the guide wire entering can be judged according to the clinical requirement through the distance of the marker under the lens, and the X-ray machine does not need to be repeatedly switched on and off to see through the entering length of the guide wire, so that unnecessary ray injury to a patient and a doctor is avoided.

2. Meanwhile, the high elasticity of the hydrophilic head can avoid the damage to a patient in the threading process, improve the success efficiency of threading and avoid repeated threading.

Drawings

Fig. 1 is a schematic view of the overall structure of the present invention.

The reference signs are: 1. a guide wire; 2. a hydrophilic head; 3. marking a line; 4. a helical coil; 5. nickel-titanium alloy wire;

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

As shown in fig. 1, the utility model provides a novel measuring guide wire, which is a guide wire 1 with zebra stripes; the end part of the guide wire 1 is provided with an elastic hydrophilic head 2, the surface of the guide wire 1 is provided with a drag rod marking line 3, and the marking lines 3 are distributed at a certain distance and used for calculating the entering length of the guide wire 1.

The inner core at the head end of the guide wire 1 is coated with a spiral coil 4 for deepening the heat shrinkage tightness of the guide wire inner core and the outer tube.

The marking lines 3 are combined coatings of various colors, and the distance between the coating lines of various colors can be measured.

The marking line 3 is formed by coating a metal wire winding layer on the guide wire 1, and the metal wire winding layer can be displayed under X-rays.

The head of the hydrophilic head 2 is connected with a high-elastic nickel-titanium alloy wire 5.

The working principle of the utility model is as follows: the hydrophilic head 2 carries the guide wire 1 to penetrate through the body of the patient, and the distance of the guide wire 1 is calculated under the inner lens.

The points to be finally explained are: first, in the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounted," "connected," and "connected" should be understood broadly, and may be a mechanical connection or an electrical connection, or a communication between two elements, and may be a direct connection, and "upper," "lower," "left," and "right" are only used to indicate a relative positional relationship, and when the absolute position of the object to be described is changed, the relative positional relationship may be changed; in the drawings of the disclosed embodiments of the utility model, only the structures related to the disclosed embodiments are referred to, other structures can refer to common designs, and the same embodiment and different embodiments of the utility model can be combined with each other without conflict; the above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
