Description

Double-end measurable quantity seal wire

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a double-end measurable quantity seal 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. With the advancement of science and technology and the development of ERCP surgery, ERCP is increasingly acknowledged and popularized in various social circles as a minimally invasive surgery, and a consumable material used as a guiding instrument is required to be used during the ERCP surgery: the guide wire plays an important role in the process of operation, and if the guide wire smoothly enters the bile duct, the operation can be said to have been half successful. The success or failure of the ERCP operation is directly influenced by the good performance of the guide wire, in addition, some difficult insertion tubes are touched in some operation processes, the guide wire easily enters the pancreatic duct, in order to improve the success rate of the operation, some medical care operators use a double guide wire system, the operation is to take another guide wire to insert a bile duct under the condition that one guide wire enters the pancreatic duct, so that the further operation is carried out, the length of the operated part is also needed to be known, such as the narrow part, the guide wire is inserted into the length of the bile duct part, and the like, so that the operation requirements and the operation time of the medical care operators are greatly improved, and in addition, the operation cost of patients is also increased.

SUMMERY OF THE UTILITY MODEL

To above demand, the utility model provides a double-end measurable quantity seal wire reduces medical personnel's the operation degree of difficulty, reduces operating time and patient's operation expense.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a double-end measurable quantity seal wire, includes the dabber, the dabber main part is equipped with the coating outward, dabber one end cover has straight head development sleeve pipe, and the other end is the bending structure, and the cover has elbow development sleeve pipe on it, and straight head development sleeve pipe and elbow development sleeve pipe terminal surface are the arc surface, and the side is smooth transition with the coating layer surface. One end of each guide wire is a straight soft head, the other end of each guide wire is an elbow soft head, and one guide wire is used as two guide wires, wherein the elbow soft head has the functions of easily entering narrow parts and selecting left and right hepatic ducts in an excess mode.

Preferably, the mandrel is a nitinol shaft.

Preferably, the diameter of the mandrel at both ends is smaller than the diameter of the central portion.

Preferably, scale marks are respectively arranged on two sides of the surface of the coating layer and used for measuring the length.

Preferably, the coating layer is a teflon coating layer, so that the controllability is improved, and a low friction coefficient is obtained.

Preferably, the included angle α between the axis of the mandrel and the axis of the tail end of the elbow developing sleeve ranges from 100 degrees to 135 degrees.

Preferably, the straight developing sleeve and the elbow developing sleeve are made of polyurethane.

Preferably, the surfaces of the straight developing sleeve and the elbow developing sleeve are provided with hydrophilic coatings, so that the friction force between the wire guide head and other instruments can be reduced when the developing sleeve is used.

The utility model has the advantages that: can realize the purpose that a seal wire uses as two seal wires, wherein one end is the soft head of straight head, and one end is the soft head of elbow in addition, and the soft head of elbow has the easy narrow position of entering to hepatic duct and length measurement's function about the super selection, in addition, reduce medical personnel's the operation degree of difficulty, reduce operating time and patient's operation expense.
