Description
Technical Field
The utility model relates to a visual nose bile duct oronasal cavity converter.
Background
With the development of the digestive endoscopy, the advanced development of Endoscopic Retrograde Cholangiopancreatography (ERCP) is achieved, wherein 80% of patients in the ERCP have an important role in alleviating the biliary pressure, eliminating obstructive jaundice, controlling inflammation and improving the general condition of the patient by Endoscopic nasobiliary drainage (ENBD), which not only can fully drain bile, but also can wash bile ducts and repeatedly perform cholangiography, and is a biliary drainage mode with simple operation, safety and effectiveness. The nasal bile duct oral-nasal cavity switching in the ENBD process is one of the most important links. At present, the most common method for realizing the oral-nasal cavity conversion of the nasal bile duct is a guide wire sleeving method at home and abroad, which is widely applied to the ERCP diagnosis and treatment process, but still has the defects that the method mainly comprises the following two aspects: firstly, the one-time success rate is low in the conversion process, the repeated insertion of guide wires for many times has obvious stimulation to the pharynx of a patient, the nausea is aggravated, the patient can not cooperate, and even a patient bites; secondly, whether the silica gel hose is successfully inserted into a ring formed by the guide wire or not can not be predicted in the conversion process, so that the silica gel hose needs to be repeatedly inserted into the nasal cavity, the distal end can be separated out, the nasal bile duct can be broken through repeated operation, and even an anesthesia accident can occur.
SUMMERY OF THE UTILITY MODEL
The utility model provides a visual nose bile duct oronasal cavity converter, simple structure, convenient to use realizes the high-efficient smooth completion of nose bile duct oronasal cavity conversion, better application in the nose bile duct drainage art under the endoscope.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a visual nose bile duct oronasal cavity converter which characterized in that: power supply unit's top and light emitting device's bottom integrated into one piece and electricity are connected, and the bottom cover of handle is established and is fixed in power supply unit's top, the handle with be 30 degrees contained angles on the power supply unit horizontal plane, avoid sheltering from the sight, the handle bilateral symmetry sets up the slipmat, the top of handle can be dismantled with the bottom of bending pole and be connected, the top inboard of bending pole sets up the dogtooth, supplies to increase frictional force.
The visual nose bile duct oronasal cavity converter, wherein: the side wall of the power supply device is provided with a power switch for controlling the on-off of the light-emitting device, and the bottom end of the power supply device is provided with a USB interface for charging.
The visual nose bile duct oronasal cavity converter, wherein: the curved rod is arc-shaped and is consistent with the radian in the oral cavity.
The utility model has the advantages that: this equipment is easy and simple to handle, and the security is high, and the oronasal cavity conversion of nose bile duct does not need the zebra seal wire in ENBD, only needs this converter once only to accomplish, and the success rate is high, avoids amazing pharynx back wall repeatedly, and the converter replaces the finger to avoid the art person to sting, makes things convenient for medical personnel to operate. The expected effect is good, the compliance of the patient is good, the traditional method of taking the nasal bile duct blindly can be almost replaced, especially for the anaesthetized patient, the tongue root can be avoided easily, the conversion success rate of the oral cavity and the nasal cavity is greatly improved, and the anaesthesia accident is reduced.

Detailed Description
As shown in fig. 1 to 5, the visible nose bile duct oronasal cavity converter is characterized in that: the top of power supply unit 1 is connected with illuminator 2's bottom integrated into one piece and electricity, set up switch 5 on power supply unit 1's the lateral wall, supply control illuminator 2 opens and close, power supply unit 1's bottom sets up USB interface 8, through USB interface 8 can give power supply unit 1 charges, and the bottom cover of handle 3 is established and is fixed in power supply unit 1's top, handle 3 with be 30 degrees contained angles on the power supply unit 1 horizontal plane, avoid sheltering from the sight, the 3 bilateral symmetry of handle sets up slipmat 6, the top of handle 3 can be dismantled with the bottom of curved pole 4 and be connected, the top inboard of curved pole 4 sets up dogtooth 7, supplies the increasing friction power, curved pole 4 is arc to be unanimous with the oral cavity radian.
In the embodiment, medical personnel firstly insert the silica gel hose to the pharyngeal backwall through the nasal cavity, press the power switch 5, turn on the light source of the light-emitting device 2, hold the handle 3, at the moment, place the thumb and the forefinger on the non-slip mat 6, gently put the bent rod 4 into the oral cavity, observe the oral cavity through the light-emitting device 2, form a 30-degree included angle between the handle 3 and the horizontal plane of the power device 1, without influencing the operation sight, clamp the silica gel hose inserted to the pharyngeal backwall by using the bent rod 4 under the visible condition of illumination, and slowly pull out the oral cavity, prevent the convex teeth 7 arranged at the inner side of the bottom end of the bent rod 4 from slipping when clamping and pulling the silica gel hose, pull out the oral cavity, butt joint the silica gel hose and the tail end of the nasal bile duct to form a pipeline, and lightly pull out the silica gel hose out of the nasal cavity, and taking out the nasobiliary duct until the nasobiliary duct of the laryngeal part is straightened, and completing the oral-nasal cavity conversion of the nasobiliary duct.
The utility model has the advantages that:
this equipment is easy and simple to handle, and the security is high, and the oronasal cavity conversion of nose bile duct does not need the zebra seal wire in ENBD, only needs this converter once only to accomplish, and the success rate is high, avoids amazing pharynx back wall repeatedly, and the converter replaces the finger to avoid the art person to sting, makes things convenient for medical personnel to operate. The expected effect is good, the compliance of the patient is good, the traditional method of taking the nasal bile duct blindly can be almost replaced, especially for the anaesthetized patient, the tongue root can be avoided easily, the conversion success rate of the oral cavity and the nasal cavity is greatly improved, and the anaesthesia accident is reduced.
