Description
Technical Field
The utility model relates to a digestive tract endoscope ultrasonic examination auxiliary balloon with a guide wire.
Background
Endoscopic Ultrasound (EUS) examination relies on the perfect combination of the endoscope, the ultrasound probe, the wall of the digestive tract and the ultrasound medium (commonly used in clinical settings as degassed water) between the three, namely: endoscopic ultrasound images show the entire wall of the digestive tract only when the site of the lesion is filled with water (degassed water in clinical practice). However, in clinical practice, a complete section of the wall of the digestive tract is difficult to show, especially in specific areas such as the esophagus, antrum, and turns of the intestine. The main reasons are that the water is difficult to inject or the water is difficult to retain after the water injection, so that the gas still occupies the tube cavity, the strong reflection of the ultrasonic wave is caused, and the ultrasonic image of the tube wall is difficult to completely display.
There have been reports on independent gastrointestinal endoscopic ultrasound examination assist balloons (patent nos. ZL2015 2 0307965.5. The balloon can successfully block water in a digestive tract cavity (mostly the part above physiological stenosis) in the Endoscopic Ultrasound (EUS) examination process to form the effect similar to a dam, thereby successfully finishing the EUS examination; moreover, due to the 'dam' function of the balloon, the water injection amount required by the EUS examination is greatly reduced, the examination time can be greatly shortened, and the pain of patients is reduced. However, one disadvantage of the above-mentioned auxiliary balloon is that the hardness of the catheter attached thereto is not sufficient, which makes the insertion of the balloon difficult in clinical application, and sometimes a snare or biopsy forceps is required to fix the front end thereof to an endoscope, which is passed through the endoscope and into the cardia or pylorus, thereby playing a role of a "dam".

Detailed Description
For better illustrating the objects, technical solutions and advantages of the present invention, the present invention will be further described with reference to the following embodiments.
As shown in fig. 1, an auxiliary balloon with a guide wire for ultrasonic examination of an endoscope in alimentary canal comprises: an adapter 1; the inflatable balloon 2 is inflated after water is injected; the catheter 3 is connected with the adapter 1 at one end and penetrates through the balloon 2 at the other end, wherein a water injection hole is formed in the part of the catheter 3 penetrating through the balloon 2; the guide wire 4 is arranged in the catheter 3, and the guide wire 4 can be pulled out after the balloon 2 is placed at the far end of a target position (such as cardia or pylorus) for digestive tract examination; and the switch joint 5 is used for connecting the adapter 1 after the guide wire 4 is pulled out of the catheter 3.
And (3) a balloon 2: the balloon 2 can be expanded and placed at the narrow part of the alimentary canal (such as cardia, pylorus, descending part of duodenum and the like) after water is injected, and can play a role of a dam after the endoscopic pore canal is injected with degassed water, so that an ultrasonic medium (degassed water) injected from the lumen is retained. The balloon 2 should have a suitable tension in its inflated state to resist the pressure of the degassed water retained in the upper alimentary tract without damaging the walls of the alimentary tract. In order to adapt to the anatomy of the human digestive tract and successfully complete the function of a dam for blocking water, the method comprises the following steps: after the saccule 2 is inflated by water injection, the diameter phi B of the saccule in the direction vertical to the catheter is 30-50mm, and the diameter L2 of the saccule in the direction parallel to the catheter is 20-30mm.
A conduit 3: a push tube connecting the balloon 2 and placing the balloon 2 in the alimentary tract, wherein one end of the push tube penetrating through the inside of the balloon 2 is closed. Because the saccule at the front end needs to be injected with water for expansion, the part of the pushing pipe penetrating through the inside of the saccule 2 is provided with water injection holes, the aperture phi A of the water injection holes is set to be 3.5-3.9 mm, and the number of the water injection holes is preferably less than or equal to 3; meanwhile, the push pipe is always positioned in the alimentary canal sound field in the process of checking the EUS, so that the push pipe is preferably made of sound-transmitting materials to ensure a good ultrasonic image, namely the guide pipe 3 is made of sound-transmitting materials, so that ultrasonic waves can be ensured to penetrate through the guide pipe during endoscopic ultrasonic checking, the reflection of the ultrasonic waves is reduced, and the whole alimentary canal wall and the lumen are completely displayed on the ultrasonic image; and the catheter should have certain hardness and softness so as to be smoothly inserted into the digestive tract. Based on the length of the digestive tract (particularly the upper digestive tract), we designed the length L1 of the catheter 3 to be 80-120cm and the outer diameter of the catheter 3 to be 3.5-4.0mm.
And (4) guide wire: the medical endoscope is inserted into the catheter 3 through the adapter 1 (without reaching the sacculus 2), the function of the medical endoscope is to keep certain hardness, the sacculus 2 is convenient to be inserted from the mouth or the nose in clinic, and the sacculus 2 is pushed to the stomach jet valve and other positions through the guide wire.
The switch joint 5: the switch joint 5 is opened, the physiological saline or the air is injected through the switch joint 5, the injected physiological saline or the air reaches the saccule 2 through the water injection hole of the catheter, so that the saccule 2 and the inner pore passage of the catheter are filled with the water or the air, then the switch joint 5 is closed, so that the water or the air in the catheter 3 and the saccule 2 cannot flow back out of the body, and the tension when the saccule 2 is in the water injection state and the water filling state in the water injection hole of the catheter 3 are ensured.
Adapter 1: connecting the switch fitting 5 and the conduit 3.
The utility model discloses take alimentary canal scope ultrasonic examination of seal wire assists the use of sacculus:
the adapter 1, the catheter 2, the balloon 2 and the guide wire 4 are assembled according to the drawing 1, when the digestive tract endoscope ultrasonic examination is needed, the balloon 2 in a retracted state can be firstly inserted into the digestive tract through a mouth or a nose, the balloon 2 is placed at the far end of a digestive tract examination target position (such as a stomach jet) through the guide wire 4, the guide wire 4 is taken out, the switch joint 5 is connected according to the drawing 2, the switch joint 5 is opened, the physiological saline or air is injected through the switch joint 5 to enable the balloon 2 to be in an expanded state (shown in the drawings 1 and 2), the switch joint 5 is closed, the balloon 2 is pulled back, so that the far end of the digestive tract examination target position is successfully plugged, the balloon 2 is clamped at the digestive tract examination target position (such as a cardiac gate part) to play a 'dam role', and then the degassed water is injected into the digestive tract lumen through an endoscope pore canal until the lumen is filled with the degassed water, and the ultrasonic endoscope examination can be carried out. After the detection is finished, the switch joint 5 is opened, and water or air in the ball bag can be sucked.
The animal experiment proves that: to last alimentary canal (including esophagus, stomach, duodenum ball descending part) and lower alimentary canal (rectum anal canal), use the utility model discloses, can be complete and clear show each layer structure of alimentary canal pipe wall, change and insert, image quality is good, receives the gas interference few, and the water injection volume is few moreover, and the check-up time is short.
