Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a nasobiliary duct oral-nose conversion finger ring device. Background Art

[0002] In digestive endoscopy ERCP, endoscopic nasobiliary drainage is a commonly used method. In nasobiliary drainage, the process of converting the nasobiliary duct from mouth to nose is difficult and an important step. In ENBD, after one end of the nasobiliary duct is placed in the bile duct, the other end of the nasobiliary duct is led out of the mouth along the duodenoscope. The next step is to convert the nasobiliary duct from the mouth to the nasal cavity. The commonly used method is to prepare a carrier tube (silicone gastric tube) and a guide wire. After the two ends of the guide wire are aligned, the other end forms a loop. The guide wire loop is inserted from the mouth to the posterior pharyngeal wall. At the same time, one end of the carrier tube is inserted from the nostril. After the guide wire loop on the posterior pharyngeal wall is wrapped around one end of the carrier tube, the carrier tube is pulled out of the mouth.

[0003] After the carrier tube is pulled out of the mouth, one end is outside the nasal cavity and the other end is outside the oral cavity. The end of the carrier tube outside the oral cavity is connected to the nasobiliary duct, and the end of the carrier tube outside the nasal cavity is pulled to complete the oral-nasal conversion of the nasobiliary duct. In actual operation, the crossed guide wires are easy to slip out of the hand and easy to coil in the oral cavity. These factors will hinder the smooth resetting of the nasobiliary duct. Therefore, this problem can be solved by combining the guide wire with the outer sleeve of the syringe, please refer to CN202022147820.7.

[0004] Nowadays, in the process of using the above method, it is found that the outer sleeve of the syringe is straight and hard, the direction change range in the oral cavity is small, the direction change is difficult to control, and there is a risk of oral damage. At the same time, it is impossible to judge whether the collection is successful in the mouth, and it is necessary to exit the mouth to determine. There is a possibility that repeated entry and exit may be required to successfully collect, and repeated entry and exit may damage the oral mucosa. Utility Model Content

[0005] The main purpose of the utility model is to provide a nasobiliary mouth-nose conversion ring device, aiming to solve the above technical problems.

[0023] The utility model provides a nasobiliary mouth-nose conversion finger ring device, which is used for the oral-nose conversion of the nasobiliary duct of a patient.

[0024] In this application, please refer to Figure 1-3The nasobiliary oral-nasal conversion finger ring device comprises a ring-shaped finger ring body 10 and a guide wire passing short tube 20 detachably mounted on the finger ring body 10. When in use, the operator wears the finger ring body 10 on the finger, then installs the guide wire passing short tube 20, fixes the guide wire passing catheter on the finger ring body 10, and the inner diameter of the short tube allows the double guide wires to pass freely, then inserts the disposable guide wire into the axial hollow hole 24 of the guide wire passing short tube 20, and the operator can insert the finger into the patient's oral cavity, and form a guide wire loop on the posterior pharyngeal wall by releasing the guide wire, and then sheath the silicone gastric tube inserted through the nostril, tighten the guide wire loop after sheathing, and confirm whether the silicone gastric tube is correctly sheathed by the fingertips, and the finger can pull the silicone gastric tube out of the oral cavity through the guide wire, and the end of the pulled-out silicone gastric tube is connected to the nasobiliary duct to complete the oral-nasal conversion of the nasobiliary duct.

[0025] In the present application, the guide wire is used to pull the gastric tube through the ring body 10 and the operator's fingers, making the nasobiliary duct to oral and nasal conversion more efficient and flexible. The silicone gastric tube can be pulled out efficiently and accurately judged to be pulled out only after the pull-out is successful, avoiding the possible oral damage caused by the guide wire and the corresponding outer tube entering the inlet and outlet pharynx multiple times.

[0026] Specifically, the ring body 10 has a through hole 11 at the axis center that matches the shape of the finger. Generally, the diameter of the through hole 11 is equal to the diameter of the operator's middle finger pulp, so that the ring body 10 can be clamped on the operator's middle finger pulp, so that the ring body 10 is located in the middle part of the finger, which can not only better clamp the ring body 10 through the finger, but also make the ring body 10 closer to the silicone catheter to improve convenience and stability. It is understandable that when operating the nasobiliary oronasal conversion, it will also be used with a gastroscopy mouth pad.

[0027] In the above embodiment, the finger ring body 10 is provided with a plurality of mounting holes 12, and the guide wire passing short tube 20 passes through the mounting holes 12. In this embodiment, by providing the mounting holes 12 to fix the guide wire passing short tube 20, the stability of the operator during operation can be improved.

[0028] Specifically, the guide wire passing short tube 20 includes a first blocking portion 21, a clamping portion 22 and a second blocking portion 23 connected to each other, the diameters of the first blocking portion 21 and the second blocking portion 23 are larger than the outer diameter of the clamping portion 22, and the outer wall surface of the clamping portion 22 contacts the inner wall surface of the mounting hole 12. Please refer to Figure 1-3In the present application, the guide wire passing short tube 20 is a hose, such as a rubber tube, a silicone tube, etc. Therefore, when installing the guide wire passing short tube 20, first squeeze the first blocking portion 21 along the height direction with your fingers so that it can be squeezed into the installation hole 12, and then continue to push the guide wire passing short tube 20 in the direction of inserting into the installation hole 12 until the first blocking portion 21 is separated from the installation hole 12. At this time, the first blocking portion 21 returns to its original state when the squeezing force of the inner wall of the installation hole 12 is removed, and the clamping portion 22 is just clamped in the installation hole 12, thereby completing the installation of the guide wire passing short tube 20.

[0029] After the guide wire passing short tube 20 is installed, the end surfaces of the first blocking portion 21 and the second blocking portion 23 facing each other will contact the two end surfaces of the finger ring body 10 respectively, thereby achieving the purpose of axial limitation, preventing the guide wire passing short tube 20 from falling off when the operator wears the finger ring body 10 and operates, thereby improving stability.

[0030] It is understandable that the number of the mounting holes 12 may be one or more. When there are multiple mounting holes 12 , the multiple mounting holes 12 may be evenly spaced along the circumferential direction on the finger ring body 10 .

[0031] In the above embodiment, the guidewire is a medical zebra guidewire, and the length of the guidewire can be 40-80 cm.

[0032] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the concept of the utility model, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
