Description

Technical Field

[0001] This utility model relates to the field of esophageal stent technology, and in particular to an esophageal stent fixation device. Background Technology

[0002] Esophageal stent fixation devices can accurately measure various angles of the nose, including nasal goniometers and nasal angle rulers, to meet different surgical needs. Through precise measurement and positioning, they help doctors better plan surgical procedures, thereby achieving more ideal surgical results.

[0003] An existing esophageal stent fixation device (publication number: CN215273607U) has at least the following drawbacks: several tubes are wrapped around the patient's ear, and the tubes are positioned by a contraction ring, so that the nasal plug is positioned on the patient's face, thereby fixing the esophageal stent in place. However, when the contraction ring contracts, the tubes are squeezed on the patient's chin, and the contraction ring can easily affect the patient's swallowing when swallowing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an esophageal stent fixation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An esophageal stent fixation device includes a nasal clip, an elastic tubing, and an elastic cord. The elastic tubing and the elastic cord are fixedly connected to both ends of the nasal clip. A rigid sleeve is fixedly connected to one end of the elastic tubing. A double-hole spring buckle is provided on one side of the rigid sleeve. The elastic tubing is externally and fixedly connected to the positioning hole of the double-hole spring buckle. An ear loop is fixedly connected to the end of the elastic cord away from the nasal clip.

[0007] As a further embodiment of this utility model, the ear loop and the outer side of the elastic tube are both fixedly adhered with adhesive tape, and a soft tube is fixedly connected to the outer side of the end of the elastic tube near the nose clip.

[0008] As a further embodiment of this utility model, the elastic tube is hollow inside, and the soft tube, the rigid sleeve and the elastic tube are all interconnected inside, with a positioning block threaded to one end of the rigid sleeve.

[0009] As a further embodiment of this utility model, a positioning rope is fixedly connected inside the end of the positioning block near the rigid sleeve, and one end of the positioning rope passes through the rigid sleeve and the elastic tube and is slidably connected inside the soft tube.

[0010] As a further embodiment of this utility model, a wire tube is fixedly connected to the side of the nose clip near the soft rubber tube, and the soft rubber tube is fixedly connected inside the wire tube.

[0011] As a further embodiment of this utility model, an elastic frame is fixedly connected inside the nose clip, and the elastic tube, elastic rope and soft tube are all located in the middle of the nose clip.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The elastic cord and ear loop at one end of the nasal clip are elastic. The patient can stretch the elastic cord to put the ear loop on the ear. The patient then bends the elastic tube and wraps it around the other ear, pressing the double-hole spring to align the positioning holes on the double-hole spring. One end of the elastic tube connected to the positioning block passes through the positioning hole of the double-hole spring buckle. Depending on the patient's comfort, the double-hole spring buckle is pushed to slide on the elastic tube, adjusting the bending length of the elastic tube. When the patient releases their grip, the spring inside the double-hole spring buckle returns to its original position, causing the positioning holes to misalign and clamp the elastic tube in place. This facilitates the positioning of the esophageal stent and prevents the wearing of the fixation device from affecting the patient's swallowing movements.

[0014] 2. An elastic frame is fixed inside the nasal clip, giving it a certain degree of elasticity. This allows the nasal clip to be held between the patient's nasal columella, preventing it from shifting due to the patient's clothing rubbing against it and affecting the fixation of the esophageal stent. A positioning rope is installed between the esophagus and the esophagus, with its end fixedly connected to a positioning block. The positioning block is threadedly connected to a rigid tube. Medical staff can rotate the positioning block to release it from the elastic tube, and then stretch the positioning rope to move the esophageal stent upwards and remove it through the nasal cavity. The positioning rope inside the nasal cavity is covered with a soft tube to prevent friction from stretching the positioning rope and causing discomfort to the patient's nasal cavity.

[0023] In use, the elastic cord 5 at one end of the nasal clip 1 and the ear loop 501 are elastic. The patient can stretch the elastic cord 5 to put the ear loop 501 on the ear. The patient then bends the elastic tube 2 and wraps it around the other ear, presses the double-hole spring buckle 3 to align the positioning holes on the double-hole spring buckle 3, and passes one end of the elastic tube 2 connected to the positioning block 4 through the positioning hole of the double-hole spring buckle 3. According to the patient's own wearing comfort, the double-hole spring buckle 3 is pushed to slide on the elastic tube 2 to adjust the bending length of the elastic tube 2. When the patient releases his hand, the spring inside the double-hole spring buckle 3 returns to its original position, so that the positioning holes are misaligned to clamp and fix the elastic tube 2, which is conducive to the positioning of the esophageal stent and avoids the wearing of the fixation device from affecting the patient's swallowing action.

[0024] In this embodiment, the ear loop 501 and the outer side of the elastic tube 2 are both fixedly attached with tape 6, and the outer side of the end of the elastic tube 2 near the nose clip 1 is fixedly connected with a soft tube 202.

[0025] When using it, the patient uses tape 6 to attach the ear loop 501 and the elastic tube 2 to the back of the left and right ears to prevent the ear loop 501 and the elastic tube 2 from sliding on the ears and causing friction, which could abrasion the patient's skin and affect the wearing of the fixation device.

[0026] In this embodiment, the elastic tube 2 is hollow inside, and the soft tube 202, the rigid tube sleeve 201 and the elastic tube 2 are all interconnected. One end of the rigid tube sleeve is threaded with a positioning block 4.

[0027] When in use, the elastic tubing 2 and the soft tubing 202 are sleeved on the outside of the positioning rope 401 to protect the positioning rope 401 from oxidation caused by exposure to air, and also to prevent the positioning rope 401 from directly adhering to the patient's facial skin and causing abrasions.

[0028] In this embodiment, a positioning rope 401 is fixedly connected to the end of the positioning block 4 near the rigid sleeve. One end of the positioning rope 401 passes through the rigid sleeve 201 and the elastic tube 2 and is slidably connected inside the soft tube 202.

[0029] When in use, medical staff rotate the positioning block 4 to release the fixed connection between the positioning block 4 and the elastic tube 2, and stretch the positioning rope 401 to move the esophageal stent upward and remove it through the nasal cavity.

[0030] In this embodiment, a wire tube 102 is fixedly connected to the side of the nose clip 1 near the soft rubber tube 202, and the soft rubber tube 202 is fixedly connected inside the wire tube 102.

[0031] When in use, the positioning rope 401 located inside the nasal cavity is covered with a soft rubber tube 202 to prevent the stretching of the positioning rope 401 from causing friction to the patient's nasal cavity and causing discomfort.

[0032] In this embodiment, an elastic frame 101 is fixedly connected inside the nose clip 1, and the elastic tube 2, elastic rope 5 and soft tube 202 are all located in the middle of the nose clip 1.

[0033] When in use, the nasal clip 1 has an elastic frame 101 fixedly installed inside, which makes the nasal clip 1 have a certain elasticity, so that the nasal clip 1 can be clamped between the patient's nasal columella, and prevent the patient's clothing from scratching the nasal clip 1, causing it to shift and affect the fixation of the esophageal stent, thus having a fixation effect on the nasal clip 1.

[0034] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The elastic cord 5 and ear loop 501 at one end of the nasal clip 1 are elastic, and the patient can stretch the elastic cord 5 to put the ear loop 501 on the ear. The patient then bends the elastic tube 2 and wraps it around the other ear, presses the double-hole spring buckle 3 to unify the positioning holes on the double-hole spring buckle 3, and one end of the elastic tube 2 connected to the positioning block 4 passes through the positioning hole of the double-hole spring buckle 3. According to the patient's own wearing comfort, the double-hole spring buckle 3 is pushed to slide on the elastic tube 2 to adjust the bending length of the elastic tube 2. When the patient releases his hand, the spring inside the double-hole spring buckle 3 returns to its original position, so that the positioning holes are misaligned to clamp and fix the elastic tube 2, which is beneficial to the positioning of the esophageal stent and avoids Wearing a non-fixation device does not affect the patient's swallowing movements. An elastic frame 101 is fixedly installed inside the nasal clip 1, giving the nasal clip 1 a certain degree of elasticity, making it easy for the nasal clip 1 to be clamped between the patient's nasal columella. This prevents the nasal clip 1 from being displaced by the patient's clothing and affecting the fixation of the esophageal stent. A positioning rope 401 is installed between the esophagus and the esophagus. The end of the positioning rope 401 is fixedly connected to the positioning block 4. The positioning block 4 is threadedly connected to the rigid tube sleeve 201. Medical staff can rotate the positioning block 4 to release the fixed connection between the positioning block 4 and the elastic tube 2, and stretch the positioning rope 401 to move the esophageal stent upward and remove it through the nasal cavity. The positioning rope 401 located inside the nasal cavity is covered with a soft tube 202 to prevent the stretching of the positioning rope 401 from causing friction to the patient's nasal cavity and causing discomfort.
