Abstract
Description
Technical Field
[0001] This utility model relates to the field of surgical instruments, and in particular to an anesthetic cannula for surgical procedures. Background Technology
[0002] When a patient undergoes surgery, general anesthesia is usually required. Because the patient's nervous system is suppressed during general anesthesia, an anesthetic tube needs to be inserted into the lungs through the patient's throat, and then a ventilator is connected to provide passive breathing for the patient.
[0003] In existing technology, the end of the anesthetic tube closest to the lung is equipped with an air bag. After the anesthetic tube is inserted into the throat, the air bag is inflated and contacts the inner wall of the throat to prevent the anesthetic tube from shifting. Then, a breathing mask is inserted into the outer end of the anesthetic tube. Since the breathing mask is connected to the ventilator and has weight, and the anesthetic tube is vertical, when the breathing mask acts on the anesthetic tube, it will cause the anesthetic tube to shift slightly. Since part of the anesthetic tube will be pressed against the throat, it will put unnecessary pressure on the throat, making the patient's throat more uncomfortable after the operation. Utility Model Content
[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an anesthetic cannula for surgical procedures, which addresses the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0006] An anesthetic cannula for surgical procedures includes a ventilation tube and an abutment mechanism disposed on the outer cylindrical surface of the ventilation tube. The abutment mechanism is located at the end of the ventilation tube closest to the outside. The abutment mechanism includes an inflation assembly and a tightening assembly fixedly connected to the inflation assembly. The inflation assembly includes an inflation part and a first inflation line for supplying air to the inflation part. The inflation part has an upper dental sleeve and a lower dental sleeve disposed opposite to each other. The upper dental sleeve has an upper abutment surface that abuts against the surface of the upper teeth and an upper occlusal surface that contacts the tip of the upper teeth. The lower dental sleeve has a lower abutment surface that abuts against the surface of the lower teeth and a lower occlusal surface that contacts the tip of the lower teeth.
[0007] According to one aspect of the above technical solution, the inflation part is made of silicone material, and a one-way valve is provided at the position where the inflation part is connected to the first inflation line.
[0008] According to one aspect of the above technical solution, the tensioning component includes a sliding ring and a tensioning ring disposed at both ends of the inflation part, the sliding ring and the tensioning ring being used to slide close to the ventilation hose.
[0009] According to one aspect of the above technical solution, the end of the tension ring away from the inflation part is provided with a stress relief groove at an annular interval, and a nut is threaded onto the tension ring.
[0010] According to one aspect of the above technical solution, the outer cylindrical surface of the tightening ring is provided with external threads, and the inner wall of the nut is provided with internal threads.
[0011] According to one aspect of the above technical solution, the ventilation hose is provided with an airbag mechanism at the end closest to the patient's lung cavity.
[0012] According to one aspect of the above technical solution, the airbag mechanism includes an airbag body located on the outer cylindrical surface of the ventilation hose, and fixing rings disposed at both ends of the airbag body, wherein the fixing rings are fixedly connected to the outer cylindrical surface of the ventilation hose.
[0013] According to one aspect of the above technical solution, the airbag mechanism further includes a second inflation line, which enters the air hose from the end of the air hose closest to the outside and connects to the airbag body from the inside of the air hose. A one-way valve is provided at the connection position between the airbag body and the second inflation line.
[0014] According to one aspect of the above technical solution, the end of the ventilation hose closest to the outside is provided with a connecting tube for connection to a ventilator.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] By setting an abutment mechanism on the outer cylindrical surface of the ventilation tubing, after the anesthesia cannula is inserted into the patient's throat, the inflation component is moved to the patient's teeth and then fixed by the tightening component. In the initial state, the inflation part is empty of air but has a basic shape. The upper and lower dental braces in the initial state are placed on the patient's upper and lower teeth respectively, and then air is pumped into the inflation part from the first inflation line, so that the upper abutment surface and upper occlusal surface of the upper dental brace cover the patient's upper teeth, and the lower abutment surface and lower occlusal surface of the lower dental brace cover the patient's lower teeth. Firstly, by fixing the inflation part to the patient's teeth, the ventilation tubing will not put excessive pressure on the patient's throat after the ventilator is turned on. Secondly, if the patient unexpectedly wakes up on their own, it will prevent the patient from subconsciously clenching their upper and lower jaws, which could lead to adverse consequences.
[0017] This invention can reduce the pressure of the ventilation tube on the patient's throat and prevent the patient from unconsciously clenching their jaw when they wake up unexpectedly, which could lead to adverse consequences. Attached Figure Description

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0028] Please see Figures 1 to 4The image shows a surgical anesthesia cannula according to the first embodiment of this utility model, including a ventilation hose 10 and an abutment mechanism 20 disposed on the outer cylindrical surface of the ventilation hose 10. The abutment mechanism 20 is located at the end of the ventilation hose 10 closer to the outside. The abutment mechanism 20 includes an inflation component and a tightening component fixedly connected to the inflation component. The inflation component includes an inflation part 21 and a first inflation line 24 for supplying air to the inflation part 21. The inflation part 21 has an upper dental sleeve 25 and a lower dental sleeve 26 disposed opposite to each other. The upper dental sleeve 25 has an upper abutment surface 252 that abuts against the upper tooth surface and an upper occlusal surface 251 that contacts the tip of the upper tooth. The lower dental sleeve 26 has a lower abutment surface 262 that abuts against the lower tooth surface and a lower occlusal surface 264 that contacts the tip of the lower tooth.
[0029] Understandably, this utility model provides an abutment mechanism 20 on the outer cylindrical surface of the ventilation hose 10. After the anesthesia cannula is inserted into the patient's throat, the inflation component is moved to the patient's teeth and fixed by the tightening component. In the initial state, the inflation part 21 is empty but has a basic shape. The upper dental sleeve 25 and lower dental sleeve 26 in the initial state are respectively placed on the patient's upper and lower teeth. Then, air is pumped into the inflation part 21 from the first inflation line 24, so that the upper abutment surface 252 and upper occlusal surface 251 of the upper dental sleeve 25 cover the patient's upper teeth, and the lower abutment surface 262 and lower occlusal surface 264 of the lower dental sleeve 26 cover the patient's lower teeth. Firstly, by fixing the inflation part 21 to the patient's teeth, the ventilation hose 10 will not exert excessive pressure on the patient's throat after the ventilator is turned on. Secondly, when the patient unexpectedly wakes up, it prevents the patient from subconsciously clenching their upper and lower jaws, which could lead to adverse consequences.
[0030] This invention can reduce the pressure of the ventilation hose 10 on the patient's throat, and at the same time prevent the patient from unconsciously clenching their upper and lower jaws when they wake up unexpectedly, which could lead to adverse consequences.
[0031] Specifically, in this embodiment, the inflation part 21 is made of silicone material, and a one-way valve is provided at the position where the inflation part 21 is connected to the first inflation line 24.
[0032] Understandably, silicone material is inflatable and non-toxic and odorless, making it very suitable for wrapping patients' teeth. The purpose of setting a one-way valve on the first inflation line 24 is to allow gas to enter but not exit, requiring manual extraction to prevent gas leakage.
[0033] Furthermore, the ventilation hose 10 is provided with an airbag mechanism 30 at one end near the patient's lung cavity; the airbag mechanism 30 includes an airbag body 31 located on the outer cylindrical surface of the ventilation hose 10, and fixing rings 32 respectively disposed at both ends of the airbag body 31, the fixing rings 32 being fixedly connected to the outer cylindrical surface of the ventilation hose 10; the airbag mechanism 30 also includes a second inflation line 33, the second inflation line 33 entering the ventilation hose 10 from the end of the ventilation hose 10 near the outside and connecting to the airbag body 31 from the inside of the ventilation hose 10, and a one-way valve is provided at the connection position between the airbag body 31 and the second inflation line 33.
[0034] Understandably, once the patient's glottis is opened using a laryngoscope, the ventilation tube 10 can be inserted into the lung cavity through the glottis. Then, by inflating the second inflation line 33, air enters the cuff body 31, causing the cuff body 31 to expand and become lodged in the patient's throat, stabilizing the position of the ventilation tube 10 and preventing it from shifting during surgery, which could lead to the patient being unable to receive oxygen and thus causing danger. The one-way valve on the second inflation line 33 is designed to allow air to enter but not exit, requiring manual extraction to prevent air leakage.
[0035] Furthermore, the tensioning assembly includes a sliding ring 22 and a tensioning ring 23 respectively disposed at both ends of the inflation part 21. The sliding ring 22 and the tensioning ring 23 are used to slide close to the ventilation hose 10. The tensioning ring 23 is provided with a stress relief groove 233 at an annular interval at one end away from the inflation part 21. A nut 234 is threadedly connected to the tensioning ring 23. An external thread 231 is provided on the outer cylindrical surface of the tensioning ring 23, and an internal thread 232 is provided in the inner wall of the nut 234.
[0036] Understandably, in the initial state, the sliding ring 22 and the tension ring 23 simply slide against the ventilation hose 10. After the airbag body 31 is opened, the sliding ring 22 and the tension ring 23 are slid according to the position of the patient's teeth until the inflation part 21 is aligned with the patient's teeth. Then, by rotating the nut 234 from the tension ring 23 toward the part with the stress relief groove 233, the part of the tension ring 23 with the stress relief groove 233 is tightened, thereby ensuring the stability of the position of the tension part and the inflation part 21, and preventing the inflation part 21 and the tension part from sliding into the patient's mouth together when the ventilation hose 10 is removed after the operation.
[0037] It should be noted that the tension ring 23 should be made of an elastic material, and should not be made of a material that is too rigid, so as to prevent the tension ring 23 from failing to tighten at the location where the stress relief groove 233 is provided.
[0038] Furthermore, the ventilation hose 10 has a connecting tube 11 for connection to the ventilator at the end closest to the outside.
[0039] In summary, the surgical anesthesia cannula in the above embodiments of this utility model can reduce the pressure of the ventilation tube on the patient's throat, and at the same time prevent the patient from unconsciously clenching their upper and lower jaws when they wake up unexpectedly, which could lead to adverse consequences.
