Description

Technical Field

[0001] The utility model belongs to the technical field of nasal dilator devices, and in particular relates to a nasal dilator with a light. Background Art

[0002] A nasal dilator is a medical device used to dilate the nostrils, making it easier to observe or operate the internal structures and lesions of the nasal cavity. A nasal dilator is usually composed of two or more dilating pieces, one end of which is fixed together, and the other end is provided with a relatively convex arc piece, the shape of which is adapted to the internal shape of the nasal vestibule. The middle part of the nasal dilator is usually provided with an expansion device to open the dilating pieces, such as a spring, spiral, lever, etc.

[0003] The method of using a nasal dilator is to insert the dilator into the nostril, and then push the dilator outward through the dilator to expand the hole, thereby providing space for cavity inspection or treatment. The advantage of a nasal dilator is that it can effectively expand the nostril, reduce irritation and damage to the inside of the nasal cavity, and improve the effectiveness and safety of nasal inspection or treatment.

[0004] However, the disadvantage of the nasal dilator is that during use, since there is no lighting equipment at the front end insertion part of the nasal dilator, the view inside the cavity is unclear, making it difficult to observe the structure and lesions inside the nasal cavity and not conducive to precise operation.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted here that the "distal end" mentioned in the present invention is the end close to the operator, and the "proximal end" is the end close to the operator. The specific details can be determined by referring to the accompanying drawings.

[0027] like Figure 1-3 As shown, a nose dilator with light comprises a nose dilating forceps body 1, wherein the nose dilating forceps body 1 comprises a first forceps body 11 and a second forceps body 12, wherein the first forceps body 11 and the second forceps body 12 are movably connected via a forceps body mounting shaft 101, wherein the distal ends of the first forceps body 11 and the second forceps body 12 are respectively provided with a first distal end 111 and a second distal end 121, and the distal end surfaces of the first distal end 111 and the second distal end 121 are provided with a detachable insertion expansion portion 3;

[0028] The insertion and expansion part 3 includes a connecting part 31 connected to the nose expansion forceps body 1 and an insertion part 32 for extending into the nasal cavity. The angle between the axis of the insertion part 32 and the connecting part 31 is 90°-135°, which is convenient for medical staff to operate and does not block the line of sight; the outer side of the insertion part 32 is a circular arc surface, which can avoid contact with the patient's nasal skin and cause discomfort.

[0029] The side where the two inserted opening parts 3 are close to each other is an inner plane 33, and a light point 34 for lighting is installed on the inner plane 33. The light point 34 can be one of LED, OLED, and miniLED. The light point 34 is powered by a lithium battery, and the lithium battery is installed in the installation cavity in the inserted opening part 3;

[0030] In some disclosures, the light-emitting point is one of LED, OLED or miniLED, and the light-emitting point is powered by a lithium battery. The lithium battery is installed in an installation cavity inserted into the expansion part, and the battery can be charged by wireless charging.

[0031] The outer shell of the insert support part 3 is produced by plastic injection molding and adopts a split design, which can facilitate the installation of internal batteries and circuits. Furthermore, the inner plane 33 is made of transparent plastic so that the light-emitting point 34 can be set inside the insert support part 3 to avoid damage to the light-emitting point 34 caused by external force.

[0032] The hand-held parts of the first pliers body 11 and the second pliers body 12 are respectively provided with a first mounting block 21 and a second mounting block 22, and the first mounting block 21 and the second mounting block 22 are provided with a first spring piece 211 and a second spring piece 221 that conflict with each other. The mutual conflict between the first spring piece 211 and the second spring piece 221 causes the first pliers body 11 and the second pliers body 12 to open outward, thereby driving them to rotate around the pliers body mounting axis 101 to drive the insertion expansion part 3 to open. When in use, it is only necessary to forcefully close the first pliers body 11 and the second pliers body 12 and then place them into the nasal cavity to reduce the pressure on the first pliers body 11 and the second pliers body 12 to achieve automatic expansion of the insertion expansion part 3. Furthermore, the first pliers body 11 and the second pliers body 12 can also be expanded by a spring.

[0033] In some embodiments, the insert expansion part 3 can be installed by means of threads, magnetic interference fit, etc. In the utility model, the magnetic method is adopted, and the distal end faces of the first clamp body 11 and the second distal end 121 are both provided with a first mounting groove 13, and the proximal end of the insert expansion part 3 is provided with a positioning mounting boss 311 movably mounted in the first mounting groove 13, and the bottom surface of the first mounting groove 13 and the end surface of the positioning mounting boss 311 are both provided with magnets that are magnetically fixed to each other, so that the insert expansion part 3 can be easily disassembled and installed.

[0034] In some embodiments, the light emitting point 34 is controlled by a switch. The switch can be set on the light emitting point 34 or at the distal end of the insertion expansion portion 3. The switch can be a key switch.

[0035] In some embodiments, the driving circuit of the light-emitting point 34 is provided with two safety contacts 312 on the end face of the positioning mounting boss 311. Only when the positioning mounting boss 311 is installed in the first mounting groove 13 and the contact point in the first mounting groove 13 that cooperates with the safety contact 312 collides with the two safety contacts 312, the circuit of the light-emitting point 34 is open, and the contact point can be two interconnected pins.

[0036] Furthermore, a capacitive contact switch 321 is provided on the outer side of the insertion portion 32. The capacitive contact switch 321 is an electric capacitance contact switch. The capacitive contact switch 321 is used to control the switch of the light-emitting point 34. When the capacitive contact switch 321 contacts the patient's tissue, it is in a connection state, thereby turning on the switch of the light-emitting point 34.
