Description

SUPPORT FOR NOSE SURGERY

The present invention relates to a support for nose surgery. More specifically, it relates to a support for nose surgery which facilitates respiration of a patient after surgery, by forming a respiration flow passage for respiration inside a support section of the support for nose surgery.

A nose is anatomically constituted of an external nose protruding from a face and a nasal cavity that forms an inside thereof.

Referring to Fig. 1, a nasal cavity 30 is located inside a nostril of a nose 10, and three pleats covered with mucous membranes called a superior nasal concha 31, a middle nasal concha 33, and an inferior nasal concha 35 are formed in the nasal cavity 30 so as to be divided into two sides. An air passage located between the superior nasal concha 31 and the middle nasal concha 33 is called a superior nasal meatus 32, an air passage located between the middle nasal concha 33 and the inferior nasal concha 35 is called a middle nasal meatus 34, and a space located between the inferior nasal concha 35 and a hard palate is called an inferior nasal meatus 36. The flow of air during respiration is performed via the nasal meatus, and most respiration is done through the middle nasal meatus 34.

In general, a support for maintaining the shape of the nose 10 during surgery of the nose is inserted in a direction from the inferior nasal concha 35 to the superior nasal concha 31 within the nasal cavity 30 so as to support the external nose 20. However, in such a case, there has been a problem in which the air passage is blocked to make the patient’s respiration difficult.

The present invention provides a support for nose surgery which facilitates respiration of a patient during surgery, by forming a respiration flow passage for respiration inside a support section of the support for nose surgery.

According to an aspect of the present invention, there is provided a support that maintains the shape of the nose during the nose surgery, the support including a support section that is inserted into a nasal cavity, and supports an external nose by expansion of volume depending on the supply of the liquid; and a respiration flow passage that penetrates through the support section, and has one end formed to face a nasal meatus within the nasal cavity.

At this time, the nasal meatus may be a middle nasal meatus between a middle nasal concha and an inferior nasal concha.

In addition, the nasal meatus may be an inferior nasal meatus between the inferior nasal concha and the hard palate.

At this time, the support section may be formed of a material containing Polyvinyl Alcohol (PVA) or Polyvinyl Acetate (PVAc).

Also, the respiration flow passage may be formed in the support section to be inclined so that the other end faces a nostril.

Also, the respiration flow passage may be formed by being bent in the interior of the support section so that the other end faces the nostril.

At this time, the support may further include a support ring that is located in the respiration flow passage to support an inner wall of the support section.

Also, the respiration flow passage may include a tube which is inserted into the support section, and one end of which protrudes so as to face the middle nasal meatus.

Also, a plurality of respiration holes may be formed at an end portion of the tube.

The other end portion of the tube may be formed such that the cross-sectional area increases toward the other end.

Also, a plurality of protrusions may be formed on an outer circumference of the tube.

Furthermore, the tube may consist of a biocompatible compound selected from a group that includes silicon, polyurethane, polyethylene, polypropylene, polypropylethylene, Teflon, prolene, nylon, polydioxanone, polyglycolic acid, polylactic acid, and polyglycol-lactic acid.

In addition, the tube may have a form of a pleated tube.

In addition, an inner diameter of the tube may be 3 mm to 8 mm.

Further, the support section may be a first main body that is inserted into the nasal cavity to support the external nose, and a second main body that is hinged to the first main body so as to rotate and is formed with a respiration flow passage.

At this time, one end portion of the second main body is inserted into the first main body, and a hinge pin is coupled to the one end portion, whereby the second main body can rotate.

Further, stepped portions are formed on each one surface of the first main body and the second main body, and the second main body can be hinged to the first main body so as to rotate by a hinge pin so that the stepped portions face each other.

According to an embodiment of the present invention, respiration of the patient during surgery can be facilitated, by forming a respiration flow passage for respiration inside the support section of the support for nose surgery.

Hereinafter, an embodiment of a support for nose surgery according to the present invention will be described in detail with reference to the accompanying drawings, and in the description with reference to the accompanying drawings, the identical or corresponding components will be denoted by the same reference numerals.

Fig. 2 is a cross-sectional view schematically showing a support for nose surgery according to one embodiment of the present invention, Fig. 3 is a cross-sectional view schematically showing a modified example of the support for nose surgery according to one embodiment of the present invention.

Figs. 2 and 3 show a support for nose surgery 100, a support section 110, and a respiration flow passage 130.

The support of nose surgery 100 according to the present embodiment includes a support section 110 and a respiration flow passage 130.

The support section 110 is inserted into a nasal cavity 30, and its volume expands according to the supply of the liquid to support the external nose 20. Specifically, the support section 110 is inserted into the nasal cavity 30 so as to be inclined upward in the direction from an inferior nasal concha 35 to a superior nasal concha 31, and its volume expands according to the supply of the liquid to support the external nose 20. At this time, the liquid can be blood, saline water, water and the like.

The supply of liquid of the support section 110 in the treatment process can be carried out by saline water injected via a syringe or the like, or absorption of blood occurring in the treatment process through the surface of the support section 110.

Further, the support section 110 can act as a hemostatic body by compressing a bleeding site of Kisselbach (a part in which capillaries are concentrated in front of a nasal septum) according to the volume expansion.

That is, the support section 110 performs the function as a support for maintaining the shape of the nose during the nose surgery, but it can also perform a function as a hemostatic body that compresses the bleeding site and stops the bleeding when the bleeding from the surgical process occurs.

The respiration flow passage 130 penetrates through the support section 110, and one end 131 faces the middle nasal meatus 34 in the nasal cavity 30.

The respiration flow passage 130 is a passage through which air flows, and facilitates the respiration of patient during surgery.

The one end 131 of the respiration flow passage 130 faces the middle nasal meatus 34, and communicates with the middle nasal meatus 34 by being located between the middle nasal concha 33 and the inferior nasal concha 35 when the support section 110 expands. Since most air flows through the middle nasal meatus 34 during practical respiration, when the respiration flow passage 130 communicates with the middle nasal meatus 34, the patient's respiration is most easy (see Fig. 1).

Therefore, when one end 131 of the respiration flow passage 130 faces the middle nasal meatus 34, there is an effect in which respiration of the patient is further facilitated during surgery.

However, one end of the respiration flow passages 130 preferably faces the middle nasal meatus 34. However, since some respiration is performed through the inferior nasal meatus 36 of nasal meatuses (see Fig. 1), the respiration flow passage 130 may also be formed to face the inferior nasal meatus 36 so as to communicate with the inferior nasal meatus 36.

Hereinafter, the description will be mainly given for a case where the respiration flow passage 130 faces the middle nasal meatus 34.

Meanwhile, the support section 110 may be formed of a material containing Polyvinyl Alcohol (PVA) or Polyvinyl Acetate (PVAc) or polyurethane.

PVA or PVAc or polyurethane is a porous material that forms a continuous open-cell structure, and there are advantages of excellent absorption and durability and easy porosity and standards regulation.

Thus, when the support section 110 is formed of PVA or PVAc, the absorption of the blood is excellent during treatment due to high absorption, the volume expands when absorbing blood using a porous material, and there are excellent effects as a hemostatic body and external nose support.

Meanwhile, the respiration flow passages 130 may be formed to be inclined so that one end 131 faces the middle nasal meatus 34 and the other end 133 faces the nostrils.

Fig. 3 is a modified example of the support for nose surgery according to this embodiment, the respiration flow passage 130 is bent inside the support section 110, and are formed so that one end 131 of the respiration flow passage 130 faces the middle nasal meatus 34, and the other end 133 face the nostrils. At this time, since the other end 153 of the respiration flow passage 130 is close to the nostrils, it is advantageous for respiration during nasal surgery.

Meanwhile, a support ring 135 may be positioned in the respiration flow passage 130 of this embodiment.

The support ring 135 is installed on the respiration flow passage 130 in an approximately hollow cylindrical shape to support the inner wall of the support section 110.

At this time, a plurality of support rings 135 may be positioned on the respiration flow passage 130.

The support ring 135 is formed of a rigid material, and prevents the respiration flow passage 130 from being narrowed by the expansion of the support section 110 that has absorbed liquid during the nose surgery.

Fig. 4 is a cross-sectional view schematically showing a support for nose surgery according to another embodiment of the present invention, Fig. 5 is a cross-sectional view schematically showing a modified example of the support for nose surgery according to another embodiment of the present invention, Fig 6 is a cross-sectional view schematically showing another modified example of the support for nose surgery according to another embodiment of the present invention, and Fig. 7 is a cross-sectional view schematically showing another modified example of the support for nose surgery according to another embodiment of the present invention.

Fig. 4 illustrates the support for nose surgery 100, the support section 110, tube 150, and the respiration hole 155.

The support for nose surgery 100 according to this embodiment is the same as the above-mentioned embodiment, with the exception of the configuration of the tube 150, and the same configurations are replaced with the description of the above-mentioned embodiment.

The support for nose surgery 100 according to this embodiment includes the support section 110 and the tube 150.

The tube 150 is inserted into the support section 110 and one end 151 to protrude so as to face the middle nasal meatus 34. The protruding one end 151 is inserted into the middle nasal meatus 34 located between the middle nasal concha 33 and the inferior nasal concha 35, and communicates with the middle nasal meatus 34. When the respiration flow passage 150 includes the tube 150, since the protruding one end 151 of the tube 150 may be formed near the middle nasal meatus 34, there is an effect that is beneficial for the patient's respiration (see Figs. 18 to 21).

At this time, tube 150 may be formed to be inclined so that one end 151 faces the middle nasal meatus 34 and the other end 153 faces the nostrils. The cross-section of the tube 150 may include various shapes serving as a flow passage through which air flows, such as circular, oval, and rectangular forms.

Meanwhile, a plurality of respiration holes 155 may be formed at the end portion of the tube 150. At this time, the end portion may be one of the both end portions of the tube 150, and may include both end portions.

The respiration hole 155 increases the flow rate of air at the end portions to facilitate the patient's respiration.

The other end portion of the nostril side of the end portions of the tube 150 may be formed so that the cross-sectional area increases toward the other end 153. The reason is that the tube 150 serves as a locking jaw so as to prevent from being separated from the support section 110, thereby preventing the tube 150 from being detached from the support section 110 and entering the nasal cavity during the patient's inspiratory.

On the other hand, fine irregularities may be formed on the outer circumference of the tube 150 to roughly form the surface, which is to prevent the tube 150 from being detached from the support section 110, by increasing the roughness of the surface.

At this time, a plurality of protrusions 157 may be formed on the outer circumference of the tube 150. This is in order that the tube 150 serves as a locking protrusion that prevents the tube 150 from being separated from the support section 110, thereby preventing the tube 150 from being detached from the support section 110.

A reinforcing member for reinforcing the strength of the tube 150 may be provided on the outer circumference of the tube 150, and the reinforcing member reinforces the strength of the tube 150 so that the tube 150 can withstand the external pressure.

At this time, the reinforcing member may increase the strength of the tube 150 by being wound around the outer circumference in a spiral shape, or may increase the strength of the tube 150 by being attached to the outer circumference while being separated at a predetermined interval.

Meanwhile, the tube 150 may be constituted of a multiple walls having different strength, and the multiple walls enhance the strength of the tube 150.

On the other hand, the tube 150 may be formed of biocompatible compounds such as, silicon, polyurethane, polyethylene, polypropylene, polypropylethylene, Teflon, prolene, nylon, polydioxanone, polyglycolic acid, polylactic acid, and polyglyco-lactic acid.

This is to prevent side effects due to toxicity since the tube 150 is inserted into the body during treatment.

Fig. 5 is a modified example of the support for nose surgery according to this embodiment that is formed so that the tube 150 is bent inside the support section 110, one end 151 of the tube 150 faces the middle nasal meatus 34, and the other end 153 faces the nostrils. In this case, since the other end 153 of the tube 150 is close to the nostrils, it is advantageous for respiration during nose surgery.

Meanwhile, referring to Figs. 6 to 9, the tube 150 may be in the form of a pleated tube.

The pleated tube may be formed in the entire or a part of main body of the tube 150, and this will be described below.

Fig. 10 is a bottom view schematically showing the support for nose surgery according to another embodiment of the present invention, Fig. 11 is a front view schematically showing the support for nose surgery according to another embodiment, and Fig. 12 is an operational state diagram thereof. Also, Figs. 13 and 14 are diagrams of modified examples schematically showing the support for nose surgery according to another embodiment of the present invention. Also, Fig. 15 is a perspective view schematically showing another modified example of the support for nose surgery according to another embodiment of the present invention, Fig. 16 is a front view thereof, and Fig. 17 is an operational state diagram.

The tube 150 of Figs. 6 to 17 may be in the form of a pleated tube.

The pleated tube may be formed in all or a part of the main body of the tube 150, and the pleat form may be a common bellows or a spiral pleat.

In this embodiment, the description will be mainly given of a case where the pleated tube is in a bellows form.

When the pleat is formed in the main body of the tube 150 body, it is possible to withstand the pressure in the vertical direction (radial direction) to the tube 150.

Also, since the tube 150 may be bent to a desired angle by the pleat, one end of the tube 150 may be more easily located in the middle nasal meatus 34.

In addition, the tube 150 may be prevented from being disengaged from the support section 110 or a second main body 123 described later through the pleat of the tube 150.

Also, since the length of the 150 may be adjusted, one end of the tube 150 may be easily located in the middle nasal meatus 34, by appropriately adjusting the length of the tube 150 depending on the nasal structure of the patient.

Preferably, the inner diameter of the tube 150 may be 3 mm to 8 mm. When the tube 150 is a pleated tube, an inner diameter (D, see Figs. 7, 9, 11 and 16) is a distance between the top parts of the valleys (sites extending inward from the wall of the bellows tube) of the pleats that face each other. If the inner diameter is large, the respiration flow passage increases, and there is an advantage of respiration during surgery. However, since there is a problem in that the size of the support for nose surgery increases, it is desirable that the inner diameter be 3 mm to 8 mm in consideration of such a problem.

The wall thickness of the pleat of the tube 150 may be determined in consideration of the intranasal environment during treatment, depending on the inner diameter, outer diameter, and the material of the pleat, specifically, it is preferable that the wall thickness of the pleat of the tube 150 be set to a thickness that can withstand the pressure during treatment and can bend the tube 150.

Referring to Figs. 10 to 17, the support section 110 may be a first main body 121 and a second main body 123.

The first main body 121 is inserted into the nasal cavity 30 to support the external nose 20, and the second main body 123 rotates by being hinged to the first main body 121 by the hinge pin 125, and the tube 150 may be formed therein.

On end portion of the first main body 121 is inserted into the second main body 123, and the hinge pin 125 is coupled to the one end portion of the first main body 121, and the second main body 123 can rotate.

Referring to Figs. 10 and 11, the coupling between the first main body 121 and the second main body 123 may be performed by a hinge pin 125 so that receiving grooves are formed in the lengthwise direction of the second main body 123, and the one end portion of the first main body 121 is received in the receiving groves of the second main body 123. The second main body 123 relatively rotates with respect to the first main body 121 by the hinge coupling.

Meanwhile, referring to Figs. 13 and 14, the coupling between the first main body 121 and the second main body 123 may be performed by being hinged though the hinge pin 125 so that a receiving groove is formed only in a part of the second main body 123, and the one end portion of the first main body 121 is received inside the second main body 123.

Meanwhile, referring to Fig. 15, a first main stepped portion 122 and a second main stepped portion 124 are formed on each of the one surfaces of the first main body 122 and the second main body 123, and the second main body 123 may be hinged to the first main body 121 by the hinge pin 125 so as to rotate while the stepped

portions

122, 124 face each other.

When the first main body 121 and the second main body 123 are hinged, since it is possible to adjust an installation angle of the first main body 121 and the second main body 123, the one end of the tube 150 may be more easily located in the middle nasal meatus 34 for respiration during treatment.

Figs. 12 and 17 are operational state diagrams of the support for nose surgery according to several embodiments of the present invention.

Referring to Figs. 12 and 17, the second main body 123 of the support for nose surgery according to the present invention is rotated prior to treatment such that the tube 150 is formed at a fixed angle. Thereafter, the pleated tube formed at the end portion of the tube 150 is pulled out to extend the length of the tube 150 for respiration. Thereafter, the first main body 121 is inserted into the nose, and the pleated tube is bent as needed and is located so that the one end portion of the tube 150 of the second main body 123 faces the middle nasal meatus.

Figs. 18 and 19 are cross-sectional views showing a state during treatment of the support for nose surgery according to another embodiment of the present invention, and Figs. 20 and 21 are cross-sectional views showing a state during treatment of the support for nose surgery according to the modified example of another example of the present invention. Figs. 18 and 20 are cross-sectional views showing a state in which the support for nose surgery is inserted into the nasal cavity, and Figs. 19 and 21 are cross-sectional views showing a state in which liquid is supplied to the support for nose surgery and the volume is expanded.

Figs. 18 to Fig. 21 show the nose 10, the external nose 20, the nasal cavity 30, the superior nasal concha 31, the medium nasal concha 33, the middle nasal meatus 34, the inferior nasal concha 35, the support for nose surgery 100, the support section 110, the tube 150, and the respiration hole 155.

Referring to Figs. 18 and 20, the support section 110 is inserted into the nasal cavity 30 so as to be inclined upward in the direction from inferior nasal concha 35 to the superior nasal concha 31 during treatment, and the tube 150 for respiration is disposed so as to face the middle nasal concha 34.

Referring to Figs. 19 and 21, saline water or the like is injected into the support section 110 during treatment process, or blood generated in the treatment process is absorbed into the support section 110, and thus, the support section 110 expands. Thus, the support section 110 may function as a support by maintaining the shape of the nose, and if bleeding occurs, it may function as a hemostatic body that compresses the bleeding site and stops the bleeding.

On the other hand, the one end 151 of the tube 150 is positioned between the middle nasal concha 33 and the inferior nasal concha 35, and the tube 150 communicates with the middle nasal meatus 34. Thus, it is possible to prevent a phenomenon in which the air passage in the nasal cavity 30 is blocked by the support after treatment, whereby the patient experiences the respiration difficulty.

While the description has been made with reference to the embodiments of the present invention, it would be appreciated by those skilled in the art that from the spirit and regions of the present invention can be variously modified and changed within the scope that does not depart from the sprit and range of the invention set forth in the following claims.
