Description

[0001] This application is a divisional application of Chinese patent application No. 201780097192.4, filed on September 27, 2017, entitled "Middle Otitis Treatment Device". Technical Field

[0002] This invention relates to a device for treating otitis media, and more specifically, to a device for treating otitis media that can more effectively treat otitis media. Background Technology

[0003] Otitis media is an inflammatory disease that occurs in the middle ear. Most cases resolve on their own, but in severe cases, treatment is necessary.

[0004] One treatment for otitis media is to insert a ventilator into the tympanic membrane. This is done by making an incision in the tympanic membrane and inserting the ventilator into the incision. The ventilator allows effusion caused by inflammation to drain and regulates the pressure between the middle and outer ear.

[0005] Devices for installing a ventilation tube inside the tympanic membrane typically have a tubular front end. During the process of cutting the tympanic membrane with the device, the ventilation tube is arranged in the front end of the device and secured by friction with the inner circumferential surface of the front end of the device or with the outer circumferential surface of a rod-shaped component arranged inside the front end.

[0006] However, since the friction between the ventilator and the inner circumferential surface of the front end of the device cannot reliably secure the ventilator, the ventilator may detach from the device before it is inserted into the incision of the tympanic membrane. Summary of the Invention

[0007] Technical issues

[0008] Therefore, the object of the present invention is to solve the aforementioned problems and to provide an otitis media treatment device that can reliably fix the ventilation tube to the otitis media treatment device for smooth treatment of otitis media.

[0009] The problems to be solved by the present invention are not limited to those described herein, and those skilled in the art will clearly understand other problems not mentioned based on the following description.

[0010] Technical solution

[0011] The objective is achieved by a otitis media treatment device for installing a ventilation tube according to the present invention, comprising: a cutting sheath having a tubular shape and an inner diameter greater than the outer diameter of the ventilation tube; and a suction tube configured to be movable relative to the cutting sheath within the cutting sheath along the length direction of the cutting sheath, and having an insertion unit having an outer diameter smaller than the inner diameter of the ventilation tube at a front end and a fixing unit extending along the front end direction of the insertion unit and having an outer diameter greater than the inner diameter of the ventilation tube.

[0012] On the outer peripheral surface of the suction tube, the mounting platform is preferably formed at a position in the rear end direction of the insertion unit.

[0013] The outer diameter of the suction tube is preferably formed to be the same as the inner diameter of the cutting sheath at the rear end direction of the insertion unit.

[0014] The front end of the cutting sheath is preferably formed into a sharp shape.

[0015] The front end of the cutting sheath is preferably formed in a spiral shape.

[0016] Beneficial effects

[0017] When treating otitis media using the otitis media treatment device according to the present invention, since the air tube cannot be easily separated from the device, it can prevent the treatment from being interrupted or the parts other than the parts to be treated from being damaged due to the separation of the air tube during the process of moving the device onto the tympanic membrane or cutting the tympanic membrane.

[0018] In addition, the tympanic membrane can be cut more easily. Attached Figure Description

[0022] Figure 4 (a)-(d) and Figure 5 (a)-(d) are illustrative figures relating to a method of using the otitis media treatment device according to the present invention. Detailed Implementation

[0023] In the following description, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0024] Figure 1 This shows an overall perspective view of the otitis media treatment device 1 according to the present invention. Figure 2 An exploded perspective view of the front end of the otitis media treatment device 1 according to the present invention is shown. Furthermore, Figure 3 A cross-sectional view of the front end of the otitis media treatment device is shown.

[0025] The otitis media treatment device 1 according to the present invention is mainly used to cut open the tympanic membrane and install the ventilation tube 2 on the incision of the tympanic membrane during the treatment of otitis media.

[0026] The otitis media treatment device 1 according to the present invention includes a cutting sheath 10 and a suction tube 20.

[0027] The cutting sleeve 10 forms the exterior of the front end of the otitis media treatment device 1 and is shaped as a long tube. The inner diameter of the cutting sleeve 10 is larger than the outer diameter of the ventilation tube 2, so the ventilation tube 2 can be inserted into the cutting sleeve 10. Furthermore, the tympanic membrane can be cut through the front end of the cutting sleeve 10.

[0028] A suction tube 20 is disposed inside the cutting sheath 10 and is formed into a long tubular shape. The suction tube 20 is movable relative to the cutting sheath 10 along its length, and its front end can protrude from or be inserted into the cutting sheath 10. The suction tube 20 is movable relative to the cutting sheath 10, but the relative position of the suction tube 20 and the cutting sheath 10 can also be changed by moving the cutting sheath 10. The suction tube 20 can also aspirate and remove effusion from the middle ear.

[0029] The front end of the suction tube 20 includes an insertion unit 21 and a fixing unit 22. The outer diameter of the insertion unit 21 is smaller than the inner diameter of the vent tube 2, and the fixing unit 22 extends along the front end of the insertion unit 21 with an outer diameter larger than the inner diameter of the vent tube 2. The front end of the suction tube 20 includes the insertion unit 21 and the fixing unit 22. That is, when the vent tube 2 is located inside the cutting sleeve 10, the vent tube 2 is fitted onto the front end of the suction tube 20, and because the outer diameter of the fixing unit 22 is larger than the inner diameter of the vent tube 2, the vent tube 2 can be prevented from separating from the insertion unit 21.

[0030] Thus, according to the otitis media treatment device 1 of the present invention, since the ventilation tube 2 cannot be easily separated from the device, it is possible to prevent the treatment from being interrupted or the parts other than the parts to be treated from being damaged due to the separation of the ventilation tube 2 during the process of moving the device onto the tympanic membrane or cutting the tympanic membrane with the cutting sheath 10.

[0031] The mounting platform 23 is preferably formed on the outer peripheral surface of the suction tube 20. The mounting platform 23 is formed to protrude from the rear end direction of the insertion unit 21.

[0032] Such a mounting bracket 23 can prevent the ventilation tube 2, which is mounted on the insertion unit 21, from moving towards the rear end of the insertion unit 21, thereby fixing the ventilation tube 2 at a certain position on the suction tube 20. Therefore, when the ventilation tube 2 is inserted into the incision of the tympanic membrane while moving the device, the ventilation tube 2 can be inserted into the correct position.

[0033] The outer diameter of the suction tube 20 can be configured to be the same as the inner diameter of the cutting sheath 10 at the rear end direction of the insertion unit 21.

[0034] In this case, when the suction tube 20 moves within the cutting sleeve 10, it will not wobble in the radial direction of the cutting sleeve 10 and can only move in the longitudinal direction of the cutting sleeve 10, thus preventing a decrease in the accuracy of controlling the suction tube 20.

[0035] If the outer diameter of the suction tube 20 is exactly the same as the inner diameter of the cutting sleeve 10, the suction tube 20 may have difficulty moving inside the cutting sleeve 10. Therefore, the outer diameter of the suction tube 20 is almost the same as the inner diameter of the cutting sleeve 10, but the outer diameter of the suction tube 20 is preferably formed to be slightly smaller than the inner diameter of the cutting sleeve 10.

[0036] The front end of the cutting sheath 10 is preferably formed into a sharp shape.

[0037] As described above, the cutting sheath 10 is used to cut the tympanic membrane. Therefore, if the front end is formed into a sharp shape, the tympanic membrane can be cut more easily.

[0038] The front end of the cutting sheath 10 can be formed into a spiral shape.

[0039] The tympanic membrane can be drilled through the front end of the spiral-shaped cutting sleeve 10, much like a drill bit. That is, if the cutting sleeve 10 is rotated while the front end of the cutting sleeve 10 is in contact with the tympanic membrane, a nearly circular cut can be formed on the tympanic membrane.

[0040] The otitis media treatment device 1 according to the present invention, in addition to the aforementioned components, also includes a handle 30 connected to the rear end of the cutting sheath 10 and the suction tube 20, a moving tool 40 for moving the suction tube 20 relative to the cutting sheath 10, and a suction tool (not shown) for giving the suction tube 20 suction force.

[0041] The method of using the otitis media treatment device 1 of the present invention, as described above, is as follows. Figure 4 (a)-(d) and Figure 5 (a)-(d) show illustrative diagrams regarding the method of using the otitis media treatment device according to the present invention. Figure 4 (a)-(d) represent the operating states of the otitis media treatment device during the preparation for treatment. Figure 5(a)-(d) represent the operating status of the otitis media treatment device during treatment.

[0042] like Figure 4 As shown in (a), the suction tube 20 is arranged inside the cutting sheath 10 in its basic state, and when the vent tube 2 is attached to the suction tube 20, it is connected by means of... Figure 4 (b) Operate the moving tool 40 as shown, so that the front end of the suction tube 20 protrudes outward from the cutting sheath 10. When the vent tube 2 is fixed to the suction tube 20, as shown... Figure 4 As shown in (c), the suction tube 20 is assembled onto the suction tube 20 until the front end of the vent tube 2 reaches the rear end of the fixing unit 22, thereby preventing the vent tube 2 from easily separating from the suction tube 20 by means of the fixing unit 22 having an outer diameter larger than the inner diameter of the vent tube 2. When the operation of the moving tool 40 is released, as... Figure 4 As shown in (d), when the suction tube 20 moves into the cutting sheath 10, the ventilation tube 2 also moves into the cutting sheath 10. This completes the treatment preparation process for the otitis media treatment device of the present invention.

[0043] When using the device with the airway tube 2 fixed for treatment, such as Figure 5 As shown in (a), the tympanic membrane 3 is first cut using the front end of the cutting sleeve 10. The front end of the cutting sleeve 10 can be formed into a sharp or spiral shape to facilitate cutting the tympanic membrane 3. The suction tube 20 and the ventilation tube 2 remain inside the cutting sleeve 10 to avoid interference with the operation when cutting the tympanic membrane 3. After cutting the tympanic membrane 3, as... Figure 5 As shown in (b), the cutting sleeve 10 is inserted into the incision. At this time, the suction tube 20 and the ventilation tube 2 located inside the cutting sleeve 10 are also inserted into the incision of the tympanic membrane 3.

[0044] In addition, by operating the moving tool 40, such as Figure 5 As shown in (c), the cutting sheath 10 is removed from the incision in the tympanic membrane 3, and the ventilator 2, which is fixed to the suction tube 20, is held in the position of the incision in the tympanic membrane 3. Exudate can be sucked in and removed by using the suction tube 20, which protrudes outward from the cutting sheath 10. Of the suction tube 20 and the ventilator 2, the outermost ventilator 2 contacts and is held in place by the tympanic membrane 3.

[0045] like Figure 5 As shown in (d), if the otitis media treatment device according to the present invention is retracted and removed from the tympanic membrane 3, the suction tube 20 and the ventilation tube 2 can be separated by the force of the ventilation tube 2 being held by the tympanic membrane 3. Figure 5As shown in (d), the ventilator 2 has portions 2a protruding at both ends along its length on the outer peripheral surface of the ventilator 2, through which the ventilator 2 can be more firmly fixed to the tympanic membrane 3. Through the ventilator 2 located on the tympanic membrane 3, residual or additionally generated exudate can be drained, and the pressure between the middle ear and the outer ear can be regulated.

[0046] The scope of protection of this invention is not limited to the embodiments described, but can be implemented in various forms within the scope of the appended claims. Without departing from the spirit of the invention as claimed in the claims, those skilled in the art will recognize that various modifications and improvements to the technical solutions of this invention should fall within the scope of protection defined by the claims.
