Problems solved by technology

[0002] Balloon dilatation is used to treat sinusitis. After a period of time, some patients have symptoms of sinus narrowing again, which affects the drainage of the sinus cavity, leads to recurrence of lesions, and affects the curative effect of the operation, thus requiring a second operation.
At the same time, in order to avoid the above-mentioned symptoms, patients need to be reexamined repeatedly, which will not only increase iatrogenic creation, but also increase the suffering of patients and increase the economic burden of patients

Embodiment 1

[0028] refer to figure 1 and figure 2 As shown, a sinus stent of the present invention, the stent is a cylindrical body 1, and the wall of the cylindrical body 1 is a mesh structure made of elastic material; the outer diameter of the cylindrical body 1 is 4 to 15mm, and the The length of the cylindrical body 1 is 6-20 mm. The mesh structure in this embodiment is braided by wires made of nickel-titanium memory alloy, and the diameter of the wires is 0.05-0.5 mm. Two types of 0.1 mm and 0.2 mm are preferred. At the same time, the mesh size of the mesh structure is 1mm2˜9mm2.

[0029] see picture Figure 5 and Figure 7 As shown, a special delivery device for a sinus stent of the present invention includes a strip-shaped control handle 2, and a long hole is provided along the length direction on the side wall of the control handle 2, and a sliding handle 3 is arranged in the long hole. The free end of the sliding handle 3 located in the control handle 2 is connected with a...

Embodiment 2

[0032] refer to image 3 and Figure 4 As shown, a sinus stent of the present invention has basically the same structure as that of Embodiment 1, the difference being that the cylindrical body 1 is composed of a support part 1a and a positioning part 1b arranged at both ends of the support part 1a, and the support part 1a and the positioning part The part 1b is an integral structure; the outer diameter of the supporting part 1a is 5-10mm, and the outer diameter of the positioning part 1b is 6-14mm. This structure can make the sinus stent less prone to displacement in the sinus ostium, and can further prolong the time for the sinus ostium to be narrowed again. Its use and positioning method are the same as in Embodiment 1.

Abstract

The invention discloses a paranasal sinus holder and a special conveying appliance thereof, which belong to the technical field of paranasal sinus dilation equipment. The invention has the technical points that the paranasal sinus holder is a tubular body; the tube wall of the tubular body is of a netted structure made of an elastic material; the conveying appliance comprises a control handle; the side wall of the control handle is provided with a slot hole; a sliding handle is arranged in the slot hole; the free end of the sliding handle, which is located in the control handle, is connected with a flexible outer sleeve; the free end of the flexible outer sleeve extends to the outside of the control handle; a flexible inner tube is movably sheathed in the flexible outer sleeve; one end of the flexible inner tube passes through the control handle and is communicated with the outside; and the other end of the flexible inner tube is matched with the flexible outer sleeve to form a containing cavity used for containing the compressed paranasal sinus holder. The invention aims to provide the paranasal sinus holder with a simple structure and a good service effect and the special conveying appliance with a compact structure and simplicity and convenience in operation. The paranasal sinus holder and the special conveying appliance thereof are used for paranasal sinus dilation.

Description

technical field [0001] The invention relates to an auxiliary device for sinus expansion, more specifically, a sinus support. The present invention also relates to a special delivery device for the above sinus stent. Background technique [0002] Balloon dilatation is used to treat sinusitis. After a period of time, some patients have symptoms of sinus narrowing again, which affects the drainage of the sinus cavity, leads to recurrence of lesions, and affects the curative effect of the operation, thus requiring a second operation. At the same time, in order to avoid the above-mentioned symptoms, patients need to be reexamined repeatedly, which will not only increase iatrogenic creation, but also increase the suffering of patients and increase the economic burden of patients. Contents of the invention [0003] The former purpose of the present invention is to provide a sinus support with simple structure and good use effect. [0004] The latter object of the present invent...
