Problems solved by technology

[0007] However, because the outer diameter of the existing occlusion device is larger than the inner diameter of the intended site of bronchial occlusion, it is grasped by the forceps on the front end side of the bronchoscope and transferred to the intended site of occlusion for indwelling, so its operation requires many years of experience and skilled technology
[0008] In addition, occluding devices are usually left in multiple places. When the indwelling of one occluding device is completed, the bronchoscope needs to be pulled out from the body each time, and then the indwelling device is grasped with forceps protruding from the front end of the bronchoscope to the outside, and performed again. The operation of inserting a bronchoscope into the body takes a long time to handle and places a heavy burden on the patient

no. 1 Embodiment approach

[0059] figure 1 It is a perspective view showing the first embodiment of the medical blocking device of the present invention, figure 2 to represent figure 1 A longitudinal sectional view of the medical occlusion device shown, Figure 3 ~ Figure 5 respectively for illustration figure 1 A diagram of the method of use of the medical occlusion device shown.

[0060] It should be noted that the following image 3 and Figure 4 In the illustration, the right side is referred to as "front end" and the left side is referred to as "basal end (rear end)".

[0061] The medical blocking device 1 shown in these figures is fixed (indwelled) in a bronchus to block the bronchi.

[0062] The medical occluding device 1 has a core 2 and a swelling part 3 provided (fixed) around the core 2 .

[0063] The core part 2 has a function of a reinforcing member that reinforces the swelling part 3 (medical occluding device 1 ). The core 2 is formed of a rod-shaped wire 21, which is linear in th...

no. 2 Embodiment approach

[0122] Image 6 It is a side view showing a second embodiment of the medical blocking device of the present invention.

[0123] Hereinafter, the second embodiment will be described, but the description will focus on the differences from the above-mentioned first embodiment, and the description of the same items will be omitted.

[0124] Such as Image 6 As shown, in the medical occluding device 1 of the second embodiment, the core 2 is formed of a coiled wire 21 .

[0125] In addition, the swelling portion 3 is provided in a coil shape along the wire 21 of the core 2 to cover the entire wire 21 (core 2 ). When the swelling part 3 is swollen, the gap between the swelling parts 3 disappears, and the bronchus is occluded.

[0126] The same effect as that of the above-mentioned first embodiment can be obtained by using the medical blocking device 1 .

[0127] In addition, in the medical occluding device 1, the contact area between the core 2 and the swollen portion 3 is large,...

no. 3 Embodiment approach

[0129] Figure 7 It is a side view showing a third embodiment of the medical blocking device of the present invention.

[0130] Hereinafter, the third embodiment will be described, but the description will focus on the differences from the above-mentioned first embodiment, and the description of the same matters will be omitted.

[0131] Such as Figure 7 As shown, in the medical occluding device 1 of the third embodiment, the core 2 is formed of a coiled wire 21 .

[0132] In addition, the swelling portion 3 is provided in a rod shape covering the entire wire material 21 of the core portion 2 .

[0133] Using the medical blocking device 1, the same effects as those of the above-mentioned first embodiment can be obtained.

[0134] In addition, in the medical occluding device 1, the contact area between the core 2 and the swollen portion 3 is large, whereby the adhesiveness between the core 2 and the swollen portion 3 is improved.

Abstract

A medical blocking tool includes a core section and a swelling section which is provided around the core section. The core section has a function of a reinforcing member reinforcing the swelling section. The core section is formed as a bar-shaped wire rod, and is formed in a linear shape. The swelling section is formed of a swelling material which is swelled (expanded) by absorbing a liquid thereinto so that the volume thereof is increased. The swelling section is adapted to be swelled until a bronchial tube is blocked while coming into close contact with the inner wall of the bronchial tube at a portion to be blocked (a blocking target portion) in the bronchial tube. The swelling section is formed along the wire rod of the core section 2, and is formed in a bar shape while coating the entire part of the wire rod (core section). The medical blocking tool is formed in a cylindrical shape.

Description

technical field [0001] The invention relates to a medical blocking device which is placed in the lumen of a living body and blocks the lumen of the living body. Background technique [0002] Emphysema is a lesion mainly caused by the inhalation of harmful substances produced by smoking, etc., and mainly destroying the peripheral respiratory tract and alveoli in a wide range. The formation of the lesion is chronically progressive, and the respiratory function of the patient who has developed the lesion is significantly hindered. [0003] The main treatment methods for patients with emphysema are roughly divided into medical treatment and surgical treatment. Medical treatment can alleviate the symptoms of patients, but it is difficult to prevent the progression of emphysema. [0004] In addition, surgical treatments include, for example, lung volume reduction surgery and lung transplantation, but both of these treatments require major surgery, and the burden on the patient is...
