Description

Technical Field

[0001] The invention relates to the technical field of bronchial occluders, in particular to a catheter-visible bronchial occluder. Background Art

[0002] Bronchial occluders are often used for single-lung ventilation and single-lung isolation during thoracotomy. Existing bronchial occluders require the cooperation of fiberoptic bronchoscopes to complete the placement of tubes to achieve single-lung ventilation and single-lung isolation. With the development and progress of science and technology, visual occluders have been maturely applied in clinical practice.

[0003] With regard to the existing related technologies, the inventors believe that the following defects often exist: sputum is a common secretion of the respiratory tract, and its production is closely related to pathological conditions such as inflammation and infection of the respiratory tract. The bronchial occluder is inserted into the bronchus, and sputum is produced by the bronchus. During the placement of the bronchial occluder, the presence of sputum often blocks the occluder, thereby seriously affecting the doctor's visualization operation, blocking the doctor's field of vision, making it impossible to clearly observe the structure in the bronchus, thereby affecting the accurate placement and positioning of the occluder, and also affecting the doctor's observation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention reduces the distance between the two middle blocks by folding the rotating arms. When the distance between the two middle blocks is reduced, the two sides of the sputum knife assembly are folded toward the middle. At this time, the distance between the sputum knife assemblies on both sides is reduced. At the same time, the distance between the sputum knife body 1 and the arm bar 2 on the sputum knife assembly is also reduced. The rotating arms are preliminarily folded, and then, the rotating arms on both sides are rotated upward to reduce the distance between the rotating arms on both sides. The folding frame is folded from a semicircle to a flat ellipse. At this time, the airbag ball and the airbag sheet are correspondingly flattened and stretched, and the entire occluder becomes a slender and narrow state. Then, the occluder is placed into the bronchus, which is more conducive to passing through the carina and entering the inside of the bronchus.

[0016] 2. In the present invention, the sputum knife assembly and the middle block are in a snap-on connection, and the connection process is as follows: align the T-slot 2 with the T-slot 1, and then insert the I-shaped card block into the inside of the T-slot 1 and the T-slot 2 on the same side. At this time, the connecting shaft and the sputum knife body 2 are snap-connected together, and the sputum knife body 2 is installed between the two middle blocks in a snap-on manner. In the later use, the sputum knife body 2 can be disassembled and replaced according to the usage situation, which is convenient for the use of the occluder.

[0017] 3. According to the present invention, when the occluder is blocked from view by sputum, the sputum will adhere to the airbag sheet, and the lifting block on one side will be pulled upward, driving the metal wire on the corresponding side to move upward, and at this time driving the flexible magnetic strip to rotate toward the corresponding side. While the flexible magnetic strip is rotating, since the flexible magnetic strip and the magnet strip are in a state of magnetic adsorption, the sputum knife assembly will rotate simultaneously with the flexible magnetic strip. When the sputum knife assembly rotates, the sputum knife body rotates along the outer wall surface of the airbag sheet, and the sputum knife body scrapes off the sputum adhered to the outer wall surface of the airbag sheet to prevent the sputum adhered to the outer wall surface of the folding frame from blocking the field of view of the flexible high-definition endoscope. Similarly, the metal wire on the other side is pulled to rotate the flexible magnetic strip toward the other side, so that both the left and right sides of the flexible magnetic strip can be rotated, and one flexible magnetic strip can perform a comprehensive sputum clearing operation on the airbag sheet.

[0018] 4. The present invention has drainage bevels on both sides of the sputum knife body. When the sputum knife body is used to scrape sputum, the sputum is concentrated on the drainage bevels on both sides of the sputum knife body. Since the drainage bevels are wide at the top and narrow at the bottom, when the sputum is located at a certain position, the sputum is guided by the drainage bevels to be concentrated at the narrow position below. After the sputum is concentrated and guided, it is pushed to the side, thereby improving the effect of clearing and isolating the sputum and preventing the sputum from blocking the flexible high-definition endoscope.

[0019] 5. In the present invention, LED lamp beads illuminate the inside of the bronchus, provide light brightness for the camera, and improve the clarity of the camera when shooting. At the same time, when the driving part drives the bending part to turn and move, the bending part will bend with the bellows, and the movement of the bellows will drive the airbag ball, folding frame and airbag sheet to move synchronously through the T-shaped connecting tube, so that they can move synchronously, avoiding the head of the camera being in different states when the camera is turned and adjusted, resulting in position deviation between the two, causing obstruction to the camera and affecting the doctor's field of vision.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figures 1 to 11 The present invention proposes a technical solution, a catheter-visible bronchial occluder, comprising: Tube end 1, an airbag ball 2 is installed at the head end of the tube end 1, an air injection tube 21 is fixedly installed on the outer wall of the tube end 1 by connection, and the air outlet end of the air injection tube 21 is located inside the airbag ball 2, a folding frame 3 is installed on the outer wall of the airbag ball 2, an airbag sheet 4 is installed on the folding frame 3, a flexible magnetic strip 5 is installed on the inner wall of the folding frame 3, and the flexible magnetic strip 5 is located between the opposite surfaces of the airbag ball 2 and the airbag sheet 4, metal wires 51 are installed on both sides of the flexible magnetic strip 5, and holes for the metal wires 51 to pass through are opened on both sides of the T-shaped connecting tube 13, a soft high-definition endoscope 6 is installed inside the tube end 1, and the soft high-definition endoscope 6 is an existing mature technology, so it will not be described in detail, the airbag ball 2 and the airbag sheet 4 are made of transparent materials; The folding frame 3 includes two middle blocks 31 installed on both sides of the outer wall of the airbag ball 2, and the flexible magnetic strip 5 is fixed between the two middle blocks 31. A rotating arm 32 is rotatably installed between the two sides of the two middle blocks 31, and a sputum knife assembly 33 is rotatably installed between the opposite ends of the two middle blocks 31, and the cleaning end of the sputum knife assembly 33 is in contact with the outer wall surface of the airbag sheet 4. The folding frame 3 has two shape states. The shape of the folding frame 3 is changed by rotating and folding the rotating arm 32 and the sputum knife assembly 33. One is a semicircular state, such as Figure 1 As shown, the other is a flat elliptical state after folding.

[0024] like Figure 4 By folding the rotating arm 32, the distance between the two middle blocks 31 is reduced. When the distance between the two middle blocks 31 is reduced, the two sides of the sputum knife assembly 33 are folded toward the middle. At this time, the distance between the sputum knife assemblies 33 on both sides is reduced. At the same time, the distance between the sputum knife body 1 331 and the arm bar 2 322 on the sputum knife assembly 33 is also reduced. The rotating arm 32 is preliminarily folded, and then, there is a rotation connection between the middle block 31 and the rotating arm 32, and the rotating arms 32 on both sides are rotated upward to reduce the distance between the rotating arms 32 on both sides. The folding frame 3 is folded from a semicircle to a flat ellipse. At this time, the airbag ball 2 and the airbag sheet 4 are also flattened and stretched accordingly, and the entire occluder becomes a slender and narrow state. Then, the occluder is placed into the bronchus, which is more conducive to passing through the carina into the interior of the bronchus.

[0025] The tube end 1 includes an outer protective tube 11, and a bellows 12 is installed at one end of the outer protective tube 11 close to the folding frame 3, and a T-shaped connecting tube 13 connected to the inside of the airbag ball 2 is installed at one end of the bellows 12 away from the outer protective tube 11. The flexible high-definition endoscope 6 includes a driving part 61 installed inside the outer protective tube 11, and the driving part 61 is connected to the host through a wire. A bending part 62 is installed at one end of the driving part 61 close to the bellows 12, and the bending part 62 is fixed inside the bellows 12. A camera 63 is arranged on the bending part 62. When the driving part 61 drives the bending part 62 to turn and move, the bending part 62 will carry the bellows 12. The bellows 12 is bent, and the movement of the bellows 12 drives the airbag ball 2, the folding frame 3 and the airbag sheet 4 to move synchronously through the T-type connecting tube 13, so that they can move synchronously to avoid the head of the camera 63 being in different states when the camera 63 is turned and adjusted, and there is a position deviation between the two, which blocks the camera 63 and affects the doctor's field of vision. A circle of LED lamp beads 64 equidistantly distributed with the camera 63 as the center point is installed at the end of the bending part 62 away from the driving part 61. The LED lamp beads 64 are illuminated inside the bronchus to provide light brightness to the camera 63, thereby improving the clarity of the camera 63 when shooting.

[0026] The middle block 31 and the airbag ball 2 are fixedly connected together by a connecting piece, and the connecting piece is memory metal or medical gelatin. Gelatin is a natural protein that can dissolve quickly at body temperature. It dissolves within a few minutes to a few hours when exposed to body temperature.

[0027] The sputum knife assembly 33 includes a sputum knife body 1 331 and a sputum knife body 2 332, and the sputum knife body 1 331 and the sputum knife body 2 332 are respectively rotatably mounted on the two middle blocks 31, and the sputum knife body 1 331 and the sputum knife body 2 332 are inlaid with a magnet strip 334 on one side facing the airbag ball 2, and the magnet strip 334 and the opposite surface of the flexible magnetic strip 5 are in a magnetic adsorption state, and the sputum knife body 2 332 is installed with two fixed blocks 335 on the side close to the sputum knife body 1 331, and an installation shaft 336 is rotatably mounted between the opposite surfaces of the two fixed blocks 335 through a bearing, and a rotating block 337 is sleeved on the installation shaft 336, and the rotating block 337 is fixed on the side of the sputum knife body 1 331 close to the sputum knife body 2 332.

[0028] When the occluder is blocked from view by sputum, the sputum will adhere to the airbag sheet 4, and the lifting block 515 on one side will be pulled upward, driving the metal wire 51 on the corresponding side to move upward, and at this time driving the flexible magnetic strip 5 to rotate toward the corresponding side. While the flexible magnetic strip 5 is rotating, since the flexible magnetic strip 5 and the magnet strip 334 are in a state of magnetic adsorption, the sputum knife assembly 33 will rotate simultaneously with the flexible magnetic strip 5. When the sputum knife assembly 33 is rotating, the sputum knife body 331 rotates along the outer wall surface of the airbag sheet 4, and the sputum knife body 331 scrapes off the sputum adhered to the outer wall surface of the airbag sheet 4 to prevent the sputum adhered to the outer wall surface of the folding frame 3 from blocking the field of view of the flexible high-definition endoscope 6. Similarly, the metal wire 51 on the other side is pulled to rotate the flexible magnetic strip 5 to the other side, so that both the left and right sides of the flexible magnetic strip 5 can be rotated, and one flexible magnetic strip 5 can perform a comprehensive sputum clearing operation on the airbag sheet 4.

[0029] A connecting shaft 312 is rotatably mounted on the outward end surface of the middle block 31 through a bearing, and arc-shaped connecting blocks 333 are mounted on the tops of the sputum knife body 1 331 and the sputum knife body 2 332, and the arc-shaped connecting block 333 is clamped and connected with the connecting shaft 312, a T-slot 1 3121 is opened outwardly of the connecting shaft 312, a T-slot 2 3331 is opened outwardly of the sputum knife assembly 33, and an I-shaped clamping block 338 is clamped between the T-slot 1 3121 and the T-slot 2 3331 on the same side.

[0030] The sputum knife assembly 33 is connected to the middle block 31 in a snap-on connection, and the connection process is as follows: Align the T-slot 2 3331 with the T-slot 1 3121, and then insert the I-shaped block 338 into the T-slot 1 3121 and the T-slot 2 3331 on the same side. At this time, clamp the connecting shaft 312 and the sputum knife body 2 332 together, and install the sputum knife body 2 332 between the two middle blocks 31 in a clamping manner. In the later use, the sputum knife body 2 332 can be disassembled and replaced according to the usage, which is convenient for the use of the occluder.

[0031] Both sides of the sputum knife body 1 331 and the sputum knife body 2 332 are provided with drainage bevels 339, and the drainage bevels 339 are wide at the top and narrow at the bottom. The drainage bevels 339 on both sides of the sputum knife body 2 332 are set, when the sputum knife body 2 332 scrapes sputum, the sputum is concentrated on the drainage bevels 339 on both sides of the sputum knife body 2 332. Since the drainage bevels 339 are in a shape of wide at the top and narrow at the bottom, when the sputum is located at 39, the sputum is guided by the drainage bevels 339 to be concentrated in the narrow position below, and the sputum is pushed to the side after being concentrated and guided, thereby improving the clearing and isolation effect of the sputum and preventing the sputum from blocking the flexible high-definition endoscope 6.

[0032] When the pull force on the lifting block 515 is released, the flexible magnetic strip 55 is pulled back to the middle under the elastic reset action of the spring 513, so that the flexible magnetic strip 55 is automatically reset.

[0033] The rotating arm 32 includes an arm bar 1 321 and an arm bar 2 322 . The opposite ends of the arm bar 1 321 and the arm bar 2 322 are rotationally connected together, and the opposite ends of the arm bar 1 321 and the arm bar 2 322 are rotationally connected to the two middle blocks 31 respectively.

[0034] A rotating connecting block 324 is fixedly installed between the opposite surfaces of the arm bar 1 321 and the sputum knife body 2 332, and a rotating shaft 2 325 is rotatably installed between the two rotating connecting blocks 324 through a bearing. The arm bar 1 321 and the arm bar 2 322 are rotationally connected through the rotating shaft 2 325. Through the rotation connection between the two rotating connecting blocks 324 and the rotating shaft 2 325, the arm bar 1 321 and the arm bar 2 322 are rotationally connected together, thereby realizing the folding of the rotating arm 32.

[0035] Both sides of the middle block 31 are equipped with convex connecting blocks 1 311, and the two opposite ends of the arm bar 1 321 and the arm bar 2 322 are equipped with convex connecting blocks 2 323. A rotating shaft 1 313 is rotatably installed between the convex connecting block 2 323 and the convex connecting block 1 311 on the same side through a bearing. The middle block 31 and the arm bar 1 321, and the middle block 31 and the arm bar 2 322 are rotatably connected through the rotating shaft 1 313. The rotating arm 32 and the middle block 31 are connected through the convex connecting block 1 311 and the rotating shaft 1 The cooperation between 313 and the convex connecting block 323 enables the middle block 31 and the rotating arm 32 to be rotatably installed on one side, so that the rotating arm 32 can be rotated relative to the middle block 31, and the sputum knife body 1 331 and the sputum knife body 2 332 can be rotated through the cooperation between the fixed block 335, the installation shaft 336 and the rotating block 337. When the arm bar 1 321 and the arm bar 2 322 are rotated and folded, the sputum knife body 1 331 and the sputum knife body 2 332 can be linked to be folded and stored.

[0036] The working principle of the present invention is: When in use, when the patient's bronchus begins above the carina, the bronchi on both sides are asymmetrical, with one side larger than the other. At this time, the folding frame 3 in a semicircular state is folded and deformed to become flat. The process is as follows: like Figure 4 , by folding the rotating arm 32, the distance between the two middle blocks 31 is reduced. When the distance between the two middle blocks 31 is reduced, the two sides of the sputum knife assembly 33 are folded toward the middle. At this time, the distance between the sputum knife assemblies 33 on both sides is reduced. At the same time, the distance between the sputum knife body 1 331 and the arm bar 2 322 on the sputum knife assembly 33 is also reduced. The rotating arm 32 is preliminarily folded, and then, there is a rotation connection between the middle block 31 and the rotating arm 32, and the rotating arms 32 on both sides are rotated upward to reduce the distance between the rotating arms 32 on both sides. The folding frame 3 is folded from a semicircle to a flat ellipse. At this time, the airbag ball 2 and the airbag sheet 4 are also flattened and stretched accordingly, and the entire occluder becomes a slender and narrow state. Then, the occluder is placed into the bronchus, which is more conducive to passing through the carina and entering the interior of the bronchus; When the flat airbag ball 2, the folding frame 3 and the airbag sheet 4 enter the bronchus, the airbag ball 2 is inflated through the air injection tube 21, so that the airbag ball 2 is inflated and expanded, the folding frame 3 and the airbag sheet 4 are expanded and restored, and the head is blocked in the bronchus for fixation; When the occluder is blocked from view by sputum, the sputum will adhere to the airbag sheet 4, and the lifting block 515 on one side will be pulled upward, driving the metal wire 51 on the corresponding side to move upward, and at this time driving the flexible magnetic strip 5 to rotate toward the corresponding side. While the flexible magnetic strip 5 is rotating, since the flexible magnetic strip 5 and the magnet strip 334 are in a state of magnetic adsorption, the sputum knife assembly 33 will rotate simultaneously with the flexible magnetic strip 5. When the sputum knife assembly 33 is rotating, the sputum knife body 331 rotates along the outer wall surface of the airbag sheet 4, and the sputum knife body 331 scrapes off the sputum adhered to the outer wall surface of the airbag sheet 4 to prevent the sputum adhered to the outer wall surface of the folding frame 3 from blocking the field of view of the flexible high-definition endoscope 6. Similarly, the metal wire 51 on the other side is pulled to rotate the flexible magnetic strip 5 to the other side, so that both the left and right sides of the flexible magnetic strip 5 can be rotated, and one flexible magnetic strip 5 can perform a comprehensive sputum clearing operation on the airbag sheet 4.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein.
