Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a device for collecting and suctioning stones in urological surgery. Background Technology

[0002] Ureteroscopic laser lithotripsy is an important surgical procedure, increasingly favored by urologists due to its minimally invasive nature. The procedure involves inserting a flexible ureteroscope sheath through the urethra, then guiding the ureteroscope into the kidney through the sheath. The laser then effectively fragments the stones. Because the sheath has a small diameter, continuous flushing with water is necessary while slowly withdrawing the ureteroscope to extract the stones into a suction bottle during negative pressure aspiration. Post-operative processing of the removed stones is crucial. However, the small stones mixed with a large amount of water in the suction bottle require manual filtration. Small stones easily adhere to the filter membrane, hindering filtration, and waste fluid splashing during filtration poses a risk of infection to medical staff.

[0003] Therefore, a device is needed that can easily filter and collect stones. Utility Model Content

The stone removal tube is installed on the side where the fixing tube is located.

[0008] Furthermore, the scraper is inclined, and the angle between the scraper and the connecting rod is greater than 90 degrees.

[0009] Furthermore, an electric push rod is installed on the outer surface of the filter pot, and the push rod of the electric push rod is connected to a connecting rod, with the push rod being parallel to the connecting rod.

[0010] Furthermore, the stone collecting bottle is connected to the first row of stone tubes and the second row of stone tubes via a third connecting pipe. The third connecting pipe is a Y-shaped flexible tube, with its first end connected to the first row of stone tubes, its second end connected to the second row of stone tubes, and its third end connected to the stone collecting bottle.

[0011] Furthermore, the stone collecting bottle is connected to an external negative pressure device, and a suction tube is connected to the stone collecting bottle, which is connected to the negative pressure device.

[0016] This invention features a first filter pot and a second filter pot. The first filter pot is used first for filtration, during which a scraping membrane structure cleans the surface of the filter membrane. When a significant amount of stones accumulates in the first filter pot, the second filter pot is opened and used before closing the first filter pot. This ensures that the negative pressure suction process is not interrupted and the stones are not affected during filtration. The stones accumulated in the first filter pot are then discharged into a stone collection bottle through a first stone discharge tube. The first and second filter pots can be used alternately, allowing for smooth filtration. The stone filtration is completed during the negative pressure suction process, saving time.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] A specific embodiment, as shown in the figure, represents a preferred embodiment of this utility model. A urological surgical stone collection and suction device mainly includes a water collection bottle 1, two filter jugs, a first connecting pipe 9, a second connecting pipe 2, and a stone collection bottle 5. Both the first connecting pipe 9 and the second connecting pipe 2 are Y-shaped flexible tubes. Each filter jug ​​has a connection port at both ends. The two filter jugs are designated as the first filter jug ​​and the second filter jug, and their structures are identical. The first end of the first connecting pipe 9 is connected to the patient's body, the second end of the first connecting pipe 9 is connected to the first connection port of the first filter jug, and the third end of the first connecting pipe 9 is connected to the first connection port of the second filter jug. A first valve 8 is installed on the second end of the first connecting pipe 9, and a second valve 1 is installed on the third end of the first connecting pipe 9. 0; The second connection port of the first filter jug ​​is connected to the first end of the second connecting pipe 2, the second connection port of the second filter jug ​​is connected to the second end of the second connecting pipe 2, the third end of the second connecting pipe 2 is connected to the water collection bottle 1, a third valve 4 is installed on the first end of the second connecting pipe 2, a fourth valve 15 is installed on the second end of the second connecting pipe 2, and the water collection bottle 1 is connected to an external negative pressure device through a negative pressure pipe 16; The first filter jug ​​is provided with a first stone discharge pipe 19, a fifth valve 20 is installed on the first stone discharge pipe 19, the second filter jug ​​is provided with a second stone discharge pipe 14, a sixth valve 13 is installed on the second stone discharge pipe 14, and the first stone discharge pipe 19 and the second stone discharge pipe 14 are detachably connected to the stone collection bottle 5.

[0024] In the specific implementation of this invention, medical staff open an external negative pressure device to suction the fluid mixed with stones from the patient's body. The negative pressure device used for suction in the medical field is an existing structure and will not be described in detail here. The fluid flows through the first connecting pipe 9. At this time, the first valve 8 and the third valve 4 are opened, and the second valve 10, the fourth valve 15, the fifth valve 20, and the sixth valve 13 are closed, allowing the fluid to flow from the second end of the first connecting pipe 9 into the first filter pot. The fluid is filtered through the first filter pot, leaving the stones inside. The filtered fluid then flows from the first end of the second connecting pipe 2 into the water collection bottle 1. When the stone content in the fluid remaining in the first filter pot increases, and the fluid becomes viscous, making filtration difficult, the first valve 8 is closed, and the second valve 10 and the fourth valve 15 are opened, allowing the fluid to enter the second filter pot for further filtration. At this point, because the first valve 8 is closed but the third valve 4 is not closed, liquid no longer enters the first filter pot. However, the liquid that previously flowed into the first filter pot can still be drawn out by the negative pressure, allowing as much liquid as possible to be drawn out, leaving the stones inside the first filter pot. Furthermore, the stone collection bottle 5 is connected to an external negative pressure device, and a suction tube is connected to the stone collection bottle 5. This suction tube is connected to the negative pressure device; this structure is existing and will not be described in detail here. After a period of time, the third valve 4 is closed, and the first stone discharge pipe 19 is opened. The negative pressure device draws the viscous liquid containing the stones from the first filter pot into the stone collection pot. This is because the first valve 8 and the third valve 4 are closed simultaneously, keeping the first filter pot in a closed state. The negative pressure device can draw out the viscous liquid containing the stones from the first filter pot without creating suction on the human body or the water collection bottle 1. When the viscous liquid containing the stones in the first filter pot is drawn out by the negative pressure device, some of the stones attached to the filter membrane 18 are also drawn out. The same operating steps are used to filter using the second filter pot. Because the liquid flowing in through the first connecting pipe must pass through the filter membrane before flowing out of the filter jug, which affects the outflow rate, the filter jug ​​is relatively large to hold a certain volume of liquid. The drawn-out liquid can temporarily remain in the filter jug ​​awaiting filtration, allowing sufficient time for filtration without affecting the continuous negative pressure that draws the body's fluids out. This invention uses two filter jugs for filtration without interrupting the process of expelling stones, thus improving the filtration efficiency.

[0025] When there are many stones, two filter jugs are used for filtration, but the filtration effect is still not very good. Further, the filter jug ​​is equipped with a filter membrane 18 and a scraping membrane structure. The surface of the filter membrane 18 is perpendicular to the length of the filter jug. The scraping membrane structure mainly includes a scraper and a connecting rod 11. The scraper is installed at the first end of the connecting rod 11, and a piston is ringed around the connecting rod 11. A fixing tube 12 is vertically installed on the side of the filter jug, and the connecting rod 11 passes through the fixing tube 12. The piston is slidably connected to the fixing tube 12 and does not detach from it. The second end of the connecting rod 11 is always outside the fixing tube 12. The scraper 17 is located inside the filter jug, on the side of the filter membrane closest to the body. The front side of the scraper 17 is in contact with the filter membrane 18. The stone-discharging tube is installed on the side where the fixing tube 12 is located. Because the second end of the connecting rod 11 is always outside the fixed tube, when the scraper 17 moves inside the filter jug ​​driven by the connecting rod 11, the connecting rod 11 will not detach from the fixed tube 12 due to the limiting effect of the scraper 17. Furthermore, the length of the fixed tube is greater than the diameter of the filter jug. When the connecting rod 11 slides inside the fixed tube 12, the sliding distance is less than the length of the fixed tube 12, ensuring that the piston mounted on the connecting rod 11 does not detach from the fixed tube 12. The piston mounted on the connecting rod 11 keeps the filter jug ​​sealed, preventing negative pressure suction and liquid overflow. The back-and-forth sliding of the connecting rod 11 within the fixed tube 12 allows the scraper 17 at the end of the connecting rod 11 to clean the stones adhering to the surface of the filter membrane 18. During filtration, the negative pressure device maintains a continuous negative pressure, and the liquid is continuously drawn outwards. After the scraper structure cleans the stones adhering to the surface of the filter membrane 18, the liquid continues to pass through the filter membrane 18, extending the continuous filtration time and improving the filtration effect. When the stone solution in the first filter pot becomes too viscous, resulting in poor filtration, the second filter pot is used for filtration. Simultaneously, the filter membrane in the second filter pot is cleaned using a scraper. Then, a negative pressure device is used to draw the viscous solution from the first filter pot through the first stone discharge tube 19 into the stone collection bottle 5. Alternating between the two filter pots better meets the needs of the entire filtration process.

[0026] Furthermore, the scraper 17 is inclined, and the angle between the scraper 17 and the connecting rod 11 is greater than 90 degrees, so that the upper surface of the scraper 17 is less likely to retain viscous liquid from the stones.

[0027] Furthermore, an electric push rod is installed on the outer surface of the filter pot. The push rod of the electric push rod is connected to the connecting rod 11, and the push rod is parallel to the connecting rod 11. The surface of the filter membrane 18 is cleaned by the electric push rod, which is more labor-saving.

[0028] Furthermore, the stone collecting bottle 5 is connected to the first stone-row tube 19 and the second stone-row tube 14 via a third connecting pipe. The third connecting pipe is a Y-shaped flexible tube, with its first end connected to the first stone-row tube 19, its second end connected to the second stone-row tube 14, and its third end connected to the stone collecting bottle 5. The stone collecting bottle 5 is simultaneously connected to two filter jugs via the third connecting pipe, facilitating the subsequent centralized treatment of the filtered viscous liquid containing stones.

[0029] Furthermore, the side wall of the stone collecting bottle 5 adopts a telescopic flexible hose structure, and the upper end of the stone collecting bottle 5 is provided with a bottle cap. The bottle cap is detachably connected to the bottle mouth of the stone collecting bottle 5, and the bottle cap is provided with an exhaust pipe 3. A one-way valve is installed inside the exhaust pipe 3, and the one-way valve opens from the inside of the bottle outward. At this time, the stone collecting bottle 5 is equivalent to a manual negative pressure device, which is existing technology and will not be described in detail here. By compressing the stone collecting bottle 5, the internal gas is discharged through the exhaust pipe 3, and by stretching it, the stone collecting bottle 5 unfolds to generate suction, thereby sucking out the viscous liquid of stones filtered from the two filter jugs, which is convenient to use.

[0030] Furthermore, the openings of the first stone-discharging tube 19 and the second stone-discharging tube 14 inside the filter pot are recessed and lower than the side wall of the filter pot, causing the viscous liquid of the filtered stones to accumulate at the openings.

[0031] Furthermore, the filter jug ​​includes a first body 6 and a second body 7, which are detachably connected to form a closed filter jug. The first body 6 of the first filter jug ​​is connected to the first end of the second connecting pipe 2, and the first body 6 of the second filter jug ​​is connected to the second end of the second connecting pipe 2. The filter membrane 18 is installed inside the first body 6, and the distance between the filter membrane 18 and the open end of the first body 6 is not zero. The first stone discharge pipe 19 and the second stone discharge pipe 14 are both installed inside the first body 6. During filtration, the filter jug ​​can be placed vertically so that the liquid can cover the entire filter membrane 18, resulting in a larger filtration area and better filtration effect. After the viscous liquid containing the stones is extracted, the filter can be opened. The remaining viscous liquid will remain inside the first chamber 6, above the filter membrane 18, facilitating collection and ensuring a more accurate measurement of the stones. The internal filter membrane 18 can also be replaced. The filter membrane 18 is detachably fixed inside the first chamber 6. A retaining ring is provided on the inner wall of the first chamber 6, and the filter membrane 18 is installed within a retaining ring. This retaining ring is slidably connected inside the first chamber 6 and abuts against the retaining ring. Furthermore, the opened filter canister is easy to clean and disinfect, and can be reused.

[0032] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
