Description

Technical Field

[0001] This invention specifically relates to a device for cleaning tubing after endoscopy. Background Technology

[0002] Endoscopes are widely used in minimally invasive surgery. Their various tubing systems (such as working channels and suction tubes) retain blood, tissue fluid, and other contaminants post-surgery, requiring thorough cleaning and disinfection. Currently, cleaning the inner lining of these long, thin, and flexible tubing systems presents the following main technical challenges: First, traditional manual scrubbing methods are inefficient and produce uneven results. Operators use long-handled brushes to scrub single points in a reciprocating rotation, which is not only time-consuming and labor-intensive, but also difficult to adapt to the entire pipe wall due to the fixed brush head size, easily creating blind spots in cleaning, and is particularly ineffective at cleaning bends and distant parts of the pipe.

[0003] Secondly, brushing devices using a single power source have inherent drawbacks. For example, using a long, flexible shaft to drive a single brush head to rotate into the pipe from one end has significant disadvantages: 1) Severe torque transmission attenuation: When the flexible shaft rotates in a long, winding pipe, the friction is high, resulting in a significant decrease in the effective torque transmitted to the far end of the brush head, leading to weak brushing; 2) Brush head jamming: The insufficient rigidity of the flexible shaft makes it prone to deformation when encountering resistance or pipe bends, causing the brush head to get stuck inside the pipe, making it difficult to advance or retract, posing a risk of damaging the pipe or equipment; 3) Low cleaning efficiency: Single-point brushing requires the brush head to traverse the entire length of the pipe, making it impossible to clean multiple sections simultaneously, resulting in a long overall cleaning cycle.

[0004] In addition, some existing solutions that attempt to use multiple brush heads are often structurally complex, requiring independent drive or control mechanisms for each brush head. This results in bulky and costly devices, and makes it difficult to achieve precise and synchronized movement of multiple brush heads, thus compromising the uniformity and coordination of cleaning. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide a cleaning device for tubing after endoscopy. Therefore, there is an urgent need in the art for a device that can overcome the above-mentioned defects and achieve efficient, comprehensive, reliable and easy-to-operate cleaning of tubing after endoscopy.

[0006] To achieve the above objectives, the present invention provides a post-endoscopic tubing cleaning device, comprising: A guide tube can be inserted into the endoscope tubing to be cleaned, and the axial length of the guide tube is greater than the length of the endoscope tubing. At least two scrubbing assemblies are arranged axially spaced along the guide tube and are rotatably fitted onto the outside of the guide tube, allowing them to be inserted into the endoscope tubing along with the guide tube; each scrubbing assembly is configured to expand radially upon rotation until its outer peripheral surface contacts the inner wall of the endoscope tubing; and A rotary drive mechanism, which is connected in drive to all the washing components, is used to synchronously drive all the washing components to rotate.

[0007] The scrubbing assembly includes: A bushing, which is rotatably mounted to the outer wall of the guide tube via a first bearing; An internal gear is rotatably mounted on the inner wall of the guide tube via a second bearing and is connected to the rotary drive mechanism for transmission. A first magnetic component and a second magnetic component are provided. The first magnetic component is embedded in the bushing, and the second magnetic component is embedded in the internal gear. The magnetic properties of the first magnetic component and the second magnetic component are opposite, so that the rotation of the internal gear can drive the bushing to rotate synchronously through magnetic coupling. At least one cantilever arm, the top of which is hinged to the outer wall of the bushing; and The brush head is fixedly installed at the bottom end of the suspension arm; When the bushing rotates, the suspension arm swings outward under the action of centrifugal force, causing the brush head to generate radial expansion.

[0008] Furthermore, an elastic reset element is connected between the suspension arm and the bushing, and the elastic reset element is configured to pull the suspension arm back to the initial retracted position when the bushing stops rotating.

[0009] Furthermore, the brush head includes a mounting base and bristles, the mounting base being detachably connected to the bottom end of the suspension arm, and the bristles being embedded in the outer surface of the mounting base.

[0010] Furthermore, the rotary drive mechanism includes: A drive shaft is rotatably disposed within the internal cavity of the guide tube; The driving gear is fixedly mounted on the drive shaft. Both the driving gear and the internal gear are bevel gears, and the driving gear meshes with the internal gear to transmit the rotational power of the drive shaft to the internal gear. At least one helical blade, fixed to the outer periphery of the drive shaft; and A flushing fluid supply unit is configured to supply an impinging fluid flow to the helical blades to drive the drive shaft to rotate.

[0011] Furthermore, the flushing fluid supply unit includes: A liquid supply pipe is disposed within the guide pipe, and its wall has multiple water outlet holes, the spray direction of which is aligned with the spiral blades; and A high-pressure fluid interface is located at the end of the supply pipe and is used to connect to an external high-pressure fluid source.

[0012] Furthermore, the external high-pressure fluid source is configured to supply flushing fluid to the supply pipe in a pulsed intermittent manner.

[0013] Furthermore, it also includes a helical spring, the inner end of which is fixedly connected to the guide tube, and its outer end is drivenly connected to the bushing.

[0014] Furthermore, it also includes an axial reciprocating drive mechanism, which is drivenly connected to the guide tube and is used to drive the guide tube to perform intermittent reciprocating motion along its axial direction.

[0015] Furthermore, the axial reciprocating drive mechanism includes: A support plate, which is fixedly connected to the proximal end of the guide tube; A guide plate, which is slidably fitted onto the guide tube; An elastic support member is connected between the guide plate and the support plate; A cam, rotatably mounted on the guide plate; and A rotary power component, used to drive the cam to rotate; During rotation, the cam's protrusion periodically pushes against the support plate to overcome the elastic force of the elastic support member, thereby driving the guide tube to produce axial displacement.

[0016] The beneficial effects of this invention are: The above-mentioned endoscopy postoperative tubing cleaning device has at least the following advantages: 1. By setting up washing components spaced apart along the axial direction of the guide tube and using a rotary drive mechanism to synchronously drive all washing components to rotate, the device can simultaneously wash different sections of the tubing after insertion. This fundamentally changes the traditional single-point washing mode that must traverse the entire length, increasing cleaning efficiency several times over, and is particularly suitable for long endoscopic tubing.

[0017] 2. Each scrubbing component is constructed to expand radially upon rotation until it comes into close contact with the inner wall of the pipe. This design allows the scrubbing surface to adaptively conform to the pipe wall, providing uniform scrubbing pressure regardless of minute variations in pipe diameter. Multiple such components are spaced apart to ensure effective coverage of the entire inner wall of the pipe from proximal to distal, eliminating blind spots that are difficult to avoid with manual scrubbing or single-brush head cleaning.

[0018] 3. This solution abandons the complex design of equipping each brush head with an independent drive source, and adopts a single rotary drive mechanism to synchronously drive all components through a transmission system within the guide tube. This not only simplifies the overall structure and reduces manufacturing costs, but also avoids problems such as asynchrony and interference that may occur with multiple power sources. The guide tube, as a rigid or semi-rigid carrier, provides stable support and a movement track for the washing components, ensuring the reliability and stability of power transmission.

[0021] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention; therefore, the invention is not limited to the specific embodiments disclosed below.

[0022] Please see Figures 1 to 6 The present invention provides a post-endoscopic tubing cleaning device, including a guide tube 100, at least two cleaning components 200 and a rotary drive mechanism 300.

[0023] The guide tube 100 is a slender, rigid or semi-rigid tube, the length of which must be greater than or equal to the length of the endoscope tubing to be cleaned (such as the working channel tube or suction tube). This length design ensures that the guide tube 100 can completely pass through the entire tubing to be cleaned, thereby allowing the scrubbing assembly 200 carried on it to be delivered to any position inside the tubing, achieving full coverage of the tubing. The diameter of the guide tube 100 is much smaller than the inner diameter of the tubing to facilitate smooth insertion and leave sufficient space for the scrubbing assembly 200 to operate.

[0024] The scrubbing assemblies 200 are disposed outside the guide tube 100 and arranged at certain intervals along its axial direction. These scrubbing assemblies 200 are rotatably fitted onto the guide tube 100. This means that they can rotate freely about the axis of the guide tube 100, but cannot move arbitrarily along the axial direction of the guide tube 100 (or can only move within a set range). When the operator inserts the guide tube 100 into the endoscope tubing, all the scrubbing assemblies 200 are also brought into the tubing. Each scrubbing assembly 200 is designed to have a special operating state: radial expansion. In a stationary or low-speed state, its size is small, making insertion easy; when driven to rotate at high speed, it expands outward due to a specific mechanical structure (such as centrifugal force), allowing its outer peripheral surface (i.e., the scrubbing surface) to tightly abut and adhere to the inner wall of the tubing.

[0025] The rotary drive mechanism 300 is the core component providing power. It is connected to all the washing components 200 via a transmission system (which can be mechanical, magnetic, or other methods). When this mechanism operates, it synchronously drives all the washing components 200 to rotate together. This synchronous rotation design allows multiple washing components 200 to simultaneously clean different sections of the pipeline, greatly improving cleaning efficiency and avoiding the cumbersome operation and time wastage associated with driving each component individually.

[0026] This device, with its structure of "100 guide tubes + multiple sets of radially expandable washing components + synchronous rotation drive," achieves efficient, one-time, full-coverage mechanical cleaning of long and thin endoscope tubing. It overcomes the problems of torque transmission attenuation, brush head jamming, and low efficiency of single-point washing found in traditional long flexible shaft brushing.

[0027] In this embodiment, each washing assembly 200 is mainly composed of the following components: Bushing 210 and internal gear 220: Bushing 210 is mounted on the outer wall of guide tube 100 via a first bearing (such as a miniature deep groove ball bearing), allowing it to rotate freely relative to guide tube 100. Internal gear 220 is mounted on the inner wall of guide tube 100 (i.e., in an annular space machined inside the guide tube 100 or supported by a bracket) via a second bearing, with its teeth facing inwards from guide tube 100. Internal gear 220 is connected to the subsequent rotary drive mechanism 300 to receive power.

[0028] A first magnetic element 230 (such as a set of permanent magnets) is embedded in the inner ring of the bushing 210, and a second magnetic element 240 (also a permanent magnet) is embedded in the corresponding position on the outer ring of the internal gear 220. The magnetic poles of the two elements are opposite (N pole to S pole), generating a magnetic force that attracts each other. Since the wall of the guide tube 100 is made of a non-magnetic material (such as medical stainless steel or polymer material), magnetic lines of force can pass through it. When the rotary drive mechanism 300 drives the internal gear 220 to rotate, the strong magnetic attraction between these two magnetic elements allows the rotation of the internal gear 220 to drive the bushing 210 to rotate synchronously and without contact. This magnetic coupling transmission method transmits power from the inside of the guide tube 100 to the outside without requiring complex through-hole mechanical transmission holes in the wall of the guide tube 100. This ensures the structural integrity, sealing, and rigidity of the guide tube 100 and completely avoids the problem of cleaning fluid seeping into the interior through transmission gaps, causing contamination or corrosion.

[0029] Suspension arms 250 and brush heads 260: At least two (usually 3-4, evenly distributed circumferentially) suspension arms 250 are hinged to the outer wall of the bushing 210. Brush heads 260 are fixedly installed at the bottom end of the suspension arms 250. When the bushing 210 is driven to rotate at high speed, the hinged suspension arms 250 and brush heads 260 will be thrown outward under the action of centrifugal force, swinging outward around the hinge point, like an umbrella being opened. This swinging action directly causes the brush head 260 to move away from the central axis of the guide tube 100, that is, to generate radial expansion, until the outer surface of the brush head 260 (i.e., the bristles) is in close contact with the inner wall of the tube.

[0030] Furthermore, an elastic reset element 270 is connected between the suspension arm 250 and the bushing 210. The elastic reset element 270 is configured to pull the suspension arm 250 back to the initial retracted position when the bushing 210 stops rotating.

[0031] During the cleaning operation, the rotary drive mechanism 300 drives the drive bushing 210 to rotate at high speed. Centrifugal force overcomes the tension of the elastic reset element 270, causing the suspension arm 250 to swing outward to the working position (radial expansion). When cleaning is completed and rotation stops, the centrifugal force disappears. At this time, the elastic potential energy stored in the elastic reset element 270 is released, generating a pull force that pulls the outwardly swinging suspension arm 250 back, causing the brush head 260 to retract to the initial retracted position that is close to the outer wall of the guide tube 100.

[0032] This design minimizes the radial dimension of the entire device when it is folded up, making it very smooth for the guide tube 100 to withdraw from the pipeline carrying the brush assembly 200, greatly reducing the risk of the brush head 260 being damaged due to jamming or left in the pipeline. It also facilitates the storage and maintenance of the device.

[0033] In this embodiment, the brush head 260 adopts a modular design, consisting of a mounting base and brush bristles.

[0034] Mounting base: Typically made of medical-grade plastic or silicone, it features a slot, thread, or quick-connect fitting on its upper part for detachable connection to the bottom of the suspension arm 250. This design allows for quick replacement of brush heads 260 of different sizes or materials depending on cleaning needs (such as pipe inner diameter, type of contaminants).

[0035] Bristles: Densely embedded (i.e., fixed by processes such as tufting or inlay) on the outer surface of the mounting base. The bristle material can be nylon, polyester, or softer silicone filaments to adapt to different tube wall materials (such as PTFE coating), ensuring cleaning power while preventing scratches.

[0036] In this embodiment, the rotary drive mechanism 300 includes: Drive shaft 310, helical blades 330, and drive gear 320: A drive shaft 310, coaxial with the guide tube 100, is disposed within the internal cavity of the guide tube 100. The drive shaft 310 is supported by bearings at both ends and can rotate freely. At least one section of helical blades 330 (similar to the impeller or turbine of a water turbine) is fixedly mounted on the outer circumference of the drive shaft 310. The drive gear 320 is fixedly sleeved on the drive shaft 310. Both the drive gear 320 and the internal gear 220 are bevel gears, and the drive gear 320 meshes with the internal gear 220, enabling the rotational power of the drive shaft 310 to be transmitted to the internal gear 220. Rinse fluid supply unit 340 and power generation principle: This unit is responsible for introducing high-pressure rinsing fluid (such as enzyme washing solution or disinfectant) into the guide pipe 100. When the high-pressure rinsing fluid flows through the helical blades 330, the impact force of the fluid flow acts on the curved surface or inclination angle of the blades, generating a tangential force that drives the helical blades 330 to rotate. This principle is the same as that of a hydraulic turbine. Thus, the kinetic energy of the fluid is directly converted into the rotational mechanical energy of the drive shaft 310. This achieves integrated energy utilization; the rinsing fluid is not only used for final rinsing, but its energy during its forward movement is also recovered for driving the brushing process.

[0037] In this embodiment, the flushing fluid supply unit 340 includes a fluid supply pipe 341 and a high-pressure fluid interface.

[0038] Liquid supply pipe 341: This is typically a thin tube fixed to the inner wall of guide pipe 100 or coaxial with drive shaft 310 but not rotating. One or more water outlet holes 342 are precisely formed on its wall, directly opposite each spiral blade 330. The jet direction of these water outlet holes 342 is precisely calculated to ensure that the ejected high-pressure liquid stream impacts the force-bearing surface of the spiral blade 330 at the optimal angle, thereby maximizing energy conversion efficiency.

[0039] High-pressure fluid interface: Located at the end of the supply tubing 341 near the proximal end of the guide tube 100 (i.e., the end held by the operator). This interface is typically a standard Luer connector or quick-connect fitting for easy connection to an external high-pressure fluid source, such as the outlet of a cleaning and disinfection machine in a hospital central supply room, or a manual high-pressure source such as a large-capacity syringe.

[0040] Preferably, an external high-pressure fluid source supplies flushing fluid to the supply pipe 341 in a pulsed intermittent manner.

[0041] This means that the flushing fluid is not a continuous, steady stream of water, but rather sprayed in an intermittent or pulsed manner. This can be achieved, for example, by using an external pulse pump or by manually and rhythmically squeezing a syringe. When a high-pressure pulse of fluid impacts the helical blades 330, the drive shaft 310 receives a sudden increase in rotational torque, causing it to accelerate. During the intervals between two pulses, the drive shaft 310 continues to rotate due to inertia, although the speed may decrease slightly.

[0042] The pulsed supply produces several positive effects: First, the pulsed impact generates stronger instantaneous torque, helping to overcome the static friction between the brush head 260 and stubborn stains, making the brushing process more effective. Second, the periodic fluctuations in rotational speed caused by the pulses give the brush head 260 a "vibration" effect on the pipe wall, which is more effective at removing deposits than uniform rotation. Third, the intermittent high-pressure rinsing is also more effective at "vibrating" loosened contaminants out of the pipe cavity, preventing them from redepositing. This is equivalent to adding the effect of fluid pulsed cleaning to mechanical brushing.

[0043] In a preferred embodiment, a key auxiliary element—a helical spring 400—is added to the rotary drive mechanism 300. The helical spring 400 is sleeved on the outside of the guide tube 100, and the inner end of the spring (the end near the proximal end of the guide tube 100) is fixed to the guide tube 100 by a retaining ring or pin. The outer end of the spring is linked to the bushing 210 of the washing assembly 200 via a connector (e.g., inserted into a hole on the side of the bushing 210).

[0044] When the rotary drive mechanism 300 starts working, power is transmitted from the drive shaft 310 to the internal gear 220, and then to the bushing 210 through magnetic coupling. This drives the shaft to rotate. The spiral blades 330 store torsional force. When liquid is sprayed out of the liquid supply pipe 341, the flushing force of the spiral blades 330 is released, and the power transmission of the internal gear 220 disappears. Under the action of the negative force of the spiral blades 330, the bushing 210 is driven to rotate in the opposite direction, which in turn drives the scrubbing assembly 200 to rotate in the opposite direction, thereby cleaning the pipeline from the reverse direction and improving the cleaning effect.

[0045] As another preferred embodiment, the device adds an axial reciprocating drive mechanism 500. This mechanism is driven to the proximal end (outside the handheld end) of the guide tube 100. Its core function is to drive the guide tube 100 (and all the scrubbing components 200 fixed thereon) to perform intermittent reciprocating motion (i.e., small back-and-forth movements) along its own axis.

[0046] When the scrubbing assembly 200 rotates at high speed and performs radial scrubbing under the drive of the rotary drive mechanism 300, the axial reciprocating drive mechanism 500 works simultaneously, causing the entire scrubbing array to move slowly back and forth within the pipeline. This combined motion produces the effect of "spiral scrubbing" or "grid scrubbing." Simple rotation can only clean a circumference at a fixed position, but with the addition of axial movement, the trajectory of the brush head 260 becomes a spiral line or dense grid covering the entire inner surface of the pipeline, completely eliminating cleaning dead zones.

[0047] Specifically, the axial reciprocating drive mechanism 500 includes a support plate 510, a guide plate 520, an elastic support member 530, a cam 540, and a rotary power member 550.

[0048] Specifically, a support plate 510 is fixedly installed at the end of the guide tube 100 closest to the operator. Behind the support plate 510 (closer to the operator), there is a guide plate 520, which is slidably fitted onto the guide tube 100 to guide and support the axial movement of the guide tube 100. An elastic support member 530, such as a compression spring, is connected between the support plate 510 and the guide plate 520.

[0049] Cam 540 drive mechanism: A rotatable cam 540 is mounted on the guide plate 520. The cam 540 is driven by a small rotary power element 550, which can be a manual knob, a spring mechanism, or a miniature turbine driven by flushing fluid (similar in principle to claim 5, but independent). The cam 540 is profiled to have one or more protrusions.

[0050] In operation, the rotating power component 550 drives the cam 540 to rotate at a constant speed. When the protrusion of the cam 540 rotates to the position of contact with the support plate 510, it begins to push against the support plate 510. The support plate 510 overcomes the elastic force of the elastic support component 530 (compression spring) and pushes the guide tube 100 fixed thereto forward (towards the depth of the pipe) a short distance. As the cam 540 continues to rotate and the protrusion moves away, the pushing force acting on the support plate 510 disappears. At this time, the compressed elastic support component 530 releases its elastic force, pulling the support plate 510 and the guide tube 100 back to their original positions. As the cam 540 continues to rotate, the above-mentioned "pushing-rebounding" process occurs periodically, thereby realizing the precise, rhythmic, intermittent axial reciprocating motion of the guide tube 100. The reciprocating stroke and frequency can be designed by the profile and rotational speed of the cam 540.

[0051] This implementation provides a simple, reliable, and easily controllable purely mechanical reciprocating drive solution. It converts continuous rotary motion into precise linear reciprocating motion without the need for a complex electronic control system. Its motion parameters (such as stroke and frequency) are stable, allowing it to perfectly coordinate with the rotary brushing action and synergistically improve cleaning efficiency.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
