Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an automatic cleaning device for endoscopic lenses, which can clean the lens at any time during surgery. Background Technology

[0002] Laparoscopic surgery is a newly developed minimally invasive technique that makes it possible to perform surgery through smaller incisions. This results in less tissue damage than traditional surgery. Through a keyhole-sized incision, surgeons can insert tiny light sources, cameras, and surgical instruments. The surgeon guides the manipulation of the surgical instruments based on images transmitted to a monitor. A laparoscopy system includes a tube, an image transmission channel within the tube, a lens at the front end of the image transmission channel (tilted), a fiber optic channel for the light source inside the tube, and a handle at the rear end of the tube. During laparoscopic surgery, the tube is inserted into the abdominal cavity for imaging. However, blood or grease in the abdominal cavity can contaminate the lens area, leading to an unclear surgical field. Furthermore, because the lens and surgical instruments are inside the body, it is difficult to quickly clean the lens and restore the surgical field. The conventional method to address this issue is to remove the tube and clean it externally, which interrupts the surgery, increases surgical time, and prevents the surgeon from timely monitoring of the patient's abdominal cavity, posing significant safety risks. In recent years, other specialized trocars have also emerged, which are equipped with a water-washing channel. When in use, the endoscope tube is retracted into the trocar channel to provide a continuous flow of water for cleaning the lens. They are relatively convenient to use, but the back-and-forth movement of the endoscope tube may cause the surgical field to be lost, and the surgical point needs to be re-found after the endoscope tube is reinserted. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing an automatic cleaning device for endoscope lenses, which meets the requirements for cleaning endoscope lenses in the channel.

[0004] The technical solution of this utility model is: an automatic cleaning device for endoscope lenses, including a main unit and a disposable flushing tube.

[0005] The flushing tube has a scope insertion channel and an internal flushing channel. The inner wall of the scope insertion channel has a flushing hole for spraying flushing liquid onto the endoscope lens in the channel. The front end of the flushing tube has an opening for exposing the end of the scope in the channel. The flushing hole is connected to the front end of the internal flushing channel. The rear end of the internal flushing channel is connected to a liquid inlet tube and an air tube.

[0006] The main unit is equipped with an air pump, a peristaltic pump, and a heating platform. The heating platform is used to place the liquid supply bottle and heat the flushing liquid loaded in the bottle. The liquid supply bottle, peristaltic pump, and inlet pipe are connected in sequence to inject the cleaning liquid into the internal flushing channel. The air pump, filter, collection bottle, and air pipe are connected in sequence to aspirate the accumulated fluid in the human body cavity and discharge it into the collection bottle.

[0007] By adopting the above technical solution, airflow and water flow are provided by the air pump and peristaltic pump on the main unit, respectively, and connected to the internal flushing channel of the flushing tube through pipeline. The flushing hole is used to spray out flushing liquid or draw in body fluid, thereby meeting the requirement of cleaning the endoscope lens in the channel without removing the endoscope for cleaning. In addition, the lens is also exposed at the front end of the flushing tube, which provides a better field of vision for the surrounding area. Furthermore, the addition of flushing liquid through the heating platform can prevent the lens from fogging up during flushing, thus avoiding affecting the field of vision.

[0008] A further feature of this invention is that the opening is formed by cutting into the upper end of the flushing pipe and extending towards the front end, and the front end of the flushing pipe has a retaining plate below the opening. The flushing hole is set on the retaining plate and faces the lens that is tilted from top to bottom and backward.

[0009] With the above-mentioned further configuration, the lens corresponds to the opening and the retaining plate at the front end of the rinsing tube. The opening allows the upper end of the lens to be exposed, and the retaining plate below is used to set the rinsing hole to spray water onto the lens.

[0010] A further feature of this invention is that the opening is also cut downwards at an angle from the upper end of the flushing pipe toward the front end.

[0011] By adopting the above-mentioned further settings, the downward angled cut makes the downward opening larger, allowing more of the lens to be exposed and providing a better field of view.

[0012] A further feature of this invention is that the flushing hole is a vertical hole, and the flushing liquid is sprayed upward from the flushing hole perpendicular to the axial direction of the flushing pipe.

[0013] With the above-mentioned further configuration, the flushing hole can convert the flushing liquid into a jet that is perpendicular to the axis of the flushing pipe, impacting the lens area.

[0014] A further feature of this invention is that the rinsing tube has an annular structure that surrounds the endoscope tube insertion channel, and the tube wall of the rinsing tube is hollow to form the internal rinsing channel; a sealing ring is provided at the front end of the endoscope tube insertion channel to contact the outer periphery of the endoscope tube.

[0015] With the above-mentioned further design, the formation structure of the endoscope tube insertion channel and the internal rinsing channel is simple, formed by the tubular structure of the rinsing tube itself; and the sealing ring can provide damping during endoscope tube adjustment, improve the adjustment feel, and prevent blood or other liquids from seeping between the rinsing tube and the endoscope tube.

[0016] A further feature of this invention is that the flushing tube has a circular tube section at the rear that is compatible with the puncture device, and a C-shaped tube section at the front that is open at the top. The internal flushing channel is located in the lower end wall of the flushing tube.

[0017] With the above-mentioned further design, the round tube segment can be compatible with ordinary trocars, eliminating the need for a special trocar; and the C-shaped tube segment is also easy to deform and facilitates the insertion of the endoscope tube.

[0018] A further feature of this invention is that an adjustment assembly is provided on the disposable rinsing tube. The endoscope tube is driven by the adjustment assembly to move back and forth within the endoscope tube insertion channel, thereby adjusting the axial relative position of the lens and the rinsing tube. The adjustment assembly includes an adjustment gear and a transmission rack that mesh with each other. The adjustment gear is rotatably mounted on the rear end of the rinsing tube, and the transmission rack is arranged along the axial direction of the rinsing tube. The transmission rack is mounted on the endoscope and, through its cooperation with the adjustment gear, drives the endoscope to move.

[0019] By adopting the above-mentioned further settings, the advance distance of the lens tube can be accurately determined each time through the cooperation of the transmission rack and the adjusting gear, so as to ensure that the lens can be adjusted to the appropriate position, so that the lens is aligned with the appropriate position of the front opening of the rinsing tube, and the exposed lens provides a better field of view of the surroundings; and it also makes it easier for the lens to tilt towards the appropriate position of the rinsing hole, so that the rinsing hole can provide a good rinsing effect on the lens.

[0020] A further feature of this invention is that the adjustment assembly also includes an adjuster and a controller. The adjusting gear is rotatably mounted on the adjuster. The adjuster is located at the rear end of the flushing tube and has a pipe interface communicating with the internal flushing channel. The pipe interface is used to connect the liquid inlet pipe and the air pipe. The transmission rack is mounted on the controller. The controller is detachably mounted at the rear end of the endoscope. The controller also has a control switch, which is electrically connected to the main unit.

[0021] With the above-mentioned further configuration, the regulator is used to install the adjusting gear and the inlet pipe, and the controller is used to install the transmission rack and the control switch. The regulator and the controller are connected by the gear and the rack. When the regulator is installed on the endoscope, it can drive the endoscope tube to move.

[0022] Further features of this invention: The adjuster has a gear cavity and a rack cavity. The rack cavity communicates with the gear cavity via a through-hole. The rear end of the rack cavity has an insertion port for inserting a transmission rack. The transmission rack is guided to slide back and forth by guide rails and grooves on both sides of the rack cavity. The gear cavity is open at both axial ends. The adjusting gear is inserted into the gear cavity. An adjusting knob and a baffle are respectively provided at both ends of the adjusting gear. The adjusting knob and the baffle can restrict the adjusting gear from disengaging from the gear cavity. The back of the adjusting knob has an arc-shaped groove. The adjuster has a limiting block on one side of the back of the corresponding adjusting knob. The limiting block is set in the arc-shaped groove and slides relative to the arc-shaped groove. The controller also has a tube clamp and a U-shaped clip. The tube clamp includes a first clamp and a second clamp. A clamping hole for the endoscope tube to pass through is formed between the first clamp and the second clamp. The two clamps are driven by a locking member to clamp or release the endoscope tube. The U-shaped clip can be locked onto a positioning post provided on the endoscope handle.

[0023] With the above-mentioned further configuration, a gear and a rack are respectively installed in the gear cavity and rack cavity. The transmission rack is guided back and forth by the guide rail and guide groove. The rotation angle of the adjustment gear is limited by the cooperation of the limit block and the arc groove. The controller is clamped on the endoscope. The locking device drives the two clamping plates to move closer or further away, thereby changing the size of the clamping hole to clamp or loosen the endoscope tube. It is also secured to the positioning post on the endoscope handle by a U-shaped clip, thereby ensuring the direction of the endoscope insertion into the flushing tube, so that the lens is tilted towards the flushing hole.

[0024] Further features of this invention include: a temperature control switch, an air pump speed control switch, and a peristaltic pump speed control switch on the main unit. The power of the air pump and the peristaltic pump are respectively adjusted and controlled by the corresponding speed control switches. The temperature control switch can control the heating temperature of the heating platform to be at or above a certain temperature. The heating platform has a heating cavity composed of a chassis and an outer cylindrical wall. An outlet is also provided in the center of the chassis. The rinsing pipe has a heating and temperature control function to heat the rinsing liquid in the internal rinsing channel.

[0025] With the above-mentioned further configuration, the flow rates of the rinsing water and the suction air can be adjusted separately by the speed control switch to avoid excessive pressure. The heating platform can heat the bottom and periphery of the supply bottle through the chassis and cylinder wall. In addition, the endoscope tube has a heating and constant temperature function to keep the rinsing liquid pumped out by the peristaltic pump continuously warm. Attached Figure Description

The flushing hole 311 is connected to the front end of the internal flushing channel 32. The rear end of the internal flushing channel 32 is connected to the inlet tube 321 and the air tube 322.

[0041] An adjustment assembly 4 is provided on the disposable flushing tube 3. The endoscope tube 21 is driven by the adjustment assembly 4 to move back and forth within the endoscope tube insertion channel 31, thereby adjusting the axial relative position of the lens 22 and the flushing tube 3. The adjustment assembly 4 includes an adjustment gear 41 and a transmission rack 42 that mesh with each other. The adjustment gear 41 is rotatably mounted on the rear end of the flushing tube 3. The transmission rack 42 is arranged axially along the flushing tube 3. The transmission rack 42 is mounted on the endoscope 2 and, through its cooperation with the adjustment gear 41, drives the endoscope 2 to move. The adjustment assembly 4 also includes an adjuster 5 and a controller 6. The adjustment gear 41 is rotatably mounted on the adjuster 5. The adjuster 5 is located at the rear end of the flushing tube 3 and has a pipe interface 51 that communicates with the internal flushing channel. The pipe interface 51 is used to connect the inlet pipe 321 and the air pipe 322. The transmission rack 42 is mounted on the controller 6. The controller 6 is detachably mounted on the rear end of the endoscope 2. The controller 6 also has a control switch 61, which is connected to the main unit 1 via a cable. The regulator 5 has a gear cavity 52 and a rack cavity 53. The rack cavity 53 is connected to the gear cavity 52 via a through-hole 54, which facilitates the meshing of the gear and the rack. The rear end of the rack cavity 53 has an insertion port for inserting the transmission rack 42. The transmission rack 42 is guided to slide back and forth by the guide rails and guide grooves on both sides of the rack cavity 53.

The U-shaped clip 63 is located at the rear end of the controller 6 and is locked onto the positioning post 231 provided on the endoscope handle 23.

[0042] The main unit 1 is equipped with an air pump, a peristaltic pump 12, and a heating platform 13. The air pump is located inside the main unit and is not shown in the figure. The heating platform 13 is used to place the supply bottle (not shown in the figure) and can heat the rinsing liquid loaded in the bottle. The supply bottle, peristaltic pump 12, and inlet pipe 321 are connected in sequence through pipelines to inject cleaning liquid into the internal rinsing channel 32. The air pump, filter 14, collection bottle 15, and air pipe 322 are connected in sequence to aspirate the accumulated fluid in the body cavity and discharge it into the collection bottle 15. The filter is a disposable component and is connected to the main unit via a Luer connector for easy and quick replacement. The air pump can be configured to pump or discharge air. When configured to pump air, the collection bottle can be used to collect residual liquid during rinsing. When configured to discharge air, the collection bottle is not needed. The main unit 1 is also equipped with a temperature control switch, an air pump speed control switch 16, and a peristaltic pump speed control switch 17. The power of the air pump and peristaltic pump 12 is adjusted and controlled by their respective speed control switches. The temperature control switch can control the heating temperature of the heating platform 13 to 37°C or higher, preferably 37°C, which is suitable for human body temperature. The heating platform 13 has a heating chamber 133 composed of a base 131 and an outer cylindrical wall 132. An outlet 1311 is also provided in the center of the base 131. The liquid supply bottle can be placed upside down in the heating chamber 133, and the bottle head can extend from the outlet 1311. The rinsing pipe has a heating and temperature control function to heat the rinsing liquid in the internal rinsing channel, such as through heating wires or heating plates.

[0043] The internal flushing channel of the flushing tube can be a single channel connected to both an air pump (for suction or exhaust) and a peristaltic pump for flushing the lens of the endoscope or aspirating bodily fluids; or it can be two channels connected to an air pump and a peristaltic pump respectively, or more than two channels. Multiple internal flushing channels can be interconnected. One or more flushing holes can be provided for spraying flushing fluid or aspirating bodily fluids. The flushing fluid can be sterile saline or clean water. The internal flushing channel can also serve as an air supply channel, providing a high-pressure airflow to quickly dry residual water stains near the lens; or as an air suction channel to quickly aspirate residual water stains near the lens. The control switch is a three-position bridge switch. When the switch is horizontal, the flushing, air spraying, or air suction functions are off; pressing one side of the switch activates the flushing function; similarly, pressing the other side activates the air spraying or air suction function.

[0044] The flushing tube of this device has a simple structure and low cost. It can be manufactured through conventional processing methods such as 3D printing, injection molding, and extrusion. It is compatible with ordinary puncture instruments and can be customized according to the length of the endoscope.

[0045] During assembly, the endoscope tube 21 is inserted into the tube insertion channel 31 of the flushing tube 3 of this device, and then the controller 6 in the adjustment assembly 4 set on the rear end of the flushing tube 3 is installed on the endoscope. Specifically, the tube clamp 62 is clamped on the rear end of the endoscope tube 21 and the U-shaped clip 63 is clamped on the positioning post 231, thereby ensuring the direction of the endoscope tube 21 inserted into the flushing tube 3, so that the lens 22 is tilted towards the flushing hole.

[0046] Then, they are placed together into a regular trocar. The circular tube section 35 of the irrigation tube and the sealing ring of the trocar are sealed to prevent gas leakage during the operation. The transmission rack 42 on the endoscope and the adjusting gear 41 on the irrigation tube mesh with each other. By rotating the adjusting knob 411, the gear is rotated, thereby adjusting the axial relative position of the lens 22 and the irrigation tube 3 for fine adjustment. This makes it easier for the lens 22 to be aligned with the front opening 33 of the irrigation tube 3. The exposed lens 22 provides a better view of the surrounding area. It also makes it easier for the lens 22 to be tilted towards the irrigation hole 311 at a suitable position. The irrigation hole 311 provides a good rinsing effect for the lens 22, which meets the requirement of cleaning the endoscope lens 22 in the channel without having to remove the endoscope for cleaning.

[0047] When in use, place the liquid supply bottle on the heating platform 13 and keep the temperature of the water slightly higher than the body temperature to prevent the lens 22 from fogging. Connect the external peristaltic pump 12 to the liquid supply bottle and control the water output for rinsing or aspirating body fluids through the control switch 61. Control the flow rate of the rinsing water and the air intake airflow through the speed control knob.

[0048] The flushing tube, filter, collection bottle, and tubing in this invention are for single use only, which can avoid cross-infection among patients and facilitate cleaning and maintenance of the main unit.

[0049] It should be noted that in the description of this utility model, all directional indicators (such as up, down, forward, backward, etc.) are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0050] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. In the description of this utility model, "a number" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0051] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
