Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to a pipeline component and an endoscope. Background Art

[0002] With the advancement of science and technology and the improvement of people's living standards, endoscopic minimally invasive surgery has been widely used and achieved good results. However, there are still some problems in the use process. The temperature of the surgical endoscope is somewhat different from the temperature of the human body. Due to the temperature difference, the endoscope will fog up. In addition, during the operation, liquids such as dirty blood adhere to the surface of the lens, directly or indirectly affecting the imaging quality and interfering with the surgical operation. Therefore, during the operation, the endoscope lens needs to be withdrawn from the human body, soaked in heated saline, and wiped with cotton balls or cotton gauze. The saline used in the process needs to be repeatedly taken off the operating table and heated with a sterile heating vessel before being sent to the operating table again, which increases the manpower burden and slows down the surgical operation. At the same time, the saline heating process and the cotton ball or cotton gauze wiping process may cause contamination and other problems. Summary of the invention

[0003] In view of this, it is necessary to provide an improved pipeline assembly, which comprises a defogger assembly arranged in an outer pipeline. The defogger assembly comprises a lens brush. When the endoscope is in operation, the lens brush can wipe the lens after fogging, thereby removing the water mist on the lens of the pipeline assembly, so that the lens of the pipeline can be cleaned without extending the endoscope outside the body; the manpower burden and the complexity of the surgical operation are reduced; the endoscope using the pipeline assembly has broad application prospects in clinical practice.

[0004] The present invention provides a pipeline assembly for an endoscope, wherein the pipeline assembly comprises an outer pipeline, a defogger assembly, a driving assembly and a lens, wherein the lens is fixedly mounted at the end of the outer pipeline, the defogger assembly is arranged in the outer pipeline, and the driving assembly is arranged at an end of the outer pipeline relatively far away from the lens, the defogger assembly and the driving assembly are interconnected, and the driving assembly drives the defogger assembly to move so that the defogger assembly wipes the outer surface of the lens.

[0005] Such an arrangement enables the demisting assembly to remove the mist from the outer surface of the endoscope lens when the endoscope is working inside the human body, thereby reducing the steps of removing the endoscope from the human body to remove the mist from the lens, reducing the complexity of the operation and reducing the risk of the operation.

[0006] In order to remove the water mist on the lens, the defogger assembly includes a sliding pipe, a sliding member and a lens brush. The sliding pipe is arranged on the inner wall of the outer pipe and is symmetrically arranged about the axis of the outer pipe. The sliding member is slidably installed in the sliding pipe and both ends of the sliding member are connected to the driving assembly. The lens brush is fixedly installed on the sliding member and moves with the sliding member to wipe the outer surface of the lens.

[0007] In this way, by arranging a sliding pipe in the outer pipe, the sliding member and the sliding brush slide in the sliding pipe, and the sliding brush wipes the lens to remove the water mist on the lens.

[0008] In order to enable the sliding member to drive the lens brush, the sliding member is arranged as two guide lines parallel to each other.

[0009] In this way, by arranging the sliding member into two mutually parallel guide lines, it is convenient to arrange the lens brush between the two guide lines.

[0010] In order to enable the lens brush to wipe the lens, the lens brush includes a fixed node, an elastic thread and gauze, both ends of the elastic thread are fixedly installed on the guide wire through the fixed node, and the gauze is slidably installed on the elastic thread.

[0011] With such arrangement, the guide wire drives the gauze to move on the lens to wipe the lens.

[0012] In order to meet the needs of multiple wiping, the number of the lens brushes is set to be multiple, and the multiple lens brushes are arranged at equal intervals along the sliding member.

[0013] In this way, a plurality of lens brushes are arranged according to the layout direction of the guide lines, so that the plurality of lens brushes can wipe the lens multiple times.

[0014] In order to enable the lens brush to completely wipe the lens, a sliding groove is provided at the lens end of the outer tube. The sliding groove is arranged on the outer periphery of the lens and symmetrically arranged about the center line of the lens. The two ends of the sliding groove are respectively connected to the symmetrically arranged sliding tubes.

[0015] With such arrangement, when the guide wire moves on the lens, the guide wire passes through the sliding groove at the lens end, so that the guide wire moves along the sliding grooves on both sides of the lens respectively and the lens brush completely brushes over the lens.

[0016] In order to drive the sliding part to slide and the lens brush to wipe the lens, the driving assembly includes a gap assembly and a fixed bracket, wherein the fixed bracket is fixedly installed on the end of the outer pipe away from the lens, the fixed bracket is hollow and connected to the sliding pipe, and the sliding part passes through the sliding pipe and the hollow fixed bracket in sequence and is arranged on the rotating assembly, so that the rotating assembly drives the sliding part to move.

[0017] In this way, by arranging the driving assembly, the sliding member and the lens brush can be driven to slide on the sliding tube, and the lens brush can actively wipe the lens.

[0018] In order to fix the single sliding distance of the sliding member and the lens brush in the pipe, the rotating assembly includes a knob, a rotating shaft and a ratchet. The rotating shaft passes through the fixed bracket and can rotate relative to the fixed bracket. The ratchet is fixedly installed on the rotating shaft and is located in the fixed bracket. The knob is fixedly installed on the rotating shaft and is located outside the fixed bracket. The two ends of the sliding member are respectively fixedly installed on different sides of the rotating shaft.

[0019] In this way, by setting up an intermittent mechanism, the distance of a single sliding of the lens brush and the sliding member in the pipe is fixed, and the distance of a single sliding is greater than the maximum diameter of the lens end face, so that the lens brush will not block the lens.

[0020] In order to fix the sliding member with the rotating shaft, the driving assembly also includes a clamping member, and the sliding member includes a turn-in end, a turn-out end and a surrounding portion close to the turn-out end. The turn-in end and the turn-out end are both fixed to the rotating shaft by the clamping member, and the surrounding portion surrounds the rotating shaft. When the ratchet is working, the turn-in end reels in the line and the surrounding portion releases the line, so that the sliding member can slide in the sliding pipe.

[0021] Such an arrangement enables the rotating shaft to drive the sliding member to rotate through the clamping member during the rotation process.

[0022] The present invention also provides an endoscope, comprising an operating component, a shell, and a pipeline component as described in any one of the above items, wherein the operating component is arranged inside the shell, and the pipeline component is connected to the operating component and controls the operating component.

[0023] The present invention provides an improved pipeline component. The pipeline component is provided with a defogger component in an outer pipeline. The defogger component includes a lens brush. When the endoscope is in operation, the lens brush can wipe the lens after the lens is fogged, so as to remove the water mist and dirt on the lens of the pipeline component, so that the lens of the pipeline can be cleaned without the endoscope extending out of the body; the manpower burden and the complexity of the operation are reduced; the endoscope using the pipeline component has broad application prospects in clinical practice.

[0035] The pipe component 100 is used in the endoscope 300 to extend into the interior of an object to search for a target. Through the lens 40 at the front end of the pipe and the optical transmission parts inside the pipe, the scene captured by the lens 40 is projected to the eyepiece end at the rear end, and then projected onto the display screen through conversion. Then, the pipe component 100 is controlled by the operating component 200 to search for a target inside the object.

[0036] In this embodiment, the pipeline assembly 100 is used in a medical endoscope 300, which can be inserted into the human body or animal body to observe the internal conditions and obtain the pathological conditions of the observed part, such as a cystoscope, a gastroscope, etc., to examine the conditions of the corresponding positions of the human body or animal body.

[0037] It is understandable that the present invention does not limit the application of the pipeline assembly 100 to only the medical endoscope 300 device. In other embodiments, the pipeline assembly 100 can also be used in industrial flaw detection, safety detection and other detection fields.

[0038] There are still some problems during the use of the endoscope 300. Since there is a certain gap between the temperature of the surgical endoscope 300 and the temperature of the human body's internal environment, the endoscope 300 will fog up. In addition, during the operation, liquids such as dirty blood adhere to the surface of the lens 40, which directly or indirectly affects the imaging quality and interferes with the surgical operation.

[0039] In view of the above technical problems, it is necessary to provide an improved pipeline assembly 100, wherein the pipeline assembly 100 is provided with a defogger assembly 20 in an outer tube, and the defogger assembly 20 includes a lens brush 23. During operation of the endoscope 300, the lens brush 23 can wipe the lens 40 after the lens 40 is fogged, thereby removing the fog on the lens 40 on the pipeline assembly 100, so that the lens 40 of the pipeline can be cleaned without the endoscope 300 extending out of the body, thereby reducing the manpower burden and the complexity of the surgical operation.

[0040] In this embodiment, the pipeline assembly 100 includes an outer pipeline 10, a defogger assembly 20, a drive assembly 30 and a lens 40. The lens 40 is fixedly mounted at one end of the outer pipeline 10, the drive assembly 30 is arranged at the other end of the outer pipeline 10, the defogger assembly 20 is arranged at an end of the outer pipeline relatively far away from the lens 40, the outer pipeline 10 is used to install the defogger assembly 20 and other internal optical transmission components so that the internal devices are isolated from the external space, the lens 40 is used to observe the internal situation, and the defogger assembly 20 is used to remove water mist on the lens 40.

[0041] Specifically, the outer pipe 10 is in the shape of a circular tube. The outer pipe 10 is a pipe made of metal material and is used to enclose optical transmission devices and other functional devices. One end of the outer pipe 10 is fixedly connected to the operating component 200, and the other end is fixedly connected to the lens 40, and the end at which the outer pipe 10 and the lens 40 are interconnected is set as an inclined end.

[0042] It should be noted that the outer pipe 10 is usually made of metal material, which is harmless to the human body, but the present invention is not limited to the use of metal materials to make the outer pipe 10. In other embodiments, the outer pipe 10 can also be set to a hose made of polypropylene, polyvinyl chloride and other materials, as long as the outer pipe 10 can enclose the optical device and the working device.

[0043] In this embodiment, the defogger assembly 20 further includes a sliding pipe 21 , which is disposed on the inner wall of the outer pipe 10 and symmetrically disposed about the axis of the outer pipe 10 , and is used to set a sliding member 22 and a lens brush 23 .

[0044] Specifically, in this embodiment, the sliding pipe 21 is roughly in the shape of a circular tube, the number of the sliding pipes 21 is set to two, and extends from the outer pipe 10, and the sliding pipe 21 is attached to the inner wall of the outer pipe 10, wherein the sliding pipe 21 attached to the outer pipe 10 is symmetrically arranged about the axis of the outer pipe 10.

[0045] It is understandable that the present invention does not limit the configuration shape of the sliding pipe 21 . In other embodiments, the sliding pipe 21 is configured as a square pipe as long as the sliding member 22 can slide in the sliding pipe 21 .

[0046] In this embodiment, the defogger assembly 20 further includes a sliding member 22 , which is slidably installed in the sliding pipe 21 ; the sliding member 22 is used to slide along the sliding pipe 21 and drive the lens brush 23 to move.

[0047] Specifically, in this embodiment, the sliding member 22 is configured as two mutually parallel guide lines 221, which flow into the sliding pipe 21 at the lower end, pass through and wipe the lens 40, and then flow out through the sliding pipe 21 on the upper side. The guide line drives the lens brush 23 to slide in the sliding pipe 21 and wipe the lens 40.

[0048] It should be noted that the present invention does not limit the material of the guide wire 221. In the present embodiment, the guide wire 221 is selected to be a metal wire. In other embodiments, the guide wire 221 can also be set to be a plastic wire or a cotton wire, as long as the guide wire 221 can drive the lens brush 23 to move.

[0049] It is understandable that the present invention does not limit the setting style of the sliding member 22. In other embodiments, the sliding member 22 is set as a guide line 221, and the lens brush 23 is fixedly installed on the guide line 221. The movement of the guide line 221 can drive the lens brush 23 to move.

[0050] In this embodiment, the defog assembly 20 further includes a lens brush 23 . The lens brush 23 is fixedly mounted on the sliding member 22 . The lens brush 23 is used to wipe the lens 40 .

[0051] Specifically, in this embodiment, the lens brush 23 includes a fixed node 231, an elastic thread 232 and a gauze 233. The fixing member is used to fix the elastic thread 232. The elastic thread 232 is used to carry the gauze 233. The gauze 233 is used to wipe the lens 40. The two ends of the elastic thread 232 are respectively fixedly mounted on two parallel guide wires 221 through the fixed node 231. The elastic thread 232 is vertically arranged to the guide wire 221. The gauze 233 is passed through the elastic thread 232. The gauze 233 moves with the movement of the guide wire 221 and wipes the lens 40 through the gauze 233.

[0052] It is understandable that the present invention is not limited to wiping the lens 40 by setting the elastic thread 232 and the gauze 233. In other embodiments, an elastic water-absorbing member may be set between the guide lines 221, as long as the elastic water-absorbing member can wipe and absorb the water mist on the lens 40.

[0053] In this embodiment, the number of lens brushes 23 is set to be multiple, and the lens brushes 23 are arranged at equal intervals along the sliding member 22, and the distance between adjacent lens brushes 23 is greater than the distance from one end of the sliding pipe 21 connected to the lens 40 to the other end of the sliding pipe 21 connected to the lens 40, so that the lens brush 23 will not block the lens 40 during a single movement.

[0054] It should be noted that the present invention is not limited to driving the lens brush 23 to slide by setting a sliding pipe 21 and a sliding member 22, so that the lens brush 23 slides on the lens 40 to wipe the lens 40; in other embodiments, an intermittent brush head structure can be set at the end of the pipe assembly 100, which can swing back and forth along the outer surface of the lens 40. After the pipe assembly 100 enters the human body or animal body and the lens 40 is fogged, the lens 40 is wiped by the intermittent brush head so that the water mist and dirt on the lens 40 are eliminated.

[0055] In this embodiment, a sliding groove 11 is provided at the end of the outer tube 10 close to the lens 40 , and the sliding groove 11 is used to slide and accommodate the guide wire 221 .

[0056] Specifically, in the present embodiment, the lens 40 is disposed in the outer tube 10 and is clamped to the outer tube 10, the sliding tubes 21 are respectively disposed on both sides of the lens 40, the outlets of the two sliding tubes 21 are respectively located at both ends of the lens 40, and the outer periphery of the lens 40 is provided with sliding grooves 11, which are symmetrically arranged about the center line of the lens 40; after the guide wire 221 slides out from the sliding tube 21 at one end, the sliding grooves 11 on both sides of the lens 40 are separated, so that the two parallel guide wires 221 move along the sliding grooves 11 on both sides of the lens 40, and as the distance between the two sides changes from small to large and then from large to small, the elastic thread 232 between the guide wires 221 is stretched or contracted, thereby driving the gauze 233 installed on the elastic thread 232 to move on the mirror surface and wipe the lens 40.

[0057] It can be understood that the present invention is not limited to only setting the form of the sliding groove 11 so that the guide wire 221 slides in the slide rail and then wipes the lens 40. In other embodiments, the guide wire 221 is set as a transparent wire, and the guide wire 221 can pass through the middle of the lens 40, as long as the guide wire 221 can drive the lens brush 23 to wipe the lens 40.

[0058] In this embodiment, the driving mechanism includes a fixing bracket 32 ​​, which is disposed at one end of the outer pipe 10 and is used to fix the rotating assembly 31 .

[0059] Specifically, in this embodiment, the fixed bracket 32 ​​is rectangular, hollow inside, and one side of the fixed bracket 32 ​​relatively close to the pipe is removed. The cross-section of the fixed bracket 32 ​​is U-shaped, so that the interior of the fixed bracket 32 ​​is connected to the sliding pipe 21 inside the outer pipe belt.

[0060] It can be understood that the present invention does not limit the setting form of the fixed bracket 32. In other embodiments, the fixed bracket 32 ​​can also be set as a cylindrical structure, and the side of the cylindrical fixed bracket 32 ​​is connected to the outer pipe 10, as long as the interior of the fixed bracket 32 ​​is connected to the sliding pipe 21 of the outer pipe 10.

[0061] In this embodiment, the defogger assembly 20 further includes a rotating assembly 31 , which is rotatably mounted inside a fixed bracket 32 ​​and is used to drive the sliding member 22 and the lens brush 23 to slide intermittently.

[0062] Specifically, in the present embodiment, the rotating assembly 31 is rotatably mounted inside the fixed bracket 32 ​​, and the sliding member 22 is connected to the rotating assembly 31 , and the sliding member 22 is driven to intermittently move by the rotating assembly 31 .

[0063] It can be understood that the present invention is not limited to only driving the sliding member 22 to slide intermittently in the sliding tube 21 and driving the lens brush 23 to slide on the outside of the lens 40 to wipe the lens 40 by the rotating component 31. In other embodiments, the rotation of the motor can also be electrically controlled to drive the sliding member 22 to slide intermittently in the sliding tube 21 and drive the lens brush 23 to wipe the lens 40.

[0064] In this embodiment, the rotating assembly 31 includes a knob 311, a rotating shaft 312 and a ratchet 313. The ratchet 313 is used to make the rotating shaft 312 rotate in one direction without reverse rotation. The rotating shaft 312 is used to drive the ratchet 313 to rotate, and the knob 311 is used to drive the rotating shaft 312 to rotate.

[0065] Specifically, in the present embodiment, the rotating shaft 312 is inserted into the fixed bracket 32 ​​and can rotate relative to the fixed bracket 32. The ratchet 313 is installed inside the fixed bracket 32 ​​and is fixedly connected to the rotating shaft 312 by a key connection. The rotating shaft 312 can drive the rotation of the ratchet 313, and a clamping piece that cooperates with the ratchet 313 is provided inside the fixed bracket 32, so that the ratchet 313 can only rotate in one direction. The knob 311 is fixedly installed at the end of the rotating shaft 312 extending out of the fixed bracket 32. The user drives the rotating shaft 312 to rotate by rotating the knob 311.

[0066] It can be understood that the present invention is not limited to the method of setting the ratchet 313 so that the rotating shaft 312 can only rotate in one direction. In other embodiments, a unidirectional rotating drive motor can be set to drive the rotating shaft 312 to rotate, thereby driving the sliding member 22 to move in the sliding channel, and then driving the lens brush 23 to wipe the lens 40.

[0067] In this embodiment, the rotating assembly 31 further includes a clamping member 314 . The clamping member 314 is fixedly mounted on the rotating shaft 312 and is used to fix the sliding member 22 on the rotating shaft 312 .

[0068] Specifically, the clamping member 314 is a screw, and the clamping member 314 is fixedly installed on the rotating shaft 312 by means of rotational installation. The turning-in end of the guide wire 221 is fixedly installed on the rotating shaft 312 by the clamping member 314, and the turning-out end of the guide wire 221 passes through the sliding pipe 21 and the lens 40 and is fixedly installed on the rotating shaft 312 by the clamping member 314, and the winding portion is wound on the rotating shaft 312, wherein the turning-in end and the turning-out end of the guide wire 221 are respectively on different sides of the rotating shaft 312, and by driving the rotating shaft 312 to rotate, the turning-in end of the guide wire 221 is wound around the rotating shaft 312 as the rotating shaft 312 rotates, so that the winding portion of the guide wire 221 is released from the rotating shaft 312, thereby making the guide wire 221 always in a taut state in the sliding pipe 21, and making the guide wire 221 move intermittently with the rotation of the rotating shaft 312.

[0069] It should be noted that before the rotating assembly 31 works, a portion of the rotating end of the guide wire 221 needs to be wrapped around the rotating shaft 312. This arrangement ensures that the guide wire 221 always moves in the sliding pipe 21 during the rotation process.

[0070] The present invention also provides an endoscope 300, which includes an operating component 200, a shell and a pipeline component 100 as described in any one of the above items, wherein the operating component 200 is arranged inside the shell, the pipeline component 100 and the operating component 200 are interconnected, and the operating component 200 is used to control the pipeline component 100.

[0071] The working principle of the pipeline assembly 100 and the endoscope 300 is briefly described below:

[0072] The pipe assembly 100 is inserted into the body of an animal or a human body, and the movement of the pipe assembly 100 in the body is controlled by the operating assembly 200, and the scene transmitted back by the lens 40 of the pipe assembly 100 on the screen is observed;

[0073] After working for a period of time, due to the temperature difference between the pipe assembly 100 and the body temperature, water mist will be generated in front of the lens 40, blocking the lens 40 from observing the body's situation; by turning the knob 311, the rotating shaft 312 and the ratchet 313 are driven to rotate, one side of the rotating shaft 312 retracts the guide wire 221, and the other side of the rotating shaft 312 turns out the guide wire 221, so that the guide wire 221 slides in the sliding pipe 21, and the guide wire 221 drives the lens brush 23 to move, and the lens brush 23 passes through the end of the lens 40 of the outer pipe 10, slides along the sliding groove 11 at the end through the guide wire 221, drives the elastic thread 232 and the gauze 233 to slide along the outer side of the lens 40, and wipes the lens 40;

[0074] After the water mist is generated, the knob 311 can be turned to make different lens brushes 23 wipe the lens 40. After the endoscope 300 is used, the lens brush 23 on the pipe assembly 100 can be removed and the external pipe 10 can be sterilized at high temperature and high pressure. Before the next use, a set of clean lens brush 23 components can be installed.

[0075] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0076] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, appropriate changes and modifications to the above embodiments are within the scope of protection claimed by the present invention.
