Description

Technical Field

[0001] The present invention belongs to the field of medical devices, and in particular relates to an imaging element cleaning device and an imaging system thereof. Background Art

[0002] In modern medicine, endoscopes are a crucial diagnostic and therapeutic tool, widely used in various surgical procedures, particularly in minimally invasive surgeries such as endoscopic, laparoscopic, and thoracoscopic surgeries. These procedures often require visualization of the target site through an endoscope, allowing the surgeon to perform the procedure without direct contact. However, as the procedure progresses, the exposed surfaces of the endoscope's imaging elements (such as the lens) may become contaminated by moisture, blood, or other bodily fluids, affecting imaging quality and even threatening surgical safety.

[0003] Currently, there are two common methods for cleaning the exposed surfaces of endoscope imaging elements. The first method is to remove the endoscope from the patient, clean its imaging element, and reinsert it into the body. This method is effective, but the process is cumbersome and time-consuming, which not only leads to interruptions in the surgery and reduces surgical efficiency, but also may cause risks such as infection to the patient. The second method is to use other organs or tissues in the body to wipe the exposed surface of the imaging element. Although this method can reduce the operation time, it cannot be thoroughly cleaned or may cause further contamination, resulting in poor cleaning effect and ineffective restoration of imaging quality.

[0004] In view of the above problems, an imaging element cleaning device and an imaging system thereof are proposed. Summary of the Invention

[0005] The object of the present invention is to provide an imaging element cleaning device and an imaging system thereof, thereby improving the cleaning effect of an endoscope.

[0006] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] An imaging element cleaning device, comprising:

[0008] an endoscope sheath, wherein the endoscope sheath is provided with a hollow channel and a transmission shaft channel, wherein the hollow channel is used to accommodate an endoscope insertion portion;

[0009] a transmission shaft, telescopically disposed in the transmission shaft channel, wherein the distal end of the transmission shaft is connected to an elastic bending section, and the distal end of the elastic bending section is connected to the cleaning member;

[0010] The cleaning component is arranged at the distal end of the endoscope sheath. The cleaning component is made of a compressible elastic material and is received in the transmission shaft channel in a non-working state.

[0011] On the other hand, an imaging element cleaning system is provided, comprising the above-mentioned imaging element cleaning device and an endoscope insertion portion detachably connected to the hollow channel.

[0012] Beneficial effects:

[0013] The disclosed embodiment utilizes a rotatable cleaning member that can directly clean the imaging element of an endoscope during surgery, thereby avoiding the tedious step of removing the endoscope from the patient's body.

[0014] The cleaning member of the disclosed embodiment is made of a compressible elastic material and is combined with a retractable transmission shaft to avoid damage to the imaging element or other precision components when not cleaned and to simplify the structure to facilitate direct puncture.

[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0038] The imaging element cleaning device provided in the present application can be used in medical devices, for example, in an endoscope system, and can clean the imaging element or other working elements through a rotatable cleaning component to ensure imaging quality.

[0039] like Figure 1As described, in some embodiments, the cleaning device includes an endoscope sheath 4 and a cleaning member 6, the endoscope sheath 4 is provided with a hollow channel 4.2, and the hollow channel 4.2 is suitable for arranging an endoscope insertion portion and a radio frequency and other elongated members therein; the cleaning member 6 is arranged at the distal end of the endoscope sheath 4, and when the cleaning member 6 rotates, at least partially contacts the distal end surface of the endoscope sheath 4.

[0040] A transmission shaft channel 4.1 is provided on the side of the endoscope sheath 4, and a retractable transmission shaft 7 is provided in the transmission shaft channel 4.1. The cleaning component 6 is located in the transmission shaft channel 4.1 under non-working conditions. This ensures that the cleaning component 6 is not disturbed when the endoscope sheath 4 enters the tissue, and at the same time, the cleaning component 6 does not affect operation and imaging when not in use.

[0041] like Figure 3 As shown, the cleaning member 6 is driven to rotate by the transmission shaft 7. The cleaning member 6 is made of an elastic, compressible, and soft material, and the distal end of the transmission shaft 7 is provided with an elastic bending section 7.2. Based on the above structure, in some embodiments, the operation steps of the device are as follows: insert the endoscope sheath 4 of the cleaning device into the tissue and position its distal end within the working space, insert the endoscope insertion portion and the radio frequency and other long components into the hollow channel 4.2, and apply a rotational torque to the transmission shaft 7 when cleaning is required to drive the cleaning member 6 to rotate. During the rotation, the cleaning member 6 contacts the end face of the working portion to complete the cleaning. With this design, cleaning the endoscope lens or other working components by the rotatable cleaning member can effectively remove dirt, blood stains and other debris, ensure that the imaging quality is not affected, and improve the accuracy and reliability of medical operations.

[0042] It can be understood that the end surface of the working portion can be a radio frequency electrode sheet and is not limited to the lens of the image acquisition unit.

[0043] It is understandable that the endoscope sheath 4 can cooperate with the puncture needle to puncture and establish a channel, and can also enter the tissue through an existing established channel.

[0044] Furthermore, when the elastic bending section 7.2 is not subjected to external force, the angle range with respect to the transmission shaft 7 is 30° to 150°, and the size of the angle is determined by the distal end face angle of the endoscope sheath 4 and the setting position of the endoscope sheath 4.

[0045] In some disclosures, the distal end of the transmission shaft 7 is an elastic bending section 7.2, which is a spring hollow tube. The spring hollow tube 7.2 is connected to the main part of the transmission shaft 7 by welding or integral cutting; the main part of the transmission shaft 7 is a metal transmission soft shaft 7, which can be a flexible metal hose, a metal wire, or a metal braided soft shaft; the proximal end of the transmission shaft 7 inputs a rotational torque through which the distal end is driven to rotate.

[0046] The combination of the elastic bending section, soft cleaning member, and metal transmission flexible shaft in this design enhances the adaptability and stability of the cleaning device in complex medical operating environments, ensuring that the device is not easily damaged during use and has a significant cleaning effect. The cleaning member 6 can be made of a compressible soft material such as sponge, rubber, or silicone. In terms of installation functionality, the cleaning member 6 has good elasticity and compressibility, and can effectively contact the distal end face of the endoscope sheath 4 during rotation, ensuring that the imaging element or other working component surfaces are thoroughly cleaned. In addition, the soft material can effectively avoid damage to the imaging element or other precision components, extending the service life of the equipment.

[0047] At the same time, the compressible soft material can ensure that the cleaning member 6 can be stored in the transmission shaft channel 4.1 when not in use, so as to ensure that the operating space and operating field of view are not affected, and no interference is caused when puncturing with the puncture needle.

[0048] It can be understood that the rotational torque can be controlled manually or electrically, directly or indirectly, and the above function can be achieved as long as the transmission shaft 7 is applied with a torque that meets the requirements. Technicians in this field can eliminate some unreasonable technical solutions based on experience and existing structures.

[0049] like Figure 1 As shown, in some embodiments, the cleaning device includes a handle 1, the proximal end of the endoscope sheath 4 is arranged on the handle 1, and the handle 1 is provided with an adjustment module mounting groove, which is connected to the proximal end of the endoscope sheath 4. A moving component 3 and a rotating component 5 are movably installed in the adjustment module mounting groove. Through such a design, when in use, the moving component 3 drives the reciprocating motion of the transmission shaft 7, and the rotating component 5 is used to drive the rotational motion of the transmission shaft 7.

[0050] like Figure 2 As shown, in some embodiments, a threaded sleeve positioning groove 1.1 is provided in the adjustment module mounting groove, and a rear block positioning groove 1.5 is provided on the proximal surface of the adjustment module mounting groove; a transmission guide groove 1.5 for installing the transmission shaft 7 is provided in the handle 1, and the transmission guide groove 1.5 includes an open groove design set at the distal end of the adjustment module mounting groove, and the transmission shaft 7 passes through the transmission shaft channel 4.1 and is engaged with the transmission guide groove 1.5 and the adjustment component.

[0051] The handle 1 is provided with an endoscope retaining groove 1.2 for positioning the endoscope when inserted. It can be understood that the handle of the inserted endoscope is provided with a structure that cooperates with the endoscope retaining groove 1.2 for positioning.

[0052] like Figure 4 、 Figure 5As shown, a threaded sleeve 8 is installed in the adjustment module mounting groove. The threaded sleeve 8 is annular as a whole. A threaded sleeve positioning block 8.1 is provided on the outer side of the threaded sleeve 8. The threaded sleeve positioning block 8.1 is movably set in the threaded sleeve positioning groove 1.1, thereby completing the installation and positioning of the threaded sleeve 8.

[0053] It is understandable that the threaded sleeve 8 can also be limited by other existing positioning structures.

[0054] like Figure 6 、 Figure 7 As shown, in some embodiments, the moving component 3 is a transmission shaft 3.1, and the overall shape of the transmission shaft 3.1 is semi-cylindrical. The distal end of the transmission shaft 3.1 is provided with a transmission thread 3.1.1, the proximal end is provided with a transmission handle, and the transmission shaft 3.1 is provided with an open rotation channel a3.1.3;

[0055] like Figure 10 Shown, the end surface of the adjustment module mounting groove is provided with a rear stopper 9 and an upper stopper 10 for sealing;

[0056] like Figure 8 、 Figure 9 As shown, the rear block 9 is semi-annular in shape and has a movable shaft channel 9.3 in the center. An eccentric rotating channel b9.4 is provided on the side of the movable shaft channel 9.3 and is connected thereto. A plurality of rear block positioning posts 9.1 are provided on the outer side of the rear block 9. The rear block positioning posts 9.1 are movably mounted in the rear block positioning groove 1.5. A rear block positioning groove 9.2 is provided on the side plane of the rear block 9.

[0057] This eccentrically positioned channel ensures that the height difference between the transmission guide groove 1.4 and the center of the rotating assembly 5 is not excessive, thereby ensuring smoother and more precise movement of the rotating assembly 5. Furthermore, this design allows the mounting slot of the rotating assembly 5 to be open, facilitating installation and maintenance. This open design not only simplifies the assembly process but also improves the maintainability of the assembly, making replacement or adjustment of the rotating assembly 5 more convenient and quick. The sealing design of the rear block 9 and the upper block 10 effectively prevents dust and other impurities from entering the adjustment module, extending the service life of the device.

[0058] like Figure 11As shown, the upper block 10 is generally semi-annular, with multiple upper block retaining posts 10.2 disposed on its outer side. Upper block positioning posts 10.1 are disposed on the side plane of the upper block 10. During installation, the upper block positioning posts 10.1 are movably mounted within the rear block positioning grooves 9.2. Upper block retaining posts 10.2 are movably mounted within the rear block positioning grooves 1.5. This design not only improves installation and removal efficiency but also significantly reduces costs through a rational structure and manufacturing process. It also enhances sealing and the long-term stability of the device, bringing greater efficiency, reliability, and cost-effectiveness to the use of medical devices.

[0059] In some embodiments, the adjustment module installation slot adopts a split design, and the adjustment module installation slot includes a handle cover 2, and a handle guide rail 1.3 for installing the handle cover 2 is provided at the lower part of the adjustment module installation slot. Figure 12 As shown, the handle cover 2 is provided with a handle cover guide rail 2.1 that cooperates with the handle guide rail 1.3. This allows the handle cover 2 to be quickly removed during assembly for easy maintenance and replacement. The coordinated design of the handle guide rail 1.3 and the handle cover guide rail 2.1 not only ensures a secure installation of the handle cover 2, but also effectively distributes the force, ensuring the strength and durability of the overall structure.

[0060] The handle cover 2 is provided with a threaded sleeve handle cover positioning groove 2.2 which has the same function as the transmission guide groove 1.4 and cooperates with the threaded sleeve positioning block 8.1; the handle cover 2 is provided with a handle cover positioning groove 2.3 which has the same function as the rear block positioning groove 1.5 and is used to install the upper block 10.

[0061] With such a design, during installation, the transmission shaft 7 is first inserted into the transmission shaft channel 4.1, and then the threaded sleeve is movably installed on the handle. Then, the rear block 9, the transmission shaft 3.1, the upper block 10, and the handle cover 2 are installed in sequence. After the rotating assembly 5 is inserted into the rotating channel, the far end is connected to the rear end of the transmission shaft 7.

[0062] Further, in some embodiments, as Figures 13-18 As shown, the rotating assembly 5 is a rotating shaft 5.1, which is movably installed in the rotating channel a3.1.3 and the rotating channel b9.4. The transmission thread 3.1.1 is provided with a through hole for the rotating shaft 5.1 to pass through;

[0063] The distal end of the rotating shaft 5.1 is provided with a transmission shaft positioning groove 5.3, and the middle part is provided with at least one rotation limiting ring 5.2. The rotation limiting ring 5.2 is semi-circular, and a limiting ring groove 5.2.1 is provided on the side plane of the rotation limiting ring 5.2.

[0064] The rotating channel a3.1.3 is provided with a rotation limiting groove 3.1.2;

[0065] When installing in this design, first displace the rotation limit ring 5.2 with the rotation limit groove 3.1.2, insert the rotation shaft 5.1 into the installation position, rotate the rotation shaft 5.1 so that the rotation limit ring 5.2 is snapped into the rotation limit groove 3.1.2, and then complete the installation of the limit snap ring 5.4;

[0066] The limit snap ring 5.4 is semicircular in shape as a whole, and a limit snap ring positioning column 5.4.1 is provided on the side plane. When installing, the limit ring groove 5.2.1 and the limit snap ring positioning column 5.4.1 cooperate with each other to complete the fixation.

[0067] like Figure 19-20 As shown, the transmission handle is in a semicircular shape, and a transmission handle positioning groove 3.1.4 is provided on the side plane of the transmission handle. A transmission handle block 3.2 is installed on the transmission handle, and a transmission handle positioning column 3.2.1 that cooperates with the transmission handle positioning groove 3.1.4 is provided on the transmission handle block 3.2 to complete the installation and fixation. Such a design can facilitate installation.

[0068] An imaging element cleaning system includes an imaging element cleaning device and an endoscope insertion portion. The cleaning device includes an endoscope sheath, which is provided with a hollow channel and a drive shaft channel, and the hollow channel is used to accommodate the endoscope insertion portion. The drive shaft is telescopically arranged in the drive shaft channel, with an elastic bending section connected to the distal end, and a cleaning member made of sponge or silicone installed at the end. The cleaning member is stored in the drive shaft channel in a non-working state, and the imaging element is cleaned by the rotation and telescopic movement of the drive shaft during operation. The endoscope insertion portion is detachably connected to the hollow channel, which is convenient for installation and replacement. During use, the endoscope insertion portion is installed in the hollow channel, and the rotation and telescopic movement of the cleaning member are controlled by a handle to achieve rapid and efficient cleaning of the imaging element, ensure imaging quality, and avoid interruption of the operation. The system has a simple structure and is easy to operate, and is suitable for a variety of endoscopic surgery scenarios.
