Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a cleaning device and system for minimally invasive surgical instruments. Background Technology

[0002] In minimally invasive surgery, components such as radiofrequency electrodes, grinding heads, and planers are exposed inside the patient's body. As the surgery progresses, contaminants such as blood, bodily fluids, and tissue debris accumulate on the surfaces and within the channels of these components. These contaminants can affect the performance and precision of the components, and may even threaten the safety of the surgery.

[0003] Currently, common cleaning methods include removing the surgical instrument from the body during surgery and cleaning it manually, or wiping the surface of the instrument with other organs or tissues. While the former is effective, it is cumbersome and interrupts the surgery, increasing the risk to the patient; while the latter saves time, it often fails to clean thoroughly and carries the risk of further contamination.

[0004] Therefore, existing cleaning methods cannot achieve real-time and thorough cleaning during surgery, especially for various working parts inside the endoscope channel, where contaminants on their surfaces and inside the channel cannot be effectively removed, affecting equipment performance and surgical safety.

[0005] To address the aforementioned issues, a cleaning device and system for minimally invasive surgical instruments are proposed. Utility Model Content

[0054] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0055] The cleaning device for minimally invasive surgical instruments provided in this application can be applied to medical devices, such as within a device system, to clean imaging elements or other working elements through a rotatable cleaning component, thereby ensuring the working quality of the elements.

[0056] like Figure 1In some embodiments, the cleaning device includes an insertion sleeve 4 and a cleaning component 6. The insertion sleeve 4 has a hollow channel 4.2, which is suitable for arranging an endoscope insertion part and an elongated component such as a radio frequency device therein. The cleaning component 6 is disposed at the distal end of the insertion sleeve 4, and the cleaning component 6 contacts at least partially the distal end face of the insertion sleeve 4 when it rotates.

[0057] The insertion sleeve 4 has a drive shaft channel 4.1 on its side, and a retractable drive shaft 7 is provided in the drive shaft channel 4.1. The cleaning component 6 is located in the drive shaft channel 4.1 when not in use. This ensures that the cleaning component 6 is not disturbed when the insertion sleeve 4 enters the tissue, and that the cleaning component 6 does not affect operation and imaging when not in use.

[0058] like Figure 3 As shown, the cleaning component 6 is driven to rotate via a drive shaft 7. The cleaning component 6 is made of an elastic, compressible, and soft material, and the distal end of the drive shaft 7 has an elastic bending section 7.2. According to the above structure, in some embodiments, the operation steps of the device are as follows: the insertion sleeve 4 of the cleaning device is inserted into the tissue with its distal end positioned within the working space; the endoscope insertion part and radio frequency elongated components are inserted into the hollow channel 4.2; when cleaning is required, a rotational torque is applied to the drive shaft 7 to rotate the cleaning component 6. During rotation, the cleaning component 6 contacts the end face of the working part to complete the cleaning. This design, using a rotatable cleaning component to clean the endoscope lens or other working components, effectively removes dirt, blood, and other debris, ensuring that image quality is not affected and improving the accuracy and reliability of medical operations.

[0059] It is understood that the working end face can be a radio frequency electrode sheet and is not limited to the lens of the image acquisition unit.

[0060] Understandably, the insertion sheath 4 can be used with a puncture needle to create a puncture channel, or it can enter the tissue from an existing channel.

[0061] Furthermore, when the elastic bending section 7.2 is not subjected to external force, the angle between it and the transmission shaft 7 is in the range of 30° to 150°, and the size of the angle is determined by the angle of the distal end face of the insertion sleeve 4 and the setting position of the insertion sleeve 4.

[0062] In some disclosures, the distal end of the drive shaft 7 is an elastically bent section 7.2, which is a hollow spring tube. The hollow spring tube 7.2 is connected to the main body of the drive shaft 7 by welding or integral cutting. The main body of the drive shaft 7 is a metal flexible drive shaft 7, which can be a flexible metal hose, a metal wire, or a metal braided flexible shaft. The rotational torque input at the proximal end of the drive shaft 7 drives the rotation at the distal end through its transmission.

[0063] The combination of the flexible bending section, soft cleaning component, and metal drive 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 that the cleaning effect is significant. The cleaning component 6 can be made of compressible, soft materials such as sponge, rubber, or silicone. In terms of installation functionality, the cleaning component 6 has good elasticity and compressibility, enabling effective contact with the distal end face of the insertion sleeve 4 during rotation, ensuring thorough cleaning of the imaging element or other working parts. Furthermore, the soft material effectively avoids damage to the imaging element or other precision components, extending the device's lifespan.

[0064] Meanwhile, the compressible and soft material ensures that the cleaning component 6 can be stored in the drive shaft channel 4.1 when not in use, thus ensuring that it does not affect the operating space and operating field of vision, and will not cause interference when used with the puncture needle for puncture.

[0065] It is understood that the rotational torque can be controlled manually or electrically, and can be direct or indirect. As long as the drive shaft 7 is subjected to the required torque, the above function can be achieved. Those skilled in the art can eliminate some unreasonable technical solutions based on experience and existing structures.

[0066] like Figure 1 As shown, in some embodiments, the cleaning device includes a handle 1, the proximal end of the insertion sleeve 4 is disposed on the handle 1, the handle 1 is provided with an adjustment module mounting slot, the adjustment module mounting slot is connected to the proximal end of the insertion sleeve 4, and a moving component 3 and a rotating component 5 are movably installed in the adjustment module mounting slot. With this design, the moving component 3 drives the reciprocating motion of the transmission shaft 7 during use, and the rotating component 5 is used to drive the rotational motion of the transmission shaft 7.

[0067] like Figure 2 As shown, in some implementations, the adjustment module mounting slot is provided with a threaded sleeve positioning slot 1.1, and the near end face of the adjustment module mounting slot is provided with a rear stop positioning slot 1.5; the handle 1 is provided with a transmission guide slot 1.5 for installing the transmission shaft 7. The transmission guide slot 1.5 includes an open groove design located at the far end of the adjustment module mounting slot. After the transmission shaft 7 passes through the transmission shaft channel 4.1, it is inserted into the transmission guide slot 1.5 and then engages with the adjustment assembly.

[0068] The handle 1 is provided with an endoscope retaining groove 1.2 for positioning when the endoscope is inserted. It can be understood that the inserted endoscope handle is provided with a structure that cooperates with the endoscope retaining groove 1.2 for positioning.

[0069] like Figure 4 , Figure 5As shown, a threaded sleeve 8 is installed in the mounting slot of the adjustment module. The threaded sleeve 8 is generally annular. 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, thus completing the installation and positioning of the threaded sleeve 8.

[0070] It is understandable that the threaded sleeve 8 can also be limited by other existing positioning structures.

[0071] like Figure 6 , Figure 7 As shown, in some embodiments, the moving component 3 is a drive shaft 3.1, the drive shaft 3.1 is in the shape of a semi-cylinder, the drive shaft 3.1 has a drive thread 3.1.1 on its far end face, a drive handle on its near end, and an open rotation channel a3.1.3 on the drive shaft 3.1;

[0072] like Figure 10 As shown, the end face of the mounting slot for the adjustment module is provided with a rear stop block 9 and an upper stop block 10 for sealing;

[0073] like Figure 8 , Figure 9 As shown, the rear stop block 9 is semi-annular in shape with a central moving shaft channel 9.3. The moving shaft channel 9.3 has an eccentric rotating channel b9.4 connected to it on its side. The outer side of the rear stop block 9 has multiple rear stop block positioning posts 9.1, which are movably installed in the rear stop block positioning groove 1.5. The side plane of the rear stop block 9 has a rear stop block positioning groove 9.2.

[0074] This design ensures that the eccentrically positioned channel prevents excessive height difference between the transmission guide groove 1.4 and the center of the rotating component 5, thus guaranteeing smoother and more precise movement of the rotating component 5. Simultaneously, this design allows for an open mounting slot for the rotating component 5, facilitating installation and maintenance. The open design not only simplifies the assembly process but also improves the maintainability of the component, making replacement or adjustment of the rotating component 5 easier and faster. The sealing design of the rear stop 9 and the upper stop 10 effectively prevents dust and other impurities from entering the adjustment module, extending the equipment's service life.

[0075] like Figure 11As shown, the upper stop block 10 is semi-annular in shape, with multiple upper stop block retaining posts 10.2 on its outer side. An upper stop block positioning post 10.1 is located on the side plane of the upper stop block 10. During installation, the upper stop block positioning post 10.1 is movably installed within the rear stop block positioning groove 9.2. The upper stop block retaining posts 10.2 are movably installed within the rear stop block positioning groove 1.5. This design not only improves the efficiency of installation and disassembly but also significantly reduces costs through a reasonable structure and manufacturing process. Simultaneously, it enhances sealing and the long-term stability of the equipment, bringing higher efficiency, reliability, and cost-effectiveness to the use of medical devices.

[0076] In some embodiments, the adjustment module mounting slot adopts a split design, the adjustment module mounting slot includes a handle cover 2, and the lower part of the adjustment module mounting slot is provided with a handle guide rail 1.3 for mounting the handle cover 2, such as... 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 for quick disassembly and maintenance of the handle cover 2 during assembly. The cooperative design of the handle guide rail 1.3 and the handle cover guide rail 2.1 not only ensures the stable installation of the handle cover 2, but also effectively distributes the force, ensuring the strength and durability of the overall structure.

[0077] The handle cover 2 is provided with a threaded sleeve handle cover positioning groove 2.2 that 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 that has the same function as the rear stop positioning groove 1.5 and is used to install the upper stop block 10.

[0078] With this design, during installation, the drive shaft 7 is first inserted into the drive shaft channel 4.1, then the threaded sleeve is movably installed onto the handle, and then the rear stop 9, drive shaft 3.1, upper stop 10, and handle cover 2 are installed in sequence. After the rotating component 5 is inserted into the rotating channel, its far end is connected to the rear end of the drive shaft 7.

[0079] Furthermore, in some implementations, such as Figures 13-18 As shown, the rotating component 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.

[0080] 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.

[0081] The rotating channel a3.1.3 is provided with a rotating limiting groove 3.1.2;

[0082] When installing with this design, first misalign the rotating limiting ring 5.2 with the rotating limiting groove 3.1.2, insert the rotating shaft 5.1 into the installation position, rotate the rotating shaft 5.1 to make the rotating limiting ring 5.2 snap into the rotating limiting groove 3.1.2, and then complete the installation of the limiting ring 5.4;

[0083] The limiting ring 5.4 is in the shape of a semi-circular ring, and a limiting ring positioning post 5.4.1 is provided on the side plane. During installation, the limiting ring groove 5.2.1 and the limiting ring positioning post 5.4.1 cooperate with each other to complete the fixation.

[0084] like Figures 19-20 As shown, the transmission handle is semi-circular in 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 post 3.2.1 that cooperates with the transmission handle positioning groove 3.1.4 is provided on the transmission handle block 3.2. This completes the installation and fixation, and this design facilitates installation.

[0085] A minimally invasive surgical working element cleaning system includes a cleaning device and an instrument insertion section. The cleaning device includes an insertion section sheath with a hollow channel and a drive shaft channel. The hollow channel accommodates the endoscope insertion section. The drive shaft is telescopically mounted within the drive shaft channel, with a flexible bending section at its distal end and a cleaning component made of sponge or silicone installed at its distal end. In the non-operating state, the cleaning component is retracted within the drive shaft channel. During operation, the working element is cleaned through the rotation and telescopic movement of the drive shaft. The instrument insertion section is detachably connected to the hollow channel for easy installation and replacement. The instruments can be radiofrequency devices, grinding heads, planers, arthroscopes, etc., and the working elements can be blades, electrode pads, and image acquisition unit eyepieces. By installing the instrument insertion section into the hollow channel and controlling the rotation and telescopic movement of the cleaning component via a handle, rapid and efficient cleaning of the imaging elements is achieved, ensuring operational quality and preventing surgical interruption. This system has a simple structure, is easy to operate, and is suitable for various endoscopic surgical scenarios.
