Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endoscope operating part and an endoscope. Background Technology

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, software and other technologies. It includes an image sensor, optical lens, light source illumination, water and air control, etc. It can enter the stomach through the mouth or other natural orifices into the body. Endoscopes can be used to see lesions that cannot be seen by X-rays and other medical equipment.

[0003] Doctors and other users operate the endoscope's control unit to perform actions such as advancing and bending the endoscope. Endoscopes with functions such as zooming, magnification, and forceps lifting are also equipped with a push rod and a rotating disk fixedly connected to the push rod on the control unit. The push rod drives the rotating disk to achieve functions such as zooming, magnification, and forceps lifting.

[0004] In existing endoscope operating units, a rotating disk is mounted on a drum seat, located between the drum seat and the housing of the endoscope operating unit, and is capable of rotating around the drum seat relative to the housing of the endoscope operating unit. Sealing components are provided between the rotating disk and the drum seat, and between the rotating disk and the housing, to seal the interior and exterior of the endoscope operating unit.

[0005] However, the housing of the endoscope operating unit is made of resin, which is susceptible to deformation during installation and use. Especially in existing endoscope operating units, when the rotating disk is rotated by a push rod fixed to it, force is applied only to one side of the disk, resulting in an asymmetrical driving force and higher requirements for sealing and resistance. Deformation of the endoscope operating unit housing will hinder disk rotation and reduce operability. Furthermore, the sealing member is directly pressed between the outer circumferential surface of the rotating disk and the inner circumferential surface of the mounting hole in the housing. If the endoscope operating unit housing deforms, the force applied to the sealing member will change during disk rotation, compromising sealing reliability and potentially leading to leakage. These problems pose a serious challenge to the reliability and lifespan of the endoscope operating unit. Summary of the Invention

[0006] In order to solve at least one of the problems existing in the prior art, the present invention provides an endoscope operating part and an endoscope, the purpose of which is that even if the housing of the endoscope operating part is deformed, the endoscope operating part can maintain good operability and reliable sealing.

[0007] To achieve the above objectives, one embodiment of the present invention is an endoscope operating unit, comprising: a housing; a drum seat fixed inside the housing and protruding from a mounting hole on the housing to the outside of the housing; a rotating disk mounted on the drum seat, sealing with the drum seat and rotatable around the drum seat; and a separating member disposed between the inner wall of the mounting hole of the housing and the outer peripheral surface of the rotating disk, separating the housing from the rotating disk, wherein the separating member is sealed with both the housing and the rotating disk, and remains stationary relative to the housing when the rotating disk rotates.

[0008] Preferably, the separating member is integrally formed with the drum seat, the drum seat has a support plate, the support plate connects the separating member and the drum seat, and the rotating disk is installed in the space defined by the support plate, the separating member and the drum seat, and is supported by the support plate.

[0009] Preferably, the separating member is separately disposed from the drum seat.

[0010] Preferably, the drum seat is provided with a support portion that protrudes radially outward, the support portion being used to support the rotating disk.

[0011] Preferably, the drum seat is provided with a limiting part, which limits the angle at which the rotating disk rotates around the drum seat.

[0012] Preferably, the bulk modulus of the separating member is greater than that of the shell.

[0013] Preferably, the partition member, the rotating disk, and the drum seat are made of the same material.

[0014] Preferably, the drum seat and the housing are fixed on the same fixing plate.

[0015] Another embodiment of the present invention is an endoscope having the endoscope operating section described in any of the above claims.

[0016] Therefore, according to the endoscope operating unit and endoscope of the present invention, a separating member is used to separate the housing of the endoscope operating unit from the rotating disk. Thus, even if the housing of the endoscope operating unit deforms, the rotation of the rotating disk will not be affected, and the endoscope operating unit can maintain good operability. Furthermore, when the rotating disk rotates, the separating member remains stationary relative to the housing. Therefore, the seal between the housing of the endoscope operating unit and the separating member is a static seal. Even if the housing of the endoscope operating unit deforms, the seal between the housing of the endoscope operating unit and the separating member will not be affected by the rotation of the rotating disk, and the endoscope operating unit can maintain reliable sealing.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this disclosure clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0027] The endoscope of this invention comprises an operating section, an insertion section, and an endoscope lens endpiece located at the front end of the insertion section. The operating section is used to operate the endoscope, such as performing operations like advancement, bending of the insertion section, zooming and magnification of the optical system, and raising and lowering of the forceps. The insertion section is inserted into the body and has a connecting channel and an instrument channel connecting the operating section and the endoscope lens endpiece. The endoscope of this invention has at least one of the functions of magnification, zooming, and forceps lifting, and a rotating disk for realizing these functions is provided in the operating section of the endoscope.

[0028] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0029] <First Implementation Method>

[0030] Figure 1 This is an exploded perspective view of the endoscope operating section according to the first embodiment of the present invention. Figure 2 This is a top view of the endoscope operating section according to the first embodiment of the present invention. Figure 3 This is a bottom view of the endoscope operating section according to the first embodiment of the present invention.

[0031] like Figure 1 As shown, the endoscope operating unit of this embodiment includes a push rod 1, a pressure plate 2, a rotating plate 3, a drum seat 4, a housing 5, a fixing plate 6, and a linkage mechanism 7.

[0032] like Figure 2 As shown, push rod 1 is fixed to the surface of rotating disk 3, and the user pushes push rod 1 to make rotating disk 3 rotate. Alternatively, in this embodiment, push rod 1 may not be provided, and rotating disk 3 may be driven by a motor or the like.

[0033] The pressure plate 2 is fixed to the surface of the drum seat 4 via the rotating disk 3 to prevent the rotating disk 3 from detaching from the drum seat 4. When the pressure plate 2 is fixed to the surface of the drum seat 4, a gap exists between the pressure plate 2 and the rotating disk 3 to prevent the pressure plate 2 from interfering with the rotation of the rotating disk 3. Alternatively, in this embodiment, other structures can be provided to prevent the rotating disk 3 from detaching from the drum seat 4, such as a limiting structure on the drum seat 4.

[0034] The rotating disk 3 is mounted on the drum seat 4, and a sealing member 91 is provided between the rotating disk 3 and the drum seat 4 to ensure that the rotating disk 3 and the drum seat 4 remain sealed. The rotating disk 3 can rotate around the drum seat 4. By rotating the rotating disk 3, the magnification assembly, zoom assembly, or lifting clamp assembly of the endoscope can be activated.

[0035] The drum seat 4 is fixed inside the housing 5 and protrudes from the mounting hole 51 on the housing 5 to the outside of the housing 5. The drum seat 4 is a component used to mount rotating parts such as handwheels and rotating disks 3 (not shown), and is made of a material that is not easily deformed.

[0036] The housing 5 has a space for accommodating the rotating disk 3, the drum seat 4, etc., and has mounting holes 51, button mounting parts 52, and openings 53 for cables, fixing plates 6, linkage mechanisms 7, etc. to protrude from the housing 5 toward the insertion part.

[0037] The fixing plate 6 extends into the interior of the housing 5 through the opening 53 of the housing 5, and is used to fix the drum seat 4 and the housing 5. That is, in this embodiment, the drum seat 4 and the housing 5 are both fixed on the same fixing plate 6.

[0038] like Figure 3 As shown, the linkage mechanism 7 is located inside the housing 5 and is connected to the rotating disk 3. It converts the rotational motion of the rotating disk 3 into linear motion, thereby driving the magnification component, zoom component, or lifting forceps component of the endoscope to perform actions.

[0039] Specifically, the linkage mechanism 7 includes a fixed block 71, a pin 72, a slider 73, and a connecting rod. The fixed block 71 is fixed to the rotating disk 3, and the connecting rod is rotatably connected to the fixed block 71 via the pin 72, and is also rotatably connected to the slider 73. When the rotating disk 3 rotates, the fixed block 71 rotates together, and drives the slider 73 to move linearly via the connecting rod. This converts the rotational motion of the rotating disk 3 into the linear motion of the slider 73.

[0040] It should be noted that although the linkage mechanism 7 is selected as the motion conversion mechanism in the above description, other forms of motion conversion mechanisms such as lead screws and racks and pinions can also be used in this embodiment. In addition, in this embodiment, a drive mechanism such as a chain or wire rope can be directly connected to the rotating disk 3, and the rotation of the rotating disk 3 can directly drive the magnification component, zoom component, or lifting clamp component of the endoscope through gear meshing, belt drive structure, etc.

[0041] Next, refer to Figure 4 , Figure 5 The drum seat 4 of this embodiment will be described.

[0042] Figure 4 This is a cross-sectional view of the endoscope operating section according to the first embodiment of the present invention. Figure 5 This is a perspective view of the drum seat according to the first embodiment of the present invention.

[0043] like Figure 4-5 As shown, in this embodiment, a partition member 8A is integrally formed on the drum seat 4.

[0044] like Figure 4 As shown, the separating member 8A is disposed between the inner wall of the mounting hole 51 of the housing 5 and the rotating disk 3, separating the housing 5 from the rotating disk 3.

[0045] A sealing member 92 is provided between the partition member 8A and the rotating disk 3, and a sealing member 93 is provided between the partition member 8A and the housing 5, thereby keeping the partition member 8A sealed to the housing 5 and the rotating disk 3. Furthermore, since the partition member 8A is integrally formed with the drum seat 4, the partition member 8A remains stationary relative to the housing 5 when the rotating disk 3 rotates around the drum seat 4.

[0046] Therefore, according to this embodiment, the housing 5 of the endoscope operating unit is separated from the rotating disk 3 by the partition member 8A. Thus, even if the housing 5 of the endoscope operating unit is deformed, the rotation of the rotating disk 3 will not be affected, and the endoscope operating unit can maintain good operability.

[0047] Furthermore, in this embodiment, the dynamic seal between the rotating disk 3 and the housing 5 in the prior art is replaced by the static seal between the separating member 8A and the housing 5. Even if the housing 5 of the endoscope operating part is deformed, the sealing member 93 will not be affected by the rotating disk 3 and can still maintain good sealing performance. Therefore, the endoscope operating part can also maintain reliable sealing performance.

[0048] Preferably, such as Figure 4-5 As shown, the drum seat 4 also has a support plate 41. The support plate 41 connects the partition member 8A to the main body of the drum seat 4. The rotating disk 3 is installed within the space (rotation space) defined by the support plate 41, the partition member 8A, and the main body of the drum seat 4, and is supported by the support plate 41. This configuration allows for a more compact structure of the endoscope operating unit, helping to reduce its volume.

[0049] Preferably, such as Figure 5 As shown, a limiting part (a first limiting part 42 and a second limiting part 43) is also provided on the drum base 4. The limiting part restricts the rotation angle of the rotating disk 3 relative to the drum base 4. Specifically, as... Figure 5 As shown, the support plate 41 is located below the partition member 8A. To fix the connecting rod assembly 7 to the rotating disk 3 below the partition member 8A, the support plate 41 is only partially connected to the partition member 8A. The support plate 41 has a first limiting portion 42 and a second limiting portion 43 at both ends. The first limiting portion 42 and the second limiting portion 43 abut against the fixing block 71 fixed to the rotating disk 3 to limit the rotation angle of the rotating disk 3 relative to the drum seat 4. This prevents excessive rotation of the rotating disk 3 from damaging the endoscope's magnifying assembly, zoom assembly, and lifting clamp assembly.

[0050] Alternatively, other types of limiting parts can be used in this embodiment. For example, a limiting groove can be provided on the drum seat 4 as a limiting part, and a protrusion can be provided on the rotating disk 3. The protrusion rotates within the limiting groove, and the rotation angle of the rotating disk 3 is limited by setting the length of the limiting groove. Of course, the above-mentioned limiting groove can also be provided on the partition member 8A.

[0051] Preferably, the bulk modulus of the partition member 8A is greater than that of the housing 5. In other words, compared to the housing 5 made of resin or plastic, the partition member 8A is made of a material that is less prone to deformation, such as high-strength stainless steel. Therefore, even if the housing 5 deforms, the partition member 8A can withstand the compressive stress generated by the deformation of the housing 5 and maintain its original shape, thereby ensuring the rotation space of the rotating disk 3 and reliably preventing the deformation of the housing 5 from affecting the operability of the endoscope operating part.

[0052] Preferably, the partition member 8A, the rotating disk 3, and the drum seat 4 are made of the same material. Further, the partition member 8A, the rotating disk 3, and the drum seat 4 are made of the same wear-resistant material. In this way, when the rotating disk 3 rotates, the wear rates of the partition member 8A, the rotating disk 3, and the drum seat 4 are approximately the same, preventing any one of them from wearing out too quickly and causing seal failure.

[0053] Preferably, in this embodiment, the central axes of the rotating disk 3, the partition member 8A, and the drum seat 4 coincide, that is, in the endoscope operating unit of this embodiment, the rotating disk 3, the partition member 8A, and the drum seat 4 are coaxially arranged. This ensures that the rotation axis of the rotating disk 3 remains stable during rotation, making the rotation of the rotating disk 3 smoother and improving the operability of the endoscope operating unit. Furthermore, as long as the rotating disk 3 can rotate between the outer periphery of the drum seat 4 and the inner periphery of the partition member 8A, there are no particular limitations on the rotating disk 3, the drum seat 4, and the partition member 8A. For example, the radial outer periphery of the partition member 8A can be various shapes such as polygonal or circular.

[0054] Furthermore, in this embodiment, the drum seat 4 and the partition member 8A are integrally formed, thus ensuring that the drum seat 4 and the partition member 8A have the same central axis. Simply setting the rotating disk 4 to an annular shape allows the central axes of the rotating disk 3, the partition member 8A, and the drum seat 4 to coincide. Therefore, according to this embodiment, the operability of the endoscope operating unit can be improved through a simpler structure.

[0055] <Second Implementation Method>

[0056] Below, refer to Figure 6 The second embodiment of the present invention will be described.

[0057] In this embodiment, the biggest difference from the first embodiment is that the separating member 8B and the drum seat 4 are separately arranged, that is, the separating member 8B and the drum seat 4 are two independent components. This increases the freedom of component design, facilitates the installation of the rotating disk 3, and improves production efficiency.

[0058] In addition, such as Figure 6 As shown, the drum seat 4 is provided with a support portion 44 protruding radially outward, which supports the rotating disk 3. Therefore, when installing the rotating disk 3, it is only necessary to place the rotating disk 3 on the support portion 44, which simplifies the installation process of the rotating disk 3, facilitates the assembly of the endoscope operating part, and improves production efficiency.

[0059] Although not illustrated, the partition member 8B can be fixed to the base plate 6, and remains stationary relative to the housing 5 when the rotating disk 3 rotates around the drum seat 4. Furthermore, by fixing both the partition member 8B and the drum seat 4 to the same base plate 6, it can be ensured that the drum seat 4 and the partition member 8B have the same central axis. Simply forming the rotating disk 4 into a ring shape allows the central axes of the rotating disk 3, the partition member 8B, and the drum seat 4 to coincide, thus improving the operability of the endoscope operating unit through a simple structure.

[0060] Furthermore, in this embodiment, the partition member 8B can also be fixed to the housing 5 by means of insert molding or the like, so that the partition member 8B remains stationary relative to the housing 5 when the rotating disk 3 rotates around the drum seat 4. Since the housing 5 and the drum seat 4 are both fixed on the same base plate 6, it can also be ensured that the drum seat 4 and the partition member 8B have the same central axis.

[0061] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units.
