Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a surgical device for ligating hemorrhoidal arteries and suspending hemorrhoidal tissue. Background Technology

[0002] With the development of medical technology, ultrasound detection technology has been widely used in the field of medical diagnosis. However, its application in the detection and treatment of hemorrhoids in the field of anorectal diseases is still in its early stages. Hemorrhoidal artery ligation is one of the most effective treatments for hemorrhoids. It involves using Doppler ultrasound to locate the hemorrhoidal artery, followed by surgical suturing to block blood flow to the hemorrhoid, causing it to shrink until the anal canal and rectal mucosa returns to normal. Traditional hemorrhoidal artery detectors can generally only be used to locate the hemorrhoidal artery and provide a ligation window for the procedure. They are generally only suitable for treating small hemorrhoids with minimal prolapse, such as stage I and II hemorrhoids. Stage III and IV hemorrhoids with more significant prolapse often require a larger and adjustable surgical window, a technical limitation that traditional hemorrhoidal artery detectors cannot fully address. In the process of researching hemorrhoidal artery ligation techniques, the applicant has provided some ultrasound detectors for cases involving large hemorrhoids and severely prolapsed hemorrhoids. For example, in Chinese Patent CN117503246A, the applicant provides a visualization positioning device for hemorrhoidal artery ligation and suspension surgery, comprising an inner cannula and an outer cannula. This device can be used not only for hemorrhoidal artery ligation but also for suturing and suspending larger hemorrhoids. However, during the research process, the applicant found that when using this device, a stable positional relationship needs to be maintained between the inner and outer cannulas during hemorrhoid ligation and suspension surgery. If the inner cannula detaches from the cavity of the outer cannula, the suspension and fixation operation is prone to failure, especially affecting the treatment of large hemorrhoids such as stage III and IV. Therefore, it is necessary to optimize the existing device and provide a product that can ensure the inner and outer cannulas do not detach during suturing and suspending prolapsed hemorrhoids and is easy to operate. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a surgical device for hemorrhoidal artery ligation and hemorrhoid suspension, comprising a cannula housing, the cannula housing being composed of an inner cannula and an outer cannula, and an ultrasonic transducer being disposed on the cannula housing. The inner cannula is movably and / or rotatably disposed within the cavity of the outer cannula. The outer cannula extends along its length and has an outer cannula operation window penetrating its sidewall, and the inner cannula extends along its length and has an inner cannula operation window penetrating its sidewall. The outer cannula operation window and the inner cannula operation window can be moved or rotated so that they are in opposite positions, forming a ligation window; or, the outer cannula operation window and the inner cannula... The operating window of the tube can be moved or rotated so that the opening directions of the outer tube operating window and the inner tube operating window at least partially overlap at one operating window position to form a hemorrhoid suspension and fixation operating window. The outer tube includes a closed distal end and a flared proximal end. The inner tube includes an open distal end and a flared proximal end, the shape of which is consistent with the proximal end of the outer tube. A rotating fixing part is provided on the proximal end of the outer tube and / or the proximal end of the inner tube. The rotating fixing part allows the inner tube to rotate within the cavity of the outer tube and rotatably fixes the inner tube within the cavity of the outer tube, preventing the inner tube from moving along the length direction of the outer tube.

[0004] As a preferred embodiment of the present invention, the rotating fixing part includes an elastic telescopic component disposed on the proximal end of the outer sleeve and a fixing groove disposed on the outer wall of the proximal end of the inner sleeve, the fixing groove being disposed along the circumferential direction of the outer wall of the proximal end of the inner sleeve; the elastic telescopic component can prevent the inner sleeve from moving along the length direction of the outer sleeve through the fixing groove.

[0005] As a preferred embodiment of the present invention, an outer edge component is provided on the proximal end of the outer sleeve, on a plane substantially perpendicular to the length direction of the outer sleeve. The outer edge component has a plurality of elastic telescopic component mounting cavities, and the elastic telescopic components are disposed within these cavities. Each elastic telescopic component mounting cavity has a fixing hole penetrating the sidewall of the outer sleeve and an operating hole penetrating the top of the outer edge component. A fixing plate is disposed within the elastic telescopic component mounting cavity. The end of the fixing plate facing the cavity of the outer sleeve passes through the fixing hole and connects to the cavity of the outer sleeve. A lever is provided at the top of the fixing plate, and the lever extends out of the elastic telescopic component mounting cavity through the operating hole. The fixing plate is movably mounted within the elastic telescopic component mounting cavity by a telescopic spring and slides within the elastic telescopic component mounting cavity via the lever extending out of the cavity.

[0006] As a preferred embodiment of the present invention, an outer edge component is provided on the proximal end of the outer sleeve in a plane substantially perpendicular to the length direction of the outer sleeve. An annular mounting cavity is provided on the outer edge component. A movable fixing member matching the shape of the annular mounting cavity is rotatably provided in the annular mounting cavity. The movable fixing member can rotate within the annular mounting cavity. A plurality of fixing protrusion mounting holes penetrating the sidewall of the cavity of the outer sleeve are provided on the sidewall of the annular mounting cavity. A fixing protrusion is slidably provided in the fixing protrusion mounting hole by means of a telescopic spring. The fixing protrusion extends through the fixing protrusion mounting hole and out of the inner wall of the proximal end of the outer sleeve, and engages with the fixing groove on the outer wall of the proximal end of the inner sleeve, for fixing the inner sleeve in the cavity of the outer sleeve and preventing the inner sleeve from moving along the length direction of the outer sleeve.

[0007] As a preferred embodiment of the present invention, the movable fixing member has an annular region and a region with a gradually changing width. The annular region can compress the telescopic spring to elastically deform into the cavity of the outer sleeve along the radial direction of the outer sleeve, thereby causing the fixing protrusion to extend into the cavity of the outer sleeve and to snap into the fixing groove on the near end outer wall of the inner sleeve.

[0008] As a preferred embodiment of the present invention, a stop protrusion is provided on the mounting hole of the fixed protrusion facing the inner side of the cavity of the outer sleeve. A groove extending along its length is provided on one side of the fixed protrusion. The groove has a closed port and an open port at the other end. The telescopic spring is disposed in the groove, with one end in contact with the stop protrusion and the other end in contact with the closed port of the groove.

[0009] As a preferred embodiment of the present invention, the outer edge component is provided with a notched cavity body connected to the annular mounting cavity, and the movable fixing member is provided with a lever, which extends through the notched cavity body and out of the outer side wall of the outer edge component, and the movable fixing member is rotated in the annular mounting cavity by means of the lever.

[0010] As a preferred embodiment of the present invention, the outer edge component is provided with an annular mounting cavity cover plate for mounting the movable fixing member in the annular mounting cavity.

[0011] As a preferred embodiment of the present invention, a guide groove is provided on the annular mounting cavity cover plate at a position corresponding to the fixed protrusion, and the telescopic spring is at least partially disposed in the guide groove to guide the telescopic direction of the telescopic spring.

[0012] As a preferred embodiment of the present invention, an outer edge component is provided on the proximal end of the outer sleeve in a plane substantially perpendicular to the length direction of the outer sleeve. The outer edge component has a plurality of fixing protrusion mounting holes penetrating the proximal sidewall of the outer sleeve. A fixing protrusion is slidably disposed within each fixing protrusion mounting hole via a spring. The fixing protrusion extends through the fixing protrusion mounting hole and out of the proximal inner wall of the outer sleeve, and can engage with a fixing groove on the proximal outer wall of the inner sleeve. The rotating fixing part further includes a rotating fastener, which is rotatably connected to the outer edge component. When the rotating fastener rotates, it contacts the spring to cause the spring to undergo elastic deformation.

[0013] As a preferred embodiment of the present invention, the outer edge of the outer component is provided with a plurality of protrusions extending outward to the outer side of the outer sleeve, and the protrusions are provided with elastic components, which are in elastic contact with the rotating fastener to rotatably and fixedly connect the outer edge component and the rotating fastener.

[0014] As a preferred embodiment of the present invention, the rotating fastener has a hollow annular structure, and the inner surface of the rotating fastener is provided with the same number of arc-shaped notches as the protrusions. The inner surface of the rotating fastener is also provided with the same number of arc-shaped protrusions as the fixed protrusions. The arc-shaped protrusions include a second width gradient portion. The fixed protrusions contact the inner surface of the arc-shaped protrusions through the elastic deformation of the spring.

[0015] As a preferred embodiment of the present invention, an arc-shaped groove is provided in the arc-shaped notch along the thickness direction; the elastic component includes a fixing spring and a fixing rod, the fixing spring and the fixing rod are installed in the fixing rod fixing hole on the outer edge of the outer edge component; the fixing rod extends into the arc-shaped groove by the action of the fixing spring, so as to rotatably and fixedly connect the outer edge component to the rotating fastener.

[0016] The technical solution provided by this invention has the following advantages compared with existing related products and solutions:

[0017] 0017 The present invention optimizes and improves the structure of the inner and outer sleeves of the hemorrhoidal artery ligation and hemorrhoid suspension surgical device. A fixing groove is provided on the proximal outer wall of the inner sleeve, and a corresponding elastic telescopic component is provided on the proximal end of the outer sleeve. The inner and outer sleeves can be connected by the elastic telescopic component and the fixing groove, fixing the inner and outer sleeves together. This ensures that the two can rotate relative to each other, while also preventing them from detaching during the operation and affecting the safety of the operation.

[0018] Secondly, the present invention further optimizes and improves the relevant features of the elastic telescopic component of the outer sleeve. An extension component is provided on the proximal end of the outer sleeve, and the elastic telescopic component is set in the extension component. Corresponding operating holes, fixing holes and other structures are provided. The sliding of the fixing piece is controlled by the lever, so that it can extend out of the fixing hole or retract into the fixing hole as needed, thereby realizing the snap-locking between the outer sleeve and the inner sleeve, ensuring that the two are snap-locked, and the fixing piece can be opened by the lever when rotated to any position, so that the inner and outer sleeves can be separated from each other.

[0019] Furthermore, this invention further optimizes and improves the features of the elastic telescopic component of the outer sleeve. An annular mounting cavity and a corresponding movable fixing member are provided on the outer edge component. By setting the shape and structure of the movable fixing member and the fixing protrusions in the annular mounting cavity, the number of levers in the above scheme is reduced. Only one lever on the movable fixing member is needed to slide two or more fixing protrusions in the annular mounting cavity, thereby realizing the mutual unlocking and separation of the inner sleeve and the outer sleeve. This effectively reduces the difficulty of operation and enhances the applicability of the device.

[0020] Furthermore, the present invention further optimizes and improves the features of the elastic telescopic component of the outer sleeve, integrating the annular mounting cavity cover plate, movable fixing component and other components in the above solution into the rotating fastener. While achieving the same function as the above solution, the lever in the solution is further removed. The locking and unlocking separation of the inner sleeve and outer sleeve is achieved by rotating the rotating fastener, further reducing the difficulty of operation and improving the processing and production performance.

Detailed Implementation

[0038] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0039] In this invention, unless otherwise explicitly specified and limited, terms such as "installation," "fixing," and "connection" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components. Furthermore, terms such as "inner," "outer," and "length direction," which indicate a certain orientation or positional relationship, are intended to indicate the orientation or positional relationship based on the accompanying drawings. They are only for the convenience of describing the scheme of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] 0040 This invention provides a surgical device for hemorrhoidal artery ligation and hemorrhoid suspension, comprising a cannula housing, the cannula housing being composed of an inner cannula and an outer cannula, an ultrasonic transducer being disposed on the cannula housing, the inner cannula being movably and / or rotatably disposed within the cavity of the outer cannula; the outer cannula having an operating window extending along its length through its sidewall, and the inner cannula having an operating window extending along its length through its sidewall; the operating windows of the outer cannula and the inner cannula being movable or rotatable. The outer sleeve operating window and the inner sleeve operating window can be rotated to be in opposite positions, forming a ligation window; alternatively, the outer sleeve operating window and the inner sleeve operating window can be moved or rotated so that the opening directions of the outer sleeve operating window and the inner sleeve operating window at least partially overlap at one operating window position to form a hemorrhoid suspension and fixation operating window; the placement of the ultrasonic transducer is not specifically limited in this invention. To ensure more precise ligation and suturing of the hemorrhoidal artery, the ultrasonic transducer is placed at the edge of the inner sleeve operating window; see attached figure. Figure 2 In this invention, the ligation window refers to the inner sleeve being rotated within the outer sleeve cavity so that the outer sleeve operation window and the inner sleeve operation window are in opposite positions. This relative position primarily refers to the two operation windows facing opposite directions. The inner sleeve is shorter than the outer sleeve. When the inner sleeve is installed within the outer sleeve cavity, a ligation window is formed between the distal edges of the inner sleeve operation window and the distal edges of the outer sleeve operation window. The alignment of the distal edges of the inner sleeve operation window and the outer sleeve operation window can be adjusted by adjusting the length of the inner sleeve. The distance between the distal edges of the opening is adjusted to adjust the height of the ligation window. In this invention, the hemorrhoid suspension and fixation operation window is formed by at least partially overlapping the opening directions of the outer sleeve operation window and the inner sleeve operation window at at least one operation window position. When the overlap of the two operation windows is small, the hemorrhoid suspension and fixation operation window is relatively small. When the two operation windows face the same direction, the windows completely overlap, and the hemorrhoid suspension and fixation operation window reaches its maximum size. The size of the hemorrhoid suspension and fixation operation window can be adjusted by rotating the inner sleeve inside the outer sleeve cavity.

[0041] In this invention, the outer sleeve includes a closed distal end 011 and a flared proximal end 012; the inner sleeve includes an open distal end 021 and a flared proximal end 023, the shape of which is consistent with that of the proximal end 012 of the outer sleeve. "Consistent" means that the shape and size of the proximal end of the inner sleeve are substantially the same as those of the proximal end of the outer sleeve, allowing the proximal end of the inner sleeve to fit snugly against the proximal end of the outer sleeve when the inner sleeve is installed on the outer sleeve. A rotating fixing part 013 is provided on the proximal end 012 of the outer sleeve and / or the proximal end 023 of the inner sleeve. The rotating fixing part 013 allows the inner sleeve to rotate within the cavity of the outer sleeve, rotatably fixing the inner sleeve within the cavity of the outer sleeve and preventing the inner sleeve from moving along the length of the outer sleeve. The rotatable fixing described in this invention means that the inner sleeve and the outer sleeve can be in a fixed state in the length direction, that is, the two do not separate, but the inner sleeve can rotate within the cavity of the outer sleeve, that is, it can rotate on a horizontal plane that is substantially perpendicular to the length direction of the inner and outer sleeves.

[0042] 0042 In some embodiments of the present invention, the rotating fixing part 013 includes an elastic telescopic component disposed on the proximal end of the outer sleeve and a fixing groove 024 disposed on the outer wall of the proximal end of the inner sleeve. The fixing groove 024 is disposed along the circumferential direction of the outer wall of the proximal end of the inner sleeve. The elastic telescopic component can prevent the inner sleeve from moving along the length direction of the outer sleeve through the fixing groove 024. In the present invention, the elastic telescopic component and the fixing groove are interconnected components. When the inner sleeve is installed in the cavity of the outer sleeve and both are in a locked state (i.e., a rotating fixed state), the elastic telescopic component and the fixing groove are in a snap-fit ​​fixed state. The elastic telescopic component is stuck in the fixing groove, thereby restricting the outer sleeve to rotate only along the fixing groove. When needed, when the inner sleeve and the outer sleeve are disengaged from the locking device, the elastic telescopic component extends out of the fixing groove through elastic deformation, thereby detaching the inner sleeve and the outer sleeve from the fixing. The size of the fixing groove and the elastic telescopic component in the present invention can be adjusted accordingly as needed.

[0043] 0043 can be found in the appendix. Figure 3 In some preferred embodiments of the present invention, an outer edge component (see Appendix) is provided on the proximal end 012 of the outer sleeve in a plane substantially perpendicular to the length direction of the outer sleeve. Figure 1The outer edge component has a plurality of elastic telescopic component mounting cavities 019 (two ear-shaped structures). The number of elastic telescopic component mounting cavities 019 is not specifically limited in this invention, but two or more are preferred. More preferably, two or more elastic telescopic component mounting cavities are evenly distributed in relative positions. The elastic telescopic component is disposed within the elastic telescopic component mounting cavity 019. The elastic telescopic component mounting cavity 019 has a fixing hole 015 penetrating the side wall of the outer sleeve and an operating hole 014 penetrating the top of the outer edge component. A fixing piece 017 is disposed within the elastic telescopic component mounting cavity 019. The left end of the fixing piece 017 extends through the fixing hole 015 into the hollow part of the outer sleeve. Inside the cavity, the piece protrudes into the cavity of the outer sleeve and can contact and snap together with the fixing groove of the inner sleeve, achieving rotatable fixation. A lever is provided on the top of the fixing piece 017. The lever extends out of the elastic telescopic component mounting cavity 019 through the operating hole 014. In this invention, the lever and the fixing piece can be integrally formed or other fixing and installation methods can be used. The lever is mainly used to drive the fixing piece to slide in the elastic telescopic component mounting cavity, thereby causing the fixing piece to extend / retract into the fixing hole. The fixing piece 017 is movably installed in the elastic telescopic component mounting cavity 019 through the telescopic spring 016, and slides in the elastic telescopic component mounting cavity 019 through the lever extending out of the elastic telescopic component mounting cavity 019.

[0044] See appendix Figure 4 , 5In another embodiment of the present invention, an outer edge component is provided on the proximal end 012 of the outer sleeve, which is substantially perpendicular to the length direction of the outer sleeve. This outer edge component can be annular in shape, and an annular mounting cavity 101 is provided on the outer edge component. Further, the annular mounting cavity can be a complete annular shape or a semi-annular shape, adjustable according to the shape and size of the movable fixing member 102. A movable fixing member 102, matching the shape of the annular mounting cavity 101, is rotatably provided within the annular mounting cavity 101. The movable fixing member 102 can rotate within the annular mounting cavity 101. The annular mounting cavity 101 faces the cavity side of the outer sleeve. The sidewall is provided with a plurality of fixing protrusion mounting holes that penetrate one side of the cavity of the outer sleeve. In this invention, the number of fixing protrusion mounting holes is not specifically limited, but two or more are preferred. More preferably, two or more fixing protrusion mounting holes are evenly distributed in relative positions. Each fixing protrusion mounting hole is slidably provided with a fixing protrusion 104 through a telescopic spring 016. The fixing protrusion 104 extends through the fixing protrusion mounting hole and protrudes from the inner wall of the proximal end 012 of the outer sleeve, and engages with the fixing groove 024 on the outer wall of the proximal end of the inner sleeve, so as to fix the inner sleeve in the cavity of the outer sleeve and prevent the inner sleeve from moving along the length direction of the outer sleeve.

[0045] Furthermore, the movable fixing member 102 has a width-gradient region, which can compress the telescopic spring 016 to elastically deform along the radial direction of the outer sleeve. The annular mounting cavity 101 is annular in shape, with the distance between the inner and outer rings being substantially the same; the width of the width-gradient region of the movable fixing member 102 refers to the... Figure 5 The wide filling strip of the movable fixing member, due to the existence of a width-gradient area, causes a portion of the movable fixing member 102 (e.g., attached) to rotate within the annular mounting cavity. Figure 5 One end of the movable fixing member 102 is tightly attached to the edge of the annular mounting cavity. A portion of the cavity is narrower than the annular mounting cavity, creating a gap area 1040. This gap area allows the elastic spring 016 to cause the fixing protrusion to enter the spring, thus unlocking and separating the inner and outer sleeves. (See attached diagram.) Figure 5 and 7 The location and number of the width gradient area are consistent with the location of the fixed protrusion mounting holes, so that when the movable fixing member 102 is rotated, the telescopic springs in all the fixed protrusion mounting holes are simultaneously compressed or released.

[0046] For further details, please see the appendix. Figure 5The outer edge component is provided with a notch 109 connected to the annular mounting cavity 101. The movable fixing member 102 is provided with a lever 103, which extends through the notch 109 and outwards from the outer wall of the outer edge component. The lever 103 causes the movable fixing member 102 to rotate within the annular mounting cavity 101. In this invention, the length of the notch 109 is not specifically limited and can be adjusted according to actual needs, as long as the lever 103 can rotate normally within it, and the movable fixing member 102 can release the telescopic spring through its width-gradient area, and also compress the telescopic spring in the area where the movable fixing member is in close contact with the annular mounting cavity, thereby achieving the locking and unlocking of the inner and outer sleeves. Further, see the appendix. Figure 6 The outer edge component is provided with an annular mounting cavity cover plate 107 for installing the movable fixing member 102 inside the annular mounting cavity 101. Further, a guide groove 108 is provided on the annular mounting cavity cover plate 107 at a position corresponding to the fixing protrusion 104. The telescopic spring 016 is at least partially disposed in the guide groove 108 to guide the extension and retraction direction of the telescopic spring 016. In this embodiment, the movable fixing member 102 and the outer edge component are independent components. The movable fixing member 102 can be manufactured separately and installed inside the annular mounting cavity 101, and then sealed with the annular mounting cavity cover plate 107. The specific sealing method is not particularly limited; screws, bolts, or adhesives can be used for fixing.

[0047] In another embodiment of the present invention, see Appendix Figure 12The outer sleeve has an outer edge component on its proximal end, which is substantially perpendicular to the length direction of the outer sleeve. The outer edge component has several mounting holes for fixing protrusions penetrating the proximal sidewall of the outer sleeve. A fixing protrusion is slidably disposed within each mounting hole via a spring. The fixing protrusion extends through the mounting hole to the inner wall of the proximal end of the outer sleeve and can engage with a fixing groove on the outer wall of the proximal end of the inner sleeve. The rotating fixing part also includes a rotating fastener, which is rotatably connected to the outer edge component. When the rotating fastener rotates, it contacts the spring, causing the spring to elastically deform. Furthermore, the outer edge of the outer edge component has several protrusions extending outwards from the outer sleeve. Each protrusion has an elastic component that elastically contacts the rotating fastener, thereby rotatably fixing the outer edge component to the rotating fastener. Furthermore, the rotating fastener has a hollow annular structure, and its inner surface has the same number of arc-shaped notches as the protrusions. The inner surface of the rotating fastener also has the same number of arc-shaped protrusions as the fixing protrusions, each arc-shaped protrusion including a second width gradient portion. The fixing protrusion contacts the inner surface of the arc-shaped protrusions through the elastic deformation of the spring. Furthermore, an arc-shaped groove is provided along the thickness direction within the arc-shaped notch. The elastic component includes a fixing spring and a fixing rod, which are installed in a fixing rod fixing hole on the outer edge of the outer edge component. The fixing rod extends into the arc-shaped groove under the action of the fixing spring, thereby rotatably and fixedly connecting the outer edge component to the rotating fastener.

[0048] The present invention will now be described in detail through embodiments. It should be noted that the following embodiments are only for further illustration of the present invention and should not be construed as limiting the scope of protection of the present invention. Non-essential improvements and adjustments made by those skilled in the art based on the above description of the present invention still fall within the scope of protection of the present invention.

[0049] See appendix Figures 1-3This embodiment provides a surgical device for hemorrhoidal artery ligation and hemorrhoid suspension, comprising a cannula housing, which is composed of an inner cannula and an outer cannula. An ultrasonic transducer is disposed on the cannula housing. The inner cannula is movably and / or rotatably disposed within the cavity of the outer cannula. The outer cannula has an operating window extending along its length, penetrating the sidewall of the outer cannula. The inner cannula also has an operating window extending along its length, penetrating the sidewall of the inner cannula. The operating windows of the outer and inner cannsulas can be moved or rotated to position them in opposite directions, forming a ligation window; or, the operating windows of the outer and inner cannsulas can be... The device is movable or rotatable such that the opening directions of the outer sleeve operating window and the inner sleeve operating window at least partially overlap at one operating window position to form a hemorrhoid suspension and fixation operating window.
