Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to an arthroscope. Background Technology

[0002] Arthroscopic surgery, a key technique in the field of surgery, has been widely used in procedures involving the knee, shoulder, and wrist joints. A traditional arthroscopy system typically consists of three main components: an optical endoscope, an imaging system, and a cold light source system. The optical endoscope relies on a complex lens array to capture images of the inside of the joint, the imaging system transmits the captured images to a display screen for the surgeon to observe, and the cold light source system provides illumination for the surgical area.

[0003] Traditional arthroscopic systems, despite their significant achievements, suffer from numerous inconveniences due to their wired connections. Cables not only increase the operator's workload, leading to hand fatigue and decreased operational precision, but also limit the range of motion of the arthroscope within the joint, hindering the use of other surgical instruments. This limitation is particularly pronounced in surgeries requiring high flexibility and precision. While related technologies have disclosed wired arthroscopes with retractable lenses to reduce cable inconvenience, the problem of cable fatigue damage during arthroscope movement remains unresolved, consequently affecting stable signal transmission and reducing the effectiveness of arthroscopy.

[0004] As can be seen from the above, the use of arthroscopy in the existing technology suffers from poor performance due to the influence of cables. Summary of the Invention

[0005] The main objective of this invention is to provide an arthroscope that solves the problem of poor performance caused by the interference of cables during the use of arthroscopes in the prior art.

[0006] To achieve the above objectives, according to one aspect of the present invention, an arthroscope is provided. The arthroscope includes a first housing, an operating structure, a connecting structure, an insertion tube, and an endoscope tube. The operating structure is movably disposed on the first housing. At least a portion of the connecting structure is disposed inside the first housing. The operating structure and the connecting structure are drivenly connected. One end of the insertion tube is connected to the connecting structure, and the other end is disposed outside the first housing for puncture. A first end of the endoscope tube is fixed to the first housing, and a second end of the endoscope tube is disposed inside the insertion tube. The insertion tube is axially movable relative to the endoscope tube.

[0007] Furthermore, the insertion tube and the endoscope tube are coaxially arranged; and / or the first end of the endoscope tube is located outside the insertion tube and inside the first housing.

[0008] Furthermore, the connecting structure includes a first tube and a second tube. The first tube is disposed inside the first housing and is arranged along the axial direction of the mirror tube. One end of the first tube is connected to the insertion tube. The mirror tube passes through the first tube. The second end of the first tube is slidably engaged with the mirror tube. The second tube is disposed in the first tube and communicates with the first tube. The end of the second tube away from the first tube is driven and engaged with the operating structure.

[0009] Furthermore, a gap is formed between the insertion tube and the outer peripheral wall of the endoscope tube, the first tube body communicates with the gap, and the end of the second tube body away from the first tube body is open and exposed outside the first shell. The gap, the first tube body and the second tube body cooperate to form a channel structure.

[0010] Furthermore, the operating structure includes a sliding key, which is slidably disposed on the first housing along the axial direction of the mirror tube. The sliding key has a mounting hole, and at least a portion of the second tube is disposed inside the mounting hole. The sliding key drives the connecting structure to move.

[0011] Furthermore, the arthroscope also includes a sealing cap and a sealing element. The sealing cap is disposed between the second end of the endoscope tube and the first tube, and the outer peripheral surface of the sealing cap slides in fit with the inner wall surface of the first tube. The sealing element is disposed between the inner peripheral surface of the sealing cap and the outer peripheral surface of the endoscope tube.

[0012] Furthermore, the sealing element includes a spacer and a sealing ring. The spacer is fitted onto the mirror tube, and the outer circumferential surface of the spacer is connected to the inner circumferential surface of the sealing cap. The sealing ring is fitted onto the mirror tube, and sealing rings are provided at both ends of the spacer along the axial direction of the mirror tube. The inner circumferential surface of the sealing cap is connected to the sealing ring.

[0013] Furthermore, the arthroscope also includes a fixation block and a limiting block. The fixation block is disposed in the first housing, and the limiting plate is disposed in the fixation block. The limiting plate and the fixation block form an installation channel, and the second end of the arthroscope tube is fixed to the installation channel.

[0014] Furthermore, the arthroscope also includes an image sensor, an endoscope body, a first circuit board, and a light source. The image sensor and the endoscope body are disposed inside the endoscope body tube. The first circuit board is disposed inside the first housing and is signal-connected to the image sensor. The light source is disposed inside the first housing. The light-emitting end of the light source and the opening at the second end of the endoscope body tube are spaced apart from and opposite to each other along the axial direction of the endoscope body tube. The first circuit board is signal-connected to the light source.

[0015] Furthermore, the arthroscope also includes an independently mounted assembly, which includes a second housing, a power supply, and a second circuit board. Along the axial direction of the arthroscope tube, the second housing is detachably mounted on one side of the first housing. An operating part is provided on the second housing. The power supply is located inside the second housing, and the second circuit board is located inside the second housing. The second circuit board is plugged into the first circuit board, and the power supply is electrically connected to the second circuit board. The operating part is used to turn the second circuit board on or off.

[0016] Furthermore, the operating part is a button, and the mounting assembly also includes a connector, which is located between the button and the second circuit board. Pressing the button can connect to the second circuit board through the connector.

[0017] Furthermore, the mounting assembly also includes a mounting base, a display screen, and a lens.

[0019] Applying the technical solution of this invention, the arthroscope of this application employs an operating structure and a connecting structure for driving connection. Driven by the operating structure, the connecting structure causes the insertion tube to move axially relative to the endoscope tube. The endoscope tube is formed as a fixed structural component, thus eliminating the need for movement of the connecting cable adapted to the endoscope tube, avoiding fatigue damage and improving signal transmission stability. The insertion tube of this application is used for puncture, and its adjustable position simplifies operation, reduces the number of instrument changes, and consequently lowers surgical complexity and patient trauma risk. This solves the problem in the prior art where the use of arthroscopes is affected by cables, impacting effectiveness and lifespan. Attached Figure Description

[0036] To address the issue of poor performance of arthroscopy in existing technologies due to the interference of cables, this embodiment provides an arthroscopy.

[0037] like Figures 1 to 10 As shown, the arthroscope includes a first housing 10, an operating structure 20, a connecting structure 30, an insertion tube 40, and an endoscope tube 50. The operating structure 20 is movably disposed on the first housing 10 and is drivenly connected to the connecting structure 30. The operating structure 20 can be used to drive the connecting structure 30 to move.

[0038] Specifically, at least a portion of the connecting structure 30 is disposed inside the first housing 10 and connected to one end of the insertion tube 40 to achieve driving cooperation between the insertion tube 40 and the connecting structure 30. The operating structure 20 can drive the insertion tube 40 to move axially through the connecting structure 30, thereby obtaining a wider and more flexible surgical field. The other end of the insertion tube 40 is disposed outside the first housing 10 for puncturing the skin. The first end of the endoscope tube 50 is fixed to the first housing 10, and the second end of the endoscope tube 50 is disposed inside the insertion tube 40. The insertion tube 40 can move axially relative to the endoscope tube 50.

[0039] The insertion tube 40 is located at one end of the first housing 10 and is pointed, which facilitates puncture of the skin and other parts, eliminating the need for puncture needle penetration and simplifying the surgical procedure.

[0040] In this embodiment, the first end of the mirror tube 50 is disposed outside the insertion tube 40 and inside the first housing 10. The first end of the mirror tube 50 is disposed inside the first housing 10 to accommodate the light source 1010 and the first circuit board 100 inside the first housing 10; the first end of the mirror tube 50 is disposed outside the insertion tube 40 to facilitate assembly of the mirror tube 50 and to reduce the axial length of the insertion tube 40, thereby reducing costs.

[0041] In this embodiment, the insertion tube 40 and the endoscope tube 50 are coaxially arranged. The diameter of the endoscope tube 50 is smaller than that of the insertion tube 40, and a portion of the endoscope tube 50 is disposed inside the insertion tube 40. This coaxial arrangement of the insertion tube 40 and the endoscope tube 50 creates a uniform annular gap between them, ensuring that the insertion tube 40 is not interfered with by the endoscope tube 50 during axial extension and retraction, thus guaranteeing the stability of the insertion tube 40's movement. The coaxial arrangement of the endoscope tube 50 and the insertion tube 40, with the first end of the endoscope tube 50 located outside the insertion tube 40, achieves a reasonable assembly between the endoscope tube 50 and the insertion tube 40, ensuring the stability of the insertion tube 40 and the endoscope tube 50 in use, and also improving the ease of arthroscopy operation.

[0042] The arthroscope of this application employs an operating structure 20 and a connecting structure 30 for driving connection. Driven by the operating structure 20, the connecting structure 30 causes the insertion tube 40 to move axially relative to the arthroscope body tube 50. The arthroscope body tube 50 is a fixed structural component, thus eliminating the need for movement of the connecting cable adapted to it, preventing fatigue damage and improving signal transmission stability. The insertion tube 40 of this application is used for puncture, and its adjustable position simplifies operation, reduces the frequency of instrument changes, and consequently lowers surgical complexity and patient trauma risk. This solves the problem in existing technologies where the use of arthroscopes is affected by cables, impacting effectiveness and lifespan.

[0043] In this embodiment, the first housing 10 includes a detachably connected upper housing 110 and a lower housing 120, which cooperate to form the inner cavity of the first housing 10. The detachably connected upper housing 110 and lower housing 120 facilitate the installation and removal of the internal structural components of the first housing 10.

[0044] Specifically, the first upper housing 110 and the first lower housing 120 are detachably connected by fasteners such as bolts. The first upper housing 110 and the first lower housing 120 are provided with aligning threaded holes, and the fasteners engage with these threaded holes to lock the first upper housing 110 and the first lower housing 120 in place. This fastener structure strengthens the connection between the first upper housing 110 and the first lower housing 120 and facilitates their assembly and disassembly.

[0045] Specifically, the first upper housing 110 and the first lower housing 120 are connected by a slot and a snap-fit ​​mechanism. One of the upper housing 110 and the first lower housing 120 has a slot, and the other has a snap-fit ​​mechanism that engages with the slot. This slot and snap-fit ​​structure allows for the assembly and disassembly of the first upper housing 110 and the first lower housing 120 without adding any structural components, thus simplifying the operation and improving efficiency.

[0046] like Figure 3 and Figure 4 As shown, the connection structure 30 includes a first tube 310 and a second tube 320. The first tube 310 is disposed inside the first housing 10 and is arranged along the axial direction of the mirror tube 50. One end of the first tube 310 is connected to the insertion tube 40. The mirror tube 50 passes through the first tube 310. The second end of the first tube 310 is slidably engaged with the mirror tube 50. The second tube 320 is disposed in the first tube 310 and communicates with the first tube 310. The end of the second tube 320 away from the first tube 310 is driven to engage with the operation structure 20.

[0047] The first tube 310 and the second tube 320 are connected and cooperate to form a three-way pipe structure. For example, the first tube 310 and the second tube 320 are cooperated to form a Luer three-way pipe.

[0048] Specifically, one end of the first tube 310 is connected to the insertion tube 40. The operating structure 20 drives the second tube 320 to move, and the second tube 320 drives the insertion tube 40 to move through the first tube 310. The sliding fit between the first tube 310 and the mirror tube 50 ensures that the first tube 310 is not disturbed by the mirror tube 50 when it moves, thereby ensuring the movement of the insertion tube 40. At the same time, the structure of the mirror tube 50 passing through the first tube 310 and slidingly fitting with the first tube 310 also has the function of guiding and limiting the first tube 310, thereby indirectly increasing the stability and accuracy of the movement of the insertion tube 40.

[0049] In this embodiment, the end of the first tube 310 connected to the insertion tube 40 communicates with the gap formed between the insertion tube 40 and the outer peripheral wall of the endoscope tube 50. The end of the second tube 320 away from the first tube 310 is open and exposed outside the first housing 10. The gap, the first tube 310, and the second tube 320 cooperate to form a channel structure. When it is necessary to flush the joint or drain the fluid from the joint, the channel structure provides a path for fluid flow. The opening of the second tube 320, exposed outside the first housing 10, can be used to connect a fluid supply device or a suction device. This application improves the stability of fluid supply and suction paths by utilizing the channel structure formed between the endoscope tube 50, the insertion tube 40, the first tube 310, and the second tube 320, thereby improving the versatility of arthroscopy, the stability of operation, and the efficiency of arthroscopy use.

[0050] like Figures 1 to 5 As shown, the operating structure 20 is provided with a mounting hole 210 so that the opening of the second tube 320 can be exposed.

[0051] Specifically, the operating structure 20 includes a sliding key, which is slidably disposed on the first housing 10 along the axial direction of the mirror tube 50. The sliding key has a mounting hole 210, and at least a portion of the second tube 320 is disposed inside the mounting hole 210. The sliding key drives the connecting structure 30 to move.

[0052] The second tube 320 and the mounting hole 210 are formed in a shape-fitting structure to avoid the formation of a gap between the second tube 320 and the mounting hole 210, which would allow dust or liquid to enter the interior of the first housing 10, thus achieving airtightness and watertightness.

[0053] In this embodiment, a portion of the second tube 320 is disposed inside the mounting hole 210. When the sliding key slides, the second tube 320 can be pushed to move synchronously through the inner wall of the mounting hole 210. The second tube 320 drives the first tube 310, and the first tube 310 drives the insertion tube 40 to move synchronously, thereby realizing the sliding key operation to extend and retract the insertion tube 40.

[0054] like Figure 3 and Figure 4 As shown, the arthroscope also includes a sealing cap 60 and a sealing element 70. The sealing cap 60 is disposed between the endoscope tube 50 and the second end of the first tube 310. The outer peripheral surface of the sealing cap 60 is in sliding fit with the inner wall surface of the first tube 310. The sealing element 70 is disposed between the inner peripheral surface of the sealing cap 60 and the outer peripheral surface of the endoscope tube 50.

[0055] Specifically, in order to prevent the liquid inside the channel structure from leaking into the interior of the first housing 10, a sealing cap 60 and a sealing element 70 are provided between the first tube 310 and the mirror tube 50 to ensure that the first tube 310 and the mirror tube 50 can maintain a relative seal when sliding between them.

[0056] The sealing cap 60 is an annular structure, located at the end opening of the second end of the second tube 320, and is used to block the annular space formed between the mirror tube 50 and the first tube 310. The sealing element 70 is disposed on the sealing cap 60 and moves with the sealing cap 60. The sealing cap 60 can be integrally formed into the first tube 310, thereby ensuring the airtightness of the structure.

[0057] In this embodiment, the sealing element 70 includes a spacer and a sealing ring. The spacer is fitted onto the mirror tube 50, and its outer circumferential surface is connected to the inner circumferential surface of the sealing cap 60. The sealing ring is fitted onto the mirror tube 50, and sealing rings are provided at both ends of the spacer along the axial direction of the mirror tube 50. The inner circumferential surface of the sealing cap 60 is connected to the sealing rings. This structure of sealing rings and spacer achieves a sealing fit between the sealing cap 60 and the mirror tube 50, further ensuring the sealing performance of the first tube 310. Specifically, the structure of sealing rings on both sides of the spacer achieves multi-layer sealing, thereby ensuring that no liquid leakage occurs.

[0058] like Figures 3 to 5 As shown, the arthroscope also includes a fixing block 80 and a limiting block. The fixing block 80 is disposed in the first housing 10, and the limiting plate 90 is disposed in the fixing block 80. The limiting plate 90 and the fixing block 80 form an installation channel, and the second end of the arthroscope tube 50 is fixed to the installation channel.

[0059] The fixing block 80 is fixed to the inside of the first housing 10 by bolts and other connecting parts to achieve a detachable connection of the fixing block 80; the limiting plate 90 is set on the fixing block 80 by bolts and other connecting parts to achieve a detachable connection of the limiting plate 90; the combination of the fixing block 80 and the limiting plate 90 not only stably supports the endoscope tube 50 and ensures its stable position during the operation, but also achieves effective limiting and positioning of the endoscope tube 50 through the design of the installation channel, avoiding displacement or damage of the endoscope tube 50 due to improper operation.

[0060] Specifically, the limiting plate 90 and the fixing block 80 form an installation channel. This can be achieved by: a first groove structure extending axially along the lens tube 50 on the limiting plate 90, with the groove opening facing the fixing block 80; the fixing block 80 and the limiting plate 90 cooperating to form an installation channel for installing and locking the lens tube 50; or a second groove structure extending axially along the lens tube 50 on the fixing block 80, with the groove opening facing the limiting plate 90; the fixing block 80 and the limiting plate 90 cooperating to form an installation channel for installing and locking the lens tube 50; or a first groove structure extending axially along the lens tube 50 on the limiting plate 90, and a second groove structure extending axially along the lens tube 50 on the fixing block 80; the groove openings of the first and second groove structures communicating with each other to form an installation channel for installing and locking the lens tube 50.

[0061] In this embodiment, the arthroscopy tube 50 is fixed inside the first housing 10 by the fixing block 80 and the limiting plate 90. During use, the arthroscopy tube 50 does not move. Therefore, the wiring and structural components inside the first housing 10 that mate with the arthroscopy tube 50 do not need to move, thus avoiding potential pulling and wear on the wiring during arthroscopy movement and extending the service life of the arthroscopy. Specifically, the fixing block 80 is fixedly installed on the first lower housing 120.

[0062] like Figures 3 to 5 As shown, the arthroscope also includes an image sensor, an endoscope body, a first circuit board 100, and a light source 1010. The image sensor and the endoscope body are disposed inside the endoscope body tube 50. The first circuit board 100 is disposed inside the first housing 10 and is signal-connected to the image sensor. The light source 1010 is disposed inside the first housing 10. The light-emitting end of the light source 1010 and the opening at the second end of the endoscope body tube 50 are spaced apart from and opposite to each other along the axial direction of the endoscope body tube 50. The first circuit board 100 is signal-connected to the light source 1010.

[0063] Among them, the arthroscope integrates an image sensor and a scope, which can directly acquire and digitize images inside the joint, thus improving image quality.

[0064] Specifically, the first circuit board 100, a wireless PCB, is located on the first upper housing 110 of the insertion pin, establishing a signal connection with the image sensor and responsible for processing and transmitting image data. The light source 1010 is located in the first lower housing 120, with its light-emitting end axially spaced from the second end opening of the endoscope tube 50. It is connected to the control circuit of the light source 1010 via the first circuit board 100, ensuring the stability and controllability of the light source 1010 while avoiding the operational inconveniences of wired connections. The use of the light source 1010, in conjunction with the image sensor, enables the arthroscope to provide clear illumination and image acquisition inside the joint. The adoption of wireless transmission technology further enhances the flexibility and ease of operation of the arthroscope, reduces cable interference during surgery, and improves the performance of the arthroscope.

[0065] In this embodiment, the light source 1010 is mounted on the first lower housing 120 via the light source fixing plate 1011; the first circuit board 100 is mounted on the first upper housing 110. This application uses the first upper housing 110 and the first lower housing 120 to fix the light source 1010 and the first circuit board 100 respectively, which makes reasonable use of the space inside the first housing 10 and improves the space utilization rate of the internal cavity of the first housing 10.

[0066] like Figures 6 to 10 As shown, the arthroscope also includes an independently configured mounting assembly, which includes a second housing 1020, a power supply 1030, and a second circuit board 1050. Along the axial direction of the arthroscope tube 50, the second housing 1020 is detachably mounted on one side of the first housing 10. An operating part 1040 is provided on the second housing 1020. The power supply 1030 is located inside the second housing 1020, and the second circuit board 1050 is located inside the second housing 1020. The second circuit board 1050 is plugged into the first circuit board 100. The power supply 1030 is electrically connected to the second circuit board 1050 for power supply. The operating part 1040 is used to connect or disconnect the second circuit board 1050.

[0067] Specifically, the mounting components are formed as independent structures, realizing the modular design of the arthroscope. The second circuit board 1050 is a wireless control PCB board. The first circuit board 100 is provided with a plug-in interface 1001. The second circuit board 1050 and the first circuit board 100 are plugged in to form a signal connection. The second circuit board 1050 can wirelessly transmit signals with the host of the terminal device.

[0068] Meanwhile, the first housing 10 and the second housing 1020 are detachably connected, which can be by fasteners such as bolts or by snap-fit.

[0069] In this embodiment, the second housing 1020 includes a second upper housing 1021 and a second lower housing 1022, which cooperate to form the inner cavity of the second housing 1020. The detachable connection of the second upper housing 1021 and the second lower housing 1022 facilitates the installation and removal of the internal structural components of the second housing 1020.

[0070] Specifically, the second upper housing 1021 and the second lower housing 1022 are detachably connected by fasteners such as bolts. The second upper housing 1021 and the second lower housing 1022 are provided with aligning threaded holes, and the fasteners engage with these threaded holes to lock the second upper housing 1021 and the second lower housing 1022. This fastener structure strengthens the connection between the second upper housing 1021 and the second lower housing 1022 and facilitates their assembly and disassembly.

[0071] Specifically, the second upper housing 1021 and the second lower housing 1022 are connected by a slot and a snap-fit ​​mechanism. One of the upper housing 1021 and the lower housing 1022 has a slot, and the other has a snap-fit ​​mechanism that engages with the slot. This slot and snap-fit ​​structure allows for the assembly and disassembly of the second upper housing 1021 and the second lower housing 1022 without adding any structural components, thus simplifying the operation and improving efficiency.

[0072] like Figure 7 and Figure 8 As shown, the mounting assembly also includes a power cover. The second lower housing 1022 of the second housing 1020 has a power slot. The power supply 1030 is disposed inside the power slot. The power cover is disposed at the slot opening to cover the slot opening. The power supply 1030 is electrically connected to the second circuit board 1050 through positive electrode plates. Specifically, the power supply 1030 can be electrically connected to the second circuit board 1050 by contacting the positive and negative electrode plates soldered on the second circuit board 1050. The second circuit board 1050 is mounted on the second upper housing 1021. The operation unit 1040 is disposed on the second upper housing 1021.

[0073] Specifically, the operation unit 1040 is a button, and the mounting assembly also includes a connector 1090, which is disposed between the button and the second circuit board 1050. Pressing the button can connect to the second circuit board 1050 through the connector 1090.

[0079] During use, the insertion tube 40 directly punctures the skin and enters the joint through its tip, simplifying the pre-operative incision procedure. Subsequently, by pushing and pulling the operating structure 20, its sliding along the axial direction of the endoscope tube 50 is controlled, thereby driving the connected structure 30 to achieve the telescopic movement of the insertion tube 40 relative to the endoscope tube 50. This precisely adjusts the position of the endoscope within the joint, avoiding fatigue damage and signal instability that may be caused by traditional cable connections. After adjustment, the light source 1010 and image sensor begin the image acquisition and transmission process. The image sensor at the front end of the endoscope tube 50 converts the captured light signal into an electrical signal, which is transmitted via the first circuit board 100 to the second circuit board 1050 for processing, and finally displays a high-definition image of the joint interior on the display screen 1070.

[0080] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0081] The arthroscope of this application employs an operating structure 20 and a connecting structure 30 for driving connection. Driven by the operating structure 20, the connecting structure 30 causes the insertion tube 40 to move axially relative to the arthroscope body tube 50. The arthroscope body tube 50 is a fixed structural component, thus eliminating the need for movement of the connecting cable adapted to it, preventing fatigue damage and improving signal transmission stability. The insertion tube 40 of this application is used for puncture, and its adjustable position simplifies operation, reduces the frequency of instrument changes, and consequently lowers surgical complexity and patient trauma risk. This solves the problem in existing technologies where the use of arthroscopes is affected by cables, impacting effectiveness and lifespan.

[0082] The arthroscope of this application adopts a modular structure, which can be assembled when in use and disassembled when not in use, thereby improving the flexibility and operability of the structure and thus improving the user experience. In addition, the modular structure reduces the use of internal cables, thereby avoiding problems such as cable wear affecting the use of the arthroscope.
