Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a portable orthopedic arthroscopy device. Background Technology

[0002] Arthroscopic surgery has become an important method for treating intra-articular diseases of the knee, shoulder, and ankle joints due to its advantages such as minimal trauma, rapid recovery, and accurate diagnosis. Traditional arthroscopy typically consists of a camera unit, cold light source, monitor, infusion pump, and various cables. The entire system is large and heavy, often requiring a special trolley or a fixed operating room, making it difficult to conduct immediate examinations in outpatient clinics, primary healthcare institutions, or field rescue scenarios.

[0003] In recent years, with the popularization of minimally invasive concepts and the development of electronic technology, miniaturized, integrated portable arthroscopic devices have gradually emerged. These devices integrate the light source, camera, and display screen into one unit, simplifying the equipment structure and reducing space occupation. However, existing portable arthroscopic devices still have some shortcomings: for example, the optical surface at the front end of the endoscope comes into direct contact with synovial fluid, blood, and tissue debris during surgery, requiring postoperative cleaning and high-temperature, high-pressure sterilization. Existing devices lack automatic cleaning mechanisms, and residual contaminants easily dry and harden, affecting subsequent cleaning. Furthermore, the functions of existing portable arthroscopic devices are independent, and the operation steps are scattered. Users need to perform multiple actions when installing or removing the endoscope, making the operation cumbersome and reducing clinical efficiency.

[0004] Therefore, this invention proposes a portable orthopedic arthroscopy device to simplify the operation process and improve portability, which has important clinical significance and practical value. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a portable orthopedic arthroscopy device that simplifies the operation process, reduces operation time, and improves the overall convenience and smoothness of the device's operation.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: a portable orthopedic arthroscopy device includes a handle, an endoscope body detachably connected to the handle, a clamping assembly for fixing or releasing the endoscope body between the handle and the endoscope body, and a cleaning assembly for cleaning the optical surface at the front end of the endoscope body is provided inside the handle.

[0007] The handle is also equipped with a transmission component that drives the clamping component and the cleaning component to operate in conjunction. When the transmission component moves forward, it drives the clamping component to fix the lens body. When the transmission component moves in reverse, it drives the clamping component to release the lens body and simultaneously drives the cleaning component to clean the lens body.

[0008] The technical principles of the above solution are as follows:

[0009] The mechanical linkage between clamping and cleaning is achieved through the forward and reverse movements of the transmission component. During forward movement, the transmission component drives the clamping component to close, locking the microscope body to the front end of the handle. During reverse movement, the transmission component first drives the clamping component to open and release the microscope body, then drives the cleaning component to pump cleaning fluid to the optical surface at the front end of the microscope body, completing the spray cleaning. The entire process achieves dual functions through mechanical linkage: forward installation and locking, and reverse disassembly and cleaning, ensuring the cleanliness of the optical surface, facilitating high-temperature sterilization, and improving operational efficiency and aseptic safety.

[0010] The above approach has the following beneficial effects:

[0011] 1. This solution achieves mechanical linkage between clamping and cleaning through the forward and reverse movement of the transmission components. Forward movement can quickly lock the scope, while reverse movement can simultaneously release the scope and clean the optical surface. Operators do not need to repeatedly switch between different functions, simplifying the operation process, reducing operation time, and making it suitable for emergency or complex surgical scenarios, thus improving the overall convenience and smoothness of the device operation.

[0012] 2. In the reverse motion, the transmission component drives the cleaning component to deliver the cleaning fluid to the optical surface for spray cleaning, which can effectively remove contaminants and prevent contaminants from drying and solidifying, making subsequent cleaning effective. At the same time, the cleaned device is easy to perform aseptic treatment such as high-temperature sterilization, further improving aseptic safety and providing a strong guarantee for the success of the operation.

[0013] 3. This solution integrates clamping and cleaning functions into the linkage mechanism of the transmission components, simplifying the device structure, reducing manufacturing costs, and facilitating maintenance or component replacement through detachable connections. The device's convenient operation reduces the risk of damage due to improper operation, extends its service life, and allows for rapid lens installation and cleaning, thus improving its efficiency.

[0014] Furthermore, the clamping assembly includes a housing fixedly connected to the outer wall of the handle, a base fixedly connected to the inner wall of the housing, a number of grippers circumferentially hinged to the base, and a number of slots corresponding to the grippers on the lens body; a ratchet is rotatably fitted to the inner wall of the base, and a number of slide rods are circumferentially slidably fitted to the outer wall of the ratchet, with the end of the slide rod away from the ratchet abutting against the adjacent gripper; a torsion spring is also sleeved on the hinge axis between the gripper and the base; and a transmission assembly is used to drive the ratchet to rotate.

[0015] Beneficial effects: The transmission component drives the ratchet to rotate, which in turn causes the gripper to rotate around the hinge axis via the slide bar. In conjunction with the torsion spring, the ratchet opens and closes, allowing it to accurately engage with the endoscope slot for fixation and release. The structure is compact and stable, and the operation is convenient, providing a reliable guarantee for the fixation of the endoscope in portable orthopedic arthroscopy devices.

[0016] Furthermore, the transmission assembly includes a drive wheel that is rotatably fitted to the top of the handle, the drive wheel extending to the outside of the handle, a drive shaft fixedly connected to the side of the ratchet away from the mirror body, and a driven wheel fixedly connected to the end of the drive shaft away from the ratchet on the same axis, the driven wheel meshing with the drive wheel; the handle also has a locking assembly for locking the driven wheel.

[0017] Beneficial effects: By rotating the driving wheel, the meshing driven wheel drives the transmission shaft and ratchet to rotate, realizing the clamping component's action, making operation simple and labor-saving. The locking component can fix the driven wheel, preventing accidental rotation, ensuring the scope body is firmly fixed, and improving the safety and reliability of the device.

[0018] Furthermore, the locking assembly includes a telescopic component fixedly connected to the inner wall of the handle, and the telescopic component is signal-connected to a controller; the output shaft of the telescopic component is fixedly connected to a brake block, and the brake block abuts against the outer wall of the driven wheel.

[0019] Beneficial effects: The telescopic component is controlled by the controller, allowing the brake block to quickly abut or separate from the outer wall of the driven wheel. This effectively locks the driven wheel when the arthroscopy body is fixed, preventing accidental rotation, ensuring stable operation of the clamping assembly, and improving the safety and reliability of the portable arthroscopy device.

[0020] Furthermore, the cleaning component includes a piston cavity embedded in the inner wall of the handle, with a piston plate slidably fitted on the inner wall of the piston cavity; an input pipe and an output pipe are connected to the piston cavity, and a one-way valve is provided on the communication path between the input pipe and the output pipe and the piston cavity.

[0021] The mirror body has a liquid outlet channel inside its side wall, which connects to the end of the mirror body away from the base. The base has a liquid inlet channel that connects to the liquid outlet channel. The end of the input pipe away from the piston cavity is connected to a storage cavity for storing cleaning fluid, and the end of the output pipe away from the piston cavity is connected to the liquid inlet channel. The transmission assembly is used to drive the piston plate to move.

[0022] Beneficial effects: The transmission assembly drives the piston plate to move, and with the help of the one-way valve, the cleaning fluid enters the piston chamber from the storage chamber through the input pipe, and is then sprayed to the front end of the microscope body through the output pipe, the inlet channel and the outlet channel. This can complete the cleaning after the inspection operation, ensure the cleanliness of the optical surface and improve the accuracy of the inspection.

[0023] Furthermore, the transmission assembly also includes a lead screw that is coaxially and fixedly connected to the drive wheel. The lead screw passes through the piston cavity and is threadedly fitted with a nut seat. The nut seat is fixedly connected to the piston plate. A locking block is symmetrically fixedly connected to the piston plate, and a sliding groove is opened on the side wall of the piston cavity for the locking block to slide.

[0024] Beneficial effects: The drive wheel rotates the lead screw, which in turn converts the rotational motion into linear movement of the piston plate via the nut seat, thus achieving the delivery of cleaning fluid. The locking block and slide groove work together to ensure smooth sliding of the piston plate, preventing deviation and improving the stability and reliability of the cleaning assembly.

[0025] Furthermore, a sealing layer is fixedly connected to the inner wall of the housing, and a transmission pipe is connected to the side of the piston cavity away from the input pipe. The end of the transmission pipe away from the piston cavity is connected to the inside of the sealing layer.

[0026] Beneficial effects: The design of the sealing layer on the inner wall of the shell, which is connected to the transfer tube, allows the medium from the other side of the piston cavity to enter the sealing layer area through the transfer tube when the scope is installed in place. This fills the gap between the scope and the handle, forming a reliable seal that prevents external contaminants from entering and ensures a sterile environment during the examination.

[0027] Furthermore, a converging lens is slidably fitted onto the inner wall of the endoscope, and a magnetic block is fixedly connected to the outer wall of the converging lens; several electromagnets are embedded and installed inside the side wall of the endoscope, and all electromagnets are connected to the controller signal and magnetically engaged with the magnetic block.

[0028] Beneficial effects: By controlling the magnetism of the electromagnet through the controller, it can generate attraction or repulsion between the electromagnet and the magnetic block on the condenser, thus controlling the sliding of the condenser on the inner wall of the endoscope; the position of the condenser can be adjusted according to the actual examination needs, optimizing the imaging focusing effect, providing doctors with clearer and more accurate images of the inside of the joint, and improving diagnostic accuracy.

[0029] Furthermore, a buffer cavity is provided on the side wall of the end of the microscope body away from the base. The buffer cavity is connected to the liquid outlet channel, and an elastic valve is provided on the communication path between the liquid outlet channel and the buffer cavity. A rotating shaft is rotatably fitted on the inner wall of the buffer cavity, and a spiral blade is fixedly connected to the rotating shaft. A scraper is also rotatably fitted on the end of the microscope body away from the base, and the rotating shaft and the scraper are fixedly connected.

[0030] Beneficial effects: The cleaning solution flows through the outlet channel to the buffer chamber, where a flexible valve buffers the pressure and opens when the pressure reaches the set value. The spiral blades rotate around the shaft with the liquid flow, driving the scraper to remove impurities from the tip of the microscope. Together, these components ensure a stable output of cleaning solution, improve the cleaning effect of the microscope, and guarantee a clear field of view during inspection.

[0031] Furthermore, an image sensor is fixedly connected to the inner wall of the handle, and a display can also be detachably connected to the handle. Both the display and the image sensor are connected to the controller signal.

[0032] Beneficial effects: The image sensor, fixed to the inner wall of the handle, captures images of the joint interior and transmits them to the controller, while the monitor allows doctors to view them at any time. This design makes the examination process more intuitive, allowing doctors to adjust their procedures promptly based on the images, thus improving examination efficiency and diagnostic accuracy.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0044] The following detailed description illustrates the specific implementation method:

[0045] Example 1:

[0046] As attached Figures 1-7 As shown: A portable orthopedic arthroscopy device includes a handle 1, a scope 2 detachably connected to the handle 1, a clamping assembly for fixing or releasing the scope 2 between the handle 1 and the scope 2; and a cleaning assembly for cleaning the optical surface of the front end of the scope 2 is provided inside the handle 1.

[0047] The handle 1 is also equipped with a transmission component that drives the clamping component and the cleaning component to operate in conjunction; combined with Figure 3 As shown, the clamping assembly includes a housing 3 that is screwed to the outer wall of the handle 1. A base 4 is screwed to the inner wall of the housing 3. Several grippers 5 are circumferentially hinged to the base 4. Several slots corresponding to the grippers 5 are opened on the lens body 2. A ratchet 6 is rotatably fitted to the inner wall of the base 4. Several slide rods 7 are circumferentially slidably fitted to the outer wall of the ratchet 6. The end of the slide rod 7 away from the ratchet 6 abuts against the adjacent gripper 5. A torsion spring is also sleeved on the hinge axis between the gripper 5 and the base 4.

[0048] The transmission assembly includes a drive wheel 8 rotatably fitted to the top of the handle 1, extending outside the handle 1. A drive shaft is keyed to the side of the ratchet 6 away from the mirror body 2, and a driven wheel 9 is coaxially keyed to the end of the drive shaft away from the ratchet 6. The driven wheel 9 meshes with the drive wheel 8. The handle 1 also has a locking assembly for locking the driven wheel 9. The transmission assembly drives the ratchet 6 to rotate. When the transmission assembly moves forward, it drives the clamping assembly to fix the mirror body 2. When the transmission assembly moves in reverse, it drives the clamping assembly to release the mirror body 2 and simultaneously drives the cleaning assembly to clean the mirror body 2.

[0049] The locking assembly includes a telescopic member 10 that is screwed and fixed to the inner wall of the handle 1, and the telescopic member 10 is signal-connected to a controller; the output shaft of the telescopic member 10 is screwed and fixed to a brake block, which abuts against the outer wall of the driven wheel 9.

[0050] Specifically, when installing the scope body 2, first insert the scope body 2 into the front end of the handle 1, aligning the slot on the scope body 2 with the gripper 5. Then, the operator rotates the drive wheel 8, which drives the driven wheel 9, which meshes with it, to rotate. The driven wheel 9, through a keyed drive shaft, drives the ratchet 6 to rotate synchronously. For example... Figure 3 As shown, when the ratchet 6 rotates clockwise, the contour surface (arc-shaped protrusion) of the outer wall of the ratchet 6 pushes the circumferentially sliding rod 7 to move radially. The sliding rod 7 extends outward and pushes against the outer wall of the gripper 5, overcoming the torsion spring force on the hinge axis of the gripper 5, causing the gripper 5 to close inward around the hinge axis and engage in the corresponding slot of the mirror body 2, thus locking the mirror body 2. When the gripper 5 is locked (i.e., when the sliding rod 7 is extended to its maximum position), the controller controls the extension member 10 to extend, and the brake block on its output shaft abuts against the outer wall of the driven wheel 9 to prevent the driving wheel 8 and the ratchet 6 from reversing due to vibration or accidental contact, thereby maintaining the locked state.

[0051] When disassembling the endoscope 2, the controller first issues a command to retract the telescopic component 10, disengaging the brake block from the outer wall of the driven wheel 9 and releasing the rotation restriction on the driven wheel 9. Then, the operator rotates the driving wheel 8 in the opposite direction, which, through the driven wheel 9 and the drive shaft, drives the ratchet 6 to rotate in the opposite direction. When the ratchet 6 reverses direction, its outer wall contour surface (arc-shaped protrusion) releases the radial thrust on the slide bar 7, causing the slide bar 7 to return to its original position. The gripper 5, under the restoring force of the torsion spring, opens outward around the hinge axis, disengaging from the slot on the endoscope 2. After the gripper 5 opens, the endoscope 2 can be easily pulled out from the front end of the handle 1. In this embodiment, the quick-installation design helps improve clinical operation efficiency. This detachable design allows the device to flexibly select the required components according to usage needs, or to be disassembled for repair or replacement when the endoscope 2 or other components are damaged, improving the flexibility of the equipment.

[0052] Combination Figure 5As shown, the cleaning assembly includes a piston chamber 11 embedded in the inner wall of the handle 1, and a piston plate 12 slidably fitted onto the inner wall of the piston chamber 11. An input pipe and an output pipe are connected to the piston chamber 11, and one-way valves are provided on the communication paths between the input pipe, the output pipe, and the piston chamber 11. In this embodiment, the one-way valves are used to provide unidirectional flow of fluid, allowing fluid to flow in through the input pipe and then out through the output pipe.

[0053] A liquid outlet channel is formed inside the side wall of the mirror body 2, which connects to the end of the mirror body 2 away from the base 4. An inlet channel, connected to the liquid outlet channel, is formed on the base 4. The end of the inlet pipe away from the piston chamber 11 is connected to a storage chamber for storing cleaning fluid, and the end of the outlet pipe away from the piston chamber 11 is connected to the inlet channel. In this embodiment, the storage chamber is embedded within the handle 1, and a flow channel for filling the cleaning fluid is integrated into the storage chamber.

[0054] The transmission assembly also includes a lead screw 13 coaxially keyed to the drive wheel 8. The lead screw 13 passes through the piston cavity 11 and is threadedly fitted with a nut seat 14. The nut seat 14 is screwed and fixedly connected to the piston plate 12. The piston plate 12 has symmetrically integrally formed locking blocks, and the side wall of the piston cavity 11 has a sliding groove for the locking blocks to slide. In this embodiment, the locking blocks and the sliding groove can provide guidance for the nut seat 14, so that the nut seat 14 maintains a linear motion trajectory. The transmission assembly is used to drive the piston plate 12 to move.

[0055] Specifically, when the drive wheel 8 rotates, the lead screw 13, coaxially keyed to the drive wheel 8, rotates accordingly. The lead screw 13 passes through the piston cavity 11 and is threadedly engaged with the internal nut seat 14. The nut seat 14 is fixedly connected to the piston plate 12 by screws. Because the symmetrically integrally formed retaining blocks on the piston plate 12 are embedded in the sliding grooves on the side wall of the piston cavity 11, restricting the circumferential rotation of the nut seat 14, the rotational motion of the lead screw 13 can be converted into linear reciprocating motion of the nut seat 14 and the piston plate 12 along the inner wall of the piston cavity 11. The specific reciprocating motion is as follows:

[0056] When the drive wheel 8 rotates forward (i.e., in the direction of installing the mirror body 2 and locking the clamping assembly), the lead screw 13 drives the nut seat 14 and piston plate 12 to move away from the input pipe. At this time, the volume of the piston chamber 11 increases, generating negative pressure. The input pipe is connected to the storage chamber, and the one-way valve at the input pipe opens under the action of negative pressure, drawing the cleaning fluid in the storage chamber into the piston chamber 11; while the one-way valve at the output pipe closes due to negative pressure to prevent liquid backflow. When the drive wheel 8 rotates in the reverse direction (i.e., in the direction of disassembling the mirror body 2 and releasing the clamping assembly), the lead screw 13 drives the nut seat 14 and piston plate 12 to move in the reverse direction, reducing the volume of the piston chamber 11 and increasing the pressure. At this time, the one-way valve at the input pipe closes, and the one-way valve at the output pipe opens. The cleaning fluid is pumped out of the piston chamber 11 and flows sequentially through the output pipe, the liquid inlet channel opened on the base 4, and the liquid outlet channel in the side wall of the mirror body 2, finally flowing out from near the front optical surface of the mirror body 2 away from the base 4, providing immediate cleaning of the optical surface.

[0057] The entire process achieves linkage between the installation of the scope 2 and the pumping action: forward rotation completes the fixing of the scope 2 and liquid aspiration; reverse rotation triggers the spray cleaning while unlocking the scope 2. Since the lead screw 13 is coaxially connected to the drive wheel 8, the cleaning action and the clamping action share the same power source, requiring no additional operation or electronic control, further improving the practicality of the device.

[0058] Combination Figure 6 As shown, a sealing layer 15 is also adhered to the inner wall of the housing 3. A transmission pipe is connected to the side of the piston cavity 11 away from the input pipe, and the end of the transmission pipe away from the piston cavity 11 is connected to the interior of the sealing layer 15. In this embodiment, the sealing layer 15 is made of an elastic material, such as rubber.

[0059] Specifically, when the drive wheel 8 rotates in the forward direction (i.e., the mirror body 2 is installed and locked), the lead screw 13 drives the piston plate 12 to move away from the input pipe. At this time, a negative pressure is generated on one side of the piston chamber 11 to draw in liquid, while the other side compresses the medium on that side, inputting the medium into the transmission pipe. In this embodiment, the medium can be gas or liquid. The other end of the transmission pipe is connected to the sealing layer 15, which is bonded to the inner wall of the housing 3, and the medium is then filled into the sealing layer 15. The sealing layer 15 is made of elastic material, which gradually expands after the medium is filled, tightly wrapping the outer wall of the mirror body 2, thereby forming a reliable sealing barrier between the mirror body 2 and the housing 3, preventing external contaminants from penetrating into the interior of the housing 3, and producing an additional clamping effect to clamp the mirror body 2, thereby increasing the stability of the device.

[0060] When the drive wheel 8 rotates in the reverse direction (disassembling the mirror body 2), the piston plate 12 moves in the reverse direction, generating negative pressure. The medium in the sealing layer 15 is drawn back to the piston cavity 11 through the transmission pipe. The sealing layer 15 contracts and resets, releasing the mirror body 2 and facilitating its easy removal. This design achieves the effect of synchronous expansion sealing during forward locking and synchronous contraction unsealing during reverse unlocking, synchronizing the clamping and sealing actions without additional operation, further improving the overall sealing performance and ease of operation of the device.

[0061] Example 2:

[0062] As attached Figure 7 As shown, the difference from Embodiment 1 is that a converging lens 16 is slidably fitted on the inner wall of the mirror body 2, and a magnetic block 17 is bonded to the outer wall of the converging lens 16; several electromagnets 18 are embedded in the side wall of the mirror body 2, and all electromagnets 18 are connected to the controller signal and are magnetically engaged with the magnetic block 17.

[0063] The specific implementation process is as follows: Inside the mirror body 2, the condenser lens 16 can slide along the inner wall, and a magnet 17 is adhered to its outer wall. Several electromagnets 18 are embedded in the side wall of the mirror body 2. These electromagnets 18 are all connected to the controller signal and form a magnetic engagement with the magnet 17. When the controller outputs current of different directions and intensities to the electromagnets 18 according to the operation command, the electromagnets 18 generate corresponding magnetic fields, which generate attraction or repulsion with the magnet 17, thereby driving the condenser lens 16 to slide axially along the inner wall of the mirror body 2. By adjusting the energizing sequence and current magnitude of the electromagnets 18, the moving direction and displacement of the condenser lens 16 can be controlled, thereby changing the imaging focus or magnification.

[0064] This adjustment process can be linked with the movement of the transmission components (such as the controller simultaneously adjusting the electromagnet 18 to move the focusing lens 16 to the preset position while the drive wheel 8 rotates to lock the scope body 2), or it can be performed independently of the clamping and cleaning actions, thereby achieving intraoperative focusing adjustment, simplifying external operations, and improving the integration and portability of the device.

[0065] Example 3:

[0066] As attached Figure 7 As shown, the difference from Embodiment 2 is that the side wall of the end of the mirror body 2 away from the base 4 is also provided with a buffer cavity 19. The buffer cavity 19 is connected to the liquid outlet channel. An elastic valve is provided on the communication path between the liquid outlet channel and the buffer cavity 19. In this embodiment, when the transmission component runs in reverse, the cleaning fluid enters the elastic valve. After the pressure accumulates to the preset pressure, the elastic valve opens. The inner wall of the buffer cavity 19 is rotatably fitted with a rotating shaft. A spiral blade 20 is fixedly connected to the rotating shaft with screws. A scraper 21 is also rotatably fitted at the end of the mirror body 2 away from the base 4. The rotating shaft and the scraper 21 are fixedly connected with screws.

[0067] The specific implementation process is as follows: A buffer cavity 19 is provided in the front side wall of the endoscope 2 away from the base 4. This buffer cavity 19 is connected to the liquid outlet channel, and an elastic valve is provided on the connection path. When the transmission component rotates in the reverse direction to trigger cleaning, the cleaning fluid flows to the front end of the endoscope 2 through the output pipe, the inlet channel, and the outlet channel. Under pressure, it pushes open the elastic valve and enters the buffer cavity 19. The cleaning fluid impacts the spiral blade 20 in the buffer cavity 19, driving the rotating shaft to rotate. The rotating shaft then drives the scraper 21, which is fixed to it with screws, to rotate synchronously. The scraper 21 is in close contact with the optical surface at the front end of the endoscope 2 and continuously scrapes the optical surface during rotation. Combined with the rinsing of the cleaning fluid, it removes contaminants such as blood and tissue fluid adhering to the optical surface.

[0068] When the cleaning fluid supply stops, the flexible valve closes to prevent residual liquid from flowing back or dripping. This design converts the liquid pressure of the cleaning fluid into the rotational power of the scraper 21, eliminating the need for additional drive components. This achieves a coordinated cleaning process where the liquid flow drives the spiral blade 20 to rotate, which in turn drives the scraper 21 to rotate via the shaft, further enhancing the self-cleaning effect of the optical surface. During inspection, if the optical surface in front of the scope 2 becomes blurred due to blood or other contaminants, the reciprocating motion of the transmission components can be repeated, causing the scraper 21 to move back and forth. This, combined with the rinsing of the cleaning fluid, ensures that the front end of the scope 2 remains clean, further improving the device's practicality and reducing secondary damage caused by repeated punctures.

[0069] Example 4:

[0070] As attached Figure 4 As shown, the difference from Embodiment 3 is that an image sensor 22 is fixedly connected to the inner wall of the handle 1 by screws, and a display 23 can also be detachably connected to the handle 1. Both the display 23 and the image sensor 22 are connected to the controller signal.

[0071] The specific implementation process is as follows: During device operation, after the endoscope 2 is installed and locked and the clamping assembly is fixed, the controller sends a start command to the image sensor 22. The image sensor 22 acquires images of the joint cavity transmitted through the front optical surface of the endoscope 2 and the internal converging lens 16, and transmits the acquired image signals to the controller in real time. After processing the image signals (such as noise reduction, color correction, and gain adjustment), the controller sends the processed video signal to the display 23. The display 23 instantly displays clear images of the joint for the doctor to observe and diagnose. In addition, the detachable connection between the display 23 and the handle 1 allows the doctor to remove the display 23 as needed and place it in a more convenient observation position.

[0072] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
