[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0041] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0042] To address the problem that existing arthroscopy techniques suffer from complex and simple structures that affect operational flexibility and user experience, this embodiment provides an arthroscopy.

[0043] like Figures 1 to 16 As shown, the arthroscope includes a puncture assembly 10 and a controller assembly 20 and a lead assembly 30 that are alternatively connected to the puncture assembly 10. The controller assembly 20 and the lead assembly 30 are each formed as independent structural components that are detachably connected to the puncture assembly 10, thereby facilitating the replacement of the controller assembly 20 and the lead assembly 30.

[0044] The puncture assembly 10 includes a first housing 110, an operating structure 120, an insertion tube 130, a scope tube 140, and a first circuit board 150. The operating structure 120 is movably disposed on the first housing 110. The insertion tube 130 is disposed on the first housing 110, and the end of the insertion tube 130 away from the first housing 110 is used for puncturing the skin. The first end of the scope tube 140 is disposed inside the first housing 110 and connected to the operating structure 120. The second end of the scope tube 140 is disposed inside the insertion tube 130. The scope tube 140 can move axially relative to the insertion tube 130. The first circuit board 150 is disposed inside the first housing 110.

[0045] The controller assembly 20 has a second circuit board 220, which is connected to the first circuit board 150. Signal conduction is formed between the two circuit boards, and the second circuit board 220 is used for signal processing. The wire assembly 30 includes a data line 310, one end of which is connected to the first circuit board 150 and the other end is used to connect to a terminal device for signal processing. The terminal device can be a computer, tablet, mobile phone, or other devices.

[0046] Specifically, the first circuit board 150 has a plug-in interface 151, and the second circuit board 220 of the controller assembly 20 and the data line 310 of the wire assembly 30 can be plugged into the plug-in interface 151.

[0047] The arthroscope of this application provides a lead wire assembly 30 and a controller assembly 20 that are interchangeably connected to the puncture assembly 10, thus forming a modular three-part structure. The second circuit board 220 of the controller assembly 20 is directly connected to the first circuit board 150 without the need for a wire, forming a wireless connection. The lead wire assembly 30 connects the first circuit board 150 and the terminal device via a data cable 310, forming a wired connection. This application provides two different arthroscopes—one with wired connection and one with wireless connection—through the selective combination of the puncture assembly 10, the lead wire assembly 30, and the controller assembly 20, thus adapting to different operating scenarios and different user groups. The modular structure of the arthroscope improves operational flexibility and applicability. The interchangeable structure ensures the adaptability of the arthroscope in different environments, improving its efficiency.

[0048] In this embodiment, the insertion tube 130 and the endoscope tube 140 are coaxially arranged. The diameter of the endoscope tube 140 is smaller than that of the insertion tube 130. A portion of the endoscope tube 140 is disposed inside the insertion tube 130. By using the coaxial arrangement of the insertion tube 130 and the endoscope tube 140, a uniform annular gap can be formed between the endoscope tube 140 and the insertion tube 130. This ensures that the endoscope tube 140 will not affect the insertion tube 130 during axial extension and retraction, thereby ensuring the stability of the insertion tube 130 and avoiding secondary movement of the insertion tube 130 after it is inserted into the skin, which could cause stinging.

[0049] The arthroscopy tube 140 and the insertion tube 130 are coaxially arranged, with the first end of the arthroscopy tube 140 located outside the insertion tube 130. This achieves a reasonable assembly between the arthroscopy tube 140 and the insertion tube 130, ensuring the stability of the use of the insertion tube 130 and the arthroscopy tube 140, and also improving the convenience of arthroscopy operation.

[0050] In this embodiment, one end of the endoscope tube 140, which is located inside the first housing 110, is located outside the insertion tube 130. The end of the endoscope tube 140 is located inside the first housing 110 to accommodate the light source 190 and the first circuit board 150 inside the first housing 110; the other end is located outside the insertion tube 130 to facilitate cooperation with the operating structure 120, enabling axial telescopic movement of the endoscope tube 140 and facilitating the acquisition of a wider and more flexible surgical field.

[0051] The insertion tube 130 is located outside the first housing 110, and the end for puncture is formed into a pointed shape, which facilitates puncture of the skin, etc., eliminating the need for puncture needle piercing and simplifying the surgical procedure.

[0052] In this embodiment, the first housing 110 includes a detachably connected upper housing 111 and a lower housing 112, which cooperate to form the inner cavity of the first housing 110. The detachably connected upper housing 111 and lower housing 112 facilitate the installation and removal of the internal structural components of the first housing 110.

[0053] Specifically, the first upper housing 111 and the first lower housing 112 are detachably connected by fasteners such as bolts. The first upper housing 111 and the first lower housing 112 are provided with aligning threaded holes, and the fasteners engage with these threaded holes to lock the first upper housing 111 and the first lower housing 112 in place. This fastener structure strengthens the connection between the first upper housing 111 and the first lower housing 112 and facilitates their assembly and disassembly.

[0054] Specifically, the first upper housing 111 and the first lower housing 112 are connected by a slot and a snap-fit ​​mechanism. One of the upper housing 111 and the first lower housing 112 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 111 and the first lower housing 112 without adding any structural components, thus simplifying the operation and improving efficiency.

[0055] like Figures 1 to 7 As shown, the operation structure 120 includes an operation key 121 and a positioning block 122. The operation key 121 is slidably disposed on the first housing 110 along the axial direction of the microscope tube 140. The positioning block 122 is slidably disposed inside the first housing 110. At least a part of the operation key 121 is disposed inside the first housing 110 and drives and cooperates with the positioning block 122. The second end of the microscope tube 140 is fixedly connected to the positioning block 122. The operation key 121 drives the microscope tube 140 to move axially through the positioning block 122.

[0056] The second end of the microscope tube 140 is connected to the positioning block 122 to form a relatively fixed structure. By pushing the operating structure 120, the positioning block 122 is moved, and the positioning block 122 drives the microscope tube 140 to move axially. Thus, the operating structure 120 indirectly drives the microscope tube 140 to move through the positioning block 122.

[0057] Specifically, the positioning block 122 has a mounting groove arranged radially along the lens tube 140, and the first housing 110 has a sliding hole extending axially along the lens tube 140. A part of the operation key 121 is slidably disposed on the surface of the first housing 110, and the other part extends into the interior of the first housing 110 and into the mounting groove through the sliding hole. The structure of the sliding hole has the effect of guiding and limiting the operation key 121, so as to ensure that the operation key 121, the positioning block 122 and the lens tube 140 all move along the extension direction of the sliding hole.

[0058] The operation key 121 is inserted into the mounting slot to drive the positioning block 122. The part of the operation key 121 located inside the first housing 110 is inserted into the mounting slot, and this part is adapted to the shape of the mounting slot, thereby forming a relatively fixed structure between the positioning block 122 and the operation structure 120. When the operation key 121 is pushed, the positioning block 122 can be moved through the inner wall of the mounting slot.

[0059] This application, through the structural design of the positioning block 122, ensures that the arthroscopy tube 140 can move smoothly along the axial direction under the drive of the operating structure 120, thereby improving the efficiency of arthroscopy use.

[0060] In this embodiment, the inner wall surface of the first housing 110 has a groove 1111 along the axial direction of the mirror tube 140. The positioning block 122 is slidably disposed in the groove 1111. The groove 1111 has the effect of limiting and guiding the positioning block 122, thereby improving the stability and accuracy of the movement of the positioning block 122, and thus ensuring the movement path and movement distance of the mirror tube 140.

[0061] like Figures 1 to 6 As shown, the puncture assembly 10 also includes a connecting tube 160 and a docking member 170 disposed outside the first housing 110. The connecting tube 160 has a first tube body 161 and at least one second tube body 162 communicating with the first tube body 161. The first tube body 161 is arranged along the axial direction of the endoscope tube 140. One end of the first tube body 161 is connected to the insertion tube 130. The endoscope tube 140 passes through the first tube body 161. One end of the docking member 170 is detachably connected to the first housing 110, and the other end of the docking member 170 is detachably connected to the other end of the first tube body 161. A gap is formed between the endoscope tube 140 and the insertion tube 130. The gap communicates with the first tube body 161. The gap, the first tube body 161, and the second tube body 162 communicate to form a channel structure.

[0062] In this design, the first tube body 161 and the second tube body 162 of the connecting tube 160 are connected and cooperate to form a three-way tube structure, for example, the first tube body 161 and the second tube body 162 cooperate to form a Luer three-way tube. In this application, there may be multiple second tube bodies 162, which are spaced apart along the axial direction of the first tube body 161. The multiple second tube bodies 162 form multiple communication paths with the first tube body 161, thereby adapting to different installation scenarios and improving the applicability of arthroscopy.

[0063] Furthermore, the second tube 162 is set at an angle to the first tube 161. Specifically, the first tube 161 and the second tube 162 can be perpendicular, or the first tube 161 and the second tube 162 can be connected at an acute angle.

[0064] Specifically, the end of the first tube 161 connected to the insertion tube 130 communicates with the gap formed between the insertion tube 130 and the outer peripheral wall of the endoscope tube 140. The end of the second tube 162 away from the first tube 161 is open. The gap, the first tube 161, and the second tube 162 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 162 is exposed outside the first housing 110 and can be used to connect a fluid supply device or a suction device. This application improves the stability of fluid supply and suction by utilizing the channel structure formed between the endoscope tube 140, the insertion tube 130, the first tube 161, and the second tube 162, thereby improving the versatility of arthroscopy, the stability of operation, and the efficiency of arthroscopy use.

[0065] In this embodiment, the docking member 170 is used to connect the connecting pipe 160 and the first housing 110, specifically through a threaded connection structure. One end of the docking member 170 is threaded to the first housing 110, and the other end of the docking member 170 is threaded to the inner wall of the first pipe 161. The threaded connection method is convenient to install and has good connection strength, ensuring the stability of the connection between the insertion pipe 130, the connecting pipe 160, the docking member 170, and the first housing 110.

[0066] In this embodiment, the puncture assembly 10 also includes a sealing ring 180, which is disposed between the inner wall surface of the first tube 161 and the outer wall surface of the docking member 170. By setting the sealing ring 180, the sealing between the first tube 161 and the docking member 170 is further guaranteed, so as to ensure that there will be no leakage problem in the connection area between the first tube 161 and the docking member 170, thereby improving the efficiency of arthroscopy.

[0067] like Figures 3 to 6 As shown, the puncture assembly 10 also includes a mounting plate 1100 and a light source 190. The mounting plate 1100 is disposed inside the first housing 110, and the light source 190 is disposed on the mounting plate 1100. The first circuit board 150 is electrically connected to the light source 190, and the light source 190 is disposed opposite to the open end of the first end of the endpiece tube 140.

[0068] The mounting plate 1100 is mounted on the first housing 110 by bolts, and the light source 190 is fixed on the mounting plate 1100 to form a positioning installation of the light source 190. The light source 190 is aligned with the opening of the second mirror tube 140 to facilitate observation of the internal structure of the joint.

[0069] In this embodiment, the inner wall of the first housing 110 has a limiting groove, and the first circuit board 150 is disposed in the limiting groove. The limiting installation of the first circuit board 150 is achieved through the mounting groove, ensuring the stability of the installation of the first circuit board 150. To further improve the installation strength of the first circuit board 150, bolts or other structural components can also be used to lock the first circuit board 150 to the first housing 110.

[0070] In this embodiment, the arthroscope further includes an image sensor, an endoscope body, a first circuit board 150, and a light source 190. The image sensor and the endoscope body are disposed inside the second tube 162. The first circuit board 150 is disposed inside the first housing 110 and is signal-connected to the image sensor. The light source 190 is disposed inside the first housing 110 and is signal-connected to the first circuit board 150 and the light source 190.

[0071] 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.

[0072] Specifically, the first circuit board 150, a wireless PCB, is located on the first upper housing 111 of the insertion pin, establishing a signal connection with the image sensor and responsible for processing and transmitting image data. The light source 190 is located in the first lower housing 112, with its light-emitting end spaced axially from the second end opening of the endoscope tube 140. It is connected to the control circuit of the light source 190 through the first circuit board 150, ensuring the stability and controllability of the light source 190 while avoiding the operational inconvenience caused by wired connections. The use of the light source 190, 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.

[0073] In this embodiment, the light source 190 is mounted on the first lower housing 112 via the mounting plate 1100; the first circuit board 150 is mounted on the first upper housing 111. This application uses the first upper housing 111 and the first lower housing 112 to fix the light source 190 and the first circuit board 150 respectively, which makes reasonable use of the space inside the first housing 110 and improves the space utilization rate of the internal cavity of the first housing 110.

[0074] In this embodiment, as Figures 8 to 14As shown, the controller assembly 20 includes a second housing 210, a power supply 230, and a second circuit board 220. Along the axial direction of the mirror tube 140, the second housing 210 is detachably disposed on one side of the first housing 110. An operation part 280 is provided on the second housing 210. The power supply 230 is disposed inside the second housing 210. The second circuit board 220 is disposed inside the second housing 210. The second circuit board 220 is plugged into the first circuit board 150. The power supply 230 is electrically connected to the second circuit board 220 for power supply. The operation part 280 is used to connect or disconnect the second circuit board 220.

[0075] Specifically, the controller component 20 is formed as an independent structure, realizing the modular setting of the arthroscope. The second circuit board 220 is a wireless control PCB board. The first circuit board 150 is provided with a plug interface 151. The second circuit board 220 and the first circuit board 150 are plugged in to form a signal connection. The second circuit board 220 can transmit wireless signals with the host of the terminal device.

[0076] Meanwhile, the first housing 110 and the second housing 210 are detachably connected, which can be by fasteners such as bolts or by snap-fit.

[0077] In this embodiment, the second housing 210 includes a second upper housing 211 and a second lower housing 212, which cooperate to form the inner cavity of the second housing 210. The detachable connection of the second upper housing 211 and the second lower housing 212 facilitates the installation and removal of the internal structural components of the second housing 210.

[0078] Specifically, the second upper housing 211 and the second lower housing 212 are detachably connected by fasteners such as bolts. The second upper housing 211 and the second lower housing 212 are provided with aligning threaded holes, and the fasteners engage with these threaded holes to lock the second upper housing 211 and the second lower housing 212 in place. This fastener structure strengthens the connection between the second upper housing 211 and the second lower housing 212 and facilitates their assembly and disassembly.

[0079] Specifically, the second upper housing 211 and the second lower housing 212 are connected by a slot and a snap-fit ​​mechanism. One of the upper housing 211 and the lower housing 212 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 211 and the second lower housing 212 without adding any structural components, thus simplifying the operation and improving efficiency.
