Description

Technical Field

[0001] The utility model relates to the field of medical devices, and more specifically, to an integrated arthroscope. Background Art

[0002] An arthroscope is a rod-shaped optical instrument for observing the internal structure of joints. The rod body generally has a diameter of about 5 mm and is an endoscope used for diagnosing and treating joint diseases. An arthroscope is equipped with a lens at the end of a thin tube. When the thin tube is inserted into the joint, the internal structure of the joint will be displayed on the monitor, and the internal structure of the joint can be directly observed.

[0003] For example, Chinese patent document (publication number: CN 118161118 A) discloses a wireless arthroscopic surgical instrument, which includes an arthroscope body. An eyepiece mechanism is arranged at the lower left end inside the arthroscope body. The eyepiece mechanism includes an eyepiece tube, an eyepiece adapter tube, and an optical corridor. An eyepiece glue body is arranged inside the right end of the eyepiece tube. The other end of the arthroscope body away from the eyepiece glue body is provided with an objective lens mechanism. The objective lens mechanism includes an endoscope tube and an outer lens tube. A light source mechanism is arranged directly above the top end of the arthroscope body close to the eyepiece tube. The light source mechanism includes a light cone, an optical fiber, and a light guide beam joint. This device places the light source device inside the wireless arthroscope handle, which reduces the volume of the arthroscope to a certain extent.

[0004] However, the arrangement of the above-mentioned mechanisms is relatively complicated, so that the limited space of the arthroscope body is not fully utilized. When a user holds the arthroscope body, the hand feeling is poor. At the same time, the heat generated by the light source mechanism also reduces the service life of the circuit components.

[0005] In view of the above problems, the related art does not provide an effective solution. Summary of the Utility Model

[0007] Furthermore, the holding member is formed with a first expansion section and a second expansion section; the first expansion section and the second expansion section are connected by an arc transition, and the connected part is recessed inward to form a contraction part.

[0008] Furthermore, the keypad is located within the first expansion section, the signal transfer board is located within the second expansion section, and the light source is disposed within the contraction section.

[0009] Furthermore, the longitudinal cross-sections of the first expansion section and the second expansion section are circular, and the maximum diameter of the first expansion section is smaller than the maximum diameter of the second expansion section.

[0010] Furthermore, a second heat dissipation plate is provided on the side of the light source facing away from the first heat dissipation plate, and the light source is clamped between the first heat dissipation plate and the second heat dissipation plate.

[0011] Furthermore, the optical fiber filament group is composed of optical fiber filaments bonded with glue. The interior of the optical fiber filament group penetrates axially, and an avoidance space is formed on the inner wall of the optical fiber filament group for avoiding the imaging module.

[0012] Furthermore, a fitting hole is formed at the center of the second heat dissipation plate, and the optical fiber filament passes through the fitting hole and is connected to the light source.

[0013] Furthermore, the avoidance space is a cylinder or a cuboid.

[0014] Furthermore, the keypad is provided with circular rubber buttons, and the holding member is formed with mounting holes. The rubber buttons pass through the mounting holes; the diameter of the mounting holes is smaller than the diameter of the rubber buttons.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances so as to implement the embodiments of the present application described herein.

These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated devices, elements, or components must have a specific orientation, or be constructed and operated in a specific orientation. Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0035] This application provides an integrated arthroscope, as Figure 1 shown, which includes a grip member 100, a host wiring harness 200, and a steel pipe 300. Specifically, one end of the grip member 100 is connected to the host wiring harness 200, and the other end is connected to the steel pipe 300.

[0036] As Figure 1 、 2 shown, the grip member 100 is peanut-shaped and is used for the user to hold. Its interior forms a cavity 100a. Specifically, as Figure 3 shown, the grip member 100 is formed with a first expansion section 110 and a second expansion section 120. The first expansion section 110 and the second expansion section 120 are connected by an arc transition, and the connected part is recessed inward to form a contraction section 130. The space inside the grip member 100 is also peanut-shaped with large ends and a small middle.

[0037] Optionally, the surface of the grip member 100 is smooth, or, alternatively, anti-slip treatment can be performed on some of its areas to enhance the friction with the user's hand and prevent the user from dropping it during use.

[0038] As Figure 4 shown, a photography module 310 is provided inside the steel pipe 300, and an optical fiber filament group 320 is arranged around the outside of the photography module 310. Specifically, the outer edge of the optical fiber filament group 320 is cylindrical and is used for cooperation with the steel pipe 300.

[0039] As Figure 2 shown, the signal transfer board 400 is located on the side of the cavity 100a close to the host wiring harness 200. Specifically, the signal transfer board 400 is located inside the second expansion section 120.

[0040] As Figure 2As shown, the keypad 500 is electrically connected to the signal transfer board 400 and is located on the side of the cavity 100a close to the steel pipe 300. Specifically, the keypad 500 is located within the first expansion section 110.

[0041] Specifically, the light source 600 and the imaging module 310 are also respectively electrically connected to the signal transfer board 400. The signal transfer board 400 integrates a WiFi module, an image processing module, etc., which will not be elaborated herein in this application.

[0042] As Figure 2 shown, a light source 600 is provided between the keypad 500 and the signal transfer board 400. A first heat dissipation plate 700 is provided on the side of the light source 600 close to the signal transfer board 400. Specifically, the light source 600 is disposed within the contraction section 130. The heat dissipation plate is preferably made of aluminum material with a higher heat dissipation rate.

[0043] In this way, the holding member 100 adopts a peanut-like shape, which fits the user's palm and provides sufficient space for the layout of the internal structure. Among them, the signal transfer board 400 and the keypad 500 are relatively large in size and are respectively located in the larger spaces at both ends inside the holding member 100, while the light source 600 is located in the relatively narrow space in the middle, making it not easy to come into contact with the user's hand, avoiding the situation of heat conduction between the user's hand and the light source 600, which can greatly increase the comfort of the user. At the same time, a first heat dissipation plate 700 is provided near the light source 600 to reduce the influence of the heat generated by the light source 600 on the components inside the holding part. Moreover, the position of the first heat dissipation plate 700 between the light source 600 and the signal transfer board 400 further reduces the possibility of damage to the signal transfer board 400 caused by the heat generated by the light source 600.

[0044] Preferably, the longitudinal cross-sections of the first expansion section 110 and the second expansion section 120 are circular. As Figure 3 shown, the maximum diameter of the first expansion section 110 is smaller than the maximum diameter of the second expansion section 120, such that the first expansion section 110 has a smaller volume and can be more flexibly manipulated by the user's finger, and the second expansion section 120 fits with a larger range of the user's hand, making the user's grip more stable.

[0045] Specifically, as Figure 2 shown, a second heat dissipation plate 800 is provided on the side of the light source 600 facing away from the first heat dissipation plate 700, and the light source 600 is clamped between the first heat dissipation plate 700 and the second heat dissipation plate 800, and the heat of the light source 600 is further dissipated.

[0046] Further, the optical fiber filament group 320 is composed of optical fiber filaments bonded with glue. The optical fiber filaments can make the overall size of the optical fiber filament group 320 easy to adjust, and the diameter can be reduced to about 1 mm. Among them, the optical fiber filament group 320 penetrates axially inside, and an avoidance space is formed on the inner wall of the optical fiber filament group 320 for avoiding the photography module 310. Optionally, the avoidance space is a cylinder or a cuboid, which is used for stable cooperation with the photography module 310.

[0047] As a preferred solution, the diameter of the steel pipe 300 is less than 2 mm, such as 1 mm, 1.5 mm, 1.8 mm, etc., which is equivalent to the arthroscope in the prior art and has a smaller size, meeting various user requirements.

[0048] More specifically, a fitting hole is formed at the center of the second heat dissipation plate 800, and the optical fiber filament passes through the fitting hole and is connected to the light source 600 to further reduce the heat generated when the optical fiber works.

[0049] Further, as Figure 2 shown, the button board 500 is provided with a circular rubber button 510, and the holding member 100 is formed with a mounting hole, and the rubber button 510 passes through the mounting hole. The diameter of the mounting hole is smaller than the diameter of the rubber button 510, and the rubber button 510 can play a certain sealing role to prevent dust from entering the holding part.

[0050] In this application, the terms "mount", "set", "provided with", "connected", "connected to", "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is an internal connection between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0051] The above are only the preferred embodiments of this application and are not used to limit this application. For those skilled in the art, this application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this application shall be included in the protection scope of this application.
