All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 6, the present embodiment provides a super-fine laparoscope, which includes a central connection housing 1, wherein an insertion tube mounting seat 101 is disposed at a front end of the central connection housing 1, a light guide connector 2 is disposed at a top of the central connection housing 1, an electrical connector housing 3 is disposed at a tail of the central connection housing 1, a universal connector 4 is disposed in the electrical connector housing 3, an insertion tube 5 is connected to the insertion tube mounting seat 101 in a penetrating manner, an imaging lens 6 is fixedly connected to an inner side of a front end of the insertion tube 5 in a sleeved manner, an imaging module protective cover 7 is disposed behind the imaging lens 6, an imaging module positioning support 8 is connected to an inner side of a tail end of the imaging module protective cover 7 in a sleeved manner, a micro imaging module 9 is mounted at a front end of the imaging module positioning support 8, a communication cable 10 is electrically connected to a rear side of the, The optical fiber imaging device comprises an insertion tube 5, a central connection shell 1 and a universal joint 4, wherein an optical fiber channel 71 is arranged between an imaging module protective sleeve 7 and the insertion tube 5, an optical fiber 11 is fixedly installed in the optical fiber channel 71, the tail end of the optical fiber channel 71 is correspondingly provided with an optical fiber fixing support 12, the front end of the optical fiber 11 is attached to an imaging lens 6, and the tail end of the optical fiber 11 sequentially penetrates through the insertion tube 5, the central connection shell 1 and a light guide joint 2.
Wherein, imaging module lag 7 has effectively protected inboard miniature imaging module 9, and isolated optic fibre 11's light simultaneously guarantees that light can only pass imaging lens 6 and reach miniature imaging module 9, promotes the imaging quality. The imaging lens 6, i.e. a commonly used optical lens in the market, can refract and focus light onto the micro imaging module 9, and provides a protective effect. The universal joint 4 can adopt a pluggable joint of a Cornit SZCNT 1P type and the like, so that the laparoscope can be conveniently disassembled and stored and carried for use. Due to the adoption of the miniature imaging module 9, the diameter range of the insertion tube 5 can be controlled to be 1.7mm-2.3mm, and the volume of the equipment is effectively reduced. The connection angle between the central connection shell 1 and the tail end of the light guide connector 2 is larger than 90 degrees, so that the optical fiber 11 is prevented from being excessively bent, and the light source is not easy to lose and damage during guiding.
The micro imaging module 9 is a micro camera module, and electronic image elements having areas of 1mm or less, such as an emmis semiconductor naneye m micro camera module, including a micro CMOS image sensor, can be adopted to ensure the small size of the device.
The optical fiber fixing support 12 comprises a hollow support 121, three positioning blades 122 with equal intervals are arranged on the outer side of the hollow support 121, and the positioning blades 122 are pressed against the inner side of the insertion tube 5. The optical fiber 11 passes through a passage formed between the hollow frame 121 and the inside of the insertion tube 5, and the positioning blade 121 provides support for the hollow frame 121, so that the hollow frame 121 is fixed in the insertion tube 5, and provides support for elements at the front end of the optical fiber fixing holder 12. In addition, the optical fiber 11 has positioning blades 122 on the left and right sides and the upper and lower sides respectively pass through the gaps of the insertion tube 5 and the hollow bracket 121, so that the optical fiber 11 is positioned and clamped, and shaking and displacement are avoided.
The outer side of the communication cable 10 is wrapped with a cable protection shell 13. The cable protection shell 13 can protect the communication cable 10 inside, and ensure stable signal transmission.
An electrical connector cover plate 14 is fixed to the end of the electrical connector housing 3, and the universal connector 4 is mounted in the center of the electrical connector cover plate 14. The electrical connector cover plate 14 can fix the universal connector 4, provide an operation surface, and facilitate grasping the universal connector 4 to plug and pull the butt cable.
The surface of the insertion tube 5 is provided with a graduated scale 15. The design of the graduated scale 15 facilitates the confirmation of the depth of the laparoscope into the abdominal cavity at any time.
The imaging optics 6 are integrally formed with the optical fiber 11. The optical fiber 11 is generally made of glass or plastic, and the type of the formed lens 6, i.e. the optical lens, is very close to the optical fiber 11, so in order to improve the transmission quality of the illumination light, the imaging lens 6 and the optical fiber 11 with the same or similar materials can be adopted, and the two are bonded and formed into a whole by means of fusion (i.e. the two are heated and melted and then butt-bonded, which belongs to the conventional technical means and is not described herein in detail) and the like.
When in actual use, the optical fiber 11 penetrating out of the light guide connector 2 is butted with an external light source device, and is connected with an external power supply and a display screen through the universal connector 4, and then the front end of the insertion tube 5 can be inserted into the hollow puncture outfit which enters into the focus position to reach the position to be checked.
The foregoing is a more detailed description of the invention than is specifically described in connection with the preferred embodiments, and it is not intended to limit the invention to the particular forms disclosed, since all equivalent variations and modifications as fall within the scope of the appended claims are intended to be embraced therein.
