Description

Technical Field

[0002] An endoscope is a specialized medical instrument that can examine or treat internal diseases through natural cavities or surgical incisions in the human body. With the development of microelectronics technology, electronic endoscopes are increasingly used in medical applications.

[0003] Existing neurosurgical endoscopes are rigid. For example, the STORZ endoscope, widely used in neurosurgery, consists of a front-mounted optical system and a rear-mounted processing system. The front end of the optical system is the approximately 250mm long lens end, which includes the objective lens system, light source fiber system, and the scope tube. The processing system includes an image sensor, processor, cold light source, and controller, and also integrates a handle and external device connectors. The scope tube consists of an endoscope tube and an external tube wrapped around the endoscope tube. Both the endoscope tube and the external tube are made of rigid materials. This results in the STORZ endoscope being larger and heavier overall, requiring numerous and complex external devices, and being relatively expensive.

[0004] For endoscopes with a rigid mirror structure, the lens angle and the mirror tube cannot be adjusted at will, resulting in poor freedom of observation angle and range. There are still blind spots in the surgical field. When using, it is often necessary to repeatedly replace different models of mirror bodies (such as 0°, 30°, 70°, etc.) to achieve the surgical purpose; it cannot be seamlessly connected with the surgical microscope, and one needs to be removed before using another.

[0005] In addition, existing endoscopes are heavy and cumbersome to use. They are difficult to control and fix when holding the endoscope for deep and delicate operations. Doctors need assistants to help hold the endoscope during surgery, which can easily lead to medical risks due to surgical errors. The technical threshold for doctors to use is high and the learning cycle is long. The structure is complex, with many external devices, and it takes up a lot of space in the operating room.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, rather than all of the contents.

[0050] Example 1

[0051] like Figure 1-4 As shown, a medical endoscope provided by an embodiment of the present invention includes a shapeable catheter 1 and a lens module, wherein the lens module is installed at the end of the shapeable catheter 1.

[0052] The diameter of the shapeable catheter 1 is 2-6 mm. The length of the shapeable catheter 1 is 200-500 mm. The wall thickness of the shapeable catheter 1 is 0.5-1.5 mm.

[0053] In the present invention, the shaped conduit 1 can take three main forms: a spring-mounted conduit; a plastic tube and metal wire fixed together; or a hollow metal tube. The spring-mounted conduit 1 provides the best results. All three forms employ a hollow structure, allowing the connecting cable 3 to pass through the conduit 1. The lens module is mounted at the front end of the conduit 1, and the shaped conduit connector 11 is mounted at the rear end. The connecting cable 3 is connected between the lens module and the adapter plate 12 of the shaped conduit connector 11.

[0054] The outer periphery of the shapeable catheter 1 is provided with a medical plastic layer 2. The medical plastic layer 2 can be made of LDPE low-density ether.

[0055] The depth of field of the lens module is 3-50 mm, and the field of view angle is 60-120 degrees. The lens module can be in various forms, and the lens module is preferably a 0-degree angle lens module or a 25-35-degree angle lens module.

Specific parameters of each lens module are shown in Table 1.

[0057] Table 1 Lens module models and parameters

[0058]

[0059]

[0060] This embodiment provides a specific lens module structure: Figure 5 As shown, the lens module includes a micro-objective lens 4 and a CMOS image sensor 10. The micro-objective lens 4 is positioned at the front end of the lens module, and the CMOS image sensor 10 is positioned at the rear end of the micro-objective lens 4. Multiple LED lights 6 are positioned around the micro-objective lens 4. Optical adhesive 5 is filled around the front periphery of the micro-objective lens 4 and the multiple LED lights 6. The LED lights 6 are front-facing light sources, providing illumination within the narrow space inside the human body to illuminate the inspection area.

[0061] The CMOS image sensor 10 and the LED light 6 are electrically connected to the circuit board 8 respectively. The circuit board 8 adopts an FPCBA module, which is a flexible circuit board that carries the fingerprint chip and other electronic components. The micro objective lens 4 and the circuit board 8 are arranged in a PEEK terminal 7 (PEEK terminal refers to a terminal made of polyetheretherketone material); the space between the PEEK terminal 7 and the circuit board 8 is filled with a filling adhesive 9. The micro objective lens 4 of the present invention completes optical imaging and projects it onto the CMOS image sensor 10; the CMOS image sensor 10 collects light signals, converts them into digital signals through AD (analog electrical signal to digital electrical signal conversion), and then outputs the signals to facilitate display and storage by the upper-level equipment. To ensure that the present invention can be implemented, the model OV9734 of the CMOS image sensor 10 is given as an example. The front side is the photosensitive surface, which can receive the image of the micro objective lens 4; the back side is the welding surface, and the solder joints of the CMOS image sensor 10 are dissolved and soldered to the pads of the circuit board 8 to achieve circuit connection.

[0062] The above lens module is preferably a 0-degree angle lens module. The medical endoscope of the present invention can also adopt a 25-35-degree angle lens module.

[0063] This embodiment provides a specific external joint structure: Figure 6 As shown, the external connector includes a shaped catheter connector 11 and a small adapter plate 12. The shaped catheter connector 11 is installed at the end of the shaped catheter 1. The small adapter plate 12 is disposed within the shaped catheter connector 11 and is electrically connected to the circuit board 8. The connecting cable 3 between the small adapter plate 12 and the circuit board 8 is placed in the shaped catheter 1. The shaped catheter connector 11 is used to connect to the connector cap 13 of the external device to achieve access to the external device.

[0064] The shapeable catheter 1 of the present invention is subjected to a three-point bending test or a two-point bending test; the bending force range of the three-point bending test is 20-350N, preferably 20-200N; the bending force range of the two-point bending test is 0.65-60N.

[0065] In the three-point bending test, a sample (the shapeable catheter 1 ) is placed between two supporting points and a load perpendicular to the sample is applied.

[0066] The two-point bending test is to subject both ends of the sample (the shapeable catheter 1) to force and generate bending deformation, so that the sample is bent 180 degrees, and the maximum force value after the sample is bent is recorded.

[0067] The present invention is described in the following experimental description:

[0074] 3. Experimental purpose: To evaluate the elastic properties, initial failure strength and fracture toughness of the material.

[0075] 4. Test results:

[0083] Experiment 1.4: Take three 30mm test sections from sample 4# and perform three-point bending test on each section. Figure 10 As shown, the results are as follows:

[0084]

[0085] Three-point bend test conclusion: The maximum bending force of sample 4# was significantly greater than the actual bending force of the sample tested. Furthermore, during manual bending, the sample exhibited high bending strength, requiring a significant bending force to achieve bending. Analysis indicated that further testing would be difficult to obtain valid data, so the three-point bend test for this sample and subsequent samples was terminated. The bending force range for the three-point bend test was 20-350N, preferably 20-200N.
