Abstract

A flexible endoscope structure mainly comprises an outer tube, a first flexible tube combined with the outer tube, and a second flexible tube penetrating through the outer tube and the first flexible tube. Wherein the inner edge of the end part of the outer pipe is provided with a step part, so that a first caulking groove and a second caulking groove are formed; the first flexible pipe is provided with a metal hose piece formed by spirally winding a sheet-shaped body and a rubber pipe piece wrapping the metal hose piece, and the metal hose piece protrudes out of the bottom end of the rubber pipe piece by a proper length. The end portion of the second flexible tube is provided with a photographic lens. The second flexible pipe is arranged in the first flexible pipe in a penetrating mode, then the protruding and exposing section of the metal hose piece of the first flexible pipe and the bottom end of the rubber pipe piece of the first flexible pipe are embedded in the first embedding groove and the second embedding groove of the outer pipe respectively, and therefore the flexible endoscope is formed. Therefore, the front section of the endoscope can be freely adjusted to different angles due to plasticity, and the rear section of the endoscope can be positioned due to rigidity, thereby being beneficial to intubation medical operation.

Description

Technical Field

[0001] The present invention relates to a flexible endoscope structure, and more particularly to a flexible endoscope structure that enables the front section of the endoscope to be freely adjusted to different angles due to its plasticity, while the rear section can be kept in place due to its rigidity, thereby facilitating intubation medical operations. Background Art

[0002] Endoscopes for general medical use5, such as Figure 7 As shown, a tube body 51 of appropriate length is provided, and components such as filters, lenses 52 and light-emitting elements are provided at the front end of the tube body 51, and a connector 53 for connecting a control circuit is provided at the rear end. When in use, the endoscope 5 is inserted into the patient's mouth, and the control circuit is connected to a host with a display screen. The image of the organ is read by the lens 52 after being illuminated by the light-emitting element, and then the image signal is transmitted to the control circuit provided at the rear end of the endoscope 5, and the image is viewed on the display screen of the host.

[0003] In the existing endoscope 5, the tube body 51 is usually made of a very thin stainless steel material covered with a rubber layer. Although the tube body 51 can be slightly bent to adjust different angles due to its extremely thinness, the endoscope 5 can adapt to the intubation angles of patients in different states (such as patients with lung diseases and patients who cannot lie flat due to car accidents, or male and female patients, or patients with anatomical abnormalities such as retracted chins, limited neck movement, etc., the angles for intubation medical operations are all different). However, since the existing tube body 51 is made of a single material, that is, the hardness of its front and rear sections is the same, if the tube body 51 is made of a softer material, although it can be adjusted appropriately, it will be difficult to keep the rear section in place, making it difficult to control the entire endoscope 5, resulting in difficulty in inserting the entire endoscope 5; and if the tube body 51 is made of a harder material, although it can be better positioned during operation, it may hurt the patient during insertion and removal due to the overly hard material. Furthermore, there is currently no endoscope 5 designed with different hardnesses according to different intubation medical operations. In this regard, the applicant, through continuous research and experimentation, has designed a flexible endoscope structure, which allows the endoscope to be adjusted to different angles, thereby facilitating intubation medical operations. Summary of the invention

[0004] The main purpose of the present invention is to provide a flexible endoscope structure so that the endoscope can be adjusted to different angles according to the needs of patients in different conditions. The front section can be freely adjusted to different angles due to its plasticity, while the rear section can be kept in place due to its rigidity, thereby facilitating intubation medical operations and being safer.

[0005] The flexible endoscope structure mentioned above comprises an outer tube and a first flexible tube combined with the outer tube, and a second flexible tube inserted through the outer tube and the first flexible tube. The outer tube is provided with a step portion at the inner edge of the end to form a first embedding groove and a second embedding groove; the first flexible tube is provided with a metal hose component formed by spirally winding a sheet body, and a rubber tube component wrapped around the metal hose component, so that the metal hose component protrudes from the bottom end of the rubber tube component by an appropriate length; the second flexible tube is provided with a camera lens at the end. The second flexible tube is inserted through the first flexible tube, and then the protruding section of the metal hose component of the first flexible tube and the bottom end of the rubber tube component are respectively inserted into the first embedding groove and the second embedding groove of the outer tube to form a flexible endoscope. Through the plasticity of the first flexible tube and the second flexible tube, the front section of the endoscope can be freely adjusted to different angles due to the plasticity, and the rear section can be kept in position due to the rigidity, thereby facilitating the intubation medical operation.

[0006] In the aforementioned flexible endoscope structure, the second flexible tube is made of a plastic metal material, so that the second flexible tube can be made into the best plastic hardness according to the different genders or conditions of patients.

[0007] In the aforementioned flexible endoscope structure, the second flexible tube is preferably made of copper material with higher plasticity.

The metal hose component of the first flexible tube is embedded in the first embedding groove of the outer tube, and the bottom end portion of the rubber tube component is embedded in the second embedding groove of the outer tube.

[0009] In the aforementioned flexible endoscope structure, the length of the metal hose protruding from the bottom end of the rubber tube is equal to or slightly less than the height of the first embedding groove of the outer tube. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The technical scheme in the embodiment of the present invention is described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0019] Please also see Figure 1 and Figure 2 , and cooperate with Figure 3 , which are the three-dimensional exploded view and three-dimensional view of the present invention. As shown in the figure, the present invention comprises an outer tube 1 and a first flexible tube 2 combined with the outer tube 1, and a second flexible tube 3 penetrating the outer tube 1 and the first flexible tube 2. The outer tube 1 is provided with a step 11 at an appropriate position of the inner edge of the top, and the step 11 is used to form a first embedding groove 12 and a second embedding groove 13 of appropriate height; the bottom end of the outer tube 1 is provided with a smaller diameter inwardly contracted section 14 for connecting a plug connector 15, and the plug connector 15 is connected to a control circuit. In this embodiment, the outer tube 1 is made of stainless steel.

[0020] The first flexible tube 2 is provided with a metal hose 21 formed by spirally winding a metal sheet, and a rubber tube 22 covering the metal hose 21, so that the metal hose 21 protrudes from the bottom end of the rubber tube 22 by an appropriate length. In this embodiment, the length of the metal hose 21 protruding from the bottom end of the rubber tube 22 is equal to or slightly less than the height of the first embedding groove 12 of the outer tube 1.

[0021] The second flexible tube 3 is provided with a camera lens 31 at the end thereof, and is made of a plastic metal material. In this embodiment, the second flexible tube 3 is preferably made of copper material with higher plasticity, so that the second flexible tube 3 can be made into the best hardness for shaping according to the different genders or conditions of patients, such as: S0, S1, S2, S3, etc.

[0022] Through the aforementioned components, during assembly, the second flexible tube 3 is inserted into the first flexible tube 2, and then the exposed section of the metal hose component 21 of the first flexible tube 2 and the bottom end of the rubber tube component 22 are respectively embedded in the first embedding groove 12 and the second embedding groove 13 of the outer tube 1 to form a flexible endoscope A. Through the plasticity of the first flexible tube 2 and the second flexible tube 3, the front section of the endoscope can be freely adjusted to different angles due to the plasticity, while the rear section can be kept in place due to the rigidity, thereby facilitating the intubation medical operation.

[0023] See also Figure 4 , is a cross-sectional view of the outer tube and the first flexible tube of the present invention. As shown in the figure, during assembly, the protruding section of the metal hose 21 of the first flexible tube 2 is embedded in the first embedding groove 12 of the outer tube 1, and the bottom end of the rubber tube 22 is embedded in the second embedding groove 13 of the outer tube 1. Among them, since the length of the metal hose 21 protruding from the bottom end of the rubber tube 22 is equal to or slightly smaller than the first embedding groove 12 of the outer tube 1, the protruding section of the metal hose 21 and the bottom end of the rubber tube 22 can be tightly embedded in the first embedding groove 12 and the second embedding groove 13.

[0024] See also Figure 5 , which is a cross-sectional view after assembly of the present invention. As shown in the figure, after the exposed section of the metal hose 21 of the first flexible tube 2 is embedded in the first embedding groove 12 of the outer tube 1, and the bottom end of the rubber tube 22 is embedded in the second embedding groove 13 of the outer tube 1, the outer tube 1 near the top (the connecting section between the outer tube 1 and the first flexible tube 2) is appropriately pressed to form a ring-shaped or multiple-point-shaped concave, so that the outer tube 1 can clamp the first flexible tube 2, and then the entire structure is glued and fixed.

[0025] See also Figure 5, is a diagram of the use state of the present invention. As shown in the figure, when the present invention is used, the flexible endoscope A is inserted into the endotracheal tube 4 for insertion into the patient's trachea for intubation treatment, and the rear end connector 15 is connected to a control circuit, and the control circuit is connected to a host with a display screen. When in use, the flexible endoscope A is inserted into the patient's mouth together with the endotracheal tube 4, the image of the organ is read through the lens 31, and then the image signal is transmitted to the control circuit, and the image is observed on the display screen of the host. Among them, since the flexible endoscope A is composed of the first flexible tube 2 of the front section and the outer tube 1 of the rear section, and the second flexible tube 3 inserted in the first flexible tube 2 and the outer tube 1, the front section of the flexible endoscope A can be freely adjusted to different angles due to its plasticity, and the rear section can be kept in place due to the appropriate rigidity of the outer tube 1. Therefore, medical personnel can appropriately select a flexible endoscope A with a second flexible tube 3 of different hardness according to patients of different genders or states. For example, patients with lung diseases and patients who cannot lie flat due to car accidents, male and female patients, or patients with anatomical abnormalities such as retracted chins and limited neck movement can choose flexible endoscopes A of different hardness according to the different conditions of the patients. And during the intubation process, the angle of the front section can be adjusted appropriately to facilitate intubation. Among them, since the front section of the flexible endoscope A is flexible and the rear section is a harder outer tube 1 (stainless steel), during the intubation process, the rear section of the flexible endoscope A can be kept in place to facilitate insertion, and the front section is flexible, making the entire flexible endoscope A easy to control, and it will not hurt the patient when plugging and unplugging, making it safer.

[0026] The above embodiments are only for illustrating the preferred implementation of the present invention, and are not intended to limit the scope of the present invention. Slight modifications and changes will not lose the essence of the present invention and will not deviate from the spirit of the present invention.

[0027] In summary, the present invention uses an outer tube in conjunction with a flexible first flexible tube and a second flexible tube to form a flexible endoscope structure, so that the endoscope can be adjusted to different angles according to the needs of patients in different conditions, thereby facilitating intubation medical operations and making them safer.
