Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope tip and an endoscope. Background Technology

[0002] In modern medicine, various medical devices are widely used, such as endoscopes, which are inserted into the human body to observe disease conditions. An endoscope includes an endpiece, on which a light source and image sensor are integrated for illumination and imaging. In clinical use, power is supplied to the light source and image sensor via cables. The light source provides illumination, and the image sensor acquires and outputs the images externally.

[0003] However, the camera lens at the tip of traditional endoscopes is fixed and cannot be adjusted to the distance to the target of observation according to actual needs. This results in blurry images in some scenarios, making it difficult to conduct close-up, multi-angle detailed observation of specific areas, thus limiting the observation range and image quality. When facing narrow or tortuous spaces, the overall size of the tip of the endoscope is relatively large, making it difficult to penetrate deeply. Utility Model Content

[0004] This utility model discloses an endoscope tip and endoscope, which solves the problem that the traditional endoscope tip camera lens is fixed and cannot be adjusted to the distance to the observation target according to actual needs, resulting in blurry images in some scenarios and making it difficult to conduct close-up, multi-angle detailed observation of specific areas, thus limiting the observation range and image quality. Through the design of a retractable camera lens, the endoscope can flexibly adjust the position of the camera lens to adapt to different spatial environments, expand the observation range, and improve the inspection efficiency.

Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] It should be noted that, in this embodiment, those skilled in the art will understand that when performing surgery using an endoscope, the tip of the endoscope contacts the patient, and the rear end (handle assembly) is operated by the operator. For ease of description, the end of each component of the endoscope that is closer to the tip is referred to as the distal end, and the end of each component that is closer to the rear end of the endoscope is referred to as the proximal end.

[0035] This utility model discloses an endoscope tip, see [link to related information]. Figures 1-5 The endoscope tip includes a housing 1, a lens assembly 2, a drive assembly 3, and a control assembly (not shown). The housing 1 provides support and protection for the overall structure. The housing 1 has an inlet 11 for the lens assembly 2 to extend or retract. The lens assembly 2 can extend or retract through the inlet 11 under the drive of the drive assembly 3. The control assembly is used to control whether the drive assembly 3 extends or retracts the lens assembly 2. Through the telescopic lens design, the endoscope can flexibly adjust the lens position to adapt to different spatial environments and expand the observation range.

[0036] As one embodiment of this utility model, see Figure 2 The drive assembly 3 includes a motor 31, a lead screw 32, and a slider 33. The motor 31 drives the lead screw 32 to rotate clockwise (forward) or counterclockwise (backward). The slider 33 moves along the axial direction of the lead screw 32 under the drive of the lead screw 31. The control assembly controls the forward or reverse rotation of the motor 31 to make the slider 33 move towards the far end of the lead screw 32 or towards the near end of the lead screw 32.

[0037] As one embodiment of this utility model, the lens assembly 2 includes a lens mount 21, a lens 22, and an image sensor. The lens mount 21 is fixedly connected to a slider 33. See [link to relevant documentation]. Figure 2 The lens 22 is fixedly mounted at the far end of the lens mount 21, and the image sensor is set inside the lens mount 21. The image sensor converts the optical image captured by the lens 22 into an electrical signal for subsequent processing and display.

[0038] The control component controls the forward or reverse rotation of the motor 31, causing the slider 33 to move toward the far end or toward the near end along the lead screw 32. Since the lens mount 21 is fixedly connected to the slider, when the slider 33 moves toward the far end along the lead screw 32, the lens 22 will extend out of the inlet / outlet 11; when the slider 33 moves toward the near end along the lead screw 312, the lens 22 will retract into the inlet / outlet 11.

[0039] As an embodiment of this utility model, the endoscope tip also includes a dustproof component, which includes a sealing ring 41 and a dustproof baffle 42. A plurality of sealing rings 41 are fitted onto the outer peripheral surface of the lens mount 21, and these sealing rings 41 are tightly fitted against the inner side of the inlet / outlet 11 on the housing 1 to prevent liquid and dust from entering. The sealing rings 41 are preferably made of oil-resistant rubber. The dustproof baffle 42 has a thin sheet structure. See [reference needed]. Figures 3-4 The dustproof baffle 42 is similar in shape to the inlet / outlet 11, and one end of the dustproof baffle 42 is hinged to the upper or lower edge of the inlet / outlet 11, so that the dustproof baffle 42 is pushed open when the lens 22 is extended and automatically closed when the lens 22 is retracted, further enhancing the sealing effect of the endoscope tip; preferably, the dustproof baffle 42 includes a first baffle 421 and a second baffle 422, one end of the first baffle 421 is hinged to the upper edge of the inlet / outlet 11, and one end of the second baffle 422 is hinged to the lower edge of the inlet / outlet 11.

[0040] The specific working process of the endoscope tip with lens telescopic function disclosed in this utility model is as follows:

[0041] When observation using the endoscope tip is required, the control assembly controls the motor 31 to rotate in a first direction. The motor 31 drives the lead screw 32 to rotate in the first direction. The rotation of the lead screw 32 causes the slider 33 to move distally along the axis of the lead screw 32. Since the slider 33 is fixedly connected to the lens mount 21, the movement of the slider 33 distally causes the lens 22 to extend from the inlet / outlet 11 on the housing 1. See [reference needed] Figure 5This allows for closer observation of the target, resulting in clearer and more detailed images. After the endoscope tip has finished its observation, the control component controls the motor 31 to rotate in the second direction. The motor 31 drives the lead screw 32 to rotate in the second direction. The rotation of the lead screw 32 causes the slider 33 to move towards the proximal end along the axis of the lead screw 32. Since the slider 33 is fixedly connected to the lens mount 21, the movement of the slider 33 towards the proximal end causes the lens 22 to retract from the inlet 11 on the housing 1. When the lens 22 retracts into the housing 1, the sealing ring 41 and the dustproof baffle 42 work together to prevent external liquids and dust from entering the equipment and protect the internal components.

[0042] Another aspect of this invention discloses an endoscope comprising a lens 22 as described above, capable of extending or retracting from the tip of a housing 1.
