AI Technical Summary
Existing endoscopes are difficult to operate when maintaining a fixed bending angle, requiring the thumb to hold the rotating handle continuously, which makes them inconvenient to use.
An endoscope insertion section bending locking control structure was designed. Through the cooperation of the guide groove and the transmission column, the rotation of the handle drives the drive shaft to rotate, and the drive shaft drives the transmission column to move spirally, thereby locking the damping block and the control wheel and avoiding continuous pressing of the handle.
This makes it easier to maintain the bending angle of the endoscope, reducing the workload of operation.

Abstract
Description
Technical Field
[0001] This application relates to the field of locking control structure technology, and more specifically, to an endoscope insertion portion bending locking control structure. Background Technology
[0002] With the development of science and technology, endoscopes have been widely used in the medical field, serving as one of the important tools for examining internal organs. Generally, endoscopes with a flexible insertion section have a curved section at the front end of the insertion section. This curved section can bend as the operator performs their movements, allowing the endoscope to be positioned at a specific angle for easier further manipulation by the user.
[0003] Clinically, after identifying a suspected lesion, the user usually needs to keep the endoscope at a fixed angle to allow for further detailed observation or biopsy of the suspected lesion. This requires the user to hold down the rotating handle with their thumb to prevent rotation and keep the endoscope tip in a fixed bent position until the biopsy or further examination is completed. This operation is quite strenuous.
[0004] Therefore, a more labor-saving endoscope insertion section bending locking control structure is provided. Utility Model Content
[0005] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide an endoscope insertion section bending locking control structure, comprising: a fixed plate and an end cap; the end cap is located at one end of the fixed plate and is fixedly connected to the fixed plate; a guide sleeve is fixedly connected to the end cap; a drive shaft is slidably connected to the guide sleeve; a transmission column is fixedly connected to the drive shaft; a damping block is fixedly connected to the drive shaft; a handle is fixedly connected to the drive shaft; and a control wheel is rotatably connected to the fixed plate; wherein, the guide sleeve includes a guide groove; the transmission column is partially located within the guide groove and moves along the guide groove; and the damping block abuts against the control wheel.
[0007] Turning the handle causes the drive shaft to rotate, which in turn moves the transmission column. Under the action of the guide groove, the drive shaft moves spirally through the transmission column, thereby locking the damping block and the control panel. The control wheel can be locked without holding down the handle, making it more labor-saving.
[0008] Furthermore, the handle includes a first mounting hole; the drive shaft portion is located within the first mounting hole.
[0009] Furthermore, the drive shaft is fixedly connected to the handle by screws.
[0010] Furthermore, the guide sleeve includes a guide hole; the drive shaft includes a protrusion; the protrusion abuts against the guide hole to guide the drive shaft.
[0011] Furthermore, the drive shaft includes a second mounting hole; the damping block portion is located within the second mounting hole.
[0012] Furthermore, the handle is located at the upper end of the drive shaft; the damping block is located at the lower end of the drive shaft.
[0013] Furthermore, the endoscope insertion part bending locking control structure also includes: a sealing ring, the inner side of which abuts against the drive shaft, and the outer side of which abuts against the guide sleeve.
[0014] Furthermore, the drive shaft includes a mounting groove; the sealing ring is located within the mounting groove.
[0015] The beneficial effect of this application is that it provides a more efficient and labor-saving endoscope insertion section bending locking control structure. Attached Figure Description

[0032] Reference Figure 1-6An endoscope insertion section bending locking control structure 100 includes: a fixed plate 101, an end cap 102, a guide sleeve 103, a drive shaft 104, a transmission column 105, a damping block 106, a handle 107, a control wheel 108, and a sealing ring 109. The end cap 102 is located at one end of the fixed plate 101 and is fixedly connected to it. The guide sleeve 103 is fixedly connected to the end cap 102. The drive shaft 104 is slidably connected to the guide sleeve 103. The transmission column 105 is fixedly connected to the drive shaft 104. The handle 107 is located at the upper end of the drive shaft 104, and the damping block 106 is located at the lower end of the drive shaft 104. The damping block 106 is fixedly connected to the drive shaft 104. The handle 107 is fixedly connected to the drive shaft 104. The control wheel 108 is rotatably connected to the fixed plate 101.
[0033] The guide sleeve 103 includes a guide groove 103a, and a drive column 105 is partially located within the guide groove 103a and moves along the guide groove 103a. The guide groove 103a extends circumferentially and radially along the guide sleeve 103. A damping block 106 abuts against a control wheel 108. The handle 107 includes a first mounting hole 107a, and a drive shaft 104 is partially located within the first mounting hole 107a. The drive shaft 104 is fixedly connected to the handle 107 by screws. The guide sleeve 103 includes a guide hole 103b, and the drive shaft 104 includes a protrusion 104a, which is an annular structure. The protrusion 104a abuts against the guide hole 103b to guide the drive shaft 104.
[0034] The drive shaft 104 includes a second mounting hole 104b, and a damping block 106 is partially located within the second mounting hole 104b. A sealing ring 109 abuts against the drive shaft 104 on its inner side and against the guide sleeve 103 on its outer side. The drive shaft 104 includes a mounting groove 104c, and the sealing ring 109 is located within the mounting groove 104c. Two adjusting ropes are provided on the control wheel 108, which control the curvature of the endoscope (the specific structure can be found in Chinese Patent No. 106419818B, an angle-adjustable endoscope; the control block is equivalent to the control wheel 108 of this application). After adjusting the curvature of the endoscope, turn the handle 107. The rotation of the handle 107 drives the drive shaft 104 to rotate, which in turn drives the transmission column 105 to move. Under the action of the guide groove 103a, the drive shaft 104 will move spirally through the transmission column 105, thereby locking the damping block 106 and the control wheel 108. It is not necessary to keep pressing the handle 107 to lock the control wheel 108 and prevent its rotation, which is more labor-saving.
[0035] Workflow: First, adjust the curvature of the endoscope using the control wheel 108. After adjusting the curvature, turn the handle 107. The rotation of the handle 107 drives the drive shaft 104 to rotate, which in turn drives the transmission column 105 to move. Under the action of the guide groove 103a, the drive shaft 104 will move spirally through the transmission column 105, thereby locking the damping block 106 with the control wheel 108. The control wheel 108 can be locked without continuously pressing the handle 107, which is more labor-saving.
[0036] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
