It can enter the stomach through the mouth or other natural orifices to enter the body, thereby presenting lesions to doctors. An endoscope usually includes a lens system, a light guide, a snake bone or a control handle, among which the snake bone of the endoscope is a series of connected small sections that allow the endoscope to bend flexibly and control the direction in the body cavity, and the control handle is used to operate the snake bone, which is usually designed to be easy for doctors to operate in order to accurately control the movement and function of the endoscope.

[0003] For example, a Chinese patent document (publication number: CN 117297513 A) provides an endoscope transmission assembly and an endoscope, which is provided with at least two traction ropes and connected to different opposite sides of the snake bone in the radial direction, and cooperates with the corresponding transmission assembly to realize the rotation of the snake bone in two or more planes, that is, it can be bent and adjusted in multiple planes. However, the endoscope is heavy, and the doctor needs to apply force to the driving wheel when holding the endoscope, so that the snake bone is deformed through the gear transmission assembly, and the doctor will have hand pain after long-term use.

[0004] For the above problems, the related technologies do not provide effective solutions. Utility Model Content

[0007] Furthermore, the housing includes a first shell and a second shell, and the first shell and the second shell are combined to form a cavity; the rotating shaft passes through the first shell, so that the adjustment part and the driving wheel are respectively located on both sides of the first shell.

[0008] Furthermore, the movable pulley includes a pulley shaft; the mass of a side of the pulley shaft close to the first housing is greater than the mass of a side of the pulley shaft away from the first housing.

[0009] Furthermore, two fixing seats are provided on the inner side wall of the first shell, and the two fixing seats are used to fix the two ends of the winding wire respectively.

[0010] Furthermore, a plurality of guide seats are provided on the inner side wall of the first shell, the guide seats are located between the movable pulley and the snake bone, and the guide seats have guide grooves, and the first output line and the second output line pass through the guide grooves.

For example, the term "upper" may also be used to indicate a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific circumstances.

[0031] like Figure 1 As shown, this embodiment provides a labor-saving endoscope, including a housing 100, an adjustment portion 200, a flexible tube 300 and a snake bone 400. The adjustment portion 200 is rotatably connected to the outside of the housing 100 and is manually adjusted by the user. The adjustment portion 200 can be a handle, a knob, etc. The housing 100, the flexible tube 300 and the snake bone 400 are connected in sequence.

[0032] Specifically, if Figure 1 As shown, the housing 100 includes a first shell 110 and a second shell 120 , and the first shell 110 and the second shell 120 are combined to form a cavity 130 .

[0033] like Figure 2 , 3 As shown, a driving wheel 131 and a movable pulley are disposed in the cavity 130 . Specifically, the movable pulley includes a first movable pulley 133 and a second movable pulley 134 .

[0034] like Figure 3 As shown, the driving wheel 131 is fixedly connected to the adjustment part 200 through a rotating shaft, is located in the cavity 130, and is driven to rotate by the adjustment part 200. The driving wheel 131 is wound with a winding wire 132, and the two ends of the winding wire 132 extend from the two sides of the driving wheel 131 respectively, and the two ends of the winding wire 132 are fixed to the inner wall of the housing 100. When the driving wheel 131 rotates, the winding wire 132 rotates with the driving wheel 131. The winding wire 132 is a load steel wire, which has the characteristics of wear resistance, corrosion resistance and high strength, and can withstand large tension and load.

[0035] Further, such as Figure 2 As shown, two fixing seats 113 are provided on the inner side wall of the first shell 110. The two fixing seats 113 are used to fix the two ends of the winding wire 132 respectively. The fixing seats 113 are used to raise the winding wire 132. The winding wire 132 can be welded to the fixing seats 113 or glued to the fixing seats 113.

[0036] Specifically, the rotating shaft of the driving wheel 131 passes through the first housing 110 , so that the adjustment portion 200 and the driving wheel 131 are respectively located on two sides of the first housing 110 .

[0037] like Figure 2 As shown, the winding wire 132 supports the first movable pulley 133 and the second movable pulley 134 at the parts near its two ends respectively, the first movable pulley 133 is connected to the first output line 133a, the second movable pulley 134 is connected to the second output line 134a, the first output line 133a and the second output line 134a are connected to the snake bone 400 for controlling the deformation of the snake bone 400.

[0038] Preferably, if Figure 2 As shown, the first movable pulley 133 and the second movable pulley 134 are alternately arranged along the length direction of the handle 210, making the layout more compact.

[0039] Since most of the gravity of the movable pulley and the pulling force required for the deformation of the snake bone 400 are dispersed into the interior of the shell, the user only needs to use a small force to rotate the driving wheel 131 when holding the endoscope, thereby causing the first movable pulley 133 and the second movable pulley 134 to roll and displace through the winding wire 132. The first movable pulley 133 and the second movable pulley 134 respectively pull the first output line 133a and the second output line 134a to achieve multi-dimensional bending and twisting of the snake bone 400, so that the endoscope can be flexibly moved and operated in a tortuous environment, highly adaptable to the complex human body system, and the endoscope is further lightweight, greatly reducing the user's operating burden.

[0040] Preferably, if Figure 4 As shown, the movable pulley includes a pulley shaft 135, and the mass of the pulley shaft 135 close to the first housing 110 is greater than the mass of the pulley shaft 135 away from the first housing 110, which is used to increase the stability of the movable pulley and prevent rollover.

[0041] Among them, a plurality of guide seats are arranged on the inner side wall of the first shell 110, and the guide seats are located between the movable pulley and the snake bone 400. The guide seats have guide grooves, and the first output line 133a and the second output line 134a pass through the guide grooves, and the guide grooves are used to guide the movement direction of the output lines.

[0042] Specifically, if Figure 4As shown, the guide seat includes a single-line guide seat 111 and a double-line guide seat 112, the distance between the double-line guide seat 112 and the movable pulley is greater than the distance between the single-line guide seat 111 and the movable pulley, the first output line 133a or the second output line 134a passes through the guide groove of the single-line guide seat 111, and the first output line 133a and the second output line 134a pass through the guide groove of the double-line guide seat 112 together, so that the force on the snake bone 400 is more balanced.

[0043] Furthermore, one end of the flexible tube 300 is connected to the snake bone 400 , and the other end is inserted into the double-wire guide seat 112 of the housing 100 and fixedly connected to the double-wire guide seat 112 , so that the flexible tube 300 can be firmly supported by the first housing 110 .

[0044] Among them, Figure 5 As shown, the adjustment portion 200 is constructed as a handle 210, which is bent along the outer wall of the shell 100 toward the thickness direction of the shell 100 to form a gripping portion 220. The shell 100 is formed with a positioning protrusion 140 and a limiting protrusion 150 that cooperate with the gripping portion 220 to limit the rotation angle of the handle 210. The height of the positioning protrusion 140 is adapted to the rotation radius of the gripping portion 220. When the gripping portion 220 passes over the positioning protrusion 140, it will be interfered by the limiting protrusion 150 of the shell 100 and cannot continue to rotate, thereby preventing the handle 210 from rotating excessively and causing the user to frequently reset the handle 210, thereby further reducing the user's operating burden.

[0045] Preferably, a plurality of finger grooves 160 are provided on the side of the housing 100 away from the grip portion 220 , which are arranged along the length direction of the housing 100 , do not interfere with the adjustment portion 200 , and conform to ergonomic design, making it more comfortable for the user to grip the housing 100 .

[0046] In this application, the terms "installed", "set", "provided with", "connected", "connected", and "socketed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0047] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
