In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0045] The advantages and features of the present invention will become more apparent from the following description and claims.

[0046] Example

[0047] See Figures 1 to 3 This embodiment provides an integrated ureteroscope handle, which mainly includes: a main channel 2 and an outer shell 1.

[0048] Among them, the main pipeline 2 includes a first pipeline port and a second pipeline port at both ends, which can be used to install endoscope parts. The endoscope parts can be passed through the second pipeline port, the main pipeline 2 and the first pipeline port in sequence and then into the ureter.

[0049] Then, see Figure 1The outer shell 1 is wrapped around the outside of the main line 2 and is provided with a first handle port 101 and a second handle port 102 corresponding to the main line 2. That is, the first line port is located in the first handle port 101, and the second line port is located in the second handle port 102. The first handle port 101 and the second handle port 102 have fool-proof designs, which facilitate the direct installation of endoscope parts from the front or back.

[0050] In addition, Figure 1 As shown, above the main line 2, the outer shell 1 protrudes upward to form a first raised portion 103. Above the main line 2, the portion of the outer shell 1 adjacent to the first raised portion 103 forms an upper gripping area. The second and third raised portions 104, 105 are located below the main line 2 relative to the first raised portion 103. The portion of the outer shell 1 between the second and third raised portions 104, 105 forms a lower gripping area. The first and second raised portions 103, 104 are located near the first handle port 101, while the third raised portion 105 is located near the second handle port 102.

[0051] See Figure 1 Specifically, the first raised portion 103 includes a first arcuate segment, a first mounting port, and a second arcuate segment. The first arcuate segment is located on the left side of the first raised portion 103, with its two ends connected to the first mounting port and the handle port, respectively. The second arcuate segment is located on the right side of the first raised portion 103, with its two ends connected to the first mounting port and the upper grip area, respectively.

[0052] The first installation port is located between the first arc segment and the second arc segment, and can provide an installation port for external water supply components or cable connection components.

[0053] Preferably, see Figure 1 and Figure 2 In this embodiment, a first metal insert 4 is further provided in the first protrusion 103, which includes a first threaded member and a first rod member connected to each other. One end of the first rod member is connected to the upper side wall of the main line 2, and the other end of the first rod member is connected to the first threaded member, and the first threaded member is just arranged in the first installation port. As can be seen from the figure, a guide plane is provided on the first rod member, and its function is to provide guidance for the external water supply components or cable connection components connected thereto. The outer wall and the inner wall of the first threaded member are both provided with a threaded structure, and its function is to realize threaded connection of the water supply components or cable connection components connected thereto. It is worth mentioning that the first rod member and the first threaded member are both hollow structures, and the hollow channels of the two are connected, and the hollow channel of the first rod member is connected to the inside of the main line 2, thereby realizing conduction between the main line 2 and the first installation port.

[0054] See Figure 1The second raised portion 104 includes a third arc segment and a fourth arc segment. The third arc segment is located on the left side of the second raised portion 104, with its two ends connected to the handle port and the vertex of the second raised portion 104, respectively. The fourth arc segment is located on the right side of the second raised portion 104, with its two ends connected to the vertex of the second raised portion 104 and the lower gripping area, respectively.

[0055] See Figure 1 Specifically, the third raised portion 105 includes a fifth arcuate segment and a second mounting port. The fifth arcuate segment is located to the left of the third raised portion 105, with its two ends connected to the lower grip area and the vertex of the third raised portion 105, respectively. The second mounting port is located to the right of the third raised portion 105, near the second handle port 102. Similarly, this second mounting port provides a mounting port for connecting water supply components or cable connection components.

[0056] Preferably, see Figure 1 and Figure 3 Preferably, a second metal insert 5 is further provided in the third protrusion 105, which includes a second threaded member and a second rod member connected to each other. One end of the second rod member is connected to the lower side wall of the main line 2, and the other end of the second rod member is connected to the second threaded member, and the second threaded member is just arranged in the second installation port. As can be seen from the figure, the outer wall of the second threaded member is provided with a plurality of guide planes, which provide connection guides for the external water supply components or cable connection components connected thereto. The inner wall of the first threaded member is provided with a threaded structure, which can be threadedly connected to the external water supply components or cable connection components connected thereto. Similarly, the second rod member and the second threaded member are both hollow structures, and the hollow channels of the two are connected, and the hollow channel of the second rod member is connected to the interior of the main line 2, thereby realizing the conduction between the main line 2 and the second installation port.

[0057] See Figure 1 Preferably, an inner lining member 3 is further provided inside the outer shell 1. The inner lining member 3 is injection-molded inside the outer shell 1, which can effectively prevent the outer shell 1 from shrinking due to the thicker local wall thickness.

[0058] The principle of this embodiment is now explained: When an operator uses this embodiment, the second arc segment, upper gripping area, third arc segment, fourth arc segment, lower gripping area, and fifth arc segment are provided to fit the operator's hand gripping posture. When the operator grips, the palm fits the upper gripping area and the base of the thumb fits the second arc segment. At this time, the fingers grip the lower gripping area and the thumb rests on the third arc segment or the fourth arc segment, thereby facilitating a comfortable force point for the operator's fingers and base of the thumb. In addition, the outer shell 1 is formed by injection molding using high-temperature materials, which reduces the overall weight of the handle while ensuring the strength, toughness, and durability of the handle. On the one hand, the first metal insert 4 and the second metal insert 5 prevent the outer shell 1 from shrinking due to the thicker local wall thickness. On the other hand, because the two inserts are provided with threads and guide structures, they are convenient for direct installation and matching with the water supply components and cable connection components on the endoscope, ensuring the strength of the overall endoscope structure after installation.

[0059] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they will still fall within the scope of protection of the present invention.
