Description

Technical Field

[0001] This utility model relates to the field of endoscope technology, and more specifically, to a four-way adjustable endoscope. Background Technology

[0002] Figure 6 This is a schematic diagram of the lens end of an existing endoscope. In the prior art, the lens of an endoscope is usually turned by controlling the serpentine frame with four traction ropes. Chinese Utility Model Patent: Publication (Announcement) No. CN209705602U, discloses "An Endoscope," whose description states that "the endoscope also includes a turning device 5, which includes: a universal ball 51, a rocker arm 52, and multiple traction ropes 53; the universal ball 51 is rotatably mounted inside the display host 1, and the rocker arm 52 is mounted on the universal ball 51 and partially protrudes from the display host." On the surface of the machine 1, one end of each traction rope 53 is equally spaced on the universal ball 51 and passes through the insertion tube 4 and the steering joint 6 so that the other end is placed on the probe 2. The bending direction of the steering joint 6 can be controlled by the rocker arm 52, the universal ball 51 and the traction rope 53, so that the probe 2 can bend and detect 360°, which has the advantage of a wide detection field. In addition, the rocker arm 52 is set by lever principle, so the heavy probe 2 can be turned by only a small force of the finger, thus also having the advantages of convenient operation and labor saving.

[0003] However, the limiting mechanism of this steering structure usually relies on the tightness of the housing. In actual use, if the housing structure becomes loose, it will affect the normal operation of the steering device, leading to a decrease in the steering accuracy of the probe, or even errors, thus affecting the endoscope's detection effect. Therefore, we have made improvements and proposed a four-way adjustable endoscope. Utility Model Content

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background art, existing steering structure limits usually rely on the tightness of the housing. In actual use, if the housing structure becomes loose, it will affect the normal operation of the steering device, causing the steering accuracy of the probe to decrease or even produce errors, thereby affecting the detection effect of the endoscope.

[0030] To solve this technical problem, this utility model provides a four-way adjustable endoscope.

[0031] For details, please refer to Figures 1-5 The four-way adjustable endoscope specifically includes:

[0032] The shell structure includes a steering mechanism 2. The steering mechanism 2 includes a hemispherical shell 209. A second connecting rod 208 is connected inside the hemispherical shell 209. Two second connecting seats 207 are provided at one end of the second connecting rod 208. A cross connector is provided between the two second connecting seats 207. The cross connector connects two first connecting seats 203. A first connecting rod 202 is connected between the two first connecting seats 203. A mounting plate 201 is fixedly connected to one end of the first connecting rod 202. The mounting plate 201 is installed inside the shell structure.

[0033] The four-way adjustable endoscope provided by this utility model achieves the limitation of the hemispherical shell 209 and the operating handle 210 in four directions through the setting of the first connecting rod 202, the first connecting seat 203, the cross connector, the second connecting seat 207 and the second connecting rod 208. The looseness between the first shell 1 and the second shell 101 does not affect the turning of the hemispherical shell 209 and the operating handle 210, which enhances the stability during turning and ensures the detection effect of the endoscope.

[0034] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] For an example, please refer to... Figures 1-5A four-way adjustable endoscope includes a housing structure. A steering mechanism 2 is installed within the housing structure. The steering mechanism 2 includes a hemispherical shell 209. A second connecting rod 208 is connected inside the hemispherical shell 209. Two second connecting seats 207 are provided at one end of the second connecting rod 208. A cross connector is provided between the two second connecting seats 207. The cross connector connects to two first connecting seats 203. A first connecting rod 202 is connected between the two first connecting seats 203. A mounting plate 201 is fixedly connected to one end of the first connecting rod 202. The mounting plate 201 is installed inside the housing structure. This application achieves four-way adjustment of the hemispherical shell 209 and the operating handle 210 through the first connecting rod 202, first connecting seats 203, cross connector, second connecting seats 207, and second connecting rod 208. Loosening between the first housing 1 and the second housing 101 does not affect the steering of the hemispherical shell 209 and the operating handle 210, enhancing stability during steering and ensuring the endoscope's detection effect.

[0038] Furthermore, such as Figures 1-2 As shown, the housing structure includes a first housing 1 and a second housing 101. A connecting nozzle 102 is provided on the second housing 101. The steering mechanism 2 is located inside the second housing 101 and the connecting nozzle 102. The first housing 1 and the second housing 101 together form a closed space, which effectively resists external environmental interference and significantly extends the service life of the steering mechanism 2.

[0039] Furthermore, the mounting plate 201 is installed inside the second housing 101, and the mounting plate 201 is connected to the second housing 101 by bolts. The mounting plate 201 provides a stable support base for the steering mechanism 2.

[0040] Furthermore, such as Figures 3-5 As shown, the cross connector includes an adapter 204 located between two first connecting seats 203 and two second connecting seats 207. A first connecting shaft 205 is connected between the adapter 204 and the two first connecting seats 203, and a second connecting shaft 206 is connected between the adapter 204 and the two second connecting seats 207. Through the cooperation of the adapter 204, the first connecting shaft 205, the second connecting shaft 206, the second connecting seat 207, and the first connecting seat 203, the connection between the first connecting rod 202 and the second connecting rod 208 can be realized. Through the coordinated work of the multiple components of the cross connector, the first connecting rod 202 and the second connecting rod 208 can rotate precisely relative to each other, driving the hemispherical shell 209 and the operating handle 210 to achieve four-way adjustment, enabling the endoscope to successfully complete the detection task in complex environments.

[0041] Furthermore, such as Figures 4-5As shown, the first connecting shaft 205 and the second connecting shaft 206 are arranged perpendicularly to each other, so that the second connecting rod 208 can rotate independently around these two shafts in two mutually perpendicular planes, corresponding to the adjustment in the up and down direction and the left and right direction respectively, thus realizing the four-way adjustment function in an orderly manner.

[0042] Furthermore, the second connecting rod 208 rotates around the second connecting shaft 206 to adjust in the vertical direction, and the second connecting rod 208 rotates around the first connecting shaft 205 to adjust in the horizontal direction, so as to achieve four-way adjustment.

[0043] Furthermore, such as Figure 3 As shown, the hemispherical shell 209 is connected to four traction rope bodies 3. One end of each of the four traction rope bodies 3 passes through the mounting plate 201 and extends into the connecting nozzle 102. The traction rope bodies 3 are used to connect with the snake bone at the end of the lens.

[0044] Furthermore, the mounting plate 201 is provided with perforations that match the traction rope body 3. The traction rope body 3 passes through the perforations, and the perforations provide precise guidance for the movement of the traction rope body 3. During the movement of the traction rope body 3, the perforations can effectively prevent problems such as entanglement or deviation.

[0045] Furthermore, such as Figure 1 As shown, the first housing 1 is provided with a through port, and the outer surface of the hemispherical shell 209 is inserted into the through port, which provides operating space for the movement of the operating handle 210.

[0046] Furthermore, such as Figure 1 and Figure 3 As shown, an operating handle 210 is fixedly connected to the side of the hemispherical shell 209 away from the mounting plate 201. One end of the operating handle 210 extends to the outside of the first housing 1 through a through hole to facilitate operation of the operating handle 210.

[0047] It should be noted that the technical solution of this application is only for the structural innovation of the endoscope turning mechanism 2. Other conventional components (such as the lens end and connecting tube) all use existing mature technologies without improvement. Therefore, the specification and drawings are not shown in detail. Those skilled in the art should understand that the conventional structural features of the unshown parts should not be regarded as insufficient disclosure of this application.
