Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment and do not mean that the composition and / or sequence are necessary.

[0037] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0038] Some embodiments of the endoscope handle and endoscope assembly of the present application are provided below with reference to the accompanying drawings. The endoscope handle and the endoscope catheter can be assembled in combination to form an endoscope assembly, so that the two ends of the handle traction member of the endoscope handle are respectively connected to the two ends of the bending traction rope of the endoscope catheter, so that when in use, the second rotating member and the first rotating member of the rotating operation assembly are used to drive the handle traction member to rotate, and then the bending part of the endoscope catheter is pulled to bend by the traction force of the bending traction rope to change the position and orientation of the endoscope module. Among them, by setting the handle traction member to pass through the multiple fixed wire groove structures on the first rotating member, and fixedly connected to the first rotating member at the same time, the connection between the handle traction member and the first rotating member is made more secure to prevent loosening or falling off.

[0039] Please refer to Figure 1 and Figure 2 In the embodiment of the first aspect of the present application, an endoscope handle 100 is provided, comprising a shell 1 and a rotating operation component 2, which can be used in conjunction with an endoscope catheter 400, and an insertion tube 430 of the endoscope catheter 400 is assembled in the shell 1 of the endoscope handle 100 and connected to an interface component 131 installed on the shell 1; two bent traction ropes 421 of the bent portion 420 of the endoscope catheter 400 can extend into the shell 1.

[0040] like Figure 1 and Figure 2 As shown, the housing 1 of the endoscope handle 100 is provided with a first mounting hole 11, and the endoscope catheter 400 is installed in the first mounting hole 11 when in use. The rotation operation assembly 2 includes a first rotating member 21, a handle pulling member 22, and a second rotating member 23; the first rotating member 21 and the handle pulling member 22 are both arranged in the housing 1, and the second rotating member 23 is arranged outside the housing 1; the first rotating member 21 is rotatably connected to the housing 1, and the second rotating member 23 is fixedly connected to the first rotating member 21, and specifically, part of the structure of the second rotating member 23 can penetrate into the housing 1, or part of the structure of the first rotating member 21 can penetrate out of the housing 1. Among them, a plurality of fixed wire groove structures 211 are arranged on the first rotating member 21, and the handle traction member 22 is inserted into the plurality of fixed wire groove structures 211 and fixedly connected to the first rotating member 21; the handle traction member 22 has a first end 221 and a second end 222 which are arranged opposite to each other. When the endoscope handle 100 is assembled with the endoscope catheter 400, the first end 221 of the handle traction member 22 is connected to a bent traction rope 421 of the endoscope catheter 400, and the second end 222 is connected to another bent traction rope 421 of the endoscope catheter 400.

[0041] When in use, the user can hold the housing 1 of the endoscope handle 100, and rotate the second rotating member 23 of the rotating operating assembly 2 to drive the first rotating member 21 to rotate relative to the housing 1, and then use the handle traction member 22 fixedly connected to the first rotating member 21 to pull a bending traction rope 421 of the endoscope catheter 400 to tighten it, so that the bending portion 420 of the endoscope catheter 400 is bent in the corresponding direction of the tightened bending traction rope 421. For example, when the two bending traction ropes 421 are respectively arranged on the upper and lower sides of the bending portion 420, the upper bending traction rope 421 can be pulled and tightened by the second end 222 of the handle traction member 22, so that the bending portion 420 of the endoscope catheter 400 is bent upward (such as Figure 1 On the contrary, by pulling the bent traction rope 421 issued downward by the first end 221 of the handle traction member 22 to tighten, the curved portion 420 of the endoscope catheter 400 is bent downward (as shown in the state of the dotted line above the curved portion 420); Figure 1 The state shown by the dotted line below the middle bending portion 420).

[0042] Since the handle pulling member 22 needs to be inserted into the multiple wire fixing groove structures 211 on the first rotating member 21, and the handle pulling member 22 is also fixedly connected to the first rotating member 21, the multiple wire fixing groove structures 211 can be arranged in a certain manner as needed, and the handle pulling member 22 can be inserted into the multiple wire fixing groove structures 211 in sequence in a preset order, so that the connection between the handle pulling member 22 and the first rotating member 21 is more secure.

[0043] It is understood that in practical applications, the bending direction of the bending portion 420 of the endoscope catheter 400 can be set according to the use requirements, and is not limited to Figure 1 For example, two bending traction ropes 421 of the bending portion 420 may be provided, respectively located on the left and right sides of the bending portion 420, so that the bending portion 420 can be driven to bend to the left or right by tightening the bending traction ropes 421.

[0044] The endoscope handle 100 in this embodiment is provided with a plurality of fixed wire groove structures 211 on the first rotating member 21, and the handle pulling member 22 is passed through the plurality of fixed wire groove structures 211 and fixedly connected to the first rotating member 21, so that the connection between the handle pulling member 22 and the first rotating member 21 is more secure, and can effectively prevent the handle pulling member 22 from sliding, loosening, etc., so as to effectively ensure the operation control accuracy of the endoscope handle 100 when used in conjunction with the endoscope catheter 400, prevent affecting normal surgery or diagnostic operations, and increase product reliability.

[0045] It should be noted that the appearance of the housing 1 in this embodiment is not limited to Figure 1 and Figure 2 The examples in the figure can be set to corresponding shapes according to the user's needs, so that the user can hold and operate them easily.

[0046] In further embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3 On the first rotating member 21, the wire fixing groove structure 211 includes a first wire fixing groove 2111 and a second wire fixing groove 2112. The first rotating member 21 is provided with a first wire fixing groove 2111 on the outer side thereof in the circumferential direction, and the first wire fixing groove 2111 extends along the circumferential direction of the first rotating member 21; a plurality of wire fixing protrusion structures 212 are provided on one side of the first rotating member 21, and each wire fixing protrusion structure 212 is provided with a second wire fixing groove 2112, for example Figure 2 and Figure 3 The side wall of the wire fixing protrusion structure 212 shown in the figure is provided with a second wire fixing groove 2112 on the side away from the first rotating member 21. The handle traction member 22 is specifically a flexible structure, such as a steel wire rope or a similar flexible rope body. The first part of the handle traction member 22 is wound in the first wire fixing groove 2111 along the circumference of the first rotating member 21, and the second part of the handle traction member 22 is passed through a plurality of second wire fixing grooves 2112. At the same time, the handle traction member 22 is also bonded and fixed to the wire fixing protrusion structure 212.

[0047] When the first rotating member 21 rotates relative to the housing 1, the handle traction member 22 rotates accordingly with the first rotating member 21, so that the first end 221 or the second end 222 of the handle traction member 22 is tightened. Figure 2 For example, when the first end 221 of the handle traction member 22 is tightened, the second end 222 is loosened, and accordingly, the bending traction rope 421 above the endoscope catheter 400 is tightened, and the bending traction rope 421 below is loosened, so that the bending portion 420 of the endoscope catheter 400 is bent upward; conversely, when the second end 222 of the handle traction member 22 is tightened, the first end 221 is loosened, and accordingly, the bending traction rope 421 below the endoscope catheter 400 is tightened, and the bending traction rope 421 above is loosened, so that the bending portion 420 of the endoscope catheter 400 is bent downward. By operating the second rotating member 23 to rotate clockwise or counterclockwise, the bending portion 420 of the endoscope catheter 400 can be driven to bend in two opposite directions.

[0048] It should be noted that, in practical applications, the number of the wire fixing protrusion structures 212 is not limited to Figure 2 and Figure 3 The four shown in the figure may also be provided in other numbers; the second fixing groove 2112 is not limited to Figure 2 and Figure 3The straight groove structure shown in the figure can also be set as a curved groove structure; the setting position of the second fixing groove 2112 is not limited to the end surface of the fixing protrusion structure 212, and can also be set on the side wall of the fixing protrusion structure 212.

[0049] In addition, the plurality of wire fixing protrusion structures 212 may be arranged in rows and columns, and the plurality of second wire fixing grooves 2112 may be arranged in rows and columns. Figure 2 and Figure 3 The parallel arrangement shown in the figure can also be arranged to form a preset angle with each other as needed; the order in which the handle traction member 22 passes through the plurality of second fixing grooves 2112 is not limited to the following. Figure 2 and Figure 3 The sequence shown in FIG. 1 may also be used to pass through multiple second wire fixing grooves 2112 in a cross manner, which will not be repeated here.

[0050] In a further embodiment of the present application, Figure 2 and Figure 3 As shown, a first groove 213 is provided on one side of the first rotating member 21 provided with a wire fixing protrusion structure 212, and a plurality of wire fixing protrusion structures 212 are all located in the first groove 213; the first wire fixing groove 2111 is located on the outer side wall of the first groove 213, and a first notch 214 penetrating the first wire fixing groove 2111 is provided on the side wall of the first groove 213, for example Figure 2 The first groove 213 shown in the figure is provided with a first notch 214 on one side away from the first mounting hole 11, the second part of the handle traction member 22 is located in the first groove 213, the first part passes through the first notch 214, and the part connected to the first end 221 and the part connected to the second end 222 are respectively arranged in the first wire fixing groove 2111 along both sides of the first notch 214. The first groove 213 is filled with colloid, and the colloid covers the multiple wire fixing protrusion structures 212 in the first groove 213 and the second part of the handle traction member 22, so that the handle traction member 22 and the first rotating member 21 are bonded as a whole, and the connection strength is higher.

[0051] In a further embodiment of the present application, Figure 2 and Figure 3As shown, the rotating operation assembly 2 also includes a rotating base 24. The rotating base 24 is fixedly connected to the housing 1 to facilitate the installation of the first rotating member 21. Specifically, the rotating base 24 is arranged between the first rotating member 21 and the housing 1, and a second groove 241 is provided on the side of the rotating base 24 facing the first rotating member 21, and a bearing 242 and a rotating limit block 245 are arranged in the second groove 241; the first rotating member 21 is located in the second groove 241 and is connected to the bearing 242. The first rotating member 21 is rotatably connected with the rotating base 24 and the housing 1 through the bearing 242, and can rotate relative to the rotating base 24 and the housing 1. The rotation limit block 245 cooperates with the bearing 242 to limit the rotation stroke of the bearing 242 and the first rotating member 21, so that the first rotating member 21 can only rotate within a preset angle range, and the angle range is adapted to the size of the bending traction rope 421 of the endoscopic catheter 400 to prevent the first rotating member 21 from rotating too much and causing the bending traction rope 421 to break.

[0052] The inner side wall of the second groove 241 is opposite to the opening side of the first wire fixing groove 2111 on the outer side wall of the first rotating member 21, so that the inner side wall of the second groove 241 and the first wire fixing groove 2111 are enclosed to form a laterally nearly closed wire passing channel; a second notch 243 is provided on the side wall of the second groove 241 opposite to the first notch 214, that is, the second notch 243 passes through the wire passing channel, and the first end 221 and the second end 222 of the handle traction member 22 are both passed through the second notch 243, so as to be connected with the bent traction rope 421 of the endoscope catheter 400. By providing the second groove 241 and the second notch 243, the formed wire passing channel can be used to form a lateral limit on the handle traction member 22 to prevent the handle traction member 22 from falling off from the first wire fixing groove 2111, and at the same time, the second notch 243 can also play a certain guiding and tensioning role on the handle traction member 22.

[0053] In a further embodiment, Figure 3 In the example shown in FIG. 1 , the rotating base 24 and the shell 1 are integrally formed, which is beneficial to simplifying the processing process and reducing the connection structure.

[0054] In a further embodiment, Figure 2 and Figure 3In the example in FIG. 1 , the first rotating member 21, the first groove 213 and the second groove 241 are all circular structures to match the rotation operation of the first rotating member 21, and can also save space, so as to facilitate the arrangement of various components in the limited space in the housing 1. An arc region 12 is provided on the housing 1 at a position corresponding to the radial outer side of the first rotating member 21. Accordingly, one end of the second rotating member 23 passes through the side wall of the housing 1 and the rotating base 24, and is fixedly connected to the first rotating member 21. The other end of the second rotating member 23 extends from the side of the housing 1 to the radial outer side of the arc region 12, so as to facilitate the rotation operation of the second rotating member 23. The arc region 12 can match the rotation path of the second rotating member 23 to prevent mutual interference.

[0055] For example, Figure 3 In the example, a central hole 164 can be opened on the housing 1, and the first rotating member 21, the first groove 213, the rotating base 24, and the second groove 241 are all coaxially arranged with the central hole 164. The first rotating member 21 is provided with an assembly hole coaxial with the central hole 164, and one end of the second rotating member 23 passing through the central hole 164 is provided with a corresponding bolt hole. When assembling, the first rotating member 21 and the second rotating member 23 are connected and fixed by bolts. Of course, the above is only one of the connection methods between the first rotating member 21 and the second rotating member 23. In actual application, other connection methods can also be used according to assembly needs.

[0056] In a further embodiment, Figure 2 and Figure 3 As shown, the rotating operation assembly 2 further includes a support plate 251 and a guide spring 252. The number of the support plates 251 is one or more, and the support plates 251 are arranged in the housing 1 and are located between the first rotating member 21 and the second mounting hole 13, that is, located on the extension path of the handle traction member 22; two guide springs 252 are fixedly connected to the support plate 251, and the first end 221 and the second end 222 of the handle traction member 22 respectively pass through one of the guide springs 252, so that the guide spring 252 plays a guiding and limiting role on the handle traction member 22, so that when the first rotating member 21 rotates, the handle traction member 22 can only move axially in the guide spring 252, and can only move radially in a smaller range within the guide spring 252, so as to prevent the handle traction member 22 from moving in a larger range and getting entangled or rubbed with other components in the housing 1. Since the guide spring 252 is elastic, it can bend and deform within a certain range under the force of the handle traction member 22, so that the handle traction member 22 and the guide spring 252 form a soft contact, and the friction resistance is smaller, which is conducive to reducing the wear of the handle traction member 22 and extending the service life. Of course, in actual applications, a hard tube body can also be used instead of the guide spring according to assembly requirements.

[0057] In a further embodiment, Figure 2 and Figure 3 As shown, the rotation operation assembly 2 also includes two groups of threaded locking members 253.
