[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0027] It should be noted that the following detailed descriptions are illustrative and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways, rotated 90 degrees or in other orientations, and the spatially relative descriptions used herein are interpreted accordingly.
[0029] like Figures 1 to 5 As shown, the operating handle of this embodiment includes: a handle housing assembly 10, an actuator assembly 20 and an operating assembly 30. The handle housing assembly 10 has a mounting through hole 11, an operating long hole 16 and a receiving space 12. The operating long hole 16 extends along the axial direction of the handle housing assembly 10 and passes through the receiving space 12 and the outside of the handle housing assembly 10. The mounting through hole 11 is located at the first end of the handle housing assembly 10 and passes through the receiving space 12 and the outside of the handle housing assembly 10. The actuator assembly 20 includes a translation structure 21 and a rotation structure 22. The translation structure 21 can be movably arranged in the receiving space 12, and the rotation structure 22 is rotatably connected to a side of the translation structure 21 away from the mounting through hole 11. The operating assembly 30 is arranged outside the handle housing assembly 10 and connected to the actuator assembly 20.
[0030] By applying the technical solution of this embodiment, the operating assembly 30 is operated to move along the operating slot 16, and the operating assembly 30 drives the actuator 20, so that the translation structure 21 first translates; the assembly 30 is continued to be operated, the translation structure 21 stops the translation, and the rotation structure 22 rotates, so that the translation and rotation of the actuator 20 can be achieved by operating only the operating assembly 30. The technical solution of this embodiment effectively solves the problem that the operating handle of the medical device in the prior art needs to operate multiple operating parts.
[0031] It should be noted that the operating assembly 30 drives the rotating structure 22 to drive the translation structure 21 to translate the first action, and the operating assembly 30 drives the rotating structure 22 to rotate the second action. In this embodiment, the operating assembly 30 is connected to the rotating structure 22, and the rotating structure 22 is connected to the translation structure 21.
[0032] Taking the application of the operating handle to the endoscope as an example, the endoscope rod passes through the installation through-hole and is connected to the translation structure 21. The endoscope rod and the translation structure 21 can be directly connected by threads or by fasteners such as screws. The traction rope of the endoscope is connected to the rotation structure 22. The translation of the translation structure 21 drives the endoscope rod to translate as a whole, the first movement of the translation structure 21 ends, and the rotation structure 22 rotates. The first end of the traction rope is connected to the rotation structure 22, and the second end of the traction rope is connected to the inner wall of the end of the endoscope rod away from the operating handle. Since the traction rope and the rotation structure 22 are in a taut state, the rotation of the rotation structure 22 applies a force to the traction rope, and the traction rope drives the end of the endoscope rod away from the operating handle to bend, thereby driving the endoscope to rotate a certain angle.
[0033] like Figures 2 to 5 As shown, in the technical solution of this embodiment, the rotating structure 22 includes a connecting portion 221, a rotating portion 222 and a first rotating shaft. The connecting portion 221 is at least partially located outside the handle housing assembly 10 and cooperates with the operating assembly 30. The connecting portion 221 passes through the operating long hole 16 and is rotatably connected to the rotating portion 222. The rotating portion 222 is rotatably connected to the translation structure 21 through the first rotating shaft. When the operating assembly 30 is pushed forward (in front of the operator in the use state), the operating assembly 30 drives the translation structure 21 to translate through the rotating structure 22. After the translation structure 21 translates to a predetermined distance, the rotating portion 222 rotates relative to the connecting portion 221 and the translation structure 21.
[0034] like Figures 2 to 5As shown, in the technical solution of this embodiment, the translation structure 21 includes a translation block 211, the translation block 211 has a mounting hole on one side close to the mounting through hole 11, the translation block 211 has a first pivot hole on one side away from the mounting through hole 11, the rotating portion 222 includes a rotating block 2221 and a connecting arm 2222, the first end of the connecting arm 2222 is connected to the rotating block 2221, the second end of the connecting arm 2222 has a second pivot hole, and the first rotating shaft is adapted to the first pivot hole and the second pivot hole. The mounting hole is used to cooperate with the outside. The rotating block 2221 is rotatably connected to the translation block 211 through the connecting arm 2222, so that when the pivot shaft is directly connected to the rotating block 2221, the rotating block 2221 will not interfere with the inner wall of the handle housing assembly 10. The connecting arm 2222 is located near the front of the rotating block 2221. The translation structure 21 also includes a spring clip, the first end of which is rotatably connected to the translation block 211, the second end of which is a free end, the second end of which has a protrusion facing the side of the handle housing assembly 10 (the side away from the translation block 211), and the inner wall surface of the handle housing assembly 10 has a spring clip groove. When the translation operation is completed and the rotation begins, the protrusion of the spring clip just matches the spring clip groove, which makes it easy for the operator to feel the connection between the two movements. In addition, a certain degree of movement restraint can be formed on the translation block 211. The protrusion of the spring clip and the spring clip groove are inclined surfaces or arc surfaces, so that the protrusion of the spring clip and the spring clip groove will not be stuck, and the spring clip can be a plate-like thin sheet.
[0035] It should be noted that the operating assembly 30 includes an operating cover, and the translation structure 21 includes a guide block 212. The surface of the operating cover away from the handle housing assembly 10 is a rough surface, and the side facing the handle housing assembly 10 has a groove, and the connecting portion 221 is located in the groove. The connecting portion has a slide groove, and the guide block includes a flat plate, a vertical plate and a bent plate. The front of the flat plate, the vertical plate and the bent plate forms a groove. The translation block 211 includes an arc block and a connecting block on both sides. The connecting block is connected between the two arc blocks, and the connecting block is located in the groove. The flat plate and the bent plate are connected to the connecting block by screws, and the two sides of the flat plate form a slide rail, and the slide rail is located in the slide groove. Before pushing the operating cover forward, there is a predetermined distance between the guide block and the connecting portion in the axial direction of the handle housing assembly 10, and the distance is between 1.5 mm and 6 mm. In this way, after the translation structure 21 moves to the right position, the relative movement between the connecting portion and the guide block can realize that the translation structure 21 no longer moves forward, and the rotating structure 22 rotates. Specifically, when the rotating block 2221 moves horizontally to the operating long hole 16, the inner wall of the handle housing assembly 10 no longer constrains the rotating block 2221. A portion of the rotating block 2221 protrudes out of the operating long hole 16 to rotate, and the protruding portion of the rotating block 2221 enters the groove of the operating cover, so that the operating cover blocks the rotating block 2221 without interfering with the rotating block 2221.
[0036] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the rotating part 222 also includes a driving arm 2223 and a second rotating shaft. The first end of the driving arm 2223 is connected to the rotating block 2221. The second end of the driving arm 2223 has a third pivot hole. The second rotating shaft is installed in the third pivot hole. In the plane perpendicular to the handle housing assembly 10, the second rotating shaft is closer to the operating assembly 30 than the first rotating shaft. The connecting part 221 applies a force to the second rotating shaft, and the rotating part 222 rotates with the first rotating shaft as the central axis, so that the rotating part 222 will be away from the lower part ( Figure 4 The movement of the lower part in the middle), that is, the rotating part 222 will not interfere with the handle housing assembly 10.
[0037] It should be noted that there are two situations in which the first end of the driving arm 2223 is connected to the rotating block 2221. The first end of the driving arm 2223 is directly connected to the rotating block 2221, or is indirectly connected. The indirect connection can be that the first end of the driving arm 2223 is connected to the connecting arm 2222. In this embodiment, the first end of the driving arm 2223 is connected to the connecting arm 2222, and the axis of the first rotating shaft and the axis of the second rotating shaft are on the same plane perpendicular to the axis of the handle housing assembly 10.
[0038] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, the connecting portion 221 includes a connecting block 2211 and a pivot connecting arm 2212. The connecting block 2211 is located outside the handle housing assembly 10. The first end of the pivot connecting arm 2212 is connected to the connecting block 2211. The pivot connecting arm 2212 passes through the operating slot 16. The second end of the pivot connecting arm 2212 has a mounting groove 2213. The opening of the mounting groove 2213 faces away from the operating assembly 30. The mounting groove 2213 is located outside the handle housing assembly 10. Figure 4 There is a certain distance between the upper and lower directions of the mounting groove 2213, so that the second rotating shaft is not easy to escape from the mounting groove 2213. Specifically, when the rotating portion 222 rotates, the connecting portion 221 pulls the second rotating shaft, the first rotating shaft does not move, and the second rotating shaft moves toward the front and the bottom at the same time, and the rotating portion 222 rotates with the first rotating shaft as the central axis. The pivoting connecting arm 2212 is bent in a direction away from the mounting through hole 11. Such a structure is compact, and there is no need to set the connecting arm 2222 longer to accommodate the connecting portion 221.
[0039] like Figure 4 and Figure 5As shown, in the technical solution of this embodiment, the rotating block 2221 is rod-shaped, the width of the rotating block 2221 is smaller than the width of the operating slot 16, and the wall surfaces at both ends of the rotating block 2221 are adapted to the wall surfaces of the handle housing assembly 10. In this embodiment, when the rotating block 2221 is in translation, the inner wall surface of the handle housing assembly 10 restrains the rotating block 2221. When the rotating block 2221 moves to a position corresponding to the operating slot 16, the handle housing assembly 10 cannot restrain the rotating block 2221, the operating assembly 30 continues to move forward, and the rotating block 2221 rotates. It should be noted that the adaptation here means that the surface curvature is the same, and the wall surfaces at both ends of the rotating block 2221 are in contact with or adjacent to the inner wall surface of the handle housing assembly 10.
[0040] like Figure 4 and Figure 5 As shown, in the technical solution of this embodiment, a traction part is also provided on the rotating block 2221, and the traction part and the driving arm 2223 are respectively located on both sides of the first rotating shaft. The traction part is provided to facilitate the installation of external components. For example, a traction rope is connected to the traction part, and the rotating block 2221 is Figure 4 The upper part of the block 2221 moves forward, and the Figure 4 The lower part of the endoscope moves backward, so that the traction rope pulls the endoscope rod to bend, that is, the endoscope rotates to a certain angle, which can be set to 15°, 30°, 45°, or even 60° according to needs.
[0041] like Figures 1 to 3 As shown, in the technical solution of the present embodiment, the handle housing assembly 10 includes a handle 13, a shell main rod 14 and a handle head 15 connected in sequence, the handle 13, the shell main rod 14 and the handle head 15 together form a receiving space 12, and the operating slot 16 is provided on the shell main rod 14. The handle housing assembly 10 includes a handle 13, a shell main rod 14 and a handle head 15 connected in sequence, and such a structure is easy to process, assemble, inspect and maintain. In the technical solution of the present embodiment, the handle 13 is connected to the shell main rod 14 by threads, and the shell main rod 14 is connected to the handle head 15 by threads. Taking the connection between the handle 13 and the shell main rod 14 as an example, when the handle 13 is unscrewed from the shell main rod 14, the connection of the traction rope can be replaced to meet the rotation of the external operating rod matched with the operating handle in different directions.
[0042] The present application also provides a medical device, which includes a device body and an operating handle matched with the device body, and the operating handle is the above-mentioned operating handle. The medical device of the present application can be an endoscope, a grasper, a surgical cutting knife, etc.
[0043] It should be noted that the device body includes a traction rope, and the traction rope is connected to the rotating block 2221. The traction rope can be one traction rope or multiple traction ropes. When the traction rope is multiple traction ropes, the multiple traction ropes can be set near the traction part in advance, and the multiple traction ropes can be marked. For example, the upper traction rope is the traction rope close to the side of the operating component 30, the lower traction rope is the traction rope away from the operating component 30, the left traction rope is the traction rope on the left side when in use, and the right traction rope is the traction rope on the right side when in use.
