[0001] The present application relates to the technical field of medical devices, in particular to a manipulation assembly of an endoscope and an endoscope. BACKGROUND

[0002] An endoscope is a commonly used medical device. When in use, the endoscope enters the patient's body through a natural orifice or a surgically formed incision, and reaches the organ to be detected, so that the doctor can directly observe the lesion of the relevant part.

[0003] The endoscope is currently divided into a hard endoscope and a soft endoscope. The soft endoscope in the prior art generally comprises a tip assembly, a bending portion, an insertion portion and a manipulation assembly connected in sequence. The manipulation assembly comprises a shell, a winding wheel located in the shell, a manipulation portion provided on the shell, etc. A traction line is wound on the winding wheel, and the traction line is connected with the distal end of the bending portion. The manipulation portion is coaxially connected with the winding wheel, and the winding wheel is driven to rotate by rotating the manipulation portion, so that the bending portion can be bent, and the tip assembly can be adjusted in angle.

[0004] However, the traction line wound on the winding wheel often becomes loose, which causes that the tip assembly inserted into the human body cannot be effectively controlled to reach a specified angle or a predetermined position when the endoscope is in use, so that the operation reliability of the endoscope is poor.

[0016] The surface of the extension main body facing the elastic arm is provided with a clamping arm, the clamping arm extends into the interval between the elastic arm and the outer circumference of the rotating main body, and is clamped to the rotating main body.

[0017] In one of the embodiments, the number of winding wheel pieces is two.

[0018] One end of the rotating main body is provided with a rotating shaft, and the sleeve joint parts of the two winding wheel pieces are sleeved on the rotating shaft.

[0022] The winding wheel rotates relative to the housing between the first limit position and the second limit position.

[0023] Two positioning parts are arranged on the positioning member.

[0024] When the winding wheel is located at the first limit position, it abuts against one of the positioning parts, and when the winding wheel is located at the second limit position, it abuts against the other positioning part.

[0049] The endoscope operating assembly and the endoscope of the embodiments of the present application will be described below with reference to the accompanying drawings.

[0050] Fig. 1 is a structural schematic diagram of the endoscope operating assembly provided by the embodiments of the present application; Fig. 2 is a sectional view of the endoscope operating assembly provided by the embodiments of the present application; Fig. 3 is a structural schematic diagram of the endoscope operating assembly provided by the embodiments of the present application from another angle; Fig. 4 is an exploded structural schematic diagram of the winding wheel in the endoscope operating assembly provided by the embodiments of the present application.

[0051] Referring to Figs. 1-4, the endoscope operating assembly 100 provided by the embodiments of the present application includes a housing 10, a winding wheel 20 and at least one traction line 40.

[0052] The winding wheel 20 includes a base 30 and at least one winding wheel piece 50 connected to the base 30, and the base 30 is rotationally connected to the housing 10 around a first axis.

[0053] At least one traction line 40 is connected with the winding wheel piece 50 one by one, and is used to be connected with the bending part (not shown) of the endoscope. The traction line 40 is used to control the bending of the bending part when the base 30 drives the winding wheel piece 50 to rotate.

[0054] The winding wheel piece 50 can rotate relative to the base 30 around the first axis O. The first limiting part 51 is arranged on the winding wheel piece 50, and the second limiting part 32 is arranged on the base 30. The first limiting part 51 and the second limiting part 32 are matched with each other to lock the winding wheel piece 50 relative to the base 30 at different locking positions when the winding wheel piece 50 is adjusted to rotate relative to the base 30.

[0055] The winding wheel piece 50 is connected to the base 30, and the traction line 40 is connected to the winding wheel piece 50 and the bending part of the endoscope. Therefore, when the base 30 rotates relative to the shell 10 to drive the winding wheel piece 50 to rotate, the traction line 40 can be driven to act to control the bending action of the bending part.

[0056] The first limiting part 51 and the second limiting part 32 are arranged on the winding wheel piece 50 and the base 30 respectively, and are matched with each other to lock the winding wheel piece 50 relative to the base 30 at different locking positions when the winding wheel piece 50 is adjusted to rotate relative to the base 30. In this way, when the winding wheel piece 50 rotates relative to the base 30, the traction line 40 connected to the winding wheel piece 50 is adjusted in the direction of tension or relaxation. Then, through the cooperation of the first limiting part 51 and the second limiting part 32, the winding wheel piece 50 is locked at a certain locking position relative to the base 30 after rotation. In this way, during the adjustment process, only the winding wheel piece 50 needs to be rotated according to the actual demand. Through the cooperation of the first limiting part 51 and the second limiting part 32, the winding wheel 20 can adjust the tension degree of the traction line 40 through simple operation without disassembling the winding wheel 20. When the traction line 40 is relaxed, the above process is adjusted. The winding wheel 20 can effectively control the tip end inserted into the human body to reach a specified angle or a predetermined position, so that the operation reliability of the endoscope is high.

[0057] In the embodiment of the application, with reference to FIGS. 3 and 4, the first limiting part 51 and the second limiting part 32 are both configured as meshing teeth that can mesh with each other.

[0058] The winding wheel piece 50 includes a sleeve joint part 52 and a winding part 53 connected with each other. The sleeve joint part 52 is rotationally connected to the base 30, and the winding part 53 is partially arranged on the circumferential outer side of the base 30. The first limiting part 51 and the second limiting part 32 are respectively arranged on the surfaces of the winding part 53 and the base 30 facing each other.

[0059] In this way, the first limiting part 51 and the second limiting part 32 face each other and can be locked by engaging with each other.

[0060] In the embodiment, the engaging teeth on the first limiting part 51 are first engaging teeth 311, the engaging teeth on the second limiting part 32 are second engaging teeth 312, the interval between adjacent first engaging teeth 311 is smaller than the interval between adjacent second engaging teeth 312, so that at least two first engaging teeth 311 can be inserted between two adjacent second engaging teeth 312.

[0061] For example, two first engaging teeth 311 can be inserted between two adjacent second engaging teeth 312, which can improve the engagement strength. Of course, the engagement surface 3120 between the first engaging teeth 311 and the second engaging teeth 312 needs to be inclined to the tension direction of the traction line 40, so that after the winding wheel 50 is adjusted to rotate relative to the base 30 in the direction of tensioning the traction line 40, the first engaging teeth 311 and the second engaging teeth 312 will not be separated or withdrawn from each other, thereby playing a role in preventing retreat.

[0062] In addition, the setting range of the first engaging teeth 311 is also larger than that of the second engaging teeth 312, so that after the first limiting part 51 and the second limiting part 32 rotate relative to each other, the first engaging teeth 311 and the second engaging teeth 312 can still be engaged. The setting range and number of the first engaging teeth 311 and the second engaging teeth 312 can be flexibly adjusted according to actual needs.

[0063] In the embodiment, continuing to refer to FIGS. 3 and 4, the base 30 includes a rotating main body 33 and an elastic arm 34 connected to the outer circumferential side of the rotating main body 33, the elastic arm 34 can be elastically deformed along the radial inner side of the rotating main body 33, and the second limiting part 32 is arranged on the surface of the elastic arm 34 away from the rotating main body 33.

[0064] In this way, when the winding wheel 50 rotates relative to the base 30, the first limiting part 51 presses against the second limiting part 32, so that the elastic arm 34 is pressed and elastically deformed towards the radial inner side of the rotating main body 33, and the second limiting part 32 can be avoided to the radial inner side, so as not to interfere with the first limiting part 51, that is, not to affect the rotation of the winding wheel 50. After the winding wheel 50 rotates to the target position, the elastic arm 34 elastically returns to the initial position, and the second limiting part 32 engages into the first limiting part 51 along the radial direction outward.

[0065] In the embodiment, the winding part 53 includes an extension main body 531 and a flange part 532, two ends of the extension main body 531 are connected to the sleeve part 52 and the flange part 532 respectively, and the extension main body 531 is located on one side of the axial direction of the rotating main body 33, and the flange part 532 is arranged on the outer circumferential side of the elastic arm 34.

[0066] The surface of the extension body 531 facing the elastic arm 34 is provided with a clamping arm 5310, which extends into the space between the elastic arm 34 and the outer periphery of the rotating body 33 and is clamped to the rotating body 33.

[0067] In this way, through the clamping of the clamping arm 5310 and the rotating body 33, the winding wheel piece 50 can be fixed in the axial direction of the rotating body 33, while the rotating connection of the two is not affected.

[0068] Of course, the space between the elastic arm 34 and the outer periphery of the rotating body 33 extends around the circumference of the rotating body 33, and the extension length is greater than the width of the clamping arm 5310 in the circumference, so as to avoid interference with the rotation of the clamping arm 5310.

[0069] In specific implementation, the elastic arm 34 can be formed of an elastic material and form a long strip-shaped annular structure, which includes two opposite long edges, one of which is connected to the outer side of the rotating body 33 in the circumferential direction, and the other is arranged in the radial direction outside the rotating body 33. The second limiting portion 32 is arranged on the outer side of the other long edge. In this way, when the engagement teeth on the first limiting portion 51 and the engagement teeth on the second limiting portion 32 are engaged with each other or disengaged, the elastic arm 34 can be elastically deformed in the radial direction of the rotating body 33 through the deformation of the annular structure. Of course, when the clamping arm 5310 is inserted into the annular structure, the annular structure can limit the rotation of the clamping arm 5310 when the clamping arm 5310 rotates in the circumferential direction of the rotating body 33, that is, when the clamping arm 5310 rotates to a certain extent, it is blocked and limited by the short edge of the annular structure, and cannot continue to rotate.

[0070] In addition, the number of clamping arms 5310 can be set as needed, for example, each extension body 531 can be provided with two clamping arms 5310, which can be arranged in the circumferential direction of the rotating body 33, and the end of each clamping arm 5310 can also be provided with a hook-shaped structure. When the clamping arm 5310 is inserted into the annular structure of the elastic arm 34, the hook-shaped structure can be matched with one end face of the rotating body 33.

[0071] In the embodiment of the application, the number of winding wheel pieces 50 is two.

[0072] One end of the rotating body 33 is provided with a rotating shaft 331, and the sleeve connection portions 52 of the two winding wheel pieces 50 are sleeved on the rotating shaft 331.

[0073] The sleeve connection portions 52 of the two winding wheel pieces 50 are staggered in the axial direction of the rotating shaft 331, and the winding portions 53 of the two winding wheel pieces 50 are staggered in the circumferential direction of the rotating shaft 331.

[0074] In this way, the bending control of the bending portion in two directions can be realized by the two traction lines 40.

[0075] Of course, the two winding portions 53 can or can not contact each other in the circumferential direction of the rotating shaft 331.

[0076] In the embodiment of the present application, referring to FIG. 1 and FIG. 4, the winding portions 53 of the two winding wheels 50 are aligned with each other in the axial direction of the rotating shaft 331, i.e., the setting heights of the winding portions 53 of the two winding wheels 50 are the same.

[0077] In this way, the appearance can be improved, and the adjustment operation is more convenient. Since the two sleeve portions 52 are staggered with each other in the axial direction of the rotating shaft 331 and are stacked together along the axial direction (the setting positions are offset by a certain amount along the axial direction), in order to make the winding portions 53 flush in the axial direction, the winding portion 53 in one of the winding wheels 50 (e.g., the winding wheel 50 located at the upper right corner in FIG. 4) and the sleeve portion 52 need to be staggered by a certain distance in the axial direction, i.e., the winding wheel 50 located at the upper right corner in FIG. 4 is offset by a certain distance to the left and down relative to the sleeve portion 52 along the axial direction.

[0078] In the embodiment of the present application, the operating assembly 100 further comprises a positioning member (not shown) connected in the housing 10, and the winding wheel 20 is located between the positioning member and the housing 10.

[0079] The winding wheel 20 rotates relative to the housing 10 between the first limit position and the second limit position, and the positioning member is provided with two positioning portions, the winding wheel 20 abuts against one of the positioning portions when located at the first limit position, and abuts against the other positioning portion when located at the second limit position. In this way, the rotation of the winding wheel 20 relative to the housing 10 can be limited within a certain range.

[0080] In the embodiment of the present application, as shown in FIG. 2, the operating assembly 100 further comprises an operating portion 60, one end of the operating portion 60 extends into the housing 10 and is connected with the base 30, and the operating portion 60 is used to drive the winding wheel 20 to rotate.

[0081] In specific implementation, the housing 10 is provided with a through hole, and part of the structure of the operating portion 60 passes through the through hole and enters the housing 10, and the winding wheel 20 and the operating portion 60 can be fixedly connected by a fastener 61, such as a screw. The part of the operating portion 60 for manual operation is located outside the housing 10. Of course, the operating portion 60 can be locked at the required position by a locking or damping member after rotation, which will not be described here.

[0082] The application further provides an endoscope comprising the above-mentioned steering assembly 100. The structure, function and working principle of the steering assembly have been described in detail above, and thus will not be described again.

[0083] The technical features of the above-mentioned embodiments can be combined in any manner. In order to make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described herein, but as long as the combinations of the technical features do not exist in contradiction, they shall be considered as falling within the scope of the present disclosure.

[0084] The above-mentioned embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It should be pointed out that, for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these shall fall within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
