Description

Technical Field

[0001] The present application belongs to the technical field related to medical devices, and in particular, relates to an endoscope operating part and an endoscope. Background Art

[0002] An endoscope is a tube equipped with a light, which can be inserted into the stomach through the mouth or other natural orifices. The endoscope operating unit controls the degree of curvature of the endoscope's curved portion through an angle wire, so that the endoscope can adapt to the inspection needs of different parts.

[0003] Among them, after the endoscope has been used for a period of time, the angle wire of the endoscope will age and fatigue, making it impossible to tighten the angle wire well, resulting in the angle of the bending part of the endoscope failing to reach the design value, thus affecting the clinical diagnosis and treatment. For example, in gastroscopy, an inverted mirror is used to observe the cardia. If the bending angle is not enough, the tip of the endoscope cannot be close to the cardia for observation, biopsy and treatment, which seriously affects the clinical diagnosis and treatment; or in bronchoscopes, insufficient angles make it difficult to reach the upper lobe. In response to the aging phenomenon of the angle wire in the above-mentioned endoscope, at present, once the angle wire of the endoscope ages, a professional after-sales engineer needs to disassemble the operating part of the endoscope for maintenance and debugging, such as replacing a new angle wire. However, the endoscope is a precision instrument. Once it is disassembled, it needs to be resealed and installed, which will reduce the overall airtightness of the endoscope. In addition, the process of tightening the angle wire requires professional after-sales engineers to handle it, which is limited in operation and costly. Summary of the invention

[0004] In view of this, it is necessary to provide an endoscope operating unit and an endoscope for solving the above-mentioned technical problems.

[0005] An endoscope operating unit, the endoscope operating unit comprising:

[0006] case;

[0007] A connecting rope, passing through the housing and used for connecting the curved portion of the endoscope;

[0008] An operating mechanism, mounted on the housing and connected to the connecting rope, and the operating mechanism can control the bending angle of the bending portion of the endoscope through the connecting rope;

[0009] The tightening mechanism is installed in the shell, and the tightening mechanism includes a driving member and a tightening assembly. The tightening assembly is transmission-connected with the driving member to move and tighten the connecting rope under the driving of the driving member.

[0010] It can be understood that the tightening component tightens the connecting rope under the drive of the driving member, so that the automatic tightening of the connecting rope can be achieved and it can be ensured that the connecting rope in the endoscope operating part is always in a tightened state to facilitate the operation of medical staff; at the same time, it can also avoid the maintenance and debugging of the endoscope operating part after disassembly, which can ensure the overall sealing of the endoscope using the endoscope operating part and play a role in reducing costs.

[0011] In one embodiment, the driving member is configured as an elastic member, and the elastic member is mounted on the housing in an energy storage state.

[0012] It is understandable that the driving member is set as an elastic member in an energy storage state. In this way, the structural characteristics of the elastic member can be used to drive the tightening assembly, which has the effect of simplifying the structure of the elastic member and reducing the cost of the elastic member.

[0013] In one embodiment, the tightening assembly includes an abutment member, the abutment member abuts against the connecting rope, and the abutment member can push the connecting rope under the driving of the driving member to tighten the connecting rope.

[0014] In one of the embodiments, the endoscope operating part further includes a first supporting member, which is disposed on a side of the abutting member facing the operating mechanism and abuts against the connecting rope, and is used to support the connecting rope in a tightened state.

[0015] It can be understood that the first support member is used to support the connecting rope in the tightened state. In this way, the stroke change of the connecting rope caused by the abutment member pushing the connecting rope can be increased, thereby improving the tightening effect of the connecting rope when the abutment member pushes the connecting rope.

[0016] In one embodiment, the endoscope operating part further includes a second supporting member, which is disposed on a side of the abutting member away from the first supporting member and abuts against the connecting rope for guiding the connecting rope.

[0017] It is understandable that the second support member is used to guide the connecting rope, so that the direction of the connecting rope can be guided and constrained, thereby preventing the connecting rope from interfering with the arrangement of other components in the endoscope operating part when being tightened.

[0018] In one embodiment, the number of the abutment members is two, the two abutment members are disposed on both sides of the tightening assembly, and the two abutment members move in opposite directions when driven by the driving member.

[0019] In one embodiment, the tightening assembly further includes a driving gear and two racks, wherein the driving gear is transmission-connected to the driving member and meshes with the two racks respectively;

[0020] The two racks correspond to the two abutting members one by one, and the abutting members are installed on the corresponding racks.

[0021] It can be understood that the abutment is driven to move by the meshing cooperation between the driving gear and the rack, so that the abutment can be infinitely adjusted under the drive of the rack, which ensures that the connecting rope is always in a tightened state under the pushing of the abutment.

[0022] In one embodiment, the tightening assembly further includes a transmission gear and a limiting unit, and the driving gear is transmission-connected to the driving member through the transmission gear;

[0023] The limiting unit is provided with a limiting convex portion, and the limiting convex portion can cooperate with the convex teeth on the transmission gear to control the unidirectional rotation of the transmission gear.

[0024] It is understandable that the limiting unit is used to control the one-way rotation of the transmission gear and the driving gear, so that the tightening component can be easily assembled into the endoscope operating part.

[0025] In one embodiment, the rack is marked with scale lines along the moving direction of the rack;

[0026] Wherein, a first viewing window is provided on the shell, and the scale line can be observed through the first viewing window.

[0027] It can be understood that the rack can drive the scale line to move relative to the first window, so that the real-time observation of the tightening degree of the connecting rope can be achieved, that is, the real-time grasp of the aging degree of the connecting rope can be achieved, so as to facilitate the subsequent inspection and maintenance of the endoscope operating part.

[0028] The present application also provides an endoscope, comprising an endoscope bending portion and the endoscope operating portion described above; the endoscope bending portion is transmission-connected to the connecting rope.

[0029] Due to the application of the above technical solution, the present application has the following advantages compared with the prior art:

[0030] The endoscope operating part and endoscope to be protected by the present application have a tightening component that tightens the connecting rope under the drive of a driving member. In this way, the connecting rope can be automatically tightened and the connecting rope in the endoscope operating part can be ensured to be in a tightened state at all times to facilitate operation by medical staff. At the same time, the maintenance and debugging of the endoscope operating part after disassembly can be avoided, which can ensure the overall sealing of the endoscope using the endoscope operating part and reduce costs.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0042] It should be noted that when an element is referred to as being "provided on" another element, it may be directly provided on the other element or there may be a central element. When an element is considered to be "provided on" another element, it may be directly provided on the other element or there may be a central element at the same time. When an element is considered to be "fixed to" another element, it may be directly fixed to the other element or there may be a central element at the same time.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0044] The endoscope operating unit 100 for which protection is sought in the present application is applied in an endoscope to control the bending angle of a bending portion (not shown) of the endoscope.

[0045] like Figure 1 , Figure 2 and Figure 6 As shown, an endoscope operating part 100 provided in an embodiment of the present application includes a housing 10, a connecting rope 20, an operating mechanism 30 and a tightening mechanism 40. The connecting rope 20 passes through the housing 10 and is used to connect the bending part of the endoscope. The operating mechanism 30 is installed on the housing 10 and connected to the connecting rope 20, and the operating mechanism 30 can control the bending angle of the bending part of the endoscope through the connecting rope 20. The tightening mechanism 40 is installed in the housing 10, and the tightening mechanism 40 includes a driving member 41 and a tightening assembly 42. The tightening assembly 42 is transmission-connected to the driving member 41 to move and tighten the connecting rope 20 under the driving of the driving member 41. In other words, the tightening assembly 42 can tighten the connecting rope 20 that is loosened due to aging in time under the driving of the driving member 41, so as to ensure that the connecting rope 20 is always in a tightened state in the operating part of the endoscope. Of course, the tightening assembly 42 is driven by the driving member 41 to move and tighten the connecting rope 20 . Specifically, the tightening assembly 42 is driven by the driving member 41 to tighten the connecting rope 20 .

[0046] It can be understood that the tightening assembly 42 tightens the connecting rope 20 under the drive of the driving member 41, so that the automatic tightening of the connecting rope 20 can be achieved, and the connecting rope 20 in the endoscope operating part 100 is ensured to be always in a tightened state, so as to facilitate the operation of medical staff; at the same time, it also avoids the maintenance and debugging of the endoscope operating part 100 after disassembly, so as to ensure the overall sealing of the endoscope with the endoscope operating part 100, and play a role in reducing costs. Of course, the endoscope operating part 100 of the present application can play a role in reducing costs, specifically, because there is no need for professional after-sales technicians to disassemble the endoscope operating part 100 for maintenance and debugging, which can reduce labor costs and improve the timeliness of maintenance.

[0047] It should be noted that how the above-mentioned connecting rope 20 is connected to the bending part of the endoscope, the specific structure of the operating mechanism 30 and how to control the bending angle of the bending part of the endoscope through the connecting rope 20 when the operating mechanism 30 is working can all adopt the conventional methods of existing endoscopes and will not be elaborated here.

[0048] In some embodiments, the connecting rope 20 is configured as an angle steel wire. Of course, for those skilled in the art, the connecting rope 20 can also be configured as a stainless steel wire, a tungsten wire, a copper wire, etc. according to needs.

[0049] like Figure 6 As shown, in some embodiments, the driving member 41 is configured as an elastic member 411, and the elastic member 411 is installed on the housing 10 in an energy storage state. In this way, the structural characteristics of the elastic member 411 can be used to automatically drive the tightening assembly 42, which has the effect of simplifying the structure of the elastic member 411 and reducing the cost of the elastic member 411. It should be noted that the elastic member 411 and the connecting rope 20 are transmitted and matched through the tightening assembly 42, that is, the elastic member 411 can drive the tightening assembly 42 and the connecting rope 20 to maintain a relatively stable state, so that once the connecting rope 20 is loosened due to aging, the elastic member 411 in the energy storage state can release a certain amount of energy and drive the tightening assembly 42 to tighten the connecting rope 20. Of course, the driving member 41 is not limited to the elastic member 411 in the energy storage state described above. For those skilled in the art, the driving member 41 can also be configured as a motor, and the motor is always in an on state, and the motor is in a stalled state under the reaction force of the tightening assembly 42, which will not be elaborated here.

[0050] Exemplarily, when the elastic member 411 drives the tightening assembly 42 to tighten the connecting rope 20 by providing a rotational driving force, the elastic member 411 can be set to a spring, a torsion spring, etc.; when the elastic member 411 drives the tightening assembly 42 to tighten the connecting rope 20 by providing a translational driving force, the elastic member 411 can be set to a spring, a tension spring, etc., which can be matched according to the specific structure of the tightening assembly 42 and the working principle of how the tightening assembly 42 tightens the connecting rope 20 when it is working, which will not be elaborated here.

[0051] like Figure 3-Figure 7 As shown, in some embodiments, the tightening assembly 42 includes an abutment member 421, which abuts against the connecting rope 20, and the abutment member 421 can push the connecting rope 20 under the driving of the driving member 41 to tighten the connecting rope 20. In other words, when the tightening assembly 42 of this embodiment is working, the abutment member 421 pushes the connecting rope 20 in one direction, and the connecting rope 20 is tightened by increasing the length required for the connecting rope 20 to pass through the abutment member 421 by using the principle that the line segment between two points is the shortest.

[0052] It should be noted that the outer dimensions of the housing 10 are fixed, so the tightening assembly 42 of this embodiment can tighten the connecting rope 20 by pushing the connecting rope 20 toward the center line direction of the endoscope operating part 100. In some embodiments, the connecting rope 20 can be pushed along the vertical direction when the connecting rope 20 passes through the abutment 421, so that the moving distance of the abutment 421 when pushing the connecting rope 20 can be maximized and converted into the travel change of the connecting rope 20, thereby improving the tightening effect of the abutment 421 when pushing the connecting rope 20.

[0053] Exemplarily, the abutment member 421 is configured as a guide wheel 4211, and the connecting rope 20 is disposed on the side of the guide wheel 4211 facing the center line direction of the endoscope operating unit 100 and abuts against the outer peripheral surface of the guide wheel 4211, so that the structure of the abutment member 421 can be simplified, and the assembly between the abutment member 421 and the connecting rope 20 can be facilitated. Of course, for those skilled in the art, the abutment member 421 can also be configured as a hook plate, a fixed block with a threading hole, etc., which will not be elaborated here.

[0054] like Figures 3 to 7 As shown, in some embodiments, there are two abutment members 421, which are arranged on both sides of the tightening assembly 42, and the two abutment members 421 move in opposite directions when driven by the driving member 41, so as to tighten the connecting rope 20 on the left and right sides of the center line of the endoscope operating part, and realize the tightening of the connecting rope 20 as a whole.

[0055] like Figure 3 , Figure 4 and Figure 7As shown, in some embodiments, the tightening assembly 42 further includes a driving gear 422 and two racks 423. The driving gear 422 is in transmission connection with the driving member 41 and meshes with the two racks 423 respectively; the two racks 423 correspond to the two abutting members 421 one by one, and the abutting members 421 are mounted on the corresponding racks 423. Under the drive of the driving member 41, the tightening assembly 42 can realize the driving of the two racks 423 to move toward each other by meshing with the driving gear 422 and the two racks 423, and realize the simultaneous pushing of the two abutting members 421 against the connecting rope 20, so as to achieve the purpose of tightening the connecting rope 20.

[0056] It can be understood that the above-mentioned tightening component 42 uses the meshing cooperation between the driving gear 422 and the rack 423 to realize power transmission. In this way, the abutment 421 can be infinitely adjusted under the drive of the rack 423, which can ensure that the connecting rope 20 is always in a tightened state under the pushing of the abutment 421.

[0057] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, in some embodiments, the tightening assembly 42 also includes a transmission gear 424, and the driving gear 422 is connected to the driving member 41 through the transmission gear 424. Specifically, the driving gear 422 can be fixedly connected to the transmission gear 424 in a coaxial manner, so that the transmission gear 424 can rotate together with the driving gear 422. To this end, the diameter of the driving gear 422 can be set smaller than the diameter of the transmission gear 424, so that sufficient installation space can be left for the rack 423, thereby reducing the installation space required for the tightening assembly 42 to be installed in the endoscope operating part 100, so as to facilitate the use of the tightening assembly 42 in the endoscope operating part 100.

[0058] like Figure 3 , Figure 4 , Figure 6-Figure 8 As shown, in some embodiments, the tightening assembly 42 further includes a limiting unit 425, on which a limiting convex portion 42511 is provided, and the limiting convex portion 42511 can cooperate with the convex teeth 4241 on the transmission gear 424 to control the unidirectional rotation of the transmission gear 424. When the operating mechanism 30 controls the bending angle of the bending portion of the endoscope through the connecting rope 20, the abutment member 421 is prevented from being displaced due to the push of the connecting rope 20, so that the movement amount of the operating mechanism 30 when the connecting rope 20 is retracted and released can be fully converted into the lifting amount of the bending portion of the endoscope. It should be noted that the upper limiting convex portion 42511 of the limiting unit 425 and the convex teeth 4241 on the transmission gear 424 can be specifically controlled by a ratchet and pawl-like cooperation mode to realize the unidirectional rotation control of the transmission gear 424, which will not be elaborated here.

[0059] like Figure 6 , Figure 8 As shown, illustratively, the limiting unit 425 includes a limiting plate 4251, an elastic limiting member 4252 and an elastic fixing frame 4253, the limiting plate 4251 can be swingably installed in the housing 10, the limiting convex portion 42511 is arranged on the limiting plate 4251 on the side facing the transmission gear 424, one end of the elastic limiting member 4252 is connected to the elastic fixing frame 4253, and the other end of the elastic limiting member 4252 abuts against the limiting plate 4251, so as to push the limiting plate 4251 to swing in the direction of the transmission gear 424, and realize the cooperation between the limiting convex portion 42511 and the convex tooth 4241. It should be noted that the above-mentioned elastic limiting member 4252 can be specifically set as a spring, a rubber sleeve or a bellows with high elasticity.

[0060] like Figure 1 As shown, in some embodiments, along the moving direction of the rack 423, the rack 423 is marked with a scale line 4231; wherein, the housing 10 is provided with a first window 11, and the scale line 4231 can be observed through the first window 11. In other words, the rack 423 can drive the scale line 4231 to move relative to the first window 11, so that the moving distance of the rack 423 can be directly observed, that is, the tightening degree of the connecting rope 20 can be observed in real time, so that the aging degree of the connecting rope 20 can be grasped in real time, so as to facilitate the subsequent inspection and maintenance of the endoscope operating unit 100.

[0061] like Figure 5 , Figure 7 As shown, exemplarily, the scale line 4231 includes a plurality of marking lines 42311, and the plurality of marking lines 42311 are sequentially arranged at intervals along the length direction of the rack 423, and the lengths of the plurality of marking lines 42311 sequentially increase or decrease along the length direction of the rack 423. In this way, each marking line 42311 can be different when passing through the first window 11 and being observed, so that people can directly determine the aging degree of the connecting rope 20 by directly observing the length of the marking line 42311 through the first window 11.

[0062] like Figure 5As shown, in some embodiments, the tightening mechanism 40 further includes a housing 43, the driving member 41, the driving gear 422 and the transmission gear 424 are all installed in the housing 43, the rack 423 partially extends outward relative to the housing 43, and the abutment member 421 is installed on one end of the rack 423 extending out of the housing 43, so that the tightening mechanism 40 can be assembled with the housing 43 as the installation basis, that is, the modularization of the overall structure of the tightening mechanism 40 is achieved, which can facilitate the assembly of the tightening mechanism 40 to the endoscope operating part 100. It should be noted that a second window 431 is provided on the housing 43, and the second window 431 is arranged corresponding to the first window 11, so that the scale line 4231 on the rack 423 can be observed through the second window 431 and the first window 11 in sequence.

[0063] like Figures 3 to 7 As shown, in some embodiments, the elastic fixing bracket 4253 is fixedly installed in the housing 43. The limit plate 4251 is rotatably connected to the outer shell 43, wherein the limit plate 4251 partially extends outward relative to the outer shell 43 and can swing relative to the outer shell 43, so that the limit plate 4251 can be manually driven to compress the elastic limit member 4252 to move and release the limit on the unidirectional rotation of the transmission gear 424. In this way, when the tightening mechanism 40 is assembled into the endoscope operating part 100, the part of the limit plate 4251 extending out of the outer shell 43 can be manually moved to release the limit on the unidirectional rotation of the transmission gear 424 by the limit plate 4251. After that, one of the abutment members 421 can be manually driven to move relative to the outer shell 43, and the abutment between the abutment member 421 and the connecting rope 20 will not affect the initial state of the connecting rope 20 in the endoscope operating part 100. In this way, the assembly relationship between the abutment member 421 on the tightening mechanism 40 and the connecting rope 20 can be easily adjusted.

[0064] Of course, in order to adjust the initial state relationship between the abutment member 421 on the tightening mechanism 40 and the connecting rope 20, it is not limited to the above-mentioned adjustment method of manually driving one of the abutment members 421. Figure 2 As shown, in some embodiments, an external support rod 401 is simultaneously inserted between the two abutment members 421 on the tightening mechanism 40, and the structural rigidity of the support rod 401 is used to adjust the distance between the two abutment members 421. Thereafter, the limit plate 4251 is released, so that the limit plate 4251 can automatically swing toward the direction of the transmission gear 424 under the push of the elastic limit member 4252, and realize the unidirectional rotation limitation of the transmission gear 424.

[0065] like Figure 2-Figure 4As shown, in some embodiments, the endoscope operating part 100 also includes a first support member 50, which is arranged on the side of the abutment member 421 facing the operating mechanism 30 and abuts against the connecting rope 20, and is used to support the connecting rope 20 in a tightened state. In this way, the stroke change of the connecting rope 20 caused by the abutment member 421 pushing the connecting rope 20 can be increased, thereby improving the tightening effect of the connecting rope 20 when the abutment member 421 pushes the connecting rope 20, so that the tightening mechanism 40 can achieve the maximum tightening of the connecting rope 20 within the limited space of the endoscope operating part 100.

[0066] like Figure 2-Figure 4 As shown, illustratively, the first support member 50 is configured as a support wheel, and the outer peripheral surface of the support wheel abuts against the connecting rope 20, wherein the support wheel is rotatably installed in the housing 10, so that the friction resistance encountered by the connecting rope 20 when passing through the support wheel can be reduced. Of course, for those skilled in the art, the first support member 50 can also be configured as a fixed block fixed on the housing 10, etc., which will not be elaborated here.

[0067] like Figure 2-Figure 4 As shown, in some embodiments, the endoscope operating part 100 further includes a second support member 60, which is disposed on the side of the abutment member 421 away from the first support member 50 and abuts against the connecting rope 20 to guide the connecting rope 20. In this way, the direction of the connecting rope 20 can be guided and constrained to prevent the connecting rope 20 from interfering with the arrangement of other components in the endoscope operating part 100 when tightened.

[0068] Similarly, the second support member 60 can be configured as a support wheel equal to the first support member 50, which will not be elaborated here.

[0069] In addition, the present application also provides an endoscope, including an endoscope bending portion (not shown) and the endoscope operating portion 100 described above; the endoscope bending portion is transmission-connected to the connecting rope 20 .

[0070] In summary, the endoscope operating part 100 for which protection is sought in the present application can utilize the energy storage state of the elastic member 411 to automatically tighten the connecting rope 20 that has become loose due to aging through the tightening assembly 42, and in the process of tightening the connecting rope 20, the tightening mechanism 40 can also achieve stepless adjustment of the tightening of the connecting rope 20, and ensure that the connecting rope 20 in the endoscope operating part 100 is always in a tightened state to facilitate operation by medical staff; in this process, there is no need for professional after-sales engineers to perform maintenance and debugging on the endoscope operating part 100 after disassembly, which can ensure the overall sealing of the endoscope using the endoscope operating part 100 and reduce costs.

[0071] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not used as limitations on the present application. As long as they are within the spirit of the present application, appropriate changes and modifications to the above embodiments are within the scope of protection required by the present application.
