Description
Adjustable locking winding module and endoscope Technical Field
[0001] This invention relates to the field of endoscope technology, specifically to a winding module with adjustable locking degree and an endoscope. Background Technology
[0002] Endoscopes include, for example, the transoral cholangioscopy. Transoral cholangioscopy is used in gastroenterological surgery to manage diseases of the bile duct and pancreatic duct. Currently, cholangioscopy instruments on the market come in various forms and possess multiple functions to facilitate ERCP (Endoscopic Retrograde Cholangiopancreatography) procedures. One crucial function of cholangioscopy is its locking mechanism. Currently available cholangioscopy instruments generally only have a locked and unlocked state, lacking a semi-locked state. The semi-locked state can be understood as the suspension of the curved section within the insertion part at its current bending angle. In the semi-locked state, the operator can still adjust the bending angle of the curved section without needing to unlock it, increasing the number of surgical steps and significantly increasing operator fatigue. Summary of the Invention

[0005] Optionally, the adjustable locking degree winding module further includes a drive mechanism that drives the interference member and / or the winding reel to perform the relative movement stroke.
[0006] Optionally, two mating parts are provided at intervals along the axial direction of the winding reel, which are respectively the first mating part and the second mating part, and one interference part is provided;
[0007] The winding reel is fixed in its axial position, and the interference element is movable and translatable along the axial direction of the winding reel.
[0008] Optionally, the reel includes: a reel body rotatably disposed about its own axis under external force; and an elastic member protruding from the radial outer wall of the reel body, the elastic member constituting the first mating part; wherein, when in the locked state, the elastic member is squeezed and deformed by the interference part to restrict the reel body from continuing to rotate about its own axis under the original external force.
[0009] Optionally, the radial outer wall of the disc is provided with an annular groove along its circumference; the elastic element is sleeved in the annular groove in a ring shape.
[0010] Optionally, the reel includes a reel body rotatably disposed about its own axis; one of the radial outer wall of the reel body and the side wall of the interference member is provided with a limiting protrusion, and the other is provided with a limiting groove. When in the locked state, the limiting protrusion and the limiting groove are connected in a concave-convex manner to restrict the rotation of the reel body about its own axis; the limiting protrusion and the limiting groove respectively constitute the second mating part and the interference part.
[0011] Optionally, the limiting protrusion constitutes the interference portion, and the outer surface of the limiting protrusion is provided in a convex arc shape; and / or, one of the radial outer wall of the disk body and the side wall of the interference member is provided with a first gear tooth, and the other is provided with a second gear tooth, and the first gear tooth and the second gear tooth are respectively arranged in multiple circumferentially along the disk body, the first gear tooth constitutes the limiting protrusion, and the limiting groove is defined between every two adjacent second gear teeth.
[0012] Optionally, the adjustable locking degree winding module further includes a drive mechanism, the drive mechanism comprising: a rotating shaft rotatably disposed on the radial side of the winding reel about its own axis, the rotation axis of the rotating shaft being parallel to the rotation axis of the winding reel; and an operating member extending radially along the rotating shaft, one end of which is fixedly connected to the rotating shaft so as to drive the rotating shaft to rotate when the other end of the operating member is swung by an external force; wherein the interfering member has a groove on the side wall facing the rotating shaft, the shape of the groove being adapted to the shape of the radial outer wall of the rotating shaft, one of the groove and the radial outer wall of the rotating shaft having a guide protrusion, and the other having a guide groove, the guide groove extending obliquely along the axial and circumferential directions of the rotating shaft, respectively.

[0015] In the technical solution provided by this invention, the spool can wind and unwind the thread by rotating forward and backward around itself, thereby achieving bending adjustment for the insertion body. By manipulating the interference part and the mating part to approach and abut against each other, interference is generated between the interference part and the spool, hindering the continued rotation of the spool. Since different interference parts and mating parts generate different amounts of interference when they abut against each other, different degrees of interference are generated between the interference part and the spool, resulting in different degrees of locking of the spool's rotation. This ensures that the spool device has at least a fully locked state, a partially locked state, and an unlocked state. Furthermore, since the switching and adjustment between different interference parts and mating parts in this invention is directly achieved by manipulating the interference part and / or the spool to move axially, it features a simple structure and convenient operation, helping to improve the operator's operational quality during surgery.

[0030] Please refer to Figures 1 to 7. This invention provides a winding module with adjustable locking degree and an endoscope in which it is applied. The specific type of endoscope is not limited; for example, it can be a cholangioscope as described above.
[0031] Specifically, the adjustable locking degree winding module includes a winding device 200 and an interference member 300. The winding device 200 includes a winding reel rotatable about its own axis, with its radial outer wall defining a mating portion. The interference member 300 is located on one radial side of the winding reel and has an interference portion facing the mating portion. At least two mating portions and / or interference portions are provided axially on the winding reel. The winding reel and the interference member 300 have a relative travel distance axially on the winding reel, allowing for adjustment of the different interference portions and mating portions during their relative travel distance to achieve a locking state of approaching and abutting each other, and an unlocking state of separation. In the locking state, the amount of interference generated between different interference portions and mating portions is different.
[0032] In the technical solution provided by this invention, the suture reel can wind and unwind the suture by rotating around itself in the forward and reverse directions, thereby achieving bending adjustment for the insertion body. By manipulating the interference part and the mating part to approach and abut against each other, interference is generated between the interference member 300 and the suture reel, hindering the continued rotation of the suture reel. Since different interference parts and mating parts generate different amounts of interference when they abut against each other, different degrees of interference are generated between the interference member 300 and the suture reel, resulting in different degrees of locking of the suture reel's rotation. This ensures that the suture winding device 200 has at least a fully locked state, a partially locked state, and an unlocked state. Furthermore, since the switching and adjustment between different interference parts and mating parts in this invention is directly achieved by manipulating the interference member 300 and / or the suture reel to move axially, it features a simple structure and convenient operation, helping to improve the operator's operational quality during surgery.
[0033] It is understandable that an endoscope generally consists of a connected operating body and an insertion body.
[0034] The operating body generally refers to a main structure that does not intervene in the patient's body during medical procedures and can be held by the operator to manipulate the inserted body and external instruments inserted within it. Based on this, the operating body is generally designed for easy hand-held operation, such as a handle, gun-like shape, or grip. Typically, the operating body includes a housing 100 and various functional components disposed within the housing 100. For example, the aforementioned adjustable locking coil module can be one of these functional components.
[0035] The insert body refers to an elongated tubular structure that is at least partially inserted into the patient's body during a medical procedure to reach the affected area. Generally, the insert body is inserted and fixed to one end of the operating body and extends elongatedly away from the operating body. The end of the insert body away from the operating body typically forms a head end. The insert body generally has a working channel and an installation channel along its axial direction. The installation channel is for mounting, for example, imaging devices and / or illumination devices. The imaging device is used to acquire images of the affected area during medical procedures; it can be, but is not limited to, a CMO (Complementary Metal-Oxide-Semiconductor) image sensor. The illumination device is used to illuminate the affected area during medical procedures, assisting the imaging device in acquiring images; it can be, but is not limited to, built-in light sources such as LEDs, or devices such as optical fibers that guide light from external light sources to the head end. The working channel is generally used for inserting external diagnostic and therapeutic instruments, or for procedures such as suction and fluid delivery.
[0036] In view of the above, in order to make the orientation of the head end adjustable, at least a partial segment of the inserted body constitutes a curved segment. The curved segment can bend laterally toward at least one side of its radial direction, thereby causing the distal segment to bend, ultimately achieving the purpose of adjusting the orientation of the imaging device and / or illumination device at the head end.
[0037] At this time, in addition to the aforementioned winding reel, the winding device 200 generally also includes a traction wire. One end of the traction wire extends axially along the insertion body to connect and fix with a radial sidewall of the bent section; the other end of the traction wire is wound around a winding groove on the radial outer peripheral sidewall of the winding reel. Thus, when the winding reel rotates around its own axis in the forward direction, the traction wire can be wound up, thereby pulling the sidewall of the bent section and causing the bent section to bend laterally; conversely, when the winding reel rotates around its own axis in the reverse direction, the traction wire can be released, thereby removing the pulling force on the traction wire and allowing the bent section to return to its naturally straightened state.
[0038] Of course, the rotation of the aforementioned reel can be achieved automatically by a specially designed power component; or the rotation of the aforementioned reel can be directly achieved manually by the operator. Taking manual operation as an example, the reel generally includes a reel body, which is roughly a disc structure with a certain thickness, and its outer peripheral sidewall is provided with the aforementioned winding groove. In addition, the reel generally also includes a convex shaft protruding from one axial end of the reel body, and the central axis of the convex shaft is collinear with the rotation axis 410 of the reel. In this case, the winding device 200 may also include a rotating wheel, which is connected and fixed to the free section of the convex shaft. Generally, the reel body and one section of the convex shaft are housed within the housing 100; the other section of the convex shaft extends outward from the housing 100 and is connected and fixed to the rotating wheel located outside the housing 100. In this way, the operator can manually rotate the rotating wheel to drive the reel body to rotate, thereby realizing the aforementioned winding and unwinding operations.
[0039] It should be noted that in practical applications, the aforementioned bending segment can be set to one or at least two; the same bending segment can be bent unidirectionally, radially on both sides, or in multiple radial directions. Therefore, correspondingly, one or two traction wires can be wound on the same reel. Alternatively, the same adjustable locking degree winding module can include at least two winding devices 200. Taking the structure shown in Figures 1 to 7 as an example, the adjustable locking degree winding module includes two winding devices 200. One winding device 200 includes a first reel 210 and a first rotating wheel 231; the first reel 210 includes a first disc body 211 and a first convex shaft 212. The other winding device 200 includes a second reel 220 and a second rotating wheel 232; the second reel 220 includes a second disc body 221 and a second convex shaft 222. Specifically, the first disc 211 and the first convex shaft 212 are provided with insertion holes along their axial direction; the second disc 221 is stacked on the end of the first disc 211 opposite to the first convex shaft 212, and the second convex shaft 222 passes through the aforementioned insertion holes and is connected to the second rotating wheel 232, such that the second rotating wheel 232 is stacked on the end of the first rotating wheel 231 opposite to the first disc 211. A baffle 250 may be provided between the first disc 211 and the second disc 221. This achieves a more compact structural design for the two winding devices 200.
[0040] In view of the above-described embodiment of the winding device 200, the interference member 300 is disposed on the radial side of the winding reel, and the interference member 300 includes an interference segment 310 having an interference surface facing the winding reel. The interference surface is generally circumferential along the winding reel and is concave arc-shaped to suit the shape of the winding reel at its location. The radial outer wall of the winding reel defines a mating portion, and correspondingly, the interference portion is defined on the interference surface.
[0041] The reel and the interference member 300 have a relative travel distance along the axial direction of the reel. Specifically, the position of the reel relative to the housing 100 can be fixed, while the interference member 300 can move relative to the housing 100 along the axial direction of the reel; or the position of the interference member 300 can be fixed relative to the housing 100, while the reel can move relative to the housing 100 along its axial direction; or both the reel and the interference member 300 can move relative to the housing 100 along the axial direction of the reel, and their movements can be opposite or differential in the same direction. For ease of understanding, in the following embodiments, the example of the reel being fixed relative to the housing 100 and the interference member 300 being movable relative to the housing 100 along the axial direction of the reel is used for explanation. In this way, interference between the adjustment process of the locking degree and the rotation operation process of the reel can be avoided as much as possible.
[0042] Next, during the relative movement of the reel and the interference member 300, if the interference part and the mating part are not in contact and are separated, there is basically no mutual interference between them. That is, the interference member 300 will not affect the winding and unwinding process of the reel and is in an unlocked state. The operator can operate the reel to rotate without hindrance, thereby adjusting the bending of the bent section of the inserted body. However, if the interference part and the mating part are in contact and abut against each other, there will be mutual interference. That is, the interference member 300 will hinder the winding and unwinding process of the reel and is in a locked state.
[0043] To enable at least two locking degrees in the locked state, the present invention designs at least two interference portions and / or mating portions along the axial direction of the winding reel, i.e., along the relative displacement path between the winding reel and the interference member 300. Specifically, at least two interference portions may be sequentially arranged along the axial direction of the winding reel; or at least two mating portions may be sequentially arranged along the axial direction of the winding reel; or both interference portions and mating portions may be sequentially arranged in at least two along the axial direction of the winding reel. For ease of understanding, in the following embodiments, two mating portions are provided along the axial direction of the winding reel, specifically a first mating portion and a second mating portion. In this case, there is only one interference portion.
[0044] It should be noted that the above configuration refers to the quantity relationship between the mating parts and interference parts between the same winding device 200 and the interference member 300. For example, when there are at least two winding reels as described above, the mating parts defined on each winding reel can be one or at least two; and / or the interference parts on the interference member 300 corresponding to each winding reel can be one or at least two. Wherein, when a first mating part and a second mating part are defined on each winding reel, if the adjustment requirements of the locking state of the two winding reels can be achieved simultaneously, then the interference member 300 is set to correspond one-to-one with the two winding reels and is set to two; or the interference surface of the interference member 300 extends along the axial direction of the winding reel to be sufficient to cover the first winding reel 210 and the second winding reel 220, and two interference parts are spaced apart along the axial direction of the winding reel on the interference surface, one of which, during its activity, mates with the first mating part and the second mating part at the first winding reel 210 respectively; and the other interference part, during its activity, mates with the first mating part and the second mating part at the second winding reel 220 respectively. Alternatively, if the adjustment of the locking state of the two reels does not need to be achieved simultaneously, but only individually, then only one interference part can be provided on the interference member 300. In this case, during the relative active stroke, the interference member 300 can cooperate with the first and second mating parts at the first reel 210, and with the first and second mating parts at the second reel 220, respectively.
[0045] Based on one or more of the above embodiments, it can be understood that a first interference amount is formed between the interference part and the first mating part, and a second interference amount is formed between the interference part and the second mating part. The first interference amount is set to be different from the second interference amount, and specifically, the first interference amount can be set to be less than the second interference amount. Thus, when the interference part moves to abut against the first mating part, it is in a semi-locked state. At this time, without applying external force, or with the original external force continuing to be applied, the first reel 210 / second reel 220 remains non-rotating, which is equivalent to hovering. When another external force greater than the original external force is applied, the first reel 210 / second reel 220 can be driven to rotate, continuing to adjust the curvature of the bent section of the inserted body. When the interference part moves to abut against the second mating part, it is in a fully locked state. At this time, under almost any external force (any external force that does not cause structural damage), the first reel 210 / second reel 220 remains non-rotating, which is equivalent to stopping.
[0046] It should be noted that the above-mentioned semi-locked state does not constitute a limitation on the degree of locking. That is, the semi-locked state is not strictly limited to 50% of the fully locked state, but can be any suitable degree of locking between the unlocked state and the fully locked state.
[0047] There are various specific solutions for implementing the first mating part. In one embodiment, if the winding reel includes a reel body as described above, and the reel body is rotatable around its own axis under the drive of an external force, the winding reel may also include an elastic element 241. The elastic element 241 protrudes from the radial outer wall of the reel body, and the elastic element 241 constitutes the first mating part. In the locked state, the elastic element 241 is squeezed and deformed by the interference part to restrict the reel body from continuing to rotate around its own axis under the original external force.
[0048] It is understood that the elastic element 241 can be arranged only in a local area of the circumference of the disc, or the elastic element 241 can be arranged along the entire circumference of the disc. Specifically, the elastic element 241 can extend in a ring shape along the circumference of the disc. In this case, the radial outer wall of the disc is provided with an annular groove along its circumference; the elastic element 241 is sleeved in the annular groove in a ring shape.
[0049] The elastic element 241 has at least the ability to expand and contract in the radial direction of the disc. In its natural state, the elastic element 241 protrudes radially from the outer radial wall of the disc, such that when the interfering part is moved to face the outer radial wall of the disc, the interfering part and the outer radial wall maintain a distance (the distance is no greater than the protrusion height of the elastic element 241 from the outer radial wall) or just touch, without interfering with each other, and are in an unlocked state. When the interfering part is moved to the elastic element 241, a radial compressive force is generated on the elastic element 241, causing it to deform and subsequently exert a reverse force on the interfering part 300. That is, frictional damping is generated between the interfering part and the elastic element 241, hindering the continued rotation of the disc.
[0050] There are various specific solutions for implementing the second mating part. In one embodiment, if the reel includes a reel body as described above, and the reel body is rotatable around its own axis under external force, one of the radial outer wall of the reel body and the side wall of the interference member 300 is provided with a limiting protrusion 311a, and the other is provided with a limiting groove 242a. When in the locked state, the limiting protrusion 311a and the limiting groove 242a are connected in a concave-convex manner to restrict the rotation of the reel body around its own axis. The limiting protrusion 311a and the limiting groove 242a respectively constitute the second mating part and the interference part. It can be understood that the limiting protrusion 311a and the limiting groove 242a mainly refer to the limiting in the radial direction of the reel body, and there is no limiting in the axial direction of the reel body. That is, at least the limiting groove 242a is through in the axial direction of the reel body, which facilitates the relative movement of the reel body and the interference member 300 along the axial direction. Through the interlocking connection between the limiting protrusion 311a and the limiting groove 242a, unless the external force is so great that it causes structural damage to the limiting protrusion 311a and / or the limiting groove 242a, the winding reel cannot continue to rotate within a certain range of external force, thus achieving a completely locked state.
[0051] Similarly, specifically, the interference member 300 may have a limiting protrusion 311a, which constitutes an interference portion; the radial outer wall of the disk may have a limiting groove 242a, which constitutes a second mating portion. Alternatively, the interference member 300 may have a limiting groove 242a, which constitutes an interference portion; the radial outer wall of the disk may have a limiting protrusion 311a, which constitutes a second mating portion. Of course, the interference member 300 may have both a limiting protrusion 311a and a limiting groove 242a, both of which constitute interference portions; the radial outer wall of the disk may have corresponding limiting grooves 242a and 311a, both of which constitute a second mating portion.
[0052] As shown in Figures 1 to 7, the interference member 300 has a limiting protrusion 311a, and the outer surface of the limiting protrusion 311a is convex arc-shaped. This convex arc-shaped design allows the interference member 300 to move more smoothly between the first mating part, the second mating part, and the remaining radial outer wall of the reel when it moves axially along the winding reel. Especially when the first mating part is defined by the elastic member 241 as described above, the convex arc-shaped limiting protrusion 311a maximizes the contact area with the elastic member 241, reduces stress concentration, and thus helps to improve the service life of the elastic member 241.
[0053] One of the radial outer wall of the disc body and the side wall of the interference member 300 is provided with a first gear tooth 242, and the other is provided with a second gear tooth 311. Multiple first gear teeth 242 and second gear teeth 311 are spaced apart along the circumference of the disc body. The first gear teeth 242 form a limiting protrusion 311a, and a limiting groove 242a is defined between every two adjacent second gear teeth 311. Specifically, for example, the second gear teeth 311 protrude from the radial outer wall of the disc body, and the second gear teeth 311 can be arranged in a local area along the circumference of the disc body or along the entire circumference of the disc body. The aforementioned limiting groove 242a is defined at the interval between every two adjacent second gear teeth 311. Thus, at any position during the rotation of the disc body, at least one limiting groove 242a is connected to at least one limiting protrusion 311a, achieving a complete locking effect.
[0054] Based on the above, the relative movement of the reel and the interference element 300 along the axial direction of the reel can be directly achieved by the user manually operating the reel (or wheel) and driving the interference element 300. Alternatively, in one embodiment, the reel module with adjustable locking degree further includes a drive mechanism 400, which drives the interference element 300 and / or the reel to perform the aforementioned relative movement. Again, taking the example of the interference element 300 being movable and the reel being relatively fixed, the drive mechanism 400 can be driven to connect with the interference element 300. Based on the structure shown in Figures 1 to 7, specifically, the drive mechanism 400 includes a rotating shaft 410 and an operating member 430. The rotating shaft 410 is rotatably disposed on the radial side of the winding reel around its own axis, and the rotation axis 410 line of the rotating shaft 410 is parallel to the rotation axis 410 line of the winding reel. The operating member 430 extends radially along the rotating shaft 410, and one end is fixedly connected to the rotating shaft 410 so that when the other end of the operating member 430 is swung by an external force, the rotating shaft 410 is rotated. The interference member 300 has a groove 321 on the side wall facing the rotating shaft 410. The shape of the groove 321 is adapted to the shape of the radial outer wall of the rotating shaft 410. One of the groove 321 and the radial outer wall of the rotating shaft 410 has a guide protrusion 411, and the other has a guide groove 322. The guide groove 322 extends obliquely along the axial and circumferential directions of the rotating shaft 410, respectively.
[0055] Specifically, the operating component 430 has a connecting section and an operating section. The connecting section can be directly connected to the rotating shaft 410, or it can be connected to the rotating shaft 410 via, for example, a connecting shaft 420, with the connecting shaft 420 and the rotating shaft 410 coaxially mounted. The connecting section extends generally radially along the rotating shaft 410, and the operating section can bend and extend axially from the end of the connecting section away from the rotating shaft 410 towards the rotating shaft 410 for easier hand-held operation. After the adjustable locking winding module is installed into the housing 100, at least the operating section can extend outwards from the housing 100 and be exposed outside the housing 100.
[0056] The interference member 300 also includes a drive section 320, which is connected to the interference section 310 and is oriented toward the rotating shaft 410. Since the radial outer wall of the rotating shaft 410 is convex, in order to shorten the mating distance between the drive section 320 and the rotating shaft 410, the drive section 320 may be provided with a groove 321. The groove 321 is concave and is adapted to the shape of the radial outer wall of the rotating shaft 410 at its location.
[0057] Similarly, the groove 321 may have a guide protrusion 411, and the radial outer wall of the rotating shaft 410 may have a guide groove 322. Alternatively, the groove 321 may have a guide groove 322, and the radial outer wall of the rotating shaft 410 may have a guide protrusion 411. Of course, the groove 321 may have both a guide protrusion 411 and a guide groove 322, and the radial outer wall of the rotating shaft 410 may have corresponding guide grooves 322 and guide protrusions 411. As shown in Figures 1 to 7, the radial outer wall of the rotating shaft 410 may have a guide protrusion 411, and the groove 321 may have a guide groove.
[0058] When the operator holds the operating section and swings the connecting section, the connecting shaft 420 drives the rotating shaft 410 to rotate around its own axis, which in turn causes the guide protrusion 411 to slide along the guide groove 322. Since the guide groove 322 extends inclinedly along the circumference and axial direction of the rotating shaft 410, the circumferential rotation of the rotating shaft 410 can be converted into the axial translation of the interference member 300 as a whole along the rotating shaft 410. And since the axial direction of the rotating shaft 410 is parallel to the axial direction of the winding reel, it can ultimately achieve the axial translation of the interference member 300 as a whole along the winding reel, which has the characteristics of simple structure and convenient operation.

Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
