Description

Connecting device and endoscope connecting system TECHNICAL FIELD

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

[0002] Endoscopes are classified according to the use scenarios, and can be divided into bronchoscopes, enteroscopes, gastroscope, etc. An endoscope is only an inspection instrument, and generally includes two parts, i.e. a handle and an imaging catheter connected to the handle. After the imaging catheter (provided with a camera at the front end) enters the natural cavity of the human body, it can take photos or videos. The images collected by the camera are transmitted to the host display connected to the handle of the endoscope through photoelectricity, so as to facilitate the doctor to observe whether there is pathological tissue (such as polyps, early cancer, etc.) in the natural cavity of the human body. If the doctor finds pathological tissue by means of the imaging catheter camera, the endoscope itself does not have a surgical function. The imaging catheter is generally provided with an instrument lumen, and a forceps channel hole is arranged on the handle and is in communication with the instrument lumen. When pathological tissue, such as a polyp, needs to be treated, a snare, a kind of endoscopic minimally invasive surgical consumable instrument, is inserted from the forceps channel hole to the target pathological tissue through the imaging catheter, and then a polyp resection operation is performed. After the resection is completed, the snare is withdrawn from the handle of the endoscope. If the imaging catheter lens finds bleeding after the resection, a hemostatic clip is inserted from the forceps channel hole, the hemostatic clip is released to clamp the tissue, and then the tissue is compressed to stop bleeding.

[0003] A choledochoscope is used for diagnosing and treating diseases occurring in the biliary tract (generally gallstones). The biliary tract is long and narrow, and the diameter of the imaging catheter of an ordinary endoscope, such as a duodenoscope, is close to 2 cm, which is obviously not suitable for directly treating pathological tissue in the biliary tract. The choledochoscope (also including a handle and an imaging catheter, and also provided with a forceps channel hole on the handle and an instrument lumen in the imaging catheter) is used as a minimally invasive surgical consumable instrument, the imaging catheter of the choledochoscope is inserted into the forceps channel hole of an endoscope (generally a duodenoscope), and then further enters the biliary tract (the diameter of the imaging catheter of the choledochoscope is generally less than 3 mm) through the imaging catheter of the duodenoscope to perform a stone removal or biopsy operation.

[0004] As can be seen from the above, the choledochoscope, as a sub-scope of the duodenoscope (also known as a mother scope), is used together with the duodenoscope and cannot be used independently. During the operation, the doctor needs to hold the duodenoscope and the choledochoscope at the same time, the mother scope (duodenoscope) cannot be moved at will after reaching the vicinity of the biliary tract, and therefore the relative fixation between the sub-scope (choledochoscope) and the mother scope (duodenoscope) needs to be maintained during the operation.

DETAILED DESCRIPTION

[0056] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0057] In the description of the present application and the embodiments thereof, it should be understood that the terms "top", "bottom", "height" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0058] In the present application and the embodiments thereof, unless otherwise explicitly specified and limited, the terms "set", "mount", "connected", "connected", "fixed" and the like should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrated; can be mechanically connected, can be electrically connected, or can be communicated; can be directly connected, or indirectly connected through an intermediate medium; can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0059] In the present application and embodiments thereof, unless otherwise explicitly specified and limited, a first feature is "on" or "under" a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature is "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is higher in horizontal height than the second feature. The first feature is "under", "below" and "underneath" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the first feature is lower in horizontal height than the second feature.

[0060] Referring to FIGS. 1-6, the present application provides a connecting device 1 which can be used to connect an endoscope child scope 2 and an endoscope parent scope 3, so that the relative positions of the two are fixed, and a doctor only needs to hold the endoscope child scope 2 or the endoscope parent scope 3, thereby reducing the difficulty of surgical operation.

[0061] In some possible embodiments, the connecting device 1 can include a first connecting part 11 and a second connecting device 12. The first connecting part 11 is used to connect the endoscope child scope 2, and the second connecting part 12 is connected to the first connecting part 11, and the second connecting part 12 and the endoscope parent scope 3 are detachably connected.

[0062] In the present application, the first connecting part 11 can be detachably connected to the endoscope child scope 2, and the second connecting part 12 can also be detachably connected to the endoscope parent scope 3. After the operation is completed, the first connecting part 11 can be detached from the endoscope child scope 2, and the second connecting part 12 can be detached from the endoscope parent scope 3, thereby facilitating the cleaning and storage of the endoscope child scope 2 and the endoscope parent scope 3, respectively.

[0063] The endoscope parent scope 3 can be a colonoscope or a gastroscope. Taking the endoscope parent scope 3 as a duodenoscope as an example, the endoscope child scope 2 can be a choledochoscope which is used in cooperation with the duodenoscope. During the operation, the doctor first inserts the imaging catheter of the duodenoscope into the natural cavity of the human body, and then takes photos or videos, thereby facilitating the doctor to observe whether there is a lesion tissue (such as a polyp, early cancer, etc.) in the natural cavity of the human body. If the doctor finds a lesion tissue, the imaging catheter of the choledochoscope needs to be inserted into the forceps channel hole of the duodenoscope, and then further enters the bile duct through the imaging catheter of the duodenoscope, so as to perform the stone removal or biopsy operation. During the operation, in order to reduce the difficulty of operation, the connecting device 1 can be pre-connected to the choledochoscope through the first connecting part 11, and when the choledochoscope is used later, the connecting device 1 can be quickly and effectively used in cooperation with the duodenoscope through the second connecting part 12, so that the doctor can hold the duodenoscope and the choledochoscope with one hand, thereby facilitating the doctor to operate the choledochoscope to perform the operation.

[0064] In some possible implementation forms, as shown in FIGS. 1-3, the second connecting part 12 encloses a sleeve cavity and a first opening 121 and a second opening 122 communicating with the sleeve cavity. In the direction from the first opening 121 to the second opening 122, the cross-sectional area of the sleeve cavity gradually increases. The second connecting part 12 is used to be sleeved on the endoscope parent scope 3 through the sleeve cavity, so as to connect the second connecting part 12 and the endoscope parent scope 3.

[0065] The second connecting part 12 can be a conical cylinder structure, and when the endoscope parent scope 3 is a gastroscope or enteroscope, a conical transition section is arranged between the handle and the imaging catheter of the endoscope parent scope 3. The large end of the conical transition section is close to the handle. The sleeve cavity of the second connecting part 12 provided in the embodiments of the present application is a conical cavity. After the second connecting part 12 is sleeved on the imaging catheter of the endoscope parent scope 3, the second connecting part 12 is continuously moved to the side of the handle of the duodenoscope, so that the second connecting part 12 and the conical transition section of the endoscope parent scope 3 are in close contact, thereby realizing the connection and cooperation of the second connecting part 12 and the endoscope parent scope 3. The second connecting part 12 and the conical transition section are in extrusion cooperation, have large frictional resistance and clamping force, and the connecting device 1 cannot be easily separated from the conical transition section of the endoscope parent scope 3.

[0066] The second connecting part 12 can adopt any one of the following two setting modes:

[0067] In the first setting mode, as shown in FIG. 6, the second connecting part 12 is a closed ring, and the outer wall of the second connecting part 12 is connected to the first connecting part 11. The second connecting part 12 can be a conical cylinder, and the second connecting part 12 needs to be pre-sleeved and fixed on the conical transition section of the endoscope parent scope 3 before the operation. When the endoscope child scope 2 is needed, the doctor assembles the endoscope child scope 2 on the first connecting part 11.

[0068] In the second setting mode, as shown in FIGS. 3 and 4, a first notch 123 is arranged on the second connecting part 12. The first notch 123 communicates with the sleeve cavity. The first notch 123 extends from the first port to the second port. The side of the second connecting part 12 opposite to the first notch 123 is connected to the first connecting part 11.

[0069] In this embodiment, the second connecting part 12 is not a closed cylinder, but a tapered cylinder with a long first notch 123. The first notch 123 can be a long slot, and the width of the first notch 123 is not less than the outer diameter of the partial structure (imaging conduit) of the endoscope mother scope 3, so that the endoscope mother scope 3 can be inserted into the sleeve cavity through the long slot. In this second arrangement, the connecting device 1 does not need to be assembled in the endoscope mother scope 3 in advance, but can be assembled and connected with the endoscope daughter scope 2 through the first connecting part 11. When the endoscope daughter scope 2 is needed during the operation, the second connecting part 12 is assembled and connected with the endoscope mother scope 3. In the specific operation process, the connecting device 1 can be moved so that the imaging conduit of the endoscope mother scope 3 passes through the first notch 123 and enters the sleeve cavity of the second connecting part 12, and then the connecting device 1 is moved upward, so that the second connecting part 12 is tightly sleeved on the tapered transition section of the endoscope mother scope 3. When it is needed to remove the paired use state, the endoscope mother scope 3 can be moved upward relative to the connecting device 1, so that the endoscope mother scope 3 and the connecting device 1 can be quickly separated.

[0070] In some possible embodiments, referring to FIG. 3, the connecting device 1 can include a sheath 13, which is a flexible body and is at least partially located in the sleeve cavity. In the state that the second connecting part 12 is connected with the endoscope mother scope 3, the sheath 13 is compressed and arranged between the endoscope mother scope 3 and the inner wall of the sleeve cavity.

[0071] The sheath 13 can be made of silicone or rubber material. In the state that the tapered transition section of the endoscope mother scope 3 penetrates the second connecting part 12, one side of the sheath 13 along the thickness direction is attached to the surface of the tapered transition section, and the other side of the sheath 13 along the thickness direction is attached to the inner wall of the sleeve cavity. The sheath 13 plays a role of buffering protection.

[0072] In some possible embodiments, referring to FIG. 3, the sheath 13 has a sheath body 131 and a port edge covering rib 132. The sheath body 131 has two ports, and the port edge covering rib 132 is arranged on each of the two ports. In the state that the sheath 13 is connected to the second connecting part 12, the sheath body 131 is attached to the inner wall of the sleeve cavity, and the two port edge covering ribs 132 are respectively covered on the end surface of the edge of the first opening 121 of the second connecting part 12 and the end surface of the edge of the second opening 122 of the second connecting part 12.

[0073] In this embodiment, the port edge covering rib 132 protrudes from the outer surface of the sheath body 131, and in the state where the sheath 13 is connected to the second connecting part 12, the sheath body 131 is located inside the sleeve cavity, and the port edge covering rib 132 at both ends of the sheath body 131 directly covers the end surface of the port of the second connecting part 12, so as to avoid the sharp edges on the end surface directly contacting the endoscope parent mirror 3 and cutting or damaging the endoscope parent mirror 3.

[0074] It should be noted that, as shown in FIG. 6, when the second connecting part 12 is a closed cylindrical structure, the sheath 13 can be correspondingly provided as a closed annular cylindrical structure. As shown in FIG. 3, when the second connecting part 12 is a cylindrical structure with an opening, the sheath 13 can be correspondingly provided as a cylindrical structure with an opening.

[0075] In some possible embodiments, as shown in FIG. 3, a second notch 133 is arranged on the sheath body 131, and the second notch 133 is respectively communicated with the two ports. The sheath 13 is provided with a notch edge covering rib 134 arranged on the sheath body 131, and the notch edge covering rib 134 is located at the edge of the second notch 133. In the state where the sheath 13 is connected to the second connecting part 12, the notch edge covering rib 134 covers the thickness end surface of the edge of the first notch 123 of the second connecting part 12.

[0076] In this embodiment, the sheath 13 is not a closed cylindrical structure. In the state where the sheath 13 is connected to the second connecting part 12, the second notch 133 and the first notch 123 are located opposite to each other and are communicated with each other. The notch edge covering ribs 134 on both sides of the edge of the second notch 133 protrude from the outer surface of the sheath body 131 and can smoothly cover the thickness end surface of the first notch 123 of the sheath body 131.

[0077] In some possible embodiments, the first connecting part 11 includes a main shell 111 and a plurality of cards 112. The second connecting part 12 is connected to the main shell 111, each of the cards 112 is connected to the main shell 111, and each of the cards 112 is arranged along the edge of the main shell 111 in sequence and at intervals. In the state where the first connecting part 11 and the endoscope child mirror 2 are connected, the main shell 111 is attached to the endoscope child mirror 2, and each of the cards 112 is respectively clamped to the outer wall surface of the medical instrument.

[0078] The first connecting part 11 is provided with a plurality of clamping spaces formed by the plurality of cards 112. The endoscope sub-scope 2 is generally provided with a handle. The handle is shaped to match the clamping space, and the outer contour of the handle is slightly larger than the clamping space. During the process of inserting the handle of the endoscope sub-scope 2 into the clamping space, the handle of the endoscope sub-scope 2 can push apart the plurality of cards 112, and the plurality of cards 112 are deformed. When the handle is completely inserted into the clamping space, the plurality of cards 112 are restored to the original shape and are clamped on the handle, thereby connecting and fixing the handle and the first connecting part 11. The plurality of cards 112 are respectively elastically attached to different positions of the handle, thereby firmly clamping the connecting device 1 on the endoscope sub-scope 2.

[0079] In some possible embodiments, as shown in FIG. 4, the main shell 111 is provided with a reinforcing rib 1111 on the side away from the second connecting part 12. The reinforcing rib 1111 can include a plurality of interlaced ribs, forming a grid-shaped reinforcing rib 1111, thereby strengthening the connection structure between the second connecting part and the plurality of cards 112, and improving the overall rigidity of the connecting device 1 during use.

[0080] In some possible embodiments, as shown in FIG. 3, the main shell 111 is provided with a reinforcing back plate 1112 on the side away from the plurality of cards 112, and the second connecting part 12 is connected to the reinforcing back plate 1112. The reinforcing back plate 1112 increases the structural strength and rigidity of the main shell 111, improves the overall rigidity of the connecting device 1 during use, and minimizes the relative movement between the endoscope sub-scope 2 and the endoscope main scope 3, so that the two are integrated after being connected by the connecting device 1.

[0081] In some possible embodiments, the endoscope sub-scope 2 is provided with a plurality of functional parts 21. In the state of connecting the first connecting part 11 and the endoscope sub-scope 2, at least part of the functional parts 21 are located on the gap between the adjacent cards 112.

[0082] When the endoscope sub-scope 2 is a choledochoscope, the functional parts 21 can include a photographing button, a locking control button, a liquid injection port, and the like. The positions of the plurality of cards 112 can avoid the plurality of functional parts 21, and do not affect the normal use of the endoscope sub-scope 2.

[0083] In some possible implementation, the endoscope sub-scope 2 is provided with an outwardly convex forceps channel nozzle 22, the forceps channel nozzle 22 has a forceps channel nozzle opening, in the state that the first connecting part 11 and the endoscope sub-scope 2 are connected, one of the cards 112 is clamped on the outer wall surface of the forceps channel nozzle 22. The handle of the endoscope sub-scope 2 is provided with a photographing button, a locking control button, and a liquid injection port, and the handle is also provided with a forceps channel nozzle opening which is communicated with the forceps channel of the endoscope sub-scope 2. The forceps channel nozzle 22 protrudes from the handle and extends along the smooth circumferential surface of the handle for a long distance. If the card 112 is misaligned with the forceps channel nozzle 22, the connection structure of the first connecting part 11 and the endoscope sub-scope 2 is unstable, and the card 112 is easily disengaged. In the embodiment of the present application, one of the cards 112 can be tightly attached to the outer wall surface of the forceps channel nozzle 22 without blocking the forceps channel nozzle opening of the forceps channel nozzle 22, so that each card 112 on the first connecting part 11 is evenly clamped on the handle of the endoscope sub-scope 2, and the assembly stability is improved.

[0084] In some possible implementation, as shown in FIG. 5, the first connecting part 11 is provided with a first side edge 113 and a second side edge 114 on both sides in the width direction, respectively, and the distance between the second connecting part 12 and the first side edge 113 is less than the distance between the second connecting part 12 and the second side edge 114.

[0085] When the endoscope sub-scope 2 is a choledochoscope, the handle of the endoscope sub-scope 2 is provided with a rotating wheel 25, the rotating wheel 25 is located on the side of the handle away from the first connecting part 11, and the imaging catheter end bending angle and bending direction of the endoscope sub-scope 2 can be adjusted by rotating the rotating wheel 25. In the embodiment of the present application, the second connecting part 12 is not arranged at the middle position of the first connecting part 11 in the width direction, but is close to one width edge of the first connecting part 11, and the second connecting part 12 is offset from the center, thereby forming a lever structure. The rotating axis of the second connecting part 12 and the rotating wheel 25 has a certain distance, the moment is increased, the torsion of the rotating wheel 25 of the matched medical instrument in the rotating process can be easily offset, so that the endoscope sub-scope 2 is not subjected to excessive force when the rotating wheel 25 is rotated, and the handle of the endoscope sub-scope 2 and the endoscope main scope 3 do not have large deviation, and the operation precision of the surgery is improved.

[0086] The embodiment of the present application also provides an endoscope connecting system, which comprises the connecting device 1 and the endoscope sub-scope 2.

[0087] The endoscope connecting system further comprises an endoscope main scope 3, which is detachably connected with the second connecting part 12 of the connecting device 1.

[0088] In the embodiments of the present application, the first connecting part 11 of the connecting device 1 of the endoscope connecting system can be detachably connected with the endoscope child scope 2, and the second connecting part 12 can also be detachably connected with the endoscope parent scope 3. After the operation is completed, the first connecting part 11 can be detached from the endoscope child scope 2, and the second connecting part 12 can be detached from the endoscope parent scope 3, so as to facilitate the cleaning and storage of the endoscope child scope 2 and the endoscope parent scope 3, respectively.

[0089] The second connecting part 12 of the connecting device 1 can be quickly matched with the endoscope parent scope 3 by being sleeved on the endoscope parent scope 3, and when the endoscope parent scope 3 needs to be detached, the endoscope parent scope 3 only needs to be moved upward relative to the connecting device 1, so that the endoscope parent scope 3 and the connecting device 1 are relatively fixed in the radial direction of the imaging guide tube. The connecting device 1 has a simple structure, and the matching and disengaging operation between the child scope and the parent scope are convenient. The first connecting part 11 of the connecting device 1 is connected with the endoscope child scope 2 through the clamping of the plurality of clamping pieces 112.

[0090] In some possible embodiments, the detachment direction of the endoscope child scope 2 and the first connecting part 11 is different from the detachment direction of the endoscope parent scope 3 and the second connecting part 12. When an external force is applied to the endoscope parent scope 3 to detach the endoscope parent scope 3 from the connecting device 1, the connecting relationship between the connecting device 1 and the endoscope child scope 2 is not affected, and the connecting device 1 and the endoscope child scope 2 can remain in the connected state and are not affected.

[0091] In some possible embodiments, an external force applied in the horizontal direction of the operating handle of the endoscope child scope 2 can detach the endoscope child scope 2 from the first connecting part 11. The term “in the horizontal direction of the operating handle of the endoscope child scope” can be understood as being in the thickness direction of the operating handle, or can be understood as the arrangement direction of the first connecting part 11 and the second connecting part 12 of the connecting device 1.

[0092] In some possible embodiments, an external force applied in the vertical direction of the imaging guide tube of the endoscope parent scope 3 can detach the endoscope parent scope 3 from the second connecting part 12.

[0093] It can be seen that the detachment direction of the endoscope child scope 2 and the first connecting part 11 is substantially perpendicular to the detachment direction of the endoscope parent scope 3 and the second connecting part 12. When one of the endoscope parent scope 3 and the endoscope child scope 2 is detached by an external force, the connecting state of the other and the connecting device 1 is not affected.
