Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to an endoscope connecting device. BACKGROUND
[0002] An endoscope generally comprises two parts, a handle and an imaging catheter connected to the handle. After the imaging catheter enters the natural cavity of the human body, it takes photos or videos. When the imaging catheter observes the diseased tissue, the snare reaches the target diseased tissue through the instrument channel on the imaging catheter, and then the polypus is removed. After the operation is completed, the snare is withdrawn from the endoscope handle.
[0003] A choledochoscope is used for diagnosing and treating diseases in the biliary tract. The biliary tract is long and narrow, and the diameter of the imaging catheter of a common endoscope, such as a duodenoscope, is close to 2 cm, which is obviously not suitable for directly treating the diseased tissue in the biliary tract. The choledochoscope, like the snare described above, is a minimally invasive surgical consumable instrument. The imaging catheter of the choledochoscope is inserted into the forceps channel of the endoscope (usually a duodenoscope), and then further inserted into 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 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 the mother scope), is used together with the duodenoscope and cannot be used independently. During the operation, the operator needs to hold the sub-scope and the mother scope at the same time. After the mother scope reaches the vicinity of the biliary tract, it cannot be moved at will, so the relative fixation between the sub-scope and the mother scope needs to be maintained during the operation.
[0005] The conventional way is to use a flexible band to keep the sub-scope and the mother scope relatively fixed. Specifically, a flexible band is provided on the handle of the sub-scope. The flexible band comprises a free end and a fixed end. The flexible band surrounds the tapered transition section of the imaging catheter of the mother scope and is then buckled on the handle of the sub-scope, so as to keep the relative fixation of the mother scope and the sub-scope by the friction between the flexible band and the tapered transition section.
[0006] However, in the conventional way, the operation of the flexible band is complex. The flexible band needs to be first unbuckled and then tightly fixed around the tapered transition section of the imaging catheter of the mother scope, which means that the free end of the flexible band is wrapped around the tapered transition section of the imaging catheter once and then buckled with the fixed end. The operation is relatively complex and cannot be operated with one hand. In addition, in order to make the friction large enough, the length of the flexible band is usually smaller than the diameter of the tapered transition section, and a large pulling force is needed to forcibly stretch the flexible band to tightly fit the tapered transition section, so as to provide a large fastening force.
[0007] In summary, it is an urgent problem to provide a simple and easy-to-operate sub-scope and mother scope connecting structure. SUMMARY

[0034] The utility model will be further described in detail in combination with the drawings. These drawings are all simplified schematic views, and only schematically show the basic structure of the utility model, and thus only show the relevant components of the utility model.
[0035] In order to realize simple connection between the endoscope child mirror and the endoscope parent mirror, the present scheme provides the following examples. Example 1
[0036] Referring to Figure 1 , Figure 1 is a structural schematic view of the endoscope connecting device, which comprises a first joint part 1, a second joint part 2 and a locking mechanism 3. The first housing 11 in the first joint part 1 is connected with the endoscope child mirror (not shown in the drawing), and the second housing 12 in the first joint part 1 is used for slidingly sleeving the handle of the endoscope parent mirror (not shown in the drawing). The connecting sleeve 21 in the second joint part 2 is located in the second housing 12, and the handle of the endoscope parent mirror can be sleeved in the connecting sleeve 21. The first housing 11 and the second housing 12 are designed in one piece, for example, integrally injection molded.
[0037] The locking mechanism 3 comprises a support frame 31 composed of two protrusions 311 extending outward from the second housing 12 and oppositely arranged, an eccentric cam 33 provided between the two protrusions 311 through a rotating shaft 32, and a push rod 34 provided in the rotating direction of the eccentric cam 33. In this way, the eccentric cam 33 can be rotated between the two protrusions 311 by pushing the push rod 34.
[0038] The master endoscope can be a colonoscope or a gastroscope. Taking a duodenoscope as the master endoscope as an example, the endoscope itself can be a cholangioscope. During the procedure, the surgeon first inserts the imaging catheter of the duodenoscope into the body's natural cavities to take pictures or videos, allowing the surgeon to observe whether there are any lesions (such as digestive tract polyps or early digestive tract cancers) within the body's natural cavities. If the surgeon needs to further explore the narrower bile ducts (such as the intestines or esophagus) for lesions, or if minimally invasive surgery is required, the imaging catheter of the cholangioscope is inserted into the forceps port of the duodenoscope. The cholangioscope's imaging catheter then enters the bile duct for stone removal or biopsy. Because both the master and endoscopes need to be manipulated simultaneously, the endoscope is usually bound to the master endoscope or fixed in another way for easy one-handed operation.
[0039] During the surgery, to reduce the difficulty of operation, the endoscope connecting device in Embodiment 1 can be pre-connected to the cholangioscope through the first housing 11. When the cholangioscope is needed later, the endoscope connecting device can be connected to the endoscope mother (e.g., duodenoscope) through the second connecting part 2. Specifically, when the connecting sleeve 21 is fitted onto the handle of the endoscope mother, a first connection state is formed between the connecting sleeve 21 and the endoscope mother handle. By further manipulating the locking mechanism 3, the first connection state can be switched to the second connection state, thereby quickly and effectively cooperating with the duodenoscope. This allows the surgeon to hold the duodenoscope and cholangioscope with one hand, making it convenient for the surgeon to operate the cholangioscope for surgery.
[0040] like Figure 2 As shown, Figure 2 This is a partial cross-sectional view of the endoscope connection device in the first connection state. In the figure, the second housing 12 has a through hole 121 at the protrusion 311. An elastic pad 4 is provided in the through hole 121. The elastic pad 4 is located between the eccentric cam 33 and the connecting sleeve 21. The left side of the eccentric cam 33 is set as the first flat surface 331, and the right side of the elastic pad 4 is set as the second flat surface 41. The first flat surface 331 of the eccentric cam 33 and the second flat surface 41 of the elastic pad 4 are in contact. Due to factors such as manufacturing process errors, a near fit is also acceptable. It is only necessary to avoid the eccentric cam 33 from rotating too easily, which would cause the first connection state to be unstable. In the solution provided in this embodiment, in the first connection state, the lever 34 is roughly in a vertically upward state. In another embodiment not shown, the elastic pad 4 can also be part of the connecting sleeve 21, that is, the elastic pad 4 and the connecting sleeve 21 are integrally molded. With this configuration, the elastic pad 4 can serve as an assembly reference during the manufacturing process. By inserting the elastic pad 4 into the through hole 121, the assembly between the connecting sleeve 21 and the second housing 12 is completed, simplifying the manufacturing process.
[0041] Since the eccentric cam 33 and the elastic pad 4 are in plane contact in the first connection state, the stability of the first connection state is ensured, that is, the eccentric cam 33 will not rotate without additional applied force.
[0042] As shown in Figure 3 , Figure 3 is a partial cross-sectional view of the endoscope connecting device in the second connection state. When it is necessary to connect the endoscope child scope with the endoscope parent scope, the endoscope child scope is first connected with the endoscope connecting device, and then the connecting sleeve 21 is at least partially sleeved with the handle of the endoscope parent scope, and the knob 34 is turned clockwise, so that the eccentric cam 33 in Figure 2 is turned clockwise by a certain angle, and is switched to the second connection state shown in Figure 3 . In the process of switching from the first connection state to the second connection state, the elastic pad 4 moves to the left under the driving of the rotating eccentric cam 33, and since the elastic pad 4 is in plane contact with the connecting sleeve 21, the connecting sleeve 21 is partially deformed to the left, and a greater fastening force is applied to the handle of the endoscope parent scope, so as to achieve the purpose of fixedly connecting the endoscope parent scope with the endoscope child scope.
[0043] The endoscope connecting device of embodiment 1 can also realize quick switching between the first connection state and the second connection state. The operator only needs to perform an upward lifting or downward pressing action to realize the adjustment of the connection strength of the endoscope parent scope and the endoscope child scope. Compared with the first connection state, in the second connection state, the second connecting part 2 applies a greater fastening force to the handle of the endoscope parent scope, so that the connection strength of the endoscope parent scope and the endoscope child scope is higher, and the operator is provided with more stable operating hardware conditions during the operation.
[0044] The size of the eccentric cam 33 can be determined based on actual design needs. When the size of the eccentric cam 33 is determined, the maximum stroke of the eccentric cam 33 is also fixed, and the maximum abutting force applied to the elastic pad 4 is also established. In this way, the damage of the endoscope parent scope caused by excessive locking force can be avoided, and the safety is higher.
[0045] In summary, when it is necessary to connect and fix the endoscope child scope with the endoscope parent scope during the operation, the endoscope child scope is first connected with the endoscope connecting device, and then the connecting sleeve 21 is at least partially sleeved with the handle of the endoscope parent scope, and the knob 34 is turned, so as to realize the simple and quick connection of the endoscope parent scope and the endoscope child scope.
[0046] In some possible implementations, the first housing 11 in the first joint 1 is non-detachably connected to the handle of the endoscope, that is, the first housing 11 can be part of the handle housing of the endoscope. This configuration further reduces the surgeon's operation process and operation time during the actual operation, and reduces the patient's waiting time.
[0047] In this embodiment, the first housing 11 and the endoscope are not detachable, ensuring the firmness of their connection and the accuracy of their fit. When the endoscope is needed during the use of the endoscope mother, since the endoscope is already detachably connected to the endoscope connecting device in this embodiment, it is not necessary to connect the endoscope to the first housing 11. Only the handle of the endoscope mother needs to be connected to the connecting sleeve 21, simplifying the connection between the endoscope and the endoscope mother.
[0048] Figure 4 This is a cross-sectional view of the eccentric cam 33 in Embodiment 1. The left side of the eccentric cam 33 is the first flat surface 331. The shortest distance from the first flat surface 331 to the rotation center 332 of the eccentric cam 33 is L1. The bottom of the eccentric cam 33 is an arc-shaped working surface 333. Along the counterclockwise direction, the distance L2 from the working surface 333 to the rotation center 332 gradually increases, and L1 is less than L2. In this way, when the elastic pad 4 contacts the working surface 331 at different positions, the deformation of the elastic pad 4 is inconsistent, thereby adjusting the magnitude of the force applied by the connecting sleeve 21 to the endoscope master handle. Example 2
[0049] In embodiment 1, the first flat surface 331 of the eccentric cam 33 is in contact with the second flat surface 41 of the elastic pad 4 to ensure the stability of the connecting device in the first connection state; however, when the connecting device is in the second connection state, such as Figure 3 As shown, the lever 34 is roughly horizontal, with the right end of the lever 34 far from the connecting sleeve 21. If the lever 34 is accidentally touched during the operator's operation, causing the lever 34 to rotate, it may even cause the endoscope mother to detach from the connecting sleeve 21, making it impossible to ensure a fixed connection between the endoscope mother and the endoscope. To solve the above problems, this application provides Embodiment 2.
[0050] Example 2 is largely the same in structure as Example 1, except for the design of the eccentric cam 33;
[0051] like Figure 5The diagram shows the endoscope connection device of Embodiment 2 in its first connection state. A fixing block 35 is positioned upwards on the left side of the eccentric cam 33. The left side of the fixing block 35 has a third flat surface 351, and the right side of the elastic pad 4 has a second flat surface 41. The second flat surface 41 of the elastic pad 4 and the third flat surface 351 of the fixing block 35 are in surface contact, ensuring the stability of the eccentric cam 33 in the first connection state. A lever 34 extends outwards from the right side of the eccentric cam 33. The angle between the lever 34 and the extending direction of the fixing block 35 can be set to 90°, and the length of the lever 34 is greater than the length of the fixing block 35.
[0052] like Figure 6 The image shown is a partial cross-sectional view of the endoscope connection device in the second connection state in Embodiment 2. Figure 5 The lever 34 in the middle is rotated clockwise by a certain angle to form Figure 6 The second connection state is shown; at this time, the fixing block 35 is set horizontally to the right, and the lever 34 is set horizontally downward; in this way, the free end of the lever 34 is closer to the connecting sleeve 21. Since the length of the lever 34 is greater than the length of the fixing block 35, the fixing block 35 does not protrude from the first housing 1. This design can better prevent the endoscope connection device from accidentally touching the lever 34 during the operation, and ensure the stability of the endoscope mother and endoscope endoscope in the second connection state.
[0053] In some possible implementations, such as Figure 8 As shown, the elastic pad 4 is no longer provided on the right side of the connecting sleeve 21, and the eccentric cam 33 directly abuts against the connecting sleeve 21. This can reduce the production cost of this device, but does not affect the purpose of fixing the endoscope and the endoscope mother to each other.
[0054] Figure 7 This is a cross-sectional view of the eccentric cam 33 in Embodiment 2. Figure 7 The top of the eccentric cam 33 has an upwardly extending fixing block 35. The left side of the fixing block 35 is a third flat surface 351. The shortest distance from the third flat surface 351 to the rotation center 332 of the eccentric cam 33 is L1. The lower part of the eccentric cam 33 is an arc-shaped working surface 333. Along the counterclockwise direction, the distance L2 from the working surface 333 to the rotation center 332 gradually increases, and L1 is less than L2. In this way, when the elastic pad 4 contacts the working surface 331 at different positions, the deformation of the elastic pad 4 is inconsistent, which can adjust the magnitude of the force applied by the connecting sleeve 21 to the endoscope handle. Example 3
[0055] In the embodiment 1, the flat surface of the eccentric cam 33 is attached to the flat surface of the elastic pad 4, which ensures the stability of the connecting device in the first connection state; but in some cases, it may still be accidentally touched (for example, during transportation), resulting in the need to reset the push rod 34 when the endoscope mother lens needs to be used; in order to further improve the stability of the endoscope connecting device of the present application in the first connection state, as shown in Figure 9 、 10 , 11, the present application discloses the embodiment 3.
[0056] In the embodiment 2, the second flat surface 41 of the elastic pad 4 is in surface contact with the third flat surface 351 of the fixed block 35 to ensure the stability of this state; but in some scenarios, for example, during transportation, the push rod 34 may still be accidentally touched, resulting in the need to reset the push rod 34 when the device is connected with the endoscope mother lens; in order to solve the above problems, the present application discloses the embodiment 3.
[0057] The structure of the embodiment 3 is basically the same as that of the embodiment 2, the difference lies in the design of the second housing 12.
[0058] As shown in Figure 9 , it is a structural schematic diagram of the endoscope connecting device, in which the second housing 12 is provided with a clamping jaw 122 above the through hole 121, and the fixed block 35 and the push rod 34 are outwardly extended from the eccentric cam 33. It can be understood that the width of the free end of the fixed block 35 is slightly larger than the slot width of the clamping jaw 122, so that the clamping jaw 122 can relatively firmly clamp the free end of the fixed block 35, thereby making the endoscope connecting device in the embodiment more stably in the first connection state.
[0059] As shown in Figure 10 , it is a partial sectional view of the endoscope connecting device in the first connection state in the embodiment 3, in which the fixed block 35 is upwardly arranged, the positioning protrusions on the fixed block 35 cooperate with the clamping jaw 122, the push rod 34 is horizontally arranged to the right, and the included angle between the extension directions of the fixed block 35 and the push rod 34 is 90°.
[0060] As shown in Figure 12 、 Figure 13 , the fixed block 35 is provided with positioning protrusions 351 on the top of both sides, the positioning protrusions 351 cooperate with the clamping jaw 122 to fix the fixed block 35 and the second housing 12, and limit the rotation of the eccentric cam 33. Specifically, the clamping jaw 122 is provided with two limiting protrusions 123, the distance between the ends of the two limiting protrusions 123 away from the second housing 12 is less than the distance between the two positioning protrusions 351, and the distance between the ends of the two limiting protrusions 123 close to the second housing 12 is greater than or equal to the distance between the two positioning protrusions 351. In summary, the clamping connection between the fixed block 35 and the second housing 12 is achieved.
[0061] like Figure 11 The image shown is a partial cross-sectional view of the endoscope connection device in the second connection state in Embodiment 3. Figure 10 The lever 34 in the middle rotates clockwise to move the angle to form Figure 11 The second connection state is shown; the elastic pad 4 moves to the left under the drive of the rotating eccentric cam 33, forcing the connecting sleeve 21 to apply a greater tightening force to the handle of the endoscope mother, thus fixing the device to the endoscope mother. At this time, the lever 34 is set downward, the fixing block 35 has been disengaged from the clamp 122 and is set to the right. At this time, the endoscope mother and the device are connected in the second connection state.
[0062] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
