Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an endoscope system. Background Technology

[0002] An endoscope is a widely used diagnostic instrument in the medical industry.

[0003] An endoscope typically includes an endoscope handle for gripping, with an insertion section at the front and a cable at the rear. The insertion section is usually a thin, flexible tube that can enter the stomach through the mouth or other natural orifices. The insertion section can integrate optical fibers, traction wires, water channels, air channels, instrument channels, etc., to achieve multiple functions. The cable can be used to connect to peripheral devices such as computers to achieve communication and control of the endoscope.

[0004] One of the solutions involves using a disposable endoscope handle that must be discarded after use. However, in the existing solution, the cable at the rear end of the endoscope handle is tightly bound to the handle and cannot be detached. Therefore, the cable must be discarded along with the endoscope handle each time it is discarded.

[0005] In other words, the cables of existing endoscopes are tightly bound to the endoscope handle and cannot be reused, resulting in high usage costs. Utility Model Content

[0078] To better understand the above technical solutions, exemplary embodiments of this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0079] Please combine Figure 1 , Figure 2 An endoscope system includes an endoscope handle and an endoscope cable 100. The two ends of the endoscope cable 100 are a terminal connection end 101 and a handle connection end 102, respectively. The terminal connection end 101 is used to connect to peripheral equipment, and the handle connection end 102 is used to connect to the endoscope handle. The endoscope handle includes a handle housing 10, a first terminal 20, and an adapter ring 30. The handle housing 10 has an insertion portion at a first end along a first direction X, and a second opening 12 at a second end. The first terminal 20 is fixedly installed at the second end of the handle housing 10. The adapter ring 30 is installed in the second opening 12, and the adapter ring 30 is hollow along the first direction X and circumferentially surrounds the first terminal 20.

[0080] The handle connection end 102 includes an adapter post 1021 for mating with the adapter ring 30, and a second terminal 1022 located at the end of the adapter post 1021. The second terminal 1022 is used to insert into the first terminal 20 along a first direction X, so that the endoscope handle is electrically connected to the endoscope cable 100. Furthermore, the adapter ring 30 has a first mounting structure, and the adapter post 1021 has a second mounting structure. The first mounting structure and the second mounting structure are configured as follows:

[0081] When the adapter ring 30 is installed with the adapter post 1021, the second mounting structure locks the first terminal 20 and the second terminal 1022 by locking it to the first mounting structure, and the second mounting structure unlocks the first terminal 20 and the second terminal 1022 by unlocking it to the first mounting structure, so that the handle connection end 102 is detachably connected to the endoscope handle.

[0082] Overall, this embodiment achieves a detachable connection between the endoscope handle and the endoscope cable by setting a first mounting structure and a second mounting structure on the endoscope handle and the endoscope cable respectively, thereby enabling the reuse of the endoscope cable.

[0083] Specifically, the endoscope handle includes a handle housing for gripping during operation.

[0084] Along the first direction, one end of the handle housing (i.e., the first end mentioned above) is provided with an insertion part. It is understood that the insertion part can enter the body through an insertion tube 97, etc. The insertion tube can specifically integrate optical fiber, traction wire, water channel, air channel, instrument channel, etc., to achieve multiple functions. The other end of the handle housing (i.e., the second end mentioned above) is provided with a second opening, wherein a first terminal and an adapter ring are provided at the second opening. The adapter ring is fixedly installed in the second opening, for example, and the first terminal is soldered to a circuit board, for example. Furthermore, the adapter ring circumferentially surrounds the first terminal, and the adapter ring is, for example, in the shape of a cylinder extending along the first direction.

[0085] Specifically, the endoscope cable has an adapter post at the handle connection end, which can be installed by mating with the aforementioned adapter ring in the first direction, and the end of the adapter post has a second terminal.

[0086] It is understandable that after the adapter post and adapter ring are installed together, the first terminal and the second terminal can be plugged in and connected.

[0087] In this embodiment, a first mounting structure is provided on the adapter ring and a second mounting structure is provided on the adapter post. The two mounting structures can be locked and unlocked after the adapter post and the adapter ring are installed together, thereby realizing the detachable connection between the handle connection end and the endoscope handle.

[0088] In other words, for example, when the adapter ring and the adapter post are first installed together, the second mounting structure can be locked to the first mounting structure, thereby locking the two terminals. Secondly, after the second mounting structure is unlocked, it can be unlocked to the first mounting structure, thereby unlocking the two terminals.

[0089] It is understood that the two mounting structures mentioned above are respectively set on the adapter ring and the adapter post. In this embodiment, the adapter ring and the adapter post serve as the carriers of the two mounting structures and the two terminals. The structure is simple, and the specific structural form of the mounting structure and the specific unlocking operation can be determined according to actual needs. For example, the unlocking operation can be a pressing method, a pushing and pulling method, or a rotating method, etc.

[0090] Regarding the two mounting structures mentioned above, in one possible implementation, the second mounting structure includes a locking spring 51 and an unlocking sleeve 52. The locking spring 51 is disposed on the circumferential wall of the adapter post 1021 and protrudes relative to the circumferential wall. The unlocking sleeve 52 is fitted over the adapter post 1021. The unlocking sleeve 52 is configured to drive the locking spring 51 to retract radially inward relative to the circumferential wall of the adapter post 1021 when it is subjected to an external force along the first direction X. The first mounting structure includes a first locking groove 41, which is disposed on the inner wall of the adapter ring 30. The first locking groove 41 is used to lock the locking spring 51.

[0091] Combination Figure 3 , Figure 4 That is, this embodiment provides one possible structural form of the two mounting structures mentioned above. The two mounting structures in this embodiment can be specifically implemented by means of snap rings and snap slots.

[0092] Specifically, the second mounting structure includes a locking spring on the circumferential wall of the adapter post, and the first mounting structure includes a first locking groove on the inner wall of the adapter ring. When the adapter post is inserted into the adapter ring in the first direction, the locking spring protruding relative to the adapter post can be engaged in the first locking groove, thereby locking the two mounting structures, that is, locking the insertion of the two terminals.

[0093] During unlocking, the unlocking sleeve can be pulled or pushed along the first direction. The unlocking sleeve can drive the locking spring to retract radially inward relative to the adapter post, thereby unlocking the two mounting structures, that is, unlocking the connection of the two terminals. At this time, it can be understood that the unlocking operation in this embodiment corresponds to pulling or pushing the unlocking sleeve.

[0094] In one specific embodiment, the second mounting structure further includes a guide boss 53, which is disposed on the circumferential wall of the adapter post 1021 and protrudes from the circumferential wall. The first mounting structure further includes a guide groove 42, which is disposed on the inner wall of the adapter ring 30. The guide boss 53 extends along the first direction X, and the guide groove 42 extends from the end of the adapter ring 30 along the first direction X.

[0095] That is, in order to achieve alignment of the two terminals when the adapter post and the adapter ring are inserted along the first direction, this embodiment can provide a guide boss on the adapter post and a guide groove on the adapter ring. The guide boss and the guide groove extend along the first direction, and the guide groove needs to extend inward from the end of the adapter ring. Thus, it can be understood that by providing the guide boss and the guide groove, the adapter post and the adapter ring can be inserted after the two terminals are aligned.

[0096] In addition, see Figure 4 The aforementioned locking springs can be installed in pairs on both sides of the adapter post, and correspondingly, the aforementioned first locking grooves should also be installed in pairs on both sides of the adapter ring.

[0097] Regarding the two mounting structures mentioned above, in one possible implementation, the second mounting structure includes a locking spring arm 54 extending along the first direction X. The first end of the locking spring arm 54 near the second terminal 1022 is attached to the adapter post 1021, and the second end of the locking spring arm 54 away from the second terminal 1022 is arranged radially away from the adapter post 1021. The first mounting structure includes a second locking groove 43, which is disposed on the inner wall of the adapter ring 30 and extends from the end of the adapter ring 30 along the first direction X.

[0098] The locking spring arm 54 and the second locking slot 43 are configured such that when the adapter ring 30 and the adapter post 1021 are inserted and installed along the first direction X, the locking spring arm 54 is locked in the second locking slot 43, and when the second end of the locking spring arm 54 is subjected to a radially inward external force, the locking spring arm 54 is unlocked in the second locking slot 43.

[0099] Combination Figure 5 , Figure 6 That is, this embodiment provides another possible structural form of the two installation structures mentioned above. The two installation structures in this embodiment can be specifically implemented by means of spring arms and slots.

[0100] Specifically, the second mounting structure includes a locking spring arm disposed on the circumferential wall of the adapter post, the locking spring arm extending along a first direction, one end of the locking spring arm near the second terminal being attached to the adapter post, and the other end being arranged radially away from the adapter post; and it is understood that the locking spring arm has elastic deformation; the first mounting structure includes a second locking groove extending inward from the end of the adapter ring along the first direction.

[0101] When the adapter post is inserted into the adapter ring along the first direction, on the one hand, it can be understood that the locking spring arm and the second locking slot can play a guiding role to achieve alignment of the two terminals; on the other hand, the locking spring arm can be locked in the second locking slot, thereby achieving locking of the two mounting structures; furthermore, when unlocking, the second end of the locking spring arm can be pressed down radially along the adapter post, and the locking spring arm can be unlocked from the second locking slot, thereby unlocking the two mounting structures; at this time, it can be understood that the unlocking operation in this embodiment corresponds to pressing down the second end of the locking spring arm.

[0102] Regarding the two mounting structures mentioned above, in one possible implementation, the second mounting structure includes a first connector 55 located at the end of the adapter post 1021, the first connector 55 being rotatably mounted on the adapter post 1021, and a second terminal 1022 fixed to the first connector 55; wherein, the second mounting structure also includes an external thread 56 located on the adapter post 1021, and the first mounting structure includes an internal thread 44 located on the inner wall of the adapter ring 30.

[0103] Combination Figure 7 , Figure 8 That is, this embodiment provides another possible structural form of the two mounting structures mentioned above. The two mounting structures in this embodiment can be implemented by means of internal threads and external threads.

[0104] Specifically, the second mounting structure includes an external thread on the adapter post, and the first mounting structure includes an internal thread on the inner wall of the adapter ring. Thus, it can be understood that the adapter post can be screwed into the adapter ring to achieve the docking installation of the two. The unlocking operation in this embodiment corresponds to rotating the adapter post.

[0105] Furthermore, considering that the rotation of the adapter post relative to the adapter ring will affect the alignment of the two terminals, this embodiment provides a first connector at the end of the adapter post. Then, the second terminal is fixed to the first connector. The first connector is rotatably mounted on the adapter post. The first connector can be inserted into the adapter ring in a straight line with restricted rotation. In this way, the alignment of the second terminal and the first terminal can be ensured while the adapter post is screwed into the adapter ring.

[0106] Regarding the two mounting structures mentioned above, in one possible implementation, the second mounting structure includes a second connector 57 located at the end of the adapter post 1021, the second connector 57 being rotatably mounted on the adapter post 1021, and the second terminal 1022 being fixed to the second connector 57; wherein, the second mounting structure also includes a threaded snap 58 located on the adapter post 1021, and the first mounting structure includes a first stop feature 45 located on the inner wall of the adapter ring 30.

[0107] Combination Figure 9 , Figure 10 That is, this embodiment provides another possible structural form of the two installation structures mentioned above. The two installation structures in this embodiment can be specifically implemented by means of threaded snap and first stop features.

[0108] Specifically, the second mounting structure includes a threaded snap on the adapter post, and the first mounting structure includes a first stop feature on the inner wall of the adapter ring. Thus, it can be understood that the adapter post can be screwed into the adapter ring to achieve the docking installation of the two. The unlocking operation in this embodiment corresponds to rotating the adapter post.

[0109] Furthermore, similar to the above, considering that the rotation of the adapter post relative to the adapter ring will affect the alignment of the two terminals, this embodiment provides a second connector at the end of the adapter post. Then, the second terminal is fixed to the second connector. The second connector is rotatably mounted on the adapter post. The second connector can be inserted into the adapter ring in a straight line with restricted rotation. In this way, the alignment of the second terminal and the first terminal can be ensured while the adapter post is screwed into the adapter ring.

[0110] In one possible embodiment, the handle housing 10 is provided with a first opening 11 for mounting an insertion part; the insertion part includes a rotary joint 60 extending along a first direction X, and a first mounting post 61 is provided at one end of the rotary joint 60 facing the first opening 11; wherein, the first mounting post 61 is provided with a first transition boss 62, and the handle housing 10 is provided with a first transition groove 15 at the first opening 11, and the first transition boss 62 and the first transition groove 15 are arranged in an annular shape relative to the first direction X; and, the first transition groove 15 is provided with a limiting boss 16, and the circumferential surface of the first transition boss 62 is provided with a limiting groove 63 with a predetermined central angle, so that the rotary joint 60 is rotatably mounted relative to the handle housing 10 within the range of the predetermined central angle.

[0111] Combination Figures 11-13 That is, this application provides a possible structure for the handle housing and the insertion part.

[0112] The handle housing should have a first opening for the insertion part to be installed.

[0113] In this embodiment, the insertion part includes a rotary joint, which is rotatably mounted on the handle housing with the first direction as the axis of rotation.

[0114] Specifically, see Figure 13 The rotary joint has a first mounting post at one end facing the first opening, and an insertion tube can be installed at the other end; the circumferential surface of the first mounting post has a first adapter boss, and the handle housing has a first adapter groove at the first opening. The first adapter boss and the first adapter groove are arranged in a ring shape; thus, it can be understood that the rotary joint can be freely rotated and installed on the handle housing by embedding the first adapter boss into the first adapter groove.

[0115] It is understandable that by rotating the rotary joint, the insertion tube can be rotated to achieve all-round and multi-angle testing, which is convenient to use.

[0116] In addition, in some specific embodiments, a limiting boss can be provided in the first transition groove, and a limiting groove can be provided on the circumferential surface of the first transition boss. The limiting groove is set at a predetermined central angle. Thus, it can be understood that by limiting the rotation angle of the limiting boss by the limiting groove, the rotary joint can rotate freely relative to the handle housing within a predetermined central angle range, such as a predetermined central angle of 180 degrees.

[0117] In one possible implementation, the insertion part includes a fixing connector 70 extending along a first direction X, and a second mounting post 71 is provided at one end of the fixing connector 70 facing the first opening 11; wherein, the second mounting post 71 is provided with a second adapter boss 72, and the handle housing 10 is provided with a second adapter groove 17 at the first opening 11, and the second adapter boss 72 and the second adapter groove 17 extend along the first direction X to restrict the radial rotation of the fixing connector 70 relative to the handle housing 10.

[0118] Combination Figures 14-16 In this embodiment, the handle housing, in addition to the above-described structure, can also be fitted with a fixed connector to accommodate different versions.

[0119] In this embodiment, the insertion part includes a fixing connector, which is fixedly installed on the handle housing.

[0120] Specifically, the fixed connector has a second mounting post at one end facing the first opening, and the aforementioned insertion tube can be installed at the other end; the circumferential surface of the second mounting post has a second adapter boss, and correspondingly, the handle housing has a second adapter groove at the first opening. Both the second adapter boss and the second adapter groove are arranged in a straight line extending along the first direction; thus, it can be understood that the second adapter boss, by embedding into the second adapter groove, can restrict the radial rotation of the fixed connector relative to the handle housing; that is to say, the fixed connector is a non-rotatable installation on the handle housing.

[0121] In addition, see Figure 13 Considering that the handle housing can be fitted with either a rotary joint or a fixed joint as needed, the second adapter groove of the handle housing can be specifically set inside the first adapter groove. In this case, it can be understood that the length of the second mounting post of the fixed structure should usually be slightly greater than the length of the first mounting post of the rotary joint.

[0122] In one specific embodiment, the handle housing 10 includes a first outer shell 13 and a second outer shell 14 that are mated together along a second direction Y, the second direction Y being perpendicular to the first direction X; wherein, the first outer shell 13 is provided with a positioning post 18 extending along the second direction Y, the second mounting post 71 is provided with a third transition boss 73, the third transition boss 73 extends radially outward from the second mounting post 71 and is perpendicular to the second direction Y, the third transition boss 73 is provided with a positioning hole 74 for the positioning post 18 to be inserted into, so as to restrict the axial movement of the fixed joint 70 relative to the handle housing 10.

[0123] That is, in this embodiment, the axial movement of the fixed joint along the first direction can be restricted by the positioning pin and the positioning hole.

[0124] Specifically, the handle housing may include, for example, a first housing and a second housing that are mated together, wherein the mating direction is a second direction, which is perpendicular to the first direction.

[0125] Then, the first housing is provided with a positioning post extending along the second direction; the second mounting post of the fixed joint is provided with a third adapter boss perpendicular to the second direction, and the third adapter boss is inserted into the positioning post through a positioning hole. Thus, it can be understood that the positioning post can restrict the movement of the fixed joint relative to the handle housing along the first direction, thereby realizing the fixed installation of the fixed joint on the handle housing. It can be understood that the fixed installation here includes the fixation of axial movement and the fixation of circumferential rotation.

[0126] In one possible embodiment, the endoscope handle includes an insertion operation assembly 80, which is mounted on the handle housing 10. The insertion operation assembly 80 includes an operation knob 81 and a rotator 82. The rotator 82 is located inside the handle housing 10, and the operation knob 81 is located outside the handle housing 10. The operation knob 81 and the rotator 82 are rotatably connected. Furthermore, a damping ring 83 is provided between the rotator 82 and the handle housing 10, and an adjusting screw 84 is provided between the operation knob 81 and the rotator 82. The adjusting screw 84 extends along the rotation axis of the operation knob 81, so that the rotator 82 can be suspended in real time by adjusting the amount of screwing in the adjusting screw 84.

[0127] That is, this embodiment provides a specific structure of the insertion part operation component on the endoscope handle.

[0128] The insertion unit operating assembly includes a rotary mechanism located inside the handle housing and an operating knob located outside the handle housing.

[0129] The operating knob is rotatably connected to the rotating device, for example, through the second stop feature 85. That is, the rotating device can be driven to rotate by operating the operating knob. Then, the rotating device can be connected to the aforementioned insertion tube, for example, through a steel wire. The rotating device can adjust the angle of the tip of the insertion tube by rotating under the drive of the operating knob.

[0130] In one aspect, this embodiment provides a damping ring between the rotator and the handle housing. The damping ring can be made of materials such as silicone.

[0131] Then, on the other hand, this embodiment also provides an adjusting screw between the rotary device and the operating knob. The adjusting screw extends along the rotation axis of the operating knob and is screwed into the rotary device after passing through the operating knob.

[0132] At this point, it can be understood that, combined with the above-mentioned damping ring setting, the tightening force of the adjusting screw in this embodiment will press the rotator tightly against the damping ring, causing it to deform. Thus, by adjusting the screwing amount, a suitable rotational damping can be generated, enabling the rotator to hover in real time. In other words, after the external force acting on the operating knob disappears, the rotator can hover in real time.

[0133] In one possible implementation, the handle housing is equipped with a suction valve button 91, a suction port 92, an instrument inlet 93, a water inlet 95, and function buttons 96. The suction port can be connected to an external suction channel and a negative pressure pump. When the suction valve button is pressed, the suction port is open; when the button is not pressed, it springs back, achieving a self-sealing effect. The instrument inlet allows the passage of commonly used medical instruments such as holmium lasers, zebra guidewires, biopsy forceps, and stone retrieval baskets. The end cap 94 is threaded to the channel and has a built-in sealing ring. A maximum pressure of 3 atmospheres can be achieved by rotating the end cap clockwise to prevent backflow of liquid. The water inlet is a standard Luer male connector, which can be connected to an external water inlet channel and a water pump for water injection.
