Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an endoscope connector plug-in / plug-out structure. Background Technology

[0002] Gastrointestinal endoscopes are widely used in the medical field. They consist of a long, narrow insertion end. One end is inserted into the body, while the other end is divided into a light guide, an air supply tube, and an image signal harness, which connects to the main unit. The image signal harness transmits image signals to the image processing unit on the main unit, which processes the image information and outputs the results to a display. When the operator finishes working with the electronic endoscope or changes the endoscope, they need to disconnect the light guide, air supply tube, and image signal harness. For ease of operation, these three components are integrated into a single component for insertion and removal; in this case, this component is referred to as the light guide connector. Most connectors used on endoscopes in the current market employ a snap-fit, hard-plug mechanism. This type of hard-plugging is difficult and the connector core is easily damaged by forceful insertion and removal. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide an endoscope connector insertion and removal structure that allows the female and male connectors to be inserted and removed via a rotating connection, making the screwing in and out faster and less strenuous, thereby effectively protecting the insert.

[0004] To achieve the above objectives, the present invention employs the following technical solution: a male connector embedded in a hole in the endoscope image processor panel, and a female connector mating with the male connector, characterized in that:

[0005] The male connector includes a first connecting tube extending from the end of the endoscope image processor, and a male connector fixed inside the first connecting tube; a core is provided at the outer end of the male connector; at least two first screws are provided on the outside of the first connecting tube;

[0006] The female connector includes a rotating outer shell, a first sleeve fitted inside the rotating outer shell, an inner sleeve connected to the bottom end of the first sleeve and partially extending into the first sleeve, and a second sleeve assembly disposed inside the first sleeve and fixedly connected to the inner sleeve; the outer end of the second sleeve assembly is inserted with a female socket, and the outer end of the female socket has a socket adapted to the ferrule.

[0007] At least two arc-shaped grooves are constructed from the outer end to the side wall of the first sleeve. The arc opening of the arc-shaped groove corresponds to the first screw, and the inner end of the arc-shaped groove forms a notch. A gap is formed between the outer side wall of the female seat and the inner wall of the first sleeve.

[0008] The insert is aligned with the socket, the outside of the first connecting sleeve extends into the gap, the first screw is engaged in the arc opening, the rotating outer shell is rotated and the first sleeve is rotated, and the first screw moves along the arc groove to be engaged in the recess so that the male connector and the female connector remain relatively locked.

[0009] In the above technical solution, after the male connector's insert is aligned with the female connector's socket, the female connector's socket, second sleeve assembly, and inner sleeve remain stationary relative to the male connector. Meanwhile, the female connector's rotating outer shell is fixed relative to the first sleeve. Rotating the rotating outer shell causes it and the first sleeve to rotate relative to the male connector. The first screw on the first connecting sleeve in the male connector moves along the arc groove on the first sleeve to the notch at the bottom of the groove and engages, thus locking the rotating outer shell and the first sleeve relative to the male connector. When unscrewing, the first screw moves along the arc groove to disengage from the first sleeve. Since the inner sleeve is connected to the first sleeve, a slight outward force disengages the insert from the socket, allowing for complete removal, which is more convenient and faster.

[0010] Preferably, the second sleeve assembly includes a first rotary joint and a second sleeve whose upper end extends into and is fixedly fitted into the first rotary joint; the lower part of the female seat has a protrusion extending axially, and the inner wall of the head of the second sleeve has a groove; the lower part of the female seat extends into the first rotary joint, and the protrusion and groove engage. In this technical solution, since the first rotary joint and the second sleeve are fixed by screws, the engagement of the protrusion and the groove prevents the first rotary joint and the second sleeve from rotating circumferentially relative to the female seat. It should be noted that at least one of the protrusion and the groove engages.

[0011] Preferably, an annular convex wall is constructed in the middle of the outer wall of the female seat, above the protrusion. A mating groove is formed on the lower side of the inner end of the first rotary joint. The upper end of the second sleeve abuts against the mating groove, forming an annular groove that matches the annular convex wall. In this technical solution, the cooperation between the annular convex wall and the annular groove can prevent the first rotary joint and the second sleeve from moving axially relative to the female seat, maintaining the connection stability between the female seat and the first rotary joint and the second sleeve.

[0012] Preferably, the second sleeve assembly further includes a second rotary joint fitted onto the lower part of the second sleeve, and a flange is formed on the upper part of the second sleeve. A wave-shaped spring is fitted between the second rotary joint and the flange. In this technical solution, the wave-shaped spring provides axial elastic force, thereby enabling the female seat, the first rotary joint, and the second sleeve, mainly the female seat, to perform axial position self-adjustment, which facilitates the alignment and distance control of the light guide.

[0013] Preferably, a spring connector is fixedly inserted into the lower part of the second rotary joint, and the inner cylinder is mated and fixed to the spring connector. The spring connector and the inner cylinder are respectively provided with a first spring hole, and the lower inner edge of the first sleeve is provided with a second spring hole. A torsion spring is sleeved on the inner cylinder, and the upper and lower connecting sections of the torsion spring are inserted into the second spring hole and the first spring hole, respectively. In this technical solution, after rotating the outer shell, one end of the torsion spring is positioned on the inner cylinder and remains stationary, while the other end is positioned on the first sleeve. Rotating the outer shell causes the first sleeve to rotate, compressing the torsion spring. After the female connector is pulled out, the inner cylinder and the first sleeve return to their original positions due to the elastic force of the torsion spring, facilitating the next insertion and use.

[0014] Preferably, at least two mounting grooves are symmetrically provided on the side wall of the first sleeve, and threaded holes are provided in the mounting grooves. A retaining edge is formed circumferentially at the upper end of the first sleeve, and a through hole is provided on the inner side of the retaining edge extending to the upper part of the side wall of the first sleeve and located above the mounting groove.

[0015] An axially extending and bent strip spring is fixed in the mounting groove by a second screw. The upper end of the strip spring has a vertically extending first extension section and a bent extension section at the upper part. A locking protrusion is provided on the inner side of the upper edge of the rotating housing. The second extension section is pressed into the through hole, and the first sleeve is assembled in the rotating housing. When the second extension section is released, the locking protrusion and the first extension section lock together at the top and bottom.

[0016] In the above technical solution, the second extension of the strip-shaped spring is gripped inward with a tool such as tweezers, compressing the two strip-shaped springs inward. At this point, the rotating housing is inserted from the rear of the first sleeve. When the front end of the rotating housing is on the same horizontal plane as the flange end face, the tool is released. The strip-shaped springs spring back to their initial state, and the first extension engages with the locking protrusion inside the rotating housing, fixing the rotating housing to the first sleeve and preventing axial movement of the first sleeve relative to the rotating housing. This spring-loaded method facilitates flexible installation and removal of the housing.

[0017] Preferably, the outer circumferential side of the retaining edge is provided with multiple locking slots, and the inner wall of the rotating housing is provided with multiple ribs that engage with the multiple locking slots. In this technical solution, the cooperation between the locking slots and the ribs can further lock the rotating housing and the first sleeve, preventing the first sleeve from moving circumferentially.

[0018] Preferably, the flange has at least two mating grooves to facilitate the rotation of the second screw. In this technical solution, since the second screw is used to fix the strip-shaped spring, it also rotates when the first sleeve rotates. The mating grooves facilitate the rotation of the second screw.

[0019] Preferably, the outer wall of the rotating housing is provided with multiple anti-slip grooves circumferentially. In this technical solution, the multiple anti-slip grooves make it easier for the user to rotate the rotating housing, making the rotation more comfortable.

[0020] Preferably, the male connector further includes a second connecting sleeve and a threaded fastener; the second connecting sleeve is mated and fixed to the first connecting sleeve, and the threaded fastener is snapped onto the outside of the male connector and threadedly connected to the inner wall of the first connecting sleeve; a male connector bracket is fixedly provided at the end of the second connecting sleeve, and the male connector is fixed in the endoscope image processor panel hole through the male connector bracket; a step is formed at the outer end of the first connecting sleeve, and an assembly marking point is provided on the step. In this technical solution, the male connector is firmly fixed in the first connecting sleeve by the threaded fastener, and there are first screws on both sides of the assembly marking point. In this case, there are two first screws, and the assembly marking point facilitates the user's installation of the female connector. Attached Figure Description

[0038] like Figures 1-12 The endoscope connector plug-in structure shown includes a male connector 100 embedded in the endoscope image processor panel hole 1, and a female connector 200 mating with the male connector 100. The male connector 100 includes a first connecting tube 101 extending out of the end of the endoscope image processor 300, and a male connector 102 fixed in the first connecting tube 101. A core 2 is provided at the outer end of the male connector 102. At least two first screws 3 are passed through the outside of the first connecting tube 101.

[0039] The connector female connector 200 includes a rotating outer shell 201, a first sleeve 202 fitted inside the rotating outer shell 201, an inner sleeve 203 connected to the bottom end of the first sleeve 202 and partially extending into the first sleeve 202, and a second sleeve assembly disposed inside the first sleeve 202 and fixedly connected to the inner sleeve 203; the outer end of the second sleeve assembly is inserted with a female seat 204, and the outer end of the female seat 204 has a socket 4 adapted to the ferrule 2;

[0040] At least two arc-shaped grooves 5 are constructed from the outer end of the first sleeve 202 to the side wall. The arc opening of the arc-shaped groove 5 corresponds to the first screw 3, and the inner end of the arc-shaped groove 5 forms a notch 6. A gap is formed between the outer side wall of the female seat 204 and the inner wall of the first sleeve 202.

[0041] The insert 2 is connected to the socket 4, the outside of the first connecting cylinder 101 extends into the gap, the first screw 3 is inserted into the arc mouth, the rotating outer shell 201 is rotated and the first sleeve 202 is rotated, and the first screw 3 moves along the arc groove 5 to be inserted into the recess 6 so that the male connector 100 and the female connector 200 of the connector remain relatively locked.

[0042] In the above technical solution, after the insert 2 of the male connector 102 is connected to the socket 4 of the female connector, the female seat 204, the second sleeve assembly and the inner cylinder 203 in the female connector are stationary relative to the male connector 102, while the rotating outer shell 201 in the female connector is fixed relative to the first sleeve 202. When the rotating outer shell 201 is rotated, the rotating outer shell 201 and the first sleeve 202 rotate relative to the male connector 102. The first screw 3 on the first connecting cylinder in the male connector moves along the arc groove 5 on the first sleeve to the notch at the bottom of the groove and gets stuck, so that the rotating outer shell and the first sleeve are locked relative to the male connector. When unscrewing, the first screw 3 moves along the arc groove 5 to disengage from the first sleeve. Since the inner cylinder is connected to the first sleeve, a little force is applied outward to disengage the insert from the socket and pull it out completely.

[0043] Furthermore, the second sleeve assembly includes a first rotary joint 205 and a second sleeve 206 whose upper end extends into and is fixedly fitted within the first rotary joint 205; the lower part of the female seat 204 has a protrusion 7 extending axially, and the inner wall of the head of the second sleeve 206 has a groove 8; the lower part of the female seat 204 extends into the first rotary joint 205, and the protrusion 7 and the groove 8 form a snap-fit. In this technical solution, since the first rotary joint 205 and the second sleeve 206 are fixed by screws, the engagement of the protrusion and the groove prevents the first rotary joint 205 and the second sleeve 206 from rotating circumferentially relative to the female seat 204. It should be noted that at least one of the protrusion and the groove engages.

[0044] Furthermore, an annular convex wall 9 is constructed in the middle of the outer wall of the female seat 204, above the protrusion 7. A mating groove is formed on the lower side of the inner end of the first rotary joint 205. The upper end of the second sleeve 206 abuts against the mating groove, forming an annular groove 10 that matches the annular convex wall 9. In this technical solution, the cooperation between the annular convex wall 9 and the annular groove 10 can prevent the first rotary joint 205 and the second sleeve 206 from axially moving relative to the female seat 204, maintaining the connection stability between the female seat and the first rotary joint and the second sleeve.

[0045] Furthermore, the second sleeve assembly also includes a second rotary joint 207 fitted onto the lower part of the second sleeve 206. A flange 11 is formed on the upper part of the second sleeve 206, and a wave-shaped spring piece 208 is fitted between the second rotary joint 207 and the flange 11. In this technical solution, the wave-shaped spring piece 208 provides axial elasticity, thereby enabling the female seat, the first rotary joint, and the second sleeve—primarily the female seat—to perform axial position self-adjustment, facilitating the alignment and distance control of the light guide.

[0046] Furthermore, a spring connector 209 is fixedly inserted into the lower part of the second rotary joint 207, and the inner cylinder 203 is fixedly connected to the spring connector 209. The spring connector 209 and the inner cylinder 203 are respectively provided with first spring holes 12, and the lower inner edge of the first sleeve 202 is provided with a second spring hole 13. A torsion spring 210 is sleeved on the inner cylinder 203, with its upper and lower connecting sections inserted into the second spring hole 13 and the first spring hole 12, respectively. In this technical solution, after rotating the outer shell, one end of the torsion spring 210 is positioned on the inner cylinder and remains stationary, while the other end is positioned on the first sleeve. Rotating the outer shell causes the first sleeve to rotate, compressing the torsion spring 210. After the connector female joint is pulled out, the inner cylinder and the first sleeve return to their original positions due to the elastic force of the torsion spring 210, facilitating the next insertion and use.

[0047] Furthermore, at least two mounting grooves 14 are symmetrically provided on the side wall of the first sleeve 202, and threaded holes are provided in the mounting grooves 14. A retaining edge 15 is formed circumferentially at the upper end of the first sleeve 202, and a through hole 16 is provided on the inner side of the retaining edge 15 extending to the upper part of the side wall of the first sleeve 202 and located above the mounting groove 14.

[0048] An axially extending and bent strip spring 18 is fixed in the mounting groove 14 by a second screw 17. The upper end of the strip spring 18 has a vertically extending first extension section 19 and a bent extension section 20. The upper edge of the rotating housing 201 has a locking protrusion 21. The second extension section 20 is pressed into the through hole 16. The first sleeve 202 is assembled in the rotating housing 201. When the second extension section 20 is released, the locking protrusion 21 and the first extension section 19 are locked together.

[0049] In the above technical solution, there are two strip-shaped spring pieces. Using a tool such as tweezers, the second extension 20 of the strip-shaped spring piece 18 is gripped inwards, compressing the two spring pieces inwards. At this point, the rotating outer shell is inserted from the rear side of the first sleeve. When the front end of the rotating outer shell is on the same horizontal plane as the end face of the flange, the tool is released. The strip-shaped spring piece 18 springs back to its initial state, and the first extension 19 engages with the locking protrusion 21 inside the rotating outer shell, fixing the rotating outer shell 201 to the first sleeve 202 and preventing axial movement of the first sleeve 202 relative to the rotating outer shell 201. The use of spring pieces facilitates flexible installation and removal of the outer shell.

[0050] Furthermore, the outer circumferential surface of the retaining edge 15 is provided with multiple latches 22, and the inner wall of the rotating outer shell 201 is provided with multiple ribs 23 that engage with the multiple latches 22. In this technical solution, the cooperation between the latches 22 and the ribs can further lock the rotating outer shell and the first sleeve, preventing the first sleeve from moving circumferentially.

[0051] Furthermore, at least two mating grooves 24 are provided on the flange 11 to facilitate the rotation of the second screw 17. In this technical solution, since the second screw 17 is used to fix the strip spring, the second screw also rotates when the first sleeve rotates, and the mating grooves 24 facilitate the rotation of the second screw.

[0052] Furthermore, the outer wall of the rotating housing 201 is provided with multiple anti-slip grooves 25 circumferentially. In this technical solution, the multiple anti-slip grooves facilitate the user's rotation of the rotating housing, making the rotation more comfortable.

[0053] Furthermore, the male connector 100 also includes a second connecting cylinder 103 and a threaded fastener 104; the second connecting cylinder 103 is mated and fixed to the first connecting cylinder 101, and the threaded fastener 104 is snapped onto the outside of the male connector 102 and threadedly connected to the inner wall of the first connecting cylinder 101; a male connector bracket 26 is fixedly provided at the end of the second connecting cylinder 103, and the male connector 100 is fixed in the endoscope image processor panel hole 1 through the male connector bracket 26; a step is formed at the outer end of the first connecting cylinder 101, and an assembly marking point is provided on the step. In this technical solution, the male connector is firmly fixed in the first connecting cylinder by the threaded fastener, and there are two first screws on both sides of the assembly marking point. In this case, there are two first screws, and the assembly marking point facilitates the user's installation of the female connector.

[0054] In this specific embodiment, in the use of existing endoscopes, the male and female connectors are often connected by a snap-fit ​​mechanism. Insertion and removal require a forceful insertion and removal method, which is laborious and easily damages the ferrule. In the above solution, the female connector is divided into two parts: a rotatable part and a stationary part. The rotatable part includes a rotating outer shell and a first sleeve. The first sleeve has an arc-shaped groove that can be rotatably locked to the first screw on the male connector. The stationary part mates with the male connector, allowing the rotatable part to rotate relative to it. This solution has a reasonable structural arrangement, a simple rotation method, greatly improves the ease of insertion and removal, and protects the ferrule from damage.
