Description

Technical Field

[0001] This invention relates to the field of endoscopes, and more particularly to an endoscope lens mount and an endoscope having therein. Background Technology

[0002] An endoscopic ultrasound (EUS) is an electronic endoscope with ultrasound diagnostic and therapeutic functions. It includes a probe and corresponding surgical instruments. A lifter is typically mounted on the endpiece of the endoscope to adjust the angle of the instruments, allowing for targeted diagnosis and treatment of lesions. As a medical device that comes into direct contact with body cavities and fluids, EUS requires rigorous cleaning and disinfection. Incomplete cleaning and disinfection, where the exposed parts of the endoscope are not fully covered, can leave behind human tissue, bacteria, or viruses, posing a significant risk of cross-infection between different patients.

[0003] In existing ultrasonic endoscopes, the forceps lifter is typically supported in a groove in the headstock via a rotating shaft. A control rod is located on the other side of the rotating shaft, which drives the rotating shaft via a control cable, thus rotating the forceps lifter. Because the rotating shaft rotates within the groove to drive the forceps lifter, a certain clearance must be maintained between the rotating shaft and the headstock, typically 0.1mm-0.3mm on each side. During endoscope use, dirt can easily enter this gap. Due to the small gap, once dirt enters, it cannot be flushed out, severely affecting the cleaning and disinfection effectiveness of the endoscope. Summary of the Invention

[0004] The purpose of this invention is to provide an endoscope lens mount and an endoscope having the same, in order to solve the above-mentioned problems.

[0005] To achieve one of the above-mentioned objectives, the present invention provides an endoscope mount, comprising a mount body, a lifting clamp, and a rotating mechanism rotatably connected to the lifting clamp on the mount body. The mount body is provided with a receiving groove for accommodating the lifting clamp. The rotating mechanism includes a rotating groove with its open end communicating with the receiving groove, and a rotating shaft rotatably connected within the rotating groove. The rotating shaft includes a first segment located within the receiving groove and a second segment connected to the first segment and located within the rotating groove. The lifting clamp is connected to the first segment. The second segment includes a support segment with a diameter equal to the inner diameter of the rotating groove. The endoscope mount also includes a first flushing channel penetrating through the mount body, the first flushing channel communicating with the rotating groove corresponding to the position of the support segment.

[0006] As a further improvement of the present invention, one side of the support segment is connected to the first segment, and the second segment further includes a sealing segment connected to the side of the support segment away from the first segment. The diameter of the sealing segment is smaller than the diameter of the support segment, and the sealing segment is fitted with a sealing ring.

[0007] As a further improvement of the present invention, the endoscope mount further includes a flushing groove that extends through the support section along the axial direction of the support section, and the flushing groove is in communication with the first flushing channel.

[0008] As a further improvement of the present invention, the rinsing groove is formed by recessing from the surface of the support section inward.

[0009] As a further improvement of the present invention, there are multiple rinsing grooves, and the multiple rinsing grooves are evenly distributed along the circumference of the support section.

[0010] As a further improvement of the present invention, the circumference of the support segment is alternately provided with arc surfaces and planes, the distance of the arc surface from the center of the support segment is the same as the inner diameter of the rotating groove, the distance of the plane from the center of the support segment is less than the distance of the arc surface from the center of the support segment, and the rinsing groove is the plane.

[0011] As a further improvement of the present invention, the rotating groove includes a first rotating groove and a second rotating groove arranged opposite to each other along the axial direction of the rotating shaft. The support section is located in the first rotating groove, and the second section further includes a connecting section and a sealing section located in the second rotating groove. The first section connects the support section and the connecting section. The sealing section is connected to the side of the connecting section away from the first section. The diameter of the connecting section is larger than the diameter of the sealing section. The sealing section is fitted with a sealing ring. The outer peripheral surface of the connecting section has a predetermined distance from the inner wall of the second rotating groove.

[0012] As a further improvement of the present invention, a first arc surface and a first plane are alternately arranged on the circumference of the support segment. The distance between the first arc surface and the center of the support segment is the same as the inner diameter of the first rotating groove. The distance between the first plane and the center of the support segment is less than the distance between the first arc surface and the center of the support segment. The first plane extends at least to the opening end of the first rotating groove along the axial direction of the support segment.

[0013] As a further improvement of the present invention, the first segment includes a mating segment connected to the lifting clamp, the circumference of the mating segment is provided with a second arc surface connected to the first arc surface and a second plane connected to the first plane, and the lifting clamp is provided with a mating hole that mates with the second arc surface and the second plane.

[0014] The present invention provides an endoscope, the endoscope comprising the endoscope lens mount described in any of the above technical solutions.

[0015] This invention features a first rinsing channel that runs through the base of the endoscope lens mount and is connected to a rotating groove corresponding to the support section. When cleaning and disinfecting the endoscope lens mount, disinfectant enters the gap between the support section and the rotating groove through the first rinsing channel, thereby promptly rinsing out dirt from the endoscope lens mount, preventing the accumulation of dirt, ensuring the disinfection effect of the endoscope lens mount, and avoiding the risk of cross-infection between test subjects.

[0025] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0026] It should be understood that terms such as "upper," "lower," "inner," and "front," used herein to indicate spatial relative position, are for illustrative purposes to describe the relationship of one component or feature relative to another component or feature as shown in the accompanying drawings. The terms "spatial relative position" may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0027] The present invention provides an endoscope, which includes an endoscope lens mount 100 and uses an ultrasonic probe 20 disposed on the endoscope lens mount 100 to perform internal examinations of the human body.

[0028] Specifically, please refer to Figures 1 to 9 As shown, the endoscope mount 100 includes a base 1, a lifting clamp 2, and a rotating mechanism that rotatably connects the lifting clamp 2 to the base 1. The base 1 is provided with a receiving groove 3 for accommodating the lifting clamp 2. Specifically, the receiving groove 3 is connected to the outside, which can be understood as the external environment where the endoscope mount 100 is located. When the endoscope is used in a scenario, the receiving groove 3 is connected to the internal environment of the human body.

[0029] Further, the rotating mechanism includes a rotating groove 4 and a rotating shaft 5 rotatably connected within the rotating groove 4, wherein one side of the rotating groove 4 has an open end, and the open end communicates with the receiving groove 3. Further, the rotating shaft 5 includes a first section 51 located within the receiving groove 3 and a second section 52 connected to the first section 51 and located within the rotating groove 4. The lifting clamp 2 is connected to the first section 51. The second section 52 includes a support section 521 with a diameter equal to the inner diameter of the rotating groove 4. The endoscope mount 100 also includes a first flushing channel 6 penetrating the mount 1, and the first flushing channel 6 communicates with the rotating groove 4 corresponding to the position of the support section 521. The present invention provides a first rinsing channel 6 through the seat 1 of the endoscope lens holder 100, and the first rinsing channel 6 is connected to the rotating groove 4 corresponding to the position of the support section 521. When cleaning and disinfecting the endoscope lens holder 100, the disinfectant enters the gap formed by the support section 521 and the rotating groove 4 through the first rinsing channel 6, thereby rinsing out the dirt in the gap in time, avoiding the accumulation of dirt, ensuring the disinfection effect of the endoscope lens holder 100, and avoiding the risk of cross-infection between subjects.

[0030] In this invention, there can be one or more rotating grooves 4. The portion of the rotating shaft 5 located within each rotating groove 4 is the second segment 52, but there is only one support segment 521. The specific rotating groove 4 that the support segment 521 mates with can be adjusted according to the specific structure. Specifically, the diameter of the support segment 521 is the same as the inner diameter of the rotating groove 4, ensuring that the rotating shaft 5 is supported within the base 1. At the same time, there is a tolerance clearance between the support segment 521 and the rotating groove 4, allowing the rotating shaft 5 to rotate normally within the rotating groove 4. The lifting forceps 2 is circumferentially limited and connected to the first segment 51 of the rotating shaft 5. When the rotating shaft 5 rotates, the lifting forceps 2 rotates synchronously with the rotating shaft 5, thereby adjusting the position of the lifting forceps 2 and adjusting the angle of the surgical instruments through the lifting forceps 2 to achieve corresponding diagnosis and treatment of the lesion site.

[0031] Specifically, the rotation of the rotating shaft 5 can be driven by setting an adjustment mechanism. The adjustment mechanism can adopt the adjustment structure of existing endoscopes. In addition, in the endoscope of the present invention, other structures connected to the endoscope lens end mount 100 also adopt existing technologies, which will not be described in detail here.

[0032] Specifically, the first rinsing channel 6 can be a rinsing through hole that runs through the seat body 1. It is known that at least one end of the rinsing through hole is connected to the outside. When it is necessary to clean and disinfect the endpiece 100 of the endoscope, the disinfectant is manually injected into the seat body 1 through the rinsing through hole, so that the disinfectant flows through the gap between the support section 521 and the rotating groove 4. After rinsing the dirt, the disinfectant flows out of the seat body 1 through the rinsing through hole. By increasing the rinsing time of the disinfectant, a better cleaning and disinfection effect can be achieved.

[0033] In the first embodiment of the present invention, see Figures 3 to 5 As shown, one side of the support section 521 is connected to the first section 51. The second section 52 also includes a sealing section 522 connected to the side of the support section 521 away from the first section 51. The diameter of the sealing section 522 is smaller than the diameter of the support section 521. The sealing section 522 is fitted with a sealing ring 7, which abuts against the inner wall of the rotating groove 4. By forming a sealing structure with the rotating groove 4 through the sealing ring 7 in the sealing section 522, dirt entering the gap between the support section 521 and the rotating groove 4 is isolated to the side of the sealing ring 7 near the support section 521, preventing dirt from entering the interior of the seat 1. Furthermore, during cleaning and disinfection, the disinfectant can enter the gap formed by the support section 521 and the rotating groove 4, as well as the space on the side of the sealing ring 7 near the support section 521, through the first rinsing channel 6 of the endoscope lens seat 100 of the present invention, cleaning all the dirt inside the endoscope lens seat 100, preventing dirt accumulation, ensuring the disinfection effect of the endoscope lens seat 100, and avoiding the risk of cross-infection between test subjects.

[0034] Furthermore, the endoscope lens holder 100 also includes a rinsing groove 8 that extends through the support section 521 along its axial direction. During cleaning and disinfection of the endoscope lens holder 100, the rinsing groove 8 is formed, allowing the disinfectant to simultaneously enter the gap between the support section 521 and the rotating groove 4, as well as the space near the support section 521 of the sealing ring 7, through both the first rinsing channel 6 and the second rinsing channel (rinsing groove 8). This enables simultaneous cleaning of residual dirt inside the endoscope lens holder 100 via two paths, ensuring the disinfection effect of the endoscope lens holder 100 and avoiding the risk of cross-infection between test subjects, while also improving the efficiency of cleaning and disinfection of the endoscope lens holder 100.

[0035] Furthermore, the rinsing groove 8 is formed by recessing inward from the surface of the support section 521, reducing the processing difficulty and cost of the rinsing groove 8. Of course, it is understood that the setting of the rinsing groove 8 is not limited to this, and the shape of the groove is not restricted.

[0036] Furthermore, there are multiple rinsing tanks 8, which are evenly distributed around the circumference of the support section 521 to further ensure the disinfection effect of the endoscope lens mount 100 and avoid the risk of cross-infection between test subjects; at the same time, it improves the efficiency of cleaning and disinfecting the endoscope lens mount 100.

[0037] Specifically, see Figure 5 As shown, the circumference of the support segment 521 is alternately provided with arc surfaces 5211 and planes 5212. The distance between the arc surface 5211 and the center of the support segment 521 is the same as the inner diameter of the rotating groove 4. The distance between the plane 5212 and the center of the support segment 521 is less than the distance between the arc surface 5211 and the center of the support segment 521. The rinsing groove 8 is the plane 5212. This invention uses the arc surface 5211 to ensure that the diameter of the support segment 521 is the same as the inner diameter of the rotating groove 4, ensuring that the rotating shaft 5 is supported within the seat 1. The plane 5212 forms a larger rinsing groove 8, which facilitates rinsing away dirt remaining in the gap between the support segment 521 and the rotating groove 4. Furthermore, the rinsing groove 8 of the plane 5212 is easier to manufacture and process, reducing the manufacturing cost of the endoscope. In the first embodiment of this invention, there are four arc surfaces 5211 and four planes 5212. Of course, it can be understood that the number of arc surfaces 5211 and four planes 5212 provided on the support segment 521 is not limited.

[0038] The second embodiment of the present invention also includes a first flushing channel 6 communicating with the rotating groove 4 corresponding to the position of the support section 521. The difference between the second and first embodiments is the structure of the rotating groove 4 and the rotating shaft 5. The first embodiment has only one rotating groove 4, while the second embodiment has two rotating grooves 4. Specifically, in the second embodiment, see... Figure 7 , Figure 8 As shown, the rotating groove 4 includes a first rotating groove 41 and a second rotating groove 42 arranged opposite to each other along the axial direction of the rotating shaft 5. The support section 521 is located in the first rotating groove 41. The second section 52 further includes a connecting section 523 and a sealing section 522 located in the second rotating groove 42. The first section 51 connects the support section 521 and the connecting section 523. The sealing section 522 is connected to the side of the connecting section 523 away from the first section 51. The diameter of the connecting section 523 is larger than the diameter of the sealing section 522. The sealing section 522 is fitted with a sealing ring 7. The outer peripheral surface of the connecting section 523 has a predetermined distance from the inner wall of the second rotating groove 42. This creates a second rinsing channel between the connecting section 523 and the second rotating groove 42, allowing disinfectant to directly enter and exit. The second rinsing channel promptly cleans any residual dirt on the side of the sealing ring 7 near the connecting section 523. Since the seat 1 is also provided with a first rinsing channel 6 that communicates with the first rotating groove 41 corresponding to the position of the support section 521, the first rinsing channel 6 washes away any residual dirt in the gap between the support section 521 and the first rotating groove 41. In the second embodiment of the present invention, the endoscope endplate 100, through the combined action of the first rinsing channel 6 and the second rinsing channel, further ensures the disinfection effect inside the endoscope endplate 100 and avoids the risk of cross-infection between test subjects.

[0039] Furthermore, participation Figure 9 As shown, a first arc surface 9 and a first plane 10 are alternately arranged on the circumference of the support segment 521. The distance between the first arc surface 9 and the center of the support segment 521 is the same as the inner diameter of the first rotating groove 41. The distance between the first plane 10 and the center of the support segment 521 is less than the distance between the first arc surface 9 and the center of the support segment 521. The first plane 10 extends at least to the opening end of the first rotating groove 41 along the axial direction of the support segment 521. The first arc surface 9 ensures that the diameter of the support segment 521 is the same as the inner diameter of the first rotating groove 41, ensuring that the rotating shaft 5 is supported in the seat body 1. A third rinsing channel 13 is formed by the first plane 10 and the inner wall of the first rotating groove 41. The third rinsing channel 13 and the first rinsing channel 6 work together to rinse the dirt remaining in the gap between the support segment 521 and the first rotating groove 41.

[0040] Furthermore, the first segment 51 includes a mating segment 511 connected to the forceps lifter 2. The circumference of the mating segment 511 is provided with a second arc surface 11 connected to the first arc surface 9 and a second plane 12 connected to the first plane 10. The forceps lifter 2 is provided with a mating hole, which includes an arc surface segment and a plane segment that respectively mate with the second arc surface 11 and the second plane 12. By mating with the mating segment 511 through the mating hole, the forceps lifter 2 is connected to the first segment 51 of the rotating shaft 5. The operator controls the rotation direction of the rotating shaft 5 to drive the forceps lifter 2 to rotate, thereby adjusting the angle of the surgical instruments and enabling corresponding diagnosis and treatment of the lesion site.

[0041] Specifically, the second arc surface 11 can be formed by extending the first arc surface 9 along the axial direction of the rotating shaft 5, and the second plane 12 is also formed by extending the first plane 10 along the axial direction of the rotating shaft 5. It can be considered that the mating section 511 and the support section 521 are integrated. This structure reduces the processing difficulty of the rotating shaft 5, that is, reduces the processing cost of the endoscope.

[0042] The present invention provides a first rinsing channel 6 through the seat 1 of the endoscope lens holder 100, and the first rinsing channel 6 is connected to the rotating groove 4 corresponding to the position of the support section 521. When cleaning and disinfecting the endoscope lens holder 100, the disinfectant enters the gap formed by the support section 521 and the rotating groove 4 through the first rinsing channel 6, thereby promptly rinsing out the dirt inside the endoscope lens holder 100, avoiding the accumulation of dirt, ensuring the disinfection effect of the endoscope lens holder 100, and avoiding the risk of cross-infection between test subjects.

[0043] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0044] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. All equivalent embodiments or modifications made without departing from the spirit of the present invention should be included within the scope of protection of the present invention.
