Description

A front end assembly and an endoscope TECHNICAL FIELD

[0001] The present application relates to the technical field of endoscopes, in particular to a front end assembly and an endoscope. BACKGROUND

[0002] Endoscopes are commonly used for examination and surgery of digestive tracts, respiratory tracts, and urogenital systems, and different types of endoscopes are required for different application scenarios, such as gastroscopes and enteroscopes for digestive systems, bronchoscopes for respiratory systems, and cystoscopes for urogenital systems. In some cases, a biopsy forceps is inserted into the human body through the instrument channel of an endoscope to obtain a target tissue sample of a lesion, so as to achieve the purpose of treatment or sampling.

[0003] However, the biopsy forceps at the present stage are all separate instruments, which need to be inserted into the instrument channel of an endoscope after the channel of the endoscope is established, and then used for sampling, which makes the operation of the biopsy forceps by a doctor more complex and leads to more troublesome sampling. SUMMARY

[0004] The present application aims to design a front end assembly and an endoscope to solve the problem of troublesome sample acquisition.

[0005] The present application is implemented by the following technical solutions:

[0006] The present application provides a front end assembly, which comprises a front end seat, a forceps cup, a camera, and an actuating rod. The distal end of the front end seat is provided with a distal end face. Two forceps cups are provided, and the two forceps cups are hingedly connected to the front end seat in opposition to each other. The two forceps cups can swing under the constraint of the hinge joints of the forceps cups and the front end seat to make a closing action and an opening action in the front region of the distal end face. The camera is connected to the front end seat, and the camera is located outside the two forceps cups. The lens of the camera faces the front region of the distal end face for photographing a lesion and the forceps cups. The actuating rod is connected to the front end seat in an axially movable manner relative to the front end seat. The distal end of the actuating rod is connected to the forceps cups for driving the two forceps cups to make the closing action and the opening action.

[0007] The present application also provides an endoscope, which comprises an insertion part. The insertion part comprises the above-mentioned front end assembly arranged at the distal end.

[0008] The present application has the following advantages and beneficial effects:

[0009] The front end assembly fuses the sampling function and the camera shooting function together on the front end seat which is used as a whole, and the functions are matched with each other. When a doctor uses the endoscope equipped with the front end assembly to perform an examination, the doctor can directly perform a sampling operation under the assistance of the camera head after finding a lesion, without needing to separately make the sampling forceps enter through the instrument channel of the endoscope to perform sampling, which simplifies the sampling operation of the doctor, makes the sampling process simple and easy, and can save operation time.

[0010] The front end assembly has both the sampling and camera shooting functions, and thus in the case of only needing to use the forceps cup to sample, the endoscope carrying the instrument channel does not need to enter the natural cavity of the human body, and thus the size of the insertion part of the endoscope not carrying the instrument channel is smaller, so that the sampling process can be performed in a more narrow space, to greatly facilitate the doctor to perform the sampling operation in the narrow space.

[0031] In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described in detail below. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments.

[0032] In one aspect, the present application provides a front end assembly 100 which can simplify sampling operation, as shown in FIGS. 1-9, and is particularly configured as follows:

[0033] The front end assembly 100 of the present embodiment is shown in FIG. 1, and includes a front end base 11 and forceps cups 12, a camera 13 and an actuating rod 15 mounted on the front end base 11. Through reciprocating movement of the actuating rod 15 relative to the front end base 11, the two forceps cups 12 can be driven to perform opening and closing action by reverse deflection, thereby achieving clamping of a target tissue sample. One function of the camera 13 is to capture an image of the tissue sample clamped by the forceps cups 12.

[0034] The state of the front end assembly 100 shown in FIG. 1 is an open forceps state, and the state of the front end assembly 100 shown in FIG. 7 is a closed forceps state.

[0035] As shown in FIG. 2, the front end base 11 has a distal end face 111 at the distal end, a proximal end face at the proximal end, and an outer peripheral face surrounding the distal end face 111 and the proximal end face, which define the overall shape of the front end base 11. The distal end face 111 of the front end base 11 is a substantially flat end face perpendicular to the axis. The distal end face 111 is provided with a hinge portion for hingedly connecting the forceps cups 12.

[0036] The distal end and the proximal end are defined based on the distance from the physician when the endoscope is used, along the length direction of the endoscope or in other words the axial direction. This applies to the assembly including the front end assembly 100, the insertion portion, the operation portion, and the constituent parts of the assembly.

[0037] As shown in FIG. 2, the two forceps cups 12 are oppositely arranged relative to each other and concave inwardly, so that when the two forceps cups 12 are closed, an internal space with an open tail end and a closed head end is formed between the two forceps cups 12. The two forceps cups 12 are hingedly connected to the front end base 11, and can be deflected in the front region of the distal end face 111 under the constraint of the hinged connection points of the two forceps cups 12 and the front end base 11. When the two forceps cups 12 are controlled to be deflected in opposite directions, the two forceps cups 12 can be closed and opened.

[0038] For example, the tail end of the forceps cup 12 is hingedly connected to the hinged part provided on the distal end of the front end base 11 by a pin shaft. For example, the body part of the forceps cup 12 between the tail end and the head end is hingedly connected to the hinged part provided on the distal end of the front end base 11 by a pin shaft. The hinged part can be arranged on the circumferential side of the front end base 11 or on the distal end face 111.

[0039] The camera 13 is fixedly connected to the front end base 11 and used for shooting images in front of the front end assembly 100. The camera 13 is located outside the two forceps cups 12, that is, the camera 13 is outside the forceps cups 12 regardless of whether the two forceps cups 12 are closed or opened. The lens of the camera 13 faces the front region of the distal end face 111 and can shoot images of the lesion and the forceps cups 12.

[0040] For example, the front end base 11 is provided with a camera module mounting hole 115 penetrating from the distal end face 111 to the proximal end face. The camera 13 is integrally inserted and fixed in the camera module mounting hole 115, and the distal end of the camera 13 can protrude from the distal end face 111, be flush with the distal end face 111, or be recessed below the distal end face 111. For example, the camera 13 is directly fixed on the distal end face 111, and the wire harness and / or circuit board thereof pass through the wire hole penetrating from the distal end face 111 to the proximal end face provided on the front end base 11. The camera 13 can be fixed by applying glue between the camera 13 and the front end base 11 or by injection molding.

[0041] The actuating rod 15 is a rigid member and can transmit axial thrust. The actuating rod 15 is movably connected to the front end base 11 and can move axially relative to the front end base 11. The distal end of the actuating rod 15 is connected to the two forceps cups 12, respectively. During the axial movement of the actuating rod 15, the two forceps cups 12 can be driven to synchronously perform opposite deflection movements, so as to realize the closing and opening actions of the two forceps cups 12.

[0042] For example, the actuating rod 15 can be provided as two, and the two actuating rods 15 are connected to the two forceps cups 12, respectively. By simultaneously controlling the synchronous movement of the two actuating rods 15, the two forceps cups 12 can be driven to synchronously perform opposite deflection movements, so as to realize the closing and opening actions of the two forceps cups 12. For example, the actuating rod 15 can be provided as one, and the one actuating rod 15 is connected to the two forceps cups 12, respectively. The two forceps cups 12 are linked to realize synchronous opposite deflection, so as to realize the closing and opening actions of the two forceps cups 12.

[0043] The front end assembly 100 of the present embodiment integrates the sampling function and the imaging function together in the front end base 11 which is used as a whole, and the two functions cooperate with each other. When a doctor uses the endoscope equipped with the front end assembly 100 to perform an examination, the doctor can directly perform a sampling operation with the assistance of the camera 13 after finding a lesion, and does not need to separately make the sampling forceps enter the body through the instrument channel of the endoscope to perform sampling, which simplifies the sampling operation of the doctor, makes the sampling process simple and easy, and can save the operation time.

[0044] The front end assembly 100 of the present embodiment has both the sampling and the imaging functions, and thus in the case of only needing to use the forceps cup 12 to sample, the endoscope carrying the instrument channel does not need to enter the natural cavity of the body. As shown in FIG. 4, in some embodiments, the front end base 11 is not provided with the channel hole 113 shown in FIGS. 1-3, so that the front end assembly 100 does not have the function of introducing instruments. In this way, the size of the insertion part of the endoscope not carrying the instrument channel can be made as small as possible, so that the sampling process can be performed in a smaller space, greatly facilitating the sampling operation of the doctor in a small space.

[0045] According to some optional embodiments, the two forceps cups 12 of the front end assembly 100 are controlled by an actuating rod 15. As shown in FIGS. 1 and 2, the front end assembly 100 is provided with two connecting rods 14, and the same side positions of the tail ends of the two forceps cups 12 are respectively hingedly connected with the distal ends of one connecting rod 14 through a pin shaft, and the proximal ends of the two connecting rods 14 are coaxially hingedly connected with the distal end of the actuating rod 15 through a pin shaft. The hinged connection points of the distal ends of the connecting rods 14 and the forceps cups 12 are located on the outside or the inside of the hinged connection points of the forceps cups 12 and the front end base 11.

[0046] For example, the hinged connection points of the distal ends of the connecting rods 14 and the forceps cups 12 are located on the side away from the camera 13.

[0047] In the present embodiment, the distal end of the actuating rod 15 hingedly connects the proximal ends of the two connecting rods 14 at the same point, and the distal ends of the two connecting rods 14 respectively hingedly connect the tail ends of the same side of the two forceps cups 12, so that the two forceps cups 12 can be driven to move together through the actuating rod 15, the space occupied by the front end assembly 100 can be reduced, and the sampling operation of the doctor is facilitated.

[0048] According to some optional embodiments, as shown in FIG. 2, the front end base 11 is provided with a through hole 112 extending from the distal end face 111 of the front end base 11 to the proximal end face in the axial direction, penetrating the front end base 11. As shown in FIGS. 1 and 5, the actuating rod 15 is arranged in the through hole 112 and can move back and forth in the axial direction. The distal end of the actuating rod 15 penetrates the through hole 112 and is connected with the tail ends of the forceps cups 12. In some embodiments, the distal end of the actuating rod 15 penetrates the through hole 112 and is hingedly connected with the proximal ends of the two connecting rods 14.

[0049] The through hole 112 can be arranged on the inner side of the two forceps cups 12 or on the outer side of the two forceps cups 12.

[0050] In this embodiment, the actuating rod 15 is arranged in the through hole 112 in the inner side of the front end seat 11, which provides better restriction to the movement of the actuating rod 15, so that the movement of the actuating rod 15 is more stable.

[0051] According to some optional embodiments, as shown in FIG. 1, FIG. 3 and FIG. 6, the actuating rod 15 is arranged on the outer side of the two forceps cups 12, and the arrangement route of the actuating rod 15 is perpendicular to the arrangement route of the two forceps cups 12, so that the actuating rod 15 is arranged compactly on the front end seat 11.

[0052] According to some optional embodiments, as shown in FIG. 2, FIG. 5 and FIG. 6, the front end seat 11 is provided with a protrusion on each of the opposite sides of the distal end face 111, which extends axially to the front and serves as a support 114 for directly hingedly connecting with the forceps cup 12.

[0053] For example, the support 114 is provided with a pin hole, the tail end of the forceps cup 12 is provided with a groove, the opposite side walls of the groove are provided with pin holes, the support 114 is inserted into the groove, the pin holes of the support 114 are aligned with the pin holes of the forceps cup 12, and a pin shaft is arranged through the pin holes, so that the forceps cup 12 is hingedly connected to the corresponding support 114. For example, the support 114 is fixedly provided with a pin shaft, the tail end of the forceps cup 12 is provided with a groove, the opposite side walls of the groove are provided with pin holes, the support 114 is inserted into the groove, and the pin shaft is inserted into the pin hole of the corresponding side, so that the forceps cup 12 is hingedly connected to the corresponding support 114.

[0054] According to some optional embodiments, the camera 13 is arranged between the two forceps cups 12, so that the camera 13 can observe not only the image of one forceps cup 12, but also the images of the two forceps cups 12 and the images between the two forceps cups 12, which can observe more useful details during the sampling operation and facilitate the doctor to make a judgment.

[0055] For example, the camera 13 is inclined to one of the two forceps cups 12. For example, as shown in FIG. 3 and FIG. 4, the camera 13 is arranged between the two forceps cups 12, so that the two forceps cups 12 are arranged symmetrically about the camera 13, which can observe the images of the two forceps cups 12 evenly and can observe more images between the two forceps cups 12, which can observe more useful details during the sampling operation through the camera 13 and facilitate the doctor to make a judgment. Preferably, the camera 13 is arranged on the latter side.

[0056] According to some optional embodiments, as shown in FIGS. 5-8, the tail end of the forceps cup 12 is kept a distance from the distal end face 111, so that an axial gap 17 is formed between the forceps cup 12 and the distal end face 111. FIGS. 5 and 6 show the gap 17 when the two forceps cups 12 are in the open state, and FIGS. 7 and 8 show the gap 17 when the two forceps cups 12 are in the closed state.

[0057] When the two forceps cups 12 are in the closed state, the axial size of the gap 17 is such that part of the inner side between the two forceps cups 12 is exposed within the shooting range of the camera 13, so that the camera 13 can shoot part of the image inside the forceps cup 12 through the tail end of the forceps cup 12, to help the doctor make a judgment.

[0058] In some embodiments, the support 114 provided on the distal end face 111 of the front end seat 11 lifts the forceps cup 12 away from the distal end face 111, so as to form the gap 17. In some embodiments, the tail end of the forceps cup 12 is provided with a protruding ear seat, which is hinged to the circumferential side of the front end seat 11. The axial length of the ear seat is relatively long, and the root of the ear seat connecting to the main body of the forceps cup 12 is located in front of the distal end face 111, so as to lift the main body of the forceps cup 12, so as to form the gap 17.

[0059] According to some optional embodiments, when the two forceps cups 12 are in the closed state, a gap 18 is formed between the two forceps cups 12. The gap 18 is caused by the fact that when the two forceps cups 12 are closed, the forceps closing faces 121 of the two forceps cups 12 do not completely contact and close, leaving an uncontacted part. The gap 18 exposes part of the inner side between the two forceps cups 12 within the shooting range of the camera 13, so that the camera 13 can shoot part of the image inside the forceps cup 12 from the part between the two forceps cups 12, to help the doctor make a judgment.

[0060] For example, when the two forceps cups 12 are closed, their forceps closing faces 121 contact and close at the head end and at the tail end, and a gap 18 is formed between the body part between the head end and the tail end. For example, as shown in FIGS. 7-9, when the two forceps cups 12 are closed, their forceps closing faces 121 only contact and close at the head end, forming a gap 18 extending from the tail end to the head end.

[0061] Preferably, the width of the gap 18 gradually decreases from the tail end to the head end of the forceps cup 12, which can ensure the closing effect of the two forceps cups 12 while providing the camera 13 with a good shooting range inside the two forceps cups 12.

[0062] Preferably, the gap 18 exposes the contact face at the head end of the two forceps cups 12 within the shooting range of the camera 13, so that the camera 13 can shoot the image of the head end part where the forceps closing faces 121 contact through the part between the two forceps cups 12, allowing the doctor to more intuitively judge the sampling degree of the tissue sample.

[0063] To expose the contact surface at the head end of the two forceps cups 12 to the shooting range of the camera 13 by the gap 18, any one or more combinations of the width and / or shape of the gap 18, the axial size of the gap 17, the distance of the camera 13 from the forceps cup 12, and the inclination angle of the camera 13 can be used.

[0064] According to some optional embodiments, as shown in FIGS. 7 and 8, when the two forceps cups 12 are closed, a gap 17 is formed between the forceps cup 12 and the distal end face 111 of the front end seat 11. The gap 17 is present when the two forceps cups 12 are closed and when the two forceps cups 12 are open, as shown in FIG. 5.

[0065] According to some optional embodiments, as shown in FIG. 9, the front end seat 11 includes a forceps cup mounting portion 11a arranged radially and a camera mounting portion 11b. The forceps cup 12 is hinged to the forceps cup mounting portion 11a, and the camera 13 is connected to the camera mounting portion 11b. The diameter of the forceps cup mounting portion 11a is greater than the diameter of the camera mounting portion 11b, and the forceps cup mounting portion 11a and the camera mounting portion 11b are smoothly transitioned, so that the end face profile of the front end seat 11 is similar to a water droplet shape, the profile size of the front end seat 11 can be reduced, and good passability is obtained.

[0066] According to some optional embodiments, as shown in FIGS. 1 and 9, the front end assembly 100 is provided with an illuminating lamp 16, which is an LED lamp. The illuminating lamp 16 is connected to the front end seat 11 and located beside the camera 13.

[0067] For example, two illuminating lamps 16 are provided, which are symmetrically arranged about the camera 13 on both sides of the camera 13. Of course, three or more illuminating lamps 16 can be provided, which can be arranged around the camera 13 or symmetrically about the camera 13.

[0068] In some embodiments, the illuminating lamp 16 is mounted in the camera module mounting hole 115.

[0069] According to some optional embodiments, as shown in FIGS. 1-3, the front end seat 11 is provided with a passage hole 113 extending along the axial direction of the front end seat 11 from the distal end face 111 to the proximal end face, penetrating the front end seat 11, and used for passing instruments and / or fluids. In use, the passage hole 113 is provided at the distal end of the insertion portion. The passage hole 113 is centrally located between the two forceps cups 12 and on the inner side of the two forceps cups 12.

[0070] The passage hole 113 is used for passing instruments and / or fluids, and is matched with the instrument channel carried by the insertion portion.

[0071] In this embodiment, after the passage hole 113 is arranged in the front end seat 11, the front end assembly 100 can be used for sampling while retaining the function of other instruments, so that the instruments inserted through the instrument channel can pass through the passage hole 113 to reach the lesion, thereby providing the possibility of using two instruments to complete the relevant operation based on one front end assembly 100, and enriching the use function of the endoscope.

[0072] According to some optional embodiments, as shown in FIG. 4, the front end seat 11 is not provided with the passage hole 113 shown in FIGS. 1-3, so that the front end assembly 100 does not have the function of introducing instruments. The front end assembly 100 of this embodiment has the functions of sampling and image shooting, and cannot introduce other instruments. Such a front end assembly 100, without the passage hole 113, can be made as small as possible in size, so that the front end assembly 100 can more easily pass through a narrower cavity and enter a narrower space. In the case of only needing to use the forceps cup 12 for sampling, the endoscope carrying the instrument channel can be used to enter the natural cavity of the human body with the front end assembly 100, thereby greatly facilitating the sampling operation of the doctor in a narrow space.

[0073] On the other hand, the present application provides an endoscope, which is particularly provided with the following arrangement structure:

[0074] The endoscope of this embodiment includes an insertion part, which includes the front end assembly 100 of any of the above embodiments arranged at the distal end. The proximal end of the front end assembly 100 is connected with a snake bone or a guide wire or a tube.

[0075] The insertion part of the endoscope of this embodiment is provided with the front end assembly 100 of any of the above embodiments, which integrates the sampling function and the image shooting function on the front end seat 11 used as a whole, and cooperates with each other. When the doctor uses the endoscope for examination and finds a lesion, the doctor can directly perform the sampling operation under the assistance of the image shooting head 13, without the need to separately insert the sampling forceps through the instrument channel of the endoscope for sampling, which simplifies the sampling operation of the doctor, makes the sampling process simple and easy, and can save the operation time.

[0076] Moreover, the direction of the insertion part of the endoscope and the direction of the forceps head do not need to be separately operated during sampling, which not only reduces the operation steps, but also makes the follow-up of the forceps head very good, thereby improving the operation efficiency and making the direction accuracy better.

[0077] According to some optional embodiments, the endoscope further comprises an operation part, a push rod for driving the traction wheel and a traction wheel for pulling the traction rope are arranged on the operation part. A driving part is further arranged on the operation part, the proximal end of the insertion part is connected to the operation part, the proximal end of the actuating rod 15 extends into the operation part and is connected to the driving part, and the doctor can push and pull the actuating rod 15 by pushing or rotating the driving part, so that the actuating rod 15 drives the two forceps cups 12 to close or open.

[0078] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which shall be covered within the protection scope of the present application.
