Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to an endoscope body. Furthermore, this utility model also relates to an endoscope system including the aforementioned endoscope body. Background Technology
[0002] With the development of modern medical devices, endoscopes such as laparoscopes and thoracoscopes are widely used in minimally invasive surgery. To ensure the smooth progress of the surgery, the endoscope must have a clear field of view, that is, the imaging surface quality of the endoscope must be guaranteed.
[0003] However, in related technologies, endoscopes are prone to internal lens breakage and debris due to improper operation, vibration during transportation, and other environmental factors. When lens fragments or other debris enter the imaging area, they will cause poor image quality and affect the doctor's judgment.
[0004] Therefore, how to prevent debris from falling into the imaging area of the endoscope and improve imaging quality is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] In view of this, the purpose of this utility model is to provide an endoscope body that can prevent debris from falling into the imaging area of the endoscope and improve imaging quality.
[0006] Another objective of this invention is to provide an endoscope system including the aforementioned endoscope body, which can prevent debris from falling into the imaging area and achieve high imaging quality.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] An endoscope body, comprising:
[0009] first tube body;
[0010] At least two spaced-apart lenses are arranged along the axial direction of the first tube body within the first tube body;
[0011] A spacer is disposed inside the first tube and located between two adjacent lenses. The two ends of the spacer are respectively fitted onto the outer periphery of the corresponding lens, and the spacer is sealed to the lens.
[0012] Optionally, the outer periphery of the lens facing the spacer is provided with an angled first stepped surface and a first transition surface, the inner wall of the spacer is in contact with the first stepped surface, and the end face of the spacer abuts against the first transition surface.
[0013] Optionally, it also includes a fastener, which is fixed at the connection position between the spacer and the lens.
[0014] Optionally, it also includes an integral tubular component, which is sleeved around the lens and the spacer, and its two ends extend to the positions of the first step surface and the first transition surface covering the two ends of the spacer, respectively. The length of the tubular component along the axial direction of the first tube is greater than the length of the spacer.
[0015] Optionally, the tubular component is a heat shrink tubing.
[0016] Optionally, the outer periphery of the end of the lens facing the spacer is provided with an angled second step surface and a second transition surface, the inner wall of the tubular member is in contact with the second step surface, and the end face of the tubular member abuts against the second transition surface.
[0017] Optionally, the inner wall of the first tube is provided with a buffer.
[0018] Optionally, the buffer element is a buffer medium layer plated on the inner surface of the first tube.
[0019] Optionally, the outer surface of the lens is provided with a groove, and there is a gap between the groove and the first tube.
[0020] An endoscope comprising any one of the aforementioned endoscope bodies.
[0021] The endoscope body provided by this utility model has the following beneficial effects:
[0022] Since the two ends of the spacer are respectively fitted onto the outer periphery of the corresponding lens, and the spacer is sealed to the lens, it is equivalent to using the spacer to seal the space between the opposite ends of two adjacent lenses, thereby protecting the entire imaging area and preventing debris between the lens and the first tube or between the spacer and the first tube from falling into the space between the two lenses. In other words, it isolates the debris outside the imaging area, preventing debris from falling into the imaging area and thus ensuring the imaging quality.
[0023] As can be seen, this endoscope body improves the connection between the spacer and the lens, ensuring imaging quality by focusing on the connection structure between the spacer and the lens. This eliminates the need to control imaging quality by ensuring the quality of incoming materials, thus reducing the requirements for the quality of incoming materials. At the same time, it also reduces the requirements for the assembly process, reducing the number of rework caused by falling debris. In addition, it avoids the impact of falling debris caused by vibration during transportation on imaging quality.
[0024] The endoscope system provided by this utility model includes the aforementioned endoscope body and has at least the beneficial effects of the aforementioned endoscope body. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0036] The core of this invention is to provide an endoscope body that prevents debris from falling into the imaging area of the endoscope, thereby improving image quality. Another core aspect of this invention is to provide an endoscope system including the aforementioned endoscope body, which also prevents debris from falling into the imaging area and provides high image quality.
[0037] Please refer to Figure 1 Figure 2 and Figure 3 This utility model provides an endoscope body, including a first tube 1, a lens 2 and a spacer 3. The lens 2 and the spacer 3 are both disposed inside the first tube 1. There are at least two lenses 2, and all lenses 2 are spaced apart along the axial direction of the first tube 1. There are at least one spacer 3, and the spacer 3 is disposed between two adjacent lenses 2. The two ends of the spacer 3 are respectively sleeved on the outer periphery of the corresponding lens 2, and the spacer 3 is sealed to the lens 2.
[0038] It is understandable that, since the two ends of the spacer 3 are respectively fitted onto the outer periphery of the corresponding lens 2, and the spacer 3 is sealed to the lens 2, it is equivalent to using the spacer 3 to seal the space between the opposite ends of two adjacent lenses 2, thereby protecting the entire imaging area and preventing debris between the lens 2 and the first tube 1 or between the spacer 3 and the first tube 1 from falling into the space between the two lenses 2. In other words, it isolates the debris outside the imaging area, preventing debris from falling into the imaging area and thus ensuring the imaging quality.
[0039] As can be seen, this embodiment of the utility model improves the connection method between the spacer ring 3 and the lens 2, starting from the connection structure between the spacer ring 3 and the lens 2, to ensure imaging quality. It eliminates the need to control imaging quality by ensuring the quality of incoming materials, thereby reducing the quality requirements of incoming materials. At the same time, it also reduces the requirements for the assembly process and reduces the number of rework caused by falling debris. In addition, it avoids the impact of falling debris caused by vibration during transportation on imaging quality.
[0040] Further, please refer to Figure 4 and Figure 5 In some embodiments, the outer periphery of the lens 2 facing the spacer 3 is provided with an angled first step surface 21 and a first transition surface 22, the inner wall of the spacer 3 is in contact with the first step surface 21, and the end face of the spacer 3 abuts against the first transition surface 22.
[0041] In other words, this embodiment achieves a contact seal between the spacer 3 and the lens 2 by providing a stepped structure at one end of the lens 2 facing the spacer 3, forming a first stepped surface 21 and a first transition surface 22. The inner wall of the spacer 3 is fitted against the first stepped surface 21, and the end face of the spacer 3 abuts against the first transition surface 22. For example, by ensuring a tight fit between the inner wall of the spacer 3 and the first stepped surface 21, and a tight abutment between the end face of the spacer 3 and the first transition surface 22, the sealing performance between the spacer 3 and the lens 2 can be improved. Simultaneously, the abutment between the end face of the spacer 3 and the first transition surface 22 also facilitates axial positioning of the lens 2 at both ends using the spacer 3. Furthermore, by ensuring the inner wall of the spacer 3 is fitted against the first stepped surface 21, the radial dimension of the outer ring of the spacer 3 is guaranteed not to exceed the radial dimension of the outer surface of the lens 2, thus satisfying the fit between the lens 2 and the spacer 3 and the inner surface of the first tube 1, and improving the stability of the structure.
[0042] It should be noted that this embodiment does not limit the angle between the first stepped surface 21 and the first transition surface 22, as long as the inner wall of the spacer 3 fits against the first stepped surface 21 and the end face of the spacer 3 abuts against the first transition surface 22. In some embodiments, the first stepped surface 21 and the first transition surface 22 are perpendicular. That is, the first stepped surface 21 extends along the axial direction of the lens 2, and the first transition surface 22 is perpendicular to the axial direction of the lens 2.
[0043] In addition, in order to improve the reliability of the connection between the spacer 3 and the lens 2, in some embodiments, the endoscope body also includes a fixing member, which is fixed at the connection position between the spacer 3 and the lens 2 to fasten the connection position between the spacer 3 and the lens 2.
[0044] In other words, this embodiment provides a fastener at the connection between the spacer 3 and the lens 2 to secure the connection between the spacer 3 and the lens 2, making the connection between the spacer 3 and the lens 2 more stable and reliable, thus ensuring the seal between the spacer 3 and the lens 2.
[0045] It should be noted that this embodiment does not limit the specific structure of the fastener, as long as the fastener can secure the connection between the spacer 3 and the lens 2. For example, the fastener can be an adhesive layer, which can be set at one or more locations such as the first step surface 21, the first transition surface 22, and the outer periphery of the connection between the lens 2 and the spacer 3, to seal and fix the spacer 3 to the lens 2.
[0046] In other embodiments, the fastener is fitted onto the outer periphery of the connection between the spacer 3 and the lens 2. For example, the fastener can be an elastic ring or a ring with a deformation-absorbing structure. The deformation-absorbing structure can be an open structure, such as a C-shaped structure, or a foldable structure. During installation, the foldable structure can be extended by external force, allowing the fastener to be fitted onto the outer periphery of the connection between the spacer 3 and the lens 2. After the fastener is installed, the foldable structure automatically retracts and resets, thus securing the connection between the spacer 3 and the lens 2.
[0047] Furthermore, for ease of installation, please refer to... Figure 3 In some embodiments, the fastener is an integral tubular member 4 (e.g., Figure 7 As shown), the tubular member 4 is sleeved on the outer periphery of the lens 2 and the spacer 3, and the two ends of the tubular member 4 extend to the positions of the first step surface 21 and the first transition surface 22 of the lens 2 covering the two ends of the spacer 3, respectively. The length of the tubular member 4 along the axial direction of the first tube body 1 is greater than the length of the spacer 3.
[0048] In other words, this embodiment uses an integrated tubular component 4 fitted over the spacer 3 to fasten the connection between the two ends of the spacer 3 and the corresponding lens 2, avoiding the need to set two separate fasteners at the connection points between the two ends of the spacer 3 and the corresponding lens 2. This simplifies the installation process, and the integrated tubular component 4 covers the entire spacer 3, resulting in a good fastening effect and a more stable structure.
[0049] It is understandable that the structure of the integrated tubular component 4 here can be the same as the structure of the fastener described above, and will not be repeated here.
[0050] Furthermore, in some embodiments, the tubular component 4 is a heat shrink tubing. It is understood that the two ends of the heat shrink tubing are fixed to the spacer 3 and the outer periphery of the lens 2 respectively by a heat shrinking process.
[0051] In other words, when the tubular component 4 is fitted onto the outer periphery of the spacer ring 3, both ends of the tubular component 4 extend to the connection positions between the two ends of the spacer ring 3 and the corresponding lenses 2. Then, the tubular component 4 is heated by a heat source, causing it to shrink and wrap around the connection positions between the two ends of the spacer ring 3 and the corresponding lenses 2. After cooling, the heat shrink tubing is shaped to form a stable structure. In this way, the heat shrink tubing can effectively wrap around the connection positions between the two ends of the spacer ring 3 and the corresponding lenses 2, providing good protection and preventing the spacer ring 3 from falling off the lenses 2.
[0052] In addition, such as Figure 4 and Figure 5As shown, in some embodiments, the outer periphery of the end of the lens 2 facing the spacer 3 is provided with an angled second step surface 23 and a second transition surface 24, the inner wall of the tubular member 4 is in contact with the second step surface 23, and the end face of the tubular member 4 abuts against the second transition surface 24.
[0053] In other words, this embodiment achieves a sealing connection between the tubular member 4 and the lens 2 by providing a stepped structure at one end of the lens 2 facing the spacer 3, forming a second stepped surface 23 and a second transition surface 24. The inner wall of the tubular member 4 is fitted against the second stepped surface 23, and the end face of the tubular member 4 abuts against the second transition surface 24. For example, by tightly fitting the inner wall of the tubular member 4 against the second stepped surface 23 and tightly abutting the end face of the tubular member 4 against the second transition surface 24, the sealing performance between the tubular member 4 and the lens 2 is improved, thus allowing the tubular member 4 to enclose the connection points between the two ends of the spacer 3 and the corresponding lens 2. Simultaneously, the abutting of the end face of the tubular member 4 against the second transition surface 24 also facilitates axial positioning of the two ends of the tubular member 4. Furthermore, by fitting the inner wall of the tubular member 4 against the second stepped surface 23, the radial dimension of the outer ring of the tubular member 4 is ensured to not exceed the radial dimension of the outer surface of the lens 2, thus satisfying the fit between the lens 2 and the tubular member 4 and the inner surface of the first tube 1, and improving the stability of the structure. Of course, in other embodiments, the outer radial dimension of the tubular member 4 may be greater than the radial dimension of the outer surface of the lens 2, as needed.
[0054] It should be noted that this embodiment does not limit the angle between the second step surface 23 and the second transition surface 24, as long as the inner wall of the tubular member 4 fits against the second step surface 23 and the end face of the tubular member 4 abuts against the second transition surface 24. In some embodiments, the second step surface 23 and the second transition surface 24 are perpendicular. That is, the second step surface 23 extends along the axial direction of the lens 2, and the second transition surface 24 is perpendicular to the axial direction of the lens 2.
[0055] It is understood that in some embodiments, the two ends of the lens 2 are respectively provided with two-stage stepped structures to form a first stepped surface 21 and a first transition surface 22, as well as a second stepped surface 23 and a second transition surface 24. The first stepped surface 21 and the first transition surface 22 are used to cooperate with the spacer 3, and the second stepped surface 23 and the second transition surface 24 are used to cooperate with the tubular member 4, so that the lens 2 is tightly fitted with the spacer 3 and the tubular member 4 respectively.
[0056] In addition, in order to reduce the breakage of the lens 2, in some embodiments, the inner wall of the first tube 1 is provided with a cushioning element.
[0057] In other words, by providing a buffer on the inner wall of the first tube 1, this embodiment avoids direct hard contact between the lens 2 and the first tube 1, thereby reducing the impact of drops and vibrations on the lens 2, reducing the probability of the lens 2 breaking, and reducing the generation of debris.
[0058] It should be noted that this embodiment does not limit the specific structure or material of the buffer, as long as the buffer can play a buffering role and reduce the possibility of lens 2 breaking. For example, the buffer can be an elastic element or a heat shrink tubing, that is, a layer of heat shrink tubing is added inside the first tube 1 so that the heat shrink tubing is attached to the inner wall of the first tube 1.
[0059] For ease of setup, such as Figure 2 As shown, in some embodiments, the buffer is a buffer medium layer 5 plated on the inner surface of the first tube 1.
[0060] In other words, this embodiment forms an integral structure between the buffer medium layer 5 and the first tube body 1 by depositing a buffer medium layer 5 on the inner wall of the first tube body 1. This arrangement is convenient for processing and assembly. It should be noted that this embodiment does not limit the specific material of the buffer medium layer 5. For example, the buffer medium layer 5 can be a Teflon material.
[0061] In addition, in order to reduce the friction between the lens 2 and the first tube 1, in some embodiments, the outer surface of the lens 2 is provided with a groove, and there is a gap between the groove and the first tube 1.
[0062] In other words, this embodiment improves the structure of the outer surface of the lens 2 by setting a groove to reduce the mating area between the lens 2 and the inner wall of the first tube 1, thereby reducing the friction between the lens 2 and the first tube 1, and thus reducing the shedding of lens 2 debris. It should be noted that this embodiment does not specifically limit the shape, number, or distribution of the groove.
[0063] In addition, such as Figure 1 and Figure 2 As shown, in some embodiments, a second tube 6 is sleeved on the outer periphery of the first tube 1, and a third tube 7 is provided outside the second tube 6. There is a gap between the third tube 7 and the second tube 6 to form a channel for setting optical fibers between the second tube 6 and the third tube 7.
[0064] In addition to the endoscope body described above, this utility model also provides an endoscope system including the endoscope body disclosed in the above embodiments. For the structure of other parts of the endoscope system, please refer to the prior art, which will not be described in detail here.
[0065] In other words, the key point of this embodiment is that the endoscope system adopts the endoscope body disclosed in any of the above embodiments, so that the endoscope system at least includes the beneficial effects of the above endoscope body, which will not be repeated here.
[0066] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
