Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a support base, an endoscope handle, an endoscope, and a method for installing the same. Background Technology

[0002] An endoscope is a commonly used medical device that can directly enter human cavities for examination, providing doctors with comprehensive diagnostic information. An endoscope typically includes: an insertion part for insertion into the body, a handle for controlling the bending of the insertion part's tip, and a display device for showing the internal environment of the body's natural cavities. Through the coordination of these three parts, an endoscope can achieve visualization of the human body's interior, exploration of lesions, and treatment.

[0003] In related technologies, a support base is typically provided inside the handle housing to support the proximal end of the insertion part. The proximal end of the insertion part is fixedly connected to the support base with adhesive. To reliably fix the proximal end of the insertion part inside the handle housing, a sufficient amount of adhesive is usually applied to the outer periphery of the insertion part and the support base, and the outer periphery of the insertion part is fixedly connected to the support base with sufficient adhesive.

[0004] Furthermore, the handle housing is divided into an upper housing and a lower housing. To ensure the reliability of the handle housing connection, the upper and lower housings are assembled by inserting a pin into a mounting hole. However, due to the limited size of the distal end of the handle, the mounting hole is usually located close to the support base. The inventors discovered that the compact structure of the distal end of the handle housing inevitably leads to shrinkage during injection molding. This shrinkage can cause deformation of the support base and mounting hole, affecting not only the installation accuracy of the insertion part but also increasing the assembly difficulty of the upper and lower housings.

[0005] Therefore, providing an endoscope with high installation accuracy of the insertion part and easy assembly of the handle housing is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] This invention discloses a support base, an endoscope handle, an endoscope, and an installation method thereof, in order to solve the technical problems in the related art where the distal structure of the handle housing is compact, and the shrinkage problem affects the installation accuracy of the insertion part and increases the difficulty of housing assembly when the handle housing is formed by injection molding.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] The first aspect of the present invention provides a support base.

[0009] The present invention provides a support base for an endoscope handle. The support base includes a base and sidewalls. The base is located at the distal end of the handle housing. The sidewalls are located on opposite sides of the base. The sidewalls are higher than the base and form a groove between the base and the sidewalls. The groove is used to install the proximal end of the endoscope insertion part. The sidewalls are provided with notches that penetrate the sidewalls in the thickness direction.

[0010] Furthermore, the base is provided with multiple empty slots, which are spaced apart.

[0011] Furthermore, the sidewall is fixedly connected to the mounting hole of the housing, and the notch extends to the mounting hole of the housing along the thickness direction of the sidewall.

[0012] Furthermore, along the axial direction of the housing, the width of the notch is smaller than the width of the slot, so that the adhesive in the groove forms a shielding barrier at the notch.

[0013] Furthermore, the width of the notch is 0.6mm to 1.5mm along the axial direction of the handle.

[0014] Furthermore, a plurality of protrusions are formed on the inner surface of the sidewall, and the height of the protrusions on both sides of the slot gradually decreases from the base to the top of the sidewall.

[0015] Furthermore, there is a gap between the distal end of the sidewall and the adapter of the insertion part, and a stepped structure is provided on the distal end face of the sidewall, the distal corner of the sidewall is an arc-shaped structure, and the arc-shaped structure extends to the stepped structure.

[0016] A second aspect of the invention provides an endoscope handle.

[0017] The endoscope handle of the present invention includes a housing and a support base, wherein the housing has a receiving cavity, and the support base is the support base described in any of the technical solutions of the present invention, and the support base is located within the receiving cavity.

[0018] A third aspect of the invention provides an endoscope.

[0019] The endoscope of the present invention includes a handle and an insertion part, wherein the handle is an endoscope handle as described in any of the technical solutions of the present invention, the proximal end of the insertion part is mounted on a support seat inside the handle, and the proximal end of the insertion part is fixedly connected to the support seat by adhesive bonding.

[0020] A fourth aspect of the present invention provides a method for assembling an endoscope.

[0021] The assembly method of the endoscope of the present invention, based on the endoscope described in any of the technical solutions of the present invention, involves installing and fixing the distal end of the insertion portion. The assembly method includes at least the following steps:

[0022] A predetermined amount of adhesive is injected into the support base, and the proximal end of the insertion part is installed in the groove of the support base;

[0023] Observe whether the adhesive in the support is full through the notch of the support. Based on the observation results, inject adhesive into the proximal end of the insertion part and the groove, and fill the empty groove of the support with adhesive. At the same time, the adhesive in the groove forms a shielding barrier at the notch.

[0024] Inject adhesive into the notch and allow it to cure under light.

[0025] The technical solution adopted in this invention can achieve the following beneficial effects:

[0026] In a first aspect, the support base of the present invention includes a base and a side wall. A notch is provided on the side wall. When the handle housing is formed by injection molding, the notch on the side wall helps to reduce the accumulation of internal stress during the curing of the injection molding material, and also helps to release heat more evenly during the curing of the injection molding material. This reduces the possibility of deformation of the support base and the mounting hole, thereby improving the installation accuracy of the proximal end of the insertion part and ensuring the assembly of the pin with the mounting hole.

[0027] The support base of the present invention solves the technical problem in the related art that the compact layout of the distal end of the handle housing affects the installation accuracy of the insertion part and increases the difficulty of housing assembly due to shrinkage during the injection molding process when the handle housing is formed. This is achieved by setting a notch on the side wall.

[0028] Secondly, in the support base of the present invention, a notch penetrates through the sidewall in the thickness direction of the sidewall. When the support base is fixedly connected to the outer periphery of the insertion part by the adhesive, since the sidewall has a certain thickness and the adhesive has fluidity, the adhesive injected into the groove and / or the proximal end of the insertion part may flow to the notch. After the adhesive cures, it fills the notch, thereby forming a limiting structure for the adhesive at the notch. This limiting structure can limit the insertion part in the axial direction, and when the insertion part and / or the handle are subjected to axial force, the reliability of the connection between the insertion part and the support base can be enhanced.

[0029] Thirdly, the support of the present invention has a notch on the side wall, and the notch extends through the side wall in the thickness direction. Normally, the curing of the adhesive requires ultraviolet irradiation. When the adhesive is cured by ultraviolet irradiation, since the light transmittance of the adhesive is higher than that of the side wall, the notch can also allow more ultraviolet rays to irradiate the adhesive, thereby accelerating the curing rate of the adhesive and enhancing the curing effect of the adhesive.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0041] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0042] In the various embodiments of this application, "near end" and "far end" refer to the distance of each component from the user in the usage environment. The end closer to the user is designated as the "near end", and the end farther from the user is designated as the "far end".

[0043] In related technologies, the outer periphery of the insertion part is fixedly connected to the support base with sufficient adhesive. Simultaneously, the support base is connected to the mounting hole of the lower housing of the handle. The upper housing of the handle also has a pin; inserting the pin into the mounting hole connects the upper and lower housings (multiple mounting holes and pins are spaced apart along the axial direction of the housings). Due to the compact structure, during the injection molding process to form the handle housing, deformation of the support base and mounting holes may occur due to shrinkage. Deformation of the support base will affect the installation accuracy and reliability of the insertion part; the pin and mounting hole are usually interference-fitted, and if the mounting hole deforms, the pin will be unable to be inserted, increasing the assembly difficulty of the upper and lower housings.

[0044] Therefore, the support base of this application has a notch on its side wall. This notch reduces the possibility of deformation of the support base and the mounting hole, thereby improving the installation accuracy of the proximal end of the insertion part and ensuring the assembly of the pin and the mounting hole. On the other hand, when the support base and the outer periphery of the insertion part are fixedly connected by adhesive, the adhesive flowing to the notch can also form a limiting structure after curing, which can axially limit the proximal end of the insertion part and allow more ultraviolet light to irradiate the adhesive.

[0045] The following is in conjunction with the appendix Figures 1 to 8 The support base, endoscope handle, endoscope and its installation method provided in this application are described in detail through specific embodiments and application scenarios.

[0046] The first aspect of this embodiment describes the support base in detail.

[0047] The support base in this embodiment is used on the handle 200 of the endoscope. Specifically, the support base is located inside the handle 200 of the endoscope and is used to support and fix the proximal end of the insertion part 300 of the endoscope. Preferably, the proximal end of the insertion part 300 is fixedly connected to the support base by adhesive bonding.

[0048] The adhesive used in this embodiment is a UV adhesive (also known as shadowless adhesive, photosensitive adhesive, or ultraviolet curing adhesive). UV adhesive must be irradiated with ultraviolet light to cure. UV adhesive cures quickly (it can change from liquid to solid in a few seconds) and is colorless and transparent after curing, with a light transmittance of more than 90%.

[0049] The support base in this embodiment includes a base 110 and a side wall 120, such as... Figure 4 and Figure 5 As shown. Exemplarily, the base 110 and sidewall 120 are an integral structure. The base 110 is located at the distal end of the housing 210 of the handle 200, and the sidewalls 120 are located on opposite sides of the base 110. The sidewalls 120 are higher than the base 110, forming a groove 130 between the base 110 and the sidewalls 120. The groove 130 is used to install the proximal end of the endoscope insertion portion 300, such as... Figures 2-7 As shown. After the proximal end of the insertion part 300 is installed in the groove 130, the channel of the insertion part 300 communicates with the instrument channel 213 and the suction channel 214 in the housing 210, thereby allowing for instrument insertion, negative pressure suction, and other operations via the endoscope. Figure 2 and Figure 3 As shown.

[0050] Preferably, a notch 121 is provided on the side wall 120, such as... Figure 2 and Figure 5 As shown. When the handle housing is formed by injection molding, the notch 121 on the side wall 120 helps to reduce the accumulation of internal stress during the curing of the injection molding material, and also helps to release heat more evenly during the curing of the injection molding material. This reduces the possibility of deformation of the support and mounting hole 211, thereby improving the installation accuracy of the proximal end of the insertion part 300 and ensuring the assembly of the pin 215 with the mounting hole 211.

[0051] In this embodiment, the support base solves the technical problem in the related art that the compact layout of the distal structure of the handle housing affects the installation accuracy of the insertion part 300 and increases the assembly difficulty of the housing 210 due to shrinkage when the handle housing is formed by injection molding.

[0052] More preferably, in the thickness direction of the sidewall 120, the notch 121 extends through the sidewall 120, such as... Figure 2 and Figure 5 As shown. When the support base is fixedly connected to the outer periphery of the insertion part 300 by the adhesive, due to the certain thickness of the side wall 120 and the fluidity of the adhesive, the adhesive injected into the groove 130 and / or the proximal end of the insertion part 300 may flow to the notch 121. After the adhesive cures, it fills the notch 121, thereby forming a limiting structure for the adhesive at the notch 121. This limiting structure can limit the insertion part 300 in the axial direction, and when the insertion part 300 and / or the handle 200 are subjected to axial force, it can enhance the reliability of the connection between the insertion part 300 and the support base.

[0053] On the other hand, when the support base is fixedly connected to the outer periphery of the insertion part 300 by the adhesive, the adhesive in this embodiment is a UV adhesive, which requires ultraviolet light irradiation to cure. After the proximal end of the insertion part 300 is installed on the support base, the proximal end of the insertion part 300 will block ultraviolet light, thereby affecting the curing effect of the adhesive. In this embodiment, the support base has a notch 121 on the side wall 120, and the notch 121 penetrates through the side wall 120 in the thickness direction. When the adhesive is cured by ultraviolet light irradiation, since the light transmittance of the adhesive is higher than that of the side wall 120, the notch 121 can also allow more ultraviolet light to irradiate the adhesive, thereby accelerating the curing rate of the adhesive and enhancing the curing effect of the adhesive.

[0054] According to an optional embodiment, the base 110 is provided with a plurality of slots 111, which are spaced apart, such as... Figure 5 As shown. Preferably, the base 110 has 2 to 10 slots 111. For example, Figure 5 A schematic diagram is shown of a base 110 having six empty slots 111.

[0055] On the one hand, in the preferred embodiment, the support base 110 has multiple slots 111. When the handle housing is formed by injection molding, the slots 111 can further reduce the accumulation of internal stress during the curing of the injection molding material, and also help to release heat more evenly during the curing of the injection molding material, thereby further reducing the possibility of deformation of the support base and the mounting hole 211. On the other hand, when the support base is fixedly connected to the outer periphery of the insertion part 300 by adhesive, the slots 111 on the base 110 can accommodate adhesive, thereby increasing the bonding area between the adhesive and the proximal end of the insertion part 300; accommodating the adhesive in the slots 111 also prevents the adhesive injected into the groove 130 from overflowing.

[0056] In this embodiment, the support base has a notch 121 on the side wall 120. During the glue pouring process, the glue in the empty groove 111 can be observed through the notch 121 to see if it is full. If it is not full, more glue can be poured into the support base. If it is full, less glue can be poured into the support base. This not only ensures the reliability of the proximal bonding of the insertion part 300, but also avoids the problem of excessive glue overflow.

[0057] According to an optional embodiment, the sidewall 120 is fixedly connected to the mounting hole 211 of the housing 210, such as... Figure 3 and Figure 5 As shown. Preferably, the sidewall 120 is disposed close to the mounting hole 211, and the sidewall 120 and the mounting hole 211 are an integral structure. Since the size of the distal end of the housing 210 is limited, fixing the sidewall 120 to the mounting hole 211 not only makes the structural layout of the distal end of the housing 210 compact and saves space, but also improves the strength of the support and the mounting hole 211.

[0058] Preferably, the notch 121 extends to the mounting hole 211 of the housing 210 along the thickness direction of the sidewall 120. Extending the notch 121 to the mounting hole 211 of the housing 210 increases the depth of the notch 121 in the thickness direction of the sidewall 120, thereby allowing the notch 121 to accommodate more adhesive. After the adhesive cures, it further enhances the axial restraint of the insertion part 300, thereby further enhancing the reliability of the connection between the insertion part 300 and the support.

[0059] According to an optional embodiment, along the axial direction of the housing 210, the width of the notch 121 is smaller than the width of the slot 111, causing the adhesive in the groove 130 to form a barrier at the notch 121, such as... Figure 5 As shown. Preferably, the width of the notch 121 along the axial direction of the handle 200 is 0.6mm to 1.5mm. More preferably, the width of the notch 121 is 0.6mm to 1mm. For example, the width of the notch 121 is 0.6mm, 0.7mm, 0.8mm, 0.9mm, or 1mm.

[0060] like Figure 5 As described above, in the height direction of the sidewall 120, the notch 121 extends from the top of the sidewall 120 to the top of the mounting hole 211. The notch 121 in the sidewall 120 presents a possibility of adhesive leakage. To ensure a reliable connection between the handle 200 housing 210 and the pin 215, the mounting hole 211 and the pin 215 are typically interference-fitted. If adhesive overflows from the notch 121 and enters the mounting hole 211, the adhesive inside will rapidly solidify under ultraviolet light. The solidified adhesive will occupy part of the space in the mounting hole 211, resulting in excessive resistance when the pin 215 engages with the mounting hole 211. This not only makes the pin 215 susceptible to damage but also affects the reliability of the assembly of the endoscope handle 200 housing 210.

[0061] Therefore, in this preferred embodiment, the support base has a notch 121 with a width smaller than the groove 111, specifically a notch 121 width of 0.6mm to 1.5mm. This not only reduces the shrinkage rate during the curing of the injection molding compound, but also, due to the small width of the notch 121 and the viscosity and poor flowability of the adhesive, the surface tension of the adhesive can be used to connect the adhesive with the walls on both sides of the notch 121 and form a barrier. This barrier can prevent more adhesive from overflowing from the notch 121, thus preventing the adhesive from flowing out of the notch 121 and entering the mounting hole 211, which would easily damage the pin 215 and affect the assembly reliability of the endoscope handle 200 housing 210.

[0062] According to an optional embodiment, a plurality of protrusions 122 are formed on the inner surface of the sidewall 120, such as... Figure 5 As shown. For example, the protrusion 122 is formed by the connection between the base 110 and the sidewall 120, or the protrusion 122 is formed by protruding from the inner surface of the sidewall 120, such as... Figure 5 As shown. Preferably, a plurality of protrusions 122 are formed on the inner surfaces of both sidewalls 120. For example, the number of protrusions 122 on each sidewall 120 is 2 to 5, and the plurality of protrusions 122 are evenly distributed. In the preferred embodiment of this technical solution, the support base has a plurality of protrusions 122 formed on the inner surface of the sidewall 120. The protrusions 122 can increase the contact area between the support base and the adhesive, thereby enhancing the reliability of the adhesive bonding between the proximal end of the insertion part 300 and the support base.

[0063] Preferably, the protrusions 122 on both sides of the slot 111 gradually decrease in height from the base 110 to the top of the side wall 120. In this preferred embodiment, the support base has a gradually decreasing height of the protrusions 122 from the base 110 to the top of the side wall 120, which allows for a larger width of the slot 111 in the radial direction of the handle 200. This increases the volume of the slot 111, resulting in a better effect in reducing shrinkage during plastic injection molding. It also allows the slot 111 to hold more adhesive, minimizing adhesive overflow and increasing the bonding area near the insertion part 300.

[0064] like Figure 1 and Figure 2 As shown, a connector 310 is provided at the proximal end of the insertion part 300. The connector 310 has a through hole extending along its axial direction. The proximal end of the insertion part 300 is installed in the through hole and extends out. A limiting part 216 is also provided at the distal end of the housing 210. By installing the connector 310 at the distal end of the housing 210 and making the limiting part 216 abut against the connector 310, the initial installation of the proximal end of the insertion part 300 can be achieved. Figures 2-7 As shown. By abutting the limiting part 216 against the adapter 310, the adapter 310 can be limited in the radial direction.

[0065] According to an optional embodiment, a gap 140 is provided between the distal end of the sidewall 120 and the adapter 310 of the insertion portion 300, such as... Figure 2 and Figure 3 Therefore, in the preferred embodiment, the support base has a gap 140 between the distal end of the side wall 120 and the adapter 310. This gap 140 facilitates the flow of adhesive from the groove 130 to the gap, allowing the adhesive to fix the adapter 310 to the support base. This further limits the axial direction of the adapter 310, ensuring the reliability of its installation.

[0066] Preferably, a stepped structure 123 is provided on the distal end face of the sidewall 120, such as... Figure 6 and Figure 7 As shown. In this preferred embodiment, the support base has a stepped structure 123 on the far end face of the side wall 120, which can further increase the bonding area between the adhesive at the gap 140 and the side wall 120, thereby further enhancing the reliability of the connection between the adapter 310 and the support base.

[0067] More preferably, the distal corner of the sidewall 120 is an arc-shaped structure 124, which extends to the stepped structure 123, such as... Figure 6 and Figure 7As shown. In the preferred embodiment, the support base has an arc-shaped structure 124 at the far end of the side wall 120, and the arc-shaped structure 124 extends to the stepped structure 123, allowing the adhesive overflowing to the top of the side wall 120 to flow along the arc-shaped structure 124 to the stepped structure 123.

[0068] By setting the distal corner of the sidewall 120 to an arc-shaped structure 124, more adhesive can enter the gap 140, thereby enhancing the reliability of the bonding between the adapter 310 and the support. On the other hand, the adhesive overflowing to the top of the sidewall 120 is guided to the stepped structure 123 by the arc-shaped structure 124, thereby reducing the amount of adhesive overflowing to the top of the sidewall 120 entering the mounting hole 211. This further avoids the problem that the adhesive entering the mounting hole 211 will harden and cause excessive resistance when the pin 215 mates with the mounting hole 211.

[0069] The second aspect of this embodiment describes the endoscope handle in detail.

[0070] The endoscope handle of this embodiment includes a housing 210 and a support base 100. The housing 210 has a receiving cavity 212, and the support base 100 is a support base according to any technical solution in this embodiment. The support base 100 is located within the receiving cavity 212. Figure 2 As shown. Preferably, the support is located at the distal end of the receiving cavity 212, as... Figure 2 As shown.

[0071] Preferably, the support base 100 and the handle housing 210 are an integral structure, which can improve the production efficiency of the housing 210 and simplify the assembly process of the housing 210.

[0072] Preferably, the housing 210 includes a first housing 210a and a second housing 210b, which are separate structures. When the first housing 210a and the second housing 210b are closed, they form a cavity 212. Figures 2-8 As shown. The remaining structures within the cavity 212 (such as the instrument channel 213 and the suction channel 214, etc.) are the same as those in the prior art and will not be described in detail here.

[0073] More preferably, one of the first housing 210a and the second housing 210b is provided with a mounting hole 211, and the other of the first housing 210a and the second housing 210b is provided with a pin 215. By inserting the pin 215 into the mounting hole 211, the first housing 210a and the second housing 210b can be initially fixed. Figure 2 , Figure 4 , Figure 6 and Figure 8As shown. Furthermore, adhesive can be injected at the connection between the first housing 210a and the second housing 210b to achieve a sealed connection between the first housing 210a and the second housing 210b.

[0074] The endoscope handle of this embodiment has a support base according to any of the technical solutions in this embodiment. The support base can not only reduce the possibility of deformation of the support base and the mounting hole 211, thereby improving the installation accuracy of the proximal end of the insertion part 300, but also ensure the assembly of the pin 215 with the mounting hole 211. In addition, it has the advantages of enhancing the reliability of the connection between the insertion part 300 and the support base, accelerating the curing rate of the adhesive, and enhancing the curing effect of the adhesive.

[0075] The third aspect of this embodiment provides a detailed description of the endoscope.

[0076] The endoscope in this embodiment includes a handle 200 and an insertion portion 300, such as... Figure 1 As shown. The handle 200 is an endoscope handle according to any technical solution in this embodiment. The proximal end of the insertion part 300 is mounted on the support base 100 inside the handle 200, and the proximal end of the insertion part 300 and the support base 100 are fixedly connected by adhesive bonding, as shown. Figure 1 As shown.

[0077] like Figures 1-3 As shown, the proximal end of the insertion part 300 is also provided with an adapter 310. The proximal end of the insertion part 300 is installed in the adapter 310 and extends out. The distal end of the housing 210 is also provided with a limiting part 216. By installing the adapter 310 on the distal end of the housing 210 and making the limiting part 216 abut against the adapter 310, the preliminary installation of the proximal end of the insertion part 300 can be achieved.

[0078] The remaining structures of the insertion section 300 (such as the active bending section, the passive full section, the remote module, etc.) are the same as those in the prior art and will not be described in detail here.

[0079] The endoscope of this embodiment has an endoscope handle according to any of the technical solutions in this embodiment. The proximal end of the insertion part 300 is installed on the distal end of the handle 200. This not only improves the installation accuracy of the proximal end of the insertion part 300, but also ensures the assembly of the pin 215 and the mounting hole 211. Furthermore, it enhances the reliability of the connection between the insertion part 300 and the support, accelerates the curing rate of the adhesive, and enhances the curing effect of the adhesive.

[0080] The fourth aspect of this embodiment describes in detail the assembly method of the endoscope.

[0081] The assembly method of the endoscope in this embodiment is based on any of the technical solutions in this embodiment, and involves installing and fixing the distal end of the insertion part 300. This assembly method includes at least the following steps:

[0082] Step S100: Pour a preset amount of adhesive into the support base 100, and install the proximal end of the insertion part 300 into the groove 130 of the support base 100. The preset amount of adhesive is such that the adhesive in the groove 130 will not overflow from the notch 121 when the insertion part 300 is not installed.

[0083] In this embodiment, before installing the proximal end of the insertion part 300 into the groove 130, glue is pre-filled into the support base 100 to ensure that there is sufficient glue between the groove 130 and the bottom surface of the proximal end of the insertion part 300, thereby further improving the reliability of the installation of the proximal end of the insertion part 300.

[0084] Step S200: Observe whether the adhesive in the support base 100 is full through the notch 121. Based on the observation, inject adhesive into the proximal end of the insertion part 300 and the groove 130, so that the adhesive in the empty groove 111 of the support base 100 is full, and at the same time, the adhesive in the groove 130 forms a shielding barrier at the notch 121. The adhesive in the empty groove 111 is full, which means that the empty groove 111 is filled with adhesive.

[0085] When refilling the adhesive, observe whether the adhesive in the empty groove 111 is full through the notch 121. If it is not full, more adhesive can be poured into the support. If it is full, less adhesive can be poured into the support. This not only ensures the reliability of the proximal bonding of the insertion part 300, but also avoids the problem of excessive adhesive overflow.

[0086] Step S300: Inject adhesive into notch 121 and cure the adhesive by irradiation.

[0087] Because the notch 121 penetrates through the thickness of the sidewall 120, less adhesive is applied at the notch 121 during step S200. This results in a weaker barrier at the notch 121, which is detrimental to axially limiting the proximal end of the insertion part 300. In this embodiment, by re-injecting adhesive into the notch 121, the strength of the cured adhesive at the notch 121 is enhanced, thereby further improving the reliability of the proximal installation of the insertion part 300.

[0088] The endoscope assembled by the method of this embodiment has the advantages of high proximal installation accuracy and reliability of the insertion part 300, and easy assembly and high assembly accuracy of the housing 210.
