Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a handle housing, a handle, and an endoscope. 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] An endoscope handle typically includes a housing and, within the housing, a rotating wheel, a wire rope, a circuit board, etc. The housing also includes an image capture button, a suction valve, a lever, and other operating components. In related technologies, the housing comprises a first housing and a second housing, both with a snap-fit ​​structure for secure connection. However, the inventors have discovered that snapping the first and second housings together carries the risk of the snap-fit ​​structure breaking, leading to low assembly efficiency and reliability.

[0004] Therefore, improving the endoscope handle housing to provide a handle housing that optimizes assembly efficiency and assembly effect is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model discloses a handle housing, a handle, and an endoscope to solve the technical problems of low assembly efficiency and low assembly reliability in the assembly of handle housings in related technologies.

[0006] To solve the above problems, the present invention adopts the following technical solution:

[0007] The first aspect of this utility model provides a handle housing.

[0008] The present invention relates to a handle housing for use in an endoscope. The handle housing includes a first housing and a second housing, which are connected to each other by a fastening structure. The fastening structure includes a slot portion and a protrusion portion. The slot portion is located on at least one of the first housing and the second housing, and the protrusion portion is located on at least the other of the first housing and the second housing. The slot portion includes a first slot portion, and the protrusion portion includes a first protrusion portion. The first slot portion located at the end of the first housing and / or the second housing is inclined, and the inclination direction of the first protrusion portion that cooperates with the first slot portion is the same as the inclination direction of the first slot portion.

[0009] A second aspect of this invention provides a handle.

[0010] The handle of this utility model includes the handle housing described in any one of the technical solutions of this utility model.

[0011] The third aspect of this utility model provides an endoscope.

[0012] The endoscope of this utility model includes the handle described in any one of the technical solutions of this utility model.

[0013] The technical solution adopted in this utility model can achieve the following beneficial effects:

[0014] In this utility model, when the first and second housings are fastened together, the end without the first slot and the first protrusion is first fixed, and then the first and / or second housings are pressed to engage the first slot and the first protrusion. During the engagement of the first slot and the first protrusion, because the first slot is tilted and the tilt direction of the first protrusion is the same as that of the first slot, this tilted arrangement allows the first protrusion to slide into the slot from the side of the first slot. This avoids the end of the first slot from abutting against the first protrusion, which would otherwise require a large deformation of the first slot to engage the first protrusion.

[0015] As can be seen, the handle housing of this utility model, through the inclined first slot and first protrusion, can reduce the risk of the first slot being easily broken and damaged, and solve the technical problem of low assembly efficiency and low assembly reliability of the handle housing in the related art. On the other hand, this structure also has the advantage of saving effort when fastening the first slot and the first protrusion, and the first protrusion can be engaged in the first slot with a small force.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] 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.

[0029] 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".

[0030] In related technologies, a first and a second housing are provided, one with protrusions on its side and proximal end, and the other with slots on its side and proximal end. When the two housings are closed, the protrusions engage with the slots, thereby achieving a fixed connection between the first and second housings. During the engagement of the first and second housings, it is usually difficult to ensure perfect alignment. Typically, the distal ends of the first and second housings are fixed first, and then the proximal ends are gradually fixed. However, since the protrusions and slots in related technologies are usually arranged vertically, this structure easily leads to the slot at the proximal end abutting against the protrusion (specifically, the end of the slot abutting against the end of the protrusion) when the first and second housings are fastened. The slot needs to undergo significant deformation to allow the protrusion to engage, resulting in the slot being easily broken or damaged.

[0031] Therefore, the handle housing of this application provides an inclined first slot and a first protrusion at the ends of the first housing and the second housing, so that the first protrusion can slide into the slot from the side of the first slot, thereby avoiding the problem of the end of the first slot abutting against the first protrusion.

[0032] The following is in conjunction with the appendix Figures 1 to 9 The present application provides a detailed description of the handle housing, handle, and endoscope through specific embodiments and application scenarios.

[0033] The first aspect of this embodiment describes the handle housing in detail.

[0034] The handle housing of this embodiment is used in endoscopes, particularly for the handle portion of an endoscope. The handle housing has an internal receiving space for accommodating structures such as rotating wheels, wire ropes, and circuit boards. Figure 1 or Figure 2 As shown, the handle housing is also equipped with operating components such as a photo button, a suction valve 170, and a lever 180. The operator can perform corresponding operations by holding the handle and controlling the operation components.

[0035] In this embodiment, the handle housing, the first housing 110 and the second housing 120, are connected to each other by a snap-fit ​​structure, such as... Figure 1 or Figure 2 As shown. This fixed connection method facilitates the installation and disassembly of the first housing 110 and the second housing 120. Furthermore, the first housing 110 and the second housing 120 are also fixedly connected by adhesive bonding. At the joint between the first housing 110 and the second housing 120, adhesive bonding enhances the reliability of the connection between the two housings and also improves the sealing performance at the joint.

[0036] In some embodiments, the fastening structure includes a slot portion 130 and a protrusion portion 140. The protrusion portion 140 is engaged within the slot portion 130, thereby enabling the fastening connection between the first housing 110 and the second housing 120.

[0037] For example, the slot portion 130 is located on the first housing 110, and correspondingly, the protrusion portion 140 is located on the second housing 120, as shown. Figure 4 and Figure 7 As shown; or the slot portion 130 is located on the second housing 120, and correspondingly, the protrusion portion 140 is located on the first housing 110; or the slot portion 130 is located on both the first housing 110 and the second housing 120, and correspondingly, the protrusion portion 140 is also located on both the first housing 110 and the second housing 120. In all the above structures, the first housing 110 and the second housing 120 are fastened together by the engagement of the protrusion portion 140 and the slot portion 130.

[0038] In some embodiments, the slot portion 130 includes a first slot portion 131, and the protrusion portion 140 includes a first protrusion portion 141, such as... Figure 2 and Figure 3 As shown. For example, when the first slot portion 131 is located on the end of the first housing 110, the first protrusion portion 141 is located on the end of the second housing 120, as... Figure 4 and Figure 7 As shown; or when the first slot portion 131 is located on the end of the second housing 120, the first protrusion portion 141 is located on the end of the first housing 110; or when the first slot portion 131 is located on the end of the first housing 110 and the second housing 120, the first protrusion portion 141 is located on the end of the first housing 110 and the second housing 120.

[0039] In this embodiment, the end of the first housing 110 can refer to the proximal sidewall of the first housing 110, or the position on the top wall of the first housing 110 near the proximal end face. Similarly, in this embodiment, the end of the second housing 120 can refer to the proximal sidewall of the second housing 120, or the position on the bottom wall of the second housing 120 near the proximal end face.

[0040] In some embodiments, the first slot portion 131 is inclined, and the inclination direction of the first protrusion portion 141 that mates with the first slot portion 131 is the same as the inclination direction of the first slot portion 131. The first slot portion 131 being inclined means that when the first housing 110 and / or the second housing 120 containing the first slot portion 131 are placed horizontally, the angle between the first slot portion 131 and the horizontal plane is less than 90° or greater than 90°; that is, the first slot portion 131 is not placed vertically (vertical direction as...). Figure 4 (As shown by the middle arrow). The tilting direction of the first protrusion 141 is the same as the tilting direction of the first slot 131. This can mean that the tilting direction of the entire first protrusion 141 is the same as the tilting direction of the first slot 131, or it can mean that the tilting direction of one surface on the first protrusion 141 is the same as the tilting direction of the first slot 131.

[0041] The inclination direction of the first protrusion 141 mentioned in this embodiment is the same as the inclination direction of the first slot 131. This can mean that the inclination angle of the first protrusion 141 is exactly the same as the inclination angle of the first slot 131; or it can mean that the inclination angle of the first protrusion 141 is different from the inclination angle of the first slot 131, but both are inclination in the same direction, such as both are inclination towards the proximal end.

[0042] In this embodiment, when the first housing 110 and the second housing 120 are fastened together, the end without the first slot portion 131 and the first protrusion portion 141 is first fixed, and then the first housing 110 and / or the second housing 120 are pressed to make the first slot portion 131 and the first protrusion portion 141 engage.

[0043] During the engagement of the first slot portion 131 and the first protrusion portion 141, since the first slot portion 131 is inclined and the inclination direction of the first protrusion portion 141 is the same as that of the first slot portion 131, this inclined arrangement of the first slot portion 131 and the first protrusion portion 141 allows the first protrusion portion 141 to slide into the slot from the side of the first slot portion 131. This avoids the end of the first slot portion 131 from abutting against the first protrusion portion 141, which would otherwise require the first slot portion 131 to undergo a large deformation in order for the first protrusion portion 141 to engage with the first slot portion 131.

[0044] As can be seen, the handle housing of this embodiment, through the inclined first slot portion 131 and the first protrusion portion 141, can reduce the problem of the first slot portion 131 being easily broken or damaged, and solve the technical problem of low assembly efficiency and assembly reliability of handle housings in related technologies. On the other hand, this structure also has the advantage of saving effort when fastening the first slot portion 131 and the first protrusion portion 141, as the first protrusion portion 141 can be engaged in the first slot portion 131 with a small amount of force.

[0045] In some embodiments, the first slot portion 131 is located at the proximal end of the first housing 110 and / or the second housing 120, such as... Figure 2 As shown. When fastening the first housing 110 and the second housing 120 together, the distal ends of the first housing 110 and the second housing 120 can be fixed first, and then the first housing 110 and / or the second housing 120 can be pressed to fix the proximal ends of the first housing 110 and the second housing 120.

[0046] In this embodiment, the handle housing has the first slot portion 131 and the first protrusion portion 141 disposed at the proximal ends of the first housing 110 and the second housing 120. During assembly, not only can the insertion portion be fixed by fixing the distal ends of the first housing 110 and the second housing 120, but it can also avoid the problem of interference between the first slot portion 131 and the first protrusion portion 141 and the insertion portion when the first slot portion 131 and the first protrusion portion 141 are disposed at the distal ends of the first housing 110 and the second housing 120.

[0047] In some embodiments, the first slot portion 131 is inclined towards the proximal end, and the first protrusion portion 141 is located on the outer side wall of the first housing 110 and / or the second housing 120, such as... Figure 4 and Figure 7 As shown. This structure facilitates the disengagement of the first slot portion 131 and the first protrusion portion 141. Specifically, applying force to the first slot portion 131 in a direction away from the first protrusion portion 141 will disengage the first slot portion 131 and the first protrusion portion 141. On the other hand, this structure also prevents the first slot portion 131 and the first protrusion portion 141 from encroaching on the internal space of the handle housing.

[0048] In some embodiments, the first slot portion 131 is inclined towards the distal end, and the first protrusion portion 141 is located on the inner sidewall of the first housing 110 and / or the second housing 120. This structure, where the first slot portion 131 and the first protrusion portion 141 are located within the internal space of the handle housing, enhances the aesthetics of the handle housing end.

[0049] In some embodiments, a first boss 151 is provided on the proximal end of the first housing 110 and / or the second housing 120, and a first slot portion 131 is provided on the first boss 151. Exemplarily, the first boss 151 may be an inclined structure, and the inclination direction of the surface of the first boss 151 is the same as the inclination direction of the first slot portion 131. Figure 6 As shown, a first boss 151 is provided on the proximal end of the first housing 110, and a first slot portion 131 is provided on the first boss 151.

[0050] Not limited to this, the first slot portion 131 may also be directly disposed on the proximal end face of the first housing 110 and / or the second housing 120.

[0051] In this embodiment, the handle housing has a first slot 131 disposed on a first boss 151. This not only allows the first slot 131 to form an inclined structure, but also enhances the strength of the near end of the first housing 110, making it less likely to be damaged when the first housing 110 and the second housing 120 are fastened together.

[0052] In some embodiments, a second boss 152 is provided on the proximal end of the first housing 110 and / or the second housing 120, and a first protrusion portion 141 is disposed on the second boss 152. Exemplarily, the second boss 152 has a slope 1521, the first protrusion portion 141 is disposed on the slope 1521, and the inclination direction of the slope 1521 is the same as the inclination direction of the first slot portion 131, such as... Figure 8 As shown. Figure 8 As shown, a second boss 152 is provided on the proximal end of the second housing 120, and a first protrusion 141 is provided on the second boss 152.

[0053] Not limited to this, the first protrusion 141 may also be directly disposed on the proximal end face of the first housing 110 and / or the second housing 120.

[0054] In this embodiment, the handle housing has a first protrusion 141 disposed on the second protrusion 152. This not only allows the first protrusion 141 to form an inclined structure, but also enhances the strength of the near end of the second housing 120, making it less likely to cause damage to the second housing 120 when the first housing 110 and the second housing 120 are fastened together.

[0055] In some embodiments, the end of the first slot portion 131 is provided with a first guide surface 1311, such as... Figure 6 As shown. For example, the first guide surface 1311 is an arc surface or a slope surface. When the first slot portion 131 abuts against the first protrusion portion 141, the first guide surface 1311 can guide the first slot portion 131 to facilitate the engagement of the first slot portion 131 and the first protrusion portion 141.

[0056] In some embodiments, the first protrusion 141 is provided with a second guide surface 1411, and the inclination direction of the second guide surface 1411 is the same as the inclination direction of the first slot 131, such as... Figure 8 As shown. For example, the second guide surface 1411 is the upper surface or side surface of the first protrusion portion 141. In the handle housing of this embodiment, the second guide surface 1411 is provided on the first protrusion portion 141. When the first slot portion 131 abuts against the first protrusion portion 141, the second guide surface 1411 can guide the first slot portion 131 to facilitate the engagement of the first slot portion 131 and the first protrusion portion 141.

[0057] In this embodiment, the handle housing may have a first guide surface 1311 provided only at the end of the first slot portion 131; or a second guide surface 1411 provided only on the first protrusion portion 141; or a first guide surface 1311 may be provided at the end of the first slot portion 131, while a second guide surface 1411 is provided on the first protrusion portion 141. The cooperation of the first guide surface 1311 and the second guide surface 1411 makes it easier for the first slot portion 131 and the first protrusion portion 141 to snap together.

[0058] In some embodiments, the handle housing also includes an end cap 160, such as Figure 1 As shown. The end cap 160 has a receiving portion 161. When the end cap 160 is connected to the first housing 110 and / or the second housing 120, the receiving portion 161 is used to receive the first slot portion 131 and the first protrusion portion 141, as shown. Figure 1 and Figure 9 As shown. In this embodiment, the handle housing, through the provision of the end cap 160, not only enhances the aesthetics of the handle housing, but also prevents the first slot portion 131 and the first protrusion portion 141 from being exposed and damaged, and also enhances the sealing performance of the handle housing.

[0059] For example, the end cap 160 is provided with a pin 162, and the second housing 120 is provided with a socket 121. By inserting the pin 162 into the socket 121, the end cap 160 and the second housing 120 can be connected. Figure 7 and Figure 9 As shown. However, it is not limited to this; the insertion hole 121 may also be provided on the first housing 110.

[0060] It is known that a socket 121 may also be provided on the end cap 160, and correspondingly, a pin may be provided on the first housing 110 and / or the second housing 120.

[0061] Furthermore, sealant can be applied to the joints between the pin 162 and the socket 121, and between the end cap 160 and the first housing 110 and the second housing 120, to further enhance the sealing performance of the handle housing.

[0062] In some embodiments, the slot portion 130 further includes a second slot portion 132, which is located on the first housing 110 and / or the second housing 120. The protrusion portion 140 further includes a second protrusion portion 142, which is located on the first housing 110 and / or the second housing 120, and the second slot portion 132 engages with the second protrusion portion 142.

[0063] For example, a plurality of second slot portions 132 are spaced apart along the axial direction of the first housing 110, such as... Figure 4 and Figure 5 As shown. Correspondingly, at corresponding positions on the second housing 120, a plurality of second protrusions 142 are spaced apart, as shown. Figure 7 As shown. The reliable connection between the first housing 110 and the second housing 120 can be ensured by the cooperation of the multiple second slot portions 132 and the multiple second protrusion portions 142.

[0064] For example, the second slot portion 132 can be arranged vertically or at an angle.

[0065] The second aspect of this embodiment describes the handle in detail.

[0066] The handle in this embodiment includes the handle housing of any of the technical solutions in this embodiment. The remaining structure of the handle can be the same as the prior art, and will not be described again here. For example, the handle may also include a rotating wheel, circuit board and other structures located inside the handle housing, and the handle may also include operating components such as a photo button, suction valve 170, and lever 180 located on the handle housing.

[0067] The handle of this embodiment includes the handle housing of any of the technical solutions in this embodiment. When assembling the handle housing, the risk of the first slot portion 131 being broken or damaged can be reduced, so that the handle of this embodiment can improve the assembly efficiency of the handle housing and the product qualification rate.

[0068] The third aspect of this embodiment provides a detailed description of the endoscope.

[0069] The endoscope of this embodiment includes a handle according to any of the technical solutions in this embodiment. The remaining structure of the endoscope is the same as that of the prior art, and will not be described in detail here. Exemplarily, the endoscope may also include an insertion portion disposed at the distal end of the handle, and the endoscope may also include a cable connected to a circuit board.

[0070] The endoscope in this embodiment may be a digestive endoscope, bronchoscope, nephroscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This embodiment does not impose specific restrictions on the type of endoscope.

[0071] The endoscope of this embodiment, including the handle of any of the technical solutions in this embodiment, has the advantages of high assembly efficiency of the handle housing and high product qualification rate.

[0072] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
