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 internal components such as a rotating wheel, steel cable, and circuit board. The housing also houses operating parts such as a camera button, suction valve, and lever. When using the endoscope, the operator holds the handle with their left hand and controls the lever with their thumb. Handle designs in related technologies often only consider the installation layout of the internal components, neglecting the compatibility between the handle and the operator. This leads to strain on the operator during prolonged use and can even affect operational accuracy.

[0004] Therefore, improving the endoscope handle housing to provide a labor-saving and comfortable handle housing 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 problem in related technologies where holding the handle for a long time is laborious and may even affect the accuracy of operation.

[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 housing body. Along the axial direction of the housing body, the housing body includes a first housing portion and a second housing portion. The first housing portion is used to mount a rotating wheel. The second housing portion is located at the distal end of the first housing portion. The height of the first housing portion is greater than the height of the second housing portion, and the first housing portion is able to support at least the base of the index finger and the palm near the base of the index finger.

[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] The handle housing of this utility model includes a housing body. Along the axial direction of the housing body, the housing body includes a first housing portion and a second housing portion, and the height of the first housing portion is greater than the height of the second housing portion. When the operator grips the handle, because the height of the first housing portion is greater than the height of the second housing portion, the base of the index finger and the area of ​​the palm near the base of the index finger can fit against the first housing portion, or the bases of the index and middle fingers and the area of ​​the palm near the base of the index and middle fingers can fit against the first housing portion. Thus, the first housing portion can provide support for at least the base of the index finger and the area of ​​the palm near the base of the index finger.

[0015] As can be seen, the handle housing of this utility model, through the supporting function of the first housing part, can improve the comfort of the operator holding the handle for a long time and reduce the operator's fatigue. That is, the handle housing of this utility model solves the technical problem in the related art that the handle is difficult to hold for a long time, and may even affect the accuracy of operation.

Detailed Implementation

[0026] 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.

[0027] 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.

[0028] 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".

[0029] In related technologies, handles typically have a wider proximal end than distal end due to the presence of structures such as a rotary wheel and suction valve. When the operator holds the handle, the index finger rests on the wider part of the handle (or on the suction valve or the shutter button), the middle, ring, and little fingers rest on the narrower part, and the thumb rests on the wider part (or on the toggle switch). The inventors discovered that when the operator holds the handle, the base of the fingers and the area of ​​the palm near the base of the fingers cannot fit snugly against the outer surface of the handle, especially the index and middle fingers. Because the hand cannot receive effective support, prolonged use of the handle becomes strenuous and can even affect operational accuracy.

[0030] Therefore, the handle housing of this application increases the height of the first housing portion so that the base of the index finger and the palm near the base of the index finger can fit into the first housing portion, or the base of the index and middle fingers and the palm near the base of the index and middle fingers can fit into the first housing portion. Thus, the first housing portion can provide support for at least the base of the index finger and the palm near the base of the index finger, thereby reducing the fatigue of the operator when holding the handle for a long time.

[0031] The following is in conjunction with the appendix Figures 1 to 8 The present application provides a detailed description of the handle housing, handle, and endoscope through specific embodiments and application scenarios.

[0032] The first aspect of this embodiment describes the handle housing in detail.

[0033] The handle housing of this embodiment is used in an endoscope, particularly for the handle portion of an endoscope. The handle housing of this embodiment includes a housing body 100, such as... Figure 1 As shown. The housing body 100 has an internal cavity for mounting the reel, wire rope, circuit board, etc. Figures 1-3 As shown, the housing body 100 also forms a mounting base for mounting operating components such as the photo button, suction valve, and toggle 130. The operator holds the handle and can perform corresponding operations by controlling the operation components.

[0034] In some embodiments, along the axial direction of the housing body 100, the housing body 100 includes a first housing portion 110 and a second housing portion 120, such as... Figure 2 As shown. Figure 2 As shown, the axial direction of the housing body 100 is the x-direction. The first housing portion 110 is used to mount the wheel. Specifically, the first housing portion 110 is located at the proximal end, and the second housing portion 120 is located at the distal end of the first housing portion 110. The second housing portion 120 can be used to mount circuit boards, cables, traction ropes, etc.

[0035] In some embodiments, the height of the first housing portion 110 is greater than the height of the second housing portion 120, and the first housing portion 110 is designed to support at least the base of the index finger and the area of ​​the palm near the base of the index finger. For example... Figure 2 As shown, the height of the first housing portion 110 and the height of the second housing portion 120 refer to the dimensions along the y-direction. Figure 2 As shown, H1 is half the height of the first housing portion 110, and H2 is half the height of the second housing portion 120. The height of the first housing portion 110 is greater than the height of the second housing portion 120, which can also be described as the first housing portion 110 being higher than the second housing portion 120 along the y-direction; or in other words, the first housing portion 110 protrudes from the second housing portion 120 along the y-direction.

[0036] like Figure 2 As shown, the proximal end of the second housing portion 120 (that is, the junction between the second housing portion 120 and the first housing portion 110) is formed as a transition portion. The height of the transition portion gradually increases from the distal end to the proximal end, thereby allowing a smooth transition between the first housing portion 110 and the second housing portion 120. In this embodiment, the height of the first housing portion 110 is greater than the height of the second housing portion 120, specifically meaning that the height of the first housing portion 110 is greater than the height of the main body portion of the second housing portion 120. The main body portion of the second housing portion 120 refers to the portion of the second housing portion 120 excluding the transition portion.

[0037] It is understood that the transition portion can also be part of the first housing portion 110. Similarly, the height of the transition portion gradually decreases from the proximal end to the distal end, thereby allowing the first housing portion 110 and the second housing portion 120 to transition smoothly.

[0038] In this embodiment, the "base of the index finger" refers to the area corresponding to the proximal phalanx of the index finger, specifically the part of the proximal phalanx of the index finger near the metacarpal bone, or the junction of the proximal phalanx and metacarpal bone. The "base of the palm near the base of the index finger" refers to the section of the metacarpal bone of the index finger near the proximal phalanx, or the junction of the metacarpal bone and proximal phalanx. The base of the middle finger and the area of ​​the palm near the base of the middle finger are similar to those of the index finger and will not be described further.

[0039] In this embodiment, since the height of the first housing portion 110 is greater than the height of the second housing portion 120, when the operator holds the handle, the base of the index finger and the palm near the base of the index finger can fit against the first housing portion 110, or the base of the index and middle fingers and the palm near the base of the index and middle fingers can fit against the first housing portion 110. Thus, the first housing portion 110 can provide support for at least the base of the index finger and the palm near the base of the index finger.

[0040] As can be seen, the handle housing of this embodiment, through the supporting function of the first housing part 110, can improve the comfort of the operator holding the handle for a long time and reduce the operator's fatigue. That is, the handle housing of this embodiment solves the technical problem in the related art that the handle is difficult to hold for a long time and may even affect the accuracy of operation.

[0041] In some embodiments, the height of the first housing portion 110 is greater than the height of the second housing portion 120 near the palm side. Near the palm side, that is, as... Figure 2 The lower side is shown. In this embodiment, the handle housing has a height of the first housing portion 110 near the palm side that is greater than the height of the second housing portion 120. When the operator holds the handle, the first housing portion 110 near the palm side can provide support for at least the base of the index finger and the palm near the base of the index finger, thereby improving the operator's comfort when holding the handle for a long time and reducing the operator's fatigue when holding the handle for a long time.

[0042] In some embodiments, the height of the first housing portion 110 is greater than the height of the second housing portion 120 both near the palm and away from the palm. Figure 2 As shown. The side closer to the palm and the side further from the palm refer to, respectively, as... Figure 2 The lower and upper sides are shown. In this embodiment, the handle housing has a height greater than the height of the second housing portion 120 on both the side closer to the palm and the side farther from the palm. This not only provides support through the first housing portion 110 near the palm, but also allows the handle housing to form a symmetrical structure, which enhances the aesthetics of the handle housing.

[0043] In some embodiments, the height of the first housing portion 110 satisfies: H1 - H2 ≥ 0.3 mm. Wherein, H1 is half the height of the first housing portion 110, and H2 is half the height of the second housing portion 120, such as... Figure 2 As shown. Or, H1 is the height of the first housing portion 110 on the upper housing 100a and / or the lower housing 100b, and H2 is the height of the second housing portion 120 on the upper housing 100a and / or the lower housing 100b.

[0044] For example, the height of the first housing portion 110 satisfies: H1-H2=0.3mm, or H1-H2=0.4mm, or H1-H2=0.5mm, or H1-H2=0.6mm, or H1-H2=0.8mm, or H1-H2=0.8mm.

[0045] It is understood that the height difference between the first housing portion 110 and the second housing portion 120 can be made into various specifications based on different users. It is also understood that the height difference between the first housing portion 110 and the second housing portion 120 can be any other value, as long as it satisfies the requirement that when the operator holds the handle, the side of the first housing portion 110 near the palm can provide support for at least the base of the index finger and the part of the palm near the base of the index finger.

[0046] For example, when the height of the first housing portion 110 is greater than the height of the second housing portion 120 only on the side near the palm, the height difference between the first housing portion 110 and the second housing portion 120 is greater than or equal to 0.3mm, which means that the height difference between the two on the side near the palm is greater than or equal to 0.3mm.

[0047] For example, when the height of the first housing portion 110 is greater than the height of the second housing portion 120 on both the side near the palm and the side away from the palm, the height difference between the first housing portion 110 and the second housing portion 120 is greater than or equal to 0.3 mm, which means that the height difference between the side near the palm and the side away from the palm is greater than or equal to 0.3 mm.

[0048] In some embodiments, a first groove 111 is formed on the side surface of the first housing portion 110, such as... Figure 3 As shown. When the operator grips the handle housing, the first groove 111 forms a position for the index finger. The side of the first housing portion 110 refers to the side where the tip of the index finger rests. (As shown...) Figure 3 As shown, the first groove 111 is located near the end of the first housing portion 110. (As indicated...) Figure 3 and Figure 4 As shown, the first groove 111 is located on the inner side of the proximal end and tilts towards the distal end.

[0049] In this embodiment, the handle housing has a first groove 111 provided on the first housing part 110. When the operator holds the handle, the first groove 111 can be used to position the index finger, which can also improve the fit between the index finger and the first housing part 110, thereby further enhancing the comfort of use.

[0050] In some embodiments, a soft rubber layer 112 is provided on the first housing portion 110 near the palm. Alternatively, the first housing portion 110 may have soft rubber layers 112 on both the palm-side and palm-away sides, such as... Figure 3 and Figure 4 As shown. For example, the hardness of the soft rubber layer 112 is less than the hardness of the first housing portion 110. For example, the soft rubber layer 112 is formed of materials such as rubber or silicone. For example, the first housing portion 110 is provided with a mounting groove 113, and the soft rubber layer 112 is disposed within the mounting groove 113, such as... Figure 5 and Figure 6 As shown. The soft adhesive layer 112 can be installed in the mounting groove 113 by means of bonding, injection molding, etc.

[0051] In this embodiment, the handle housing has a soft rubber layer 112 on the side of the first housing 110 near the palm. When the base of the index finger and the palm near the base of the index finger are in contact with the first housing 110, or when the base of the index and middle fingers and the palm near the base of the index and middle fingers are in contact with the first housing 110, hand comfort can be improved.

[0052] In some embodiments, a second groove 121 is formed on the side surface of the second housing portion 120, such as... Figure 3 As shown. When the operator grips the handle housing, the second groove 121 forms a middle finger position. Alternatively, a second groove 121 is formed on the side of the second housing portion 120, and when the operator grips the handle housing, the second groove 121 forms a middle and ring finger position. Alternatively, a second groove 121 is formed on the side of the second housing portion 120, and when the operator grips the handle housing, the second groove 121 forms a middle, ring, and little finger position. That is, when the operator grips the handle, the second groove 121 can be used to place the middle finger; or the second groove 121 is used to place the middle and ring fingers; or the second groove 121 is used to place the middle, ring, and little fingers. Figure 3 and Figure 4 As shown, the second groove 121 is located near the end of the second housing portion 120.

[0053] In this embodiment, the handle housing has a second groove 121 provided on the second housing part 120. When the operator holds the handle, the second groove 121 can be used to center the finger, or to position the middle and ring fingers, or to position the middle, ring and little fingers, thereby improving the fit between the fingers and the second housing part 120 and further enhancing the comfort of use.

[0054] like Figure 3 As shown, the second groove 121 has a first housing portion 110 and a protrusion 122 on its two sides respectively. Taking the second groove 121 forming the middle finger position as an example, the two sides of the protrusion 122 can support the middle finger and the ring finger respectively, so as to further enhance the comfort of use.

[0055] In some embodiments, along the radial direction of the housing body 100, the housing body 100 includes an upper housing 100a and a lower housing 100b, which are connected to each other, such as... Figure 2 As shown. The radial direction of the housing body 100 refers to, as... Figure 2The y-direction is shown. For example, the upper housing 100a and the lower housing 100b are connected to each other via a snap-fit ​​structure and / or a screw structure. This type of fixed connection facilitates the installation and removal of the upper housing 100a and the lower housing 100b. Furthermore, the upper housing 100a and the lower housing 100b are also fixedly connected by adhesive bonding. Adhesive bonding at the joint between the upper housing 100a and the lower housing 100b enhances the reliability of the connection and also improves the sealing performance at the joint.

[0056] In some embodiments, both the upper housing 100a and the lower housing 100b have a first housing portion 110 and a second housing portion 120, such as Figure 2 As shown. The upper housing 100a has a first housing portion 110 and a second housing portion 120, and the first housing portion 110 and the second housing portion 120 on the upper housing 100a are an integral structure; meanwhile, the lower housing 100b has a first housing portion 110 and a second housing portion 120, and the first housing portion 110 and the second housing portion 120 on the lower housing 100b are an integral structure, as shown. Figure 7 and Figure 8 As shown.

[0057] like Figure 7 and Figure 8 As shown, both the upper housing 100a and the lower housing 100b have a portion of a first groove 111, a portion of a second groove 121, and a portion of a protrusion 122. When the upper housing 100a and the lower housing 100b are connected to each other, the first groove 111 on the upper housing 100a and the lower housing 100b together form a complete first groove 111; the second groove 121 on the upper housing 100a and the lower housing 100b together form a complete second groove 121; and the protrusion 122 on the upper housing 100a and the lower housing 100b together form a complete protrusion 122, as shown. Figure 2 As shown.

[0058] In this embodiment, the handle housing has a split structure in the radial direction of the housing body 100, with the upper housing 100a and the lower housing 100b connected to each other by a snap-fit ​​structure and / or a screw structure, which facilitates the installation of internal components of the handle housing. On the other hand, the first housing part 110 and the second housing part 120 are an integral structure, which ensures the smoothness of the connection between the first housing part 110 and the second housing part 120, which helps to enhance the comfort of holding the handle housing.

[0059] The second aspect of this embodiment describes the handle in detail.

[0060] The handle in this embodiment includes the handle housing of any of the technical solutions in this embodiment, such as... Figure 1As shown. The remaining structure of the handle can be the same as the prior art, and will not be described in detail 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 an operating component such as a photo button, a suction valve, and a toggle 130 located on the handle housing.

[0061] Compared to traditional handles, the handle in this embodiment can improve the comfort of the operator when holding the handle for a long time and reduce the operator's fatigue.

[0062] The third aspect of this embodiment provides a detailed description of the endoscope.

[0063] 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. For example, the endoscope may also include an insertion portion 200 disposed at the distal end of the handle, and the endoscope may also include a cable connected to a circuit board.

[0064] The endoscope in this embodiment may be a digestive endoscope, bronchoscope, nephroscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, ureteroscope, etc. This embodiment does not impose specific restrictions on the type of endoscope.

[0065] Compared to traditional endoscopes, the endoscope in this embodiment can improve the operator's comfort when holding the handle for a long time and reduce the operator's fatigue when holding the handle for a long time.

[0066] 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.
