An endoscope handle housing, an endoscope handle, and an endoscope. Technical Field

[0001] This application relates to the field of medical device technology, and in particular to an endoscope handle housing, an endoscope handle, and an endoscope. Background Technology

[0002] With the continuous development of medical technology, endoscopes have been widely used in the diagnosis and treatment of diseases. Endoscopes can be inserted into the human body through the insertion part via natural passages (such as the mouth) to assist doctors in observing the lesions of patients. The insertion part of the endoscope can be controlled by the endoscope handle, and it is usually for single use.

[0003] In related technologies, the distal end of the endoscope handle is usually equipped with an insertion sleeve. This sleeve is used to engage and assemble protective sheaths, soaking sheaths, and other tubing to protect or disinfect the insertion area. However, in practice, protective sheaths and other tubing often slip off the insertion sleeve. Utility Model Content

[0004] This application provides an endoscope handle housing, an endoscope handle, and an endoscope, which can at least solve the problem of the sheath slipping off the insertion portion of the endoscope in related technologies.

[0005] In a first aspect, embodiments of this application provide a handle housing for an endoscope, for a user to hold.

[0006] The handle housing includes: a housing body and an attachment portion, the attachment portion being located at the distal end of the housing body, and the housing body and the attachment portion being integrally formed; the handle housing is fitted with a sheath via the attachment portion, the attachment portion being used to engage the sheath to fix the sheath to the outside of the insertion portion of the endoscope.

[0007] In some embodiments of this application, the handle housing further includes a reinforcing rib disposed on its inner wall, the reinforcing rib being disposed corresponding to the attachment portion; and / or, the outer peripheral surface of the attachment portion is provided with a protrusion, the attachment portion being secured to the sheath tube through the protrusion; and / or, the handle housing 100 further includes a snap-fit ​​post 140 for realizing the docking assembly between its sub-shells, the snap-fit ​​post 140 being disposed at the junction of two adjacent side walls on the corresponding sub-shell.

[0008] In some embodiments of this application, at least some of the reinforcing ribs are provided with mounting grooves, which can be used to position and place the insertion part.

[0009] In some embodiments of this application, the shell body includes a first sub-shell and a second sub-shell, the first sub-shell and the second sub-shell being dockable and assembleable. The handle shell includes a first attachment portion and a second attachment portion, the first attachment portion being disposed at the distal end of the first sub-shell and the two being integrally formed, the second attachment portion being disposed at the distal end of the second sub-shell and the two being integrally formed, the first attachment portion and the second attachment portion being mated to form the attachment portion; or, the shell body includes a third sub-shell and a fourth sub-shell that are dockable and assembleable, the attachment portion being disposed at the distal end of the third sub-shell and the two being integrally formed.

[0010] In some embodiments of this application, there are multiple protrusions, which are annular and arranged around the circumference of the attachment portion, wherein: the radial dimension D of each protrusion is the same; or, the radial dimension D of each protrusion gradually increases along the direction from the distal end to the proximal end of the handle housing.

[0011] In some embodiments of this application, the protrusions are spaced apart along the axial direction of the attachment, and the spacing between two adjacent protrusions gradually increases along the direction from the distal end to the proximal end of the handle housing.

[0012] In some embodiments of this application, the spacing between two adjacent protrusions satisfies the following relationship: 0.9≤L1:L2<1, where L1 is the spacing between the protrusions closer to the distal end of the attachment portion, and L2 is the spacing between the protrusions closer to the proximal end of the attachment portion.

[0013] In some embodiments of this application, the handle housing is used for a suction endoscope.

[0014] Secondly, embodiments of this application provide an endoscope handle, including the handle housing described in the first aspect of this application.

[0016] The technical solution disclosed in this application has the following beneficial effects:

[0017] In the endoscope handle housing disclosed in this application, the main body and the attachment portion are integrally formed. Using a material with high hardness to make the attachment portion enhances its strength and rigidity, allowing it to provide sufficient support for the mating sheath. This improves the stability of the connection between the sheath and the attachment portion, preventing the sheath from easily slipping off.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] It should be noted that in the various embodiments of this application, "proximal end" and "distal end" refer to the position of the endoscope and its accessories relative to the user in the usage environment. The end closer to the user is designated as the "proximal end", and the end farther from the user is designated as the "distal end".

[0033] To facilitate understanding of the endoscope handle housing, endoscope handle, and endoscope provided in the embodiments of this application, the relevant technologies will first be introduced in conjunction with the application scenario.

[0034] In related technologies, an insertion sleeve is provided between the endoscope handle housing and the endoscope insertion part to secure the sheath 300. However, problems such as the sheath 300 slipping off the insertion sleeve often occur. Through research, the inventors discovered that the slippage of the sheath 300 is mainly due to the unstable connection between the insertion sleeve and the sheath 300, and the insufficient strength of the insertion sleeve itself, which prevents it from providing sufficient support for the sheath 300.

[0035] In view of this, embodiments of this application provide an endoscope handle housing, an endoscope handle, and an endoscope. The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to Figures 1-7.

[0036] As shown in Figures 1-7, the endoscope handle housing 100 disclosed in this specification includes a housing body 110 and an attachment portion 120.

[0037] In some embodiments, the endoscope's handle housing 100 is designed for a user to hold. In the medical field, doctors perform a series of operations on the endoscope by holding the handle housing 100, and the outer surface of the handle housing 100 is typically shaped to conform to the human hand. The handle housing 100 includes a housing body 110 and an attachment portion 120, the attachment portion 120 being located at the distal end of the housing body 110, and the housing body 110 and the attachment portion 120 being integrally formed; the handle housing 100 is fitted with a sheath 300 via the attachment portion 120, the attachment portion 120 being used to hold the sheath 300 in place, thereby securing the sheath 300 to the outside of the endoscope's insertion portion 400.

[0038] The shell body 110 contains accessories for endoscope operation. Because it needs to be held, it is made of a relatively rigid material. In existing technology, the insertion sleeve is often made of soft rubber, which has poor rigidity and may be prone to bending and deformation, and provides insufficient support for the sheath 300, making it easier for the sheath 300 to slip off the insertion sleeve. In this embodiment, the attachment part 120 is integrally formed with the shell body 110, making the material of the attachment part 120 the same as that of the shell body 110, thus improving the structural strength and rigidity of the attachment part 120. Specifically, the opening of the sheath 300 can be press-fitted with the attachment part 120. Due to the increased strength and rigidity of the attachment part 120, it provides better support for the sheath 300, and the rigid material does not cause the aforementioned bending, facilitating a secure connection and improving the stability of the connection between the sheath 300 and the attachment part 120.

[0039] Meanwhile, the integral molding of the shell body 110 and the attachment part 120 simplifies the connection structure between the insertion part protective sleeve and the handle shell 100, reduces the use of related connecting components, and eliminates the process of splicing the two components during production, thereby reducing the time and economic costs of producing the handle shell 100.

[0040] In this application, the type of sheath 300 that is fastened by the attachment part 120 in the embodiments is not limited. For example, the sheath 300 can be a protective sleeve for the insertion part 400 of the endoscope, or a soaking sheath for disinfecting the insertion part 400.

[0041] In scenarios where an immersion sheath is used, since the attachment part 120 is integrally formed with the shell body 110, its rigidity is increased. Even if the immersion sheath and the insertion part 400 swing during use due to the operator's movements or gravity, the attachment part 120 will not deform, which can ensure the reliability of its connection with the proximal end of the sheath tube 300, thereby achieving the technical realization of preventing the immersion sheath from detaching.

[0042] In addition, due to the increased rigidity of the attachment part 120, it will not deform when it comes into contact with the inner wall of the soaking sheath, and can always maintain the pressure effect on the inner wall of the soaking sheath, thereby ensuring effective sealing performance to prevent the disinfectant from overflowing and avoid pollution and waste.

[0043] Furthermore, since the attachment part 120 is integrally formed with the shell body 110, the strength of the attachment part 120 is also improved, that is, its damage resistance is improved. In this way, during the process of the attachment part 120 being connected to the sheath tube 300 such as the soaking sheath and pressing against each other, the attachment part 120 can be effectively prevented from being damaged, thus extending the service life of the handle.

[0044] It is worth mentioning that the handle housing 100 of this embodiment is not limited to the application scenarios of the endoscope, especially for use with a suction endoscope. Based on the structural feature of the attachment portion 120 being integrally formed with the housing body 110, its cost is significantly reduced, which is highly compatible with the high consumption and demand of suction endoscopes, thus alleviating the burden on patients. In scenarios where the same suction endoscope is reused multiple times for the same patient, the insertion portion 400 of the suction endoscope needs to be disinfected. By preventing the soaking sheath from detaching and providing better sealing performance against disinfectant, a better experience can be provided to the patient.

[0045] To facilitate the assembly of the endoscope handle, the handle housing 100 can adopt a structure with at least two sub-housings. These sub-housings can form an installation space to accommodate internal components, and the endoscope handle can be quickly assembled by interlocking the sub-housings. Of course, the embodiments of this application do not limit the specific structural form of the handle housing 100.

[0046] In some embodiments, as shown in FIG2, the shell body 110 may include a first sub-shell 111 and a second sub-shell 112, which can be docked and assembled.

[0047] Furthermore, the first sub-shell 111 has a first attachment part 121 at its distal end, and the two are integrally formed; the second sub-shell 112 has a second attachment part 122 at its distal end, and the two are integrally formed. This docking assembly method facilitates the installation of internal components of the shell body 110, simplifies the assembly of the handle shell 100, and also eliminates the need for additional steps in installing the attachment part 120 to the shell body 110, saving production time and costs.

[0048] In some embodiments, the shell body 110 may further include a third sub-shell and a fourth sub-shell, with an attachment portion 120 provided at the distal end of the third sub-shell, and the two are integrally formed. The third sub-shell and the fourth sub-shell may also be joined together to form the shell body 110 and the attachment portion 120. In this embodiment, the attachment portion 120 is a single piece without seams, which increases the strength and rigidity of the attachment portion 120 and further improves the connection stability between the attachment portion 120 and the sheath 300.

[0049] In some embodiments, the attachment portion 120 has at least one protrusion 200 on its outer side, the protrusion 200 being used to support the sheath wall to engage the attachment portion 120 with the sheath 300.

[0050] In some embodiments, the protrusion 200 can be located at any position outside the attachment portion 120. In specific implementations, the protrusion 200 can be distributed along various circumferential sides of the attachment portion 120 to ensure that the protrusion 200 can be securely engaged with the sheath 300 at various circumferential positions. In some embodiments, the protrusion 200 can also be provided in various distribution methods such as continuous distribution, intermittent distribution, or dotted distribution, and there is no limitation herein.

[0051] In some embodiments, the protrusion 200 can be of various shapes, such as a trapezoidal protrusion, a conical protrusion, etc.

[0052] In some embodiments, the protrusion 200 can be annular. As shown in FIG3, the annular protrusion 200 is arranged around the attachment portion 120 in the circumferential direction. The annular structure can provide stable support for the sheath 300 in the circumferential direction of the attachment portion 120 and can maintain the same force in all directions, so that the sheath 300 is subjected to uniform force in all circumferential directions. While stabilizing the connection position of the sheath 300, it can also ensure that the sheath 300 and the attachment portion 120 will not crack or break due to uneven force.

[0053] In some embodiments, the annular protrusion 200 may be integrally formed with the attachment portion 120, or may be fixed together by means of adhesive bonding or other methods.

[0054] In some embodiments, since the connection between the sheath 300 and the attachment 120 is generally an interference fit, in order to further increase the convenience and stability of the connection between the sheath 300 and the sheath, the radial dimension D of the plurality of annular protrusions 200 may be the same.

[0055] In some embodiments, the radial dimension D of the plurality of annular protrusions 200 can gradually increase from the distal end to the proximal end of the handle housing. Therefore, when installing the sheath 300, the protrusions 200 located at the distal end are more likely to deform with sufficient deformation space, facilitating the insertion of the sheath 300 and improving the ease of installation. The protrusions 200 located at the proximal end are less likely to deform with limited deformation space, resulting in a tighter connection between the sheath 300 and the protrusions 200 and improving the connection stability between the sheath 300 and the attachment 120.

[0056] For example, the radial dimension D of each annular protrusion 200 can vary sequentially, that is, the radial dimension D of each annular protrusion 200 is greater than the radial dimension D of the previous annular protrusion 200; or it can vary at intervals, that is, multiple (two or more) annular protrusions 200 are grouped together, and the radial dimension D of each group of annular protrusions 200 is greater than the radial dimension D of the previous group of annular protrusions 200. The way in which the radial dimension D of each annular protrusion 200 varies is not limited here.

[0057] In some embodiments, as shown in FIG3, a plurality of annular protrusions 200 are spaced apart along the axial direction of the attachment portion 120. The spacing between the different annular protrusions 200 may gradually increase along the direction from the distal end to the proximal end of the handle housing. Similarly, the spacing between the different annular protrusions 200 may vary individually or at intervals.

[0058] In some embodiments, the spacing between the plurality of annular protrusions 200 satisfies 0.9 ≤ L1 : L2 < 1, wherein, in the spacing between two adjacent protrusions 200, L1 is the spacing between protrusions 200 closer to the distal end of the attachment portion 120, and L2 is the spacing between protrusions 200 closer to the proximal end of the attachment portion 120. Specifically, since the radial dimension D of the aforementioned annular protrusions 200 can vary, when annular protrusions 200 with different radial dimensions D engage with the sheath 300, the sheath 300 experiences different forces at different contact points. Therefore, adjusting the spacing between the annular protrusions 200 can effectively make the engagement points of the attachment portion 120 and the sheath 300 more uniformly stressed, preventing the sheath 300 from cracking due to uneven stress and affecting its use.

[0059] In some embodiments, as shown in FIG4, the attachment portion 120 is provided with a reinforcing rib 130. The reinforcing rib 130 can be integrally formed with the attachment portion 120 to improve the strength and rigidity of the attachment portion 120 and prevent the attachment portion 120 from cracking or breaking when it is interference-fitted with the sheath tube 300.

[0060] In some embodiments, the reinforcing rib 130 may be located on the first attachment portion 121 and / or the second attachment portion 122.

[0061] In some embodiments, the reinforcing rib 130 is provided with a mounting groove 131, which is used to fix the position of the insertion part 400 of the endoscope installed in the handle housing 100, so as to prevent the insertion part 400 from shaking or shifting during use, which would affect the endoscope's function.

[0062] In some embodiments, the outline shape of the mounting groove 131 can be various. For example, the outline shape of the side of the mounting groove 131 that contacts the insertion part 400 can be curved, square, etc.

[0063] In some embodiments, the handle housing 100 further includes a snap-fit ​​post 140, as shown in FIG6. The snap-fit ​​post 140 may be disposed at the junction of two adjacent side walls of the handle housing 100.

[0064] In some embodiments, the snap-fit ​​post 140 may also be disposed at any position on the handle housing 100, for example, on the side wall of the handle housing 100.

[0065] In some embodiments, the snap-fit ​​post 140 is correspondingly disposed in the first sub-shell 111 and / or the second sub-shell 112 of the handle housing 100. Correspondingly, when the first sub-shell 111 and the second sub-shell 112 are engaged, if the first sub-shell 111 includes the snap-fit ​​post 140, a receiving cavity 141 is provided at a corresponding position in the second sub-shell 112 for interference engagement with the snap-fit ​​post 140. Similarly, when the third sub-shell and the fourth sub-shell are engaged, the corresponding snap-fit ​​post 140 is interference engaged with the receiving cavity 141.

[0066] Specifically, the snap-fit ​​pins are located on the side walls of the handle housing 100, which can effectively improve the strength of the side walls of the handle housing 100, further facilitating the connection between different sub-shells in the main body 110 and ensuring the stability of the handle housing 100 connection. At the same time, the snap-fit ​​pins 140 located at the junction of two adjacent side walls of the handle housing 100 can stabilize the structural stability of weak points such as corners and bends, and further improve the overall strength of the handle housing 100, ensuring the safe use of the handle housing 100.

[0067] An embodiment of this application also provides an endoscope handle, which includes the endoscope handle housing 100 mentioned in any of the foregoing solutions. Thus, the handle has the beneficial effects of the aforementioned handle housing 100, which will not be described in detail here.

[0068] The embodiments of this application also provide an endoscope, including the aforementioned endoscope handle; the endoscope in the embodiments of this application can be a bronchoscope, suction endoscope, nephroscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc., and the embodiments of this application do not specifically limit the type of endoscope.

[0069] The above description is merely an embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this application should be included within the scope of the claims of this application.
