[0031] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of the present utility model.

[0032] It should be noted that in each embodiment of the present utility model, "proximal end" and "distal end" refer to the relative distances from the user in the usage environment of the endoscope and its accessories. Among them, 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 the understanding of a handle housing, an endoscope handle and an endoscope of the present utility model provided by the embodiments of the present utility model, the related technologies thereof will be introduced below in conjunction with the application scenarios.

[0034] In the related technologies, an insertion part sheath is provided between the endoscope handle housing and the endoscope insertion part for clamping the sheath tube 300. However, problems such as the sheath tube 300 slipping off from the insertion part sheath often occur. After research, the inventor found that the main reason for the slipping of the sheath tube 300 is that the connection between the insertion part sheath and the sheath tube 300 is unstable, and the strength of the insertion part sheath itself is insufficient, resulting in its inability to form sufficient support for the sheath tube 300.

[0035] In view of this, the embodiments of the present utility model provide a handle housing, an endoscope handle and an endoscope of the endoscope. The following combines Figures 1-7 , and details the technical solutions disclosed in each embodiment of the present utility model.

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

[0037] In some embodiments, the handle housing 100 of the endoscope is for the user to hold. In the medical field, doctors will perform a series of operations on the endoscope by holding the handle housing 100, and the outer surface of the handle housing 100 is usually configured to conform to the shape of the human hand. The handle housing 100 includes: a housing main body 110 and an attachment portion 120. The attachment portion 120 is located at the distal end of the housing main body 110, and the housing main body 110 and the attachment portion 120 are integrally formed. The handle housing 100 installs a sheath 300 through the attachment portion 120. The attachment portion 120 is used to clamp the sheath 300 to fix the sheath 300 outside the insertion portion 400 of the endoscope.

[0038] Among them, the interior of the housing main body 110 contains relevant accessories for endoscope operation. Since it needs to be held, it is made of a relatively hard material. In the prior art, the insertion portion sheath is often made of soft rubber, with poor hardness, and may be bent and deformed, and the support for the sheath 300 is insufficient, resulting in the sheath 300 being more likely to slip off the insertion portion sheath. In this embodiment, the attachment portion 120 and the housing main body 110 are integrally formed, so that the material for manufacturing the attachment portion 120 is the same as that of the housing main body 110, improving the structural strength and stiffness of the attachment portion 120. Specifically, the opening of the sheath 300 can be in interference fit with the attachment portion 120. Since the strength and stiffness of the attachment portion 120 itself are increased, the support effect on the sheath 300 is better, and the hard material will not have the above-mentioned bending and other situations, which is convenient for clamping and improves the connection stability between the sheath 300 and the attachment portion 120.

[0039] At the same time, the integral formation of the housing main body 110 and the attachment portion 120 also simplifies the connection structure between the insertion portion protective sleeve and the handle housing 100, reduces the use of relevant connection components, and omits the process of splicing two components during the production process, reducing the time cost and economic cost of manufacturing the handle housing 100.

[0040] Among them, the type of the sheath 300 clamped by the attachment portion 120 in the embodiments of the present invention is not limited. Exemplarily, the sheath 300 can be a protective sleeve for protecting the insertion portion 400 of the endoscope, or an immersion sheath for disinfecting the insertion portion 400, etc.

[0041] In the scenario of using an immersion sheath, since the attachment portion 120 and the housing main body 110 are integrally formed, its stiffness is increased. Even if there is a swing between the immersion sheath and the insertion portion 400 due to the actions or gravity of the operator during use, the attachment portion 120 will not deform, ensuring the connection reliability with the proximal end of the sheath 300, thus achieving the technical implementation of preventing the immersion sheath from detaching.

[0042] In addition, due to the increased stiffness of the attachment portion 120, it will not deform when abutting against the inner wall of the immersion sheath, and can always maintain the pressing effect on the inner wall of the immersion sheath, thereby ensuring effective sealing performance to prevent the disinfection solution from overflowing and avoiding contamination and waste.

[0043] Furthermore, since the attachment portion 120 and the housing main body 110 are integrally formed, the strength of the attachment portion 120 is also improved. That is to say, its anti-damage performance is improved. In this way, during the process of connecting and pressing against each other between the attachment portion 120 and the sheath tube 300 such as the immersion sheath, the attachment portion 120 can be effectively prevented from being damaged, and the service life of the handle is extended.

[0044] It is worth mentioning that the handle housing 100 of the embodiment of the present utility model is not limited to the application scenario of the endoscope, especially it can be used in the scenario of a sputum aspirator mirror. Based on the structural feature that the attachment portion 120 and the housing main body 110 are integrally formed, its cost is greatly reduced, which is extremely matched with the consumption and large demand of the sputum aspirator mirror, and can reduce the burden on patients. In the scenario of multiple reuses of the same sputum aspirator mirror for the same patient, it is necessary to disinfect the insertion portion 400 of the sputum aspirator mirror. By preventing the immersion sheath from detaching and providing better sealing performance for the disinfection solution as described above, a better experience can be brought to the patient.

[0045] In order to facilitate the assembly of the endoscope handle, the handle housing 100 can adopt a structural form of at least two sub-housings. An installation space for accommodating internal components can be formed between the sub-housings, and through the mutual docking and assembly between the sub-housings, the assembly of the endoscope handle can be quickly completed. Of course, the embodiment of the present utility model does not limit the specific structural form of the handle housing 100.

[0046] In some embodiments, as Figure 2 shown, the housing main body 110 may include a first sub-housing 111 and a second sub-housing 112, and the first sub-housing 111 and the second sub-housing 112 can be docked and assembled.

[0047] Furthermore, a first attachment sub-portion 121 is provided at the distal end of the first sub-housing 111, and the two are integrally formed. A second attachment sub-portion 122 is provided at the distal end of the second sub-housing 112, and the two are integrally formed. By means of docking and assembly, it is convenient to install the internal components of the housing main body 110, simplifies the assembly work of the handle housing 100, and at the same time, the process of separately installing the attachment portion 120 and the housing main body 110 is also omitted, saving the production time cost.

[0048] In some embodiments, the housing main body 110 may further include a third sub-housing and a fourth sub-housing. An attachment portion 120 is provided at the distal end of the third sub-housing, and the two are integrally formed. The third sub-housing and the fourth sub-housing may also be docked and assembled together to jointly form the housing main body 110 and the attachment portion 120. In this embodiment, the attachment portion 120 is an integral body without seams, making the strength and stiffness of the attachment portion 120 greater, and further improving the connection stability between the attachment portion 120 and the sheath 300.

[0049] In some embodiments, there is at least one protrusion 200 on the outer side of the attachment portion 120. The protrusion 200 is used to support the sheath wall to clamp the attachment portion 120 and the sheath 300.

[0050] In some embodiments, the protrusion 200 may be at any position on the outer side of the attachment portion 120. In a specific implementation, the protrusions 200 may be distributed on each side along the circumferential direction of the attachment portion 120 to ensure that the protrusions 200 can be firmly clamped with the sheath 300 at each position in the circumferential direction. In some embodiments, the protrusions 200 may also be arranged in various distribution manners such as continuous distribution, spaced distribution or dot distribution, which are not limited herein.

[0051] In some embodiments, the protrusion 200 may be of various shapes. For example, it may be a trapezoidal protrusion, a conical protrusion, etc.

[0052] In some embodiments, the protrusion 200 may be annular. As Figure 3 shown, the annular protrusion 200 is arranged to surround the attachment portion 120 along the circumferential direction. The annular structure can form a stable support for the sheath 300 in the circumferential direction of the attachment portion 120 and can maintain the same force in all directions, making the sheath 300 receive uniform force in all directions in the circumferential direction. 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 fixedly connected together by means of bonding or the like.

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

[0055] In some embodiments, the radial dimension D of the plurality of annular protrusions 200 may gradually increase in the direction 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 under sufficient deformation space, facilitating the insertion of the sheath 300 and improving the convenience of installing the sheath 300. The protrusions 200 located at the proximal end are less likely to deform under limited deformation space, and the connection between the sheath 300 and the protrusions 200 is tighter, improving the connection stability between the sheath 300 and the attachment portion 120.

[0056] Exemplarily, the radial dimension D of each annular protrusion 200 may change one by one, 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 may change at intervals, that is, taking a plurality of (greater than or equal to two) annular protrusions 200 as a group, 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 change manner of the radial dimension D of each annular protrusion 200 is not limited herein.

[0057] In some embodiments, as Figure 3 shown, the plurality of annular protrusions 200 are arranged at intervals along the axial direction of the attachment portion 120. Along the direction from the distal end to the proximal end of the handle housing, the change trend of the interval distance between different annular protrusions 200 may be gradually increasing. Similarly, the interval distance between different annular protrusions 200 may change one by one or at intervals.

[0058] In some embodiments, the mutual relationship of the interval distances of the plurality of annular protrusions 200 satisfies 0.9 ≤ L1:L2 < 1, where, among the interval distances between adjacent two protrusions 200, L1 is the interval distance between the protrusions 200 closer to the distal end of the attachment portion 120, and L2 is the interval distance between the protrusions 200 closer to the proximal end of the attachment portion 120. Specifically, since the radial dimension D of the aforementioned annular protrusions 200 may vary, when the annular protrusions 200 with different radial dimensions D are snap-fitted with the sheath 300, the sheath 300 is subjected to different forces at different contact parts. Therefore, adjusting the interval distance between the annular protrusions 200 can effectively make the force on the snap-fitting part between the attachment portion 120 and the sheath 300 more uniform, avoiding cracking of the sheath 300 due to uneven force and affecting the use.

[0059] In some embodiments, as Figure 4 shown, a reinforcing rib 130 is provided inside the attachment portion 120. The reinforcing rib 130 may be integrally formed with the attachment portion 120 and is used to enhance the strength and stiffness of the attachment portion 120, avoiding cracking or breaking of the attachment portion 120 during interference snap-fitting with the sheath 300.

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

[0061] In some embodiments, an installation groove 131 is provided on the reinforcing rib 130. The installation groove 131 is used to fix the position of the insertion portion 400 of the endoscope installed in the handle housing 100, so as to prevent the insertion portion 400 from shaking or shifting in position during use, which may affect the use function of the endoscope.

[0062] In some embodiments, the contour shape of the installation groove 131 can be various. For example, the contour shape of the surface of the installation groove 131 in contact with the insertion portion 400 can be a curved surface type, a square type, etc.

[0063] In some embodiments, the handle housing 100 further includes a clamping post 140, as Figure 6 shown, the clamping post 140 can be arranged at the junction of two adjacent side walls of the handle housing 100.

[0064] In some embodiments, the clamping post 140 can also be correspondingly arranged at any position of the handle housing 100. For example, on the side wall of the handle housing 100.

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

[0066] Specifically, the clamping post located on the side wall of the handle housing 100 can effectively improve the strength of the side wall of the handle housing 100, further help the connection between different sub - housings in the housing body 110, and ensure the stability of the connection of the handle housing 100. At the same time, the clamping post 140 located at the junction of two adjacent side walls of the handle housing 100 can stabilize the structure stability of stress - weak parts 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 the present utility model further provides an endoscope handle, which includes the handle housing 100 of the endoscope mentioned in any of the foregoing solutions. Thus, this handle has the beneficial effects of the foregoing handle housing 100, which will not be elaborated herein.

[0068] An embodiment of the present utility model further provides an endoscope, which includes the aforementioned endoscope handle; the endoscope of the embodiment of the present utility model can be a bronchoscope, a sputum aspirator, a pyeloscope, an esophagoscope, a gastroscope, a colonoscope, an otoscope, a nasal speculum, an oral mirror, a laryngoscope, a vaginoscope, a laparoscope, an arthroscope, etc. The embodiment of the present utility model does not specifically limit the types of endoscopes.

[0069] The above are only the embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the scope of the claims of the present utility model.
