Description

Technical Field

[0001] This application belongs to the field of medical device technology, specifically relating to an endoscope attachment device and an endoscope kit. Background Technology

[0002] An endoscope is a medical device that enters the body through natural cavities or minimally invasive incisions for visual examination and treatment. It is widely used in fields such as gastroenterology, respiratory medicine, and urology. Common types include gastroscopes, colonoscopes, and duodenoscopes.

[0003] In complex surgeries, multiple endoscopes are often used in combination to achieve coordinated operation. For example, a duodenoscope may be used in conjunction with an auxiliary endoscope to improve diagnostic and treatment accuracy. Currently, the devices available on the market for connecting two endoscopes are cumbersome and inconvenient to use. Utility Model Content

[0006] A base for attaching to the first endoscope;

[0007] A clamp is disposed on the base. The clamp includes a first clamping component and a second clamping component disposed opposite to each other. A clamping area for accommodating the second endoscope is formed between the first clamping component and the second clamping component.

[0011] In some embodiments, the first clamping arm has a first free end and a first fixed end disposed opposite to each other, the first free end being disposed on the side of the first fixed end away from the base, and the first guide portion being disposed on the first free end;

[0012] The second clamping arm has a second free end and a second fixed end disposed opposite to each other. The second free end is disposed on the side of the second fixed end away from the base, and the second guide portion is disposed on the second free end.

[0013] The distance between the first free end and the second free end is less than the distance between the first fixed end and the second fixed end.

[0014] In some embodiments, the first fixed end and the second fixed end are respectively connected to the base.

[0015] In some embodiments, the clamp further includes a connecting structure connected to the base and disposed between the first clamping arm and the second clamping arm;

[0016] The first fixed end and the second fixed end are respectively connected to the connecting structure.

[0017] In some embodiments, the clamp further includes a support pad detachably connected to the side of the connection structure facing the clamping area.

[0018] In some embodiments, the first guide portion is connected to the first free end of the first clamping arm and protrudes toward the second clamping arm;

[0019] The second guide portion is connected to the second free end of the second clamping arm and protrudes toward the first clamping arm.

[0020] In some embodiments, both the first guide portion and the second guide portion are roller structures;

[0021] The first free end is provided with a first mounting portion extending toward the second clamping arm, and the first guide portion is rotatably connected to the first mounting portion;

[0022] The second free end is provided with a second mounting portion extending toward the first clamping arm, and the second guide portion is rotatably connected to the second mounting portion.

[0023] In some embodiments, the first guide portion has a first mating surface opposite to the first arcuate surface, and the first mating surface covers the first free end;

[0024] The second guide portion faces away from the second mating surface of the second arc-shaped surface, and the second mating surface covers the second free end.

[0025] In some embodiments, the first guide portion extends from the first free end toward the clamping region in an arc-shaped bend;

[0026] The second guide portion extends from the second free end toward the clamping area in an arc-shaped bend.

[0027] In some embodiments, the first clamping arm and the first guide portion are configured as an integral structure, and the second clamping arm and the second guide portion are configured as an integral structure.

[0028] In some embodiments, the first clamping assembly further includes a first flexible portion, which is disposed on the side of the first guide portion facing the clamping area and connected to the first guide portion;

[0029] The second clamping assembly also includes a second flexible portion, which is disposed on the side of the second guide portion facing the clamping area and connected to the second guide portion.

[0030] In some embodiments, the first clamping assembly further includes a first protrusion connected to the first clamping arm, the first protrusion being disposed on the side of the first clamping arm facing the clamping area;

[0033] According to a second aspect of this application, an endoscope kit is provided, comprising:

[0034] The endoscope attachment device as described in any of the above embodiments, and,

[0036] In the endoscope attachment device provided in this application embodiment, a clamping area with an opening is formed by the relative arrangement of the first clamping component and the second clamping component of the clamp. The opening formed by the first and second arc-shaped surfaces guides the second endoscope to automatically slide along the arc-shaped contour to the center of the clamping area when it is inserted, achieving a quick "alignment and locking" connection, effectively alleviating the drawbacks of traditional devices that require repeated calibration and alignment. Furthermore, the curved surface design with opposing double arc-shaped surfaces forms at least three points of contact constraint with the outer wall of the second endoscope in the clamping state: while ensuring clamping stability, this contact mode allows the second endoscope to rotate circumferentially around its own axis through the extension characteristics of the arc-shaped surfaces, and to achieve fine-tuning of the pitch angle by utilizing the tilt angle tolerance between the curved surfaces. This dual adjustment mechanism enables the first and second endoscopes to coordinately adjust their relative posture in real time during surgery, meeting the dynamic needs of multi-scope collaborative operation in complex surgical procedures.

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 protection scope of this application.

[0051] In the description of this application, it should be understood that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

The terms "installed," "connected," and "linked" should be interpreted broadly, for example, they can be a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; they can be the internal communication of two devices or the interaction relationship between two devices, unless otherwise explicitly specified. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] Please see Figures 1 to 8 This application provides an endoscope attachment device 100 and an endoscope kit including the device. The endoscope attachment device 100 is used to connect a first endoscope 200 and a second endoscope 300, so that the operator (medical staff) can hold the two endoscopes with one hand and perform diagnostic and treatment operations together.

[0053] Please see Figure 1 and Figure 2 The endoscope attachment device 100 of Embodiment 1 of this application comprises a base 110 and a clamp 120 forming an integral structure, which are connected to each other. The base 110 is used to attach a first endoscope 200, and the clamp 120 is disposed on the side of the base 110 opposite to the first endoscope 200 and is used to attach a second endoscope 300. Optionally, the base 110 can be connected to the first endoscope 200 by means of bolts, adhesive, snap-fit, or plug-in.

[0054] The clamp 120 includes a first clamping component 130 and a second clamping component 140 disposed opposite to each other. A clamping region 160 for accommodating a second endoscope 300 is formed between the first clamping component 130 and the second clamping component 140. The second endoscope 300 can be placed into the clamping region 160 to be clamped and fixed by the first clamping component 130 and the second clamping component 140.

[0055] The first clamping assembly 130 has its free end at the end furthest from the base 110, and the second clamping assembly 140 has its free end at the end furthest from the base 110. An opening 161 of a clamping region 160 is formed between the free ends of the first clamping assembly 130 and the second clamping assembly 140. During the installation of the second endoscope 300, the free ends of the first clamping assembly 130 and the second clamping assembly 140 can move away from each other to receive the second endoscope 300. The first clamping assembly 130 has a first arcuate surface 133 at its free end, and the second clamping assembly 140 has a second arcuate surface 143 at its free end. The second arcuate surface 143 is disposed opposite to the first arcuate surface 133, and the opening 161 of the clamping region 160 is defined between them.

[0056] The "relative arrangement" of the first arc-shaped surface 133 and the second arc-shaped surface 143 means that they face each other in space. The first arc-shaped surface 133 and the second arc-shaped surface 143 together form a roughly trumpet-shaped guide structure at the opening 161, which can generate a funnel effect to a certain extent. When the second endoscope 300 is inserted, it is guided to automatically slide along the arc-shaped contour to the center of the clamping area 160, achieving a quick "alignment and locking" connection. This effectively alleviates the drawbacks of traditional devices that require repeated calibration and alignment, improving operational efficiency. Furthermore, the curved surface design of the double arc-shaped surfaces on both sides of the opening 161 ensures at least three points of contact constraint with the outer wall of the second endoscope 300 in the clamping state. While ensuring clamping stability, this contact mode, through the extension characteristics of the arc-shaped surfaces, allows the second endoscope 300 to rotate circumferentially around its own axis, and achieves fine-tuning of the pitch angle by utilizing the tilt angle tolerance between the curved surfaces. This dual adjustment mechanism enables the first endoscope 200 and the second endoscope 300 to coordinate and adjust their relative positions in real time during the operation, meeting the dynamic requirements of multi-scope collaborative operation for complex surgical procedures.

[0057] Please refer to it again. Figure 2 In Embodiment 1, the clamp 120 is generally U-shaped, with the first clamping component 130 and the second clamping component 140 forming the two sides of the U-shaped structure. The clamp 120 also includes a connecting structure 150, which is the middle part of the U-shaped structure. The connecting structure 150 is disposed between the first clamping component 130 and the second clamping component 140 and is connected to both components. Furthermore, the connecting structure 150 is also connected to the base 110, thereby connecting the base 110 and the clamp 120 to form an integral structure.

[0058] It is understood that in some embodiments, the first clamping component 130 and the second clamping component 140 of the clamp 120 can also be directly connected to the base 110. That is, the clamp 120 may not have the above-mentioned connection structure 150, but can directly connect to the base 110 through its first clamping component 130 and the second clamping component 140 to form an integral structure.

[0059] In Embodiment 1, the first clamping assembly 130 includes a first clamping arm 131 and a first guide portion 132. The first guide portion 132 is disposed at the end of the first clamping arm 131 away from the base 110, and the first guide portion 132 has a first arcuate surface 133. The second clamping assembly 140 includes a second clamping arm 141 and a second guide portion 142. The second guide portion 142 is disposed at the end of the second clamping arm 141 away from the base 110, and the second guide portion 142 has a second arcuate surface 143.

[0060] The end of the first clamping arm 131 furthest from the base 110 is the first free end 135, which is also the end of the first clamping arm 131 furthest from the connecting structure 150. A first guide portion 132 is connected to the first free end 135 and protrudes from the first free end 135 toward the second clamping arm 141. Specifically, the first free end 135 has a first mounting portion 134 extending from the first free end 135 toward the side closest to the second clamping arm 141. The first guide portion 132 is rotatably connected between the two first mounting portions 134 via its rotation axis, thereby forming a roller structure that can rotate around its rotation axis, or it can also be called a rotating roller structure. The first arcuate surface 133 is the arcuate surface of this roller structure facing the side where the second clamping arm 141 is located.

[0061] The end of the second clamping arm 141 furthest from the base 110 is the second free end 145, which is also the end of the second clamping arm 141 furthest from the connecting structure 150. A second guide portion 142 is connected to the second free end 145 and protrudes from the second free end 145 toward the first clamping arm 131. Specifically, the second free end 145 is provided with a second mounting portion 144, which extends from the second free end 145 of the second clamping arm 141 toward the side closer to the first clamping arm 131. The second guide portion 142 is rotatably connected between the two second mounting portions 144 via its rotation axis, thereby forming a roller structure that can rotate around its rotation axis, or it can also be called a rotating roller structure. The second arcuate surface 143 is the arcuate surface of this roller structure facing the first clamping arm 131.

[0062] Therefore, when the second endoscope 300 is inserted, the first guide portion 132 and the second guide portion 142 can rotate, guiding the second endoscope 300 to quickly slide to the center of the clamping area 160, thereby enabling rapid and accurate connection. Correspondingly, it can also be removed from the clamping area 160 more quickly, facilitating decoupling of the second endoscope 300 from the first endoscope 200 and improving operational efficiency. Furthermore, since both the first guide portion 132 and the second guide portion 142 can rotate, the second endoscope 300 can be more easily adjusted in multiple angles.

[0063] In Embodiment 1, the first clamping arm 131 and the second clamping arm 141 extend in a straight line. That is, the first clamping arm 131 extends in a straight line from its first fixed end 136 to its first free end 135, and the second clamping arm 141 extends in a straight line from its second fixed end 146 to its second free end 145. The first fixed end 136 is the end of the first clamping arm 131 closest to the base 110, which is the end of the first clamping arm 131 connected to the connecting structure 150. The second fixed end 146 is the end of the second clamping arm 141 closest to the base 110, which is the end of the second clamping arm 141 connected to the connecting structure 150. When the first free end 135 and the second free end 145 are compressed and moved by the second endoscope 300, the ends of the first clamping arm 131 and the second clamping arm 141 closest to the base 110 remain almost fixed relative to the base 110, or only vibrate slightly. Specifically, "extending along a straight line" means that, under natural unloaded conditions, the geometric center line of the main structure of each clamp arm is in a continuous straight line from one end (defined as the fixed end, which is rigidly connected to the base 110 or the connecting structure 150) to the other end (defined as the free end, which can generate displacement in response to external loads), and the displacement of the fixed end relative to the base 110 is less than 5% of the maximum displacement of the free end; when the free end is subjected to external force, the connection area between the fixed end and the base 110 or the connecting structure 150 maintains a locked position or undergoes only slight elastic deformation within a preset tolerance range, so as to ensure that the overall movement of the component is based on the straight extension direction as the reference axis.

[0064] It should be noted that in some embodiments, the first clamping arm 131, the second clamping arm 141, and the connecting structure 150 are integrally formed, with no obvious visible seams or transition structures between them. The connecting structure 150 may be arc-shaped and have a generally continuous and smooth arc-shaped profile. The first clamping arm 131 and the second clamping arm 141 extend in a straight line from their connection areas with the connecting structure 150 along the tangent direction of the arc-shaped profile of the connecting structure 150.

[0065] By configuring the first clamping arm 131 and the second clamping arm 141 to extend in a straight line, when the second endoscope 300 is inserted or removed, the first guide portion 132 and the second guide portion 142 will be subjected to the squeezing force from the second endoscope 300 and transmitted to the first clamping arm 131 and the second clamping arm 141, which can make the first clamping arm 131 and the second clamping arm 141 move more freely, thereby making it easier to install or remove the second endoscope 300.

[0066] In Embodiment 1, the distance between the first free end 135 and the second free end 145 is smaller than the distance between the first fixed end 136 and the second fixed end 146. That is, the clamping area 160 generally increases in size from its opening 161 inwards, making it easier to install the second endoscope 300 into the clamping area 160. Furthermore, a portion of the clamping force exerted by the first clamping arm 131 and the second clamping arm 141 on the second endoscope 300 points towards the base 110, thus securing the second endoscope 300 more stably.

[0067] In Embodiment 1, the clamp 120 also includes a support pad 170, which is detachably connected to the side of the connecting structure 150 facing the clamping area 160. The support pad 170 enhances the stability of the support for the second endoscope 300. Furthermore, the support pad 170 has a detachable structure, facilitating replacement of parts. Different models of support pads 170 can be used to adjust the size of the clamping area 160 to accommodate different models of the second endoscope 300. Specifically, a slot can be provided on the connecting structure 150, and the support pad 170 can be fitted into the slot with a suitable structure. Alternatively, other suitable structures can be provided for easy disassembly. The support pad 170 can be configured as an elastic support structure, which better conforms to the second endoscope 300 and facilitates adjustment of the position of the second endoscope 300.

[0068] In some embodiments, the clamp 120 does not have a connecting structure 150, and the first clamping component 130 and the second clamping component 140 are directly connected to the base 110. Correspondingly, the support pad 170 can also be directly placed on the base 110, which can also produce the above-mentioned effect.

[0069] Please refer to the following: Figure 3 and Figure 4In Embodiment 2, the structure of the endoscope attachment device 100 is largely the same as that in Embodiment 1, except that: in Embodiment 2, the first clamping arm 131 extends along an arc from its first fixed end 136 to its first free end 135; and the second clamping arm 141 extends along an arc from its second fixed end 146 to its second free end 145. This arrangement allows for a larger clamping area 160, facilitating adjustment of the position and orientation of the second endoscope 300. Of course, in some other embodiments, one of the first clamping arm 131 and the second clamping arm 141 may be configured to extend along an arc, while the other may be configured to extend along a straight line; or the first clamping arm 131 and the second clamping arm 141 may be configured the same as in Embodiment 1, both extending along a straight line.

[0070] Specifically, the extension along the arc is manifested as follows: the geometric center line of the clamping arm, from the fixed end (rigidly connected to the base 110 or the connecting structure 150) to the free end, is an arc with a radius of curvature varying within a preset range, and the plane containing this arc is perpendicular to the mounting surface of the base 110. When the free end is subjected to external force, the clamping arm elastically deflects around the center of curvature of the arc as the instantaneous center of rotation, while maintaining the geometric characteristics of the arc extension.

[0071] Furthermore, in Embodiment 2, the first clamping assembly 130 is also provided with a first protrusion 137 connected to the first clamping arm 131, and the first protrusion 137 is disposed on the side of the first clamping arm 131 facing the clamping area 160; the second clamping assembly 140 is provided with a second protrusion 147 connected to the second clamping arm 141, and the second protrusion 147 is disposed on the side of the second clamping arm 141 facing the clamping area 160. By providing the first protrusion 137 and the second protrusion 147, the second endoscope 300 can be supported and clamped more stably, and the friction can also be increased, making the second endoscope 300 more securely installed.

[0072] Furthermore, in Embodiment 2, the first guide portion 132 is connected to the end of the first clamping arm 131 away from the base 110, i.e., connected to the first free end 135, and protrudes from the first free end 135 toward the second clamping arm 141. The second guide portion 142 is connected to the end of the second clamping arm 141 away from the base 110, i.e., connected to the second free end 145, and protrudes from the second free end 145 toward the first clamping arm 131. Specifically, as... Figure 4As shown, the first guide portion 132 has a first mating surface 138 facing away from the first arcuate surface 133, and the first mating surface 138 covers the first free end 135; the second guide portion 142 has a second mating surface 148 facing away from the second arcuate surface 143, and the second mating surface 148 covers the second free end 145. The first guide portion 132 can be directly fixed to the first free end 135 of the first clamping arm 131 by means of bonding or the like, and the second guide portion 142 can also be directly fixed to the second free end 145 of the second clamping arm 141 by means of bonding or the like.

[0073] Please refer to the following: Figure 5 and Figure 6 In Embodiment 3, the structure of the endoscope attachment device 100 is roughly the same as that of Embodiments 1 and 2. The first clamping arm 131 and the second clamping arm 141 in Embodiment 3 also extend along a straight line, similar to Embodiment 1 but different from Embodiment 2.

[0074] Furthermore, in Embodiment 3, although a first protrusion 137 and a second protrusion 147 are also provided, their shapes are slightly different from those in Embodiment 2, which can more stably support and clamp the second endoscope 300, increase friction and make the second endoscope 300 more securely installed.

[0075] Furthermore, in Embodiment 3, the first clamping arm 131 and the first guide portion 132 are integrally formed, as are the second clamping arm 141 and the second guide portion 142. That is, the first guide portion 132 and the first clamping arm 131 are integrally formed, with the first guide portion 132 protruding from the first free end 135 toward the second clamping arm 141; the second guide portion 142 and the second clamping arm 141 are integrally formed, with the second guide portion 145 protruding from the second free end 145 toward the first clamping arm 131. This arrangement reduces processing steps, facilitates manufacturing, ensures structural integrity, and extends service life.

[0076] Furthermore, in Embodiment 3, the distance between the first clamping assembly 130 and the second clamping assembly 140 decreases in the axial direction of the clamp 120 from one end to the other. Please refer to [link / reference]. Figure 5 The axial direction of the clamp 120 is Figure 5 The vertical direction refers to the length direction of the second endoscope 300. In the axial direction, from the upper end to the lower end of the clamping seat 120, the distance between the first clamping assembly 130 and the second clamping assembly 140 is reduced. This can better adapt to the shape of the second endoscope 300, improve the stability of clamping, and ensure a more secure attachment.

[0077] Please see Figure 7In another embodiment of Example 3, the first clamping assembly 130 further includes a first flexible portion 139, which is disposed on the side of the first guide portion 132 facing the clamping area 160 and connected to the first guide portion 132; the second clamping assembly 140 further includes a second flexible portion 149, which is disposed on the side of the second guide portion 142 facing the clamping area 160 and connected to the second guide portion 142. By providing the first flexible portion 139 inside the first guide portion 132 and the second flexible portion 149 inside the second guide portion 142, rigid wear on the second endoscope 300 can be reduced, and the clamping stability of the second endoscope 300 can be improved.

[0078] Please refer to the following: Figure 8 and Figure 9 In Embodiment 4, the structure of the endoscope attachment device 100 is largely the same as that of Embodiments 1, 2, and 3, with the difference being that: in Embodiment 4, the first guide portion 132 extends in an arc shape from the end of the first clamping arm 131 away from the base 110; the second guide portion 142 extends in an arc shape from the end of the second clamping arm 141 away from the base 110. Specifically, during manufacturing, the first clamping arm 131 and the second clamping arm 141 are bent inward to form an arc shape, thereby forming the first guide portion 132 and the second guide portion 142, respectively.

[0079] In Embodiment 4, the first clamping arm 131 and the first guide portion 132 can be configured as an integral structure, and the second clamping arm 141 and the second guide portion 142 can be configured as an integral structure. Alternatively, the first clamping arm 131 and the first guide portion 132 can be configured as separate structures, and the second clamping arm 141 and the second guide portion 142 can be configured as separate structures. For example, after bending the first clamping arm 131 and the second clamping arm 141 inward to form an arc-shaped structure, the first guide portion 132 and the second guide portion 142 can be attached to the surface of the arc-shaped structure.

[0080] like Figure 1 , Figure 3 , Figure 5 and Figure 8 As shown, this application embodiment also provides an endoscope kit, which includes an endoscope attachment device 100 of any of the above embodiments, as well as a first endoscope 200 and a second endoscope 300. The base 110 of the endoscope attachment device 100 is attached to the first endoscope 200, and the second endoscope 300 can be accommodated in the clamping area 160 of the endoscope attachment device 100 to be clamped and fixed by the first clamping component 130 and the second clamping component 140 of the endoscope attachment device 100.
