Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a basket control bracket, a basket assembly, and an endoscope kit. Background Technology

[0002] A basket device is a commonly used medical instrument, primarily used in urological surgeries to remove stones from the ureter or renal pelvis. Its working principle involves inserting a basket into the target area through the working channel of an endoscope, grasping the stone, and then smoothly removing it from the body. Basket devices offer advantages such as ease of operation, minimal trauma, and rapid recovery, and are widely used in minimally invasive urological surgeries.

[0003] The existing basket controller for basket devices is installed on the operating handle of the endoscope, allowing a single person to cover the operation needs of both the basket device and the endoscope. However, in practice, it has been found that the basket controller cannot be adapted to the control components on the endoscope due to interference, resulting in poor applicability of the basket controller. Utility Model Content

[0004] In view of the shortcomings of the above-mentioned related technologies, this application provides a basket control bracket, a basket assembly, and an endoscope kit to solve the above-mentioned technical problems.

[0005] This application provides a basket control bracket for use with an endoscope. The basket control bracket has a lever adapted to drive a basket device to control the tightening or unfolding of the stone retrieval basket of the basket device. The basket control bracket is provided with a mounting part adapted to be mounted on the operating handle of the endoscope. The basket control bracket is configured such that, when mounted on the proximal end of the operating handle of the endoscope via the mounting part, the lever is offset relative to the control area of ​​the operating handle in the width direction of the endoscope.

[0006] To achieve the above and other related objectives, this application provides a basket assembly, which includes the aforementioned basket control bracket and basket device. The basket device has a stone-collecting basket, and a lever is connected to the basket device to control the tightening or unfolding of the stone-collecting basket.

[0007] To achieve the above and other related objectives, this application provides an endoscope kit, which includes the aforementioned basket assembly and an endoscope. The endoscope has an operating handle, and a mounting portion is fitted onto the operating handle.

[0008] The technical solution adopted in this utility model achieves the following beneficial effects: the lever can drive the basket device to control the tightening or unfolding of the stone retrieval basket. The basket control bracket is provided with a mounting part, which can be mounted on the operating handle. The lever is offset from the control area in the width direction of the endoscope. The control area refers to the area occupied by the endoscope's control components and the area required to operate these components; the control components can be a shooting button, a negative pressure suction valve, etc. The lever being offset from the control area avoids interference between the lever and the control area, allowing the operation of the lever and the endoscope's control components to be relatively independent and both to be operated smoothly. This design facilitates the adaptation of the basket control bracket to endoscopes with control areas, improving the applicability of the basket control bracket.

[0009] Furthermore, when medical staff hold the endoscope, their fingers extend in a direction roughly parallel to the width of the endoscope. When switching between levers and control areas, only the fingers need to be moved slightly in the width direction; there is no need to move the palm in the length direction. This width-oriented operation is faster and facilitates one-handed operation for medical staff. Attached Figure Description

[0019] 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.

[0020] 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.

[0021] 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".

[0022] However, in practice, it has been found that when the basket controller is installed on the endoscope, the lever of the basket controller and the control components on the endoscope may interfere with each other. This can cause the other to be accidentally activated when one of the levers or control components is operated. As a result, the basket controller cannot be adapted to endoscopes with existing control components, leading to poor applicability of the basket controller.

[0023] This application provides a basket control bracket 110; please refer to [link / reference]. Figure 1The basket control bracket 110 is used for endoscope 2.

[0024] Please see Figure 1 as well as Figure 2 The basket control bracket 110 has a lever 112, which is adapted to drive the basket device 130 to control the tightening or unfolding of the stone retrieval basket of the basket device 130. In other words, the basket control bracket 110 transmits power to the basket device 130 via the lever 112 to control the stone retrieval basket of the basket device 130. For example, the basket device 130 has a stone retrieval basket and a sleeve mounted on the basket control bracket 110. The stone retrieval basket can be inserted into the human body cavity through the instrument channel of the endoscope 2. The basket control bracket 110 can control the basket device 130. The stone retrieval basket has a mesh structure. Under the control of the basket control bracket 110, the stone retrieval basket tightens while simultaneously grasping the object to be removed, thus achieving a grasping operation. Medical personnel remove the stone retrieval basket to remove the object. The object to be removed can be a lesion, a stone, etc., and is not limited thereto. A sleeve can be mounted on the stone retrieval basket control bracket 110. A push rod is inserted inside the sleeve, connected to the stone retrieval basket, with both ends extending outside the sleeve. A lever 112 can drive the push rod to move relative to the sleeve, controlling the stone retrieval basket to switch between a tightened and unfolded state. Medical personnel can place the unfolded stone retrieval basket around the object to be removed, and switch the basket to the tightened state using the push rod. The tightened basket can grasp the object to be removed, and the medical personnel can then remove the basket to take the object away. Of course, the stone retrieval basket can also perform other functions, which are not listed in this application.

[0025] In a more specific implementation, please refer to Figure 3 as well as Figure 4The net basket control bracket 110 also includes a transmission rod 113, a drive wheel 114, a driven wheel 115, and a rack 116. The transmission rod 113 is fixedly connected between the lever 112 and the drive wheel 114. Driven by the lever 112, the transmission rod 113 drives the drive wheel 114 to rotate around the axis of the transmission rod 113. The driven wheel 115 is driven between the drive wheel 114 and the rack 116. When the drive wheel 114 rotates, it drives the driven wheel 115 to rotate and also drives the rack 116 to move. The rack 116 is connected to the net basket device 130. When the rack 116 is driven, it causes the stone-collecting net basket of the net basket device 130 to tighten or expand. One end of the transmission rod 113 is fixedly connected to the lever 112, and the other end is connected to the drive wheel 114. For example, when the operator rotates lever 112, lever 112 drives transmission rod 113 to rotate around its own axis, and the driving wheel 114 connected to transmission rod 113 will also rotate synchronously around the same axis. The driving wheel 114 is connected to the driven wheel 115 through gear meshing or belt drive, and the driven wheel 115 rotates according to the corresponding transmission ratio. The rotation of the driven wheel 115 is converted into the linear motion of rack 116. Since rack 116 is connected to the basket device 130, when rack 116 moves linearly under the drive of driven wheel 115, it directly drives the push rod of basket device 130 to move relative to each other. This causes the stone retrieval basket to shrink, achieving the tightening action. Under the drive of lever 112, when rack 116 moves in the opposite direction, the support structure of the stone retrieval basket will move away from each other under its own elasticity or the push of rack 116, causing the stone retrieval basket to expand, completing the unfolding action. This stone-retrieving basket, which tightens and expands through multi-stage transmission, can precisely adapt to the size and shape of the object to be removed, ensuring the reliability of the basket when grabbing and moving the object.

[0026] In the embodiments of this application, please refer to Figure 2 as well as Figure 3The basket control bracket 110 is provided with a mounting part 111, which is adapted to be mounted on the operating handle 120 of the endoscope 2. The basket control bracket 110 is configured such that, when mounted on the proximal end of the operating handle 120 of the endoscope 2 via the mounting part 111, the lever 112 is offset relative to the control area 121 in the width direction of the endoscope 2. Offset in the width direction means that the lever 112 and the control area 121 do not overlap in the same width direction. The control area 121 refers to the area occupied by the control element 1211 of the endoscope 2 and the area required to operate the control element 1211, etc. The control element 1211 can be a shooting button, a negative pressure suction valve, etc. The lever 112 being offset from the control area 121 avoids interference between the lever 112 and the control area 121, allowing the operation of the lever 112 and the control element 1211 of the endoscope 2 to be relatively independent and both to be operated smoothly. This configuration facilitates the adaptation of the basket control bracket 110 to the endoscope 2 with the control area 121, thereby improving the applicability of the basket control bracket 110.

[0027] Understandably, in the width direction of endoscope 2 (e.g.) Figure 1 The staggered arrangement (as shown in L1) facilitates operation by medical staff. This is because the endoscope 2 is configured with a slender structure for easy gripping and operation. When medical staff hold the endoscope 2, the direction of their finger extension is roughly parallel to the width direction of the endoscope 2. When switching between the lever 112 and the control area 121, they only need to move their fingers slightly in the width direction, without needing to move them in the length direction (e.g., as shown in L1). Figure 1 As shown in L2, moving the palm upwards makes switching operations in the width direction faster and also facilitates one-handed operation for medical staff.

[0028] In one implementation, please refer to Figure 1The mounting portion 111 and the lever 112 are offset from each other in the width direction of the basket control bracket 110. The mounting portion 111 allows the basket control bracket 110 to be assembled with the endoscope 2, which facilitates the fixation of the endoscope 2 and the basket control bracket 110. The mounting portion 111 is mounted on the proximal end of the operating handle 120. The area of ​​the operating handle 120 suitable for mounting the mounting portion 111 and the control area 121 are distributed along the axis of the endoscope 2, that is, along the length direction of the endoscope 2. The mounting portion 111 and the lever 112 are offset from each other in the width direction of the basket control bracket 110, which also allows the lever 112 to be offset in the width direction of the control area 121. Understandably, the basket control bracket 110 is installed in the area adjacent to the control area 121 via the mounting part 111, and is distributed along the axis of the endoscope 2 with the control area 121. This also reduces the operating range, avoids the situation where medical staff have to extend their fingers for too long, resulting in poor operating feel, improves the integration of the basket control bracket 110 on the endoscope 2, and at the same time avoids the flicking effect of the basket control bracket 110 in the broadband direction.

[0029] In another implementation, please refer to Figure 5The basket control bracket 110 may further include a housing 117, within which the transmission rod 113, drive wheel 114, driven wheel 115, and rack 116 are all housed. The housing 117 provides protection against external dust and other contaminants. The mounting portion 111 has a mounting groove 1111, the extension direction of which is collinear or parallel to the length direction of the operating handle 120. The mounting groove 1111 is adapted to fit onto the proximal end of the operating handle 120. The mounting groove 1111 and the proximal end of the operating handle 120 are compatible in terms of shape and size. The mounting groove 1111 allows the basket control bracket 110 to be stably mounted on the operating handle 120, facilitating one-handed operation by medical personnel. When the mounting groove 1111 is mounted on the proximal end of the operating handle 120, its extension direction is parallel or collinear with the length direction of the operating handle 120. The housing 117 has an opening 1171, and the lever 112 extends out of the housing 117 through the opening 1171. The opening 1171 and the mounting groove 1111 are offset from each other in the width direction of the mounting groove 1111. This provides a stable foundation for subsequent operations. The offset layout of the opening 1171 and the mounting groove 1111 in the width direction allows the lever 112 and the mounting part 111 to also be offset from each other in the width direction. This offset setting in the width direction can avoid the lever 112 and the mounting part 111 from overlapping or interfering with each other in space. When the operator holds the operating handle 120, the mounting part 111 is fitted onto the near end of the operating handle 120, while the lever 112 is offset from the operating handle 120 in the width direction. This prevents the operation of one of them from being too close and interfering with the other. It ensures both the stable installation of the mounting part 111 on the device and the smooth operation of the lever 112, making the operation of the basket control bracket 110 more convenient and efficient.

[0030] In the embodiments of this application, please refer to Figure 6The lever 112 has a connecting end 1121 and a free end 1122 that are far apart from each other. The connecting end 1121 is adapted to drive the stone retrieval basket, and the free end 1122 extends out of the housing 117 of the basket control bracket 110 and is offset relative to the control area 121 in the width direction of the endoscope 2. The connecting end 1121 and the free end 1122 are bent toward the same side, and a bending space 1123 is formed between the connecting end 1121 and the free end 1122. In other words, the opposite ends of the lever 112 are bent toward the same side, and a bending space 1123 is formed between the opposite ends of the lever 112. The projection of the control area 121 of the operating handle 120 along the width direction of the endoscope 2 is located within the bending space 1123. The projection of the control area 121 and its control component 1211 along the width direction of the endoscope 2 is located within the bending space 1123. The setting of the bending space 1123 can avoid obstructing the control area 121 and its control component 1211 in the width direction. The fingers of medical staff can be inserted into the control area 121 through the bending space 1123, ensuring that the control area 121 and its control component 1211 can be touched by the fingers. This further avoids interference between the lever 112 and the control area 121, so that the operation of the lever 112 and the control component 1211 of the endoscope 2 is relatively independent.

[0031] Please continue reading. Figure 6 The connecting end 1121 of the lever 112 is provided with at least two mounting portions 111. The number of mounting portions 111 can be two, three, or even more, and is not limited here. For example, the mounting portions 111 may have mounting holes that allow the basket control bracket 110 to connect with each other. Furthermore, the mounting holes can be fitted onto the transmission rod 113 and fixedly connected to it. At least two mounting portions 111 are distributed vertically, and each mounting portion 111 is detachably mounted on the basket control bracket 110. The lever 112 is mounted on the basket control bracket 110 through different mounting portions 111 to adjust the relative height of the lever 112. The vertical direction can be perpendicular to the width and length directions of the endoscope 2, i.e., the height direction of the endoscope 2. By adjusting the relative height of the lever 112, it is ensured that the fingers of medical staff can be inserted into the control area 121, avoiding interference of the lever 112 with the control area 121 in the width direction, and also avoiding excessive height difference between the lever 112 and the control area 121, which would affect the efficiency of operation.

[0032] Of course, in some other cases, the distribution direction of at least two mounting parts 111 can have an appropriate angle with the vertical direction, such as 5°-20°, to adapt to different operating habits, and there is no restriction.

[0033] In this embodiment, the operating handle 120 has a grip portion 122, which is a part of the operating handle 120 suitable for gripping and operation. Furthermore, the grip portion 122 and the control area 121 can be distributed along the length of the endoscope 2. When the hand fully grasps the grip portion 122, the control area 121 is within the range of finger movement, which facilitates control by medical personnel. The free end 1122 is adapted to extend to the periphery of the grip portion 122, which shortens the operator's operating range and prevents the free end 1122 from being set too far away, making single-handed operation impossible. In addition, the distribution of the grip portion 122 and the control area 121 along the length of the endoscope 2 also allows the free end 1122 to be offset from the control area 121 along the length of the endoscope 2, further preventing interference between the lever 112 and the control area 121.

[0034] The free end 1122 is located on the central axis surface of the operating handle 120. For example, the lever 112 can be bent along the width direction of the endoscope 2 so that the free end 1122 is located on the central axis surface of the operating handle 120. This central axis surface can pass through the central axis of the operating handle 120 and be perpendicular to the width direction of the endoscope 2. In this case, by extending to the periphery of the grip portion 122, the free end 1122 and the control area 121 are not in the same width direction. When the operator's fingers naturally rest on the operating handle 120, the central axis surface is often the central area for finger force and movement. The free end 1122 being located here allows the fingers to contact it in the most natural and effortless manner. Whether pressing or flicking the free end 1122, the fingers do not need to deliberately adjust the angle or position to accurately apply force, reducing the range of motion and force consumption during operation. This layout, which conforms to the natural operating habits of the fingers, is ergonomically designed, thus significantly improving the convenience and efficiency of finger operation.

[0035] Preferably, the free end 1122 is provided with a ring-shaped structure. The ring-shaped structure on the free end 1122 of the lever 112 allows medical personnel to pass their fingers through the ring-shaped structure and hold the endoscope 2 when operating the basket control support 110. The ring-shaped structure follows the finger's movement; it can be controlled by the finger's lifting or pressing motion. When operation is required, the net basket control support 110 is operated by moving the ring-shaped structure with the finger.

[0036] Of course, in some other cases, the basket control bracket 110 is equipped with a reset element, which can be a spring or a spring sheet, etc., and is not limited thereto. The reset element is connected to the lever 112, which can be a rod. When the lever 112 is pressed down, it controls the tightening of the stone retrieval basket, and the reset element deforms with the movement of the lever 112. When medical staff release the lever 112, the reset element can drive the lever 112 to reset, which will not be elaborated here.

[0037] To achieve the above and other related objectives, this application provides a basket assembly 100. Please refer to [link to relevant documentation]. Figure 7 The system includes the aforementioned basket control bracket 110 and basket assembly 130. The basket assembly 130 has a stone-collecting basket, and a lever 112 is connected to the basket assembly 130 to control the tightening or unfolding of the stone-collecting basket. This gives the basket assembly 100 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here.

[0038] To achieve the above and other related objectives, this application provides an endoscope kit 1, please refer to [link to relevant documentation]. Figure 7 The endoscope kit 1 includes the aforementioned basket assembly 100 and endoscope 2. Endoscope 2 has an operating handle 120, and the mounting portion 111 of the basket assembly 100 is fitted onto the operating handle 120. This gives endoscope kit 1 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here. Endoscope 2 can be a bronchoscope, pyeloscope, esophagoscope, gastroscope, colonoscope, otoscope, rhinoscope, oral endoscope, laryngoscope, colposcope, laparoscope, arthroscope, etc. This application embodiment does not specifically limit the type of endoscope 2.

[0039] The operating handle 120 may also include a control element 1211 installed in the control area 121. The control element 1211 can be a shooting button, a negative pressure suction valve, etc., and is not limited thereto. Along the width direction of the endoscope 2, the control element 1211 is correspondingly arranged with the bending space 1123 of the basket control bracket 110. The bending space 1123 is formed by bending the opposite ends of the lever 112 towards the same side and between the opposite ends of the lever 112. The way in which the control element 1211 and the bending space 1123 of the basket control bracket 110 are correspondingly arranged allows the fingers of medical personnel to be inserted into the control area 121 through the bending space 1123, ensuring that the control area 121 and its control element 1211 can be touched by the fingers, further avoiding interference between the lever 112 and the control area 121, so that the operation of the lever 112 and the control element 1211 of the endoscope 2 is relatively independent.

[0040] 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. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
