Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical surgical equipment technology, specifically to a multi-purpose front end head for an electronic renal pelvis endoscope, and also to an electronic renal pelvis endoscope. Background Technology
[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It can be inserted into the human body through natural orifices or through small surgical incisions. Endoscopes can be used to see lesions that cannot be detected by X-rays. Therefore, it is a commonly used medical device in hospitals and by doctors during surgery.
[0003] The specialized electronic renal pelvis endoscope in this patent is a commonly used surgical device in urology, used in interventional procedures for kidney lithotripsy, stone removal, and other scenarios. A typical endoscope includes a tube and an operating handle. The tube contains a light guide, cable, cleaning tube, and instrument channel. The end of the tube is equipped with... Figure 4 The endoscope tube 10 shown has a lens hole for the endoscope lens to protrude and a mechanical hole for the surgical mechanism to protrude. However, due to the requirements of minimally invasive surgery, the endoscope tube 10 has strict size requirements. If the radial dimension of the end is too large, it will cause strong discomfort to the patient. Therefore, the endoscope tube is required to have a relatively small size. This situation causes the hole structures that realize different functions on the end face of the endoscope tube to be concentrated, which can easily lead to mutual interference and affect their respective functions. In particular, when the surgical mechanical mechanism protrudes from the endoscope end hole structure, the protruding mechanical structure can easily block the endoscope lens's field of view and affect surgical observation.
[0004] In addition, for pyeloscopy itself, intrarenal pressure monitoring is an important step in the procedure. However, intrarenal pressure monitoring requires the introduction of an additional independent probe, which is a complicated procedure that prolongs the operation time and poses a risk of cross-infection.
[0005] In summary, the existing design of renal pelvis endoscopes has technical problems such as the susceptibility of surgical observation to problems and the cumbersome operation process that may lead to infection risks. Utility Model Content
[0006] The technical problem to be solved by this utility model is that the existing design of the renal pelvis endoscope is easily affected during surgical observation, and the operation is cumbersome and prone to infection.
[0007] To address the aforementioned problems, this utility model provides a multi-purpose tip for an electronic pyeloscope, comprising a hollow cylindrical tip housing, with an end plate integrally connected to one end of the tip housing; the end plate includes an integrally connected vertical plate and an inclined plate, the vertical plate being perpendicular to the axial direction of the tip housing and having a lens hole thereon, the inclined plate forming an angle of less than 90° with the axis of the tip housing and having a mechanical hole thereon; a pressure measuring hole is provided on the outer peripheral wall of the tip housing near the end plate, the pressure measuring hole being used to insert a pressure measuring probe.
[0008] This utility model provides a renal pelvis endoscope tip design that optimizes and improves the front-end plate structure for operation based on the traditional design. It replaces the typical flat plate design with a bent, two-part plate structure. The plate portion perpendicular to the central axis of the end-end housing is used to house the lens hole, aligning the lens parallel to the end-end housing. The mechanical hole for the surgical mechanism is located on an inclined plate with a certain angle. Thus, during surgery, when the mechanical mechanism passes through the mechanical hole, the inclination of the plate and the mechanical hole keeps the mechanical mechanism away from the lens, effectively preventing the mechanical mechanism from obstructing the lens. This design ensures complete and effective imaging of the lens. A pressure-measuring hole is provided on the outer peripheral wall of the end-end housing for inserting a pressure-measuring probe. This allows the pressure-measuring probe to be directly integrated into the end-end of the endoscope, providing real-time pressure data without the need for a mechanical hole. When necessary, the mechanical structure can be removed and replaced with the pressure-measuring probe, effectively simplifying the surgical procedure and avoiding the possibility of cross-infection caused by pressure measurement. This effectively solves the technical problems of existing nephropyoscope designs, such as susceptibility to interference with surgical observation and cumbersome operation that increases the risk of infection.
[0009] As a preferred embodiment, the angle between the inclined plate and the axis of the end housing is in the range of 40°-50°. This design further optimizes the design of the inclined plate by limiting the range of the angle between the inclined plate and the axis of the end housing. When the angle is between 40°-50°, or around 45°, the mechanical structure can maximize its avoidance of the camera's field of view.
[0010] As a preferred embodiment, the angle between the axis of the mechanical hole and the axis of the lens hole ranges from 15° to 30°. This design optimizes the angle of the mechanical hole. Based on the aforementioned inclined plate structure, the inclination angle of the mechanical hole is specifically optimized, with the hole direction forming a 15°-30° angle with the lens direction. This effectively avoids obstructing the camera's field of view and optimizes the insertion effect of the mechanical mechanism, ensuring that the mechanical structure can smoothly pass through the mechanical hole.
[0011] As a preferred embodiment, the outer peripheral wall of the end cap housing has two pressure measurement holes on the side near the end plate. The two pressure measurement holes are distributed 180° apart on the outer peripheral wall of the end cap housing, and a pressure measurement probe is inserted into each pressure measurement hole. This design further optimizes the design of the pressure measurement holes. The structure of two pressure measurement holes with opposite orientation can eliminate possible positional errors when the endoscope tip is inserted. In addition, it should be noted that the end of the pressure measurement probe extends about 0.2 mm outside the pressure measurement hole, and the pressure sampling frequency is greater than 200 Hz.
[0012] As a preferred embodiment, the outer peripheral wall of the end cap has a stepped surface structure at one end near the end plate. This stepped surface structure is used for insertion with the endoscope tube. All pressure measurement holes are located at the radially larger end of the outer peripheral wall on one side of the stepped surface structure. This design optimizes the position of the pressure measurement holes on the outer wall of the end cap. The stepped surface structure facilitates insertion and positioning with the endoscope tube, and the placement of the pressure measurement holes at the radially larger end of the outer peripheral wall on one side of the stepped surface structure ensures that the pressure measurement probe protrudes to the outermost side of the end cap, guaranteeing effective pressure measurement.
[0013] As a preferred embodiment, the lens aperture is square-shaped, and the inner wall of the end housing is provided with a stepped limiting structure that communicates with the side wall of the lens aperture. This design optimizes the structure of the lens aperture by using a square aperture and providing a stepped surface structure on the inner wall of the aperture, which facilitates concave-convex positioning with the outer contour of the lens.
[0014] As a preferred embodiment, the transition area between the vertical plate and the inclined plate has a rounded edge structure. This design is suitable for the overall structure of the end plate, which consists of two parts. The transition area between the vertical and inclined plates has rounded edges instead of sharp corners, thus preventing injury to the patient during surgery.
[0015] This utility model also provides an electronic pyeloscope, including an endoscope handle assembly and an endoscope tube, the end of which is connected to an endoscope tip, wherein the endoscope tip is a multi-purpose tip for an electronic pyeloscope as described above. Since the aforementioned multi-purpose tip for an electronic pyeloscope has the above-mentioned beneficial effects, an electronic pyeloscope having this multi-purpose tip should also possess corresponding beneficial effects.

Detailed Implementation
[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] Before providing a detailed explanation of the working principle of this utility model, further clarification is needed regarding its description: In this description, terms such as "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, an indirect connection through an intermediate medium, or a welded connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] refer to Figures 1-3 The following examples illustrate this. Figure 1 A schematic diagram of the structure of a multi-purpose front end head for an electronic nephroptoscope provided by this utility model; Figure 2 for Figure 1 A side view structural diagram of the multi-purpose tip head used in an electronic nephroptoscope; Figure 3 for Figure 1 A schematic diagram of the structure on the other side of the multi-purpose tip of the electronic nephroptoscope.
[0021] This embodiment provides a multi-purpose tip for an electronic pyeloscope, including a hollow cylindrical tip housing 1, with an end plate 2 integrally connected to one end of the tip housing 1; the end plate 2 includes an integrally connected vertical plate 2-1 and an inclined plate 2-2, the vertical plate 2-1 being perpendicular to the axial direction of the tip housing 1 and having a lens hole 3 thereon, the inclined plate 2-2 forming an angle of less than 90° with the axis of the tip housing 1, and having a mechanical hole 4 thereon; a pressure measuring hole 5 is provided on the outer peripheral wall of the tip housing 1 near the end plate 2, the pressure measuring hole 5 being used to insert a pressure measuring probe.
[0022] This utility model provides a renal pelvis endoscope tip design that optimizes and improves the front-end plate structure used for operation based on the traditional design. It adopts a bent, two-part plate structure instead of the usual flat plate design. The plate portion perpendicular to the central axis of the end-end housing 1 is used to house the lens hole 3, aligning the lens with a direction parallel to the end-end housing 1. The mechanical hole 4, for the surgical mechanism to pass through, is located on an inclined plate 2-2 with a certain angle. Thus, during surgery, when the mechanical mechanism passes through the mechanical hole 4, the inclination of the plate and the mechanical hole 4 keeps the mechanical mechanism away from the lens, effectively preventing the mechanical mechanism from impacting the lens. The obstruction of the lens ensures complete and effective imaging. A pressure measuring hole 5 for inserting a pressure measuring probe is provided on the outer peripheral wall of the end housing 1. This allows the pressure measuring probe to be directly integrated into the end position of the endoscope, and the pressure data at the end position can be fed back in real time. There is no need to use the mechanical hole 4 for pressure measurement. That is, when needed, the mechanical structure can be removed and replaced with the pressure measuring probe, which effectively simplifies the surgical procedure and avoids the possibility of cross-infection caused by pressure measurement. This effectively solves the technical problems of existing renal pelvic endoscope designs, which are easily affected by surgical observation and have cumbersome operation and infection risk.
[0023] In this embodiment, the angle between the inclined plate 2-2 and the axis of the end housing 1 is 40°-50°. This design further optimizes the design of the inclined plate 2-2 by limiting the angle between the inclined plate 2-2 and the axis of the end housing 1. When the angle is between 40°-50° or about 45°, the mechanical structure can maximize its avoidance of the camera's field of view.
[0024] In this embodiment, the angle between the axis of the mechanical hole 4 and the axis of the lens hole 3 is 15°-30°. This design optimizes the angle of the mechanical hole 4. Based on the tilt angle structure of the inclined plate 2-2, the tilt angle of the mechanical hole 4 is specifically optimized, with the hole direction at 15°-30° to the direction of the lens. This effectively avoids obstructing the camera's field of view and optimizes the insertion effect of the mechanical mechanism, ensuring that the mechanical structure can smoothly pass through the mechanical hole 4.
[0025] In this embodiment, the outer peripheral wall of the end cap 1 has two pressure measuring holes 5 on the side near the end plate 2. The two pressure measuring holes 5 are distributed 180° apart on the outer peripheral wall of the end cap 1, and a pressure measuring probe is inserted into each pressure measuring hole 5. This design further optimizes the design of the pressure measuring holes 5. The structure of two pressure measuring holes 5 with opposite orientation can eliminate possible positional errors when the endoscope tip is inserted. In addition, it should be noted that the end of the pressure measuring probe extends about 0.2 mm outside the pressure measuring hole 5, and the pressure sampling frequency is greater than 200 Hz.
[0026] In this embodiment, the outer peripheral wall of the end cap 1 has a stepped surface structure 6 at one end near the end plate 2. The stepped surface structure 6 is used for insertion with the endoscope tube. The pressure measuring holes 5 are all located at the radially larger end of the outer peripheral wall on one side of the stepped surface structure 6. This design optimizes the position of the pressure measuring holes 5 on the outer wall of the end cap 1. The stepped surface structure 6 facilitates insertion and positioning with the endoscope tube, and the placement of the pressure measuring holes 5 at the radially larger end of the outer peripheral wall on one side of the stepped surface structure 6 ensures that the pressure measuring probe protrudes to the outermost side of the end cap, thus ensuring the effectiveness of pressure measurement.
[0027] In this embodiment, the lens hole 3 is square-shaped, and the inner wall of the end housing 1 is provided with a stepped limiting structure 7 that communicates with the side wall of the lens hole 3. This design optimizes the structure of the lens hole 3 by using a square hole and providing a stepped surface structure 6 on the inner wall of the hole, which facilitates the formation of concave and convex positioning with the outer contour of the lens.
[0028] In this embodiment, the transition between the vertical plate 2-1 and the inclined plate 2-2 has a rounded edge structure. This design is suitable for the overall structure of the two-part end plate 2. The transition between the vertical and inclined plates has rounded edges instead of sharp corners, thus preventing the transition of the end plate 2 from harming the patient during surgery.
[0029] This utility model also provides an electronic pyeloscope, including an endoscope handle assembly and an endoscope tube, with an endoscope tip connected to the end of the endoscope tube. The endoscope tip is a multi-purpose tip for an electronic pyeloscope as described above. Since the multi-purpose tip for an electronic pyeloscope has the aforementioned beneficial effects, an electronic pyeloscope having this multi-purpose tip should also possess corresponding beneficial effects.
[0030] Although the embodiments of this utility model have been disclosed above, the scope of protection of this utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this utility model, and all such changes and modifications will fall within the protection scope of this utility model.
