Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary device for urological endoscopy, belonging to the field of medical device technology. Background Technology
[0002] During urological laparoscopic surgery, an auxiliary cannula is needed to provide a passageway for the endoscope, assisting medical personnel in inserting and positioning it. In this surgical environment, the instrument surfaces are often coated with bodily fluids or medical irrigation solutions, posing specific engineering requirements for the clamping stability and water-resistant properties of the operating aids.
[0003] Conventional urological endoscopy instruments typically employ a basic rigid straight tube structure as the guide channel. Because the outer surface of the endoscope is a smooth cylinder, the rigid straight tube only provides radial support and lacks a physical locking and restraining mechanism for the outer wall of the endoscope. During surgery, when encountering tissue resistance or adjusting insertion / extraction depth, the endoscope is prone to unexpected axial sliding and circumferential deflection within the cannula. The operator must rely on continuous finger pressure to maintain the relative position of the endoscope, increasing hand muscle fatigue and interfering with precise posture adjustments. Furthermore, there is an assembly gap between the inner wall of the existing rigid straight tube and the outer wall of the endoscope, and this gap lacks a physical blocking structure. Due to the pressure difference within the body cavity, body fluids and irrigation fluids often seep backward along this gap towards the posterior operating end. This overflowing fluid adheres to the instrument grip area, reducing surface friction and exacerbating the overall slippage phenomenon, thus affecting the physical stability of the entire surgical procedure.
[0004] Therefore, there is an urgent need in the field for an operating aid that can stably hold the endoscope during urological laparoscopic surgery to overcome the shortcomings of the existing technology. Utility Model Content
[0005] The purpose of this invention is to provide an auxiliary device for urological endoscopy, which avoids unexpected slippage of the endoscope, cuts off the physical path of reverse permeation of body fluids, and ensures a stable grip during clinical auxiliary operations.
[0006] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution:
[0007] A urological endoscope operating aid includes an operating handle and a connecting seat fixedly connected to one end of the operating handle. The operating handle serves as a support component for the operator's hand, and an anti-slip sleeve is fitted to the end opposite to the connecting seat. An auxiliary tube is detachably connected to the side of the connecting seat opposite to the operating handle. The auxiliary tube has a central channel extending through both ends to provide a supporting and protective shell for the insertion of the urological endoscope. A guide tube is connected inside the connecting seat to provide a guiding path for the endoscope to be inserted in a fixed direction. The end of the guide tube away from the connecting seat passes through the central channel and extends to the outer side of the end of the auxiliary tube away from the connecting seat. A sealing ring is provided between the guide tube and the auxiliary tube. A limiting clamping mechanism is also provided at the end of the auxiliary tube opposite to the connecting seat to clamp and fix the endoscope in the auxiliary tube after it reaches a predetermined operating depth.
[0008] Preferably, the auxiliary sleeve is a cylinder and is detachably connected to the connecting seat by a plurality of circumferentially distributed fixing bolts.
[0009] Preferably, the guide tube and the auxiliary sleeve are inserted with a clearance fit, and the sealing ring is fixedly connected to the inner wall of the auxiliary sleeve at the end facing the connecting seat, with the inner wall of the sealing ring slidingly fitting against the outer wall of the guide tube.
[0010] Preferably, the limiting clamping mechanism includes a limiting ring, an adjusting screw, and a limiting block. The limiting ring is sleeved on the outside of the auxiliary sleeve as the external bearing base of the limiting clamping mechanism. The adjusting screw is threaded through and screwed onto the side wall of the limiting ring. One end of the adjusting screw, which extends into the limiting ring, is screwed onto the limiting block. The rotation of the adjusting screw drives the limiting block to move radially along the auxiliary sleeve.
[0011] Furthermore, the limiting clamping mechanism also includes at least one positioning pin, which is fixedly connected to the side of the limiting block that is screwed to the adjusting screw. The end of the positioning pin away from the limiting block slides through the limiting ring, and the axial direction of the positioning pin is parallel to the axial direction of the adjusting screw.
[0012] Furthermore, the limiting clamping mechanism also includes an elastic pressure plate and a buffer pad. The elastic pressure plate is disposed on the side of the limiting block away from the adjusting screw, and the buffer pad is adhered to the side of the elastic pressure plate away from the limiting block.
[0013] Furthermore, the buffer pad is a rubber pad and has an inwardly concave arc shape on the side opposite to the elastic pressure plate.
[0014] Furthermore, the adjusting screw has an end cap at one end outside the limiting ring, and a spring is sleeved on the outer side of the adjusting screw between the end cap and the outer wall of the limiting ring.
[0015] Preferably, the outer surface of the anti-slip sleeve is provided with anti-slip ridges.
[0016] The urological endoscopy auxiliary device provided by this utility model has the following advantages: This utility model discloses a urological endoscope operating aid, wherein an auxiliary sleeve is connected to the end of the connecting seat, a guide tube is inserted inside the auxiliary sleeve, and a sealing ring is embedded in the inner wall of the auxiliary sleeve to fit the guide tube. A limiting ring is fitted to the outside of the auxiliary sleeve, and an adjusting screw is threaded to the side wall of the limiting ring. A limiting block is connected to the inner end of the adjusting screw, and an elastic pressure plate and a buffer pad are fixed inside the limiting block. A spring is fitted to the outside of the adjusting screw. The elastic pressure plate is moved by the thread, causing the buffer pad to abut against the endoscope body to generate resistance. The spring pushes the screw to prevent unintended slippage of the endoscope body. The sealing ring fills the assembly gap, cutting off the physical path of backflow of body fluid. The surface anti-slip sleeve uses convex textures to increase contact resistance, ensuring a stable grip during clinical auxiliary operations. Attached Figure Description

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Reference Figure 1 and Figure 2 A urological endoscopy operating aid includes an operating handle 1 and a connecting seat 3 fixedly connected to one end of the operating handle 1. The fixing method includes, but is not limited to, integral molding or bolt connection. The operating handle 1 serves as a support component for the operator's hand, and an anti-slip sleeve 2 is fitted to the end facing away from the connecting seat 3 to increase the friction between the operator's hand and the outer surface of the operating handle 1. The outer surface of the anti-slip sleeve 2 may also be provided with anti-slip textures to increase the surface roughness of the outer surface of the operating handle 1. When the operator's hand grips the operating handle 1 in an environment with body fluids, the anti-slip textures provide direct physical frictional resistance. The connecting seat 3 serves as a mounting base for the integral structure. The operating handle 1 is preferably cylindrical for easy gripping.
[0021] The auxiliary sleeve 4 is detachably connected to the side of the connecting seat 3 away from the operating handle 1. In feasible embodiments, the auxiliary sleeve 4 can be any shape of sleeve. In this embodiment, the auxiliary sleeve 4 is a cylinder and is detachably connected to the connecting seat 3 by a plurality of fixing bolts 5 that pass through the end of the auxiliary sleeve 4 and are distributed circumferentially. The fixing bolts 5 provide radial and axial locking and fixing support for the end of the auxiliary sleeve 4. The auxiliary sleeve 4 has a central channel that runs through both ends to provide a support and protective shell for the insertion of the urinary endoscope.
[0022] Reference Figures 1-4 A guide tube 7 is integrally formed or interference-fitted into the connecting seat 3 to facilitate quick assembly and disassembly of the auxiliary sleeve 4 and the connecting seat 3. The end of the guide tube 7 away from the connecting seat 3 has a central channel and extends to the outer side of the end of the auxiliary sleeve 4 away from the connecting seat 3, providing a guiding path for the endoscope body to be inserted in a fixed direction. The guide tube 7 and the auxiliary sleeve 4 are interlocked with a clearance fit. A sealing ring 6 is embedded and fixed on the inner wall of the end of the auxiliary sleeve 4 facing the connecting seat 3. The inner wall of the sealing ring 6 slides against the outer wall of the guide tube 7, filling the gap between the inside of the auxiliary sleeve 4 and the outside of the guide tube 7 to block the leakage path of body fluid or irrigation fluid. In this embodiment, the guide tube 7 and the connecting seat 3 are preferably interlocked with an interference fit.
[0023] Reference Figures 1-6The auxiliary sleeve 4 is also equipped with a limit clamping mechanism at the end opposite to the connecting seat 3 to clamp and fix the endoscope body in the auxiliary sleeve 4 after the endoscope body reaches the predetermined operating depth, so as to solve the problem of the endoscope body sliding and detaching during operation.
[0024] Specifically, the limiting clamping mechanism includes a limiting ring 8, an adjusting screw 12, and a limiting block 10. The limiting ring 8 is sleeved and fixed on the outside of the auxiliary sleeve 4 as the external bearing base of the limiting clamping mechanism. An adjusting screw 12 is threaded through and screwed onto the side wall of the limiting ring 8. One end of the adjusting screw 12 that extends into the limiting ring 8 is screwed onto the limiting block 10. The rotation of the adjusting screw 12 drives the limiting block 10 to move radially along the auxiliary sleeve 4.
[0025] In a further embodiment, the limiting clamping mechanism further includes at least one positioning pin 9, which is fixedly connected to the side of the limiting block 10 that is screwed to the adjusting screw 12. The end of the positioning pin 9 facing away from the limiting block 10 slides through the limiting ring 8. The axial direction of the positioning pin 9 is parallel to the axial direction of the adjusting screw 12. The positioning pin 9 provides a linear sliding guide for the radial movement of the limiting block 10 and restricts the limiting block 10 from rotating and deflecting with the adjusting screw 12.
[0026] In a further embodiment, the limiting clamping mechanism also includes an elastic pressure plate 11 and a buffer pad 14. The elastic pressure plate 11 is fixedly connected to the side of the limiting block 10 away from the adjusting screw 12. The buffer pad 14 is bonded to the side of the elastic pressure plate 11 away from the limiting block 10. The buffer pad 14 is a rubber pad and the side away from the elastic pressure plate 11 is concave arc-shaped. This concave surface structure is adapted to the cylindrical outer contour size of the urinary endoscope. The elastic pressure plate 11 uses its own deformation to provide a flexible transition for radial advancement. The buffer pad 14 directly presses against the outer surface of the endoscope to provide frictional resistance.
[0027] Reference Figure 6 In a further embodiment, the adjusting screw 12 has an end cap at one end outside the limiting ring 8. A spring 13 is sleeved on the outer side of the adjusting screw 12 between the end cap and the outer wall of the limiting ring 8. One end of the spring 13 abuts against the bottom wall of the end cap, and the other end abuts against the outer surface of the limiting ring 8. The spring 13 is in a compressed state when the adjusting screw 12 is pushed inward and pressed. The spring 13 provides a continuous outward axial support thrust to the adjusting screw 12. This thrust increases the friction between the threaded mating surface of the adjusting screw 12 and the limiting ring 8, preventing the adjusting screw 12 from loosening and unthreading after clamping the endoscope body.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit this utility model in any form or substance. It should be noted that those skilled in the art can make various improvements and additions without departing from this utility model, and these improvements and additions should also be considered within the protection scope of this utility model. Any modifications, alterations, and equivalent changes made by those skilled in the art without departing from the spirit and scope of this utility model using the disclosed technical content are equivalent embodiments of this utility model. Furthermore, any modifications, alterations, and evolutions made to the above embodiments based on the essential technology of this utility model are still within the scope of the technical solution of this utility model.
