Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a multifunctional ureteroscope sheath fixation device. Background Technology

[0002] Flexible ureteroscopy is a commonly used minimally invasive surgical procedure in urology. During the procedure, a flexible ureteroscope sheath is inserted into the patient's body to establish an operating channel.

[0003] However, in existing technologies, flexible endoscope sheaths are prone to displacement or dislodgement during surgery. Due to surgical procedures or changes in patient positioning, the flexible endoscope sheath is easily displaced, affecting the surgical field of vision and operation. Currently, there is a lack of dedicated fixation devices, and surgeons usually rely on manual fixation or the use of simple auxiliary tools, which is not ideal and increases the difficulty and risk of the surgery.

[0004] Therefore, there is an urgent need for a device that can effectively fix the flexible endoscope sheath to improve the safety and efficiency of surgery and solve the problems of easy displacement and inconvenience in fixing the flexible endoscope sheath. Utility Model Content

[0005] In view of this, this utility model proposes a multifunctional ureteroscope sheath fixation device, which aims to solve the problems of easy displacement and inconvenience in fixing the flexible ureteroscope sheath.

[0006] This utility model provides a multifunctional ureteroscope sheath fixation device, comprising:

[0007] Base plate;

[0008] Connecting arms are fixed to both sides of the base plate, and the connecting arms are used to fix the base plate.

[0009] A support ring is provided on the upper side of the base plate, and the upper part of the support ring is open;

[0010] A fixing clamp assembly is disposed on the upper part of the base plate, wherein the fixing clamp assembly includes a main fixing clamp and a secondary fixing clamp;

[0011] The main fixing clamp is disposed on the upper part of the base plate, and a first hinge assembly is provided on one side of the main fixing clamp so that the side of the main fixing clamp opposite to the first hinge assembly can be opened and closed.

[0012] The secondary fixing clip is disposed on the upper part of the base plate, and a second hinge assembly is provided on one side of the secondary fixing clip so that the side of the secondary fixing clip opposite to the second hinge assembly can be opened and closed.

[0013] Furthermore, the fixing clamp assembly is provided with reinforcing blocks, and a plurality of reinforcing blocks are provided, which are disposed on the inner walls of the main fixing clamp and the secondary fixing clamp.

[0014] Furthermore, the reinforcing block includes:

[0015] The buffer section is fixed to the inner wall of the main fixing clamp or the secondary fixing clamp;

[0016] The block is fixed on the side of the buffer portion away from the main or secondary fixing clamp.

[0017] Furthermore, the buffer section includes:

[0018] Springs, rubber pads, silicone blocks, or airbag cushions.

[0019] Furthermore, the multifunctional ureteroscope sheath fixation device also includes:

[0020] A connector is disposed between the base plate and the fixing clamp assembly, and the connector is also disposed between the base plate and the supporting ring; wherein, the connector includes a telescopic rod and a rotating support;

[0021] One end of the telescopic rod is connected to the fixing clamp assembly or the supporting ring;

[0022] The rotating support is disposed on the upper part of the base plate, and the side of the rotating support away from the base plate is connected to the telescopic rod so that the telescopic rod is rotatably connected to the base plate.

[0023] Furthermore, the connecting arm includes:

[0024] A connecting strap, one end of which is connected to the base plate;

[0025] A fixing piece is connected to the end of the connecting strip away from the base plate;

[0028] Furthermore, the connecting belt is a telescopic belt.

[0029] Furthermore, the inner diameter of the main fixing clamp is larger than the inner diameter of the secondary fixing clamp.

[0030] Compared with existing technologies, the advantages of this invention are that it improves the stability and convenience of surgical procedures. Firstly, the use of a split-type fixation clamp assembly (main and secondary clamps) allows for unilateral opening and closing via a first and second hinge assembly, enabling surgeons to quickly fix and load / unload flexible endoscope sheaths of different sizes with one hand, solving the problem of inability to fix the sheath during surgery in existing technologies. Secondly, the integrated design of the base plate and connecting arm forms a stable support structure through double-sided fixation, firmly conforming to the patient's skin or sterile drapes, effectively preventing sheath displacement due to changes in body position during surgery. Furthermore, the upper opening design of the support ring allows for flexible placement of the catheter and prevents it from falling out, avoiding additional fixation steps. The differentiated configuration of the main and secondary clamps can simultaneously meet the fixation needs of sheaths of different diameters, enhancing clinical adaptability. The hinged opening and closing structure significantly shortens instrument preparation time. The overall device optimizes space utilization through a modular layout, reducing interference from instrument stacking during surgery while ensuring functional completeness.

[0040] See Figure 1-3 As shown, this embodiment provides a multifunctional ureteroscope sheath fixation device, including a base plate 100;

[0041] Connecting arms 200 are fixed on both sides of the base plate 100, and the connecting arms 200 are used to fix the base plate 100.

[0042] A support ring 300 is disposed on the upper side of the base plate 100, and the upper part of the support ring 300 is open;

[0043] A fixing clamp assembly 400 is disposed on the upper part of the base plate 100, wherein the fixing clamp assembly 400 includes a main fixing clamp 410 and a secondary fixing clamp 420.

[0044] The main fixing clamp 410 is disposed on the upper part of the base plate 100, and a first hinge assembly is provided on one side of the main fixing clamp 410 so that the side of the main fixing clamp 410 opposite to the first hinge assembly can be opened and closed.

[0045] The secondary fixing clip 420 is disposed on the upper part of the base plate 100, and a second hinge assembly is provided on one side of the secondary fixing clip 420 so that the side of the secondary fixing clip 420 opposite to the second hinge assembly can be opened and closed.

[0046] Understandably, this invention improves the stability and convenience of surgical procedures. Firstly, the use of a split-type fixation clip assembly 400 (main fixation clip 410 and secondary fixation clip 420) allows for unilateral opening and closing via a first and second hinge component, enabling surgeons to quickly fix and attach / remove flexible endoscope sheaths of different sizes with one hand, solving the problem of inability to fix flexible endoscope sheaths during surgery in existing technologies. Secondly, the integrated design of the base plate 100 and connecting arm 200 forms a stable support structure through bilateral fixation, firmly conforming to the patient's body surface or sterile drapes, effectively preventing sheath displacement due to changes in body position during surgery. Furthermore, the upper opening design of the support ring 300 allows for flexible placement of the urinary catheter while preventing dislodgement, avoiding additional fixation steps. The differentiated configuration of the main / secondary fixation clips 420 can simultaneously meet the fixation needs of sheaths of different diameters, enhancing clinical adaptability. The hinged opening and closing structure significantly shortens instrument preparation time. The overall device optimizes space utilization through a modular layout, reducing interference from instrument stacking during surgery while ensuring functional completeness. Specifically, the first and second hinge components can be the hinge components of a clamp in the prior art.

[0047] In some embodiments of this application, the fixing clamp assembly 400 is provided with a reinforcing block 500, and a plurality of reinforcing blocks 500 are provided. The reinforcing blocks 500 are disposed on the inner walls of the main fixing clamp 410 and the secondary fixing clamp 420.

[0048] In some embodiments of this application, the reinforcing block 500 includes:

[0049] The buffer part 510 is fixed on the inner wall of the main fixing clamp 410 or the secondary fixing clamp 420;

[0050] The block 520 is fixed to the side of the buffer portion 510 away from the main fixing clamp 410 or the secondary fixing clamp 420.

[0051] Understandably, the fixation clamp assembly 400 is equipped with a reinforcing block 500 with a buffer structure. The reinforcing block 500 adopts a combination structure of a split buffer part 510 and a block 520. The buffer part 510 is fixed to the inner wall of the fixation clamp, and the block 520 is in direct contact with the sheath through an elastic connection. This ensures the stability of the clamping and effectively absorbs the vibration and impact during the surgical operation. The array arrangement of multiple reinforcing blocks 500 on the inner wall of the fixation clamp forms a uniform force point, avoiding sheath deformation caused by local stress concentration. The elastic characteristics of the buffer part 510 can automatically adjust the contact pressure according to different specifications of sheaths, ensuring a secure fixation while preventing excessive compression. Preferably, the surface of the block 520 is further designed with anti-slip textures, which significantly improves the coefficient of friction, prevents the sheath from sliding axially, makes the sheath fixation safer and more reliable, and reduces the risk of mechanical damage to the sheath and patient tissues during the surgical operation.

[0052] In some embodiments of this application, the buffer 510 includes:

[0053] Springs, rubber pads, silicone blocks, or airbag cushions.

[0054] Understandably, the buffer section 510 can employ various elastic structures such as springs, rubber pads, silicone blocks, or air cushions, each with unique technical advantages: spring buffers (especially micro-coil springs or wave springs) provide precise and controllable elastic clamping force; rubber pads offer excellent cushioning performance and wear resistance, maintaining their elastic properties over a long period; silicone blocks combine good biocompatibility and conformability, automatically adapting to the surface contours of sheaths of different diameters; and air cushions support dynamic pressure adjustment during surgery, achieving real-time control of clamping force through inflation and deflation. These buffer structures effectively absorb vibrations and impacts during surgical procedures, significantly reducing the risk of mechanical damage to the sheath while ensuring fixation reliability. In particular, their self-adaptive elasticity prevents sheath slippage due to excessively loose clamping, and avoids sheath deformation or patient tissue damage caused by excessively tight clamping, greatly improving surgical safety and ease of operation.

[0055] In some embodiments of this application, the multifunctional ureteroscope sheath fixation device further includes:

[0056] A connector 600 is disposed between the base plate 100 and the fixing clamp assembly 400, and the connector 600 is also disposed between the base plate 100 and the supporting ring 300; wherein, the connector 600 includes a telescopic rod 610 and a rotating support 620.

[0057] One end of the telescopic rod 610 is connected to the fixing clamp assembly 400 or the supporting ring 300;

[0058] The rotating support 620 is disposed on the upper part of the base plate 100, and the side of the rotating support 620 away from the base plate 100 is connected to the telescopic rod 610 so that the telescopic rod 610 is rotatably connected to the base plate 100.

[0059] Understandably, the length adjustment function of the telescopic rod 610 allows for precise control of the spatial position of the fixation clamp assembly 400 and the support ring 300, meeting the personalized needs of different surgical positions and anatomical structures. The rotating connection design of the rotating support 620 enables the fixation clamp assembly 400 or the support ring 300 to achieve 360° free angle adjustment, ensuring the optimal operating angle during surgery. The connector 600 dynamically connects the fixation clamp assembly 400, the support ring 300, and the base plate 100, maintaining the overall stability of the device while providing flexibility for independent adjustment of each functional module. Especially in complex surgeries, surgeons can quickly adjust the position of the sheath and drainage tube according to real-time needs without having to re-fix the entire device, significantly improving surgical efficiency. This adjustable connection structure allows the device to adapt to various surgical scenarios, from routine to special, significantly expanding its clinical applicability while reducing the risk of tissue damage caused by repeated adjustments.

[0060] In some embodiments of this application, the connecting arm 200 includes:

[0061] Connecting strap 210, one end of which is connected to the base plate 100;

[0062] The fixing piece 220 is connected to the end of the connecting strip 210 away from the base plate 100;

[0063] An adhesive tape 230 is disposed on the fixing piece 220, and the adhesive tape 230 is used to fix the base plate 100.

[0064] Understandably, the connecting strap 210 allows the device to adapt to the patient's body surface curves, ensuring fixation stability; the fixation plate 220 provides a flat attachment surface for the adhesive tape 230, enhancing adhesion; the design of the adhesive tape 230 enables quick installation and removal, ensuring secure fixation during surgery and easy removal after surgery, avoiding damage to the patient's skin.

[0065] In some embodiments of this application, the connecting strap 210 is provided with a D-ring buckle 211 to adjust the length of the connecting strap 210.

[0066] In some embodiments of this application, the connecting strap 210 is a telescopic strap.

[0067] Understandably, the use of either a D-ring 211 or a telescopic strap in the connecting strap 210 significantly improves the clinical applicability and ease of operation of the device. The D-ring 211 adjustment mechanism allows surgeons to quickly and precisely adjust the length of the connecting strap 210, ensuring a perfect fit between the fixation device and the patient's body surface; while the telescopic strap has self-adjusting characteristics, automatically adjusting tension according to changes in intraoperative positioning to maintain optimal fixation. This solves the problem of poor adaptability caused by the fixed length of traditional fixation devices, adapting to the anatomical characteristics of patients with different body types. In particular, the phased locking function of the D-ring 211 ensures both adjustment flexibility and fixation reliability; the elasticity of the telescopic strap buffers the traction force generated during surgical procedures, reducing the risk of device displacement.

[0068] In some embodiments of this application, the inner diameter of the main fixing clip 410 is larger than the inner diameter of the secondary fixing clip 420.

[0069] Understandably, the dual-size fixation clip design allows a single device to be adapted to different models of ureteroscope sheaths simultaneously, significantly expanding the device's applicability. Especially in complex surgeries, the dual-fixation clip structure allows for the simultaneous stabilization of multiple instruments, avoiding the hassle of frequently changing fixation devices during surgery and reducing surgical field interference caused by instrument stacking, thus greatly improving surgical efficiency and operational safety.

[0070] The working principle of this utility model is as follows: First, the adhesive tape 230 and connecting tape 210 of the connecting arm 200 are used to firmly fix the device to the patient's body surface; then, the different inner diameter design of the primary and secondary fixing clips 420 is used to clamp soft endoscope sheaths of different specifications respectively; the telescopic rod 610 and rotating support 620 in the connector 600 support real-time adjustment of the fixed position and angle during the operation; the open design of the support ring 300 enables flexible management of the drainage tube.

[0071] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
