Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a multi-angle rotating adaptable laparoscopic surgical tubing support tool. Background Technology

[0002] As a core component of laparoscopic clinical surgery, the light source cable, with its built-in fiber optic elements, provides cold light illumination for the procedure and is crucial for ensuring precise digital imaging within the laparoscopic lens. Its unique characteristic—connecting the instrument at one end and the laparoscope at the other—makes the junction of the rigid and flexible parts at the cable's end a vulnerable point, prone to bending and damage due to a lack of effective support. Since a single light source cable can cost tens or even hundreds of thousands of yuan, frequent repairs or replacements would impose a significant financial burden.

[0003] In clinical practice, to avoid frequent bending of the light source wire, medical staff usually use a protective method of adjusting the bending radius and holding it together with the handle. This aims to maintain a suitable bending radius and prevent shaking during surgery. However, the operation time is often long, and the light source wire is prone to shifting from the hand, causing bending damage again, which is difficult to fundamentally solve the problem.

[0004] A search revealed that existing technologies, such as the Chinese utility model patent with authorization announcement number CN 210842974 U and the Chinese patent application with application publication number CN 112987280 A, propose using Velcro straps or telescopic adjustable support rods for tubing positioning. However, these methods suffer from insufficient rotational freedom, limited adaptability, and inconvenient assembly and disassembly. Especially when the endoscope rotates, existing tools, due to their limited functionality, cannot meet the multi-angle rotation adjustment needs of the light source line, thus hindering the convenience of surgical procedures.

[0005] Therefore, it is necessary to develop a support tool that can rotate in multiple directions and is widely adaptable to solve the industry pain points of light source line bending damage and lack of versatility. Utility Model Content

[0006] To address the problems existing in the background art, this utility model proposes a multi-angle rotational adaptable laparoscopic surgical tubing support tool. This utility model effectively solves the problems of easy damage to the laparoscopic surgical light source line and poor adaptability of the support tool in the prior art. Through the multi-angle rotational adaptability of the universal metal tube, combined with the flexible locking and sliding constraint of the tube clamp, it can effectively maintain a suitable bending radius of the light source line, avoiding bending damage at the soft-hard joint. It also features convenient assembly and disassembly, and a wide range of adaptability, thereby improving the convenience of laparoscopic surgical operations and reducing the maintenance and replacement costs of the light source line.

[0007] The technical solution to the technical problem solved by this utility model is as follows:

[0008] A multi-angle rotating adaptable laparoscopic surgical tubing support tool includes a bendable universal metal tube, which has a straight state and a curved state, and can freely change and adjust between the straight state and the curved state according to the position of the light source line; one end of the universal metal tube is connected to a fastener, which can be detachably connected to a rigid connector on the endoscope; at least one first tube clamp is detachably snapped onto the body of the universal metal tube, and a second tube clamp is connected to one side of the first tube clamp. The second tube clamp can be snapped onto the light source line of the endoscope, and the light source line can slide relative to the second tube clamp.

[0009] Preferably, the universal metal pipe is a stainless steel shower pipe.

[0010] Preferably, the first pipe clamp and the second pipe clamp are connected in a detachable manner.

[0011] Preferably, the first pipe clamp has a threaded hole on its side wall, and the second pipe clamp has a threaded post fixedly connected to its side wall, the threaded post being adapted to the threaded hole.

[0012] Preferably, the fastener includes an end plate, which is fixedly connected to the top end of the universal metal tube, and a third pipe clamp is fixedly connected to one side of the end plate, which can be clamped onto the rigid connector.

[0013] Preferably, the first pipe clamp, the second pipe clamp, and the third pipe clamp are made of plastic or stainless steel.

[0014] Preferably, the length of the universal metal tube is 10-20cm.

[0015] Preferably, there are no fewer than two first pipe clamps, which are spaced apart along the length of the universal metal pipe.

[0016] Preferably, the fastener uses two mating saddle clips, which are fixed together by bolts to clamp the rigid joint; one of the saddle clips is fixed to the top of the universal metal tube.

[0017] Preferably, the first pipe clamp has a clamping platform at one end and the second pipe clamp has a clamping slot at one end, and the clamping platform and the clamping slot can be fitted together.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] 1. This utility model, through the setting of a universal metal tube, a first tube clamp, and a second tube clamp, allows the universal metal tube to freely switch between straight and curved states as the position of the light source line changes, maintaining a suitable bending radius for the light source line at all times and avoiding damage to the fiber optic components due to excessive bending. In addition, the second tube clamp holds the light source line in place while allowing it to slide relative to the light source line, fixing the position of the line without restricting its necessary displacement. This ensures the relative adjustment of the position between the universal metal tube and the light source line, effectively reducing the frequency of maintenance and replacement of the light source line and lowering costs.

[0020] 2. To address the issue of insufficient rotational freedom in existing tools, this tool utilizes the multi-angle bending characteristics of a universal metal tube to synchronously adjust its shape to follow rotation and movement during laparoscopic surgery. This ensures that the light source line is always in a properly supported state and will not lose support due to changes in the surgical angle, significantly improving the convenience of surgical operations and reducing interference with surgical precision caused by tubing entanglement.

[0021] 3. The fasteners and rigid connectors of the endoscope are detachably connected, and the first and second tube clamps are detachably combined. The detachable connection method allows for flexible adjustment according to the rigid connector specifications and light source wire size of different endoscope models, solving the problem of limited compatibility of existing tools.

[0022] 4. This device has a simple structure, is easy to manufacture, and is convenient to operate. It can be quickly installed or disassembled without complicated tools, which meets the needs of rapid adjustment during surgery, reduces the time cost of preoperative preparation and postoperative cleanup, and improves the efficiency of clinical operation.

[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0039] like Figure 1 As shown, Figure 1This is a schematic diagram of the structure of a conventional endoscope. The conventional endoscope includes an endoscope body 1, which is mainly composed of three parts: a handle 101, a endoscope body 102 connected to the handle 101 (the endoscope body 102 and handle 101 are detachably connected), and the endoscope body 102 can rotate relative to the handle 101. A sheath 103 is fitted onto the endoscope body 102, also detachably connected, and the sheath 103 can rotate relative to the endoscope body 102. A light source connector 1021 is provided on the endoscope body 102, and a light source line 2 can be detachably connected to the light source connector 1021. The light source line 2 includes a flexible conduit 22, and the end of the flexible conduit 22 is provided with a rigid connector 21 that can be fitted and inserted into the light source connector 1021. The connection between the flexible conduit 22 and the rigid connector 21 is the soft-hard joint described in the background art, and this part is extremely prone to bending and damage.

[0040] like Figure 2 - Figure 8 As shown, in order to solve this technical problem, this embodiment proposes a multi-angle rotation adaptable laparoscopic surgical tubing support tool, which includes a bendable universal metal tube 3. The universal metal tube 3 has a straight state and a bent state, and the universal metal tube 3 can freely change and adjust between the straight state and the bent state as the position of the light source line 2 changes. The advantage of this design is that the universal metal tube 3 can freely switch between the straight state and the bent state as the position of the light source line 2 changes, and can always maintain a suitable bending radius of the light source line 2, avoiding damage to the fiber optic components due to excessive bending.

[0041] One end of the universal metal tube 3 is connected to a fastener 6, which can be detachably connected to the rigid connector 21 on the endoscope; at least one first tube clip 4 is detachably snapped onto the tube body of the universal metal tube 3, and a second tube clip 5 is connected to one side of the first tube clip 4. The second tube clip 5 can be snapped onto the light source line 2 of the endoscope, and the light source line 2 can slide relative to the second tube clip 5.

[0042] The second pipe clamp 5 clamps the light source line 2 and allows it to slide relative to the light source line 2. This fixes the position of the line without restricting its necessary displacement, thus reducing local stress damage caused by hard constraints.

[0043] In some embodiments, the universal metal pipe 3 may be a stainless steel shower pipe, a titanium alloy flexible metal pipe, a shapeable metal snake pipe, etc.

[0044] The universal metal tube 3 has a preset maximum bending curvature. When bent to this maximum curvature, it cannot be bent further, thus forming a mechanical limit on excessive bending of itself and the light source line 2. The preset maximum bending curvature can strictly control the degree of bending of the light source line 2 through mechanical limiting, keeping it within a safe bending radius. This fundamentally avoids damage to the fiber optic components caused by improper operation (such as excessive bending due to surgical errors), protects the core function of the light source line 2, and reduces high maintenance or replacement costs. During surgery, the position of the light source line 2 needs to be frequently adjusted with the endoscope. Mechanical limiting provides medical staff with clear operating boundaries, preventing sudden excessive bending of the light source line 2 due to excessive angle adjustment. This maintains the stable illumination and signal transmission function of the light source line 2, reduces interference with the surgical field of view and precise operation, and improves surgical safety.

[0045] In this embodiment, a stainless steel shower hose is preferred. It is typically composed of multiple connected movable metal segments, giving it excellent natural flexibility and shape retention. It can be freely bent into any angle (straight or curved) and stably maintain its intended shape, ensuring consistent support for the light source line 2 during surgery, maintaining a suitable bending radius, and preventing damage to the soft-hard joint due to excessive bending. It possesses moderate structural strength, stably supporting the weight of the light source line 2 without limiting flexible adjustments during surgical operations due to excessive rigidity, thus balancing support stability and operational flexibility.

[0046] Furthermore, stainless steel shower hoses are mature, mass-produced, and standardized components in industry, with wide procurement channels and controllable costs. There's no need to design complex processing techniques separately for the universal metal hose 3, reducing the overall manufacturing cost of the tool and facilitating large-scale production and clinical application. Stainless steel itself possesses excellent corrosion resistance and rust resistance, and can withstand high-temperature sterilization and frequent treatment with chemical disinfectants, meeting the stringent sterile environment requirements of operating rooms.

[0047] In summary: By incorporating the universal metal tube 3, the first clamp 4, and the second clamp 5, the universal metal tube 3 can freely switch between straight and curved states as the position of the light source line 2 changes, maintaining a suitable bending radius for the light source line 2 and preventing damage to the fiber optic components due to excessive bending. Furthermore, the second clamp 5 secures the light source line 2 while allowing it to slide relative to it, fixing the line position without restricting necessary displacement. This ensures relative adjustment between the universal metal tube 3 and the light source line 2, effectively reducing the frequency of maintenance and replacement of the light source line 2 and lowering costs.

[0048] To address the issue of insufficient rotational freedom in existing tools, this tool utilizes the multi-angle bending characteristics of the universal metal tube 3 to synchronously adjust its shape to follow rotation and movement during laparoscopic surgery. This ensures that the light source line 2 is always in a properly supported state and will not lose support due to changes in the surgical angle, significantly improving the convenience of surgical operations and reducing interference with surgical precision caused by tubing entanglement.

[0049] In some embodiments, the first pipe clamp 4 and the second pipe clamp 5 can be connected by fixed welding, bonding, or a detachable connection. As a feasible embodiment, the side wall of the first pipe clamp 4 has a threaded hole 8, and the side wall of the second pipe clamp 5 is fixedly connected with a threaded post 7, which is adapted to the threaded hole 8.

[0050] As one possible implementation, such as Figures 10-12 As shown, the first pipe clamp 4 and the second pipe clamp 5 can also be connected by a detachable plug-in method. One end of the first pipe clamp 4 has a clamping platform 41, and one end of the second pipe clamp 5 has a clamping groove 51. The clamping platform 41 and the clamping groove 51 can be fitted together. In this embodiment, the structure of the clamping platform 41 and the cross-sectional shape of the clamping groove 51 are "T" shaped. If necessary, a thickened layer 511 can be provided on the outer wall of the clamping groove 51 to facilitate a tight connection between the first pipe clamp 4 and the second pipe clamp 5.

[0051] The first tube clamp 4 and the second tube clamp 5 can be detachably combined by threaded connection or plug-in connection, and can be flexibly adjusted according to the specifications of rigid connector 21 and the size of light source line 2 of different models of endoscopes, which solves the problem of limited compatibility of existing tools.

[0052] In some embodiments, the fastener 6 can be a combination of the first tube clamp 4 and the second tube clamp 5; in some embodiments, the fastener 6 can also have the following structure: the fastener 6 includes an end plate 61, which is fixedly connected to the top end of the universal metal tube 3, and a third tube clamp 62 is fixedly connected to one side of the end plate 61, which can be snapped onto the rigid connector 21. The snap-fit ​​method has the characteristic of "install and remove immediately," allowing for quick installation or removal without additional tools. This meets the clinical needs of quickly adjusting tool positions during surgery, reducing the time cost of preoperative preparation and postoperative cleanup, and improving operational efficiency.

[0053] The first clamp 4, the second clamp 5, and the third clamp 62 mentioned above are made of plastic or stainless steel. In this embodiment, stainless steel is preferred because it is resistant to disinfection and corrosion, can withstand the high-temperature or chemical disinfection treatments in the operating room, is not easily aged or damaged due to disinfection, extends the service life of the tool, and meets the usage standards of a medical sterile environment.

[0054] In some embodiments, the length of the universal metal tube 3 is 10 to 20 cm. The length of 10 to 20 cm can cover the key support section (especially the vulnerable soft and hard joint) of the light source line 2 extending from the rigid connector 21, without taking up too much space due to excessive length, thus avoiding interference with surgical instruments, doctor's hand operations or patient's body, and ensuring the smoothness of surgical operation.

[0055] In some embodiments, the number of first tube clamps 4 is not less than two, and they are spaced apart along the length of the universal metal tube 3. This provides stable support for different sections of the light source line 2 and adapts to the needs of light source lines 2 of different lengths and shapes.

[0056] In some embodiments, fastener 6 may also take the following structural form:

[0057] like Figure 9 As shown, fastener 6 uses two mating saddle clips 9, which are fixed together by bolts to clamp the rigid connector 21; one of the saddle clips 9 is fixed to the top of the universal metal tube 3. The saddle clips 9 are made of stainless steel or aluminum alloy. The two mating saddle clips 9, fixed by bolts, form a ring-shaped clamping structure, ensuring a firm connection between the universal metal tube 3 and the rigid connector 21. This prevents the light source line 2 from losing support due to tool shaking or falling off during surgery, thus ensuring the stability of the overall support structure from the connection end. In addition, the clamping distance between the two saddle clips 9 can be flexibly adjusted by tightening and loosening the bolts, which can accommodate rigid connectors 21 of different diameters and models of laparoscopy, solving the problem of limited compatibility in existing technologies and improving the versatility of the tool.

[0058] The installation method for this tool is described below:

[0059] S1. Prepare the following components: universal metal tube 3 (length 10-20cm), fastener 6, at least 2 first tube clamps 4, and second tube clamps 5 that match the first tube clamps 4; ensure that the rigid connector 21 of the endoscope and the light source line 2 are in the ready-to-install state.

[0060] S2. Assemble the first pipe clamp 4 and the second pipe clamp 5:

[0061] Align the threaded post 7 on the side wall of the second pipe clamp 5 with the threaded hole 8 on the side wall of the first pipe clamp 4, and rotate and tighten to secure the connection between the two. Repeat this operation to complete the assembly of all first pipe clamps 4 and second pipe clamps 5.

[0062] S3. Install the assembled pipe clamps onto the universal metal pipe 3:

[0063] The assembled pipe clamps are attached to the pipe body at intervals along the length of the universal metal pipe 3, and the spacing between each assembly is adjusted so that it can cover the key section (especially the soft and hard joint) of the light source line 2 extending from the rigid connector 21.

[0064] S4, Fixing fastener 6 and rigid connector 21 of the endoscope:

[0065] Connect fastener 6 to the rigid connector 21 of the endoscope, ensuring it is secure and does not loosen.

[0066] S5, Fix the light source line 2 to the second tube clamp 5:

[0067] Insert the light source line 2 of the endoscope into each of the second tube clamps 5 in sequence, ensuring that the second tube clamps 5 do not compress the tubes; adjust the position of the light source line 2 so that the light source line 2 can slide freely relative to the second tube clamps 5.

[0068] S6. Check installation stability:

[0069] Gently shake the endoscope and light source line 2 to confirm that the fastener 6 and rigid connector 21 are firmly connected, the pipe clamp assembly does not detach from the universal metal tube 3, the second pipe clamp 5 provides stable constraint on the light source line 2 and does not affect its sliding, and the universal metal tube 3 can freely adjust its shape as the position of the light source line 2 changes. The overall installation is complete.

[0070] In summary, this device has a simple structure, is easy to manufacture, and is convenient to operate. It can be quickly installed or disassembled without complicated tools, making it suitable for the need for rapid adjustments during surgery. This reduces the time cost of preoperative preparation and postoperative cleanup, and improves the efficiency of clinical operations.
