Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a replaceable operating sheath for a cholangioscope. Background Technology

[0002] In biliary tract surgery, the cholangioscopy, with its direct visualization capabilities, has become an essential tool for procedures such as bile duct stone exploration, stone removal, and lesion observation. The operating sheath, as a key component of the cholangioscopy system, not only establishes the surgical pathway but also works with inlet tubing and mesh tubing to perform procedures such as irrigation and stone removal; its performance directly affects the success of the surgery. Traditional cholangioscopy operating sheaths have several limitations. Firstly, the connection structure between the operating sheath and the connector is complex. When different sizes of operating sheaths need to be quickly changed during surgery, specific tools are often required for disassembly, which is time-consuming and laborious. Especially in emergency surgical scenarios, prolonged disassembly can delay the operation and increase patient risk.

[0003] The inventors believe that the following defects often exist: when staff need to quickly separate the connector of the collector from the operating sheath body to facilitate the replacement of different operating sheath bodies, the connection between the operating sheath body and the connector is too rigid, requiring time and effort to find and disassemble the tools, which wastes surgical time and thus affects the progress of the operation and endangers the patient's health; therefore, in order to address the above problems, a replaceable operating sheath for cholangioscopy is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the connection between the operating sheath and the connector is too rigid, requiring time and effort to find and disassemble tools, thus wasting surgical time, affecting the progress of the surgery, and endangering the patient's health. Therefore, this invention proposes a replaceable operating sheath for cholangioscopy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a replaceable operating sheath for a cholangioscope, comprising an operating sheath body, a connector slidably mounted on one side of the operating sheath body, a mesh tube connected to the arc surface of the operating sheath body, a liquid inlet tube connected to the arc surface of the operating sheath body, a disassembly device provided on the arc surface of the operating sheath body, the disassembly device comprising an L-shaped plate, the L-shaped plate being fixedly connected to the arc surface of the operating sheath body, a connecting block slidably connected to the surface of the L-shaped plate, the connecting block being fixedly connected to the arc surface of the connector, a fixing rod fixedly connected to the surface of the connecting block, an operating plate slidably connected to the arc surface of the fixing rod, an insertion rod fixedly connected to one side of the operating plate, and an insertion hole provided on the surface of the L-shaped plate.

[0006] The aforementioned components achieve the following effect: by setting up a disassembly device, the operating sheath body and connector can be easily separated and disassembled quickly. This avoids the situation where the connection between the operating sheath body and the connector is too strong, requiring time and effort to find and disassemble tools when staff need to quickly separate the connector of the collector from the operating sheath body to facilitate the replacement of different operating sheath bodies. This would waste surgical time, affect the progress of the operation, and endanger the patient's health, thus improving the practicality of the device.

[0007] Preferably, a limiting plate is fixedly connected to the end of the fixing rod away from the connecting block, and the size of the insertion rod is adapted to the size of the L-shaped plate insertion hole.

[0008] The effect achieved by the above components is that the limiting plate restricts the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thus preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the operator pulls it.

[0009] Preferably, a first spring is fitted onto the arc surface of the fixing rod, and the two ends of the first spring are fixedly connected to the operating plate and the connecting block, respectively.

[0010] The effect achieved by the above components is that the first spring improves the stability of the insertion rod when it is positioned relative to the L-shaped plate.

[0011] Preferably, a rubber ring is fixedly connected to the surface of the operating panel, and the rubber ring is slidably connected to the arc surface of the fixing rod.

[0012] The effect achieved by the above components is that the elasticity of the rubber ring wraps around the fixed rod, thereby slowing down the sliding speed of the operating plate on the arc surface of the fixed rod, and reducing the impact of external shaking on the operating plate, thus achieving a damping effect.

[0013] Preferably, a positioning block is fixedly connected to the surface of the L-shaped plate, and the positioning block is slidably connected to one side of the connecting block.

[0014] The aforementioned components achieve the following effect: they position the L-shaped plate into the connecting block, allowing workers to quickly insert the rod into the L-shaped plate and improving their work efficiency.

[0015] Preferably, the arc surface of the mesh tube is provided with a protective device, the protective device including a support plate, the support plate being fixedly connected to the arc surface of the mesh tube, a rotating rod being fixedly connected to the upper surface of the support plate, a protective plate being rotatably connected to the end of the rotating rod away from the support plate, a square rod being slidably inserted into the protective plate, and two square holes being opened on the surface of the support plate.

[0016] The aforementioned components achieve the following effects: by setting up protective devices, they achieve the effect of preventing dust from entering the mesh tube when it is not in use, and at the same time, they achieve the effect of clamping the mesh tube when it is in use. This prevents dust and impurities from entering the mesh tube when it is not in use and causing contamination, or prevents the mesh used for stone removal from being constantly fixed in the palm of the medical staff when the mesh tube is in use, which could interfere with the medical staff's other surgical operations, thus improving the practicality of the device.

[0017] Preferably, a circular plate is fixedly connected to the surface of the square rod, and a rubber pad is fixedly connected to one side of the protective plate.

[0018] The effects achieved by the above components are as follows: the rubber pad increases the sealing performance of the protective plate for dust prevention of the mesh tube, and the round plate prevents the square rod from falling off and detaching from the protective plate.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting a disassembly device, the operating sheath body and the connector can be quickly separated and disassembled. This avoids the situation where the connection between the operating sheath body and the connector is too strong when the staff needs to quickly separate the connector of the collector from the operating sheath body to facilitate the replacement of different operating sheath bodies. This would require time and effort to find and disassemble the tools, which would waste surgical time and thus affect the progress of the operation and endanger the health of the patient. This improves the practicality of the device.

[0021] 2. In this utility model, by setting a protective device, the grid tube in the unused state is protected from dust, and the grid tube in the used state is clamped. This avoids dust and impurities from entering the grid tube when it is not in use and causing contamination, or the grid tube in the used state where the stone retrieval work needs to be fixed in the palm of the medical staff, which would affect the medical staff's other surgical operations. This improves the practicality of the device. Attached Figure Description

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a replaceable operating sheath for a cholangioscope, including an operating sheath body 1, a connector 2 slidably mounted on one side of the operating sheath body 1, a mesh tube 3 connected to the arc surface of the operating sheath body 1, a liquid inlet tube 4 connected to the arc surface of the operating sheath body 1, and a disassembly device 5 provided on the arc surface of the operating sheath body 1. By setting the disassembly device 5, the effect of quickly separating and disassembling the operating sheath body 1 from the connector 2 is achieved, avoiding the problem that when the operator needs to quickly separate the connector 2 connected to the collector from the operating sheath body 1 for easy replacement of different operating sheath bodies 1, the connection between the operating sheath body 1 and the connector 2 is too strong, requiring time and effort to adjust the tools. The retrieval and disassembly operations waste surgical time, affecting the progress of the operation and endangering the patient's health. To improve the practicality of the device, a protective device 6 is provided on the arc surface of the mesh tube 3. By setting the protective device 6, the mesh tube 3 is protected from dust when not in use, and the mesh is clamped when in use. This prevents dust and impurities from entering the mesh tube 3 when it is not in use and causing contamination, or from requiring the mesh to be constantly fixed in the palm of the medical staff when the mesh tube 3 is in use, thus affecting the medical staff's ability to perform other surgical operations. This improves the practicality of the device.

[0029] The following section will explain the specific design and function of the disassembly device 5 and the protective device 6.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the disassembly device 5 includes an L-shaped plate 51, which is fixedly connected to the arc surface of the operating sheath body 1. A connecting block 52 is slidably connected to the surface of the L-shaped plate 51, and the connecting block 52 is fixedly connected to the arc surface of the connector 2. A fixing rod 53 is fixedly connected to the surface of the connecting block 52, and an operating plate 54 is slidably connected to the arc surface of the fixing rod 53. An insertion rod 55 is fixedly connected to one side of the operating plate 54. An insertion hole is opened on the surface of the L-shaped plate 51, and a limit plate 56 is fixedly connected to the end of the fixing rod 53 away from the connecting block 52. The size of the insertion rod 55 is consistent with the size of the L-shaped plate 51. The hole size is compatible. When the operator pulls the operating plate 54, the operating plate 54 slides on the arc surface of the fixed rod 53. At this time, the limiting plate 56 achieves the effect of limiting the maximum sliding distance of the operating plate 54 on the arc surface of the fixed rod 53, preventing the operating plate 54 from detaching from the arc surface of the fixed rod 53 due to excessive pulling force. The arc surface of the fixed rod 53 is fitted with a first spring 57. The two ends of the first spring 57 are fixedly connected to the operating plate 54 and the connecting block 52, respectively. When the operator releases the operating plate 54, the first spring 57... The rebound force causes the operating plate 54 to slide on the arc surface of the fixed rod 53. At the same time, the operating plate 54 drives the insertion rod 55 to move until the insertion rod 55 is inserted into the insertion hole of the L-shaped plate 51. At this time, the first spring 57 improves the stability of the insertion rod 55 when it is limited by the L-shaped plate 51. A rubber ring 58 is fixedly connected to the surface of the operating plate 54. The rubber ring 58 is slidably connected to the arc surface of the fixed rod 53. When the operator moves the operating plate 54, the operating plate 54 drives the rubber ring 58 to slide on the arc surface of the fixed rod 53. The elasticity of the rubber ring 58 wraps around the fixed rod 53, thereby reducing the impact of the operating plate 54 on the fixed rod 53. The sliding speed on the arc surface of the fixed rod 53 reduces the impact of external shaking on the operating plate 54, thus achieving a damping effect. The surface of the L-shaped plate 51 is fixedly connected to the positioning block 59, which is slidably connected to one side of the connecting block 52. When the worker pushes the L-shaped plate 51, the L-shaped plate 51 slides inside the connecting block 52 until the positioning block 59 and one side of the connecting block 52 are in contact. At this time, the position of the L-shaped plate 51 inserted into the connecting block 52 is positioned, so that the worker can quickly insert the insertion rod 55 into the L-shaped plate 51, thus improving the worker's work efficiency.

[0031] Reference Figure 4 and Figure 5As shown, specifically, the protective device 6 includes a support plate 61, which is fixedly connected to the arc surface of the mesh tube 3. A rotating rod 62 is fixedly connected to the upper surface of the support plate 61. A protective plate 63 is rotatably connected to the end of the rotating rod 62 away from the support plate 61. A square rod 64 is slidably inserted into the protective plate 63. Two square holes are opened on the surface of the support plate 61. A circular plate 65 is fixedly connected to the surface of the square rod 64. A rubber pad 66 is fixedly connected to one side of the protective plate 63. The rubber pad 66 increases the sealing performance of the protective plate 63 when it is dustproof to the mesh tube 3. The circular plate 65 prevents the square rod 64 from falling off the protective plate 63.

[0032] Working principle: When it is necessary to disassemble the connection between connector 2 and operating sheath body 1, the operator pulls the operating plate 54. The operating plate 54 overcomes the elastic force of the first spring 57 and slides on the arc surface of the fixed rod 53, driving the insertion rod 55 to be pulled out from the insertion hole of the L-shaped plate 51, releasing the limitation on the connecting block 52, and the disassembly is completed. When quick connection is required, the L-shaped plate 51 can be pushed to slide in the connecting block 52. When the positioning block 59 is in contact with one side of the connecting block 52, the insertion position of the L-shaped plate 51 is accurately positioned, which is convenient for subsequent reconnection. At this time, the operating plate 54 is released, the first spring 57 releases the rebound force, and drives the operating plate 54 and the insertion rod 55 to return to their original positions. During this process, the rubber ring 58 uses its elasticity to wrap the fixed rod 53, slowing down the sliding speed of the operating plate 54 and reducing external shaking interference. At the same time, the first spring 57 enhances the limiting stability of the insertion rod 55 on the L-shaped plate 51.

[0033] Rotate the protective plate 63 so that it rotates around the rotating rod 62 to cover the mesh tube 3. Then insert the square rod 64 into the protective plate 63 and pass it through the square hole of the support plate 61. Use the round plate 65 to prevent the square rod 64 from falling off, thus fixing the protective plate 63. The rubber pad 66 fits tightly against the mesh tube 3 to enhance dustproof sealing and effectively prevent dust from entering the mesh tube 3. If it is necessary to remove the protection, pull out the square rod 64 and rotate the protective plate 63 away from the mesh tube 3, thereby completing the protection and removal operation of the mesh tube 3 and ensuring the normal operation of the mesh tube 3.
