Description

Technical Field

[0001] The utility model relates to the technical field of stent implantors, and particularly relates to a medical stent implantor. Background Art

[0002] Digestive tract tumors are a common type of tumor, which may cause digestive tract stenosis due to the growth of the tumor, seriously affecting the digestive function and quality of life of patients. At present, stent implantation is an effective method for treating digestive tract stenosis, which restores the patency of the digestive tract by placing a stent at the stenotic site.

[0003] The current stent implantation process usually relies on X-rays or endoscopes as guiding tools. Although X-rays can provide clear image guidance, it involves a certain risk of radiation exposure, which is an issue that cannot be ignored for both patients and medical staff. On the other hand, although the use of an endoscope can provide direct visual feedback, operating the implantor and the endoscope simultaneously requires the operator to have excellent skills and experience, which increases the complexity and difficulty of the surgery.

[0004] In addition, due to the diversity of the shape and location of the tumor, medical staff may need to continuously adjust the position and direction of the implantor during the operation to ensure that the stent can be accurately placed at the stenotic site, which not only increases the operation time but also may increase the workload and operation risk of medical staff. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a medical stent implantor to solve the challenges in visual feedback and adjustment functions existing in the use of stent implantors in the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A medical stent implantor includes a flexible tube and an adjustable positioning assembly. The flexible tube has a working end, and the working end has a first channel, and the first channel is adapted to install a first component. The adjustable positioning assembly has a camera and a swinging member. The camera is arranged on the working end, and the swinging member is arranged on the flexible tube. The swinging member has a swinging end, and at least part of the swinging end is connected to the working end and is adapted to swing the working end in multiple directions. Among them, in the state where the working end swings, the first channel and the camera swing simultaneously.

[0008] Furthermore, the swinging end has a plurality of swinging parts, which are sequentially swing-connected along a first direction, and a plurality of the swinging parts are selectively connected to the working end.

[0009] Further, the swinging part has a supporting surface which is adapted to abut against the hose to form a stress area. Along the second direction, both the camera and the first channel have projections within the stress area.

[0010] Further, along the extending direction of the working end, a second channel is formed in the working end. The second channel is adapted to install a camera, and the axes of the first channel and the second channel are parallel.

[0011] Further, the working end has a plurality of receiving cavities which are respectively arranged outside the first channel and the second channel. The receiving cavities are adapted to assemble the swinging members.

[0012] Further, the working end has a first assembly section and a second assembly section. A part of the receiving cavity is arranged on the first assembly section, and another part of the receiving cavity is arranged on the second assembly section. In the assembled state, the first assembly section and the second assembly section are in sealing contact.

[0013] Further, the swinging member has a plurality of mounting points, and the camera is selectively connected to the plurality of mounting points.

[0014] Further, the second channel has a flanging which is arranged towards the inner side of the second channel.

[0015] The advantages of the medical stent implanter of the present utility model over the prior art are as follows:

[0016] By providing real-time images of the surgical area through the built-in camera, it helps medical staff to more accurately observe and evaluate the stenosis site, thereby improving the accuracy and safety of the surgery.

[0017] The design of the swinging member allows the working end to swing in multiple directions, enabling the implanter to turn according to the patient's anatomical structure, reducing the number and complexity of adjusting the implanter's posture during the surgery.

[0018] The synchronous swing of the first channel and the camera ensures that when adjusting the implanter's posture, the placement of the stent and the visual feedback always remain consistent, which helps to quickly locate the placement of the stent, improves the overall efficiency of the surgery, and shortens the operation time.

Detailed implementation manner

[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Embodiment 1, referring to Figures 1 - 2 , a medical stent implantor provided in this embodiment includes a hose 10 and an adjustable positioning assembly. The hose 10 is made of medical-grade plastic, has good biocompatibility and flexibility to adapt to different anatomical structures. One end of the hose 10 is connected with an operation handle, and the other end is a working end 101. Along the length direction of the hose 10, a first channel 1011 is arranged in the hose 10. The first channel 1011 extends into the working end 101 of the hose 10 and forms an outlet at the front end of the working end 101. The first channel 1011 is used to install and guide the first component, that is, the stent.

[0029] The adjustable positioning assembly has a camera 20 and a swinging member 30. The camera 20 can be a micro camera 20, also known as an endoscopic camera 20, which is precisely integrated at the front end of the working end 101. This high-resolution camera 20 adopts advanced imaging technology and can capture clear and real-time images of the surgical area. The camera 20 is connected to an external monitor or an image processing system through a thin and flexible cable. This cable is designed to be thin enough to reduce the impact on the flexibility of the hose 10 while maintaining the stability and clarity of image transmission.

[0030] The swinging member 30 is disposed on the flexible hose 10. The swinging member 30 has a swinging end, and at least part of the swinging end is connected to the working end 101 and is adapted to swing the working end 101 in multiple directions. After the working end 101 swings, the steering adjustment of the flexible hose 10 can be achieved. Considering the flexible characteristics of the flexible hose 10, at least part of the swinging end needs to be connected to the working end 101. This design ensures that the swinging end can provide sufficient steering force for the working end 101.

[0031] During the operation, the swinging end drives the working end 101, the first channel 1011, and the camera 20 to swing synchronously. This synchronous mechanism can ensure that the camera 20 can provide accurate visual feedback in any swinging state.

[0032] Through the above design, the multi-directional swinging ability of the working end 101, combined with the real-time feedback of the camera 20, enables the implantor to flexibly adapt to complex surgical environments, especially when dealing with irregular or difficult-to-reach anatomical regions. At the same time, due to the efficient integration of the steering adjustment and visual feedback of the implantor, the surgical process is optimized, the number of times of adjusting the instruments during the operation is reduced, thereby shortening the operation time. Moreover, the synchronous swinging mechanism ensures the precise synchronization of the camera 20 and the working end 101, enabling medical staff to accurately observe the real-time position of the stent and the state of the surgical area, greatly improving the accuracy of the operation.

[0033] In some embodiments, the swinging end has a plurality of swinging parts 301. Along the first direction, where the first direction refers to the axial direction of the flexible hose 10, the plurality of swinging parts 301 are sequentially swing-connected. The swing connection of the plurality of swinging parts 301 can be achieved by means such as hinging, allowing each swinging part 301 to swing independently. Through the collaborative work of the plurality of swinging parts 301, fine adjustment of the working end 101 can be achieved, including minute adjustments on multiple planes to adapt to complex surgical environments. Each swinging part 301 can be designed modularly, enabling selective connection to the working end 101 according to surgical needs, providing higher flexibility and adaptability.

[0034] In some other embodiments, the swinging member 30 can adopt an endoscopic snake bone. The endoscopic snake bone adopts a special structural design and is commonly used for the flexible adjustment of endoscopes, providing flexibility similar to that of a snake's spine. The endoscopic snake bone usually adopts elastic materials such as spring steel or memory alloy. These materials have excellent flexibility and bendability and can return to their original state after being stressed. The endoscopic snake bone is composed of multiple segments, and each segment is connected by means of hinging or similar joints, allowing the segments to move freely within a certain range. The endoscopic snake bone can be adjusted by an external force. By pulling the external force, the steering of the endoscopic snake bone can be controlled.

[0035] In specific implementation, the endoscope snake bone can be sleeved on the working end 101 of the hose 10. The fixation between the endoscope snake bone and the working end 101 of the hose 10 can adopt methods such as riveting, welding or mechanical locking to ensure stability during the operation. The inner diameter of the endoscope snake bone is precisely adapted to the outer diameter of the working end 101 of the hose 10 to ensure that the outer wall of the working end 101 of the hose 10 abuts against the inner wall of the endoscope snake bone after assembly, and a stress area is formed between the two. At this time, the inner wall of the endoscope snake bone forms a support surface, providing stable support and precise steering control. At the same time, a number of guide wires can be fixedly installed on the endoscope snake bone. When the working end 101 of the hose 10 enters the patient's digestive tract, the end of the guide wire is located outside the patient's body, and medical staff can control the steering of the working end 101 of the hose 10 by simply pulling the guide wire.

[0036] It is worth noting that along the second direction, where the second direction refers to the direction perpendicular to the stress area, both the camera 20 and the first channel 1011 have projections within the stress area. That is to say, the camera 20 can be installed on the outer wall of the endoscope snake bone to ensure synchronous steering adjustment with the first channel 1011 and provide real-time image feedback.

[0037] Through the above design, the flexibility of the medical stent implantator is improved, enabling it to adapt to complex anatomical structures. Moreover, the synchronous steering adjustment and real-time image feedback make the surgical operation more precise and improve the success rate of the surgery.

[0038] Embodiment 2, refer to Figures 3 - 5 , based on the above embodiment, the working end 101 is provided with a second channel 1012 along the extending direction, where the second channel 1012 is specifically used for installing the camera 20. This design helps to reduce the overall volume of the working end 101 and reduce the interference to the patient's digestive tract. The second channel 1012 can extend to the connection end of the hose 10, that is, the end of the hose 10 far from its working end 101, which is convenient for connecting the camera 20 to an external display or image processing system, simplifies the surgical preparation process, and at the same time, the first channel 1011 and the second channel 1012 are axially parallel, which can ensure adjustment consistency, synchronize the steering adjustment and visual feedback of the device, and improve the coordination and precision of the surgery.

[0039] In some embodiments, the working end 101 has a plurality of receiving cavities 40, which are arranged outside the first channel 1011 and the second channel 1012 and are used for assembling the swinging member 30, such as the endoscope snake bone, further ensuring the compactness of the device. The receiving cavity 40 can be designed as an annular cavity. One end of the receiving cavity 40 away from the operating handle is closed to reduce the impact on the patient, and at the same time, it can prevent the patient's body fluid from entering the receiving cavity 40 and damaging the swinging member 30. The other end of the receiving cavity 40 extends to the end of the hose 10 near the handle to facilitate the control of the swinging member 30. For example, when the swinging member 30 is an endoscope snake bone, the guide wire can be led out from the other end of the annular cavity.

[0040] In some other embodiments, the working end 101 has a first assembly section 50 and a second assembly section 60. A part of the receiving cavity 40 is arranged on the first assembly section 50, and another part of the receiving cavity 40 is arranged on the second assembly section 60. And in the assembled state, the first assembly section 50 and the second assembly section 60 are in sealed contact.

[0041] When assembling the swinging member 30, insert one end of the swinging member 30 into the receiving cavity 40 on the first assembly section 50 and ensure that the swinging member 30 is correctly aligned with this part of the receiving cavity 40. At this time, the other end of the swinging member 30 should be located outside the hose 10. Then, sleuth the second assembly section 60 on the other end of the swinging member 30. After the second assembly section 60 is in place, adjust the position of the second assembly section 60 and make it in close contact with the first assembly section 50. Finally, use fastening components such as bolts to fixedly connect the swinging member 30 with the working end 101 of the hose 10.

[0042] Through the above design, the volume of the working end 101 is reduced, the interference with the patient's digestive tract is reduced, the comfort of the patient is improved, and at the same time, the modular assembly design reduces the surgical preparation and assembly time and improves the surgical efficiency.

[0043] Embodiment 3, referring to Figures 6 - 7 , based on the above embodiments, the swinging member 30 is equipped with a plurality of preset installation points 70, which can be designed as standardized threaded holes and allow connection with the camera 20 at different positions. The hose 10 and the camera 20 are also equipped with corresponding threaded holes.

[0044] When assembling, first align the camera 20 with the entrance of the second channel 1012 and push it into the channel until it reaches the predetermined position. Then, assemble the swinging member 30. After adjusting the position and aligning all the threaded holes, select a suitable bolt to pass through the threaded holes and use an appropriate tool (such as a wrench or a screwdriver) to tighten the bolt to realize the fixation of the swinging member 30 with the hose 10 and the camera 20.

[0045] In some embodiments, the second channel 1012 has a flange 80, which is arranged toward the inner side of the second channel 1012. After assembly is completed, one end of the camera 20 fits tightly against the flange 80. This design can provide additional support and protection for the camera 20 or other components passing through the second channel 1012. The flange 80 can also serve as a positioning feature to help fix the position of the camera 20 and prevent it from moving or rotating in the second channel 1012, thereby ensuring image stability. Moreover, the flange 80 can provide a sealing effect to prevent body fluids or other foreign substances from entering the second channel 1012, thereby protecting the camera 20 from contamination.

[0046] Through the above design, the assembly and adjustment process of the device is simplified, the surgical preparation time is reduced, the medical staff can perform the surgery more efficiently, the structural stability and functionality of the medical stent implanter are enhanced, and additional safety and operational convenience are provided for the surgical process.

[0047] Working principle:

[0048] First, the bracket is loaded into the first channel 1011 in the hose 10, and then the camera 20 is installed in the second channel 1012. After the bracket and the camera 20 are installed in place, the swing member 30 is assembled. The swing member 30 realizes the connection between the hose 10 and the camera 20 through its installation point 70.

[0049] During the operation, the hose 10 is slowly introduced into the patient's digestive tract. Through the real-time image provided by the camera 20, medical staff can observe the internal conditions of the digestive tract and ensure that the hose 10 is correctly navigated to the target position.

[0050] When the working end 101 of the hose 10 needs to be turned to adapt to the anatomical structure of the digestive tract, the working end 101 of the hose 10 is controlled to make corresponding steering adjustments. During the steering process, the camera 20 not only provides visual feedback, but also helps medical staff to accurately adjust the position of the working end 101 to ensure that it accurately reaches the predetermined surgical area. Once the working end 101 of the hose 10 reaches the target position, the stent is released by operating the handle, and the stent will be accurately placed in the narrow part of the digestive tract to restore the patency of the passage. After releasing the stent, the camera 20 is used again to confirm the position and status of the stent to ensure that it is correctly deployed and performs its function. After confirming that the stent is correctly placed and functions normally, the hose 10 is slowly withdrawn to complete the surgical procedure.

[0051] When referring to multiple illustrative embodiments in this specification, it means that the specific structures described in connection with each such embodiment are included in at least one of the embodiments generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a structure in connection with any one embodiment, it is intended that the implementation of such a structure in combination with other embodiments fall within the scope of the present utility model.
