Description

Technical Field

[0001] The present invention relates to the field of medical equipment, and in particular to a medical system. Background Art

[0002] In the field of clinical disease diagnosis, especially for tumor diagnosis, tissue biopsy technology plays a vital role. This technology directly inserts a puncture needle into the suspected tumor site to obtain tissue samples for pathological analysis, thereby helping doctors accurately determine the nature of the lesion and providing a scientific basis for the selection of subsequent treatment options.

[0003] However, the biopsy process is not completely risk-free. During the process of withdrawing the puncture needle from the body, it may carry a small amount of tumor cells along the needle tract, a phenomenon known as needle tract seeding. Once this happens, these tumor cells may grow along the puncture path and form new lesions, which in turn increases the complexity of the patient's condition and the difficulty of treatment. Therefore, before performing a biopsy, doctors need to fully assess the potential risks and take appropriate preventive measures to minimize the possibility of tumor cells spreading along the puncture path and ensure patient safety.

[0006] According to one embodiment of the present application, the anti-diffusion device can pre-treat the diseased cells before the ablation device ablates to prevent the diseased cells contaminated on the anti-diffusion device from spreading when the anti-diffusion device is withdrawn from the tissue.

[0007] According to one embodiment of the present application, the anti-diffusion device can partially enter the tissue, and the destructive component is located at the head end of the anti-diffusion device and can receive the destructive energy provided by the anti-diffusion device.

[0008] According to one embodiment of the present application, a passage is provided on the destroying component, and the energy head of the anti-diffusion device passes through the passage to destroy the diseased cells.

[0009] According to one embodiment of the present application, the destroying component is a puncture needle, which receives energy from the energy head to destroy the diseased cells.

[0010] According to one embodiment of the present application, a puncture needle guiding structure is also included. The puncture needle guiding structure includes two groups of disc structures, and the axes of the two groups of disc structures coincide.

[0011] According to one embodiment of the present application, each group of disc structures includes two parallel discs and a ball joint, the ball joint is arranged between the two discs, and curved grooves are arranged on the two discs. The ball joint moves along the two curved grooves; the puncture needle passes through the ball joint and can rotate along the plane driven by the ball joint.

[0012] According to an embodiment of the present application, the two curved grooves are perpendicular to each other at any intersection, and the ball joint is located at the intersection.

[0013] According to one embodiment of the present application, each disk is driven by a separate piezoelectric motor.

[0014] According to one embodiment of the present application, the ablation device includes a catheter and a catheter head end, the catheter head end has a plurality of struts, and each strut has a plurality of electrodes.

[0015] According to one embodiment of the present application, the catheter tip also includes a strut cap, a plurality of struts are evenly distributed and fixedly connected to the distal end of the catheter, and the other end of each strut is connected to each other through the strut cap.

[0018] According to one embodiment of the present application, a channel three for a wire to pass through is further provided in the catheter, the wire is connected to the electrode on the strut, and the number of the channels three corresponds to the number of the struts.

[0028] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] It should be noted that the front and rear directions in the present application refer to the front and rear directions of the user, the proximal end refers to the end close to the user, and the distal end refers to the end far away from the user.

[0030] The present application provides a medical system, including an anti-diffusion device and an ablation device. The anti-diffusion device has a destruction component, and the ablation device has an energy component. The destruction component can destroy diseased cells in tissues, so that the diseased cells will not contaminate and spread before the energy component of the ablation device ablates the tissues.

[0031] In one embodiment, an energy head is further provided on the anti-diffusion device, and the destroying component is a puncture needle. The puncture needle has a passage. The puncture needle receives energy from the energy head to destroy the diseased cells, thereby disinfecting the diseased cells.

[0032] Since manual puncture relies on the skills and experience of the operator, it may lead to inaccurate location of sample acquisition, increasing the risk of missed diagnosis or misdiagnosis. In order to improve the accuracy of puncture, a medical system of the present application also includes a puncture needle guide structure, which reduces the risk of damage to surrounding tissues by precisely controlling the position and angle of the puncture needle tip, thereby improving the accuracy and safety of biopsy.

[0033] Please refer to Figure 1 The puncture needle guide structure includes two sets of disc structures 3 and a drive motor, wherein the axes of the two sets of disc structures 3 completely overlap. This design ensures the coordinated movement of the discs and avoids the movement error caused by axis deviation. The drive motor is a piezoelectric motor, which can keep the disc structure in the current position after power failure, ensuring the safety of clinical operation.

[0034] Please continue reading Figure 1Each set of disc structures 3 includes two parallel discs 3-1 and a ball joint 3-2. The ball joint 3-2 is arranged between the two discs 3-1. Each disc 3-1 is provided with a curved groove 3-3. The ball joint 3-2 is embedded in the two curved grooves 3-3. The puncture needle 5 passes through the ball joint 3-2. The ball joint 3-2 moves in the curved groove 3-3 of the disc 3-1. The position of the ball joint 3-2 is determined by the intersection of the two curved grooves 3-3. The ball joint 3-2 can move along a preset path when the two discs 3-1 rotate. This design restricts and guides the movement of the ball joint 3-2 in the air. The movement of the ball joint 3-2 drives the puncture needle 5 to move accurately, ensuring that the movement path of the puncture needle 5 always remains on the predetermined trajectory.

[0035] In one embodiment, the curved grooves 3-3 on the two disks 3-1 where the ball joint 3-2 is located are perpendicular to each other, so that the two curved grooves 3-3 remain perpendicular at any intersection, ensuring the precise positioning of the ball joint and helping to stabilize the movement of the puncture needle 5; since the outer surface of the ball joint 3-2 has less friction with the curved groove 3-3, the rotation of the puncture needle 5 will be smoother, and the inner side of the ball joint 3-2 can stabilize the needle guide to control the rotation and movement of the puncture needle 5.

[0036] In one embodiment, the rotation of the disk 3 - 1 is directly driven by a motor, one disk 3 - 1 is driven by one motor, and the motor is connected to a controller, and the controller can control the movement of each disk 3 - 1 individually.

[0037] In one embodiment, the two sets of disc structures 3 can be fixedly supported by a frame and a base. The disc structure 3 can rotate freely on the frame under the drive of a motor. The base is provided with mounting holes corresponding to the frame, and bolts pass through the mounting holes to firmly fix the frame on the base. This method is simple and reliable, and is easy to disassemble and maintain.

[0038] In one embodiment, a height adjustment device is provided on the base to fine-tune the height of the double trays during installation to ensure that they are on the same level.

[0039] In one embodiment, the puncture needle guiding structure further includes an optical sensor for detecting the initial position of the disk 3 - 1 to ensure that each start-up starts from the initial position.

[0040] The puncture needle guide structure of the present application adopts two groups of disc structures 3, each group of disc structures 3 includes two discs 3-1 and a ball joint 3-2, and the discs 3-1 are each provided with a curved groove 3-3, and the ball joint 3-2 is arranged at the intersection of the curved grooves 3-3 of the two discs 3-1. This design avoids the use of complex mechanical mechanisms such as gears and robotic arms. At the same time, the double disc structures are stacked in parallel and occupy very little space, which greatly reduces the size and complexity of the system. It is suitable for use in the limited space of an imaging device, and with the help of the imaging device, the puncture efficiency is improved and the risk of tumor implantation is reduced.

[0041] The ablation device of the present application is intended to ablate tumor tissue efficiently and accurately. The ablation energy may be energy in the form of pulse, radio frequency or ultrasound.

[0042] In one embodiment, see Figure 2 The ablation device includes a catheter 1 and a catheter head 2. The catheter head 2 is arranged at the distal end of the catheter 1. The catheter 1 serves as the main part of the ablation device and is used to accurately deliver the catheter head 2 to the target position. The catheter head 2 is a key component for achieving the ablation effect.

[0043] See also Figure 2-Figure 3 The catheter tip 2 includes a plurality of struts 2-1 and a strut cap 2-2. The plurality of struts 2-1 are evenly distributed and fixedly connected to the distal end of the catheter 1 to form a stable support structure. The other end of each strut 2-1 is connected to each other through the strut cap 2-2, together forming a structure that can effectively expand and contact the target tissue. The design of the strut cap 2-2 not only ensures the stable connection between the struts 2-1, but also enables the entire catheter tip 2 to adjust its shape according to actual needs to better adapt to tumor tissues of different forms.

[0044] Each strut 2-1 is equipped with several electrodes, which are evenly spaced to ensure uniform energy distribution. The energy transmitted by these electrodes can generate highly concentrated force in the target area, thereby effectively ablating tumor cells while maximally protecting surrounding healthy tissues from damage.

[0045] See also Figure 4 , a channel 1-1 is provided in the center of the catheter 1, and the channel 1-1 is used for the guide wire to pass through. One end of the guide wire is fixed to the handle part of the catheter 1, which is convenient for the operator to control; the other end passes through the proximal end of the channel 1-1, passes through the entire length of the catheter 1, passes through the distal end, and is finally fixed to the support rod cap 2-2 located at the catheter head end 2. In this way, the operator can apply different pulling or pushing forces to the guide wire through the handle part, so as to accurately control the expansion and folding state of the support rod 2-1.

[0046] Specifically, in order to ensure that the guide wire can be firmly connected to the support rod cap 2-2, an insertion point is set on the support rod cap 2-2, and the guide wire is fixed to the support rod cap 2-2 through the insertion point, ensuring that the guide wire will not fall off easily even if a large force is applied during operation. When it is necessary to unfold the support rod 2-1, the operator only needs to gently pull the guide wire, and the tension of the guide wire will cause the support rod cap 2-2 and the connected support rod 2-1 to expand outward until a predetermined unfolded state is reached. On the contrary, when it is necessary to fold the support rod 2-1, the support rod cap 2-2 and the support rod 2-1 can be retracted into the catheter 1 by loosening the guide wire or pushing the guide wire inward to facilitate the insertion or removal of the catheter.

[0047] This design not only improves the operational flexibility of the catheter 1 in the body, but also enhances the safety and accuracy of the treatment process, allowing doctors to more easily position the catheter head 2 to the target position, while ensuring that the strut 2-1 can be quickly deployed after reaching the predetermined position, thereby achieving effective ablation of tumor tissue.

[0048] In one embodiment, the handle is also provided with a locking mechanism, and during surgery, the doctor first adjusts the position of the guide wire through the adjustment device on the handle to control the expansion degree of the strut 2-1. When the strut 2-1 reaches the desired shape, the doctor can fix it through the locking mechanism on the handle.

[0049] See also Figure 4-5 The catheter 1 is also provided with a channel 2 1-2 through which a control line passes. There are multiple channels 1-2, which are symmetrically arranged inside the catheter 1. One end of the control line is fixed to the handle part for easy operation by the doctor, and the other end passes through the channel 2 1-2 and is fixed to the distal end of the catheter 1.

[0050] Furthermore, in order to facilitate the control of the deflection of the catheter 1, the portion of the catheter 1 close to the catheter head end 2 is configured to be bendable, while the remaining portion maintains a high rigidity. By applying different pulling forces or pushing forces to the control wire of the handle portion, the doctor can accurately control the deflection angle of the distal end of the catheter.

[0051] For further information, please refer to Figure 5 In order to facilitate the control of deflection, the channel 2 1-2 is bent outward at a section near the catheter head end 2. This design makes it easier for the portion of the catheter 1 near the catheter head end 2 to deflect while maintaining the rigidity of the rest of the catheter 1. In addition, by bending the channel 2 1-2 outward when approaching the catheter head end 2, the force required to deflect the catheter 1 is reduced, allowing the doctor to better control the position and direction of the catheter head end 2.

[0052] Please continue reading Figure 4-5The catheter 1 is also provided with channels 1-3 through which wires pass. The number of channels 1-3 corresponds to the number of struts 2-1, ensuring that each strut 2-1 has an independent wire connected to it. The proximal ends of these wires are connected to the handle part, while the distal ends pass through the channels 1-3 and are electrically connected to the electrodes on the struts 2-1.

[0053] The electrodes on each strut 2-1 are connected to the power source through an independent wire. This design ensures that each strut 2-1 can be selectively energized. Doctors can selectively activate specific electrodes according to the specific location and size of the lesion tissue, thereby achieving precise ablation of the lesion tissue and reducing damage to surrounding normal tissues.

[0054] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
