Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0045] With the increasing maturity and widespread adoption of minimally invasive ablation technologies such as microwave and radiofrequency ablation, minimally invasive ablation therapy for tumors has become widely used in clinical practice. After minimally invasive ablation, the burned tumor tissue remains in the body. While the uncharred portion can be absorbed and digested by the body over time, the charred tissue cannot be absorbed and will persist in the body for a long period. For some superficial tumors, such as breast cancer or thyroid cancer, especially for large ablated tissue (e.g., larger than 3 cm), the long-term presence of charred tissue after minimally invasive ablation has adverse effects on the patient's physical and psychological well-being, hindering postoperative recovery and normal life. There is a widespread clinical need to remove charred tissue after surgery. Currently, there are no medical devices on the market specifically designed to address this clinical need.

[0046] In view of this, please see Figures 1 to 7The medical rotary erosion device provided in this embodiment of the invention includes a guiding puncture mechanism 100 and a rotary erosion mechanism 200. The guiding puncture mechanism 100 includes a guiding component 110 and a puncture component 120. The rotary erosion mechanism 200 includes a rotary erosion bar 201 and a driving member 203. The driving member 203 is operatively connected to the rotary erosion bar 201 to drive the rotary erosion bar 201 to rotate. The rotary erosion bar 201 has a first channel 2011 extending axially along the rotary erosion bar 201. The medical rotary erosion device includes a puncture state and a rotary erosion state. When the medical rotary erosion device is in the puncture state, one end of the puncture component 120 is connected to the guiding component 110, and the other end extends out of the guiding component 110. When the medical rotary erosion device is in the rotary erosion state, one end of the rotary erosion bar 201 extends out of the guiding component 110, and the other end is operatively connected to the driving member 203. When using this medical rotary abrasion device, firstly, the puncture component 120 is installed on the guide component 110, putting the device in a puncture state. The puncture component 120 is then used to puncture the skin to reach the affected area. Next, the puncture component 120 is removed, leaving the guide component 110 at the affected area. Then, the rotary abrasion blade 201 of the rotary abrasion mechanism 200 is passed through the guide component 110, with the blade tip of the blade 201 positioned at the affected area, putting the device in a rotary abrasion state. The drive component 203 is then activated, causing the rotary abrasion blade 201 to rotate, thus abrading the charred tissue at the affected area. The abraded fragments flow out from the first channel 2011 of the rotary abrasion blade 201, achieving postoperative treatment of charred tissue. The puncture component 120 punctures the skin, allowing the guide component 110 to reach the affected area, and the guide component 110 guides the rotary abrasion blade 201. This medical rotary abrasion device has a simple structure, minimal wound damage, and high safety.

[0048] In an optional embodiment of the present invention, the driving member 203 includes a driving shaft, and the driving shaft has a second channel; the grinding tool bar 201 passes through the second channel and is connected to the driving member 203 in a transmission manner.

[0049] Specifically, the drive component 203 is configured as a hollow stepper motor, servo motor, or DC motor, and the maximum torque of the motor cannot cause the muscle tissue to become kinked. Furthermore, the reaming scalpel handle 201 is made of high-strength medical stainless steel tubing such as 0Cr17Ni4Cu4Nb (SUS630) or 9Cr18Mo (SUS440C), which has high strength after heat treatment; and one end of the reaming scalpel handle 201 extending from the guide component 110 is configured as a reaming blade, or a welded reaming blade head, with a sharp blade head capable of grinding tumor tissue into fragments under rapid rotation. More preferably, the diameter of the reaming scalpel handle 201 is set to 1.5-2.5 mm; the length of the reaming scalpel handle 201 is set to 150-220 mm; of course, other dimensions for the diameter and length of the reaming scalpel handle 201 should also be within the protection scope of this embodiment.

[0050] The drive shaft has a second channel to prevent the drive shaft from blocking the first channel 2011 of the swirl grinder 201, thereby preventing the material swirls through the swirl grinder 201 from flowing out of the first channel 2011.

[0051] In an optional embodiment of the present invention, the swirl grinding mechanism 200 further includes a housing 210, one end of the swirl grinding bar 201 extends out of the housing 210, and the other end is connected to the drive member 203 located inside the housing 210.

Preferably, the filter element 224 and the observation window 221 are sealed by a second O-ring 223; the diameter of the filter screen inside the filter element 224 is set to 0.5-1 mm to filter tissue fragments larger than 1 mm in diameter. Furthermore, the filter element 224 and the observation window 221 are fixed by snap-fit ​​mechanisms, allowing for quick disassembly and removal of the filter element 224 to clean the filtered tissue fragments; of course, the bonding of the filter element 224 to the observation window 221, etc., should also be within the scope of protection of this embodiment of the invention.

[0059] Filter element 224 filters tissue fragments.

[0060] In an optional embodiment of the present invention, the swirl grinding mechanism 200 further includes a first dynamic seal 202 and a second dynamic seal 204.

The first dynamic seal 202 and the second dynamic seal 204 are respectively located on both sides of the drive member 203.

[0061] Specifically, both the first dynamic seal 202 and the second dynamic seal 204 are configured as skeleton rotary seals, and the skeleton rotary seals need to ensure sealing at a working speed of 1000 r / min. The first dynamic seal 202 is located on the front side of the drive member 203, forming a water inlet isolation semi-enclosed area between itself and the outer wall of the housing 210 and the grinding rod 201; the second dynamic seal 204 is located on the rear side of the drive member 203, forming a negative pressure isolation semi-enclosed area with the housing 210, the outer wall of the grinding rod 201, and the observation filter.

[0062] The first dynamic seal 202 and the second dynamic seal 204 achieve a sealing effect between the housing 210 and the grinding tool holder 201, protecting the drive component 203 and control circuit inside the housing 210, and ensuring reliable sealing.
