The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0043] In one embodiment, an axillary tissue resection device is provided. The axillary tissue resection device includes an actuator and a pressing piece. The actuator portion of the actuator can be inserted into the axillary tissue. The actuator has an incision and a cutter. The pressing portion of the pressing piece can squeeze the axillary tissue from the outer surface of the axillary tissue into the incision. The cutter in the incision rotates or moves linearly to achieve resection of the squeezed axillary tissue. The resection process is gradual squeezing and layer-by-layer resection.

[0044] Among them, the incision of the execution part is set to be circular, the pressing part is set to be spherical, and the ratio of the diameter of the pressing part to the diameter of the incision is limited, so that when the pressing part and the incision squeeze the tissue, the thinner axillary tissue can be controlled to be squeezed to the inside of the incision in an arc shape, thereby achieving multiple ultra-thin resections of the axillary tissue, avoiding squeezing too much axillary tissue into the incision, preventing the tissue from being squeezed into wrinkles, and preventing too much tissue from being removed at one time, thereby achieving more precise and effective resection and avoiding harm to the patient.

[0045] Please refer to Figures 1 to 4 The axillary tissue resection device of this embodiment mainly includes a handle 1, an actuator 2, a pressing member 3 and a handle 4.

[0046] The handle 1 may be a long columnar structure, with a receiving cavity in the handle 1, and a driver may be installed in the receiving cavity of the handle 1. Of course, components such as batteries may also be installed in the receiving cavity of the handle 1.

[0047] The handle 1 includes a front end and a rear end in the length direction, the front end refers to the end close to the patient, and the rear end refers to the end away from the patient. A mounting hole is provided at the front end of the handle 1, and a driver is provided near the mounting hole of the handle 1. The driver may include a driving mechanism such as a motor, and the driver may also include a transmission connection structure such as a coupling.

[0048] The axillary tissue removal device also includes a host, and the handle 1 can be connected to the host by wire or wireless means, and the host can charge the components in the handle 1 and transmit data. A controller is provided in the host, and the controller can be a PCB circuit board, and the controller has control and processing functions. The controller can be preset with a removal program, which can realize automatic removal of the axillary tissue removal device. Of course, the axillary tissue removal device can also manually or semi-automatically remove the axillary tissue 5.

[0049] In other embodiments, the controller may be disposed in the handle 1, or a sub-controller may be disposed in the handle 1 and a main controller may be disposed in the host. The sub-controller in the handle 1 is used to control the rotation of the driver, and the main controller in the host is used for real-time detection and calculation functions to prevent the handle 1 from overheating.

[0050] In this embodiment, the actuator 2 is a long tubular structure, specifically a thin tube structure, so that the actuator 2 can be inserted into the axillary tissue 5. One end (front end) of the actuator 2 is an actuator 21, which is used to remove subcutaneous tissue, and the other end (rear end) of the actuator 2 is a connecting part, which is inserted into the mounting hole of the handle 1.

[0051] The circumferential side of the execution part 21 is provided with an incision 211, which can be a circular incision. When the execution part 21 is inserted into the axillary tissue 5 of the patient, the pressing member 3 can squeeze the axillary tissue 5 from the outside of the axillary tissue 5 into the incision 211 to achieve the excision of the axillary tissue 5.

[0052] A cutter 22 is provided in the actuator 2 , and a first end of the cutter 22 extends into the handle 1 and is connected to a driver, so that the driver can drive the cutter 22 to move and cut off the subcutaneous tissue of the armpit squeezed into the incision 211 .

[0053] The cutter 22 may be a spiral cutter, the outer diameter of which is equal to or close to the inner diameter of the tubular actuator 2, and the spiral cutter may be rotatably arranged along the axial direction of the tubular actuator 2, and the driver may drive the spiral cutter to rotate, and the spiral cutter may cut the axillary tissue 5 by rotating.

[0054] In other embodiments, the execution part 21 may also be a straight knife, which can be arranged to move linearly along the axial direction of the tubular actuator 2, and the driver is a linear drive mechanism such as a linear motor. The straight knife is connected to the driver, and the driver can drive the straight knife to move linearly back and forth along the axial direction of the tubular actuator 2, and the straight knife removes the axillary tissue 5 by pushing and pulling.

[0055] In other embodiments, part of the driver may also be exposed outside the handle 1 , and the connecting portion of the actuator 2 is connected to the part of the driver exposed outside the handle 1 .

[0056] In this embodiment, the connection portion of the actuator 2 and the driver may be detachably connected, so that different actuators 2 can be replaced for surgery, and the actuator 2 can be disassembled for disinfection and maintenance.

[0057] The pressing piece 3 can be a rod-shaped structure, one end (front end) of the pressing piece 3 is a pressing portion 31, and the pressing portion 31 is a structure that radially protrudes from the pressing piece 3. The pressing portion 31 can be a spherical structure such as a ball, and the other end (rear end) of the pressing piece 3 is a connecting portion. The connecting portion of the pressing piece 3 is rotatably connected to the handle 1, and the pressing portion 31 of the pressing piece 3 is aligned with the actuator 21 of the actuator 2. The pressing portion 31 of the pressing piece 3 can be close to the incision 211 of the actuator 2 of the actuator 2 to form a pressing and clamping state. The pressing and clamping state is used to clamp the axillary tissue 5 to be surgically removed. Specifically, the pressing portion 31 squeezes the axillary tissue 5 from the outside of the axillary tissue 5 into the incision 211, and the pressing portion 31 of the pressing piece 3 can be away from the incision 211 of the actuator 2 to form an open state.

[0058] One end (front end) of the handle 4 is rotatably connected to the handle 1, and the other end (rear end) of the handle 4 forms a suspended free part. The handle 4 is linked with the pressing member 3. The handle 4 and the pressing member 3 can be located on the same side of the handle 1. The handle 4 can be linked with the pressing member 3 through a linkage structure, and the linkage structure can include a gear set or a multi-link structure. The doctor holds the handle 1 and controls the handle 4 to operate the opening and pressing of the pressing member 3.

[0059] In this embodiment, when the handle 4 is pressed down, the pressing portion 31 moves toward the direction close to the incision 211, and finally abuts against the incision 211 indirectly, thereby clamping the subcutaneous tissue and squeezing the axillary tissue 5 into the incision 211. After the handle 4 is released, the pressing portion 31 moves away from the incision 211 under the action of elastic force, and finally opens relative to the incision 211. In this state, the execution portion 21 can be inserted into the axillary tissue 5 or withdrawn from the axillary assembly.

[0060] In other embodiments, the handle 4 and the pressing piece 3 can be respectively located on both sides of the handle 1, and the handle 4 and the pressing piece 3 are fixedly connected, so that the axillary tissue resection device forms a scissor-like structure, and the handle 4 can also control the movement of the pressing piece 3 relative to the incision 211, that is, it can also press the axillary tissue 5 and release the pressing of the axillary tissue 5.

[0061] In this embodiment, the ratio of the diameter d1 of the incision 211 to the diameter d2 of the pressing portion 31 is limited to limit the thickness of the axillary tissue 5 squeezed into the incision 211, thereby enabling the cutter 22 to cut off a thinner axillary tissue 5 each time, thereby avoiding cutting off the transitional axillary tissue 5 and avoiding the axillary tissue 5 being squeezed transitionally to cause wrinkles and be cut by the cutter 22.

[0062] In this embodiment, the diameter d1 of the circular incision 211 and the diameter d2 of the spherical pressing portion 31 are set within a certain proportional range to control the depth L of the pressing portion 31 penetrating into the incision 211 when the pressing portion 31 and the incision 211 clamp the axillary tissue 5, so as to control the thickness of the axillary tissue 5 squeezed by the pressing portion 31 into the incision 211. Among them, the ratio of the diameter d2 of the pressing portion 31 to the diameter d1 of the incision 211 is 2.286:1-2.58:1. Under this ratio, the depth L of the pressing portion 31 invading the incision 211 can be controlled to be smaller. The pressing portion 31 and the incision 211 in this ratio range, the depth L of the pressing portion 31 invading the incision 211 is 0.2-0.5mm, so that the thickness of the part of the clamped and squeezed armpit component entering the incision 211 is 0.2-0.5mm. The squeezed thickness is small, and each time the clamping and cutting is performed, the armpit tissue 5 with a smaller thickness of 0.2-0.5mm can be cut off, which can avoid the one-time cutting of thicker armpit tissue 5, prevent excessive cutting, and prevent the armpit tissue 5 from being wrinkled and damaged due to excessive squeezing.

[0063] It should be noted that the depth L of the pressing portion 31 penetrating into the incision 211 is 0.2-0.5 mm, which refers to the case where the axillary tissue 5 is not clamped. Figure 2 As shown, when the pressing portion 31 directly contacts and clamps the incision 211, the penetration depth of the pressing portion 31. During the operation, since the pressing portion 31 can penetrate into the incision 211 to a depth L of 0.2-0.5 mm, when the pressing portion 31 clamps the axillary tissue 5, the tissue can be squeezed to a depth of the incision 211 that is equal to or approximately equal to the depth of the pressing portion 31 penetrating into the incision 211, that is, the thickness of the axillary tissue 5 squeezed into the incision 211 is 0.2-0.5 mm.

[0064] In this embodiment, the diameter d1 of the incision 211 can be within the range of 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 is 8±0.2 mm. When the incision 211 and the pressing portion 31 are within this range, when the pressing portion 31 and the execution portion 21 clamp the axillary tissue 5, the pressing portion 31 can squeeze the axillary tissue 5 with a thickness of 0.35±0.2 mm into the incision 211. The pressing portion 31 can squeeze the axillary tissue 5 of appropriate thickness into the incision 211, thereby achieving the resection of the axillary tissue 5 of appropriate thickness.

[0065] In a preferred embodiment, the ratio of the diameter d2 of the pressing portion 31 to the diameter d1 of the incision 211 is 2.242:1, wherein the diameter d2 of the pressing portion 31 is 8 mm, and the diameter d1 of the incision 211 is 3.3 mm. When the pressing portion 31 and the incision 211 of this ratio clamp the axillary tissue 5, the depth L of the axillary tissue 5 squeezed into the incision 211 is 0.35 mm, forming a more suitable invasion depth L. The cutter 22 can remove 0.35 mm thick axillary tissue 5 each time, and can perform high-precision removal multiple times to achieve accurate removal of the lesion without damaging other good axillary tissue 5.

[0066] In this embodiment, the diameter d3 of the actuator 2 can be in the range of 3-10 mm, preferably 6-10 mm, for example, the diameter d3 of the actuator 2 is 6 mm or 8 mm. The actuator 2 is a slender tubular structure, which is more conducive to being inserted into the axillary tissue 5, reducing insertion damage to the axillary tissue 5.

[0067] The axillary tissue resection device of this embodiment sets the incision 211 of the execution part 21 to be circular, sets the pressing part 31 to be spherical, and limits the ratio of the diameter d2 of the pressing part 31 to the diameter d1 of the incision 211. This makes it possible to limit the pressing part 31 and the incision 211 to squeeze the tissue, so that the thinner axillary tissue 5 can be squeezed into the inner side of the incision 211 in an arc shape, thereby achieving multiple ultra-thin resections of the axillary tissue 5, avoiding squeezing too much axillary tissue 5 into the incision 211, preventing the tissue from being squeezed into wrinkles, and preventing too much tissue from being removed at one time, thereby achieving more accurate and effective resection and avoiding harm to the patient.

[0068] In one embodiment, the incision 211 on the actuator 21 may also be an ellipse, the ellipse includes a maximum diameter and a minimum diameter that are perpendicular to each other, the maximum diameter direction of the ellipse is parallel to the axial direction of the actuator 2, and the minimum diameter direction of the ellipse is parallel to the radial direction of the actuator 2. The incision 211 set in this way can also achieve the removal of thinner axillary tissue 5.

[0069] Among them, the diameter d3 of the elliptical incision 211 is the minimum diameter of the incision 211, that is, when the minimum diameter of the incision 211 is 3.3±0.2mm, it can also be combined with the pressing part 31 with a diameter d2 of 8±0.2mm to squeeze the axillary tissue 5 with a thickness of 0.2-0.5mm into the elliptical incision 211, thereby realizing multiple ultra-thin resections of the axillary tissue 5.

[0070] In one embodiment, the pressing portion 31 may also be a hemispherical structure, with the spherical surface of the hemispherical structure facing the incision 211 , so that the spherical surface of the pressing portion 31 can clamp the axillary tissue 5 with the incision 211 .

[0071] Since the depth of the pressing portion 31 invading the incision 211 is less than the radius of the pressing portion 31 , the pressing portion 31 is set as a hemispherical structure, and the thinner axillary tissue 5 can also be squeezed into the incision 211 in an arc manner, thereby achieving multiple ultra-thin resections of the axillary tissue 5.

[0072] In one embodiment, an axillary tissue resection device is provided. The difference between this axillary tissue resection device and the above-mentioned axillary tissue resection device is that: in this embodiment, the depth of the pressing part 31 invading the incision 211 when the pressing part 31 and the execution part 21 are clamped is limited, so as to limit the thickness of the axillary tissue 5 squeezed into the incision 211 during the operation.

[0073] In this embodiment, the diameter d1 of the incision 211 may be in the range of 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 may be 8±0.2 mm, so as to control the depth of the pressing portion 31 invading the incision 211 to be 0.2-0.5 mm.

[0074] In other embodiments, the diameter d1 of the incision 211 and the diameter d2 of the pressing portion 31 may also be other numerical ranges, as long as the depth of the pressing portion 31 invading the incision 211 is 0.2-0.5 mm. For example, the diameter d1 of the incision 211 is set to a range smaller than 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 is set to a range smaller than 8±0.2 mm; or, the diameter d1 of the incision 211 is set to a range larger than 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 is set to a range larger than 8±0.2 mm, which can also satisfy the control of the depth of the pressing portion 31 invading the incision 211 to be 0.2-0.5 mm. The pressing portion 31 and the incision 211 of smaller or larger sizes can meet the use needs of characteristic patients, such as when the patient's lesion is particularly large or particularly small.

[0075] In this embodiment, by limiting the depth of the pressing portion 31 invading the incision 211 when the pressing portion 31 and the execution portion 21 are clamped, the thickness of the axillary tissue 5 squeezed into the incision 211 is limited, so that the cutter 22 can cut off a thinner axillary tissue 5 each time, avoiding the cutting of the transitional axillary tissue 5, and avoiding the axillary tissue 5 being squeezed transitionally to cause wrinkles and be cut by the cutter 22.

[0076] In one embodiment, an axillary tissue resection device is provided. The difference between this axillary tissue resection device and the above-mentioned axillary tissue resection device is that this embodiment limits the diameter d1 of the incision 211 and the diameter d2 of the pressing part 31 to have size values ​​to limit the thickness of the axillary tissue 5 squeezed into the incision 211 during surgery.

[0077] In this embodiment, the diameter d1 of the incision 211 may be in the range of 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 may be 8±0.2 mm, so as to control the depth of the pressing portion 31 invading the incision 211 to be 0.2-0.5 mm.

[0078] In other embodiments, the diameter d1 of the incision 211 and the diameter d2 of the pressing portion 31 may also be other numerical ranges, as long as the depth of the pressing portion 31 invading the incision 211 is 0.2-0.5 mm. For example, the diameter d1 of the incision 211 is set to a range smaller than 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 is set to a range smaller than 8±0.2 mm; or, the diameter d1 of the incision 211 is set to a range larger than 3.3±0.2 mm, and the diameter d2 of the pressing portion 31 is set to a range larger than 8±0.2 mm, which can also satisfy the control of the depth of the pressing portion 31 invading the incision 211 to be 0.2-0.5 mm. The pressing portion 31 and the incision 211 of smaller or larger sizes can meet the use needs of characteristic patients, such as when the patient's lesion is particularly large or particularly small.

[0079] In this embodiment, by limiting the size values ​​of the diameter d1 of the incision 211 and the diameter d2 of the pressing portion 31, the thickness of the axillary tissue 5 squeezed into the incision 211 is limited, so that the cutter 22 can cut a thinner axillary tissue 5 each time, avoid cutting the transitional axillary tissue 5, and avoid the axillary tissue 5 being squeezed transitionally to cause wrinkles and be cut by the cutter 22.

[0080] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
