[0070] It should be noted that like numbers and letters refer to like items throughout the drawings, and that, once an item is defined in one drawing, it should not require further discussion in subsequent drawings.

[0071] According to a first aspect of the present application, a rotary cutting handle is provided. Referring to Figures 1-16 As shown, the rotary cutting handle comprises a driving device 1, a rotary cutting device 2 and a collecting device 3.

[0072] The rotary cutting device 2 is connected with the driving device 1. The rotary cutting device 2 comprises an outer sleeve assembly 23 and an inner sleeve 24, the inner sleeve 24 is arranged in the outer sleeve assembly 23, and a sampling groove 231 is formed on the outer sleeve assembly 23.

[0073] The driving device 1 drives the inner sleeve 24 to move along the axial direction of the outer sleeve assembly 23 and rotate.

[0074] The collecting device 3 is detachably connected with the rotary cutting device 2; the collecting device 3 comprises a collecting part 31, which is communicated with the inner sleeve 24. The collecting part 31 comprises a collecting basket 310 and a carrier part 312, and the driving device 1 drives the carrier part 312 to overturn in the collecting basket 310.

[0075] In other words, the rotary cutting handle mainly comprises the driving device 1, the rotary cutting device 2 and the collecting device 3.

[0076] In this embodiment, the driving device 1 is connected with the rotary cutting device 2. For example, the driving device 1 and the rotary cutting device 2 are fixedly connected, or the driving device 1 and the rotary cutting device 2 are detachably connected. When the driving device 1 and the rotary cutting device 2 are detachably connected, it is convenient for the user to replace the driving device of the rotary cutting handle.

[0077] For example, the driving device 1 and the rotary cutting device 2 are connected through the snap-fit mode. The driving device 1 is provided with a locking ring part, and the rotary cutting device 2 is provided with a locking part. The driving device 1 and the rotary cutting device 2 are connected through the cooperation of the locking ring part and the locking part. Alternatively, the driving device 1 and the rotary cutting device 2 are connected through the magnetic adsorption mode or the like. For example, the driving device 1 is provided with a magnetic part, and the rotary cutting device 2 is provided with a magnetic adsorption part. The driving device 1 and the rotary cutting device 2 are connected through the cooperation of the magnetic part and the magnetic adsorption part. Figure 1 As shown in the figure, the rotary cutting device 2 is formed with a receiving space for accommodating the driving device 1, and the driving device 1 is installed in the receiving space and connected with the rotary cutting device 2 through the snap-fit cooperation. The connection mode of the driving device 1 and the rotary cutting device 2 in this embodiment is not limited, as long as the detachable connection of the driving device 1 and the rotary cutting device 2 can be realized.

[0078] In this embodiment, the rotary cutting device 2 and the collecting device 3 are connected. For example, the collecting device 3 and the rotary cutting device 2 can be connected in a fixed mode or in a detachable mode. When the collecting device 3 and the rotary cutting device 2 are connected in a detachable mode, the rotary cutting device 2 and the collecting device 3 are connected through the snap-fit mode; or the rotary cutting device 2 is provided with a recess part, and the collecting device 3 is provided with a protrusion part. The rotary cutting device 2 and the collecting device 3 are connected through the cooperation of the recess part and the protrusion part; or the rotary cutting device 2 and the collecting device 3 are connected through the magnetic adsorption mode or the like.

[0079] The connection mode of the rotary cutting device 2 and the collecting device 3 in this embodiment is not limited, as long as the detachable connection of the rotary cutting device 2 and the collecting device 3 can be realized.

[0080] In this embodiment, the rotary cutting device 2 comprises an outer sleeve assembly 23. The outer sleeve assembly 23 is provided with a sampling groove 231 for adsorbing the diseased tissue. In specific use, the outer sleeve assembly 23 comprises a puncture needle 232. When the puncture needle 232 is rotated by the medical staff, the outer sleeve assembly is operated (for example, the user can rotate the rotary cutting handle) through the B-ultrasound observation, so as to ensure that the sampling groove 231 is located below the diseased tissue to be cut.

[0081] In this embodiment, the rotary cutting device 2 includes an inner sleeve 24. The inner sleeve 24 is located inside the outer sleeve assembly 23. The inner sleeve 24 can move back and forth and rotate to cut along the axial direction of the outer sleeve assembly 23. Specifically, the inner sleeve 24 is located inside the outer sleeve assembly 23 and is a hollow tubular structure. The inner cavity of the inner sleeve 24 forms an airway for extracting lesion tissue. The end of the inner sleeve 24 near the sampling groove 231 forms a blade. The inner cavity of the inner sleeve 24 is connected to the collecting device 3. Under negative pressure, the lesion component cut by the inner sleeve 24 can be extracted from the inner cavity into the collecting device 3.

[0082] In this embodiment, the drive device 1 has two functions. First, the drive device 1 drives the inner sleeve 24 to move back and forth and rotate for cutting along the axial direction of the outer sleeve assembly 23. Second, the drive device 1 drives the platform portion 312 to flip.

[0083] For example, the inner sleeve 24 moves and rotates towards the sampling groove 231, causing the opening of the sampling groove 231 to gradually decrease. At this point, the inner sleeve 24 can cut the diseased tissue. After the inner sleeve 24 completes the cutting of the diseased tissue, the diseased tissue located in the sampling groove 231 enters the stage section 312 through the inner sleeve 24. Under negative pressure, the diseased tissue located in the sampling groove 231 enters the stage section 312 through the inner sleeve 24. After the medical staff completes the initial observation of the diseased tissue, the diseased tissue located in the stage section 312 is flipped into the collection basket 310.

[0084] This embodiment provides a rotary cutting handle. The rotary cutting handle includes a drive device 1, a rotary cutting device 2, and a collection device 3. The drive device 1 can drive the inner sleeve 24 on the rotary cutting device 2 to move and cut, thereby cutting the diseased tissue; the drive device 1 can also drive the collection part 31 of the collection device 3 to flip. The diseased tissue cut off by the rotary cutting handle enters the stage part 312 along the inner sleeve 24, where medical personnel can observe and touch the diseased tissue located on the stage part 312; after the medical personnel have completed the initial observation of the diseased tissue, the drive device 1 then drives the stage part 312 to flip, causing the diseased tissue to fall into the collection basket 310, thereby collecting the diseased tissue. The rotary cutting handle of this invention facilitates the observation of diseased tissue.

[0085] In one embodiment, refer to Figure 6 As shown, the collection device 3 includes a transmission part 32, which is connected to the collection part 31. The transmission part 32 and the collection part 31 can be fixedly connected, or they can be detachably connected. For example, the transmission part 32 and the collection basket 310 can be detachably connected via a snap-fit ​​mechanism. This embodiment does not limit the connection method between the transmission part 32 and the collection basket 310.

[0086] In this embodiment, the transmission channel 322 is arranged on the transmission part 32, one end of the transmission channel 322 is communicated with the carrier part 312, and the other end of the transmission channel 322 is communicated with the inner sleeve 24.

[0087] For example, the collecting device 3 comprises the collecting part 31 and the transmission part 32. The transmission part 32 is arranged with the transmission channel 322, and the transmission channel 322 is communicated with the inner sleeve 24. Therefore, under the action of negative pressure, the lesion tissue in the sampling groove 231 enters the carrier part 312 through the inner sleeve 24 and the transmission channel 322. After the lesion tissue in the sampling groove 231 enters the collecting part 31 under the action of negative pressure, the driving device 1 drives the carrier part 312 to overturn.

[0088] In a specific embodiment, referring to Figure 6 The transmission part 32 is arranged with a connecting plate, and the collecting basket 310 is arranged with a connecting part matched with the connecting plate at the end close to the transmission part 32. When the connecting plate and the connecting part are connected, the connecting plate and the connecting part can seal the collecting basket 310. For example, the material of the connecting plate is rubber material or the like.

[0089] The connecting plate is arranged with a mounting hole, and the transmission channel 322 is fixed on the mounting hole to transport the lesion tissue by negative pressure.

[0090] In an embodiment, the carrier part 312 comprises a bearing platform, and a plurality of through holes 3121 are arranged on the bearing platform.

[0091] Referring to Figure 4 and Figure 6 Specifically, the carrier part 312 comprises a bearing platform. Under the action of negative pressure, the lesion tissue in the sampling groove 231 is extracted to the bearing platform. After the lesion tissue is extracted to the bearing platform, the blood stains on the lesion tissue can drop through the plurality of through holes 3121, which is convenient for medical staff to observe the lesion tissue. For example, the plurality of through holes 3121 are arranged in an array on the bearing platform.

[0092] In an embodiment, referring to Figure 5 and Figure 6 The collecting basket 310 is arranged with a window 313.

[0093] Specifically, under the action of negative pressure, the lesion tissue in the sampling groove 231 enters the carrier part 312 through the inner sleeve 24 and the transmission channel 322. The carrier part 312 is rotatably arranged on the collecting basket 310. The window 313 is arranged on the collecting basket 310 and corresponds to the carrier part 312, which is convenient for medical staff to observe and touch the lesion tissue through the window 313.

[0094] In one embodiment, referring to Figure 6 The collecting basket 310 is provided with a cover plate 314, which is detachably or relatively movably opened on the collecting basket 310.

[0095] Specifically, under the action of negative pressure, the lesion tissue in the sampling groove 231 enters the loading platform 312 through the inner sleeve 24 and the transmission channel 322. The loading platform 312 is reversibly provided on the collecting basket 310. The cover plate 314 is provided on the collecting basket 310. The user detaches the cover plate 314 or moves the position of the cover plate 314 to facilitate the user to observe and touch the lesion tissue on the loading platform 312.

[0096] In one specific embodiment, the cover plate 314 is provided with a handle 315, which facilitates the user to operate the cover plate 314 through the handle 315.

[0097] In one specific embodiment, the window 313 can be an opening structure, that is, the window 313 is an opening structure provided on the collecting basket 310; or the window 313 includes an opening structure and a covering film, and the covering film is provided on the opening structure. The covering film is a transparent film. When the window 313 is an opening structure, the cover plate 314 can be provided on the window 313.

[0098] In one specific embodiment, referring to Figure 17 The collecting basket 310 is provided with a fixed ring near the end (the end is close to the base 311 of the collecting part 31) region, and the handle 315 can penetrate the fixed hole to store the handle 315 without the need of the medical staff to use the handle 315.

[0099] In one specific embodiment, the end of the handle 315 away from the end of the collecting basket 310 is a pointed end, and after the handle 315 penetrates the fixed hole, the pointed end of the handle 315 can be resisted on the base 311. At this time, the handle 315 is equivalent to a blocking wall, which can avoid the disengagement of the light source device 33 installed on the base 311 from the base 311.

[0100] In one embodiment, referring to Figure 3 、 Figure 5 、 Figure 7 、 Figure 10 、 Figure 11 and Figure 13 The driving device 1 includes a first motor 13. The inner sleeve 24 is provided with a first transmission module 25, and the first motor 13 is gear engaged with the first transmission module 25.

[0101] The first transmission module 25 comprises a first sleeve 251 and a second sleeve 252. The first sleeve 251 is sleeved outside the inner sleeve 24. The second sleeve 252 is sleeved outside the first sleeve 251. The first sleeve 251 and the second sleeve 252 are screw fitted.

[0102] Specifically, the rotation of the inner sleeve 24 is realized by the gear engagement of the first motor 13 and the first transmission module 25. The movement of the inner sleeve 24 is realized by the screw fitting of the first sleeve 251 and the second sleeve 252.

[0103] In a specific embodiment, the first motor 13 is provided with a first gear 131. The first transmission module 25 comprises a first sleeve 251 sleeved outside the inner sleeve 24. The first sleeve 251 is sleeved with a second gear 253. The first gear 131 and the second gear 253 are engaged. For example, the first motor 13 is provided with the first gear 131. The first motor 13 can drive the first gear 131 to rotate clockwise or counterclockwise. For example, the first gear 131 rotates clockwise. The inner sleeve 24 moves and rotates towards the sampling groove 231. The first gear 131 rotates counterclockwise. The inner sleeve 24 moves and rotates away from the sampling groove 231.

[0104] In a specific embodiment, the first transmission module 25 comprises a first sleeve 251, a second sleeve 252 and a second gear 253. The first sleeve 251 is sleeved outside the inner sleeve 24 and tightly fitted with the inner sleeve 24. The second gear 253 is sleeved on the outer periphery of the first sleeve 251 and tightly fitted with the first sleeve 251. The first gear 131 and the second gear 253 are engaged. When the first motor 13 drives the first gear 131 to rotate, the first gear 131 and the second gear 253 are engaged. The first gear 131 drives the second gear 253 to rotate. The second gear 253 drives the first sleeve 251 and the inner sleeve 24 to rotate.

[0105] A first fitting surface is formed on the outer surface of the first sleeve 251. The second sleeve 252 is sleeved on the first fitting surface. A second fitting surface is formed on the inner surface of the second sleeve 252. The first fitting surface and the second fitting surface are screw fitted. Specifically, when the first gear 131 drives the inner sleeve 24 to rotate, the first sleeve 251 also rotates together. Due to the screw fitting of the first fitting surface and the second fitting surface, the first sleeve 251 moves axially forward and backward while rotating, thereby driving the inner sleeve 24 to move forward and backward and rotate cut in the outer sleeve assembly 23.

[0106] In a specific embodiment, the first fitting surface is a threaded surface with a predetermined length. The second fitting surface is a threaded surface with a predetermined length.

[0107] In an alternative embodiment, the first matching surface is directly formed on the outer circumferential surface of the inner sleeve 24, and the first gear is tightly matched with the inner sleeve 24. The sleeve is sleeved on the inner sleeve 24, and the second matching surface is formed on the inner circumferential surface of the sleeve. The first matching surface and the second matching surface are screw matched.

[0108] The first transmission module 25 of the embodiment has a simple structure, and through the cooperation of the first gear 131 on the first motor 13 and the first transmission module 25, the forward and backward movement and rotation of the inner sleeve 24 can be realized.

[0109] In an embodiment, as shown in Figure 4 , Figure 5 and Figure 6 , the driving device 1 comprises a second motor 14. The collecting device 3 comprises a transmission part 32. The transmission part 32 is provided with a second transmission module 321, and the collecting part 31 is connected with the second transmission module 321. The second motor 14 is gear engaged with the second transmission module 321.

[0110] Specifically, through the transmission between the second motor 14 and the second transmission module 321, the turn-over of the platform part 312 in the collecting basket 310 can be driven.

[0111] In a specific embodiment, as shown in Figure 4 , Figure 5 and Figure 6 , the second transmission module 321 comprises a connecting shaft 3212 and a third gear 3211 provided on the connecting shaft 3212, and the platform part 312 is fixedly connected with the connecting shaft 3212. The second motor 14 is provided with a fourth gear 141, and the third gear 3211 is gear engaged with the fourth gear 141.

[0112] The fourth gear 141 is provided on the second motor 14, and the second motor 14 drives the fourth gear 141 to rotate. For example, the second motor 14 drives the fourth gear 141 to rotate clockwise. Or the second motor 14 drives the fourth gear 141 to rotate counterclockwise. Specifically, under the action of negative pressure, the cut-off lesion tissue enters the platform part 312. At this time, the fourth gear 141 is driven to rotate clockwise, and the platform part 312 is turned over to turn over the lesion tissue on the platform part 312 and drop into the collecting basket 310.

Figures 7-10 ​​​As shown, if the first gear 131 continues to be driven, the first matching surface and the second matching surface disengage, at which time the inner sleeve 24 will not continue to move forward.

[0156] In one embodiment, referring to Figures 7-10 As shown, the first limiting module 241 includes a first stop portion 2412 and a first elastic portion 2411. The first stop portion 2412 is fixedly arranged and sleeved outside the inner sleeve 24. The inner sleeve 24 moves towards the sampling groove 231. The first elastic portion 2411 is in a compressed state and abuts against the first stop portion 2412.

[0157] Specifically, referring to Figure 7 and Figure 9 As shown, the first limiting module 241 includes a first elastic portion 2411 and a first stop portion 2412. The first stop portion 2412 is fixedly arranged. For example, the first stop portion 2412 is fixedly arranged in the housing of the rotary cutting device 2. For example, referring to Figure 5 As shown, the rotary cutting device 2 includes a first half housing 21 and a second half housing 22. The first half housing 21 and the second half housing 22 are connected by a connecting piece 27. For example, the connecting piece 27 can be a snap structure. The first half housing 21 and the second half housing 22 are snap-fitted to form a containing space for accommodating the inner sleeve 24 and the outer sleeve assembly.

In the process of the first sleeve 251 gradually moving towards the sampling groove 231, the first elastic portion 2411 is gradually compressed.

[0160] When the first sleeve 251 moves to a state of disengaging the second sleeve 252 (i.e., the first matching surface of the first sleeve 251 and the second matching surface of the second sleeve 252 disengage), the first elastic portion 2411 is compressed to abut against the first stop portion 2412. In one embodiment, the helical length of the first matching surface is smaller than the helical length of the second matching surface, and in the process of the movement of the first sleeve 251, the first matching surface can disengage from the second matching surface. In this embodiment, the first matching surface of the first sleeve 251 moves to the front of the second matching surface of the second sleeve 252, and the first sleeve 251 disengages from the second sleeve 252.

[0161] When the first fitting surface is disengaged from the second fitting surface during the movement of the first sleeve 251, the first gear 131 is driven to rotate in the opposite direction, and the inner sleeve 24 is moved away from the sampling groove 231, so that the first sleeve 251 and the second sleeve 252 are in a critical fitting state, facilitating the movement of the inner sleeve 24 away from the sampling groove 231 and rotation.

[0163] Specifically, the second limiting module 242 is arranged in the rotary cutting device 2 to define the second position of the movement of the inner sleeve 24 away from the sampling groove 231. When the inner sleeve 24 moves to the second position (the last end of the sampling groove 231, at which the sampling groove 231 is in a fully open state), referring to Figure 14 , the sampling groove 231 is not covered by the inner sleeve 24. If the first gear 131 is continuously driven, referring to Figures 13-16 , the first fitting surface is disengaged from the second fitting surface, and the inner sleeve 24 will not continue to move backward.

One end of the second elastic portion 2421 is fixed on the second stop portion 2422, and the other end of the second elastic portion 2421 is fixed on the first sleeve 251.

[0167] Under the cooperation of the first gear 131 and the first transmission module 25, the first sleeve 251 and the inner sleeve 24 move and rotate in the axial direction. In the process of the first sleeve 251 gradually moving away from the sampling groove 231, the second elastic portion 2421 is gradually compressed.

[0168] When the first sleeve 251 moves to a state of disengaging from the helical cooperation with the second sleeve 252 (i.e., the first cooperation surface of the first sleeve 251 and the second cooperation surface of the second sleeve 252 disengage), the second elastic portion 2421 is compressed to abut against the second stop portion 2422. Specifically, the helical length of the first cooperation surface is smaller than the helical length of the second cooperation surface, and in the process of the movement of the first sleeve 251, the first cooperation surface can disengage from the second cooperation surface.

[0171] After the rotary cutting handle is powered on, the rotary cutting handle first performs self-checking. Specifically, within a predetermined time t1, the inner sleeve 24 is driven to move and rotate at a predetermined speed to the direction closest to the sampling groove 231. When the predetermined time t1 is reached, it is determined that the inner sleeve 24 has moved to the front end of the sampling groove 231, and the predetermined time t1 is an empirical value. The position at this moment is taken as the zero point of counting. The opening degree of the sampling groove 231 corresponds to the length of the first cooperation surface of the first sleeve 251 in a one-to-one manner. The first motor 13 is driven, and the number of pulses of the rotation of the first gear 131 is recorded by the encoder. The user can control the start and stop of the first motor 13 through the number of pulses of the encoder, thereby realizing the control of the opening degree of the sampling groove 231.

At this time, the first elastic part triggers the pressure sensor arranged on the first stop part. When the system detects that the pressure sensor has the maximum pressure value, the system takes the position as the zero point, and clears the encoder count signal as the zero point.
