[0026] See Figure 7 ,like Figure 7 As shown, in some embodiments, the frame 11 is in the shape of a shell, and the transmission assembly 14 is disposed in the shell cavity of the frame 11 ; the puncture frame 1 further includes a cover 16 that cooperates with the open surface of the frame 11 .

[0027] In this embodiment, the frame 11 is in the shape of a shell, which is convenient for accommodating the transmission assembly 14 and related functional modules, making the structure of the puncture frame 1 compact, reducing the volume of the puncture frame 1, saving material resources, and reducing the cost of the puncture frame 1; the puncture frame 1 also includes a cover 16 that cooperates with the open surface of the frame 11 to keep the puncture frame 1 closed. When puncturing, it can prevent tissue fluid and other liquids from entering the shell of the frame 11 and contacting the transmission assembly 14 to a certain extent, causing transmission failure of the transmission assembly 14; at the same time, it can prevent the external structure from affecting the movement of the transmission assembly 14, causing errors in the position of the slider 12 driven by the transmission assembly 14; when the frame 11 has a support column and other structures arranged along the relative direction of the cover 16 and the frame 11, a structure that cooperates with the support column structure can also be provided at the relative position of the cover 16. When the cover 16 cooperates with the frame 11, the support column and the structure cooperating with the support column also cooperate with each other, and the cover 16 and the frame 11 are used to enhance the support of the support column.

[0028] In some embodiments, a positioning shaft 113 is provided on the frame 11, and a positioning column 161 that cooperates with the positioning shaft 113 is provided on the cover 16. When the frame 11 and the cover 16 are closed, the positioning shaft 113 cooperates with the positioning column 161 to ensure that the frame 11 and the cover 16 are accurately matched; the frame 11 and the cover 16 are firmly closed by a snap or locking device. When there is a problem with the internal transmission component 14 or the connection between the transmission component 14 and the first manual operating member 13, or the fixation and sliding of the slider 12, they can be disassembled for certain processing; or, the frame 11 and the cover 16 are completely fixed by welding or bonding.

[0029] In some embodiments, the slider 12 is provided with a first guide protrusion 124 and a second guide protrusion 125, the first guide protrusion 124 is slidably set with the frame 11, and the second guide protrusion 125 is slidably set with the cover body 16; the first guide protrusion 124 and the second guide protrusion 125 are parallel to each other and are coordinated with the frame body 11 and the cover body 16 to guide the slider 12 along the lateral direction of the frame body 11.

[0030] In this embodiment, the frame 11 and the cover 16 of the puncture frame 1 sandwich the slider 12 in the middle, and a first guide protrusion 124 is provided on the slider 12 at a position that cooperates with the frame 11, and a second guide protrusion 125 is provided on the slider 12 at a position that cooperates with the cover 16. The first guide protrusion 124 and the second guide protrusion 125 guide the slider 12 along the transverse direction of the frame 11, so that the slider 12 slides relative to the frame 11 and the cover 16 along the transverse direction of the frame 11. At the same time, the frame 11 and the cover 16 support the slider 12 through the first guide protrusion 124 and the second guide protrusion 125 to prevent the slider 12 from falling from the middle of the frame 11 and the cover 16.

[0031] In some embodiments, the transmission assembly 14 includes a driving wheel 141, a driven wheel 142 and a synchronous belt 143 wrapped around the driving wheel 141 and the driven wheel 142; the driving wheel 141 is fixedly connected to the first manual operating member 13, and the first manual operating member 13 drives the driving wheel 141 to rotate relative to the frame 11; the driving wheel 141 uses the synchronous belt 143 to drive the driven wheel 142 to rotate synchronously with the driving wheel 141; the slider 12 is fixed to the linear motion segment of the synchronous belt 143, so that the synchronous belt 143 drives the slider 12 to move laterally along the frame 11.

[0032] In this embodiment, the driving wheel 141 is fixedly connected to the first manual operating member 13. At the same time, when the first manual operating member 13 is rotated, the driving wheel 141 can be driven to rotate synchronously with the frame 11. The driving wheel 141 drives the driven wheel 142 to rotate synchronously with the driving wheel 141 and the first manual operating member 13 through the synchronous belt 143; the slider 12 is fixed to the linear motion segment of the synchronous belt 143 to avoid uneven movement of the curved segment of the synchronous belt 143, which leads to uneven lateral movement of the slider 12, so that the actual displacement of the slider 12 does not correspond to the displacement indicated by the scale on the frame 11, resulting in puncture position error; at the same time, the puncture guide hole 122 of the slider 12 is not blocked by the frame 11, and the puncture operation can be performed through the puncture guide hole 122.

[0033] In some embodiments, grooves are provided on the outer circumference of the driving wheel 141 and the driven wheel 142, and the inner side surface of the synchronous belt 143 fits into the grooves of the driving wheel 141 and the driven wheel 142 to increase the friction between the synchronous belt 143 and the driving wheel 141 and the driven wheel 142, so that the driving wheel 141 can drive the driven wheel 142 to move without slipping through the synchronous belt 143.

[0034] In some embodiments, the first manual operating member 13 is arranged outside the shell of the frame 11, and a column is provided on the side of the first manual operating member 13 close to the frame 11, and a center hole is provided on the driving wheel 141 of the transmission assembly 14; the driving wheel 141 is arranged inside the frame 11, and a shell hole is provided on the frame 11 to connect the column and the center hole of the driving wheel 141; the column cooperates with the center hole of the driving wheel 141 through the shell hole, so that the first manual operating member 13 drives the driving wheel 141 and the synchronous belt 143 and the driven wheel 142 to move.

[0035] In some embodiments, the puncture frame 1 also includes a first guide wheel 17 and a second guide wheel 18, the first guide wheel 17 is arranged on the frame body 11 close to the driving wheel 141, and the second guide wheel 18 is arranged on the frame body 11 close to the driven wheel 142; the lower belt segment of the synchronous belt 143 is wound around the first guide wheel 17 and the second guide wheel 18, and / or the upper belt segment of the synchronous belt 143 is wound around the first guide wheel 17 and the second guide wheel 18; the distance between the lower belt segment and the upper belt segment between the driving wheel 141 and the driven wheel 142 is smaller than the radius of the driving wheel 141; the slider 12 is fixed to the linear motion segment of the upper belt segment or the lower belt segment.

[0036] In this embodiment, the lower belt segment of the synchronous belt 143 is wound around the first guide wheel 17 and the second guide wheel 18 and / or the upper belt segment of the synchronous belt 143 is wound around the first guide wheel 17 and the second guide wheel 18. On the one hand, the tension of the synchronous belt 143 can be increased, so that the synchronous belt 143 is tightened, especially the straight section of the synchronous belt 143 is tightened, so that the slider 12 moves evenly on the straight section of the synchronous belt 143. On the other hand, by winding the synchronous belt 143 around the first guide wheel 17 and the second guide wheel 18, the space utilization rate in the frame 11 can be improved, the volume of the puncture frame 1 can be reduced to a certain extent, the structure is stable, and it is convenient to slide While fixing the block 12 to the synchronous belt 143, it is ensured that the puncture guide hole 122 of the slider 12 is not blocked by the frame 11, and a stable puncture operation can be performed through the puncture guide hole 122; at the same time, by winding the synchronous belt 143, after the slider 12 is fixed on the synchronous belt 143, the slider 12 can slide flexibly relative to the guide rod 15; after the synchronous belt 143 is wound on the first guide wheel 17 and the second guide wheel 18, the distance between the lower belt segment and the upper belt segment on the synchronous belt 143 between the driving wheel 141 and the driven wheel 142 is smaller than the radius of the driving wheel 141, and the lower belt segment and the upper belt segment do not contact each other to avoid friction.

[0037] In some embodiments, the first guide wheel 17 and the second guide wheel 18 can be set on the positioning shaft 113, so that the first guide wheel 17 and the second guide wheel 18 can rotate relative to the positioning shaft 113; after the cover body 16 is matched with the frame body 11, the positioning column 161 on the cover body 16 is matched with the positioning shaft 113 to support the first guide wheel 17 and the second guide wheel 18, so as to avoid the first guide wheel 17 and the second guide wheel 18 from reacting the tensioning force of the synchronous belt 143 to the first guide wheel 17 and the second guide wheel 18, causing the rotation axis of the first guide wheel 17 and the second guide wheel 18 to tilt, thereby causing the movement of the driving wheel 141, the driven wheel 142 and the synchronous belt 143 to be deflected or erroneous.

[0038] In some embodiments, the synchronous belt 143 can be replaced by a transmission rope, while ensuring that it can be wound around the driving wheel 141 and the driven wheel 142, and after being wound around the first guide wheel 17 and the second guide wheel 18, it can evenly transmit power between the driving wheel 141 and the driven wheel 142 and drive the slider 12 to move evenly. Using a transmission rope instead of the synchronous belt 143 can further simplify the structure of the puncture frame 1 and reduce the cost of the puncture frame 1, so that the puncture frame 1 can be disposable, avoiding cross infection caused by repeated clinical use.

[0041] In some embodiments, a scale line can be arranged on the feeding structure body or the feeding telescopic shaft to accurately indicate the position of the feeding direction of the puncture device 100, so as to improve the position control accuracy of the puncture device 100 in the feeding direction.

[0042] In some embodiments, the feeding transmission assembly can adopt a screw nut transmission, so that the position control of the feeding direction of the puncture device 100 can be more accurate.
