[0033] In the embodiment, the frame body 11 and the cover body 16 of the puncture frame 1 sandwich the sliding block 12, the sliding block 12 is provided with a first guide protrusion 124 at a position matched with the frame body 11, and the sliding block 12 is provided with a second guide protrusion 125 at a position matched with the cover body 16, the first guide protrusion 124 and the second guide protrusion 125 guide the sliding block 12 in the transverse direction of the frame body 11, so that the sliding block 12 slides in the transverse direction of the frame body 11 relative to the frame body 11 and the cover body 16, and meanwhile the frame body 11 and the cover body 16 support the sliding block 12 through the first guide protrusion 124 and the second guide protrusion 125, so as to avoid the sliding block 12 from falling off from the middle of the frame body 11 and the cover body 16.

[0035] In the embodiment, the driving wheel 141 is fixedly connected with the first manual operating member 13, and when the first manual operating member 13 is rotated, the driving wheel 141 is driven to rotate synchronously relative to the frame body 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 by means of the synchronous belt 143, and the sliding block 12 is fixed to a straight motion segment of the synchronous belt 143, so as to avoid the uneven motion of the curved segment of the synchronous belt 143 from causing the uneven transverse motion of the sliding block 12, and thus the actual displacement of the sliding block 12 does not correspond to the displacement indicated by the scale on the frame body 11, resulting in puncture position error; meanwhile, the puncture guide hole 122 of the sliding block 12 is not blocked by the frame body 11, and the puncture operation can be performed through the puncture guide hole 122.

[0036] In some embodiments, recesses are arranged on the outer circumferential surfaces of the driving wheel 141 and the driven wheel 142, and the inner side surface of the synchronous belt 143 is matched with the recesses of the driving wheel 141 and the driven wheel 142, so as to increase the friction between the synchronous belt 143 and the driving wheel 141 and the driven wheel 142, and enable the driving wheel 141 to drive the driven wheel 142 to move without sliding through the synchronous belt 143.

[0037] In some embodiments, the first manual operating member 13 is arranged outside the housing of the frame body 11, and a column is arranged on one side of the first manual operating member 13 close to the frame body 11, and a central hole is arranged on the driving wheel 141 of the transmission assembly 14; the driving wheel 141 is arranged in the frame body 11, and a housing hole is arranged on the frame body 11 to connect the column and the central hole of the driving wheel 141; the column is matched with the central hole of the driving wheel 141 through the housing hole, so that the first manual operating member 13 drives the driving wheel 141, the synchronous belt 143 and the driven wheel 142 to move.

[0038] In some embodiments, the puncture frame 1 further comprises 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 arranged around the first guide wheel 17 and the second guide wheel 18, and / or the upper belt segment of the synchronous belt 143 is arranged 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 less than the radius of the driving wheel 141; the sliding block 12 is fixed to the straight line movement segment of the upper belt segment or the lower belt segment.

[0039] In this embodiment, the lower belt segment of the synchronous belt 143 is arranged around the first guide wheel 17 and the second guide wheel 18 and / or the upper belt segment of the synchronous belt 143 is arranged around the first guide wheel 17 and the second guide wheel 18, which can increase the tension of the synchronous belt 143, make the synchronous belt 143 tight, especially the straight line segment of the synchronous belt 143, so that the sliding block 12 moves uniformly on the straight line segment of the synchronous belt 143, and on the other hand, by arranging the synchronous belt 143 around the first guide wheel 17 and the second guide wheel 18, the space utilization in the frame body 11 can be improved, the volume of the puncture frame 1 can be reduced to a certain extent and the structure is stable, which facilitates the fixation of the sliding block 12 and the synchronous belt 143 while ensuring that the puncture guide hole 122 of the sliding block 12 is not blocked by the frame body 11, and stable puncture operation can be performed through the puncture guide hole 122; at the same time, after the synchronous belt 143 is arranged around the first guide wheel 17 and the second guide wheel 18, the sliding block 12 can slide flexibly relative to the guide rod 15 after the sliding block 12 is fixed on the synchronous belt 143; after the synchronous belt 143 is arranged around the first guide wheel 17 and the second guide wheel 18, the distance between the lower belt segment and the upper belt segment of the synchronous belt 143 between the driving wheel 141 and the driven wheel 142 is less 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.

[0041] In some embodiments, the synchronous belt 143 can be replaced by a transmission rope, and the transmission rope can be arranged around the driving wheel 141 and the driven wheel 142 and can uniformly drive the driving wheel 141 and the driven wheel 142 and the sliding block 12 after being arranged around the first guide wheel 17 and the second guide wheel 18. The use of the transmission rope instead of the synchronous belt 143 can further simplify the structure of the puncture frame 1, reduce the cost of the puncture frame 1, and enable the puncture frame 1 to be used once, thereby avoiding cross infection caused by repeated use in a clinic.

[0042] In some embodiments, the frame body 11 is further provided with an elastic buckle structure or a clamping groove structure matched with the elastic buckle structure, so that the puncture frame 1 can be detachably connected to a puncture device, and the puncture frame 1 can be conveniently detached from the puncture device after being used once, thereby avoiding cross infection caused by repeated use in a clinic.
