In the embodiment of the present application, the control device 60 determines whether there is first information in the real-time puncture image information sent by the camera module 50, where the first information is image information of the superficial tissue 200 of the biological tissue to be punctured, and when the control device 60 determines that the superficial tissue 200 is punctured, the control device controls the second driving mechanism 40 to stop the forward movement of the puncture needle 20, so as to prevent the puncture needle 20 from continuously puncturing the interior of the biological tissue, and prevent the puncture needle 20 from accidentally injuring the biological tissue in the patient's body.

It should be noted that, when the control device 60 confirms that the first information does not exist in the real-time puncture image information sent by the image pickup assembly 50, the image pickup assembly 50 is controlled to continue to shoot the puncture image information in real time, the second driving mechanism 40 drives the puncture needle 20 to move in the direction away from the second driving mechanism, and the first driving mechanism 30 drives the sheath 10 to move in the direction away from the second driving mechanism until the control device 60 confirms that the first information exists in the real-time puncture image information sent by the image pickup assembly 50.

In an embodiment of the present application, another puncturing method based on the puncture outfit provided in the above embodiments is provided, and a flow chart of the puncturing method is shown in fig. 13, and includes steps S201 to S206:

s201, starting the first driving mechanism, the second driving mechanism and the camera shooting assembly.

Alternatively, the control device 60 controls the activation of the first drive mechanism 30, the second drive mechanism 40, and the camera assembly 50 according to the operator's instructions. Alternatively, the operator may activate the first drive mechanism 30, the second drive mechanism 40, and the camera assembly 50 directly via buttons or the like.

S202, the first driving mechanism and the second driving mechanism are controlled to move towards the direction close to the biological tissue.

Alternatively, the control device 60 controls the operations of the first driving mechanism 30 and the second driving mechanism 40, so that the first driving mechanism 30 drives the sheath 10 to move in the direction close to the biological tissue, so that the second driving mechanism 40 drives the puncture needle 20 and the imaging assembly 50 to move in the direction close to the biological tissue, and at the same time, the imaging assembly 50 captures the puncture image information in real time.

And S203, confirming whether the first information exists in the real-time puncture image information sent by the camera assembly. If yes, executing S204; if not, the process returns to the step S202.

Alternatively, the control device 60 may confirm whether the first information exists according to the real-time puncture image information transmitted from the camera module 50. In the embodiment of the present application, the first information is image information of the superficial tissue 200 penetrating the pierced biological tissue.

And S204, controlling the second driving mechanism to stop the puncture needle from moving in the direction away from the second driving mechanism.

Alternatively, when the puncture instrument punctures the superficial tissue 200 of the biological tissue immediately after the start, the puncture needle 20 is exposed to the sheath tube 10, and the superficial tissue 200 can be punctured by the puncture needle 20. As shown in fig. 14, which is a schematic view of the puncture needle 20 of the puncture device penetrating the superficial tissue 200, when the control device 60 confirms the penetration of the superficial tissue 200, the second driving mechanism 40 is controlled to stop the puncture needle 20 from moving toward the biological tissue to be treated, so as to prevent the puncture needle 20 from continuing to penetrate into the biological tissue, and prevent the puncture needle 20 from accidentally injuring the biological tissue in the patient's body. As shown in fig. 15, a schematic view is shown in which the puncture needle 20 of the puncture instrument is moved backward relative to the sheath 10, thereby exposing the sheath 10 relative to the puncture needle 20 so that the puncture needle 20 cannot contact the inside of the biological tissue.

S205, the first driving mechanism is controlled to work continuously, so that the first driving mechanism drives the sheath to move relative to the puncture needle until the sheath moves to a set position in the biological tissue.

Alternatively, the control device 60 controls the first driving mechanism 30 to continue to operate, so that the first driving mechanism 30 drives the sheath 20 to move relative to the puncture needle 10 until the sheath 20 moves to a set position inside the biological tissue.

And S206, controlling the first driving mechanism to stop.

Alternatively, the control device 60 controls the first drive mechanism 30 to stop so that the sheath 10 stops at the set position of the pierced biological tissue as shown in fig. 16, thereby completing the piercing of the biological tissue.

In an embodiment of the present invention, in the step 102, if it is confirmed that the first information exists, the controlling the second driving mechanism to stop the movement of the puncture needle in the direction away from the second driving mechanism 40 includes: controlling the second driving mechanism 40 to stop working so that the puncture needle 20 stops moving; alternatively, the second drive mechanism 40 is controlled to rotate in the reverse direction so that the puncture needle 20 moves backward.

Alternatively, when the control device 60 confirms the penetration of the superficial tissue 200, the second driving mechanism 40 is controlled to stop operating, so that the puncture needle 20 stops moving, thereby preventing the puncture needle 20 from continuously puncturing the inside of the biological tissue, and avoiding the puncture needle 20 from accidentally injuring the biological tissue in the patient's body.

Optionally, when the control device 60 confirms that the superficial tissue 200 penetrates, the second driving mechanism 40 is controlled to rotate reversely, so that the puncture needle 20 moves backwards, that is, the puncture needle 20 is driven by the second driving mechanism 40 to move in a direction away from the biological tissue to be treated, thereby preventing the puncture needle 20 from continuously puncturing the interior of the biological tissue, and avoiding the puncture needle 20 from causing accidental injury to the biological tissue in the patient body.

In an embodiment of the present application, the step 102 further includes: confirming whether second information exists according to the real-time puncture image information sent by the camera assembly 50; if the presence of the second information is confirmed, the first driving mechanism 30 is controlled to stop the operation so that the sheath tube 10 stops at the set position of the pierced biological tissue.

In the embodiment of the present invention, the image capturing unit 50 keeps operating while the puncture needle 20 stops moving or the puncture needle 20 moves backward, the image capturing unit 50 transmits the captured real-time puncture image information to the control unit 60, and the control unit 60 determines whether the second information exists or not based on the real-time puncture image information transmitted by the image capturing unit 50. In the embodiment of the present application, the second information is image information of the sheath 10 fed to the set position of the punctured biological tissue.

The control device 60 confirms that the second information is present, that is, at this time, the sheath 10 has been fed to the set position of the punctured biological tissue, and the control device 60 controls the first driving mechanism 30 to stop the operation, so that the sheath 10 stops at the set position of the punctured biological tissue, and since the outer peripheral wall of the sheath 10 is provided with the thread, it is possible to ensure that the frictional force between the sheath 10 and the biological tissue satisfies the requirement, so that the sheath 10 is fixed at the set position of the biological tissue.
