This utility model relates to the field of medical devices, specifically to an endoscopic bidirectional grasping forceps, comprising a sleeve and a forceps body. A sliding plate is mounted on the inner wall of the sleeve via a sliding fit. An adjusting rod is mounted on the upper surface of the sliding plate. A superior rod is symmetrically mounted on the bottom of the sliding plate via a pin. A pin is mounted on the bottom of the superior rod, and the forceps body is mounted on the bottom of the pin. A first slider is symmetrically mounted on the upper surface of the sleeve. A superior seat is mounted on the upper surface of the first slider via a sliding fit. A first collar is symmetrically mounted on the upper surface of the superior seat. A first spring rod is mounted on the inner end of the first collar and is inserted into the outer wall of the adjusting rod. A limiting plate is arranged inside the superior seat, and a connecting rod is mounted on the upper surface of the limiting plate. This utility model employs a first spring rod structure to ensure that the forceps head of the forceps body is in a closed state, preventing accidental opening of the forceps head during object removal and thus avoiding surgical failure, thereby improving surgical safety.

The embodiment of the invention provides a driving method and device of medical equipment and a medical system. The method comprises the following steps: receiving a voice instruction from a sound pickup device; inputting the voice instruction into a deep learning neural network, and outputting a driving instruction for driving the medical equipment based on the deep learning neural network; and driving the action of the medical equipment according to the driving instruction. Therefore, through voice control based on AI / ML, driving of the medical equipment can be accurately realized without assistance of multiple persons, the labor cost can be reduced, the efficiency can be improved, and the risk of operation failure can be reduced.

The utility model discloses a drainage tube conveying device and endoscope equipment, and belongs to the technical field of medical instruments.In the drainage tube conveying device, an electrode assembly is connected to the far end of a catheter, and a drainage tube body is arranged on the periphery of the catheter in a relatively movable and sleeving mode; the electrode assembly can be switched between the unfolded state and the contracted state, so that the electrode assembly can establish a channel through target tissue in the unfolded state, and after the drainage tube body arranged on the periphery of the catheter in a sleeving mode is fed into the target tissue, the electrode assembly can be contracted into an inner cavity of the drainage tube body; and the drainage tube body is withdrawn through the inner cavity of the drainage tube body, so that the drainage tube body is left in the target tissue. The electrode and the drainage tube do not need to be operated in a split mode in a traditional operation, exchange of two instruments is avoided, and therefore the problems of tissue fluid leakage and positioning deviation caused by instrument exchange can be avoided, the risk of operation failure is remarkably reduced, and the safety and success rate of the operation are improved.

This invention provides a leaflet lengthening device, including a delivery catheter, a first clamping arm, a second clamping arm, an opening and closing rod, and a locking assembly. The first clamping arm is fixed to the distal end of the delivery catheter, and the second clamping arm is rotatably connected to the proximal end of the first clamping arm. The opening and closing rod is connected to the proximal end of the second clamping arm and is used to open or close the second clamping arm. The locking assembly includes a blocking member and a push rod connected to the blocking member. The push rod is used to drive the blocking member to move to prevent the second clamping arm from opening. The leaflet lengthening device of this invention, by setting the opening and closing rod and the locking assembly, enables the push rod to drive the blocking member to move to prevent the second clamping arm from opening, thereby solving the technical problem of the second clamping arm being stretched open and tilted during puncture, leading to surgical failure.

The utility model provides a kirschner wire guider, which relates to the technical field of medical instruments and comprises a guider main body, and a guider fixing seat is arranged at one end of the guider main body.
