The surgical instrument comprises a jaw assembly, a sleeve assembly, an angle steering part, a locking part and a transmission mechanism, and the jaw assembly is rotatably connected with the sleeve assembly through the angle steering part; the sleeve assembly comprises an outer sleeve, and the outer sleeve is connected with the locking piece through a transmission mechanism so as to selectively drive the locking piece. The outer sleeve moves towards the far side to sequentially pass through a first stroke and a second stroke, and when the outer sleeve moves towards the far side in the first stroke, the nail abutting seat rotates to a first preset angle, and the locking piece is driven to move to a locking state; and during the far-side movement in the second stroke, the nail propping seat rotates from a first preset angle to a closed state, moves relative to the locking piece in a non-driving manner, and keeps the locking piece in a locking state. Before the jaw assembly closes and clamps the tissue, the locking piece is in a locking state, that is, no matter what thickness the jaw assembly clamps the tissue, the locking piece can lock the jaw assembly without affecting the outer sleeve to continue to move towards the far side to drive the jaw assembly to be closed at the same time.

The invention relates to the technical field of building construction, and discloses a deep foundation pit inner support dismantling device and a using method.The deep foundation pit inner support dismantling device comprises a bottom plate, universal wheels are rotationally installed at the bottom of the bottom plate, a cutting device and a positioning device are arranged at the top of the bottom plate, and the cutting device comprises a shell, a supporting table, a rotating motor, a rotating shaft, a first baffle and a saw blade; the positioning device comprises a rack, a gear, a driving shaft, a rotating seat and a rotating disc, and further comprises an adjusting device and a protection device. According to the device, by adjusting the cutting speed and the operation mode, the fret saw can ensure that the cutting face is smooth and the size is accurate, the positioning device can accurately adjust the position and angle of the saw blade, the cutting precision is further improved, and through positioning of the gear rack and the rotating disc, the position of the dismounting device can be adjusted in the displacement state of the bottom plate part; when the ground of a construction site is not enough to support the device to continuously move, normal cutting of the device is guaranteed, and the practicability of the device is improved.

The present invention provides an anti-collision device and a lithography device, wherein the anti-collision device includes an anti-collision component and a control component. When an external force hits a buffer component in the anti-collision component, the buffer component pushes the piston component in the anti-collision component to move toward a pressure chamber located in a shell of the anti-collision component to compress the pressure chamber, and the pressure chamber generates a reaction force, thereby buffering the external force. At the same time, when the buffer component pushes the piston to move toward the pressure chamber, when the sensor installed on the buffer component and the sensor installed on the shell separate from each other or approach each other to a predetermined distance, the control component issues an instruction. In this way, when the anti-collision device is used to prevent the motion table from collision, it can not only buffer the force generated by the external force collision, but also control the movement of the motion table by issuing instructions through the control component, thereby avoiding the problem of damage to the motion table caused by secondary or multiple collisions caused by the continued movement of the motion table.

The utility model relates to the technical field of medical equipment, and provides a medical operating bed base which comprises two moving plates and further comprises a supporting block, the center of the top of the supporting block is fixedly connected to one side of the outer surface of one moving plate, sliding columns are embedded in the two moving plates in a sliding mode, and the sliding columns are connected with the supporting block in a sliding mode. The outer surface of one sliding column is movably sleeved with two first cross plates. According to the device, the two first cross plates start to be lifted, the two first cross plates drive the second rotating column to move upwards while being lifted, the second rotating column drives the other movable plate to be lifted continuously, and along with gradual lifting of the other movable plate, the other sliding column in the second rotating column starts to move backwards; and along with continuous movement of the other sliding column, the two second cross plates start to gradually lift upwards by taking the rotating column I as an axis, so that better lifting can be achieved, a doctor can perform lifting adjustment according to needs, and the working efficiency of the whole operating bed is improved.

A patient transport apparatus with a seat assembly to support a patient. A rear assembly pivots between first and second rear positions, and a stair rear position. A ski is selectively pivotable relative to the rear assembly between a plurality of ski positions. A carrier is coupled between the rear assembly and the ski and is operable between: an unlocked state where relative movement between the ski and the rear assembly is permitted, and a locked state where the carrier inhibits relative movement between the ski and the rear assembly. Movement of the rear assembly from the first rear position towards the second rear position changes operation of the carrier from the unlocked state to the locked state such that continued movement of the rear assembly into the rear stair position arranges the rear assembly and the ski for engagement with stairs.
