The utility model has the advantages that: the multifunctional endoscope grasping forceps can realize the dual functions of the conventional endoscope grasping forceps and the aspirator, can be operated in a small space, does not need to frequently replace operating instruments, shortens time, reduces operation difficulty, and is simple in structure, good in reliability and convenient to manufacture and maintain.
Drawings
The invention will be further explained with reference to the drawings:
figure 1 is a schematic structural diagram of the present invention,
fig. 2 is a schematic view of a partial structure of the present invention.
In the figure: the device comprises a clamping piece 1, a brace 2, a first sliding groove 3, a traction rod 4, a clamp tube 5, a rotating wheel 6, an aspirator box 7, a cutting groove 8, a sealing ring 9, a rubber plug 10, a clamp body 11, a pull ring 12, a second sliding groove 13, a movable handle 14, a fixed handle 15, a limiting block 16, an aspiration tube 17, a valve 18 and a torsion spring 19.
Detailed Description
As shown in figures 1 and 2, a novel endoscopic forceps for minimally invasive surgery instruments comprises a forceps body 11 and a forceps tube 5, wherein one end of the forceps tube 5 passes through a hole on the forceps body 11 and then extends outwards to form a circle of flange, so that the forceps tube 5 can rotate in the forceps body 11, a rotating wheel 6 is fixedly connected to the forceps tube 5, the forceps body 11 comprises a fixed handle 15 and a movable handle 14, a notch is arranged at one end of the forceps tube 5, which is far away from the forceps body 11, a clamping piece 1 is hinged to the notch, a brace 2 is obliquely and fixedly connected to the clamping piece 1, a first chute 3 is arranged on the brace 2, a pull ring 12 is fixedly connected to one end of the movable handle 14, a second chute 13 is arranged on the pull ring 12, a steel pull rod 4 is arranged in the forceps tube 5, one end of the pull rod 4 is inwards bent to form a hook and then is assembled in the first chute 3, the hook, which is inwards bent, of the pull rod 4 is used as a sliding block to drive the brace 2 to move, the other end of the pull rod 4 is positioned in the second chute 13, the limiting blocks are fixed on the traction rods 4 on two sides of the second sliding groove 13 respectively through welding machines, the traction rods 4 and the forceps tubes 5 are sealed through rubber plugs 10, the traction rods 4 move back and forth along the axes of the rubber plugs 10, drainage ports and an aspirator box 7 sleeved outside the forceps tubes 5 are formed in the forceps tubes 5, the aspirator box 7 is fixedly connected with the forceps bodies 11, the forceps tubes 5 can rotate in the aspirator box 7, a circle of cutting grooves 8 communicated with the drainage ports are formed in the aspirator box 7, and the aspirator box 7 is fixedly connected with an aspirator tube 17 communicated with the cutting grooves 8. The movable handle 14 can drive the clamping piece 1 to move through the pulling rod 4 so as to realize the grasping function of the endoscopic forceps, and then the endoscopic forceps can realize the function of a suction apparatus after the suction tube 17 is communicated with the tissue suction equipment; in addition, the suction box 7 can rotate on the forceps tube 5, thereby realizing that the forceps head can clamp tissues by 360-degree angle conversion according to the needs of the operation.
The contact surface of the clamping piece 1 and the notch is wave-shaped. This configuration facilitates more secure tissue clamping and prevents tissue slippage.
