Referring to Fig. 1～Fig. 6, embodiment of the invention this utility model embodiment laparoscopic surgery drag hook is provided with handle 1, handle seat 2, swivel nut 3, turning handle 4, fixed cover 5, screw rod 6, first pin 7, adapter sleeve 8, sealing ring 9, fixing head 10, flushing interface 11, drag hook bar 12, trombone slide 13, second pin 14, drag hook seat 15, the 3rd pin 16, drag hook head body 17, drag hook head front portion 18, gib head hole 19, the 4th pin chute 20, the 4th pin 21, the 5th pin 22, the 6th pin 23 and the 5th pin chute 24, the drag hook head comprises drag hook head body 17 and drag hook head front portion 18, and screw rod 6 has the 4th pin chute 20, the 5th pin chute 24; Screw rod 6 is inserted in handle seat 2, and fixed cover 5 is inserted in screw rod 6, and with the 5th pin 22 that fixed cover 5 is fixing with handle seat 2, the 5th pin 22 heads are positioned at the 5th pin chute 24, make screw rod 6 can slide at handle seat 2; Swivel nut 3 is screwed into screw rod 6 and connects, handle 1 is inserted in swivel nut 3 backs to be tightened fixing with handle seat 2, with the 4th pin 21 that fixed cover 5, handle seat 2 and handle 1 is fixing, the 4th pin 21, the 5th pin 22 snap in the 4th pin chute 20, the 5th pin chute 24 just respectively, and screw rod 6 can be slided can not rotate; Turning handle 4 is tightened the back with swivel nut 3 and is fixed with first pin 7.It is fixing that one end of trombone slide 13 is inserted in screw rod 6 usefulness the 6th pin 23, and it is fixing with second pin 14 that drag hook head body 17 rear ends snap in the other end of trombone slide 13; It is fixing that flushing interface 11 is screwed into adapter sleeve 8, drag hook bar 12 be inserted in adapter sleeve 8 tighten fixing, flushing interface 11 just with drag hook bar 12(inside) be communicated with; Adapter sleeve 8 and drag hook bar 12 are inserted in drag hook head body 17 and trombone slide 13, and after sealing ring 9 and fixing head 10 snapped in adapter sleeve 8, adapter sleeve 8 was tightened fixing with handle seat 2; It is fixing that drag hook seat 15 is inserted in drag hook bar 12 usefulness the 3rd pin 16; Have gib head hole 19 on the drag hook head front portion 18, drag hook head anterior 18 is fixing with drag hook head body 17 by welding.
Embodiment of the invention drag hook head body 17 is in that gib head hole 19 is positioned at outside the drag hook bar 12 just when drawing in state, conveniently penetrates stitching thread, increases surgical functions.
Make swivel nut 3 rotations when rotating turning handle 4, swivel nut 3 drives screw rod 6 rotations toward drop-down, screw rod 6 pulling trombone slides 13, and trombone slide 13 pulling drag hook head bodies 17 are toward drop-down, drag hook head body 17 is drawn in the drag hook bar 12, forms drag hook head body 17 shown in Figure 2 and draws in (stretching) state; Counter-rotating turning handle 4 makes swivel nut 3 rotation, and swivel nut 3 drives screw rods 6 rotations and up pushes away, and screw rod 6 promotes trombone slides 13, and trombone slide 13 promotes drag hook head bodies 17 and up pushes away, and drag hook head body 17 is released outside the drag hook bars 12, drag hook head reset (Fig. 1).
The laparoscopic surgery drag hook of the present invention's design, described drag hook head body 17 is used elastic material and is made, and has superpower reset function, and its manufacture method is:
1, drag hook head body 17 adopts the hyperelastic Nitinol of shape memories to make, and it is elementary composition to be: the high-elastic nickel of medical grade (Ti) 50%, titanium (Ni) 50% raw material, raw material is put into interlayer water flowing copper crucible sealed vacuum (10
-3Pa), through the pyrolytic semlting of 1800 degrees centigrade and 2 hours; Because of nickel-titanium alloy material hardness height (380-420HB), in the operation of rolling, need through 4 times rolling, 4 annealing, rolling temperature is 700 ℃, annealing temperature is 5～40 ℃, the sheet material of 5 meters of rolling growth, wide 60 millimeters, thick 0.7mm.Consist of nickel, the titanium of embodiment of the invention Nitinol respectively account for 50% of Nitinol percentage by weight.
2, Nitinol sheet material processing: by smelting and rolling Nitinol formation workblank sheet material, the necessary smooth surface no concave-convex of sheet material and slight crack, because Nitinol sheet material hardness height, sheet material must cut into bar shaped with electric spark, reach the cutting accuracy height, material can not damage; By forming blank after polishing, polishing, the pickling polish.
3, Nitinol sheet material is processed hyperelastic molding: after Nitinol forms blank, put into the shaper internal fixation, the position of corresponding drag hook head body 17 arch sections is the arc that r is 20-25mm in the shaper, arc angle is 140～160 °, the shaper of made-up belt material is put into the heat-treatment furnace high-temperature shaping, temperature control: 480-500 ℃, the time is controlled 18 minutes～22 minutes (special case is 20 minutes);
After the blow-on blank and shaper are put into the water of 23～28 ℃ (being generally about 25 degrees centigrade) fast, blank is cooled to 25～30 ℃ of (room temperature) demouldings, makes the drag hook head body 17 of memory hyperelastic.Drag hook head body 17 after the molding is out of shape under the effect of external force, loses external force and resets to prototype memory case of bending.
The hyperelastic nickel titanium alloy method of shape memory is prior art, makes drag hook head body 17 and is created by the present invention but be used in.Present embodiment is made drag hook head body 17 with a kind of specific process, drag hook head body 17 heads of making have arch section (referring to Fig. 5 top), the radius of arch section is 20～25 millimeters, the arc angle of arch section is 140 °～160 °, it is big to have angle of bend, the precision height, characteristics such as handled easily.
Nitinol memory hyperelastic drag hook head is under parent phase (austenitic state) state, under the effect of external force, cause stress-induced phase transformation to take place, Nitinol is shown be different from the ordinary metallic material mechanical behavior, elastic limit is far longer than ordinary metallic material, does not observe in elastic limit object deformation and causes deformation external force be directly proportional (Hooke's law); Form slippage deformation and distortion variation when stressed greatly, in case external force is cancelled, the strain that Nitinol memory hyperelastic drag hook head can take place to be carried by stress-induced phase transformation will disappear and form super-elasticity (reverse transformation of martensitic phase transformation).
The laparoscopic surgery drag hook of the present invention's design, the structural design drag hook can stretch in apparatus, and in the application of laparoscopic surgery, drag hook head body 17 can be drawn in the drag hook bar 12, and drag hook head and front end thereof can enter human abdominal cavity by the instrumentation passage.
In human abdominal cavity, as long as counter-rotating turning handle 4 makes swivel nut 3 rotation, swivel nut 3 drives screw rods 6 rotations and up pushes away, and screw rod 6 promotes trombone slides 13, and trombone slide 13 promotes drag hook head bodies 17 and up pushes away, and drag hook head body 17 is released outside the drag hook bars 12, the formation (Fig. 1) that resets of drag hook head; The innovation realization drag hook of technology is used in the laparoscopic surgery human abdominal cavity.
The laparoscopic surgery drag hook of the present invention's design, have gib head hole 19 at the drag hook head, in the application of laparoscopic surgery, when drag hook undergos surgery operation in human abdominal cavity, the effect in gib head hole 19 is can penetrate stitching thread to carry out other operation application, increases surgical functions.
Simple deformation or the combination of every embodiment of the invention technical scheme and technical characterictic all should be thought to fall into protection scope of the present invention.
