The improvement being further used as technical solutions of the utility model, described scissors is all hinged with connection piece at the handle of a knife end of two panels blade, and the end of two panels connection piece is rotatably connected by the 2nd pivot, and the far-end of described pull wire is connected on described 2nd pivot.
The improvement being further used as technical solutions of the utility model, described 2nd pivot is provided with the torsional sprig that can open described scissors cutter head.
It is further used as the improvement of technical solutions of the utility model, described Handheld Division comprises hand-held sleeve, the described front end of hand-held sleeve is docked with the near-end of sleeve pipe, the end of hand-held sleeve is provided with hinged seat, described hinged seat is hinged with the lever depression bar stretched to the upper and lower both sides of hand-held sleeve, described traction mechanism comprises the towbar of sleeve in described hand-held sleeve, the front end of towbar is connected with pull wire, described hand-held sleeve offers chute on just sidewall to described lever depression bar, it is provided with two ends stretch-draw connecting rod hinged with lever depression bar and towbar respectively through described chute, described stretch-draw connecting rod favours towbar and arranges, when pressing described lever depression bar, stretch-draw connecting rod can push up backward and push away towbar and move backward along hand-held sleeve.
The improvement being further used as technical solutions of the utility model, sleeve pipe be mutually 150 �� of angles by being bent to form two sections.
The improvement being further used as technical solutions of the utility model, described boot proximal end is apart from described bending 10cm or 13cm or 16cm or 19cm.
The beneficial effects of the utility model: when operating in art, by the small holes opened on the body surface wall of the chest, scissors is deeply needed by sleeve pipe the position sheared, operative doctor is operated in vitro by Handheld Division, control scissors direction is also by the cutter head opening and closing of traction mechanism controls scissors, thus realizes the operation of the Minimally Invasive Surgery in cardiac surgery operation. Simultaneously, in order to avoid because of Handheld Division change by a relatively large margin, and make sleeve pipe extrude patient chest cinclides hole edge, cause need not damage soft tissue, the utility model arranges bending on sleeve pipe, make sleeve pipe be mutually angle one section stretched in the wall of the chest and one section that is positioned at wall of the chest hole, thus facilitate patient to operate, lower and possibility is oppressed at patient's minimally invasive hole edge.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model one-piece construction schematic diagram;
Fig. 2 is the utility model using state schematic diagram.
Embodiment
With reference to Fig. 1, Fig. 2, that show the concrete structure of the better embodiment of the utility model. The constructional feature of each element of the utility model will be described in detail below, if and when being described to direction (upper and lower, left and right, before and after), it is taking the structure shown in Fig. 1 as reference describes, but actual user of the present utility model is to being not limited thereto.
See Fig. 1, the utility model provides a kind of Minimally Invasive Surgery scissors, comprise sleeve pipe 1, it is located at the scissors 2 of described sleeve pipe 1 far-end and it is located at the Handheld Division 3 of described sleeve pipe 1 near-end, described sleeve pipe 1 is provided with bending 11, sleeve pipe 1 is by bend that 11 formation are mutually angle two sections, described scissors 2 comprises the blade 22 connected in the middle part of two panels by the first pivot 21, scissors 22 is arranged on the far-end of sleeve pipe 1 by described first pivot 21, scissors 22 has the cutter head stretching out sleeve pipe 1 far-end and the handle of a knife embedded in described sleeve pipe 1, the pull wire 4 being connected with described handle of a knife it is provided with through described sleeve pipe 1, described Handheld Division 3 be provided with can pull wire 4 described in stretch-draw so that the cutter head of scissors 2 completes the traction mechanism of shear action.
Wherein, described scissors 2 is all hinged with connection piece 23 at the handle of a knife end of two panels blade 22, the end of two panels connection piece 23 is rotatably connected by the 2nd pivot 24, the far-end of described pull wire 4 is connected on described 2nd pivot 24, described 2nd pivot 24 is provided with the torsional sprig that can open described scissors 2 cutter head, after the effect of traction mechanism is eliminated, scissors cutter head can automatically open under the effect of torsional sprig, to prepare second time shear action.
Described Handheld Division 3 comprises hand-held sleeve 31, the front end of described hand-held sleeve 31 is docked with the near-end of sleeve pipe 1, the end of hand-held sleeve 31 is provided with hinged seat 32, described hinged seat 32 is hinged with the lever depression bar 33 stretched to hand-held sleeve about 31 both sides, described traction mechanism comprises the towbar 34 of sleeve in described hand-held sleeve 31, the front end of towbar 34 is connected with pull wire 4, described hand-held sleeve 31 offers chute on just sidewall to described lever depression bar 33, it is provided with two ends stretch-draw connecting rod 35 hinged with lever depression bar 33 and towbar 34 respectively through described chute, described stretch-draw connecting rod 35 favours towbar 34 and arranges, when pressing described lever depression bar 33, stretch-draw connecting rod 35 can push up backward and push away towbar 34 and move backward along hand-held sleeve 31.
See Fig. 2, when art operates, by the small holes 5 opened on the body surface wall of the chest, scissors 2 is deeply needed by sleeve pipe 1 position sheared, operative doctor is operated in vitro by Handheld Division 3, control scissors 2 direction is also by the cutter head opening and closing of traction mechanism controls scissors 2, thus realizes the operation of the Minimally Invasive Surgery in cardiac surgery operation.
