Description
Technical field
This utility model relates to a kind of single hole doublejointed hospital scissors, belongs to technical field of medical instruments.
Background technology
Thoracoscopic operation uses modern camera technique and high-tech operating theater instruments equipment, and under miniature incision, complete Wicresoft's thoracic surgery new technique of intrathoracic complicated operation, be the direction of following thoracic surgery development.
Thoracoscopic operation only needs the thoracic wall aperture doing 1 ~ 3 1.5 centimetres.Development along with clinical treatment technical merit now only needs an otch to complete thoracoscopic operation.Intrathoracic situation is projected large display screen by small medical photographic head.Surgical field of view can be amplified as required, shows trickle structure, than more clear more flexible under naked eyes direct-view.Judgement and the safety of the therefore exposure of surgical field of view, the manifesting of pathological changes fine structure, Operative Range are better than common open chest surgery.But at present conventional clinically hospital scissors when doing thoracoscopic operation due to the more easy generation cross-reference inconvenience of thoracic wall aperture less use apparatus.Meanwhile, the opening angle of conventional hospital scissors handle when opening needs very large.
Summary of the invention
The purpose of this utility model uses inconvenience, the shortcoming that easy and other apparatuses intersect to solve hospital scissors common in thoracoscopic operation, provides a kind of structure simple, the single hole doublejointed hospital scissors with tangent bend section compact to design.
This utility model adopts following technical scheme: a kind of single hole doublejointed hospital scissors, comprise scissors bit and handle, sliding bar is had between described scissors bit and handle, there is the first joint fulcrum described sliding bar and scissors bit junction, the junction of described sliding bar and handle is provided with second joint point, described sliding bar comprises the first bending section and the second bending section, and the bending direction of described first bending section and the second bending section is contrary.
Further, described first bending section is provided with the first bending summit, second bending section is provided with the second point of the bending end, and the distance of the described first bending summit and scissors bit end is 80-120mm, and the distance of the described second point of the bending end and handle end is 140-160mm.。
Further, described single hole doublejointed hospital scissors adopts medical stainless steel or titanium alloy material to make.
Further, the total length of described single hole doublejointed hospital scissors is 320-420mm.
Further, the distance that described scissors bit opens is 15-25mm.
This utility model structure is simple, design ingenious, the tangent bend section of sliding bar is designed to the operation of other apparatuses in otch in thoracoscopic operation and provides certain space, the sliding bar design of doublejointed makes hospital scissors folding on less thoracic wall free, use more convenient and quick, folding is sensitiveer.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is left view of the present utility model.
Reference numeral: scissors bit 1, sliding bar 2, first articulare 2-1, second joint point 2-2, the bending summit 4, second of handle 3, first point of the bending end 5.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
As Figure 1-Figure 2, a kind of single hole doublejointed hospital scissors, comprise scissors bit 1 and handle 3, sliding bar 2 is had between scissors bit 1 and handle 3, there is the first joint fulcrum 2-1 sliding bar 2 and scissors bit 1 junction, the junction of sliding bar 2 and handle 3 is provided with second joint point 2-2, sliding bar 2 comprises the first bending section and the second bending section, the bending direction of the first bending section and the second bending section is contrary, S-shaped bending, first bending section is provided with the first bending summit 4, second bending section is provided with the second point of the bending end 5, first bending summit 4 is 80-120mm apart from the tip lengths of scissors bit 1, second point 5 position, the bending end, is near handle 3 place, distance handle 3 tip length is 140-160mm.The angle of bend of the first bending section is 130-160 °, and the angle of bend of the second bending section is 135-160 °.
It is 320-420mm that single hole doublejointed hospital scissors in this utility model adopts medical stainless steel or titanium alloy material to make total length,
In thoracoscopic operation, scissors bit 1 is until the second point 5 place, the bending end enters in otch completely, hold handle, on sliding bar 2, second joint fulcrum 2-2 drives the first joint fulcrum 2-1 horizontal movement thus drives the folding of front end scissors bit 1, and the design of doublejointed sliding bar makes folding not need to take larger space scissors bit both sides can be made to open reach 15-25mm compared with the shears of simple joint fulcrum.Single hole doublejointed hospital scissors stretches into the S-shaped bending of part of otch, is conducive to the expansion of surgical field of view in bending space, can also reserve more space for using while other apparatuses in handle hole, can not use inconvenience because intersecting to cause.
This utility model is also applicable to medical tissue and cuts, medically meticulously to cut.
