Description
Technical field
This utility model relates to a kind of rectum resection surgical scissors.
Background technology
The existing rectum resection clinically surgical scissors adopted of performing the operation is existing common shears, be linear shears, in use, doctor needs to use shears excision, and due to operation mouth less, and shears is linear, doctor needs the larger angle of shears inclination then to shear, use quite inconvenient, and after shearing, rectum end is spline-simulating substantially, is unfavorable for the healing in later stage; Just adopting more existing cutter heads to be the shears of arc at last, equally when doing rectum resection operation cannot to get a desired effect.
Utility model content
The purpose of this utility model is to provide a kind of rectum resection surgical scissors, solves existing shears inconvenient when carrying out rectum resection operation, and is unfavorable for the problem that the later stage heals after rectum resection.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Rectum resection surgical scissors, comprises cutter head, the handle of a knife be connected with cutter head, at right angles, described handle of a knife is made up of the upper handle of a knife be detachably connected and lower handle of a knife, and described lower handle of a knife and cutter head are fixedly linked for described cutter head and handle of a knife, described upper handle of a knife is also provided with finger ring, and described lower handle of a knife is provided with scale.
Further, described cutter head forms by blade conjunction with the blade that blade conjunction removably connects, and described blade conjunction and lower handle of a knife are fixedly linked.
Again further, the side that described blade is connected with blade conjunction is in " convex " shape, and the side that blade conjunction is connected with blade is in " recessed " shape; Described blade is the knife edge away from the middle part of blade conjunction side.
Further, one end that described lower handle of a knife is connected with upper handle of a knife is hollow-core construction, and one end that described upper handle of a knife is connected with lower handle of a knife is then socketed in lower handle of a knife; And described upper handle of a knife and lower handle of a knife are interference fit.
This utility model compared with prior art, has the following advantages and beneficial effect:
(1) cutter head of the present utility model and handle of a knife rectangular, excise after then not needing this utility model to tilt when carrying out rectum resection operation, easy to operate, blade of the present utility model only has middle part for sharp simultaneously, front end is not sharp, then its hetero-organization can not be staved when excising, thus avoid causing other tissue damageds, use extremely safe.
(2) handle of a knife of the present utility model is made up of upper handle of a knife and lower handle of a knife, the length of handle of a knife can be regulated, thus better carry out rectum and originally perform the operation, be provided with scale with handle of a knife at present, the position be connected to residing for cutter head that can prepare, thus carry out resection operation accurately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is blade cross section schematic diagram in this utility model.
Fig. 3 is blade conjunction cross sectional representation in this utility model.
Wherein, the parts name that in accompanying drawing, labelling is corresponding is called: the upper handle of a knife of 1-, handle of a knife under 2-, 3-finger ring, 4-scale, 5-blade conjunction, 6-blade.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Figures 1 to 3, rectum resection surgical scissors, comprise cutter head, the handle of a knife be connected with cutter head, at right angles, described handle of a knife is made up of the upper handle of a knife 1 be detachably connected and lower handle of a knife 2, and described lower handle of a knife and cutter head are fixedly linked for described cutter head and handle of a knife, described upper handle of a knife is also provided with finger ring 3, and described lower handle of a knife is provided with scale 4.By above-mentioned setting, when using this utility model, can be tilted shears, and rectum resection operation can be carried out easily, thus alleviate the operation easier of doctor, improve the efficiency of operation, in addition, because lower handle of a knife is provided with scale, the length that shears stretches into can be understood accurately, thus improve the accuracy of excision.
In order to well use this utility model after blade becoming dull, so described cutter head forms by blade conjunction 5 with the blade 6 that blade conjunction removably connects, described blade conjunction and lower handle of a knife are fixedly linked.After due to blade life-time service rust, only blade need be taken off from blade conjunction and change, easy to operate, improve simple service life equally.
Further, conveniently installation, removal of inserts and blade conjunction, the side that described blade is connected with blade conjunction is in " convex " shape, and the side that blade conjunction is connected with blade is in " recessed " shape; Described blade is the knife edge away from the middle part of blade conjunction side.By above-mentioned setting, closely can agree with between blade and blade conjunction, ensure that the stability between blade and blade conjunction; In addition, sharp time in the middle part of blade only has, and leading section is sharp, then can ensure that shears can not cause other tissue damageds when carrying out rectum resection operation, improves the safety that this utility model uses.
In order to make more conveniently to connect between upper handle of a knife and lower handle of a knife, one end that described lower handle of a knife is connected with upper handle of a knife is hollow-core construction, and one end that described upper handle of a knife is connected with lower handle of a knife is then socketed in lower handle of a knife; And described upper handle of a knife and lower handle of a knife are interference fit.In use, because upper handle of a knife and lower handle of a knife are interference fit, so push to handle of a knife make the length of handle of a knife increase or shorten by drawing, thus regulate the length of handle of a knife, doctor is performed the operation more easily.
According to above-described embodiment, just this utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on this utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with this utility model, therefore it also should in protection domain of the present utility model.
