Abstract
The utility model relates to a vein cutter. At peripheral vascular surgery, cardiac surgery and nephrology, autogenous veins are usually required for operations, such as bypass, vascular bypass, arteriovenous fistula forming and the like, and a method that a long incision or a plurality of segmented incisions are cut under full exposure is adopted, thus resulting in great trauma to a patient and long time for operation cutting. The vein cutter comprises a cutting knife and a guiding component; -the guiding component comprises a metal guide wire and a guide mother base; the guide mother base is of a hollow structure and connected with one end of the metal guide wire; both the inside and the outside of the hollow structure are provided with screw threads; the cutting knife is of a hollow structure and a protruded screw-thread structure is arranged at the inside center at the top of the cutting knife; the outer wall of the cutting knife is in a waveform shape; the wave trough of the waveform is a knife edge part and the wave crest of the waveform is a blunt smooth part; and one end of the metal guide wire, which is connected with the guide mother base is connected with a detachable guide head or a detachable cutting knife. The vein cutter has the characteristics of convenience, high efficiency and less trauma, reduces the trauma to the patients as well as obviously shortens the operation time.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of vein cutting device.
Technical background
Vascular surgery, department of cardiac surgery and kidney internal medicine usually need to take from operations such as vena systemica (being mainly great saphenous vein) is put up a bridge, blood vessel bypass, arteriovenous fistula shaping around.Cutting of autogenous vein still do not have special-purpose operating theater instruments at present, generally adopt a long otch or a plurality of otch of segmentation to expose the way that cuts down fully, following shortcomings are arranged: 1,, very big to patient's wound because adopt a long otch or a plurality of otch of segmentation; 2, time of cutting of operation is long.
The utility model content
The technical problem that this utility model solved provides the vein cutting device that a kind of mechanism is simple, easy to use, efficient, wound is little.
For solving above-mentioned technical problem, the technical scheme that this utility model is taked:
Special character of the present utility model is: described vein cutting device comprises and cuts cutter, guiding part, and guiding part comprises metal wire seal wire, guiding female seat, and the guiding female seat is provided with the hollow structure of screw thread inside and outside being and is connected with an end of metal wire seal wire; The described cutter that cuts is a hollow structure, and the inboard center at its top is provided with outstanding helicitic texture; The described outer wall that cuts cutter is a waveform shape, and its trough is a knife edge part, and crest is the passivity smooth part; The end that described metal wire seal wire is connected with the guiding female seat connects dismountable target seeker or cuts cutter.
Above-mentioned target seeker is smooth round end cap-shaped structure.
Above-mentioned metal wire seal wire is arranged with the plastic skin cover outward.
The length of above-mentioned metal wire seal wire is 70-90cm.
Compared with prior art, the beneficial effects of the utility model:
This utility model adopt to extract and cutting in conjunction with design, only need the long otch of two 1-2cm can finish operation, have conveniently, efficient, characteristics that wound is little, both reduced patient's wound, obviously shorten operating time again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of guiding part.
The specific embodiment
Below in conjunction with the drawings and specific embodiments this utility model is elaborated.
Referring to Fig. 1,2, this utility model comprises and cuts cutter 1, guiding part, and guiding part comprises metal wire seal wire 2, guiding female seat 3, and guiding female seat 3 is provided with the hollow structure of screw thread inside and outside being and is connected with an end of metal wire seal wire 2; The described cutter 1 that cuts is hollow structure, and the inboard center at its top is provided with outstanding helicitic texture 4; The described outer wall that cuts cutter 1 is a waveform shape, and its trough is a knife edge part, and crest is the passivity smooth part; The end that described metal wire seal wire 2 is connected with guiding female seat 3 connects dismountable target seeker 5 or cuts cutter 1.
The metal wire seal wire 2 outer plastic skin covers that are arranged with.
The length of metal wire seal wire 2 is 70-90cm.
Using method of the present utility model:
(1) cuts vein one end skin surface at need and do otch, be about 1-2cm, after appearing vein and cutting off, target seeker 5 is installed in metal wire seal wire 2 is provided with an end of guiding female seat 3 and stretches into intravenous and send into, arrive the precalculated position to far-end.
(2) after target seeker 5 arrived the precalculated position, skin surface was done second otch, appeared after vein cuts off target seeker 5 to be stretched out vein, and target seeker 5 is screwed off, and screwed on and cut cutter 1.
(3) the outer metal wire seal wire 2 of first otch is stayed in pulling, need is cut vein pull out externally, and trunk venous side shoot slips in the groove that cuts cutter 1 (wave trough position), is cut off by blade.
