Abstract
The utility model relates to a medical device, in particular to an edge compressing type fixing jacket for an operation cannula. The edge compressing type fixing jacket comprises a clamp bucket, a sleeve, an upper handle, a spring, screw caps, two guiding shafts and a lower handle, wherein the clamp bucket is an inverted circular platform body without upper and lower bottom surfaces; one end of the upper handle is combined with the clamp bucket; the strip-shaped lower handle integrated with the sleeve into a whole is arranged on a side wall of the sleeve; the two guiding shafts vertically penetrate through the upper handle and the lower handle, and is movably matched with the upper handle; disc bodies are arranged on identical horizontal positions of the upper handle and the lower handle, between the two guiding shafts; and the spring is arranged between the two disc bodies. The jacket can securely fix the cannula, and can allow the cannula to enter a deeper site, so that the accuracy and the stability of an operation are improved greatly.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of edge compression type surgical cannula fixed cover.
Background technology
In heart or Great Vessel Operations, usually need blood vessel is carried out intubate, be directly to take pipe to carry out intubate with hands entirely in the present operation, for during deep operation the time, hands can't put in the otch deep.At this moment because pipe is softer, and handgrip part from tip away from, the accuracy of intubate is greatly affected.
The utility model content
This utility model provides a kind of edge compression type surgical cannula fixed cover of energy stable holding intubate for solving the deficiencies in the prior art.
The scheme that solves this utility model technical problem is: edge compression type surgical cannula fixed cover is made of clam(shell) bucket, sleeve, upper handle, spring, nut, the axis of guide and lower handle.Clam(shell) bucket is rounding stage body supreme, bottom surface, and an end of the upper handle of strip is combined as a whole with clam(shell) bucket.Sleeve is cylindrical shape, and having on the sidewall of sleeve with sleeve is the lower handle of holistic strip.The axis of guide is that upper and lower side all has the screwed round bar of die and lower end, and two axis of guides vertically run through handle and lower handle and are in active relationship with upper handle, and the lower end cover of the every axis of guide has nut.On upper handle between two axis of guides and the par position of lower handle a disc is arranged all.Have between described two discs upper and lower end respectively with the spring of described disc welding.During use, only need the upper end of intubate is inserted in the sleeve, the upper end that makes intubate is suitable for reading concordant with sleeve, and again with upper handle with lower handle is past holds together to pinch, clam(shell) bucket namely inserts in the sleeve, and clam(shell) bucket and sleeve are fixed the upper end of intubate.
Adopt such scheme, can reach following effect:
Because clam(shell) bucket and sleeve can be clamped the intubate upper end firmly, and sleeve has also played reinforcement effect to softer intubate, therefore this utility model can not only fixedly secure intubate, and intubate can be sent to than the position, deep, has greatly improved the Stability and veracity of operation.
Description of drawings
Fig. 1 is top view of the present utility model;
Fig. 2 is the A-A profile of Fig. 1.
Among the figure: 1. 7. times handles of handle 4. spring 5. nuts, 6. axis of guides on clam(shell) bucket 2. sleeves 3.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Edge compression type surgical cannula fixed cover is made of clam(shell) bucket 1, sleeve 2, upper handle 3, spring 4, nut 5, the axis of guide 6 and lower handle 7.Clam(shell) bucket 1 is rounding stage body supreme, bottom surface, and an end of the upper handle 3 of strip and clam(shell) bucket 1 are in conjunction with as a whole.Sleeve 2 is cylindrical shape, has on the sidewall of sleeve 2 with sleeve 2 to be the lower handle 7 of holistic strip.The axis of guide 6 is that upper and lower side all has the screwed round bar of die and lower end, and two axis of guides 6 vertically run through handle 3 and lower handle 7 and are in active relationship with upper handle 3, and the lower end cover of the every axis of guide 6 has nut 5.On upper handle 3 between two axis of guides 6 and the par position of lower handle 7 disc is arranged all.Have between described two discs upper and lower end respectively with the spring of described disc welding.During use, only need the upper end of intubate is inserted in the sleeve 2, the upper end that makes intubate is suitable for reading concordant with sleeve 2, holds together to pinch with upper handle 3 and lower handle 7 are past again, and clam(shell) bucket 1 namely inserts in the sleeve 2, and clam(shell) bucket 1 and sleeve 2 are fixed the upper end of intubate.
