Description
Technical field
Medical auxiliary equipment is the utility model is related to, more particularly, to a kind of pipeline dilator.
Background technology
At present, the inner-walls of duct in many patients has a strong impact on that it is strong with blocks such as thrombus, tumour or polyps
Health.To ensure patient vitals' safety, generally require progress surgical operation and cut the thrombus on inner-walls of duct, tumour or polyp etc.
Remove, need to use device for spreading to strut pipeline before excision.It is less to be presently used for strutting the research of the dilator of pipeline, it is existing
There is dilator to be generally the character "door" form structure for being strutted arm by connecting rod and two and being formed, strut arm using two and strut pipeline, strut
Pipeline opening afterwards is line-like structures, and field range is small, visual poor, is unfavorable for operation technique.
The content of the invention
The utility model purpose is to provide a kind of easy to operate, visual good, safe pipeline dilator.
To achieve the above object, the utility model takes following technical proposals：
Pipeline dilator described in the utility model, including the first caliper and the second pincers being integrated by hinge hinge
Body, first caliper include the first tong arm and the first binding clip, and second caliper includes the second tong arm and the second binding clip, described
The bottom of first, second tong arm is provided with finger circle, and the arc with locking tooth is fixed with the madial wall of first tong arm
Locking bar, second tong arm fixedly connected to the inner side the lock being engaged with the arc locking bar；
The left part of first, second binding clip is reclinate arcuate structure, and the end of first, second binding clip is equal
The support that struts being inverted U shape is fixed with, the support that struts includes bow, and the left end of the bow has extended downwardly left bullet
Property bar and its right-hand member has extended downwardly right elastic rod, the upper end of the left and right elastic rod is connected by the axis of guide, positioned at it is left,
Compression spring is arranged with the axis of guide between right elastic rod, is set between the left and right elastic rod on the downside of the axis of guide
There is locking device, the bottom of left and right elastic rod is provided with spherical head protector.
The locking device includes the first locking rack being connected on the left elastic rod and is connected in the right elasticity
Second locking rack of bar, the lock tooth intermeshing on first, second locking rack.
The length of the left and right elastic rod is 2~20cm, and graduation mark is provided with left and right elastic rod.
Compared with existing pipeline dilator, the utility model has advantages below：
（1）It is provided with first, second binding clip and struts support, each struts the left and right elastic rod on support to strut
Arm, that is, share four and strut arm, the pipeline opening visuality after strutting is good, is easy to operation technique；And arc locking bar can adjust
The stretching degree of first, second binding clip, first, second locking rack can adjust the distance between left and right elastic rod, thus can root
According to being actually needed, the degree that struts of pipeline dilator described in the utility model is adjusted, it is applied widely.
（2）Graduation mark on left and right elastic rod can intuitively observe it and insert pipeline depth, to meet needs of performing the operation；
The spherical head protector of left and right elastic rod bottom effectively avoids damage to duct wall, it is ensured that patient safe.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is Fig. 1 supports spending frame closure.
Embodiment
As shown in figure 1, pipeline dilator described in the utility model, including the first caliper being integrated that is hinged by hinge
With the second caliper, the first caliper includes the first tong arm 1.1 and the first binding clip 1.2, and the second caliper includes the second tong arm 2.1 and second
Binding clip 2.2, the bottom of first, second tong arm 1.1,2.1 are provided with finger circle 3, band are fixed with the madial wall of the first tong arm 1.1
There is the arc locking bar 4 of locking tooth, the second tong arm 2.1 fixedly connected to the inner side the lock 5 being engaged with the arc locking bar 4,
It is easy to adjust the opening aperture or closure of first, second binding clip 1.2,2.2；The left part of first, second binding clip 1.2,2.2 is
Reclinate arcuate structure, the end of first, second binding clip 1.2,2.2 be fixed be inverted U shape strut support, strut branch
Frame includes bow 6, and the left end of bow 6 has extended downwardly left elastic rod 7.1 and its right-hand member has extended downwardly right elastic rod
7.2, the length of left and right elastic rod 7.1,7.2 is 6cm and is carved with graduation mark, is easy to observation to strut the insertion depth of support；
The upper end of left and right elastic rod 7.1,7.2 is connected by the axis of guide 8, the axis of guide 8 between left and right elastic rod 7.1,7.2
On be arranged with compression spring 9, one end of the axis of guide 8 is connected on left elastic rod 7.1 and the other end extends right elastic rod 7.2 simultaneously
It is provided with and prevents raising one's hat, compression spring 9 is easy to adjust left and right elastic rod 7.1,7.2 opening rapidly；Positioned at the downside of the axis of guide 8
