Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of openheart surgery drag hook.
Background technology
, it is necessary to cut off plump interventricular septum through sustainer entrance in the surgical operation of hypertrophic obstructive cardiomyopathy.And
In this kind of patient, abnormal plump interventricular septum usually blocks the visual field of distant place interventricular septum under aorta petal, to operations research
And accurate excision causes larger interference.Therefore, need to push the interventricular septum for stopping the visual field aside with drag hook in art, while drag hook is neither
It can stop that patient's sight can not disturb surgery excision again.At present, openheart surgery is generally wide type staight shank with drag hook, for through sustainer
The intra-ventricle operation technique of valve is very unfavorable, so that needing assistant to push interventricular septum aside with finger during most of operation, to patient
Bring very big inconvenience.
Utility model content
There is provided a kind of heart for expanding the patient visual field in order to solve problems of the prior art for the utility model
Operation retractor.
In order to realize above-mentioned purpose, the technical solution of the utility model is：A kind of openheart surgery drag hook, the drag hook
For strip, successively including handle, first paragraph drag hook and second segment drag hook, the first paragraph drag hook exists with the second segment drag hook
Angled at flex point to set, the second segment drag hook end is provided inwardly with a barb.
Preferably, the first paragraph drag hook and the second segment drag hook are in 130 degree of angles.
Preferably, circular arc of the second segment drag hook lateral surface provided with elongatedness direction is recessed.
130 degree of angles of a kind of openheart surgery drag hook that the utility model is provided, first paragraph drag hook and second segment drag hook are set
Put, the angle pushed aside is needed when fitting into operation, the barb that the second segment drag hook end is inwardly set makes drag hook more stable
It is difficult to break off relations, the circular arc depression of second segment drag hook lateral surface facilitates the operation of scalpel, the utility model is simple in construction, uses
It is convenient.
Brief description of the drawings
Fig. 1 shows the structural representation of the utility model drag hook；
Fig. 2 shows the top view of the utility model drag hook.
