Abstract
The utility model provides a single bend surgical knife head, which adopts the structure that the knife head comprises a conducting handle, a work head and an insulating cover, wherein the insulating cover is sleeved on the outer wall of the middle part of the conducting handle; and a conducting terminal is arranged at the upper end of the conducting handle, and the lower end thereof is connected with the work head through a bend. Compared with the prior art, the single bend surgical knife head has the advantages of reasonable design, simple structure, safety and reliability, convenient use and the like. The knife head is mainly applied in the treatment of organ diseases inside incisions, thereby achieving favorable value in promotion and use.
Description
Technical field
This utility model relates to a kind of operating theater instruments, specifically a kind of single bending of the hand art electric knife head.
Background technology
Electrosurgical is a kind of surgical knife tool commonly used, the normally straight shape of the working head of the electric surgical knife bit of prior art, be mainly used in cutting, the calcination treatment of skin histology, the deficiency that the electric knife head of prior art exists in actual clinical is that it can only be to the treatment that undergos surgery of the tissue in doctor's sight line or organ, and to surpassing intraorganic other position of sight line, such as some organ in the edge of a knife is done to burn or scald treatment, be typically treatment common arrhythmia atrial fibrillation (AF), straight shape cutter head then obviously exists unable to do what one wishes.
Summary of the invention
The purpose of this utility model provides a kind of single bending of the hand art electric knife head.
Single bending of the hand art electric knife head of the present utility model is realized in the following manner, its structure is made up of conduction handle, working head and insulation sleeve, insulation sleeve is enclosed within on the outer wall at conduction handle middle part, and the upper end of conduction handle is provided with conducting end, and the lower end of conduction handle is by the connection working head that turns round.
The beneficial effects of the utility model are: the part of cutter head front end bending can put in the edge of a knife carries out corresponding treatment to organ inside.

Accompanying drawing 1 is the structural representation of single bending of the hand art electric knife head;
Accompanying drawing 2 is circular section shape sketch maps of working head;
Accompanying drawing 3 is elliptical shape in cross-section sketch maps of working head;
Accompanying drawing 4 is rectangle tee section shape sketch maps of working head.
Description of reference numerals: conduction handle 1, insulation sleeve 2, turn round 3, working head 4.
The specific embodiment
With reference to Figure of description single bending of the hand art electric knife head of the present utility model is done following detailed explanation.
As shown in Figure 1, single bending of the hand art electric knife head of the present utility model is made up of conduction handle 1, working head 4 and insulation sleeve 2, insulation sleeve 2 is enclosed within on the outer wall at conduction handle 1 middle part, and the upper end of conduction handle 1 is provided with conducting end, and the lower end of conduction handle 1 is by the 3 connection working heads 4 that turn round.
Shown in accompanying drawing 2-4, the cross section of working head 4 is circle, oblateness or rectangle.
3 the angle of turning round greater than 60 degree less than 180 degree.
Embodiment:
Choose valve atrial fibrillation patient 100 to 200 examples, excision left and right sides auricle after anesthesia, mid-sternal incision, extracorporeal circulation, heart stop to beat, right atrium, interatrial septum otch at first carry out the elbow electric knife and melt.According to improvement labyrinth pathway, carry out pulmonary vein, right atrium and left atrium, Ma Shi ligament and unite ablation under intracardiac, the visceral pericardium, carry out valve replacement surgery then.Operation vein on the same day is given and amiodarone 800-1000mg, next day the oral 200mg that changes into, every day 1 time, logotype June.Heart rate is lower than 60 times/minute or 3 degree conduction blocks should be stopped using, and atrial fibrillation recurrence can electrical conversion or continued to take amiodarone.Follow up a case by regular visits to behind March, June, the December.Sorted material, data draw experiment conclusion.Identify.By in July, 2008 clinical practice 42 routine patients, obtain good clinical effectiveness.Atrial fibrillation melts time 5 ~ 29min (15.05 ± 5.85) not to be had dead and the atrium is broken hemorrhagely, and 1 ~ 15 month (5.4 ± 4.7) are followed up a case by regular visits in outpatient service, atrial fibrillation healing success rate 74.3%.
Claims (3)
1, single bending of the hand art electric knife head is characterized in that comprising conduction handle, working head and insulation sleeve, and insulation sleeve is enclosed within on the outer wall at conduction handle middle part, and the upper end of conduction handle is provided with conducting end, and the lower end of conduction handle is by the connection working head that turns round.
2, single bending of the hand art electric knife head according to claim 1, the cross section that it is characterized in that working head are circular or oblate.
