Abstract
The invention provides a single-bending rotary electric surgical knife head, which structurally consists of a conductive handle, a working head and an insulating bush, wherein the insulating bush is sleeved on the outer wall at the middle part of the conductive handle, the upper end of the conductive handle is provided with a conductive plug, and the lower end of the conductive handle is connected with the working head through a hinge. Compared with the prior art, the single-bending rotary electric surgical knife head has the characteristics of reasonable design, simple structure, safety and reliability, random adjustment of the angle of the working head, convenient use and the like, and is mainly used for treating diseases in incision of human organs, so the electric surgical knife head has good popularization and using values.
Description
Technical field
The present invention relates to a kind of operating theater instruments, specifically a kind of single-bend rotary operation 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 invention is to provide a kind of single-bend rotary operation electric knife head.
Single-bend rotary operation electric knife head of the present invention 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 conductive plug, the lower end of the conduction handle working head that is connected through the hinge.
The invention has the beneficial effects as follows: the working head of cutter head front end can put in the edge of a knife corresponding treatment is carried out in organ inside easily by the angle of hinge adjustment with the conduction handle.
Description of drawings
Accompanying drawing 1 is the structural representation of single-bend rotary operation electric knife head;
Accompanying drawing 2 is local structure for amplifying sketch maps of Fig. 1;
Accompanying drawing 3-5 is the A-A cross sectional shape sketch map of working head.
Description of reference numerals: conduction handle 1, insulation sleeve 2, hinge 3, working head 4, conductive plug 5.
The specific embodiment
With reference to Figure of description single-bend rotary operation electric knife head of the present invention is done following detailed explanation.
Shown in accompanying drawing 1,2, form by conduction handle 1, working head 4 and insulation sleeve 2 with novel single-bend rotary operation electric knife head, 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 conductive plug 5, and the lower end of conduction handle 1 connects working head 4 by hinge 3.
Shown in accompanying drawing 3-5, the cross section of working head 4 is circle, oblateness or rectangle.
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 the 1-15 month (5.4 ± 4.7) is followed up a case by regular visits in outpatient service, atrial fibrillation healing success rate 74.3%.
Processing gets final product by traditional electrical cutter head processing technique processing, installs and uses identically with the electric knife head of prior art, during use, conductive plug is inserted on the electric knife gets final product, and moves working head and can adjust and conduct electricity angle between the handle, very convenient doctor's operation technique.
Claims (2)
1, single-bend rotary operation 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 conductive plug, the lower end of the conduction handle working head that is connected through the hinge.
2, single-bend rotary operation electric knife head according to claim 1, the cross section that it is characterized in that working head are circular or oblate.
