The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to Fig. 1 to Fig. 4, disposable surgical electrode cutter agent structure of the present invention comprises: handwriting 1 and the electrode cutter head that is fixed on handwriting 1 one ends with streamlined contour.
Referring to Fig. 5 to Fig. 7, the electrode cutter head is to be used to realize that TURP and electricity coagulate the parts of operation, comprises cutter head main body 2 and the anti-loose structure that is used for matching with handwriting 1.Specifically; Anti-loose structure is the polyhedron 3 of regular polygon for the cross sectional shapes in above-mentioned cutter head main body 2 outside formation; It also can be multiple tracks convex tendon 4; Certainly, anti-loose structure also can have polyhedron 3 and convex tendon 4 concurrently, and this anti-loose structure can prevent well that the electrode cutter from taking place loosening or rotation in the course of the work.Cutter head main body 2 should be a kind of electric conductivity good metal material, preferred 0Cr18Ni9; And anti-loose structure should adopt ambroin to process, to improve the safety of electrode cutter head.
Wherein, holder 5 is arranged on the inside of handwriting 1, and its inwall contacts with cutter head main body 2, and is promptly as shown in Figure 2, and an end of cutter head main body 2 stretches in the inwall of holder 5.Holder 5 mainly plays a part also can play certain fixation through blocking cutter head main body 2 simultaneously for the power supply of electrode cutter head.
For the electrode cutter head is connected with handwriting 1 reliably, an end that is connected with the electrode cutter head in handwriting 1 is formed with the locking mechanism that matches with the anti-loose structure of electrode cutter head.As preferred version, to the anti-loose structure of former electrodes cutter head, the locking mechanism of handwriting 1 then is the slot 10 that partly constitutes interference fit with the anti-loose structure of electrode cutter head.That is to say;, anti-loose structure just forms the structure that cooperates with polyhedron 3 when being polyhedron 3 in the slot 10; When anti-loose structure is multiple tracks convex tendon 4, just form the structure that cooperates with multiple tracks convex tendon 4 in the slot 10, certainly; When the scheme that adopts them to combine is that slot 10 just is provided with the structure that cooperates with both.So, in electrode cutter head and handwriting 1 through after the interference fit, both not only connect reliable and also sealing fine; As a kind of preferred version, polyhedron 3 is preferably hexahedron.
In order to further facilitate operation and to strengthen the frame for movement of handwriting 1, form anti-skidding burr 11 at the outer surface of handwriting 1, can effectively prevent like this sliding stop conveniently gripping the operation that undergos surgery.As a kind of optimal way, handwriting 1 is the plane at the outer surface that forms these anti-skidding burr 11 places, and this has better skidproof effect than on curved surface and sphere, forming burr.And the burr 11 of formation can not only play anti-skidding effect, can also doublely do reinforcement and play the effect of strengthening handwriting 1 mechanical strength.
Suitability for industrialized production and practical set for ease, handwriting 1 is made up of handwriting loam cake 12 and handwriting lower cover 13, and both can complement each other to form an integral body.Fig. 4 shows a kind of structure of preferred handwriting lower cover 13; Its inside and edge have formed a plurality of assembling steps 14; Handwriting loam cake 12 then is formed with the structure that cooperates with assembling step 14 in the corresponding position; Both can be cooperatively interacted, and after cooperation, adopt the seamless fusion joining process of ultrasound wave to make it form reliable and the superior integral body of sealing.Compare with common snap, the sealing of this programme improves greatly.
In addition; The phenomenon that circuit board 6 becomes flexible may appear in Product transport and use; In order effectively to address this problem; Be formed with the platform that is used to place circuit board 6 in the inside of handwriting 1, and be provided with uniform distribution around the platform, be used for blocking reliably the location buckle of circuit board 6, can also play the effect of the mechanical strength that improves handwriting 1 simultaneously.
Need to prove, owing to be disposable products, want strict control working environment during manufacturing, also should carry out ethylene oxide sterilizing after the packing, and parsings of sterilizing, verify.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
