Embodiment
With reference to the accompanying drawings and examples, the utility model is expanded on further.In the following detailed description, only pass throughBright mode describes some one exemplary embodiments of the present utility model.Undoubtedly, one of ordinary skill in the art can be withRecognize, can be with a variety of modes to described in the case of without departing from spirit and scope of the present utility modelEmbodiment is modified.Therefore, accompanying drawing and description are inherently illustrative, rather than for limiting the protection of claimScope.
As shown in Figures 1 to 12, surgery device, including Handleset 100 and detachably connect with the Handleset 100The binding clip component 200 connect, Handleset 100 described in the present embodiment include left semi-handle and right semi-handle, the left semi-handleIt is integrated with the right semi-handle by ultrasonic bonding.
Referring to figs. 2 and 3 in, the Handleset 100 formed with installation cavity, in the installation cavity of the Handleset 100Rotation is provided with mounting seat 310, and thumb wheel 320 is installed with the mounting seat 310, and thumb wheel 320 passes through key in the present embodiment321 realize with the keyway 311 that is set in mounting seat 310 and are fixedly mounted by clamp nut 330 after connection；The mounting seat 310Be provided with it is parallel with the thumb wheel 320 touch positioning disk 312, it is described to touch end of the positioning disk 312 away from the thumb wheel 320If circumferentially indent is provided with dry contact 313 on face, it is fixedly installed in the Handleset 100 and touches positioning disk with describedThe ripple pearl contact assembly 400 that 312 Elastic Contacts coordinate.
With reference to figure 12, the ripple pearl contact assembly 400 includes steel ball 410 and housing 420, the steel ball 410 and the shellCompression spring 430 is provided between body 420；Be provided with mounting groove 440 in the Handleset 100, the housing 420 with it is describedMounting groove 440 is threadedly coupled；So ripple pearl contact assembly on steel ball 410 and mounting seat 310 by touching the elastic connecting of positioning disk 312Touch, touching has indent contact 313 to agree with steel ball 410 so as to increase electric conductivity on positioning disk 312；When trackwheel 320, dialThe drive of wheel 320 mounting seat 310 rotates, and is fully contacted by steel ball 410 with touching the indent contact 313 on the end face of positioning disk 312,Which not only adds contact area, while binding clip can be made mounting seat is not turned due to fixing for steel ball in operationIt is dynamic, the Arbitrary Rotation of binding clip part can be realized by rotating thumb wheel, it is more convenient during electric knife so to operate, and makes operation moreBecome easy.
Slided referring again to Fig. 2, in the Handleset 100 and be provided with center fixture 510, the center fixture 510Trigger 520 is connected with by neck, the upper end of the trigger 520 is be hinged with the Handleset 100, in the trigger 520Back-moving spring 530 is provided between portion and the Handleset 100；Slided in the Handleset 100 and be provided with switch briquetting610, switch briquetting 610 is stuck between left semi-handle and right semi-handle in the present embodiment, can be slid back and forth；The HandlesetIn 100 first switch circuit board 621 and second switch circuit board are correspondingly arranged on positioned at the front and rear sides of the switch briquetting 610622；First switch circuit board and second switch circuit board control the solidifying of electric knife and the function of cutting respectively；Switch briquetting is withheld backwardWhen 610, triggering second switch circuit board 622 sends signal by wire to main frame, opens the pattern cut, now cockingTissue smoothly excision can be completed the function that solidifying cutting knife is cut by 520；Forward during push switch briquetting 610, first switch circuit is triggeredPlate 621, start the solidifying pattern of main frame, the grip tissue of cocking 520, by the solidifying conjunction of tissue, complete the solidifying function of solidifying cutting knife.Pass throughFront and rear push switch briquetting, the advantage is that front and rear slight withhold of same finger can realize function that is solidifying and cutting, instead of canFoot-operated effect, make operation and equipment are all simpler easily to grasp, while front and rear withholding is not in while presses two and openThe maloperation of pass, make the risk of operation lower.
The bottom of Handleset 100 is provided with conductive respectively with the first switch circuit board and second switch circuit boardThe aviation plug 630 of connection；Handleset and main frame plug portion can so be separated, in order to which hospital disappears to handlePoison and storage, simultaneously as main frame plug portion can be with general, it is possible to avoid repeat buying main frame plug, save expense.
With reference to figure 4 and Figure 10, the binding clip component 200 include outer bar 210, be slideably positioned in it is interior in the outer bar 210Bar 230 and the insulated connecting piece 290 being arranged between lower jaw and upper jaw, the insulated connecting piece 290 preferably use grooveThe insulating ceramics of shape；The week side of boss of outer bar 210 is coated with pyrocondensation tube layer 211, and the front end of the outer bar 210 is provided with lower jaw220, the rear end of the outer bar 210 is threadedly coupled with the mounting seat 310；The week side of boss of interior bar 230 is also coated with pyrocondensation tube layer,The front end of the interior bar 230 is provided with front tension bar 240, and upper jaw 250 is provided with the front tension bar 240, the interior bar 230Rear end is provided with back stay 260, and the back stay 260 is connected through the mounting seat 310 with the center fixture 510, instituteState and be provided with clamping structure between back stay 260 and the center fixture 510；
With reference to figure 3, the clamping structure includes the buckle 270 being arranged in the center fixture 510, the back stayThe neck being adapted with the buckle 270 is provided with 260；The compressing buckle 270 is provided with the Handleset 100 simultaneouslyThe dismounting button 280 for making the buckle 270 be separated with the neck；During dismounting, dismounting button 280 is pinned, dismounts button 280Buckle 270 is oppressed, buckle 270 is departed from neck, so that back stay 260 releases the connection with center fixture 510, is now revolvedTurn outer bar 210, outer bar screw thread abjection mounting seat 310, then extract binding clip component out handle and realize dismounting；Similarly, when mountedDismounting button 280 is pinned, rotation outer bar 210 fixes outer bar by the internal thread of mounting seat 310, unclamps and tear open after screw thread is screwed into positionButton 280 is filled, now, buckle 270 blocks back stay 260, and installation terminates.
With reference to figure 10 and Figure 11, the front end of the insulated connecting piece 290 is connected by pin 291 with the lower jaw 220,The rear end of the insulated connecting piece 290 is fixedly connected by the spacing circular groove 221 on lower jaw 220 with the lower jaw 220, byFixed in rear portion by spacing circular groove 221 without pin, so as to avoid causing because pin frays internal heat-shrink tubeThe problem of binding clip fails；The upper jaw 250 and the insulated connecting piece 290 by pin-hinges, while with the riveting of back stay 260Connect, when pulling back stay 260, upper jaw 250 closes around pin rotation.Grown on the closing face of the upper jaw 250 along caliperDegree direction has been provided projectingly solidifying crossed belt 251, and by coagulating the design of crossed belt 251, zonula occludens is formed beneficial on the periphery of incised tissue,Bleeding is prevented, while relatively good solidifying conjunction effect can be also produced when coagulating charge-coupled knit.
Known conventional means realization in the prior art can be used by not elaborating part in the utility model.It is described aboveThe only schematical embodiment of the utility model, is not limited to the scope of the utility model.It is any in the artTechnical staff, do not depart from it is of the present utility model design and principle on the premise of made by equivalent variations and modification, all shouldBelong to the scope of the utility model protection.
