Specific embodiment

Embodiment one

As shown in Figure 1 and Figure 2, Multifunctional nerve described in the utility model embodiment one monitors knife, the technology hand implemented Section basis is the structure of the cutter body that jaw type is formed by using nip part as blade portion, and shaft portion is two sections, i.e., knife bar portion I 31, Knife bar portion II 32, the end in each section of knife bar portion is correspondingly connected with one section of knife handle 4 and the front end in each section of knife bar portion is correspondingly connected with One section of blade portion, composition conducting route, the technical solution implemented are between the knife handle 4 and corresponding knife bar portion, blade portion, The conducting branches of formation first is that carrying out separation and the functions such as cutting bleeding, further, the technology that the utility model is implemented Means are the Neural monitoring purposes completed in art, i.e., separate and cutting bleeding is combined in one with above-mentioned, realize institute engaging portion Divide the multi-functional purpose in use process.

Accordingly for the above-mentioned separation to be implemented and cutting bleeding function come to II 32 connection structure of knife bar portion carry out with Lower analysis:

The knife bar portion II 32 implemented is wherein one section in two knife bar portions, the knife bar portion II 32 and the knife handle 4 to connect Between be arranged knife portion connector 10 and with the knife portion connector 10 be interface enable the conducting branches in knife bar portion II 32 in knife handle 4 The ultrasound knife connecting line 5 of portion's clamping is connected, to complete the implementation to II 32 latter end of knife bar portion；

Meanwhile ultrasonic cutter head 1 is arranged in the blade portion for II 32 front end of knife bar portion implemented, meanwhile, the ultrasound that will be implemented Cutter head 1 is designed to the shape with certain angle with the end face of corresponding II 32 front end of knife bar portion in vertical state or according to demand State, to realize the fine separation and cutting bleeding behaviour for carrying out that different operations require in art on the basis of combining Neural monitoring knife Make；

Further, the above-mentioned Neural monitoring function to be implemented to carry out I 31 connection structure of knife bar portion following point Analysis:

The knife bar portion I 31 implemented is wherein one section in two knife bar portions, 4 end of knife handle to connect with the knife bar portion I 31 End setting monitors terminal 9 and enables 4 end of the conducting branches in knife bar portion I 31 and knife handle by the monitoring terminal 9 The Neural monitoring connecting wire 6 at end is connected, to complete the implementation to I 31 latter end of knife bar portion；

Simultaneously as monitoring terminal 9 has the monitoring conducting wire 8 drawn, I 31 front end of knife bar portion implemented is by being somebody's turn to do The Neural monitoring probe 2 that conducting wire 8 connects blade portion is monitored, then 2 part bare front end 1mm of the Neural monitoring implemented probe is made For conductive region, to form exposed portion's conductor 21；

As Figure 1-1, default electric current and electric current are releasably monitored using the technological means of exposed portion's conductor 21 It can adjust as needed, in addition to this, any cutter hub position outer surface including knife bar portion, knife handle and blade portion is adopted It is protected with bio-safety insulating coating, thus the peace for preventing the accuracy of stimulated current shunt influence electromyography signal and equipment from using Quan Xing.

In conclusion the insulation hinge 7 that the knife bar portion I 31 of above-mentioned implementation and knife bar portion II 32 are passed through close blade portion is living Dynamic connection forms nip part structure, so that being formed is both ultrasound knife simultaneously but also with the monitoring cutter hub of Neural monitoring function, meanwhile, Also there is the particular procedure operational motion that can be realized by nip part；Above-mentioned realized function is specially, on the one hand, ultrasound Cutter head 1, knife bar portion II 32, knife handle 4 and ultrasound knife connecting line 5 are connected with ultrasound knife host, complete cutting bleeding effect, another party Face, Neural monitoring probe 2, knife bar portion I 31, knife handle 4 and Neural monitoring connecting wire 6 are connected with Neural monitoring instrument, form signal Stimulated side loop, to realize Neural monitoring function.

Multifunctional nerve described in the utility model embodiment one monitors knife, implements above-mentioned technological means, overcomes previous Nerve electrophysiological monitoring present in operation can not carry out simultaneously with surgical procedures, and result in a finding that the nervous function damage time prolongs Late, neurotrosis complication increases；So that Multifunctional nerve monitoring knife is overcome such case using the technical solution, can really realize The purpose that neurotrosis risk is significantly reduced under Neural monitoring carries out separation and while cutting bleeding to required during surgery The neural point being monitored can implement whole, instant, accurate monitoring, can find and avoid in time neurotrosis, The safety for improving operation, shortens operating time, reduces the labor intensity of doctor and the medical treatment cost of patient.

Specific to above-mentioned implementation means application actually for the technical solution can prolongation structure, for example, in thyroid gland Recurrent nerve " real-time monitoring " in art can be achieved in art, connect " Neural monitoring knife " with Neural monitoring equipment in art, form letter Number stimulated side loop, combines with the existing signal receiving end loop of nerve, realizes that Neural monitoring knife finely divides in art From and cutting bleeding operation simultaneously, using the releasable monitoring default electric current (electricity in the part Neural monitoring probe distal end exposed 1mm Stream can be adjusted as needed), monitoring knife rest part application bio-safety insulating coating protection prevents stimulated current shunt influence Electromyography signal accuracy and equipment safety in utilization；Electric signal is transferred to monitoring mind by signal stimulus end ring road by monitoring system Through the part monitoring probe bare front end 1mm, small exposed part acts on recurrent nerve or its adjacent tissue, excites recurrent nerve It forms nerve impulse and conducts to muscle generation electromyography signal is dominated, electromyography signal is returned by the signal receiving end of monitoring system Host forms electromyogram (EMG) waveform and prompt tone, and then realizes real-time or dynamic evaluation nerve function in the course of surgery Can, accurate and timely understanding nervous function, " real-time monitoring mode " takes into account continuous monitoring and is completed at the same time myoelectricity function in surgical procedures Advantage can be monitored, and flexibly controllable advantage completely may be used convenient for identification positioning nerve for interruption monitoring pattern detection time-histories, site Replace classical Neural monitoring probe；

Meanwhile in specific implementation, meticulous optimum choice has been done to the selection of each component, also to guarantee its safety, excellent Benign, reliability, practicability etc., biocompatibility meet the requirement such as GB/T 16886.1-2011.

Embodiment two
