It is a kind of to perceive high-intensitive early warning ceramic pin knife certainly
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of from the high-intensitive early warning ceramic pin knife of perception.
Background technique
Needle knife used in Hospitals at Present is small needle knife, it is consisted of three parts, respectively handle, straight knife bar and bit shank.
Straight knife bar and bit shank material therefor are steel.But needle knife is often contacted with body fluid, is easy to be corroded.Straight knife bar is thinner, directly
Diameter is generally less than 3mm, is easy brittle failure.
Now there are also another needle knife, its end has endoscope, in addition huge visual equipment and analysis
Software.On the one hand, since this needle knife is excessively huge, it is not able to maintain the flexibility of needle knife.On the other hand, visualization device with point
Analysis software obviously lags behind the process of the operation hour hands knife edge of a knife, unfavorable to the time requirement of operation, brings pain to patient, influences
Treatment, needle knife doctor do not receive the technology very much.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of from the high-intensitive early warning ceramic pin knife of perception.
The technical scheme adopted by the invention is that: it is a kind of from the high-intensitive early warning ceramic pin knife of perception, it is characterised in that: including
Signal lamp, data processing module, power supply, handle, straight knife bar, signal transmssion line, resistance detecting module, bit shank, voice signal
Player;
The signal lamp, data processing module, power supply, voice signal player are arranged in the handle;The resistance
Power detecting module is arranged between straight knife bar and bit shank;The data processing module passes through signal transmssion line and the letter respectively
Signal lamp, power supply, resistance detecting module, the connection of voice signal player, data for measuring the resistance detecting module into
Then row processing controls flashing and the voice signal player plays alarming sound of signal lamp according to the size of power.
Preferably, the resistance detecting module is made of the end of straight knife bar and the starting point of bit shank;The straight knife
The end of bar and the starting point of bit shank are provided with outer ring and inner ring;Force sensor is set in the inner ring;The power passes
Sensor passes through signal transmssion line and data processing module connection communication;The outer ring of the straight knife bar is provided with internal screw thread, bit shank
Outer ring be provided with external screw thread, the straight knife bar and bit shank by internal screw thread together with externally threaded be connected, simultaneously
The inner ring of the straight knife bar and the inner ring of bit shank are closely withstood on together under the action of outer ring.
Preferably, the force snesor is made by piezoelectric ceramics or piezoelectric sensitivity material.
Preferably, the end of the bit shank is provided with blade.
Preferably, the straight knife bar and bit shank are hollow cylinder.
Preferably, the straight knife bar and bit shank are made by silicon nitride ceramics.
The invention has the advantages that
1, since the straight knife bar and bit shank of the needle knife are made of silicon nitride material, so it has high temperature resistant, antioxygen
Change, the performances such as resistant to chemical etching.Performance due to the ceramics with high-intensity and high-tenacity, therefore the needle knife intensity with higher,
And good toughness is durable.
2, force sensor is arranged in the straight knife bar of the needle knife and bit shank junction, can to the resistance that bit shank is subject into
Row precise measurement.After the processing of data processing module, the different tissues layer of human body can be entered to the edge of a knife of bit shank
It is identified.
3, two layers inside and outside having at the resistance detecting module of needle knife, two parts of outer layer ring are closely fixed on one by screw thread
It rises, two parts of inner layer ring are closely withstood on together under the action of outer layer ring.Under the action of two layers of ring, resistance detecting module
There is good waterproof action, internal sensor can be protected well.

Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, with reference to the accompanying drawings and embodiments to this hair
It is bright to be described in further detail, it should be understood that implementation example described herein is merely to illustrate and explain the present invention, not
For limiting the present invention.
It is provided by the invention a kind of from high-intensitive early warning ceramic pin knife is perceived see Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, it wraps
Include signal lamp 1, data processing module 2, power supply 3, handle 4, straight knife bar 5, signal transmssion line 6, resistance detecting module 7, bit shank
8, voice signal player 9;Signal lamp 1, data processing module 2, power supply 3, voice signal player 9 are arranged in handle 4;
Resistance detecting module 7 is arranged between straight knife bar 5 and bit shank 8;Data processing module 2 passes through signal transmssion line 6 and letter respectively
Signal lamp 1, power supply 3, voice signal player 9 connect;Resistance detecting module 7 is by the end of straight knife bar 5 and the starting point of bit shank 8
Composition;The end of straight knife bar 5 and the starting point of bit shank 8 are provided with outer ring 10 and inner ring 12;Setting is strong in inner ring 12 passes
Sensor 11;Force snesor 11 passes through signal transmssion line 6 and 2 connection communication of data processing module;The outer ring 10 of straight knife bar 5 is provided with
Internal screw thread, the outer ring 10 of bit shank 8 are provided with external screw thread, straight knife bar 5 and bit shank 8 and are connected by internal screw thread and externally threaded occlusion
It is connected together, while the inner ring 12 of straight knife bar 5 and the inner ring 12 of bit shank 8 are closely withstood on together under the action of outer ring.Knife
The resistance that the edge of a knife of head rod end is subject in the traveling process in tissue is measured by force snesor 11, data processing
