Abstract

The invention discloses a high-strength high-toughness self-sensing intelligent ceramic needle knife, which comprises six signal lamps, a data processing module, a power supply, a handle, a straight knife bar, a signal transmission wire, a resistance detection module and a tool bit bar, wherein the resistance detection module is arranged between the straight knife bar and the tool bit bar; a force sensor is arranged inside the resistance detection module; the six signal lamps respectively represent that a knife edge at the end part of the knife head bar enters different tissue layers of the human body. The resistance received by the knife edge at the end part of the knife head bar in the advancing process in the human body tissues is measured by the force sensor; data measured by the force sensor is transmitted to the data processing module by the signal transmission wire; after the data is processed by the data processing module, the corresponding signal lamps are controlled to be turned on. Therefore the self-sensing intellectualization of the needle knife control is realized; the problem of treatment accident occurrence due to experience lack of some doctors is solved.

Description

A kind of high-intensity high-tenacity is from perception intelligent ceramic pin knife
Technical field

Background technology
Pin knife used by Hospitals at Present is small needle knife, and it is made up of three parts, respectively handle, straight knife bar and bit shank. Straight knife bar and bit shank material therefor are steel.But pin knife is often and bioresorbable, is easily corroded.Straight knife bar is thinner, directly Footpath is generally less than 3mm, easy brittle failure.
Also has now another pin knife, its end carries endoscope, huge visual equipment and analysis in addition Software.On the one hand, because this pin knife is excessively huge it is impossible to keep the flexibility of pin knife.On the other hand, visualization device with point Analysis software substantially lags behind the process of the operation hour hands knife edge of a knife, and the time requirement to operation is unfavorable, brings misery to patient, impact Treatment, pin knife doctor does not accept this technology very much.
Content of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of high-intensity high-tenacity is from perception intelligent ceramic pin knife.
The technical solution adopted in the present invention is:A kind of high-intensity high-tenacity exists from perceiving intelligent ceramic pin knife, its feature In:Including signal lamp, data processing module, power supply, handle, straight knife bar, signal transmssion line, resistance detecting module, bit shank;Institute State signal lamp, data processing module, power supply are each provided in described handle;Described resistance detecting module is arranged on described straight knife bar And bit shank between;Described power supply is connected with data processing module;Described resistance detecting module passes through signal transmssion line and data Processing modules implement communicates;Described data processing module and signal lamp are attached by wire, for lighting of control signal lamp With extinguishing.
Preferably, described resistance detecting module is made up of the end of straight knife bar and the initiating terminal of bit shank;Described straight knife The initiating terminal of the end of bar and bit shank is provided with outer shroud and inner ring;Setting force sensor in described inner ring;Described power passes Sensor passes through signal transmssion line and data processing module connection communication;The outer shroud of described straight knife bar is provided with internal thread, bit shank Outer shroud be provided with external screw thread, described straight knife bar and bit shank pass through internal thread together with externally threaded being connected, simultaneously Together with the described inner ring of straight knife bar closely withstands in the presence of outer shroud with the inner ring of bit shank.
Preferably, described force snesor is made by piezoelectric ceramics or piezoelectric sensitivity material.
Preferably, described signal lamp has 6, when the edge of a knife on described bit shank sequentially enters the subcutaneous fat of tissue When fat, manadesma, muscle, ligament, capsular ligament, bone, 6 signal lamps will be fired in sequence.
Preferably, described straight knife bar and bit shank are hollow cylinder.
Preferably, described straight knife bar and bit shank are made by silicon nitride ceramics.
A kind of high-intensity high-tenacity of the present invention from perceive intelligent ceramic pin knife advantage be:
1st, because the straight knife bar of this pin knife and bit shank are made by silicon nitride material, thus it have high temperature resistant, anti-oxidant, resistance to The performances such as chemical attack.Because this pottery has the performance of high-intensity high-tenacity, therefore this pin cutter has higher intensity, and tough Property is good, durable in use.
2nd, the straight knife bar of this pin knife and bit shank junction setting force sensor, can enter to the resistance that bit shank is subject to Row accurate measurement.After the process of data processing module, the edge of a knife of bit shank can be entered into the specific tissue layers of human body It is identified.
3rd, there is inside and outside two-layer at the resistance detecting module of pin knife, two parts of outer layer ring are closely fixed on one by screw thread Rise, two parts of inner layer ring closely withstand on together in the presence of outer layer ring.In the presence of two-layer ring, resistance detecting module There is good waterproof action, internal sensor can be protected well.
