Abstract
The invention provides a spinal cord osteotome. The osteotome comprises a handle, a preamplifier arranged in the middle of the handle, a drill rod connected with the handle, as well as a miniature ultrasonic transducer arranged in the front end of the drill rod of the spinal cord osteotome, wherein the miniature ultrasonic transducer is connected with the preamplifier in the handle by virtue of a shielding signal wire. The spinal cord osteotome detects and judges by virtue of changes of acoustic properties (impedance and phase) of the miniature ultrasonic transducer when the miniature ultrasonic transducer is in different environments and different mediums, so that an alarm signal is sent out in time when the spinal cord osteotome is dislocated, thus a doctor is prompted to adopt timely measures to reduce hurt on a patient.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, the spinal cord osteotome is used in particularly a kind of operation.
Background technology
At present the machine line technology to ultrasound wave in human body bone with human body soft tissue in; Can detect differentiation, for how improving stability and reliability, need be when making sonac; Constantly with the machine line matching and debugging, in the hope of reach to the alarm in the operation stable with reliably.
Patient is being carried out comprise thecal puncture in the operation on spinal cord, spinal cord is beaten in the process of nail; The doctor to the boring of patient's spinal bone the time, with spinal cord osteotome boring commonly used, be experience and sensation; Sometimes can punch spinal bone because of carelessness, and then throw soft tissue into, thereby human body is damaged.
Summary of the invention
In order to solve above-mentioned the problems of the prior art; The present invention proposes a kind of spinal cord osteotome of using as medical apparatus and instruments; Function with ultrasonic interventional therapy; Make the doctor can by rule of thumb and feel not only that in operation it is dangerous whether dislocation takes place in the time of can also knowing operation more intuitively, can more protect patient not receive unexpected injury.
For reaching the object of the invention, novel spinal cord osteotome of the present invention comprises handle, and it is the bakelite or the aluminium alloy ellipsoid of hollow, and is basic identical just as spinal cord osteotome commonly used outward, and in the middle of the handle preposition coupling amplifying circuit is installed; Drilling rod, basic identical just as spinal cord osteotome commonly used outward; Drilling rod from its sonac of installing additional of a distance foremost; And be installed in spinal cord osteotome micro-ultrasonic wave sensor foremost, in order to detect different tissues.Wherein, the setting of front end amplification matching circuit is because sonac is a high impedance, low signal, thus need at the proximity transducer place amplification matching circuit of trying one's best, in order to amplifying signal and reduction impedance.
Preferably, the center of said drilling rod processes a slotted hole to the pick off place, uses shielded signal wire to connect the preposition amplification matching circuit in pick off and the handle.
Preferred again, said shielded signal wire is the ultrathin coaxial cable of 0.4-0.5mm, connects pick off and preposition amplification matching circuit.
Preferred again, said micro-ultrasonic wave sensor is the miniature ultrasonic pick off of 1MHz-5MHz, and overall dimensions is about 0.6 * 3mm.
Preferred again, said spinal cord osteotome also comprises the communication lead, connects host-processor, and power supply is provided, and the transmission signal, and behind the host circuit signal processing, whether decision reports to the police.
Spinal cord osteotome of the present invention, in the time of can judging the boring of spinal cord osteotome effectively, the spinal cord osteotome is in the spinal bone or has punched in the outer soft tissue of bone.In being in the varying environment different medium time, its acoustic characteristic (impedance, phase place) changes and detects judgement according to set miniature ultrasonic pick off, thereby when dislocation takes place the spinal cord osteotome, in time sends alarm signal.
Be specially, because osseous tissue is harder, and human body soft tissue is soft; The ultrasonic transducer of miniature ultrasonic pick off is among both because of sound field is different, and bigger variation can take place the acoustic characteristic of ultrasonic transducer, when osteotome is punched bone; Ultrasonic signal can change, and after front end circuit amplified, main frame just can be told and given the alarm at once; So remind operative doctor, reduce injury by this patient.
Ultrasonic spinal cord osteotome of the present invention when punching the spinal bone certain distance because of carelessness, just can in time send alarm signal, reminds the doctor to note, takes timely measure, reduces the injury to patient.
Description of drawings
Through the detailed description below in conjunction with accompanying drawing, aforesaid purpose, the feature and advantage with other of the present invention will become obvious.Wherein:
Fig. 1 looks cutaway view for the master of novel spinal cord osteotome of the present invention;
Fig. 2 is the side view of novel spinal cord osteotome of the present invention;
Fig. 3 is the partial enlarged drawing of A portion among Fig. 2.
The specific embodiment
Like Fig. 1 and shown in Figure 2; Novel spinal cord osteotome of the present invention comprises handle 2; Pre-amplification circuit 3 is installed in the middle of the handle; The drilling rod 4 that links to each other with handle 2 is equipped with micro-ultrasonic wave sensor 6 in spinal cord osteotome drilling rod 4 foremost, through the pre-amplification circuit 3 in shielded signal wire 5 connection micro-ultrasonic wave sensors 6 and the handle 2.Wherein handle 2 is the bakelite or the aluminium alloy ellipsoid of hollow, and is basic identical just as spinal cord osteotome commonly used outward; Drilling rod 4 outer basic identical just as spinal cord osteotome commonly used; Micro-ultrasonic wave sensor 6 be installed in drilling rod 4 from its a distance foremost, preferred, be installed in apart from its 2 to 3mm places foremost, in order to detect different tissues.Wherein, it is because micro-ultrasonic wave sensor 6 is high impedances that frontend amplifying circuit 3 is set, low signal, thus need at the proximity transducer place amplification matching circuit of trying one's best, in order to amplifying signal and reduction impedance.
Preferably, be processed with a slotted hole 42 to the pick off place at the center of said drilling rod, shielded signal wire 5 is arranged in this slotted hole 42 to connect the pre-amplification circuit 3 in micro-ultrasonic wave sensor 6 and the handle 2.Wherein preferred, said shielded signal wire is the ultrathin coaxial cable of 0.4-0.5mm.
In addition, said micro-ultrasonic wave sensor is the miniature ultrasonic pick off of 1MHz-5MHz, and overall dimensions is about 0.6 * 3mm.
As shown in Figure 3, have graduation mark in the front portion of spinal cord osteotome of the present invention, the degree of depth that osteotome pierces in the time of can making things convenient for the doctor accurately to understand operation.
Preferred again, said spinal cord osteotome also comprises communication lead 1, connects host-processor, and power supply is provided, and the transmission signal, and behind the host circuit signal processing, whether decision reports to the police.
The work process of spinal cord osteotome of the present invention is following, because set miniature ultrasonic pick off 6 is in being in the varying environment different medium time, its acoustic characteristic (impedance, phase place) can change.Because osseous tissue is harder, and human body soft tissue is soft, when the ultrasonic transducer of miniature ultrasonic pick off is among both; Because of sound field is different, bigger variation can take place in the acoustic characteristic of ultrasonic transducer, so when osteotome is punched bone; Ultrasonic signal can change; After front end circuit amplified, main frame just can be told and give the alarm at once and detect judgement, thereby when dislocation takes place the spinal cord osteotome, in time sent alarm signal.So remind operative doctor, reduce injury by this patient.
The present invention is not limited to described embodiment, and those skilled in the art still can do some corrections or change, so rights protection scope of the present invention is as the criterion with claims restricted portion not breaking away from spirit of the present invention promptly openly in the scope.
