Description
Technical field
The present invention relates to a kind of medical instruments, more particularly, to a kind of digestive endoscopy ultrasound knife device.
Background technology
With the rapid development of modern medicine, ultra-sonic surgical aspirator has been increasingly being applied in disease treatment, it will surpass
Acoustic energy is applied to operation, and the feature protruded is to cut fine, safety, tissue selectivity and low temperature hemostasis etc., greatly rich
The rich means of operation, improve the quality of operation, alleviate the slight illness of patient to a certain extent.Conventional ultrasonic cut hemostasis
The system of instrument is mainly made of host, handle, cutter and floor push.Wherein host includes mainly supersonic signal generator, work(
Rate amplifier and embedded computer.The small-power ultrasound electric signal that supersonic signal generator generates amplifies through power amplifier
Afterwards, ultrasonic transducer work that can be in driving handle；Embedded computer is mainly responsible for coordination and control complete machine work, receives control
System instruction, display instrument working condition realize the functions such as human-computer interaction and foot-operated control.In addition embedded computer will also be completed
To ultrasonic transducer automatic frequency tracking function.Handle includes ultrasonic transducer and amplitude transformer, and completion converts ultrasonic electric signal
At ultrasonic mechanical wave surgical knife tool is transmitted to after amplitude transformer realizes Amplitude amplification.
But although ultra-sonic surgical aspirator has the advantages that above-mentioned, present main application is under rigid pipe endoscope guiding
Minimally Invasive Surgery, at present digestive endoscopy (such as gastroscope, colonoscopy, enteroscope, duodenoscope etc.) mainly use electric knife, and
Electric knife can not be carried out at the same time hemostasis and cutting in the course of surgery, and especially damaging blood vessel causes bleeding to be difficult to control, with
Cause needs to take other modus operandis, such as laparoscope or abdominal.Although ultrasound knife by converting electrical energy into mechanical energy, with
20~60kHz ultrasound high frequencies are vibrated, and contact histocyte water vapor, the fracture of albumen hydrogen bond, tissue is made to be cut after being solidified,
Hemostasis and cutting are can be realized simultaneously, operative speed is accelerated.Compared with traditional electric knife, ultrasound knife is few with amount of bleeding, reduces
EFFECTS OF HEATING DAMAGE ON, less smog form, are many without nervimuscular electro photoluminescence effect, raising resection rate, reduction complication etc.
Advantage.But current ultrasound knife the shortcomings that there are diameters is excessively thick, inflexibility, thus be dfficult to apply to peep in flexible digestion
On mirror.
Invention content
It uses and surpasses it is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of digestive endoscopy
Sound knife system.
The purpose of the present invention can be achieved through the following technical solutions：A kind of digestive endoscopy ultrasound knife device, it is special
Sign is, including ultrasound knife cannula body and control terminal connected to it, and the ultrasound knife cannula body includes ultrasonic cutter head
With flexible shaft, flexible shaft one end connects control terminal, the ultrasonic cutter head of other end connection；In use, ultrasound knife intubation master
Body is entered by the pincers road junction of digestive endoscopy, along pincers deferent axially into operating cavity.
The diameter of the flexible shaft and ultrasonic cutter head is less than the internal diameter of pincers deferent.
The flexible shaft is made of the excellent material of softness, oil resistivity, low-temperature shrink, gas barrier property.
The material of the flexible shaft includes soft flame retardant polyfurolresin or polyester.
The length of the flexible shaft is 1.5m~2.3m.
The flexible shaft is flexible tungsten filament hose, and the flexibility tungsten filament inside hose is equipped with PET coatings.
The control terminal is connect by the control circuit being placed in flexible shaft with ultrasonic cutter head.
The control terminal is internally provided with frequency converter, conductive pottery, rack and mounting connected in sequence.
Excitation solidifying key and excitation slow hardening key soon are equipped with outside the control terminal.
The ultrasonic cutter head includes bipolar electric knife, elastic separating plier, nipper, Clip Applier, scissors or blood coagulation device.
Compared with prior art, the present invention is made of the excellent material of softness, oil resistivity, low-temperature shrink, gas barrier property
Flexible shaft, for connecting and fixing ultrasonic cutter head, the control circuit of ultrasonic cutter head and control terminal can be placed in the flexible shaft
It in bar, on the one hand can reduce the size, on the other hand length can be accomplished to 1.5m or more, solving current ultrasonic knife, there are diameter mistakes
Slightly, inflexibility, it is difficult to the problem being applied on flexible digestive endoscopy.
