Description

Soft lens multifunction supersonic knife

Technical field

The utility model relates to a kind of medical instruments, more particularly, to soft lens multifunction supersonic knife.

Background technique

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 mainly includes supersonic signal generator, function Rate amplifier and embedded computer.The small-power ultrasound electric signal that supersonic signal generator generates amplifies through power amplifier It afterwards, can ultrasonic transducer work 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 Surgical knife tool is transmitted to after amplitude transformer realizes Amplitude amplification at ultrasonic mechanical wave.

But although ultra-sonic surgical aspirator has the above advantages, which are mainly applied under rigid pipe endoscope guidance now Minimally Invasive Surgery, current medical soft lens (such as nasal endoscopes, laryngoscope, bronchoscope or digestive endoscopy etc.) mainly uses high-frequency electrical Knife, and electric knife can not be stopped blooding and be cut simultaneously in the course of surgery, especially damage blood vessel causes bleeding to be difficult to control System, so that needing to take other modus operandis, such as laparoscope or abdominal.Although ultrasound knife is by converting electrical energy into machinery Can, it is vibrated with 20~60kHz ultrasound high frequency, makes to contact histocyte water vapor, albumen hydrogen bond fracture, after tissue is solidified It cuts, can be realized simultaneously hemostasis and cutting, accelerate operative speed.Compared with traditional electric knife, ultrasound knife have amount of bleeding it is few, Reduce EFFECTS OF HEATING DAMAGE ON, the formation of less smog, act on without nervimuscular electro photoluminescence, improve resection rate, reduce complication etc. Plurality of advantages.But current ultrasound knife the shortcomings that there are diameters is excessively thick, inflexibility, thus it is dfficult to apply to flexible soft lens On.

Utility model content

The purpose of this utility model is exactly to provide soft lens with multi-functional to overcome the problems of the above-mentioned prior art Ultrasound knife.

The purpose of this utility model can be achieved through the following technical solutions: soft lens multifunction supersonic knife, the ultrasound Knife matches use with medical soft lens, which is characterized in that including control terminal, flexible shaft and ultrasonic cutter head, the control terminal Ultrasonic cutter head is connected by flexible shaft.

The medical soft lens is flexible medical endoscope, including nasal endoscopes, laryngoscope, bronchoscope or digestive endoscopy, Flexible shaft and ultrasonic cutter head are entered by the pincers road junction of medical soft lens, along pincers deferent axially into operating cavity.

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 10cm~230cm.

The flexible shaft is flexible tungsten wire hose, and the flexibility tungsten wire inside hose is equipped with PET coating.

The control terminal is connect by the control route being placed in flexible shaft with ultrasonic cutter head.

Sequentially connected frequency converter, conductive pottery, rack and mounting are equipped with inside the control terminal.

Excitation solidifying key and excitation slow hardening key fastly 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 utility model material excellent using softness, oil resistivity, low-temperature shrink, gas barrier property Flexible shaft is made, for connecting and fixing ultrasonic cutter head, the control route of ultrasonic cutter head and control terminal can be placed in the bendable It in crank rod, on the one hand can reduce the size, on the other hand length can be accomplished to 2.3m or so, solve current ultrasonic knife and exist directly Diameter is excessively thick, inflexibility, it is difficult to applied to the problem on flexible soft lens.It can be used for nasal endoscopes, laryngoscope, bronchoscope and digestion On the flexible endoscope of the wider scope such as scope, have a wide range of application.
