The ultrasonic knife has the cutting hemostasis effect with high efficiency and low cost, and is widely used in the operation process.

In the clinical use process of the ultrasonic scalpel widely applied to the market at present, along with the operation, the temperature of the metal scalpel bar may exceed 80 ℃ due to the high-frequency friction and oscillation caused by the fact that the scalpel bar continuously cuts tissues, sometimes even reaches 100 ℃, so that non-target tissues, particularly blood vessels, around the scalpel bar are scalded, and irreparable thermal injury is caused. Therefore, when the ultrasonic scalpel is used by a doctor, the doctor has to cool and clean the ultrasonic scalpel in cold saline for a period of time, so that non-target tissues are prevented from being scalded, and the high-temperature scabbing of the scalpel rod is avoided, which undoubtedly brings inconvenience to the use of the ultrasonic scalpel and reduces the operation efficiency of the doctor.

Detailed description of the invention

The present invention is further described in detail with reference to the accompanying drawings and embodiments, and for the purpose of more clearly illustrating the embodiments of the present patent or the technical solutions in the prior art, the drawings required for the embodiments or the prior art descriptions will be briefly introduced below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings may be obtained according to these drawings without creative efforts.

As shown in fig. 1 to 4, an ultrasonic blade system with temperature control includes an ultrasonic blade, a transducer, and a host; the host is provided with a transducer host interface 14, a temperature sensor interface 10, a temperature control display screen 11 and a host control screen 12,

the clamp head consisting of the jaw 3 and the cushion block 4 can be opened and closed by the ultrasonic knife handle to control the clamp head to be closed, and the cushion block 4 is fixed on the jaw 3 and can be used as a protective layer to prevent the knife bar from directly contacting the jaw and damaging the knife bar. The forceps head is driven by an outer sleeve 2 fixed on the handle and a movable inner sleeve 7 to control the movement of the forceps head. The tissue to be cut is clamped between the cushion block and the cutter bar, and when the cutter bar works, the tissue is cut rapidly.

The region of cutter arbor 1 and cushion 4 contact is the centre gripping region, and temperature sensor 5 evenly distributes in non-centre gripping region along the binding clip central line left and right sides, not with cutter arbor direct contact for the temperature gradient distribution condition outside the monitoring cutting region prevents simultaneously that the cutter arbor from damaging temperature sensor during operation. The temperature sensors on one side are arranged in two rows, the distance between the first row and the clamping area is 0.5-1.0mm, and the distance between the 2 nd row and the first row is 1-2 mm; the temperature sensors are distributed along the transverse interval of the clamping area at 3-5mm, the host system processes signals fed back by the temperature sensors, and the temperature is displayed as the highest temperature measured by the temperature sensors, so that when the ultrasonic knife works, the temperature condition around the cut tissue can be monitored in real time, and the cutter bar is prevented from being overheated to scald human tissues.

The temperature sensor 5 is connected to a temperature sensor handle interface 8 on the handle through a temperature sensor line 6; the cutter arbor 1 wears to locate the inner chamber of interior sleeve pipe 7, and the gap between outer tube 2 and interior sleeve pipe 7 is worn to locate by temperature sensor's circuit, and the sleeve pipe carries out relative motion inside and outside the metal, and the space in this gap is enough that temperature sensor circuit 6 does not receive the interference, and temperature sensor 5 is embedded in cushion 4.

The ultrasonic knife is connected with the host machine 13 through the transducer 9, the transducer 9 converts an electric signal provided by the host machine 13 into an ultrasonic signal, and simultaneously transmits the ultrasonic signal to the ultrasonic knife, and through connecting the host machine interface 14 of the transducer, the electric signal generated by the host machine is transmitted to the transducer, the temperature sensor on the clamp head of the ultrasonic knife is connected with the interface 10 of the temperature sensor on the host machine through the handle interface 8 of the temperature sensor on the knife handle, and then the signal collected by the temperature sensor on the clamp head is transmitted to the host machine. The temperature control display screen 11 displays the temperature of the tissues around the ultrasonic cutter bar measured by the ultrasonic cutter bar temperature sensor, and the host control screen 12 can adjust the power gear according to the requirements.

The working mode of the host system is explained, and the host system has two modes, and an operator can adjust the operation according to the operation condition.

The method comprises a first working mode, a constant power mode and a temperature detection mode: as shown in fig. 5, the doctor selects the selection of the system working power on the host control screen 12 on the host display screen, and selects a high-power gear when rapid cutting is required, and the amplitude output by the ultrasonic knife bar is at the maximum position at the time, so that the cutting speed is high, but the thermal damage is large; when the coagulation operation is required, a low-power gear is selected, the amplitude output by the ultrasonic knife bar is reduced, the cutting time is prolonged, but the protein coagulation is sufficient, and the coagulation effect is good. When the ultrasonic scalpel works, the temperature of the cut tissue is sensed by the temperature sensors on the forceps head cushion block, the host system compares and judges the temperature according to the data of the temperature sensors, and the highest temperature signal is directly displayed on the temperature control display screen 11. The operator grasps the heating condition of the cutter bar according to the temperature displayed on the temperature control screen of the host computer, evaluates the thermal damage condition around the cut tissue, and when the judgment temperature is overhigh, the operator can pause excitation or use normal saline to cool and then work again. This mode may provide an effective temperature indication to the operator.

The working mode II is a constant temperature and self-adaptive power mode: as shown in fig. 6, when an operator selects a proper gear to activate, when clamping tissue to cut and stop bleeding, the temperature of the cutter bar rises, the temperature is transmitted to surrounding tissue to cause influence, and the temperature sensor on the forceps head senses the temperature. When the host system monitors data transmitted by each temperature sensor, and when the temperature of any one temperature sensor reaches a threshold value of 100 ℃, the host automatically reduces the power by 20 percent through the control circuit; if the ultrasonic knife continues to work continuously, the temperature of the knife bar can be further increased, thermal damage is successively enlarged, and when the maximum temperature of one temperature sensor is detected to exceed 140 ℃, the power of the main machine is automatically reduced by 40 percent through the control circuit. Thus, when the tissue is continuously cut, the temperature of the cutter bar cannot be too high through temperature monitoring and automatic power adjustment and adaptation, and accidents are prevented.

In addition, it should be noted that the patent is not limited to the above embodiments, as long as the specific size or shape of the components is not described, the components can be any size or shape corresponding to the structure, and no matter any change is made on the material composition, the structural design provided by the invention is a modification of the invention, and should be considered as being within the protection scope of the invention.
