Ultrasonic Surgical Equipment {Ultrasound operating apparatus}

The present invention relates to an ultrasonic surgical device that supports the operation of incision, suture, etc. of the affected area by using ultrasonic vibration, more specifically, twisting to prevent twisting of the cable so that the power supply cable is twisted during surgery. It is equipped with a prevention connector, and it is equipped with a detachable means for easy replacement by easy detachability when the surgical device needs to be replaced due to a change in the surgical site or a change of the procedure during the operation, and the power is automatically turned on when the cable is disconnected for replacement. It is equipped with automatic power on / off means to ensure electrical safety in case of damage and replacement work by no-load driving, and it can be easily adjusted directly in the ultrasonic surgery machine without the need to operate the main equipment supplying high frequency power to control the intensity of ultrasonic waves. Ultrasonic power control means so that the other high frequency When used in combination with electrosurgical instruments and surgery, insulation disks are provided on the ultrasonic wave generation module so that the main equipment is not damaged or leakage current is not applied to the patient. A heat dissipation means for quickly discharging the internal heat to the outside, and having an operation unit for allowing the affected part to be operated more accurately and conveniently, and an operation unit for the operator to operate the operation unit more conveniently. It is about.

The overall time for internal medicine or surgical operation varies according to the type of surgery such as cutting, excision, extraction, fixation, etc., but it takes a lot of time and effort to reseal the tissue after completion of treatment.

In the case of surgery for cutting the extremities, most of the time after fixing the bones, most of the time to suture the muscles, tendons, nerves, blood and the joints are spent.

In this operation, conventional sutures and needles or various types of suture staplers may be used.

However, depending on the biological tissue, a lot of effort is required when using the existing sutures and needles, or it may be difficult to apply a stapler for sutures.

In the case of narrow tubules, blood, and nerves, the support of the tissues is weak.

Ultrasonic surgical instruments are used to easily penetrate the tissue by vibrating the needle with ultrasound in order to facilitate suture using the suture and the needle under such various surgical environments.

Some ultrasonic surgical instruments are provided with a function of adjusting the ultrasonic intensity, which is a mechanical switch or a variable resistance type structure, which is vulnerable to erosion of the corrosive disinfectant solution, which frequently causes a problem.

In addition, the ultrasonic wave generating module for generating ultrasonic waves is composed of a piezoceramic laminated body in which a plurality of piezoelectric ceramic plates (PZT) are stacked, and a delivery horn which delivers ultrasonic waves generated in the piezoelectric ceramic laminated body to the procedure unit. It is not insulated by piezoceramic laminate and transfer horn. Usually, there is no big problem because the transmission horn is grounded, but when used in combination with other high frequency electrosurgical instruments during surgery, there is a risk of damaging the main equipment or applying leakage current to the patient.

The present invention has been made in order to solve the problem that the ultrasonic surgical device according to the prior art as described above,

The cable supplying power during the operation is twisted so that there is no inconvenience in the procedure, and when the ultrasonic surgery machine needs to be replaced, it can be easily detached and replaced, and the power is automatically cut off when the cable is removed for replacement. It secures electrical safety during damage and replacement work, and can easily adjust the intensity of the ultrasonic wave directly in the ultrasonic surgery machine, and the main equipment is damaged or leakage current is applied to the patient when used in combination with other high frequency electrosurgical surgery. The internal temperature is increased by long time use, and the internal heat is released to the outside quickly to prevent problems such as output degradation.The treatment of the affected area is more accurate and convenient, and the operator can use the treatment unit more conveniently.

When the movable handle C13 is pressed toward the fixed handle C12, that is, when the movable handle C13 is moved forward, the force is transmitted to the rotary arm C9 through the rotary shaft C8, and the operation rod C1. ) Moves forward, and the operating rod (C1) to move forward the forward and backward piston (D7), and the crank bar (D6) to the rear of the movable jaw (D2) as the forward and backward piston (D7) advances. The movable jaw D2, which was lifted up and shut, moves away from the fixed jaw D1 to open the mouth.

Insert the procedure needle into the open jaw (D2) and the fixed jaw (D1) with open mouth, and move the movable handle (C13), crank bar (D6) while the front and rear dermis (D7) is reversed by the restoring spring (D5) Pulls the rear of the movable jaw D2 down to close the open mouth, and simultaneously moves the movable handle C13 to the neutral position by reversing with the operation rod C1 by the neutral spring C3.

When the movable jaw D2 and the fixed jaw D1 want to bite the needle more strongly, when the movable handle C13 is reversed, the operation rod C1 retreats in the opposite operation above, and accordingly As the piston D7 moves backward, the movable jaw D2 moves further toward the fixed jaw D1 to bite the needle more strongly.
