- May 01, 2018 -

FIELD OF THE INVENTION The present invention relates to a surgical instrument, and more particularly to an gynecological electric hysterectomy device for resection of the uterus.


At present, many hospitals in China have undergone laparoscopic hysterectomy. The special surgical instruments used are electric hysterectomy devices. The electric hysterectomy device includes a large grasping forceps, a cutting tube saw and a handle motor, wherein the cutting tube saw is fixedly connected to the handle motor, and the large grasping forceps sleeve is placed in the tube body of the cutting tube saw. The handle motor is provided with a rechargeable battery, a DC motor and a transmission device. The DC motor rotates to drive the cutting tube saw to rotate through the transmission device. Since the edge of the head of the sawing tube is saw-toothed, the removal of the uterus is completed, and then the large clamp is used. Cuts are clipped out of the body. The use of this device has the advantages of less trauma, less patient suffering, and faster postoperative recovery, but due to relying on the rechargeable battery to provide power, if the rechargeable battery is insufficiently charged, or the operation time is too long, the power will be obviously insufficient, and the continuous operation is continued. Sexuality has to have an impact, and this type of hysterectomy device does not have the function of adjusting the rotation speed of the resected tube saw, nor can it be easily opened and closed, which has an impact on the operation of the surgeon.

The purpose of the utility model is to overcome the defects of the prior art and provide a method which can be used continuously and is easy to operate.


An electric hysterectomy device.

The utility model is an electric hysterectomy device realized in this way, which comprises a large grasping forceps, a cutting pipe saw and a handle motor, wherein the cutting pipe saw is arranged on the handle motor and is matched with the transmission seat of the handle motor, and the large grasper clamp The movable sleeve is placed in the tube body of the cutting tube saw, which is characterized in that the handle motor is connected with the DC power controller through a wire, the DC motor in the housing is connected with the gear box, and a set of bevel gears are placed on the upper part of the gear box, one of the umbrellas The gear is fixedly connected with the transmission seat, and the other bevel gear is connected with the gear box through the transmission shaft.


The electric hysterectomy device is characterized in that the handle motor is provided with a transfer switch which can change the rotation direction of the drive seat of the handle motor and a start switch capable of controlling the opening and closing of the direct current motor through the shell.

The electric hysterectomy device is characterized in that the DC power controller includes a casing, a transformer and an AC-DC conversion circuit are arranged in the casing, a speed adjustment switch and a power switch which can change the output power are arranged outside the casing. Meter, two wires lead from the DC power controller, one connected to the AC power supply, one connected to the handle motor.


With this structure, due to the increase of the DC power supply controller, the defect of the insufficient charge of the rechargeable battery is avoided and the continuity of the operation is achieved, and the cutting tube saw can adjust the rotation speed and direction through the speed control switch and the switch and set Turn on the switch to facilitate the operation of the surgery.
