The invention relates to a multifunctional shaver for laparoscopic surgery. The multifunctional shaver comprises a handle assembly and a tool holder assembly, wherein the handle assembly pulls a tension rod by a handle; the tension rod pulls the tool holder assembly; a rotary wheel drives the tension rod and the tool holder assembly to rotate by 360 degrees; and the tool holder assembly provides high-frequency electric energy to tissues inside the body by taking a movable tool holder and a fixed tool holder as bipolar two ends, thereby carrying out such surgeries as electrocoagulation, incision, traction and separation. The multifunctional shaver is integrated with a plurality of important functions to carry out bipolar electric incision, bipolar electrocoagulation on the same surgical instrument, and grasp and pull tissues and fine split tissues like a common laparoscopic surgery, so that great convenience is provided for a doctor, surgical time is shortened, and a problem that the doctor frequently changes surgical instruments in the laparoscopic surgery is solved.

The invention discloses a pair of portable non-stick bipolar electrocoagulation forceps. The portable non-stick bipolar electrocoagulation forceps comprise a gun type forceps seat, two linear type conductive electrodes and a high-temperature-resistant and insulated heat-shrinkable sleeve, wherein the gun type forceps seat is made of a plastic material, the linear type conductive electrodes are made of metal materials, a symmetric placing groove is arranged at an inner side between the conductive electrodes, an outer infusion tube is arranged in the placing groove, and is used for outputting rinsing water at free ends of the conductive electrodes, and the heat-shrinkable sleeve is firmly sleeved at the outer side of a whole composed by the conductive electrodes and the outer infusion tube, but exposes the tail end of the placing groove and the free ends of the conductive electrodes. The portable non-stick bipolar electrocoagulation forceps have the beneficial effects that: material consumption is reduced on the basis that product safety is ensured, and production efficiency is increased, so that medical cost is reduced, and market competitiveness of the product is greatly improved; and moreover the portable non-stick bipolar electrocoagulation forceps are convenient and safe to use, and are flexible to operate, so that working efficiency is effectively ensured.

The invention discloses a neurosurgical electrocoagulation and electrocision tool, which belongs to the technical field of neurosurgical minimally invasive surgery instruments and comprises a pair ofbipolar electrocoagulation scissors, a pair of bipolar electrocoagulation pathology forceps, a pair of bipolar electrocoagulation forceps, a pair of bipolar electrocoagulation biting and cutting forceps, a single-head electrocoagulation knife and a single-pole drip aspirator. The structure of the bipolar electrocoagulation scissors is as follow: the clamping rod is hollow, one end of the clampingrod is conical, the other end of the clamping rod is round, two corresponding guide rods are installed in the clamping rod, blades are arranged at the corresponding front ends of the guide rods, a first water pipe is arranged between the two guide rods, a beam tube is installed outside the two guide rods in the clamping rod, the rear end of the beam tube is connected with a push rod, and the tailend of the push rod is fixedly connected with the upper end of a first handle through a nut; the first handle is hinged with a second handle, the rear end of the clamping rod is fixedly connected to the upper end of the second handle; the rear end of the guide rod is connected with a conduction wire, the rear end of the first water pipe is connected with a first water pipe connector. An adapters is fixedly mounted on the outer side of the clamping rod through clamp; due to single-pole head end and the double-pole head end with various shapes and styles, the angle and the length can be adjusted, and no operation dead angle exists in a narrow operation field.
