Description
Technical Field
The present invention relates to medical equipment, and is especially one kind of electrosurgical device for stopping bleeding and cutting tissue in surgical operation.
Background
Cutting and hemostasis are important steps in surgery. Modern medicine has numerous cutting methods and hemostatic techniques, but still fails to meet clinical needs. For example, electrosurgical technology has evolved from cold blade technology to improve efficiency and reduce trauma. The most common electrosurgical devices are high-frequency monopolar electrosurgical and bipolar coagulation forceps, which are designed to generate high-frequency high-density current through the surgical site where the electrodes contact, thereby causing tissue to undergo high-temperature vaporization, cutting and thermal coagulation for hemostasis. The monopolar high-frequency electrotome is the earliest electrosurgical instrument, and can seal small blood vessels during the tissue cutting process to achieve the purposes of cutting and hemostasis. Because electric sparks can occur during use (high-frequency high-voltage current discharges between an electrode and a tissue to generate high-temperature plasma electric arc light), a large amount of harmful gas can be generated by high-temperature vaporization of the tissue. In order to solve the problem, a part of high-frequency electric knives are designed with a suction pipeline to suck and remove smoke. For example, the patent application of the Chinese utility model: a ladder-type smoking high-frequency surgical electrotome (application number: 201120069060), a tube-type smoking high-frequency surgical electrotome (application number: 201120039629) and an electrotome with a suction function (application number 201120356393). When the high-frequency electrotome is applied to operations at different parts, different requirements are met, for example, the open operation of a superficial part is carried out, the common high-frequency electrotome can meet the requirements, and a better effect can be obtained by adding the suction tube to suck smoke. If surgery is to be performed on a relatively delicate site, it may be necessary to use a more delicate cutting head, or even a needle-shaped cutting head. If the operation is performed deeper in a narrow part, such as the operation under a cavity mirror or the operation in a sinus cavity pipeline, the cutter head needs to be thinner, longer and more pointed, and the insulation protection needs to be good. For example, the patent application of the Chinese utility model: tubular synchronous suction electrocoagulator (application No. 201420502153), high temperature resistant unipolar electrocoagulator (application No. 201220085115) with suction function. Different annular cutter heads are more suitable for special parts such as cervix, bladder, prostate and throat parts. For example, the patent application of the Chinese utility model: safe transurethral bladder tumor electrocision ring (application No. 201120405990), laparoscopic electrocision ring (application No. 201320018172) and needle-like electrocision ring (application No. 201120439375). In addition, when a relatively thick blood vessel or a relatively large hemorrhage occurs in the operation process, the conventional cutter head is difficult to stop bleeding, and special hemostasis equipment such as double-stroke electrocoagulation and the like is needed. The electric coagulation suction tube with suction is clinically practical, can suck hematocele and secretion at bleeding parts, and can be used for accurately stopping bleeding by electric coagulation when a bleeding point is seen clearly. The electric coagulation suction tube has various specifications and models at present, but the common defect is that the working end and the cutter head of the electric coagulation suction tube are easy to scab and adhere when in use, so that the hemostatic effect is poor. The front end of the conventional electrocoagulation suction pipe is provided with an annular opening, the contact surface of an electrode and tissues at a bleeding part is small, and the hemostasis effect is poor. The edge of the annular opening is easy to contact the non-bleeding part, and side damage is caused. One problem often encountered during the operation using electrosurgical instruments is that the cutting head is used for cutting, and when bleeding is obvious, the electrocoagulation suction tube with suction is replaced, so that the operation process is affected by the time consumed for replacing the cutting head and the suction tube. In order to solve the problems, improve the blood vessel sealing function of the electric coagulation suction pipe, prevent eschar adhesion, enhance the hemostatic effect and quickly change the mode into a tissue cutting mode, the invention carries out the following solution.
