Description

Technical Field

[0001] The present invention relates to the technical field of surgical devices, and in particular to a high-efficiency electric coagulation and electric cutting bipolar electric coagulation forceps. Background Art

[0002] Electrocoagulation forceps is one of the commonly used medical devices in surgical operations. It is used for electrocoagulation hemostasis and electrocuting operations on tissues. It uses high-frequency electric current to generate a thermal effect, quickly coagulating tissue to achieve hemostasis. At the same time, it can also cut tissue to reduce operation time. Compared with traditional surgical forceps or other hemostasis measures, electrocoagulation forceps can quickly coagulate blood vessels and stop bleeding, avoiding the need for suturing and other steps in traditional operations, reducing operation time and surgical trauma. In addition, electrocoagulation forceps can also reduce the amount of incision bleeding, reduce the incidence of postoperative infection and complications, and improve the safety and effectiveness of the surgical process.

[0003] However, most of the existing electrocoagulation forceps are designed with an integral toothed structure, and the toothed jaws are designed to enhance the gripping force. When clamping tissue, the integral toothed electrocoagulation forceps are likely to cause unnecessary damage to the patient's tissue, making the tissue easily adhere to the alveolar cavity, resulting in eschar shedding and bleeding, and even causing tissue tearing, affecting the surgical effect and the patient's postoperative recovery. At the same time, the toothed structure of the electrocoagulation forceps is likely to hinder smooth movement during the cutting process, resulting in a slower cutting process during surgery, which increases the operation time. In addition, the electrocoagulation area of ​​the toothed structure is relatively dispersed, which reduces the density of the electrocoagulation forceps' output energy and may also cause unnecessary thermal damage to the surrounding normal tissues. Therefore, there is an urgent need for a high-efficiency electrocoagulation and electrocuting bipolar coagulation forceps to solve the above problems. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and provide a high-efficiency electrocoagulation and electrocuting bipolar coagulation forceps, which has both high-efficiency electrocoagulation and hemostasis and precise electrocuting functions, and can better avoid tissue adhesion.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: A high-efficiency bipolar electrocoagulation and electrocuting forceps comprises a handle and a grip hinged to each other, the grip being connected to the forceps head via a connecting rod group, the forceps head comprising a first forceps head and a second forceps head that cooperate with each other, the first forceps head and the second forceps head being able to open and close by adjusting the grip, the working end surfaces of the first forceps head and the second forceps head being smooth contact surfaces without teeth, a cutting rib being provided on the end of the first forceps head, and a cutting groove that cooperates with the cutting rib being provided on the end of the second forceps head.

[0006] The inner surface of the forceps head is the working end face, which is designed as a smooth contact surface structure without teeth. During the electrocoagulation process, the high temperature of the forceps head will cause the tissue protein to denature and carbonize, which is very easy to adhere to the working surface of the forceps head, making the forceps head difficult to open and requiring frequent cleaning. At the same time, if it is forcibly opened after electrocoagulation, it may tear the tissue and cause secondary damage to the patient's surgical site. The structural design of the smooth contact surface greatly reduces the tissue attachment area and embedment point, significantly reduces the occurrence of adhesion, reduces the time of pauses for cleaning, makes the surgical operation smoother, and greatly improves the surgical efficiency, and reduces the risk of secondary damage due to tissue adhesion. The smooth contact surface can also form a more uniform pressure with the tissue. This pressure distribution helps to more effectively close the blood vessel wall, thereby producing a more reliable coagulation effect; the cutting ribs and cutting grooves set at the end of the forceps head work together, so that the forceps head without teeth can also achieve electrocoagulation and electrocuting functions on blood vessels or tissues.

The cutting ribs and cutting grooves are arranged at the tip of the pliers head, away from the working body of the smooth contact surface, which effectively limits the cutting function to the end area, so that the working smooth contact surface can focus on providing the best electrocoagulation function without being affected by the cutting part, thereby significantly improving the reliability of the operation; at the same time, the cutting ribs and cutting grooves arranged on the smooth contact surface can provide sufficient anti-slip force for the pliers head, so that the toothless pliers head can also provide the anti-slip force possessed by the toothed pliers head when working.
