Description

Technical Field

[0001] The invention belongs to the technical field of medical instruments, and in particular relates to a bipolar electrocoagulation forceps with a time-delay switch. Background Art

[0002] The bipolar electrocoagulation forceps device is a medical device for electrocoagulation hemostasis. It is favored by minimally invasive surgery clinicians because of its simple operation, fast coagulation and good coagulation effect. When performing clinical surgery under laparoscopy, although the trauma is small, the operation process will inevitably cut the blood vessels and cause local bleeding. The traditional method of blood blocking with thread ligation is not very applicable in laparoscopic surgery. Therefore, the method of electrocoagulation hemostasis is widely used in clinical practice. The origin of electrocoagulation for surgical hemostasis is very early. The current used for surgery is high-frequency current. High-frequency current can safely pass through the human body even if the voltage is as high as several thousand volts. The thermal effect of high-frequency current is used to dehydrate and shrink the blood vessel wall, coagulate the blood in the blood vessel, and integrate the blood vessel and the blood clot into one, thereby achieving the purpose of effective hemostasis. At present, the bipolar coagulation forceps device in the prior art is mainly composed of a forceps head, a forceps rod, a forceps handle and a high-frequency cable. The opening and closing of the forceps head are manually controlled by the forceps handle to achieve the functions of coagulation and clamping. However, when using the existing bipolar coagulation forceps, some of them are large in size or weight and are inconvenient to carry and use. Moreover, after all, they are electrically conductive bodies. Some reusable coagulation forceps have large heat loss to their insulating parts, which slows down their coagulation speed and worsens the effect.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a bipolar electrocoagulation forceps head with enhanced insulation [201620262696.X], which includes a mounting base with a fork at the front end and a first clamp body and a second clamp body arranged correspondingly, the rear ends of the first clamp body and the second clamp body are both located in the fork, the first clamp body is hinged to the fork, the second clamp body is hinged to the tail of the first clamp body, the tail of the second clamp body is hinged to the pull rod, the pull rod is inserted into the mounting base and can move axially along the mounting base, and a labyrinth insulation structure is provided between the first clamp body and the second clamp body, which is located in the fork and can prevent short circuits during operation.

[0004] The above solution solves the problem that bipolar coagulation forceps are inconvenient to carry and use to a certain extent, but the solution still has some shortcomings. For example, since it enhances the insulation of the forceps head to reduce its heat loss, but because the coagulation forceps are reused, some insulating parts such as the forceps head will inevitably suffer greater heat loss, which will reduce the coagulation speed and effect without being noticed. Summary of the invention

[0005] The purpose of the present invention is to provide a bipolar electrocoagulation forceps with a time-delay switch which has a reasonable design, is lightweight and portable, and has a good electrocoagulation effect in view of the above problems.
