Problems solved by technology

At present, there is laparoscopic equipment that can remove smoke in time, but it is not compatible with the laparoscopic equipment widely used in China at present, and a special insufflation machine must be used, which is expensive and has no promotion value
Although some electrocoagulators have suction function, the suction and coagulation are not carried out simultaneously, not only the smoking efficiency is low, the pneumoperitoneum loss is large, but also the smoking and electrocoagulation are divided into two actions, which is inconvenient to operate

Embodiment 1

[0016] Referring to Fig. 1, Fig. 2 and Fig. 3, a laparoscopic electrocoagulator with synchronous smoking function is composed of electrocoagulation hook 1, insulating tube 2, metal suction tube 3, suction tube sheath 4, and electric cutting button connected in sequence 5. Electrocoagulation button 6, metal shrapnel 7, circuit board 8, synchronous air valve 9, handle 10, independent air valve 11, and flexible ribbed tube 12. The electrocoagulation hook 1 is connected with the metal suction tube 3, the insulating tube 2 is wrapped in the outer layer of the metal suction tube 3, the electrocoagulation hook 1 is arranged in the metal suction tube 3, and the suction tube sheath 4 is wrapped in the metal suction tube 3, the metal suction tube 3 is closely connected to the front end interface of the synchronous air valve 9, the buttons 5 and 6 are connected to the metal shrapnel 7, the metal shrapnel 7 is installed on the circuit board 8, and the synchronous air valve 9 is installed o...

Embodiment 2

[0019] The implementation process of the laparoscopic synchronous smoking hook electrocoagulator of the present invention:

[0020] An electrocoagulator with synchronous smoking function, the suction tube and the electrocoagulator are integrated, the suction port is connected to the electrocoagulation hook, and the suction function is activated synchronously when the electrocoagulation is started, and the smoke generated by the electrocoagulation is sucked into the closed suction system , when the coagulation is turned off, the suction function is also turned off synchronously. Since the smoke is generated during the tissue electrocoagulation process, it is only generated in the area where the electrocoagulation hook touches the tissue. Using this device can immediately suck the smoke away when it is generated, so as to avoid the smoke from spreading to the entire abdominal cavity and affect the field of vision. The exhaust volume is very small, which will not cause a rapid dr...

Abstract

The electrocoagulator with synchronous smoke sucking function with laparoscope operation consists of electrocoagulating hook, insulating pipe, sucking metal pipe, sucking pipe sheath, electrical exsecting button, electric coagulating button, elastic metal sheet, circuit board, sync valve, handle, independent valve and flexible corrugated pipe connected successively. During laparoscope operation, the electrocoagulator can suck out smoke once it is generated to maintain clear operational view field. The present invention is compatible with available laparoscope equipment and operational condition.

Description

technical field [0001] The invention belongs to medical equipment, and relates to a synchronous smoking hook electrocoagulator for laparoscopy with synchronous control circuit and air valve closure. Background technique [0002] Laparoscopic technology is a very rapidly developing field in modern surgery, and laparoscopic surgery has replaced many traditional laparotomy. Electrocoagulator is a commonly used instrument in laparoscopic surgery. The current electrocoagulator will produce a lot of smoke when it is working, which often seriously interferes with the field of vision, making it difficult to perform the operation. The smoke must be exhausted to continue, and the smoke exhaust will cause rapid pneumoperitoneum pressure. The decline will force the operation to be interrupted, which will not only prolong the operation time and increase the risk of the patient, but also the smoke discharged from the body will cause serious harm to the medical staff. How to discharge smo...
