Push-pull type digestive system minimally invasive surgery haemostatic forceps

Abstract

The invention relates to a surgery medical instrument, in particular to a push-pull type digestive system minimally invasive surgery haemostatic forceps which is large in the occlusion force, simple in operation and free of transverse displacement. The forceps comprises a forceps head (1) and a forceps body (2), a cavity is formed by the interior of the forceps body (2), the forceps head (1) is connected with the front end of the forceps body (2) through a rotating shaft (3), end sockets arranged in the forceps body (2) are in a hinged connection with connecting rods (4) respectively, free ends of two connecting rods (4) are in the hinged connection with a transmission bar (5) together, a gear rack is arranged on one side of the transmission bar (5), the transmission bar (5) is connected with a push rod (7) through a steering gear (6), one side of the push rod (7) is provided with a gear rack, and one end of the push rod (7), which is far from the forceps head (1), extends out of the forceps body (2). By means of the connection of the connecting rods (4), the transmission bar (5), the steering gear (6) and the push rod (7), the vertical movement of the push rod (7) is converted to the chelation of the forceps head (1). The push-pull type digestive system minimally invasive surgery haemostatic forceps has the advantages that the design is reasonable, the structure is exquisite, the forceps clamping is stable, the usage is convenient, the required space of the operation is small, and the operation is flexible.

Description

technical field [0001] The invention relates to a surgical medical device, in particular to a push-pull type digestive system minimally invasive surgical hemostatic forceps. Background technique [0002] The digestive system is a very important system among the eight major systems of the human body. It is the only way for human beings to obtain energy through digestion and absorption. Therefore, when there is a disease in the digestive system, it must be treated in time. The digestive system consists of two parts, the alimentary canal and the digestive glands. The alimentary canal is a long muscular tube that starts from the oral cavity and continues to the pharynx, esophagus, stomach, small intestine, large intestine, and finally the anus, including the oral cavity, pharynx, esophagus, stomach, small intestine (duodenum, jejunum, ileum) and Large intestine (cecum, colon, rectum) and other parts. There are two types of digestive glands: small digestive glands and large dig...

AI Technical Summary

Problems solved by technology

Some serious symptoms, such as gastrointestinal bleeding, mechanical obstruction, calculus, endometrial inflammation, etc., all require surgical treatment. The existing technology mostly uses minimally invasive surgery, which has less trauma and faster recovery compared with traditional surgical effects , but the instruments used in the existing minimally invasive surgery, except for the endoscope, electric knife, hot knife, etc., other hemostatic forceps still use the instruments of traditional surgery. The strength is exchanged for the distance, so the lateral displacement is large, and the hemostatic effect cannot be guaranteed if the displacement is reduced, and it cannot meet the requirements of minimally invasive surgery
