Problems solved by technology

According to the various methods available for closing acute gastrointestinal perforation, we have concluded the following conclusions: ①The early methods are low in cost, limited in the treatment site or diameter, and suitable for closure of specific sites or small perforations; ②Currently the latest methods The therapeutic effect of the OTSC system is superior to other closure effects, but the operation is complicated and the price is very expensive, so it is not suitable for promotion and application in hospitals at all levels

Embodiment Construction

[0032] The detailed content of the present invention and its specific implementation will be further described below in conjunction with the accompanying drawings.

[0033] see Figure 1 to Figure 8 As shown, the telescopic clip for sealing wounds of digestive tract lesions of the present invention uses two corresponding hinge shafts on the parallelogram mechanism to connect with two operating cables of the gastroscope respectively, and controls the two hinges through these two operating cables. The relative movement between the shafts realizes the sealing and clamping of the gastrointestinal lesions. It includes four rods 1, and the two ends of the rods 1 are respectively provided with hinge holes. The hinge holes of the two adjacent rods pass through the hinge axis a2 and the hinge axis b3 respectively. , hinge axis c4, and hinge axis d5 are connected to form a parallelogram clip; two corresponding hinge axes b3 and one end of hinge axis d5 on the parallelogram clip are resp...

Abstract

The invention relates to an extensible clamp for closing a lesion wound surface of the digestive tract and belongs to the field of medical apparatuses and instruments. The extensible clamp comprises four rods, wherein two ends of each rod are respectively provided with hinge holes, the hinge holes of every two adjacent rods are connected through hinge pins a, b, c and d respectively to form the parallelogram clamp. One end of each of two corresponding hinge pins b and d on the parallelogram clamp is connected with two operating cables of a gastroscope respectively, and a clamping structure is arranged at the other end of each of the two hinge pins b and d. The hinge pins b and d can perform deviating motions by controlling the two operating cables, and the clamping structure at the other end of each of the two hinge pins b and d is opened. The hinge pins b and d can perform opposite motions by controlling the two operating cables till contact is achieved, and the clamping structure at the other end of each of the two hinge pins b and d is closed to achieve closing of the lesion wound surface of the digestive tract. The diameter of the completely closed wound surface is effectively increased, the effect of effectively pulling mucous membranes on the side of a wound surface opening and at the anus side end can be achieved within the range of 45-135 degrees, and the closing speed is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a telescopic clip for sealing wounds of gastrointestinal lesions. Background technique [0002] With the continuous development of our country's society and economy, people's living standards continue to improve, but at the same time people's life pressure is also increasing, fast-paced lifestyles lead to irregular diets for most people, long-term heavy drinking, etc. As a result, the number of patients with digestive tract tumors in my country has increased year by year in recent years. The carcinogenic factors of gastrointestinal tumors are mainly caused by the unhealthy lifestyle of patients, such as eating too fast, eating irregularly, long-term consumption of high-fat, repeatedly heated food, mildewed food, rough food and irritating food, and drinking a lot of alcohol for a long time Wait. The main symptoms of gastrointestinal tumors are abdominal pain, bloating, stomach disc...
