Hernia repair patch and lead-in device for hernia repair patch

Abstract

The invention provides a hernia repair patch for repairing inguinal hernia and a lead-in device for the hernia repair patch. The hernia repair patch is rectangular, and the four corners of the hernia repair patch are in a circular arc shape. The edges of the hernia repair patch are bended and bonded to form a guiding expansion wire passage. The four sides and the four circular-arc-shaped corners of the hernia repair patch are correspondingly provided with notches. The lead-in device for the hernia repair patch is composed of a conversion sheath and a guiding expansion wire which is sleeved with the conversion sheath. The hernia repair patch and the lead-in device for the hernia repair patch have the advantages that the hernia repair patch can fully and conveniently move in the preperitoneal space, the hernia repair patch is pushed out of a sleeve of the conversion sheath and directly reaches the symphysis pubis position, the guiding expansion wire is pulled out of the guiding expansion wire passage from the edges of the hernia repair patch after the hernia repair patch is placed at a proper position, the hernia repair patch naturally expands in the preperitoneal space, and then laparoscopic hernia conventional treatment is conducted. The hernia repair patch can be placed at the proper position and accurately positioned under a laparoscope in the operating process, so that the operation time is shortened, and the pains of patients are reduced.

Description

technical field [0001] The invention belongs to a hernia patch and its introduction device, in particular to a hernia patch and its introduction device for laparoscopic hernia repair. Background technique [0002] Inguinal hernia is a common and frequently-occurring disease in surgery. According to incomplete statistics, there are more than 200,000 cases of tension-free hernia surgery in China every year, and the number of operations is increasing year by year. As the development direction of surgery, laparoscopic surgery has the advantages of small wound, small pain, and easy recovery. Fast is a surgical project that has developed rapidly in recent years. However, most of the laparoscopic hernia meshes on the market are made by foreign companies. For example, Bard’s 3D-MAX mesh itself has good plasticity and is easy to use. However, the current domestic production process is difficult to achieve, and the product price is high, so it is difficult to promote it in primary hos...

Problems solved by technology

However, most of the laparoscopic hernia meshes on the market are made by foreign companies. For example, Bard’s 3D-MAX mesh itself has good plasticity and is easy to use. However, the current domestic production process is difficult to achieve, and the product price is high, so it is difficult to promote it in primary hospitals. Application. At present, some domestic grass-roots hospitals mostly use ordinary hernia plain film for laparoscopic hernia repair. Conventional ordinary hernia plain film for laparoscopic hernia repair requires multi-point anatomical positioning of the hernia mesh during laparoscopic operation. Adjust the position of the patch every time, the operation time is long, the operation is difficult, and the pain of the patient is increased.
