Multifunctional abdomen retractor

Abstract

The invention relates to a multifunctional abdomen retractor which comprises a cross piece (1), a supporting rod (2), a rack type amplitude changing rod (3), a rocking bar (5) and a hook plate (6). The supporting rod (2) can be positioned in the cross piece (1) in a liftable manner through a stopper bolt; the rack type amplitude changing rod (3) is mounted on a universal base (12); and the hook plate (6) is hooked at the end part of the rack type amplitude changing rod (3). The multifunctional abdomen retractor is characterized in that a convex plate (13) is connected to the lower part of the universal base (12) and is pivotally mounted on a pin shaft (15) at the upper end of a connector (14); the lower end of the connector (14) is inserted and mounted in an inserting hole at the upper part of the supporting rod (2) and can be rotationally positioned in the inserting hole through an elastic bolt (4) and an annular groove (16) at the lower part of the connector (14); a supporting rod sleeve (7) is also mounted on the supporting rod (2) at the lower part of the connector (14); an L-shaped curved rod (8) is mounted on the supporting rod sleeve (7); a fastening device (9) is mounted on the curved rod (8); and a long handle hook plate (10) is tightly fixed in the fastening device (9). The invention has simple structure and large traction and can finish the traction of abdomens on any position, thereby obtaining ideal operation field.

Description

technical field [0001] The invention relates to a medical auxiliary device, especially an abdominal retractor used in abdominal surgery to pull apart the opened abdominal cavity so that the operation field can be fully exposed, specifically a multifunctional abdominal retractor device. Background technique [0002] At present, in liver transplantation, hepatic lobectomy, biliary tract surgery, total or proximal gastrectomy, splenectomy, and portal azygos segmental flow surgery, upper abdominal surgery with subcostal incision and abdominal straight or transverse abdominal incision are used. In incision surgery, in order to obtain an ideal surgical field, it is necessary to keep the opened abdomen in a good state of retraction. For this reason, various abdominal retractors have been invented to replace manual traction and relieve people from heavy physical labor. Liberated, obtained good use effect, the abdominal retractor that the patent No. 032779372 that has obtained autho...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that most of the existing abdominal retractors can only be applied to the upper abdomen, and to design a multi-functional abdomen that can be used for both the upper abdomen and the lower abdomen, has a large pulling force, and can adjust the angle arbitrarily retractor
