Surgical drawing hook

Abstract

The invention discloses a surgical drawing hook. The surgical drawing hook comprises a drawing hook (1), a drawing hook connection rod (2) and a hollow cylinder (3), wherein the drawing hook (1) is connected with the drawing hook connection rod (2) through a rubber band (4); scale marks (7) used for marking stress size of the drawing hook are arranged on the drawing hook connection rod (2) along the axis of the drawing hook connection rod (2); a circumferential groove is formed in the end close to one side of the drawing hook connection rod (2) of the drawing hook (1); a through hole matched with the groove is formed in the bottom surface of the cylinder (3); a through hole with the size matched with the size of the drawing hook connection rod (2) is formed in the top surface of the cylinder (3); the through hole in the bottom surface of the cylinder (3) is clamped in the groove; the through hole in the top surface of the cylinder (3) is sleeved on the drawing hook connection rod (2); a handle (6) is arranged at the tail of the drawing hook connection rod (2). The surgical drawing hook is capable of accurately displaying the stress size of the drawing hook so as to avoid the occurrence of situations such as tissue avascular necrosis caused by excessive force of the surgical drawing hook and the like.

Description

technical field [0001] The invention relates to a surgical retractor, in particular to a surgical retractor capable of precisely controlling strength. Background technique [0002] At present, when the hospital performs body surface surgery on a patient, it is necessary to cut the patient's skin and muscles, and then use a surgical retractor to pull the surgical wound to fully expose the field of view suitable for surgery; however, the existing surgical retractor is not accurate. It can clearly show the force of the retractor, which will lead to ischemia and necrosis of muscle tissue due to the excessive force of the surgical retractor, which will increase the incidence of postoperative complications. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a surgical retractor, which can accurately display the force of the retractor, so as to avoid tissue ischemia and necrosis caused by excessive force of the surgical re...
