Abstract

The invention relates to a pelvis tensioner. The pelvis tensioner structurally comprises a C-shaped connecting frame, two pelvis front positioning assemblies and two pelvis rear positioning assemblies; each pelvis front positioning assembly comprises a front fixing piece, a tensioning needle and a front connecting piece, wherein the front fixing piece is fixed at a pubic symphysis position, the tensioning needle is of a screw rod structure with a ball head at the bottom end, and the bottom end of the tensioning needle is connected with an upper spherical pair of the front fixing piece; each pelvis rear positioning assembly comprises a rear fixing piece, a positioning column and a rear connecting piece, wherein the rear fixing piece is fixed at the iliac crest position of the pelvis on thecorresponding side, the bottom end of the positioning column is fixedly connected with the top end of the rear fixing piece, and the front connecting piece and the rear connecting piece are both positioned at the corresponding positions of the C-shaped connecting frame. The pelvis tensioner has the advantages of simple structure, convenience in use, small operation wound surface and suitability for popularization and application.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a pelvic tensioner. Background technique [0002] The pelvis will expand due to fractures or pregnancy and childbirth. Especially when women give birth, the pelvis will be stretched and widened or the pubic bone will be separated. The pelvic cavity is full of important organs and important blood vessels and nerves that innervate the lower limbs. Not only will the pubic bone, Pain in the waist, crotch, and leg roots sometimes seriously affects normal activities and leads to disability of the patient. Therefore, it is usually necessary to correct and reset the damaged pelvis. [0003] The existing pelvic correction and reduction devices usually have complex structures, inconvenient operation, large wounds, and due to their large weight and volume, patients are usually unable to wear clothes and walk after application, which seriously affects the normal self-care ability...
