Description

Technical Field

[0002] With the continuous development and update of orthopedic instruments, the use of minimally invasive technologies such as closed reduction of fractures, minimally invasive internal fixation technology, arthroscopic technology, etc. to treat orthopedic diseases has become more and more popular among patients and medical staff. Artificial total hip replacement is a prosthesis similar to human bone joints made of metal materials with good biocompatibility and mechanical properties. The joint prosthesis is implanted into the joint damaged by disease or injury by surgical methods. Its purpose is to eliminate pain and restore the joint's activity and original function.

[0003] After the operation, the patient needs to lie still and recuperate until the artificial total hip joint fits the human body perfectly before some restorative training can be carried out. During the lying still process, a triangular pillow is generally placed between the base of the patient's legs, and the patient is asked to clamp it by himself to fix the patient's lower limbs and avoid hip dislocation, which affects the effect of the operation and even causes the failure of the operation. For example, CN205322661U discloses a triangular pillow for hip replacement fixation. The triangular pillow is an isosceles triangle, and a fixing device is respectively arranged on the two waists of the triangular pillow. When the fixed triangular pillow is used for a long time, the inner side of the patient's legs is tightly attached to the two sides of the triangular pillow, and long-term use is easy to cause eczema and other problems due to airtightness and humidity at the contact position.
