Embodiment 1

[0021] refer to Figure 1 to Figure 3 , this embodiment provides a bone marrow cement sleeve for chronic osteomyelitis surgery, including an outer cylinder 1 and an inner cylinder 2, both of which are made of bone cement added with antibiotics, and the outer cylinder 1 and the inner cylinder 2 are made of bone cement added with antibiotics. The deviation between the outer diameter of the inner cylinder 2 and the two cross-sectional diameters of the osteotomy end is less than 10 mm, and the outer diameter of the inner cylinder 2 is 0.1 mm smaller than the inner diameter of the outer cylinder 1, that is, slightly smaller than the inner diameter of the outer cylinder 1. One end of the inner cylinder 2 extends into the outer cylinder 1, and one end of the inner cylinder 2 is slidably disposed in the outer cylinder 1 along the length direction of the outer cylinder 1. Preferably, one end of the inner cylinder 2 is also provided with a piston 3, and one end of the inner cylinder 2 pa...

Embodiment 2

[0024] refer to figure 1 , Figure 4 with Figure 5 , this embodiment provides a bone marrow cement sleeve for chronic osteomyelitis surgery, including an outer cylinder 1, an inner cylinder 2 and a second inner cylinder 7, the outer cylinder 1, the inner cylinder 2 and the second inner cylinder 7 are all added Made of bone cement with antibiotics, the outer diameters of the outer cylinder 1, the inner cylinder 2 and the second inner cylinder 7 are less than 10 mm from the diameters of the two sections of the osteotomy end, and the outer diameter of the inner cylinder 2 is smaller than the inner diameter of the outer cylinder 1 0.1mm, that is, slightly smaller than the inner diameter of the outer cylinder 1, one end of the inner cylinder 2 extends into the outer cylinder 1, and one end of the inner cylinder 2 is slidably arranged in the outer cylinder 1 along the length direction of the outer cylinder 1, preferably, One end of the inner cylinder 2 is also provided with a pis...

Abstract

The invention discloses a bone marrow cement sleeve for a chronic osteomyelitis operation and a use method thereof. The bone marrow cement sleeve comprises an outer sleeve and an inner sleeve, whereinthe outer sleeve and the inner sleeve are both made of bone cement added with antibiotics, the outer diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve, one end of the inner sleeve extends into the outer sleeve, and one end of the inner sleeve is arranged in the outer sleeve in a sliding mode in the length direction of the outer sleeve. The problems that existingosteotomy and bone transport surgery treatment of osteomyelitis is low in efficiency, high in required operation frequency, inconvenient in operation are solved. The invention belongs to the field ofchronic osteomyelitis treatment.

Description

technical field [0001] The invention relates to a bone marrow cement sleeve used in chronic osteomyelitis operation and a using method thereof, belonging to the field of osteomyelitis treatment. Background technique [0002] At present, osteomyelitis is a relatively common orthopedic disease, which is mainly caused by infection. The onset of osteomyelitis can be devastating to the patient, and delays in treatment after the illness can lead to systemic symptoms and manifestations. Osteomyelitis is a curable chronic disease that often occurs in adults. After getting this disease, antibiotic treatment and surgical treatment should be actively taken. Effective treatment can reduce the mortality rate. [0003] Surgical treatment is the best treatment for osteomyelitis. Surgical treatment can completely cure this disease. At present, the commonly used surgical treatment method is to amputate the diseased bone and gradually complete the amputated part through bone transfer. Metho...
