Femoral myelocavity file entryway protective sleeve provided with handheld device

Abstract

The invention provides a femoral myelocavity file entryway protective sleeve provided with a handheld device. The femoral myelocavity file entryway protective sleeve comprises a sleeve body, a pipe diameter regulating ring which is connected to one end of the sleeve body and the handheld device which is arranged between the sleeve body and the pipe diameter regulating ring, wherein the handheld device is capable of freely rotating between the sleeve body and the pipe diameter regulating ring; and scale marks are arranged on the outer wall of the sleeve body. According to an embodiment of the invention, the handheld device comprises a handheld handle and a connecting rod. According to another embodiment of the invention, the sleeve body is a hollow kaleidoscope-type adjustable sleeve; and the pipe diameter regulating ring is a rotary regulating device which is capable of regulating the inner diameter of the sleeve body by rotating. The protective sleeve disclosed by the invention is reasonable in design, simple in overall structure and convenient to hold in operations. Meanwhile, the pipe diameter of the sleeve can be regulated to adapt to myelocavity files which are different in model and diameter; therefore, the protective sleeve has good compatibility with operation tools from different manufacturers.

Description

technical field [0001] The invention relates to a medical device, more specifically, to a protective sleeve for the entrance channel of the femoral medullary cavity file which is convenient to hold during the operation. Background technique [0002] Artificial hip replacement has a long history. The world's first total hip replacement was performed by Dr Phillip Wiles in 1938. In the 1960s, Sir John Charnley, with his outstanding contributions, made artificial hip surgery one of the more successful surgical treatments in medicine. [0003] At present, hip replacement surgery is widely carried out all over the world. Hundreds of thousands of people in the United States receive this surgery every year. According to domestic data in 2014, the number of artificial knee and hip replacements has exceeded 400,000 per year. The implantation of the femoral prosthesis is an important step in this operation, and most of the prostheses today require the use of distal medullary canal ra...

Problems solved by technology

Once the skin is damaged, it may be combined with poor healing and increase the risk of infection. If the hip abductor muscles are damaged, it will directly affect the postoperative gait and function of the patient, and seriously affect the curative effect of the operation.

[0004] In the prior art, alternatives such as syringe sleeves are also used for protection, but using the syringe sleeve as the entry sleeve of the file is very inconvenient, especially it is not conducive to holding during the operation, and because the syringe sleeve is Round shape, which is not conducive to adjusting the angle and orientation of the sleeve during the operation

[0005] On the other hand, due to the increasing type and diameter of intramedullary cavity files, it is necessary to replace the sleeve and other substitutes, and even the size of the sleeve and other substitutes is difficult to match, which increases the difficulty of the operation
