Remote bone cement filling device

Abstract

The invention relates to a remote bone cement filling device which comprises a casing pipe, an outer pipe and a threaded outer pipe. The front end of the outer pipe is connected with an inlet formed in the back end of the casing pipe, and the back end of the outer pipe is connected with the front end of the threaded outer pipe; a movable plug is arranged in the casing pipe, a spring pipe is arranged in the outer pipe, and a push rod is arranged in the threaded outer pipe, wherein the push rod penetrates through the back end wall of the threaded outer pipe to form sliding fit with the back end wall of the threaded outer pipe, or the push rod penetrates through the back end wall of the threaded outer pipe to form spiral fit with the back end wall of the threaded outer pipe; the front end and the outer end of the spring pipe are connected with the plug and the push rod respectively. Accordingly, remote operation is achieved, wherein the length of the outer pipe is larger, therefore, a doctor can operate the device at a distance, and the X-ray radiation time is shortened; the fast and slow pushing functions are achieved, wherein the two different functions of the product are achieved through different operation methods, therefore, the selectivity is high, and convenience and reliability are achieved.

Description

technical field [0001] The invention relates to a remote bone cement filling device. Background technique [0002] Bone cement, also known as bone cement, is used as a filling material for bone defects. The current common clinical uses include: treating pathological vertebral body fractures as a filling material in percutaneous vertebroplasty and percutaneous kyphoplasty; Application of bone cement for support and stabilization in joint replacement or revision joint replacement surgery; treatment of vertebral compression fractures caused by osteoporosis. [0003] The structure of the previous bone cement filling device is relatively simple, including a sleeve and a push rod. The push rod is set in the sleeve, and the bone cement in the sleeve is pushed out by the movement of the push rod. The defects of the previous bone cement filling device mainly include: [0004] 1. The length of the traditional bone cement filling device is short, and the doctor can only operate it at ...
