Abstract
The utility model discloses a sleeve in a bone cement adding device used in orthopedic operations. The sleeve is cylindrical, and when a piston is pushed out, the inner wall of the sleeve is in tightfit with the piston, thus ensuring the sealing property and no leakage of the sleeve. Meanwhile the sleeve is simple to operate.
Description
Affiliated technical field
This utility model relates to the parts in a kind of medical apparatus and instruments, the sleeve pipe in particularly a kind of bone cement adding apparatus that is used for bone surgery.
Background technology
In prosthetic replacement's operation process, bone cement has been widely used in clinical at present, in operation process, is fastened on people's bone for making artificial prosthesis, promptly need use bone cement.The use of bone cement at first is that it is in harmonious proportion, and uses the bone cement adding apparatus that bone cement is imported in the bone cavity of corresponding site then.And the bone cement adding apparatus that uses at present all exists leakage to expect, sealing is poor, the problem of complicated operation, causes the waste of bone cement in the operation process and has prolonged operating time.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency of the prior art, and provide a kind of and have good sealing property, do not leak material, the sleeve pipe in simple to operate and the bone cement adding apparatus that security performance is high.
The technical solution of the utility model is: the sleeve pipe in a kind of bone cement adding apparatus, its special character are that sleeve pipe is a cylinder design.
The beneficial effects of the utility model are: improve sealing, do not leak material and simple to operate.
