Problems solved by technology

[0018] Considering the rapid increase in viscosity of conventional fluid cements with the passage of time, it is necessary for the surgeon using a syringe to be able to estimate the viscosity state of the fluid cement efficiently, easily and with sufficient precision, however this is not possible with known devices Make it happen

Embodiment Construction

[0029] With particular reference to these figures, a device for filling a bone cavity, particularly an acetabular cavity, with fluid cement is generally indicated by the reference numeral 1 .

[0030] The device 1 comprises a delivery channel 2 for a fluid cement F, for example a bone cement of the acrylic resin type, which may be a radiopaque substance or other similar substance.

[0031] The transfer channel 2 is substantially rectilinear in shape and has a first opening 3 formed at one end of the channel, and a second opening 4 formed at the opposite end.

[0032] The first opening 3 can be coupled with a dosing device for dispensing the fluid cement F, for example a syringe S ultimately fitted to a gun P of known type.

[0033] In detail, a connecting device 5 for connecting with a syringe S is provided at one end of the delivery channel 2 where the first opening 3 is formed.

[0034] This connection means consists of a cylindrical fitting coaxial to the delivery channel ...

Abstract

A device (1) for filling a bone cavity, especially an acetabular cavity, with a fluid cement, comprising a delivery channel (2) for delivering the fluid cement (F), the delivery channel (2) having a first opening ( 3) and a second opening (4), the first opening is coupled with a feeding device for dispensing fluid cement, the fluid cement flows out through the second opening, the transfer channel is connected with the filling of the bone cavity The fluid filling element (6) is connected. The filling element has a useful feeding surface larger than the conveying channel and comprises a generally plate-shaped body, the main opposite surface of which defines a first side (7) connected to the conveying channel and for filling Inject the second side (8) of fluid cement. Additionally, the second side has a fluid cement receiving edge positionable in abutting contact with the edge of the bone cavity and includes peripheral folds of the plate-like body extending from the body itself in a generally crosswise fashion. side.

Description

technical field [0001] The present invention relates to a device for filling a bone cavity, especially an acetabular cavity, with a fluid cement. Background technique [0002] As a matter of common knowledge, arthroplasty, in which a prosthetic device is implanted into a bone or joint in the body, typically requires a certain amount of cement (acrylic or similar) to hold the prosthesis permanently in place. [0003] In many different kinds of implant procedures, bone cement is injected through a syringe that may be mounted on a dosing gun containing the fluid cement and has a needle, rigid cannula, or the like, ready for use. [0004] After the free end of the cannula is inserted into the cavity to be filled, the fluid cement is injected directly into place via a syringe. [0005] Although this is a particularly practical and effective means of filling cavities in the femur, humerus, vertebrae, etc., it has been found that this device is not suitable if bone cement needs to...
