US 4232670 AAbstract
1. A tube-type supply container for viscous media, in particular bone cement, that is adapted to be inserted in an appliance provided with a manually actuable push rod, said supply container comprising:a cylindrical tube, both ends of said tube being open, one of said ends having first thread means adjacent thereto; injection pipe means including a relatively elongated pipe portion of relatively small diameter and a conically flared portion, said pipe portion being formed of a shearable, elastic material, said conically flared portion having second thread means by which the conically flared portion can be connected to one of the ends of said cylindrical tube by coaction with said first thread means; a plug-like piston that is sealingly displaceable within said cylindrical tube and adapted to be actuated by said push rod; and a funnel member having a cylindrical portion adapted to be slid on the outer side of either end of said cylindrical tube and having an abutment in its interior cooperating with either end face of said cylindrical tube. 2. A tube-type supply container set forth in claim 1, wherein said conically flared portion includes a tube-like extension adapted to be introduced into said elastic pipe portion and secured by a clamp.
A syringe is already known by which a pipe-like tube filled with a viscous medium is insertable in a channel formed support bar (DE-GM No. 7,607,385). In the manipulation of the syringe, a pusher rod is longitudinally displaceably supported in the thrust of a plunger in the tube. The known apparatus has the advantage of bringing measured quantities of sterilized materials in a simple manner within a short period of time to the desired location. Its use is of particularly great advantage in orthopedic surgery for the injection of bone cement in the treatment of bone fractures and/or the insertion of endoprotheses.
The invention proceeds from the recognition that the pipe-like tube open at both ends can be used at the same time as the mixing vessel. For this purpose the plunger is initially inserted in an assigned end of the tube and left in the initial position. Thereafter, the bone cement powder is introduced and the fluid component added. After the stirring of the mixture the injection pipe is then fastened on the tube and the assembled arrangement inserted in the syringe, as is known, for example from DE-GM No. 7,607,385. The mixing of the bone cement components in a separate vessel is avoided.
The supply container shown in FIG. 1 is formed of four assembleable parts, namely a two-part injection pipe 10, a cylindrical tube 20, a plunger 30, and a funnel 40. The tube 20 is proportionately thin walled cylinder with a continuous inner bore, so that it is open at both ends. On the forward end a rapid locking thread 21 is formed on the outside.
For functional efficiency, the injection pipe 10 is formed out of two parts, namely a proportionately long pipe section 11 with a proportionately small inner diameter, formed out of a quantity produced tubing which is cut to the desired length. Its fastening is shown in detail in FIG. 3. On the rear end the injection pipe 10 is connected with a conical section 12, which overlaps the outside of tube 20 with a cylindrical section 13 the outside of tube 20. An inner quick locking thread 14 of the conical section 12 coacts with thread 21 of the tube 20. On the inside of the cylindrical section 13 a shoulder 15 is formed against which the edge surface of tube 20 lies, whereby the inner diameter of the cylindrical section 13 is the same as that of tube 20, so that an even transition is established between the conical section 12 and tube 20. A boss 16 sits on the narrow portion of the conical section 12 over which the tubing 11 is drawn (FIG. 3).
The plunger 30 includes a cylindrical ring, which on the forward end is sealed through a massive disc 32. On the inside of the ring 31 are arranged perpendicularly crossing webs 32 and 33 connected with the disc formed part 32. From the crossing point of the webs 32, 33 extends rearwardly a peg 34 which coacts with a not shown pusher rod of the syringe.
The plunger ring 31 includes, as is apparent from FIG. 2, a section 35 the outer side of which is smoothly cylindrically formed. It extends approximately two-thirds of the length of the plunger. Thereafter are rearwardly attached three ring formed circular ribs 36, which are sawtoothed formed in cross-section such that the forward surfaces 37 join the longitudinal axis of plunger 30 at a smaller angle than the rear surfaces 38. The outside the ribs 36 form a smooth ring-formed section 39 which runs parallel and coaxial to the cylindrical section 35. The outer diameter of the cylindrical section 35 corresponds to the inner diameter of tube 20. The outer diameter of ribs 36 is somewhat greater than the inner diameter of the tube so that the ribs 36, with the insertion of the plunger 30, are elastically deformed rearwardly and radially inward.
The funnel 40 has a cylindrical part 41, the inner diameter of which corresponds approximately to the outer diamter of tube 20. A conical part 42 is joined to cylindrical part 42. In the transition between the cylindrical part 41 and the conical part 42 a ring-like band 43 formed, which functions as a boss when the funnel 40 is pushed over one of the two ends of tube 20. When the funnel is pushed over the forward end, it serves as a filling funnel. When it is pushed on the rear end, it serves as a stand and simultaneously prevents the pusher 30 from falling downwardly out of the tube.
The parts 10, 20, 30 and 40 can be manufactured out of a suitable plastic material. They are, before the use, preferably individually placed in a sterilized packing. The injection pipe 11 has a proportionately long length, for example up to 36 cm. Its material is so selected that a shortening with a scapel or sharp knife is possible for each desired length. In this way can also long shaft prostheses be provided.
