Patent number: 11166756Abstract: In order to deliver porous particulate material into a cavity via a thin tube without substantially crushing the porous particulate material, a two-step process and an apparatus for use therein are provided. The two-step process involves inserting a first rod into the thin tube to push the porous particulate material therein; removing the first rod from the tube; and (a) inserting a second rod into the thin tube, or (b) joining a second rod with the first rod, and inserting the joined first rod and second rod, to push the porous particulate material which remains in the thin tube. In (a), the first rod has a cross sectional area significantly smaller than that of the thin tube, and the second rod has a cross sectional area which is about equal to that of the thin tube. In (b), each of the first rod and the second rod has a cross sectional area about half of the thin tube.Type: GrantFiled: January 23, 2018Date of Patent: November 9, 2021Assignee: JOY MEDICAL DEVICES CORPORATIONInventors: Chien-Ping Ju, Jiin-Huey Chern Lin, Yen-Chun Chen, Bing-Chen Yang, Kuan-Ting Chen

Patent number: 10980620Abstract: A resin-retained denture bridge having an improved bonding between a false tooth or teeth of the bridge and a retainer wire of the bridge is provided in the present invention, wherein a coupling recess is formed on a lingual side of the false tooth and a protrusion or an omega-shaped bend is formed on the retainer wire. The protrusion or omega-shaped bend is received in the coupling recess of the false tooth after or prior to a resin being filled in the coupling recess, which is then cured to form a secure engagement, so that the false tooth is bonded to the retainer with the end portions of the retainer wire extending laterally from the false tooth.Type: GrantFiled: April 23, 2018Date of Patent: April 20, 2021Assignee: JOY MEDICAL DEVICES CORPORATIONInventors: Luh-Yuan Lin, Jiin-Huey Chern Lin, Chien-Ping Ju, Yen-Chun Chen

Patent number: 8480678Abstract: The present invention discloses a method of using beads to create a cavity in a bone, which includes introducing beads into a bone by applying a pressure on said beads, wherein the beads are metallic beads able to be attracted by a magnet; and withdrawing the beads from the bone by magnetic force. Preferably, a pocket is disposed in the bone prior to the introduction of beads, and the introduction and withdraw of the beads are carried out with respect to said pocket.Type: GrantFiled: September 8, 2008Date of Patent: July 9, 2013Assignee: Joy Medical Devices CorporationInventors: Jiin-Huey Chern Lin, Chien-Ping Ju, Pong-Jeu Lu

Patent number: 8409212Abstract: The present invention discloses a technique for forming a hardened orthopaedic paste in a bone cavity, which involves a forced-feeding balloon rupture mechanism. This mechanism includes continuously or intermittently injecting a liquid or gas into a perforated balloon containing a hardened orthopaedic paste therein in a bone cavity until the perforated balloon is dilated to exceed a critical size, and thus ruptures.Type: GrantFiled: June 21, 2011Date of Patent: April 2, 2013Assignee: Joy Medical Devices CorporationInventors: Pong-Jeu Lu, Jlin-Huey Chern Lin, Chien-Ping Ju
