    摘要： A medical sealant applicator device for delivery of a multi-component sealant including a first body having a base, a first syringe plunger, a second syringe plunger, and a longitudinal channel, laterally interposed between the first syringe plunger and the second syringe plunger. Each of the first syringe plunger and the second syringe plunger is oriented to extend in a first direction from the base. The first syringe plunger has a first free end having a first proximal plunger piston. The second syringe plunger having a second free end having a second proximal plunger piston. A second body of the medical sealant application device has a first syringe chamber, a second syringe chamber, and a longitudinal fluid chamber laterally interposed between the first syringe chamber and the second syringe chamber. The longitudinal fluid chamber has a proximal end and a distal end.

    摘要： Powered drivers (10) for inserting an intraosseous device (160) into a bone and associated bone marrow are disclosed. Some of the powered drivers (10) may include a housing (12) having a distal end (14) and a proximal end (16); a motor (18) disposed in the housing (12); a driveshaft (34) extending outward from the distal end (14) of the housing in a direction away from the proximal end (16); a gearbox (32) coupled to the motor (18) and to the driveshaft (34) such that activation of the motor (18) causes the driveshaft (34) to rotate; and a power source (40) configured to power the motor (18). A guard member (50) may be pivotably connected to the housing (12) and movable between a protective position and a non-protective position. The guard member (50) may be configured to cover the intraosseous (10) needle assembly in the protective position and to expose the intraosseous (10) needle assembly in the non-protective position. A biasing member (70) may be configured to urge the guard member (50) toward the non-protective position.

    摘要： A surgical trocar includes a connection unit, which: connects a first trocar body and a second trocar body such that the second trocar body can vertically move relative to the first trocar body when a trocar unit is inserted into and drawn out of a trocar body unit having the first trocar body and the second trocar body, such that when an external force is not applied, a state of being unfolded in the radial direction of the first trocar body is maintained; and has an extension member extending in the longitudinal direction of the first trocar body when the trocar unit is inserted into the trocar body unit such that the second trocar body moves relative to the first trocar body.

    摘要： A precision depth guided instrument, such as a Jamshidi needle, is provided for use in various surgeries related to the vertebrae. The instrument includes an outer cannula, an inner cannula and a stylet. After the cortical bone of a vertebra is penetrated by the outer cannula of the instrument, the depth of penetration of the inner cannula is adjusted by rotation of the inner cannula. The inner cannula is then moved further into the vertebrae, and a stop mounted on the outer cannula controls the depth of penetration of the inner cannula. The correct depth of penetration is determined by radiography prior to the procedure.

    摘要： A disposable needle hair transplanter includes: a plunger structure having an outer barrel defining a passage, a plunger assembly having at least one push needle movable within the passage of the outer barrel, and a hair transplantation depth controller drivingly connected with the plunger assembly via a link; a needle having a needle seat connected with the outer barrel and at least one needle tube in which a hair follicle is loadable, the hair transplantation depth controller serving to restrict the depth by which the needle tube is thrust into the scalp; and a hair follicle depth controller having a cylindrical structure fitted around the needle seat and a shaft tube connected with the cylindrical structure and coaxially disposed around the needle tube. The hair transplantation depth controller is disposed around the shaft tube and movable along the shaft tube toward or away from the scalp.
