  • Publication number: 20230330304
    Abstract: To provide a method for suppressing the entry of scar tissue in the treatment of a tendon or ligament, promoting healing by intratendinous cells, and efficiently restoring the original function of the tendon. A gel material including a polymer gel for suppressing expression of type III collagen in the treatment of an injured or ruptured tendon or ligament, in which the polymer gel is a hydrogel having a three-dimensional network structure formed by crosslinking of hydrophilic polymers, and has a polymer content of from 1 to 5% by weight and an elastic modulus of from 100 to 10000 Pa.

  • Publication number: 20230293778
    Abstract: An object of the present invention is to provide a novel use in which a polymer gel material having a µm-scale porous structure can be suitably used. A gel material for regenerative medicine comprising a polymer gel in which hydrophilic polymer units are crosslinked with each other, wherein the polymer gel contains water as a solvent and has a three-dimensional network structure having two regions: a first region in which the polymer units are densely present and a second region in which the polymer units are sparsely present, and a mesh size composed of the first region is the range of 1 to 500 µm.

  • Publication number: 20230218797
    Abstract: An object of the present invention is to provide a hemostatic method, a vascular occlusion method, a tissue covering method, and a body fluid coagulation method that are safe and efficient using a polymer material that is a non-biologically derived synthetic product. A solution (pre-gel solution) is prepared that contains, under a specific concentration condition, a hydrophilic polymer capable of forming a hydrogel by intermolecular crosslinking and has a specific pH condition and specific ionic strength, and the solution is gelled in situ in an environment, such as a bleeding site or the interior of a blood vessel, where blood is present.

  • Publication number: 20230022586
    Abstract: A grasping device of the embodiment includes claw holding parts, a cam, pins, a motor, and a rail holding part. The claw holding parts are supported by rails in a slidable manner. The cam includes grooves or curved holes having a spiral shape provided around the rotation center and a hole provided at the rotation center. The pins each have one end engaged with the claw holding parts side and the other end engaged with the grooves or the curved holes of the cam. The motor includes a shaft to be fixed to the hole of the cam. The rail holding part is configured to hold the rails and engage a positioning jig with an end portion of the shaft at the side fixed to the cam and including a hole part with an inner peripheral surface where the outer peripheral surface of the jig is contactable.

  • Patent number: 6474227
    Abstract: With a method of controlling synchronous drive of a plurality of pressing machines, each of the pressing machines has a motor, a drive shaft to which a torque of a flywheel driven by the motor is transmitted through a clutch and a slide driven by the drive shaft so that a rotational position of the drive shaft of each of the pressing machines is synchronous each other. The method has a step of detecting actual velocity information of the motor and a step of detecting actual rotational-position information of the drive shaft. The detected actual rotational-position information is compared with the reference rotational-position information from a reference rotational position information generating section. Based on the result of the comparison, the reference velocity information from a reference velocity information generating section is compensated into characteristic reference velocity information of each of the pressing machines.
