244 results about "Hematoma" patented technology

A hematoma (US spelling) or haematoma (UK spelling) is a localized bleeding outside of blood vessels, due to either disease or trauma including injury or surgery and may involve blood continuing to seep from broken capillaries. A hematoma is benign and is initially in liquid form spread among the tissues including in sacs between tissues where it may coagulate and solidify before blood is reabsorbed into blood vessels. An ecchymosis is a hematoma of the skin larger than 10mm.

Circumferential medical closure device and method

A flexible medical closure screen device for a separation of first and second tissue portions is provided, which includes a mesh screen comprising tubular vertical risers, vertical strands with barbed filaments, and horizontal spacers connecting the risers and strands in a grid-like configuration. An optional perimeter member partly surrounds the screen and can comprise a perimeter tube fluidically coupled with the vertical risers to form a tubing assembly. Various input / output devices can optionally be connected to the perimeter tube ends for irrigating and / or draining the separation according to methodologies of the present invention. Separation closure, irrigation and drainage methodologies are disclosed utilizing various combinations of closure screens, tubing, sutures, fluid transfer elements and gradient force sources. The use of mechanical forces associated with barbed strands for repositionably securing separated tissues together is disclosed. The use of same for eliminating or reducing the formation of subcutaneous voids or pockets, which can potentially form hematoma and seroma effects, is also disclosed. Alternative embodiments of the invention have circumferential configurations for approximating and closing separated tissue portions such as tendons, nerves and blood vessels. Tissue closure methods include the steps of circumferentially applying a screen to separated tissue portions and penetrating the tissue portions with prongs.

Intracranial hemorrhage early-stage hematoma minimally invasive elimination system

InactiveCN102973305AReduced entry caliberEasy accessSurgeryINTRACRANIAL EPIDURAL HEMORRHAGEMechanical crushing
The invention discloses an intracranial hemorrhage early-stage hematoma minimally invasive elimination system, comprising a puncture catheter system and a hematoma ultrasonic crushing mechanism, wherein the puncture catheter system comprises a puncture catheter body and a puncture needle core which is movably sleeved inside the puncture catheter body; an internal diameter of the puncture catheter body is 4-5 mm; a suction branch pipe is arranged at the position of the puncture catheter body, which is close to the tail end of the puncture catheter body; a sealing cover is mounted on the pipe opening of the suction branch pipe; the front end of the puncture needle core is bullet-shaped, and extends out the front end of the catheter body; the hematoma ultrasonic crushing mechanism comprises an ultrasonic crushing vibrator and an ultrasonic vibration rod connected with the ultrasonic crushing vibrator; the ultrasonic vibration rod is more than the puncture catheter body in length; and a thread is arranged at the front part of the ultrasonic vibration rod. The intracranial hemorrhage early-stage hematoma minimally invasive elimination system provided by the invention is simple in structure; and the puncture catheter body can conveniently puncture a catheter into a cranium, and is difficult to block. Compared with the conventional puncture catheter, the intracranial hemorrhage early-stage hematoma minimally invasive elimination system can more easily and naturally lead hematoma, so that the damage and the haemorrhage on brain tissues by the conventional mechanical crushing can be avoided.

Acupuncture method and device combining ultrasonic vibration with traditional acupuncture

ActiveCN109363929AAddress or avoid ultrasound doseFix or avoid frequencyAcupunctureDevices using mechanical vibrationsVibration amplitudeAcupuncture treatment
The invention discloses an acupuncture method and device combining ultrasonic vibration with traditional acupuncture, and relates to the technical field of ultrasonic treatment. The method comprises the steps that ultrasonic waves excited by a frequency conversion ultrasonic wave function generator are transmitted to an acupuncture needle, the syringe needle of the acupuncture needle generates longitudinal vibration or torsional vibration or bending vibration or longitudinal and torsional compounding vibration under the effect of ultrasonic waves, and by controlling the ultrasonic modal, the ultrasonic dosage, the ultrasonic frequency, the ultrasonic intensity, ultrasonic waveforms, acting time and the like, acupuncture points are stimulated to generate a certain physiological reaction toachieve the treatment effect. The device comprises the frequency conversion ultrasonic wave function generator, a time delay, a piezoelectric transducer, an amplitude transformer and the acupuncture needle; according to the method and device, no large-amplitude motion needs to be performed by means of the acupuncture needle, only micro-meter-scale vibration amplitude is generated under ultrasonicvibration, the problems of fainting during acupuncture treatment, needle sticking in acupuncture, needle bending, needle breaking, hematoma and the like during traditional needle manipulation are reduced, the problem that the effect of an existing ultrasonic acupuncture simulation method is not obvious is solved, and the good practical value is achieved.

Hemorrhoids treatment apparatus and operating method thereof

The invention relates to a hemorrhoids treatment apparatus and an operating method of the hemorrhoids treatment apparatus. The hemorrhoids treatment apparatus comprises a permanent magnet or an electromagnet, a motor for driving the permanent magnet or the electromagnet to rotate, and a sleeve sleeving the permanent magnet or the electromagnet. In use of the hemorrhoids treatment apparatus, the sleeve is sleeved by a sanitary sleeve, hemorrhoids-treating ointment is applied to the sanitary sleeve, then the sleeve is inserted into the anus, the motor is started for driving the permanent magnet or the electromagnet to rotate, and then the rotation magnet-therapy treatment is carried out on the hemorrhoids. The rotation magnet therapy has the efficacies that an alternating magnetic field output from the sleeve enables the human body cells to generate induction, so that the cell membrane potential is changed, then the membrane depolarization effect is generated, thus the permeability of tissue cells is enhanced, consequently, the cell arrangement is in order, and finally, the effective absorption of the local inflamed tissue for hematomas and edema exudation is facilitated. The four different physical therapy methods including rotation magnet-therapy treatment, hot compress treatment, vibratory massage treatment and 650NM laser treatment are adopted, and ani sphincter administration is also matched for carrying out comprehensive treatment on the internal and external hemorrhoids inflammation.
