A cell transfer apparatus transfers cells scattered in a first container to a second container. The cell transfer apparatus includes a head with a suction tip, a movement mechanism for the head, a camera that captures images of the first container, a cell recognition unit that performs position recognition of the cells based on the images, and a control unit that controls the head and the movement mechanism to perform a transfer operation of the cells based on a result of the position recognition. The control unit gradually suctions the set quantity of target cells that is set to two or more in advance into the suction tip from among the cells scattered in the first container, causes the head to move to the second container, and then discharges the set quantity of the target cells suctioned into the suction tip to the same location in the second container.

A suction catheter system is described with a suction nozzle that can extend from a guide catheter of the like. The suction nozzle can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. A suction lumen extends from the proximal end of the guide catheter through at least part of the guide catheter central lumen and through the suction tip. Desirable suction flow can be established using the guide lumen to facilitate the suction. Also, a delivery catheter is described with an elastic tip that can track closely over a guidewire. The elastic tip of the delivery catheter can be expanded to provide for the delivery of medical devices past the tip.

Disclosed are devices, systems and methods for a removeable and replaceable tip for a surgical (or dental) suction cannula which facilitates the safe and effective removal of blood and other bodily fluids from a body cavity while allowing manipulation and / or management of various tissues therein. These devices protect delicate anatomic structures from excessive negative pressure while allowing effective suctioning of fluid and debris from the operative field.

A suction member for a high-volume evacuator (HVE) suction tool used in dental procedures. The suction member has a connection portion at a proximal end, a tubular portion connected to the connection portion, and a suction tip connected to the tubular portion at a distal end. The suction tip includes outwardly flared lobes and open-ended peripheral vent openings alternating about its circumference. The distal ends of the lobes are generally aligned in an oblique distal tangent plane inclined relative to a longitudinal axis of the tubular portion. The vent openings are spaced closer together towards a front side of the suction member, and the lobes include a widest and most flared rear lobe that is useful for soft tissue retraction.

Disclosed are devices, systems and methods for reducing noise from surgical and dental suction tips, especially Frazier and Fukushima type cannulas, by altering the size, shape, and contour of control valves. More specifically, the disclosed devices modify sound generated by traditional suction tips and / or thumbhole controls of various suction cannulas, (also called control valves, control vents, grip plates, and / or suction interrupters) by decreasing the intensity of the sound output of the suction cannula's amplitude and changing the frequency to a less annoying pitch.

This invention relates to a suction head and a skin rejuvenation device equipped with the suction head, comprising: a head body having a negative pressure forming space open to a surface in contact with the skin; an air negative pressure tube component located within the head body, connecting the suction port of the negative pressure forming space to a vacuum device in the control body; and a cream movement guide component installed within the negative pressure forming space at the suction port, guiding therapeutic cream moving along the inner side of the negative pressure forming space toward the suction port to the lower side, thereby preventing it from flowing into the suction port. This prevents the therapeutic cream from being sucked into the airflow path by negative pressure during treatment, thus preventing accidents caused by airflow path blockage and ensuring operational stability. It also improves the durability of the vacuum device and saves the cost and time required for repairing airflow paths blocked by therapeutic cream.

An electro-surgical pencil comprising: a housing forming an axially extending main suction passage from a proximal opening to a distal opening; a tube forming an extension of the main suction passage from the proximal opening to a proximal extension opening, the tube being configured for telescoping movement through the proximal opening; an electrode for cutting and / or coagulating tissue, the electrode being attached to the tube and extending axially from the proximal extension opening; and a suction tip attached to the tube and forming a further extension of the suction passage. Since both the tube and the suction tip are movable relative to the housing, a short and a long configuration can be obtained while good smoke removal capabilities are maintained.

Various forms of anti-clog suction tips apparatus are disclosed. An exemplary anti-clog suction tip apparatus includes a suction tip assembly having a suction tip with a suction opening at a first end thereof for removing debris through suction, a hose attachment portion for attaching the suction tip assembly to a suction source, and an ejection wire channel. The apparatus further includes an ejection wire assembly having an ejection wire extending within the channel and an ejection button integral with or connected to the ejection wire. Applying a force to the ejection button advances the ejection wire through the channel such that an end portion of the ejection wire enters the suction tip and dislodges debris clogging the suction tip. The ejection wire may include an enlarged end portion such as, for example a ball tip. One or more of the components of the apparatus may be single-use and disposable.

A root canal irrigation assembly, comprising a vacuum device, a suction element having an elongate suction tip, and a sonic device having a sonic handpiece for introducing sonic vibrations into the suction element and thus causing the suction tip to vibrate, wherein the rear end of the suction element is connected to the vacuum device such that an irrigation fluid containing tissue residues and / or bacteria can be suctioned out of a root canal. The suction element comprises an internal vibrator which is held in the suction tip and projects out of the front end thereof, wherein the suction tip and the internal vibrator are interconnected at their rear ends, wherein the suction tip is resiliently formed and dimensioned such that, when the suction tip is introduced into a root canal, the suction tip sealingly closes the root canal in the region of the root canal wall.

The present invention provides a suction device that facilitates the replacement of driver bits, and a power tool equipped with such a suction device. [Solution] The suction device 10 comprises a suction device body 20 attached to the tool body 14 so as to cover the bit fixing sleeve 18 of the power tool 12, a suction tip member 22 detachably attached to the suction device body 20, and a sleeve operating member 64 extending from the internal space 28 of the suction device body 20 through an operating opening to the outside of the suction device body 20. The sleeve operating member 64 is positioned to be operable in the front-rear direction along the rotation axis R. By operating the sleeve operating member 64 from the outside of the suction device body 20, the bit fixing sleeve 18 can be displaced from a fixed position that fixes the driver bit B to a release position in which the driver bit B can be removed.

The utility model discloses a disposable adjustable aspirator head which comprises an aspirator head body connected with an aspiration pipeline. The aspirator head body comprises a hollow pipeline body, a foam head arranged at the top end of the pipeline body, and an adjusting assembly arranged on the pipeline body close to one side of the aspiration pipeline; a bearing piece is arranged on the inner side of the end, close to the foam head, of the pipeline body, and the foam head is embedded in the bearing piece. According to the disposable adjustable aspirator head, due to the fact that the aspirator head body connected to an existing conventional aspiration pipeline is arranged, an aspirator can be prevented from being blocked, the adjustable aspirator head can be adjusted according to requirements in an operation, and convenience is provided for clinical surgical operations.
