The ultrasound probe includes: a piezoelectric element; and a housing to which the piezoelectric element is mounted. An end of the housing is connected to the supporting, and the housing is provided with an ultrasound passing hole which is disposed outside the supporting rod. The sealing cover has an ultrasound passing window which is formed at a position corresponding to the ultrasound passing hole.

A portable depilation instrument includes a shell, and a depilation mechanism and a heat dissipation mechanism inside the shell. The shell is provided with at least two outlets and one inlet, the shell introduces an external cooling medium from the inlet, the heat dissipation mechanism includes a heat conductive component, the depilation mechanism includes a refrigeration element and an emitter, the heat conductive component isolates the refrigeration element from the emitter in two mutually sealed channels, namely, a first channel and a second channel, the first channel and the second channel are respectively in communication with two outlets, and one of the outlets allows the first channel or the second channel to pass through inside of the entire shell from one end to the other end. Due to complete isolation and a push force, air can be discharged only from a respective corresponding outlet after a heat exchange.

The present invention relates to an ablation assembly (100) to treat target regions of a tissue (41) in organs (44) comprising: an ablation catheter (1) comprising an elongate shaft (13) having a longitudinal main direction (X-X), said elongate shaft (13) comprising at least a shaft distal portion (17), said shaft distal portion (17) comprising a shaft distal portion distal end (19);
said ablation catheter (1) comprising an inner lumen (118) arranged within the elongate shaft (13);
said ablation catheter (1) comprising a shaft ablation assembly (20) fixedly disposed at said shaft distal portion (17), the shaft ablation assembly (20) being configured to deliver both thermal energy for ablating said tissue (41) and non-thermal energy for treating said tissue (41); at least a shape setting mandrel (26) disposed within the ablation catheter (1), the shape setting mandrel (26) being insertable within the inner lumen (118) and removable from the inner lumen (118),
wherein the shape setting mandrel (26) is free to move in respect of the inner lumen (118) avoiding any constraint with said shaft distal portion (17) during the shape setting mandrel insertion,
wherein the shape setting mandrel (26) comprises at least a pre-shaped configuration and the shape setting mandrel (26) is reversibly deformable between at least a straight loaded configuration and said pre-shaped configuration,
wherein, when the shape setting mandrel (26) is fully inserted in the shaft distal portion (17), the shape setting mandrel (26) is configured to shape set said shaft distal portion (17) with said pre-shaped configuration.

A device is described for treating a nasal airway by modifying a property of a nasal tissue of or near a nasal valve of the airway, without using a surgical incision or an implant, to decrease airflow resistance or perceived airflow resistance in the nasal airway. Various embodiments include an elongate shaft, a bipolar radiofrequency delivery member extending from one end of the shaft, and a handle attached to the elongate shaft at an opposite end from the radiofrequency delivery member. The radiofrequency delivery member is sized to be inserted into a nose and configured to at least temporarily deform the nasal tissue and deliver radiofrequency energy. The radiofrequency delivery member includes two rows of protruding electrodes disposed on a tissue contact surface, and the device is configured to deliver radiofrequency energy from one row of electrodes to the other row of electrodes.

A surgical instrument includes a movable handle movable relative a housing to manipulate an end effector assembly, and a latch assembly. The latch assembly includes a latch arm including a latch post, and a latch track defining an entry path, a latching path, a saddle, an un-latching path, and a return path. The latch post moves through the entry path, the latching path, and into the saddle upon movement of the movable handle from an un-actuated position to an over-actuated position and back to an actuated position to lock the movable handle. The latch post moves from the saddle through the un-latching path and the return path upon movement of the movable handle from actuated position to the over-actuated position and back to the un-actuated position. The return path includes a ramped surface configured to inhibit reverse travel of the latch post into the return path.

A surgical instrument includes a housing and a trigger assembly. The trigger assembly includes a trigger including a drive portion and a manipulation portion, a rocker, a linkage, and a slider. The trigger is pivotably coupled to the housing such that the drive and manipulation portions are moved in different directions in response to actuation of the trigger. The drive portion of the trigger is pivotably coupled to the rocker. The linkage is pivotably coupled to the rocker and the housing at opposing end portions thereof. The slider is pivotably coupled to the rocker and operably coupled to the deployable component. Actuation of the manipulation portion of the trigger moves the drive portion of the trigger distally to thereby urge the rocker distally, pivot the linkage about the second end portion thereof, and slide the slider distally to deploy the deployable component distally.

Methods and surgical tools for treating back pain use a spinal facet debridement tool with cautery and denuding action and minimally invasive protocol that can denude and cauterize soft tissue associated with a synovial capsule of the spinal facet joint.
