A hydraulic stabilizer system for a portable medical imaging system. The system includes at least two hydraulic cylinders each having a shaft extending through a first wall of the respective cylinder, wherein each shaft is moveable relative to the respective cylinder. First and second ends of each shaft include a spring support element and a foot for contacting associated uneven floor portions. A retraction spring is located between the spring support element and an inner surface of the first wall of each cylinder. The system also includes a hydraulic circuit for supplying hydraulic fluid to the cylinders, wherein the cylinders are in fluid communication with each other. Hydraulic fluid is pumped into the cylinders to cause downward movement of the shafts until the feet contact the associated uneven floor portions such that the pressure exerted by the feet against the associated uneven floor portions is equalized.

A knob locking assembly for a laparoscopic medical device is provided. The knob locking assembly includes a lock configured to engage the knob locking assembly with a drive tube housing of the laparoscopic medical device in extended and retracted positions where the knob locking assembly rotates but does not translate with respect to the drive tube housing when engaged. The knob locking assembly also has a biasing member that provides a biasing force for biasing the lock in each of the extended and retracted positions to lock out longitudinal translation of the rotatable drive assembly when the knob locking assembly is engaged with the drive tube. In addition, the knob locking assembly includes an actuator to counter the biasing force for disengaging the lock to permit longitudinal translation of the rotatable drive assembly via the knob locking assembly when disengaged.

A medical device for performing a hysterectomy is provided. The medical device has a tissue incision assembly that includes a first cup nested within a second cup. The tissue incision assembly also includes a spacer assembly between the first cup and the second cup in order to maintain a spacing between the first and second cups. The tissue incision assembly also has a cutting implement that has a portion extending between, and movable with respect to, the first and second cups. The cutting implement can provide a circular cut guided via the spacing between the first and second cups.

A colpotomy device for performing a hysterectomy is provided. The device includes a flexible drive tube having a proximal end and a distal end and bendable therebetween. The device also has a rotatable cutting implement at the distal end of the flexible drive tube at a specified offset from a bendable longitudinal axis of the flexible drive tube. Furthermore, the device includes couplings located within the flexible drive tube and rotatable about the bendable longitudinal axis of the flexible drive tube. The couplings can be in a series that includes inter-coupling joints and transmits a rotational force between the proximal and distal ends of the flexible drive tube through a variable angle between the couplings. The variable angle can correspond to bending of the drive tube in order to drive rotation of the cutting implement at the specified offset about the axis of the flexible drive tube.

A colpotomy device having a tissue treatment assembly for performing a hysterectomy is provided. The tissue treatment assembly comprises an elongated body defining a longitudinal axis and an end effector coupled to a distal portion of the elongated body. The end effector can be offset from and rotatable about the longitudinal axis. The tissue treatment assembly also has an axial first electrical contact coupled to the end effector, where the axial first electrical contact is affixed to and rotatable with the end effector. Moreover, the tissue treatment assembly includes a circumferential second electrical contact that can be arranged to contact the axial first electrical contact throughout a rotation of the end effector about the longitudinal axis.

An electrogustometer comprises an interface (4) capable of receiving a stimulation instruction, and a current generator (8) arranged to produce a stimulation current. The interface (4) is arranged to obtain a digital command from the stimulation instruction, and the electrogustometer further comprises a digital-to-analogue converter (6) suitable for converting the digital command into a DC voltage, the different digital commands inducing discrete respective voltage values. The current generator (8) is arranged to convert the DC voltage into a stimulation current with a strength of between 0 and 250 A, depending on the discrete voltage value, and varies by fixed steps of between 0.05 A and 1 A.

A method for early identification of the presence of coronary heart disease or an arrhythmia in a patient being examined, including the steps of: (i) non-invasive recording of EKG signals at the patient's heart when resting, (ii) filter processing of the recorded EKG signals, (iii) transferring the filtered EKG signals into orthogonalised measurement variables on the basis of vectorcardiography, and (iv) entering the orthogonalised and, in the case of incorrectly applied electrodes, corrected measurement variables into a system based on artificial intelligence in which known findings data from comparative patients are stored and, by comparing these entered orthogonalised measurement variables with the findings data of the comparative patients within the Al system, a diagnosis is obtained for the patient being examined.

An intelligent defecation device for living creature includes a device body, a supporting portion, an image module, and a first analysis module. The supporting portion is formed within the inner side of the device body for accommodating a moisture absorption member so as to allow the living creature to leave over its excrement therein. The image module is also arranged at the device body for dynamically capturing the images of the excrement in the supporting portion and outputting the image. The first analysis module is arranged in the device body and connected with the image module to analyze and calculate the defecation mode with the image based on preset or accumulated data, so as to generate a signal when an abnormal defecation mode is diagnosed.

A method for performing a full-field stimulus threshold (FST) test on a test subject, the method comprising: delivering at least one visual stimulus to at least one eye of the test subject, wherein the least one visual stimulus comprises a flash of light having an intensity and a duration, wherein the intensity of the flash of light is adjusted over the duration of the flash of light; obtaining at least one response from the test subject, wherein the at least one response corresponds to whether the test subject perceived the at least one visual stimulus; and determining the lowest intensity of light that the test subject is able to perceive based on the at least one response from the test subject.

A trumpet expandable vertebral device, includes: a center shaft including a cylinder body and an expanding ring connected to each other, wherein the cylinder body has a far end which has an outer thread; and an expandable portion including an end collar, a connection part and plural expandable plates, wherein the expandable portion is located outside and surrounds the center shaft, and the connection part connects the end collar with the plurality of expandable plates; wherein when the expanding ring moves toward the end collar, the trumpet expandable plates are expanded.
