A surgical retractor is configured to provide surgical access in thoracic surgery, for example through an intercostal incision. The surgical retractor includes at least one inflated or inflatable member to cushion the ribs and surrounding tissue from injury or trauma. In one embodiment, the inflatable member is configured as an inflatable ring with a concave outer surface for engaging and spreading apart two adjacent ribs when the ring is inflated. In another embodiment, the inflatable ring can be combined with a substantially rigid inner ring for supporting and rigidifying the retractor. In yet another embodiment, a plurality of substantially rigid retractor blades is mounted on a spreading track or the like. One or more inflatable members or an inflatable ring are used to cushion the tissue from the rigid retractor blades.

The present invention provides a system and a method for distending a body tissue cavity of a subject by continuous flow irrigation by using a dynamic pump, such as a centrifugal pump, on the inflow side and a positive displacement pump, such as a peristaltic pump, on the outflow side, such that the amplitude of the pressure pulsations created by a the said outflow positive displacement pump inside the said tissue cavity is substantially dampened to almost negligible levels. The present invention also provides a method for accurately determining the rate of fluid loss, into the subject's body system, during any endoscopic procedure without utilizing any deficit weight or fluid volume calculation, the same being accomplished by using two fluid flow rate sensors. The present invention also provides a system of creating and maintaining any desired pressure in a body tissue cavity for any desired cavity outflow rate. The system and the methods of the present invention described above can be used in any endoscopic procedure requiring continuous flow irrigation few examples of such endoscopic procedures being hysteroscopic surgery, arthroscopic surgery, trans uretheral surgery, endoscopic surgery of the brain and endoscopic surgery of the spine.

The invention relates to a variable tension chest support for use by patients having undergone thoracic surgery. The chest support may be worn directly on the skin of a patient and comprises a band of stretchable material (1) and one or more grips (6) which are wholly or partially concealed within pockets (4) with which the patient may alter the tension of the chest encircling band. The device allows a patient to modify the level of tension applied to the chest, thus managing their recovery process, while providing a basic level of support at all times the support is in use.

The invention discloses a surgical rehabilitation nursing bed for thoracic surgery department. The nursing bed comprises a bed body, wherein a going-through groove is arranged in the middle of the interior of a fixed boss; one end of three groups of electric telescopic rods, which are distributed by equal spacing, is connected to one side of the interior of the going-through groove; protective plates are connected to the other ends of the electric telescopic rods; more than four groups of connecting bosses, which are distributed by equal spacing, are arranged at two sides of the bed body; sliding shafts are arranged between the connecting bosses; sliding plates, which are uniformly distributed by equal spacing, are arranged in the middles of sliding shafts; U-shaped supporting rods are arranged at the upper sides of the sliding plates; baffle cloth is arranged in the middles of the U-shaped supporting rods; the U-shaped supporting rods, which are driven along with the moving of the sliding plates, are moved along the axial lines of the sliding shafts, so that the baffle cloth is driven to cover the upper side of a patient without contact with the body of the patient; therefore, theproblem that incision pain due to compression can be caused easily when the body is covered by bedding or clothing can be solved; and via a wireless caller, the patient can be helped conveniently, and medical personnel can conduct treatment conveniently.

The invention belongs to the field of medical instruments, particularly relates to a thoracic surgery wound cleaning device and aims to solve the problem of inconvenience in cleaning due to the fact that cleaning is affected as tube heads of liquid outgoing tubes and liquid sucking tubes are prone to mutual interference when existing thoracic surgery wound cleaning devices are used for cleaning. The device comprises a box fixed on a supporting mechanism and a cleaning mechanism connected on the box, the inside of the box is divided into a cleaning liquid storage cavity, a sewage storage cavityand a mounting cavity, and a conveying pump and a backflow pump are fixedly mounted in the mounting cavity. By arranging a hard flushing pipe, a hard liquid absorbing pipe, a gear, a first rack, a second rack, a U-shaped holding rod, a controller, the conveying pump, the backflow pump and a forward-backward rotation motor, continuity of wound flushing and accumulated liquid sucking is high, timecan be saved, and efficiency can be improved.

A method for the early identification and prediction of an abrupt reduction in kidney function in a patient undergoing cardiothoracic (CT) surgery, including Cardio-Pulmonary Bypass (CPB), comprises contacting a urine sample from the patient with a capture molecule for a biomarker, especially πGST, specific for the distal region of the renal tubule and which biomarker is released from said region when there is damage to said region indicative and predictive of an abrupt reduction in kidney function, the biomarker being detectable as early as intraoperatively or in the recovery stage post CT surgery, for example prior to transfer of the patient to the Intensive Care Unit (ICU), allowing for immediate corrective medical intervention. The method can be used to detect Acute Kidney Injury (AKI) and a requirement for Renal Replacement Therapy (RRT) namely dialysis, earlier than two hours post CT surgery and as early as zero hours post or during CT surgery or CPB.

The invention discloses a terminal operating system for a robot and a vision navigation minimally invasive surgical robot. The terminal operating system for the robot comprises a substrate, wherein a locking device is arranged on the substrate and comprises a main locking frame and a side locking frame; and surgical puncture needles are arranged on the main locking frame and the side locking frame. The terminal operating system for the robot also comprises a calibration template, wherein black-and-white square texture is arranged on the calibration template and can be identified by a visual system of the robot; the calibration template is parallel to the upper surface of the substrate; and the calibration template and the substrate can be relatively rotated. The visual system of the vision navigation minimally invasive surgical robot identifies the position information of the calibration template, and the robot judges the position information of the surgical puncture needles according to the information. The terminal operating system for the robot has a simple structure, low cost and strong adaptability and universality, can be used for controlling and guiding scalpels of neurosurgery, osteological surgery, orthopedics and abdomen and chest surgery, and not only can be used for calibration of space positions but also can be used for position trailing of a terminal manipulator of the robot.
