A retractor-camera kit for minimally invasive surgery is provided. The kit includes a retractor comprising at least a top blade and a first side blade connected to one another through a hinge, a handle connected to the retractor, and a camera connected to the retractor via a designated holder to provide visualization of a surgical site while avoiding the need for an additional incision for passing an imaging unit therethrough.

The present application realizes easier and less invasive sputum suction. A suction object guiding device (100) guides a suction object from a side of an upper respiratory tract of a living body, and has a suction object discharge port (101) capable of discharging the suction object, a patient side connection interface (103) capable of being connected to a patient side, an inhalation interface (104) capable of being connected to an inhalation device, and a switching valve that switches a connection source of the patient side connection interface to either one of the suction object discharge port and the inhalation interface. The suction object guiding device (100) further has a housing (102) having the suction object discharge port (101), the patient side connection interface (103), and the inhalation interface (104), and the switching valve is configured to be provided in the housing in a slidable manner and capable of switching the connection source of the patient side connection interface to either one of the suction object discharge port and the inhalation interface.

The present invention provides a less invasive balloon catheter having a smaller outer diameter of a portion having a plurality of balloons arranged in a contracted state. A balloon catheter (1) has a group (11) of balloons including a plurality of balloons (10) arranged in parallel with each other in a circumferential direction z. When the group (11) of balloons are in a contracted state, each balloon (10) has a first fold part (21) and a second fold part (22), which are two fold parts (20) in the circumferential direction z, and a non-fold part (30), which is a part other than the fold parts (20), the first fold part (21) being positioned at an end of each balloon (10) on one side in the circumferential direction z, and the second fold part (22) being positioned at an end of each balloon (10) on the other side in the circumferential direction z.

The purpose of the present invention is to provide a tracker device which is less invasive to a patient, is excellent in safety, can be firmly fixed to the pelvis of the patient, can be easily removed after surgery, and is less invasive to the skin and bone after removal. This tracker device constitutes a navigation system used when performing orthopedic surgery, and comprises: a tracker unit (110) having optical markers (111)-(114); and a fixing member (120) for fixing the tracker unit (110) to the pelvis of a patient. The fixing member (120) comprises a spiral coil having a pointed end (121).

This invention relates to the field of injection device technology, and provides an injection device including a syringe and a launcher. The launcher has a launch tube into which the syringe is inserted and a drive assembly that drives the needle of the syringe to exit the launch tube. A handle is mounted on the launch tube, and a trigger assembly for limiting or releasing the syringe is mounted on the handle. This injection device uses a launcher to launch the syringe, which, in conjunction with the drive assembly, moves the syringe. During high-speed movement, the syringe can puncture the target site. Compared to traditional surgery, this method is more convenient for drug administration and less invasive. Compared to traditional neuroprotective treatments, it shortens the treatment time. Furthermore, the launcher has a simple structure, is easy to implement, and is inexpensive, saving patients significant treatment costs.

A medical material makes it possible to perform less invasive treatment of atrial septal defect and is unlikely to cause problems in the late post-treatment period. A medical material includes a substantially middle portion and two tubular portions (first tubular portion, second tubular portion) having a mesh structure formed of a bioabsorbable linear material and includes a proximal connecting part connected to a first end and a distal connecting part connected to a second end and threaded to a delivery cable. The proximal connecting part and the distal connecting part are configured to reversibly or irreversibly achieve a locked state and an unlocked state, the locked state being a state in which the proximal connecting part and the distal connecting part remain united, the unlocked state being a state in which the proximal connecting part and the distal connecting part do not remain united. When the distal connecting part is inserted into the proximal connecting part, the engaging portion of the distal connecting part engages with the engaged portion of the proximal connecting part to cause the medical material to transition from the unlocked state to the locked state.

The disclosed total blood volume determination systems and methods provide for a faster, simpler, more practical, less invasive, and more flexibly deployable device for blood volume measurement. These systems and methods are based on measuring, in a patient's bloodstream, the resonance of an agent injected into the circulating blood that allows for assessment of the agent's concentration and determination of the total blood volume. The agent may take a variety of forms, including an agent that is detectable via a non-invasive technique such as ultrasound. The agent may be measured over time and fitting the measurement data to provide an accurate determination of total blood volume.

Disclosed herein is an alternative method and device to traditional alveolar distraction osteogenesis, which typically necessitates bone destruction. This method employs a titanium rod with a screw head design connected to two peripheral protrusions. The lower protrusion anchors the device to the jawbone, while the upper protrusion supports a porous titanium plate beneath the periosteal tissue. By gradually rotating the screw head, the distance between the protrusions increases, promoting controlled, tension-free bone growth without necessitating bone destruction. This approach is advantageous where traditional methods are not feasible, such as bones affected by congenital defects, severe atrophy, or near-exposed nerve canals. The porous titanium plate acts as a scaffold, preventing periosteal tissue collapse and maintaining space for bone regeneration, while preserving the integrity of the periosteum. This innovation offers a more effective and less invasive solution for complex alveolar bone deficiencies.

The present disclosure provides various surgical instruments and delivery systems to properly implant spinous stabilization devices, such as for example, interspinous, interlaminar stabilization devices, in a less invasive manner than what is currently performed. The delivery system may be a tubular delivery system through which instruments and devices can pass. Methods for using these surgical instruments and delivery systems are also provided.
