The present disclosure provides an endoscopic surgery apparatus that includes an insertion tube having a passage formed inside, and that is to be inserted into a patient's urethra; a laser part that is installed such that it can reciprocate in the passage, and that separates a prostate adenoma from a patient's prostatic capsular surface; a hemostasis part that is installed such that it is spaced apart from the laser part and can reciprocate in the passage, and stops bleeding of a bleeding blood vessel of the patient's prostatic capsular surface; a camera part that is located in the passage and that photographs inside of the patient's prostate; and a transfer part that selectively transfers the laser part and the hemostasis part.

The present invention provides a protective sheath, a hysteroscope equipped therewith, and a nephroscope equipped with the same, used to prevent contaminants from contaminating electrical connecting lines connected to the endoscope. The protective sheath includes an inner sheath (1) and an outer sheath (2), which are sleeved together, the outer sheath (2) has a cylindrical structure, the inner sheath (1) includes a straight cylindrical portion and a bell mouth portion, the bell mouth portion is located on an insertion end side of the inner sheath (1), a side wall of the bell mouth portion is provided with a plurality of grooves extending from the bell mouth portion to the straight cylindrical portion, and a plurality of elastic sheets (12) are formed at the insertion end of the inner sheath (1); a connecting portion cooperating with a self-locking quick connector (7) is formed on the inner wall of each elastic sheet (12); and a hollow cavity is disposed between the inner sheath (1) and the outer sheath (2), and a compressed waterproof jacket (3) is disposed in the hollow cavity, one end of the waterproof jacket (3) is fixedly sheathed on the inner sheath (1), and the other end of the waterproof jacket (3) can be pulled through a non-insertion end of the protective sheath. The protective sheath is lightweight, compact, and easy to operate. The protective sheath effectively protects the electrical connecting lines from being contaminated during use, thereby preventing short circuit, contamination and other situations, furthermore, the protective sheath is low in production cost and can be used as a disposable medical device.

Systems and methods for processing electronic images from a medical device comprise receiving an image frame from the medical device, and determining a first color channel and a second color channel in the image frame. A location of an electromagnetic beam halo may be identified by comparing the first color channel and second color channel. Edges of an electromagnetic beam may be determined based on the electromagnetic beam halo, and size metrics of the electromagnetic beam may be determined based on the edges of the electromagnetic beam. A visual indicator on the image frame may be displayed based on the size metrics of the electromagnetic beam.

A sheath assembly for use with an endoscope and an endoscope that includes the sheath assembly. The sheath assembly can include an elongate tubular sheath configured to thread onto a shaft of the endoscope. The sheath can include a pliable segment at a distal end of the sheath, and a tensile filament extends along a circumference of the pliable segment. The tensile filament can form a cinching loop at a distal end of the pliable segment. The sheath can be displaceable along the endoscope between a retracted position and an extended position. The pliable segment can extend distally beyond a distal end of the endoscope to form a chamber, and proximal displacement of the tensile filament tightens the cinching loop to convert the chamber from an open configuration to a closed configuration.

A basket apparatus is described that assists in removing objects from within a patient. The apparatus includes a number of pull wires, each pull wire physically coupled to a different capstan that individually actuates one of the pull wires. The apparatus also includes an outer support shaft itself including a number of channels through which the pull wires traverse. The portions of the pull wires extending out of the outer support shaft form a basket of adjustable size, shape, and position. The pull wires are attached together at a tip located at a distal end of the basket apparatus. By controlling the actuation of the various pull wires, the basket's shape, position size can be manipulated to reposition the basket around an object located within a patient, independent of or in conjunction with motion of the remainder of the apparatus or an associated endoscope.

Virtual reality (VR) surgical systems with haptic feedback are described herein that can be used to simulate several instruments and surgeries. The instruments can include a tool assembly; first and second brackets each having first shafts that are rotatably coupled at first and second end regions of the tool assembly and second shafts that are rotatably coupled to first and second robotic arms; a surgical tool assembly coupled to an end portion of the tool assembly and having an elongated member that extends within the tool assembly; an elongated member position sensor assembly configured to provide position information of a position of the elongated member to a computing unit; and an elongated member force feedback assembly housed within the cavity and coupled to the elongated member. The elongated member force feedback assembly is configured to provide haptic feedback to the user of the instrument.

A medical instrument drive assembly includes a base portion, a first set of one or more drive outputs, a platform secured to the base portion, and a latching mechanism. The first set of one or more drive outputs are coupled to and/or extending from the base portion and are configured to drive a first medical instrument. The platform is secured to the base portion and movable between an elevated configuration and a depressed configuration. The platform is biased in the elevated configuration. The latching mechanism is configured to cause the platform to be held in the depressed configuration.
