Methods and systems identify defects in a medical device and tailor a protocol, namely, further recommended action, for the device based on a combination of the nature of the defects and procedural data including patient data and/or medical instrument record data. Computer-implemented instructions are used to determine the presence and nature of the defects. Artificial intelligence and/or algorithms may be used to implement the computer-implemented instructions, and process image data from a digital camera system. Upon identification of a defect present, the detection system may notify users of the presence of the defect, as well as provide further recommended action to be taken regarding the medical device, reducing potential instrument failure, patient injury or death. The methods and systems may be integrated into existing disinfection and sterilization systems and techniques currently used in medical facilities, such as hospitals and surgery centers.

The present invention discloses an auxiliary visible light rod for multisource end-expiratory CO.sub.2 monitoring. The auxiliary visible light rod comprises a handle, a pump body, a medicine compartment, a rod body and a bracket. The handle is separately connected with the medicine compartment, the pump body and the rod body, and one end of the rod body is connected with a rod head. A lamp and an atomizing head are arranged in the rod head. A circuit tube is connected with the external wall of the rod body, one end of the circuit tube is connected with a display screen, and the other end of the circuit tube is connected with a camera in the rod head. The bracket sleeves the rod body and is fixed to the outer side of an oral cavity or a chin of a patient, and thus the stability of the rod body is improved.

A manometry system includes a manometric catheter configured to sense pressure within a gastrointestinal tract, a computer in communication with the catheter, and a display. The manometric system may further include at least one of a remote controller configured to couple to the catheter, a strap configured to secure the catheter to a patient's head, or an RFID scanner configured to sense a location of one or more RFID tags attached to or embedded in the catheter.

Biopsy caps and seals, and methods for making and using the same may be provided in conjunction with an endoscope assembly. A seal may include a main body including a circumferential outer wall surrounding a central lumen. The seal may include at least one support wall extending radially from the outer wall towards a center of the lumen, and at least one helical flap extending from the support wall helically downward along an inner surface of the outer wall, where the at least one helical flap defines an opening at the center of the lumen. The seal may alternatively include a plurality of projections extending radially inward from the outer wall towards a center of the lumen, where the plurality of projections are arranged in a series of circumferentially and angularly offset layers.

Some implementations of the disclosure relate to an adapter, comprising: a channel running through the length of the adapter from a first opening to a second opening of the adapter, wherein a shaft of an endoscope is configured to be threaded through the channel; a first coupler configured to removably secure the adapter to a second coupler of the endoscope, the first coupler comprising the second opening; and a rigid attachment segment comprising a surface configured to removably couple the adapter to an instrument or second adapter. The surface of the rigid attachment segment may include multiple grooves and sections alternating along the longitudinal length of the rigid attachment segment, each section protruding relative to the grooves and comprising a recessed indentation or protrusion; and the multiple sections and grooves configured such that the instrument or second adapter can be coupled to the adapter in multiple lengthwise positions.

A speculum includes a handle; a lower leaf extending forward and distally from the handle; at least one upper leaf supported on the handle; a lever pivotally coupled to the handle; and a pin extending from the lever and slidably coupled to the at least one upper leaf. Movement of the lever relative to the handle causes the lever to slide the pin and pivotally move the at least one upper leaf relative to the lower leaf from a collapsed position to an open position.

Some implementations of the disclosure relate to an endoscope, comprising: a shaft comprising: a distal end; and a proximal end comprising a rigid attachment segment configured to be removably coupled to an adapter or instrument, a surface of the rigid attachment segment comprising: a groove and a section adjacent the groove, the section protruding relative to the groove and comprising a recessed indentation or protrusion; and a housing coupled to the shaft. The surface of the rigid attachment segment may include multiple grooves and multiple sections alternating along the longitudinal length of the rigid attachment segment; each of the sections protrudes relative to the grooves and comprises a recessed indentation or protrusion; and the multiple sections and the multiple grooves are configured such that the instrument or the adapter can be coupled to the endoscope in a plurality of lengthwise positions.

A laparoscopic imaging apparatus has a shaft having a proximal end opposite a distal end, wherein the proximal end is configured for attachment to an actuator, wherein a longitudinal axis extends through the shaft, between the proximal and distal ends, wherein the distal end is configured for insertion into patient anatomy and for attachment of one or more laparoscopic tools, wherein at least a first laparoscopic tool at the distal end pivots on a first gimbal apparatus that is actuable, from the actuator at the proximal end of the shaft, to rotate the at least the first laparoscopic tool about the longitudinal axis of the shaft and, further, to rotate the at least the first laparoscopic tool about at least a second axis, orthogonal to the longitudinal axis.

Various systems and methods may guide, support, and/or house instruments. One exemplary system includes a guide tube having a manipulation section and mated with rails carrying instrument control members. Moving the rails with respect to the guide tube, or another point of reference, can control movement of the manipulation section.

A system comprises a medical instrument, including a sensing tool, and a processing unit configured to apply a segmentation function using a first seed to a three-dimensional image of a patient anatomy to create a model; receive position data from the instrument while navigating the patient anatomy; register a position of the instrument with the model; receive data related to the patient anatomy from the sensing tool; and update the model in response to detecting a difference between the model and the patient anatomy. Updating the model includes reapplying the segmentation function using a second seed corresponding to a passageway of the patient anatomy that is not present within the model. Detecting the difference between the model and the patient anatomy includes analyzing temporal information obtained from shape data generated by the sensing tool while the instrument traverses portions of the patient anatomy not represented by the model.
