Methods and devices are disclosed for puncturing tissue, comprising an assembly for puncturing a target tissue. The puncture device of the assembly has a distal tip configured to puncture the target tissue and at least one proximal marker, formed on the proximal portion of the puncture device. The supporting member of the assembly includes a proximal end, a distal end, and a lumen for receiving the puncture device. The puncture device is configured to enable advancement and withdrawal of the supporting member overtop of the puncture device. Alignment of the proximal end of the supporting member and the at least one proximal marker of the puncture device occurs when the distal tip of the puncture device protrudes from the distal end of the supporting member.

A surgical apparatus includes a housing, a test port retainer, a pressure test chamber, and an image capture assembly. The housing includes a pressure test port. The test port retainer includes a test port retainer housing, a probe seal, and a liquid exclusion barrier. In one aspect, the test port retainer also includes a hydrophobic membrane mounted within the test port retainer housing. The pressure test chamber includes a manifold and a central tube. The first end of the central tube is affixed to the image capture assembly to form a pressure seal, and the second end of the central tube is coupled to the test port retainer so that the pressure test port communicates with the interior volume of the central tube through the test port retainer.

The present invention relates generally to a system and method for measuring the structural characteristics of an object. The object is subjected to an energy application processes and provides an objective, quantitative measurement of structural characteristics of an object. The system may include a device, for example, a percussion instrument, capable of being reproducibly placed against the object undergoing such measurement for reproducible positioning. The system does not include an external on/off switch or any remote on/off switching mechanism. The system also includes a disposable feature or assembly for minimizing cross-contamination between tests. The structural characteristics as defined herein may include vibration damping capacities, acoustic damping capacities, structural integrity or structural stability.

A surgical device and method for performing a controlled resection of the neck of a femur during a hip replacement procedure. The surgical device includes a body portion. The body portion has a mounting portion. The mounting portion is mountable on a femoral head of the femur to position the body portion with respect to a center of the femoral head. The body portion also has an opening for mounting the body portion on an intramedullary pin located in an intramedullary canal of the femur. The surgical device also includes a resection guide. The resection guide is adjustably locatable at a plurality of positions on the body portion for positioning a resection plane indicator of the resection guide with respect to the neck of the femur according to a measured radius/diameter of the femoral head.

An input control device is disclosed. The input control device can be configured to operate in different modes depending on proximity data provided by a proximity detection system. The input control device can include a feedback generator configured to generate feedback in response to the input control device switching between operational modes, the proximity data provided by the proximity detection system, and/or other conditions of the surgical procedure, robotic surgical tool, surgical site, and/or patient. The input control device can include a variable resistance assembly for resisting input control motions applied to an actuator thereof. Additionally or alternatively, the input control device can include an end effector actuator assembly for repositioning the end effector actuator based on feedback from a paired robotic surgical tool.

Surgical systems are provided. In one exemplary embodiment, a surgical system includes a first scope device having a first portion within an extraluminal space and a second portion positioned within an intraluminal space. The first scope device transmits image data of a first scene. A second scope device is disposed within the extraluminal space and transmits image data of a second scene. The first portion of the first instrument is present within the field of view of the second scope device to track the first scope device relative to the second scope device. A controller receives the transmitted image data of the first and second scenes, to determine a relative distance from the first scope device to the second scope device within the extraluminal space, and to provide a merged image. At least one of the first and second scope device in the merged image is a representative depiction thereof.

An apparatus includes a handle assembly, a shaft assembly, an end effector, and an auto-tensioning feature. The handle assembly includes a body and a plunger. The shaft assembly includes an external sheath that is fixed to the handle body and an interior shaft that is coupled to the plunger. The interior shaft is slidable relative to the external sheath. The end effector is configured to encompass a bodily lumen and includes a flexible member extending distally from the interior shaft. A first coupling element is fixed to the distal tip of the flexible member. A second coupling element is fixed to the external sheath. The first and second coupling elements are magnetically attracted to each other and are biased toward each other such that the flexible member defines an adjustable loop. The auto-tensioning feature is configured to bias the plunger portion proximally relative to the handle body.

The present invention is a method for controlling a Davinci surgical device. Firstly, controlling an operation part of a remote operation device to enter the inner of a body for executing a surgical operation. Then, an image capturing unit captures a plurality of corresponding surgical images to a control device, and the control device obtains a first torque component, a second torque component and an element action of the remote surgical device according to the surgical images to operate an output strength of the remote surgical device for further generating corresponding strength feedback by the output strength. Thus, the user can get the control status of the remote surgical device to prevent accidental iatrogenic injury from over-force and to proceed with the operation with improved accuracy.

A control method, a control system, an electronic device and a readable storage medium for a capsule endoscope are disclosed. The method comprises: obtaining the initial distance H between the capsule endoscope and an external magnetic field generating device based on magnetic field information when the capsule endoscope is positioned in the vertical direction of the magnetic field generating device in an initial state; presetting a target area according to the force balance of the in vivo capsule endoscope, and adjusting the distance between a second permanent magnet and the capsule endoscope to locate the capsule endoscope in the target area; monitoring the acceleration of the capsule endoscope, and determining the vertical component of acceleration of the capsule endoscope; and adjusting the current of the electromagnetic induction coil according to the vertical component of the acceleration to finely adjust the force balance of the capsule endoscope in the target area.

A system to measure and display the orientation of a handheld instrument is disclosed.
