A shaft and a handheld surgical device have an optimized shape for accommodating an instrument. This is achieved in that a peripheral border of a distal opening of a shaft for a handheld surgical device has a thickening facing outward at least in sections. Cut injuries can be avoided by this thickening due to the rounded borders of the distal opening.

The present disclosure relates to catheters, and more particularly, to urinary catheters that can be used with an endoscope as well as a catheter system comprising a catheter and an endoscope, wherein the endoscope is disposed in the lumen of the catheter. In one instance, a catheter system includes an endoscope and a catheter. The endoscope has an insertion tube sized and shaped to be inserted into a body lumen of a patient. The catheter includes an elongate body having an axis and proximal and distal end portions space apart from one another along the axis. The elongate body is sized and shaped to be received in the body lumen. The elongate body defines a lumen extending between the proximal and distal end portions. The lumen is sized and shaped to receive the insertion tube of the endoscope.

The present disclosure relates generally to bicycles. In particular, the present disclosure provides systems and devices for converting a standard bicycle into a cargo bicycle using various detachable components. The ability to convert a standard bicycle into a cargo bicycle and back again confers many advantages, including eliminating the need for a separate bicycle for transporting cargo and encouraging the use of bicycles as a mode of transportation.

A multi-functional endosurgical device (1) comprises a tube (3), an end effector (21), and a device operating part (4). The tube (3) several lengthwise extending channels (9) for supplying a liquid and suction to the end effector (21) and to apply current to perform diathermy. A slide rail assembly (5) comprises at a main slide guide body (46) that accommodates an end effector slider (47) and a junction slider (48). The end effector slider (47) slides in the guideway (54) and is connected to the effector sleeve (17) through one of the lengthwise extending channels to operate said effector sleeve (17) in relation to the end effector. The junction slider (48) also slides in the guideway (54) downstream the end effector slider (47). The junction slider (48) is connected to the tube (3) to arrange at least a first lengthwise extending channel (9), a second lengthwise extending channel (10) and a third lengthwise extending channel (15) of the tube (3) in communication with the end effector (21).

Method and system for treating a patient using an inflatable device. A removal device may be used to remove the inflatable device from the body. The removal device can have at least one manually-actuatable member and at least two opposing jaws at a distal end. At least one of the at least two jaws can be movable by actuation of the at least one manually-actuatable member. At least one of the at least two jaws can have a puncturing member.

A ureteroscope system including a handpiece, a catheter, and a cable. The handpiece has a catheter end, a control end opposite to the catheter end, a working channel port positioned proximate to the catheter end and distal to the control end, and a cable port positioned proximate to the catheter end and distal to the control end. The catheter extends from the catheter end of the handpiece, and includes a working channel in fluid communication with the working channel port, a distal end, and an image sensor positioned at the distal end of the catheter. The cable is connected to the handpiece at the cable port and configured to provide power to the image sensor and communicate with one or more electronic devices.
