Abstract
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).
Core Innovation
The invention is an endosurgical device having a tube with a proximal tube end and an opposite distal tube end, and at least one lengthwise extending channel extending there-between. The tube includes a first lengthwise extending channel for supplying a liquid to an end effector, a second lengthwise extending channel for removing matter from the end effector, and a third lengthwise extending channel for accommodating an electrical wire connected to the end effector to apply current to perform diathermy.
The device includes an effector sleeve surrounding the tube at least at the opposite distal tube end and enclosing at least the opposite distal tube end of the tube. The device operating part comprises a slide rail assembly with at least a main slide guide body that accommodates an end effector slider and a junction slider.
The main slide guide body has a guideway with a proximal guide end and an opposite distal guide end that receives the tube, and the end effector slider slides in the guideway at the opposite distal guide end. The end effector slider is connected to the effector sleeve to operate the effector sleeve in relation to the end effector, and the junction slider slides in the guideway between the proximal guide end and the end effector slider.
The junction slider is connected to the tube to arrange the first lengthwise extending channel, the second lengthwise extending channel, and the third lengthwise extending channel in communication with the end effector. This structure connects liquid supply, matter removal, and diathermy electrical wire routing to an end effector while using the slide rail assembly to provide relative movement that places the tube channels into communication with the end effector.
Claims Coverage
The partial content provides one independent claim. It includes five inventive features centered on a multi-channel tube, an effector sleeve, and a slide rail assembly with an end effector slider and a junction slider.
End effector and multi-channel tube for diathermy and matter removal
A tube with a first lengthwise extending channel for supplying a liquid to the end effector, a second lengthwise extending channel for removing matter from or at the end effector, and a third lengthwise extending channel for accommodating an electrical wire connected to the end effector to apply current to perform diathermy.
Effector sleeve surrounding the distal tube end
An effector sleeve surrounds the tube at least at the opposite distal tube end and encloses at least the opposite distal tube end of the tube.
Slide rail assembly with end effector slider and junction slider
The device operating part comprises a slide rail assembly having at least a main slide guide body that accommodates an end effector slider and a junction slider, with a guideway receiving the tube and enabling sliding of the end effector slider and the junction slider in relation to the tube.
End effector slider connected to effector sleeve
The end effector slider slides in the guideway at the opposite distal guide end and is connected to the effector sleeve to operate the effector sleeve in relation to the end effector.
Junction slider connected to the tube to arrange channel communication
The junction slider slides in the guideway between the proximal guide end and the end effector slider and is connected to the tube to arrange the first lengthwise extending channel, the second lengthwise extending channel, and the third lengthwise extending channel in communication with the end effector.
Across the independent claim, the inventive concept is the combination of a tube with liquid supply, matter removal, and diathermy electrical wire accommodation channels, with an effector sleeve and a slide rail assembly using an end effector slider and a junction slider to bring these channels into communication with the end effector.
