摘要:
An endoscope (1) having a handle with a handle housing (2) and an insertion tube (3) extending from said handle (2) and terminating in a tip part (4) at the distal end of the endoscope (1). A working channel and having a distal end and a proximal end extends within the insertion tube (3). The endoscope further comprises motion transfer means (53, 54) extending within said working channel and adapted to operate a tool (55) at the exit port of the tip part (4) in response to the activation of an operating member (22). The working channel comprises a generally tubular working channel wall. The distal working channel end comprises an exit port at the tip part (4) at the distal end of the endoscope (1). The proximal working channel end comprises an end sealing means accommodated within the handle housing (2). An entry port is provided between the distal working channel end and the proximal working channel end.
摘要:
A teleoperational assembly is disclosed which includes an operator control system and a plurality of manipulators configured to control the movement of medical instruments in a surgical environment. The manipulators are teleoperationally controlled by the operator control system. The system further includes a processing unit configured to display an image of a field of view of the surgical environment, determine association information about the manipulators and the operator control system, and display badges near the medical instruments in the image of the field of view of the surgical environment. The badges display the association information for the medical instrument they appear associated with.
摘要:
A surgical device for grasping both tissue and a suture during arthroscopic surgery. The surgical device includes jaws having retrograde teeth preventing tissue from slipping out of the jaws. When closed, the distal end of the jaws form a suture passage allowing a suture to slide therethrough so that its ends can be retrieved through a cannula and a knot can be tied in the suture.
摘要:
A minimally invasive surgical system (100) includes a surgical instrument (12) having an elongate body portion (20) and an oversleeve (14), through which the elongate body portion of the surgical instrument is extendable. A valve assembly (30) is associated with one of the oversleeve or the surgical instrument. Mating structure (22, 24) is associated with two or more of the oversleeve, the surgical instrument and the valve assembly, the mating structure is operable to limit or prevent relative movement between the oversleeve and the surgical instrument.
摘要:
Grasper comprising at least two movable parts, wherein each of the movable parts is mounted on a support and the supports of the two movable parts share a common base or base structure, and wherein a relative position of the movable parts with respect to each other is variable by changing the relative position of the supports with respect to each other, wherein the supports of the movable parts comprise flexural members.
摘要:
Mechanical end effector (1) comprising at least two movable parts (4, 5), wherein each of the movable parts (4 resp. 5) is mounted on at least two supports (6, 6' resp. 7, 7'), wherein a relative position of the movable parts (4, 5) with respect to each other is variable by changing the relative position of the supports (6, 6'; 7, 7') with respect to each other, and wherein the supports (6, 6'; 7, 7') of the movable parts (4, 5) comprise bendable members, wherein the bendable members are equipped with mechanical properties that arrange for flexing of the bendable members when a force applied by the supports (6, 6'; 7, 7') of the movable parts (4, 5) exceeds a predefined value and the bendable members are embodied as cooperating bands (10, 11; 12, 13) to arrange that flexing of the cooperating bands (10, 11; 12, 13) provides a visual feedback to a user.
摘要:
A system for performing single port laparoscopic procedures includes a deployment frame and a plurality of tools. The tools are pivotally mounted on the frame and have end effectors which are translatably and rotatably disposed in the tool. A handle at the proximal end of the tool controls an end effector at the distal end of the tool. Movement of the tools relative to the frame is constrained so that they remain in a fixed geometric relationship which prevents the tools from interfering with each other during laparoscopic procedures.
