Endoscopic device

Abstract

The present application provides an endoscopic device having at least one shaft, which has at least one portion deflectable in at least one plane, and having at least one deflection mechanism, which is configured to deflect the deflectable portion of the shaft and includes, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member, and includes at least one flexurally slack control train, which is configured to adjust a deflection of the deflectable portion. At least the second connection member includes at least one connection member main body, which includes a passageway for guiding the control train, and at least one radial opening which is connected to the passageway and via which the control train is insertable into the passageway.

We claim: 
     
         1 . An endoscopic device having at least one shaft, which has at least one portion deflectable in at least one plane, and having at least one deflection mechanism, which is configured to deflect the deflectable portion of the shaft and comprises, arranged in series, at least one first connection member and at least one second connection member interacting for a deflection with the first connection member, and comprises at least one flexurally slack control train, which is configured to adjust a deflection of the deflectable portion, wherein at least the second connection member comprises at least one connection member main body, which comprises a passageway for guiding the control train, and at least one radial opening which is connected to the passageway and via which the control train is insertable into the passageway. 
     
     
         2 . The endoscopic device as claimed in  claim 1 , wherein the connection member main body has an at least partially radially extending connection recess, which connects the passageway and the radial opening to each other. 
     
     
         3 . The endoscopic device as claimed in  claim 2 , wherein the connection recess describes a curved path. 
     
     
         4 . The endoscopic device as claimed in  claim 1 , wherein the second connection member comprises at least one closure body, by means of which, at least in an inserted state of the control train, the radial opening is closable. 
     
     
         5 . The endoscopic device as claimed in  claim 4 , wherein the closure body is connectable to the connection member main body with force-fit and/or form-fit engagement. 
     
     
         6 . The endoscopic device as claimed in  claim 4 , wherein the closure body is designed as a clamping ring. 
     
     
         7 . The endoscopic device as claimed in  claim 1 , wherein the second connection member has at least one further connection member main body. 
     
     
         8 . The endoscopic device as claimed in  claim 7 , wherein the connection member main body and the further connection member main body are separated from each other in a position relative to each other in which a radial opening of the connection member main body and a radial opening of the further connection member main body are congruent with each other. 
     
     
         9 . The endoscopic device as claimed in  claim 7 , wherein the first connection member main body and the further connection member main body are connected in a further position relative to each other in which a passageway of the connection member main body and a passageway of the further connection member main body are congruent with each other. 
     
     
         10 . The endoscopic device as claimed in  claim 7 , wherein the connection member main body and the further connection member main body are connected to each other with force-fit and/or form-fit engagement. 
     
     
         11 . The endoscopic device as claimed in  claim 7 , wherein the control train, in a mounted state, keeps the connection members of the deflection mechanism pretensioned and in this way presses the connection member main body and the further connection member main body together. 
     
     
         12 . The endoscopic device as claimed in  claim 1  wherein the deflection mechanism comprises at least one further control train, and the second connection member has at least one further passageway, and also one further radial opening, in which the further control train is inserted. 
     
     
         13 . The endoscopic device as claimed in  claim 12 , wherein the further passageway and/or the further radial opening are arranged offset, in the circumferential direction of the connection member, relative to the passageway and/or to the radial opening. 
     
     
         14 . An endoscope and/or endoscopic instrument having at least one endoscopic device as claimed in  claim 1 . 
     
     
         15 . A surgical system having at least one endoscopic device as claimed in  claim 1  and having at least one surgical robot. 
     
     
         16 . A method for operating and/or producing an endoscopic device as claimed  claim 1 .
