A mounting tool for mounting a flexible ring-shaped part of an anastomotic device on a rigid part of an anastomotic device is provided. The tool comprises a receiving portion (104) in a distal end of the mounting tool for receiving the flexible part thereat and a handle portion (103) proximally of said receiving portion (104). Said receiving portion (104) comprises an tubular sheet element (101), and a tubular displacement element (201), arranged within the tubular sheet element (101) to be longitudinally displaceable in relation to the tubular sheet element (101), such that a shelf (401) is obtained circumferentially of the tubular displacement element (106) and distally of the tubular sheet element (101). The shelf (401) is configured to receive the flexible part. A mounting tool for receiving a flexible ring-shaped part of an anastomotic device on a rigid part of an anastomotic device is also provided. This tool comprises a longitudinal guiding element (801) for passing through a central passage or lumen in a mounting tool according to above, and a connection plate (802) arranged distally on the longitudinal guiding element (801). The connection plate (802) is configured to connect to a rigid part of an anastomotic device. A kit is also provided.本發明提供一種裝配工具,其係用於裝配一接合裝置之一彈性部件於一接合裝置之一堅硬部件上。該工具包含一接收部分(104)於該裝配工具之一遠側終端以供接收該彈性部件並包含一握持部分(103)位於前述接收部分(104)之近側。前述接收部分(104)包含一管狀薄板元件(101)以及一管狀移動元件(201),該管狀移動元件被配置於該管狀薄板元件(101)中而得以縱向地相對於該管狀薄板元件(101)移動,因而可於該管狀移動元件(201)之周圍以及該管狀薄板元件(101)之遠側構成一格層(401)。該格層(401)係用於接收該彈性部件。本發明亦提供一種裝配工具,其係用於在一接合裝置之一堅硬部件上接收一接合裝置之一彈性部件。此工具包含一縱向導引元件(801)以供通過前述之一裝配工具的一中央通道或空腔,且包括一連接板(802)配置於該縱向導引元件(801)之遠側。該連接板(802)係用於連接至一接合裝置的一堅硬部件。本發明亦提供一套件。100‧‧‧部件101‧‧‧管狀薄板元件103‧‧‧握持部分104‧‧‧接收部分105‧‧‧中央部分106‧‧‧彈簧
