The invention provides an electric intracavity cutting anastomat which comprises an anastomat body 1 and at least two cutting assemblies 2 which are connected with the anastomat body 1 in a switchable mode, namely, the anastomat body 1 can be matched with the at least two cutting assemblies 2, and different cutting assemblies 2 have different cutting strokes, so that when different cutting strokes are needed according to types and parts of cut tissues, the cutting assemblies 2 with the proper cutting strokes can be selected to be connected with the anastomat body 1.
It will be appreciated that the cutting assembly 2 is removably connected to the stapler body 1 to facilitate replacement of the cutting assembly 2. Preferably, the cutting assembly 2 is plugged with the stapler body 1.
It should be noted that, in order to automatically identify the cutting stroke of the currently inserted cutting assembly 2 after the cutting assembly 2 is inserted into the stapler body 1, at least two sets of stroke identification contacts 11 are arranged in the stapler body 1, the stroke identification contacts 11 correspond to the cutting strokes of the cutting assembly 2 one by one, that is, the stapler body 1 can be adapted to several types of cutting assemblies 2, and then a corresponding number of stroke identification contacts 11 are arranged in the stapler body 1. The stroke recognition contact 11 is connected with the controller, so that after any stroke recognition contact 11 is switched on, the cutting stroke of the cutting assembly 2 corresponding to the switched-on stroke recognition contact 11 is sent to the controller, and after a starting switch of the power device is triggered, the cutting knife of the anastomat body 1 completes the cutting action corresponding to the cutting stroke.
Meanwhile, an elastic contact 12 for contacting with the stroke recognition contact 11 to switch on the stroke recognition contact 11 is also arranged in the anastomat body 1. It will be understood that the stroke recognition contact 11 preferably comprises a fixed contact and a movable contact, and is in a normally open state, i.e. the movable contact and the fixed contact are not in contact in a normal state, and when the elastic contact piece 12 is in contact with the movable contact of the stroke recognition contact 11, the movable contact and the fixed contact can be driven to be in contact so as to send a cutting stroke signal to the controller.
It should be noted that, the cutting assembly 2 is provided with a stroke identification portion 21 for being matched and connected with the stapler body 1, and the elastic contact piece 12 can be linked with the stroke identification portion 21, that is, when the stroke identification portion 21 is installed in the stapler body 1, the stroke identification portion 21 can move and simultaneously drive the elastic contact piece 12 to move together.
The stroke recognition parts 21 correspond to the cutting strokes of the cutting assemblies 2 one by one, specifically, different stroke recognition parts 21 have different assembly lengths, and the assembly lengths of the stroke recognition parts 21 are different when the cutting strokes of the cutting assemblies 2 are different.
Therefore, when the different stroke recognition portions 21 are incorporated into the stapler body 1, the moving distances of the different stroke recognition portions 21 are different, and the moving distances of the elastic contact pieces 12 in conjunction therewith are different. Therefore, the position of the stroke recognition contact 11 may be arranged according to the assembly length of the stroke recognition part 21 so that the elastic contact piece 12 is brought into contact with the stroke recognition contact 11 corresponding to the cutting assembly 2 after the stroke recognition part 21 is assembled in place, thereby turning on the stroke recognition contact 11.
Specifically, the stroke recognition contacts 11 are arranged side by side, and the distances from the elastic contact pieces 12 to the stroke recognition contacts 11 are respectively equal to the assembly lengths of the stroke recognition parts 21 in a one-to-one correspondence manner. Therefore, when the stroke recognition portion 21 is fitted in place, the elastic contact piece 12 is surely moved in place, and the stroke recognition contact 11 corresponding to the stroke recognition portion 21 is turned on.
Preferably, the stapler body 1 in the embodiment can be adapted to three cutting assemblies 2, and the cutting strokes of the three cutting assemblies 2 are respectively 60mm, 45mm and 30 mm; correspondingly, the assembly lengths of the stroke recognition part 21 are 3.2mm, 6.2mm, and 9.2mm, respectively.
Preferably, when the cutting assembly 2 is assembled with the stapler body 1, the stroke recognition portion 21 is inserted into the end of the stapler body 1, and the assembly length of the stroke recognition portion 21 is the distance of inserting the stroke recognition portion 21 into the stapler body 1.
It should be noted that the specific structure and shape of the stroke identification portion 21 are not limited in the present invention, and the stroke identification portion 21 may be a convex ring protruding out of the cutting assembly 2 away from the jaw end, or may be other shapes such as a column or a polygon.
In summary, in the electric intracavity cutting stapler provided by the present invention, since the elastic contact 12 can be linked with the stroke recognition portion 21, when the stroke recognition portion 21 is installed in the cutting stapler, the elastic contact 12 can be driven to move together, and since the assembly lengths of the different stroke recognition portions 21 are different, the moving distance of the elastic contact 12 linked with the stroke recognition portion 21 is different, therefore, after the stroke recognition portion 21 is assembled in place, the elastic contact 12 can be moved to the stroke recognition contact 11 corresponding to the stroke recognition portion 21 to switch on the stroke recognition contact 11, so as to send the cutting stroke of the currently installed cutting assembly 2 to the controller, so that the controller controls the power device of the stapler body 1 to make corresponding operation to complete the cutting operation of the cutting knife.
Therefore, in the electric intracavity cutting anastomat, the stroke recognition part 21 corresponding to the cutting stroke is arranged on the cutting assembly 2, and the cutting stroke recognition of the cutting assembly 2 is realized in the assembling process of the stroke recognition part 21. Therefore, in the operation process, as long as the cutting assembly 2 is installed in the stapler body 1, the controller of the stapler body 1 can automatically identify the cutting stroke of the cutting assembly 2, and the controller controls the power device to operate, so as to complete the cutting process corresponding to the stroke. When different cutting strokes are needed according to human tissues, only different cutting assemblies 2 need to be switched, so that at least two cutting assemblies 2 can be adapted by only one stapler body 1 in a single operation, the medical cost is saved, and the sterilization, maintenance, management and the like of a plurality of sets of cutting staplers are avoided.
