Preferably, above-mentioned surgical operating instrument is chamber mirror stapler.
Incorporated by reference to Fig. 1 with reference to figure 2, Fig. 3, Fig. 4 and Fig. 5, Fig. 2 is the view when cutter in nail kit assembly when end effector in the surgical operating instrument that provides in this utility model embodiment cuts are contained in nail bin; Fig. 3 does not carry out cutting and the view of cutter when the driving backspin of push broach bar goes to cut state in nail kit assembly for end effector in the surgical operating instrument that provides in this utility model embodiment; Fig. 4 carries out the view when cutter cut in rear nail kit assembly are contained in nail bin for end effector in the surgical operating instrument that provides in this utility model embodiment; Fig. 5 is fit structure schematic diagram when end effector in the surgical operating instrument that provides in this utility model embodiment cuts between ejector pin slide block and nail bin.
In the nail kit assembly of the end effector that this utility model embodiment provides, as shown in Figure 1, above-mentioned nail kit assembly 1 comprises nail bin 14, ejector pin slide block 12 and cutter 11; Wherein:
Ejector pin slide block 12 can along nail bin 14 nearside one end distad an extreme direction be installed on nail bin 14 slidably;
As shown in Fig. 2 ~ Fig. 5, cutter 11 are positioned at the cutter groove 141 that nail bin 14 is provided with, and cutter 11 deviate from one end that nail bin 14 goes out to follow closely face is articulated in ejector pin slide block 12 by bearing pin 13, and the axial line of bearing pin 13 is vertical with cutter groove 141, cutter 11 are the pushing surface offseted with the push broach bar 3 of surgical operating instrument towards the end face of nearside; Elastic reset part 15 is provided with between cutter 11 and ejector pin slide block 12, the blade of cutter is not subject to be contained in the cutter groove 141 of nail bin 14 under elastic reset part 15 active force during the thrust of push broach bar 3 at cutter 11, and cutter 11 can rotate to cut state along bearing pin 13 when the thrust by push broach bar 3.
In above-mentioned nail kit assembly, as shown in Figure 5, cutter 11 are arranged in the cutter groove 141 of nail bin 14, and cutter 11 deviate from one end that nail bin 14 goes out to follow closely face is articulated in ejector pin slide block 12 by bearing pin 13, the elastic reset part 15 arranged between cutter 11 and ejector pin slide block 12; As shown in Figure 2, cutter 11 are not when being promoted by the push broach bar 3 of surgical operating instrument, and its blade is housed in nail bin 14 by cutter 11 under the effect of elastic reset part 15, hurt operator to prevent cutter 11 when nail kit assembly 1 is installed; As shown in Figure 3, when surgical operating instrument is when carrying out cutting and stitching, first, drive the nail-anvil assembly 2 of end effector closed tissue to be clamped with nail kit assembly 1 by corresponding driven unit, then, push broach bar 3 distal direction is driven to move the pushing surface of the distal face of push broach bar 3 and cutter 11 is offseted, and the reset force that cutter 11 overcome elastic reset part 15 under the promotion of push broach bar 3 rotates to cut state around the bearing pin 13 between cutter 11 and nail bin 14, the blade of cutter 11 is made to screw out nail bin 14; Then, drive push broach bar 3 to continue distal direction and move, the thrust of push broach bar 3 is passed to ejector pin slide block 12 by cutter 11, cutter 11 be communicated with ejector pin slide block 12 together distal direction move, to realize the cutting and stitching to tissue; As shown in Figure 4, after cutting and stitching completes, push broach bar 3 proximal direction under the driving of respective drive assembly moves and resets, simultaneously, cutter 11 rotate around the bearing pin 13 between cutter 11 and ejector pin slide block 12 under the reset force of elastic reset part 15, until the blade collecting of cutter 11 is in nail bin 14, prevent the blade of cutter 11 from causing damage to tissue, meanwhile, prevent operator from coming to harm when changing nail kit assembly 1.
Therefore, in above-mentioned nail kit assembly, can change cutter 11 when nail bin 14 is changed simultaneously, the cutter 11 of each nail kit assembly 1 use once, the sharpness of cutter 11 blade when ensure that surgical operating instrument is performed the operation, thus improve surgical quality, reduce medical-risk.
Meanwhile, the end effector with above-mentioned nail kit assembly 1 only need carry out replacing to above-mentioned nail kit assembly 1 and can realize changing nail bin 14 and cutter 11, and other parts in end effector except nail kit assembly 1 can be reused.Therefore, above-mentioned nail kit assembly 1 can either ensure the sharpness of cutter 11, and parts as much as possible in end effector can be made again to reuse, and saves product cost, improves the utilization rate of parts.
In a kind of preferred implementation, nearside one end of nail bin 14 is coordinated by flexible limit mechanism with between ejector pin slide block 12.
The setting of flexible limit mechanism, cutter 11 can be enable to go to cut state when just contacting with push broach bar 3 at the prerequisite backspin not promoting ejector pin slide block 12, when cutter 11 rotate to cut state, push broach bar 3 continues distal direction and moves, now the power of push broach bar 3 is passed to ejector pin slide block 12 by cutter 11, until ejector pin slide block 12 departs from spacing between ejector pin slide block 12 and nail bin 14 of flexible limit mechanism, promote ejector pin slide block 12 distal direction and move.
Preferably, as shown in Figure 5, above-mentioned flexible limit mechanism comprises:
Be arranged at the flexible projection 142 in the cutter groove 141 of nail bin 14;
Be arranged at the stopper slot of ejector pin slide block 12, flexible projection 142 stretches in stopper slot spacing with what realize between ejector pin slide block 12 and nail bin 14.
Certainly, the flexible limit mechanism between nail bin 14 and ejector pin slide block 12 can also be other structures, repeats no more here.
On the basis of the respective embodiments described above, the elastic reset part 15 between cutter 11 and ejector pin slide block 12 can have multiple choices:
As shown in Figure 6, elastic reset part 15 can be spring, and one end of spring is installed on ejector pin slide block 12, and the other end is installed on cutter 11.
As shown in Figure 7, elastic reset part 15 can also be shell fragment, and a bullet wall of shell fragment is connected with ejector pin slide block 12, and another plays wall and is connected with cutter 11.
Obviously, those skilled in the art can carry out various change and modification to this utility model embodiment and not depart from spirit and scope of the present utility model.Like this, if these amendments of the present utility model and modification belong within the scope of this utility model claim and equivalent technologies thereof, then this utility model is also intended to comprise these change and modification.
