Abstract
The invention discloses a staple cartridge component of a cutting and suturing device. The staple cartridge component comprises a staple cartridge and a cutting knife, a staple pushing piece pushing suturing staples is arranged in a cavity of the staple cartridge, the cutting knife penetrates a knife groove in the middle of the staple pushing piece to be fixed on a cutting knife fixing plate, a plurality of pretightening springs are mounted between the staple pushing piece and the cutting knife fixing plate, and a cutting edge of the cutting knife is lower than a tooth face of the staple pushing piece. The staple cartridge component is supportive of suturing before cutting, perfect in tissue suturing and orderly and tear-free in incision.
Description
Technical field
The invention belongs to medical instruments field, be specifically related to a kind of nail bin groupware of stapler.
Background technology
Stapler is a kind of conventional surgical operating instrument, and it can complete stitching and cutting action simultaneously, greatly saves the surgical time, reduces amount of bleeding, improves success rate of operation.Existing stapler fixes cutter in the middle of two row's staples, and cutter move in nail supporting base direction in the same way with pushing slice of nail one under the effect of thrust, are cutting and organizing tissue apposition simultaneously.This structural advantages is that structure is simple, easy to operate, and simultaneously shortcoming cuts and organizes in stitching, and during cutter cutting, tractive tissue can affect the sewing effect of staple, occurs that staple tilts, causes staple formation poor, the easy fistula of suture.
Summary of the invention
The technical problem to be solved in the present invention is that the cutting of stapler completes with stitching simultaneously, and the problem that sewing effect is not good, provides a kind of nail bin groupware that can realize first sewing up rear cutting.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of nail bin groupware of stapler, comprise nail bin and cutter, the pushing slice of nail promoting suturing nail is provided with in nail bin cavity, cutter are fixed on cutter fixing head through the cutter groove in the middle of pushing slice of nail, be provided with the spring that several have pretightning force between pushing slice of nail and cutter fixing head, cutter blade is lower than the pushing slice of nail flank of tooth.
Described spring is stage clip, leaf spring, torsion spring.
Described number of springs is 2-5.
Described cutter pin is fixed on cutter fixing head.
Advantage of the present invention is, the spring that several have pretightning force is installed between pushing slice of nail and cutter fixing head, original state pushing slice of nail keeps balance under the effect of spring and cutter, during percussion, external force promotes cutter fixing head and pushing slice of nail advance, suturing nail is released nail bin suture tissue by ejector pin gear piece, until staple molding has been sewed up, now pushing slice of nail has been blocked by nail bin, can not move at relative nail bin; Further increasing external force, spring is compressed, and cutter fixing head moves ahead together with cutter fixed thereon and carries out cutting action; Remove external force, cutter fixing head and cutter retreat under the elastic force of spring, until cutter table terrace contact pushing slice of nail, reach balance, now, cutter blade is again lower than the pushing slice of nail flank of tooth.Nail bin groupware of the present invention is in cutting and stitching process, and pushing slice of nail first promotes suturing nail molding (stitching completes), and cutter move on, and cuts off tissue.Its structure is simple, and after stitching, the stitching of tissue is perfect, and otch is neat without tearing.
Accompanying drawing explanation
The structural representation of the nail bin groupware of Fig. 1 stapler of the present invention;
The structural representation of the nail bin groupware of Fig. 2 stapler of the present invention;
Fig. 3 is the A-A profile of Fig. 2;
Wherein, 1 nail bin, 2 cutter, 3 cutter fixing heads, 4 springs, 5 pushing slice of nail, 6 pins, 7 suturing nails, 8 boss, 9 elongated slots, 10 cutter grooves.
Detailed description of the invention
As shown in Figure 1-Figure 3, a kind of nail bin groupware of stapler, comprise nail bin 1, and be contained in pushing slice of nail 5 and the cutter 2 of nail bin 1 inside, cutter 2 are fixed on cutter fixing head 3 through the cutter groove 10 in the middle of pushing slice of nail 5, be provided with the spring 4 that several have pretightning force between pushing slice of nail 5 and cutter fixing head 3, cutter 2 blade is lower than pushing slice of nail 5 flank of tooth.
The assembly that is made up of pushing slice of nail etc. in assembling process inserts in nail bin, limits motion between the two by the boss 8 on assembly and the elongated slot 9 on nail bin.The left end that some suturing nails 7 are illustrated from figure is installed in the nail groove of nail bin, contacts with pushing slice of nail 5 gear piece inserted from right-hand member.
During use, when there being external force to promote cutter fixing head 3, pushing slice of nail 5 is to left movement, and suturing nail 7 is released nail bin suture tissue by the gear piece of pushing slice of nail, until staple molding, stitching completes.Now pushing slice of nail gear piece exposes nail bin surface a little, and pushing slice of nail is blocked by nail bin, can not move at relative nail bin.Further increasing external force, spring 4 is compressed, and pushing slice of nail 5 and nail bin 1 are to left movement relatively together with cutter 2 fixed thereon for cutter fixing head 3, and cutter 2 exceed pushing slice of nail 2 surface, start the tissue that cutting and stitching is good.When cutter fixing head 3 is to left movement, namely limited to left movement by pushing slice of nail after contacting with pushing slice of nail 5, now cut.Remove external force, cutter fixing head 3 and cutter 2 move right under the elastic force of spring 4, until cutter table terrace contact pushing slice of nail, reach balance.Now, cutter blade is again lower than the pushing slice of nail flank of tooth.
