Abstract
The invention discloses a kind of nail bin groupwares of stapler, including nail bin and cutter, the pushing slice of nail for pushing suturing nail is provided in nail bin cavity, the cutter groove that cutter pass through among pushing slice of nail is fixed in cutter fixed plate, several springs for having pretightning force are installed, cutter blade is lower than the pushing slice of nail flank of tooth between pushing slice of nail and cutter fixed plate.The present invention can be sutured first and be cut afterwards, and the suture of tissue is perfect, and notch is neatly without tearing.
Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of nail bin groupware of stapler.
Background technique
Stapler is a kind of common surgical operating instrument, it can be completed at the same time suture and cutting action, significantly
The surgical time is saved, amount of bleeding is reduced, improves success rate of operation.Existing stapler is solid among two rows of staples
A fixed cutter, cutter move under the action of thrust with the resist-nailed seat direction in the same direction of pushing slice of nail one, same to tissue suture
When cut tissue.This structural advantages are that structure is simple, easy to operate, the disadvantage is that in suture while cutting tissue, cutter are cut
Tissue is pulled when cutting will affect the sewing effect of staple, staple inclination occurs, causes staple formation poor, the easy fistula of suture.
Summary of the invention
The technical problem to be solved by the present invention is to the cuttings of stapler to be completed at the same time with suture, and sewing effect is bad
Problem, providing a kind of may be implemented first to suture the nail bin groupware cut afterwards.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that: a kind of nail bin group of stapler
Part, including nail bin and cutter, the pushing slice of nail for pushing suturing nail is provided in nail bin cavity, and cutter pass through among pushing slice of nail
Cutter groove is fixed in cutter fixed plate, several springs for having pretightning force are equipped between pushing slice of nail and cutter fixed plate,
Cutter blade is lower than the pushing slice of nail flank of tooth.
The spring is pressure spring, leaf spring, torsional spring.
The number of springs is 2-5.
The cutter are fixed in cutter fixed plate with pin.
It is an advantage of the invention that being equipped with several springs for having pretightning force between pushing slice of nail and cutter fixed plate, just
Beginning state pushing slice of nail keeps balance under the action of spring and cutter, and external force pushes cutter fixed plate and pushing slice of nail when percussion
Advance, suturing nail is released nail bin and sutures tissue by ejector pin gear piece, until staple formation suture is completed, pushing slice of nail is kept off by nail bin at this time
It firmly, cannot be in opposite cartridge movement；External force is further increased, spring compressed, and cutter fixed plate is together with being fixed thereon
Cutter, which move ahead, carries out cutting action；External force is removed, cutter fixed plate and cutter retreat under the elastic force of spring, until cutting
Cutter step face contact pushing slice of nail, reaches balance, at this point, cutter blade is lower than the pushing slice of nail flank of tooth again.Nail bin group of the invention
Part is in cutting sewing process, and pushing slice of nail first pushes suturing nail molding (suture is completed), and cutter move on, and cut off tissue.
Its structure is simple, and after suture, the suture of tissue is perfect, and notch is neatly without tearing.
Detailed description of the invention
The structural schematic diagram of the nail bin groupware of Fig. 1 stapler of the present invention；
The structural schematic diagram of the nail bin groupware of Fig. 2 stapler of the present invention；
Fig. 3 is the A-A sectional view of Fig. 2；
Wherein, 1 nail bin, 2 cutter, 3 cutter fixed plates, 4 springs, 5 pushing slice of nail, 6 pins, 7 suturing nails, 8 boss, 9
Elongated slot, 10 cutter grooves.
Specific embodiment
As shown in Figure 1-Figure 3, a kind of nail bin groupware of stapler, including nail bin 1, and inside nail bin 1
Pushing slice of nail 5 and cutter 2, the cutter groove 10 that cutter 2 pass through among pushing slice of nail 5 are fixed in cutter fixed plate 3, pushing slice of nail 5
Several springs 4 for having pretightning force are installed between cutter fixed plate 3,2 blade of cutter is lower than 5 flank of tooth of pushing slice of nail.
It is inserted into nail bin in assembling process by the component that pushing slice of nail etc. forms, by the boss 8 and nail bin on component
Elongated slot 9 limit movement between the two.Several suturing nails 7 out of, the left end illustrated in figure is installed to nail bin nail slot, with from
5 gear piece of the pushing slice of nail contact of right end insertion.
In use, pushing slice of nail 5 moves downward when there is external force to push cutter fixed plate 3, the gear piece of pushing slice of nail will be sutured
Nail 7 releases nail bin and sutures tissue, until staple formation, suture is completed.The nail bin surface of pushing slice of nail gear piece exposing at this time is a little, ejector pin
Piece is blocked by nail bin, cannot be in opposite cartridge movement.Further increase external force, spring 4 is compressed, cutter fixed plate 3 together with
The cutter 2 being fixed thereon are moved downward with respect to pushing slice of nail 5 and nail bin 1, and cutter 2 exceed 2 surface of pushing slice of nail, start to cut
The tissue sutured.When cutter fixed plate 3 moves downward, and moved downward by pushing slice of nail limitation after 5 face contact of pushing slice of nail,
Cutting is completed at this time.External force is removed, cutter fixed plate 3 and cutter 2 move right under the elastic force of spring 4, until cutting
Knife step face contact pushing slice of nail, reaches balance.At this point, cutter blade is lower than the pushing slice of nail flank of tooth again.
