The specific embodiment
This utility model has disclosed a kind of cutting binder for surgical department, as shown in Figures 1 to 4, comprises the nail bin groupware 10 and the nail-anvil assembly 20 of dismounting mutually.
In conjunction with Fig. 2 and shown in Figure 3, nail bin groupware 10 comprises nail bin 101 and the one group of pushing slice of nail 107 that sets within it movably.The curved setting of the main body of described nail bin 101, and comprise an arcuate groove 102, make the main body of nail bin 101 be hollow structure.Being that nail bin 101 comprises an arcual inner and outer wall, is an arcuate groove 102 between the two.
Nail bin 101 is disposed with nail bin hole 103 on the surface of nail-anvil assembly 20.Described nail bin hole 103 is the same with prior art, and be many rows and be provided with, in this preferred embodiment three rows, in order better to be bound effect, two adjacent rows are that dislocation is arranged, this is consistent with prior art, does not repeat them here.All be provided with a nail in each nail bin hole 103, and each nail has all connected a pushing slice of nail monomer.Because three row's nail bin holes 103 all are the arc setting, so the also curved setting of this pushing slice of nail 107.In this utility model, the pushing slice of nail monomer all is separate individuality, and a pushing slice of nail monomer promotes a suturing nail, phase mutually noninterfere.But for the convenience of assembling, the part that also the pushing slice of nail monomer can be exposed the nail bin hole couples together with light and handy structure.
Described one group of pushing slice of nail, 107 curved being arranged in the described arcuate groove 102, nail bin of reuse lid 104 seal arcuate groove 102, and assurance pushing slice of nail 107 can not drop out arcuate groove 102.
Extend a nail bin connecting rod 105 on the arc inner wall of described nail bin 101, have a trigger shaft 108 pivots to be arranged on the nail bin connecting rod 105.Described nail bin connecting rod 105 roughly is provided with a hole 106 on the centre position at it, and the middle part of described trigger shaft 108 is provided with a pin 109, and described pin 109 is arranged on and is used in the hole 106 pivoting.One end of described trigger shaft 108 is an operating portion 111, and the other end is and pushing slice of nail 107 inclined-plane 110 that connects and the cutter 112 that are fixed on this end that described cutter 112 are vertically set on the trigger shaft 108.
Described nail bin 101 towards nail-anvil assembly 20 the surface on also be provided with a curved knife groove 116, this cutter groove 116 is arranged between the two row nail bin holes 103, the arranged outside of the cutter groove 116 described in the present embodiment has two row's nail bin holes 103.
In conjunction with Fig. 2 and shown in Figure 4, nail-anvil assembly 20 comprises nail anvil 201 and is arranged on the nail forming tank 202 and the cutter groove 206 on nail anvil surface, described nail anvil 201 curved settings, and its profile and nail bin 101 are roughly the same.Nail forming tank 202 and all curved arrangement of cutter groove 206 are arranged on the nail anvil 201.The same with prior art, nail forming tank 202 is a relative set with nail bin hole 103, in the present embodiment promptly, three row's nail forming tank 202 that arc is provided with, wherein two rows are arranged on the outside of cutter groove 206.And the profile of cutter groove 206 is also roughly the same with the shape that is arranged on the curved knife groove 116 on the nail bin 101, also all is for cutter 112 are slided within it so that can cut off tissue quickly.
Be provided with a retaining mechanism between described nail bin groupware 10 and the nail-anvil assembly 20, with so that nail bin 101 and nail anvil 201 interfix.In this preferred embodiment, described retaining mechanism comprises screw rod 204 and knob 113, extend a nail anvil connecting rod 203 on the inwall of described nail anvil 201, described screw rod 204 is fixedly installed on the described nail anvil connecting rod 203, its external screw thread is threaded with knob 113 after passing through hole 114 on the nail bin connecting rod 105 that is arranged on described nail bin groupware 10.Like this, behind turn knob 113, can make nail anvil 201 and nail bin 101 relative motioies or reverse motions.
In this preferred embodiment, described nail bin 101 is provided with two alignment pins 115, is separately positioned on the two ends that nail bin 101 regards to the curved surfaces of nail anvil 201.Described nail anvil 201 is provided with two locating holes 205, is separately positioned on the two ends that nail anvil 201 regards to the curved surfaces of nail bin 101.When nail bin groupware 10 and nail-anvil assembly 20 mutual assemblings, alignment pin 115 promptly is inserted in the positioning hole corresponding 205, locks the screw rod 204 of mechanism again, and the arrangement that is triangle makes the assembling of nail bin groupware 10 and nail-anvil assembly 20 more accurate, more firm.Certainly, those skilled in the art can both know that the position of alignment pin 115 and locating hole 205 can exchange, and promptly on the nail bin 101 locating hole 205 is set, and alignment pin 115 is set on the nail anvil 201, and such change is still within protection domain of the present utility model.
As can be seen from Figure, two locating holes 205 probably are 30 degree to the angle between the line of screw rod 204, and promptly the size of angle has determined the size of the arc main body of nail bin 101 or nail anvil 201.But, this angle can be become big in order to cut and bind wider tissue.Because technology of the present utility model can manufacture the nail bin 101 or the nail anvil 201 of any size, therefore only change the technical scheme of above-mentioned corner dimension still within protection domain of the present utility model.
The once assembling and the operating process of this preferred embodiment are simply described below.
Nail anvil 201 is fixedlyed connected with nail anvil connecting rod 203, and nail bin 101 is fixedlyed connected with nail bin connecting rod 105.Install nail and pushing slice of nail 107 in the nail bin 101, cutter 112 are installed to the far-end of trigger shaft 108, cutter 112 are placed in the curved knife groove 116 of nail bin then, build nail bin lid 104 then.Trigger shaft 108 is pivotally connected on the nail bin connecting rod 105, it can be rotated with respect to nail bin 101 connecting rods.At last, the alignment pin on the nail bin 101 115 is inserted in the locating hole 205 of nail anvil 201, then nail anvil connecting rod 203 and nail bin connecting rod 105 usefulness screw rods 204 are coupled together.Described nail bin 101 and nail anvil 201 are oppositely arranged the suture zone that forms apparatus.
During operation, elder generation's counter-rotation knob 113, nail anvil 201 is separated with nail bin 101, tissue is placed on the nail anvil 201, then nail bin 101 binding surfaces also are placed into tissue, and alignment pin 115 is inserted in the locating hole 205 on the nail anvils 201, then nail anvil connecting rod 203 and nail bin connecting rod 105 usefulness screw rods 204 are coupled together, then turning knob 113, make nail anvil 201 and nail bin 101 with clamp tissue. reverse trigger shaft 108 then, trigger shaft 108 beginning is rotated with respect to nail bin connecting rod 105, thus make the inclined-plane 110 of its far-end will be stored in the nail bin 101 nails successively one by one percussion come out; Simultaneously, be connected on the trigger shaft 108 cutter 112 also in described arcuate groove 102 arching trajectory along arcuate groove move, excess tissue or tumor are cut away. well-known, such cutting mode can will be organized easier cut-out. and last, open knob 113, separate nail anvil 201 and nail bin 101, discharge tissue, withdraw apparatus, finish the cutting and binding of tissue. because nail bin, nail anvil, the nail bin hole all is into the arc setting of roughly the same curvature, therefore, it is very good to use the tumor effect that this apparatus excision is positioned at organization edge, for example the cancerous issue at pulmonary edge, only need once can be shaped by cutting and binding with this apparatus, and do not need as prior art cutting and binding twice, avoided the generation of operation sequela, surgical effect is very good.
This utility model still has multiple concrete embodiment, for example changes row's number in nail bin hole.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
