Description
Technical field
This utility model relates to a kind of linear seaming and cutting device, belongs to medical instruments field.
Background technology
At present, physiological tissues such as esophagus, stomach, intestinal are carried out surgical operation when coincideing, often use the surgical operation Binding Instrument to coincide, wherein, linear seaming and cutting device is a kind of of outbalance.In the prior art; One Chinese patent application CN201010253352 has put down in writing a kind of linear seaming and cutting device, is used for closed digestive tract and viscera tissue wound, generally comprises clamp up and down; Nail bin and nail anvil about being located at respectively on the clamp, and be used for the closed closed handle of clamp up and down.Described closed handle is located at said going up on the clamp through pin-and-hole structure pivot, but owing to the pin-and-hole of this closed handle behind the closed clamp up and down bears bigger torsion, is easy to make the base portion of this pin-and-hole to twist off.
In addition; Fixedly install the locating piece on the infra clamp; Be provided with an alignment pin through the pin-and-hole structure equally on it, behind clamp about the closed handle closure, last clamp can bring pressure to bear on the said alignment pin; Cause the pin-and-hole on the said locating piece that the rimose possibility of generation is also arranged, thereby bring unnecessary trouble.
The utility model content
The purpose of this utility model is to solve above-mentioned technical problem, provides a kind of safety higher seaming and cutting device.
The purpose of this utility model realizes through following technical scheme:
A kind of seaming and cutting device; Comprise clamp up and down; Nail bin and nail anvil about being located at respectively on the clamp, and be used for the closed said closed handle of clamp up and down, said closed handle is located at said going up on the clamp through pin-and-hole structure pivot; Said pin-and-hole and pivotal axis interference fit offer a U-lag on the said pin-and-hole side.
Preferably, the axis of symmetry of said U-lag passes the center of said pin-and-hole.
Preferably, said pin-and-hole is a hexagon, and said U-lag is opened in one of them drift angle place of pin-and-hole.
Preferably, the seaming and cutting device comprises that one is fixed on the locating piece on the said clamp down, and the pin-and-hole interference ground that is positioned on the said locating piece inserts an alignment pin, offers a U-lag on the pin-and-hole side on the said locating piece.
Preferably, the axis of symmetry of the U-lag on the said locating piece passes the center of said pin-and-hole.
The beneficial effect of this utility model is mainly reflected in: through increasing buffering, improved the toughness of pin-and-hole, the rimose problem of plastic parts when having solved plastic parts and metalwork interference fit has promoted the security performance of whole seaming and cutting device.

Wherein:
The specific embodiment
This utility model has disclosed a kind of seaming and cutting device, and is as shown in Figure 1, comprises clamp 1 and following clamp 2, nail bin and nail anvil about being located at respectively on the clamp, and be used for the closed said closed handle 3 of clamp up and down.The same with prior art, said closed handle 3 is located at said going up on the clamp 1, said pin-and-hole 31 and pivotal axis interference fit through pin-and-hole structure pivot.Comparison diagram 2 is with shown in Figure 3, and the characteristics of this utility model are to offer a U-lag 32 on said pin-and-hole 31 sides.Preferably, the axis of symmetry of said U-lag 32 passes the center of said pin-and-hole 31.In this preferred embodiment, said pin-and-hole 31 is a hexagon, and said U-lag 32 is opened in one of them drift angle place of pin-and-hole.
Like this, behind the closed clamp up and down, the pin-and-hole 31 of this closed handle 3 is through increasing buffering; Improved the toughness of pin-and-hole; The rimose problem of plastic parts when having solved plastic parts and metalwork interference fit can not twist off the base portion of pin-and-hole easily, has promoted the security performance of whole seaming and cutting device.
Preferably; In conjunction with Fig. 4 and shown in Figure 5; The seaming and cutting device comprises that one is fixed on the locating piece 4 on the said clamp 2 down, and the pin-and-hole 41 interference ground that is positioned on the said locating piece 4 inserts an alignment pin 5, offers a U-lag 42 equally on pin-and-hole 41 sides on the said locating piece 4.Preferably, the axis of symmetry of the U-lag on the said locating piece passes the center of said pin-and-hole.
When the technology of this utility model can be used for the pin-and-hole structure interference fit of all plastic parts and metalwork; Offer a U-lag on the pin-and-hole with plastic parts; Improved the toughness of plastic parts; Reduce the rimose probability of plastic parts, and improved package power to a certain extent, promoted stability of structure and safety.
This utility model still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming all drop within the scope of this utility model requirement protection.
