The suturing and cutting instrument provided by the invention has the main beneficial effects that through enhancing buffering, the toughness of the pin hole is improved, the problem that a plastic component is cracked when the plastic component and a metal piece are in the interference fit is solved, and the safety performance of the whole suturing and cutting instrument is promoted.
Description
Technical field
The present invention relates to a kind of linear seaming and cutting device, belong 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, 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 described going up on the clamp by 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, be fixedly installed on down the locating piece on the clamp, be provided with an alignment pin by the pin-and-hole structure equally on it, behind clamp about the closed handle closure, last clamp can bring pressure to bear on the described alignment pin, cause the pin-and-hole on the described locating piece that the possibility that produces cracking is also arranged, thereby bring unnecessary trouble.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, provide a kind of safety higher seaming and cutting device.
Purpose of the present invention is achieved through the following technical solutions:
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 for the closed described closed handle of clamp up and down, described closed handle is located at described going up on the clamp by pin-and-hole structure pivot, described pin-and-hole and pivotal axis interference fit offer a U-lag on the described pin-and-hole side.
Preferably, the axis of symmetry of described U-lag passes the center of described pin-and-hole.
Preferably, described pin-and-hole is hexagon, and described 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 described clamp down, and the pin-and-hole interference ground that is positioned on the described locating piece inserts an alignment pin, offers a U-lag on the pin-and-hole side on the described locating piece.
Preferably, the axis of symmetry of the U-lag on the described locating piece passes the center of described pin-and-hole.
Beneficial effect of the present invention is mainly reflected in: by increasing buffering, improved the toughness of pin-and-hole, the problem that plastic parts ftractures when having solved plastic parts and metalwork interference fit has promoted the security performance of whole seaming and cutting device.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:

Wherein:
The specific embodiment
The present invention has disclosed a kind of seaming and cutting device, 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 described closed handle 3 of clamp up and down.The same with prior art, described closed handle 3 is located at described going up on the clamp 1, described pin-and-hole 31 and pivotal axis interference fit by pin-and-hole structure pivot.Comparison diagram 2 and shown in Figure 3, characteristics of the present invention are to offer a U-lag 32 on described pin-and-hole 31 sides.Preferably, the axis of symmetry of described U-lag 32 passes the center of described pin-and-hole 31.In this preferred embodiment, described pin-and-hole 31 is hexagon, and described 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 by increasing buffering, improved the toughness of pin-and-hole, the problem of plastic parts cracking can not twist off the base portion of pin-and-hole easily when having solved plastic parts and metalwork interference fit, 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 described clamp 2 down, and the pin-and-hole 41 interference ground that is positioned on the described locating piece 4 inserts an alignment pin 5, offers a U-lag 42 equally on pin-and-hole 41 sides on the described locating piece 4.Preferably, the axis of symmetry of the U-lag on the described locating piece passes the center of described pin-and-hole.
When technology of the present invention 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, reduced the probability of plastic parts cracking, and improved package power to a certain extent, promoted stability of structure and safety.
The present invention 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 protection of present invention.
