Abstract
The invention provides a handle assembly, which comprises a gripping part and a firing connecting rod which are connected with each other, wherein the firing connecting rod comprises a butting part at the front end and a forked part at the rear end; two forks of the forked part can be opened or closed; and a circular pin is inserted into the forked part, is pivoted on the gripping part and can produce certain displacement in the forked part under the action of the gripping part. The handle assembly has the main advantage of effectively avoiding breakage of a firing handle due to continuous overlarge force by increasing buffering, and is safe and reliable.
Description
Technical field
The present invention relates to a kind of handle assembly, especially a kind of handle assembly that is applicable to the surgical operation Binding Instrument that comprises linear type closer, arc 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, the linear type closer is a kind of of outbalance.In the prior art,, put down in writing a kind of linear type closer with reference to U.S. Pat 7407076, be used for closed digestive tract and viscera tissue wound, generally comprise shell, be fixed in the support in the shell, place the nail anvil and the nail bin of rack far end, and pivot places the percussion handle on the support.Operation process is roughly as follows: at first tissue is placed between nail anvil and the nail bin, handle is pulled the trigger in extruding then, and nail bin is drawn close grip tissue to the nail anvil direction.Discharge the percussion handle then, place this moment the ejector pin mechanism in the support ready, push the percussion handle again, ejector pin mechanism is pushed out of nail bin with nail, and forms in tissue, plays closed effect.
Yet in operation process, after nail was shaped and finishes, pushing slice of nail just can't move forward again, comes squeeze handles but the doctor is continuously applied bigger power toward the contact meeting after percussion, caused the percussion handle by excessive compression, fractureed easily.
Summary of the invention
The objective of the invention is to solve above-mentioned technical problem, provide a kind of safety higher handle assembly, it can be applicable on the surgical operation Binding Instrument that comprises linear type closer, arc seaming and cutting device at least.
Purpose of the present invention is achieved through the following technical solutions:
A kind of handle assembly, comprise interconnective grip part and percussion connecting rod, described percussion connecting rod comprises the abutting part that is arranged on front end, and be arranged on the furcation of rear end, two bifurcateds of described furcation can be opened or close and close, be inserted with a round pin in the described furcation, described round pin and pivot is in described grip part again, described round pin can produce certain displacement under the effect of described grip part in described furcation.
Further, described furcation comprises the breach of being located at the percussion rod rear end, and the front end of described breach is a pin-and-hole.
Further, described pin-and-hole the place ahead is a V-shaped groove.
Further, the place ahead of described V-shaped groove is provided with elongated slot.
Further, the axis of described elongated slot extends to the front end of described percussion connecting rod.
Further, described handle assembly is applied to straight line closer or straight line seaming and cutting device or arc seaming and cutting device.
Beneficial effect of the present invention is mainly reflected in: by increasing buffering, can avoid effectively excessively causing described percussion to be fractureed with handle because of continuing to exert oneself, and safe and reliable.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Fig. 1: the structural representation of handle assembly of the present invention.
Fig. 2: the structural representation of the percussion connecting rod of handle assembly of the present invention.
Insert the structural representation of round pin in the percussion connecting rod of Fig. 3: Fig. 2.
The handle assembly of Fig. 4: Fig. 1 is assembled to the structural representation behind the linear type closer.
Wherein:
1 grip part, 11 grooves, 12 pivots
13 through holes, 2 percussion connecting rods, 21 abutting parts
22 furcations, 23 breach, 24 pin-and-holes
4 push rods, 5 shells
The specific embodiment
The present invention has disclosed a kind of handle assembly, as shown in Figure 1, comprises interconnective grip part 1 and percussion connecting rod 2.Described grip part 1 comprises a groove 11 that is applicable to ergonomics, and a pivot 12 that is used for the swing handle assembly.
Specifically as shown in Figure 2, described percussion connecting rod 2 comprises the abutting part 21 that is arranged on front end, and is arranged on the furcation 22 of rear end.Two bifurcateds of described furcation 22 can be opened or close and close, and are inserted with a round pin 3 in the described furcation 22, and the two ends of this round pin 3 extend in the through hole 13 of grip part 1 again.
In this preferred embodiment, described furcation 22 comprises the breach 23 of being located at percussion connecting rod 2 rear ends, and the front end of described breach 23 is the receiving space of accommodating described round pin 3.Described breach 23 is closed under normal condition, has only when round pin 3 is forced to move forward into furcation, just opens.Specifically, the receiving space of described furcation 22 is a pin-and-hole 24, and is located at the V-shaped groove 25 in described pin-and-hole 24 the place aheads.Round pin 3 is housed in when original state in this pin-and-hole 24.
In the normal percussion power scope that handle is subjected to, V-shaped groove 25 can not strutted.When also firmly being held down after the handle assembly percussion on earth of the present invention, round pin 3 can produce certain displacement with respect to described abutting part 21 in described furcation 22, promptly can strut V-shaped groove 25, play a buffered effect, prevent grip part 1 fracture of handle assembly.When unclamping handle, under the elastic reaction of V-shaped groove 25, round pin 3 is got back to the origin-location again, does not influence to reuse.
Further, the place ahead of described V-shaped groove 25 also can be provided with elongated slot 26, makes the elasticity of furcation 22 better like this.The axis of described elongated slot 26 extends to the front end of described percussion connecting rod 2, to guarantee the trend of round pin 3.
Handle assembly of the present invention can be applicable to comprise the surgical instruments of straight line closer or straight line seaming and cutting device or arc seaming and cutting device etc., is widely used, and is worthy to be popularized.
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.
