Description
Technical field
This utility model relates to a kind of surgical apparatus, particularly a kind of nail supporting base assembly for tube type anastomat.
Background technology
The development of chamber mirror lower digestive tract tumor resection technology, makes the mechanical anastomosis after excising become the Focal point and difficult point of successful surgery.When open surgery, can the safe nail supporting base of anastomat being inserted digestive tract to be anastomosed and is stitched into the pocket of a satisfaction.But be difficult to do the purse string suture of a satisfaction and the nail supporting base safety of anastomat inserted the digestive tract broken ends of fractured bone to be anastomosed under endoscope-assistant surgery, the pocket of inserting a rear ligation satisfaction in addition also has higher technical difficulty.So in order to the safety of performing the operation is had to the operative incision that row one is larger after excision terminates in a lot of situation, make Wicresoft's effect of endoscope-assistant surgery greatly reduce.
For this situation, Covidien company develops OrVil
tMper os nail supporting base imbedding system, solves the technological difficulties with purse string suture of inserting of nail supporting base.But it has the pharyngeal risk damaged with throat of generation in the process inserted, and sometimes also can be damaged to the tube wall tissue of esophagus.And its consequence may be fatal after above damage generation.
The patent of numbering ZL201320198229.1 before this, devises the resist-nailed seat of anastomat that a kind of endoscope-assistant surgery is suitable for, both remained OrVil
tMthe advantage of per os nail supporting base imbedding system turn avoid in the process of inserting damages bottleneck throat and esophagus.But its design itself has again its intrinsic defect: 1, being connected and fixed of its extension rod and nail supporting base is that spring card by nail supporting base itself is intrinsic has come, if cause nail supporting base to be separated with extension rod in the process that the more loose meeting of both combinations is likely dragged under nail supporting base, tightlier can cause deviating from rear nail supporting base extension rod separation difficulty if combined.And the generation of both of these case is all very thorny.2, the main body of extension rod has plastics to form, and it extends tractive unit is that steel wire is made.Make have working of plastics breakage to cause extension rod to damage in its process be separated with nail supporting base at traction steel wire, make the main body of extension rod take out difficulty.
Utility model content
The purpose of this utility model is the difficult point in order to solve mechanical anastomosis in endoscope-assistant surgery, and a kind of nail supporting base assembly for tube type anastomat of design.
To achieve these goals, this utility model have employed following technical scheme:
A kind of nail supporting base assembly for tube type anastomat, comprise nail supporting base, nail supporting base is provided with socket pipe, socket extension rod assembly is coordinated in one end of socket pipe, the one end fits of extension rod assembly connects a drawbar extension bar, it is characterized in that: the both sides of described extension rod assembly are provided with two symmetrical slots to make way, the first intercommunicating pore and the second intercommunicating pore is provided with in the lateral symmetry of described slot to make way, described socket pipe is provided with a through through hole, and through hole is communicated with described second intercommunicating pore corresponding matching.
On the basis of technique scheme, following further technical scheme can be had:
It is spherical cylindrical extended column that described extension rod assembly comprises an one end, spheroid one end of extended column connects described drawbar extension bar, the other end of extended column is provided with the straight pin of a band vertex of a cone, described slot to make way and the first intercommunicating pore are arranged on extended column, described second intercommunicating pore is arranged on straight pin, and described straight pin blind-mate is in described assembly socket pipe.
Described drawbar extension bar is steel wire rope, and drawbar extension shank diameter is less than the diameter of described extension rod assembly.
Extension rod assembly be engaged in work in socket pipe time, through hole and the second intercommunicating pore through, run through by rope that the first connection is led to, socket pipe is fixedly connected with extension rod assembly with the through hole on socket pipe by the second connecting through hole; When extension rod assembly departs from socket pipe, only need shears be engaged in slot to make way, the rope above slot to make way be cut off, extension rod assembly can be made easily to depart from socket pipe.
Beneficial effect: this utility model structure is simple, and easy to operate, extension rod easily can depart from nail supporting base in endoscope-assistant surgery, be separated and use external force less and easily controlled, can not cause Accessory injury, decrease in harness impact, result of use is good.
