Description
Technical field
This utility model belongs to medical instruments field, in particular to a kind of self-locking extended type linear cutting anastomat.
Background technology
In prior art, the postoperative the most frequently used substitute organ of Esophagectomy is " stomach ", conventionally selects " full stomach " for esophagus.Traditional " stomach is for esophagus " has many advantages, widely accepted for a long time by thoracic surgeon.Yet " full stomach is for esophagus " exists postoperative breast flatulence to occupy thoracic cavity, affects the heart, pulmonary function; The complication such as while fistula of operative incision, anastomotic stricture, reflux esophagitis are higher.These shortcomings are seriously perplexing thoracic surgery clinicist, are also having a strong impact on the quality of life after operation in patients.The excision of line cutting stitching instrument lesser gastric curvature side is implemented in Patients With Carcinoma of Esophagus operation, with tubulose stomach, rebuilds upper digestive tract.It is good that postoperative patient recovers, good results, and complication reduces greatly.When generic linear Endo-GIA coincide to tubulose stomach operation cutting, there is cross-cut, repeat the defect sewed up.By increasing the length of train wheel bridge, lower plate and nail bin, this utility model has existed while having solved cross-cut repeats to sew up, and has overcome the defect that generic linear Endo-GIA exists.Yet, because the length of train wheel bridge, lower plate and nail bin increases, when operation, between upper and lower clamping plate, clamp tissue, because tissue has elasticity, upper and lower clamping plate far-end is opened, while causing cutting and stitching, the molding of far-end anastomosis staple is bad.In order to overcome above-mentioned defect, the front end of the self-locking extended type linear cutting anastomat in this utility model arranges self-locking structure, has avoided upper and lower clamping plate far-end to open, and has guaranteed surgical effect.
Summary of the invention
The purpose of this utility model is to provide a kind of self-locking extended type linear cutting anastomat, solves cross-cut, repetition suture defects that generic linear Endo-GIA exists.
For achieving the above object, the technical solution adopted in the utility model is:
A self-locking extended type linear cutting anastomat, comprises cover plate 1, handspike 2, nail supporting base handle 3, lower cover 4, middle clamp plate 5, locating shaft 6, cutter 7, lower plate 8, train wheel bridge 9, hook 10, nail bin 11 and supports ailhead 12; On nail supporting base handle 3, be provided with slidably the handspike 2 moving for controlling cutter 7, handspike 2 is fixedly connected with cutter 7; Middle clamp plate 5 is fixed on lower cover 4, and nail supporting base handle 3 is fixed on train wheel bridge 9, is provided with locating shaft 6 on train wheel bridge 9, and middle clamp plate 5 has hook portion; One end of lower cover 4 and cover plate 1 are hinged, and cover plate 1 is fixedly connected with lower plate 8; The end of train wheel bridge 9 has a mandrel, and support ailhead 12 and there is the hole coordinating with described mandrel, between described mandrel and described hole, be interference fit; One end of lower plate 8 has breach, on nail bin 11, is provided with boss, described breach and described boss engagement connection; The length of train wheel bridge 9, lower plate 8 and nail bin 11 is 150mm; Support ailhead 12 and comprise groove; Lower plate 8 locks by self-locking mechanism with supporting ailhead 12, described self-locking mechanism by link up with 10 and described groove form, hook 10 is connected with lower plate 8 by bonding mode.
Because technique scheme is used, this utility model compared with prior art has following advantages: the length of train wheel bridge, lower plate and nail bin lengthens, by self-locking mechanism, avoided the distortion of the stressed rear generation of far-end of train wheel bridge, lower plate and nail bin, effectively guarantee anastomosis staple molding.

The specific embodiment
As shown in Figure 1, a kind of self-locking extended type linear cutting anastomat, comprises cover plate 1, handspike 2, nail supporting base handle 3, lower cover 4, middle clamp plate 5, locating shaft 6, cutter 7, lower plate 8, train wheel bridge 9, hook 10, nail bin 11 and supports ailhead 12.On nail supporting base handle 3, be provided with slidably the handspike 2 moving for controlling cutter 7, handspike 2 is fixedly connected with cutter 7.
As shown in Figure 2, middle clamp plate 5 is fixed on lower cover 4, and nail supporting base handle 3 is fixed on train wheel bridge 9, is provided with locating shaft 6 on train wheel bridge 9.Middle clamp plate 5 has hook portion, and locating shaft 6 can insert in hook portion.One end of lower cover 4 (along one end of Fig. 1 right direction) and cover plate 1 are hinged, and lower cover 4 is liftable and press down, described in to lift and press down be the process that lower cover 4 rotates around cover plate 1.Cover plate 1 is fixedly connected with lower plate 8.While instantly depressing cover plate 4, lower cover 4 drives middle clamp plates 5 to rotate, and because the hook portion front end of middle clamp plate 5 has inclined-plane, thereby the rotation of middle clamp plate 5 inserts in the hook portion of middle clamp plates 5 locating shaft 6, and then realizes the pressing of train wheel bridge 9 and 8 liang of parts of lower plate.
As shown in Figure 3, the end of train wheel bridge 9 has a mandrel, supports ailhead 12 and has the hole coordinating with described mandrel, and the mandrel of train wheel bridge 9 is inserted and supported in the hole of ailhead 12, by the interference fit between described mandrel and described hole, by train wheel bridge 9 and to ailhead 12, link together.
As shown in Figure 4, lower plate 8 front ends (along one end of Fig. 4 right direction) have breach, on nail bin 11, are provided with boss, described breach and described boss engagement connection.
Fig. 5 is the sewing effect contrast schematic diagram of generic linear Endo-GIA and self-locking extended type linear cutting anastomat.As shown in the left hand view of Fig. 5, generic linear Endo-GIA otch and suture location are intersected, and form and overlap, to the dual pressurization of local organization.Cause necrosis.As shown in the right part of flg of Fig. 5, otch and the suture location of self-locking extended type linear cutting anastomat are straight line, have avoided intersection, have overcome the defect that generic linear Endo-GIA exists.
The defect existing in order to overcome common Endo-GIA, the self-locking extended type linear cutting anastomat in this utility model lengthens the length of train wheel bridge 9, lower plate 8 and nail bin 11, and the length after lengthening is 150mm.Yet, caused thus new problem: because length increases, overall structure becomes overarm, the stressed rear generation distortion of far-end of train wheel bridge 9, lower plate 8 and nail bin 11, while causing cutting and stitching, the molding of far-end anastomosis staple is bad.
As shown in Figure 6, for fear of occurring the problems referred to above, support ailhead (12) and comprise groove; Lower plate (8) locks by self-locking mechanism with supporting ailhead (12), and described self-locking mechanism, by linking up with (10) and described groove forms, is linked up with (10) and is connected with lower plate (8) by bonding mode.By pressing down lower plate 8, the front end of hook 10 is inserted and supported in the groove of ailhead 12, then lower plate 8 is touched forward, drive the further oblique cutting of front end of hook 10 to enter in the groove of ailhead 12, so, can realize lower plate 8 and support the locking between ailhead 12.During release, reverse operating.
In this utility model, except the mode of clearly recording, the fixed form between parts is all the usual manners in this area, and as riveted joint, bonding and engaging, aforesaid way is well-known to those skilled in the art.
