Abstract
A surgical cutting stapler comprises a staple holder (2), a component seat (3), an osculating component (5), an actuating device (6) and a closing device for operating the staple holder (2), wherein the osculating component (5) is mounted on the component seat (3), two positioning slots (3-1) are arranged at the head and in the middle of the component seat (3) respectively, two positioning pins (2-1) matched with the positioning slots (3-1) are arranged on the staple holder (2) respectively. When the surgical cutting stapler is used for osculating thick tissues, a staple holding portion and the osculating component can be positioned accurately, rigidity of the stapler is enhanced, and uniformity of the front stapling height and the rear stapling height and forming quality of the staple are guaranteed.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of surgery Endo-GIA.
Background technology
Endo-GIA is a kind of medical apparatus and instruments that often uses when physiological tissues such as digestive tract are performed surgical operation, but when carrying out cross-section identical excision for gastric tissue, uses to have Endo-GIA (seeing also Fig. 1) now and have following shortcoming:
When 1) performing the operation, for thicker gastric tissue, when closed compress tissue, tissue is bigger to the counter-force of apparatus, because the apparatus front end is a cantilever design, the apparatus rigidity is relatively poor, and nail supporting base can upwarp distortion, make front end coincide the height H change greatly, also skew about meeting simultaneously, it is bad to cause anastomosis staple to be shaped, and tissue can't effectively coincide, influence operation quality is brought influence to operation safety.
2) in addition for identical different tissue, because individuality or histological difference, identical height is different, in case selected apparatus, the shut height of prior art can't be adjusted, like this in clinical operation, might weigh tissue or identical highly bigger than normal wounded, influence operation quality.
3) in addition, greater than the apparatus more than the 80mm, because the percussion stroke is longer, the doctor, can make percussion process difficulty, even cause operative failure greatly the time as the percussion resistance with manual percussion the time for identical length.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of nail supporting base accurately to locate with anastomosis cut component, and the highly surgery Endo-GIA of unanimity and anastomosis staple forming quality that coincide before and after guaranteeing.
The technical scheme that realizes above-mentioned purpose is: a kind of surgery Endo-GIA, comprise nail supporting base, assembly seat, anastomosis cut component, percussion lock and the closing device of handling nail supporting base, anastomosis cut component is installed on the assembly seat, assembly seat head and middle part respectively are provided with a locating slot, and correspondingly on nail supporting base are provided with two alignment pins that cooperate with locating slot.
Handling the closing device of nail supporting base is made up of closed knob, closed screw mandrel and driving member, closed knob is connected with closed wire rod thread, the front end and the driving member of closed screw mandrel are hinged, and driving member is provided with bearing pin, and has the chute that cooperates with this bearing pin at nail supporting base.
Anastomosis cut component is made up of anastomosis staple, cutter, pushing slice of nail and driving wedge, percussion lock is electronic percussion lock, is made up of drive motors, driving screw mandrel and nut, drives screw mandrel and fixedlys connected with the main shaft of drive motors, nut is spun on and drives on the screw mandrel, and the front end of nut props up the driving wedge.
Percussion lock is provided with operating grip, and operating grip is provided with firing button, and the inner of firing button is connected on the panel, and panel is connected with drive motors by lead.
After adopting technique scheme, centre and head at assembly seat are provided with 2 locating notches, when closure, make when nail portion moves forward and backward in the groove of the front and back of assembly seat by close mechanism to move up and down, realization is to the closure of tissue, and its closed gap can be controlled by close mechanism.Anastomosis cut component packed into before the apparatus closure in the assembly seat, anastomosis staple is aimed at supported the nail groove on the nail supporting base, its quantity is corresponding one by one, and cutting assembly is finished with the driver part on the instrument body and is connected simultaneously.Behind the apparatus closing tissue,, thereby promote tiltedly to carve in the anastomosis cut component, finish coincideing and cutting physiological tissue by the driver part on the Vidacare corp driving instruments body.
By above structure, realized apparatus in that osculating is thick when organizing, support the accurate location of nail portion and anastomosis cut component, improved the apparatus rigidity, concordance and anastomosis staple forming quality highly coincide before and after having guaranteed.Use electronic percussion lock, make the percussion process be more prone to help improving the forming quality of anastomosis staple with the finishing of even speed, improved the operating characteristics of apparatus simultaneously, making has the percussion of big stroke to be more prone to realize.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail.
Shown in Fig. 2 ~ 4, a kind of surgery Endo-GIA, comprise nail supporting base 2, assembly seat 3, anastomosis cut component 5, percussion lock 6 and the closing device of handling nail supporting base 2, anastomosis cut component 5 is installed on the assembly seat 3, assembly seat 3 heads and middle part respectively are provided with a locating slot 3-1, and correspondingly on nail supporting base 2 are provided with two alignment pin 2-1 that cooperate with locating slot 3-1.
As shown in Figure 3, handling the closing device of nail supporting base 2 is made up of closed knob 1, closed screw mandrel 13 and driving member, closed knob 1 and closed screw mandrel 13 are threaded, the front end and the driving member of closed screw mandrel 13 are hinged, driving member is provided with bearing pin 14, and has the chute 15 that cooperates with this bearing pin 14 at nail supporting base 2.
As shown in Figure 3, anastomosis cut component 5 is made up of anastomosis staple 11, pushing slice of nail 10 and driving wedge cutter 9, percussion lock 6 is electronic percussion lock, form by drive motors, driving screw mandrel 7 and nut 8, driving screw mandrel 7 fixedlys connected with the main shaft of drive motors, nut 8 is spun on and drives on the screw mandrel 7, and the front end of nut 8 props up driving wedge 9.
Shown in Fig. 2,3, percussion lock 6 is provided with operating grip, and operating grip is provided with firing button 12, and the inner of firing button 12 is connected on the panel, and panel is connected with drive motors by lead.
Operation principle of the present utility model is as follows:
In apparatus of the present utility model, put into the physiological tissue 4 that will perform the operation, rotating closed knob 1, driving closed screw mandrel 13 moves, closed screw mandrel 13 drives connected driving member and moves, move in the chute 15 of the correspondence on nail supporting base 2 of the bearing pin 14 on this driving member, thereby promote nail supporting base 2 closed physiological tissues 4, because assembly seat 3 heads have nail supporting base 2 location and fixed locating slot 3-1, before shut height H is wanting grip tissue, the alignment pin 2-1 of nail supporting base 2 heads just enters in the locating slot 3-1 of assembly seat 3, continue rotating closed knob 1 compression physiological tissue 4 to the identical height that requires and make apparatus be locked in this position, by this structure, nail supporting base 2 and cutting assembly 5 are accurately located.
