Description
Affiliated technical field
This utility model relates to a kind of medical apparatus and instruments, is a kind of disposal tube type anastomosis with percussion and safety specifically.
Background technology
The percussion lock of one-shot tube type anastomat is that flexible handle withstands the ejector sleeve seat at present, it is moved forward, because it is stressed excessive, flexible handle can open, thereby fixed handle is split, and identical meeting is failed thus, and safety are that closure at anastomat is felt to compress with feel during to certain position, just open insurance, safety is relatively poor.
Summary of the invention
In order to overcome the deficiency of above-mentioned property use tube type anastomat existence, this utility model provides a kind of disposal tube type anastomosis percussion and safety.
The technical scheme that realizes this utility model purpose is: a kind of disposal tube type anastomosis, has connection tube, be provided with assembly and nail supporting base at the connection tube front end, the connection tube rear end is provided with the hollow fixed handle, be provided with adjusting nut at the fixed handle rear portion, be provided with leading screw in handle inside, leading screw one end is connected with adjusting nut, the other end is connected with the ejector sleeve seat, in the fixing handle arranged outside of taking part in firing handle is arranged, in order to ensure just pressing firing handle at assembly and nail supporting base reaching certain intervals, improve operation safety, be connected with safety block on fixed handle, pulling-on piece is installed on leading screw, pulling-on piece is provided with step, form convex area and concave area, when lock-out state, the safety block lower end is positioned at the convex area top, and safety block can not freely rotate, when released state, the safety block lower end enters concave area, and safety block can rotate automatically, but the firing handle synchronous movement.
All the time put forth effort on the ejector sleeve seat in order to ensure the firing handle lower end; do not cause firing handle lower end extroversion when promoting the ejector sleeve seat to be opened and break away from the ejector sleeve seat; rise and split the fixed handle shell; further: be provided with catch in ejector sleeve seat both sides; the centre is provided with boss, and the firing handle lower end is embedded between boss and the catch mutually.
Operation principle of the present utility model is: when work, adjusting nut drives leading screw and makes axial rotation, and leading screw drives pulling-on piece with side's motion.Safety block is in the convex area slippage of pulling-on piece and can not rotate, and firing handle is in the lock state.When nail supporting base and assembly were closed into certain distance, the lower end of safety block entered the concave area of pulling-on piece, makes safety block produce free rotation space, pull safety block down, but the firing handle synchronous movement is pressed firing handle, promote the ejector sleeve seat according to lever principle, finish cutting and coincide.
Disposal tube type anastomosis described in the utility model, compact to design reasonable, make two effects of its percussion and insurance more effective, can guarantee the quality of performing the operation, strengthened the safety and effectiveness of apparatus, reduce the generation of malpractice.

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
A kind of disposal tube type anastomosis as shown in Figure 1, has connection tube 1, be provided with assembly 2 and nail supporting base 3 at connection tube 1 front end, connection tube 1 rear end is provided with hollow fixed handle 4, be provided with adjusting nut 5 at fixed handle 4 rear portions, be provided with leading screw 6 and ejector sleeve seat 7 in fixed handle 4 inside, leading screw 6 one ends are connected with adjusting nut 5, the other end is connected with ejector sleeve seat 7, in fixed handle 4 arranged outside firing handle 8 is arranged, and is connected with safety block 10 on the fixed handle 4, pulling-on piece 9 is installed on leading screw 6, as Fig. 4, shown in Figure 5, pulling-on piece 9 is provided with step, forms convex area 9-1 and concave area 9-2.Ejector sleeve seat 7 both sides are provided with catch 7-1, and the centre is provided with boss 7-2, and as Fig. 2, shown in Figure 3, firing handle 8 lower ends are embedded between catch 7-1 and the boss 7-2 mutually.
During use, rotate adjusting nut 5, make leading screw 6 drive pulling-on piece 9 and move, convex area 9-1 and concave area 9-2 are set on the pulling-on piece 9, more accurate when safety block 9-2 is opened.When nail supporting base 3 and assembly 2 be closed to can require apart from the time, the lower end of safety block 10 moves to the concave area 9-2 of pulling-on piece, can pull safety block 10 down this moment, firing handle 8 just can be pressed, and makes thrust on ejector sleeve seat 7.The both sides of ejector sleeve seat 7 are provided with catch 7-1, and the bottom is provided with boss 7-2, make firing handle 8 lower ends be unlikely outside spreading like this, and make fixed handle 4 crackings.
