The purpose of this utility model is achieved through the following technical solutions:
The tubular type binding instrument, comprise Binding Instrument body, crimp head, firing lock and driving regulating mechanism, the outermost layer of Binding Instrument body is a shell, firing lock comprises handle and ejector pin bar, it is characterized in that: be provided with the anti-secondary firing lock that the firing lock that can stop this Binding Instrument is pulled the trigger once more between described ejector pin bar and the shell.
The purpose of this utility model can also come further to realize by the following technical programs:
Above-mentioned tubular type binding instrument, wherein, described anti-secondary firing lock is, a place is provided with pin or lug, corresponding boss or the hole of being provided with, an other place in the middle of ejector pin bar and the shell.Or,
The ejector pin bar is provided with spring leaf, the corresponding boss that is provided with in an other place with the central place of shell, and an end of described spring leaf is fixedlyed connected with ejector pin bar or shell.Or,
Ejector pin bar outside is with an axle sleeve, the ejector pin bar is provided with a through hole, two pins are equipped with in through hole inside, a compression spring is arranged between two pins, the outer end of these two pins is resisted against the inwall of described axle sleeve under the original state, and the inwall of described shell is provided with the reducing step, the minimum diameter of reducing step becomes interference fit with the external diameter of described axle sleeve, and a side of reducing step is provided with grab.
This utility model is by being provided with the structure of pin and boss or hole, lug and boss or various ways such as hole, spring leaf and boss between ejector pin bar and shell, making this instrument to stop is automatically pulled the trigger once more, play the technique effect of anti-secondary percussion, thereby avoid damaging binder ring because of maloperation in doctor's operation process.This apparatus structure is simple and practical, and few, the easy assembling of part is easy to use, the security performance height.

The specific embodiment
This utility model surface structure as shown in Figure 1.In the prior art, be provided with drag hook between the handle 14 of this type of medical apparatus and instruments and ejector pin bar 13 afterbodys, for reaching the purpose of anti-secondary percussion, the simplest way is this drag hook of cancellation, as shown in Figure 2, but this way can make the overall package of instrument be affected, and difficulty increases, therefore, anti-secondary firing lock need be set specially on the instrument internal structure.For this reason, this utility model is conceived to the critical piece of tool housing and instrument firing lock---and the ejector pin bar has proposed a plurality of specific embodiment under the situation of whole thinking unanimity.
Among Fig. 3 a, shell 1 inside is provided with hole 5, and pin 3 is put in perforate on the ejector pin bar 2 in the hole, and the afterbody of pin 3 is equipped with spring 4; Among Fig. 3 b, shell 1 inside is provided with boss 6, and pin 3 is put in perforate on the ejector pin bar 2 in the hole, and the afterbody of pin 3 is equipped with spring 4; Among Fig. 3 c, lug 7 is put in shell 1 perforate in the hole, and the afterbody of lug 7 is equipped with spring 8, and boss 9 is set above the ejector pin bar 2; Among Fig. 3 d, shell 1 perforate, the inboard spring leaf 10 of placing, screw 11 passes perforate one end of spring leaf 10 is locked on the shell, simultaneously, boss 12 is set on ejector pin bar 2.Like this, this Binding Instrument in use, ejector pin bar reach, under boss, lug, pin, the isostructural mating reaction in hole, the ejector pin bar is stuck and can not resets, thereby plays the effect of pulling the trigger once more of preventing.
Fig. 4 a, 4b, 4c express another embodiment of this utility model: ejector pin bar 22 outsides are with an axle sleeve 23, ejector pin bar 22 is provided with a through hole, two pins 24a, 24b are equipped with in through hole inside, a compression spring 25 is arranged between two pins, the inwall of shell 21 is provided with the reducing step, the minimum diameter of reducing step becomes interference fit with the external diameter of axle sleeve 23, and, be provided with several grabs 26 in a side of reducing step.Under the original state, the outer end of pin 24a and 24b is resisted against the inwall of axle sleeve 23, shown in Fig. 4 a; When instrument was pulled the trigger, ejector pin bar 22 had been with axle sleeve 23 reaches, and after percussion was finished, axle sleeve 23 was blocked by grab 26, and pin 24a and 24b eject under the effect of spring 25, are against the outstanding position of shell 21, shown in Fig. 4 b; After unclamp handle, ejector pin bar 22 resetted, pin 24a and 24b continued to eject, and are against the recessed position of shell 21, shown in Fig. 4 c.At this moment, pin 24a and 24b and spring 25 work to prevent the secondary percussion jointly.
In addition, in four kinds of embodiments shown in Fig. 3 a/3b/3c/3d, SR is set above the tool housing outside, jammed ejector pin bar is resetted, so that operative doctor is tried out.In Fig. 4 a/4b/4c, two pins preferably have a place to fixedly connected with the contact jaw of spring, help the instrument overall package like this.
Above-mentioned specific embodiment only is a prominent example of using technical solutions of the utility model, and all technical schemes of taking to be equal to replacement or equivalent transformation and forming all drop within the claimed scope of this utility model.
