Detailed description of the invention
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation,
As Fig. 3, shown in 4, a kind of anastomat light flash points out percussion lock, it comprises pointer drag hook 1, pointer 2, instruction observation window 3, travel switch 4, power supply 5, flashing control circuitry 6 and LED 7, one end of pointer drag hook 1 is arranged on the screw component 8 of anastomat, the other end of pointer drag hook 1 is flexibly connected with the middle part of pointer 2 and drives pointer 2 to swing around its one end, the other end of pointer 2 stretches into instruction observation window 3 and is mated instruction percussion operation, power supply 5, travel switch 4, flashing control circuitry 6 and LED 7 are connected formation one conductive loops successively, pointer 2 is provided with switch contact 2-1, travel switch 4 is provided with the switch contact 4-1 that matches with switch contact 2-1 to coordinate break-make conductive loops by switch contact 4-1 and switch contact 2-1.Power supply 5 can adopt lithium battery.
As shown in Figure 3, LED 7 and power supply 5 are arranged on the below of instruction observation window 3.
As shown in Fig. 1 ~ 4, a kind of anastomat, it comprises outside this anastomat light flash prompting percussion lock, also comprise nail supporting base assembly 9, anastomosis cut component, push rod 10, firing handle assembly 11, coupling assembling 12, fixed handle assembly 13, screw component 8 and adjusting nut assembly 14, one end of screw component 8 is connected with nail supporting base assembly 9 by coupling assembling 12, the other end is connected with adjusting nut assembly 14 by screw thread through after fixed handle assembly 13, anastomosis cut component comprises nail bin 15, endless knife 16 and pushing slice of nail 17, one end of push rod 10 is fixedly connected with pushing slice of nail 17, the other end is flexibly connected with firing handle assembly 11, endless knife 16 is arranged on the head end of pushing slice of nail 17, and the suturing nail in the head end of pushing slice of nail 17 and nail bin 15 abuts against, stitch pitch is left between nail supporting base assembly 9 and anastomosis cut component, one end of pointer 2 is hinged on fixed handle assembly 13, instruction observation window 3 is arranged on fixed handle assembly 13, the length of the switch contact 2-1 of pointer 2 is corresponding with the length of the indicating area on instruction observation window 3.Push rod 10 can be straight also can be curved.
Operation principle of the present invention is as follows:
When rotating adjusting nut assembly 14, screw component 8 is driven to rotate, thus drive nail supporting base assembly 9 close to nail bin 15 direction, when stitch pitch between nail supporting base assembly 9 and nail bin 15 reaches the distance pre-set, pointer 2 is extremely indicated the indicating area 3-1 of observation window 3 by pointer drag hook 1 driven rotary just by rotating adjusting nut assembly 14, when pointer 2 arrives indicating area 3-1, the switch contact 2-1 of pointer 2 just in time abuts against with the switch contact 4-1 of travel switch 4, thus travel switch 4 is connected, conductive loops obtains electric, LED 7 starts flicker, so just operator is pointed out to pull the trigger by pointer 2 on the one hand, also operator can be pointed out to pull the trigger by the LED 7 of flicker on the other hand, even if when during operation, the visual field of operative site is broad not, doctor also can know when can pull the trigger by the LED 7 flashed, when pointer 2 leaves indicating area 3-1, switch contact 2-1 leaves the switch contact 4-1 of travel switch 4, and travel switch 4 is disconnected, whole conductive loops power-off, LED 7 just stops flicker, this makes it possible to conveniently point out operator to pull the trigger by light flash, percussion is made to operate in time, improve the success rate of operation, it is special in the visual field of operative site is broad not, effect of the present invention is especially outstanding, certainly, anastomat light flash prompting percussion lock of the present invention also can be applied on the anastomat of other types.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the present invention solves are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
