It is mobile, and the relative position of the second tweezer tablet 12 and the 4th tweezer tablet 22 is fixed, have the function that fixed two sides vascular wall.Due to first
Screw rod 13 and the second screw rod 14 are respectively fixedly connected in the first tweezer tablet 11, the second tweezer tablet 12, by the first screw rod 13 and second
Screw rod 14 exerts a force, and can directly inside tweezer 1 exert a force, reach when keeping outer tweezer 2 to immobilize, can directly clamp 1 liang of interior tweezer
Side is expanded into blood vessel so that interior tweezer 1 is clamped, then is exerted a force by external 2 two sides of tweezer, reaches folder with the cooperation of interior tweezer 1
The effect of tight two sides vascular wall.By matching for the first screw rod 13, the second screw rod 14 and the first nut 51, the second nut 52
Conjunction uses, and is capable of the operation that one hand controls interior tweezer 1 and outer tweezer 2 simultaneously, and being used cooperatively between nut and screw rod can be more smart
The relative position between interior tweezer 1 and outer tweezer 2 really is controlled, and can be with the fixed two sides vascular wall of a fixed power, to blood vessel
Injured caused by wall it is smaller, and the interior tweezer 1 through the connection that is screwed and outer tweezer 2 cooperation clamping vascular wall, hand pair can be discharged
In the extruding force of tweezers, loosen hand more, avoids applying the muscular fatigue during art.
As the another embodiment of the utility model, the first tweezer tablet 11, the second tweezer tablet 12 tweezer head on the outside of be respectively equipped with tooth
Line 4, third tweezer tablet 21, the 4th tweezer tablet 22 tweezer head on the inside of be respectively equipped with groove 4, the first tweezer tablet 11 and third tweezer tablet 21, second
Tweezer tablet 12 is used cooperatively with the 4th tweezer tablet 22, and groove 4 matches between any two, passes through the chucking power of two sides tweezer tablet, two sides groove 4
The vascular wall that side can closely be clamped, increases the frictional force between vascular wall and tweezers, prevents vascular wall unexpected
It is detached from, so that the stability in surgical procedure is got higher, prevents vascular wall rebound caused by falling off in surgical procedure because of engagement from causing
Contingency.
As the another embodiment of the utility model, the first tweezer tablet 11, the second tweezer tablet 12 tweezer head on the outside of be respectively equipped with hook
Tooth 7, the third tweezer tablet 21, the 4th tweezer tablet 22 tweezer head on the inside of be respectively equipped with briar tooth 7, the first tweezer tablet 11 in third tweezer tablet 21
Briar tooth 7 match, the second tweezer tablet 12 matches with the briar tooth 7 in the 4th tweezer tablet 22.Briar tooth 7 between any two matches, and leads to
The chucking power for crossing two sides tweezer tablet enables two sides briar tooth 7 closely to clamp the vascular wall of side, enable tweezers more
Add the vascular wall for compactly clamping side, prevents vascular wall from undesirably falling off, so that the stability in surgical procedure is got higher, prevent hand
Contingency caused by the rebound of vascular wall caused by falling off during art because of engagement.
As the another embodiment of the utility model, the tweezer head of interior tweezer 1 and outer tweezer 2 is arcuate structure, and arcuate structure makes
The use posture for obtaining tweezers changes, and tweezers is used using tweezers with being changed into horizontal direction from vertical direction, so that tweezer
The sight that son itself will not observe blood vessel to patient causes to hinder, and arcuate structure makes some tweezer head above blood vessel,
So that blood vessel above do not have obstacle, conduit can vertical direction enter blood vessel so that in surgical procedure be inserted into conduit more hold
Easily.
As the another embodiment of the utility model, anti-skid chequer 3, the 4th tweezer tablet are equipped in the middle part of 21 outside tweezer handle of third tweezer tablet
Anti-skid chequer 3 is equipped in the middle part of 22 outside tweezer handles, anti-skid chequer 3 is netted or strip groove profile lines, and two sides anti-skid chequer 3 is when holding tweezers
The frictional force between hand and outer tweezer 2 is increased, can prevent tweezers sliding from tweezers being avoided to skid in the course of surgery, cause to perform the operation
It is unexpected.
Above specific embodiment has carried out further the purpose of this utility model, technical scheme and beneficial effects
It is described in detail, it should be understood that the above are only specific embodiments of the present invention, is not used to limit the utility model
Protection scope.It particularly points out, to those skilled in the art, within the spirit and principle of the utility model, is done
Any modification, equivalent substitution, improvement and etc., should be included within the scope of protection of this utility model.
