Abstract
The utility model discloses a closing device matched with a sperm duct, which comprises a left elastic clip and a right elastic clip (1, 2) and square slide bars (3); the seat ends of the left and the right elastic clips (1, 2) are elastic square rings (4); the elastic square rings (4) are sleeved on the square slide bars (3); the device is characterized in that the lower piece chucks of the left and the right elastic clips (1, 2) are provided with double teeth (5), and the upper piece chucks thereof are provided with single teeth (6); the arc surfaces of the single teeth (6) and the double teeth (5) are locked; and the single teeth (6) of the upper piece chucks of the left and the right elastic clips (1, 2) are clamped in the spacing of the double teeth (5) of the lower piece chucks of the left and the right elastic clips (1, 2). In the closing device, because the chucks are in crossed tooth shape, the sperm duct is in a curve state in a grip, so the clamping is firm, the sperm duct is not easy to slip and displace or be relocated, thereby facilitating the improvement of the operation quality. The closing device matched with the sperm duct can be widely applied to vasovasostomy.
Description
Technical field
This utility model relates to the improvement that a kind of blood vessel is drawn close device, and specifically a kind of deferent duct coincide and draws close device.
Background technology
At present, when doing spermatic duct anastomosing operation, be to hold the location, both sides that two vascular forcepss are clamped the deferent duct anastomotic stoma by assistant doctor, undergo surgery at microscopically by the operation operating doctor again.Its deficiency is: because assistant doctor holds two clamps, hands is easy to shake, causes the displacement of clamp, causes microscopically focal length in-plane displancement, causes the visual field fuzzy, the influence operation.In order to overcome above deficiency, in operation, usually drawing close device with blood vessel replaces hands to take two clamp clamping deferent duct, this blood vessel is drawn close device, constitute by left and right elasticity folder, square slide bar, the seat end of left and right elasticity folder is the elasticity square opening, the elasticity square opening is enclosed within on the square slide bar, and under clamp position, the elasticity square opening can be clamped on the square slide bar, can not slide, owing to be that square opening is enclosed within on the square pole, so left and right elasticity folder can not rotate yet, the folder end medial surface of left and right elasticity folder is the plane, in order to the clamping blood vessel.Though it is simple in structure that this blood vessel is drawn close device, also exist not enoughly, its main deficiency is: chucking power is lower, and when the clamping deferent duct, because deferent duct toughness is big, smooth surface so it is firm to be difficult to clamping, causes that deferent duct is sliding, displacement twists outward.
Summary of the invention
It is a kind of not only simple in structure that the purpose of this utility model is to provide, and chucking power is big, and when the clamping deferent duct, the deferent duct that is not easy to skid and be shifted coincide and draws close device.
For reaching above purpose, the technical scheme that this utility model adopted is: this deferent duct coincide and draws close device, constitute by left and right elasticity folder and square slide bar, the seat end of left and right elasticity folder is the elasticity square ring, the elasticity square ring is enclosed within on the square slide bar, the following chuck that it is characterized in that left and right elasticity folder established bidentate, and the last slice chuck of left and right elasticity folder is established monodentate, and the monodentate of last slice chuck of left and right elasticity folder is stuck in the bidentate gap of following chuck of left and right elasticity folder.
This utility model is also implemented by following measure: the monodentate of last slice chuck of left and right elasticity folder is sheared the edge with the inboard of the bidentate of following chuck of left and right elasticity folder and is oblique cambered surface; The one side that the bidentate of the following chuck that the monodentate of last slice chuck of left and right elasticity folder and left and right elasticity are pressed from both sides is relative is crooked cambered surface.
The beneficial effects of the utility model are: draw close device with the blood vessel of present use and compare, because chuck is the intersection dentation, deferent duct is a curve state in the folder mouth, so, adding and hold firmly, deferent duct is difficult for skidding and being shifted, and is beneficial to improve the quality of performing the operation.Can be widely used in spermatic duct anastomosing operation.
Description of drawings

Fig. 2, be structure schematic side view of the present utility model.
Fig. 3, analyse and observe enlarged diagram along Fig. 2 A-A section for this utility model.
The specific embodiment
Make this utility model with reference to Fig. 1,2,3.This deferent duct coincide and draws close device, by a left side, right elasticity folder 1,2 and square slide bar 3 constitute, a left side, right elasticity folder 1,2 seat end is elasticity square ring 4, elasticity square ring 4 is enclosed within on the square slide bar 3, under clamp position, elasticity square ring 4 can be clamped on the square slide bar 3, can not slide, owing to be that elasticity square ring 4 is enclosed within on the square slide bar 3, so, a left side, right elasticity folder 1,2 can not rotate yet, and it is characterized in that a left side, right elasticity folder 1,2 following chuck established bidentate 5, a left side, right elasticity folder 1,2 last slice chuck is established monodentate 6, a left side, right elasticity folder 1, the monodentate 6 of last slice chuck of 2 is stuck in a left side, right elasticity folder 1, in bidentate 5 gaps of 2 following chuck.
Shear along being oblique cambered surface 7 monodentate 6 of last slice chuck of left and right elasticity folder 1,2 and the inboard of the bidentate 5 of following chuck of left and right elasticity folder 1,2, to prevent forming shearing force when the clamping deferent duct, crushes deferent duct; The bidentate 5 relative one sides that the monodentate 6 of last slice chuck of left and right elasticity folder 1,2 and left and right elasticity are pressed from both sides 1,2 following chuck are crooked cambered surface, outwards slide with the deferent duct that prevents clamping.
Claims (2)
1. a deferent duct coincide and draws close device, constitute by left and right elasticity folder (1,2) and square slide bar (3), the seat end of left and right elasticity folder (1,2) is elasticity square ring (4), elasticity square ring (4) is enclosed within on the square slide bar (3), the following chuck that it is characterized in that left and right elasticity folder (1,2) established bidentate (5), the last slice chuck of left and right elasticity folder (1,2) is established monodentate (6), and the monodentate (6) of last slice chuck of left and right elasticity folder (1,2) is stuck in bidentate (5) gap of following chuck of left and right elasticity folder (1,2).
2. deferent duct according to claim 1 coincide and to draw close device, it is characterized in that the monodentate (6) of last slice chuck of left and right elasticity folder (1,2) is sheared along being oblique cambered surface (7) with the inboard of the bidentate (5) of following chuck of left and right elasticity folder (1,2); The relative one side of bidentate (5) that the monodentate (6) of last slice chuck of left and right elasticity folder (1,2) and left and right elasticity are pressed from both sides the following chuck of (1,2) is a make-up bending cambered surface.
