Abstract
A pen type puncture needle of artificial rupture of membranes of amniotic sac relates to a puncture needle of artificial rupture of membranes of amniotic sac and resolves the problem that the existing puncture needle of artificial rupture of membranes has low safe reliability and low successful rate when used. A needle cylinder is arranged inside a loop, the upper end penetrates through the loop to be sleeved by a needle cylinder cap, the upper end of a needle clamp is fixedly connected and communicated with the lower end of the needle cylinder, an elastic needle clamp sleeve is slidably sleeved at the lower end of the needle clamp, a spring is sleeved onto the needle clamp and positioned inside a groove, the outer wall of the lower end of the needle clamp is equipped with a first stop ring and a second stop ring from top to bottom, the first stop ring is disposed outside the elastic needle clamp sleeve, and the second stop ring is arranged inside the elastic needle clamp sleeve and is abutted to the upper end of the spring. The pen type puncture needle of artificial rupture of membranes of amniotic sac has the advantages of high safe reliability, high successful rate, accurate positioning, quick rupture of membranes, controllable needle head, convenient use and contribution to clinical popularization.
Description
Technical field
This utility model relates to a kind of puncture needle of amniotic sac artificial rupture of membranes, belongs to technical field of medical instruments.
Background technology
The obstetrician is usually capable artificial rupture of membranes in stages of labor is handled, and impels the palace mouth to open big and fetal presentation decline, but does not but have handy apparatus.At present, the obstetrician uses disposable syringe usually, but in use disposable syringe is stabbed puerpera's vaginal wall or doctor's finger easily, if use mosquito forceps, often because of the blunt rupture of membranes failure of apparatus.Generally speaking, there is the low and low problem of success rate of safety and reliability in the puncture needle of existing artificial rupture of membranes in the process of using.
The utility model content
The purpose of this utility model is for there is the low and low problem of success rate of safety and reliability in the puncture needle that solves existing artificial rupture of membranes in the process of using, and then a kind of pen type puncture needle of amniotic sac artificial rupture of membranes is provided.
The technical solution of the utility model is: the pen type puncture needle of amniotic sac artificial rupture of membranes is by the syringe medicated cap, ring set, syringe, puncture needle, hollow cone bench-type termination, the pin folder, elasticity pin chuck, spring, first baffle ring and second baffle ring are formed, described hollow cone bench-type termination is threaded with the lower end of ring set, described syringe is arranged in the ring set, and the upper end of syringe passes ring set and is contained in the syringe medicated cap, the upper end of described pin folder is affixed with the lower end of syringe and be communicated with, the lower end of described pin folder is stretched out ring set and is placed in the hollow cone bench-type termination, the lower end edge of described pin folder axially has seam, described elasticity pin chuck slip cap is contained on the lower end of pin folder, have groove on the inwall of described elasticity pin chuck, described spring housing is contained on the pin folder and is positioned at groove, be provided with first baffle ring and second baffle ring from top to bottom on the outer wall of the lower end of described pin folder, and first baffle ring is positioned at the outside of elasticity pin chuck, and it is inner and lean with the upper end of spring that second baffle ring is positioned at elasticity pin chuck.
This utility model compared with prior art has following beneficial effect: this utility model is a kind of pen type puncture needle of amniotic sac artificial rupture of membranes that utilizes the operation principle design of propelling pencil, the utlity model has the high and high advantage of success rate of safety and reliability; This utility model also has accurate positioning, rupture of membranes is rapid, syringe needle is controlled, easy to use and help the advantage of clinical expansion.
Description of drawings
Fig. 1 is an overall structure sketch map of the present utility model, and Fig. 2 is a place partial enlarged drawing of Fig. 1.
The specific embodiment
The specific embodiment one: present embodiment is described in conjunction with Fig. 1 and Fig. 2, the pen type puncture needle of the amniotic sac artificial rupture of membranes of present embodiment is by syringe medicated cap 1, ring set 2, syringe 3, puncture needle 4, hollow cone bench-type termination 5, pin folder 6, elasticity pin chuck 7, spring 8, first baffle ring 9 and second baffle ring 10 are formed, described hollow cone bench-type termination 5 is threaded with the lower end of ring set 2, described syringe 3 is arranged in the ring set 2, and the upper end of syringe 3 passes ring set 2 and is contained in the syringe medicated cap 1, the upper end of described pin folder 6 is affixed with the lower end of syringe 3 and be communicated with, the lower end of described pin folder 6 is stretched out ring set 2 and is placed in the hollow cone bench-type termination 5, the lower end edge of described pin folder 6 axially has seam 6-1, described elasticity pin chuck 7 slip caps are contained on the lower end of pin folder 6, have groove 7-1 on the inwall of described elasticity pin chuck 7, described spring 8 is sleeved on the pin folder 6 and is positioned at groove 7-1, be provided with first baffle ring 9 and second baffle ring 10 from top to bottom on the outer wall of the lower end of described pin folder 6, and first baffle ring 9 is positioned at the outside of elasticity pin chuck 7, and it is inner and lean with the upper end of spring 8 that second baffle ring 10 is positioned at elasticity pin chuck 7.
The specific embodiment two: in conjunction with Fig. 1 and Fig. 2 present embodiment is described, the elasticity pin chuck 7 of present embodiment is a caoutchouc elasticity pin chuck.The clamping better effects if so is set.Other composition is identical with the specific embodiment one with annexation.
This utility model can be pressed bottom cylinder medicated cap 1 puncture needle 4 is ejected from pin folder 6 more safely by the through amniotic sac place of vaginal wall tissue, and puncture needle 4 exposes hollow cone bench-type termination, up to the artificial rupture of membrane success.In the artificial rupture of membranes process, this utility model has been avoided the damage of puerpera's vaginal wall, and the doctor also avoids damage and infects simultaneously.
