Description

Artificial ruptured membrane finger cuffs for obstetrics and gynecology

technical field

The utility model relates to the technical field of medical devices, in particular to an artificial membrane rupture finger cuff for obstetrics and gynecology.

Background technique

Artificial rupture of membranes is one of the common medical interventions used in obstetrics and gynecology to promote labor. At present, the most commonly used tool for this operation in clinical practice is a puncture needle, which is an ordinary medical needle. The specific operation process is: medical staff gloves and sanitary rubber gloves, and then use the middle finger and index finger to hold the puncture needle and probe into the birth canal. The appropriate location and timing of membrane puncture are determined, and then the thumb pushes the puncture needle firmly to expose the fingertips, and gently scratches the amniotic membrane with the needle tip to achieve membrane rupture. Although the manual rupture of the membrane with a hand-held puncture needle can successfully achieve the rupture of the membrane, the operation is troublesome, and pushing the puncture needle with a finger can easily cause the puncture needle to deviate, which greatly affects the accuracy of the diagnosis and the sensitivity of the operation. The sharp needle will also cause damage to the birth canal and increase the chance of iatrogenic infection, so we propose an artificial perforation finger cuff for obstetrics and gynecology to solve the above-mentioned problems.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to FIGS. 1-3 , the present utility model provides a technical solution: an artificial membrane perforation finger cuff for obstetrics and gynecology, including a finger cuff body 1, the finger cuff body 1 is a rubber transparent material, and the finger cuff body 1 has elasticity, so When the finger cover body 1 is placed on the thumb cover, the finger cover body 1 can be bound to the thumb under the elastic force of the finger cover body 1. The finger cover body 1 is provided with a finger cover groove 2, and the finger cover groove 2 is fixed inside A fixed seat 3 is installed, a moving chamber 4 is arranged on the fixed seat 3, a moving plate 5 is slidably connected in the moving chamber 4, and pulleys 14 are fixedly installed on both sides of the moving plate 5, and both sides of the moving chamber 4 are The guide rail 15 is fixedly installed, and the pulley 14 is slidably connected with the guide rail 15. The function of the pulley 14 and the guide rail 15 is to limit the movement of the moving plate 5 to be a linear motion. The top of the moving plate 5 is fixedly installed with a needle 6, and the outside of the needle 6 is provided with The scale, and the range of the scale is between 0.3 cm and 0.6 cm, to avoid the long length of the puncture needle 6 and injury to the birth canal of the puerperium. , a rotating hole is opened on the inner wall of the top of the moving chamber 4, and a linear bearing is fixedly installed in the rotating hole. When the body 1 is extended, under the limit of the linear bearing, the protruding needle 6 will not deviate, which reduces the error of operation;

The top of the moving plate 5 is fixedly installed with two return springs 7, and the needle 6 is located between the two return springs 7, and the tops of the two return springs 7 are fixedly connected to the top inner wall of the mobile chamber 4. After the membrane is ruptured , the thumb releases the pressing on the push plate 9, and then, under the elastic force of the return spring 7, the protruding part of the puncture needle 6 will be pulled back into the finger cover body 1, so as to prevent the puncture needle 6 from hurting the birth canal of the puerpera, and the moving plate 5 The bottom is rotatably installed with a lead screw 8, a rotating hole 16 is opened on the bottom inner wall of the moving chamber 4, and a lead screw nut 17 is fixedly installed on the inner wall of the rotating hole 16. The bottom of the lead screw 8 penetrates the lead screw nut 17 and is connected with the lead screw. The nut 17 is threaded, and the screw nut 17 reduces the frictional force when the screw 8 moves. The bottom of the screw 8 penetrates the bottom inner wall of the moving chamber 4 and extends to the bottom of the fixed seat 3. The bottom of the screw 8 is rotated and installed with Pushing the plate 9, a protruding hole 13 is formed on the top inner wall of the finger sleeve groove 2, and the top of the puncture needle 6 extends into the protruding hole 13;

A positioning plate 10 is fixedly installed on both sides of the bottom of the push plate 9 , and two compression springs 11 arranged symmetrically are fixedly connected to one side of the two positioning plates 10 that are close to each other.
