Abstract

The utility model discloses a contraceptive device removing clamp to solve problems in prior ring-removing device of difficult removing and causing injury to patients. The utility model comprises a nip head clamp groove, a nip front arm, a joint, a rear handle, a fixing card and a clamp holding hole. The nip front arm has a bending radian of 0.2-0.3 and a length of 65-70 millimeter. The utility model is characterized in that (1) the nip front arm 2 is matching with the uterine angle and the length is close to the normal depth of the uterine cavity, and the uterine cervix width is not increased when the clamp is opened. (2) The lateral bending of the nip front arm makes clamping easy and increases accuracy of device removing. (3) The diameter of the round hole at the nip head is slightly smaller than the cross section diameter of various contraceptive device arms, which enables the clamp to clamp the IUD body well without sliding off, to essentially fit the clamp tip part and to reduce the position occupied by clamp ring and resistance when taking out IUD. (4) The front arm at one side of the nip is provided with scale to know the depth entering the uterine cavity ,which decreases difficulty in removing device and reduces operation injury to patients.

Description

The birth control apparatus forceps

Technical field this utility model relates to a kind of device for taking out of intrauterine contraceptive device (IUD) tool that is used for obstetrics and gynecology department, a kind of specifically birth control apparatus forceps.

Background technology intrauterine device IUD arises from the sixties at clinical application, and in reaching between the operating period in 40 years, getting the device hook is the instrument that the unique IUD of being used for of basic unit takes out.The device hooking device is got in use, IUD must can carry pulling force can be effective, so the taking-up to closo IUD such as round, circle palace type, palace types is effective, and to opening IUD, as moving disappearance in the IUD tailfibers such as T type, parent pleasure, Ji Ni, no tailfiber fancy ring and closo IUD take off knot, fracture, residual taking-up and but are difficult to play a role.Constant factor palace curvature is excessive in operating process simultaneously, or hooks up repeatedly, and bail easily causes damage to the palace wall.

Existing IUD forceps, though overcome the single device mode of getting, its jaw forearm is shorter, radian is bigger than normal, when getting device and uterine cavity incompatible; Jaw head is held level with both hands, and the shared position of pincers rings and to take out resistance bigger during the clamp birth control apparatus is to having relatively high expectations of cervix uteri; Jaw forearm frontal arc, when with the uterus bend degree one to the time, about drive pincers, the clamp scope is bigger, and certain blindness is arranged.

Utility model content the purpose of this utility model provides a kind of birth control apparatus forceps, to solve the problem that existing device for taking out of intrauterine contraceptive device (IUD) takes out difficulty, causes operation receiveing person's wound.

This utility model comprises jaw head end draw-in groove, jaw forearm, joint, back handle, fixing card, clamp-holding hole; The crooked radian of described jaw forearm is 0.2～0.3, and the length of jaw forearm is 65～70 millimeters.

This utility model characteristics are that 1. jaw forearm 2 adapts with the uterus angle, and the normal depth of length and uterine cavity is close, and the joint is positioned at cervix uteri mouth place when getting device, do not increase the uteri position width when opening pincers; During the birth control apparatus of clamp diverse location, get inside and outside the moving of device pincers, uteri position wide variety not obvious (0.5-1 millimeter) in 10 millimeter.2. jaw forearm lateral bending is driven pincers with fore-and-aft direction behind the chamber of being put in prison, and two jaw forearms are close to the uterine cavity front and rear wall and are entered, and will place at the birth control apparatus of uterine cavity between two tong arms, and clamp has improved the accuracy of getting device easily.3. jaw head end Circularhole diameter (1.6-1.8 millimeter) is slightly less than each arm cross-sectional diameter of dissimilar birth control apparatus (2.0-2.1 millimeter), when getting device, can well block the IUD main body and be difficult for slippage, and can tip clamp part is involutory substantially, (jaw head end width is the 4-4.5 millimeter during clamp birth control apparatus, alleviates the resistance in the IUD taking-up process to reduce the shared position of pincers ring; 4. on the side jaw forearm scale is arranged, can understand the degree of depth that enters uterine cavity; 5. compare with Hook for removal of intrauterine device, the jaw head end is smooth, and it is accurate to get device, does not damage the palace wall.This utility model has reduced gets the device difficulty, has reduced the wound of operation to the operation receiveing person.

Below in conjunction with accompanying drawing this utility model is described in further detail.

Fig. 3 is the vertical view of this utility model tong arm.

Specific embodiment this utility model comprises jaw head end draw-in groove 1, jaw forearm 2, joint 3, back handle 4, fixing card 5, clamp-holding hole 6; The crooked radian of jaw forearm 2 is 0.2～0.3, and the length of jaw forearm 2 is 65～70 millimeters; Be carved with scale 7 on the one-sided jaw forearm 2, can understand the degree of depth that enters uterine cavity; The radius of jaw head end draw-in groove 1 is 0.8～0.9 millimeter, and the draw-in groove of two arm jaw head ends is symmetrically circular hole, and the cross section of one-sided back handle 4 is 2.6 * 2.6～3 * 3 millimeters; The width of fixing card 5 is 4～4.2 millimeters.

This utility model medical stainless steel material manufacture is reused after sterilizing.
