Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, in particular to a novel obstetric forceps. Background Art

[0002] The forceps are divided into two leaves, and a space of similar size and shape to the fetal head is formed between the two leaves. The fetal head is embraced and protected to prevent it from being squeezed. The midwife holds the handle of the forceps and gently pulls it outward to help deliver the fetal head.

[0003] The functions of the commonly used forceps are relatively simple. First of all, the length of the handles of the forceps is generally fixed and cannot be adjusted, which will undoubtedly reduce the application range of the forceps. At the same time, after the fetus's head is clamped by the forceps, the staff still needs to pull the forceps outward. During this process, the opening and closing state of the forceps cannot be fixed. During the pulling process, if the force is unevenly applied, the forceps will further shrink, thereby affecting the fetus's head.

[0004] Therefore, it is necessary to provide a new novel obstetric forceps to solve the above-mentioned problems. Utility Model Content

[0028] The working principle of the novel obstetric forceps provided by the utility model is as follows:

[0029] When the obstetric forceps are in use, the staff member passes the fingers through the finger rings on the two extension arms 1 to control the opening and closing degree of the forceps body 3, and the protective pad 4 on the forceps body 3 can effectively protect the fetus' head.

[0030] In special circumstances, when it is necessary to extend the length of the extension arm 1, the staff can rotate the two knobs respectively. The rotation of the two knobs will drive the two threaded tubes 9 to rotate respectively, thereby shortening the two extension rods 10, and then separating the two contact heads 11 from the two clamping blocks 8 respectively. In this way, the staff can hold the clamp body 3 with one hand and pull the two extension arms 1 with the other hand. When the two extension arms 1 are subjected to force, the two clamping blocks 8 will respectively contact the tooth plates 6 in the two strip grooves 5, and the clamping blocks 8 will retract into the two clamping chambers 7 after being subjected to force, and when the clamping blocks 8 are separated from the top teeth of the tooth plates 6, the spring 12 will push the clamping blocks 8 again to a state of engagement with the top teeth, thereby completing the lengthening operation of the extension arm 1.

[0031] After the extension arm 1 is extended to a certain length, the staff can then turn the knob in the opposite direction to extend the two extension rods 10, and finally make the contact head 11 contact with the two clamping blocks 8. At this time, the two clamping blocks 8 will not be able to be forced to retract into the clamping bin 7, thereby achieving the positioning effect of the clamping blocks 8.

[0032] When adjusting the pliers body 3 to open, the staff needs to pull out the positioning rod 21. In this way, when the pliers body 3 is opened, the two extension arms 1 move away from each other, so that the two hinged plates 15 gradually rotate to a horizontal state. At the same time, the rotation of the two hinged plates 15 will drive the two rotating shafts 17 and the two gears 18 to rotate, and finally drive the tooth plate 19 to move horizontally. After the pliers body 3 is opened to a suitable angle, the positioning rod 21 can be inserted again to limit the tooth plate 19, so that the two hinged plates 15 will not rotate, thereby achieving the effect of fixing the opening and closing angle of the pliers body 3.

[0033] Compared with the related art, the new obstetric forceps provided by the utility model has the following beneficial effects:

[0034] The utility model provides a novel obstetric forceps. The length of the device can be increased by adjusting two extension arms 1, so that it can cope with the use of different personnel and different working environments. Further, after the forceps body 3 is adjusted to a suitable angle, the opening and closing angle of the forceps body 3 can be fixed by inserting a positioning rod 21, so that the head of the fetus can be effectively protected from excessive squeezing during use by the staff.
