Description

Technical Field

[0001] The utility model relates to an obstetric forceps capable of avoiding injury. Background Art

[0002] Forceps are one of the important tools for vaginal delivery. If used correctly under appropriate circumstances, they can ensure the safety of mother and child, avoid conversion to cesarean section, and thus reduce complications of cesarean section. They are suitable for mothers with no pregnancy complications and comorbidities and a prolonged second stage of labor; those with fetal distress, such as turbid amniotic fluid, fetal heart rate changes, or abnormal electronic fetal heart rate monitoring, suspected fetal intrauterine hypoxia, and the need to end delivery in a short time; those who need to shorten the second stage of labor due to maternal factors such as pregnancy complications or complications, such as mothers with heart disease, or complications of gestational hypertension, scarred uterus, and vaginal trial of labor. When using forceps, doctors need to receive strict training and assessment before using them. In the hands of experienced midwives, they are very dexterous and convenient to use, and will cause little damage to mothers and newborns, so there is no need to worry or be afraid.

[0003] Forceps are tools used to smoothly pull out the fetal head. When the doctor is operating, the forceps need to clamp the baby's head and pull it out. Due to the clamping force of the forceps during operation, it is easy to cause harm to the baby and the mother, and it is not easy to operate the forceps effectively, which brings difficulties to the midwifery operation and reduces the safety of the use of forceps.

[0027] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0028] like Figure 1-4 As shown, the injury-avoiding obstetric forceps include: in this technical solution,

[0029] A connecting shaft 1, wherein a clamp 2 is rotatably connected inside the connecting shaft 1, a guide rod 10 is fixedly connected to the surface of the connecting shaft 1, a suction cup 11 is fixedly connected to one end of the guide rod 10, and a locking mechanism is provided at the other end of the guide rod 10;

[0030] The front end of the clamp 2 is sleeved with a protective cover 4, and the surface of the clamp 2 located on one side of the protective cover 4 is provided with a clamping mechanism for fixing the protective cover 4, and the rear end of the clamp 2 is connected to the locking mechanism through a connecting rod 13.

[0031] In the technical solution, two cross-distributed clamps 2 are provided inside the connecting shaft 1 , and the two clamps 2 are rotatably connected to each other in the middle and are symmetrically distributed on both sides of the connecting shaft 1 .

[0032] In the present technical solution, the number of the guide rods 10 is two, the two guide rods 10 are located between the clamps 2 and symmetrically distributed on both sides of the connecting shaft 1, and the two guide rods 10 are respectively connected to both sides of the suction cup 11.

[0033] In the present technical solution, a plurality of limit blocks 9 are provided on both sides of the connecting shaft 1 , each limit block 9 is a U-shaped structure and is sleeved with a guide rod 10 , and a long hole 12 is opened at one end of the guide rod 10 .

[0034] In the present technical solution, the locking mechanism includes a screw 14 , which passes through the two guide rods 10 and is slidably connected to the inside of the long hole 12 , and the end of the screw 14 is threadedly connected to the nut 15 , and the nut 15 contacts the surface of the guide rod 10 .

[0035] In the present technical solution, there are two connecting rods 13 , and the two connecting rods 13 are rotatably connected to the two clamps 2 respectively, and one end of each connecting rod 13 is rotatably connected to the middle of the screw rod 14 .

[0036] In the present technical solution, the clamping mechanism includes a clamp rod 6 , the middle portion of which is rotatably connected to the clamp 2 , one end of which is fixedly connected to a barb 7 , and the barb 7 is in contact with the surface of the protective cover 4 .

[0037] In the present technical solution, the number of the clamping rods 6 is four, and every two of the clamping rods 6 are symmetrically distributed on both sides of the front end of the clamp 2 .

[0038] In the present technical solution, an opening 5 is provided at the front end of the clamp 2 , a spring 8 is provided inside the opening 5 , and both ends of the spring 8 are fixedly connected to the clamp rod 6 .

[0039] In the present technical solution, a buffer bar 3 is embedded and connected to the front end of the clamp 2. There are two buffer bars 3. The two buffer bars 3 are respectively located on adjacent sides of the two clamps 2, and the buffer bars 3 are located inside the protective cover 4.

[0040] When the present application is in use, the clamp rod 6 is pressed to rotate around its middle and drive the barb 7 to separate from the clamp 2, and then the protective cover 4 is put on the front end of the clamp 2. After the clamp rod 6 is released, the compressed spring 8 is reset inside the opening 5 and drives the clamp rod 6 to rotate, so that it drives the barb 7 to clamp the protective cover 4 to fix the protective cover 4. By rotating the rear end of the clamp 2, it drives its front end to rotate to clamp the baby's head. When the clamp 2 rotates, the connecting rod 13 pushes the screw rod 14 and slides inside the long hole 12 without affecting the normal rotation of the clamp 2. When the clamp is clamped, the guide rod 10 is pushed so that the guide rod 10 is The limiting block 9 moves stably inside and drives the suction cup 11 to adsorb and fix the baby's head.

The adsorption force of the suction cup 11 can appropriately reduce the clamping force of the clamp 2 to avoid causing damage to the baby. At the same time, the buffer strip 3 and the protective cover 4 on the clamp 2 can contact the baby's head to play a buffering and protective role, thereby improving the safety performance. After use, the protective cover 4 is removed for subsequent use.
