Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a visual obstetric forceps, including two pincers leaves 1, two pincers leaves 1 all include nipper 2 and tong arm 3, two pincers leaves 1 are connected through articulated post 4 is articulated, fixed mounting has support column 5 on the articulated post 4, spiral shell section of thick bamboo 6 has been cup jointed on the support column 5, threaded connection has shift ring 7 on the spiral shell section of thick bamboo 6, shift ring 7's both sides are all rotated and are installed connecting rod 8, the other end of two connecting rod 8 rotates respectively and installs the inboard at two tong arm 3, section of thick bamboo 9 in the middle of the one end fixed mounting of spiral shell section of thick bamboo 6, be provided with pulling rod 10 in the middle of the section of thick bamboo 9, the one end fixed mounting that pulls rod 10 has pull ring 11, fixed mounting has first camera 12 on the articulated post 4, fixed mounting has.

The inner sides of the two nipper plates 2 are fixedly provided with cushion pads 14, the pulling rod 10 can drive the middle cylinder 9 to rotate, the middle cylinder 9 drives the screw cylinder 6 to rotate, thereby leading the movable ring 7 to approach the hinged column 4, leading the connecting rod 8 to drive the two forceps arms 3 to open by virtue of the connecting rod effect, so that the angle of the clamp plate 2 is increased to clamp the head of the fetus, and in the traction process, because the clamp arm 3 does not need to be manually operated to clamp, it is possible to ensure stable clamping force, and, during clamping, since the clamping effect of the nipper 2 can correspond to the moving distance of the moving ring 7, so that the clamping force of the clamp leaves 1 can be better controlled, the first camera 12 can observe the position of the fetal head, the condition that fetal head skin is compressed tightly can be observed through setting up camera two 13, makes things convenient for the doctor to control clearly of traction process, and the practicality is strong.

As shown in fig. 1 and 3, it is to be supplemented that a first limiting ring 15 is fixedly mounted on each of two sides of the screw barrel 6 on the support post 5, a second limiting ring 16 is fixedly mounted on each of two ends of the screw barrel 6, the first limiting ring 15 limits the position of the screw barrel 6 on the support post 5, and the second limiting ring 16 keeps the movement of the moving ring 7 on the screw barrel 6 within a certain range.

As shown in fig. 2, it should be added that a stepped groove 17 is formed at one end of the middle barrel 9, one end of the screw barrel 6, one end of the support column 5 and the first limit ring 15 on one side are all located in the stepped groove 17, one end of the screw barrel 6 is welded in the stepped groove 17, and thus the middle barrel 9 and the screw barrel 6 are fixedly connected, so that a doctor can conveniently control the screw barrel 6 at a longer distance.

As shown in fig. 2, in this embodiment, a blind hole 18 is formed at the other end of the middle cylinder 9, the pulling rod 10 is located in the blind hole 18, four centrosymmetric sliding slots 19 are formed at the blind hole 18 of the middle cylinder 9, four centrosymmetric protrusions 20 are arranged on the pulling rod 10, the four protrusions 20 are respectively located in the four sliding slots 19, and due to the cooperation between the protrusions 20 and the sliding slots 19, the pulling rod 10 can only extend and retract in the middle cylinder 9, and the middle cylinder 9 can rotate along with the rotation of the pulling rod 10.

As shown in fig. 4, in the present embodiment, the second camera 13 is located at the outer bottom of the vise plate 2, and the probe of the second camera 13 faces the inner side of the vise plate 2, so that the second camera 13 neither affects the clamping of the vise plate 2 on the fetal head, nor records the condition of the fetal head.

As shown in figure 1, what need to be supplemented is that camera one 12 and camera two 13 are wireless cameras to make things convenient for the utility model to stretch into the lying-in woman internally, carry out the centre gripping, avoid the pencil to influence the going on of pulling work, as shown in figure 1, it is worth explaining that, the material of blotter 14 adopts medical silicon rubber material, and medical silicon rubber material has guaranteed the health and safety of blotter 14, plays certain guard action simultaneously.

When the visual obstetric forceps of the embodiment is used, the forceps leaves 1 are extended into the body of a lying-in woman, then the forceps arms 3 are held by hands to slowly enable the forceps plates 2 to approach the head of the fetus by observing pictures transmitted by the cameras I12, the pull ring 11 is pulled out when the forceps plates are close to the head of the fetus, the pull ring 11 drives the pull rod 10 to be pulled out in the middle barrel 9, when the forceps are pulled out to a position convenient for a doctor to operate, the pull rod 10 is rotated to drive the middle barrel 9 to rotate, the middle barrel 9 drives the screw barrel 6 to rotate, the screw barrel 6 enables the movable ring 7 to move, thereby driving the connecting rod 8 to open the clamp arms 3, so as to open the clamp plates 2, when the clamp plates 2 are positioned at the two sides of the head of the fetus, and slowly and reversely rotating the pulling rod 10 by observing the picture transmitted by the second camera 13, so that the clamping plate 2 slowly clamps the head of the fetus, and after clamping, keeping the pulling rod 10 still and slowly pulling out the head of the fetus.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
