Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Please refer to fig. 1, the utility model provides an obstetric forceps for obstetrical surgery, including

horizontal pole

1, 1 mid point bilateral symmetry of horizontal pole articulates there are two pincers handles 4, two the lower extreme of pincers handle 4 passes through spring 5 to be connected, the upper end all articulates there is connecting rod 12, sliding tray 2 has all been seted up to the back of the body one side of the back of the body of horizontal pole 1 with pincers handle 4 pin joint, sliding tray 2 sets up along the length direction of horizontal pole 1, equal sliding connection has tong arm 3 in sliding tray 2, the upper end of tong arm 3 sets up to the curved form that adapts to neonate's head, the tip of connecting rod 12 is articulated with the middle part of tong arm 3, the 1 outside of horizontal pole is provided with external screw thread 10, the equal threaded connection in both ends of horizontal pole 1 has location sleeve 14, location sleeve 14 is located the 3 lower extreme outsides of tong arm and can restrict tong. The above constitutes the basic structure of the present invention.

In order to further improve the security, as preferred, the utility model discloses in, please refer to and draw figure 2, 1 center department of horizontal pole sets up porosely 11, sliding connection has montant 6 in the hole 11, montant 6's upper end is connected with sucking disc 8, the lower extreme is connected with tractive handle 7, during the use, except holding the outside tractive of pincers handle 4 with holding, uses the fixed neonate's of sucking disc 8 head, grips tractive handle 7 outside application of force simultaneously, neonate's head three point atress, and is little to neonate's damage.

In order to prevent the front end of the forceps arm 3 from impressing an indentation under the jaw of a newborn, preferably, the utility model discloses in, the inner side of the upper end of the forceps arm 3 is provided with a silica gel cushion 13.

In order to facilitate the use of the midwife, preferably, the utility model discloses in, the lower extreme of pincers handle 4 is provided with the friction bump 9 that is convenient for to grip.

The working principle is as follows: when the adjustable clamp is used, the positioning sleeve 14 is adjusted to move towards the two ends of the cross rod 1, at the moment, the spring 5 contracts inwards to drive the lower end of the clamp handle 4 to rotate inwards, the upper end of the clamp handle 4 drives the connecting rod 12 to rotate outwards, the connecting rod 12 drives the clamp arm 3 to move towards the two ends of the cross rod 1 along the sliding groove 2, the clamp arm 3 moves to the two ends of the cross rod 1 along with the positioning sleeve 4, and the opening of the clamp arm 3 is in the maximum state at the moment; then the front end of the forceps arm 3 is placed at the lower jaw of the newborn, the two positioning sleeves 14 are adjusted to move towards each other, the positioning sleeves 14 push the two forceps arms 3 to move towards each other, when the front end of the forceps arm 3 moves to be matched with the lower jaw of the newborn, the positioning sleeves 14 stop rotating, at the moment, the spring 5 is in a stretching state, the upper end of the forceps handle 4 tends to move outwards, and therefore the lower end of the forceps arm 3 is tightly abutted against the side face of the positioning sleeve 14 and cannot move. The head of the child is enclosed and fixed; then, the midwife holds the lower end of the forceps handle 4, applies force outwards to draw, and assists the parturient in producing.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention and are not intended to limit the spirit and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by the technical solution of the present invention by those skilled in the art should fall into the protection scope of the present invention, and the technical contents claimed by the present invention have been fully recorded in the claims.
