Description

Placenta clamping forceps

Technical Field

The utility model relates to a medical apparatus technology, in particular to a device technology of placenta clamping forceps.

Background

In the process of obstetrical delivery, when the placenta is adhered to or implanted in the inner wall of the uterus and cannot be naturally delivered, a midwife needs to operate to take out the placenta from the forceps clamps in the uterus so as to prevent postpartum hemorrhage. The device for clamping and taking out the placenta is an oval forceps which is an X-shaped structure (similar to a scissors structure) consisting of two forceps rods which are pivoted with each other, and an operator needs to control the opening and closing degree of the two forceps rods by hand to control a forceps head to clamp placenta tissues and then take out the placenta tissues. The forceps heads of the oval forceps are flat and small in size, a small number of tissues can be clamped by single operation, the placenta can be completely taken out only by repeatedly passing in and out of the uterine cavity, the operation is inconvenient, and the flat forceps heads are easy to cause cervical tissue damage when passing in and out of the uterine cavity, so that much bleeding and infection are easy to occur; and the two clamp rods are in an X shape after being opened, so that the occupied space is large, and the operation is not flexible. In addition, the length of the oval forceps is fixed, the length cannot be adjusted according to the depth of the uterine cavity, and the oval forceps with various lengths need to be configured to meet different puerpera.

SUMMERY OF THE UTILITY MODEL

To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a convenient operation, flexibility are provided to the pincers are got to placenta clamp that can effectively avoid haring cervical tissue.

In order to solve the technical problem, the utility model provides a pincers are got to placenta clamp, its characterized in that: comprises a clamp barrel and a clamp rod;

a handle is fixed at the left end of the forceps rod, a return spring is sleeved at the left part of the forceps rod, a rod body of the forceps rod is inserted into a barrel cavity of the forceps barrel in a sliding fit manner, the left end of the return spring is tightly propped against the handle, and the right end of the return spring is tightly propped against the left end of the forceps barrel;

the right end of the clamp rod is provided with two elastic clamp arms, the left ends of the two clamp arms are fixedly connected with the clamp rod, the right ends of the two clamp arms are respectively fixed with a hemispherical clamp head, the two clamp heads respectively tightly abut against the right end of the clamp barrel, the two clamp heads are oppositely folded into a hollow sphere, and the adjacent side edges of the two clamp heads are in a sawtooth shape;

and after the two forceps heads slide rightwards along with the forceps rod to be separated from the right end of the forceps barrel, the two forceps heads can be separated back to back under the driving of the elastic force of the two forceps arms.

Furthermore, the clamp rod consists of a left rod section and a right rod section, and the left rod section and the right rod section are connected with each other in a thread fit mode.

The placenta clamping forceps provided by the utility model can control the opening and closing of the two forceps heads only by operating the forceps rod to slide left and right, and the forceps heads folded into a sphere can avoid injuring human tissues when coming in and going out of the cervical orifice, the tissues clamped by the forceps head group with the spherical structure through single operation can be more than the flat forceps head group, the times of operation in and out of the uterine cavity can be reduced, the operation is very convenient, the placenta can be stably clamped under the assistance of the elasticity of the return spring, only two forceps heads are opened when the placenta is clamped, the occupied space in the uterine cavity is small, and the placenta clamping forceps has the characteristic of flexible operation; and the length of the forceps rod can be adjusted according to the depth of the uterine cavity, so that the operation flexibility can be further increased.

Drawings

fig. 2 is a schematic diagram of the placenta clamping forceps according to the embodiment of the present invention, in which two forceps heads are opened.

Detailed Description

The following description will be made in detail with reference to the accompanying drawings, but the present embodiment is not intended to limit the present invention, and all similar structures and similar variations thereof adopted by the present invention should be included in the protection scope of the present invention, and the relations between the numbers of the components in the present invention are shown.

As shown in fig. 1-2, the placenta clamping forceps provided by the embodiment of the present invention is characterized in that: comprises a clamp barrel 1 and a clamp rod;

the clamp rod consists of a left rod section 2 and a right rod section 3, and the left rod section 2 and the right rod section 3 are connected with each other in a thread matching mode; a handle 4 is fixed at the left end of the forceps rod, a return spring 5 is sleeved at the left part of the forceps rod, the rod body of the forceps rod is inserted into the barrel cavity of the forceps barrel 1 in a sliding fit manner, the left end of the return spring 5 tightly abuts against the handle 4, and the right end of the return spring 5 tightly abuts against the left end of the forceps barrel 1;

the right end of the clamp rod is provided with two elastic clamp arms 6, the left ends of the two clamp arms 6 are fixedly connected with the clamp rod, the right ends of the two clamp arms 6 are respectively fixed with a hemispherical clamp head 7, the two clamp heads 7 are respectively tightly propped against the right end of the clamp barrel, the two clamp heads 7 are oppositely folded into a hollow sphere shape, and the adjacent side edges of the two clamp heads 7 are in a sawtooth shape;

and after the two binding clip 7 slide rightwards along with the binding clip until the two binding clip is separated from the right end of the binding clip 1, the two binding clip 7 can be separated back to back under the driving of the elasticity of the two binding clip arms 6.

The embodiment of the utility model provides a press from both sides and get placenta clinically for obstetrical department, its using-way as follows:

two forceps heads 7 folded into a hollow sphere shape extend into a target position of a uterine cavity from a cervical orifice of a puerpera, then the handle 4 is pushed by hand, two forceps arms 6 gradually extend out of the forceps barrel, the two forceps heads 7 are separated from the forceps barrel 1, and the splayed forceps heads are driven to open by the elasticity of the two forceps arms 6;

then, the two forceps heads 7 are aligned to the placenta to enable the placenta to be located between the two forceps heads 7, then the force applied to the handle 4 is released, the forceps rods can gradually return under the elastic force of the return springs 5, the two forceps arms 6 gradually retract into the forceps barrel, after the two forceps arms 6 touch the forceps barrel, the two forceps arms 6 generate elastic deformation under the blocking of the forceps barrel, the two forceps heads 7 are gradually folded oppositely, the placenta is clamped, after the clamping is stable, the forceps barrel and the forceps heads are pulled out of the body, and the placenta can be successfully taken out.

Because left pole section 2 and right pole section 3 are screw-thread fit, rotate the right pole section 3 of tong pole left pole section 2 relatively, can adjust the length of tong pole to can be according to the depth of uterine cavity, adjust the length of tong pole.
