As shown in fig. 1-3, a puncture separating forceps for a chest tube comprises a first forceps arm 1 and a second forceps arm 2 which are hinged with each other, wherein the hinged position is located in the middle of the first forceps arm 1 and the second forceps arm 2; the front ends of the first forceps arm 1 and the second forceps arm 2 are both provided with a puncture section 7, and the front end of the puncture section 7 is sharp and can penetrate through the thoracic cavity; the axis of the puncture section 7 is perpendicular to the first forceps arm 1 and the second forceps arm 2, so that the puncture section 7 can be punctured and can be operated by medical personnel conveniently, namely when the medical personnel puncture the thoracic cavity by using the device, the puncture section 7 can be pressed by the first forceps arm 1 and the second forceps arm 2; the two sections of the puncture sections 7 are combined into a cone shape, so that the puncture sections 7 can be conveniently penetrated, and the muscular tissues can be expanded into approximately circular puncture holes when the muscular tissues are expanded, and the catheter can be conveniently placed.

In this embodiment, a clamping plate 4 is fixed at the tail end of the first clamp arm 1, a plurality of clamping teeth 41 are uniformly arranged on the end surface of the clamping plate 4, the clamping teeth 41 face the tail end of the first clamp arm 1, a clamping block 3 is connected to the tail end of the second clamp arm 2 in a sliding manner, and the geometric dimension of the front end of the clamping block 3 is matched with the gap between the clamping teeth 41 and the clamping teeth 41; specifically, when the angle between the first forceps arm 1 and the second forceps arm 2 needs to be locked, the fixture block 3 is slid, so that the fixture block 3 is clamped into the gap between the clamp tooth 41 and the clamp tooth 41, and the purpose of locking is achieved, at the moment, the force of the muscle tissue for enabling the first forceps arm 1 and the second forceps arm 2 to approach is approximately perpendicular to the sliding direction of the fixture block 3, and the state of the fixture block 3 cannot be changed; when the first clamp arm 1 and the second clamp arm 2 need to be unlocked, only the fixture block 3 needs to be shifted, so that the fixture block 3 exits from a gap between the fixture tooth 41 and the fixture tooth 41, and the unlocking is completed.

In the embodiment, in order to facilitate the operation of the medical staff, a force is applied to separate the first forceps arm 1 and the second forceps arm 2, the finger rings 5 are disposed at the tail ends of the first forceps arm 1 and the second forceps arm 2, and the fingers of the medical staff can pass through the finger rings 5.

In this embodiment, since the first clamping arm 1 and the second clamping arm 2 rotate with the hinged position as the center of circle, in order to enable the fixture block 3 to be connected with the fixture plate 4 all the time by passing through the center of circle of the fixture plate 4, it is ensured that the force applied by the muscle tissue to the first clamping arm 1 and the second clamping arm 2 to be drawn together acts on the fixture block 3 through the fixture plate 4, so that the stress of the fixture block 3 is perpendicular to the sliding direction and the end surface of the latch 41, the shape of the fixture plate 4 is an arc shape with the hinged position as the center of circle, the fixture plate 4 spans the first clamping arm 1 and the second clamping arm 2, and the sliding direction of the fixture block 3 is along the length direction of the second clamping arm 2.

In this embodiment, the clamping plate 4 is fixed between the hinged position and the tail end of the first forceps arm 1, and the clamping block 3 slides between the hinged position and the tail end of the second forceps arm 2 to be close to the finger ring 5, so that the medical staff can operate the clamping plate with one hand conveniently.

In the present embodiment, specifically, in order to enable the fixture block 3 to slide with the second caliper arm 2, a sliding groove is provided on the second caliper arm 2, and the fixture block 3 is connected with the sliding groove in a sliding manner.

In this embodiment, the puncture section 7 is provided with a scale 6, which can preliminarily determine the thickness of the chest wall, thereby estimating the length of the implantation tube.

In this embodiment, a puncturing and separating forceps for a chest tube works as follows:

a medical worker penetrates a finger ring 5, applies force to the first forceps arm 1 and the second forceps arm 2, the force enables the puncture section 7 to penetrate through the thoracic cavity, the medical worker judges the depth of penetrating through the thoracic cavity according to the scale 6, after the depth reaches a specified depth, the medical worker applies force to enable the first forceps arm 1 and the second forceps arm 2 to be separated, until the first forceps arm 1 and the second forceps arm 2 are separated to a specified angle, the puncture section 7 props open muscular tissues, the fixture block 3 is pushed, the fixture block 3 is clamped into a gap between the clamping tooth 41 and the clamping tooth 41, and therefore the first forceps arm 1 and the second forceps arm 2 are locked; subsequently, the medical staff can insert the drainage tube at the position where the puncture section 7 separates the muscular tissue, and the tube placing operation is completed.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
