Abstract
The utility model relates to a medical appliance, in particular to a surgical self-through drainage tube, which is characterized in that a puncture needle comprises two parts: a puncture head part and a combination part combining with a drainage tube which is sleeved on the combination part of the puncture needle, wherein, the outer diameter of the combination part matches with the inner diameter of the drainage tube, and the outer diameter of the puncture head part matches with that of the drainage tube. The utility model has the following advantages that a doctor can puncture through skin and control the direction of the puncture easily. Because the drainage tube combines firmly with the puncture needle that the doctor can achieve an exact position of the drainage tube by controlling the puncture needle. As the diameter of the combination part of the puncture needle with the drainage tube is similar to that of the drainage tube, a wound size cannot be increased. A drainage tube with appropriate size and shape is chosen according to an operation position. Owing to the advantages, the time and the risk of an operation can be reduced.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of formula of wearing certainly drainage tube that is used for surgery.
Background technology:
At present, the surgical drainage tube kind of Ying Yonging is a lot of clinically, what have is used for urethral catheterization, what have is used for wound, on thoracic cavity, encephalocoele, gastrointestinal tract and the biliary tract, and the surgical drainage purpose be with between tissue or the pus that gathers in the body cavity, blood, liquid-conducting to external, prevent postoperative infection and influence wound healing.Therefore in the middle of clinical operation, the doctor is before closing wound, need to install drainage tube, for present drainage tube, the doctor need use the installation of the auxiliary drainage tube of instruments such as scalpel and mosquito forceps, usually adopt earlier with scalpel standardized osculum on skin, pass osculum with mosquito forceps, the clamping drainage tube, make drainage tube can pass skin, reach the drain purpose, but the operation drainage tube is neither simple and convenient like this, the wayward direction of expend energy on causes operation risk easily during simultaneously with the mosquito forceps transdermal.
The utility model content:
The purpose that this utility model will be realized provides the formula of wearing the certainly drainage tube that a kind of doctor is easy to transdermal and can controls power thrusts.
This utility model for realizing the technical scheme that purpose adopted is: wear the formula drainage tube certainly and comprise drainage tube and thread a needle thorn, the thorn that it is characterized in that threading a needle is divided into puncture head and drainage tube joint portion, drainage tube is enclosed within the drainage tube joint portion of the thorn of threading a needle and the external diameter of the thorn drainage tube joint portion of threading a needle and drainage tube interior through matching, and puncture head outer diameter and the drainage tube external diameter that stings of threading a needle matches.
Described drainage tube is common nonmetal drainage tube, and its wall Guan Shangke has conduction hole or do not open conduction hole.
The puncture head of described puncture needle is a prong structure, has direct puncture function.
The puncture head of described puncture needle is ascending to drainage tube joint portion size, and is a tangible bending radian.
Described puncture needle can be a bulk metal and constitutes, and also can be two or more parts and constitutes.
The beneficial effect that this utility model produced is: by wearing the puncture needle of formula drainage tube certainly, the doctor is easy to transdermal and can controls power thrusts, because drainage tube and puncture needle firmly combine, so the doctor just can obtain the installation site accurately of drainage tube by the control puncture needle; Because the diameter of puncture needle and drainage tube joint portion and the diameter of drainage tube itself are basic identical, so when increasing the wound size, can select the drainage tube of suitable dimension and shape according to operative site; Because this puncture characteristic, the doctor can save operating time, reduces operation risk.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
1, drainage tube 2, the thorn 3 of threading a needle, puncture head 4, drainage tube joint portion
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is described further:
In Fig. 1, comprise drainage tube 1 and the thorn 2 of threading a needle from the structure of wearing the formula drainage tube, the thorn 2 of threading a needle is made up of puncture head 3 and drainage tube joint portion 4, the internal diameter of drainage tube 1 just in time matches with drainage tube joint portion 4 external diameters of puncture needle 2, drainage tube 1 just in time is enclosed within on the drainage tube joint portion 4, the external diameter of drainage tube 1 just in time matches with thorn 2 puncture head 3 external diameters of threading a needle, and forms a plane.
Wherein said drainage tube 1 is made for common metal, has conduction hole or does not open conduction hole at its wall Guan Shangke.
The puncture head 3 of wherein said puncture needle 2 is a prong structure, and ascending to the size of drainage tube joint portion 4, its profile is certain bending radian, also can be two or more parts.
Claims (5)
