Description

Trocar for placing deep soft tissue drainage

Technical Field

The utility model relates to the technical field of medical devices, in particular to a trocar for placing deep soft tissue drainage.

Background

Surgical drainage is to guide pus, blood and other liquid accumulated in human tissue or body cavity to outside the body to prevent postoperative infection and wound healing.

The drainage device that current well is commonly used is the drainage needle, like patent document is CN209204240U, a postoperative soft tissue hydrops drainage device, and this postoperative soft tissue hydrops drainage device includes: one end of the drainage tube is a drainage end, and a plurality of drainage side holes are formed in the tube wall of the drainage end; and a puncture guide wire piece, which is provided with a needle part, a connecting part fixedly connected with the needle part and a guide wire part fixedly connected with one end of the connecting part, which is far away from the needle part, wherein the connecting part is cylindrical and has a diameter matched with the inner diameter of the drainage tube, the inner wall of the drainage tube is provided with internal threads, the side surface of the connecting part is provided with external threads matched with the internal threads, the tube wall of the drainage tube is sleeved on the side surface of the connecting part and is in threaded connection with the connecting part, the needle part extends out from the drainage tube, one end of the guide wire part, which is far away from the connecting part, extends out from one end of the drainage tube, which is far away from the needle part, and after the drainage tube penetrates soft tissues under the guidance of the needle part, the guide wire part can drive the connecting part to rotate along the internal threads to exit the inner wall of the drainage tube.

In the drainage device, the operation is not easy in actual use, and the drainage effect is not good, so that the drainage device is not suitable for carrying out penetrating drainage for a plurality of times.

Improvements in this regard are needed.

Disclosure of Invention

The utility model aims at solving the technical problems in the prior art and provides a trocar for placing deep soft tissue drainage, which mainly aims at solving the problems in the background art by designing a novel-structure drainage device to insert a drainage strip in a puncture mode.

In order to solve the technical problems, the utility model adopts the following technical scheme: a trocar for placement of deep soft tissue drainage, comprising: the outer tube is of a hollow cylindrical structure; the inner tube is arranged in the outer tube, the inner tube can slide relative to the outer tube, and through holes for the drainage strips to pass through are formed in two sides of the end part of the inner tube.

Further, the drainage strip is gauze.

Further, the outer tube and the inner tube are made of transparent materials.

Further, the end of the inner tube gradually contracts along the central axis.

Compared with the prior art, the utility model has the beneficial effects that: through the novel structure designed, during the use, penetrate inside and outside pipe, pass the through-hole on the inner tube with the drainage strip, and then take out inside and outside pipe, keep somewhere the drainage strip on the human body, with liquid guide such as pus, blood to external, have convenient operation and the effectual advantage of drainage.

Reference numerals: 1. an outer tube; 2. an inner tube; 3. a drainage strip; 4. and a through hole.

Detailed Description

The utility model is described in further detail below with reference to the accompanying drawings.

The embodiments described by referring to the drawings are exemplary and intended for purposes of illustrating the present application and are not to be construed as limiting the present application. In the description of the present application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," etc. indicate or are based on the orientation or positional relationship shown in the drawings, merely for convenience of description and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present application, the meaning of "a number", "a plurality" or "a plurality" is two or more, unless explicitly defined otherwise. In the present application, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this application will be understood by those of ordinary skill in the art as the case may be. In this application, unless expressly stated or limited otherwise, a first feature "above" or "below" a second feature may include both the first and second features being in direct contact, and may also include the first and second features not being in direct contact but being in contact with each other by way of additional features therebetween. Moreover, a first feature being "above," "over" and "on" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is higher in level than the second feature. The first feature being "under", "below" and "beneath" the second feature includes the first feature being directly above and obliquely above the second feature, or simply indicating that the first feature is less level than the second feature.

In view of the technical problems noted in the background, as shown in fig. 1-2, there is provided a trocar for placing deep soft tissue drainage, comprising: an outer tube 1, wherein the outer tube 1 is of a hollow cylindrical structure; the inner tube 2 is arranged in the outer tube 1, the inner tube 2 can slide relative to the outer tube 1, and through holes 4 for the drainage strips 3 to pass through are arranged on two sides of the end part of the inner tube 2.

The end of the outer tube 1 is an opening, the end of the inner tube 2 with the through hole 4 extends to the outer side of the outer tube 1, and the inner tube 2 is of a solid structure. In use, for example, the deep soft tissue position of the foot needs to be drained, when in use, the outer tube 1 and the inner tube 2 penetrate through the foot position, the drainage strip 3 penetrates through the through hole 4 arranged on the inner tube 2, and then the inner tube 2 is pulled to pull the drainage strip 3 to the other side of the foot, and then the outer tube 1 is taken out, so that the whole operation process is completed.

Through the drainage structure that sets up above, it has convenient operation's advantage, can carry out puncture drainage many times fast, simultaneously, the drainage strip 3 of keeping somewhere adopts the mode of both ends drainage, and the drainage effect is better, can reduce puncture quantity, alleviates patient's damage.

As a preferred embodiment, the drainage strip 3 is gauze, and drainage effect is improved by drainage at two ends of the gauze.

As a preferred embodiment, the outer tube 1 and the inner tube 2 are made of transparent materials. The transparent material is adopted for preparation, so that the operator can observe conveniently.

As a preferred embodiment, the end of the inner tube 2 is tapered along the central axis. The end part of the inner tube 2 is prepared into a tip shape, so that the puncture work is convenient.

The above description should not be taken as limiting the scope of the utility model, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical principles of the present utility model still fall within the scope of the technical solutions of the present utility model.
