Abstract

The utility model relates to a puncture and fistulization drainage system, which belongs to a medical instrument. The utility model is mainly used for puncture and fistulization for bladders and thoracic drainage. The utility model comprises a handle; the utility model has the essential structure that the handle is provided with batteries, a display lamp, a polar plate and a spring; a puncture needle is fixed in the seat of the spring through a shoulder, the tail end of the puncture needle is contacted with the polar plate, and an inserting catheter is sheathed on the rear part of a cutting knife on the front end of the puncture needle. The utility model has the advantages of convenient operation, practicality, simple structure, etc.

Description

The puncture fistula-building drainage device

This utility model is to belong to medical apparatus and instruments, mainly as punctio vesicae fistulation and chest drainage.

The punctio vesicae fistulation is one of clinical operation commonly used, and the main apparatus of use is the trocar.During operation, need to carry out skin incision with scalpel earlier, then the trocar is inserted into intravesical by skin incision, when the feel trocar has when sense of falling through, needle section promptly is described in bladder cavity, this just needs the operator to have certain practical experience, in addition, nook closing member in extracting the trocar, the moment of inserting catheter again has urine gushes out, and besmirches medicated clothing, berth etc.; During chest drainage, after cutting skin, thrust straightly into the thoracic cavity and enlarge its passage with mosquito forceps, clamp drainage tube with mosquito forceps then and insert the thoracic cavity, equally also need the operator that certain practical experience is arranged, also have thoracic cavity blood or gas and overflow, make troubles to operator and patient along passage.

The purpose of this utility model is exactly at the problems referred to above, and puncture fistula-building drainage equipment a kind of easy and simple to handle, practical, simple in structure is provided.

The purpose of this utility model is achieved in that this utility model comprises handle, its structural feature is to have battery, display lamp, pole plate, spring in the handle, puncture needle is fixed in the spring base by convex shoulder, the tail end plates of similar polarity of puncture needle contacts, and the rear portion of the cutting knife of the front end of puncture needle is with inserts conduit.

Major advantage of the present utility model:

1. easy and simple to handle, practical:

When using this device to undergo surgery, cutting knife reaches in the cavity puncture needle rapidly by skin, display lamp is bright in this process, tight in the moment of extracting puncture needle to inserting vessel clamp, and then urine or blood, gas guided out, have do not leak outside, not dirty medicated clothing, easy and simple to handle, practical, and insert conduit and closely contact, not oozing of blood, no leakage with the hole of threading a needle.

2. simple in structure:

This utility model mainly is spring, pole plate, puncture needle, insert conduit forms, and assembly is few, body is simple, and its processing technology is simple.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of puncture needle;

Fig. 3 is the vertical view of Fig. 2;

Fig. 4 is the structural representation of inserting conduit;

Fig. 5 inserts the state diagram of conduit when placing on the puncture needle.

Below in conjunction with accompanying drawing concrete structure of the present utility model is described further:

This utility model comprises handle 9, have battery 7, display lamp 12, pole plate 8, pole plate 11, spring 6 in the handle 9, puncture needle 2 is fixed in the spring base 10 by convex shoulder 5, and the tail end plates of similar polarity 11 of puncture needle 2 contacts, and the rear portion of the cutting knife 1 of the front end of puncture needle 2 is with inserts conduit 3.

The convex shoulder 5 of puncture needle 2 has two, is to be symmetrical arranged; Has cannelure 4 in the spring base 10 corresponding to convex shoulder 5.

Has through hole 13 on the handle 9 corresponding to display lamp 12.

The cutting knife 1 of puncture needle 2 has four blades 14.

The front end of inserting conduit 3 is mushroom 15.

When using this device, at first pass through convex shoulder 5 with in the puncture needle 2 stator spring bases 10, when puncture needle 2 during with its cutting knife 1 incision skin, the counteracting force of skin causes pole plate 11 and pole plate 8 (one for positive plate, another is minus plate) to contact, and promptly circuit turn-on, display lamp 12 are bright; When cutting knife 1 passes skin to cavity the time, cutting knife 1 no longer bears counteracting force, and this moment, spring 6 resetted spring base 10, and puncture needle 2 is upspring; Pole plate 11 also resets thereupon, circuit disconnects, display lamp 12 goes out, bulletin people cutting knife 1 is in cavity, and then puncture needle 2 slowly is pushed forward into 1.5 centimetres, make and insert conduit 3 front ends and enter in the cavity, slowly outwards pull out puncture needle 2 again, the front end of inserting conduit 3 loses the support of puncture needle 2 and recovers to be mushroom 15, is stuck in the chamber wall; Treat that puncture needle 2 extracts moment, will insert conduit 3 afterbodys and clamp, and then insert the tail end of inserting conduit 3 with the joint of urinal or thoracic cavity drainage bottle, decontrol clamp, urine (or blood, gas) is promptly come out by drain.
