Description

Disposable bracket for fixing percutaneous aspiration biopsy needle and radio frequency treatment needle

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a disposable bracket for fixing a percutaneous aspiration biopsy needle and a radio frequency treatment needle.

Background

Percutaneous aspiration biopsy refers to a method of positioning under the guidance of a B-type ultrasonic apparatus, CT guidance or X-ray fluoroscopy, puncturing a lesion part with a biopsy needle, extracting a part of cells or tissues, and then performing pathological examination on the lesion cells or tissues. The percutaneous puncture radio frequency thermal coagulation treatment is that the electromagnetic heat energy generated by electromagnetic waves is applied to cause tissue coagulation necrosis so as to achieve the purpose of inactivating tumors or other tissues, and the treatment approaches include 3 percutaneous, laparoscopic and open abdominal operations. At present, percutaneous aspiration biopsy and percutaneous aspiration radio frequency thermosetting treatment are widely applied to clinical medicine, and complications caused by displacement or slippage of an aspiration needle in the operation process are reported, and the consequences are serious once the complications occur.

The main links of puncture needle shift or slippage in percutaneous puncture biopsy and percutaneous puncture radio frequency thermosetting treatment are as follows: 1. the CT guided needle inserting and positioning process of the puncture biopsy: when the CT machine scans, the body of a patient is positioned in a narrow space of a scanning channel of the CT machine, an operator cannot hold the puncture needle by hand for fixation in the whole process, and the puncture needle can be supported only by means of articles such as dressing and the like; 2. the treatment time of some parts can be more than 12 minutes by percutaneous puncture radio frequency heat coagulation treatment. In the above links, if the operator only holds the puncture needle manually, the risk of displacement of the needle tip is greatly increased. Therefore, the invention is urgently needed to invent a device which can effectively fix the puncture needle and reduce the displacement of the needle point.

Preferably, the bracket body is further provided with a graduated scale, and the graduated scale is located on the outer side of the fixing groove.

Preferably, one end of the fixer is provided with a clamping groove with an outward opening, and the other end of the fixer is provided with a mounting hole.

Preferably, the puncture needle is clamped in the clamping groove.

Preferably, the fixing member includes a bolt and a nut, and the bolt passes through the fixing groove and the fixing member in sequence and is fixed by the nut.

Preferably, the bottom of the chassis is provided with a double-sided sticker.

Preferably, the holder and the bracket body are made of a polymer material.

The utility model discloses possess following beneficial effect:

the utility model provides a new idea for reducing the displacement of the needle tip in the puncture process.

Secondly, this utility model, the macromolecular material is all chooseed for use to the fixer and the bracket body and is makeed, and the dead weight is light, can not cause the oppression to patient's health.

Thirdly, the bottom of the bracket body is pasted on the skin of the patient by using double-sided paste, the bottom has a larger area and is more stably fixed; the bracket body is designed with double tracks and double channels, and the puncture needle can be stably fixed.

Fourthly, this utility model, the preparation has the scale on the bracket body, when fixed pjncture needle, can carry out the judgement of pjncture needle height.

fig. 2 is a schematic structural view of the middle fixer of the present invention.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-2, a disposable bracket for fixing a percutaneous biopsy needle and a radio frequency treatment needle includes a holder 1, a fixing member 2, a bracket body 4 and a chassis 5.

Wherein, 5 edges on foretell chassis are arc, the chassis is directly pasted to skin, arc be difficult to stab the pain patient, bracket body 4 sets up in 5 upper surface one sides on chassis, form crease 9 between bracket body 4 and the chassis 5, it is convenient when using, only need from middle crease 9 department turn over into ninety degrees use can, bracket body 4 has seted up two ascending fixed slots of opening 8, fixed slot 8 sets up along 4 length direction of bracket body, can realize that the fixer reciprocates along 4 length direction of bracket body, and then adjust the position of fixer 1, mounting 2 passes through fixed slot 8 and can dismantle the connection on bracket body 4 with fixer 1, convenient fixed pjncture needle.

The bracket body 4 is also provided with a graduated scale 3, the graduated scale 3 is positioned outside the fixed groove 8, and the puncture needle can be fixed and the height of the puncture needle can be judged at the same time.

The clamping groove 11 with the outward opening is formed in one end of the fixer 1, the puncture needle 7 is clamped in the clamping groove 11, and the mounting hole 12 is formed in the other end of the fixer 1, so that the puncture needle 7 can be conveniently clamped, and the fixer 1 can be conveniently and stably mounted on the bracket body 4.
