Abstract

The invention belongs to the field of medical instruments, and particularly discloses a thoracocentesis mirror comprising a thoracocentesis mirror body and a sheath. The thoracocentesis mirror body comprises a needle-shaped hard working end, an operation portion, a light source connector, an image output end and a drainage passage which are communicated mutually. The sheath comprises a rigid sheath head and at least one passage and is disposed on the periphery of the needle-shaped hard working end; and a front end of the needle-shaped hard working end is provided with an optical lens and an optical fiber output end. The thoracocentesis mirror combines the advantage of a puncture needle capable of puncturing skins and tissue to get into a human body, and the advantage of an endoscope capable of providing inside view images for doctors; and when using the thoracocentesis mirror for puncture, the doctors no longer perform puncture depending on experience and judgment with certain blindness, but operate under direct view of a monitor, and accordingly operation safety is improved.

Description

A kind of thoracentesis mirror

Technical field

The invention belongs to field of medical appliances, specifically is the thoracentesis mirror.

Background technology

Puncture needle comprises the pin heart and needle stand, has scale, and it belongs to the interventional radiology equipment, and in the interventional radiology operation, skin puncture enters in the body with further guiding interventional radiology equipment.Present puncture needle is divided into: single wall puncture needle, the two parts trocars, the three parts trocars, atrial septal puncture pin and peeling puncture needle.

In addition, someone has also developed the patent No. is 201220024568.3, notification number is called a kind of utility model patent of thoracic puncture set for the CN202446544U name, this thoracic puncture set, include syringe, be connected the mozzle and the syringe needle that is connected on the mozzle of injector to inject mouth, syringe is provided with draining hole near the sidewall of an end of injection port; Described draining hole is provided with the first single-pass valve, and the first one-way valve door is connected with drainage bag by first mozzle; The injection port of described syringe is provided with the second single-pass valve, and the second one-way valve door is connected with syringe needle by second mozzle; The tip portion of described syringe needle is the arc needle point; The shank of described syringe needle partly is provided with scale.The degree of depth of can avoiding effectively having an acupuncture treatment is wayward, and needle point is stabbed the situation of patient pulmonary; Can also need not take off simultaneously syringe and realize the function of continuous drawing body fluid, reduce the fussy degree of work widely, improve work efficiency.But this puncture needle is when reality is used, and still needs to rely on doctor's judgement and experience to carry out for the puncture puncture position, has certain risk.Therefore, research and develop a kind of endoscope that in puncture needle, arranges, can monitor when solving lancet puncture that the thoracentesis mirror of problem of puncture situation is extremely urgent.

Summary of the invention

Technical purpose of the present invention is to overcome the deficiencies in the prior art, a kind of thoracentesis mirror is provided, this thoracentesis mirror makes the user also can obtain image simultaneously when finishing puncture effectively in conjunction with puncture needle advantage and endoscope's function, makes the user have better experience.

In order to reach above-mentioned technical purpose, the present invention realizes by following technical scheme:

A kind of thoracentesis mirror of the present invention, comprise puncture mirror main body and sheath pipe, described puncture mirror main body comprises needle-like hard work end, operating portion, light source joint, the output end of image that is interconnected and the drainage channel that is used for drain, described sheath pipe comprises hard sheath tube end and at least one passage, described sheath pipe places the periphery of needle-like hard work end, a soft pipeline in addition on this passage, the leading section of described needle-like hard work end is provided with optical lens and fiber-optic output.

In the present invention, the maximum gauge 15mm of described needle-like hard work end, length 30～150mm.

As the further improvement of above-mentioned technology, the leading section of described needle-like hard work end is the pin taper that has the inclined-plane, and described optical lens and fiber-optic output place the incline position of this pin taper, described pin taper length 20mm.

In order to have protective action preferably, the front end inclined-plane of described optical lens and fiber-optic output is provided with cover plate.

In the present invention, the diameter of described optical lens is more than or equal to 1.0mm, and its transmission system is fibre light guide system or glass optical system or electronics ccd optical system.

Described operating portion comprises pressing close to the assurance part of staff, and described drainage channel places on the operating portion.

Compared with prior art, the invention has the beneficial effects as follows:

Thoracentesis mirror of the present invention, combining puncture needle can skin puncture and the tissue advantage that enters human body, and endoscope can provide the advantage of doctor's internal view picture, when the doctor punctures by using the thoracentesis mirror, no longer rely on experience and judgement, have necessarily and carry out blindly, but under the direct-view of monitor, operate, improved the safety of operation.
