Abstract

The utility model belongs to the field of medical instruments, and particularly relates to an abdominocentesis endoscope. The abdominocentesis endoscope comprises an abdominocentesis endoscope body and an expansion sheath tube, wherein the abdominocentesis endoscope body comprises a needle-shaped rigid working end part, an operation part, a light source connector and an image output end, at least one inflation or airbag catheter access channel is formed in the expansion sheath tube, and the expansion sheath tube is arranged on the periphery of the needle-shaped rigid working end part. According to the abdominocentesis endoscope, the advantage of a puncture needle and the function of an endoscope are effectively combined, namely the advantage, of the puncture needle, that the puncture needle can puncture the skin and tissue to enter the human body and the advantage, of the endoscope, that the endoscope can provide an internal view image for a doctor are combined, the abdominocentesis endoscope can be used by the doctor to directly puncture a target portion to enter the gas expansion abdominal cavity through the inflation channel, abnormal conditions, such as bleeding, can be found conveniently in a direct vision mode, more objective and more visual materials are provided for the doctor, and the doctor can make diagnosis and treatment conveniently.

Description

A kind of abdominal paracentesis mirror

Technical field

This utility model belongs to field of medical appliances, specifically the abdominal paracentesis mirror.

Background technology

Puncture needle, comprise the pin heart and needle stand, and with scale, it belongs to the interventional radiology equipment, and in the interventional radiology operation, skin puncture, enter in body further to guide the interventional radiology equipment.Present puncture needle is divided into: single wall puncture needle, the two parts trocars, the three parts trocars, Interaurcular septum puncture needle and peeling puncture needle.in addition, someone has also developed a kind of patent No. is CN201110175712.3, notification number is CN102283695A, name is called retraction type laparoscope puncture mirror, comprise that cross section is circular sheath body and core bar, described sheath body has the column type cavity near rear end, in described cavity one side, core bar positioning mechanism is set, described core bar rear end arranges round hole clipping groove, the hole clipping groove coordinates with the kelly of core bar positioning mechanism end, described core bar terminal horizontal connects the second spring part, described the second spring part other end level is fixedly connected on Connection Block, T-shaped push rod and Connection Block are used in conjunction with, Connection Block (pushes away between seat and column type cavity at T-shaped push rod.This perforator have can avoid to abdominal cavity or thoracic organ and muscular tissue cause secondary injury may, but this puncture needle is when reality is used, and for the puncture puncture position, still needs to rely on doctor's judgement and experience to carry out, and has certain risk.Therefore, research and develop a kind of endoscope that arranges in puncture needle, can monitor when solving lancet puncture that the abdominal paracentesis mirror of problem of puncture situation is extremely urgent.

The utility model content

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

In order to reach above-mentioned technical purpose, this utility model is realized by following technical scheme:

A kind of abdominal paracentesis mirror described in the utility model, comprise puncture mirror main body and expansion sheath pipe, described puncture mirror main body comprises needle-like hard work end, operating portion, light source joint and output end of image, described expansion sheath pipe comprises sheath tube end and at least one inflation or balloon catheter access way, and described sheath tube end is placed in the periphery of needle-like hard work end.

As the further improvement of above-mentioned technology, the leading section of described needle-like hard work end is for being with bevelled pin taper, and described optical lens and fiber-optic output are placed in the incline position of this pin taper; This pin taper length 20mm, the front end inclined-plane of described optical lens and fiber-optic output is provided with cover plate.

In this utility model, the maximum gauge 15mm of described needle-like hard work end, length range is 30-150mm.

In this utility model, 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.

In this utility model, described operating portion comprises pressing close to the assurance part of staff.

Compared with prior art, the beneficial effects of the utility model are:

Abdominal paracentesis mirror described in the utility model, 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, the doctor uses the abdominal paracentesis mirror directly in the target site puncture, to enter through filling channel injecting gas expansion abdominal cavity, the lower unusual circumstance of convenient direct-view, as hemorrhage etc., for the doctor provides more objective, material intuitively, so that the doctor makes diagnosis and treatment.
