Description

Multipurpose umbrella shape entry needle

Technical field

The present utility model belongs to the apparatus of medium being inputted to human body, is specifically related to a kind of multipurpose umbrella shape entry needle for Wicresoft's interventional therapy under bronchoscope.

Background technology

Be that doctor obtains human pathology and diagnoses specimen and carry out the Main Means of Wicresoft's interventional therapy through endoscopic technic, its objective is in vitro and air flue and set up around between diseased region and derive or the occasional passage of introduction of substances.This special surgical technic can be realized percutaneous puncture and be difficult to the project of implementing.

Puncture needle is one of special utensil of interventional therapy under scope.Operate for different objects are special through the different size of specialized designs processing and the puncture needle of shape.As application number be 02258786.1 " breast sleeve-penetrating needle assembly ", application number be 95209505.X's " bladder air sac trocar ", application number is 002067196 " a kind of puncture trocar ", utility model and the patents of invention such as 200710113347.7 " disposable puncturing fistulization trocar ".

At present known all disclosed sleeve pipe needle sets through scope, all do not relate to the needle set that can sequentially carry out multinomial injection for curing and deep tumor, mediastinal lymph nodes puncture injection.When actual clinical operates, running into while needing the multinomial injection for curing at same position and deep tissue injection, have the problems such as puncture is difficult, needle point is easily deviate from tissue, affect the stability of injection operation, is a problem demanding prompt solution.

Utility model content

The purpose of this utility model be to provide a kind ofly there is beveled structure, can stably carry out deep tissue drug injection through endoscopic injection needle set.The technical solution of the utility model is: multipurpose umbrella shape entry needle comprise scalable umbrella shape pin, can be by the needle tubing of puncture needle, puncture needle needle handle and trocar sheath, described scalable umbrella shape pin is positioned at described puncture needle needle handle end, described can penetrating in described trocar sheath by the needle tubing of puncture needle, the inclined-plane of its front end and described scalable umbrella shape pin coincide.

Wherein, described scalable umbrella shape pin is that internal diameter is the hollow metal pin, collapsible and can be umbrella shape and open, most advanced and sophisticated sharp-pointed of 0.3mm to 0.6mm.

Wherein, described puncture needle needle handle is nickel alloy metal structure flexible, hollow, and length is 1.0 to 1.8 meters.

Wherein, described can be by the needle tubing of puncture needle, be hollow can be by the tubular structure of puncture needle, material is engineering plastics, length is 1.2 to 1.6 meters, can penetrate in trocar sheath, the inclined-plane of its front end and entry needle is identical.

Wherein, the plastic tube that described trocar sheath is hollow, material is engineering plastics, length is 1.2 to 1.6 meters.

This utility model, for obtaining pathological diagnosis tissue specimen through scope, completes through the thin puncture of scope pin and is difficult to the project realizing, easy and simple to handle, quick, safe, accurate, meets clinical demand.

Brief description of the drawings

Fig. 1 is this utility model structure chart,

Fig. 2 is this utility model umbrella shape entry needle end schematic appearance.

Detailed description of the invention

Be elaborated below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, concrete structure of the present utility model comprises scalable umbrella shape pin 1, can pass through needle tubing 2, puncture needle needle handle 3 and the trocar sheath 4 of puncture needle.

Described scalable umbrella shape pin 1 is positioned at described puncture needle needle handle 3 ends, can penetrate in described trocar sheath 4 by the needle tubing of puncture needle 3, and the inclined-plane of needle tubing 3 front ends and described scalable umbrella shape pin coincide.The metal thin tube that umbrella shape pin 1 is 0.5mm by internal diameter processes, and it is collapsible and can be umbrella shape opens, and the front end of pin becomes sharp-pointed needle point through grinding, firmly connects needle handle 3 at the root of pin, is beneficial to puncture in tissue.

Wherein, described can be by the needle tubing of puncture needle, be hollow can be by the tubular structure of puncture needle, material is engineering plastics, length is 1.2 to 1.6 meters, can penetrate in trocar sheath, the inclined-plane of its front end and entry needle is identical.Needle tubing is the hollow plastic pipe of 1.5 meters of length, and rear end flushes with the rear end of trocar sheath.

Wherein, described puncture needle needle handle 3 is nickel alloy metal structure flexible, hollow, and its front end is connected with umbrella shape hollow needle, and length is 1.0 to 1.8 meters.

The hollow plastic pipe that trocar sheath 4 is slightly larger than needle tubing 3 external diameters by internal diameter forms, and material is engineering plastics, and length is 1.2 to 1.6 meters.It and needle tubing 3 are isometric, and rear end can connect syringe, can be by bronchoscopic work duct.

While using operation, first entry needle suit is penetrated to scope work duct, guiding umbrella shape pin thrusts sufferer tissue with the suitable degree of depth, uses syringe to implement liquid medicine injection in apparatus rear end.

Due to the enforcement of technique scheme, this utility model utensil is had the following advantages:

1, can ensure the stability of entry needle in destination organization, the process of using is simple and convenient, easy operating.

2, rational in infrastructure, processing technique is simple, with low cost, easily implements.

3, while use, few, the accurate positioning, safe and reliable of tissue injury, can reduce surgical medical risk greatly.

4, can be used for the multiple endoscopic injection of drug such as bronchoscope, gastroscope, intestinal mirror.

The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the present utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
