CN2105969U - Adjustable entering depth hollow probe - Google Patents

Abstract

The utility model relates to an endoscope injection needle with adjustable entering depth; the length of a tip of the present endoscope injection needle, which is extended out of a casing tube can only be determined before an operation; once determined, the length of the tip can not be altered in the process of the operation. The entering depth of the tip of the endoscope injection needle can not be regulated according to the actual circumstance of an affected part. The utility model is characterized in that a core tube head 5 and a casing tube head 2 form screw connection; the length of the tip extended out of the casing tube can be altered by rotating the core tube head 5; thus the entering depth of the tip to an affected part can be adjusted. The safety of therapy is enhanced.

Description

Adjustable entering depth hollow probe

This utility model relates to the auxiliary facilities of carrying out endoscopy and treatment usefulness in the body, particularly a kind of entry needle that cooperates therapeutic endoscopy to use.

Scope generally includes gastroscope, tracheascope, laryngoscope and intestinal mirror etc.With the gastroscope is example, and medical personnel stretch into patient throat with the head and the conduit of this equipment, and patient is swallowed, and operator observe it through eyepiece, this pipe is guided at leisure through esophagus go into stomach, at last scope is put into appropriate place.The typical use of scope is diagnosis upper digestive disease and gastric cancer, ulcer etc.Scope also is furnished with auxiliary facilities can carry out top layer sampling and treatment simultaneously, can perform a surgical operation in vivo in case of necessity.And injection for curing is an important component part in the therapeutic endoscopy, and liquid medicine injection is used when drawing when being used to diagnose or treating.Syringe external at present and that gastroscope is used can be divided into sleeve pipe and stamen pipe two parts, see accompanying drawing 1, wherein sleeve portion comprises that sleeve pipe 1 and casing head 2, stamen tube portion comprise transfusion stamen pipe 3, metal adapter 4 and stamen tube head 5, and 7 intercalations of injection needle point are at the front end of transfusion stamen pipe 3.With the ordinary syringe that liquid medicine is housed and stamen tube head 5 end to end just can with medicinal liquid through stamen tube head 5, metal take over 4, stamen pipe 3 and needle point 7 inject affected parts.During operation, the stamen pipe passes from sleeve pipe, and stamen tube head 5 props up casing head 2, and needle point stretched out telescopic length (promptly going out sheath length) L and was the degree of depth of thrusting affected part this moment, should meet the injection for curing requirement, and this length can be regulated by clip one section sleeve pipe in the end.This adjusting can only be carried out before operation, once determining, just can not change in operation process again, thereby can't regulate the degree of depth that entry needle thrusts at any time according to the concrete condition of affected part.And actual when carrying out injection for curing, can not determine very accurately to the injection site in advance, to the different parts in affected part, the degree of depth of thrusting also has nothing in common with each other, thereby fibrous root is regulated the degree of depth of thrusting of needle point according to situation about observing directly.But existing various entry needle all can not carry out this adjusting, not only influences therapeutic effect, and is also dangerous.

In addition, existing injection needle point all has only an inclined-plane, and sharp keen inadequately, the patient suffering is bigger.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, can regulate the scope entry needle that thrusts the degree of depth at any time according to the treatment needs and provide a kind of, and makes the injection needle point sharper keen.

The purpose of this utility model realizes in the following way: adopt thread connection between said stamen tube head and casing head, thereby can regulate the flexible of needle point.

In addition, sharper keen in order to make needle point, can respectively increase an inclined-plane in the both sides on the original inclined-plane of needle point, become by three inclined-planes and the needle point that the face of cylinder forms.Because of four ribs are arranged, also claim four-edged needle.

Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Accompanying drawing is the structural representation that scalable is thrust degree of depth scope entry needle.

Referring to accompanying drawing, the scope entry needle is divided into two parts, and outside sleeve portion comprises sleeve pipe 1 and the casing head 2 that expands.Inner stamen tube portion comprises stamen pipe 3 and stamen tube head 5 etc.Stamen tube head 5 front ends have pin thread 8, match with the female thread 10 of casing head 2, and turn stamen tube head 5 can change the two relative position, thereby reaches the purpose that needle point is elongated or shortened from sleeve pipe.The degree of depth that syringe needle thrusts affected part goes out the decision of sheath length L by needle point, so turn stamen tube head 5 degree of depth of thrusting affected part with regard to scalable needle point 7.

In order to cooperate in the operation, as shown in FIG., on stamen tube head 5, be provided with breeches pipe 9, so that inject haemostatic medicament simultaneously to the burst treatment of Massive Hemorrhage.

Use this scope entry needle, the situation that can arrive according to endoscopic views, Iterim Change thrusts the degree of depth, has improved the safety of treatment greatly, has also made things convenient for operation, has improved therapeutic effect.New syringe needle adopts three tiltedly to be convenient to thrust smoothly, reduces the operating time and alleviates patient's misery.

Claims (2)

1, a kind of therapeutic endoscopy entry needle comprises sleeve pipe 1, casing head 2, transfusion stamen pipe 3, metal adapter 4, stamen tube head 5 and injection needle point 7, it is characterized in that adopting thread connection between said stamen tube head 5 and the casing head 2.

2, entry needle as claimed in claim 1 is characterized in that said injection needle point 7 is made of three inclined-planes and a face of cylinder.
