Abstract

The invention relates to a lung puncture localization needle with the advantages of simple structure, low cost, operation convenience, low bleeding risk and high localization accuracy. The lung puncture localization needle consists of a needle core, a cannula and a sacculus tube, wherein the needle core and the sacculus tube can be inserted into the cannula; the sacculus tube is made of elastic fluorescent materials; the inside of the sacculus tube is hollow; a valve is arranged at an opening of one end; only the inward injection can be realized, but the automatic outward discharging cannot be realized; and the other end of the sacculus tube is connected with a sacculus, so that the sacculus expands or shrinks since air (or liquid) is injected into or extracted out from the opening. The needle core is inserted into the cannula to be tightly fit and is then pierced into the human body; the needle core reaches the focus through CT (Computerized Tomography) guidance; the needle core withdraws; the sacculus tube is inserted to the bottom; the air (or liquid) is inserted, so that the sacculus expands; then, the sacculus tube withdraws; the sacculus tube is left in the human body; and during subsequent operation, the focus can be localized by localizing the expanded fluorescent sacculus.

Description

Lung puncture positioning needle

Art

The present invention relates to the medically positioner of pulmonary lesionses, the preoperative CT of more particularly, to pulmonary's minimal disease draws Lead puncture positioning device.

Background technology

At present, clinically, pulmonary's minimal disease often needs preoperative positioning, and accurately lung tissue is judged in art to facilitate Excision extension, common pulmonary lesionses localization method mainly has Needle localization hook positioning, punctures dyeing positioning, punctures nucleic positioning Etc., there is respective technological deficiency in existing positioner：(1) location hook easily scratches peripheral vesselses, causes bleeding, art In be difficult to determine the accurate location of location hook and tumor by vision or tactile；(2) stain of dyeing positioning easily infiltrates Perienchyma, causes positioning inaccurate, is also difficult to find deep dyeing area on lung surface in art；(3) nuclear material of nucleic positioning Also easy wet periphery (perimeter) tissue, causes positioning inaccurate, while need various apparatuses supporting, complex operation.

The content of the invention

In order to solve above-mentioned technical problem present in prior art, the invention provides a kind of lung puncture positioning needle, should Positioning needle simple structure, easy to operate, accurate positioning, bleeding risk is little.

The technical solution adopted for the present invention to solve the technical problems is：A set of lung is constituted by nook closing member, sleeve pipe, balloon tube to wear Thorn positioning needle, the nook closing member includes handle and syringe needle, is made up of stiff materials；Described sleeve pipe includes base and socket, by hard Material is made, hollow form；The balloon tube includes flexible pipe and sacculus, is made up of elastic fluorescent material.

Further, the syringe needle of the nook closing member is sharp keen, slightly longer than the socket length of sleeve pipe, and diameter is slightly smaller than the pipe of sleeve pipe Cylinder, so that syringe needle can smoothly insert socket, and makes syringe needle slightly beyond socket, with profit puncture.

Further, flexible pipe one end connection sacculus of the balloon tube, is provided with the work of the salable mouth of pipe in another end opening Lobe, using syringe gas (or liquid) can be injected and extracted from.

Further, the balloon tube is in opening by being injected and extracted from gas (or liquid), expand can sacculus or Emptying retraction, to increase or decrease the volume of sacculus.

Further, the sacculus length of tube is longer than sleeve pipe, and diameter is slightly less than the socket of sleeve pipe, can make balloon tube (emptying State) smooth plug-in-sleeve.

Nook closing member plug-in-sleeve after agreeing with closely, can be easily pierced into thoracic wall by the present invention, and pulmonary's disease is proceeded under CT guiding Stove periphery, can now exit nook closing member, and Jing sleeve pipes insert balloon tube, sacculus (emptying state) side be inserted in human body when inserting, When sacculus (emptying state) reaches sleeve pipe distalmost end, then mean that sacculus (emptying state) has arrived at lung perilesional, now may be used With Jing sacculus tube openings side injection air (or liquid), sacculus is expanded, oppress surrounding soft tissue, so both can have been played only Blood is acted on, and reduces bleeding, sacculus (swelling state) can again be fixed on herein, for marked lesion accurate location.Now again Sleeve pipe is exited, by balloon tube indwelling in patient body, patient can find sacculus (expansion shape by touching in follow-up operation State), because balloon tube is made up of fluorescent material, patient can also observe by the naked eye the fluorescent places in tissue to determine focus Position.

The invention has the beneficial effects as follows：In operation, the sacculus with fluorescent effect of an expansion will be used than at present The material such as metal hook, stain, nucleic stain be more easy to detect and position；Due to the contention effect of sacculus, the wind of bleeding Danger is less；Simple structure, it is with low cost, it is easy to operate.

Description of the drawings

With reference to the accompanying drawings and examples the present invention is further described.

Fig. 1 is the structural representation of the nook closing member of the present invention；

Fig. 2 is the structural representation of the sleeve pipe of the present invention；

Fig. 3 is the structural representation (sacculus emptying state) of the balloon tube of the present invention；

Fig. 4 is the structural representation (sacculus swelling state) of the balloon tube of the present invention.

Below in conjunction with the accompanying drawings the invention will be further described.

Such as Fig. 1, shown in 2,3 and 4, the lung puncture positioning needle of the present invention, including nook closing member 3, sleeve pipe 6, balloon tube 10；Nook closing member 3 Including handle 1 and syringe needle 2, sleeve pipe 6 includes base 4 and socket 5, and balloon tube 10 includes flexible pipe 7, sacculus 8 and valve 9.

Handle 1 and syringe needle 2 are made by hard material, and are connected, and handle 1 is wider, is easy to operator Grip and push, syringe needle 2 is relatively thin, top is in needle-like, be easy to be pierced into tissue.

Base 4 and socket 5 are also to be made by hard material, are connected, and all in hollow form, inner hollow diameter compares syringe needle 2 diameters are bigger, and syringe needle 2 can be made to insert from the opening of base 4, and through base 4 and socket 5, the length of socket 5 is slightly less than syringe needle 2, with After the plug-in-sleeve 6 of nook closing member 3 is agreed with tightly, syringe needle 2 can just expose needle point.

Flexible pipe 7 and sacculus 8 are made and are connected by elastic fluorescent material, in hollow form, the diameter of flexible pipe 7 and syringe needle 2 It is identical, there is valve 9 at 7 one openings of flexible pipe, can inwardly be pushed open using syringe, but voluntarily can not open outwardly, flexible pipe 7 is another One connection sacculus 8.When sacculus 8 is in emptying state, balloon tube 10 may be inserted into sleeve pipe 6, after sacculus 8 expands, will be unable to pass through Sleeve pipe 6.The length of balloon tube 10 is more than sleeve pipe 6.

Specific embodiment

By the plug-in-sleeve 6 of nook closing member 3, after agreeing with tightly, Human Chest Wall is pierced into, under CT guiding lung perilesional is advanced into, Nook closing member 3 is then log out, sleeve pipe 6 remains in original position, the plug-in-sleeve 6 of balloon tube 10 of state will be vented in sacculus 8, treat sacculus When pipe 10 is inserted to 6 top of sleeve pipe, gas or liquid are injected with syringe from its valve 9, expand sacculus 8, finally exited Sleeve pipe 6, the sacculus 8 of expansion because making balloon tube 10 stay in human body and luminous by seeking expansion by surrounding tissue compressing wrapping Sacculus 8 positioning focus.
