Abstract

The utility model discloses Small pulmonary nodule operation consent CT positioning set, including puncture needle and seal wire, and the outer needle outer wall of puncture needle is marked along the first length scale label, seal wire surface is axially arranged with along the second length scale is axially arranged with；The first length scale label is corresponded to each other with the second length scale label；Mutual corresponding length scale label is set on the outer needle and seal wire of puncture needle, on the one hand intuitively paracentesis depth can be observed when puncturing, on the other hand, when carrying out the release of spring ring, depth of the seal wire outside puncture needle in needle is apparent that by length scale label, to which spring ring is accurately released to Small pulmonary nodule position, artificial manipulation bring error is eliminated, guarantees the accuracy of operation.

Description

Small pulmonary nodule operation consent CT positioning set

Technical field

The utility model relates to the field of medical instrument technology, specifically a kind of Small pulmonary nodule operation consent CT positioning set.

Background technique

It is more and more to be difficult to qualitative lung's submillimeter level lesser tubercle quilt with the development of high-resolution ct scanning technique It was found that the raising of Minimally Invasive Surgical Technology in recent years, carries out local lesion's excision by thoracoscope and is possibly realized.But pulmonary nodule Consolidation after smaller, lung tissue compression, it is difficult to instruct lesser tubercle to cut off by palpation, the excision wound of the lobe of the lung or lung section is too big, because The positioning of this Small pulmonary nodule is most important.

Positioning for Small pulmonary nodule, more commonly used at present is using spring ring positioning method, according to disease before positioning Stove position selects suitable position, and body surface symbol is first affixed on corresponding position, and under the guidance of CT thin layer scanning, selection is best Path, angle, are punctured, and are placed in spring ring in puncture needle by seal wire after puncture, but in release spring circle, are needed After spring ring is all pushed into intrapulmonary with seal wire, then puncture needle is exited into completion and is positioned.

In this operating process, since puncture needle is located in vivo, the position for loseing spring ring is just looked at, so cannot be accurate Know push-in depth, and both hands want blocked operation, can only about nip seal wire with hand when needing hand-off penetrates position Set, when gain manipulator continue operation when, penetrate position and deviation just unavoidably occur；This results in the release position of spring ring Inaccuracy is set, Small pulmonary nodule is this may result in when spring ring positioning is partially shallow and is not removed, and if spring ring positioning is inclined It will lead to cut off excessive lung tissue when deep, bring unnecessary injury to patient.

Utility model content

The purpose of this utility model is to provide a kind of Small pulmonary nodule operation consent CT positioning sets, which can Spring ring is accurately released to Small pulmonary nodule position, artificial manipulation bring error is eliminated, guarantees the accuracy of operation.

The technical scheme adopted by the utility model to solve the technical problem is as follows:

The outer needle outer wall of Small pulmonary nodule operation consent CT positioning set, including puncture needle and seal wire, puncture needle is set along axial direction There is the first length scale label, seal wire surface is marked along the second length scale is axially arranged with；First length scale label with Second length scale label corresponds to each other.

Further, the first length scale label is all made of full-length scale with the second length scale label.

The utility model has the beneficial effects that mutual corresponding length scale is arranged on the outer needle and seal wire of puncture needle On the one hand label can intuitively observe paracentesis depth when puncturing, on the other hand, in the release for carrying out spring ring When, depth of the seal wire outside puncture needle in needle is apparent that by length scale label, thus accurately by spring ring It is released to Small pulmonary nodule position, artificial manipulation bring error is eliminated, guarantees the accuracy of operation.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples:

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the enlarged diagram of the outer needle of the utility model puncture needle；

Fig. 3 is the partial enlargement diagram of the utility model seal wire.

Specific embodiment

As shown in Figure 1, the utility model provides Small pulmonary nodule operation consent CT positioning set, including puncture needle 1 and seal wire 2, puncture needle 1 includes outer needle 1a and interior needle 1b, and as shown in connection with fig. 2, the outer wall edge of outer needle 1a is axially arranged with the first length scale Label 3, as shown in connection with fig. 3,2 surface of seal wire edge are axially arranged with the second length scale label 4；The first length scale label 3 It is corresponded to each other with the second length scale label 4.Preferably, the first length scale label 3 is all made of with the second length scale label 4 Full-length scale.

It is affixed on corresponding lesions position in use, body surface is developed and positions grid, under the guidance of CT thin layer scanning, selection Optimal path, angle, are punctured using puncture needle, since the outer wall of outer needle 1a is equipped with the first length scale label 3, so It can understand and intuitively paracentesis depth is observed；After puncture, extracts interior needle 1b out, be placed in spring ring by seal wire 2 In outer needle 1a, seal wire 2 is then promoted, spring ring is made to be released to Small pulmonary nodule position；Since 2 surface of seal wire is equipped with the second length Scale mark 4 is spent, depth of the seal wire outside puncture needle in needle can be known clearly by the second length scale label 4, thus Spring ring is accurately released to Small pulmonary nodule position, artificial manipulation bring error is eliminated, guarantees the accuracy of operation.

The above descriptions are merely preferred embodiments of the present invention, not makees in any form to the utility model Limitation；Anyone skilled in the art, it is all available in the case where not departing from technical solutions of the utility model ambit The methods and technical content of the disclosure above makes many possible changes and modifications to technical solutions of the utility model, or is revised as The equivalent embodiment of equivalent variations.Therefore, all contents without departing from technical solutions of the utility model, according to the utility model Technical spirit any simple modification, equivalent replacement, equivalence changes and modification made to the above embodiment are still fallen within practical In the range of the protection of new technique scheme.

Claims
