Abstract
The utility model discloses a puncture needle for positioning via CT guiding before a lung node cutting operation. The puncture needle comprises a needle body, a pre-buried ball capsule and a conducting wire, wherein a cavity is arranged in the needle body; one end of the cavity opens in a needle tail place; the other end of the cavity opens on a side surface of a needle point; the pre-buried ball capsule is placed in the cavity; the conducting wire is connected with the pre-buried capsule via a port of the ball capsule and extends out of the open in the needle tail; at a contraction state, the pre-buried ball capsule is arranged in the cavity; and at an expansion state, the port of the pre-buried ball capsule tightens and protrudes out of the cavity and stays outside of the needle body. A ball capsule structured in lung parenchyma facilitates positioning via hand touch during an operation, so excision depth is clarified and accurate excision is achieved; the conducting wire staying on the surface of a lung layer pleura can clearly guide positioning via naked eyes of a surgeon; and resistance is formed between the expanded ball capsule and surrounding lung parenchyma, so ball capsule displacement or falling off is uneasy to happen when a patient carries or the conducting wire is pulled and needle passage bleeding and a complication like pneumothorax during the operation are reduced.
Description
Technical field
This utility model belongs to medical instruments field, particularly a kind of puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity.
Background technology
Along with the extensive use of multi-detector CT, find clinically increasing solitary pulmonary nodule (Solitary pulmonary nodule, SPN).The Findings of SPNs comprises reality tuberosity, part reality tuberosity and ground glass sample pathological changes (Ground glass opacity, GGO).Along with the development of thoracoscope technology (Video-assisted thoracoscopic surgery, VATS), not only Wicresoft, safety of wedge resection of lung under VATS, and can reach the object of Clinics and Practices simultaneously.For diameter, be less than the SPNs of 20mm, especially position is main focus at, the GGO of take deeply, and in operations research, naked eyes are difficult to find, with hands, be difficult to touch, and are difficult to accurately excision under thoracoscope, affect the success rate of VATS.How in the preoperative SPNs to be located is accurately the difficult problem that urgent clinical needs solve.Current preoperative localization method comprises CT guide wire hook location, injection methylene blue staining, injectable collagen or agar colloidal sol and injection Radioactive isotope etc., and the alone or coupling of these methods all exists following major defect: (1) is inadequate to the accuracy of perusal location.Stain diffusion etc. may appear that the displacement of preoperative metal hook comes off or in existing method, causes in art accurately locating; (2) the lung tissue quality of injection stain or radioactive indicator, without obvious change, causes the tangible property of detecting in art inadequate.
Utility model content
For overcoming above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity.
For achieving the above object, this utility model provides following technical scheme: a kind of puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity, comprises the needle body, pre-buried sacculus and seal wire; Wherein, the inside of the needle body arranges cavity, and one end of cavity is opened on backshank, and the other end is opened on the side of needle point; Pre-buried sacculus is positioned at cavity; Seal wire is connected with pre-buried sacculus by the bag mouth of pre-buried sacculus, and stretches out from being positioned at the opening part of backshank;
Described pre-buried sacculus is preferably placed in the cavity of needle point side opening part;
Described needle point is ramp structure, is conducive to inserting needle;
The described needle body is marked with graduation mark;
The numerical optimization of described graduation mark increases progressively with 1cm;
The length of the described needle body is preferably 10cm;
Described pre-buried sacculus is positioned at cavity when contraction state, by its bag mouth, is connected with seal wire;
Described pre-buried sacculus bag mouth after expansion tightens up, outstanding from cavity, is positioned at the outside of the needle body.
Described seal wire is marked with graduation mark;
The numerical optimization of described graduation mark increases progressively with 1cm; More preferably with 1cm, be incremented to 10cm.
This utility model has following advantage and effect with respect to prior art:
(1) balloon structure that the puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity that this utility model provides produces in pulmonary parenchyma, helps the life of the Rhizoma Atractylodis Macrocephalae traditional Chinese medical science and touches location with hands, defines the position of excision, reaches the object of accurate excision.
(2) puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity that this utility model provides is by resting on the seal wire with scale of lungs layer pleural surface, and the surgical naked eyes of clear guide are located and the excision degree of depth.
(3) what this utility model provided guides the dilating sacculus of lower puncture needle of locating and between pulmonary parenchyma, forms resistance around for the preoperative CT of pulmonary's tuberosity, is not prone to sacculus displacement or comes off when patient transporting or seal wire are subject to tractive.
(4) puncture needle for the lower location of the preoperative CT of pulmonary's tuberosity guiding that this utility model provides is due to the compressing of dilating sacculus, thereby it is hemorrhage and wait in operation process the complication such as pneumothorax to reduce needle track.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1
As shown in Figure 1, a kind of puncture needle for the lower location of the preoperative CT guiding of pulmonary's tuberosity, comprises the needle body 3, pre-buried sacculus 2 and seal wire 6; Wherein, the inside of the needle body 3 arranges cavity 4, and one end of cavity 4 is opened on backshank 5, and the other end is opened on the side of needle point 1, and needle point 1 is ramp structure, is conducive to inserting needle; Pre-buried sacculus 2 is positioned at the cavity 4 of needle point side opening part; Seal wire 6 is connected with pre-buried sacculus 2 by the bag mouth of pre-buried sacculus 2, and stretches out from being positioned at the cavity opening part of backshank 5, and part is exposed to outside the needle body 3.
As shown in Figure 2, when pre-buried sacculus 2 shrinks, the bag mouth of pre-buried sacculus 2 becomes open state, and bag mouth is connected with seal wire 6; As shown in Figure 3, when pre-buried sacculus 2 expands, the bag mouth of pre-buried sacculus 2 shrinks, narrows down, and bag mouth is connected with seal wire 6.
