Description
Technical field
The utility model is related to medical instruments field, more specifically it relates to a kind of lung tissue puncture needle.
Background technology
Percutaneous lung puncture biopsy by application art is clinically more common diagnostic method, is widely used in lung's benign and malignant lesions
Diagnosis and discriminating., it is necessary to big swept-volume be done to the intrapulmonary focus for intending operation using image documentation equipments such as CT, according to focus before operation
Position and size, determine the optimum puncturing point and depth of needle and angle of wall of the chest outer skin.Can not be directly dynamic under conventional CT
Observe inserting needle situation, it is necessary to it is determined that behind entry point, depth of needle and inserting needle direction, puncture needle after the wall of the chest is pierced into lungs again
Secondary CT scan, confirms that needle point has reached lesion ideal position, patient is exited into the feasible aspiration biopsy in CT rears.Due to this technology
It is careless slightly to cause serious consequence for invasive operation.The generation of lung puncture complication and the qualification of operator, inserting needle time
The factor such as number, puncture needle and the acute angle degree and pulmonary emphysema of point of puncture pleura Tangented position is relevant.During operation, operator typically will first wear
Pricker, which is pierced into the wall of the chest and fixed using wall of the chest layer, needs repeated multiple times CT scan in puncture needle, art, punctured according in static image
The relative position of pin and intrapulmonary focus, orientation angle and depth of needle that constantly adjustment is punctured, it is ensured that puncture needle is finally accurately supported
Up to lesion tissue.
The puncture needle clinically used at present is divided into outside needle tubing and internal nook closing member two parts, and the effect of nook closing member is,
Before puncture needle is reached into diseased region through tissue, needle tubing is filled, prevents that non-target tissues or chip are stifled in operating process
Fill in needle tubing.Nook closing member and all metal materials of needle tubing are constituted, and total quality is larger.When puncture needle inserting needle and it is temporarily fixed to the wall of the chest
During layer repeats CT scan, the bearing down that heavier metal pintle is produced easily makes puncture needle deviate set puncture angle.
Utility model content
To solve problem above, the utility model provides a kind of lung tissue puncture needle, including hollow needle tubing and nook closing member,
The needle tubing includes Handheld Division and puncture portion, and the internal diameter of the Handheld Division is more than inside the puncture portion, the Handheld Division admittedly
Surely the first holder is connected with, first holder is connected with the elastomeric element under extended state, and the nook closing member is located at
The needle tubing is interior and blocks the front end of the needle tubing, and the rear end of the nook closing member has is fixedly connected with second on shackle, the shackle
Fluted at the position contour with the shackle in holder, the needle tubing, second holder props up the groove, so that
The nook closing member is withstood on to the front end of the needle tubing, the shackle is connected with the elastomeric element, in the wall of the groove it is hollow simultaneously
Destruction bar is provided with, the destruction bar front end exposes to be formed brokenly close to second holder, rear end from the Handheld Division afterbody
Bad button.
By using the puncture needle, inserting needle person, which only need to easily press destruction button 11, can vacate needle tubing for obtaining lung
Organize in portion.Also, due to significantly reducing the length of nook closing member so that the weight of the puncture needle is also greatly reduced, thus avoid because
For the displacement caused by the weight issue of puncture needle during inserting needle.
Further, the elastomeric element is spring.
Further, the length of the nook closing member is less than the 1/10 of the length of the needle tubing.
Further, the force-free state length of the elastomeric element is less than the 1/10 of the needle tubing length.
Further, multiple through holes are provided with the tube wall of the front end in the puncture portion.
Brief description of the drawings
Fig. 1 is the schematic diagram of lung tissue puncture needle of the present utility model.
In accompanying drawing, the list of parts representated by each label is as follows：
1st, needle tubing, 2, nook closing member, 3, shackle, 4, groove, the 5, second holder, 6, elastomeric element, 7, Handheld Division, 8, puncture
Portion, the 9, first holder, 10, destruction bar, 11, destruction button.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, the lung tissue puncture needle, including hollow needle tubing 1 and nook closing member 2, the needle tubing 1 includes Handheld Division 7
With puncture portion 8, the internal diameter of the Handheld Division 7, which is more than on the puncture portion 8, the inside of Handheld Division 7, is fixedly connected with first
Thing 9 is held, first holder 9 is connected with the spring 6 under extended state, and the nook closing member 2 is located in the needle tubing 1 and blocked up
The front end of the needle tubing 1 is filled in, the rear end of the nook closing member 2 has is fixedly connected with the second holder 5, institute on shackle 3, the shackle 3
State in needle tubing 1 with the contour position of the shackle 3 fluted 4, second holder 5 props up the groove 4, so that by institute
The front end that nook closing member 2 withstands on the needle tubing is stated, the shackle 3 is connected with the spring 6, it is hollow in the wall of the groove 4 and set
There is destruction bar 10, the destruction front end of bar 10 is close to second holder 5, and rear end exposes to be formed from the afterbody of Handheld Division 7
Destroy button 11.The length of the nook closing member 2 is less than the 1/10 of the length of the needle tubing 1.The force-free state length of the spring 6
Less than the 1/10 of the length of needle tubing 1.
During use, puncture portion is pierced into lesions position, before lesions position is reached, because nook closing member is supported by second
Thing withstands on needle tubing front end, protects needle tubing not blocked by non-purpose tissue or tissue debris.After inserting needle to lesions position, enter
Pin person need to only press destruction button, and destruction bar is pushed ahead, and destruction second is supported so that nook closing member is under the drive of spring close to hand
Portion's motion is held, and approaches needle tubing afterbody, so that hollow puncture portion is vacated, for obtaining lesion tissue.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
