the utility model provides a muscle tissue biopsy needle that punctures, including interior needle, outer needle and evacuating device, outer needle is used for the cover to establish the outside of interior needle, the tip of outer needle syringe needle with the tip of interior needle syringe needle aligns, just interior needle syringe needle with the cross-section direction of outer needle syringe needle is the same, evacuating device with interior needle is kept away from the one end sealing connection of syringe needle.
Preferably, the biopsy needle for muscle tissue aspiration further comprises a static sheet, and the static sheet is fixedly sleeved on the wall of the outer needle tube.
Preferably, the upper end surface of the static sheet is provided with angle scale marks.
Preferably, the side wall of the static sheet is provided with an anti-skid bulge.
Preferably, the anti-slip protrusions are strip-shaped protrusions.
Preferably, the vacuum-pumping device is a syringe.
Preferably, the inner needle head and the outer needle head are both offset-mouth type needle heads.
Preferably, the length of the inner needle is greater than the length of the outer needle.
The utility model discloses for prior art gain following technological effect:
the utility model provides a muscle tissue puncture biopsy needle, through establishing the outside at interior needle with outer needle cover, the tip of interior needle syringe needle aligns with the tip of outer needle syringe needle, and the cross-section direction of interior needle syringe needle and outer needle syringe needle is the same, pierce interior needle and outer needle simultaneously in the muscle tissue, utilize evacuating device including the needle formation negative pressure, muscle tissue gets into in the needle syringe needle, again with interior needle syringe needle rotation 180 degrees, outer needle keeps motionless simultaneously, from the muscle tissue in the disconnected interior needle, and at last, extract interior needle and outer needle. The process is simple to operate, and is beneficial to reducing the fear of patients and improving the working efficiency of medical workers; and the inner needle and the outer needle are beneficial to reducing trauma.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The utility model aims at providing a muscle tissue aspiration biopsy needle to solve the problem that prior art exists, can reduce wound and easy operation, be favorable to reducing patient's fear and feel and improve medical practitioner's work efficiency.
In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention is described in detail with reference to the accompanying drawings and the detailed description.
As shown in FIGS. 1-2: this embodiment provides muscle tissue biopsy needle, including interior needle 1, outer needle 2 and evacuating device, outer needle 2 is used for the cover to establish in the outside of needle 1, and the tip of 2 syringe needles on outer needle aligns with the tip of 1 syringe needle on the interior needle, and the cross-section direction of 1 syringe needle on interior needle is the same with 2 syringe needles on the outer needle, and evacuating device and the one end sealing connection of the syringe needle is kept away from to interior needle 1 for providing the negative pressure for interior needle 1, be convenient for inhale interior needle 1 with muscle tissue.
The working process is as follows:
in pricking muscle tissue with interior needle 1 and outer needle 2 simultaneously, utilize evacuating device 4 extraction interior needle gas, interior needle 1 inside negative pressure that forms for the muscle tissue of interior needle 1 cross-section department gets into in the needle head of interior needle 1, at this moment, with interior needle 1 needle head rotation 180 degrees, outer needle 2 keeps motionless simultaneously, with the muscle tissue in the disconnected interior needle 2, finally, extracts interior needle 1 and outer needle 2. Therefore, the muscle tissue acquisition process is simple to operate, and is beneficial to reducing the fear of patients and improving the working efficiency of medical workers; and the cross-sectional dimensions of the inner needle 1 and the outer needle 2 are small, which is beneficial to reducing the trauma of the patient.
The muscle tissue puncture biopsy needle also comprises a static sheet 3, wherein the static sheet 3 is fixedly sleeved on the tube wall of the outer needle 2 and used for limiting the depth of the inner needle 1 and the outer needle 2 penetrating into muscle tissue.
The upper end surface of the static sheet 3 is provided with angle scale lines 5, which is convenient for controlling the rotation angle of the inner needle 1.
The side wall of the static sheet 3 is provided with an anti-slip bulge to prevent slipping when the static sheet 3 is rotated by the side wall of the outer needle 2.
The anti-slip bulge is a strip-shaped bulge.
The vacuum pumping device is an injector 4, and has the advantages of convenience and easy availability.
The needle head of the inner needle 1 and the needle head of the outer needle 2 are both eccentric needle heads.
The length of interior needle 1 is greater than the length of outer needle 2, sets up like this, after obtaining the musculature, is convenient for extract interior needle 1 fast in outer needle 2, is favorable to further improving work efficiency.
The principle and the implementation mode of the present invention are explained by applying specific examples in the present specification, and the above descriptions of the examples are only used to help understanding the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the concrete implementation and the application scope.
