Abstract
The utility model discloses an endocardium myocardium biopsy forceps sheath tube with an arc-shaped elbow, which comprises a sheath tube, wherein one end of the sheath tube is connected with a rotating button and a three-way piece, the other end is an arc-shaped elbow, an intervention channel is arranged in the three-way piece, the rotating button and the sheath tube in a penetrating way, one end of the intervention channel at the top of the three-way piece forms a bayonet, one end of the intervention channel at the arc-shaped elbow forms a guide port, the bayonet is provided with a hemostatic valve, one side of the three-way piece is provided with a flushing pipe connected with the intervention channel, the opening end of the flushing pipe is provided with a flushing valve, the sheath tube is designed into a natural arc shape according to the included angle between the right internal jugular vein and the right ventricle, so that the arc-shaped elbow sheath tube can be conveniently pushed according to the path of the natural radian of the right internal jugular vein, the house, the tricuspid valve and the right ventricle of a human body, and the front end of the sheath tube is an elbow, thereby reducing the resistance in pushing, can successfully complete the task of sampling.
Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to arc elbow endocardium myocardium biopsy forceps sheath pipe.
Background
At present, clinical intracardiac biopsy through right internal jugular (femoral) vein intervention is widely applied, generally endocardial myocardium biopsy forceps are used, the biopsy forceps are pushed to the right atrium through the tricuspid valve to reach the right ventricular contact chamber interval through the right internal jugular vein or femoral vein forceps under DSA, the biopsy forceps are quickly closed to take out micro tissues, the micro tissues are taken out of a body, and a sheath canal access is not used generally.
However, at present, under the condition of not using a sheath tube, the difficulty of pushing the biopsy forceps to the right ventricle through the right internal jugular vein or the femoral vein is very high, the technical requirement is extremely high, even a doctor who is high in capital age is challenging, errors can occur, heart injury is caused, pain is brought to a patient, and doctor-patient disputes occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a technical scheme does: the utility model provides an arc elbow endocardium myocardium biopsy forceps sheath pipe, includes the sheath pipe, sheath pipe one end is connected with knob, tee bend spare, and the other end is the arc elbow, run through to be equipped with in tee bend spare, knob, the sheath pipe and intervene the passageway, the one end that intervenes the passageway and be located the tee bend top forms the bayonet socket, the one end that intervenes the passageway and be located the arc elbow forms the silk mouth of leading, bayonet socket department is equipped with hemostatic valve, tee bend spare one side is equipped with and intervenes the flushing pipe of passageway connection, the flushing pipe open end is equipped with the flushing valve.
As an improvement, the arc-shaped elbow is a soft elbow.
After the structure more than adopting, the utility model has the advantages of as follows: the utility model designs the sheath tube into a natural arc shape according to the included angle between the right internal jugular vein and the right ventricle, which is convenient for the arc-shaped elbow sheath tube to be pushed along the natural radian route of the right three right sides (right internal jugular vein, right atrium, tricuspid valve and right ventricle) of the human body; the radian of the sheath tube can be controlled by advancing and retreating the sheath core; the front end of the sheath tube is an elbow, so that the resistance in pushing is reduced; finally, the arc-shaped elbow sheath tube passes through the right internal jugular vein → the right atrium → the tricuspid valve → the right ventricle to smoothly reach the interventricular septum, and the biopsy forceps are inserted into the arc-shaped elbow sheath tube to smoothly complete the task of sampling.
Drawings
Fig. 1 is a schematic structural view of the sheath tube of the endocardium myocardial biopsy forceps with an arc-shaped elbow.
Fig. 2 is a schematic view of the internal structure of the sheath tube of the endocardium myocardial biopsy forceps with the arc-shaped elbow.
As shown in the figure: 1. sheath pipe, 2, knob, 3, tee bend spare, 4, arc elbow, 5, intervention passageway, 6, bayonet socket, 7, wire guide mouth, 8, hemostasis valve, 9, wash pipe, 10, the flashing valve.
Detailed Description
Combine the attached drawing, an arc elbow endocardium cardiac muscle biopsy forceps sheath pipe, including sheath pipe 1, 1 one end of sheath pipe is connected with knob 2, tee bend piece 3, and the other end is arc elbow 4, it intervenes passageway 5 to run through being equipped with in tee bend piece 3, knob 2, the sheath pipe 1, the one end that intervenes passageway 5 and be located tee bend 3 top forms bayonet socket 6, the one end that intervenes passageway 5 and be located arc elbow 4 forms guide wire mouth 7, 6 departments of bayonet socket are equipped with hemostasis valve 8, 8 one side of tee bend piece is equipped with the wash pipe 9 of being connected with intervene passageway 5, 9 open ends of wash pipe are equipped with wash valve 10.
As a preferred embodiment of this embodiment, the curved elbow is a soft elbow.
The utility model belongs to intracardiac biopsy technique of interveneeing clinically the utility model discloses in, form a natural arc with the sheath pipe according to the contained angle of right internal jugular vein and right ventricle, can control sheath pipe radian along with the advance and retreat of the sheath core at center, and the sheath pipe front end is the elbow, and the propelling movement passes right atrium → tricuspid valve → right ventricle can be more homeopathic like this, and little elbow reduces the resistance in the propulsion, and arc elbow sheath pipe reaches the room interval, and biopsy forceps alright reachs smoothly, and the pincers sample originally accomplishes the task.
The utility model discloses when specifically setting up, the sheath pipe that will have 8F now is according to the cold shaping of arc elbow mould heat, establishes to soft elbow at sheath pipe front end, the seal wire control of being convenient for to make the advance and retreat of sheath core can control sheath pipe radian, when using, sheath pipe and endocardium myocardium biopsy forceps supporting use, and can design the arc elbow sheath pipe model of different length according to human height.
The arc elbow clamp sheath tube passes through the right internal jugular vein or femoral vein, the radian of the sheath tube can be controlled through the advancing and retreating of the sheath core, the operation of entering the right ventricle according to the natural arc path of the right internal jugular vein and the right ventricle can be simple and standard, the success rate is higher, the risk is lower, the passive situation that the special sheath tube for endocardial myocardium biopsy clamp is not available at present is changed, and the arc elbow clamp sheath tube is welcomed by patients and medical staff.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
