Abstract
The utility model provides a lung biopsy puncture outfit and belongs to the technical field of medical instruments. The lung biopsy puncture outfit is characterized in that the outer wall of the open end of a sleeve is in threaded sealing connection with a sealing cover, a puncture needle with the rear end flush with the inner wall of the cover face is fixedly connected onto the sealing cover, a square pull rod with the outer end connected with a handle penetrates the upper portion of the bottom of the sleeve and a matched square through hole and then is fixedly connected with a piston in the sleeve, and multiple sequentially-connected wedge-shaped clamp grooves are formed in the upper side of the square pull rod. The side wall of the bottom end of the sleeve is rotatably connected with a V-shaped supporting plate through a hinge pin, an arc-shaped elastic piece is connected between the left end of the V-shaped supporting plate and the sleeve side wall, a limiting plate is vertically fixed at the right end, and wedge-shaped structures matched with the wedge-shaped clamp grooves are arranged at the lower end of the limiting plate. The lung biopsy puncture outfit can prevent the pull rod from retracting and resetting and prevent the biopsy tissue from being pushed out. In addition, the puncture needle is integrally fixed with the sealing cover, separation of the puncture needle and a needle cylinder can be avoided, and smooth lung biopsy puncture can be ensured.
Description
Technical field: this utility model belongs to medical instruments technical field is a kind of lung biopsy perforator specifically.
Background technology; Lung puncture biopsy is the important means of obtaining clinically diagnosis basis, at present, mainly use clinically hollow needle to carry out aspiration biopsy by negative pressure-pumping, this hollow needle is after aspirate tissue, because cavity pressure is negative pressure, pintle is easy to reset and will organizes release; And piercing needle and syringe are that suit is fixing, in Biopsy process, piercing needle is easy to depart from syringe, causes Biopsy failure, to medical worker, has increased great work difficulty.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of when carrying out lung biopsy puncture to patient, not only can avoid piercing needle and syringe to depart from, and can also prevent the lung biopsy perforator that pintle retraction resets.
The purpose of this utility model is achieved in that this lung biopsy perforator comprises sleeve, seal cover, piercing needle, handle, square pumping rod, piston, " V " shape gripper shoe, limiting plate, the sleeve opening end outer wall thread seal cover that is being tightly connected, above seal cover, be fixedly connected with the rear end piercing needle concordant with capping inwall, the square pumping rod that outer end is connected with handle through the square through hole adapting with it above at the bottom of sleeve cylinder after with sleeve in piston be fixedly linked, square pumping rod upper side is provided with multiple connected wedge shape draw-in grooves successively; Sleeve cylinder bottom sidewall is being rotationally connected " V " shape gripper shoe by bearing pin, between " V " shape gripper shoe left end and sleeve lateral wall, is connected with arc elastic sheet, and right-hand member is vertically fixed wtih limiting plate, and limiting plate lower end is provided with the wedge structure adapting with wedge shape draw-in groove.
Advantage of the present utility model: carrying out to patient after lung biopsy puncture suction tissue, the fixation of limiting plate energy square shaped pumping rod, prevents that pumping rod retraction from resetting, and avoids biopsy to be pushed out; And piercing needle and seal cover are fixed as one, can avoid piercing needle and syringe to depart from, guarantee carrying out smoothly of lung biopsy puncture.
Accompanying drawing explanation: Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment: this utility model is described in further detail below in conjunction with Fig. 1: this lung biopsy perforator comprises sleeve 1, seal cover 2, piercing needle 3, handle 4, square pumping rod 5, piston 6, " V " shape gripper shoe 7, limiting plate 8, the sleeve 1 opening end outer wall thread seal cover 2 that is being tightly connected, seal cover 2 is being fixedly connected with the rear end piercing needle concordant with capping inwall 3 above, the square pumping rod 5 that outer end is connected with handle 4 through the square through hole adapting with it above at the bottom of 1, sleeve after with sleeve 1 in piston 6 be fixedly linked, square pumping rod 5 upper sides are provided with multiple connected wedge shape draw-in grooves successively, 1 bottom sidewall of sleeve is being rotationally connected " V " shape gripper shoe 7 by bearing pin, between " V " shape gripper shoe 7 left ends and sleeve 1 sidewall, be connected with arc elastic sheet 9, right-hand member is vertically fixed wtih limiting plate 8, and limiting plate 8 lower ends are provided with the wedge structure adapting with wedge shape draw-in groove.
