Problems solved by technology

[0005] The purpose of the present invention is to overcome the intermittent electrocoagulation treatment of varicose veins in the prior art, and the intermittent electrocoagulation while withdrawing the tube manually, the insertion angle and withdrawal angle of the electrocoagulation head will deviate with the movement of the human hand, resulting in large wounds at the electrocoagulation site , In addition, the speed of intermittent electrocoagulation and switch electrocoagulation are easy to be improperly coordinated, resulting in poor coagulation effect. A coagulation instrument for minimally invasive treatment of varicose veins is provided, which can automatically withdraw the tube along a fixed path, and electrocoagulation The insertion angle and withdrawal angle are on a straight line, and the incision of the electrocoagulation site is small. At the same time, the moving component is used to cooperate with the switch electrocoagulation to control the retraction tube, so that the intermittent electrocoagulation operation is more accurate

Embodiment 1

[0047] Such as Figure 1-4 As shown, the present invention provides an electrocoagulation apparatus for minimally invasive treatment of varicose veins, the electrocoagulation apparatus includes an electrocoagulation catheter 1 and a base 2, the lower end surface of the electrocoagulation catheter 1 is provided with an electrocoagulation head 102, and the electrocoagulation catheter 1 is provided with metal conductive parts, and the outer peripheral wall of the electrocoagulation catheter 1 is provided with a conductive flange 101, and the conductive flange 101 is connected to the electrocoagulation head 102 through the metal conductive parts.

[0048] The base 2 is provided with a first through hole 201 through which the coagulation catheter 1 is inserted, and the inner peripheral wall of the first through hole 201 is provided with a groove 2011 cooperating with the conductive flange 101 along the axial direction. Extending downward in the axial direction, the groove wall of t...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is that the clamping assembly includes a chuck base 301, a chuck body 302, a small bevel gear 303, a large bevel gear 304, movable jaws 305 and a first motor, and the chuck body 302 is fixed on the chuck base 301, and the center of the chuck body 302 and the center of the chuck base 301 are provided with a second through hole coaxial with the first through hole 201; the side wall of the chuck body 302 is circumferentially A plurality of circular grooves are provided, the small bevel gear 303 is installed in the circular groove, the large bevel gear 304 is installed in the second through hole of the chuck body 302 and meshed with the small bevel gear 303, the large bevel gear The center of 304 is provided with the 3rd through hole that electric coagulation catheter 1 passes through, and the 3rd through hole is coaxial with the second through hole; The movable claw 305 is a plurality of, and the thread on the movable ...

Embodiment 3

[0066] The difference between this embodiment and Embodiment 2 is that the moving assembly in this embodiment also includes a first gear 502 and a drive motor 504 that drives the first gear 502 to rotate, and the top of the screw mandrel 401 is provided with a second gear coaxial with the screw mandrel 401 501, the first gear 502 meshes with the second gear 501 and drives the second gear 501 to rotate, and the first gear 502 is an incomplete gear.

[0067] Preferably, the drive motor in this embodiment is a servo motor. In this working process, if an ordinary motor is used to drive the second gear 501 to rotate, the electrocoagulation catheter will continue to move up during the upward movement process, and the servo motor can be used. short stay.

Abstract

The invention discloses an electrocoagulation instrument for a minimally invasive treatment of varicose veins. The electrocoagulation instrument for the minimally invasive treatment of the varicose veins comprises an electrocoagulation catheter and a base, an electrocoagulation head is arranged on the lower end surface of the electrocoagulation catheter, and a metal conductive member is arranged in the electrocoagulation catheter; a first through hole provided for insertion of the electrocoagulation catheter is formed in the base, a clamping component and a moving component are further arranged in the base, the clamping component is used for clamping the electrocoagulation catheter, and the moving component is used for vertically moving the electrocoagulation catheter axially along the first through hole; during using, the electrocoagulation catheter is inserted into the first through hole, the electrocoagulation head penetrates through the first through hole to the lower part of the lower end surface of the base, the clamping component clamps the electrocoagulation catheter, the moving component drives the electrocoagulation catheter to move axially downwards along the first through hole so that the electrocoagulation head penetrates through a blood vessel, and then the moving component drives the electrocoagulation catheter to move axially upwards along the first through holeto retract the catheter. Compared with the prior art, according to the provided electrocoagulation instrument for the minimally invasive treatment of the varicose veins, the catheter can be automatically retracted, intermittent electrocoagulation is realized, and operation is more accurate.

Description

technical field [0001] The invention relates to an electrocoagulation apparatus, in particular to an electrocoagulation apparatus for minimally invasive treatment of varicose veins. Background technique [0002] Varicose veins refer to tortuous and dilated veins due to factors such as blood stasis and weak venous walls. Varicose veins can occur in many parts of the body, and the most common place for varicose veins to occur is in the lower extremities. In the existing minimally invasive treatment of varicose veins, traditional thermal ablation techniques such as laser, microwave, and radio frequency are often used to achieve the purpose of sealing blood vessels by destroying blood vessels. [0003] Compared with traditional thermal ablation techniques, electrocoagulation therapy is a more effective treatment method. The use of electrocoagulation therapy for varicose veins is generally through puncture or incision, so that the electrocoagulation catheter is inserted into the...
