Description

Technical Field

[0001] The invention belongs to the field of single-action titanium clamps, and in particular relates to a single-action titanium clamp and a use method thereof. Background Art

[0002] Titanium clips are used to seal broken blood vessels during surgery. Doctors clamp the titanium clips with a single-action titanium clamp (detection titanium clamp) to deform the titanium clips and clamp the blood vessels.

[0003] The structure of the existing titanium clamp, such as the direct-view single-action titanium clamp of application number 201120057211.0, includes a handle consisting of a front handle and a rear handle connected in rotation, and a support spring sheet assembly is arranged between the front handle and the rear handle; the upper end of the rear handle is connected to the outer tube through a rotating wheel assembly, the rotating wheel assembly is rotatably connected to the rear handle, the outer tube is fixed to the rotating wheel assembly, and a push rod assembly is arranged in the outer tube with the rear end connected to the upper end of the handle. When the handle is closed, the push rod assembly moves forward, and a fixed clamp head is arranged at the front end of the outer tube, and a movable clamp head connected to the push rod assembly is arranged on one side of the fixed clamp head. When the push rod assembly moves forward, the movable clamp head closes to the fixed clamp head to clamp the titanium clamp. A flushing joint connected to the inner cavity of the outer tube is arranged on the rotating wheel assembly, and the flushing joint is connected to the flushing equipment through a hose. In the process of clamping the titanium clamp to the blood vessel, the flushing water enters the outer tube through the flushing joint and flows out from the front end of the outer tube to flush the surgical area and ensure a good surgical field of view.

[0004] According to the hospital's feedback, the existing titanium clamps have the following defects:

[0005] First, although the outer tube can be rotated by the rotating wheel assembly to rotate the movable and fixed clamp heads around the axis of the outer tube, so that the titanium clamp clamped between the movable and fixed clamp heads rotates accordingly, providing certain convenience for the titanium clamp to be smoothly clamped on the blood vessel, but this only has one adjustable degree of freedom, which is still not enough, because the distribution of blood vessels in the human body is strange, the space available for the titanium clamp to operate near different blood vessels is different, and the directions of different blood vessels are also different. The clamping direction of the movable and fixed clamp heads is fixed and always maintained in the axial direction of the outer tube, which is not conducive to the doctor adjusting the direction accordingly according to the actual situation of the operation, and is not conducive to smoothly clamping the titanium clamp on the blood vessel, and the operation is inconvenient.

[0006] Second, when the rotary wheel assembly is rotated, the hose connected to the flush joint twists accordingly, and the elastic force of the hose gives a certain torque to the rotary wheel assembly. During operation, the torque may explode, driving the rotary wheel assembly to rotate, and then the clamped titanium clamp rotates along with it, which is not conducive to the doctor's operation.

[0007] Therefore, the existing titanium clamps have the defect of being inconvenient to operate. Summary of the invention

[0008] The object of the present invention is to provide a single-action titanium clamp and a method for using the same. The present invention has the advantage of being easy to operate.

[0009] The technical solution of the present invention is as follows: a single-action titanium clamp comprises a handle consisting of a front handle and a rear handle, a supporting spring sheet assembly is arranged between the front handle and the rear handle, the upper end of the rear handle is connected to an outer tube through a rotating wheel assembly, a push rod assembly is arranged in the outer tube with a rear end connected to the upper end of the front handle, a fixed clamp head is arranged at the front end of the outer tube, a movable clamp head connected to the push rod assembly is arranged on the upper side of the fixed clamp head, a flushing joint connected to the inner cavity of the outer tube is arranged on the rotating wheel assembly, the fixed clamp head comprises a stator fixed to the outer tube, a stator and a rotor are arranged at the front end of the stator, and the stator and the rotor are rotatably connected to the stator through a vertical first pin shaft; the movable clamp head comprises a mover located on the upper side of the stator, the lower part of the mover is rotatably connected to the stator through a horizontal second pin shaft, the upper part of the mover is rotatably connected to the push rod assembly through a horizontal third pin shaft, a movable rotor is arranged at the front end of the mover, and the movable rotor is rotatably connected to the mover through a vertical fourth pin shaft.

[0010] In the aforementioned single-action titanium clamp, a vertical flat square through hole is provided on the stator, the bottom of the rear end of the mover extends into the flat square through hole, and the two ends of the second pin shaft are fixed to the side walls of the flat square through hole.

[0011] In the aforementioned single-action titanium clamp, a groove is provided at the rear end of the mover, the front end of the push rod assembly extends into the groove, and the two ends of the third pin are fixed to the side walls of the groove.

[0012] In the aforementioned single-action titanium clamp, a guide rod is provided between the movable rotor and the stator rotor, the lower end of the guide rod is fixed to the stator rotor, and the upper end of the guide rod passes through the stator rotor.

[0013] In the aforementioned single-action titanium clamp, a positioning wheel is provided at the rear end of the rotating wheel assembly, the upper end of the rear handle is bent forward and extended and threadedly connected to the positioning wheel, a plurality of slots are provided on the outer peripheral surface of the positioning wheel, a clamping head that cooperates with the slots is provided below the positioning wheel, the clamping head is hinged to the rear handle through a bracket, and a tension spring is provided between the bracket and the rear handle, and the tension spring presses the clamping head against the positioning wheel.

[0014] In the aforementioned single-action titanium clamp, the bracket is U-shaped, the front end of the bracket is fixed to the clamp head, the rear end of the bracket is hinged to the rear handle, the tension spring is located in the opening of the bracket, and an arc-shaped pull rod is provided at the bottom of the bracket, and the pull rod is located on the front side of the front handle.

[0015] In the aforementioned single-action titanium clamp, a clamping groove is provided at the upper end of the front handle, a ball head connected to the push rod assembly is provided in the clamping groove, a sealing ring is provided between the push rod assembly and the outer tube, and the sealing ring is located at the rear end of the outer tube.

[0016] In the aforementioned single-action titanium clamp, the clamping groove is a trapezoidal groove.

[0017] In the above-mentioned single-action titanium clamp, wave spring sheets are provided between the stator and the stator-rotor and between the mover and the movable rotor.

[0018] The method of using the aforementioned single-action titanium clamp is to lock the rotating wheel assembly by the chuck to prevent the outer tube from rotating freely; to separate the chuck from the wheel assembly by pressing down the pull rod so that the outer tube can rotate freely; to change the clamping angle of the fixed tongs and the movable tongs around the axis of the outer tube by rotating the wheel assembly, and to change the clamping angle of the fixed tongs and the movable tongs relative to the plane where the handle is located by rotating the stator and the movable rotor.

[0019] Compared with the prior art, the present invention mainly makes the following improvements on the basis of the existing titanium clamps.

[0020] First, the movable forceps head and the fixed forceps head are split structures, so that the front end of the movable forceps head and the front end of the fixed forceps head can rotate, which adds an adjustable degree of freedom, so that the doctor can adjust accordingly according to the actual distribution of the blood vessels, so that the operation is more convenient. Furthermore, by setting a guide rod, the movable rotor and the fixed rotor always keep synchronous rotation, and no misalignment occurs. The titanium clip clamped between the movable and fixed rotors is not easy to fall off, creating favorable conditions for the smooth progress of the operation. In addition, by setting a wave spring sheet between the stator and the stator and between the mover and the movable rotor, a friction resistance is established between the stator and the stator and between the mover and the movable rotor, preventing the stator and the movable rotor from rotating freely after the angle adjustment is completed, avoiding the uncontrolled rotation of the clamped titanium clip, and further facilitating the doctor's operation.

[0021] Second, a positioning wheel is arranged at the rear side of the rotating wheel assembly, a card slot is arranged on the outer peripheral surface of the positioning wheel, a card head cooperating with the card slot is arranged below the positioning wheel, the card head is connected to the rear handle through a bracket, and the card head is engaged in the card slot under the action of a spring to prevent the positioning wheel from rotating. Accordingly, the rotating wheel assembly will not be twisted under the action of the twisted hose on the flushing joint, preventing the uncontrolled rotation of the moving and fixed clamps, making the operation of the doctor convenient. When rotating the rotating wheel assembly, the doctor holds the handle with one hand, and the finger hooks the pull rod to separate the clamp head from the positioning wheel, so that the other hand can rotate the rotating wheel assembly. After the rotation is completed, the hand is released, and the clamp head will automatically connect to the positioning wheel to keep the rotating wheel assembly from rotating. The operation is also very convenient, and the needs of ergonomics are fully considered.

[0022] In summary, the present invention has the advantage of convenient operation. BRIEF DESCRIPTION OF THE DRAWINGS
