Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a vascular suture fixing device. Background Art
[0002] The vascular suture device is a surgical instrument used to suture blood vessels. Under normal circumstances, the suturing process is to first send the angiographic guide wire into the artery through the sheath, then remove the arterial sheath, and then send the vascular suture device along the guide wire into the artery, push the suture device until there is pulsating blood spurting out of the marker tube, withdraw the guide wire, then open the support foot control sense to make it open in the blood vessel, and gently return the suture device until there is resistance and the blood flow in the marker tube stops, withdraw the needle plug to lead out two sutures and cut them, restore the support foot control lever, withdraw the suture device until the suture guide port exposes the skin, pull out two sutures (blue and white), pass the blue line through the knot pusher to tie a neck tight knot, and tighten the white line at the same time, and then use the knot pusher to tighten the two knots for about 30 seconds, relax the sutures and the knot pusher, determine whether there is bleeding in the wound, cut the sutures under the skin, and then cover it with gauze.
[0003] Since vascular suturing is a delicate operation, the vascular suture device needs to maintain a stable shape. The current usage method is for the doctor to hold the suture device in hand throughout the process. Therefore, the suturing process is more dependent on the doctor's experience and physical strength. Therefore, during the vascular suturing process, the stability and accuracy of the suture device cannot be fully guaranteed, which in turn affects the quality of the suture operation. Summary of the invention
[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a vascular suture fixation device to solve the problem that the prior art completely relies on the manual operation and experience of the doctor, and thus cannot fully guarantee the accuracy and convenience during the operation.
[0005] The technical solution adopted by the present invention is as follows: The present invention provides a vascular suture fixing device, comprising:
[0006] Connect the base and fix it to support the whole and keep it stable;
[0007] The suspension balance mechanism is arranged on the connection base and is used to control the stability of the vascular suture device so that the device can maintain stability and positioning effect only through the suspension balance mechanism without external force applied by the staff;
[0008] A multi-dimensional stabilizer, provided on the hovering balance mechanism, is used to maintain the angle and position of the vascular suture device;
[0009] Vascular staplers, devices used to sew up blood vessels;
[0010] The hovering balancing mechanism includes a control shell, in which a balancing mechanism is arranged, and the balancing mechanism includes a driving gear, a linkage gear, a counterweight, a balancing spring, a first linkage rod and a second linkage rod. A vertically arranged slide groove is arranged in the control shell, and the counterweight is slidably arranged in the slide groove. The driving gear and the linkage gear are rotatably arranged in the control shell and are located above the slide groove. The driving gear and the linkage gear are meshed with each other. The first linkage rod is fixed on the linkage gear, and the second linkage rod is hinged on the counterweight. The first linkage rod and the second linkage rod are hinged. The top of the balancing spring is fixed in the control shell, and the bottom of the balancing spring is connected to the counterweight. A hovering extension rod is rotatably arranged on the control shell, and the hovering extension rod is coaxial with the driving gear.
[0011] When the hovering extension rod is rotated, the driving gear is driven to rotate, which in turn drives the linkage gear to rotate, and then pushes the counterweight to slide through the first linkage rod and the second linkage rod, and the counterweight stretches the balance spring. Since the counterweight has a downward force under the action of gravity, and the balance spring has a force to pull the counterweight upward, the two forces maintain balance. Therefore, after the hovering extension rod is rotated, under the action of the balancing mechanism, the hovering extension rod can immediately and automatically maintain balance and keep hovering in the air without falling, thereby achieving a hovering effect.
[0012] Further, the multi-dimensional stabilizer includes a first adjustment end, a second adjustment end, a third adjustment end, a first adjustment rod, a second adjustment rod and a stabilizing end, the first adjustment rod has two ends connected to the first adjustment end and the second adjustment end, the second adjustment rod has two ends connected to the second adjustment end and the third adjustment end, the first adjustment rod and the second adjustment rod are tilting rods, the first adjustment rod is rotatably arranged relative to the first adjustment end, the second adjustment rod is rotatably arranged relative to the second adjustment end, and the stabilizing end is rotatably arranged relative to the third adjustment end;
[0013] The first adjustment end, the second adjustment end, and the third adjustment end are each provided with a micro brushless motor;
[0014] The stabilizing end is provided with a gyroscope, an acceleration sensor and a magnetometer, and a microcontroller connected thereto. The microcontroller controls a connected micro brushless motor. The acceleration sensor detects the gravity direction of the stabilizing end, the gyroscope detects the tilt angle direction of the stabilizing end, and the magnetometer assists the gyroscope in balancing according to the magnetic field strength. The brushless motor is then controlled by the microcontroller to drive the first adjusting end, the second adjusting end and the third adjusting end to rotate and adjust, so that the stabilizing end always remains horizontal.
[0015] Furthermore, a positioning frame is rotatably provided on the stabilizing end, and the vascular suture device rotates on the positioning frame.
[0016] Furthermore, the hovering balancing mechanism and the connecting base are arranged to rotate relative to each other.
[0017] Furthermore, the rotation plane of the positioning frame, the rotation plane of the vascular suturing device, and the rotation plane of the suspension balance mechanism are three different planes, and the three planes are perpendicular to each other.
[0018] Furthermore, the rotation planes where the first adjustment end, the second adjustment end, and the third adjustment end are located are different rotation planes, and the rotation planes where the first adjustment end and the third adjustment end are located are perpendicular to each other.
[0019] Furthermore, the fixing point of the upper end of the balance spring is located higher than the first linkage rod.
[0020] Furthermore, the connecting base includes a fixed plate, a clamping plate and a clamping screw. The fixed plate is provided with a hollow slide groove. Two clamping plates are arranged and are slidably arranged on both sides of the hollow slide groove. The clamping screw is rotatably arranged on the fixed plate. The clamping screw and the two clamping plates are threadedly connected. The clamping screw is a bidirectional screw with threads at both ends in opposite directions. A clamping knob is provided on the clamping screw, and then by rotating the clamping knob, the clamping screw is driven to rotate, and then the two clamping plates are driven to move relative to each other, generating a clamping motion, so that the overall mechanism is clamped and fixed on the bed or other fixed body.
[0021] Furthermore, a rotation damper is connected to the rotation axis of the positioning frame, the rotation axis of the vascular suturing device, and the axis of the suspension balance mechanism to keep them in position after rotation.
[0022] The beneficial effects achieved by the present invention using the above structure are as follows: This scheme provides a vascular suture device fixing device, through the setting of the balance mechanism in the hovering balance mechanism, when the hovering extension rod is rotated, a balance is generated between the tension of the spring and the gravity, so that the hovering extension rod can immediately and automatically maintain balance and keep hovering in the air without falling, thereby achieving a hovering effect; through the setting of the multi-dimensional stabilizer, the stabilizing end can automatically complete the horizontal adjustment regardless of any direction and position adjustment, so that the stabilizing end always remains horizontal, and then the above effect is applied to the vascular suture device, so that the vascular suture device can maintain the hovering function, and then maintain a stable position when losing human control, thereby freeing the doctor's hands in a short time, and after the vascular suture device is adjusted, it can always maintain a stable state, thereby improving the precision of the operation.
