[0002] Since patients will bleed during surgery, excessive bleeding will seriously affect the patient's life and health. In order to reduce the amount of bleeding, the wound needs to be sealed in time after the operation. At present, sealing of large-caliber wounds requires the use of multiple instruments. The sealing is difficult and the entire sealing process is time-consuming. Bleeding will still occur during the sealing process, increasing the patient's postoperative risk. After the operation, the number of sealing instruments may need to be adjusted according to the different sizes of the wounds. The sealing is more complicated and difficult, and will increase the amount of bleeding to a certain extent. Therefore, the existing sealing technology needs to be improved. Summary of the invention

By improving and optimizing the structure of the sealing system, an integrated transmission feedback mechanism is set up. When the suture is pulled during operation, the pressure tube will move downward, pushing the sealing assembly downward, thereby realizing automatic sealing of the vascular wound, improving the sealing speed and reducing blood loss.

[0004] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides a vascular wound occlusion system, comprising: a delivery sheath assembly, a delivery tube, a pressure delivery tube, a guide wire guide tube, an occlusion assembly and a handle mechanism, wherein the delivery sheath assembly, the delivery tube and the pressure delivery tube are arranged in sequence from the outside to the inside, one end of the guide wire guide tube is arranged in the pressure delivery tube, the occlusion assembly is arranged in the delivery tube and at one end of the pressure delivery tube away from the handle mechanism, and is connected to the suture, the delivery sheath assembly comprises a sheath tube, the sheath tube is connected to the handle mechanism through a transmission connection assembly, and an integrated transmission feedback mechanism is arranged in the handle mechanism;

[0005] Also included is a dilator, which cooperates with the sheath;

[0006] The integrated transmission feedback mechanism includes a transmission gear, a suture gear for binding sutures, and a control key. The rack section on the pressure tube meshes with the transmission gear. A group of elastic parts are arranged on the upper part of the transmission gear. The suture gear is arranged above the transmission gear, and the two cooperate with each other. The downward pressure column at the bottom of the control key cooperates with the elastic part. Pressing the control key causes the elastic part to deform and disengage from the suture gear, so that the transmission gear no longer runs synchronously with the suture gear. The handle is moved to cut the suture. The vascular wound occlusion system described in the present invention improves and optimizes the structure of the occlusion system and is provided with an integrated transmission feedback mechanism. When the suture is pulled during operation, the pressure tube moves downward, pushing the occlusion assembly downward, realizing automatic occlusion of the vascular wound, improving the occlusion speed, and reducing blood loss.

[0007] The control key includes a pressing member and a pressing column, the pressing member is L-shaped, the pressing column is arranged below the pressing member, and the upper surface of the pressing member is inclined. The pressing member surface is arranged in an inclined shape, and when the handle is rotated to reach a horizontal position, the angle between the handle and the patient is 45°, that is, the release angle, which means that the blocking component can be released for blocking, thereby ensuring the accuracy of its blocking release.

[0009] The integrated transmission feedback mechanism also includes a feedback component, which is arranged in the guide track of the inner wall of the handle housing, and one end of the feedback component is connected to the suture gear transmission. When the pressure tube moves downward, the feedback component moves backward to achieve integrated feedback. The arrival position of the feedback component can be clearly seen through the observation window, so that the size of the operator's pulling force can be reflected through the distance.

[0010] Furthermore, the elastic part includes an elastic part body, the outer side of the elastic part body is provided with teeth, the side away from the teeth is provided with a bending portion, the bending portion is provided with an upward protrusion, and the upward protrusion is located on a side of the inner wall of the lower pressure column and is provided with an inclined surface, the upward protrusion is arranged in the lower pressure column to realize the connection between the transmission gear and the control key.

[0011] Furthermore, the suture gear includes a gear plate, a winding portion is provided above the gear plate, a gear is provided above the winding portion, and a group of tooth grooves are provided on the inner wall of the gear plate, and the tooth grooves cooperate with the teeth; in the initial state, the upper part of the elastic member is arranged in the gear plate, the teeth are located in the tooth grooves, and the transmission gear and the suture gear rotate synchronously; after pressing the control key, the pressure column presses down the elastic member, the elastic member is deformed, and the teeth are separated from the tooth grooves. After separation, the transmission gear no longer operates synchronously with the suture gear, and the handle is moved to cut the suture.

[0012] Preferably, the feedback assembly includes a feedback rack and a feedback identification block, the feedback rack is arranged in the guide track, the two are movably connected, one end of the feedback rack is meshed with the gear of the suture gear, the feedback identification block is arranged at the end of the feedback rack away from the suture gear, and a scale is provided on the feedback identification block. The scale on the feedback identification block can intuitively show the distance the feedback rack moves.

[0013] Further preferably, the pressure delivery pipe includes a pipe section and a rack section, one end of the delivery pipe located in the handle housing is fixed by a pipe fixing piece, a guide wire hole and a suture hole are provided in the pipe section, and a scale is provided on the pipe section, the guide wire guide tube is provided in the guide wire hole, the rack section is provided at one end of the pipe section away from the plugging assembly, and a trumpet-shaped flare is provided at one end of the pipe section away from the rack section. The rack section drives the pipe section to move during the rotation of the transmission gear, and the rack section drives the pipe section to move, thereby driving the plugging assembly to move downward to achieve plugging; at the same time, the trumpet-shaped flare can ensure that the plugging assembly is pushed and clamped.

[0014] The transmission connection assembly of the present invention comprises a release bolt and a release nut. The outer side of the release bolt is provided with a thread, and a group of bumps are provided at one end of the release bolt close to the sheath tube. The housing of the release nut is threadedly connected to the release bolt, and the end of the release nut away from the bumps is connected to the handle housing.

[0015] The protrusion is provided with a first inclined surface, the sheath tube connection buckle on the sheath tube is engaged with the protrusion, the contact surface between the buckle and the protrusion is an inclined surface, and the inclined surface matches the first inclined surface. The release bolt and the release nut cooperate to rotate the release nut as needed to drive the handle assembly and move, thereby realizing the movement of the delivery tube and the sheath tube.

[0016] Preferably, the blocking assembly includes a blocking piece and a sealing member, a connecting column is provided at the rear of the blocking piece, at least one group of positioning rods are provided around the connecting column, the sealing member is provided at the rear of the blocking piece, and a guide wire hole is provided on the connecting column, and the guide wire hole cooperates with the guide wire tube. With the arrangement of the connecting column and the positioning rod, after being pulled, the connecting column passes through the sealing member, and the positioning rod can fix and limit the sealing member to prevent it from loosening, thereby increasing the effect of wound sealing. In actual use, different sizes of blocking sheets can be replaced according to the size of the postoperative wound, so as to quickly achieve the sealing of vascular wounds of different sizes, reduce the replacement time of the device, and improve the sealing efficiency.

[0017] The present invention also includes a dilator, wherein the end of the dilator close to the handle mechanism is provided with a tail end blood flow marking port, the end away from the handle mechanism is provided with a head end blood flow marking port, and the dilator is matched with the sheath. The setting of the tail end blood flow marking port can reduce the exchange of instruments and ensure the release position.

[0018] The working method of the vascular wound occlusion system of the present invention is as follows: 1): first, the dilator is placed in the sheath, when the blood flow marking port at the head end of the dilator enters the blood vessel, blood will flow out of the blood flow marking port at the tail end, and then the dilator is withdrawn;

[0019] 2): The sheath tube and the handle mechanism are installed through the transmission connection assembly and are connected with the protrusion through the buckle, and the end of the delivery tube and the pressure delivery tube away from the handle mechanism is inserted into the sheath tube;

[0020] 3): After the delivery tube is fully inserted, rotate the release nut to allow the handle mechanism to drive the delivery tube to move backward, allowing the occluding piece in the occluding assembly to be released in the blood vessel;

[0021] 4): Adjust the indicator part at the tail of the handle mechanism. When the indicator part at the tail of the handle mechanism is horizontal, pull the handle mechanism backward to make the occluding piece fit the inner wall of the blood vessel. At this time, no blood will flow out of the sheath.

[0022] 5): Continue to pull the handle mechanism backward. Since one end of the suture and the occluding piece are located in the blood vessel, when the handle mechanism is pulled backward, the suture will pull the suture gear to rotate. When the suture gear rotates, it will drive the transmission gear to rotate together. Since the transmission gear is meshed with the rack segment, the rack segment will be driven to move during the transmission gear rotation, so that the pressure delivery tube continues to move toward the blood vessel end, and the seal is pressed down to the outside of the blood vessel wound. Continue to press down until the positioning rod is stuck to the seal to position it;

[0023] Since the gear on the suture gear is meshed with the feedback rack, the suture gear will drive the feedback rack to move horizontally, and the feedback identification block will be driven to move backwards during the movement of the feedback rack;

[0024] 6): Observe the feedback identification block through the observation window on the handle housing to obtain the downward pressure distance of the pressure delivery tube, and use the distance to reflect the size of the operator's pulling force;

[0025] 7): When the pulling distance reaches the position and the pulling force reaches the preset value, press the control key. After the pressure column presses down the elastic part, the elastic part deforms and the teeth disengage from the tooth grooves. After separation, the transmission gear no longer runs synchronously with the suture gear. Move the handle to cut the suture.

[0026] It can be seen from the above technical solution that the present invention has the following beneficial effects:

[0027] 1. The vascular wound sealing system described in the present invention improves and optimizes the structure of the sealing system and sets an integrated transmission feedback mechanism. When the suture is pulled during operation, the pressure tube will move downward to push the sealing component downward, so that the sealing sheet and the sealant can seal the vascular wound from both sides, thereby realizing automatic sealing of the vascular wound, effectively improving the sealing speed and reducing the patient's blood loss. During the sealing process, the feedback component in the integrated transmission feedback mechanism moves backward, and the arrival position of the feedback component can be clearly seen through the observation window, so that the size of the operator's pulling force can be reflected by the distance to ensure the accuracy of the release.

[0028] 2. In the present invention, the transmission gear rotates to drive the rack section to move, and the rack section drives the pipe section to move, thereby driving the plugging assembly to move downward to achieve plugging; at the same time, the trumpet-shaped expansion setting can ensure that the plugging assembly is pushed and clamped.

[0029] 3. The connection column and the positioning rod are arranged in the sealing assembly of the present invention. After being pulled, the connection column passes through the sealing member, and the positioning rod can fix and limit the sealing member to prevent it from loosening, thereby increasing the effect of wound sealing. In actual use, different sizes of sealing pieces can be replaced according to the size of the postoperative wound to quickly achieve the sealing of vascular wounds of different sizes, thereby reducing the number of sealing devices used and improving the sealing efficiency.

The feedback rack 4141 is arranged in the guide track 401, and the two are movably connected. One end of the feedback rack 4141 is meshed with the gear of the suture gear 412. The feedback identification block 4142 is arranged at the end of the feedback rack 4141 away from the suture gear 412, and a scale is provided on the feedback identification block 4142.

[0052] like Figure 5 The pressure delivery tube 3 shown includes a tube section 31 and a rack section 32.

The rack section 32 is provided at one end of the tube section 31 away from the blocking assembly 5, and a trumpet-shaped expansion is provided at one end of the tube section 31 away from the rack section 32.

[0053] like Figure 2 The transmission connection assembly 8 shown includes a release bolt 81 and a release nut 82. The release bolt 81 is provided with a thread on its outer side, and a group of protrusions 811 are provided at one end thereof close to the sheath tube 7.

[0056] The sheath tube 7 includes a sheath tube flushing tube 72. The sheath tube flushing tube 72 can be quickly flushed to ensure its cleanliness.

[0057] The dilator 9 has a tail end blood flow marking port 91 at one end close to the handle mechanism 6 , and a head end blood flow marking port 92 at one end away from the handle mechanism 6 .

[0058] The working method of the vascular wound sealing system is as follows: 1): first, the dilator 9 is placed in the sheath 7, when the blood flow marking port 92 at the head end of the dilator 9 enters the blood vessel, blood will flow out of the blood flow marking port 91 at the tail end, and the dilator 9 is then withdrawn;

[0059] 2): The sheath tube 7 and the handle mechanism 6 are installed through the transmission connection assembly 8, and are engaged with the protrusion 811 through the buckle 71, and the ends of the delivery tube 2 and the pressure delivery tube 3 away from the handle mechanism 6 are inserted into the sheath tube 7;

[0060] 3): After the delivery tube 2 is fully inserted, the release nut 82 is rotated to allow the handle mechanism 6 to drive the delivery tube 2 to move backward, so that the blocking piece 51 in the blocking assembly 5 is released in the blood vessel;

[0061] 4): Adjust the indicating part at the tail of the handle mechanism 6.

At this time, no blood flows out of the sheath tube 7;

[0062] 5): Continue to pull the handle mechanism 6 backward. Since one end of the suture and the occluding piece 51 are located in the blood vessel, when the handle mechanism 6 is continued to be pulled backward, the suture will pull the suture gear 412 to rotate. When the suture gear 412 rotates, it drives the transmission gear 411 to rotate together. Since the transmission gear 411 is meshed with the rack segment 32, the transmission gear 411 will drive the rack segment 32 to move during its rotation, so that the pressure delivery tube 3 continues to move toward the blood vessel end, and the sealing member 52 is pressed down to the outside of the blood vessel wound. The pressure is continued to be pressed down until the positioning rod 512 is stuck to the sealing member 52 to position it.

[0063] Since the gear on the suture gear 412 is meshed with the feedback rack 4141, the suture gear 412 drives the feedback rack 4141 to move horizontally, and the feedback rack 4141 drives the feedback identification block 4142 to move backwards during the movement;

[0064] 6): Observe the feedback identification block 4142 through the observation window on the handle housing to obtain the downward pressing distance of the pressure delivery tube 3, and reflect the pulling force of the operator through the distance;

[0065] 7): When the pulling distance reaches the position and the pulling force reaches the predetermined value, the control key 413 is pressed, and the pressing column 4132 presses down the elastic member 4111, and the elastic member 4111 is deformed, and the teeth 4112 are separated from the tooth grooves 4123. After separation, the transmission gear 411 no longer runs synchronously with the suture gear 412, and the handle is moved to cut the suture.

[0066] The above description is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
