[0002] In the medical field, bleeding is a common complication during endoscopic examinations and treatments. Timely and effective hemostasis is crucial for ensuring patient safety and the smooth progress of treatment. Endoscopic hemostatic clips, which cause minimal damage to the mucosa around the wound, are currently widely used for mechanical hemostasis.

[0003] Publication number CN220001852U discloses an endoscopic hemostatic clip device. However, the above-mentioned prior art requires medical staff to hold the cannula with one hand and insert it into the wound. When hemostasis is required, the other hand is needed to pull the pull rope. This means that medical staff need to use both hands to complete the operation. However, two-handed operation requires more space. In the small surgical space, the two hands may interfere with each other, affecting the smoothness of the operation. Moreover, two-handed operation may not be able to adjust the surgical field in time, resulting in obstruction of the field of vision. For some obese patients or patients with more complex thoracic structures, the surgical space is even smaller, which has great limitations in actual use. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6The present invention provides a technical solution: a handheld endoscopic hemostasis device for cardiothoracic surgery, comprising a handle 1, a sleeve 2 provided on the front side of the handle 1, a viewing probe 3 for real-time acquisition of images of the bleeding site provided on the front side of the sleeve 2, two connecting plates 4 fixedly connected to the surface of the sleeve 2, two connecting blocks 5 fixedly connected to the end of the connecting plate 4 away from the handle 1, a hemostatic clip 6 for clamping the bleeding site provided between the two connecting blocks 5, a first cavity 7 opened inside the handle 1, a through groove 8 extending outwards opened on the surface of the first cavity 7, and an anti-slip knob 9 for easy operation by medical personnel provided inside the through groove 8.

[0027] The anti-slip knob 9 is rotatably connected to the inside of the first cavity 7 via a shaft. The surface of the anti-slip knob 9 is fixedly connected with teeth 10. Rotating the anti-slip knob 9 will drive the teeth 10 to move. The inside of the first cavity 7 is provided with a support rod 12 that provides support. The right end of the support rod 12 is rotatably connected to the inner wall of the first cavity 7. The surface of the support rod 12 is fixedly fitted with a gear 11. The gear 11 and the teeth 10 are meshed. When the anti-slip knob 9 is rotated, it will drive the gear 11 to rotate. The rotation of the gear 11 will drive the support rod 12 to rotate. The outside of the support rod 12 is provided with a drive assembly.

[0028] Among them, the endoscopic probe 3 is an existing structure. By inserting the endoscopic probe 3 into the human body, doctors can directly observe the specific location of bleeding, the speed of bleeding, the shape and size of the bleeding foci, and the condition of surrounding tissues, so as to accurately judge the condition and provide precise location information for subsequent hemostasis operations. Its specific principle will not be described in detail in the plan.

[0029] The drive assembly includes a pull rope 13 that serves as a connection. The pull rope 13 is fixedly sleeved on the outside of the support rod 12. The pull rope 13 can be wound up by rotating the support rod 12. The pull rope 13 slides through the handle 1 and the interior of the connecting plate 4 in sequence. A rotating rod 14 that serves as a connection is rotatably connected between the two connecting blocks 5. The hemostatic clip 6 is fixedly sleeved on the outer surface of the rotating rod 14. The rotation of the rotating rod 14 can drive the rotation of the hemostatic clip 6.

[0030] One end of the pull rope 13 located outside the connecting plate 4 is fixedly connected to the rotating rod 14. The rotating rod 14 can be rotated by moving the pull rope 13.

[0031] The connecting block 5 has a second cavity 15 inside. Both ends of the rotating rod 14 are rotatably inserted into the interior of the second cavity 15. A torsion spring 16 for resetting the rotating rod 14 is fixedly connected to the inner wall of the second cavity 15. The torsion spring 16 is movably sleeved on the outside of the rotating rod 14 and fixedly connected to the rotating rod 14.

[0032] The inner wall of the first cavity 7 is provided with a groove 17. The pull rope 13 slides through the groove 17 and passes through the inside of the handle 1. The inside of the groove 17 is connected to two pulleys 18 by a shaft. The pull rope 13 is located between the two pulleys 18. The setting of the pulleys 18 effectively reduces the friction generated when the pull rope 13 slides inside the handle 1, thereby effectively reducing the wear of the pull rope 13 and extending the service life of the pull rope 13.

[0033] The handle 1 is provided with a locking rod 19 on the outside for easy gripping by medical staff. The locking rod 19 slides through the interior of the first cavity 7. The side surface of the locking rod 19 facing the support rod 12 has a sliding groove 20 to restrict the movement trajectory of the structure. The sliding groove 20 is slidably connected to a sliding tooth 21. By pulling the locking rod 19 outward, the locking rod 19 will drive the sliding tooth 21 to move, thereby separating the sliding tooth 21 from the fixed tooth 22. The anti-slip knob 9 can then be operated again to reset the pull rope 13.

[0034] A first spring 23 for resetting the sliding tooth 21 is fixedly connected between the inner wall of the sliding tooth 21 and the sliding groove 20. When the support rod 12 rotates, it will drive the fixed tooth 22 to rotate. At this time, the inclined surface of the fixed tooth 22 will abut against the inclined surface of the sliding tooth 21, thereby pushing the sliding tooth 21 to slide inside the sliding groove 20. At this time, the first spring 23 will retract. A second spring 24 is movably sleeved on the outside of the locking rod 19. The end of the second spring 24 near the handle 1 is fixedly connected to the handle 1.

[0035] The left end face of the support rod 12 is fixedly connected with a fixed locking tooth 22, which is compatible with the sliding locking tooth 21.

[0036] In the above embodiment, an injection tube extending from the front end of the sleeve 2 can be provided inside the sleeve 2, and the injection tube extends into the first cavity 7. Subsequently, the injection tube will extend from the first cavity 7 out of the handle 1, so that the medicine can be sprayed through the setting of the injection tube. This is the prior art, and the specific details can be found in the prior art with publication number CN220001852U. Since it is not the main structure, it is not described or shown in the solution.

[0037] Working principle:

[0038] When using this handheld endoscopic hemostasis device for cardiothoracic surgery, medical staff insert the cannula 2 into the wound and use the endoscopic probe 3 to view the bleeding location, thus achieving the purpose of bedside hemostasis. When hemostasis is needed, the anti-slip knob 9 is turned by the finger. The rotation of the anti-slip knob 9 moves the teeth 10. Since the teeth 10 and gear 11 are meshed, the rotation of the anti-slip knob 9 will drive the gear 11 to rotate. The rotation of the gear 11 will drive the support rod 12 to rotate. The rotation of the support rod 12 will retract the pull rope 13. At this time, the pull rope 13 will slide inside the handle 1 and the connecting plate 4. The movement of the pull rope 13 will cause the rotating rod 14 to rotate. The rotation of the rotating rod 14 will drive the rotation of the hemostatic clamp 6, ultimately clamping the blood vessel at the bleeding site, thus achieving the purpose of simultaneous hemostasis at the bedside.

[0039] Furthermore, when the support rod 12 rotates, it will drive the fixed locking tooth 22 to rotate. At this time, the inclined surface of the fixed locking tooth 22 will abut against the inclined surface of the sliding locking tooth 21, thereby pushing the sliding locking tooth 21 to slide inside the sliding groove 20. At this time, the first spring 23 will contract. After the hemostatic clip 6 is clamped, the anti-slip knob 9 is released. At this time, the vertical surfaces of the fixed locking tooth 22 and the sliding locking tooth 21 will abut against each other, so that the support rod 12 will not rotate, thereby locking the hemostatic clip 6.

[0040] When the rotating rod 14 rotates, it will cause the torsion spring 16 to deform, which will facilitate the subsequent reset of the rotating rod 14.

[0041] After the bleeding has been stopped, pull the locking lever 19 outward. The locking lever 19 will move the sliding tooth 21, which will separate the sliding tooth 21 from the fixed tooth 22. Then, the anti-slip knob 9 can be operated again to reset the pull rope 13.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
