Description

Technical Field

[0001] The present invention belongs to the technical field of medical instruments, and in particular relates to a hemostatic device for patients undergoing hepatobiliary and pancreatic surgery. Background Art

[0002] Hepatobiliary and pancreatic surgery is a treatment for diseases of the hepatobiliary and pancreatic system. It involves the resection or repair of organs such as the liver, gallbladder, and pancreas. It is divided into traditional open surgery and minimally invasive surgery. Traditional open surgery requires a large incision in the abdomen so that the doctor can directly observe and operate the surgical area; minimally invasive surgery includes laparoscopic surgery, percutaneous interventional therapy, radiofrequency ablation, endoscopic treatment, etc.

[0003] The existing publication number is CN110960316A, "A rapid hemostasis device for hepatobiliary surgery". This comparative document points out that the electrocoagulation hemostasis equipment and drug hemostasis tools used in clinical practice cannot be effectively combined, resulting in the inability to further improve the hemostasis speed and the lack of the ability to continuously provide hemostatic drugs to the sterile sponge. Then, this comparative document solves the above problems by setting up the coordination between the drug supply chamber structure and the electrocoagulation electrode structure, realizing the seamless combination of electrocoagulation hemostasis and drug hemostasis, avoiding the cumbersome steps of operating the two separately in the prior art, and providing the drug supply chamber structure to the sterile sponge during the hemostasis process. Automatically replenishing hemostatic drugs in the sterile sponge greatly improves the hemostatic efficiency and reduces the waste of hemostatic drugs. However, the comparative document has shortcomings in actual use. Since the sterile sponge adopts a fixed design, when the sterile sponge frequently contacts the bleeding point, the blood remaining on the outer surface of the sterile sponge will coagulate over time, thereby forming a layer of blood stains on the surface of the sterile sponge. At this time, the sterile sponge and the bleeding point will be blocked by this part of the coagulated blood, which will affect the contact between the sterile sponge and the bleeding point, and then affect the application of the hemostatic agent.

[0004] The existing publication number of CN114587566A is "A hemostatic device for postoperative wounds of hepatobiliary and pancreatic patients". This comparative document proposes that blood will adhere to the contact area on the sponge and quickly coagulate to block the small holes on the sponge, making it impossible for the hemostatic agent to flow out from the contact area, and thus the sponge cannot continue to be used to contact the bleeding point to stop bleeding. Then, this comparative document solves the above problem by setting a pressure rod structure and a rotating rod structure to cooperate with each other, so that the surgeon can maintain the same operating action to make different areas on the sterile sponge contact the bleeding point in turn. However, this comparative document has shortcomings in actual use. Since the electrocoagulation electrode is exposed and lacks corresponding protective mechanisms, the surgeon cannot properly place the hemostatic device during the operation due to time constraints. At this time, the exposed electrocoagulation electrode will easily collide with other surgical instruments, causing collision damage to the coagulation electrode. When the number of collisions is too many, the coagulation electrode will easily be damaged and needs to be replaced. Therefore, improvements are needed. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, an embodiment of the present invention provides a hemostatic device for hepatobiliary and pancreatic patients after surgery, comprising a handle 1, a fixed shell 2 is fixedly installed at the bottom end of the handle 1, a first circular shaft 3 is movably sleeved at the bottom of the right end of the fixed shell 2, a first arc plate 4 is fixedly installed at the left end of the first circular shaft 3, a second circular shaft 5 is movably sleeved at the bottom of the left end of the fixed shell 2, a second arc plate 6 is fixedly installed at the right end of the second circular shaft 5, a sterile sponge 7 is fixedly installed between the first arc plate 4 and the second arc plate 6, a support rod 8 is movably sleeved on the left side of the outer surface of the second circular shaft 5, and the support rod 8 is The right end is fixedly connected to the left end of the fixed shell 2, the left end of the outer surface of the second circular shaft 5 is fixedly sleeved with a gear 9, the right end of the gear 9 is movably connected to the left end of the support rod 8, the top of the outer surface of the gear 9 is movably connected with an insertion rod 10, the right end of the insertion rod 10 is movably connected to the left end of the support rod 8, the top of the inside of the insertion rod 10 is movably sleeved with a fixed block 11, the right end of the fixed block 11 is fixedly connected to the left end of the support rod 8, the bottom end of the fixed block 11 is fixedly installed with a first spring 12, and the other end of the first spring 12 is fixedly connected to the bottom of the inner surface of the insertion rod 10.

[0030] When the gear 9 is turned, the gear 9 will rotate with the sterile sponge 7, the first arc plate 4 and the first circular shaft 3 through the second circular shaft 5 and the second arc plate 6. As the gear 9 rotates, the rod 10 and the gear 9 are movably connected, so the rod 10 will be squeezed by the gear 9 and move upward along the outer surface of the fixed block 11 and compress the first spring 12. When the gear 9 stops rotating, the rod 10 will return to its original position under the recovery action of the first spring 12, so that the angle of the sterile sponge 7 can be adjusted, thereby preventing the outer surface of the sterile sponge 7 from sticking to the blood and affecting the contact between the medicine and the bleeding point. Among them, the bottom of the left end of the handle 1 is fixedly sleeved with a liquid infusion tube 13, the middle of the bottom end of the handle 1 is fixedly sleeved with a one-way valve 14, and the bottom end of the one-way valve 14 is fixedly installed with an infusion tube 15, and the bottom end of the infusion tube 15 is movably connected to the outer surface of the sterile sponge 7.

[0031] The presence of the infusion tube 13 facilitates the replenishment of the hemostatic agent, while the presence of the one-way valve 14 and the infusion tube 15 ensures that the hemostatic agent can be immersed in the sterile sponge 7 .

[0032] The top of the handle 1 is movably sleeved with a movable block 16 , the bottom of the movable block 16 is fixedly mounted with a piston 17 , and the outer surface of the piston 17 is movably sleeved with the inner surface of the handle 1 .

[0033] When the movable block 16 moves with the piston 17 , the medicine inside the handle 1 will penetrate into the sterile sponge 7 through the one-way valve 14 and the infusion tube 15 .

[0034] Among them, a fixing frame 18 is fixedly installed on the top of the handle 1, and a push block 19 is movably sleeved inside the fixing frame 18. The outer surface of the push block 19 is movably sleeved with the inner surface of the top of the handle 1, and the bottom end of the push block 19 is fixedly connected to the top of the movable block 16. A circular hole 20 is opened at the left end of the fixing frame 18, and a round rod 21 is movably sleeved inside the circular hole 20. The right side of the outer surface of the round rod 21 is movably sleeved with the inner surface of the push block 19.

[0035] When the push block 19 is pushed, the push block 19 will move with the movable block 16, and the round holes 20 are evenly arranged on the outer surface of the fixed frame 18. The positions of the movable block 16 and the push block 19 can be locked by fitting the round rod 21 with the round holes 20 at different positions.

[0036] Among them, the right end of the round rod 21 is fixedly connected with the second spring 22, and the other end of the second spring 22 is fixedly connected to the inner surface of the push block 19. A pressure block 23 is movably sleeved on the upper right inside the round rod 21. The top of the pressure block 23 penetrates the push block 19 and extends to the outside of the push block 19. The bottom end of the pressure block 23 is movably sleeved with a limit block 24, and the outer surface of the limit block 24 is fixedly sleeved with the inner surface of the push block 19.

[0037] When the pressing block 23 is pressed, the pressing block 23 moves along the outer surface of the limiting block 24 , so that the inclined surface at the bottom of the pressing block 23 squeezes the round rod 21 , and then the round rod 21 moves along the inner surface of the pushing block 19 and compresses the second spring 22 .

[0038] An electrocoagulation electrode 25 is fixedly mounted in the middle of the top of the handle 1 , and a protective shell 26 is movably sleeved on the top of the outer surface of the handle 1 .

[0039] Due to the presence of the electrocoagulation electrode 25 , electrocoagulation hemostasis is achieved, and the presence of the protective shell 26 can protect the electrocoagulation electrode 25 .

[0040] A first positioning hole 27 is formed at the top of the right side of the inner surface of the left end of the handle 1 , a second positioning hole 28 is formed at the bottom of the right side of the inner surface of the left end of the handle 1 , and a positioning block 29 is movably sleeved inside the second positioning hole 28 .

[0041] The first positioning hole 27 and the second positioning hole 28 have the same shape and size, so as to ensure that the positioning block 29 can be embedded in the first positioning hole 27 .

[0042] Among them, a rectangular block 30 is movably sleeved on the left side of the outer surface of the positioning block 29, the outer surface of the rectangular block 30 is movably sleeved on the inner surface of the left end of the handle 1, the outer surface of the rectangular block 30 is fixedly connected to the inner surface of the protective shell 26, and a long spring 31 is fixedly installed on the bottom end of the rectangular block 30, and the other end of the long spring 31 is fixedly connected to the bottom of the inner surface of the left end of the handle 1.

[0043] The long spring 31 is in a compressed state. When the positioning block 29 and the second positioning hole 28 are separated, the rectangular block 30 will move with the protective shell 26 under the restoring action of the long spring 31 .

[0044] Among them, a short spring 32 is fixedly installed on the left end of the positioning block 29, and the other end of the short spring 32 is fixedly connected to the inner surface of the protective shell 26. A long rod 33 is fixedly installed in the middle of the left end of the positioning block 29. The left end of the long rod 33 penetrates the protective shell 26 and extends to the outside of the protective shell 26 and is fixedly installed with a handle 34. The outer surface of the handle 34 is movably connected to the outer surface of the protective shell 26.

[0045] When the handle 34 is pulled, the handle 34 will move with the long rod 33 and the positioning block 29 and compress the short spring 32 , thereby separating the positioning block 29 and the second positioning hole 28 .

[0046] Working principle and usage process:

[0047] During use, the operator can achieve electrocoagulation hemostasis through the electrocoagulation electrode 25. After the use of the electrocoagulation electrode 25, the operator pulls the handle 34, so that the positioning block 29 moves along with the handle 34 through the long rod 33 and compresses the short spring 32 until the positioning block 29 and the second positioning hole 28 are separated. Because the long spring 31 is in a compressed state, the rectangular block 30 will move with the protective shell 26 under the recovery action of the long spring 31. When the positioning block 29 and the first positioning hole 27 are aligned, the operator releases the handle 34, so that the positioning block 29 is embedded in the first positioning hole 27 under the recovery action of the short spring 32, and then the position of the rectangular block 30 and the protective shell 26 is locked. In this way, the electrocoagulation electrode 25 can be protected with the help of the protective shell 26 to prevent it from being damaged by collision.

[0048] When local drug hemostasis is required, the operator presses the pressure block 23, so that the pressure block 23 moves along the outer surface of the limit block 24. At this time, the inclined surface at the bottom of the pressure block 23 will squeeze the round rod 21, so that the round rod 21 moves along the inner surface of the push block 19 and compresses the second spring 22 until the round rod 21 and the circular hole 20 are separated. Then the operator pushes the push block 19, so that the push block 19 moves with the piston 17 through the movable block 16, thereby immersing the hemostatic agent into the sterile sponge 7 through the one-way valve 14 and the infusion tube 15. After the sterile sponge 7 is soaked, the operator releases the pressure block 23. At this time, under the restoring action of the second spring 22, the round rod 21 will return to its original position and be embedded in the circular hole 20 at the corresponding position. Finally, the operator can stop the bleeding point through the sterile sponge 7. With the mutual cooperation of various mechanisms, the push block 19 can be effectively prevented from accidentally touching and moving.

[0049] When stopping bleeding at the next bleeding point, the operator turns the gear 9, so that the gear 9 rotates with the second arc plate 6, the sterile sponge 7, the first arc plate 4 and the first arc shaft 3 through the second circular shaft 5, and as the gear 9 rotates, the gear 9 will squeeze the insertion rod 10, so that the insertion rod 10 moves along the outer surface of the fixed block 11 and compresses the first spring 12. When the gear 9 stops being turned, the insertion rod 10 will return to its original position under the restoring action of the first spring 12 and the position of the gear 9 and the sterile sponge 7 will be re-locked. In this way, the angle of the sterile sponge 7 can be adjusted to prevent the outer surface of the sterile sponge 7 from sticking to the blood and affecting its contact with the bleeding point.
