Description

Technical Field

[0001] The present invention relates to the technical field of pancreatic resection surgery, and specifically to a hemostatic device in pancreatic resection surgery. Background Art

[0002] Pancreatic resection surgery medically refers to the surgical removal of all or part of the pancreas, which is an important means of treating pancreatic diseases.

[0003] In pancreatic resection surgery, due to the rich blood vessels around the pancreas, bleeding may occur during the operation. To achieve the purpose of pancreatic hemostasis, doctors use hemostatic forceps to clamp the bleeding blood vessels. This method can quickly and effectively control bleeding and ensure the smooth progress of the operation.

[0004] After the traditional hemostatic forceps clamp the blood vessels for hemostasis, the clamping angle and force of the hemostatic forceps handle are fixed through the locking structure on the hemostatic forceps. When loosening the forceps, any one of the forceps handles needs to be pushed so that the tooth blocks on the locking structure are no longer engaged, thus achieving the purpose of loosening the forceps.

[0005] However, when pushing any one of the forceps handles, since the forceps handle and the forceps beak are fixed, when the forceps handle is pushed, the forceps beak will also move accordingly. At this time, the forceps beak is clamping the blood vessel, and the movement of the forceps beak will play a pulling role on the clamped blood vessel, and the blood vessel may be damaged and ruptured when being pulled, endangering the life safety of the patient. Moreover, because the sizes and thicknesses of blood vessels are different, when the surgeon clamps the blood vessel with the hemostatic forceps again, since the hemostatic forceps is not provided with a force adjustment structure, it may cause the clamping force of the hemostatic forceps to be too large, resulting in the possibility of blood vessel damage;

[0006] Therefore, a hemostatic device in pancreatic resection surgery is provided to solve the problems raised in the above background art. Summary of the Invention

[0033] Please refer to Figures 1 to 7 : A hemostatic device in a pancreatic resection operation, including a hemostatic forceps 1. The hemostatic forceps 1 includes a left handle 101 and a right handle 102 that are hinged to each other; when the left handle 101 and the right handle 102 approach each other, the blood vessels at the site to be hemostatic can be clamped by the beaks on the left handle 101 and the right handle 102, thereby playing a role in hemostasis during pancreatic surgery.

[0034] A locking structure is provided on the left handle 101 and the right handle 102. The locking structure includes a left grip 103 and a right grip 104. One end of the right grip 104 is fixedly connected to a connecting handle 2. The left grip 103 is fixedly connected to the left handle 101. Two turning rods 201 are fixedly connected to both sides of the connecting handle 2. The turning rods 201 are rotatably connected to the right handle 102. A torsion spring is sleeved on the turning rods 201. The locking structure can lock the left handle 101 and the right handle 102. Locking blocks 203 are fixedly connected to the adjacent sides of the left grip 103 and the right grip 104. The two groups of locking blocks 203 are symmetrically arranged. A plurality of meshing teeth 204 are fixedly connected to the adjacent sides of the two groups of locking blocks 203.

[0035] Among them, when the beaks on the left handle 101 and the right handle 102 clamp the blood vessels at the site to be hemostatic, the locking blocks 203 on the left handle 101 and the right handle 102 will approach each other, and the locking blocks 203 on the left handle 101 and the right handle 102 are arranged at different heights. When the two locking blocks 203 approach and contact, the teeth 204 on the locking blocks 203 will contact and mesh. When the teeth 204 on the two groups of locking blocks 203 are in contact, they will deform, and after deformation, they will be engaged with each other. Without external force, the left handle 101 and the right handle 102 will no longer separate, thereby playing a role in fixing the positions of the beaks on the left handle 101 and the right handle 102, so as to clamp the blood vessels and prevent the blood inside the blood vessels from flowing.

[0036] Furthermore, when it is necessary to relax the blood vessels, the finger (usually the thumb) holding the right handle 102 pushes the right grip 104 upward (to Figure 1(taking the right grip 104 moving upward as the reference direction), when the right grip 104 moves upward, it will drive the connecting handle 2 to deflect at an angle through the inside of the right jaw 102 via the flipping rod 201. Since the connecting handle 2 is not fixedly connected to the right jaw 102, when the right grip 104 moves, it will not drive the right jaw 102 to move, thus not driving the forceps beak to move and not pulling on the clamped blood vessel, thereby playing a protective role for the blood vessel; when the right grip 104 moves upward, the locking blocks 203 on the left grip 103 and the right grip 104 will also displace, and then the teeth 204 on the two groups of locking blocks 203 will no longer engage with each other, making the left grip 103 and the right grip 104 no longer locked, thereby playing a role in relaxing the blood vessel.

[0037] Preferably, the distance between multiple teeth 204 is maintained within the range of 0.1 - 0.5 mm.

[0038] Among them, the distance between the teeth 204 can control the distance between the two forceps beaks. The shorter the distance between multiple teeth 204, the more accurately the clamping force of the forceps beak on the blood vessel can be adjusted.

[0039] Inside the right jaw 102, a force adjustment structure is provided. The force adjustment structure can adjust the clamping force between the left jaw 101 and the right jaw 102. The force adjustment structure includes a cavity provided inside the right jaw 102. Inside the cavity, a fixed gear 304 is rotatably connected. On one side of the fixed gear 304, a transmission rod 303 is fixedly connected. One end of the transmission rod 303 is fixedly connected to a threaded lead screw 307. At the connection between the threaded lead screw 307 and the transmission rod 303, a rotating gear 305 is fixedly connected. Inside the cavity, a limiting rod 308 passes through and is slidably connected. The limiting rod 308 is threadedly connected to the threaded lead screw 307.

[0040] Among them, the principle of the above force adjustment is to make the limit distance between the forceps beaks on the left jaw 101 and the right jaw 102 adjustable. The specific principle is as follows: when the left jaw 101 and the right jaw 102 are in contact with each other, the forceps beaks will close. The provided limiting rod 308 will limit the left jaw 101, making the left jaw 101 unable to fully contact the right jaw 102, resulting in the forceps beaks on the left jaw 101 and the right jaw 102 not being able to fully contact either, and keeping a certain distance between the forceps beaks on the left jaw 101 and the right jaw 102. The setting of this distance is to prevent the hemostatic forceps from applying too much force when clamping a blood vessel with a thin wall, causing damage to the thin blood vessel.

[0041] Preferably, a cover plate is bolted to the cavity. The bottom side wall of the cover plate is slidably connected with a sliding plate 301. At the bottom side of the sliding plate 301, multiple elastic metal blocks 302 are fixedly connected. The multiple elastic metal blocks 302 are engaged with the rotating gear 305. One end of the sliding plate 301 is fixedly connected to the right jaw 102 with a fixed spring 306, and the other end of the sliding plate 301 is fixedly connected to the connecting handle 2 with a steel wire rope 3.

[0042] Among them, when force adjustment is required, first separate the left pliers handle 101 and the right pliers handle 102 so that the left pliers handle 101 and the right pliers handle 102 are not adjacent to each other and not in a fitting state, and the two groups of locking blocks 203 do not contact. Then refer to Figure 1 , press the right grip 104 reciprocally with the thumb. When the right grip 104 moves downward, it will drive the connecting rod 2 to deflect at an angle through the flipping rod 201;

[0043] As Figure 3 shown, the flipping rod 201 drives the connecting rod 2 to deflect clockwise. When the connecting rod 2 rotates, it will drive the sliding plate 301 to move through the steel wire rope 3. When the sliding plate 301 moves, it will make the elastic metal block 302 engage with the tooth block on the rotating gear 305, thereby driving the rotating gear 305 to rotate. When the rotating gear 305 rotates, it will drive the threaded lead screw 307 to rotate. When the threaded lead screw 307 rotates, it will make the limiting rod 308 move on the threaded lead screw 307, and the moving direction is close to the left pliers handle 101, so that the limiting rod 308 will play a role in limiting the left pliers handle 101, making the left pliers handle 101 unable to fully fit the right pliers handle 102, and completing the adjustment of the force.

[0044] Specifically, when the connecting rod 2 is not subjected to the up and down pressing force, under the action of the flipping rod 201 and the torsion spring, the connecting rod 2 remains in a flush state with the right pliers handle 102, and both sides of the connecting rod 2 are in contact with the right pliers handle 102, so that when the connecting rod 2 drives the right pliers handle 102 to contact the left pliers handle 101, it can be evenly stressed and will not produce a state of moving offset.

[0045] Furthermore, when the connecting rod 2 is not subjected to the up and down pressing force, under the pulling action of the fixed spring 306, the sliding plate 301 is located on the left side of the rotating gear 305, and the elastic metal block 302 on the sliding plate 301 is in a non-contact state with the tooth block on the rotating gear 305, avoiding the movement of the limiting rod 308 caused by accidental touch.

[0046] Preferably, a ratchet structure 4 is provided on one side of the fixed gear 304. The ratchet structure 4 includes a chute 401, the chute 401 is opened inside the cavity of the right pliers handle 102, a sliding block 402 is slidably connected inside the chute 401, a clamping block 403 is hinged on the sliding block 402, a limiting block 404 is provided on the lower side of the clamping block 403, and the limiting block 404 is fixedly connected with the sliding block 402.

[0047] Among them, the setting of the above ratchet structure 4 is to ensure that the fixed gear 304 can only rotate in one direction under the drive of the elastic metal block 302 on the sliding plate 301.

[0048] Specifically, when the right grip 104 is reciprocally pressed downwards to cause the connecting handle 2 to reciprocally rotate, as shown above, when the connecting handle 2 rotates clockwise, it will drive the sliding plate 301 to move through the steel wire rope 3; when the connecting handle 2 is reset under the action of the torsion spring and the fixed spring 306 drives the sliding plate 301 to move leftwards under the elastic action, the elastic metal block 302 will be in contact with the rotating gear 305. At this time, the rotating gear 305 rotates in the same direction as and is fixed to the fixed gear 304, and the fixed gear 304 cannot rotate counterclockwise under the action of the ratchet structure 4. Consequently, the rotating gear 305 cannot rotate counterclockwise either. Thus, when the leftward-moving sliding plate 301 moves, the elastic metal block 302 will be deformed and bent under the action of the teeth of the rotating gear 305 and will not drive the rotating gear 305 to rotate; repeating this process can enable the limiting rod 308 to always move towards the left clamping handle 101 direction.

[0049] Preferably, the chute 401 penetrates through the right clamping handle 102. A return spring 405 is fixedly connected inside the chute 401, and the return spring 405 is fixedly connected to the sliding block 402. A spiral spring is provided at the connection of the fixed gear 304 and the inner cavity of the right clamping handle 102.

[0050] Among them, the principle of the ratchet structure 4 is as follows: One end of the latch 403 is inserted into the teeth of the fixed gear 304. When the fixed gear 304 rotates clockwise, the fixed gear 304 drives the latch 403 to deflect by a certain angle, and the latch 403 does not limit the teeth of the fixed gear 304, enabling the fixed gear 304 to rotate normally.

[0051] When the fixed gear 304 rotates counterclockwise, the latch 403 will limit the teeth of the fixed gear 304 through the set limit block 404, making the fixed gear 304 unable to rotate, thus completing the step of restricting the rotation direction of the fixed gear 304.

[0052] Specifically, when the limiting rod 308 needs to be reset, that is, the limiting rod 308 returns to the initial state and no longer limits the left clamping handle 101; it is only necessary to move the sliding block 402 leftwards, so that the latch 403 no longer limits the fixed gear 304. The fixed gear 304 will then return to the initial angle under the action of the spiral spring. When returning to the initial angle, the fixed gear 304 drives the threaded lead screw 307 to rotate counterclockwise. When the threaded lead screw 307 rotates counterclockwise, it will cause the limiting rod 308 to move towards the right clamping handle 102 direction, enabling the limiting rod 308 to no longer limit the left clamping handle 101.

[0053] Among them, the chute 401 is a through setting, that is, the sliding block 402 can also be toggled to move on the right side of the right clamping handle 102, that is, outside the cavity.

[0054] Preferably, the cross-section of the limiting rod 308 is rectangular and is slidably connected to the inner wall of the right pliers handle 102. The contact surface of the limiting rod 308 with the left pliers handle 101 is flush. The two locking blocks 203 are integrally arc-shaped and fit perfectly when they are in contact with each other.

[0055] Among them, when the threaded lead screw 307 drives the rectangular limiting rod 308 to slide inside the right pliers handle 102, there will be no angular deflection. The two arc-shaped locking blocks 203 can fit perfectly when the right grip 104 and the left grip 103 make a circular motion and close, so that the tooth blocks 204 on the two locking blocks 203 are more closely matched.

[0056] Working principle: When it is necessary to relax the blood vessel, the finger holding the right pliers handle 102 pushes the right grip 104 upward. When the right grip 104 moves upward, it will drive the connecting rod 2 to deflect at an angle inside the right pliers handle 102 through the turning rod 201. Since the connecting rod 2 is not fixedly connected to the right pliers handle 102, when the right grip 104 moves, it will not drive the right pliers handle 102 to move, and thus will not drive the pliers beak to move, and will not pull the clamped blood vessel, thereby playing a protective role for the blood vessel; when the right grip 104 moves upward, the locking blocks 203 on the left grip 103 and the right grip 104 will also move, so that the tooth blocks 204 on the two locking blocks 203 no longer engage with each other, and the left grip 103 and the right grip 104 are no longer locked, thus playing a role in relaxing the blood vessel; when the right grip 104 is repeatedly pressed downward to make the connecting rod 2 rotate reciprocally, as shown above, when the connecting rod 2 rotates clockwise, it will drive the sliding plate 301 to move through the steel wire rope 3; when the connecting rod 2 returns to its original position under the action of the torsion spring, and the fixed spring 306 drives the sliding plate 301 to move leftward under the elastic action, the elastic metal block 302 will be in contact with the rotating gear 305. At this time, the rotating gear 305 rotates in the same direction as the fixed gear 304 and is fixed. However, due to the ratchet structure 4, the fixed gear 304 cannot rotate counterclockwise, and thus the rotating gear 305 cannot rotate counterclockwise either. Therefore, when the leftward moving sliding plate 301 moves, the elastic metal block 302 will be deformed and bent under the action of the tooth blocks of the rotating gear 305 and will not drive the rotating gear 305 to rotate; repeating this process, the limiting rod 308 can always move towards the left pliers handle 101.

[0057] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
