Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a high-frequency surgical system. BACKGROUND

[0002] The high-frequency surgical system is an electrosurgical device which uses high-frequency current to replace mechanical surgical knives to cut tissues.

[0003] The existing high-frequency surgical system generally comprises a tissue closure device and a high-frequency surgical main machine. The tissue closure device is provided with an electrocoagulation forceps. One electrode of the high-frequency surgical main machine is electrically connected with the tissue closure device, and the other electrode is electrically connected with the body of a patient to be operated, so that the user only needs to clamp the tissue on the body of the patient to be operated by the electrocoagulation forceps, and then the high-frequency surgical main machine can generate high-frequency and high-voltage current between the electrocoagulation forceps and the tissue, so as to separate and coagulate the tissue on the body of the patient to be operated by the high-frequency and high-voltage current, thereby achieving the purpose of cutting and hemostasis.

[0004] However, since the high-frequency and high-voltage current on the electrocoagulation forceps needs to take a certain time to separate and coagulate the tissue, the user needs to hold the electrocoagulation forceps with force to keep the electrocoagulation forceps in a clamped state before the tissue is separated and coagulated, so that the use of the high-frequency surgical system is very inconvenient.

[0005] Therefore, it is necessary to provide a high-frequency surgical system. SUMMARY

[0006] In order to solve the problem that the existing high-frequency surgical system needs to be held with force by the user to keep the electrocoagulation forceps in a clamped state and is inconvenient to use, the present application provides a high-frequency surgical system.

[0007] The high-frequency surgical system provided by the present application adopts the following technical scheme: comprising a tissue closure assembly and a high-frequency main machine assembly, the tissue closure assembly comprises a mounting shell, a fixed sleeve, two scissor claws, a moving rod, a handle, a clamping handle and a self-locking unit, one end of the fixed sleeve is connected with the mounting shell, the two scissor claws are oppositely arranged on the other end of the fixed sleeve, and the middle part of each scissor claw is hingedly connected with the inner wall of the fixed sleeve, one end of each scissor claw is formed with a clamping part, and the other end of each scissor claw is located in the fixed sleeve and is in transmission connection with one end of the moving rod, the other end of the moving rod passes through the through hole formed in the mounting shell along the inner wall of the fixed sleeve and extends into the inside of the mounting shell, the handle is connected with the mounting shell, a hinge hole is formed in the shell between the handle and the fixed sleeve of the mounting shell, the middle part of the clamping handle is hingedly connected with the inner wall of the hinge hole, one end of the clamping handle extends away from the handle, and the other end of the clamping handle extends into the mounting shell and is connected with the moving rod. When the clamping handle is turned away from the handle towards the end of the moving rod, the moving rod can move towards the scissor jaws and drive the two clamping parts away from each other; The self-locking unit is arranged on the handle, and when the clamping handle is turned away from the handle towards the end of the moving rod, the moving rod moves away from the scissor jaws and drives the two clamping parts towards each other, and the self-locking unit can be connected with the clamping handle and limit the clamping handle away from the handle; The high-frequency main machine assembly can output high-frequency current to the scissor jaws.

[0008] By adopting the above technical scheme, when the tissue on the to-be-operated person needs to be processed, the user can first hold the handle to move the tissue closing assembly so that the tissue is located between the two clamping parts, and then use the fingers to pull the end of the clamping handle away from the moving rod towards the handle to make the clamping handle drive the moving rod to move away from the scissor jaws and drive the two clamping parts to move towards each other to clamp the tissue. At this time, the high-frequency main machine assembly outputs high-frequency current to the two scissor jaws, so that the tissue on the to-be-operated person can be separated and coagulated by using the high-frequency current, thereby achieving the purpose of cutting and hemostasis. The self-locking unit can be connected with the clamping handle and limit the end of the clamping handle away from the moving rod away from the handle, so that the user does not need to always keep the fingers tight to pull the clamping handle during the process of separating and coagulating the tissue by high-frequency current, thereby making the use of the high-frequency surgical system more convenient, and avoiding the situation that the tissue to be processed is separated from the two clamping parts due to the user's mistake of loosening the clamping handle, thereby causing the operation to fail.

[0010] By adopting the technical scheme, in the process that the user pulls the end of the clamping handle away from the moving rod toward the handle, the sliding block first abuts against the locking surface and slides along the locking surface, so that the end of the locking block away from the hinge shaft rotates toward the mounting shell, so that when the two clamping parts clamp the tissue, the sliding block can slide along the entire locking surface and bypass the end of the locking block away from the hinge shaft, and then reach the opening of the locking groove. At this time, the user releases the fingers, and the two clamping parts move away from each other under the reaction force of the tissue, and then the end of the clamping handle away from the moving rod slightly rotates a certain angle away from the handle. The sliding block then enters the locking groove from the opening of the locking groove and abuts against the groove wall of the locking groove facing away from the clamping handle, so that the locking block can limit the end of the clamping handle away from the moving rod from continuing to rotate away from the handle, thereby achieving automatic locking of the clamping handle.

When the sliding block moves along the locking groove toward the handle, the sliding block can abut against the first unlocking surface and slide into the unlocking hole along the first unlocking surface. The second elastic member can drive the end of the clamping handle away from the moving rod to move away from the handle via driving the moving rod close to the shearing claw, so that the sliding block can abut against the second unlocking surface and move away from the unlocking hole at the unlocking opening along the second unlocking surface.

[0012] By adopting the above technical scheme, after the tissue is processed, the user can continue to pull the end of the clamping handle away from the moving rod towards the handle with fingers, at this time the sliding block will move along the locking groove towards the handle and slide into the unlocking hole along the first unlocking surface, then the user can release the fingers, the second elastic member will drive the end of the clamping handle away from the moving rod away from the handle by driving the moving rod to be close to the two scissor jaws, at this time the sliding block will abut against the second unlocking surface and move away from the unlocking hole along the second unlocking surface, so that the clamping handle can be separated from the unlocking block, and the two clamping parts can be away from each other.

When the two clamping parts clamp the tissue, the cutting channel is formed between the two cutting grooves 131.

[0040] Specifically, the blade 181 can be made of stainless steel with good toughness, so that the user can pull the end of the cutting handle 182 away from the moving rod 14 towards the handle 15 by fingers to drive the blade 181 to pass through the entire cutting groove 131 along the cutting channel. The stainless steel blade 181 can bend along the arc-shaped cutting groove 131 and cut the tissue. After the user releases the fingers holding the cutting handle 182, the third elastic member 183 will apply a force to the blade 181 to approach the mounting shell 11, so that the blade 181 automatically retracts into the fixed sleeve 12, and the end of the cutting handle 182 away from the moving rod 14 returns to the original position.

[0041] The use process of the first embodiment described in the application is as follows: When the tissue on the patient needs to be treated, the user can first hold the handle 15 to move the tissue closing assembly 1 so that the tissue is located between the two clamping parts. Then the user pulls the end of the clamping handle 16 away from the moving rod 14 towards the handle 15 by fingers. At this time, the clamping handle 16 drives the moving rod 14 away from the fixed sleeve 12, and the moving rod 14 drives the scissor fork shaft 142 away from the hinge shaft of the two scissor fork jaws 13, so that the two clamping parts approach each other and clamp the tissue. The sliding block 1611 abuts against and slides along the corresponding locking surface 1712, so that the top corner of the locking block 171 rotates towards the mounting shell 11. When the two clamping portions clamp the tissue, the slider 1611 will slide along the entire locking surface 1712 and pass the locking block 171 at the end away from the hinge axis of the clamping handle 16, and the slider 1611 can pass the top corner of the locking block 171 and reach the opening of the locking groove 1711, then the user can release the fingers holding the clamping handle 16, at this time the two clamping portions will move away from each other under the reaction force of the tissue, and then the end of the clamping handle 16 away from the moving rod 14 will slightly rotate in the direction away from the handle 15 by a certain angle, and the slider 1611 will enter the locking groove 1711 from the opening of the locking groove 1711 and abut against the side wall of the locking groove 1711 away from the clamping handle 16, so that the end of the clamping handle 16 away from the moving rod 14 is restricted from continuing to rotate in the direction away from the handle 15 by the locking block 171, so as to realize automatic locking of the clamping handle 16, so that the user does not need to keep the fingers pulling the clamping handle 16 during the process of separating and coagulating the tissue by high-frequency current, so that the use of the high-frequency surgical system is more convenient, and the situation that the tissue to be treated is separated from the two clamping portions due to the user's mistake of releasing the clamping handle 16, and then the surgery fails, can be avoided. Then the user can start the high-frequency host assembly to output high-frequency current to the two scissors jaws 13, so as to coagulate the tissue on the patient by the high-frequency current, so as to achieve the purpose of hemostasis; after waiting for a period of time, when the user judges that cutting can be performed, the user can use the fingers to pull the end of the cutting handle 182 away from the moving rod 14 towards the handle 15 to drive the knife blade 181 to cut the tissue between the two clamping portions along the cutting channel, and then release the fingers holding the cutting handle 182, and the third elastic member 183 will apply a force to the knife blade 181 to approach the mounting shell 11, so that the knife blade 181 automatically retracts into the fixed sleeve 12, and the end of the cutting handle 182 away from the moving rod 14 returns to the original position. After the tissue is processed, the user can continue to pull the end of the clamping handle 16 away from the moving rod 14 towards the handle 15 with the fingers, at this time the slider 1611 will move along the locking groove 1711 towards the handle 15 and slide into the unlocking hole along the first unlocking surface 1713, then the user can release the fingers, and the second elastic member 173 will drive the moving rod 14 to approach the two scissors jaws 13 to drive the end of the clamping handle 16 away from the handle 15 at this time, the slider 1611 will abut against the second unlocking surface 1714 and leave the unlocking hole from the unlocking hole along the second unlocking surface 1714, so that the clamping handle 16 can be separated from the unlocking block, and the two clamping portions can move away from each other.

[0042] Referring to Figure 5 , Figure 6 , Figure 8 and Figure 9In the second embodiment, the high-frequency surgical system further comprises a protection assembly 2, which comprises a liquid storage tank 21 and a liquid delivery pipe 22. The liquid storage tank 21 is detachably connected to the mounting shell 11 through an external thread sleeve. The liquid storage tank 21 stores a protection liquid, which can be physiological saline for reducing thermal injury or biological glue for helping tissue coagulation and hemostasis. The tissue closure assembly 1 further comprises a blocking hinge shaft 132. The two shears 13 are hingedly connected to the fixed sleeve 12 through the blocking hinge shaft 132. A waist-shaped hole 1811 is formed in the length direction of the fixed sleeve 12 on the blade 181. The blocking hinge shaft 132 penetrates through the waist-shaped hole 1811 and can slide along the waist-shaped hole 1811. The blade 181 is internally provided with a liquid passage cavity 1812. An outlet hole and an inlet hole are formed in the inner wall of the liquid passage cavity 1812 and open to the outside. The outlet hole is formed in the inner wall of the waist-shaped hole 1811. A cooling waist-shaped hole 143 is formed in the length direction of the moving rod 14. One end of the liquid delivery pipe 22 is fixedly connected to the end of the external thread sleeve away from the tank opening of the liquid storage tank 21. The external thread sleeve can be inserted into the liquid storage tank 21 and block the tank opening of the liquid storage tank 21. The other end of the liquid delivery pipe 22 penetrates through the cooling waist-shaped hole 143 and is fixedly connected to the inlet hole. The shaft of the blocking hinge shaft 132 is provided with a blocking piece 1321, which can be a rubber piece. When the blade 181 does not enter the cutting channel, the blocking piece 1321 is inserted into the outlet hole and blocks the outlet hole. When the blade 181 divides the tissue along the cutting channel, the outlet hole is away from the blocking piece 1321 and is located in the cutting channel.

[0043] The implementation principle of the second embodiment described in the present application is as follows: Since the high-frequency current coagulates the tissue by denaturing the protein through releasing a large amount of heat, the heat will spread to the surrounding tissue to be coagulated and cause a large area of thermal injury on the body of the person to be operated. The user of the high-frequency surgical system generally stands above the person to be operated to perform the operation. Therefore, the state of the tissue closure assembly 1 during use is generally that the liquid storage tank 21 is above, the clamping part and the tissue to be treated are below, the blocking piece 1321 is inserted into the outlet hole and blocks the outlet hole when the blade 181 does not enter the cutting channel, and the outlet hole is away from the blocking piece 1321 and is located in the cutting channel when the blade 181 divides the tissue along the cutting channel. Then, the protection liquid in the liquid storage tank 21 flows out of the outlet hole under the action of gravity along the liquid delivery pipe 22 and the liquid passage cavity 1812, and protects the divided tissue on both sides of the cutting channel. The protection liquid can protect the tissue and organs around the tissue to be coagulated, reduce the thermal injury of the person to be operated, and be beneficial to postoperative recovery.

[0044] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, wherein the same parts are denoted by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
