Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically a hand-controlled bipolar electrosurgical unit for separating fascia. Background Technology

[0002] Bipolar electrosurgical units are commonly used tools in surgery. They utilize high-frequency current to generate heat through tissue, which can be used to cut tissue, stop bleeding, and coagulate tissue, facilitating surgical procedures. Using bipolar electrosurgical units can reduce bleeding, improve surgical efficiency, and help shorten the patient's postoperative recovery time. In surgery, surgeons select different surgical tools and techniques as needed to complete the procedure.

[0003] In some existing surgical procedures, the use of bipolar electrosurgical units is required for delicate operations. Traditional bipolar electrosurgical units are chopstick-shaped, and during electrocoagulation, the two poles need to be brought together and controlled by the feet for electrocoagulation and hemostasis. Poor alignment of the two poles is prone to occur, and the coordination of hands and feet can easily cause short-distance displacement of the local area, affecting the surgical operation and intraoperative hemostasis. In addition, blunt dissection of the fascia is required during the operation, and the current bipolar electrosurgical unit cannot achieve the function of blunt dissection. All these factors combined cause many inconveniences in the surgical operation and affect the efficiency of the operation. Summary of the Invention

[0004] The purpose of this invention is to provide a hand-controlled bipolar electrosurgical unit for separating fascia, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hand-controlled bipolar electrosurgical unit for fascia separation, comprising an installation cylinder and a fixing clamp. The fixing clamp is fixedly connected to the top of the installation cylinder and is parrot-beak shaped. A movable clamp is movably installed at the connection between the top side of the installation cylinder and the bottom side of the fixing clamp. A second electrode plate and a first electrode plate are respectively provided on the top surface of the movable clamp and the inner side of the fixing clamp. A through internal cavity is opened at the bottom of the installation cylinder. A fixed shaft is fixedly connected inside the fixing clamp. The upper end of the movable clamp is rotatably sleeved on the outside of the fixed shaft. A torsion spring is fixedly connected between the movable clamp and the inner wall of the fixing clamp. A connecting block is fixedly provided on the inner arc surface of the movable clamp. A traction assembly is provided inside the internal cavity. The upper end of the traction assembly is fixedly connected to the connecting block. A control assembly is movably sleeved at the bottom of the installation cylinder. A sterilization assembly is provided inside the fixing clamp and the installation cylinder.

[0006] Preferably, the traction assembly includes a rigid rope, a limiting rod, and a fixing sleeve. Both ends of the rigid rope are fixedly connected to the bottom surface of the connecting block. There are two limiting rods, both of which are fixedly connected in the internal cavity. The rigid rope is wrapped around the outside of the limiting rods. The fixing sleeve is fixedly sleeved inside the internal cavity. The top of the fixing sleeve has a small hole and is movably sleeved with the rigid rope.

[0007] Preferably, the control assembly includes a control lever, a movable plate, a push plate, a positioning sleeve, and a spring. The positioning sleeve is fixedly fitted inside the inner cavity. The control lever is movably fitted inside the inner cavity along the bottom end of the mounting cylinder. The movable plate is movably fitted inside the inner cavity and fixedly connected to the top end of the control lever. The push plate is fixedly connected to the top surface of the movable plate. The spring is fixedly connected between the positioning sleeve and the movable plate.

[0008] Preferably, the top surface of the positioning sleeve is provided with an adapter opening, the top end of the push plate moves through the adapter opening, the positioning sleeve is located below the limiting rod, and the two limiting rods are symmetrically distributed on both sides above the push plate.

[0009] Preferably, a sealing sleeve is fixedly connected to the bottom surface of the mounting cylinder, the sealing sleeve is fitted on the outside of the control lever, and a sealing gasket is provided inside the sealing sleeve.

[0010] Preferably, the disinfection assembly includes a spray sleeve, a spray hole, and a connecting tube. The spray sleeve is fixedly fitted inside the fixing clamp. The spray sleeve passes through the inner side of the fixing clamp and extends outward. The spray hole is opened on the outer end face of the spray sleeve. The upper end of the connecting tube is fixedly connected to the bottom surface of the spray sleeve. The lower end of the connecting tube passes through the fixing clamp and extends into the mounting cylinder and communicates with the lower part of the internal cavity.

[0011] Preferably, the mounting cylinder has a side hole on its front side, which is connected to the internal cavity. The side hole is located above the lower end of the connecting pipe and below the movable plate, and a sealing plug is movably fitted inside the side hole.

[0012] Preferably, the outer surfaces of the fixing clamps are all arc-shaped, and the fixing clamps are made of flexible material.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention utilizes a combination of a control component and a traction component to achieve swing control of the movable forceps. During surgical procedures, both the fixed forceps and the movable forceps remain open. On one hand, the parrot-beak-shaped structure of the fixed forceps enables blunt dissection of the fascia, avoiding fascial injury. On the other hand, the swinging movable forceps can close with the parrot-beak-shaped fixed forceps when needed, completing the accurate separation, location, and clamping of the blood vessels to be operated on, and enabling precise electrocoagulation and electrocautery operations. This integrates blunt dissection and electrocoagulation operations during surgery, greatly improving the stability and convenience of the surgical procedure, increasing surgical efficiency, and achieving good results.

[0015] 2. This invention utilizes the movement of the control component again, in conjunction with the disinfection component added to the fixing clamp and the mounting cylinder. The movable plate divides the lower part of the internal cavity into independent cavities. The isolated independent cavities are filled with disinfectant liquid beforehand through the side holes. When needed, the control lever is pulled down in the opposite direction, causing the movable plate to compress and store the disinfectant liquid downwards, thus quickly guiding and squeezing the disinfectant liquid upwards. This, combined with the spray sleeve, disinfects the areas to be contacted by the fixing clamp and the movable clamp. The disinfection process is convenient and provides a simple and convenient disinfection effect for complex locations, with good performance. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 6As shown, this embodiment of the invention provides a hand-controlled bipolar electrosurgical unit for fascia separation, including a mounting cylinder 1 and a fixing clamp 2. The fixing clamp 2 is fixedly connected to the top of the mounting cylinder 1 and is parrot-beak shaped. A movable clamp 4 is movably mounted at the connection between the top side of the mounting cylinder 1 and the bottom side of the fixing clamp 2. The top surface of the movable clamp 4 and the inner side of the fixing clamp 2 are respectively provided with a second electrode plate 6 and a first electrode plate 5. The bottom of the mounting cylinder 1 has a through internal cavity 3. A fixing shaft 7 is fixedly connected inside the fixing clamp 2. The upper end of the movable clamp 4 is rotatably sleeved on the outside of the fixing shaft 7. A torsion spring 8 is fixedly connected between the movable clamp 4 and the inner wall of the fixing clamp 2. A connecting block 9 is fixedly provided on the inner arc surface of the movable clamp 4. A traction component 10 is provided inside the internal cavity 3. The upper end of the traction component 10 is fixedly connected to the connecting block 9. A control component 12 is movably sleeved on the bottom of the mounting cylinder 1. A disinfection component 15 is provided inside the fixing clamp 2 and the mounting cylinder 1.

[0025] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, during operation, when separating the fascia surface, the fixation clamp 2 (the part protruding from the parrot's beak) of the bipolar electrosurgical head is first used to bluntly separate along the tumor surface capsule. When a blood vessel is encountered, the fixation clamp 2 of the electrosurgical head is used to separate the blood vessel. Then, the control component 12 is grasped and the control rod 121 is pushed into the internal cavity 3, so that the movable plate 122 moves upward along the internal cavity 3. While compressing the spring 125, the push plate 123 passes through the positioning sleeve 124 and pushes the rigid rope 101 between the two sets of limiting rods 102, so that the rigid rope 101 folds downward. Then, with the guidance of the limiting rods 102 on both sides, the two ends of the rigid rope 101 pull the connecting block 9 downward at the same time, causing the movable clamp 4 to rotate clockwise upward around the fixed axis 7. The torsion spring 8 twists, so that the movable clamp 4 gradually closes with the parrot's beak of the fixation clamp 2 and bites the blood vessel. At this time, the two sides of the blood vessel are in contact with the first electrode plate 5 and the second electrode plate 6 respectively. The thumb presses the electrocoagulation button on the contactor on the mounting cylinder 1 to complete the electrocoagulation.

[0026] First, by utilizing the control component 12 in conjunction with the traction component 10, the swing control of the movable clamp 4 is achieved. During the surgical procedure, the fixed clamp 2 and the movable clamp 4 remain open. On one hand, the parrot-beak-shaped structure of the fixed clamp 2 enables blunt dissection of the fascia, avoiding fascia injury. On the other hand, the swinging movable clamp 4 closes with the parrot-beak-shaped fixed clamp 2 when needed, completing the accurate separation, location, and clamping of the blood vessel to be operated on, and enabling precise electrocoagulation and electrocautery operations. This integrates blunt dissection and electrocoagulation operations during surgery, greatly improving the stability and convenience of the surgical procedure, increasing surgical efficiency, and achieving good results.

[0027] Example 2: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, before use, first open the sealing plug 14 and inject a certain amount of disinfectant alcohol liquid along the side hole 13. The disinfectant liquid fills the bottom of the internal cavity 3 and is located below the movable plate 122. Cover the sealing plug 14. When disinfection is required, pull the control lever 121 outward in the opposite direction, so that the movable plate 122 moves down to compress the disinfectant liquid filled at the bottom of the internal cavity 3. The spring 125 is stretched, and the compressed disinfectant liquid is quickly injected into the spray sleeve 151 through the connecting tube 153 in the disinfection assembly 15. The disinfectant liquid is sprayed out through the spray hole 152 towards the inner side of the fixed clamp 2 and the top surface of the movable clamp 4 to complete the disinfection treatment.

[0028] First, by utilizing the movement of the control component 12 again, in conjunction with the disinfection component 15 added to the fixed clamp 2 and the mounting cylinder 1, the lower part of the internal cavity 3 is divided into independent cavities by the movable plate 122. The isolated independent cavities are filled with disinfectant liquid beforehand through the side hole 13. When needed, by pulling down the control lever 121 in the opposite direction, the movable plate 122 is driven downward to compress and store the disinfectant liquid, thus completing the rapid upward guidance and extrusion of the disinfectant liquid. In conjunction with the spray sleeve 151, the disinfectant liquid is directed towards the contact position of the fixed clamp 2 and the movable clamp 4 for disinfection treatment. The disinfection treatment is convenient and has a simple and convenient disinfection effect for complex positions, with good usage effect.

[0029] The traction assembly 10 includes a rigid rope 101, a limiting rod 102, and a fixing sleeve 103. Both ends of the rigid rope 101 are fixedly connected to the bottom surface of the connecting block 9. There are two limiting rods 102, both fixedly connected within the internal cavity 3. The rigid rope 101 is wound around the outside of the limiting rods 102. The fixing sleeve 103 is fixedly sleeved inside the internal cavity 3, and a small hole is opened at the top of the fixing sleeve 103, which is movably connected to the rigid rope 101. The traction assembly 10 enables the movable clamp 4 to be pulled, completing its rotation around the fixed shaft 7. The torsion spring 8 facilitates elastic reset. The winding of the rigid rope 101, combined with the arrangement of the limiting rods 102, allows the rigid rope 101 to fold when pushed from the middle, thus completing the traction control.

[0030] The control assembly 12 includes a control lever 121, a movable plate 122, a push plate 123, a positioning sleeve 124, and a spring 125. The positioning sleeve 124 is fixedly sleeved inside the inner cavity 3. The control lever 121 is movably sleeved in the inner cavity 3 along the bottom end of the mounting cylinder 1. The movable plate 122 is movably sleeved in the inner cavity 3 and fixedly connected to the top of the control lever 121. The push plate 123 is fixedly connected to the top surface of the movable plate 122. The spring 125 is fixedly connected between the positioning sleeve 124 and the movable plate 122.

[0031] The control component 12 is used to pull the component 10, thereby rotating the movable clamp 4. When the movable plate 122 moves downward, the disinfectant liquid is squeezed out. The spring 125 is used to maintain the position relatively stable and reset by using elasticity, so as to prevent it from sliding up and down randomly under gravity.

[0032] The top surface of the positioning sleeve 124 is provided with an adapter opening, the top of the push plate 123 moves through the adapter opening, the positioning sleeve 124 is located below the limiting rod 102, and the two limiting rods 102 are symmetrically distributed on both sides above the push plate 123.

[0033] By using the positioning sleeve 124 to limit the connection of one end of the spring 125, and by limiting the position of the limiting rod 102 and the push plate 123, the rigid rope 101 is fully folded when pushed.

[0034] The bottom surface of the mounting cylinder 1 is fixedly connected to a sealing sleeve 11, which is fitted onto the outside of the control lever 121. A sealing gasket is provided inside the sealing sleeve 11.

[0035] The sealing sleeve 11, together with the internal sealing gasket, maintains the dynamic seal of the control lever 121, maintaining sliding while reducing leakage and ensuring that the disinfectant liquid does not leak.

[0036] The disinfection component 15 includes a spray sleeve 151, a spray hole 152, and a connecting tube 153. The spray sleeve 151 is fixedly fitted inside the fixing clamp 2. The spray sleeve 151 passes through the inner side of the fixing clamp 2 and extends out. The spray hole 152 is opened on the outer end face of the spray sleeve 151. The upper end of the connecting tube 153 is fixedly connected to the bottom surface of the spray sleeve 151. The lower end of the connecting tube 153 passes through the fixing clamp 2 and extends into the mounting cylinder 1 and is connected to the lower part of the internal cavity 3.

[0037] By utilizing the positioning of the disinfection component 15, when the stored disinfectant liquid is pressed down by the movable plate 122, the disinfection process is completed by guiding the liquid to spray out.

[0038] The mounting cylinder 1 has a side hole 13 on its front side, which is connected to the internal cavity 3. The side hole 13 is located above the lower end of the connecting pipe 153 and below the movable plate 122. A sealing plug 14 is movably fitted inside the side hole 13.

[0039] By limiting the position of the side hole 13, the injection effect of disinfectant liquid is improved, and a certain amount of storage is achieved. The sealing plug 14 is used for sealing.

[0040] The outer surfaces of the fixing clamp 2 are all curved, and the fixing clamp 2 is made of flexible material.

[0041] The outer surface of the clamp 2 is made of a non-conductive biomimetic material with a softness similar to that between the fingers, thus avoiding damage to the tissue.

[0042] The working principle and usage process of this invention are as follows: During surgery, when separating the fascia surface, the fixation clamp 2 (the part protruding like a parrot's beak) of the bipolar electrosurgical head is first used to bluntly separate along the tumor surface capsule. When a blood vessel is encountered, the fixation clamp 2 of the electrosurgical head is used to separate the blood vessel. Then, the control component 12 is grasped, and the control rod 121 is pushed into the internal cavity 3, causing the movable plate 122 to move upward along the internal cavity 3. While compressing the spring 125, the push plate 123 passes through the positioning sleeve 124 and pushes the rigid rope 101 between the two sets of limiting rods 102, causing the rigid rope 101 to fold downward. Then, in conjunction with the guidance of the limiting rods 102 on both sides, the two ends of the rigid rope 101 pull the connecting block 9 downward at the same time, causing the movable clamp 4 to rotate clockwise upward around the fixed axis 7. The torsion spring 8 twists, causing the movable clamp 4 to gradually engage with the fixed axis 7. The parrot beak of the fixing clamp 2 closes and bites the blood vessel. At this time, the two sides of the blood vessel are in contact with electrode plate 5 and electrode plate 6 respectively. Press the electrocoagulation button on the contactor on the mounting cylinder 1 with your thumb to complete the electrocoagulation. Before use, open the sealing plug 14 and inject a certain amount of disinfectant alcohol liquid along the side hole 13. The disinfectant liquid fills the bottom of the internal cavity 3 and is located below the movable plate 122. Cover the sealing plug 14. When disinfection is required, pull the control lever 121 outward in the opposite direction, so that the movable plate 122 moves down and compresses the disinfectant liquid filled at the bottom of the internal cavity 3. The spring 125 is stretched, and the compressed disinfectant liquid is quickly injected into the spray sleeve 151 through the connecting tube 153 in the disinfection component 15. The disinfectant liquid is sprayed out through the spray hole 152 towards the inner side of the fixing clamp 2 and the top surface of the movable clamp 4 to complete the disinfection.
