Description

Technical Field

[0001] This invention belongs to the field of ultrasonic scalpel technology, specifically relating to an ultrasonic scalpel with blood-absorbing function. Background Technology

[0002] Ultrasound is a mechanical wave that does not contain radiation and is harmless to the human body. Ultrasonic scalpel therapy is a non-invasive treatment method that does not require incision or puncture. Ultrasonic scalpels are widely used in open and minimally invasive surgeries. They convert the electrical energy of the main unit into the mechanical energy of the scalpel head through a transducer device.

[0003] Utility model CN215192037U discloses an ultrasonic scalpel with smoke and blood suction functions. It includes an ultrasonic scalpel body, a fixed air duct fixedly connected to the top of the body, an exhaust pipe and a fumigation hood respectively connected to the left and right sides of the fixed air duct, a blade head connected to the right side of the ultrasonic scalpel body, a suction tube fixedly connected to the right side of the bottom of the body, a collection nozzle connected to the right side of the suction tube, a fixed shell fixedly connected to the left side of the bottom of the body, and a connecting shell fixedly connected to the left side of the fixed shell. This utility model, through the coordinated use of the ultrasonic scalpel body, fixed air duct, exhaust pipe, fumigation hood, blade head, collection nozzle, suction tube, handle, fixed shell, blood storage tank, connecting shell, booster pump, mounting plate, housing, movable plate, and shock-absorbing spring, possesses smoke and blood suction functions, enabling rapid collection of smoke and blood, improving surgical efficiency, and facilitating the normal conduct of surgery.

[0004] Current ultrasonic scalpels with suction function deliver blood into the storage tank through a collection nozzle, suction tube, and booster pump. However, because the skin is relatively soft, the suction force of the collection nozzle can cause the skin tissue to block the tube, resulting in poor suction effect. Furthermore, since the collection nozzle is exposed to air, it draws a large amount of air into the storage tank, resulting in a limited internal blood storage capacity. Therefore, a suction device that can expel air is needed to reduce the space occupied by air in the storage tank. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic scalpel with blood-absorbing function to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An ultrasonic scalpel with blood-absorbing function includes:

[0008] The ultrasonic scalpel body has a blade head at one end, a support block on one side surface of the ultrasonic scalpel body, a shell fixedly connected to the lower side of the ultrasonic scalpel body, a blood-drawing device inside the shell, a cylinder on one side of the blood-drawing device, connecting tubes symmetrically inserted into one side of the cylinder, and a transfusion tube fixedly connected to one end of the symmetrical connecting tubes.

[0009] One end of the transfusion tube is fixedly connected to a connecting block, and a blood bottle is inserted into the internal thread of the connecting block. The other end of the transfusion tube is provided with a blood collection component through the support block.

[0010] The blood-drawing device includes a second motor fixedly connected to the inner wall of the outer casing. A gear disk is provided on one side of the second motor, and there are two gear disks. The output end of the second motor is fixedly connected to one of the gear disks through a coupling. A rocker arm is fixedly connected to one end of the symmetrical gear disk. A second connecting rod is hinged to one side of the rocker arm. A second piston is fixedly connected to one side of the second connecting rod. A first connecting rod is hinged to the other side of the rocker arm. A first piston is fixedly connected to one side of the first connecting rod. The first piston is inserted into the axis of the second piston.

[0011] One end of the first piston and the second piston are located inside the cylinder, and one side of the outer wall of the first piston and the second piston slides against the inner wall of the cylinder.

[0012] The cylinder has exhaust pipes symmetrically inserted on one side. One end of each exhaust pipe is located on one side of the first piston and the second piston, respectively. One end of each exhaust pipe is fixedly connected to an outlet pipe, and one end of the outlet pipe passes through the outer shell and communicates with the outside air.

[0013] Both the symmetrical connecting pipe and the symmetrical exhaust pipe are equipped with a second one-way valve inside, and the one-way valves have opposite directions of flow. The connecting pipe is equipped with hemostatic cotton inside.

[0014] As a preferred embodiment of the present invention, the two ends of the rocker are inserted with fixing blocks, and the two ends of the fixing blocks are fixedly connected to the inner wall of the outer shell.

[0015] In a preferred embodiment of the present invention, the blood collection assembly includes a rotating tube symmetrically sleeved on one end of the transfusion tube, a stop ring fixedly connected to one end of the rotating tube, and a rubber pad fixedly connected to one side of the stop ring.

[0016] In a preferred embodiment of the present invention, the rotating tube is fixedly connected to a second transmission wheel at one end of the support block, and a first motor is provided inside the support block. The output end of the first motor is fixedly connected to a first transmission wheel through a coupling, and the two sides of the first transmission wheel mesh with the symmetrical second transmission wheel.

[0017] The beneficial effects of this invention are:

[0018] 1. In this invention, the ultrasonic scalpel body contacts the patient's skin surface through the scalpel head. The ultrasonic scalpel body supports the rotating tube, the retaining ring, and the rubber pad through the surface support block. The rubber pad absorbs blood through the internal infusion tube. Inside the outer shell, the second motor drives the first transmission wheel to rotate through the coupling. On one side of the rotating first transmission wheel, the first piston is pulled repeatedly inside the cylinder by pulling the first connecting rod. On the other side of the rotating first transmission wheel, the second piston is pulled repeatedly inside the cylinder by pulling the second connecting rod. Due to the rotation of the first transmission wheel, the movements of the first and second pistons are opposite. Inside the cylinder, the first and second pistons sequentially provide suction to the inside of the infusion tube through the connecting tube, so that the inside of the infusion tube is continuously filled with suction. Blood flows into the blood bottle through the connecting block due to gravity and the obstruction of the hemostatic cotton. The blood bottle collects the blood. This design allows blood to flow into the blood bottle through the connecting block due to gravity and the obstruction of the hemostatic cotton, and the blood bottle collects the blood.

[0019] 2. A connecting block is fixedly connected to one end of the transfusion tube. A blood bottle is inserted into the internal thread of the connecting block. The connecting block is located at the horizontal end of the transfusion tube. The blood bottle is interconnected with the transfusion tube through the connecting block. A blood collection assembly is installed through the support block at the other end of the transfusion tube. The blood collection assembly includes a rotating tube symmetrically fitted to one end of the transfusion tube. A retaining ring is fixedly connected to one end of the rotating tube. A rubber pad is fixedly connected to one side of the retaining ring. The transfusion tube is divided into two delivery tubes inserted into the interior of the rotating tube. The rotating tubes are abutted by the retaining ring and the rubber pad. The rubber pad reduces the pressure of the retaining ring on the skin and protects the skin tissue. Blood flow grooves are opened around the retaining ring and the rubber pad, allowing the skin tissue surface to enter the interior of the transfusion tube through the retaining ring and the rubber pad, reducing the blockage of the transfusion tube by the skin tissue.

[0020] 3. In this invention, a stop ring is fixedly connected to one end of the rotating tube, and a rubber pad is fixedly connected to one side of the stop ring. The infusion tube is divided into two delivery tubes inserted into the interior of the rotating tube. The rotating tubes are abutted by the stop ring and the rubber pad. The rubber pad reduces the pressure of the stop ring on the skin and protects the skin tissue. Blood flow grooves are opened around the stop ring and the rubber pad, so that the skin tissue surface can enter the interior of the infusion tube through the periphery of the stop ring and the rubber pad, reducing the blockage of the infusion tube by the skin tissue.

[0032] 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 a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example

[0033] Please see the appendix Figures 1-6 An ultrasonic scalpel with blood-absorbing function includes:

[0034] The ultrasonic scalpel body 1 has a blade head 11 at one end. The ultrasonic scalpel body 1 vibrates the skin through the blade head 11. The ultrasonic scalpel can make the blade head mechanically vibrate at an ultrasonic frequency of 55.5KHz, which can vaporize the liquid and coagulate the protein in the tissue. A support block 3 is sleeved on one side surface of the ultrasonic scalpel body 1. A shell 2 is fixedly connected to the lower side of the ultrasonic scalpel body 1. A blood-drawing device 4 is installed inside the shell 2. The shell 2 protects the blood-drawing device 4 inside.

[0035] The blood-drawing device 4 includes a second motor 41 fixedly connected to the inner wall of the outer casing 2. A gear disk 42 is provided on one side of the second motor 41, and there are two gear disks 42. The two gear disks 42 mesh with each other. The output end of the second motor 41 is fixedly connected to one of the gear disks 42 through a coupling. A rocker arm 43 is fixedly connected to one end of the symmetrical gear disk 42. A second connecting rod 45 is hinged to one side of the rocker arm 43. A second piston 47 is fixedly connected to one side of the second connecting rod 45. A first connecting rod 44 is hinged to the other side of the rocker arm 43. A first piston 46 is fixedly connected to one side of the first connecting rod 44. The first piston 46 is inserted into the axis of the second piston 47. The first transmission wheel 32 supports the first connecting rod 44 and the second connecting rod 45 on both sides respectively. The first connecting rod 44 and the second connecting rod 45 are both composed of two connecting rods hinged together.

[0036] Please see the appendix Figures 1-3 A cylinder 8 is provided on one side of the blood drawing device 4. A connecting tube 51 is symmetrically inserted into one side of the cylinder 8. One end of the symmetrical connecting tube 51 is fixedly connected to a transfusion tube 5. The transfusion tube 5 is a rubber hose. The surface of the transfusion tube 5 is fixed to the lower side of the ultrasonic scalpel body 1 by a buckle. One end of the first piston 46 and the second piston 47 is located inside the cylinder 8, and one side of the outer wall of the first piston 46 and the second piston 47 slides against the inner wall of the cylinder 8. A rubber sealing ring is fixedly connected to the contact surface between the first piston 46 and the second piston 47 and the inner wall of the cylinder 8 to increase the sealing effect between the cylinder 8 and the outer wall of the first piston 46 and the second piston 47.

[0037] Please see the appendix Figures 1-3 The second motor 41 drives the first transmission wheel 32 to rotate via a coupling. On one side of the first transmission wheel 32, the first piston 46 is pulled repeatedly inside the cylinder 8 by the first connecting rod 44. On the other side of the first transmission wheel 32, the second piston 47 is pulled repeatedly inside the cylinder 8 by the second connecting rod 45. Due to the rotation of the first transmission wheel 32, the movements of the first piston 46 and the second piston 47 are opposite. Inside the cylinder 8, the first piston 46 and the second piston 47 sequentially provide suction to the inside of the infusion tube 5 through the connecting pipe 51, so that the inside of the infusion tube 5 is continuously filled with suction.

[0038] Please see the appendix Figures 2-4A symmetrical exhaust pipe 81 is inserted into one side of the cylinder 8. One end of the symmetrical exhaust pipe 81 is located on one side of the first piston 46 and the second piston 47, respectively. One end of the symmetrical exhaust pipe 81 is fixedly connected to an exhaust pipe 82. The exhaust pipe 82 communicates with the inside of the cylinder 8 through the symmetrical exhaust pipe 81. One end of the exhaust pipe 82 passes through the outer shell 2 and communicates with the outside air. The exhaust pipe 81 discharges the air pushed by the first piston 46 and the second piston 47 inside the cylinder 8 on one side. The exhaust pipe 81 discharges the air into the atmosphere through the exhaust pipe 82.

[0039] Please see the appendix Figures 3-5 One end of the transfusion tube 5 is fixedly connected to a connecting block 6. A blood bottle 7 is inserted into the internal thread of the connecting block 6. The connecting block 6 is located at the horizontal end of the transfusion tube 5. The blood bottle 7 is interconnected with the transfusion tube 5 through the connecting block 6. The symmetrical connecting pipe 51 and the symmetrical exhaust pipe 81 are both equipped with a second one-way valve 811. The symmetrical one-way valves 811 have opposite directions of flow. The connecting pipe 51 is equipped with hemostatic cotton. The one-way valve 811 inside the connecting pipe 51 generates suction through the cylinder 8 to draw in air. Due to gravity and the obstruction of the hemostatic cotton, the blood flows into the blood bottle 7 through the connecting block 6. The blood bottle 7 collects the blood. The blood bottle 7 is inserted into the connecting block 6 through a knob. The rotation of the blood bottle 7 makes it easy to disassemble and replace. The two ends of the rocker arm 43 are connected to fixing blocks 48. The two ends of the symmetrical fixing blocks 48 are fixedly connected to the inner wall of the outer shell 2. The fixing blocks 48 limit the two sides of the rocker arm 43 to increase the stability of the rotation of the rocker arm 43.

[0040] Please see the appendix Figures 4-6 The other end of the infusion tube 5 passes through the support block 3 and is equipped with a blood collection component 9. The blood collection component 9 includes a rotating tube 91 symmetrically sleeved on one end of the infusion tube 5. One end of the rotating tube 91 is inserted into the interior of the support block 3. A retaining ring 92 is fixedly connected to one end of the rotating tube 91. A rubber pad 93 is fixedly connected to one side of the retaining ring 92. The rubber pad 93 has a circular structure. One end of the infusion tube 5 is divided into two delivery tubes inserted into the interior of the rotating tube 91. The rotating tube 91 is abutted by the retaining ring 92 and the rubber pad 93. The rubber pad 93 reduces the pressure of the retaining ring 92 on the skin and protects the skin tissue. Blood flow grooves are opened around the retaining ring 92 and the rubber pad 93 so that the skin tissue surface enters the interior of the infusion tube 5 through the periphery of the retaining ring 92 and the rubber pad 93, reducing the blockage of the infusion tube 5 by the skin tissue.

[0041] Please see the appendix Figures 4-6The rotating tube 91 is fixedly connected to a second transmission wheel 94 at one end of the support block 3. The support block 3 is equipped with a first motor 31. The output end of the first motor 31 is fixedly connected to a first transmission wheel 32 through a coupling. The two sides of the first transmission wheel 32 mesh with the symmetrical first transmission wheel 32. The first motor 31 drives the second transmission wheel 94 to rotate through the first transmission wheel 32. The second transmission wheel 94 drives the abutment ring 92 and the rubber pad 93 to rotate through the rotating tube 91, so that blood and air can enter the interior of the blood transfusion tube 5 through the blood flow groove.

[0042] Working principle:

[0043] The ultrasonic scalpel body 1 contacts the patient's skin surface through the scalpel head 11. The ultrasonic scalpel body 1 supports the rotating tube 91, the abutment ring 92, and the rubber pad 93 via the surface support block 3. The rubber pad 93 absorbs blood through the internal infusion tube 5. Inside the outer shell 2, the second motor 41 drives the first transmission wheel 32 to rotate via a coupling. On one side of the rotating first transmission wheel 32, the first piston 46 is pulled repeatedly inside the cylinder 8 via the first connecting rod 44. On the other side of the rotating first transmission wheel 32, the second piston 47 is pulled repeatedly inside the cylinder 8 via the second connecting rod 45. Due to the rotation of the first transmission wheel 32, the movements of the first piston 46 and the second piston 47 are opposite. Inside the cylinder 8, the first piston 46 and the second piston 47 are sequentially connected via the connecting tube 51. The system provides suction to the inside of the transfusion tube 5, ensuring it remains continuously filled with suction. Due to gravity and the obstruction of the hemostatic cotton, blood flows into the blood bottle 7 through the connecting block 6. The blood bottle 7 collects the blood. This design, where blood flows into the blood bottle 7 through the connecting block 6 due to gravity and the obstruction of the hemostatic cotton, and the blood bottle 7 collects the blood, reduces skin blockage of the transfusion tube 5 by using a blood flow groove on one side of the rotating tube 91 and the ring 92 and the rubber pad 93. The gear disk 42, rocker arm 43, and first connecting rod 44 driven by the second motor 41 cause the first piston 46 and the second piston 47 to slide repeatedly inside the cylinder 8, providing suction to the transfusion tube 5, reducing the entry of air into the blood bottle 7, and improving the storage efficiency of the blood bottle 7.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
