Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to an airbag type bipolar coagulation forceps. Background Art

[0002] Electrocoagulation for surgical hemostasis has a long origin, and the current used in surgery is high-frequency current (with a frequency of several thousand to more than 2 million cycles per second). By applying high-frequency current, even if the voltage is as high as several thousand volts, it can safely pass through the human body without causing nerve or muscle reactions. Utilizing the thermal effect of high-frequency current, the blood vessel wall is dehydrated and shrunk, the blood in the blood vessel is coagulated, and the blood vessel and the blood clot are integrated into one, so as to achieve the purpose of effective hemostasis. The bipolar coagulation forceps is exactly a hemostatic forceps designed based on electrocoagulation.

[0003] In an airbag type bipolar coagulation forceps disclosed in the utility model patent CN220632203U of our country, an arm end airbag capable of being inflated and bulged is arranged on one side of the main body. The gas is transported into the arm end airbag and the tip airbag through the connecting pipe and the gas delivery pipe by squeezing the airbag ball. After the arm end airbag is inflated, it forms a structure similar to a soft brain spatula, which can be used to pull the brain tissue. However, in this design, the airbag balls are arranged on both sides of the main body. During the actual operation, the position of the airbag balls will be above the Hegu (the web between the thumb and index finger) position on the doctor's hand, and the doctor's thumb and index finger are in the state of holding the coagulation forceps, resulting in the user needing to use the other hand to operate the airbag balls, which is easy to accidentally touch or cause the position of the bipolar coagulation forceps to shift, posing a greater risk in use and having a problem of unreasonable design. This makes it difficult for this kind of airbag type bipolar coagulation forceps to be directly applied in actual operations. Therefore, we propose an airbag type bipolar coagulation forceps to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems existing in the prior art, and propose an airbag type bipolar coagulation forceps.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] An airbag type bipolar coagulation forceps, including a coagulation forceps main body, an airbag assembly is arranged on the coagulation forceps main body, and a control assembly is arranged on the coagulation forceps main body;

[0007] The control assembly includes two sheaths fixedly connected to the coagulation forceps main body. A piston is slidably connected in each sheath, and a driving rod is fixedly connected to one side of the piston. The two driving rods are respectively provided with a middle finger ring and a ring finger ring at the ends far away from the piston. A limiting mechanism is also arranged on the piston. When the user holds the coagulation forceps main body, the middle finger and the ring finger can be used to control the airbag assembly;

[0008] The sleeve is connected to the airbag assembly through a hose.

[0009] Preferably, the airbag assembly includes a sunk groove formed on the side wall of the main body of the electrocoagulation forceps. A rubber bladder is arranged in the sunk groove, and the rubber bladder is connected to the sleeve through a hose.

[0010] Preferably, the limiting mechanism includes an inclined rod fixedly connected to the sleeve. A spherical block is fixedly connected to the side wall of the inclined rod close to the driving rod, and a friction plate is fixedly connected to the side wall of the inclined rod close to the spherical block. A friction block is fixedly connected to the side wall of the driving rod close to the inclined rod.

[0011] Preferably, chamfers are arranged on both sides of the friction block, and a tooth is fixedly connected to the side of the friction block close to the inclined rod. A card slot matching the tooth is formed on the friction plate.

[0012] Preferably, the middle finger ring is arranged above the ring finger ring, and the driving rod connected to the ring finger ring is inclined.

[0013] Preferably, limiting grooves are formed on both sides of the main body of the electrocoagulation forceps, and diamond-shaped anti-slip protrusions are arranged in the limiting grooves.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0024] Refer to Figures 1 - 5 , an airbag type bipolar electrocoagulation forceps, including the main body 1 of the electrocoagulation forceps, an airbag assembly is arranged on the main body 1 of the electrocoagulation forceps, and a control assembly is arranged on the main body 1 of the electrocoagulation forceps;

[0025] The control assembly includes two sheaths 2 fixedly connected to the main body 1 of the electrocoagulation forceps. A piston 4 is slidably connected in each of the sheaths 2. One side of the piston 4 is fixedly connected with a driving rod 3. The middle finger ring 5 and the ring finger ring 6 are respectively arranged at the ends of the two driving rods 3 away from the piston 4. A limiting mechanism is also arranged on the piston 4. When the user holds the main body 1 of the electrocoagulation forceps, the user can use the middle finger and the ring finger to control the airbag assembly;

[0026] The sheath 2 is communicated with the airbag assembly through a hose 7.

[0027] Furthermore, the airbag assembly includes a sunk groove 8 opened on the side wall of the main body 1 of the electrocoagulation forceps. A rubber bladder 9 is arranged in the sunk groove 8. The rubber bladder 9 is communicated with the sheath 2 through a hose 7. The sunk groove 8 is provided to accommodate the rubber bladder 9 to avoid the rubber bladder 9 affecting the user's surgical operation under normal conditions.

[0028] Furthermore, the limiting mechanism includes an inclined rod 10 fixedly connected to the sleeve 2. Since the closer to the connection point of the inclined rod 10 and the sleeve 2, the greater the force required for the elastic deformation of the inclined rod 10, the inclined rod 10 is arranged obliquely to ensure that the force required for the user to control the airbag assembly is relatively balanced. A spherical block 11 is fixedly connected to the side wall of the inclined rod 10 close to the driving rod 3, and a friction plate 12 is fixedly connected to the side wall of the inclined rod 10 close to the spherical block 11. A friction block 13 is fixedly connected to the side wall of the driving rod 3 close to the inclined rod 10. The inclined rod 10 is made of an elastic material. The spherical block 11 and the friction block 13 are used to make the user need to first use the friction block 13 to push the spherical block 11 to cause large deformation of the inclined rod 10 when controlling the expansion of the rubber bladder 9, and a relatively large force is required to freely control the expansion or contraction of the rubber bladder 9, so as to avoid the rubber bladder 9 expanding due to accidental touch by the user during the operation and ensure the safety of the operation.

[0029] Furthermore, chamfers are provided on both sides of the friction block 13, and a tooth 14 is fixedly connected to the side of the friction block 13 close to the inclined rod 10. A card slot matching the tooth 14 is provided on the friction plate 12. The tooth 14 and the card slot are provided to increase the resistance when the friction block moves away from the piston 4. Due to the elasticity of the rubber bladder 9 itself, the friction block 13 moves towards the piston 4, so that the resistance when the rubber bladder 9 expands is greater than the resistance when the friction block 13 moves away from the piston 4. Therefore, the tooth 14 and the card slot are provided for balance.

[0030] Furthermore, the middle finger ring 5 is arranged above the ring finger ring 6, and the driving rod 3 connected to the ring finger ring 6 is arranged obliquely. In this design, referring to the ergonomic design, when the user operates this kind of electrocoagulation forceps with the right hand, the ring finger is located below the middle finger, and the ring finger is relatively less flexible compared to the index finger and the middle finger. Therefore, the obliquely arranged driving rod 3 is used to cooperate with it to change the direction of the force applied by the user, making it the same as the direction of the force applied by the ring finger when a person holds an object.

[0031] Furthermore, limiting grooves 15 are provided on both sides of the electrocoagulation forceps main body 1, and diamond-shaped anti-slip protrusions are arranged in the limiting grooves 15. The limiting grooves 15 and the diamond-shaped anti-slip protrusions are used to improve the clamping effect of the thumb and index finger of the user operating the electrocoagulation forceps main body 1 on the electrocoagulation forceps main body 1, especially to prevent the electrocoagulation forceps main body 1 from shifting when the user operates the control assembly.

[0032] In this balloon-type bipolar coagulation forceps, the specific operation method is similar to that of the bipolar coagulation forceps in the prior art. The only difference is that the user needs to insert the middle finger and the ring finger into the middle finger ring 5 and the ring finger ring 6 respectively. When the user needs to inflate the rubber bladder 9, the middle finger or the ring finger moves towards the palm, driving the drive rod 3 to move towards the housing 2, so that the piston 4 drives the air in the housing 2 to flow into the rubber bladder 9 through the hose 7, and then the rubber bladder 9 expands. With this design, single-handed operation can be achieved while being more flexible and convenient, without the need to borrow the other hand for adjustment, meeting the actual needs of users.

[0033] The above is only a preferred specific embodiment 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 of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
