Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of surgical instruments and equipment, in particular to a bipolar coagulation forceps with adjustable angle. Background Art
[0002] The bipolar coagulation forceps is a new instrument for otolaryngology surgery, which consists of a double-lobe forceps body and an electrode holder. Bipolar electrocoagulation can perform more delicate electrocoagulation hemostasis and treatment on small blood vessels and other structures. The principle is that when the protein is coagulated by heating and the blood vessel is closed, the tissue is heated to the coagulation and boiling point, and the power can be automatically cut off. At the same time, due to the insulation of the blades of the bipolar electrocoagulation, only the current is conducted between the forceps tips. When electrocoagulating, the current flows from one forceps tip to the other, and the tissue between the two forceps tips is affected by the thermal effect of the current, while the tissue outside the forceps tips is less or not affected.
[0003] In a bipolar coagulation forceps with adjustable angle disclosed in the utility model patent CN219629763U of China, the cooperation between the adjusting wheel, the connecting belt and the connecting head realizes the purpose of driving the forceps tip and the connecting head to rotate along the inner wall of the rotating groove. However, in this design, it is necessary to adjust before the operation or stop the operation during the operation and then adjust the angle, which does not conform to the actual use requirements and is difficult to meet the actual needs of users. Therefore, we propose a bipolar coagulation forceps with adjustable angle 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 to propose a bipolar coagulation forceps with adjustable angle.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A bipolar coagulation forceps with adjustable angle, including a coagulation forceps body, one end of the coagulation forceps body is provided with a hinge, a forceps tip is fixedly connected to the side far from the coagulation forceps body, and a control component is further arranged on the lower surface of the coagulation forceps body;
[0007] The control component includes two push rods slidably connected to the lower surface of the coagulation forceps body. A push rod is arranged on the side of the push rod close to the forceps tip. A limiting structure is further arranged on the coagulation forceps body. A sliding groove is opened on the lower surface of the coagulation forceps body, and the push rod is arranged in the sliding groove. A soft rod is arranged at the end of the push rod far from the push rod. A tooth is fixedly connected to the side wall of the soft rod close to the hinge. A clamping groove matching the tooth is opened on the side wall of the hinge. A limiting shell is arranged on the side wall of the coagulation forceps body close to the hinge. The control component can control the rotation of the forceps tip with the middle finger when the user operates the coagulation forceps body.
[0008] Preferably, the limiting structure includes a vertical rod slidably connected to the push rod, the upper end of the vertical rod passes through the push rod, and the upper end of the vertical rod is fixedly connected to a ball head, and rubber pads are provided on the inner walls on both sides of the slide groove, and the spacing between the rubber pads is smaller than the outer diameter of the ball head.
[0009] Preferably, the distances between the two levers and the tweezers tip are different.
[0010] Preferably, a control rod is fixedly connected to the lower end of the vertical rod, and the control rod is in an I-shape.
[0011] Preferably, the limiting shell is arc-shaped, and the inner wall of the limiting shell abuts against the lower surface of the soft rod.
[0012] Preferably, arc-shaped grooves are provided on both sides of the electrocoagulation forceps body, and extended side strips are provided on the side walls of the electrocoagulation forceps body close to the arc-shaped grooves.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model provides a control component. When the user needs to adjust the angle between the forceps tip and the electrocoagulation forceps body, the user uses the middle finger to move the lever, and then uses the push rod to drive the soft rod to move. The clamping teeth on the soft rod cooperate with the clamping grooves on the hinge to achieve the purpose of driving the forceps tip to rotate. In addition, in this type of angle-adjustable bipolar electrocoagulation forceps, the user can make real-time adjustments during the operation, which is more convenient to operate, and the angle adjustment operation can be completed with one hand, which is more flexible to use.
[0015] 2. The utility model provides a limiting structure, so that after the user adjusts the angle between the forceps tip and the electrocoagulation forceps body, the vertical rod can be pushed upward to move the ball head so that the ball head is stuck between the two rubber pads, and then the friction between the rubber pads and the ball head is used to limit the horizontal position of the push rod so that it cannot slide freely. Since the force on the forceps tip is relatively small during the operation, the friction between the rubber pads and the ball head has met the requirement for fixing the forceps tip.

[0021] 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.
[0022] Refer to Figures 1-4 , an angle-adjustable bipolar electrocautery forceps, including an electrocautery forceps body 1, one end of the electrocautery forceps body 1 is provided with a hinge 2, and a forceps tip 3 is fixedly connected to the side far from the electrocautery forceps body 1. A control component is also provided on the lower surface of the electrocautery forceps body 1;
[0023] The control component includes two levers 4 slidably connected to the lower surface of the electrocautery forceps body 1, and the distances between the two levers 4 and the forceps tip 3 are different;
[0024] In this design, the two levers 4 are respectively used to control the two forceps tips 3 on the electrocautery forceps body 1. When the user operates the electrocautery forceps body 1 in actual operation, usually the right hand holds the electrocautery forceps body 1. At this time, the distance between the lever 4 closer to the user's left side and the forceps tip 3 is less than the distance between the lever 4 closer to the user's right side and the forceps tip 3. This design is used to facilitate the user to operate the lever 4 with the middle finger, and when operating the lever 4 closer to the user's left side, it is not easy to drive the lever 4 closer to the user's right side to move, avoiding accidental touch operations;
[0025] One side of the lever 4 close to the forceps tip 3 is provided with a push rod 5. A limiting structure is also provided on the electrocautery forceps body 1. A chute is opened on the lower surface of the electrocautery forceps body 1, and the push rod 5 is arranged in the chute. One end of the push rod 5 far from the lever 4 is provided with a flexible rod 6. A card tooth 8 is fixedly connected to the side wall of the flexible rod 6 close to the hinge 2. A card slot 7 matching the card tooth 8 is opened on the side wall of the hinge 2. A limit shell 9 is provided on the side wall of the electrocautery forceps body 1 close to the hinge 2. The control component can use the middle finger to control the rotation of the forceps tip 3 when the user operates the electrocautery forceps body 1;
[0026] Based on the above design, the user can use the middle finger to move the two push rods 5 on the electrocoagulation forceps body 1 respectively, so that the push rods 5 slide in the direction of approaching or moving away from the forceps tip 3. At this time, the lever 4 drives the push rod 5 to slide along the chute, and then drives the soft rod 6 to move. The teeth 8 on the soft rod 6 cooperate with the slots 7 on the hinge 2, so that the part of the hinge 2 connected to the forceps tip 3 rotates, thereby achieving the purpose of changing the angle of the forceps tip 3. During the operation process, in most cases, only one forceps tip 3 needs to be adjusted in terms of angle. Therefore, using the middle finger to control the two levers 4 can fully meet the requirements, and the operation can be completed with one hand, while maintaining the continuity of the surgical operation.
[0027] Furthermore, the limiting structure includes a vertical rod 10 slidably connected to the push rod 5. The vertical rod 10 is sleeved on the push rod, and the vertical rod 10 can slide up and down relative to the push rod. The upper end of the vertical rod 10 penetrates through the push rod 5, and a ball head 11 is fixedly connected to the upper end of the vertical rod 10. Rubber pads 12 are arranged on both inner walls of the chute, and the distance between the rubber pads 12 is smaller than the outer diameter of the ball head 11.
[0028] Based on the above design, when the user slides the vertical rod 10 up and down so that the ball head 11 is caught in or disengaged from the rubber pad 12, the position of the push rod 5 can be fixed or adjusted. Since the electrocoagulation operation is only performed on soft tissues during the operation, and due to factors such as the transmission ratio between the teeth 8 and the slots 7, the fixing requirement for the lever 4 is relatively low. Using this solution can fully meet the actual application requirements. Multiple vertical convex protection strips can be arranged on the rubber pad 12 to further improve the fixing effect on the ball head 11.
[0029] A control rod 13 is fixedly connected to the lower end of the vertical rod 10. The control rod 13 is in the shape of a capital "I". Since the vertical rod 10 needs to be controlled by the middle finger to move up and down when adjusting the vertical rod 10, and when adjusting, there is a situation of controlling the lever 4 to move in the direction of approaching or moving away from the forceps tip 3, the use of the control rod 13 in the shape of a capital "I" is convenient for the user to operate.
[0030] Furthermore, the limiting shell 9 is arc-shaped, and the inner wall of the limiting shell 9 abuts against the lower surface of the soft rod 6. The limiting shell 9 is provided to ensure that the teeth 8 on the soft rod 6 can engage with the slots 7 on the hinge 2, so as to ensure that the soft rod 6 can drive the part of the hinge 2 connected to the forceps tip 3 to rotate.
[0031] Furthermore, arc-shaped grooves 14 are formed on both sides of the electrocoagulation forceps body 1, and an extended edge strip is arranged on the side wall of the electrocoagulation forceps body 1 close to the arc-shaped grooves 14. Since the limiting structure is provided, a force in the up and down direction will be applied to the electrocoagulation forceps body 1 during use. Therefore, the arc-shaped grooves 14 are provided for the parts where the thumb and index finger contact the electrocoagulation forceps body 1 when the user holds the electrocoagulation forceps body 1, so that the user holds the electrocoagulation forceps body 1 more tightly, and to prevent the electrocoagulation forceps body 1 from slipping out when using the limiting structure.
[0032] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent replacements or changes, shall be covered by the protection scope of the present utility model.
