Description

Technical Field

[0001] This utility model relates to the field of surgical instrument technology, specifically an anti-adhesion electrocoagulation forceps. Background Technology

[0002] Microsurgery refers to the delicate surgical procedures performed by surgeons using a surgical microscope to magnify small tissues with fine microsurgical instruments and suture materials. Electrocautery forceps are a type of microsurgical instrument used for electrocautery hemostasis. As a common feature of microsurgery, electrocautery forceps are used very frequently. During microsurgery, surgeons and medical assistants need to frequently pass electrocautery forceps between each other until the surgery is completed.

[0003] Existing electrocoagulation forceps have several drawbacks during use. When used for hemostasis, they come into contact with the tissue surrounding the blood vessels, causing the forceps tips to stick together. This can lead to rebleeding of the surrounding tissue during the procedure. Additionally, when using saline infusion, the infusion direction changes depending on the direction the forceps are held, making it difficult to accurately apply the saline to the eschar, which is not conducive to solving the adhesion problem of the forceps.

[0004] Therefore, those skilled in the art have provided an anti-adhesion electrocoagulation forceps to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an anti-adhesion electrocoagulation forceps to solve the problem mentioned in the background art, where the tips of existing electrocoagulation forceps tend to stick together during hemostasis because they come into contact with the tissues surrounding the blood vessels, leading to rebleeding of the surrounding tissues during the operation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An anti-adhesion electrocautery forceps includes: an electrocautery forceps body; a disassembly groove is provided at the lower end of the electrocautery forceps body, and a forceps tip is installed inside the disassembly groove; a conductive tip is connected to the lower end of the forceps tip; an inlet tube is connected to the upper end of the forceps tip; a sliding switch is installed on the outer wall of the electrocautery forceps body; an injection tube is installed at the top of the electrocautery forceps body, and a shunt tube is connected to the lower end of the injection tube; power terminals are installed on both the left and right sides of the top of the electrocautery forceps body, and a power-connecting copper post is inserted inside the power terminal; a circuit box is installed at the upper end of the power-connecting copper post, and a resistor is electrically connected to the upper end of the circuit box; a connecting piece is provided at one end of the resistor.

[0008] As a further embodiment of this utility model: the resistor is electrically connected to the circuit inside the circuit box, the copper post connected to the tip of the electrocautery tweezers body is electrically connected through the connecting end, the circuit box is symmetrical about the center line of the electrocautery tweezers body, and a rotating shaft is provided between the circuit boxes.

[0009] As a further improvement of this utility model: an injection pump is installed inside the injection tube, and the external shape of the shunt tube is "Y".

[0010] As a further improvement of this utility model: the diversion tube and the inlet tube are interconnected, and the injection tube is interconnected with the inlet tube through the diversion tube.

[0011] As a further improvement of this utility model: a locking block is fixedly installed on the back of the tweezers tip, and the tweezers tip forms an interlocking structure with the locking block and the disassembly groove.

[0012] As a further improvement of this utility model: the surface of the tweezers tip is provided with a flow groove, and the upper end of the flow groove is connected to the liquid inlet pipe.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Install an injection tube on the electrocautery forceps body. The lower end of the injection tube is connected to a shunt tube. Use the shunt tube to drip physiological saline onto the forceps tip. This changes the traditional dripping method. The lower end of the shunt tube is aligned with the forceps tip, so that the physiological saline can flow accurately to the forceps tip. This can effectively prevent the formation of eschar on the forceps tip and reduce adhesion.

[0015] 2. A circuit box is installed at the upper end of the electrocoagulation tweezers. The circuit and resistors in the circuit box are electrically connected to the tip of the electrocoagulation tweezers. The tip is equipped with a conductive tip. The conductivity of the conductive tip allows current to be used for electrocoagulation. A sliding switch is also provided to control the resistance in the circuit. When the switch is open, the resistance in the circuit decreases and the current increases. When the switch is closed, the resistance in the circuit increases and the current decreases. This adjustment method is simple and easy to implement, and it achieves intermittent electrocoagulation. Each electrocoagulation time is about 0.5 seconds, and it can be repeated multiple times until the electrocoagulation effect is achieved, avoiding overcoagulation. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides an anti-adhesion electrocoagulation forceps, comprising: an electrocoagulation forceps body 1, a disassembly groove 2 at the lower end of the electrocoagulation forceps body 1, and a forceps tip 4 installed inside the disassembly groove 2, a conductive tip 3 connected to the lower end of the forceps tip 4, an inlet tube 5 connected to the upper end of the forceps tip 4, a sliding switch 8 installed on the outer wall of the electrocoagulation forceps body 1, an injection tube 6 installed on the top of the electrocoagulation forceps body 1, and a shunt tube 7 connected to the lower end of the injection tube 6, power terminals 9 installed on both the left and right sides of the top of the electrocoagulation forceps body 1, and a power-connecting copper post 11 inserted inside the power terminal 9, a circuit box 14 installed on the upper end of the power-connecting copper post 11, and a resistor 16 electrically connected to the upper end of the circuit box 14, with a connecting piece 17 provided at one end of the resistor 16.

[0023] The resistor 16 is electrically connected to the circuit inside the circuit box 14. The energized copper post 11 is electrically connected to the tip 4 of the electrocautery tweezers body 1 through the energized terminal 9. The circuit box 14 is symmetrical about the center line of the electrocautery tweezers body 1, and a rotating shaft 15 is provided between the circuit boxes 14.

[0024] Specifically, resistor 16 is connected to wires via connecting piece 17, and is electrically connected to copper post 11 via wiring inside circuit box 14. Copper post 11 is plugged into terminal 9. In this way, conductive electrocoagulation is achieved through conductive tip 3 on tweezers tip 4. At the same time, a sliding switch 8 is electrically connected to the circuit. The opening and closing of sliding switch 8 is related to the value of resistor 16. When the switch is open, the resistance of 16 in the circuit decreases and the current increases. When the switch is closed, the resistance of 16 in the circuit increases and the current decreases, thereby achieving the effect of intermittent electrocoagulation. The setting of rotating shaft 15 allows the angle of electrocoagulation tweezers body 1 to change during clamping operation. The rotation structure between circuit box 14 and rotating shaft 15 can cooperate with electrocoagulation tweezers body 1 for clamping operation.

[0025] An infusion pump 10 is installed inside the injection tube 6. The external shape of the shunt tube 7 is "Y"-shaped and is connected to the inlet tube 5. The injection tube 6 is connected to the inlet tube 5 through the shunt tube 7. The infusion pump 10 pushes the saline solution inside the injection tube 6. The injection tube 6 and the shunt tube 7 are connected, and the saline solution is diverted to both sides of the electrocautery forceps through the shunt tube 7. The shunt tube 7 is connected to the inlet tube 5, and the saline solution enters the flow groove 13 on the inner wall of the forceps tip 4 along the inlet tube 5, dripping onto the forceps tip 4. This allows the saline solution to be accurately dripped onto the eschar location. Dripping the saline solution onto the electrocautery forceps can effectively prevent the formation of eschar on the forceps tip 4.

[0026] A locking block 12 is fixedly installed on the back of the tweezer tip 4. The tweezer tip 4 forms an interlocking structure with the disassembly groove 2 through the locking block 12. A flow groove 13 is provided on the surface of the tweezer tip 4, and the upper end of the flow groove 13 is connected to the liquid inlet pipe 5.

[0027] Specifically, the forceps tip 4 is fitted into the end of the electrocoagulation forceps body 1 by the locking block 12 and fixed with screws. The flow groove 13 on the surface of the forceps tip 4 is used for drainage, so that the saline can flow precisely to the forceps tip 4, avoiding drip deviation and adhesion.

[0028] The working principle of this utility model is as follows: When using this utility model, hold the electrocoagulation forceps body 1 and press the sliding switch 8 with your fingertip. While controlling the clamping operation of the forceps body 1 and the forceps tip 4, you can also control the sliding switch 8 to slide. The sliding switch 8 is turned on and off by sliding. When the sliding switch 8 is open, the resistance 16 in the circuit decreases and the current increases. When the switch is closed, the resistance 16 in the circuit increases and the current decreases, thereby achieving the effect of intermittent electrocoagulation. The forceps tip 4 is provided with a conductive tip 3. Utilizing the conductivity of the conductive tip 3, the conductive tip 3 can use the current to perform electrocoagulation. Each electrocoagulation time is about 0.5 seconds and can be repeated multiple times until the electrocoagulation effect is achieved, avoiding over-coagulation. The injection pump 10 pushes the physiological saline inside the injection tube 6. The physiological saline flows through the diversion tube 7 and the inlet tube 5 to the flow groove 13 on the inner wall of the forceps tip 4. The flow groove 13 flows the physiological saline to the forceps tip 4, and the physiological saline can be accurately dripped to the eschar location, effectively avoiding the formation of eschar on the forceps tip 4.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
