Description

Technical Field

[0001] The invention belongs to the field of medical equipment, in particular to a rotatable hemostatic forceps based on bipolar electrocoagulation and mechanical clamping. Background Art

[0002] Bipolar electrocoagulation forceps are a commonly used instrument in minimally invasive gynecological and obstetric surgery. They generate current between two electrodes, causing ions in the clamped tissue to vibrate and generate heat, thereby sealing blood vessels and coagulating tissue to stop bleeding. The mechanical clamping action of the forceps head also helps control bleeding points.

[0003] However, the existing bipolar coagulation forceps are usually designed with a fixed angle, or have only limited angle adjustment functions, which cannot meet the complex and changeable surgical field of view requirements in minimally invasive gynecological and obstetric surgery. Doctors often need to frequently adjust the position of the instrument or even change the patient's position, which increases the difficulty and time cost of the surgical operation. It is difficult to achieve accurate blood vessel clamping, which may lead to increased intraoperative bleeding. In addition, doctors need to spend more energy to control the position and angle of the forceps during the operation, which can easily lead to hand fatigue, thereby affecting the stability and accuracy of the operation, reducing the overall convenience of using bipolar coagulation forceps, and having a certain impact on the overall use efficiency of bipolar coagulation forceps.

[0017] 1. The present invention provides a rotatable clamp rod and a guide assembly for adjusting the rotation angle of the No. 1 support shaft. During surgery, the doctor can quickly and easily adjust the angle of the clamp head according to the needs of different surgical fields. In minimally invasive gynecological and obstetric surgeries, the clamp head can be accurately directed to the bleeding site by rotating the clamp rod and adjusting the No. 1 support shaft. There is no need to frequently adjust the position of the instrument or change the patient's position. This greatly reduces the difficulty of surgical operation, reduces the time cost of surgery, and improves the accuracy of vascular clamping, thereby effectively reducing the amount of intraoperative bleeding.

[0018] 2. The present invention utilizes a position-limiting structure, including a fixed ratchet, a movable ratchet, and a tension spring, to reliably control the rotation angle of the forceps rod. When the forceps rod is rotated to the appropriate angle, the ratchet teeth of the movable ratchet engage with the fixed ratchet, maintaining a stable locking state under the action of the tension spring. This prevents unnecessary rotation of the forceps rod due to external forces or hand shaking during the surgical operation, ensuring operational stability and precision, reducing the surgeon's energy consumption in controlling the position and angle of the forceps heads, and avoiding operational errors due to hand fatigue.

[0019] 3. This invention utilizes a temperature sensor on the clamping surface of the forceps tip, coupled with the connection between the grip handle and an external high-powered electric knife unit, and a temperature display unit on the unit, to monitor the coagulation temperature in real time. During surgery, the surgeon can visually observe the temperature at the forceps tip, preventing excessive coagulation and carbonization of tissue, thereby better protecting patient tissue and improving surgical safety and effectiveness.

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] As attached Figure 1 To the attached Figure 6 As shown:

[0030] Embodiment 1: The present invention provides a rotatable hemostatic forceps based on bipolar coagulation and mechanical clamping, comprising a gripping handle 1, a connector 2 fixedly mounted on one side of the gripping handle 1, an electrocoagulation switch 10 provided on the upper surface of the connector 2, a clamp rod 3 rotatably mounted on one side of the connector 2, a fixing groove 4 provided on one side of the clamp rod 3, a first support shaft 5 rotatably mounted on one side of the inner wall of the fixing groove 4, and a clamping mechanism provided on the outer surface of the first support shaft 5 for applying to a bleeding site to stop bleeding;

[0031] The outer surface of the clamp rod 3 is also provided with a limiting structure for controlling the rotation angle of the clamp rod 3;

[0032] The limiting mechanism includes a fixed ratchet 17, which is fixedly mounted on one side of the connecting head 2 near the hinge position of the clamp rod 3, and a fixed baffle 18 is fixedly mounted on one edge of the outer surface of the clamp rod 3. A movable ratchet 19 is sleeved on the outer surface of the clamp rod 3 between the fixed ratchet 17 and the fixed baffle 18, and a spline hole is provided through the middle of one side of the movable ratchet 19. The outer surface of the clamp rod 3 is placed between the fixed ratchet 17 and the fixed baffle 18 to form a spline shaft, and the spline shaft and the spline hole are embedded with each other. Ratchets are fixed at the docking position on one side of the fixed ratchet 17 and the movable ratchet 19, and the ratchet teeth between the fixed ratchet 17 and the movable ratchet 19 are engaged with each other. The outer surface of the clamp rod 3 is placed between the fixed baffle 18 and the movable ratchet 19 and is sleeved with a tension spring 20. A guide assembly is also provided inside the clamp rod 3 to adjust the rotation angle of the No. 1 support shaft 5;

[0033] The guide assembly includes a fixed inner cavity 21, which is opened at an edge of one side inside the clamp rod 3. A connecting shaft 22 is rotatably mounted at the front and rear ends of the inner wall of the fixed inner cavity 21. A second elastic steel wire rope 24 is fixedly connected to one side of the outer surface of the connecting shaft 22. A second rope hole 25 is opened at a middle position of the clamp rod 3 on one side of the inner wall of the fixed inner cavity 21. One side of the second elastic steel wire rope 24 passes through the second rope hole 25 and is wrapped around the outer surface of the first support shaft 5, and one side edge of the second elastic steel wire rope 24 is fixedly connected to the first support shaft 5.

[0034] A positioning assembly is also provided on the outside of the clamp rod 3 for limiting and fixing the connecting shaft 22 .

[0035] As can be seen from the above, before surgery, the staff must first check whether all components of the hemostat are normal, ensure that the tension spring 20 has good elasticity, and that the ratchet teeth of the movable ratchet 19 and the fixed ratchet 17 are not damaged. Then, during surgery, when the angle of the clamp rod 3 needs to be adjusted, the staff will hold the clamp rod 3 by hand and rotate the clamp rod 3 against the elastic force of the tension spring 20. Since the movable ratchet 19 and the clamp rod 3 are interlocked through the spline shaft and spline hole, the movable ratchet 19 will rotate with the clamp rod 3. During the rotation process, the movable ratchet 19 interacts with the ratchet teeth of the fixed ratchet 17. There will be a slight click every time the ratchet teeth are rotated, which facilitates the staff to accurately control the angle. When the pliers rod 3 is rotated to a suitable angle, under the elastic force of the tension spring 20, the movable ratchet 19 is tightly engaged with the fixed ratchet 17, stably locking the pliers rod 3 at this angle; then, when it is necessary to adjust the rotation angle of the No. 1 support shaft 5, the staff turns the knob 23, and the knob 23 drives the connecting shaft 22 to rotate. When the connecting shaft 22 rotates, the second elastic steel wire rope 24 wrapped thereon will pull the No. 1 support shaft 5, causing the pliers head 9 to rotate around the No. 1 support shaft 5, thereby realizing precise adjustment of the angle of the pliers head 9 to better fit the bleeding area.

[0036] Example 2:

[0037] Refer to the attached Figure 3 To the attached Figure 5The clamping mechanism includes an adjusting support plate 6, which is symmetrically fixed to the outer edge of the No. 1 support shaft 5, and a No. 2 support shaft 7 is installed between the two adjusting support plates 6 near the edge. The outer surface of the No. 2 support shaft 7 is symmetrically rotatably installed with a movable part 8, and a pliers head 9 is fixedly installed on one side of the movable part 8. A groove 11 is provided on one side of the gripping handle 1, and a movable handle 12 is rotatably installed inside the groove 11 through a bearing. A connecting plate 13 is hinged on the top of one side of the movable handle 12, and a first elastic steel wire rope 16 is symmetrically fixed to one side of the connecting plate 13. The top of one side of the inner wall of the groove 11 extends to the connector 2 and is provided with an inner groove 14. One side of the inner wall of the inner groove 14 passes through the upper and lower ends of the clamp rod 3 and is provided with a No. 1 rope hole 15. One side of the first elastic steel wire rope 16 passes through the No. 1 rope hole 15 and is fixed to the edge of one side of the movable part 8. A circular hole is provided at one side opening of the inner groove 14, and one side of the outer surface of the two first elastic steel wire ropes 16 is located in the circular hole, and the first elastic steel wire rope 16 and the circular hole adapt to each other.

[0038] As can be seen from the above, first, during surgery, when clamping a bleeding area is required, the staff member pinches the movable handle 12 with their hands, causing the movable handle 12 to rotate around its bearing in the groove 11, driving the first elastic steel wire 16 to move through the connecting plate 13. Since the first elastic steel wire 16 passes through the No. 1 rope hole 15 and is fixed to a side edge of the movable member 8, the movement of the first elastic steel wire 16 pulls the movable member 8 to rotate around the No. 2 support shaft 7, thereby closing the forceps head 9 and achieving mechanical clamping of the bleeding area. During this process, the transmission of the elastic steel wire ensures flexibility and stability of the operation, enabling the clamping action to be achieved quickly and accurately.

[0039] Reference Figure 4 The clamping surface at one end of the pliers head 9 is provided with several temperature sensing parts 29, and the outer surface of the gripping handle 1 is connected to the external high-distribution electric knife host through a wire, and the high-distribution electric knife host is provided with a temperature display unit to monitor the electrocoagulation temperature in real time.

[0040] As can be seen above, during electrocoagulation hemostasis, the temperature sensor 29 senses the temperature of the contact area between the forceps head 9 and the tissue in real time and transmits the temperature signal to the high-powered electric knife main unit. The temperature display unit on the main unit displays the temperature value in real time, allowing the doctor to adjust the electrocoagulation parameters in a timely manner according to the temperature. If the temperature is too high, the doctor can reduce the electrocoagulation power or shorten the coagulation time to avoid excessive coagulation and tissue carbonization, thereby protecting the patient's tissue.

[0041] Example 3:

[0042] Reference Figure 5The positioning assembly includes a limit block 26, which is fixedly mounted at one end of the connecting shaft 22 and extends to the outside of the clamp rod 3. The other end of the connecting shaft 22 extends to the outside of the clamp rod 3 and is equipped with a knob 23. A support plate 27 is fixedly mounted on the outer surface of the clamp rod 3 near the limit block 26. The top of one end of the support plate 27 is threadedly connected to a limit bolt 28, and one end of the limit bolt 28 abuts against the limit block 26.

[0043] As can be seen from the above, first, after the staff adjusts the connecting shaft 22 by turning the knob 23 and completes the adjustment of the rotation angle of the No. 1 support shaft 5, it is necessary to fix the position of the connecting shaft 22. At this time, the staff tightens the limit bolt 28 so that one end of the limit bolt 28 is tightly against the limit block 26. In this way, the rotation of the connecting shaft 22 is limited to ensure that during the surgical operation, the connecting shaft 22 will not rotate due to external forces or vibrations, thereby ensuring the stability of the forceps head 9 after the angle is adjusted, and providing reliable protection for precise hemostasis operations.

[0044] Working principle: During surgery, when the doctor adjusts the angle of the forceps rod 3 to suit the surgical field of view according to actual needs, he or she grasps the forceps rod 3 to overcome the elastic force of the tension spring 20, causing it to rotate around the hinge with the connector 2. The movable ratchet 19 rotates synchronously due to its engagement with the spline shaft of the forceps rod 3. It interacts with the ratchet teeth of the fixed ratchet 17 to provide feedback on the angle change. Once in place, the tension spring 20 pushes the movable ratchet 19 to engage with the fixed ratchet 17, locking the forceps rod 3.

[0045] When the angle of the forceps head 9 needs to be adjusted to fit the bleeding area, the knob 23 is turned to drive the connecting shaft 22 to rotate in the fixed inner cavity 21, so that the second elastic steel wire rope 24 fixed to the outer surface of the connecting shaft 22 is wound or released, and the first support shaft 5 is pulled through the second rope hole 25, so that the forceps head 9 can be accurately rotated around the first support shaft 5;

[0046] When clamping the bleeding area, pinch the movable handle 12 to make it rotate around the bearing in the groove 11, and drive the first elastic wire rope 16 through the connecting plate 13, pulling the movable part 8 to rotate around the second support shaft 7, prompting the clamp head 9 to close, completing the mechanical clamping and auxiliary hemostasis;

[0047] When electrocoagulation stops bleeding, the electrocoagulation switch 10 is pressed, and the current is transmitted to the clamp head 9, causing the ions in the clamped tissue to oscillate and generate heat to achieve hemostasis; at the same time, the temperature sensor 29 on the clamping surface of the clamp head 9 monitors the temperature in real time and transmits it to the external high-distribution electric knife host. The doctor adjusts the electrocoagulation parameters in time according to the value of the host temperature display unit to avoid tissue carbonization.

[0048] The embodiments of the present invention are provided for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
