Description

Technical Field

[0001] The present application relates to the technical field of surgical instruments, and in particular to a bipolar blood vessel sealing surgical instrument. Background Art

[0002] Bipolar vascular closure surgical instruments are a type of high-frequency surgical equipment widely used in the field of surgery, mainly consisting of bipolar instruments and energy generators. Its working principle is to generate high heat through the current between the bipolar electrodes, denaturing the collagen and elastin on the blood vessel wall, thereby coagulating and closing the blood vessel to achieve the effect of hemostasis.

[0003] After searching, the Chinese patent announcement number CN118634025A discloses a bipolar blood vessel closure device. Although the device realizes the circumferential rotation of the jaw assembly around the axis of the outer tube or the inner tube and the lateral bending relative to the axis of the outer tube or the inner tube by setting a bending member, a bending drive assembly and a rotating drive assembly, so that the jaw assembly has a wider operating field during surgery, and there is no need to re-open holes in other positions, which improves the efficiency of surgery and reduces the risk of secondary trauma. However, the device cannot adjust the size of the electrode clamping surface according to actual use during use. During the operation, the blood vessels in different parts are of different thicknesses, and the required clamping force and contact area are also different. If the size of the electrode clamping surface is fixed, for thinner blood vessels, the blood vessels may be unevenly stressed due to the clamping surface being too large, resulting in clamping or incomplete cutting; for thicker blood vessels, if the clamping surface is too small, they may not be effectively closed, affecting the surgical effect;

[0004] In addition, existing bipolar vascular closure devices have a significant limitation in their design, namely, the angle between the chuck and the handle is fixed and cannot be adjusted. This means that during surgery, doctors cannot flexibly adjust the angle between the chuck and the handle according to different surgical sites and operation requirements to achieve the best operating posture and field of view. This fixed angle setting may cause doctors to constantly adjust their operating postures in certain complex surgical scenarios, and may even need to frequently change instruments, thereby increasing the complexity and time cost of the operation, and may also increase the surgical risks for patients.

This design enables the action of the control mechanism to be stably and accurately transmitted to the clamping mechanism, ensuring that the opening and closing action of the jaws is smooth and reliable.

[0011] Preferably, the second connecting rod passes through the interior of the clamping block, and a butt joint is welded to the other end of the second connecting rod, the butt joint is sleeved on the outside of the connector, and the connector and the butt joint are rotatably connected to each other, the clamping block is made of insulating material, and a groove is provided on the inner side of one end of the clamping block, the grooves on the inner side of the clamping block are distributed in an arc shape with equal spacing, and a butt joint is welded to the other end of the second connecting rod, the butt joint is sleeved on the outside of the connector, and the two are rotatably connected. This design enables the action of the control mechanism to be stably transmitted to the clamping mechanism through the connector and the butt joint, ensuring smooth and reliable opening and closing of the jaws. The clamping block is made of insulating material, which can effectively prevent current leakage and ensure electrical safety during surgery. This is particularly important for bipolar vascular closure surgical instruments, because the electrode mechanism will generate high heat and current when working, and the insulating material can prevent the current from causing damage to surrounding tissues and doctors.

[0012] Preferably, the electrode mechanism includes an electrode plate, two of which are provided, and the two electrode plates are respectively connected to the ends of the two clamping plates through a connecting shaft, the surface of the clamping plate is provided with a hole groove, and the inside of the hole groove is a threaded structure, the hole groove on the surface of the clamping plate is threadedly connected to a conductive screw, and the other end of the conductive screw is fitted with a conductive block, and the conductive block is provided with two, and the two conductive blocks are embedded in the surface of the clamping plate, and the electrode blocks are embedded at both ends of the electrode plate, and the surface of the clamping plate is provided with a threaded hole groove, and the conductive screw is fixed in the hole groove by a threaded connection, and the other end is fitted with the conductive block, ensuring that the current can be stably transferred from the wire through the conductive screw to the conductive block, and then transferred to the electrode block through the electrode plate, and finally applied to the blood vessel.

The flexible adjustment function of the electrode plate allows the doctor to quickly adjust the angle of the electrode plate according to different surgical sites and blood vessel thicknesses, without the need to frequently change instruments, thereby improving the efficiency and convenience of the operation. This design reduces the adjustment time and operation complexity during surgery, and reduces the surgical risk of the patient.

[0013] Preferably, the surface of the conductive block has an arc-shaped structure, and the conductive block is embedded in the interior of the positioning hole, the internal shape of the positioning hole is consistent with the shape of the conductive block, the electrode plate is made of insulating material, and copper wire is embedded in the electrode plate, the electrode blocks at both ends of the electrode plate are electrically connected to each other through the copper wire, and the surface of the conductive block has an arc-shaped structure, which is consistent with the internal shape of the positioning hole, ensuring that the conductive block can be accurately embedded in the positioning hole, thereby fixing the position of the electrode plate, and precise positioning enables the electrode plate to remain stable during operation, ensuring that current can be accurately applied to the blood vessel, thereby improving the hemostatic effect.

[0014] Preferably, the two ends of the electrode plate are one large and one small, and the ends of the electrode plate have a smooth surface. The surface of the electrode block at the end of the electrode plate is provided with a strip-shaped protrusion-like structure, and the strip-shaped protrusion-like structures are distributed in a straight line with equal spacing.

For thinner blood vessels, a smaller electrode plate end can be used to avoid clamping the blood vessels; for thicker blood vessels, a larger electrode plate end can be used to ensure effective closure of the blood vessels, thereby improving the adaptability and flexibility of the instrument and being suitable for different surgical scenarios. The end of the electrode plate has a smooth surface, which can reduce the friction and pressure concentration when the electrode plate contacts the blood vessel, and prevent the blood vessel from being damaged during the clamping process. The smooth surface helps to evenly distribute pressure, protect vascular tissue, and improve the safety of the operation. The surface of the electrode block is provided with a strip-shaped protrusion-like structure, and the strip-shaped protrusions are distributed in a straight line with equal spacing.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] (1) When the device is used, the two electrode plates of the electrode mechanism are moved to the outside of the blood vessel, and the first handle and the second handle are pinched. The first handle pulls the connecting rod through the first connecting rod and the second connecting rod, and the connecting rod drives the two clamping plates, so that the clamping plates drive the electrode plates to clamp the blood vessel. The current is transmitted through the conductive blocks at the ends of the electrode plates. The current between the bipolar electrodes generates high heat, causing the collagen and elastin in the blood vessel wall to denature, and the blood vessel coagulates and closes to stop bleeding. When it is necessary to switch the clamping head, the two electrode plates are bent and rotated to disengage the positioning holes at the ends of the electrode plates from the conductive blocks. The electrode plates can be rotated 180 degrees, and the positioning holes at the other end are engaged with the conductive blocks at a fixed angle. Because the two ends of the electrode plates are of different sizes, the heads can be switched according to the thickness of the blood vessels, thereby improving the adjustability of the device.

[0017] (2) Since one end of the first handle and the rod body are rotatably connected, and the end of the first connecting rod and the end of the second connecting rod are also rotatably connected, when the angle between the first electrode plate and the second electrode plate is fixed, the handle can be rotated by holding the rod body, so that the angle of the handle can be adjusted arbitrarily, so that the handle can be adjusted to a suitable angle for operation without affecting the use of the device, thereby greatly improving the convenience of using the device.

[0018] (3) By arranging a spring between the first handle and the second handle, when the first handle and the second handle are pinched together, the other end of the device can clamp the blood vessel. When the first handle and the second handle are released, the first handle and the second handle can be quickly separated under the action of the spring, so that the other end of the device can quickly release the clamping of the blood vessel, which is helpful to avoid the other end of the device clamping the blood vessel for too long, causing damage to the blood vessel, and thus helps to improve the flexibility of the device when used.

[0019] (4) By turning the second adjusting knob, the second adjusting knob can compress the spring, thereby adjusting the spring pressure, which is beneficial to further improve the adjustability of the device. When the device clamps the blood vessel without power, by turning the first adjusting knob, the first adjusting knob can move along the thread of the outer wall of the adjusting rod, thereby locking the angle between the first handle and the second handle, so that the other end of the device can maintain the clamping state for a long time, which is beneficial to avoid hand fatigue caused by the operator pinching the first handle and the second handle for a long time, and thus is beneficial to improve the convenience of using the device.
