[0002] Vascular dissecting forceps are tools specifically designed for delicate surgical procedures, primarily used to carefully separate tissues, anatomical structures, and manage areas surrounding blood vessels. During surgery, vascular dissecting forceps not only block blood flow but also separate or clamp vascular tissue. Vascular dissecting forceps typically consist of a head, handles, and a grip, with two handles interlocking.

[0003] Currently, vascular dissection forceps are used in certain situations where it is necessary to pry open or separate the membrane or other soft tissue surrounding blood vessels to better expose the surgical field or perform other necessary operations. However, existing forceps heads typically have fine tips, which can easily cause damage to the vascular membrane or other soft tissues during operation, leading to numerous inconveniences in surgical procedures. Furthermore, after the forceps head has clamped, slight hand tremors can cause the forceps head to fail to clamp tightly, affecting the surgeon's ability to perform the procedure. Therefore, improvements and developments are needed to address these issues. Utility Model Content

Any modifications to the structure, changes in the proportions, or adjustments to the size, without affecting the effects and purposes that the present invention can produce, should still fall within the scope of the technical content disclosed in the present invention.

[0018] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0019] Example 1, combined with Figures 1 to 6 As shown, this embodiment provides a medical surgical forceps, including a first forceps body 1, a second forceps body 2 that is cross-hinged with the first forceps body 1, and forceps heads respectively disposed at the heads of the first forceps body 1 and the second forceps body 2. A needle body 9 is disposed on one of the forceps heads, and the needle body 9 is locked to the forceps head by a locking member 7 to achieve a detachable connection with the forceps head. The needle body 9 is curved upwards clockwise or upwards counterclockwise relative to the forceps head, and has a needle tip 905 disposed on one free end of the needle body 9. The arc-shaped needle body 9 design allows the needle body 9 to pass through tissue more easily, reducing damage to surrounding blood vessels and improving operational accuracy. Furthermore, the arc-shaped needle body 9 makes it easier to control the direction and insertion angle of the needle body 9, improving operational efficiency.

[0020] For example, the forceps head includes a first forceps head 8 disposed on the second forceps body 2 and a second forceps head 10 disposed on the first forceps body 1. The needle body 9 is detachably connected to the first forceps head 8 through a locking member 7. The needle body 9 has an arc-shaped structure that bends clockwise upward relative to the first forceps head 8. When operating the vascular dissection forceps, medical personnel can use the arc-shaped needle body 9 to pry open or separate the membrane or other soft tissue around the blood vessel, so as to more clearly expose the surgical field or perform other necessary operations. In addition, the arc-shaped needle body 9 makes it easier to control the direction and insertion angle of the needle body 9, thereby improving the efficiency of operation.

[0021] Specifically, a spring 6 is provided between the first clamp 1 and the second clamp 2. The spring 6 is used to provide appropriate resistance when the first clamp 1 and the second clamp 2 are closed, which helps to increase the precise control of the first clamp 1 and the second clamp 2 and makes the operation easier.

[0022] For example, both the first clamp body 1 and the second clamp body 2 are provided with an operating ring 4 and a clamping block 5 at their tails. The clamping block 5 is located on the opposite side of the first clamp body 1 and the second clamp body 2. The contact surface of the two clamping blocks 5 is made of soft rubber material, which can be medical grade silicone. When the first clamp body 1 and the second clamp body 2 are closed, the clamping block 5 can play a role in silencing, thereby reducing the noise during operation. The operating ring 4 is located on the opposite side of the first clamp body 1 and the second clamp body 2, which makes it convenient for medical staff to hold the operating ring 4.

[0023] For example, the needle tip 905 is spherical and is positioned on the needle body 9 in the opposite direction to the other clamp head. The spherical design of the needle tip 905 prevents damage to the membrane or other soft tissue around the blood vessel when the needle body 9 is used to pry open or separate the membrane or other soft tissue around the blood vessel.

[0024] Specifically, the mounting structure of the needle body 9 and the forceps head is as follows: the forceps head has a sleeve hole 802 corresponding to the needle body 9, and the needle body 9 is sleeved in the sleeve hole 802. The forceps head also has a mounting hole, which is perpendicular to and communicates with the sleeve hole 802. The needle body 9 is inserted into the sleeve hole 802, and the locking member 7 cooperates with the mounting hole and abuts against the needle body 9, so that the needle body 9 is confined in the sleeve hole 802. The sleeve hole 802 is set on the first forceps head 8 along the horizontal direction of the vascular dissection forceps. The mounting hole is perpendicular to the sleeve hole 802 and communicates with the sleeve hole 802 and the outside. The locking member 7 cooperates with the mounting hole and abuts against the needle body 9 to realize the detachable connection of the needle body 9, thereby facilitating the replacement of needle bodies 9 with different curvatures to suit different surgical operations.

[0025] Specifically, the detachable connection between the needle body 9 and the first pliers head 8 is achieved through a locking member 7. The locking member 7 includes a locking screw 702, and the mounting hole is provided with a thread 805 corresponding to the locking screw 702. After the locking screw 702 is threadedly engaged with the thread 805, the free end of the locking screw 702 abuts against the needle body 9. During connection, the needle body 9 is inserted into the sleeve hole 802, and the locking screw 702 is inserted into the mounting hole and screwed with the thread 805. At this time, the rod end of the locking screw 702 abuts against the needle body 9, thereby confining the needle body 9 within the sleeve hole 802, thus achieving a detachable connection between the needle body 9 and the first pliers head 8.

[0026] For example, to facilitate operation by gripping the locking screw 702, a ball 701 is provided on the locking screw 702. The pliers head has a groove 801 corresponding to the mounting hole. The groove 801 is stepped, and there is a certain gap between the groove 801 and the ball 701. When using the locking member 7 to lock the needle 9, the ball 701 is gripped and rotated to drive the locking screw 702 to rotate, so that the locking screw 702 is screwed into the thread 805. The gap between the groove 801 and the ball 701 transitions with the arc of the top surface of the first pliers head 8. When the locking screw 702 is screwed to the bottom end of the thread 805, it is convenient for medical personnel to grip the ball 701.

[0027] Preferably, an elastic element is provided within the groove 801. The elastic element is sleeved on the locking screw 702, and its two ends abut against the ball 701 and the groove 801, respectively. The elastic element can be a locking pressure spring 703, with its two ends connected to the bottom of the groove 801 and the ball 701, respectively. Through the elastic force of the locking pressure spring 703, the connection between the locking screw 702 and the thread 805 is made more stable.

[0028] Specifically, the pliers head is provided with a limiting hole 803 communicating with the sleeve hole 802. The needle body 9 is disposed in a limiting ring 904 corresponding to the limiting hole 803. The limiting ring 904 is inserted into the limiting hole 803. A limiting plane 804 is formed on the limiting hole 803. A fitting plane 902 that matches the shape of the limiting plane 804 is formed on the limiting ring 904. When the fitting plane 902 and the limiting plane 804 are in contact, the needle body 9 is limited in its axial direction. When the fitting plane 902 and the limiting plane 804 cooperate, the relative rotation between the needle body 9 and the first pliers head 8 can be avoided, improving the reliability and accuracy of the needle body 9 during operation.

[0029] For example, the needle body 9 has a threading hole 903 for a suture to pass through, and the threading hole 903 is located on the other free end of the needle body 9. Before the vascular dissection forceps is used, the suture can be introduced through the threading hole 903. During the operation, the suture moves with the needle body 9, which can achieve the operation of vascular ligation.

[0030] For example, one of the clamp heads is provided with a clearance groove 1001. When the first clamp body 1 and the second clamp body 2 are closed, the clearance groove 1001 is used to accommodate the needle body 9. The clearance groove 1001 is provided on the second clamp head 10. When the first clamp body 1 and the second clamp body 2 are closed, the tail end of the needle body 9 is located in the clearance groove 1001, thereby preventing the needle body 9 from blocking the second clamp head 10 and causing the first clamp body 1 and the second clamp body 2 to be unable to close.

[0031] Specifically, it also includes auxiliary guide components disposed on the first clamp body 1 and the second clamp body 2. The auxiliary guide components include a guide rod 11 and a guide groove 201. The guide rod 11 is slidably disposed in the guide groove 201. Both the guide rod 11 and the guide groove 201 are provided with mutually cooperating friction protrusions 1101. When the first clamp body 1 and the second clamp body 2 are closed, the friction protrusions 1101 of the guide rod 11 are engaged with the friction protrusions 1101 of the guide groove 201. A spring 6 is sleeved on the guide rod 11. The shape of the guide rod 11 is set to the opening or closing trajectory of the first clamp body 1 and the second clamp body 2. When the first clamp body 1 and the second clamp body 2 are open or closed, the guide rod 11 slides along the guide groove 201, which can prevent the first clamp body 1 and the second clamp body 2 from being misaligned. In addition, the friction protrusion 1101 is toothed, and the friction protrusion 1101 of the guide rod 11 cooperates with the friction protrusion 1101 of the guide groove 201 so that the first clamp body 1 and the second clamp body 2 can be locked when closed, thereby ensuring the reliability of the vascular separation forceps operation.

[0032] The working principle of this utility model is as follows: When medical personnel connect the needle body 9 and the first clamp head 8 through the locking member 7 to achieve the locking operation, the medical personnel hold the ball 701 and rotate it to drive the locking screw 702 to rotate, so that the locking screw 702 is screwed into the thread 805. The rod end of the locking screw 702 abuts against the needle body 9, thereby confining the needle body 9 within the sleeve hole 802. Then, the suture is introduced into the thread hole 903. In actual operation, the medical personnel hold the operating ring 4, find a suitable position, and use the needle tip 905 of the needle body 9 to open or separate the vascular membrane or other soft tissue to achieve the operation. Due to the arc-shaped design of the needle body 9, it is easier to control the direction and insertion angle of the needle body 9, thereby improving the operation efficiency. When vascular ligation is required, the suture is wrapped around the part of the blood vessel blocked by the vascular separation clamp, knotted and fixed to confirm the ligation effect.

[0033] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
