Description

Technical Field

[0001] This utility model relates to the field of surgical instruments technology, specifically to a surgical excision device. Background Technology

[0002] Uterine fibroids are mainly formed by the proliferation of uterine smooth muscle cells, with a small amount of fibrous connective tissue present as a supporting tissue. Therefore, the term uterine leiomyoma is more accurate; or simply uterine fibroid. A myoma dissector is a commonly used tool in uterine fibroid removal surgery, which is usually a combination of tumor clips and a blade.

[0003] The current removal process requires the use of surgical scissors to cut the tumor and then forceps to remove the tumor mass. This requires changing multiple surgical instruments, making the operation cumbersome and increasing the operation time. Furthermore, excessive force applied by the hand during the forceps removal process can easily cause the tumor to rupture, leading to secondary infection for the patient, thus making it impractical.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] See Figures 1-3 As shown, this utility model provides a surgical excision device, including a handle 1. The front end of the handle 1 is provided with an L-shaped groove 2. Two cutting blades 3 are rotatably connected to the bottom surface of the L-shaped groove 2. The bottom surface of the L-shaped groove 2 is provided with an elastic structure for driving the two cutting blades 3 to open. The upper surface of the handle 1 is provided with a push plate 4 for driving the two cutting blades 3 to close together. The upper surfaces of the two cutting blades 3 are rotatably connected with support arms 5 along their length direction. The ends of the two support arms 5 are fixedly connected with gripping spoons 6. The surfaces of the two cutting blades 3 are provided with a fixing structure for fixing the rotation position of the support arms 5.

[0023] As an optional implementation, the elastic structure includes two elastic ropes 7. The two ends of the elastic ropes 7 are fixedly connected to the shearing blade 3 and the L-shaped groove 2, respectively. The two elastic ropes 7 are distributed in a figure-eight shape, and can automatically open by their own elasticity when the shearing blade 3 is not under force, so as to facilitate the next shearing action.

[0024] As an optional implementation, a gate-shaped plate 401 is fixedly connected to the end of the push plate 4. Limiting blocks 402 are fixedly connected to both ends of the lower side of the gate-shaped plate 401. Sloping extrusion strips 405 that wedge with the limiting blocks 402 are fixedly connected to the outer sides of the two shearing blades 3. The L-shaped groove 2 and the handle 1 are provided with sliding connectors for moving the limiting blocks 402 and the push plate 4. The push plate 4 can be pushed forward to drive the gate-shaped plate 401 and the two limiting blocks 402 to move toward the tip of the shearing blades 3. At the same time, the two limiting blocks 402 wedge with the sloping extrusion strips 405 to drive the two shearing blades 3 to move closer to each other and cut off the tumor.

[0025] Reference Figure 2As shown, the sliding connector includes a T-shaped slider 403 fixedly connected to the bottom surface of the push plate 4 and the two limit blocks 402. The surfaces of the L-shaped groove 2 and the handle 1 are provided with T-shaped grooves 404 that are slidably connected to the T-shaped slider 403, which can make the push plate 4 more stable when pushing the limit blocks 402 to move and avoid shaking.

[0026] Reference Figure 3 As shown, the tip of the shearing blade 3 is designed to curve upwards, and a T-shaped circular plate 8 is fixedly connected to the bottom surface of the shearing blade 3. T-shaped arc grooves 9 that fit and fit the T-shaped circular plate 8 are opened on both sides of the surface of the L-shaped groove 2. The upward-curved shearing blade 3 can easily cut tumor blocks at various angles. At the same time, the sliding connection of the T-shaped circular plate 8 in the T-shaped arc groove 9 can make the two shearing blades 3 more stable when rotating laterally.

[0027] Furthermore, the grasping spoon 6 includes an arc-shaped plate 601 fixedly connected to the end of the support arm 5. An elastic membrane 602 is fixedly connected to one side of the arc-shaped plate 601. The arc-shaped plate 601 can ensure the degree of closure of the bottom side of the grasping spoon 6 and provide hardness to the bottom side of the grasping spoon 6. At the same time, the elastic membrane 602 can elastically wrap the tumor mass of appropriate size and improve the grasping effect.

[0028] As an optional implementation, the fixing structure includes a column 12 fixedly connected to one side of the tail end of the upper surface of the shearing blade 3. Magnetic plates 13 are fixedly connected to the upper ends of both columns 12, and the magnetic plates 13 are magnetically connected to the iron support arm 5. A locking hole 11 is opened on one side of the tip of the shearing blade 3. A locking rod 10 is fixedly connected to the support arm 5 and engages with the locking hole 11. When the shearing function is needed, the support arm 5 is rotated 180 degrees, and the magnetic force of the magnetic plate 13 can attract and fix the support arm 5, ensuring smooth operation of the two shearing blades 3. When the gripping function is needed, the two support arms 5 are flipped 180 degrees, so that the gripping spoon 6 is located at the tip of the shearing blade 3. At this time, the locking rod 10 engages in the locking hole 11, completing the flipping and fixing of the support arm 5. At this time, the two gripping spoons 6 can be opened and closed by opening and closing the shearing blade 3, facilitating the removal of tumor masses.

[0029] The working principle of this utility model:

[0030] In use, the two shear blades 3 automatically open under the action of the elastic structure, and at the same time cooperate with the limiting blocks 402 on both sides to form a suitable opening angle. Then, the shear blades 3 are inserted into the body to the cutting site. The push plate 4 is pushed forward to drive the gate plate 401 and the two limiting blocks 402 to move towards the tip of the shear blades 3. At the same time, the two limiting blocks 402 cooperate with the wedge-shaped extrusion strip 405 to drive the two shear blades 3 to move closer to each other and cut off the tumor. Then, the shear blades 3 are removed, and the two support arms 5 are flipped so that the two gripping spoons 6 are fixed to the tip of the shear blades 3 by the fixing structure. Then, the shear blades are inserted into the body again, and the opening and closing of the shear blades 3 drives the two gripping spoons 6 to open and close, so that the tumor is grabbed into the gripping spoons 6 and removed.

[0031] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
