[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Example, see Figures 1 to 8 A retriever for gynecological abdominal surgery, the retriever body consists of a manipulation end, a retriever end and a cutting end, the cutting end includes a cutting seat 1, a receiving groove 2 is opened at the end of the cutting seat 1, and a scalpel 3 is connected to the inner wall of the receiving groove 2 through a telescopic receiving piece; further, the telescopic receiving piece includes a connecting end seat 14 slidably arranged in the receiving groove 2, the scalpel 3 is fixedly arranged on the connecting end seat 14, and the connecting end seat 14 is connected to the inner wall of the receiving groove 2 through a reset spring.

[0032] During gynecological abdominal surgery, the surgical process is carried out through the scalpel 3. When the surgical cutting is completed, the scalpel 3 can be stored, and the diseased tissue after the surgical cutting can be removed through the object-removing end. Compared with traditional surgery, this can reduce the number of operating holes opened in the abdominal cavity and reduce damage to the human body.

[0033] The picking end includes an extension column 4, the end of the extension column 4 is fixedly connected to an electromagnetic seat 6, the end of the cutting seat 1 is connected to a permanent magnet seat 7, and limiting rings 5 ​​are provided at the opposite ends of the electromagnetic seat 6 and the permanent magnet seat 7. The permanent magnet seat 7 and the limiting ring 5 are connected by a plurality of elastic picking cage bars 8. Furthermore, universal connecting balls 15 are provided at both ends of the elastic picking cage bars 8, and the universal connecting balls 15 are rotatably connected to a ball seat 16, and the ball seat 16 is connected to the limiting ring 5.

[0034] It should be noted that the electromagnetic seat 6 and the permanent magnet seat 7 are magnetically attracted to each other, and the magnetic force of the electromagnetic seat 6 follows the size of the current, and can flexibly adjust the size of the magnetic force, thereby controlling the size of the magnetic attraction between the permanent magnet seat 7, thereby satisfying the adjustment of the bending degree of the elastic collection cage bar 8 arranged therebetween. By changing the bending degree of the elastic collection cage bar 8, the effect of clamping, wrapping and removing the diseased tissue can be achieved according to the diseased tissue of different sizes.

[0035] The extension column 4 is provided with an opening and closing adjustment member for controlling the movement of the elastic picking cage bar 8, and the opening and closing adjustment member includes an arc-shaped through-hole 19 opened on the extension column 4, and a ball seat 16 connected to a sliding ring 18 is fixedly connected to an adjustment column 20, and the adjustment column 20 extends upward through the arc-shaped through-hole 19, and is connected to an opening and closing adjustment rotating ring 21 through a connecting block. An arc-shaped slide groove 17 is opened on the limit ring 5, and a sliding ring 18 adapted to the arc-shaped slide groove 17 is fixedly connected to the outer wall of a ball seat 16 located above.

[0036] It should be noted that in the present solution, when the diseased tissue needs to be removed through the removal end, if the diseased tissue is too large to pass through the distance between two adjacent elastic removal cage bars 8, the distance between the two elastic removal cage bars 8 can be adjusted by opening and closing the adjustment member, thereby enabling the larger diseased tissue to be loaded into the wrapping space formed by multiple elastic removal cage bars 8, thereby achieving the removal of the diseased tissue.

[0037] Furthermore, the control column 10, the control handle 9 and the extension column 4 are all provided with cylindrical openings that are compatible with the inner shaft column 12, the outer wall at the bottom of the inner shaft column 12 is provided with a limiting protrusion 22, the cutting seat 1 is provided with a docking opening 23, and the side wall of the docking opening 23 is provided with a combined recess 24 that is compatible with the limiting protrusion 22; the connecting end seat 14 is fixedly connected with a resistance column 25 that penetrates into the docking opening 23.

[0038] refer to Figure 7 The shape of the combined recess 24 is composed of a vertical groove, a transverse groove and a vertical groove. The arrangement can realize the docking fitting opening 23 at the transverse groove. During the upward pulling of the inner shaft column 12, a pulling force is generated on the cutting seat 1, so that the cutting seat 1 is pulled upward, so that the elastic picking cage bar 8 between the cutting seat 1 and the extension column 4 is squeezed outward and deformed into a "cage shape", ensuring that the magnetic force between the electromagnetic seat 6 and the permanent magnet seat 7 attracts each other.

[0039] The operating end includes a control handle 9 connected to the extension column 4, a control column 10 is fixedly connected to the top of the control handle 9, a control knob 11 is arranged on the top of the control column 10, the control knob 11 is connected to the cutting seat 1 through an inner shaft column 12, an adjustment seat 13 is arranged on the side wall of the control handle 9, and a resistance adjustment part for controlling the magnetic force of the electromagnetic seat 6 is arranged on the adjustment seat 13.

[0040] Furthermore, the resistance adjustment member includes a resistance column 26 arranged in the adjustment seat 13, a sliding push button 27 is arranged on the adjustment seat 13, and a wire connected to the electromagnetic seat 6 is arranged on the sliding push button 27. The setting of the resistance column 26 can change the conduction distance between the wire and the resistance column 26 when the sliding push button 27 is slid, thereby achieving the effect of adjusting the resistance to change the current, and realizing the control of the current size of the electromagnetic seat 6. This is a common technology and will not be elaborated here.

[0041] Furthermore, a threaded ring 28 is rotatably provided at the bottom of the control knob 11, and a threaded layer threadedly connected to the threaded ring 28 is provided on the outer wall of the control column 10. The setting of the threaded layer can ensure that after the control knob 11 moves the inner shaft column 12 to the bottom and the scalpel 3 is squeezed out, the threaded connection with the threaded layer can be achieved through the rotation of the threaded ring 28, thereby ensuring that the scalpel 3 is in a locked state during use.

[0042] During the use of the present invention in gynecological abdominal surgery, an operation hole is opened on the abdominal cavity to extend the cutting end into the abdominal cavity, and the surgical operation is carried out by the extended scalpel 3. When the diseased tissue needs to be removed, the connection between the threaded ring 28 and the threaded layer can be released by rotating the threaded ring 28, and the inner shaft column 12 can be driven to move by pulling back the control knob 11. The limiting protrusion 22 on the inner shaft column 12 is located at the docking matching port 23 at the transverse groove, which will drive the cutting seat 1 to move during the pulling back of the inner shaft column 12, so that the elastic cage strips 8 between the cutting seat 1 and the extension column 4 are squeezed outward and deformed into a "cage shape", and the permanent magnet seat 7 will gradually approach the distance between the electromagnetic seat 6, and the magnetic force of the two can be adsorbed after approaching. At this time, the inner shaft column 12 is rotated to release the cooperation between the limiting protrusion 22 and the combined recess 24. At this time, the magnetic force of the electromagnetic seat 6 can be controlled according to the required "cage shape" size, so that the space formed by the elastic cage strips 8 can meet the requirements of the diseased tissue.

[0043] Control the rotation of the opening and closing adjustment ring 21 to drive the connected adjustment column 20 to rotate, and the elastic extraction cage bar 8 connected to the adjustment column 20 will be driven to move, so that the distance between two adjacent elastic extraction cage bars 8 becomes larger, which is convenient for placing the diseased tissue therein, so that the diseased tissue is wrapped by multiple elastic extraction cage bars 8, and the diseased tissue is removed, which is convenient for the operation, and no extra operating holes are generated, thereby reducing harm to the patient.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
