Description

Technical Field

[0001] This invention relates to the field of surgical instruments, and more particularly to a retrieval device for gynecological abdominal surgery. Background Technology

[0002] Laparoscopic surgery is a minimally invasive procedure. Generally, during laparoscopic surgery, a certain amount of gas is first inflated into the abdominal cavity to create space, allowing the laparoscope to be inserted for observation. Several operating ports are made on the abdominal surface during the procedure, and corresponding instruments are inserted through these ports to perform the surgical operations. The number of operating ports depends on the required number of instruments. Too many operating ports can cause unnecessary harm to the patient. Furthermore, current retrieval instruments require large operating ports to accommodate different sizes of tissue, which can hinder patient recovery and interfere with the surgical procedure. Therefore, a retrieval instrument for gynecological laparoscopic surgery is proposed. Summary of the Invention

[0003] The purpose of this invention is to solve the problem that in the prior art, when there are too many surgical instruments, too many operating holes will cause unnecessary harm to the patient, and that the current retrieval instruments require operating holes to be made to accommodate the insertion of the retrieval instrument when taking tissue of different sizes during surgery. The operating holes are too large and are not conducive to the patient's recovery. Therefore, this invention proposes a retrieval instrument for gynecological abdominal surgery.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A retrieval device for gynecological abdominal surgery, the main body of the retrieval device is composed of a control end, a retrieval end and a cutting end, the cutting end includes a cutting seat, the end of the cutting seat is provided with a storage groove, and the inner wall of the storage groove is connected to a surgical knife through a telescopic storage component;

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] In the description of this invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" 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 an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Example, refer to Figures 1 to 8 A retrieval device for gynecological abdominal surgery. The main body of the retrieval device consists of a control end, a retrieval end, and a cutting end. The cutting end includes a cutting seat 1, and a storage groove 2 is provided at the end of the cutting seat 1. A surgical knife 3 is connected to the inner wall of the storage groove 2 through a telescopic storage component. Further, the telescopic storage component includes a connecting end seat 14 that is slidably disposed in the storage groove 2. The surgical knife 3 is fixedly disposed on the connecting end seat 14. The connecting end seat 14 is connected to the inner wall of the storage groove 2 through a return spring.

[0032] During gynecological abdominal surgery, the scalpel 3 participates in the surgical process. When the surgical cutting is completed, the scalpel 3 can be stored away, and the diseased tissue after the surgical cutting can be removed through the retrieval end. Compared with traditional surgery, this can reduce the number of operating holes in the abdominal cavity and reduce harm to the human body.

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

[0034] It should be noted that the electromagnetic base 6 and the permanent magnet base 7 are attracted by magnetic force. The magnetic force of the electromagnetic base 6 follows the magnitude of the current, and the magnitude of the magnetic force can be flexibly adjusted. This allows control over the magnetic attraction between the electromagnetic base 6 and the permanent magnet base 7, thereby allowing adjustment of the bending degree of the elastic retrieval cage bar 8 set between the two. By changing the bending degree of the elastic retrieval cage bar 8, the effect of clamping, wrapping, and removing diseased tissue of different sizes can be achieved.

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

[0036] It should be noted that in this solution, when the lesion tissue is too large to pass through the gap between two adjacent elastic retrieval cage bars 8 during the process of removing the lesion tissue through the retrieval end, the gap between the two elastic retrieval cage bars 8 can be adjusted by the opening and closing adjustment component, so as to put the larger lesion tissue into the encapsulation space composed of multiple elastic retrieval cage bars 8 and realize the removal of the lesion tissue.

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

[0038] refer to Figure 7 The combined notch 24 is composed of a vertical groove, a horizontal groove, and a vertical groove. This arrangement enables the mating joint 23 to be located at the horizontal groove. During the upward traction of the inner shaft column 12, a pulling force is generated on the cutting seat 1, causing the cutting seat 1 to be pulled upward. This causes the elastic picking cage bar 8 between the cutting seat 1 and the extension column 4 to be squeezed outward and deformed into a "cage shape", ensuring that the electromagnetic seat 6 and the permanent magnet seat 7 attract each other magnetically.

[0039] The control 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 provided on the top of the control column 10. The control knob 11 is connected to the cutting seat 1 through the inner shaft column 12. An adjustment seat 13 is provided on the side wall of the control handle 9. A resistance adjustment component for controlling the magnetic force of the electromagnetic seat 6 is provided on the adjustment seat 13.

[0040] Furthermore, the resistance adjustment component includes a resistance column 26 disposed within the adjustment base 13. The adjustment base 13 is provided with a sliding push button 27, and a wire connected to the electromagnetic base 6 is disposed 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 slidable, thereby achieving the effect of adjusting the resistance to change the current and realizing the control of the current magnitude of the electromagnetic base 6. This is a common technology and will not be described in detail here.

[0041] Furthermore, the bottom of the control knob 11 is provided with a threaded ring 28, and the outer wall of the control column 10 is provided with a threaded layer that is threadedly connected to the threaded ring 28. The threaded layer ensures that when the control knob 11 moves the inner shaft column 12 to the bottom and the scalpel 3 is extruded, the threaded ring 28 can be rotated to achieve a threaded connection with the threaded layer, ensuring that the scalpel 3 is in a locked state during use.

[0042] In gynecological abdominal surgery, this invention involves opening an operating hole in the abdominal cavity to insert the cutting end into the cavity. The extended scalpel 3 is used to participate in the surgery. When it is necessary to remove diseased tissue, the connection between the threaded ring 28 and the threaded layer can be released by rotating the threaded ring 28. The inner shaft column 12 is moved by pulling back the control knob 11. The limiting protrusion 22 on the inner shaft column 12 is located at the mating joint 23 at the transverse groove. During the pull-back of the inner shaft column 12, the cutting seat 1 is moved, thereby squeezing the elastic retrieval cage 8 between the cutting seat 1 and the extension column 4 outward to form a "cage". The distance between the permanent magnet seat 7 and the electromagnetic seat 6 gradually decreases. After they get close, the magnetic force of the two attracts them. At this time, rotating the inner shaft column 12 releases the engagement 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 size of the "cage" so that the space formed by the elastic retrieval cage 8 can meet the requirements for holding the diseased tissue.

[0043] Controlling the rotation of the opening and closing adjustment ring 21 causes the connected adjustment column 20 to rotate, which in turn moves the elastic retrieval cage 8 connected to the adjustment column 20. This increases the distance between two adjacent elastic retrieval cages 8, making it easier to place the lesion tissue inside. By using multiple elastic retrieval cages 8, the lesion tissue can be wrapped and removed, facilitating the surgery and avoiding unnecessary operating holes, thus reducing harm to the patient.

[0044] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
