Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of thoracic surgery, and more particularly to a thoracic surgery object retriever. Background Art
[0002] Thoracic surgery is a type of surgery that focuses on organs within the chest cavity (such as the lungs, heart, esophagus, and other parts of the chest). It is commonly used to treat diseases such as lung cancer, chest injuries, or infections. Thoracic surgery can be performed using traditional open surgery or minimally invasive techniques such as video-assisted thoracic surgery (VATS). With the development of current medical technology, except for special circumstances, thoracic surgery is generally performed using minimally invasive techniques. In minimally invasive techniques, modern camera technology and high-tech surgical instruments are generally used to complete complex intrathoracic operations under chest wall cannulas or tiny incisions.
[0003] In current minimally invasive thoracic surgery, after the lesion inside the patient's chest cavity is removed, it needs to be removed from the wound using surgical instruments. On the one hand, the diseased tissue will directly contact the wound, forming blood contact, thereby increasing the risk of wound contamination. On the other hand, the wound is pulled outward by the diseased tissue, which will cause the probability of secondary damage to the wound, increase the difficulty of subsequent suturing and affect the patient's wound recovery effect. Summary of the Invention
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a thoracic surgical object retriever, which comprises a conical cover, a flat cavity, a deformation seam and an arc plate. The conical cover is first compressed and then pre-placed under the wound surface by a surgical instrument, and the flat cavity is kept exposed. After the diseased tissue is cut and brought into the interior of the conical cover, the conical cover can be shrunk along the deformation seam on its own surface to reduce its volume. The flat cavity on the outside is then controlled to be extracted upward, thereby simultaneously driving the entire conical cover upward and completely separating it from the patient's wound surface. At the same time, during the entire removal process, the removed diseased tissue will not directly contact the wound surface, thereby effectively avoiding contamination of the wound by the removed object and secondary damage to the wound, thereby improving the safety of the operation, and solving the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: A thoracic surgical object retriever comprises a conical cover, the conical cover tends to expand outward from top to bottom, a flat cavity is integrally formed at the top of the conical cover, the width of the flat cavity is greater than the width of the connection between the flat cavity and the deformation seam, a plurality of deformation seams are equidistantly divided circumferentially on the surface of the conical cover, an open mouth is provided at the top of the flat cavity, an arc-shaped surface is provided between the conical cover and the flat cavity, an arc-shaped plate is annularly distributed on the inner edge of the bottom end of the conical cover, a hook plate is fixedly installed at the end of the arc-shaped plate, a concave groove is provided at the connection between the arc-shaped plate and the hook plate, the arc-shaped plate as a whole extends toward the center position of the conical cover and gradually tilts upward, the end of the hook plate tilts and tilts toward the inner wall of the conical cover and forms an angle with the arc-shaped plate, the concave groove gradually extends toward the inside of the corner of the arc-shaped plate and the hook plate, and the concave groove is generally circular.
[0006] In a preferred embodiment, the conical cover is made of medical transparent material as a whole. The conical cover, flat cavity and deformation seam are arranged from top to bottom, with an outward expansion posture at the position of the flat cavity, a contraction posture at the position of the curved surface, and a gradually outward expansion posture at the position of the conical cover.
[0007] In a preferred embodiment, the cross-section of the deformation joint is semicircular, and the top end of the deformation joint extends to the lower edge of the arc surface, the bottom end of the deformation joint extends to the connection between the arc plate and the conical cover, and the concave direction of the deformation joint points to the inner center direction of the conical cover.
[0008] In a preferred embodiment, the entire surface of the conical cover is smooth, and the overall length of the conical cover is greater than the total length of the arc surface and the flat cavity.
[0009] In a preferred embodiment, the overall curvature of the flat cavity gradually increases from the middle to both sides, so that the overall cavity gradually presents an oblate shape.
[0010] In a preferred embodiment, the arc plate and the hook plate together form a hook-shaped structure, the end of the hook plate gradually forms a teardrop-shaped structure, and the volume of the end gradually expands outward, and the top surface of the hook plate is an arc-shaped surface structure.
[0011] In a preferred embodiment, the inner wall surface of the concave groove is set to be a frosted surface, and the connections between the two side tracks of the concave groove and the arc plate and the hook plate are rounded and smoothly transitioned.
[0012] The technical effects and advantages of the present invention are as follows:
[0013] The present invention provides a conical cover, a flat cavity, a deformation seam, and an arc plate, and utilizes the mutual cooperation of the conical cover. First, the conical cover is compressed and then pre-placed under the wound surface by a surgical instrument, while keeping the flat cavity exposed. After the diseased tissue is cut and brought into the interior of the conical cover, the conical cover can be contracted along the deformation seam on its own surface to reduce its volume. Then, the flat cavity on the outside is controlled to be extracted upward, thereby simultaneously driving the entire conical cover upward and completely out of the patient's wound surface, finally completing the removal of the diseased tissue. At the same time, during the entire removal process, the removed diseased tissue will not directly contact the wound surface, thereby effectively avoiding contamination of the wound by the removed object and secondary damage to the wound, thereby improving the safety of the operation.
[0014] During the removal process, when the instrument that fixes the diseased tissue loses force, causing the diseased tissue to tend to slip outside the conical cover, the hook plate on the inner side of the conical cover can effectively use its outward curved shape to block it, thereby reducing the operating difficulty for the operating physician, providing double protection for the fixation of the diseased tissue, and improving the safety of the overall structure.

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] As attached Figure 1 To the attached Figure 8 The thoracic surgical object retriever shown in the figure includes a conical cover 1, which tends to expand outward from top to bottom, and a flat cavity 2 is formed integrally at the top of the conical cover 1, the width of the flat cavity 2 is greater than the width of the connection between the flat cavity 2 and the deformation seam 3, and the surface of the conical cover 1 is circumferentially equidistantly divided with multiple deformation seams 3. Through the above arrangement, it can be ensured that the conical cover 1 can be retracted inwardly through the multiple deformation seams 3 provided on its own surface when being taken out, thereby effectively shrinking its volume, making it convenient for doctors to fix and remove it, and an open mouth 4 is provided at the top of the flat cavity 2, and an arc surface 5 is provided between the conical cover 1 and the flat cavity 2, and an inner edge part of the bottom end of the conical cover 1 is annularly distributed with an arc plate 6, and a hook plate 7 is fixedly installed at the end of the arc plate 6, and a concave groove 8 is provided at the connection part between the arc plate 6 and the hook plate 7, and the arc plate 6 as a whole extends toward the center position of the conical cover 1 and gradually tilts diagonally upward. The end of the hook plate 7 is tilted and tilted toward the inner wall of the conical cover 1, and forms an angled posture distribution with the curved plate 6, and the concave groove 8 gradually extends toward the inside of the corner of the curved plate 6 and the hook plate 7, and the concave groove 8 is in a circular posture as a whole. Through the above arrangement, the design of the curved plate 6 tilting upward and the cooperation of the hook plate 7, when the instrument fixes the diseased tissue, force loss occurs, resulting in the diseased tissue having a tendency to slip toward the outside of the conical cover 1, the diseased tissue will directly contact the surface of the curved plate 6 and be blocked by its inward-tilted curved surface. At the same time, the hook plate 7 on the side of the curved plate 6 can effectively use its own outward curved shape to hook it and directly block it, effectively preventing it from slipping. At the same time, the inward-tilted curved surface design of the curved plate 6 allows the diseased tissue to enter the conical cover 1 and slide smoothly from the surface of the curved plate 6. Once a tendency to loosen outward occurs, it is contacted and fixed by the curved surface of the curved plate 6.
[0026] The conical cover 1 and the flat cavity 2 are made of medical transparent materials as a whole. The conical cover 1, the flat cavity 2 and the deformation seam 3 are arranged from top to bottom. At the position of the flat cavity 2, they are in an outward expansion posture, at the position of the curved surface 5, they are in a contraction posture, and at the position of the conical cover 1, they are in a gradually outward expansion posture. The entire surface of the conical cover 1 is smooth, and the overall length of the conical cover 1 is greater than the total length of the curved surface 5 and the flat cavity 2. The overall curvature of the flat cavity 2 gradually increases from the middle to the two sides, so that the whole gradually presents an oblate shape. Through the above arrangement, it can be ensured that the conical cover 1 and the flat cavity 2 will not affect the operation The conical cover 1 is used as the surgeon's surgical sight, thereby ensuring the normal progress of the operation. At the same time, the overall morphological characteristics of the conical cover 1, the flat cavity 2 and the deformation seam 3 are utilized to ensure that the conical cover 1 can be pre-placed below the wound surface by surgical instruments, and the flat cavity 2 above the conical cover 1 is located above the wound surface. The curved surface 5 between the flat cavity 2 and the conical cover 1 is utilized to contact the wound surface. On the one hand, it can prevent the minimally invasive wound from closing prematurely, and on the other hand, it can ensure that the insertion depth of the conical cover 1 is guaranteed, and after reaching the predetermined depth, it will not go too deep due to the obstruction of the flat cavity 2, thereby improving the safety of the conical cover 1.
[0027] For details, please refer to the attached manual Figure 3 -Attached Figure 7 The cross-section of the deformation seam 3 is semicircular, and the top end of the deformation seam 3 extends to the lower edge of the arc surface 5, and the bottom end of the deformation seam 3 extends to the connection between the arc plate 6 and the conical cover 1. The concave direction of the deformation seam 3 points to the inner center direction of the conical cover 1.
[0028] The specific implementation method is: using the above-mentioned setting, it can be ensured that when the conical cover 1 as a whole shrinks inward, it can shrink inward according to the shrinkage direction of the deformation seam 3 and the overall length range, ensuring that the shape of the conical cover 1 after shrinkage is much smaller than the posture when relaxed, thereby ensuring that the conical cover 1 can be smoothly removed from the patient's wound surface, thereby improving the practicality of the structure.
[0029] For details, please refer to the attached manual Figure 6 The arc plate 6 and the hook plate 7 together form a hook-shaped structure. The end of the hook plate 7 gradually forms a teardrop-shaped structure, and the volume of the end gradually expands outward. The top surface of the hook plate 7 is an arc-shaped surface structure, and the inner wall surface of the concave groove 8 is set to a frosted surface. The connection between the two side tracks of the concave groove 8 and the arc plate 6 and the hook plate 7 is a rounded and smooth transition.
[0030] The specific implementation method is as follows: using the above-mentioned arrangement, it can be ensured that after the diseased tissue cut by the operation slides into the interior of the conical cover 1 through the surgical instrument, the diseased tissue can be restricted by the hook plate 7 at the lower end. When the diseased tissue tends to slide out of the conical cover 1, the hook plate 7 can effectively block it, thereby reducing the operating difficulty of the operating physician and improving the safety of the overall structure. The end of the hook plate 7 is used to gradually form a water drop-shaped structure. When the surgical instrument hooks the concave groove 8 on the side of the hook plate 7 inside the conical cover 1 and pulls the conical cover 1, once the surgical instrument slides between the concave groove 8, the end of the hook plate 7 above the concave groove 8 will use its own water drop-shaped curvature to block the sliding surgical instrument, thereby improving the fixing effect between it and the concave groove. At the same time, the surgical instrument here can adopt a series of existing instruments such as existing surgical forceps and surgical clamps.
[0031] Working principle of the present invention:
[0032] Step 1: First, the operating physician performs the thoracic surgery process normally, and compresses the conical cover 1 and places it under the wound surface in advance through surgical instruments, and ensures that the flat cavity 2 above the conical cover 1 is located above the wound surface, keeping the flat cavity 2 exposed, so as to utilize the curved surface 5 between the flat cavity 2 and the conical cover 1 to contact the wound surface. On the one hand, it can prevent the minimally invasive wound from closing prematurely, and on the other hand, it can ensure that the insertion depth of the conical cover 1 is guaranteed, and after reaching the predetermined depth, it will not continue to go deeper due to the obstruction of the flat cavity 2, thereby improving its insertion safety.
[0033] Step 2: First, the operating physician performs the operation normally. After removing the patient's diseased tissue, the surgical instrument can be driven to slide into the interior of the conical cover 1. At this time, the concave groove 8 on the side of the hook plate 7 inside the conical cover 1 is hooked with additional instruments and pulled toward the center of the conical cover 1, thereby driving the entire conical cover 1 to gradually shrink inward. According to the shrinkage direction of the deformation joint 3 and its overall length range, the overall posture of the conical cover 1 is controlled to shrink inward, thereby ensuring that the shape of the conical cover 1 after shrinkage is much smaller than the posture when it is relaxed. At this time, the external flat cavity 2 is extracted upward, thereby synchronously driving the entire conical cover 1 to shrink inward. The conical cover 1 is lifted upward and completely separated from the patient's wound, finally completing the removal of the diseased tissue. During the removal process, when the instrument fixing the diseased tissue loses force, causing the diseased tissue to tend to slide to the outside of the conical cover 1, the hook plate 7 on the inner side of the lower side of the conical cover 1 can effectively use its own outward curved shape to block it, thereby reducing the operating difficulty of the operating physician, providing double protection for the fixation of the diseased tissue, and improving the safety of the overall structure. At the same time, during the entire removal process, the excised diseased tissue will not directly contact the wound, thereby effectively avoiding contamination of the wound by the excised object and secondary damage to the wound, thereby improving the safety of the operation.
[0034] Step 3: First, the operator shuts down the device normally, then checks whether the fixation between the various components of the device is normal, and then replaces and repairs the aging and severely worn parts inside the device.
