Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to an endoscopic surgery retrieval bag. Background Art

[0002] Endoscopic surgical retrieval bags, as an indispensable tool in modern medicine, are mainly used in laparoscopic surgery to safely remove biopsy samples from the surgical area. Endoscopic surgical retrieval bags generally include an inner sheath rod and an outer sheath rod. A collecting bag is provided at the end of the inner sheath rod tube to hold the removed tissues and organs. When the outer sheath rod enters the abdominal cavity, the collecting bag can collect the removed tissues. After the collection is completed, the inner sheath handle is pulled outward to tighten the bag mouth to remove the surgical specimens and removed objects.

[0003] With the existing endoscopic surgical retrieval bag, when performing endoscopic surgery, the cutter, endoscope, and endoscopic surgical retrieval bag need to be inserted into the patient's cavity, and the three devices must be operated simultaneously, which places high technical requirements on the doctor's operation. In addition, due to the limited space in the patient's cavity, it is more troublesome to move the three devices in the patient's cavity. Moreover, after collecting the removed tissue, not only does the endoscopic surgical retrieval bag need to be discarded as a whole, but the endoscope also needs to be cleaned and disinfected. Summary of the invention

[0004] The purpose of the utility model is to address the problems existing in the prior art and to provide an endoscopic surgical retrieval bag. By integrating the traditional disposable endoscopic surgical retrieval bag with the endoscope, the doctor can reduce the use of equipment during endoscopic surgery and the operation is more convenient. In addition, by embedding the endoscope into the endoscopic surgical retrieval bag, only some parts need to be discarded after use, thereby reducing costs.

[0005] To achieve the above-mentioned purpose, the following technical scheme is adopted: an endoscopic surgical retrieval bag, comprising an outer rod, a disposable inner rod is inserted into the outer rod and runs through the length direction of the outer rod, the disposable inner rod comprises a pull-out rod located inside the disposable inner rod and two bag-mouth rods arranged at one end of the pull-out rod, the other ends of the two bag-mouth rods are jointly provided with a front end ball, the other end of the pull-out rod is provided with a tail end ball, a disposable collecting bag is jointly provided on the surface of the two bag-mouth rods, a tail ring is provided at one end of the pull-out rod close to the tail end ball, a groove matched with the pull-out rod and the tail end ball is provided on the surface of the tail ring, an endoscope is provided on the inner wall of the outer rod close to the front end ball, and a fixing ring is provided on the surface of the outer rod close to the tail ring.

[0006] Through the above technical solution, the traditional endoscopic surgical retrieval bag is divided into two parts, the outer rod and the tail ring are reused, and the endoscope is implanted in the outer rod, and the disposable inner rod and the disposable collection bag are used once. With this design, when the doctor performs endoscopic surgery, the amount of equipment used can be reduced, and the limited space in the patient's cavity provides relatively more space for operation. Moreover, compared with the disposable endoscopic surgical retrieval bags on the market, after use, only the disposable inner rod and the disposable collection bag need to be discarded, while the outer rod and the tail ring can be reused. Compared with the traditional endoscopic surgical retrieval bag that is discarded as a whole after use, the present application reduces the number of discarded parts and effectively reduces costs. During installation, only the disposable inner rod needs to be passed through the head end of the outer rod, and then the tail end of the disposable inner rod needs to be inserted into the slot in the tail ring to complete the assembly. The operation method is extremely convenient.

[0007] Optionally, the outer surface of the outer rod near one end of the front end ball is provided with a reduced diameter fillet and the inner wall of the same end is provided with an inner expanded fillet.

[0008] The design of reduced diameter and rounded corners can reduce the scratching feeling caused by the edges and corners of the outer wall when the outer rod tip is inserted into the patient's cavity, making it easier to insert the outer rod into the patient's cavity;

[0009] The design of the inner rounded corners reduces the resistance of the inner wall edges to the bag mouth rod when the bag mouth rod is retracted into the outer rod, making it easier for the bag mouth rod to retract and seal.

[0010] Optionally, the endoscope includes a mounting seat arranged on the inner wall of the outer rod, a lens arranged inside the mounting seat, and a fill light arranged inside the mounting seat and located on both sides of the lens, and the lens is facing the disposable collection bag.

[0011] By setting an endoscope at the tip of the outer rod, medical staff can observe more clearly and accurately when collecting tissues from patients;

[0012] The two fill lights can provide a good lighting environment for camera shooting, allowing doctors to observe the situation more clearly during surgery.

[0013] Optionally, the tail ring includes a ring body and a docking sleeve arranged outside the ring body, and the docking sleeve is threadedly connected to the outer rod.

[0014] When in use, separate the tail ring from the outer rod. After use, connect the tail ring to the outer rod to avoid losing the tail ring.

[0015] Optionally, the clamping groove is composed of a straight groove opened from the outer wall of the docking tube to the center of the docking tube and a limiting groove opened on the inner wall of the ring body, and the straight groove is connected to the limiting groove.

[0016] Optionally, the straight groove is adapted to the pull rod, and the limiting groove is adapted to the tail end ball.

[0017] The pull rod is inserted from the straight groove into the center of the docking tube until the tail end ball moves to the limit groove, and then the pull rod or the docking tube is pulled to embed the tail end ball into the limit groove to complete the one-time connection between the inner rod and the tail ring. When disassembling, push the tail ring toward the outer rod to move the tail end ball out of the limit groove, and then the pull rod can be taken out of the straight groove.

[0018] Compared with the prior art, the utility model has the following beneficial effects: 1. The traditional endoscopic surgical retrieval bag is divided into two parts, the outer rod and the tail ring are reused, and the endoscope is implanted in the outer rod, and the disposable inner rod and the disposable collection bag are disposable. With this design, when the doctor performs endoscopic surgery, the amount of equipment used can be reduced, and the operation space in the limited space of the patient's cavity is relatively larger; 2. Compared with the commercially available disposable endoscopic surgical retrieval bags, after use, only the disposable inner rod and the disposable collection bag need to be discarded, while the outer rod and the tail ring can be reused. Compared with the traditional endoscopic surgical retrieval bags, As for the way of discarding the whole endoscopic surgical retrieval bag after use, the present application reduces the number of discarded parts and effectively reduces the cost; 3. During installation, only the disposable inner rod needs to be passed through the head end of the outer rod, and then the pull-out rod is inserted from the straight groove into the center of the docking tube until the tail end ball moves to the limit groove, and then the pull-out rod or the docking tube is pulled to embed the tail end ball into the limit groove to complete the connection between the disposable inner rod and the tail ring. The connection is stable. When disassembling, push the tail ring toward the outer rod to move the tail end ball out of the limit groove, and then the pull-out rod can be taken out of the straight groove and the tail end of the disposable inner rod can be inserted into the slot in the tail ring to complete the assembly.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] like Figure 1 —5, the specific scheme of the embodiment is as follows: an endoscopic surgical retrieval bag, comprising an outer rod 1, a disposable inner rod 2 is inserted into the outer rod 1 and passes through the length direction of the outer rod 1, the disposable inner rod 2 comprises a pull-out rod 21 located in the disposable inner rod 2 and two bag-mouth rods 22 arranged at one end of the pull-out rod 21, a front end ball 3 is commonly provided at the other end of the two bag-mouth rods 22, a tail end ball 4 is provided at the other end of the pull-out rod 21, a disposable collecting bag 5 is commonly provided on the surface of the two bag-mouth rods 22, a tail ring 6 is provided at one end of the pull-out rod 21 near the tail end ball 4, a groove 7 adapted to the pull-out rod 21 and the tail end ball 4 is provided on the surface of the tail ring 6, an endoscope 8 is provided on the inner wall of the end of the outer rod 1 near the front end ball 3, and a fixing ring 9 is provided on the surface of the outer rod 1 near the tail ring 6.

[0028] like Figure 1 As shown, in this embodiment, the left end of the outer rod 1 is set as the head end, and the right end of the outer rod 1 is set as the tail end.

[0029] In this embodiment, the traditional endoscopic surgical sample collection bag is divided into two parts, the outer rod 1 and the tail ring 6 are reused, and the disposable inner rod 2 and the disposable collection bag 5 are disposable. When the doctor performs endoscopic surgery, the amount of instruments used can be reduced, and the limited space in the patient's cavity can provide a relatively larger operating space.

[0030] In addition, compared with the disposable endoscopic surgical retrieval bags on the market, after use, only the disposable inner rod and the disposable collection bag need to be discarded, while the outer rod and the tail ring can be reused. Compared with the traditional endoscopic surgical retrieval bag, which is discarded as a whole after use, the present application reduces the number of discarded parts and effectively reduces costs.

[0031] During installation, it is only necessary to pass the disposable inner rod 2 through the head end of the outer rod 1, and then insert the tail end of the disposable inner rod 2 into the slot 7 in the tail ring 6 to complete the assembly, and the operation method is extremely convenient.

[0032] It should be noted here that the outer rod 1 and the tail ring 6 are made of medical grade stainless steel, the disposable inner rod 2 is made of memory steel wire throughout, and the disposable collecting bag 5 is made of hydrophilic film. Since the memory steel wire is recyclable, when processing medical waste, only the disposable collecting bag 5 needs to be processed, which further reduces the cost.

[0033] It should be noted here that before and after each use, the outer rod 1, the tail ring 6 and the endoscope 8 disposed in the outer rod 1 must be cleaned and sterilized by high temperature and ultraviolet rays.

[0034] like Figure 2 or Figure 5 As shown, in this embodiment, the outer surface of the outer rod 1 near the front end ball 3 is provided with a reduced diameter fillet and the inner wall of the same end is provided with an inner expanded fillet.

[0035] The design of reduced diameter and rounded corners can reduce the scratching feeling caused by the edges and corners of the outer wall when the tip of the outer rod 1 is inserted into the patient's cavity, making it easier for the outer rod 1 to be inserted into the patient's cavity;

[0036] The design of the inner rounded corners reduces the resistance of the inner wall edges to the bag mouth rod 22 when the bag mouth rod 22 is retracted into the outer rod 1, making it easier for the bag mouth rod 22 to retract and seal.

[0037] In this embodiment, the diameter of the front end ball 3 is larger than the inner diameter of the outer rod 1. When the disposable collecting bag 5 is closed, the front end ball 3 abuts against the inner fillet of the outer rod 1, thereby making the head end of the outer rod 1 more rounded, allowing the outer rod 1 to shuttle more smoothly in the patient's cavity.

[0038] like Figure 5 As shown, the endoscope 8 includes a mounting base 81 arranged on the inner wall of the outer rod 1, a lens 82 arranged inside the mounting base 81, and a fill light 83 arranged inside the mounting base 81 and located on both sides of the lens 82, and the lens 82 faces the disposable collection bag 5.

[0039] By arranging an endoscope 8 at the head end of the outer rod 1, medical staff can observe more clearly and accurately when collecting patient tissues; in addition, two fill lights 83 can provide a good lighting environment for the lens 82 to shoot, allowing the doctor to observe the situation more clearly during the operation.

[0040] like Figure 3~4 As shown, the tail ring 6 includes a ring body 61 and a docking sleeve 62 arranged outside the ring body 61, and the docking sleeve 62 is threadedly connected to the outer rod 1.

[0041] When in use, the tail ring 6 is separated from the outer rod 1. After use, the tail ring 6 is docked with the outer rod 1 to avoid loss of the tail ring 6.

[0042] like Figure 3-4 As shown, in this embodiment, the slot 7 is composed of a straight slot 71 opened from the outer wall of the docking tube 62 to the center of the docking tube 62 and a limiting slot 72 opened on the inner wall of the ring body 61, and the straight slot 71 is connected to the limiting slot 72; the straight slot 71 is adapted to the pull rod, and the limiting slot 72 is adapted to the tail end ball 4.

[0043] When in use, the pull rod 21 is inserted from the straight groove 71 into the center of the docking tube 62 until the tail end ball 4 moves to the limit groove 72, and then the pull rod 21 or the docking tube 62 is pulled to allow the tail end ball 4 to be embedded in the limit groove 72, thereby completing the connection between the disposable inner rod 2 and the tail ring 6. When disassembling, the tail ring 6 is pushed toward the outer rod 1 to allow the tail end ball 4 to move out of the limit groove 72, and the pull rod 21 can be taken out from the straight groove 71.

[0044] Working principle: Before use, assemble first. First, pass the disposable inner rod 2 through the head end of the outer rod 1, and then insert the pull rod 21 from the straight groove 71 into the center of the docking tube 62 until the tail ball 4 moves to the limit groove 72, and then pull the pull rod 21 or the docking tube 62 to allow the tail ball 4 to be embedded in the limit groove 72, so that the connection between the disposable inner rod 2 and the tail ring 6 is completed, and the connection is stable;

[0045] After use, the disposable inner rod 2 and the outer rod 1 are disassembled. First, the tail ring 6 is pushed toward the outer rod 1 to move the tail end ball 4 out of the limit groove 72, and the pull rod 21 can be taken out from the straight groove 71. Then the disposable inner rod 2 and the disposable collecting bag 5 are discarded, and then the outer rod 1, the tail ring 6 and the endoscope 8 are cleaned and sterilized.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
