Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a tissue extractor capable of carrying an endoscope. Background Art
[0002] A tissue extractor is a special medical device for collecting and containing surgically resected materials and facilitating their removal from the body. Generally speaking, a tissue extractor includes an inner sheath rod and an outer sheath rod. A collection bag is provided at the end of the inner sheath rod tube for containing the resected tissue organs. When the outer sheath rod enters the abdominal cavity, the collection bag can collect the resected tissue. After collection, the inner sheath handle is pulled outwards to tighten the bag mouth, and then the surgical specimen and the resected materials can be taken out.
[0003] When the collection bag collects the resected tissue, the doctor also needs to operate the endoscope to assist the doctor in smoothly collecting the diseased tissue into the collection bag by observing through the endoscope. At this time, the doctor needs to operate at least three instruments simultaneously, namely the endoscope, the tissue extractor, and the resection instrument. Operating multiple instruments simultaneously and coordinating with each other is rather troublesome for the doctor. Summary of the Invention
[0004] The purpose of the utility model is to solve the problems existing in the prior art, and provides a tissue extractor capable of carrying an endoscope, which can be paired with the endoscope, enabling the doctor to operate without additionally operating the endoscope when excising and collecting the diseased tissue in the patient's abdominal cavity, thereby reducing the operation difficulty of the doctor.
[0005] To achieve the above purpose, the utility model is realized by the following technical solutions: A tissue extractor capable of carrying an endoscope includes an outer rod, an inner rod is inserted through the outer rod. One end of the inner rod is provided with a bag mouth wire, and a collection bag is arranged on the bag mouth wire. An endoscope is arranged on the inner side of the outer rod near the bag mouth wire end, and a mounting plate for carrying the endoscope is arranged on the inner side of the outer rod near the bag mouth wire end. A mounting opening is formed on the outer side of the outer rod near the bag mouth wire end, and a wire groove communicated with the mounting opening is formed on the surface of the outer rod. A rotating cylinder for locking the endoscope is arranged on the surface of the outer rod, and a clamping block for clamping the endoscope is arranged on the inner wall of the rotating cylinder.
[0006] Through the above technical solutions, when collecting the diseased tissue in the patient's abdominal cavity, the endoscope and the tissue extractor are integrated. When collecting the diseased tissue, only by operating the tissue extractor can the endoscope synchronously observe the internal situation of the abdominal cavity, enabling the doctor not to need to additionally operate the endoscope, reducing the operation difficulty of the doctor, and making it simpler for the doctor to excise the diseased tissue. In addition, for the endoscope, both disassembly and assembly are very simple, facilitating the preoperative preparation work and the cleaning work of the endoscope after the operation.
[0007] Further, handles are arranged on both sides of the end of the outer rod away from the collection bag, and a pull ring is arranged at the end of the inner rod away from the bag mouth wire.
[0008] The handle and pull ring make it easy for the doctor to operate the retriever.
[0009] Furthermore, the outer side of the outer rod near one end of the collecting bag is provided with a rounded corner, and the inner side of the outer rod near one end of the collecting bag is provided with an outwardly expanding chamfer.
[0010] The rounded corners make it easier for the tip of the outer rod to be inserted into the patient's abdominal cavity, and the outward chamfered corners make it easier for the bag mouth wire to extend and retract from the outer rod.
[0011] Furthermore, an outer ring groove is provided on the outer surface of the outer rod, a limiting groove is provided on the surface of the outer ring groove, the limiting groove is an annular groove, the rotating cylinder is sleeved on the surface of the outer ring groove, and the clamping block is located in the limiting groove.
[0012] Twist the rotating cylinder to allow the rotating cylinder to drive the clamping block to slide in the limiting groove until it is engaged with the endoscope.
[0013] Furthermore, the rotating cylinder is a cylinder with a notch, the width of the notch of the rotating cylinder is not less than the width of the carrying port, the length of the rotating cylinder is less than the length of the carrying port, and the rotating cylinder overlaps with the carrying port.
[0014] The notch design of the rotating cylinder can be used as a mark to let the doctor know intuitively to what extent the rotating cylinder needs to be twisted to lock the endoscope. At the same time, the notch design also makes it convenient for the doctor to drag the endoscope out of the outer rod through the notch at a later time.
[0015] Furthermore, the outer diameter of the rotating cylinder is smaller than the outer diameter of the outer rod, and a plurality of damping strips arranged along the length direction of the rotating cylinder are evenly arranged on the surface of the rotating cylinder.
[0016] The above technical features can reduce the friction between the rotating cylinder and tissues when the outer rod is extended into the abdominal cavity, and the damping strip is provided to facilitate the rotation of the rotating cylinder.
[0017] Furthermore, a limiting plate is provided at one end of the carrying plate away from the collecting bag, and a threading hole is opened on the limiting plate.
[0018] The limit plate is used to support the endoscope, so that the doctor can know whether the endoscope is installed properly, and the threading port is used to pass the wire of the endoscope.
[0019] Furthermore, the upper surface of the inner mirror is a curved surface, the upper surface of the inner mirror is matched with the inner wall of the outer rod, the width of the inner mirror is greater than the width of the mounting port, and a wire is provided at the rear end of the inner mirror.
[0020] Through the above features, the stability of the endoscope in the outer rod is effectively guaranteed.
[0021] Furthermore, a limiting block adapted to the mounting port is provided on the surface of the endoscope, and a clamping groove adapted to the limiting groove is provided on the outer surface of the limiting block.
[0022] After the endoscope is installed into the outer rod, the card slot and the limit slot will be connected together to form a complete circular groove, so that it is convenient for the card block to slide from the limit slot into the card slot.
[0023] Furthermore, a chamfer is provided at the edge formed by the outer rod and a side of the carrying port close to the collecting bag, and a rounded flared opening is provided at the joint between the wire groove and the carrying port.
[0024] The chamfering and rounded flared designs are intended to reduce the scratching of tissues by the edges when the outer rod is inserted into the abdominal cavity.
[0025] Compared with the prior art, the beneficial effects of the utility model are: 1. When collecting the diseased tissue in the patient's abdominal cavity, it is only necessary to operate the retriever to allow the endoscope to simultaneously observe the situation inside the abdominal cavity, so that the doctor no longer needs to operate the endoscope additionally, reducing the doctor's operating difficulty and making it easier for the doctor to remove the diseased tissue; 2. For the endoscope, disassembly and assembly are very simple, which is convenient for preoperative preparations and postoperative cleaning of the endoscope; 3. The rotating cylinder with a notch design, the notch itself can be used as a mark, so that the doctor can intuitively know to what extent the rotating cylinder needs to be twisted to hold the main endoscope.

[0037] As Figure 1 —8 shows, the specific solution of the embodiment is as follows: An object extractor capable of carrying an endoscope 10 includes an outer rod 1, an inner rod 3 is inserted through the outer rod 1, a wire 4 at the bag opening is provided at one end of the inner rod 3, a collection bag 5 is provided on the wire 4 at the bag opening, an endoscope 10 is provided inside the outer rod 1 near one end of the wire 4 at the bag opening, a wire is provided at the tail end of the endoscope 10, a carrier plate 6 for carrying the endoscope 10 is provided inside the outer rod 1 near one end of the wire 4 at the bag opening, a loading port 8 is opened on the outer side of the outer rod 1 near one end of the wire 4 at the bag opening, a wire groove 9 communicating with the loading port 8 is opened on the surface of the outer rod 1, a rotating cylinder 7 for locking the endoscope 10 is provided on the surface of the outer rod 1, and a block 71 engaged with the endoscope 10 is provided on the inner wall of the rotating cylinder 7.
[0038] When collecting diseased tissues in the patient's abdominal cavity, the endoscope 10 is installed inside the outer rod 1 to integrate the endoscope 10 with the object extractor. When collecting diseased tissues, the doctor only needs to operate the object extractor to synchronously observe the internal situation of the abdominal cavity through the endoscope 10, so that the doctor no longer needs to operate the endoscope 10 additionally, reducing the operation difficulty of the doctor and making it easier for the doctor to remove diseased tissues. In addition, the disassembly and assembly are very simple, facilitating the preoperative preparation work and the cleaning work of the endoscope 10 after the operation.
[0039] As Figure 1As shown in the figure, handles 2 are provided on both sides of one end of the outer rod 1 away from the collection bag 5, and a pull ring is provided at one end of the inner rod 3 away from the wire 4 at the bag mouth. The handles 2 and the pull ring facilitate the doctor to operate the extractor.
[0040] As Figure 2 shown, a reduced opening rounded corner is provided on the outer side of the end of the outer rod 1 close to the collection bag 5. The reduced opening rounded corner is used to make the edge of the head end of the outer rod 1 rounder, so that it is easier to insert into the patient's abdominal cavity. At the same time, an outward expansion chamfer is provided on the inner side of the end of the outer rod 1 close to the collection bag 5 to reduce the friction between the wire 4 at the bag mouth and the inner wall edge of this end of the outer rod 1, and thus make it easier for the wire 4 at the bag mouth to extend and retract from the outer rod 1.
[0041] As Figures 3-4 shown, an outer ring groove 11 is provided on the outer surface of the outer rod 1. At the same time, a limiting groove 12 is provided on the surface of the outer ring groove 11. The limiting groove 12 is an annular groove. The rotating cylinder 7 is sleeved on the surface of the outer ring groove 11, and the clamping block 71 is located in the limiting groove 12. Twist the rotating cylinder 7 to drive the clamping block 71 to slide in the limiting groove 12 until it is clamped with the endoscope 10.
[0042] As Figure 2 、 Figure 8 shown, the rotating cylinder 7 is a cylinder with a notch. The width of the notch of the rotating cylinder 7 is not less than the width of the loading port 8, the length of the rotating cylinder 7 is less than the length of the loading port 8, and the rotating cylinder 7 overlaps with the loading port 8 in position.
[0043] The rotating cylinder 7 with a notch design can be used as a mark itself, enabling the doctor to intuitively know how much the rotating cylinder 7 needs to be twisted to clamp the endoscope 10. At the same time, the notch design also facilitates the doctor to later drag the endoscope 10 in the outer rod 1 from the notch.
[0044] It should be noted that the outer diameter of the rotating cylinder 7 is smaller than the outer diameter of the outer rod 1, which facilitates reducing the friction between the rotating cylinder 7 and the tissue when the outer rod 1 extends into the abdominal cavity. In addition, a plurality of damping strips arranged along the length direction of the rotating cylinder 7 are uniformly provided on the surface of the rotating cylinder 7 to facilitate the rotation of the rotating cylinder 7. At the same time, both ends of the damping strips are rounded, reducing the scraping between the edges at the ports of the damping strips and the tissue during the insertion of the outer rod 1.
[0045] As Figure 5 shown, a limiting plate 61 is provided at one end of the loading plate 6 away from the collection bag 5, and a wire passing hole is provided on the limiting plate 61. The limiting plate 61 is used to resist the endoscope 10 to facilitate the doctor to know whether the endoscope 10 is installed in place, and the wire passing hole is used to pass the wire of the endoscope 10 through.
[0046] As Figure 7As shown, the upper surface of the endoscope 10 is an arc surface, which is adapted to the inner side wall of the outer rod 1. The width of the endoscope 10 is greater than the width of the loading port 8, effectively ensuring the stability of the endoscope 10 inside the outer rod 1.
[0047] On the surface of the endoscope 10, there is a limiting block adapted to the loading port 8, and a clamping groove 101 adapted to the limiting groove 12 is provided on the outer surface of the limiting block; after the endoscope 10 is inserted into the outer rod 1, the clamping groove 101 and the limiting groove 12 will be connected together to form a complete circular groove, so as to facilitate the sliding of the clamping block 71 from the limiting groove 12 into the clamping groove 101.
[0048] As Figure 6 shown, a chamfer is provided at the corner formed by the loading port 8 close to the collection bag 5 and the outer rod 1, and a rounded flaring is provided at the docking part of the wire groove 9 and the loading port 8. The designs of the chamfer and the rounded flaring are both to reduce the scraping of the tissue by the corners during the process of the outer rod 1 extending into the abdominal cavity.
[0049] The working principle of the above embodiment is as follows: Before the operation, the endoscope 10 is inserted from the head end of the outer rod 1 until the tail end of the endoscope 10 abuts against the limiting plate 61. Then, the rotating cylinder 7 is rotated to make the clamping block 71 slide from the limiting groove 12 into the clamping groove 101, and the endoscope 10 can be fixed, thus combining with the outer rod 1 into one. Then, the wire of the endoscope 10 is placed into the wire groove 9 and extends out of the outer rod 1. Then, the outer rod 1 is extended into the abdominal cavity of the patient to collect the excised diseased tissue. When operating the outer rod 1, the endoscope 10 moves synchronously under the influence of the outer rod 1, and then continuously shoots the process of collecting the diseased tissue, without the need to operate the endoscope 10 additionally, so that the doctor's operation is simpler. When disassembling, rotate the rotating cylinder 7 again to make the clamping block 71 move out of the clamping groove 101, and then pull out the endoscope 10 from the loading port 8.
[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
