Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a foreign body remover used in conjunction with a cooperative bronchoscope. Background Art

[0002] Collaborative bronchoscopic foreign body removal is a medical technology mainly used to treat tracheobronchial foreign bodies, which is a common emergency, especially among children and the elderly. The clamping part is an important structure in the collaborative bronchoscope, also called a foreign body remover. After locating the foreign body through the bronchoscope, it can enter the bronchus and clamp the outside of the foreign body. After clamping the foreign body, it can be taken out by retrieving the foreign body remover.

[0003] The existing foreign body extractor enters the patient's body through the inside of the guide tube, reaches the foreign body and clamps it. The foreign body extractor includes an operating rod, a clamping claw, an elastic extrusion piece and a steel cable. The extension and contraction of the clamping claw is controlled by pulling the steel cable by a control unit to clamp and remove the foreign body. Most of the existing foreign body extractors are disposable products and need to be discarded as a whole after each use. However, in fact, the part operated by medical staff will not come into contact with the patient, and there is a possibility of repeated use. The overall disposable use will result in a large amount of resource waste. The connection between the steel cable and the operating part in the prior art is mostly a fixed connection. Once the connection method is changed, it is easy to affect the stability of the operation when the operating part pulls the steel cable, and it is difficult to take into account the portability of the separation between the operating part and the steel cable. Therefore, the present application provides a foreign body extractor for use with a collaborative bronchoscope to meet the needs. Summary of the invention

[0008] Optionally, the connecting assembly includes a slot on the connecting head and a connecting piece symmetrically installed at the end of the second connecting rod, the end of the connecting piece is fixedly connected to a connecting seat that is adapted to the external shape of the connecting head, and the inner side of the connecting seat is fixedly connected to a card block that is adapted to the shape of the slot.

[0009] Optionally, a second active cavity adapted to the size of the second connecting rod is provided between the fitting seat and the first operating handle, the second active cavity is connected to the first active cavity, a through opening connected to the second active cavity is provided on the outside of the fitting seat, and a paddle is fixedly connected to the outside of the connecting seat and extends through the through opening to the outside of the fitting seat.

[0010] Optionally, a second weakened portion is opened in the middle of the connecting piece, the second weakened portion is semicircular, and support frames are symmetrically connected to both ends of the second weakened portion, and the support frames are located at the opening of the second weakened portion.

[0011] Optionally, the adjustment assembly includes a rubber ring fixedly connected to the fixed head and a sleeve groove opened on the inner side wall of the sleeve seat, the sleeve groove is adapted to the shape of the rubber ring, the ends of the sleeve seat and the fixed head are both provided with inclined surfaces, and the steel cable and the connecting head are movably connected via a rotating shaft.

[0012] Optionally, a connecting cavity matching the thickness value of the end of the fitting seat is provided in the fixing head, and there are two groups of rubber rings, both of which are located in the connecting cavity. The outside of the rubber ring is fixedly connected with evenly distributed rubber sheets, and the rubber sheet is provided with a limiting groove matching the shape of the rubber sheet.

[0013] Optionally, the positioning assembly includes an elastic plate fixedly connected to the outside of the second operating handle, the end of the elastic plate is fixedly connected with a positioning head facing the outside of the first operating handle, and the outside of the first operating handle is provided with a positioning groove adapted to the shape of the positioning head.

[0014] Optionally, the elastic plate is wavy in shape, and a first weakened portion is provided in the middle of the elastic plate, and a width and a thickness of the first weakened portion are both smaller than a width and a thickness of the elastic plate.

[0015] Optionally, there are three groups of positioning grooves, and the distance between the topmost positioning groove and the bottommost positioning groove is the same as the length of the through opening.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, by setting up a connecting component, the introduction tube and the first operating handle are no longer in a fixed connection relationship, but can be kept in a connected and fixed state in the working state through the connecting component, and after the foreign body removal work is completed, the connecting component is disconnected, so that the introduction tube and the steel cable can be disassembled and replaced separately, while the structures on the first operating handle and the second operating handle are retained and reused, which greatly reduces the waste of medical resources while meeting the medical and health standards.

[0018] By providing a paddle and a second weakened portion and a support frame in the connecting assembly, when the connecting assembly is in a connected state, when the second operating handle is pushed, the symmetrical support frames on the connecting piece can press against each other to support the structure of the connecting piece, thereby avoiding deformation of the second weakened portion, ensuring the displacement effect of the steel cable when the second operating handle is pushed, and ensuring that the clamping forceps can work normally. When the connection state of the connecting assembly needs to be disconnected, the paddle can be pulled to drive the connecting piece to bend and deform at the second weakened portion, thereby driving the connecting seat to move, so that the card block withdraws from the card slot, and the connection state of the connecting assembly is released, so that the structure of the connecting assembly is stable and reliable in the connected state, and the disconnection operation is simple and convenient, and easy for medical staff to use.

[0019] By setting up the adjustment component, after the steel cable and the second connecting rod are connected and fixed by the connecting component, when the second operating handle is pushed and pulled to drive the steel cable to drive the clamping forceps to open and close and clamp foreign objects in the bronchus, the medical staff can rotate the fixed head in the adjustment component to make the introduction tube and the steel cable as a whole deflect along with the fixed head, and then adjust the angle of the clamping forceps in the bronchus to meet the needs of clamping foreign objects in different positions.

[0020] By setting the rubber ring, rubber sheet, sleeve groove and limit groove in the adjustment component, when adjusting the angle of the clamping forceps in the bronchus through the adjustment component, the rubber ring follows the rotation of the fixed head and moves relative to the sleeve groove. After each deflection by a certain angle, the rubber sheet will be embedded in the limit groove at the corresponding position, thereby realizing auxiliary positioning of the fixed head, so that after loosening the fixed head, the adjusted angle of the clamping forceps can be maintained, ensuring the stability of the clamping forceps during operation after the angle is adjusted.

[0021] By setting up the positioning component, the medical staff needs to move the positioning component when operating the second operating handle to drive the steel cable to push and pull, so that the positioning head withdraws from the positioning slot and releases the lock on the second operating handle. When the second operating handle moves to other fixed points following the push and pull operation of the medical staff, loosening the elastic plate can form a snap-fitting relationship between the positioning head and the positioning slot at the corresponding position, and then the second operating handle is locked again, so that the opening and closing of the clamping forceps can be locked by the positioning component after the push and pull operation of the second operating handle is realized, so that the clamping forceps can clamp the foreign body in the bronchus, and the clamping forceps in the closed state can be locked during the clamping process to ensure the stability of the foreign body during the removal process.

[0041] like Figures 1 to 10 As shown, an embodiment of the present invention provides a foreign body remover for use with a cooperative bronchoscope, comprising a first operating handle 1, a second operating handle 2 and a cooperative bronchoscope 3, the second operating handle 2 is externally fixedly connected to a first connecting rod 17 and a second connecting rod 18 extending into the first operating handle 1, the first operating handle 1 is externally fixedly connected to a set seat 6, the set seat 6 is externally sleeved with a fixed head 8, the fixed head 8 is fixedly connected to an introduction tube 5, a steel cable 9 is provided in the set seat 6, one end of the steel cable 9 is provided with a clamping forceps 11, and the other end of the steel cable 9 is provided with a connecting head 10, the cooperative bronchoscope 3 is externally fixedly connected to the introduction tube 5, and the foreign body remover 10 ... The introduction port 4 is adapted to the size of the tube 5. The introduction port 4 set on the cooperative bronchoscope 3 allows the introduction tube 5 to enter from the introduction port 4 and follow the bronchoscope into the patient's bronchus. The second operating handle 2 and the first operating handle 1 can move, so that when the second operating handle 2 is pushed and pulled, the steel cable 9 in the introduction tube 5 can be moved, and then the steel cable 9 is used to pull the clamping forceps 11 to open and close, so that the clamping forceps 11 can open after entering the patient's bronchus and clamp the foreign body to clamp the foreign body. The principles and usage of the introduction tube 5, steel cable 9 and clamping forceps 11 are the same as those in the prior art and will not be elaborated here.

[0042] A connecting component is used for the associative connection between the steel cable 9 and the second connecting rod 18. The connecting component is connected to the connecting head 10 and the second connecting rod 18 respectively. The setting of the connecting component makes the introduction tube 5 and the steel cable 9 no longer have a fixed connection with the set seat 6 and the second operating handle 2. The introduction tube 5 and the set seat 6 can be disassembled. The steel cable 9 and the second operating handle 2 are also a detachable structure, so that the introduction tube 5 and the set seat 6 can be disassembled and replaced after use, while other structures such as the first operating handle 1, the second operating handle 2 and the set seat 6 can be retained and reused, thereby achieving the purpose of reducing the waste of medical resources; an adjusting component is used for the deflection adjustment between the introduction tube 5 and the steel cable 9 and the set seat 6. The adjusting component is connected to the set seat 6 and the fixed head 8 respectively. When the second operating handle 2 is pushed and pulled to drive the steel cable 9 to drive the clamping forceps 11 to open and clamp foreign bodies in the bronchus, the medical staff can rotate the adjusting component to make the introduction tube 5 and the steel cable 9 deflect as a whole following the adjusting component, and then Adjusting the angle of the clamping forceps 11 in the bronchus can meet the needs of clamping foreign bodies in different positions. Different from the traditional angle adjustment, the entire foreign body extractor needs to be deflected and moved. The adjustment component can also play a certain limiting role after the angle adjustment, maintaining the position of the clamping forceps 11 after the angle adjustment, so that the medical staff can operate more conveniently and smoothly during the foreign body removal process; the positioning component is used to position the relative active position between the second operating handle 2 and the first operating handle 1. The positioning component is connected to the second operating handle 2. The opening and closing action of the clamping forceps 11 is achieved by the push-pull action of the second operating handle 2. The positioning component can position and lock the second operating handle 2 when the second operating handle 2 is pushed and pulled to different positions, indirectly maintaining the open and closed state of the clamping forceps 11, so that when the clamping forceps 11 clamps the foreign body, the position of the second operating handle 2 is locked to avoid the second operating handle 2 from being displaced again during the process of pulling out the foreign body, resulting in the clamping state of the clamping forceps 11 being lost, thereby ensuring the stability of the foreign body extractor during the process of removing the foreign body.

[0043] In this embodiment, if Figures 2 to 5As shown, a disc 19 is fixedly connected to the outside of the first connecting rod 17, a first movable cavity adapted to the shape of the disc 19 is opened in the first operating handle 1, a second spring 21 is fixedly connected to one end of the disc 19 and the first movable cavity, and a uniformly distributed first spring 20 is fixedly connected between the disc 19 and the other end of the first movable cavity. Pushing and pulling the second operating handle 2 can cause relative movement between the second operating handle 2 and the first operating handle 1. In this process, the second operating handle 2 can drive the disc 19 to slide in the first movable cavity through the first connecting rod 17, and The disc 19 drives the second spring 21 and the first spring 20 to contract or stretch. When no external force is applied to the second operating handle 2, the disc 19 can maintain a balanced state in the middle of the first active cavity under the action of the elastic force of the second spring 21 and the first spring 20, and indirectly maintain the initial state of the second operating handle 2. When the second operating handle 2 is in the initial state, the clamping forceps 11 also remains closed, so that the size of the end of the clamping forceps 11 is at the minimum value, which is smaller than the entrance of the introduction port 4, so that the clamping forceps 11, the steel cable 9 and the introduction tube 5 are easily inserted into the introduction port 4 on the collaborative bronchoscope 3.

[0044] In this embodiment, if Figures 3 to 10 As shown, the connecting assembly includes a slot 13 provided on the connecting head 10 and a connecting piece 26 symmetrically installed at the end of the second connecting rod 18, the end of the connecting piece 26 is fixedly connected with a connecting seat 27 adapted to the external shape of the connecting head 10, and the inner side of the connecting seat 27 is fixedly connected with a block 14 adapted to the shape of the slot 13, and the steel cable 9 is connected to the connecting head 10 through the connecting assembly. In this state, the connecting seat 27 on the connecting piece 26 is clamped on the outside of the connecting head 10, and the block 14 on the inner side of the connecting seat 27 is clamped in the slot 13 on the connecting head 10, and the connecting head 10 is connected to the connecting seat through the connecting head 10. The clamping connection between 27 forms a connection relationship between the steel cable 9 and the second connecting rod 18, so that the second connecting rod 18 can drive the steel cable 9 to realize the opening and closing of the clamping forceps 11 following the push-pull action of the second operating handle 2, and can separate and disassemble the introduction tube 5 and the steel cable 9 from the first operating handle 1 and the second operating handle 2 without affecting the normal operation of the clamping forceps 11 and the steel cable 9, so that the introduction tube 5, the steel cable 9 and the clamping forceps 11 can be used as disposable items to ensure medical hygiene, and the related structures such as the first operating handle 1 and the second operating handle 2 can be reused to reduce the waste of medical resources.

[0045] A second movable cavity adapted to the size of the second connecting rod 18 is provided between the set seat 6 and the first operating handle 1. The second movable cavity is connected to the first movable cavity. After the steel cable 9 and the second connecting rod 18 are connected through the connecting assembly, when the second operating handle 2 is pushed and pulled by medical staff and moves, the first connecting rod 17, the second connecting rod 18 and the structure of the connecting assembly will move together with the second operating handle 2. The second movable cavity is provided to provide space for the movement of these structures. A through opening 25 connected to the second movable cavity is provided on the outside of the set seat 6. A paddle 28 extending through the through opening 25 to the outside of the set seat 6 is fixedly connected. The through opening 25 can provide a channel for the paddle 28 to extend to the outside of the set seat 6. Paddle 28 can cause the connecting seat 27 located in the set seat 6 to be displaced, thereby increasing the distance between the two groups of connecting seats 27, so that the connecting head 10 can be inserted between the two groups of connecting seats 27. After releasing the paddle 28, the connecting seat 27 can be reset and connected to the connecting head 1 0 are butt-jointed to form a connection state of the connection assembly, a second weakened portion 31 is provided in the middle of the connection piece 26, the second weakened portion 31 is semicircular, and two ends of the second weakened portion 31 are symmetrically connected with support frames 32, and the support frames 32 are located at the opening of the second weakened portion 31. The thickness of the connection piece 26 at the second weakened portion 31 is thinner and the strength is weaker, so that the connection piece 26 can be deformed at the second weakened portion 31 after being subjected to external force, and when the paddle 28 is turned, the external force can be applied to the connection piece 26 through the connection seat 27, and then This causes the connecting piece 26 to deform at the second weakened portion 31, indirectly causing the connecting seat 27 at the end of the connecting piece 26 to be displaced, thereby increasing the distance between the two groups of connecting seats 27. When the connecting assembly is in a connected state, the support frames 32 located at both ends of the same second weakened portion 31 will press against each other, and then when the second operating handle 2 is pushed to move the connecting assembly, the support frames 32 press against each other to prevent the second weakened portion 31 from deforming and affecting the stability of the connection and fixation between the connecting seat 27 and the connecting head 10.

[0046] In this embodiment, if Figures 4 to 6As shown, the adjustment component includes a rubber ring 15 fixedly connected in the fixed head 8 and a sleeve groove 23 opened on the inner side wall of the set seat 6, the sleeve groove 23 is adapted to the shape of the rubber ring 15, and the ends of the set seat 6 and the fixed head 8 are both provided with inclined surfaces. The inclined surface at the end of the set seat 6 is located on the inner side of the set seat 6, so that the area value at the entrance of the end of the set seat 6 is larger, and the inclined surface at the end of the fixed head 8 is located on the outside of the fixed head 8, so that the area value at the end of the fixed head 8 is lower, which makes it easy to fix the head 8. Insertion into the set seat 6 facilitates the set of the fixed head 8 to the outside of the set seat 6. The steel cable 9 and the connecting head 10 are movably connected through the rotating shaft 12. A connecting cavity adapted to the end thickness value of the set seat 6 is opened in the fixed head 8. There are two groups of rubber rings 15. Both groups of rubber rings 15 are located in the connecting cavity. The outside of the rubber ring 15 is fixedly connected with uniformly distributed rubber sheets 16. The rubber sheet 16 is provided with a limiting groove 24 adapted to the shape of the rubber sheet 16. The fixed head 8 in the rotating adjustment assembly When the fixed head 8 is turned, the fixed head 8 can drive the introduction tube 5 and the steel cable 9 to deflect as a whole, thereby adjusting the angle of the clamping forceps 11 in the bronchus and meeting the requirements of the clamping forceps 11 for clamping foreign bodies at different positions in the bronchus after opening. In the process of adjusting the angle of the clamping forceps 11 in the bronchus by rotating the fixed head 8, the rubber ring 15 follows the rotation of the fixed head 8 and moves relative to the sleeve groove 23. After each deflection of a certain angle, the rubber sheet 16 will be embedded in the limit groove 24 at the corresponding position, thereby realizing auxiliary positioning of the fixed head 8, so that after the fixed head 8 is loosened, the adjusted angle of the clamping forceps 11 can be maintained, ensuring the stability of the clamping forceps 11 during the working process after the angle adjustment. The rotating shaft 12 between the connecting head 10 and the steel cable 9 makes the steel cable 9 and the connecting head 10 in an active connection relationship, so that the rotation of the steel cable 9 and the introduction tube 5 will not interfere with the connection relationship between the connecting head 10 and the connecting seat 27, avoiding interference between the work of the adjustment component and the work of the connection component.

[0047] In this embodiment, if Figure 2 and Figure 5 as well as Figure 8As shown, the positioning assembly includes an elastic plate 7 fixedly connected to the outside of the second operating handle 2, and the end of the elastic plate 7 is fixedly connected with a positioning head 29 facing the outside of the first operating handle 1. The outside of the first operating handle 1 is provided with a positioning groove 30 adapted to the shape of the positioning head 29. The elastic plate 7 is wavy, and a first weakened portion 22 is provided in the middle of the elastic plate 7. The wavy structure of the elastic plate 7 causes multiple notches to appear on the outside of the elastic plate 7. When the medical staff moves the elastic plate 7 with their fingers, the setting of the notches can better wrap the fingers of the medical staff who move the elastic plate 7. When the medical staff pushes and pulls the second operating handle 2, the medical staff can use the palm of the hand to hold the first operating handle 1 and insert the index finger into the second operating handle 2. In the annular structure, when a push-pull operation is required, the elastic plate 7 can be moved by the middle finger to drive the positioning assembly to work. The width and thickness of the first weakened portion 22 are both smaller than the width and thickness of the elastic plate 7. The setting of the first weakened portion 22 makes the elastic plate 7 thinner at the first weakened portion 22, thereby making the strength of the elastic plate 7 at the first weakened portion 22 weaker. When the elastic plate 7 is moved, the elastic plate 7 can more easily produce corresponding deformation at the first weakened portion 22. There are three groups of positioning grooves 30. The distance between the top positioning groove 30 and the bottom positioning groove 30 is the same as the length of the through opening 25. The positions of the three groups of positioning grooves 30 correspond to the three states of the positioning assembly. The positioning head 2 When the positioning head 29 is embedded in the middle positioning groove 30, the clamping clamp 11 is in a closed state, which can facilitate the passage of the clamping clamp 11 from the introduction port 4. When the positioning head 29 is embedded in the upper positioning groove 30, the clamping clamp 11 is in an open state. At this time, the clamping clamp 11 can be moved to the outside of the foreign object, and then the second operating handle 2 is pushed to drive the positioning head 29 on the elastic plate 7 to move to the lowest positioning groove 30, so as to keep the clamping clamp 11 closed and clamp the foreign object, and apply additional pressure to the clamping clamp 11 to further maintain the clamping state of the clamping clamp 11. After the clamping clamp 11 clamps the foreign object, the stability of the clamping state is ensured to prevent the foreign object from falling off. In the process of operating the second operating handle 2 to drive the steel cable 9 to push and pull, the elastic plate 7 is moved. The elastic plate 7 can be bent and deformed at the first weakened portion 22, and the positioning head 29 can be withdrawn from the positioning groove 30, thereby releasing the lock on the second operating handle 2. When the second operating handle 2 is pushed and pulled to other fixed points according to usage requirements, loosening the elastic plate 7 can form a snap-fitting relationship between the positioning head 29 and the positioning groove 30 at the corresponding position, and then the second operating handle 2 can be locked again, so that the opening and closing of the clamping forceps 11 can be locked by the positioning assembly after the pushing and pulling operation of the second operating handle 2 is achieved, so that the clamping forceps 11 can clamp the foreign body in the bronchus, and the clamping forceps 11 in the closed state can be locked during the clamping process to ensure the stability of the foreign body during the removal process.
