Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, in particular to a foreign body forceps for respiratory department. Background Art

[0002] Respiratory foreign body forceps is a medical device specially designed for use in respiratory surgery to clamp and remove foreign bodies in the respiratory tract. Respiratory foreign body forceps are usually used in conjunction with an endoscope to remove foreign bodies, stones or resected tissues in the respiratory tract.

[0003] The patent with announcement number CN211749887U discloses a foreign body forceps for respiratory department, including a fixed handle; the fixed handle is connected to a movable handle through a first pin shaft, the fixed handle is connected to a catheter, the movable handle is connected to a pull rod, a first clamp body is arranged at the front end of the catheter, the pull rod is connected to a second clamp body through a third pin shaft, the first clamp body and the second clamp body are connected through a second pin shaft, the first clamp body and the second clamp body are both provided with a serrated clamp, the serrated clamp includes a first serration, a second serration, a third serration and a fourth serration distributed from left to right, and a clamping piece is arranged at both ends of the serrated clamp; a plurality of hemispherical spherical clamps are connected on the same side of the first clamp body and the second clamp body through a connecting rod; the utility model can clamp ordinary-shaped and spherical foreign bodies, which is convenient for medical staff to operate.

[0004] However, the above technical solution still has the following deficiencies in practical application: Medical staff hold the handles and insert the two clamps into the patient's respiratory tract, then use the two clamps to clamp the foreign body and then remove the foreign body. When the foreign body is long and sharp, such as fish bones, pins, etc., the foreign body may scrape the respiratory tract during the removal process. Moreover, when the foreign body is sharp, it is easy to puncture the respiratory mucosa during the removal process, causing discomfort to the patient. Moreover, when using clamps to clamp the foreign body, if the foreign body is soft and has a smooth surface, the foreign body may slip from the clamps during the removal process, affecting the smooth removal of the foreign body. Moreover, when the gap between the soft foreign body and the respiratory tract is small, it is inconvenient for the clamps to extend into the gap between the foreign body and the respiratory tract, resulting in a smaller contact area between the clamps and the foreign body when clamping the foreign body, affecting the firmness of the clamping and causing the foreign body to fall off.

[0017] The beneficial effects of the present invention are as follows: 1. The respiratory foreign body forceps described in the present invention utilize a traction-type rotating mechanism. When the foreign body is a long and sharp foreign body such as a fish bone or a pin, the foreign body is clamped between two rotating blocks and contacts with an anti-skid pad, which can prevent the foreign body from slipping. Then, the pull ring is pulled to move the traction rope and drive the rack 1 to slide on the limit rod. The spring is stretched, and the gear 1 and the rotating block rotate at the same time to rotate the foreign body. When the foreign body rotates, its sharp ends will move away from the inner wall of the respiratory tract until the foreign body and the sleeve remain parallel.

[0018] 2. The respiratory foreign body forceps described in the present invention utilize a drilling assembly. When a foreign body is clamped by the clamp and is not firm enough, the pull block 2 is manually pushed to make the rod body 3 slide on the mounting plate, and the L-shaped block moves, and the bevel gear 1 can be rotated under the cooperation of the rack 2 and the gear 2, and the bevel gear 2 and the telescopic rod also rotate synchronously. When the telescopic rod rotates, the cone head approaches the foreign body and drills into the foreign body, and can be plugged into the foreign body. Then, the pull block 1 is rotated to make the rod body 2 and the worm rotate at the same time, so that the worm gear and the cone head rotate at the same time. When the cone head rotates inside the foreign body, it can form a hooked state with the inside of the foreign body. At this time, the clamp is taken out again to avoid the foreign body slipping from the clamp, thereby ensuring the firmness of the foreign body and improving the efficiency of foreign body removal.

[0019] 3. With the foreign body forceps for respiratory medicine described in the present invention, when medical staff hold the forceps handle, they can put their fingers through the finger ring to hold the forceps. Under the action of the finger ring, the range of movement of the fingers is limited, avoiding the situation where the smooth removal of foreign bodies is affected by finger sliding.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a respiratory foreign body forceps, comprising a forceps handle 1, a connecting block 4 is fixedly connected to the upper end of the forceps handle 1, a mounting plate 3 is fixedly connected to the upper end of the connecting block 4, a sleeve 5 is fixedly connected to the middle of the upper end surface of the mounting plate 3, and clamps 6 are rotatably arranged on both sides of the upper end of the sleeve 5, and a traction-type rotating mechanism for adjusting the angle of the foreign body is also arranged on the clamp 6; The traction type rotating mechanism comprises a rotating block 14 rotatably arranged on one side of the upper end of the clamp 6, and an anti-slip pad 15 is arranged on one side of the rotating block 14; The sleeve 5 is also provided with a drilling assembly for hooking foreign objects, and the drilling assembly includes a telescopic rod 31 slidably connected to the middle part of the upper end of the sleeve 5, and a cone head 12 is rotatably provided on the upper end of the telescopic rod 31.

[0025] In this embodiment, Figure 1 , Figure 3 , Figure 4 , Figure 6-Figure 9 As shown, one end of the clamp 6 is fixedly connected to a connecting rod 1 7, one end of the connecting rod 1 7 is rotatably provided with a connecting rod 2 8, and one end of the connecting rod 2 8 is rotatably provided with a sliding block 9.

[0026] The lower end of the slider 9 is fixedly connected to a rod body 10, the rod body 10 is slidably connected to the mounting plate 3, and the lower end of the rod body 10 is fixedly connected to a pull block 3 27.

[0027] A transmission chamber 32 is provided at the upper end of one side clamp 6, one end of the rotating block 14 is fixedly connected to a gear 17, the gear 17 is rotatably connected to the clamp 6, one side of the inner wall of the transmission chamber 32 is fixedly connected to a limit rod 19, the limit rod 19 is plugged and slidably connected to a rack 18, and the gear 17 and the tooth blocks on the rack 18 are meshed with each other.

[0028] One end of the rack 18 is fixedly connected to a spring 20 , and the other end of the spring 20 is fixedly connected to the inner wall of the transmission cavity 32 .

[0029] One end of the rack 18 is fixedly connected with a traction rope 16 , the traction rope 16 penetrates and is slidably connected with one side of the clamp 6 and the mounting plate 3 , and the end of the traction rope 16 is fixedly connected with a pull ring 22 .

[0030] Specifically, when the existing respiratory foreign body forceps are used, the medical staff holds the handle and extends the two clamps 6 into the patient's respiratory tract, and then uses the two clamps 6 to clamp the foreign body, and then removes the foreign body. When the foreign body is long and sharp, such as fish bones, pins, etc., the foreign body may scratch the respiratory tract during the removal process. Moreover, when the foreign body is sharp, it is easy to pierce the respiratory mucosa during the removal process, causing discomfort to the patient. Therefore, in order to avoid the above problems, when using the present embodiment, the medical staff holds the clamp handle 1 and extends the clamp 6 into the patient's respiratory tract. When the foreign body is between the two clamps 6, the pull block 3 27 is pulled to move the rod body 10 and the slider 9 at the same time, and the connecting rod 1 7 and the connecting rod 2 8 rotate at the same time, so that the two clamps 6 rotate in different directions at the same time, so that the foreign body can be clamped, and then the clamp 6 is moved out of the patient's respiratory tract to achieve the removal of the foreign body. When the foreign body is a long and sharp foreign body such as a fish bone or a pin, the foreign body is clamped between the two rotating blocks 14 and contacts the anti-skid pad 15. The anti-skid pad 15 can prevent the foreign body from slipping, and then the pull ring 22 is pulled to move the traction rope 16 and drive the rack 18 to slide on the limit rod 19. The spring 20 is stretched, and the gear 17 and the rotating block 14 rotate at the same time to rotate the foreign body. When the foreign body rotates, its sharp ends will move away from the inner wall of the respiratory tract until the foreign body and the sleeve 5 remain parallel. At this time, the foreign body can be taken out to avoid scratching the foreign body and the respiratory tract, which may cause the foreign body to pierce the respiratory mucosa during the removal process and cause discomfort to the patient, thereby further improving safety.

[0031] In this embodiment, Figure 2 , Figure 4 , Figure 5 As shown, a rod body 23 is slidably connected to one side of the mounting plate 3, a pull block 25 is fixedly connected to the lower end of the rod body 23, the rod body 23 penetrates and is rotatably connected to the telescopic rod 31, a worm 11 is fixedly connected to the upper end of the rod body 23, a worm wheel 13 is fixedly connected to one end of the cone head 12, and the worm 11 and the worm wheel 13 are meshed with each other.

[0032] The lower end of the telescopic rod 31 is sleeved and fixedly connected with an L-shaped block 33, one side of the lower end of the L-shaped block 33 is fixedly connected with two rod bodies 3 24, the rod body 3 24 is slidably connected to one side of the mounting plate 3, and the lower end of the rod body 3 24 is fixedly connected with a pull block 26.

[0033] The lower end of the telescopic rod 31 is sleeved and fixedly connected with a bevel gear 28, and a bevel gear 21 is rotatably provided on one side of the lower end of the L-shaped block 33, and the bevel gear 21 and the bevel gear 28 are meshed with each other. One end of the bevel gear 21 is fixedly connected with a gear 2 30, and one side of the upper end surface of the inner cavity of the sleeve 5 is fixedly connected with a rack 29, and the rack 29 and the gear 2 30 are meshed with each other.

[0034] Specifically, when the existing respiratory foreign body forceps are used, when the clamp 6 is used to clamp the foreign body, if the foreign body is relatively soft and has a smooth surface, the foreign body may slip from the clamp 6 during the removal process, affecting the smooth removal of the foreign body. In addition, when the gap between the soft foreign body and the respiratory tract is small, it is inconvenient for the clamp 6 to extend into the gap between the foreign body and the respiratory tract, resulting in a small contact area between the clamp 6 and the foreign body when clamping the foreign body, affecting the firmness of the clamping, and causing the foreign body to fall off. Therefore, in order to solve the above problems, when the present embodiment is in use, when a soft foreign object is clamped by the clamp and is not firm enough, the pull block 26 is manually pushed to make the rod body 3 24 slide on the mounting plate 3, and the L-shaped block 33 moves, and the bevel gear 1 21 can be rotated under the cooperation of the rack 29 and the gear 2 30, and the bevel gear 28 and the telescopic rod 31 also rotate synchronously. When the telescopic rod 31 rotates, the cone head 12 approaches the foreign object and drills into the foreign object, and can be plugged into the foreign object. Then, the pull block 1 25 is rotated again, so that the rod body 23 and the worm 11 can be rotated at the same time, so that the worm wheel 13 and the cone head 12 can be rotated at the same time. When the cone head 12 rotates inside the foreign object, it can form a hooked state with the inside of the foreign object. At this time, the clamp 6 can be taken out again, so as to avoid the foreign object from slipping from the clamp 6, thereby ensuring the firmness of the foreign object and improving the efficiency of foreign object removal.

[0035] In this embodiment, Figure 1 and Figure 2 As shown, finger rings 2 are fixedly connected to both sides of the pliers handle 1.

[0036] Specifically, when the medical staff holds the forceps handle 1, they can pass their fingers through the finger ring 2 to hold the forceps, so that the finger ring 2 can limit the range of movement of the fingers, thereby avoiding the situation where the smooth removal of foreign bodies is affected by finger sliding.

[0037] Working principle: when the medical staff holds the forceps handle 1, they can pass their fingers through the finger ring 2 to hold the forceps. Under the action of the finger ring 2, the range of movement of the fingers is limited, avoiding the situation where the smooth removal of foreign bodies is affected by the sliding of the fingers. The clamps 6 are extended into the patient's respiratory tract. When the foreign body is between the two clamps 6, the pull block 3 27 is pulled to move the rod body 10 and the slider 9 at the same time, and the connecting rod 1 7 and the connecting rod 2 8 are rotated at the same time, so that the two clamps 6 rotate in different directions at the same time, so that the foreign body can be clamped, and then The clamp 6 is moved out of the patient's respiratory tract to remove the foreign body. When the foreign body is a long and sharp foreign body such as a fish bone or a pin, the foreign body is clamped between the two rotating blocks 14 and contacts the anti-skid pad 15, which can prevent the foreign body from slipping. Then, the pull ring 22 is pulled to move the traction rope 16 and drive the rack 18 to slide on the limit rod 19. The spring 20 is stretched, and the gear 17 and the rotating block 14 rotate at the same time to rotate the foreign body. When the foreign body rotates, its sharp ends will be away from the inner wall of the respiratory tract. Until the foreign body is parallel to the sleeve 5, at this time, the foreign body is taken out, which can avoid the foreign body from scratching the respiratory tract during the removal process, causing the foreign body to pierce the respiratory mucosa and cause discomfort to the patient, further improving safety. When the soft foreign body is clamped by the clamp and is not firm enough, the pull block 26 is manually pushed to make the rod body 3 24 slide on the mounting plate 3, and the L-shaped block 33 moves, so that the bevel gear 1 21 can be rotated under the cooperation of the rack 2 29 and the gear 2 30, and the bevel gear 2 28 and the telescopic rod 31 also rotates synchronously. When the telescopic rod 31 rotates, the cone head 12 approaches the foreign object and drills into the foreign object, so as to be plugged into the foreign object. Then, the pull block 1 25 is rotated to make the rod body 23 and the worm 11 rotate at the same time, so as to make the worm wheel 13 and the cone head 12 rotate at the same time. When the cone head 12 rotates inside the foreign object, it can form a hooked state with the inside of the foreign object. At this time, the clamp 6 is taken out to avoid the foreign object from slipping off the clamp 6, thereby ensuring the firmness of the foreign object and improving the efficiency of taking out the foreign object. Thus, by utilizing the traction type rotating mechanism, when the foreign body is a long and sharp foreign body such as a fish bone or a pin, the foreign body is clamped between the two rotating blocks 14 and contacts the anti-skid pad 15, which can prevent the foreign body from slipping. Then, the pull ring 22 is pulled to move the traction rope 16 and drive the rack 18 to slide on the limit rod 19, the spring 20 is stretched, and the gear 17 and the rotating block 14 rotate at the same time to rotate the foreign body. When the foreign body rotates, its sharp ends will move away from the inner wall of the respiratory tract until the foreign body and the sleeve 5 are kept parallel. At this time, the foreign body can be taken out, which can avoid the foreign body stabbing the respiratory mucosa due to the scratching between the foreign body and the respiratory tract during the removal process, and the patient will feel uncomfortable, thereby further improving safety. Therefore, by utilizing the drilling assembly, when the foreign object is clamped by the clamp and is not firm enough, the pull block 2 is manually pushed to make the rod body 3 slide on the mounting plate, and the L-shaped block moves, and the bevel gear 1 can be rotated with the cooperation of the rack 2 and the gear 2, and the bevel gear 2 and the telescopic rod also rotate synchronously. When the telescopic rod rotates, the cone head approaches the foreign object and drills into the foreign object, and can be plugged into the foreign object. Then, the pull block 1 is rotated again, so that the rod body 2 and the worm gear are rotated at the same time, so that the worm gear and the cone head are rotated at the same time. When the cone head rotates inside the foreign object, it can form a hooked state with the inside of the foreign object. At this time, the clamp is taken out again to avoid the foreign object from slipping from the clamp, thereby ensuring the firmness of the foreign object and improving the efficiency of foreign object removal.
