Technical Field
[0001] This utility model belongs to the field of medical device technology, specifically relating to a forceps for sealing bottles without a field of vision. Background Technology
[0002] Nuclear medicine examinations and treatments require the use of radiopharmaceuticals. These radiopharmaceuticals are mostly stored in sealed vials. Since these vials do not block radiation, they must be placed in heavy lead containers and sealed with lead stoppers during transport. When needed, the lead stopper is opened in the dispensing apparatus to extract the radiopharmaceutical from the sealed vial. After extraction, the vial must be removed from the lead container and placed in a dedicated recycling box.
[0003] Currently, long-handled tweezers are traditionally used to remove sealed bottles from lead containers. However, because the sealed bottle is some distance from the mouth of the lead container and the operating opening of the dispensing device is very small, the sealed bottle cannot be seen. Therefore, traditional tweezers are not easy to grasp the sealed bottle. Moreover, the tip of the tweezers is sharp and the mouth of the sealed bottle is round and smooth, so it is easy to drop after being grasped. This requires repeated grasping of the sealed bottle, which reduces work efficiency. Furthermore, repeated operation increases the time of exposure to high doses of radiation. The sealed bottle may fall into the gap of the dispensing device, and picking up the sealed bottle will also inevitably increase the radiation damage to the operator.
[0004] Therefore, how to provide a pair of pliers that can grip sealed bottles without a field of vision, making it easy to grasp the sealed bottles, preventing them from falling, and improving work efficiency is a technical problem that urgently needs to be solved by those skilled in the art.

The size of the radial opening is adapted to the size of the sealed bottle, and the elastic locking component is engaged with the sealed bottle through the radial opening.
[0007] A further technical solution of this utility model is as follows: the elastic snap-fit component includes: a snap-fit ring, which is made of metal, and a snap-fit groove is formed at the bottom end of the fixed cylinder along the circumferential direction of the fixed cylinder, and the snap-fit ring snaps into the snap-fit groove; a circular elastic membrane, which is made of elastic material, and the outer periphery of the circular elastic membrane is fixedly connected to the inner wall of the snap-fit ring, and a radial opening is formed in the middle of the circular elastic membrane, and the circular elastic membrane snaps into the sealed bottle through the radial opening.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Example 1
[0034] Please see Figure 1-2This embodiment provides a pliers for blind-clamping a sealed bottle without a field of vision. The sealed bottle is placed inside a lead container. The pliers include a pliers body 1, a fixed cylinder 2, and an elastic clamping member 3. The pliers body 1 includes a first clamping arm 11 and a second clamping arm 12, which are rotatably connected at the middle of the first clamping arm 11 and the middle of the second clamping arm 12. The first clamping arm 11 has a first hand-held end and a fixed end. The fixed cylinder 2 is hollow inside, with both ends open. The outer wall of the top of the fixed cylinder 2 is connected to the fixed end. The first clamping arm 11 is perpendicular to the central axis of the fixed cylinder 2, and the size of the fixed cylinder 2 is adapted to the internal size of the lead container. The elastic clamping member 3 is detachably disposed at the bottom end of the fixed cylinder 2. The elastic clamping member 3 is perpendicular to the central axis of the fixed cylinder 2, and a radial opening 4 is provided in the middle of the elastic clamping member 3. The size of the radial opening 4 is adapted to the size of the sealed bottle, and the elastic clamping member 3 is clamped to the sealed bottle through the radial opening 4. The first clamp arm 11 and the second clamp arm 12 are both made of metal. The diameter and height of the fixing cylinder 2 are slightly smaller than the internal diameter and height of the lead can, respectively. The size of the radial opening 4 is slightly smaller than the size of the sealed bottle. The radial opening 4 can be a central circular hole or a radial opening radiating outwards from the center. Figure 3 As shown.
[0035] This utility model provides a pair of pliers for blind-clamping sealed bottles without a field of vision. It can quickly and directly clamp sealed bottles containing radioactive drugs in lead containers without a field of vision, thus solving the problem of no operating field of vision. The pliers can firmly fix the sealed bottle, reduce the risk of the sealed bottle falling during the transfer, improve work efficiency, and is suitable for picking up and putting in sealed containers of radioactive drugs. The pliers include a plier body 1, a fixed cylinder 2, and a spring-loaded locking component 3. The middle part of the first plier arm 11 and the middle part of the second plier arm 12 of the plier body 1 are rotatably connected to form a plier body structure similar to scissors. The outer wall of the top of the fixed cylinder 2, which is hollow inside and open at both ends, is connected to the fixed end of the first plier arm 11. The first plier arm 11 is perpendicular to the central axis of the fixed cylinder 2. The size of the fixed cylinder 2 is adapted to the internal size of the lead can so that the fixed cylinder 2 is vertically fixed at the end of the fixed end of the first plier arm 11. The first plier arm 11 can be held vertically downward by moving the first hand-held end of the first plier arm 11 vertically downward so that the first plier arm 11 is vertically downward, so that the fixed cylinder 2 can be vertically inserted into the inside of the lead can to reach the sealed bottle inside the lead can. A removable elastic clamping piece 3 with radial openings 4 in the middle is installed at the bottom of the fixed cylinder 2. The elastic clamping piece 3 is perpendicular to the central axis of the fixed cylinder 2. The size of the radial openings 4 is adapted to the size of the sealed bottle. The elastic clamping piece 3 is engaged with the sealed bottle through the radial openings 4. When the fixed cylinder 2 is vertically placed into the lead can, the elastic clamping piece 3 at the bottom of the fixed cylinder 2 moves downward. The radial openings 4 contact the sealed bottle and squeeze the sealed bottle downward. Under the action of the squeezing force, the radial openings 4 open to fit around the sealed bottle and hold the sealed bottle in place under the action of elasticity. This fixes the sealed bottle inside the bottom of the fixed cylinder 2, making it easy to clamp the sealed bottle, preventing it from falling out, and improving work efficiency.
[0036] In some possible embodiments, the elastic snap-fit component 3 includes: a snap-fit ring 31, which is made of metal, and a snap-fit groove is formed at the bottom end of the fixed cylinder 2 along the circumferential direction of the fixed cylinder 2, and the snap-fit ring 31 snaps into the snap-fit groove; a circular elastic membrane 32, which is made of elastic material, and the outer periphery of the circular elastic membrane 32 is fixedly connected to the inner wall of the snap-fit ring 31, and a radial opening 4 is formed in the middle of the circular elastic membrane 32, and the circular elastic membrane 32 snaps into the sealed bottle through the radial opening 4.
[0037] This is because the snap-fit ring 31, made of metal, snaps into the snap-fit groove at the bottom end of the fixed cylinder 2 along the circumferential direction of the fixed cylinder 2. This snap-fit mechanism facilitates the disassembly of the snap-fit ring 31, allowing for easy replacement of the elastic snap-fit component 3 and reducing costs. The outer periphery of the circular elastic membrane 32, made of elastic material, is fixedly connected to the inner wall of the snap-fit ring 31. A radial opening 4 is provided in the center of the circular elastic membrane 32, through which the circular elastic membrane 32 connects to the sealed bottle. When the fixing cylinder 2 is vertically inserted into the lead can, the circular elastic membrane 32 at the bottom of the fixing cylinder 2 moves downward. The circular elastic membrane 32 contacts the sealing bottle and squeezes the sealing bottle downward, causing the radial opening 4 on the circular elastic membrane 32 to open under the squeezing force to fit around the sealing bottle and to lock the neck of the sealing bottle under the elastic force to fix the sealing bottle. Then, by moving the first clamp arm 11 upward, the sealing bottle can be taken out of the lead can, which makes it easier to clamp the sealing bottle, prevents it from falling, and improves work efficiency.
[0038] In some possible implementations, it also includes: a pusher 5, the second clamp arm 12 having a second hand-held end and a pusher end, one end of the pusher 5 being disposed at the pusher end, and the other end of the pusher 5 being disposed inside the fixed cylinder 2.
[0039] This is because one end of the pusher 5 is located at the pushing end of the second clamp arm 12, and the other end is placed inside the fixed cylinder 2. When the clamps pick up the sealed bottle and remove it from the lead container, the clamp body 1 can be closed by moving the first hand end downward and the second hand end upward. At this time, the fixed end upward and the pushing end downward also move towards each other, so that the pusher 5 at the pushing end moves downward inside the fixed cylinder 2 to push the sealed bottle at the bottom of the fixed cylinder 2. Under the action of the downward pushing force, the sealed bottle is released from the radial opening 4 and falls into the recycling box, so that the sealed bottle can be accurately and conveniently placed into the recycling box. The operation is convenient.
[0040] In some possible implementations, the pushing member 5 includes: a guide rail 51 fixed to the pushing end along the length direction of the second clamp arm 12; a slider 52 movably disposed on the guide rail 51; and a metal rod 53, one end of which is fixedly connected to the slider 52 and arranged perpendicularly between the second clamp arm 12, and the other end of which is placed inside the fixed cylinder 2; wherein, when the pushing end is close to the fixed end, the bottom end of the metal rod 53 contacts the circular elastic membrane 32, that is, the length of the metal rod 53 is slightly shorter than the height of the fixed cylinder 2.
[0041] This is because the lead can is about 20 cm in diameter, and the hole in the middle for placing the sealed bottle is about 5 cm in diameter. The lead can has a small opening diameter and a large depth. Therefore, the opening diameter and depth of the fixed cylinder 2, which is fitted to the lead can, are also small. A guide rail 51 is fixed along the length of the second clamp arm 12 on the pushing end. The slider 52 is movably mounted on the guide rail 51. One end of the metal rod 53 is fixedly connected to the slider 52 and is perpendicular to the second clamp arm 12. The other end is placed inside the fixed cylinder 2, allowing the metal rod 53 to slide along the length of the second clamp arm 12. This facilitates the metal rod 53 entering the fixed cylinder 2 and smoothly reaching the circular elastic membrane 32, so that the metal rod 53 can... The clamped sealed bottle is pushed into the recycling box. Specifically, during the closing of the clamp body 1, the fixed end moves upward and the pushing end moves downward to bring them closer together. First, the other end of the metal rod 53 abuts against the inner wall of the fixed cylinder 2. Then, as the pushing end continues to move downward, since the other end of the metal rod 53 abuts against the inner wall of the fixed cylinder 2, one end of the metal rod 53 will drive the slider 52 to move along the guide rail 51 to the end of the guide rail 51 near the second hand-held end. When the pushing end continues to move downward, the other end of the metal rod 53 continues to move downward along the inner wall of the fixed cylinder 2 to the sealed bottle, so as to push the sealed bottle downward and separate it from the circular elastic membrane 32. At this time, the bottom end of the metal rod 53 contacts the circular elastic membrane 32 to avoid damaging the circular elastic membrane 32.
[0042] In some possible implementations, the pusher 5 further includes: a first baffle 54, which is vertically fixed to the second clamp arm 12 and located on the side of the guide rail 51 near the second hand-held end; and a spring 55, one end of which is fixed to the side of the first baffle 54 and the other end of which is fixed to the side of the slider 52. When the spring 55 is in its natural state, the slider 52 is located at the end of the guide rail 51 away from the second hand-held end. When the pusher end is close to the fixed end, the end of the pusher end and the metal rod 53 are both located on the central axis of the fixed cylinder 2.
[0043] Those skilled in the art will understand that the first baffle 54 is vertically fixed on the second clamp arm 12 and located on the side of the guide rail 51 near the second hand-held end. One end of the spring 55 is fixed to the side of the first baffle 54, and the other end is fixed to the side of the slider 52. When the metal rod 53 and the slider 52 slide along the guide rail 51 toward the second hand-held end, under the restriction of the first baffle 54, the slider 52 squeezes the spring 55, causing the spring 55 to compress. When the other end of the metal rod 53 no longer abuts against the inner wall of the fixed cylinder 2, the slider 52 returns to its original position under the elastic force of the spring 55, and drives the metal rod 53 to return to its original position. When the spring 55 returns to its natural state, the slider 52 and the metal rod 53 also return to their original positions to the end of the guide rail 51 away from the second hand-held end, which is convenient for repeated use.
[0044] In some possible implementations, the pusher 5 further includes a second baffle 56, which is vertically fixed to the second clamp arm 12 and located on the side of the guide rail 51 away from the second hand-held end.
[0045] Those skilled in the art will understand that the second baffle 56 is vertically fixed to the second clamp arm 12 and located on the side of the guide rail 51 away from the second hand-held end, so as to prevent the slider 52 from falling off the side of the guide rail 51 away from the second hand-held end.
[0046] In some possible implementations, the fixing cylinder 2 has a frustum-shaped structure, and the diameter of the bottom surface of the fixing cylinder 2 is smaller than the diameter of the top surface of the fixing cylinder 2, so that the other end of the metal rod 53 can move downward along the inner wall of the fixing cylinder 2.
[0047] In some possible implementations, it also includes: a first annular handle 6, which is fixed to the first handheld end.
[0048] Those skilled in the art will understand that the first annular handle 6 fixed to the first hand end facilitates gripping of the first clamp arm 11.
[0049] In some possible implementations, it further includes: a second ring handle 7, which is fixed to the second hand-held end, and the size of the second ring handle 7 is larger than the size of the first ring handle 6.
[0050] Those skilled in the art will understand that the second ring handle 7, fixed to the second hand end, facilitates gripping the second clamp arm 12; the size of the second ring handle 7 is larger than the size of the first ring handle 6, and when gripping the clamps, the thumb can be placed inside the first ring handle 6, and the other two, three or four fingers can be placed inside the second ring handle 7, which facilitates gripping the first clamp arm 11 and the second clamp arm 12, so as to control the clamping and pushing of the sealed bottle.
[0051] In some possible implementations, the middle portion of the first clamp arm 11 and the middle portion of the second clamp arm 12 are rotatably connected by a pin 8.
[0052] As one of the assembly methods of this utility model, the first step is to install the slider 52 connected with the metal rod 53 and the guide rail 51 on the pushing end of the second clamp arm 12, and install the second baffle 56 at the end of the guide rail 51; the second step is to push the elastic snap-fit 3 into the snap-fit groove at the bottom of the fixed cylinder 2 and fix it, and then fix the fixed cylinder 2 to the fixed end of the first clamp arm 11 to complete the assembly.
