Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an intestinal polyp collector. Background Art

[0002] Patients with gastrointestinal polyps need to use an intestinal polyp collector to collect the intestinal polyps after intestinal polypectomy under colonoscopy, and then transfer the intestinal polyps for biopsy.

[0003] The Chinese utility model patent with application number CN202120911130.6 discloses a polyp collector for endoscopy. When using this solution, first install a trachea on the central tube and the collecting tube on the cup cover. The trachea on the collecting tube is connected to the endoscope, and the trachea on the central tube is connected to the suction pump. When in use, the pneumatic suction pump draws the removed polyps into the collecting cavity through the collecting tube. When the polyps are attracted, the waste liquid in the patient's intestines will also be attracted into the collecting cavity, and the waste liquid in the collecting cavity flows to the bottom of the collecting cup body through the leakage hole. When the polyps are collected, unplug the trachea on the central tube and the collecting tube, pour out the waste liquid at the bottom of the collecting cup body through the central tube, and then add formaldehyde solution from the central tube. After the addition is completed, fit the sealing cap to the central tube and the collecting tube, seal the central tube and the collecting tube, and then transfer them for biopsy. Although this solution can collect polyps, it still has the following disadvantages:

[0004] When adding formaldehyde solution into the collection cup body, the portion at the bottom of the collection cup body used to hold waste liquid will also hold a large amount of formaldehyde solution, that is, the space used to hold waste liquid will also hold a large amount of formaldehyde solution. A large amount of formaldehyde solution needs to be added to the collection cup body to soak the polyp specimen, resulting in a large amount of formaldehyde solution used, which in turn leads to high subsequent processing costs for the discarded formaldehyde solution. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0021] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] like Figure 1 and Figure 2As shown, the utility model is an intestinal polyp collector, comprising a cup body 1, a top cover 2, a collecting tube 3, a leakage hole 4, a sealing part, a waste liquid cup 5 and an air outlet pipe 6. The upper end of the cup body 1 is open, the top cover 2 is fixedly arranged on the cup body 1, the top cover 2 is used to seal the opening at the upper end of the cup body 1, the collecting tube 3 is arranged on the top cover 2, the inner cavity of the collecting tube 3 is connected to the inner cavity of the cup body 1, there are multiple leakage holes 4, and multiple leakage holes 4 are arranged on the bottom wall of the cup body 1, the sealing part is arranged at the lower end of the cup body 1, the sealing part is used to seal all the leakage holes 4, the waste liquid cup 5 is detachably fixedly connected to the cup body 1, the waste liquid cup 5 is used to receive the waste liquid leaking from the leakage hole 4, the air outlet pipe 6 is arranged on the upper part of the waste liquid cup 5, and the inner cavity of the air outlet pipe 6 is connected to the inner cavity of the waste liquid cup 5.

[0024] When the intestinal polyp collector described in the utility model is in the initial state, the blocking part does not close the leakage hole 4. When using the intestinal polyp collector described in the utility model, a connecting tube is used to connect the collection tube 3 and the channel for discharging intestinal polyps in the colonoscope, that is, one end of the connecting tube is connected to the collection tube 3, and the other end is connected to the channel for discharging intestinal polyps in the colonoscope. Another connecting tube is used to connect the air outlet pipe 6 and the suction pump, that is, one end of the other connecting tube is connected to the air outlet pipe 6, and the other end is connected to the suction pump. The suction pump can be a suction pump with model KV-6. Then start the suction pump, and the suction pump sucks out the air in the waste liquid cup 5 and the cup body 1, so that negative pressure is formed in the waste liquid cup 5 and the cup body 1. Under the action of negative pressure, the intestinal polyps cut off from the patient's intestine can be sucked into the cup body 1 through the channel for discharging intestinal polyps in the colonoscope, the connecting tube and the collection tube 3 in turn. The waste liquid sucked into the cup body 1 together with the polyps can flow downward through the plurality of leakage holes 4 into the waste liquid cup 5 for collection, while the polyps remain in the cup body 1 .

[0025] After the polyps are collected in the cup body 1, stop the suction pump. Remove the one connecting tube from between the collecting tube 3 and the colonoscope, and remove the other connecting tube from between the air outlet pipe 6 and the suction pump. Then remove the waste liquid cup 5 containing waste liquid from the cup body 1, and seal all the leakage holes 4 by the sealing part. Then, the formaldehyde solution can be added to the cup body 1 through a syringe. When adding the formaldehyde solution, the formaldehyde solution is sucked by a syringe, and the formaldehyde solution is injected into the cup body 1 through the collecting tube 3, so that the formaldehyde solution submerges and soaks the polyp specimen in the cup body 1. Then, a soft rubber plug can be used to plug the collecting tube 3 to seal the collecting tube 3. Finally, the polyps in the cup body 1 can be transferred for biopsy.

[0026] Due to the adoption of the above technical scheme, before adding the formaldehyde solution, the leakage hole 4 is in a closed state, and the formaldehyde solution entering the cup body 1 will not enter the waste liquid cup 5, that is, the formaldehyde solution entering the cup body 1 will not enter the space for accommodating waste liquid, which can reduce the amount of formaldehyde solution used and the subsequent treatment cost of the discarded formaldehyde solution.

[0027] The outer circumferential surface of the upper end of the cup body 1 is provided with an external thread, the top cover 2 includes a ring and a top plate fixed to the upper end of the ring, the top plate closes the upper end of the ring, the ring is provided with an internal thread, and the ring is threadedly connected to the outer surface of the upper end of the cup body 1. With this structure, the top cover 2 can be fixed on the cup body 1 and close the opening of the upper end of the cup body 1, and the collecting pipe 3 is arranged on the top plate.

[0028] The plurality of leakage holes 4 are arranged along the circumferential direction; the blocking portion includes a bottom cover, which is rotatably connected to the lower end of the cup body 1, and the bottom cover abuts against the lower side of the cup body 1. A drainage hole 7 is formed on the bottom cover at a position opposite to each leakage hole 4. When the bottom cover is rotated a certain angle at the lower end of the cup body, each drainage hole 7 is completely offset from the leakage hole 4 opposite to it; the waste liquid cup 5 is detachably fixedly connected to the bottom cover.

[0029] When the intestinal polyp collector of the utility model is in the initial state, the multiple drainage holes 7 are aligned with the multiple leakage holes 4 one by one, and the blocking portion is in a state of not sealing the leakage holes 4. In the process of sucking the polyps cut from the patient's intestine into the cup body 1, the waste liquid sucked into the cup body 1 together with the polyps can flow downward into the waste liquid cup 5 through the multiple leakage holes 4 and the multiple drainage holes 7 for collection.

[0030] After the waste liquid cup 5 containing waste liquid is removed from the cup body 1, the bottom cover is rotated at a certain angle at the lower end of the cup body 1, so that each of the drainage holes 7 is completely staggered from the leakage hole 4 directly opposite to it, and the bottom cover abuts against the lower side of the cup body 1. At this time, all the leakage holes 4 can be closed. With this structure, the blocking part can block all the leakage holes 4.

[0031] The bottom cover is rotatably connected to the lower end of the cup body 1 , and the waste liquid cup 5 is detachably fixedly connected to the bottom cover. With this structure, the waste liquid cup 5 can be indirectly detachably fixedly connected to the cup body 1 .

[0032] In this embodiment, the outer circumferential surface of the lower part of the cup body 1 is recessed inward to form an annular groove 8; the bottom cover includes a first connecting ring 9, a sealing ring 10 and a cover plate, the first connecting ring 9 is arranged on the lower end of the cup body 1, the first connecting ring 9 is rotatably fitted with the lower end of the cup body 1, the sealing ring 10 is fixed on the first connecting ring 9, the sealing ring 10 is rotatably fitted in the annular groove 8, the cover plate is fixed on the lower end of the first connecting ring 9, and the cover plate closes the lower end of the first connecting ring 9; the upper side surface of the cover plate abuts against the lower side surface of the cup body 1, and the drainage hole 7 is formed on the cover plate.

[0033] Since the first connecting ring 9 is rotatably fitted to the lower end of the cup body 1, and the sealing ring 10 is rotatably fitted in the annular groove 8, with this structure, the bottom cover can be rotatably connected to the lower end of the cup body 1. The sealing ring 10 can seal the gap between the inner surface of the first connecting ring 9 and the outer surface of the cup body 1.

[0034] In this embodiment, the cover plate includes a circular plate 11 and a soft elastic rubber layer 12. The circular plate 11 is fixed to the lower end of the first connecting ring 9. The circular plate 11 closes the lower end of the first connecting ring 9. The soft elastic rubber layer 12 is fixed to the upper surface of the circular plate 11; the upper side of the soft elastic rubber layer 12 abuts against the lower side of the cup body 1, and the drainage hole 7 passes through the lower side of the circular plate 11 and the upper side of the soft elastic rubber layer 12.

[0035] The soft elastic rubber layer 12 has a good sealing effect, so that after each of the drainage holes 7 is completely staggered from the leakage hole 4 directly facing it, the soft elastic rubber layer 12 can have a good sealing effect on the leakage hole 4. Thus, the blocking part can have a good sealing effect on the leakage hole 4.

[0036] In this embodiment, the waste liquid cup 5 is open at the upper end and closed at the lower end, and the inner surface of the upper end of the waste liquid cup 5 is provided with an internal thread; the bottom cover also includes a second connecting ring 13 fixedly arranged on the lower side of the cover plate, the edge of the second connecting ring 13 is fixedly connected to the edge of the cover plate, and the outer peripheral surface of the second connecting ring 13 is provided with an external thread, and the second connecting ring 13 is threadedly connected to the upper end of the waste liquid cup 5.

[0037] The second connecting ring 13 is threadedly connected to the upper end of the waste liquid cup 5, that is, the upper end of the waste liquid cup 5 is threadedly connected to the second connecting ring 13. With this structure, the waste liquid cup 5 can be detachably fixedly connected to the bottom cover. By means of threaded connection, the inner circumference of the waste liquid cup 5 and the outer circumference of the second connecting ring 13 have good airtightness.

[0038] In this embodiment, the intestinal polyp collector described in the utility model further includes a screw cap 14 , in which an internal thread is provided. The screw cap 14 is used for being threadedly connected to the outer surface of the second connecting ring 13 .

[0039] After the waste liquid cup 5 is removed from the second connecting ring 13, the screw cap 14 is threadedly connected to the outer surface of the second connecting ring 13 (see Figure 3 As shown), the lower end of the second connecting ring 13 can be closed, which can reduce the possibility of residual waste liquid on the lower side of the cover plate or the inner surface of the second connecting ring 13 dripping out and contaminating the floor of the operating room.

[0040] The above embodiments only express the preferred implementation of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
