Description

Technical Field

[0001] The invention relates to the technical field of diverticular fecal stone cleaning tools, in particular to a tool for removing intestinal diverticular fecal stone incarceration. Background Art

[0002] During colonoscopy, multiple diverticula of the large intestine are often found in patients with constipation. Fecal stones can be found in some diverticula. If fecal stones are incarcerated for a long time, it is easy to induce diverticulitis and cause abdominal pain. At present, there is no special instrument in clinical practice. Foreign body forceps, snares, and biopsy forceps cannot be used to remove them because the characteristics of diverticula are that the bottom is large and the mouth is small. The size of the fecal stones exposed at the diverticula mouth is much smaller than the actual size.

[0003] Currently, there is no special instrument for removing fecal stones from diverticula in clinical practice. Because the characteristics of diverticula are large bottom and small opening, the size of fecal stones exposed at the diverticula opening is much smaller than the actual size. Summary of the invention

[0004] In view of this, in order to solve the technical problem that there is no special instrument for removing fecal stones in diverticula at present, on the one hand, the present invention provides a tool for removing fecal stones in intestinal diverticula, which is modified on the basis of the original disposable papillary sphincterotomy knife, and removes one side of the cavity for injecting contrast agent, and only needs one water injection channel. Water is injected through the water injection port, and the fecal stones are flushed out of the diverticula by strong water pressure. The tool has a simple structure and is easy to operate. The tip of the sheath can be bent to change the angle, and has a wide range of applications, which improves work efficiency.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A tool for removing intestinal diverticulum fecal stone incarceration, comprising:

[0007] A sheath tube, the head end of which has a water outlet and can be bent to adjust the angle;

[0008] The water injection port is connected with the water outlet through a water injection channel in the sheath tube.

[0009] Preferably, it also includes:

[0010] A sliding pull ring, located at the rear end of the sheath tube;

[0011] A push rod, located outside the sliding pull ring;

[0012] An inner core, one end of which is connected to the head end of the sheath tube, and the other end of which is connected to the push rod or the sliding pull ring;

[0013] The relative sliding of the pushing rod and the sliding pull ring can drive the inner core to drive the head end of the sheath tube to bend.

[0014] Preferably, when the inner core is connected to the pushing rod, the sliding pull ring is connected to the rear end of the sheath tube.

[0015] Preferably, when the inner core is connected to the sliding pull ring, the pushing rod is connected to the rear end of the sheath tube.

[0016] Preferably, the sheath is made of flexible medical polymer material.

[0017] Preferably, the flexible medical polymer material is medical grade polyethylene.

[0018] Preferably, it also includes:

[0019] A syringe is used to communicate with the water injection port.

[0020] On the other hand, the present invention also provides a method for using the above-mentioned intestinal diverticulum fecal stone removal tool, after the head end of the sheath is inserted into the bottom of the diverticulum, water is injected through the water injection port to flush the fecal stone out of the diverticulum.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The intestinal diverticulum fecal stone impaction removal tool involved in the present invention is an innovative improvement based on the traditional disposable papillary sphincterotomy. Specifically, we removed the side cavity channel for injecting contrast agent and simplified the design, so that the tool can complete its function with only one water injection channel. By injecting an appropriate amount of water through this water injection port, the fecal stone impacted in the intestinal diverticulum can be effectively flushed out with the help of the strong water pressure generated. The design concept of this tool is to pursue structural simplicity and convenience of operation. The head of the sheath is designed to be flexible and can adjust the angle as needed, thereby greatly broadening its scope of application. In addition, this improved tool significantly improves work efficiency in actual use and brings convenience to medical operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 As shown, the present invention provides a tool for removing fecal stones from intestinal diverticulum, which can be modified on the basis of a disposable papillary sphincterotomy knife, and the cavity on one side of the knife for injecting contrast agent is eliminated, and only one water injection channel is retained. By injecting water into the water injection port 3, the fecal stone is removed from the diverticulum by using strong water pressure. It includes:

[0029] The sheath tube 1 is a medical device, and its design feature is that the head end 2 has a water outlet and can be flexibly bent to adjust the angle. This design allows the sheath tube 1 to adjust the direction and position of its head end 2 according to different medical needs during use. Through this bending and adjusting angle function, the sheath tube 1 can be applied to diverticula of various shapes and positions, especially for the cleaning of fecal stones in diverticula, and has extremely high applicability. The flexibility and adaptability of this device greatly improve the efficiency and safety of medical operations, allowing doctors to more accurately locate and remove fecal stones in diverticula during endoscopic surgery, thereby effectively alleviating the patient's pain and shortening the recovery time.

[0030] The design of the water injection port 3 cleverly utilizes the water injection channel in the sheath tube 1 to achieve connectivity with the water outlet. When cleaning work is required, by injecting a proper amount of water into the water injection port 3, the water will flow smoothly to the water outlet through the water injection channel and spray out from there. This process utilizes the principle of water pressure to effectively clean and remove blockages such as fecal stones.

[0031] The present invention also includes:

[0032] A sliding pull ring 5 is located at the rear end of the sheath tube 1;

[0033] A push rod 4 is located outside the sliding pull ring 5;

[0034] An inner core 6, one end of which is connected to the head end 2 of the sheath tube 1, and the other end of which is connected to the push rod 4 or the sliding pull ring 5;

[0035] The relative sliding of the push rod 4 and the sliding pull ring 5 can drive the inner core 6 to drive the head end 2 of the sheath tube 1 to bend.

[0036] In the present invention, when the inner core 6 is connected to the push rod 4 , the sliding pull ring 5 is connected to the rear end of the sheath tube 1 .

[0037] In the present invention, when the inner core 6 is connected to the sliding pull ring 5 , the push rod 4 is connected to the rear end of the sheath tube 1 .

[0038] In the above two methods of realizing bending of the head end 2 of the sheath tube 1 provided by the present invention, one is that one end of the inner core 6 is connected to the push rod 4, and the head end 2 of the sheath tube 1 is driven to bend by the movement of the push rod 4; the other is that the head end 2 of the sheath tube 1 is driven to bend by the movement of the sliding pull ring 5. The most suitable implementation method can be selected according to the actual situation.

[0039] In addition, the present invention also takes into account the convenience and safety of operation. In the design, the sliding pull ring 5 and the push rod 4 are both in a shape and material that is easy to hold, ensuring that the operator can stably control the device during use.

[0040] In the present invention, the bending angle of the sheath tube 1 can be precisely controlled by the scale marks on the push rod 4 or the sliding pull ring 5, so as to meet the precise requirements of different surgeries or operations.

[0041] In the present invention, the length of the sheath tube 1 can be selected according to actual needs.

[0042] In summary, the present invention not only improves the flexibility and accuracy of the operation of the sheath tube 1, but also ensures the safety and reliability of the operation.

[0043] In the present invention, the sheath tube 1 described uses a highly flexible medical grade polymer material as its main material. This material is selected to ensure that the sheath tube 1 can provide sufficient flexibility and adaptability in medical applications, while ensuring its biocompatibility to adapt to the special requirements of the internal environment of the human body. By using this special medical polymer material, the sheath tube 1 can effectively perform medical operations without causing discomfort or potential harm to the patient.

[0044] In the present invention, the flexible medical polymer material involved particularly refers to medical-grade polyethylene, which is widely used in the medical field due to its unique physical and chemical properties, especially in the manufacture of various medical devices and supplies. Due to its good biocompatibility and flexibility, it can meet the medical industry's high requirements for safety and comfort.

[0045] The present invention also includes some other important components:

[0046] The syringe is designed to be connected with the water injection port 3 to facilitate the injection and discharge of liquid.

[0047] On the other hand, the present invention also provides a method for using the above-mentioned intestinal diverticulum fecal stone removal tool, after the head end 2 of the sheath tube 1 is inserted into the bottom of the diverticulum, water is injected through the water injection port 3 to flush the fecal stone out of the diverticulum. The details are as follows:

[0048] 1. Equipment preparation

[0049] Equipment Assembly:

[0050] Insert the inner core 6 into the sheath tube 1 and ensure that the end of the inner core 6 is connected and fixed to the handle.

[0051] The water injection port 3 is connected to a syringe via a Luer connector (a high-pressure syringe is recommended).

[0052] Check the linkage function between the push rod 4, the sliding pull ring 5 and the sheath tube 1, and test the bending angle of the head end 2 of the sheath tube 1.

[0053] Disinfection and inspection:

[0054] The device is disposable and can be used directly after opening without additional disinfection.

[0055] Confirm that the sheath tube 1 is not damaged and the water inlet 3 is well sealed.

[0056] 2. Operation steps

[0057] Endoscopic positioning:

[0058] The instrument is advanced to the vicinity of the target diverticulum through the colonoscope to clearly expose the diverticulum opening.

[0059] Adjust the bending angle of sheath 1:

[0060] The pushing rod 4 or the sliding pull ring 5 is operated to control the inner core 6 so that the tip end 2 of the sheath tube 1 is bent to be consistent with the direction of the diverticulum opening.

[0061] The sheath 1 is slowly advanced until its tip 2 is completely inserted into the bottom of the diverticulum.

[0062] High-pressure water flushing:

[0063] Use a syringe to draw up normal saline and connect it to the water inlet 3.

[0064] Rapid push injection uses high-pressure water flow to flush fecal stones from the bottom of the diverticulum into the intestinal cavity.

[0065] If the dirt cannot be completely removed after one flush, repeat the water injection 2-3 times.

[0066] Confirmation of fecal stone removal:

[0067] Use endoscopy to observe whether there is any fecal stone remaining in the diverticulum, and withdraw the instrument after confirming that it has been cleared.

[0068] Postoperative treatment:

[0069] Check that the intestinal mucosa is not damaged, remove the endoscope, and complete the operation.
