Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a front end cap of an endoscope and an endoscope. Background Art

[0002] Endoscopes are commonly used medical devices in modern medical diagnosis and treatment. They can directly enter the body through the natural cavity of the human body for diagnosis and treatment. When in use, the insertion part of the endoscope enters the natural cavity of the human body. The doctor can visually observe the condition of the relevant parts through the matching display, and can take photos and save them for multiple screening and comparison. The insertion part of the endoscope has an instrument channel connected to the handle of the external part. The treatment instruments (biopsy forceps, snares, hemostatic clips, electric knives, etc.) can be inserted through the instrument channel on the handle and enter the field of view of the lens for sampling, treatment, etc.

[0003] In the prior art, when performing combined surgery, after the operator finds the site of the disease, he needs to first withdraw the instrument in the endoscope cavity, then withdraw the endoscope and put on the corresponding treatment instrument, and then enter the human body again to find the treatment site for treatment. If multiple treatments are performed, it is necessary to repeatedly withdraw the treatment instrument, withdraw the endoscope, put on the combined treatment instrument, and enter the human body to find the treatment site for treatment. The convenience of surgical operation is poor, resulting in a long operation time, a high risk of surgery for patients, and a high degree of fatigue of medical staff from repeated operations. Utility Model Content

[0004] The utility model provides a front end cap of an endoscope and an endoscope, so as to solve at least one of the above problems.

[0005] According to one aspect of the utility model, a front end cap of an endoscope is provided, comprising a shell, a plurality of ligating rubber rings, a release line and a plurality of wire clamping beads; the shell is cylindrical, comprising a front end and a rear end, and the rear end is connected to the endoscope; the ligating rubber rings are sequentially sleeved on the outside of the shell; the wire clamping beads are arranged on the release line; the release line is arranged between the shell and the ligating rubber rings, and at least one wire clamping bead is arranged between adjacent ligating rubber rings; it is configured to pull the release line, so that the wire clamping bead can drive the ligating rubber ring to move toward the front end of the shell until it is separated from the shell.

[0006] The front end cap of the endoscope of the utility model can be sleeved on the front end of the endoscope. When the medical staff observes the diseased tissue through the camera of the endoscope, the front end of the front end cap can be covered with the lesion, and then the air or water pumping function of the endoscope is started. The diseased tissue will be sucked into the interior of the front end cap. At this time, the release line can be pulled outward through the instrument channel of the endoscope. Since the release line is provided with a wire clamping bead, the ligation rubber ring is driven by the wire clamping bead to move toward the front end of the front end cap. After the ligation rubber ring is separated from the front end cap, it will cover the rear part of the tissue sucked into the front end cap. The medical staff can treat the lesion through the instrument channel, and there is no need to pull out the treatment instrument one by one, withdraw the endoscope, put on the combined treatment instrument, enter the human body to find the treatment part for treatment. The operation is convenient, the operation time is short, and the surgical risk for the patient is small, which greatly avoids the repetitive work of the medical staff.

[0007] In some embodiments, release lines are provided on both sides of the housing and between the ligating rubber ring and the housing, and the release lines on both sides are connected. The ligating rubber ring is pulled on both sides to facilitate the ligating rubber ring to be separated from the front end.

[0008] In some embodiments, the distance between adjacent wire clamp beads of the present invention is greater than the distance from the ligation rubber ring to the front end of the front end cap. Thus, medical staff can choose how many ligation rubber rings to use as needed.

[0009] In some embodiments, the housing of the present invention is made of transparent material, which makes it easier for medical personnel to observe the natural cavity of the human or animal body.

[0010] In some embodiments, the housing of the utility model is a truncated cone side structure, and the front end outer diameter is smaller than the rear end outer diameter, thereby making it easier for the ligation rubber ring to detach from the front end during the traction process.

[0011] In some embodiments, the housing of the utility model is a truncated cone side structure, and the inner diameter of the front end is smaller than the inner diameter of the rear end, thereby facilitating the front end cap to be mounted on the head of the endoscope.

[0012] According to another aspect of the utility model, an endoscope including the above-mentioned front end cap is also provided, and the rear end of the front end cap is sleeved on the front end of the endoscope. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Moreover, the terms "include" and "comprise" include not only those elements, but also other elements that are not explicitly listed, or also include elements inherent to such processes, methods, articles or equipment. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the existence of other identical elements in the process, method, article or equipment that includes the elements.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Figure 1 The structure of a front end cap according to an embodiment of the utility model is schematically shown.

[0022] refer to Figure 1 As shown, the front end cap includes a shell 12 , four tying rubber rings 6 , a release line 8 and at least four wire clamping beads 5 .

[0023] The shell 12 is cylindrical and includes a front end and a rear end, and the rear end can be connected to the head 1 of the endoscope.

[0024] The ligation rubber ring 6 is sequentially sleeved on the outside of the shell 12 of the front end cap. The wire clamping bead 5 is arranged on the release line 8, and the positions of the wire clamping bead 5 and the release line 8 are relatively fixed. The release line 8 is arranged between the shell 12 and the ligation rubber ring 6, and at least one wire clamping bead 5 is arranged between adjacent ligation rubber rings 6. The diameter of the wire clamping bead 5 is larger than the diameter of the release line 8. By pulling the release line 8, the wire clamping bead 5 can drive the ligation rubber ring 6 to move toward the front end of the shell 12 until it is separated from the shell 12. In actual use, the free end of the release line 8 needs to be arranged inside the front end cap, and the release line 8 is pulled to the rear end of the instrument channel through the instrument channel of the endoscope using tools such as foreign body forceps. The release line 8 can be made of materials such as conventional medical nylon line that is not elastic. The ligation rubber ring 6 can be made of elastic silicone material, and its circumference in its natural state is much smaller than the side circumference of the front end cap.

[0025] Release lines 8 may be provided on both sides of the housing 12 and between the ligation rubber ring 6 and the housing 12, and the release lines 8 on both sides are connected. When medical personnel pull the release line 8 from the front end of the front end cap to the rear end of the endoscope, the ligation rubber ring 6 may be pulled on both sides, making it easier for the ligation rubber ring 6 to separate from the front end cap. Multiple release lines 8 may also be evenly provided on the outside of the housing 12, and these release lines 8 are connected at the front end of the front end cap. When medical personnel pull the release line 8 from the front end cap inward and backward, the wire clamping bead 5 may pull the ligation rubber ring 6 at multiple positions of the ligation rubber ring 6, making it easier for the ligation rubber ring 6 to separate from the front end cap.

[0026] The distance between adjacent wire clamp beads 5 is greater than the distance from the ligation rubber ring 6 to the front end of the front end cap, so that medical staff can pull the ligation rubber rings 6 down from the front end of the front end cap one by one, and can choose how many ligation rubber rings 6 to use as needed. Generally, 4-6 ligation collars 6 are provided, and the number can be selected according to the specific circumstances of the operation.

[0027] In the present embodiment, the housing 12 of the front end cap is made of transparent material, which is useful for medical personnel to observe the natural cavity of the human body or animal body. Of course, in other embodiments, the housing 12 of the front end cap can also be made of other opaque materials such as metal or rubber as needed.

[0028] The housing 12 of the front end cap can be designed as a structure similar to the side of a truncated cone, with the front end outer diameter slightly smaller than the rear end outer diameter. This makes it easier for the ligation rubber ring 6 to detach from the front end cap during traction. The front end outer diameter of the front end cap should not be too small, otherwise it will affect the line of sight.

[0029] The front end inner diameter of the housing 12 of the front end cap can be designed to be smaller than the rear end inner diameter, so as to facilitate the front end cap to be mounted on the head 1 of the endoscope.

[0030] Figure 2The figure schematically shows the structure of an endoscope according to an embodiment of the present invention.

[0031] refer to Figure 2 As shown, the endoscope includes a head 1, an insertion tube 2, and an operating handle 4 connected in sequence, and an opening of an instrument channel 3 is provided on the operating handle 4. A camera 11 is provided at the front end of the head 1 of the endoscope. The instrument channel 3 is connected to the interior of the front end cap, and medical personnel can extend tools such as foreign body forceps 9 into the interior of the front end cap through the instrument channel 3, and use the tools such as foreign body forceps 9 to clamp and pull the release line 8.

[0032] The front end cap can also be sleeved on the front end of the endoscope head 1. The front end cap can be disposable or can be designed as one piece with the endoscope head 1.

[0033] Figure 3 Schematically shows Figure 1 The front end cap of the endoscope is shown in use.

[0034] refer to Figure 3 As shown, the medical staff extends the front end cap, head 1 and insertion tube 2 of the endoscope with a front end cap into the natural cavity of the human body or animal body. When the medical staff observes the diseased tissue 10 through the camera 11 of the endoscope, first confirm that the free end of the release line 8 extends from the front end outside of the front end cap to the front end inside, and then cover the diseased tissue 10 with the front end of the front end cap, and then start the air or water pumping function of the endoscope. The diseased tissue 10 will be sucked into the interior of the front end cap. At this time, tools such as foreign body forceps 9 can be used to pull the release line 8 through the instrument channel 3 of the endoscope to the rear end of the instrument channel 3. Since the release line 8 is provided with a wire clamp bead 8, the ligation rubber ring 6 is driven by the wire clamp bead 8 to move toward the front end of the front end cap. After the ligation rubber ring 6 is detached from the front end cap, it will cover the rear part of the diseased tissue 10 sucked into the front end cap. After the ligation rubber ring 6 is separated from the front end cap, it will shrink to its natural state. The tissue 10 with the lesion trapped by it will become necrotic and fall off naturally after a long time, and be discharged from the natural cavity of the human body. The ligation rubber ring 6 will also fall off and be discharged from the natural cavity of the human body. In the operation that requires multiple combined instruments, medical personnel can use multiple medical instruments to treat the lesions through the instrument channel 3 respectively, without having to extract the treatment instruments, withdraw the endoscope, put on the combined treatment instruments one by one, and then enter the human body to find the treatment site for treatment. The operation is convenient, the operation time is short, and the patient's surgical risk is low. The design of the front end cap of the utility model greatly avoids the repetitive work of medical personnel.

[0035] In order to facilitate the use of an instrument to pull the release line 8 through the instrument channel 3, a coil can also be set at the free end of the release line 8, so that a hook can be used to pull the release line 8. When the ligation collar 6 on the front end cap is completely used up, the release line 8 can be pulled out of the endoscope through the instrument channel 3.

[0036] Figure 4 Schematically shows Figure 1 The usage process of the front end cap of the endoscope is shown.

[0037] refer to Figure 4 As shown, the method for using the front end cap of the endoscope includes the following steps:

[0038] S01: The medical staff inserts the front end cap, the head 1, and the insertion tube 2 of the endoscope into the natural cavity of the human body or the animal body;

[0039] S02: Observing the tissue 10 with the lesion through the camera 11 of the endoscope;

[0040] S03: Confirm that the free end of the release line 8 extends from the front end outside of the front end cap to the front end inside

[0041] S04: Covering the tissue with the lesion with the front end of the front end cap 10;

[0042] S05: activating the air or water suction function of the endoscope to suck the tissue 10 with the lesion into the interior of the front end cap;

[0043] S06: Use the foreign body forceps 9 to pull the release line 8 through the instrument channel 3 of the endoscope toward the rear end of the instrument channel 3;

[0044] S07: The ligation rubber ring 6 is driven by the wire clamping bead 8 to move toward the front end of the front end cap. After the ligation rubber ring 6 is separated from the front end cap, it will cover the rear part of the tissue 10 with the lesion that is sucked into the front end cap.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
