Description

Technical Field

[0001] The present invention relates to the field of medical instruments, and in particular to an endoscope sleeve and an endoscope mechanism. Background Art

[0002] Currently, an endoscope is used during examination or treatment. The endoscope is inserted into the patient's body to observe the specific condition of the patient's affected area. The endoscope can be used to see lesions that cannot be displayed by X-rays. Some endoscopes also have the function of auxiliary treatment. It is a relatively important auxiliary tool in the medical field.

[0003] Existing endoscopes are usually directly inserted into the affected part of the patient. When observing, it is usually necessary to apply pressure to the area where the affected part of the patient is located so that a greater distance is created between the endoscope and the affected part, thereby achieving the purpose of observing the affected part.

[0004] However, pressure cannot be applied to the brain, blood, etc. If pressure is applied, it will cause fatal damage to the patient. When pressure is not applied, the endoscope is close to the affected area and cannot be kept at a certain distance, so the specific situation of the affected area cannot be clearly observed. Summary of the invention

[0005] The object of the present invention is to provide an endoscope sleeve which can solve the above technical problems.

[0006] Another object of the present invention is to provide an endoscope mechanism that can solve the above-mentioned technical problems.

[0007] The embodiment of the present invention is achieved as follows:

[0008] An endoscope sleeve comprises a flexible tubular body made of a transparent material.

[0009] The flexible tubular body has a first communication pipeline and a second communication pipeline, the first communication pipeline is used to extend into the endoscope, and the second communication pipeline is used to connect to the pressure supply device;

[0010] The two ends of the flexible tubular body are respectively called a first end and a second end, and the inlet of the first connecting pipe and the inlet of the second connecting pipe are both located at the first end;

[0011] A pressurizing section is disposed on the flexible tubular body close to the second end, and an outer diameter of the pressurizing section is greater than an outer diameter of the first end.

[0012] In a preferred embodiment of the present invention, the outlet of the first communicating pipe and the outlet of the second communicating pipe are both located at the second end, and the second end is provided with a sealing member, and the sealing member is made of a transparent material.

[0013] In a preferred embodiment of the present invention, the elastic modulus of the material used for the pressurizing section is smaller than the elastic modulus of the material used for the first end.

[0014] In a preferred embodiment of the present invention, a third connecting pipeline is further included, wherein the third connecting pipeline is used to connect to the aspirator, and the inner diameters of the second connecting pipeline and the third connecting pipeline are both smaller than the inner diameter of the first connecting pipeline.

[0015] In a preferred embodiment of the present invention, the first end is provided with:

[0016] a first connecting joint connected to the first connecting pipeline;

[0017] a second connecting joint communicating with the second connecting pipeline; and

[0018] A third communication joint communicated with the third communication pipeline.

[0019] In a preferred embodiment of the present invention, the hardness of the first connecting joint, the second connecting joint and the third connecting joint are all greater than the hardness of the flexible tubular body.

[0020] In a preferred embodiment of the present invention, reinforcing ribs are provided between the first connecting joint and the second connecting joint, and between the first connecting joint and the third connecting joint.

[0021] In a preferred embodiment of the present invention, the inner cavity of the first connecting joint is a truncated cone-shaped chamber, and the diameter of the inner cavity of the first connecting joint gradually increases from one end connected with the first connecting pipeline to the other end.

[0022] An endoscope mechanism comprises an endoscope, a pressure supply device and the endoscope cover described in the above technical solution, wherein the endoscope is located in a first connecting pipeline of the endoscope cover, and the pressure supply device is used to inject liquid or gas into a second connecting pipeline of the endoscope cover.

[0023] In a preferred embodiment of the present invention, it further comprises an aspirator, and the aspirator is connected to the third connecting pipeline.

[0024] The beneficial effect of the embodiment of the present invention is that during use, the endoscope extends into the second end of the flexible tubular body or a position close to the second end through the first connecting pipe. The second connecting pipe is connected to a pressure supply device, and the pressure supply device pressurizes the second connecting pipe. The second connecting pipe can be pressurized by passing gas or liquid, so that the flexible tubular body expands. Since the outer diameter of the pressurized section itself is larger than the outer diameter of the first end of the flexible tubular body, the pressurized section plays a supporting role, and the pressurized section is used to expand the area, so that the distance between the endoscope in the first connecting pipe in the flexible tubular body and the affected area is increased, thereby facilitating the use of the endoscope to observe the specific conditions of the affected area.

[0025] In summary, by using the above-mentioned endoscope sleeve, the distance between the endoscope and the affected area is increased by expanding a part of the endoscope sleeve itself. The endoscope sleeve is suitable for multiple areas of the human body, including blood vessels and brain areas, has a wide range of applications, and is harmless to the human body.

[0044] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] First embodiment

[0046] Please refer to Figure 1 - Figure 5 The present embodiment provides an endoscope sleeve, which includes a flexible tubular body 10 made of a transparent material. The flexible tubular body 10 has a first connecting line 11 and a second connecting line 12. The first connecting line 11 is used to extend into the endoscope, and the second connecting line 12 is used to connect to a pressure supply device.

[0047] For ease of description, the two ends of the flexible tubular body 10 are respectively referred to as the first end and the second end, and the inlet of the first connecting pipe 11 and the inlet of the second connecting pipe 12 are both located at the first end.

[0048] A pressurizing section 20 is disposed on the flexible tubular body 10 near the second end. In a preferred embodiment of the present invention, the outer diameter of the pressurizing section 20 is greater than the outer diameter of the first end.

[0049] like Figure 2 As shown, the pressurized section 20 is a part of the flexible tubular body 10. For ease of description, the area from the second end to the pressurized section 20 is called the first section, and the area from the first end to the pressurized section 20 is called the tail section. The first section, the pressurized section 20 and the tail section are an integrated structure and are integrally formed during the manufacturing process.

[0050] In a preferred embodiment, the outer diameter of the transition section between the pressurizing section 20 and the first section gradually decreases, and the outer diameter of the transition section between the pressurizing section 20 and the tail section gradually decreases. Figure 2 In the direction shown, the left end of the pressurized section 20 is the tail section, and the right end is the head section. The pressurized section 20, the head section and the tail section are all straight pipe sections. The outer diameters of the head section and the tail section are equal. The outer diameter of the pressurized section 20 is greater than the outer diameter of the head section, and the outer diameter of the pressurized section 20 is greater than the outer diameter of the tail section. The transition section between the pressurized section 20 and the head section is a variable diameter section, and its outer diameter gradually decreases from left to right; the transition section between the pressurized section 20 and the tail section is a variable diameter section, and its outer diameter gradually decreases from right to left.

[0051] In actual applications, the endoscope extends through the first end of the first connecting pipe 11 and eventually reaches the second end or a position close to the second end. Specifically, the endoscope is located in the pressurizing section 20 or next to the pressurizing section 20 (it can be located at a position close to the pressurizing section 20 in the first section or at a position close to the pressurizing section 20 in the last section).

[0052] The elastic modulus of the material used in the pressurized section 20 is smaller than the elastic modulus of the material used in the first end. The elastic modulus refers to the stress required for a material to produce a unit elastic deformation under the action of an external force. The larger the elastic modulus, the greater the pressure for a material to undergo a certain elastic deformation, that is, the greater the material stiffness, that is, the smaller the elastic deformation under a certain stress. In other words, when the pressure on the pressurized section 20 is the same as that on other areas of the flexible tubular body 10, the deformation of the pressurized section 20 is greater than the deformation of other areas on the flexible tubular body 10.

[0053] With such arrangement, when liquid or gas is filled into the second connecting pipe 12, the expansion degree of the pressurizing section 20 is greater, so that the pressurizing section 20 and the area near the pressurizing section 20 are expanded to a larger size, thereby increasing the distance between the endoscope located in the pressurizing section 20 or next to the pressurizing section 20 and the affected part, so that the affected part can be observed more clearly using the endoscope.

[0054] The second connecting pipe 12 may also be connected to an optical fiber to provide lighting for the endoscope.

[0055] Furthermore, the flexible tubular body 10 also includes a third connecting pipe 13. In a specific embodiment, the first end of the flexible tubular body 10 is open and the second end is sealed. During use, the first connecting pipe 11 is used to insert an endoscope, the second connecting pipe 12 is used for pressurization, and the third connecting pipe 13 is used to pass the optical fiber.

[0056] In another specific embodiment of the flexible tubular body 10, the first end and the second end of the flexible tubular body 10 are both open, that is, the inlet of the first connecting line 11, the inlet of the second connecting line 12 and the outlet of the third connecting line 13 are located at the first end; the outlet of the first connecting line 11, the outlet of the second connecting line 12 and the inlet of the third connecting line 13 are located at the second end. During the use of this flexible tubular body 10, the first connecting line 11 is used to insert an endoscope, the second connecting line 12 is used to pass a flushing liquid (such as water or saline solution) into the affected area, and the third connecting line 13 is used to connect to an aspirator, the inlet of the third connecting line 13 is located at the second end, the outlet of the third connecting line 13 is located at the first end, and the first end is connected to the aspirator, and the substance located at the inlet of the third connecting line 13 is sucked out by the aspirator. The aspirator can be a negative pressure adsorption device.

[0057] like Figure 4 and Figure 5 As shown, the flexible tubular body 10 has an inner cavity extending in the length direction, and a partition layer is arranged in the inner cavity. The partition layer divides the inner cavity of the flexible tubular body 10 into three parts, namely a first connecting pipeline 11, a second connecting pipeline 12 and a third connecting pipeline 13.

[0058] The inner diameter of the second communication pipeline 12 is smaller than that of the first communication pipeline 11, and the inner diameter of the third communication pipeline 13 is smaller than that of the first communication pipeline 11. In other words, the cross-sectional area of ​​the inner cavity of the pipeline of the second communication pipeline 12 is smaller than that of the inner cavity of the pipeline of the first communication pipeline 11, and the cross-sectional area of ​​the inner cavity of the pipeline of the third communication pipeline 13 is smaller than that of the inner cavity of the pipeline of the first communication pipeline 11. With such a configuration, while ensuring that the first communication pipeline 11 can smoothly pass through the endoscope, the second communication pipeline 12 can complete the pressurization or water injection, and the third pipeline can complete the suction operation, the inner cavity of the flexible tubular body 10 is optimally utilized, so that the outer diameter of the flexible tubular body 10 is minimized, so that it can smoothly enter the patient's body and relieve the patient's pain.

[0059] In a specific embodiment, in the initial state, a sealing member is provided at the second end of the flexible tubular body 10, and the sealing member is made of a transparent material. The sealing member at least blocks the outlet of the second connecting pipe 12, or the sealing member blocks the opening of the second end of the flexible tubular body 10, that is, blocks the outlet of the first connecting pipe 11, the outlet of the second connecting pipe 12, and the inlet of the third connecting pipe 13. At this time, the second connecting pipe 12 can be pressurized.

[0060] When there is no need to prop up the affected area but flushing liquid needs to be injected into the affected area, the sealing member can be removed (for example, by cutting the sealing member off with scissors, or cutting off the second end portion of the flexible tubular body 10) to expose the outlet of the first connecting pipe 11, the outlet of the second connecting pipe 12 and the inlet of the third connecting pipe 13, so that flushing liquid can be injected through the second connecting pipe 12 and impurities can be sucked out through the third connecting pipe 13.

[0061] like Figure 1 - Figure 4 As shown, in order to facilitate the connection of the flexible tubular body 10 with the suction device and the pressure supply device, in a preferred embodiment, the first end of the flexible tubular body 10 is provided with a first connecting joint 31, a second connecting joint 32 and a third connecting joint 33. Specifically, the first connecting joint 31 has a first inner cavity 41, and the first inner cavity 41 is connected to the first connecting pipe 11; the second connecting joint 32 has a second inner cavity 42, and the second inner cavity 42 is connected to the second connecting pipe 12; the third connecting joint 33 has a third inner cavity 43, and the third inner cavity 43 is connected to the third connecting pipe 13.

[0062] Furthermore, the hardness of the first connecting joint 31, the second connecting joint 32 and the third connecting joint 33 is greater than the hardness of the flexible tubular body. Due to the high hardness of the connecting joint, the connection stability with other devices (such as aspirators, pressure supply devices, etc.) is strong.

[0063] Specifically, the first connecting joint 31, the second connecting joint 32 and the third connecting joint 33 are an integral structure with the flexible tubular body.

[0064] In a specific embodiment, the first connecting joint 31, the second connecting joint 32 and the third connecting joint 33 and the flexible tubular body are all made of silicone material, but the first connecting joint 31, the second connecting joint 32 and the third connecting joint 33 use silicone with relatively high hardness, and the flexible tubular body uses silicone with relatively low hardness.

[0065] like Figure 1 - Figure 4 As shown, reinforcing ribs 50 are provided between the first connecting joint 31 and the second connecting joint 32, and between the first connecting joint 31 and the third connecting joint 33. The reinforcing ribs 50 ensure that there is always a certain angle between the first connecting joint 31 and the second connecting joint 32, and between the first connecting joint 31 and the third connecting joint 33, so as to facilitate operation.

[0066] In a preferred embodiment of the present invention, the inner cavity of the first connecting joint 31 is a truncated cone-shaped chamber, and the diameter of the inner cavity of the first connecting joint 31 gradually increases from one end connected to the first connecting pipe 11 to the other end. In this way, the opening of the first inner cavity 41 of the first connecting joint 31 has a larger diameter and a larger cross-sectional size, which is convenient for inserting an endoscope. The first inner cavity 41 plays a guiding role for the endoscope, so that the endoscope can smoothly enter the first connecting pipe 11.

[0067] Second embodiment

[0068] This embodiment provides an endoscope mechanism, which includes the endoscope cover provided by the first embodiment, and also includes an endoscope and a pressure supply device. The endoscope is located in the first connecting pipe of the endoscope cover, and the pressure supply device is used to inject liquid or gas into the second connecting pipe of the endoscope cover.

[0069] When the endoscope sleeve has a third connecting pipeline, the endoscope mechanism further includes an aspirator connected to the third connecting pipeline and used for sucking out substances at the inlet of the third connecting pipeline.

[0070] Furthermore, the endoscope mechanism may also include an optical fiber, which may extend from the second connecting line or the third connecting line to provide lighting for the endoscope.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
