Description

Technical Field

[0001] The present invention relates to the technical field of endoscopes, and in particular to an electronic ureteroscope and a suspension system. Background Art

[0002] A ureteroscope is a slender instrument consisting of a light guide, a working lumen, and various working accessories for different purposes. Currently, ureteroscopes are generally divided into flexible ureteroscopes (hereinafter referred to as "flexible scopes") and rigid ureteroscopes (hereinafter referred to as "rigid scopes").

[0003] Currently, soft and hard endoscopes are used in different surgical stages. Therefore, they need to be used together during the actual operation. However, for ease of use, ureteroscopes with both soft and hard functions are also provided (mainly achieved through a soft tube body and a support rod). For example, a ureteroscope disclosed in the prior art with authorization announcement number CN103110455B can switch between soft and hard endoscopes.

[0004] Still taking the above-mentioned prior art as an example, although this ureteroscope has the advantages of both soft and hard ureters, it still has the following shortcomings:

[0005] 1. When the flexible tube body and the support rod are assembled and used, the support rod needs to be rotated a certain angle when immersed in the flexible tube body to complete the fixation. Therefore, if the support rod is disassembled when the ureteroscope is in the patient's body, there is a possibility of causing damage to the patient's organs.

[0006] 2. After use and cleaning, the ureteroscope needs to be dried. During drying, in order to ensure the drying effect, the support rod and the hose body (scope body) need to be separated and dried separately. When using it next time, it is also necessary to identify the models of the support rod and the scope body. The two must correspond before they can be used, so there is inconvenience.

[0007] 3. The current drying effect of ureteroscope is not ideal, which is mainly reflected in the working cavity of the ureteroscope, such as the instrument channel of the ureteroscope. Due to the length and diameter of the channel, it is difficult for airflow to enter, so there is a disadvantage of low drying efficiency.

[0008] In summary, necessary improvements need to be made to the above defects. Summary of the invention

[0093] The support rod 30 can be inserted into the tube body 200 from the entrance of the instrument channel 203 and supports the tube body 200, and has drainage cavities 31 penetrating at both ends;

[0094] The sealing structure 4 is composed of a connecting part and an electromagnetic part installed on the connecting part through a spring, wherein the connecting part, the spring and the electromagnetic part are coaxially arranged and form an insertion cavity 42 for the support rod 30 to pass through and communicate with the instrument channel 203;

[0095] The image transmission optical fiber and the light guide optical fiber are both arranged in the tube body 200, and the electromagnetic part has a plurality of sealing pieces 43 that move around the axis of the insertion cavity 42, and the sealing pieces 43 can be controlled by the electromagnetic part and maintained in the first mode or the second mode;

[0096] In the first mode (ref. Figure 4 ), the electromagnetic part is energized and approaches the connecting part, the sealing sheets 43 are driven to move closer to each other and form a limit block for clamping the outer wall of the support rod 30 or supporting the end of the support rod 30;

[0097] In the second mode (ref. Figure 5 ), the electromagnetic part is powered off and driven by the spring to move away from the connecting part, and the sealing sheets 43 are driven to separate from each other.

[0098] In this embodiment, the sealing structure includes:

[0099] The annular connector 40 (the connecting part of this embodiment) is detachably mounted on the entrance of the instrument channel 203, and in this embodiment, a threaded connection can be used;

[0100] The annular electromagnet 41 (the electromagnetic part of this embodiment) is spaced apart from the annular connector 40 and has an electromagnet 41a disposed therein;

[0101] A spring 40a is connected between the annular connector 40 and the annular electromagnet 41;

[0102] The movable cavity 44 is formed on the annular electromagnet 41 and has an opening 44a located on the inner wall of the annular electromagnet 41;

[0103] A recessed groove formed on the inner wall of the active cavity 44;

[0104] A nut 45 is disposed in the recessed groove;

[0105] The sealing sheet 43 is mounted on the nut 45 and can be controlled to rotate by the nut 45 and move out from the open opening 44a;

[0106] The limiting screw is composed of a limiting shaft 460 installed on the annular connector 40 and slidably connected to the annular electromagnet 41, and a screw 461 integrally formed with the limiting shaft 460 and having one end passing through the nut 45;

[0107] The limiting shaft 460 is located in the inner circle of the spring 40a, which can prevent the spring from twisting and causing the annular electromagnet to be unable to move.

[0109] refer to Figure 1-Figure 5 , the use principle of this embodiment is:

[0110] During installation, the annular connector is first inserted into the entrance of the instrument channel and connected to the mirror body through threads to complete the installation. After the installation is completed, one end of the compensation cavity is located between the annular connector and the annular electromagnet.

[0111] When switching to the hard endoscope state, one end of the support rod is inserted from the insertion cavity and enters the instrument channel to support the tube body to form a hard endoscope. After the insertion is completed, one end of the support rod contacts the annular electromagnet, and the electromagnet in the annular electromagnet is energized and generates magnetism to adsorb the support rod and notify it to move close to the annular connecting part. When moving, one end of the compensation cavity is closed and contacts the annular connecting part at the same time. When the annular electromagnet moves, the nut is driven by the screw to move, so that the sealing sheets are close to each other and clamp the support rod, thereby completing the installation.

[0112] When switching to the soft endoscope state, the electromagnet is powered off, causing the annular electromagnet to pop out, and the operator takes the support rod out of the instrument channel, and the tube body loses the support of the support rod and switches to the soft endoscope state.

[0113] This embodiment not only enables the ureteroscope to be switched between a soft endoscope and a hard endoscope through the provision of a support rod and a sealing structure, but is also extremely convenient during assembly.

[0145] In this embodiment: the air intake structure includes:

[0148] An air outlet pipe, one end of which is connected to the air outlet of the drainage pump 90, and the other end of which is extended to the driven disk 83, and a plurality of air outlet nozzles 92 are installed on the driven disk;

[0149] The air outlet nozzles 92 are distributed at equal intervals in the central circumferential direction of the driven disk 83 and are adapted to the inlet of the drainage cavity 31 .

[0150] In this embodiment, a support block 30 a having a diameter greater than the limiting opening 73 is disposed at the end of the support rod.

[0151] refer to Figure 6-Figure 9 , the principles and advantages of this embodiment are:

[0152] 1. Separation principle: After the ureteroscope is used, the electromagnet on the ureteroscope is powered off and loses its magnetism, causing one end of the support rod to pop out. The distance between the popped-out support block and the liquid inlet and outlet nozzles on the mirror body is respectively adapted to the distance between the rotating plates on the first screw seat and the second screw seat. Therefore, the mirror body can be placed on the rotating plate of the first screw seat, and the support block is placed on the rotating plate of the second screw seat. The movement of the first screw is controlled by the second motor, and the second screw is driven to move synchronously by the gear set, thereby realizing the separation of the support rod and the mirror body, that is: driven by the screw, the mirror body descends in the lower area, and the support rod rises in the upper area to complete the separation.

[0153] 2. Installation principle of the mirror body and the support rod: the user moves the curved limit rod through the support block and opens the material removal port, so that the mirror body and the support block can be placed in the limit port of the rotating plate respectively. It should be noted that when the mirror body enters the limit port, the liquid inlet nozzle and the liquid discharge nozzle are respectively located in the notch 73a (at this time, one end of the liquid inlet nozzle and the liquid discharge nozzle are against the inner wall of the notch and closed), thereby supporting the mirror body on the rotating plate, and the diameter of the support block is larger than the diameter of the limit port, so it can be stuck at the limit port. After the support block and the mirror body are placed in, close the curved limit rod to prevent them from falling off.

[0154] 3. Drying principle: When the support rod rises, the support block contacts the driven disk, and any air outlet nozzle on the driven disk enters the drainage cavity. When the drainage pump is started, the gas in the cabinet cavity enters from the air inlet nozzle on the inner wall of the lower area and is ejected from the air outlet nozzle on the driven disk. The airflow ejected from the air outlet nozzle enters the drainage cavity, and is sent into the instrument channel of the scope through the drainage cavity, and is discharged after flowing in the instrument channel, completing the drying;

[0155] Secondly, the air outlet nozzle that is not matched with the drainage cavity sprays the gas from top to bottom and dries the outer wall of the support rod and the mirror body.

[0156] 3.1 It is worth mentioning that: when drying, the electromagnet of the sealing structure can be energized to fix the support rod and close the compensation cavity, so that the airflow can enter the instrument channel from the drainage cavity, thereby mainly completing the drying of the instrument channel; when the electromagnet of the sealing structure is powered off, the sealing structure opens the compensation cavity on the mirror body. Therefore, the airflow in the drainage cavity can not only enter the instrument channel, but also enter the drainage channel and the liquid inlet channel through the compensation cavity (because the liquid inlet nozzle and the liquid discharge nozzle are closed against the inner wall of the notch, the airflow can enter the liquid inlet channel and the liquid discharge channel from the compensation cavity), and dry both.

[0157] 4. Storage principle: In this embodiment, the multiple storage cavities provided on the rotating body can store multiple ureteroscopes, and due to the rotating arrangement of the rotating body, only one cabinet door is required. When storing or taking out, the corresponding ureteroscope is moved to the cabinet door position by the rotating body rotation control, thereby completing the taking out;

[0158] 4.1 In addition, the rotating body can also be used to dry the mirror body. During the drying process, the rotating body is controlled to rotate, so that the driven gear moves around the main gear and is controlled to rotate, thereby driving the driven disk to rotate. The driven disk drives the mirror body to rotate through the support rod, thereby facilitating the airflow to shuttle through chambers such as instrument channels, and can also increase the contact frequency between the outer wall of the support rod and the lens and the top-down flowing airflow, thereby assisting drying and improving efficiency.

[0159] Embodiment 3 is different from Embodiment 2 in that a limiting body is added on the basis of Embodiment 2, as follows:

[0160] refer to Figure 10-11 In this embodiment: the lower area 52b is provided with a limiting body 95, the limiting body 95 is installed on the lower area 52b, and has a limiting cavity 96, and an opening 97 is provided at the bottom of the limiting body 95, and an air pipe is provided between the opening 97 and the air inlet nozzle 98.

[0161] In this embodiment, the diameter of the limiting cavity 96 gradually decreases from the airflow direction.

[0162] In this embodiment: a plurality of buffer rings 99 are longitudinally spaced apart in the limiting cavity 96, each buffer ring 99 is coaxially arranged in the limiting cavity 96, and an annular groove for the movement of the buffer ring 99 is provided on the inner wall of the limiting cavity 96, that is, the buffer ring 99 can rotate in the annular groove around the center of the buffer ring 99.

[0163] refer to Figure 10-11 The limiting body provided in this embodiment can allow the tube body to enter when the mirror body descends, so that when the mirror body rotates, the tube body is restricted in the limiting cavity to prevent the tube body from colliding with an object and being damaged.

[0164] To further secure the tube body, a buffer ring is provided in the limiting cavity. When the mirror body rotates and the tube body swings with the mirror body, the tube body contacts the buffer ring, and when the tube body moves, the buffer ring can be driven to move, thereby reducing the wear caused by the contact between the tube body and the limiting cavity.

[0165] What is important in this embodiment is that: the diameter of the limiting cavity gradually decreases, and the limiting cavity is connected to the air inlet nozzle through an air pipe. Therefore, when the air inlet nozzle takes in air, the limiting cavity forms an airflow flowing from top to bottom. When the mirror tube is concentrated in the limiting cavity, the drying efficiency of the mirror tube can be improved, and the cavity diameter of the limiting cavity can make the flow rate of the airflow from top to bottom faster, thereby further improving the drying efficiency.

[0166] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
