The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0033] In this embodiment, a device for placing and removing instruments through a cavity is provided, which is used to place instruments into a target position of a human body through a cavity and to remove instruments from a target position of a human body through a cavity. Among them, the cavity includes naturally existing cavities in the human body, such as the esophagus, intestines, airways, vagina, urethra, etc. It also includes channels for artificial puncture, such as fistula channels in the abdomen. The instrument is placed into the corresponding target position interval through the above-mentioned cavity, such as the bladder, stomach, large intestine, uterus, etc. The device for placing and removing instruments through a cavity includes a rod body 1, a fixing unit and an observation unit. Among them, one end of the rod body 1 is an operating part 11, which is always located outside the human body during use. The other end of the rod body 1 is a connecting part 12, which needs to be extended into the human body during use. The fixing unit includes a fixing structure and an operating structure. The fixing structure is arranged on the connecting part 12, which is used to fix or release the instrument. The operating structure is arranged on the operating part 11, which is used to control the action of the fixing structure. The observation unit includes a capture module 8 and a display module. The capture module 8 is disposed on the connection portion 12, and is used to capture the image in front of the connection portion 12. The display module is disposed on the operation portion 11, and is used to display the image captured by the capture module 8.

[0034] In order to more conveniently describe the structure and working principle of the present invention. The operating object of the following embodiments is explained by taking a bladder floatation device as an example. The bladder floatation device is in the shape of a capsule as a whole and needs to be inserted into the bladder through the urethra to perform thermal therapy in the bladder. Therefore, the fixing structure needs to be able to fix and release the bladder floatation device, and the diameter of the rod body 1 is required to meet the insertion range of the urethra. After the bladder floatation device is sent into the bladder through the urethra, it can be detached from the bladder floatation device and withdrawn from the urethra. When the bladder floatation device needs to be taken out, the placement rod can be extended into the bladder to fix the bladder floatation device, and then the bladder floatation device is taken out of the bladder through the urethra.

[0035] Embodiment 1

[0036] Please refer to Figure 1 The end of the connecting portion 12 of the rod body 1 is bent relative to the rod body 1, and the angle between the connecting portion 12 and the rod body 1 is 135 degrees, so that the connecting portion 12 can more easily pass through the second physiological curve of the male urethra, or some other physiological curves of the cavity. At the same time, a columnar protrusion 5 is provided at the end of the connecting portion 12.

[0037] The fixed structure adopts an electromagnet 2. The electromagnet 2 is set in a ring shape and is sleeved on the columnar protrusion 5. Figure 2 As shown. The bladder floatation device, which is the fixed object, is provided with a docking slot that matches the columnar protrusion 5. A magnet that can be attracted by magnetic force is also provided in the docking slot. The purpose of designing the docking slot and the columnar protrusion 5 is to play a guiding role, so that the electromagnet 2 can correspond to the magnet, thereby making it easier to limit the fixing direction of the bladder floatation device and not easy to fall off.

[0038] The operating structure includes a button switch 3 and a power supply, which are both arranged on the operating portion 11 of the rod body 1, and the electromagnet 2, the button switch 3 and the power supply form a closed loop. When the button switch 3 is turned on, the electromagnet 2 has magnetism to achieve magnetic attraction and fixation of the magnet, thereby fixing the bladder floatation device. When the button switch 3 is turned off, the electromagnet 2 loses its magnetism, so that the bladder floatation device can be naturally separated from the connecting portion 12.

[0039] In order to observe the position of the connecting portion 12 in the human body, the capture module 8 uses an optical objective lens. The display module uses an optical eyepiece 9. A corresponding optical channel is provided between the optical objective lens and the optical eyepiece 9 for transmitting light. The area where the optical objective lens collects images is located in front of the connecting portion 12. Figure 3 As shown, the capture module 8 can be directly set on the columnar protrusion 5, so as to facilitate the observation of the image at the front end of the rod body 1. This design needs to be used when the front end of the rod body 1 is not fixed with an object, and is suitable for the rod body 1 to be used alone as an endoscope. In addition, in other designs, in order not to block the field of view of the observation unit. The cross-sectional area of ​​the connecting portion 12 should be slightly larger than the cross-sectional area of ​​the fixed device. Figure 4 As shown, the cross section of the connecting portion 12 is set to be convex. The protruding part is the installation position of the capture module 8. Figure 5 As shown, the cross section of the connecting portion 12 is still set to a circular shape. At this time, the columnar protrusion 5 and the electromagnet 2 are set at the eccentric position of the end face of the connecting portion 12, and the capture module 8 is set at the remaining position. At this time, the operator can judge the current position by observing the image transmitted by the optical objective lens through the optical eyepiece 9, so as to facilitate the placement of the bladder floatation device in the correct target position. When it is necessary to recover it from the human body, the bladder floatation device in the bladder can be easily found through the observation unit, and it can be fixed by magnetic attraction. After the fixation is completed, it can be taken away from the human body through the urethra to complete the recovery.

[0040] In addition, two pipes can be provided on the rod body 1. One end of the two pipes extends to the operating part 11, and the outlet is located at one end close to the electromagnet 2. The other end of the pipes extends to the operating part 11, and a valve 4 for opening and closing the pipes is provided on the operating part 11. The two pipes are used as an inlet pipe and an outlet pipe, respectively, to form a flushing unit. When the connecting part 12 is extended into the human body, the inlet pipe is connected to an external flushing water supply device, and the flushing water is injected into the corresponding cavity or part through the inlet pipe. The refluxed flushing water is discharged to the corresponding recovery equipment through the outlet pipe, so that the rod body 1 can complete the flushing work of the corresponding cavity or part while placing objects.

[0041] Embodiment 2

[0042] The difference between this embodiment and the first embodiment is that the structure of the observation unit is different. Figure 6 , the capture module 8 can use an electronic lens, such as CCD or CMOS, and is equipped with a corresponding light source. The display module can use a display screen 10. The display screen 10 and the electronic lens are connected by a wire. The wire is arranged inside the rod body 1. The electronic lens collects the image in front of the connecting part 12, converts the image signal into an electrical signal, and the electrical signal is transmitted to the display screen 10 along the wire. Finally, the electrical signal is processed by the image processing system built into the display screen 10, and a clear image is formed on the display screen 10 for real-time playback. This method can more conveniently observe the position and state of the connecting part 12, thereby making the fixation and release of the bladder floatation device more accurate and convenient.

[0043] Embodiment 3

[0044] Compared with the first and second embodiments, the present embodiment differs in that the fixing unit is different. The fixing structure adopts a closable clamp claw 6. The clamp claw 6 is installed at the end of the connecting portion 12. Specifically, Figure 7As shown, the clamp claw 6 is set to a scissor-type, similar to a scissor structure. The clamp claw 6 includes two claws and a spring. The two claws are hinged to each other and installed at the end of the rod body 1 through a connecting piece. The function of the spring is to make the two claws tend to be in an open state. The operating structure includes an operating handpiece and a cable 7. The operating handpiece is arranged on the operating part 11 and is connected to one end of the two claws through the cable 7. The operating handpiece moves through the pulling of the cable 7 to close the clamp claw 6 and clamp the bladder floatation instrument. When releasing the bladder floatation instrument, only the operating handpiece needs to be relaxed, and the two claws are reset under the action of the spring to make the bladder floatation instrument detach from the clamp claw 6. The fixing unit can be adapted to most micro-internal instruments, and can achieve stable fixation for various types of instruments, thereby facilitating the placement and recovery of the instruments. The position of the capture module 8 in this embodiment is the same as that in the first embodiment, and it can be set at the middle position of the end face of the rod body 1. At this time, the clamp claw 6 needs to be set at an eccentric position; if the capture module 8 is set at the eccentric position of the end face of the rod body 1, the clamp claw 6 is set at the middle position. You can choose any setting according to the specific situation. The effects and functions of the two position designs are not much different, only the processing technology is different.

[0045] Embodiment 4

[0046] Compared with the first embodiment, the present embodiment is different in that the observation unit and the flushing unit are removed. Figure 8 As shown, the device for placing and removing instruments through the cavity is composed of a rod body 1 and a fixing unit. The structure of the device for placing and removing instruments through the cavity in this embodiment is simpler than that of the above-mentioned embodiment, making it lighter and easier to operate, especially for such instruments that need to pass through the cavity, which can reduce the fatigue of the operator.

[0047] Embodiment 5

[0048] Compared with the first embodiment, the present embodiment is different in that it further includes a magnet independently arranged from the rod body 1. The magnet can be fixed on the instrument to be inserted, such as being fixed on the outer shell of the instrument by gluing. The magnet can be arranged in a ring shape, matching the cylindrical protrusion 5 at the end of the connecting portion 12. The cylindrical protrusion 5 can guide the magnet to be easily mounted thereon, so that the magnet can be magnetically fixed to the electromagnet 2. The independently arranged magnet can be fixed on the outer shell of any micro-internal instrument, thereby realizing magnetic fixation of various types of instruments, facilitating the subsequent transcavitary placement and recovery.

[0049] Embodiment 6

[0050] This embodiment provides an operation method for implementing transluminal placement, which can use any of the transluminal placement devices for inserting and removing instruments in the above embodiments. The operation method for implementing transluminal placement includes the following steps:

[0051] The connecting part 12 is inserted into the human body through the cavity, and after the target position in the human body is determined according to the image collected by the observation unit, the device is released to the target position through the fixing unit;

[0052] The connecting portion 12 is extended into the human body through the cavity. After the position of the device in the human body is determined according to the image collected by the observation unit, the fixing unit fixes the device and takes it out of the human body.

[0053] Through this operation method, the instrument can be easily placed in the desired target position. At the same time, the operation method of the placement device to fix the instrument is relatively simple, and the instrument can be fixed and released with one hand, and the fixation of the instrument is reliable, which can ensure the stability of the instrument during the placement and recovery process. The placement device for inserting and removing instruments through the cavity fills the gap of no special placement and recovery tools for micro-internal instruments, and is worthy of promotion and research.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
