Description

Technical Field

[0001] The invention belongs to the medical field, and in particular relates to a disposable electronic ureteronephroscope. Background Art

[0002] With the development of medical technology, endoscopes are increasingly used in the diagnosis and treatment of urinary system diseases. As one of the important tools, ureterorenoscope plays an irreplaceable role in treating upper urinary tract stones and other diseases. However, traditional disposable or reusable ureterorenoscopes have certain limitations and challenges in actual operation, especially in the location and removal of stones inside the human body.

[0003] Currently, most ureterorenoscopes on the market require the use of an additional sheath to effectively absorb stones in the body. This design requires the doctor to stabilize the sheath and the nephroscope at the same time during the operation, which increases the complexity and difficulty of the operation. Specifically, on the one hand, the sheath must be fixed in position to provide a stable channel, and on the other hand, the nephroscope must be flexibly manipulated to accurately locate the stones and implement effective treatment measures. Such dual operations not only increase the workload of doctors, but may also affect the accuracy and safety of the operation.

[0004] Therefore, there is an urgent need to develop an integrated negative pressure suction mechanism, a disposable electronic ureteronephroscope that can directly extract kidney stones through the negative pressure suction structure on the nephroscope. Summary of the invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides an integrated negative pressure suction mechanism, which is a disposable electronic ureteronephroscope that can directly extract kidney stones through the negative pressure suction structure on the nephroscope.

[0006] The technical solution is: a disposable electronic ureteronephroscope, including a nephroscope body and a stone extraction mechanism. A hand-held sleeve, a docking plug, a bending tube and an insertion tube are installed in sequence from right to left to form the outer shell of the nephroscope body. The stone extraction mechanism includes a docking joint, a connecting tube and a conical disk. The upper surface of the hand-held sleeve is provided with a docking joint in a snap-fit manner. The bottom end of the docking joint is connected to a connecting tube. The end of the connecting tube is divided into two and inserted into the insertion tube and is flush with the left end of the insertion tube. Conical disks are evenly spaced in the bifurcation of the connecting tube, and the conical disks are elastic.

[0007] Furthermore, the conical disk protrudes to the right, and bristles are arranged on the inner wall of the conical disk.

[0008] Further, it also includes a plug and a protective sleeve. The renal endoscope body further includes a wire winding wheel, a traction wire, and a camera. A wire winding wheel is rotatably arranged at the right part inside the hand-held sleeve. The rotating part of the wire winding wheel extends to the outside of the hand-held sleeve. A traction wire is wound around the wire winding wheel. The traction wire sequentially passes through the hand-held sleeve, the docking plug, the bending tube, and the insertion tube from right to left. The end of the traction wire is connected to a camera, and the camera is located at the outlet end of the insertion tube.

[0009] Further, it also includes a stabilizing mechanism. A stabilizing mechanism is arranged inside the renal endoscope body. The stabilizing mechanism includes an air storage sleeve, an air tube, a columnar airbag, a piston rod, a pull plate, and a spring. The air storage sleeve is slidably arranged inside the hand-held sleeve along its axis. The outlet at the left side of the air storage sleeve is connected to an air tube. The outlet of the air tube is connected to a columnar airbag. The columnar airbag is sleeved outside the insertion tube. A piston rod is slidably arranged inside the air storage sleeve. The right end of the piston rod is connected to a pull plate, and a spring is connected between the pull plate and the air storage sleeve.

[0010] Further, the stabilizing mechanism also includes a locking tooth and a clamping plate. A locking tooth is arranged at the rear side of the pull plate, and a clamping plate is arranged at the rear side of the air storage sleeve. The locking tooth is clamped inside the clamping plate.

[0011] Further, it also includes a plug. A plug is arranged at the right part of the insertion tube, and the left side surface of the plug is a conical surface.

[0012] Further, it also includes a protective sleeve. A protective sleeve is sleeved on the left part of the insertion tube.

[0013] Further, it also includes a storage bladder and a communication tube. A storage bladder is arranged at the left part inside the insertion tube. The storage bladder is annular, and a communication tube is communicatedly arranged on the outer surface of the storage bladder.

[0014] Compared with the prior art, the present invention has the following advantages: When the insertion tube enters the human body in the present invention, due to the change in pressure, the coupling agent in the storage bladder flows out through the communication tube and is on the surface of the insertion tube, playing a lubricating role for the insertion tube to reduce the friction force during the insertion of the insertion tube and relieve the pain of the patient; the gas in the air storage sleeve enters the columnar airbag through the air tube, and the columnar airbag expands sequentially from right to left. The expanded columnar airbag fits with the human body, so that the position of the insertion tube is fixed. When the medical staff observes the situation, if the hand accidentally changes the position of the hand-held sleeve, the position of the insertion tube will not easily change, which is convenient for the medical staff to use; during the observation process by the medical staff, the stone extraction mechanism can also remove the stones, reducing the burden on the medical staff and improving the accuracy and safety of the operation.

[0028] The principle and structure of the present invention will be described in detail below with reference to the drawings and embodiments.

[0029] Embodiment: A disposable electronic ureterorenoscope, such as Figures 1 - 3 、 Figure 6 and Figure 7As shown in the figure, it includes a nephroscope body 1 and a stone extraction mechanism 3. The nephroscope body 1 includes a hand-held sleeve 101, a docking plug 102, a bending tube 103, an insertion tube 104, a wire reel 105, a traction wire 106, and a camera 107. A docking plug 102 is detachably connected to the left exit of the hand-held sleeve 101. The left end of the docking plug 102 is connected to a bending tube 103, and the other end of the bending tube 103 is connected to an insertion tube 104. A wire reel 105 is rotatably arranged in the right part of the hand-held sleeve 101, and the rotating part of the wire reel 105 extends to the outside of the hand-held sleeve 101. The wire reel 105 can be rotated on the outside of the hand-held sleeve 101. A traction wire 106 is wound around the wire reel 105. The traction wire 106 passes through the hand-held sleeve 101, the docking plug 102, the bending tube 103, and the insertion tube 104 from right to left in sequence. The end of the traction wire 106 is connected to a camera 107, and the camera 107 is located at the exit end of the insertion tube 104. Blocks for guiding are arranged at the docking positions of the traction wire 106 passing through the hand-held sleeve 101, the docking plug 102, the bending tube 103, and the insertion tube 104 to assist the traction wire 106 in turning. The stone extraction mechanism 3 includes a docking head 301, a connecting tube 302, a conical disk 303, and bristles 304. A docking head 301 is snap-fitted on the upper surface of the hand-held sleeve 101. The bottom end of the docking head 301 is connected to a connecting tube 302. The end of the connecting tube 302 is divided into two parts and inserted into the insertion tube 104, flush with the left end of the insertion tube 104. Conical disks 303 are evenly spaced in the bifurcated part of the connecting tube 302. The conical disks 303 protrude to the right, and bristles 304 are arranged on the inner wall of the conical disks 303. The conical disks 303 are elastic.

[0030] As Figure 4 and Figure 5As shown in the figure, it further includes a stabilizing mechanism 2. A stabilizing mechanism 2 is arranged inside the renal endoscope body 1. The stabilizing mechanism 2 includes a gas storage sleeve 201, a trachea 202, a columnar airbag 203, a piston rod 204, a pull plate 205, a spring 206, a locking tooth 207 and a locking plate 208. The gas storage sleeve 201 is slidably arranged inside the hand-held sleeve 101 along its axis. The gas storage sleeve 201 stores gas. A trachea 202 is connected to the outlet on the left side of the gas storage sleeve 201. The outlet of the trachea 202 is connected to the columnar airbag 203. Both ends of the trachea 202 are communicated with the columnar airbag 203 and the gas storage sleeve 201 respectively. The columnar airbag 203 is sleeved outside the insertion tube 104. A piston rod 204 is slidably arranged inside the gas storage sleeve 201. The right end of the piston rod 204 is connected to the pull plate 205. One side of the pull plate 205 passes through the hand-held sleeve 101 for medical staff to pull the piston rod 204. A spring 206 is connected between the pull plate 205 and the gas storage sleeve 201. By pushing or pulling the piston rod 204, the gas in the gas storage sleeve 201 can be pushed into the columnar airbag 203 or the gas in the columnar airbag 203 can be drawn out. A locking tooth 207 is arranged at the rear side of the pull plate 205. A locking plate 208 is arranged at the rear side of the gas storage sleeve 201. A row of triangular card slots are formed on the locking plate 208. The locking tooth 207 can be engaged into the locking plate 208.

[0031] As Figure 1 shown in the figure, it further includes a plug 4 and a protective sleeve 5. A protective sleeve 5 is sleeved on the left part of the insertion tube 104. Before the device is used, the protective sleeve 5 protects the end of the insertion tube 104. A plug 4 is arranged on the right part of the insertion tube 104. The left side surface of the plug 4 is a conical surface. The position of the plug 4 can be adjusted. After the insertion tube 104 enters the human body and is fixed, the plug 4 can be blocked at the entrance of the human body to prevent the entrance from being exposed outside and being infected.

[0032] As Figure 8 shown in the figure, it further includes a storage bladder 6 and a connecting tube 7. A storage bladder 6 is arranged inside the left part of the insertion tube 104. The storage bladder 6 is annular. A connecting tube 7 is communicated with the outer surface of the storage bladder 6. The end of the connecting tube 7 and the outer surface of the connecting tube 7 are on the same cylindrical plane. The storage bladder 6 is filled with coupling agent.

[0033] When the disposable electronic ureteroscope needs to be used for examination, the endoscope body 1 is docked with a computer, and the docking head 301 is docked with a negative pressure machine. Then, hold the hand-held sleeve 101 of the endoscope body 1 with the hand, and insert the left end of the insertion tube 104 into the human body for observation through the camera 107. When the insertion tube 104 enters the human body, due to the change in pressure, the coupling agent in the storage bladder 6 flows out through the communication tube 7 onto the surface of the insertion tube 104, playing a lubricating role for the insertion tube 104 to reduce the friction when the insertion tube 104 is inserted and relieve the pain of the patient. When the position of the camera 107 needs to be adjusted, rotate the wire winding wheel 105 to drive the traction wire 106 to scale, so that the bending tube 103 bends to drive the insertion tube 104 to adjust its position, thereby changing the observation position. After determining the observation position, press the piston rod 204 downward through the pull plate 205, and the spring 206 is compressed, so that the gas in the air storage sleeve 201 enters the columnar airbag 203 through the air tube 202. The columnar airbags 203 expand successively from right to left, and the expanded columnar airbags 203 fit with the human body, so that the position of the insertion tube 104 is fixed. After the position of the insertion tube 104 is fixed, engage the locking teeth 207 in the corresponding triangular grooves of the locking plate 208 to fix the position of the piston rod 204. In this way, when the medical staff observes the situation, if the hand accidentally changes the position of the hand-held sleeve 101, the position of the insertion tube 104 will not easily change, which is convenient for the medical staff to use. When it is necessary to remove the stone after finding its position, control the negative pressure machine to start working, and the stone is sucked out through the connecting tube 302. After the stone enters the connecting tube 302, even if the pressure changes due to moving the insertion tube 104, due to the blocking effect of the conical disc 303 and the bristles 304, the stone will not fall out of the connecting tube 302. At the same time, because the conical surface of the conical disc 303 faces to the right, it will not obstruct the stone when sucking the stone. After the disposable electronic ureteroscope is used up, first separate the locking teeth 207 from the locking plate 208, and the spring 206 resets to drive the pull plate 205 and the piston rod 204 to move to the right and reset. The gas in the columnar airbag 203 returns to the air storage sleeve 201 through the air tube 202, and the volume of the columnar airbag 203 becomes smaller and no longer fits with the human body. Then, the disposable electronic ureteroscope can be taken out of the human body, and then the disposable electronic ureteroscope is disconnected from the computer and the negative pressure machine for disposal.

[0034] The above embodiments are only preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
