Abstract

The present invention provides a bladder pyeloscope, comprising a pyeloscope sheath, a pyeloscope body, a lithotomy forceps and clamp module, a lithotomy forceps and clamp passage pipe, a chippings passage pipe, an optical fiber passage pipe and an endoscopic imaging module. The end of the pyeloscope sheath is provided with a washing liquid passage opening. One ends of the lithotomy forceps and clamp passage pipe, the chippings passage pipe and the optical fiber passage pipe are respectively communicated with a pull rod inlet at the pyeloscope body, a chippings passage opening and an optical fiber inlet; the other ends are inserted into the pyeloscope sheath and are extended to the end of the pyeloscope sheath. The chippings passage opening is communicated with a chippings passage. The gap inside the pyeloscope sheath is a liquid washing passage which is communicated with the washing liquid passage opening. The lithotomy forceps and clamp module comprises a jaw and a pull rod which is put through the lithotomy forceps and clamp passage to be connected with a handle. The lithotomy forceps and clamp module is arranged outside the end of the lithotomy forceps and clamp passage pipe. One end of the endoscopic imaging module is connected with the pyeloscope body, and the other end is arranged at the end of the optical fiber passage pipe. The present invention has the functions of diagnosing, fixing stone, washing and absorbing chippings, taking the chippings, etc. and has important clinical application value.

Example Embodiment

[0022] 1 and 2, the bladder-renal pelvic lithotripsy mirror of the present invention includes a straight tubular mirror sheath 1 with open ends and a mirror body 2, and the mirror body 2 is connected to one end of the mirror sheath 1;

[0023] It is characterized in that it also includes a stone extraction clamp assembly, a stone extraction clamp channel tube 4, a lithotripsy channel tube 5, a fiber channel tube 7 and an endoscopic imaging assembly;

[0024] The end of the lens sheath 1 is provided with an irrigation fluid channel port 101 communicating with the inner cavity;

[0025] One ends of the said stone-removing clamp channel tube 4, the gravel channel tube 5 and the fiber channel tube 7 are respectively connected to the rod entrance 201, the gravel channel opening 202 and the optical fiber entrance 203 on the mirror body 2, and the other end is inserted into the mirror body. In the sheath 1 and extending to the end of the mirror sheath 1, the gravel passage opening 202 is connected to the gravel passage 204 provided with a gravel inlet 205 extending outside the lens body 2, and the gap in the mirror sheath 1 is Liquid flushing channel 6, said liquid flushing channel 6 is in communication with the flushing liquid channel opening 101 provided on the scope 1;

[0026] 1 and 3, the stone-removing jaw assembly includes a jaw 301 and a pull rod 302 connected to the jaw 301, and the other end of the pull rod 302 passes through the stone-removing jaw channel 2 and is arranged on the mirror body 2. The upper handle 9 is connected, and the clamp 301 is arranged outside the end of the end of the stone-removing clamp channel tube 4 away from the mirror body 2;

[0027] One end of the endoscopic imaging assembly is connected to the scope 2 and the other end is arranged outside the end of the fiber channel tube 7;

[0028] With reference to Figure 1, Figure 2, Figure 3, Figure 4, Figure 5 and Figure 6, the mirror body 2 is provided with a sliding groove 206, and the clamp 301 includes a frame-shaped upper pliers body 311 and an upper pliers rod 312. Frame-shaped lower pliers body 313, lower pliers rod 314 and connecting rod 315, said upper pliers body 311 and lower pliers body 313 respectively bulge outwards to form a ring, as shown in Figure 5, which is convenient for fixing stones or taking in For other foreign bodies in the body, one end of the upper pliers rod 312 is connected to one side of the upper pliers body 311, one end of the lower pliers rod 314 is connected to one side of the lower pliers body 311, and the middle of the upper pliers rod 312 and the lower pliers rod 314 are mutually connected. The other end of the upper pliers rod 312 and the lower pliers rod 314 are movably connected with the connecting rod 315 through the pin, and the other end of the connecting rod 315 is connected with the tie rod 302 through the pin, and the tie rod 302 is inserted into the stone removal clamp channel tube 4. It extends to the sliding groove 206 on the mirror body 2, and is connected with the handle 9 through the fixed pin 11. When the handle 9 moves horizontally, it can drive the pull rod 302 to move, so that the upper pliers body 311 and The lower forceps body 313 is opened or closed for fixing stones or ingesting various foreign bodies in the body.

[0029] Further, referring to Figure 1, the endoscopic imaging assembly includes an objective lens 801, an eyepiece 802, a light source 803, a light source fiber and an imaging return fiber. The objective lens 801 is fixed at the end of the fiber channel tube 7, and the eyepiece 802 and the light source 803 They are respectively arranged on the lens body 2, one end of the imaging return fiber is connected to the eyepiece 802, the other end is connected to the objective lens 801 through the fiber channel tube 7, one end of the light source fiber is connected to the light source 803, and the other end is passed through the fiber channel tube 7 and extend to the end of the fiber channel tube 7; the structure and connection relationship of the endoscopic imaging assembly are conventional technologies, and will not be repeated in the present invention;

[0030] Further, the lens body 2 and the lens sheath 1 are fixedly connected by a bite.

[0031] Further, the present invention also includes an inner core 10 that is matched with the lens sheath 1, one end extends out of the lens sheath 1 and the end is arc-shaped, as shown in Figure 7, before inserting the lens sheath 1 into the human body, first insert the inner core 10 into the lens sheath 1. To prevent the lens sheath 1 from damaging human organs, after inserting it into the human body, pull out the inner core 10 and connect it with the lens body to perform the operations of fixing the stones, crushing the stones and ingesting the gravel.

[0032] Preferably, the stone removal clamp channel tube 4 is located in the upper row, the fiber channel tube 7 is located in the middle, and the gravel channel tube 5 is located in the lower row;

[0033] The fiber channel tube 7 is located in the middle, which is convenient for visual observation, the imaging return fiber and the light source fiber can be effectively protected and are not easily damaged. The rock removal clamp channel tube 4 is located in the upper row, which is convenient for the operation of rock removal.

[0034] The invention is used as follows:

[0035] Insert the inner core 10 into the scope sheath 1, after inserting it into the human body, pull out the inner core 10, and then connect the lens body, use the endoscopic imaging component to find stones or foreign bodies, fix the stones through the stone-removing clamp component, and then use conventional means For example, pneumatic ballistic lithotripsy technology and laser lithotripsy technology, the airflow or laser is passed through the lithotripsy channel tube 5 to crack the lithotripsy, and the stones are crushed, and then the flushing liquid is sent through the flushing fluid channel port 101 for flushing.
