[0002] In the operation of urology, biopsy forceps, stone extraction nets, lasers and other instruments are often used to assist cystoscopy.

[0003] In the existing operation process of cystoscopy, the operation of the cystoscope by the attending physician can be achieved by one person, usually the right hand is used to operate the operating part, and the left hand is used to hold the cystoscope, so that the front end of the cystoscope is extended from the urethra of the patient into the body. According to the actual operation position requirement, different purposes are achieved by selecting soft and hard mirrors for operation. Another operator enters the patient's body through the instrument channel of the cystoscope by pressing and holding additional surgical instruments. In the entire operation process, at least two or more operators are required to operate the patient, which on the one hand increases the personnel cost of the operation, and on the other hand the tacit understanding of multiple people cannot completely fit, which may indirectly increase the operation risk.

[0004] Since the existing cystoscope needs to be disinfected after use to avoid secondary infection between patients. In addition, the front end of the cystoscope often adopts a snake bone structure, and the disinfection operation is difficult to effectively perform, or it is impossible to completely disinfect, resulting in a substantial increase in the use cost of the cystoscope.

[0005] In order to reduce the cost of disinfection and the waiting time of patients, a new type of cover is added to reduce the use cost of the cystoscope.

A transparent material is arranged therebetween to facilitate the subsequent insertion of the cystoscope 4A to obtain the surgical field of view.

[0088] In addition, the matched main body 3A further comprises a pair of optical fibers 411A arranged on the front end face of the outer sleeve 31. That is, when the matched main body 3A is sleeved on the cystoscope 4A and extends along the ureter of the patient, the optical fibers 411A at the front end of the outer sleeve 31 provide the operator with a light source, facilitating the operator's observation of the visual field and insertion and extension.

[0089] Unlike the previous embodiment, the cystoscope 4A comprises a cystoscope main body 44, and the cystoscope 4A comprises a functional member 41 comprising a visual unit 412 separately arranged on the front end face of the cystoscope main body 44. That is, the cystoscope 4A only provides a visual function and does not provide an illumination function. The matched main body 3A provides an illumination function.

[0090] It is worth mentioning that the instrument channel 32 leads to the surgical instrument 2, and the visual channel 33 leads to the cystoscope 4A, and the instrument channel 32 and the visual channel 33 are independent and spaced apart from each other. That is, the instrument channel 32 and the visual channel 33 are not in communication with each other. Thus, when the matched main body 3A is sleeved on the cystoscope 4, only the matched main body 3A contacts the patient's body. The cystoscope 4A does not directly contact the patient's body. Since the cystoscope 4A has a higher manufacturing cost, avoiding contact with the patient reduces the sterilization operation and further reduces the use cost of the cystoscope 4A. That is, the matched main body 3A is disposable, and after use, it can be thrown away without additional sterilization costs.

[0091] As shown in FIG. 9 is a schematic diagram of the second preferred embodiment of the present application. Unlike the above-mentioned embodiment, the single-hand fixing member 1B is changed. Specifically, the single-hand fixing member 1B includes a fitting body 11B and a fixing member 12, and has a plurality of instrument ports 13B. The fitting body 11B is connected to the counterpart body 3 through the fixing member 12, and the relative position relationship between the fitting body 11B and the counterpart body 3 is fixed through the fixing member 12. Unlike the above-mentioned embodiment, the arrangement of the instrument ports 13B is changed.

[0092] Specifically, the instrument ports 13B include a first instrument port 131B, a second instrument port 132B and a third instrument port 133B, and the first instrument port 131B, the second instrument port 132B and the third instrument port 133B are arranged vertically. That is, the first instrument port 131B, the second instrument port 132B and the third instrument port 133B are located on the same axis. The arrangement of the instrument ports 13B from the rear end to the front end of the fitting body 11B is the first instrument port 131B, the second instrument port 132B and the third instrument port 133B. That is, the arrangement of the instrument ports 13B from the rear end to the front end of the fitting body 11B is from large to small. In other words, the instrument ports 13B are arranged in a stepped manner through the fitting body 11.

[0093] Because the sizes of the instrument ports 13B are different, the surgical instruments of different radial sizes can be accommodated. Generally, when the surgical instrument 2 is implemented as a biopsy forceps 21, the biopsy forceps 21 is installed in the single-hand fixing member 1, and the holding portion 26 of the biopsy forceps 21 is clamped in the first instrument port 131. When the surgical instrument 2 is implemented as a stone extraction net 22, the stone extraction net 22 is installed in the single-hand fixing member 1, and the holding portion 26 of the stone extraction net 22 is clamped in the second instrument port 132. When the surgical instrument 2 is implemented as a laser 23, the laser 23 is installed in the single-hand fixing member 1, and the holding portion 26 of the laser 23 is clamped in the third instrument port 133. That is, the surgical instruments 2 of different implementations can be adaptively installed in the instrument ports 13 of different radial lengths.

[0094] As shown in FIG. 12 is a schematic diagram of a single-hand fixing member 1C of the third preferred embodiment of the present application. The single-hand fixing member 1C includes a fitting body 11C, a fixing member 12 and at least one instrument port 13C. One end of the fixing member 12 is connected to the fitting body 11C, and the other end is connected to the outer sleeve 31 of the counterpart body 3. The instrument port 13C is arranged on the fitting body 11C. The instrument port 13C is adapted to be allowed to pass through a surgical instrument 2.

[0095] In detail, when the surgical instrument 2 is implemented as a biopsy forceps 21, the accessory body 11C is implemented as a large-diameter ring, and a first instrument port 131 with a large diameter is allowed to pass through the biopsy forceps 21. Alternatively, the accessory body 11C can be implemented as an accessory body 11D or an accessory body 11E. When the surgical instrument 2 is implemented as a stone retrieval net 22, the accessory body 11D is implemented as a medium-diameter ring, and a second instrument port 132 with a medium diameter is allowed to pass through the stone retrieval net 22. When the surgical instrument 2 is implemented as a laser 23, the accessory body 11E is implemented as a double-layer coaxial ring with a small diameter, and a third instrument port 133 with the smallest diameter is allowed to pass through the laser 23.

[0096] The fixing member 12 includes a connecting rod 1213, a first connecting unit 1211, and a second connecting unit 1212. One end of the connecting rod 1213 is movably connected to the first connecting unit 1211 through a first movable piece 1231, and the other end is movably connected to the second connecting unit 1212 through a second movable piece 1232. The fixing piece 122 is tightly connected to an outer cover 31 of the matched body 3. The first connecting unit 1211 is integrally connected to the fixing piece 122. The second connecting unit 1212 is integrally connected to the accessory body 11C and the like. The connecting rod 1213 movably adjusts the positional relationship between the surgical instrument 2 and the outer cover 31 to adapt to the operator's control of the matched body 3 while controlling the surgical instrument 2 fixed by the one-handed fixing member 1C. The accessory body 11C is replaced to adapt to the installation of different surgical instruments 2. That is, according to different implementations of the surgical instrument 2, different accessory bodies 11C, 11D, and 11E are respectively connected to the connecting rod 1213 through the second connecting unit 1212 and the second movable piece 1232.

[0097] As shown in FIG. 13, it is a whole schematic diagram of a single-hand fixing member 1F provided by the present application. The single-hand fixing member 1F is only suitable for a laser 23. That is, the laser 23 is fixedly installed on a matched main body 3 through the single-hand fixing member 1F. Different from the above-mentioned embodiment, the single-hand fixing member 1F comprises a fitting main body 11F and a fixing member 12F and has an instrument port 13F, the fitting main body 11F is fixed on one side of the outer cover in a double-layer coaxial ring. The fixing member 12F is used for multi-angle rotation to adjust the direction of the fitting main body 11F in real time. Different from the above-mentioned embodiment, the fixing member 12F lacks a connecting rod 1213, so that the fitting main body 11F is closer to the outer cover 31, so that the laser 23 is more easily passed through the instrument port 13F to enter an instrument channel 32 communicated to the front end face of the matched main body 3.

[0098] As shown in FIG. 14, it is a whole schematic diagram of a single-hand fixing member 1G provided by the present application. The single-hand fixing member 1G is suitable for various diameters of a surgical instrument 2. That is, when the surgical instrument 2 is implemented as a biopsy forceps 21, a stone extraction net 22 and a laser 23, the surgical instrument 2 can be fixed on a matched main body 3 through the single-hand fixing member 1G. In other words, the single-hand fixing member 1G is adjustable in diameter.

[0099] Specifically, the single-hand fixing member 1G comprises a fitting main body 11G, a fixing member 12G and an instrument port 13G, the fitting main body 11G is installed on the outer cover 31 through the fixing member 12G, and the instrument port 13G is arranged on the fitting main body 11G.

[0100] It is worth mentioning that the fitting main body 11 is adjustable in radial length, the single-hand fixing member 1G comprises an adjusting member 15G arranged at the side end of the fitting main body 11G to adjustably control the radial size of the instrument port 13. The instrument port 13 is allowed to pass through a surgical instrument 2.

[0101] The fixing member 12G comprises a connecting assembly 121G, a fixing member 122 and a movable assembly 123G. The connecting assembly 121G is movably connected to the fixing member 122 through the movable assembly 123G, and the fixing member 122 is fixed to the matched main body 3. Different from the above-mentioned embodiments, the connecting assembly 121G lacks a connecting rod, so that when the accessory main body 11 is installed on the matched main body 3 through the fixing member 12, the extension passage of the instrument port 13 tends to be parallel to an instrument passage 32 of the matched main body 3. Thus, when the surgical instrument 2 is installed on the single-hand fixing member 1G, it is closer to the matched main body 3, and it is more convenient for the operator to operate with one hand.

[0102] Those skilled in the art should understand that the above description and the embodiments of the present application shown in the drawings are only examples and do not limit the present application. The purpose of the present application has been fully and effectively achieved. The function and structural principle of the present application have been shown and described in the embodiments, and the embodiments of the present application can be modified or changed in any way without departing from the principle.
