Description

Technical Field

[0001] The invention relates to the technical field of cystoscopes, and in particular to a cystoscope with a positioning function. Background Art

[0002] A cystoscope is a type of endoscope, similar in shape to a urethral probe. It consists of a set of four parts: an electron microscope sheath, an inspection endoscope, a disposal and ureteral catheter endoscope, and a core, and is also equipped with accessories such as an electrocauterizer, a scissors, and biopsy forceps.

[0003] The prior art discloses (publication number: CN113229775B) a cystoscope catheter for urology and a method of using the same, comprising a cystoscope body and a catheter body, wherein a sealing shell is arranged on the left side of the cystoscope body, and the right side of the catheter body penetrates into the inner cavity of the sealing shell through a connecting block, and the catheter body is fixed by arranging the sealing shell, a positioning groove, a fixing seat, a cavity, a buffer spring, a buffer plate, a compression spring, a clamping block, a fixing groove, a fixing tube, a through hole, a slide groove and a slide block to cooperate with each other, thereby solving the problem that it is inconvenient to replace the catheter body in the prior art.

[0004] Since the angle of the cystoscope needs to be adjusted during use to meet different observation needs, the existing technology fixes the catheter body through a block and a pair of through holes, resulting in low freedom and flexibility of the catheter body when adjusting the angle, which can easily cause the catheter body to bend at the connection with the cystoscope body, affecting the transportation of the cystoscope by medical staff and the clarity of observation. Therefore, we propose a cystoscope with a positioning function to solve the above problem. Summary of the invention

[0005] The present invention is intended to provide a cystoscope with a positioning function to solve the problem of bending of the catheter body at the connection point of the cystoscope body.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cystoscope with a positioning function, comprising a cystoscope body and a catheter body, a positioning assembly is provided at the output end of the cystoscope body, a limit block is provided at one end of the catheter body, a clamping ring is provided on the outer wall of the limit block, the positioning assembly comprises a turntable, a fixed tube and a plurality of connecting blocks and a positioning block, the fixed tube is provided at the output end of the cystoscope body, the turntable is provided with the output end of the cystoscope body when rotating, a mounting groove is provided in an annular manner on the inner wall of the turntable, each connecting block is evenly provided in the mounting groove, each positioning block is evenly provided at one end of the fixed tube away from the cystoscope body, and the connecting block is connected to the end opposite to the positioning block, the positioning block can abut against the clamping ring on the outer wall of the limit block, and a tension spring is provided between each connecting block and the outer wall of the fixed tube.

[0007] The beneficial effects of this program are:

[0008] Through the mutual cooperation among the turntable, the fixed tube, the connecting block and the positioning block, the medical staff only needs to rotate the turntable to move the positioning block into the turntable, and then place the limiting block of the catheter body on the inner wall of the turntable. The medical staff then loosens the turntable, and the positioning block moves to the clamping ring on the outer wall of the limiting block under the action of the tension spring, thereby fixing the catheter body to the front end of the cystoscope body. In addition, because a tension spring is provided between the positioning block and the fixed tube, the catheter body can be moved slightly at the output end of the cystoscope body, thereby avoiding bending of the catheter body at the connection with the cystoscope when the angle of the catheter body is adjusted, which affects the clarity of the medical staff's transportation and observation of the cystoscope.

[0009] Preferably, as an improvement, it further includes a limiting component, which includes a mounting ring, a reset spring and a plurality of limiting blocks, a plurality of slots are provided at one end of the limiting block close to the mounting ring, a plurality of through slots are provided on the outer wall of the fixed tube, the mounting ring is arranged on the outer wall of the fixed tube, the reset spring is arranged between the mounting ring and the output end of the cystoscope body, a plurality of limiting blocks are arranged on the inner wall of the mounting ring, and the limiting blocks pass through the through slots into the fixed tube, and each limiting block can abut against the corresponding slot.

[0010] The beneficial effects are: the mounting ring is arranged on the outer wall of the fixed tube, and the limiting block can pass through the through groove and extend to the inside of the fixed tube, so that the limiting block can abut against the card groove, thereby preventing the catheter body from rotating when the angle is adjusted, thereby avoiding friction between the catheter body and the inner wall of the urethra, causing harm to the patient.

[0011] Preferably, as an improvement, the width of the clamping ring is greater than the thickness of the positioning block, so that the limiting block can float axially in the fixed tube.

[0012] The beneficial effect is that the limit block can float axially in the fixed tube, further avoiding bending of the catheter body when the angle is adjusted. When the angle of the catheter body is adjusted, the limit block moves axially to avoid bending of the catheter body.

[0013] Preferably, as an improvement, a plurality of protrusions are provided at one end of the turntable close to the mounting ring, and a plurality of grooves are provided at one end of the mounting ring close to the turntable, and the protrusions can abut against the grooves.

[0014] The beneficial effect is that the mounting ring is abutted against the mounting disc by the reset spring, so that the protrusion is matched with the groove, thereby preventing the turntable from rotating during the use of the cystoscope body and increasing the stability of the positioning assembly. At the same time, if the medical staff fails to match the card slot of the limit block with the limit block, the clamping ring on the outer wall of the limit block and the positioning block are forcibly connected by squeezing the reset spring. At this time, since the reset spring is in a compressed state, the positioning block is abutted against the inner wall of the clamping ring, thereby hindering the movement of the positioning block, causing the limit block to be unable to float normally, and then causing the catheter body to bend when the angle is adjusted. To avoid this situation, the medical staff can rotate the turntable after docking the limit block with the positioning block. If the rotation resistance of the turntable is large, it means that the limit block and the slot are in a normal docking state. At this time, the connection between the limit block and the slot can prevent the catheter body from rotating. At the same time, the positioning block does not abut against the inner wall of the clamping ring, so that the limit block can float and avoid bending of the catheter body. If there is no resistance when rotating the turntable, it means that the installation ring does not abut against the turntable, thereby prompting the medical staff that the slot of the limit block is not docked with the limit block, and then warning the medical staff to reinstall the limit block.

[0015] Preferably, as an improvement, the connecting block is configured to be arc-shaped, and the end of the positioning block abutting against the clamping ring is configured to be arc-shaped.

[0016] Preferably, as an improvement, a plurality of support grooves are provided at one end of the fixing platform close to the positioning block, and the connecting block can be moved to the upper end of the corresponding support groove, and a tension spring is provided between the connecting block and the support groove.

[0017] The beneficial effect is that the support groove is used to shorten the moving stroke of the positioning block, thereby making the positioning assembly structure more compact.

[0018] Preferably, the outer wall of the turntable is provided with anti-slip teeth. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, the connecting blocks 7 and the positioning blocks 8 are both set to 5, such as Figure 3 The fixed tube 6 is fixedly mounted on the inner wall of the output end of the cystoscope body 1, and the turntable 5 is rotatably mounted on the output end of the cystoscope body 1 through the cooperation of the slide groove and the slider. The outer wall of the turntable 5 is fixedly mounted with anti-slip teeth, and the inner wall of the turntable 5 is annularly provided with a mounting groove 9, as shown in FIG. Figure 4 and Figure 5 One end of each connecting block 7 shown is rotatably mounted on the inner wall of the mounting groove 9, the connecting block 7 is arranged in an arc shape, and can be completely rotated into the mounting groove 9, one end of each positioning block 8 is rotatably mounted on the upper end of the fixed tube 6, and the connecting block 7 is rotatably connected to the end adjacent to the positioning block 8, and the end of the positioning block 8 abutting against the snap ring 4 is arranged in an arc shape, and can abut against the snap ring 4 on the outer wall of the limit block 3, as shown in FIG. Figure 6 Five support grooves 18 are provided on the upper end of the fixed platform shown, and the connecting block 7 can be moved to the upper end of the corresponding support groove 18. A tension spring 10 is fixedly installed between each connecting block 7 and the support groove 18. The tension spring 10 is used to pull the connecting block 7 close to the fixed tube 6. The width of the clamping ring 4 is greater than the thickness of the positioning block 8, so that the limit block 3 can float axially in the fixed tube 6.

[0029] The limiting assembly also includes a mounting ring 11, a return spring 12 and a plurality of limiting blocks 13, such as Figure 2 The limit block 3 shown in the figure has a plurality of slots 14 at one end. Figure 3The outer wall of the fixed tube 6 shown is provided with a plurality of through grooves 15, the mounting ring 11 is sleeved on the outer wall of the fixed tube 6, the return spring 12 is fixedly installed between the mounting ring 11 and the output end of the cystoscope body 1, and a plurality of limiting blocks 13 are fixedly installed on the inner wall of the mounting ring 11, and the limiting blocks 13 pass through the through grooves 15 to the fixed tube 6, and each limiting block 13 can abut against the corresponding card slot 14.

[0030] A plurality of protrusions 16 are fixedly mounted on one end of the turntable 5 close to the mounting ring 11 , and a plurality of grooves 17 are formed on one end of the mounting ring 11 close to the turntable 5 . The protrusions 16 can abut against the grooves 17 .

[0031] The specific implementation process is as follows:

[0032] When in use, the medical staff rotates the turntable 5 so that the connecting block 7 rotates with the turntable 5, thereby pulling the positioning block 8 rotatably connected to the connecting block 7 to move into the installation groove 9, so that the positioning block 8 is received in the installation groove 9. At this time, the medical staff installs the limiting block 3 of the catheter body 2 into the turntable 5 and the fixed tube 6, and makes the card slot 14 at the lower end of the limiting block 3 abut against the limiting block 13 to prevent the catheter body 2 from rotating, thereby avoiding the catheter body 2 from rubbing against the inner wall of the urethra and causing harm to the patient. Then the medical staff loosens the turntable 5, and the connecting block 7 withdraws from the installation groove 9 under the action of the tension spring 10, and drives the positioning block 8 to move out of the installation groove 9, so that the positioning block 8 is located in the card slot. Ring 4, and then the medical staff reversely twists the turntable 5 to further move the connecting block 7 to move it above the supporting groove 18. At this time, the positioning block 8 abuts against the clamping ring 4, thereby completing the fixation of the catheter body 2. In the process of the medical staff reversely twisting the turntable 5, the protrusion 16 at the lower end of the turntable 5 abuts against the groove 17 at the upper end of the mounting ring 11, thereby completing the fixation of the turntable 5. The positioning assembly allows the catheter body 2 to move slightly at the output end of the cystoscope body 1, thereby avoiding bending of the catheter body 2 at the connection with the cystoscope when the angle of the catheter body 2 is adjusted, which affects the clarity of the medical staff's transportation and observation of the cystoscope.
