Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a wireless ureteroscope which is convenient for bending a flexible insertion tube. Background Art

[0002] Clinically, for many patients with ureteral and renal calculi, when the calculi are too large in diameter to be relieved and treated by drugs, surgical treatment is required, such as percutaneous nephrolithotomy, laparoscopic lithotomy, etc. These methods still cause relatively large trauma to patients, and there are possibilities of complications such as kidney bleeding and scar adhesion around the incision, which is not conducive to the postoperative recovery of patients.

[0003] After retrieval, the "ureteroscope" disclosed in the application number "CN202223351635.5" belongs to the same technical field as the present technical solution. This utility model has a drainage groove opened on the side wall of the mirror rod of the ureteroscope. During the lithotripsy operation, without using a ureteral sheath to dilate the ureter, the drainage groove can be used to drain the urine and flushing fluid in the kidney, avoiding kidney infection and increased renal pressure. Therefore, while achieving the surgical purpose, the surgical cost is greatly reduced due to the omission of the ureteral sheath; in addition, when the flexible endoscope is inserted into the ureter, visual insertion can be carried out using the front-end lens of the ureteroscope, and the internal situation of the ureter can be known in time, avoiding damage to the ureter or ureteral avulsion during the insertion of the endoscope. Thus, the surgical safety is improved.

[0004] Currently, the rigid ureteroscopes used clinically have a non-bendable mirror tube body and lens. When inserted into the ureter, the insertion is often difficult or even fails due to poor smoothness. Or after insertion, the lens end cannot be bent, resulting in a greatly limited observation field of view and an observation blind area. Or there is a power supply and a data transmission line, which affects the quality of diagnosis and treatment. Content of the Utility Model

[0007] As a preferred embodiment of the wireless ureteroscope of the utility model which is convenient for bending of the soft insertion tube, the steel wire of the steel wire rope assembly passes through the interior of the clamping copper column assembly, the wire drawing docking assembly and the spring.

[0008] As a preferred embodiment of the wireless ureteroscope of the utility model which is convenient for bending of the soft insertion tube, the steel wire portion at the end of the steel wire rope assembly is welded and fixed to the rotating assembly.

[0009] As a preferred wireless ureteroscope of the utility model that facilitates the bending of a soft insertion tube, the clamp valve assembly includes a clamp inlet, a through tube and a docking nozzle, the clamp inlet is connected to the end of the through tube, and the other end of the through tube is connected to the docking nozzle.

[0010] As a preferred embodiment of the wireless ureteroscope of the utility model which is convenient for bending of the soft insertion tube, the end of the wireless WIF component is provided with a male head which matches the female head component.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model realizes the bending of the flexible insertion tube by providing a rotating assembly, a wire drawing docking assembly and a wire rope assembly, enabling the lens to enter through the direct combustion channel without additional incision or drilling, greatly reducing the damage to the patient during the operation and facilitating the postoperative recovery of the patient. The lens observes with the bending, greatly increasing the inspection and observation range without blind spots in the field of vision. Further, by providing a wire drawing docking assembly, it effectively avoids the loosening of the wires of the wire rope assembly caused by the rotation of the rotating assembly, resulting in the inability to control the bending of the end of the flexible insertion tube. During use, by rotating the rotating assembly, the wire drawing docking assembly pulls the wires of the wire rope assembly through the capillary tube, causing the flexible insertion tube to bend.

[0015] In addition, by connecting the fixed rubber sleeve between the flexible insertion tube and the handle housing, it can play a role in protection and sealing, thus preventing the patient's secretions from seeping into the interior of the handle housing through the gaps, which may affect the use of the ureteroscope.

[0016] Moreover, the biopsy forceps can enter the through tube 1802 through the insertion forceps inlet 1801. The smooth inner wall of the through tube 1802 allows the biopsy forceps to change direction and enter the docking nozzle 1803. Since the end of the docking nozzle 1803 is docked with the flexible insertion tube 12, the biopsy forceps can quickly enter the flexible insertion tube 12, facilitating the penetration of the biopsy forceps, and thus enabling the treatment of the patient through the biopsy forceps.
