Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a ureter sheath that facilitates the adjustment of tubing rotation. Background Technology

[0002] Ureteral sheaths are used in urological surgery to establish a passage for endoscopes and other instruments to enter the urinary tract.

[0003] Because endoscopes and other surgical instruments often need to be repeatedly inserted into the tissue through the ureteral guide sheath during the operation, the tube may need to be rotated when the equipment is adjusted. The rotation can only be controlled manually, and the rotation angle control and operation are very inconvenient. When it is necessary to move the guide sheath seat or change the operation gesture, the twisting and entanglement of the connecting tube with the negative pressure drainage bottle must also be considered, which will increase the operation time and increase the risk of the operation. Summary of the Invention

[0004] In view of the aforementioned problems, this application is made to provide a ureteral sheath that facilitates the adjustment of tubing rotation, thereby overcoming or at least partially solving the aforementioned problems.

[0005] This invention discloses a ureteral sheath that facilitates the adjustment of tubing rotation, comprising a Y-shaped body, a guide sheath tube, a guide sheath seat, a dilator seat, and a dilator tube body;

[0006] The expander tube is connected to the expander seat, and the expander seat is embedded in the Y-shaped body; the guide sheath tube is integrally formed with the guide sheath seat, the Y-shaped body is provided with a sealing gasket, and the guide sheath seat is snapped into the Y-shaped body through the sealing gasket;

[0007] When the Y-shaped body is rotated, the Y-shaped body drives the guide sheath seat to rotate simultaneously through the sealing gasket.

[0008] Furthermore, the sealing gasket is made of liquid silicone rubber.

[0009] Furthermore, the guide sheath seat and the Y-shaped body are provided with corresponding locking patterns.

[0010] Furthermore, the Y-shaped body is provided with a pressure relief port, and a pressure relief sleeve is provided at the corresponding position of the pressure relief port.

[0011] Furthermore, it also includes a bending mechanism, which comprises a cam ring, a bending wire, and a bending handle;

[0012] The cam ring is connected to the Y-shaped body, the bending handle is disposed on the cam ring, one end of the bending wire is connected to the cam ring, and the other end of the bending wire is connected to the guide sheath.

[0013] Furthermore, the bending mechanism also includes a steel sleeve, which is disposed at the connection between the cam ring and the bending wire.

[0014] Furthermore, the rotation range of the bending handle is 0-270°.

[0015] Furthermore, the Y-shaped body is also equipped with a sealing cap.

[0016] This application has the following advantages:

[0017] In the embodiments of this application, addressing the shortcomings of existing technologies where adjusting the rotation of the ureteral sheath requires manual operation, which is cumbersome and involves too many considerations, this application proposes a ureteral sheath for easier adjustment of tubing rotation. The sheath includes a Y-shaped body, a guide sheath tube, a guide sheath seat, a dilator seat, and a dilator tube body. The dilator tube body is connected to the dilator seat, which is embedded in the Y-shaped body. The guide sheath tube and the guide sheath seat are integrally formed. The Y-shaped body is provided with a sealing gasket, and the guide sheath seat is engaged with the Y-shaped body via the sealing gasket. When the Y-shaped body is rotated, it simultaneously rotates the guide sheath seat via the sealing gasket. By using the sealing gasket, rotating the Y-shaped body causes the guide sheath tube to rotate, thereby moving the guide sheath seat or changing the operating gesture, eliminating concerns about twisting or tangling with the negative pressure drainage bottle connection tube.

Detailed Implementation

[0023] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0024] The inventors discovered through analysis of existing technologies that: when adjusting the angle of the existing ureteral sheath, it is necessary to manually adjust the rotation of the sheath. When moving the guide sheath or changing the operating gesture, it is also necessary to consider the connection problem with instruments such as the negative pressure drainage bottle connecting tube.

[0025] In the embodiments of this application, addressing the shortcomings of existing technologies where adjusting the rotation of the ureteral sheath requires manual operation, which is cumbersome and involves too many considerations, this application proposes a ureteral sheath for easier adjustment of tubing rotation. The sheath includes a Y-shaped body, a guide sheath tube, a guide sheath seat, a dilator seat, and a dilator tube body. The dilator tube body is connected to the dilator seat, which is embedded in the Y-shaped body. The guide sheath tube and the guide sheath seat are integrally formed. The Y-shaped body is provided with a sealing gasket, and the guide sheath seat is engaged with the Y-shaped body via the sealing gasket. When the Y-shaped body is rotated, it simultaneously rotates the dilator seat via the sealing gasket. By using the sealing gasket, rotating the Y-shaped body causes the guide sheath tube to rotate, thereby moving the guide sheath seat or changing the operating gesture, eliminating concerns about twisting or tangling with the negative pressure drainage bottle connection tube.

[0026] Reference Figure 1-3 This diagram illustrates a ureteral sheath structure that facilitates adjustment of tubing rotation, specifically including:

[0027] Y-shaped main body 101, guide sheath tube 103, guide sheath seat 102, expander seat 104 and expander tube body 202;

[0028] The expander tube 202 is connected to the expander seat 104, and the expander seat 104 is embedded in the Y-shaped body 101; the guide sheath tube 103 is integrally formed with the guide sheath seat 102, the Y-shaped body 101 is provided with a sealing gasket 201, and the guide sheath seat 102 is snapped into the Y-shaped body 101 through the sealing gasket 201;

[0029] When the Y-shaped body 101 is rotated, the Y-shaped body 101 drives the guide sheath seat 104 to rotate simultaneously through the sealing gasket 201.

[0030] It should be noted that the friction of the sealing gasket 201 causes the Y-shaped body 101 and the guide sheath seat 104 to rotate simultaneously, which makes it easy to control the rotation angle and adjust. At the same time, the damping force will not be too large, causing the guide sheath to rotate forcibly and causing tissue damage. The expander seat 104 is embedded and connected to the Y-shaped body 101. When the Y-shaped body 101 rotates, it will also drive the expander seat 104 to rotate, which in turn drives the expander tube 202 to rotate.

[0031] The following will further describe a ureteral sheath that facilitates the adjustment of pipe rotation in this exemplary embodiment.

[0032] In one embodiment of this application, the sealing gasket 201 is made of liquid silicone rubber.

[0033] It should be noted that liquid silicone rubber is a two-component addition silicone rubber that is easy to mold, medically safe, and has suitable viscosity, allowing the Y-shaped body to drive the guide sheath seat to rotate. It is also inexpensive and easy to install.

[0034] In one embodiment of this application, the guide sheath seat 102 and the Y-shaped body 101 are provided with corresponding locking patterns.

[0035] It should be noted that the locking groove is used to make the Y-shaped body 101 and the guide sheath seat 102 interlock, which facilitates the installation and disassembly of the two and ensures a tight installation without gaps after installation.

[0036] In one embodiment of this application, the Y-shaped body 101 is provided with a pressure relief port 105, and a pressure relief sleeve 106 is provided at the corresponding position of the pressure relief port 105.

[0037] It should be noted that when conventional equipment is used for negative pressure adjustment, the operator usually covers the negative pressure hole with their hand. The operator cannot leave the equipment, which is very inconvenient. By covering the pressure relief hole 105 with the pressure relief sleeve 106, the pressure can be adjusted without covering it with the hand, and the pressure is kept stable, which is convenient for the operator.

[0038] In one embodiment of this application, a bending mechanism is also included, which includes a cam ring 302, a bending wire 303, and a bending handle 301.

[0039] The cam ring 302 is connected to the Y-shaped body 101, the bending handle 301 is disposed on the cam ring 302, one end of the bending wire 303 is connected to the cam ring 302, and the other end of the bending wire 303 is connected to the guide sheath 103.

[0040] It should be noted that the bending handle 301 drives the cam ring 302 to rotate, thereby adjusting the length of the bending wire 202, which in turn causes the guide sheath 103 to bend, facilitating lesion localization during surgery. Once the lesion is located and the angle is determined, the angle can be locked. Each time, the endoscope and other surgical instruments only need to enter the tissue along the pre-defined angle to reach the lesion site, eliminating the need for repeated localization and reducing risks.

[0041] In one embodiment of this application, the bending mechanism further includes a steel sleeve 304, which is disposed at the connection between the cam ring 302 and the bending wire 303.

[0042] It should be noted that the steel sleeve 304 makes the bending wire 303 and the cam ring 302 more tightly connected, ensuring the strength of the equipment.

[0043] In one embodiment of this application, the rotation range of the bending handle 301 is 0-270°.

[0044] It should be noted that by limiting the rotation range of the bending handle 301, the bending range of the guide sheath 103 is also limited, thereby ensuring that the bending range is not too high or too low.

[0045] In one embodiment of this application, the Y-shaped body 101 is further provided with a sealing cap 107.

[0046] It should be noted that the sealing cap 107 seals the connection between the Y-shaped body of the device and the expander seat.

[0047] Although preferred embodiments of the present application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

[0048] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or terminal device that includes said element.
