Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, specifically to a handle structure and a medical planing device. Background Technology

[0002] Medical shaving devices are used in surgical procedures to cut and process soft tissues. Existing medical shaving devices mainly consist of a power unit, a power handle, and a shaving head. During hysteroscopic surgery, saline solution is injected into the uterine cavity to inflate it, thereby expanding the endoscope's field of vision and providing operating space for the shaving head. If the uterine cavity is not inflated, and the shaving head is already inserted, the uterine cavity and the external waste fluid collector form a connected cavity through the handle and management channel. However, the saline solution injected into the uterine cavity is automatically forced into the waste fluid collector due to increased pressure, preventing uterine inflatation and affecting the procedure. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the main purpose of this utility model is to provide a handle structure and a medical shaving device, which aims to solve the problem that if the blade is inserted into the uterine cavity first when using a traditional medical shaving device, it may cause the uterus to fail to expand, making the surgery impossible.

[0004] To achieve the above objectives, the present invention provides a handle structure comprising:

[0005] A handle housing, wherein an attraction channel is formed within the handle housing;

[0006] A valve structure is provided within the suction channel and is used to open and close the suction channel.

[0007] An adjusting component is connected to the valve structure and is at least partially exposed on the outside of the handle housing. The adjusting component moves under the action of an external force, causing the valve structure to open and close the suction channel.

[0009] Optionally, the suction channel includes a main suction channel, a suction side channel located on one side of the main suction channel, and a through hole connecting the main suction channel and the suction side channel, wherein the valve structure moves to open or close the through hole.

[0010] Optionally, the valve structure has a guide channel formed thereon. The valve structure can be moved such that the guide channel can be connected to the through hole to conduct the main suction channel and the suction side channel, and the guide channel can be in a closed state to block the main suction channel and the suction side channel.

[0011] Optionally, the guide channel extends axially along the handle housing and has a first opening and a second opening that are opposite to each other along its axial direction.

[0012] The suction-side channel has a first end and a second end that are arranged opposite to each other along the axial direction of the handle housing. The first end is blocked, and the second end is adapted to communicate with the waste liquid collector. The through hole is provided on one side of the suction-side channel.

[0013] The valve structure moves axially along the handle housing to have a blocked state that seals the through hole, and a connected state that allows the first opening to communicate with the through hole and allows the connecting channel to connect the main suction channel and the suction side channel.

[0014] Optionally, when in the blocked state, the first end of the suction-side channel is positioned to abut against and block the first opening.

[0015] Optionally, in the direction from the first opening toward the second opening, the inner diameter of the guide channel is gradually reduced at the end near the first opening.

[0033] This utility model provides a handle structure 100, which is suitable for medical planing devices. For details, please refer to... Figure 1 , Figure 2 and Figure 4In this embodiment, the handle structure 100 includes a handle housing 1, a valve structure 2, and an adjusting component 3. A suction channel is formed inside the handle housing 1. The valve structure 2 is disposed inside the suction channel and is used to open and close the suction channel. The adjusting component 3 is connected to the valve structure 2 and is at least partially exposed outside the handle housing 1. The adjusting component 3 moves under the action of external force, driving the valve structure 2 to open and close the suction channel.

[0034] In this embodiment, a suction channel is formed within the handle housing 1, through which waste fluid generated during the procedure can be aspirated. A valve structure 2 is provided on the suction channel, which controls its opening and closing. During the procedure, when injecting saline or other therapeutic fluids into the uterine cavity, the suction channel can be closed first via the valve structure 2, preventing the saline from automatically being pushed back into the waste fluid collector, thus ensuring the uterine cavity can expand and making the surgical blade easier to operate. Furthermore, an adjustment component 3 is provided, allowing the operator to manually operate the valve structure 2 to control the opening and closing of the suction channel. During the procedure, the operator can adjust the suction channel's opening and closing at any time, making operation simple and convenient, and ensuring better surgical results.

[0035] It is understood that there are many ways to achieve the opening and closing of the suction channel. In one embodiment, the valve structure 2 may include a movable sealing cover, which can be rotated or moved linearly to block and open the suction channel, thereby achieving blocking and opening along the cross-section of the suction channel through the sealing cover.

[0036] In another embodiment, preferably, combined with Figure 2 and Figure 4As shown, the suction channel is arranged along the axial direction of the handle housing 1. The handle housing 1 is generally cylindrical. The front end of the handle housing 1 along its axial direction is adapted to connect with a front insertion component (such as a blade structure), and the rear end of the handle housing 1 along its axial direction is adapted to connect with a cable structure. Therefore, under the guiding action of the front insertion component, the fluid in the uterine cavity can flow axially into the suction channel and into the waste fluid collector. The valve structure 2 has a movable stroke along the axial direction of the handle housing 1 to open and close the suction channel. The opening and closing of the suction channel is controlled by the linear reciprocating movement of the valve structure 2 along its axial direction. Furthermore, since the space along its axial direction of the handle housing 1 is relatively large, moving the valve structure 2 along the axial direction of the handle housing 1 provides sufficient space for the valve structure 2 without increasing the radial volume of the handle housing 1, ensuring a more compact structure and smaller size for the handle structure 100.

[0037] Among them, such as Figure 3 and Figure 5 As shown, the suction channel includes a main suction channel 11, a suction side channel 12 located on one side of the main suction channel 11, and a through hole 13 connecting the main suction channel 11 and the suction side channel 12. The valve structure 2 moves to open or close the through hole 13. It can be understood that, to facilitate the connection between the waste liquid collector and the suction channel, a connector is provided on one side of the handle housing 1. The connector is hollow, and its inner cavity forms the suction side channel 12. By opening and closing the through hole 13 through the valve structure 2, the connection between the main suction channel 11 and the suction side channel 12 is more easily achieved.

[0038] Furthermore, such as Figure 4 and Figure 5 As shown, a guide channel 213 is formed on the valve structure 2. The valve structure 2 can be moved such that the guide channel 213 can communicate with the through hole 13 to connect the main suction channel 11 and the suction side channel 12, and the guide channel 213 can be closed to block the main suction channel 11 and the suction side channel 12. By forming the guide channel 213 on the valve structure 2, and by moving the valve structure 2 to connect or block the guide channel 213 with the through hole 13, the opening and blocking of the suction channel can be achieved.

[0039] Furthermore, the guide channel 213 extends axially along the handle housing 1, having a first opening 211 and a second opening 212 arranged opposite to each other along its axial direction. The suction-side channel 12 has a first end and a second end arranged opposite to each other along the axial direction of the handle housing 1. The first end is blocked, and the second end is adapted to communicate with a waste fluid collector. The through hole 13 is located on one side of the suction-side channel 12. Liquid aspirated from the uterine cavity can flow through the main suction channel 11 to the through hole 13, and then into the suction-side channel 12, where it is guided by the suction-side channel 12 and flows into the waste fluid collector. The valve structure 2 moves axially along the handle housing 1 to have a blocked state that blocks the through hole 13, and a connected state that allows the first opening 211 to communicate with the through hole 13 and allows the guide channel 213 to connect the main suction channel 11 and the suction-side channel 12. By moving the valve structure 2, the first opening 211 of the valve structure 2 can be moved to communicate with the through hole 13, thereby connecting the main suction channel 11 and the suction side channel 12. Furthermore, by moving the valve structure 2, the through hole 13 can be blocked, preventing liquid in the main suction channel 11 from entering the suction side channel 12. When injecting saline into the uterine cavity, the pressure of the liquid within the uterine cavity limits the liquid to entering only the main suction channel 11. This allows the uterine cavity to expand upon subsequent injections of saline, facilitating better surgical procedures. At the end of the procedure, the valve structure 2 can be moved to the open state, allowing liquid in the main suction channel 11 to enter the suction side channel 12 and then into the waste fluid collector for waste fluid recovery. This makes the expansion and contraction of the uterine cavity easier to control during the procedure, improving surgical efficiency.

[0040] Moreover, preferably, combined with Figure 4 and Figure 5 As shown, when in the blocked state, the first end of the suction-side channel 12 is positioned to abut against and block the first opening 211. That is, when the valve structure 2 blocks the through hole 13, the inner wall of the suction-side channel 12 is also positioned to block the first opening 211, so that liquid forms a first blockage between the valve structure 2 and the through hole 13, and a second blockage between the first opening 211 and the inner wall of the suction-side channel 12, ensuring a better sealing effect and preventing some liquid from entering the guide channel 213 and causing leakage when the valve structure 2 is in the blocked state.

[0041] Specifically, the valve structure 2 includes a guide cylinder 21 and a sealing element sleeved on the outer periphery of the guide cylinder 21. The guide cylinder 21 is movably sleeved on the inner side of the suction-side channel 12, and the sealing element abuts against the inner wall of the guide cylinder 21 and the suction-side channel 12. The shape of the guide cylinder 21 matches the shape of the inner cylinder of the suction-side channel 12, both being approximately cylindrical. The guide cylinder 21 moves along the suction-side channel 12 to switch between the blocking state and the conducting state. When in the blocked state, the peripheral wall of the guide tube 21 is blocked at the through hole 13, and the first opening 211 of the guide tube 21 abuts against the inner wall of the first end of the suction side channel 12; when in the open state, the first opening 211 of the guide tube 21 is spaced apart from the first end of the suction side channel 12, and the through hole 13 is located within the space, so that the first opening 211 communicates with the through hole 13. Therefore, the liquid in the main suction channel can pass through the through hole 13 and enter the guide channel 213 from the first opening 211, and then flow into the suction side channel 12 to flow to the waste liquid collector.

[0042] Preferably, the sealing element is a sealing ring, and two sealing rings are provided, which are spaced apart and sleeved on the outer periphery of the guide cylinder 21. When in the blocked state, the through hole 13 is located between the two sealing rings. Liquid seeping into the space between the guide cylinder 21 and the suction-side channel 12 through the through hole 13 is blocked by the sealing effect of the two sealing rings, preventing liquid from entering the suction-side channel 12, thus improving the sealing effect.

[0043] Furthermore, in the direction from the first opening 211 toward the second opening 212, the inner diameter of the guiding channel 213 gradually decreases at the end near the first opening 211. That is, the inner diameter of the guiding channel 213 at the end near the first opening 211 is funnel-shaped, so that when in the conducting state, liquid can more easily enter the first opening 211.

[0044] For the adjustment component 3, preferably, it is combined with Figure 3 and Figure 5 As shown, the adjustment component 3 includes an adjustment boss 31 protruding from the outer periphery of the guide cylinder 21. The handle housing 1 has an adjustment hole on one side corresponding to the suction side channel 12. At least a portion of the adjustment boss 31 can be exposed from the adjustment hole to the outside of the handle housing 1, thereby facilitating the operator to operate the adjustment boss 31.

[0045] Preferably, the adjusting boss 31 is integrally formed with the guide cylinder 21, and a concave-convex structure is provided on the end face of the adjusting boss 31 to increase the friction between the hand and the adjusting boss 31, making it easier for the operator to push and operate the adjusting boss 31. Moreover, the movement of the adjusting boss 31 can be directly converted into the movement of the guide cylinder 21, making the operation simple and effortless. During the operation, it is also convenient for the operator to push the adjusting boss 31 to move back and forth along the axial direction of the handle housing 1, making the operation more convenient.

[0046] This utility model also provides a medical shaving device, which includes the aforementioned handle structure 100. Through the handle structure 100, the medical shaving device can better control the accumulation and discharge of fluid in the uterine cavity during use, making the surgical operation smoother and effectively improving surgical efficiency and quality.

[0047] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structure made using the contents of the present utility model specification and drawings, or directly or indirectly applied to other related technical fields, are similarly included within the patent protection scope of the present utility model.
