Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a plasma electric cutting and laser enucleation integrated mirror assembly. Background Art

[0002] Currently, there are two types of medical devices used to remove prostate or bladder tumors: plasma resectoscope and laser enucleator.

[0003] Plasma resectoscope is used to remove prostate tissue by energizing the cutting ring to form an electric knife. During the resection operation, there are many blood vessels in the resection layer, so the amount of surgical bleeding is large, and the resection process of plasma resectoscope is longer, but its hemostatic effect is better and complications are not easy to occur.

[0004] Laser enucleation uses optical fiber to generate laser light at the resection site, which causes the prostate tissue to burst and separate from the surgical capsule. During the resection operation, there are fewer blood vessels at the resection level, so the amount of surgical bleeding is less. However, since the contact point between the laser and the prostate tissue is small, the hemostatic effect is poor when using a laser enucleation scope, and it is easy to cause complications such as perforation of the hemostatic site.

[0005] Therefore, there are surgical disadvantages when using plasma resectoscopes and laser enucleation scopes alone to remove prostate or bladder tumors. Existing medical devices cannot have both plasma resectoscope and laser enucleation functions at the same time, allowing surgeons to switch between them according to the surgical situation. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that medical devices used to remove prostate or bladder tumors cannot have both plasma electrocuting and laser enucleation functions, thereby providing an integrated plasma electrocuting and laser enucleation mirror assembly.

[0007] The present invention provides the following technical solutions:

[0008] A plasma cutting and laser enucleation integrated mirror assembly, comprising:

[0009] a body adapted for insertion of an endoscope;

[0010] an optical fiber sleeve connected to the body and arranged parallel to the body;

[0011] The electric cutting ring is connected to the body so that the optical fiber sleeve is located between the endoscope rod and the electric cutting ring. The electric cutting ring is arranged parallel to the body.

[0012] Optionally, the body includes:

[0013] The sleeve is suitable for sleeve-connecting the mirror rod of the endoscope. The sleeve is provided with a sleeve connection portion, and the sleeve connection portion is provided with a cavity suitable for inserting the optical fiber sleeve and the electric cutting ring.

[0014] Optionally, the main body is provided with a sliding block for sliding connection, and the optical fiber sleeve and the electric cutting ring are both connected to the sliding block.

[0015] Optionally, the electrosurgical cutting ring includes:

[0016] The metal sleeve comprises: a front section for arranging a semi-annular electrode and a rear section for connecting to a sleeve portion;

[0017] The end of the optical fiber sleeve is located between the symmetrical front sections.

[0018] Optionally, the rear section is configured to be in an arc shape that matches the optical fiber sleeve.

[0019] The technical solution of the present invention has the following advantages:

[0020] 1. The plasma electrocuting and laser enucleation integrated mirror assembly provided by the present invention includes a main body suitable for inserting an endoscope; an optical fiber sleeve connected to the main body and arranged parallel to the main body; and an electrocuting ring connected to the main body so that the optical fiber sleeve is located between the endoscope shaft and the electrocuting ring, and the electrocuting ring is arranged parallel to the main body.

[0021] The present invention sets an optical fiber sleeve connected to the main body, so that when the component provided by the present invention is in use, after the optical fiber is passed into the optical fiber sleeve, a laser can be formed at the end, thereby enabling the component provided by the present invention to have a laser excision function. By setting an electric cutting ring connected to the main body, when the component provided by the present invention is in use, an electric knife can be formed by energizing the electric cutting ring, thereby enabling the component provided by the present invention to have an ion electric cutting function. Compared with the separate ion electric cutting mirror and laser excision mirror in the prior art, the present invention has both plasma electric cutting function and laser excision function, so that the surgeon can switch between them according to the surgical situation.

The plasma electrocuting and laser enucleation integrated mirror assembly provided by the present invention comprises a main body comprising a sleeve suitable for sleeve-fitting the mirror rod of an endoscope, the sleeve being provided with a sleeve portion, and the sleeve portion being provided with a cavity suitable for inserting the optical fiber sleeve and the electrocuting ring.

[0023] The present invention provides a sleeve connection portion on the main body, which is convenient for installing the optical fiber sleeve and the electric cutting ring.

[0024] 3. The plasma electric cutting and laser enucleation integrated mirror assembly provided by the present invention has a main body provided with a sliding block for sliding connection, and the optical fiber sleeve and the electric cutting ring are both connected to the slider.

[0025] The present invention provides a slider to drive the movement of the optical fiber sleeve and the electric cutting ring, which facilitates the adjustment of the laser at the end of the optical fiber sleeve and the position of the semi-annular electrode, thereby realizing the control of the cutting action during the operation.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] Example 1

[0039] This embodiment provides a plasma cutting and laser scraping integrated mirror assembly, such as Figure 1-Figure 2 As shown, it includes a body 5. This embodiment does not specifically limit the structure of the body 5. Figure 1 As shown, the main body 5 includes a fixed tube, which is suitable for inserting the endoscope 8, and the rod of the endoscope 8 passes through the fixed tube. In this solution, no sleeve is set outside the rod of the endoscope 8. A front grip 9 is fixed to the end of the fixed tube away from the endoscope 8. A slider 3 is also sleeved on the fixed tube, and the slider 3 is located between the front grip 9 and the endoscope 8. A rear grip 10 is provided on the slider 3. When in use, the front grip 9 and the rear grip 10 are held, and the movement of the slider 3 is achieved by moving the rear grip 10.

[0040] The optical fiber sleeve 6 is connected to the slider 3 on the main body 5. The slider 3 is provided with a groove for embedding the optical fiber sleeve 6, and a buckle is provided on the groove. It is arranged parallel to the main body 5 and is used to extend the optical fiber. When in use, the optical fiber is connected to the energy device to form a cutting laser at the front end of the optical fiber sleeve 6. The rear end of the optical fiber sleeve 6 passes through the slider 3, and the part of the optical fiber sleeve 6 located in the slider 3 is bent, so that the operator can drive the optical fiber sleeve 6 to move by moving the slider 3, and then move the cutting laser formed at the end of the optical fiber sleeve 6.

[0041] The electrocuting ring is connected to the slider 3 on the main body 5. The slider 3 is provided with a hole for inserting the electrocuting ring and another buckle is provided on the side of the hole. The optical fiber sleeve 6 is located between the mirror rod of the endoscope 8 and the electrocuting ring, and the electrocuting ring is arranged parallel to the main body 5. The electrocuting ring includes a metal sleeve. The metal sleeve includes a front section 1 with a semi-annular electrode 4 and a rear section 2 suitable for connecting to the main body 5. The front section 1 and the rear section 2 are an integral structure. The symmetrical rear section 2 is arranged in a close fit, and the symmetrical front section 1 is separated. The semi-annular electrode 4 is located between the symmetrical front sections 1. When in use, the metal sleeve is connected to the power equipment through a line to energize it, thereby forming an electric knife with the semi-annular electrode 4. The end of the rear section 2 is connected to the slider 3, so that the operator can drive the electrocuting ring to move by moving the slider 3, thereby moving the position of the semi-annular electrode 4.

[0042] Further, as a preferred solution, Figure 2 As shown, the main body 5 also includes a sleeve, and the sleeve and the fixed tube are an integrated structure. When the main body is inserted into the endoscope 8, the mirror rod of the endoscope 8 is located inside the sleeve, and the end of the sleeve is located between the symmetrical front sections 1. In this solution, the optical fiber sleeve 6 is located between the sleeve and the electrocuting ring. At the same time, in order to facilitate the connection between the optical fiber sleeve 6 and the electrocuting ring and the main body 5, a sleeve connection portion 7 is provided on the sleeve, and the sleeve connection portion 7 is provided with a cavity suitable for inserting the optical fiber sleeve 6 and the electrocuting ring.

[0043] This embodiment does not specifically limit the structure of the sleeve portion 7. As a preferred solution, it is an annular structure with two through holes, wherein the through hole close to the sleeve is used to plug in the optical fiber sleeve 6, and the through hole away from the sleeve is used to plug in the electric cutting ring.

[0044] This embodiment does not specifically limit the position of the end of the optical fiber sleeve 6. Preferably, Figure 1 and Figure 2 As shown, the end of the optical fiber sleeve 6 is located between the symmetrical front sections 1 to avoid interference between the semi-annular electrode 4 and the end of the optical fiber sleeve 6, and interference between the plasma cutting and laser enucleation functions.

[0045] This embodiment does not specifically limit the structure of the metal sleeve. Preferably, in order to reduce the height of the electro-cutting ring and the optical fiber sleeve 6 after being stacked, the rear section 2 of the electro-cutting ring is set to an arc shape that is compatible with the optical fiber sleeve 6, so that the main body 5, the optical fiber sleeve 6 and the electro-cutting ring can all be sleeved inside the inner sheath.

[0046] When in use, this embodiment can control the opening and closing and selection of the two functions of ion electrotomy and laser excision by turning on and off the switches on the lines and optical fibers or the power equipment and energy equipment. In addition, since the electrotomy ring and the optical fiber sleeve 6 are both detachably connected to the main body 5, when in use, the electrotomy ring can be installed without installing the optical fiber sleeve 6 and used separately, or the optical fiber sleeve 6 can be installed without installing the optical fiber sleeve 6 and used separately. When in use, the one-piece mirror assembly provided by this embodiment also needs to be provided with an inner sheath and an outer sheath on the outer surface of the whole, and a space for liquid flow is formed between the inner sheath and the outer sheath. The liquid can be water for cleaning introduced into the human body, or it can be blood drawn from the human body, and an inlet for liquid to enter the space and an outlet for liquid to discharge from the space are provided on the outer sheath. The structure of the above-mentioned inner sheath and outer sheath is the same as that of the inner sheath and outer sheath in the existing electrotomy mirror.

[0047] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
