Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

When laparoscopic and thoracoscopic operations are performed, carbon dioxide gas is required to be continuously injected into the abdominal cavity or the thoracic cavity to expand the abdominal cavity and the thoracic cavity, so that an operation visual field and a sufficient operation space are provided for an operator, smoke is generated when the electric hook performs electrosection or electrocoagulation, and the smoke gas is easy to dissipate and has small influence on the operation visual field.

However, when cystoscopy is performed, it is usually necessary to inject a non-conductive liquid medium into the bladder to fill the bladder, so as to provide the surgical field and sufficient surgical space for the surgical personnel, during the operation, tissue fluid and dirty blood are generated, and smoke bubbles are generated when the electric hook performs electrosection or electrocoagulation, and the tissue fluid, the blood and the smoke can pollute the liquid medium injected into the bladder and affect the field of view of the surgical personnel, so that the tissue fluid, the blood and the smoke need to be discharged and clean liquid medium needs to be re-injected to ensure the surgical field and sufficient surgical space.

For the above reasons, referring to fig. 1 to 2, the present application provides an electric hook 100, and the electric hook 100 can be applied to a cystoscopic operation.

The electric hook 100 includes a shaft assembly 110 and an electric hook head 120. The electric hook head 120 is generally used for shifting and separating tissues, so that the observation of surgical personnel is facilitated and a space is created for subsequent surgical operation, and the electric hook head 120 can play a role in electric coagulation and electric excision after being electrified, for example, when the electric hook head 120 is switched on with a large current, the temperature of the electric hook head 120 is greatly increased, and the high-temperature electric hook head 120 enables tissue components to rapidly expand and burst to be separated, so that the tissue separation is realized, and the electric excision effect is achieved; when the electric hook head 120 is switched on with a small current, the temperature of the electric hook head 120 rises, at the moment, the temperature of the electric hook head 120 is lower than that during electric cutting, and tissue fluid near the electric hook head 120 is evaporated by high temperature generated by the electric hook head 120, so that the effects of hemostasis and coagulation are achieved, and the electric coagulation effect is achieved.

The electric hook head 120 can be in a sickle shape or a crescent shape, so as to reduce the contact area between the electric hook head 120 and the tissue, facilitate rapid and accurate cutting of the tissue and coagulation of the wound, and avoid the phenomenon that the current of the electric hook head 120 is conducted to the surrounding normal tissue due to the large contact area between the electric hook head 120 and the tissue, thereby causing secondary injury. The electrical hook head 120 may be made of conductive metal.

The surface of the electric hook head 120 can be coated with a conductive ceramic coating, and the ceramic coating can effectively prevent the tissue of the electric hook head 120 from being adhered to the electric hook head 120 when the electric hook head 120 is separated and cut, thereby reducing the side damage generated in the operation process and improving the operation effect.

The rod assembly 110 includes a connecting rod 111, an aspiration channel 113 and an injection channel 115, wherein the aspiration channel 113 and the injection channel 115 are disposed at an interval on the connecting rod 111. Thus, during operation, the liquid-phase medium polluted by tissue fluid, blood and smoke can be sucked out through the suction pipeline 113, and the clean liquid-phase medium is injected through the injection pipeline 115, so that the contaminated liquid-phase medium is prevented from influencing the operation visual field of the medical staff.

The suction duct 113 has a first inlet 1131 and a first outlet 1133, the first inlet 1131 and the first outlet 1133 are respectively distributed along the length direction of the connecting rod 111, and both the first inlet 1131 and the first outlet 1133 are exposed to the connecting rod 111. In this way, during an operation, the liquid-phase medium contaminated by tissue fluid, blood and smoke may be sucked into the suction conduit 113 through the first inlet 1131 and discharged through the first outlet 1133, so as to prevent the contaminated liquid-phase medium from affecting the operation view of the medical staff.

The injection duct 115 has a second inlet 1151 and a second outlet 1153, the second inlet 1151 and the second outlet 1153 are respectively distributed along the length direction of the connecting rod 111, and both the second inlet 1151 and the second outlet 1153 are exposed to the connecting rod 111. The first inlet 1131 and the second outlet 1153 are disposed at the same end of the connecting rod 111 and spaced apart, and the first outlet 1133 and the second inlet 1151 are spaced apart. Thus, when an operation is performed, the liquid-phase medium can be injected into the injection pipeline 115 through the second inlet 1151 and flow into the bladder through the second outlet 1153, so that the bladder is inflated, an operation visual field can be created, the injected liquid-phase medium can clean and neutralize the dirty tissue fluid or blood generated during the operation, and the operation visual field of medical staff is prevented from being influenced by the contaminated liquid-phase medium. The injected liquid-phase medium may be a clear and non-conductive liquid, such as a 5% strength medical glucose injection.

In addition, the electric hook head 120 is connected to the linkage 111, and the electric hook head 120, the first inlet 1131, and the second outlet 1153 are all located at the same end of the linkage 111. In this way, the first inlet 1131 and the second inlet 1151 may be close to the electric hook head 120, so that the first inlet 1131 may suck away the contaminated liquid-phase medium near the electric hook head 120 relatively quickly, and the operation field may be improved. Meanwhile, clean liquid-phase medium can be directly injected to the vicinity of the electric hook head 120 through the second outlet 1153, the working area of the electric hook head 120 is cleaned, and the operation visual field is further improved.

In some embodiments, the electric hook 100 may further include a first plug 121 and a second plug 123, and the connecting rod 111 may be provided with a first groove 1111 and a second groove 1113 on an outer circumferential surface thereof. The first recess 1111 is communicated with the first outlet 1133, the first plug 121 is disposed in the first recess 1111, and the first plug 121 can selectively close or open the first outlet 1133.

When the polluted liquid-phase medium does not need to be sucked out by using the electric hook 100, the first outlet 1133 can be closed by the first plug 121, so that the suction pipe 113 is closed, and the probability of dust entering the suction pipe 113 is reduced.

The second groove 1113 is communicated with the second inlet 1151, the second plug 123 is disposed in the second groove 1113, and the second plug 123 can selectively close or open the second inlet 1151.
