Abstract

The utility model discloses a smoke-free Leep knife which comprises a knife head, a hollow knife rod, a hilt, a handle, an air receiving mouth and a high-frequency wire. The smoke-free Leep knife is characterized in that two ends of an electric thread are respectively fixed at two sides of the front end of the knife head; the hollow knife rod is connected with the knife head; a smoke intake at one end of the hollow knife rod is positioned on the knife head, and the back end of the hollow knife rod is connected with the hilt and passes outwards the hilt; a hollow handle air tube passes through a handle body; one end of the handle is connected to the hollow knife rod, and the other end of the handle is provided with an air receiving port; the diameter of the handle air tube is matched with the outer diameter of the knife rod; the front end of the handle air tube is connected to the back end of the hollow knife rod, and the back end passes outwards the handle body to form the air receiving port for an external suction device; and the back end of the handle is provided with the high-frequency wire for an external high-frequency generator which is controlled by a switch arranged on the handle. The smoke-free Leep knife is simple in structure and easy to use, can remove the pollution such as smog and odor produced through an air intake when high frequency electric operation is performed, and avoids the pollution of operating room environment, and is beneficial to the health of operating doctors and patients .

Description

Smokeless leep knife

Technical field

This utility model relates to technical field of medical instruments, more specifically relates to a kind of smokeless leep knife.

Background technology

The ultra-high-frequency wave cutter also claims leep knife, be to act on pathological tissues via the most advanced and sophisticated high-frequency electric wave that produces of annular electrode, utilize the biological high heat effect of moment generation, finishing the processing of all kinds of cervical lesionses (as cervical erosion, cervical polyp, precancerous lesions of uterine cervix etc.), and have operation safety, effectively, need not be in hospital, complication is few, advantages such as pain is little are advanced at present treatment cervical disease means, are widely used in medical administration and organisation.

Yet this mode because the conduction of heat makes the vaporization of pathological tissues surface produce smog and stink, had both influenced surgical field of view in therapeutic process, also easily make disperse penetrating odor in the operating room, harm operation doctor and patient's body health.For this reason, the air-breathing modes of external trachea (as installing additional at the vaginal dilator place) that adopt are removed the smog processing more when treatment, but because external trachea is far away apart from the treatment cutter head, effect is not fairly obvious.

Summary of the invention

The purpose of this utility model is to be to provide a kind of smokeless leep knife, this knife structure is simple, easy to use, can be when implementing sharp general operation, connect nuisances such as the smog that produces in the art, stink under the effect of the external aspirator of valve at handle rear end, get rid of by the very near smoking port of distance cutter head TURP silk, have to utilize to purify surgical field of view, operation room air, safeguard doctor, patient body health.

The technical scheme that its technical problem that solves this utility model adopts is: this utility model by cutter head, hollow knife bar, hilt, handle, connect valve and the high frequency lead constitutes.The TURP silk is an electric conductor, can conduct the high-frequency treatment source, the two ends of TURP silk are separately fixed at the both sides of cutter head front end, the hollow knife bar is connected with cutter head, the smoking port of hollow knife bar front end is positioned on the cutter head, the hollow knife rod rear end links to each other with hilt and passes hilt so that be connected with handle, be penetrated with the hollow handle trachea before and after in the handle, handle one end is connected with the hollow knife bar, the handle other end is for connecing QI KOU, the external diameter of handle tracheal diameter and knife bar is complementary, and its front end connects the hollow knife rod rear end, and handle trachea rear end passes handle body formation and connects QI KOU, be used for external aspirator, handle rear end is provided with the high frequency lead, is used for external high frequency generator, and controls by the switch of being located on the handle.

This utility model compared with prior art, have the following advantages and effect: this knife structure is simple, easy to use, can be when implementing the operation of high frequency TURP, the smog that produces, stink etc. are stained by getting rid of the inlet scoop, avoid staining of operating room environment, help operating doctor and patient's health.

Wherein: 1-TURP silk, the 2-cutter head, the 3-smoking port, 4-hollow knife bar, the 5-hilt, the 6-handle, 7-handle trachea, the 8-bat-handle switch, 9-connects QI KOU, the 10-power line.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is described in further detail:

According to Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be known, cutter head 2 is connected with hollow knife bar 4, the two ends of metal TURP silk 1 are individually fixed in the both sides of cutter head 2, TURP silk 1 can be 1 or 3 or 5 or 7 or 9 or 11 or 14 or 17 or 20, TURP silk 1 is arc, linear or polygon, and TURP silk 1 is an electric conductor.The smoking port 3 of hollow knife bar 4 front ends is positioned on the cutter head 2, hollow knife bar 4 is connected with hilt 5, is provided with insulating barrier outside the hollow knife bar 4, and passes hilt 5 rear ends, so that attended operation handle 6, be provided with handle trachea 7 in the handle 6, the external diameter of handle trachea 7 and hollow knife bar 4 are complementary, and its front end is used to connect the rear end of hollow knife bar 4, its rear end is for connecing QI KOU 9, handle 6 is provided with power line 10, is used for external general on the market high frequency generator, and can export control by bat-handle switch 8.

During use, one hand-held handle 6, one hand-held hilt 5, the rear end that passes the hollow knife bar 4 of hilt 5 is inserted into the front end of the handle trachea 7 of handle 6, external aspirator joint is connected on the QI KOU 9, power line 10 is connected to high frequency generator, after connection finishes, TURP silk on the cutter head 21 is aimed at pathological tissues treats, the smog that produce this moment, waste gas will be under the powerful suction of external aspirator, by being positioned on the cutter head 2 smoking port 3 rapidly via hollow knife bar 4, handle trachea 7 is discharged from connecing QI KOU 9, because smoking port is near apart from cutter head, therefore can effectively siphon away harmful gas, reach the purpose of environment purification.
