Background
The electric snare is widely used for treating human tissues in endoscopic diagnosis and treatment, and mainly comprises an outer sheath tube, metal snares respectively arranged at two ends of the outer sheath tube and an operating handle. When the endoscope is used for diagnosis and treatment, an operator controls the snare to extend, rotate and retract from the outer sheath tube through the operating handle, the focus tissue is sleeved in the metal loop, high-frequency current is introduced into the metal loop, and the focus tissue is treated by the metal loop.
The existing electric snare can only sleeve the focus tissue into the metal loop to perform excision, and for some focus tissues which are not convenient to sleeve the metal loop, other instruments (such as an electric knife) are needed to be used for treatment, so that the instruments need to be frequently replaced in endoscopic surgery, the operation efficiency of doctors is reduced, and the operation time is relatively long.
SUMMERY OF THE UTILITY MODEL
To the defect that exists among the above-mentioned prior art, the utility model aims to solve the technical problem that a medical electricity snare that can improve doctor operating efficiency, it is long when shortening the operation is provided.
In order to solve the technical problem, the utility model provides a medical electric snare, which comprises an outer sheath tube and a snare; the outer sheath tube is a hose, the ring sleeve is an elastic linear ring body, the ring sleeve is arranged at the left end of the outer sheath tube in a movable fit mode, an end clamping seat is fixed at the right end of the outer sheath tube, and a rotatable operating handle is arranged on the end clamping seat; the operating handle is provided with a push-pull seat capable of sliding left and right, an electrical connector is fixed on the push-pull seat, a conductive pull rod is arranged in the outer sheath tube, the right end of the pull rod is fixedly connected with the push-pull seat and is electrically communicated with the electrical connector on the push-pull seat, and the left end of the pull rod is fixedly connected with the snare and is electrically communicated with the snare; the method is characterized in that:
the left end opening of the outer sheath tube is provided with a rotatable ring sleeve seat, the ring sleeve seat is provided with an upper through hole and a lower through hole which are communicated from left to right, the upper part and the lower part of the ring sleeve respectively penetrate through the two through holes on the ring sleeve seat in a sliding fit mode, and the left end of the ring sleeve is provided with a ring tip which protrudes leftwards.
Furthermore, a liquid injection port communicated with the cavity of the outer sheath tube is formed in the end clamping seat.
The utility model provides a medical electricity snare can adopt traditional snare mode to deal with focus tissue, can also utilize the snare seat to provide the support for the snare to make the snare withdraw back, the ring point can keep relatively fixed state, can cut focus tissue as the electrotome with the ring point, reduce the frequency of changing the apparatus in the art, can improve doctor operating efficiency, it is long when shortening the operation.

Detailed Description
The following description is provided for the embodiments of the present invention, but the present invention is not limited to the embodiments, and all the similar structures and similar variations of the present invention can be adopted to fall into the protection scope of the present invention.
As shown in fig. 1-3, the embodiment of the present invention provides a medical electric snare, which comprises an outer sheath tube 1 and a snare 2; the sheath tube 1 is a hose, the snare 2 is an elastic linear ring body, the snare 2 is arranged at the left end of the sheath tube 1 in a movable fit mode, an end clamping seat 6 is fixed at the right end of the sheath tube 1, a liquid injection port 61 communicated with the lumen of the sheath tube is formed in the end clamping seat, and a rotatable operating handle 3 is arranged on the end clamping seat;
the operating handle 3 is provided with a push-pull seat 5 capable of sliding left and right, an electrical connector 8 is fixed on the push-pull seat, a conductive pull rod 4 is arranged in the outer sheath tube 1, the right end of the pull rod 4 is fixedly connected with the push-pull seat 5 and is electrically communicated with the electrical connector 8 on the push-pull seat, and the left end of the pull rod 4 is fixedly connected with the snare 2 and is electrically communicated with the snare 2;
the left end opening of the outer sheath tube 1 is provided with a rotatable ring sleeve seat 7, the ring sleeve seat 7 is provided with a through hole which is communicated from top to bottom and from left to right, the upper part and the lower part of the ring sleeve 2 respectively penetrate through the two through holes in the ring sleeve seat 7 in a sliding fit manner, the left end of the ring sleeve 2 is provided with a ring tip 21 which protrudes to the left, and the ring tip 21 is formed by bending the body of the ring sleeve.
The embodiment of the utility model provides a be arranged in scope art to handle focus tissue, its using-way as follows:
the electric connector 8 on the push-pull seat is connected to a high-frequency current output device, the outer sheath tube 1 is inserted into an instrument channel on the endoscope, the snare 2 reaches the position of focal tissue in a human body, the operating handle 3 is positioned outside the human body, the push-pull seat 5 is connected with the snare 2 through the pull rod 4, the push-pull seat 5 is controlled to slide back and forth, the snare 2 can be driven to extend out and retract, the operating handle 3 rotates relative to the outer sheath tube 1, and the snare 2 can be driven to rotate.
When some focus tissues which can be sleeved in the snare 2 are treated, the precursor extends the snare 2 (in the state shown in fig. 1 and 2), rotates, sleeves the focus tissues in the snare 2, retracts the snare 2, and is introduced with high-frequency current to cut the focus tissues, flushing fluid can be injected through the fluid injection port 61 on the end clamping seat (at the moment, the introduction of the high-frequency current is stopped), a target part is flushed, and coked tissues adhered to the snare 2 can be flushed.
When some lesion tissues which are inconvenient to be sleeved in the snare are treated, the precursor enables the snare 2 to retract (the state shown in figure 3), the snare is supported by the snare seat 7, so that after the snare retracts, the loop tip 21 can keep a relatively fixed state, then high-frequency current is introduced into the snare, and the loop tip 21 is used as an electric knife to cut the lesion tissues.
