The utility model discloses a setting is in the first elasticity latch of the inboard of insulating cover and the cooperation of the second elasticity latch of setting in the electrode outside, and the doctor can draw in the insulating cover with blunt electrode, avoids blunt electrode to damage the nephroscope stretching into the puncture passageway in-process, pulls out blunt electrode from insulating cover again after blunt electrode reaches the target position. The blunt electrode arranged on the electrode is spherical, so that the contact area of the blunt electrode and the kidney channel tissue is increased, the electrocoagulation hemostasis area is increased, and the side injury caused by the invagination of the electrode head end to the kidney tissue is avoided. Meanwhile, the connecting inner core arranged on the electrode can be connected with a disposable electric knife handle. When in use, the linking inner core is connected with the handle of the disposable hand-controlled electrotome pen, and the electric coagulation can be used as common electrotome.

Preferably, the outer side of the insulating sleeve is provided with anti-skid grains.

The utility model discloses a set up the anti-skidding line in the insulating cover outside, increased the frictional force between doctor's finger and the insulating cover, be convenient for the doctor changes the relative position between insulating cover and the electrode.

Preferably, the diameter of the insulating sheath is 2mm to 3 mm.

The utility model adopts the insulating sleeve with the diameter of 2mm to 3mm, thereby ensuring the easy passing of the nephroscope and other surgical instruments.

Preferably, the insulating sleeve is made of medical ABS material.

The utility model discloses following beneficial effect has:

the utility model discloses a cooperation of first elasticity latch and second elasticity latch makes the doctor can draw in the blunt electrode in the insulating cover, avoids the blunt electrode to damage the nephroscope stretching into the puncture passageway in-process. The blunt electrode arranged on the electrode is spherical, so that the contact area of the blunt electrode and the kidney channel tissue is increased, the electrocoagulation hemostasis area is increased, and the side injury caused by the invagination of the electrode head end to the kidney tissue is avoided. Meanwhile, the connecting inner core arranged on the electrode can be connected with the disposable electrotome handle, so that the operation cost is reduced, the requirement of the state on hospital infection control is ensured by disposable design, and the potential infection risk is avoided. The utility model discloses simple structure and practical convenient has alleviateed medical staff's the work degree of difficulty, has improved the efficiency and the patient safety of medical treatment operation.

In the figure: 1-an electrode; 2-an insulating sleeve; 3-a blunt electrode; 4-connecting the inner core; 5-a first elastic latch; 6-second elastic latch; 7-anti-skid lines.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

Examples

Referring to fig. 1 to 2, the utility model comprises an electrode 1 and an insulating sleeve 2 sleeved outside, wherein the insulating sleeve 2 is made of medical ABS material. The diameter of the insulating sleeve 2 is 2mm to 3mm, so that the easy passing property of a nephroscope and other surgical instruments is ensured. An insulating sleeve 2 made of hard material is sleeved outside the electrode 1, so that the angle and the direction of the head end of the electrode 1 can be controlled by a handheld handle after entering through the nephroscope cavity. The anti-skid grains 7 are arranged on the outer side of the insulating sleeve 2, so that the friction force between the fingers of a doctor and the insulating sleeve 2 is increased, and the doctor can conveniently change the relative position between the insulating sleeve 2 and the electrode 1.

Further referring to fig. 2, the inner side of the insulating sleeve 2 is provided with a first elastic latch 5, and the outer side of the electrode 1 is provided with a second elastic latch 6 corresponding to the first elastic latch 5. Through setting up at the first elasticity latch 5 in insulating cover 2's inboard and the cooperation of the second elasticity latch 6 of setting in the electrode 1 outside, the doctor can draw in insulating cover 2 with blunt electrode 3 in, avoids blunt electrode 3 to damage the nephroscope stretching into the puncture passageway in-process, and the doctor pulls out blunt electrode 3 from insulating cover 2 again after blunt electrode 3 reaches the target position. Insulating cover 2 is passed and be equipped with blunt electrode 3 to the one end of electrode 1, and blunt electrode 3 is spherical and blunt electrode 3's diameter is less than insulating cover 2's diameter, has increased the area of contact of blunt electrode 3 with kidney passageway tissue through adopting spherical blunt electrode 3, increases the electric coagulation hemostasis area and avoids 1 head end of electrode to sink into to the kidney tissue and the vice damage that arouses, has improved hemostatic effect.

Referring further to fig. 1, the other end of the electrode 1 passes through the insulating sheath 2 and is provided with a connecting inner core 4, and the connecting inner core 4 can be inserted into the handle of the electric knife. The connecting inner core 4 arranged on the electrode 1 can be connected with a disposable electric knife handle. When the electric coagulation scalpel is used, the link inner core is connected with the handle of the disposable manual control electric scalpel pen, the electric coagulation scalpel can be used as a common electric scalpel, the operation cost is reduced, the requirement of the state on hospital infection control is met through the disposable design, and the potential infection risk is avoided.
