Abstract

The utility model discloses a plasma double-pole resectoscope which comprises an outer sheath (1), an inner sheath (2) and a hand piece (3), wherein the outer sheath (1) consists of an outer sheath tube (11) and an outer sheath seat (12) arranged at the rear end of the outer sheath tube (11); the outer sheath seat (12) is provided with a water inlet valve (13) and a water outlet valve (14); the surface wall at the front end of the outer sheath tube (11) is provided with a reflow hole (15); the inner sheath (2) is formed by arranging an inner sheath tube (21) on an inner sheath seat (22) arranged behind the inner sheath tube (21); the inner sheath tube (21) is arranged in the outer sheath tube (11); the inner sheath seat (22) can be rotationally connected at the rear end of the outer sheath seat (12); and the hand piece (3) consists of an endoscope (31) and an electrode which are arranged in the inner sheath tube (21). In the utility model, the inner sheath can rotate by 360 degrees in the outer sheath, thus being extremely convenient for operations.

Description

The bipolar resectoscope of plasma

Technical field

This utility model belongs to technical field of medical, specifically is meant a kind of bipolar resectoscope of plasma that is used for the prostatic hyperplasia excision.

Background technology

At present, prostatic hyperplasia is the commonly encountered diseases of elderly men, and excision is a kind of comparatively ideal method.At present, in clinical medicine is used, the resectoscope that carries out micro-wound surgical operation under endoscope replaces traditional mechanical scalpel to undergo surgery, and it compares traditional mechanical scalpel, has cutting fast, amount of bleeding is few, the doctor is clear visual field in operation, and characteristics such as the relative shortening of operating time are widely used in open surgery, minimally invasive surgery, it has not only shortened operating time greatly, and has also alleviated the misery that the patient bore greatly than open surgery.But also there are some shortcomings in traditional resectoscope, can not rotate freely in epitheca as interior sheath, and is just very inconvenient when undergoing surgery operation.

The utility model content

The purpose of this utility model be to provide a kind of in sheath can 360 degree rotate in epitheca the bipolar resectoscope of plasma.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the bipolar resectoscope of plasma, comprise epitheca, interior sheath, hands spare, described epitheca is made up of epitheca pipe and the epitheca seat that is arranged on epitheca pipe rear end, the epitheca seat is provided with water intaking valve and outlet valve, the front end wall of epitheca pipe is provided with return port, the interior sheath seat of sheath pipe back constituted in sheath was arranged on by interior sheath pipe in described, the sheath pipe is arranged in the epitheca pipe in described, the rotating epitheca base rear end that is connected of sheath seat in described, described hands spare is made up of endoscope and electrode, and described endoscope and electrode are arranged in the interior sheath pipe.

Owing to adopted above-mentioned structure, the utlity model has following advantage:

1) because available normal saline as working media, has been saved the operation cost, avoided the generation of water intoxication (TURP syndrome).

2) adopt bipolar electrode, without negative plate, the dynamic CUT system in its bipolar loop, haemostatic effect is fabulous.

3) low-temperature operation, extremely limited thermal break-through, few to the surrounding tissue damage, reduce bladder and stimulated disease, do not damage nervi erigentes.

4) obviously reduce in the art and the bladder irrigation of postoperative, postoperative can not wash (placement double lumen tube) and has reduced band pipe and hospital stays.

5) interior sheath can rotate by 360 degree in epitheca, very is convenient to operation technique.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Fig. 1 is the axonometric chart of the bipolar resectoscope of plasma;

Fig. 2 is the cutaway view of the bipolar resectoscope of plasma shown in Figure 1.

The specific embodiment

As depicted in figs. 1 and 2, the bipolar resectoscope of plasma described in the utility model, comprise epitheca 1, interior sheath 2, hands spare 3, described epitheca 1 is made up of epitheca pipe 11 and the epitheca seat 12 that is arranged on epitheca pipe 11 rear ends, and described epitheca pipe 11 is dismantled and assembled the connection with epitheca seat 12.Epitheca seat 12 is provided with water intaking valve 13 and outlet valve 14, and the front end wall of epitheca pipe 11 is provided with return port 15, and the front end of epitheca pipe 11 is provided with insulation sleeve 16.The interior sheath seat 22 of sheath pipe 21 back constituted in sheath 2 was arranged on by interior sheath pipe 21 in described, sheath pipe 21 is arranged in the epitheca pipe 11 in described, sheath seat 22 rotating epitheca seat 12 rear ends that are connected in described, described interior sheath seat 22 is dismantled and assembled the connection with epitheca seat 12.Described hands spare 3 is made up of endoscope 31 and electrode, described electrode is a bipolar electrode, adopts bipolar electrode just without negative plate, the dynamic CUT system in its bipolar loop, haemostatic effect is fabulous, and described endoscope 31 and electrode are arranged in the interior sheath pipe 21.

In a word; though this utility model has exemplified above-mentioned preferred implementation; but should illustrate; though those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present utility model, otherwise all should be included in the protection domain of the present utility model.
