Technical Field

The utility model relates to the field of medical equipment, more specifically say, it relates to a peritoneum rear cavity expander for uropoiesis surgery minimal access surgery.

Background

The urinary surgery endoscopic surgery approach needs to establish a retroperitoneal cavity in advance, the retroperitoneal cavity is established by adopting a Hasson opening technology at present, the skin is longitudinally incised by about 2cm under the 12 th costal edge of the posterior axillary line, the blunt separation base layer and the lumbar dorsal fascia of a long curved vessel forceps are stretched into an indication finger to push away the peritoneum, the palm part of the No. 8 glove is cut off, one end of the glove is fastened and fixed on an injector by a silk thread, the retroperitoneal cavity is placed, 800ml of the retroperitoneal forceps is inflated, and the balloon is pulled out after the expansion state is maintained for 3-5 min. The volume of the injector is 50ml generally, the injector needs to be separated for inflation for many times and then pumped, the repeated separation is easy to leak air, and the metering is inaccurate.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a solve uropoiesis surgery for minimal access surgery peritoneal rear cavity expander of above-mentioned problem, convenient for material collection need not to separate repeatedly and inflates, and the measurement is accurate, the operation of being convenient for.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the retroperitoneal dilator for minimally invasive urinary surgery comprises an injector, a three-channel rotary valve, an air pipe and a balloon, wherein an air inlet hole is formed in the nipple face at the top end of the injector, one end of the injector nipple and one end of the air pipe are respectively connected to two communicated ports of the three-channel rotary valve, and the other end of the air pipe is connected with the balloon.

The utility model discloses further improve technical scheme and be, the syringe nipple is located the top avris, and the inlet port is located syringe nipple below position. The middle finger can conveniently block the air inlet when the user operates with one hand.

The utility model discloses further improve technical scheme be, be equipped with a sealing washer on the inlet port. Effectively preventing air leakage.

The utility model discloses further improve technical scheme be, the trachea is disposable silica gel catheter. The materials are convenient to take and use.

The utility model discloses further improve technical scheme be, the inflatable 600-.

The utility model discloses further improve technical scheme be, the syringe volume is 50 ml.

The utility model discloses beneficial effect:

the utility model discloses take medical treatment parts commonly used combination and form, convenient for material collection, simple structure. The three-channel rotary valve is rotated to be closed after 50ml of gas is injected into the injector for the first time, air leakage is avoided, fingers open an air inlet hole of the injector to pump air to 50ml, then the three-channel rotary valve is rotated to be opened, simultaneously the fingers block the air inlet hole, and gas is injected into the balloon, and the cycle is carried out for 12-16 times, so that the gas filling amount of 600-800ml in the balloon is completed, the peritoneum after expansion is completed, the gas filling amount is accurate, and the operation is simple, convenient and light.

Drawings

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a schematic view of the structure of the nipple surface at the top end of the injector of the present invention.

Detailed Description

As shown in figure 1 and figure 2, the utility model discloses a sacculus 4 of medical 50ml volume syringe 1, three channel stopcocks 2, trachea 3 (disposable silica gel catheter) and inflatable 600-containing 800ml, 1 top nipple face of syringe is equipped with inlet port 6, syringe nipple 5 is located the top avris, inlet port 6 is located syringe nipple below position, be equipped with a sealing washer 7 on the inlet port 6, syringe nipple 5, trachea 3 one end are connected respectively on the communicating both ends mouth of three channel stopcocks 2, sacculus 4 is connected to the trachea 3 other end.

After establishing the peritoneum rear chamber according to the open technique of Hasson, will the utility model discloses the peritoneum rear chamber is put into to the sacculus, rotatory three channel rotary valve is closed after 50ml gas is injected into to the syringe for the first time, avoids gas leakage, and the open syringe inlet port of finger, bleed to 50ml, and rotatory three channel rotary valve is opened again, and the inlet port is stopped up to the finger simultaneously, injects gas once more in the sacculus, so circulate 12-16 times, accomplish 600 in the sacculus and add 800 ml's gas filling volume, accomplish the expansion peritoneum, the inflation volume is accurate, need not separate repeatedly, and is easy and simple to handle, light and handy.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
