Abstract
The utility model discloses a retroperitoneal balloon dilator, belonging to medical apparatus. The defects in the prior art are as follows: operation is difficult and a handle is difficult to hold tightly and easy to slip from an inner core, thus delaying operation time, influencing operation effect and bringing pains for patients. In the retroperitoneal balloon dilator, the inner core (4) is internally provided with an air inlet hole cover (6), an inner core air inlet hole (7), a gasket (8), a spring (10) and an inner core air outlet hole (12) sequentially from top to bottom, wherein the position of the inner wall of the inner core (4), corresponding to the gasket (8), is provided with a groove (9); the lower part of the outer wall of the inner core (4) is provided with a convex ring (11); and the tail end of an air tube (13) inserting into a balloon (15) is provided with a through hole (14). The retroperitoneal balloon dilator has the advantages: the handle is firmly connected with the inner core, thus being not easy to fall down; the handle is not easy to slip from the hands of the operating surgeon; and the operation is simple in the operation of the clinicist, and the operation effect is improved.
Description
Technical field
This utility model belongs to a kind of medical apparatus and instruments, is used for expanding the pneumoretroperitoneum space before specifically a kind of pneumoretroperitoneum videoendoscopic surgery, is convenient to the apparatus of operation technique---the pneumoretroperitoneum balloon dilator.
Technical background
Before the surgery pneumoretroperitoneum videoendoscopic surgery, all need to use pneumoretroperitoneum balloon dilator expansion pneumoretroperitoneum space now, so that the carrying out smoothly of operation technique.There is following shortcoming in existing pneumoretroperitoneum balloon dilator in clinical use: 1. handle is an elastomeric material, and smooth surface, volume are little, and the patient is difficult to hold with a firm grip during operation, slip phenomenon from hands often occurs; 2. the inner core chamber in the handle is an elastomeric material, and the syringe nozzle of injecting gas is difficult to insert air inlet, often needs could insert operating difficulties with very big strength; 3. be connected not closely between handle and the inner core, easily cause handle during operation from the inner core slip phenomenon; In case slippage then the dilator that need more renew.Owing to above reason, caused the operator not finish operation smoothly, delayed operating time, influenced surgical effect, brought misery to patient.So invent a kind of hand-held convenience, simple to operate, handle is difficult for slippage, make things convenient for the novel pneumoretroperitoneum balloon dilator of clinicist's operation technique is very necessary.
The utility model content
The purpose of this utility model be for provide a kind of hand-held convenience, simple to operate, handle is difficult for slippage, make things convenient for the pneumoretroperitoneum balloon dilator of operating in clinicist's art.
The purpose of this utility model is achieved in that
A kind of pneumoretroperitoneum balloon dilator is made up of handle, inner core, breather and air bag, is provided with air inlet port lid, inner core air inlet, pad, spring and inner core venthole from top to bottom successively in the inside of inner core; Inwall and the corresponding position of pad at inner core are provided with groove; Bottom at interior outer core is provided with bulge loop; The tail end that breather inserts in the air bag is provided with passage.
Top at handle is provided with handle cavity, is provided with bulge loop on the inner core on the top of inner core, and bulge loop is worked in coordination on handle cavity and the inner core.
Outer wall at handle is provided with salient point.
This utility model pneumoretroperitoneum balloon dilator is made of handle, vent portion and air bag.Vent portion is interior core assembly, and air inlet port lid, inner core air inlet, pad, spring and inner core venthole are arranged from top to bottom successively; Inner core venthole expellant gas enters air bag by breather.
In order to guarantee that handle and inner core are connected firmly, the top of this utility model handle is provided with handle cavity, is provided with bulge loop on the inner core on the top of inner core, and bulge loop is worked in coordination on handle cavity and the inner core, and handle can be from the inner core slippage when having guaranteed operation.Simultaneously be provided with salient point, make operative doctor hand-held convenient, be convenient to operation at the handle outer wall.
Core assembly is that hard material is made in the vent portion; Be convenient to the syringe injecting gas.Breather is made by elastomeric material, is enclosed within the outer wall of inner core.Bottom at interior outer core is provided with bulge loop, and the rubber breather closely is fixed on the inner core.The corresponding position of the inwall of inner core and pad is provided with groove, and pad moves up and down in groove.
During this utility model operation, use the syringe injecting gas.The air inlet port lid is withstood in the outlet of syringe, and pad moves down, the compression spring, and gas enters breather by lacuna and inner core venthole around pad and the spring, and the tail end of breather has passage, and gas enters air bag by passage.Syringe stops to inflate the rear spring resilience, moves on the pad, and sealing inner core air inlet, gas can't leak.
Before the pneumoretroperitoneum videoendoscopic surgery art, get patient's posterior axillary line 12 subcostal incisions, cut skin successively, subcutaneous, abdomen is carried on the back each basic unit, open fascia thoracolumbalis, expose perirenal space after finger is inwardly pushed peritoneum open, the air bag of dilator is inserted in the gap, begin to inject air, the general injection about 800-1000ml, after retention balloon 1-3 minute, plunger is extracted, withstood inner core air inlet port lid with syringe nozzle, gas is emitted in the capsule, extracts air bag simultaneously.
The utility model has the advantages that:
1. simple to operate, greatly facilitate in clinicist's the art and operate, improve surgical effect.
2. handle and inner core are connected firmly, difficult drop-off.
3. hand-held convenient, handle is difficult for slippage from the operative doctor hands.
Description of drawings
Fig. 1 is this utility model structure chart.
The specific embodiment
Below in conjunction with accompanying drawing, this utility model is described further by the specific embodiment.
The pneumoretroperitoneum balloon dilator, handle 1 aluminium alloy is made, and the outer wall of handle 1 is provided with salient point 3, makes things convenient for operative doctor hand-held.The top of handle 1 is provided with handle cavity 2, is provided with bulge loop 5 on the inner core on the top of inner core 4, and bulge loop 5 is worked in coordination on handle cavity 2 and the inner core, has guaranteed that handle 1 and inner core 4 are connected firmly.Inner core 4 is provided with air inlet port lid 6, inner core air inlet 7, pad 8, spring 10 and inner core venthole 12 from top to bottom successively.Inwall and inner core 4 corresponding positions at inner core 4 are provided with groove 9; Pad 8 moves up and down in groove 9, and gas enters and seals freely.Bottom at inner core 4 outer walls is provided with bulge loop 11, and rubber trachea 13 is fixing.Rubber trachea 13 inserts in the air bag 15; The tail end of trachea 13 is provided with passage 14, and air enters air bag 15 by passage 14.
