Description

Disposable adjustable slot protector

Technical field

The application is related to a kind of medicine equipment, in particular it relates to a kind of adjustable slot protector.

Background technology

In surgery abdominal operation, after surgeon cuts corrective surgery position, it is usually because tissue contracts act on, Otch can be in closure state.Past, surgeon can utilize metal tractor or drag hook by otch after patient skin incision Pull open, so as to reach the purpose of exposed surgical field of view, but it is excessively inadequate to tear wound or exposure angle that drawing often occurs Situation.Various Wound protectors are had been developed at present and are applied to clinic, usually two annular ports and sleeve between the two Shape film.At this stage, Wound protector is covered on otch, so as to reach the purpose for opening otch, surgeon can be with The opening of Wound protector imposes operation to patient.However, existing Wound protector internally outward opening can not be adjusted, from And cause outer shroud and insert the caliber size of inner ring to cannot be adjusted, i.e., the visual field, patient's hand can not be exposed according to needed for operation Art position size incision and surgeon's arm thickness carry out appropriate regulation, meanwhile, existing various model Wound protectors Also the phenomenon inserted outside inner ring and rout up otch occurs, so as to increase operation risk, reduce operation operability.

The content of the invention

For overcome the deficiencies in the prior art, the application is intended to provide a kind of new adjustable slot protector, in its opening Bore adjusting means is respectively provided with, inserting inner ring with elastic outer shroud, elasticity respectively is connected, and allows it according to corrective surgery otch Exposure visual field size needed for size, corrective surgery and surgeon's arm thickness carry out size regulation to inner and outer ring, reduce operation Operation operability is improved while risk.The application is disposable adjustable slot protector, and it includes elastic outer shroud, elasticity Insert inner ring, outer shroud bore adjusting means, inner ring bore adjusting means and the tubular film between inner and outer ring（Two layers）；Bullet Property outer shroud be fixed on the outside of tubular film upper end, elasticity inserts inner ring and is fixed on tubular film lower end outside, the regulation of outer shroud bore Device is located on the outside of elastic outer shroud, and inner ring bore adjusting means is located at elasticity and inserted on the outside of inner ring；Inner and outer ring bore adjusting means Inside is equipped with some connecting rods, and connecting rod both ends connect inner and outer ring bore adjusting means and elastic inner and outer ring respectively；Two layers It is provided with some connecting rods between shape film, two layers of tubular film inside and outside the connection of connecting rod both sides, connecting rod both ends connection elasticity is outer Ring inserts inner ring with elasticity, and some connecting rods serve while the elastic outer shroud of connection inserts inner ring with elasticity and increase otch and this Frictional resistance between Wound protector tubular film, reduce elastic inner ring of inserting and skid off the wind of otch with part tubular film Danger.Elasticity insert inner ring can be folded mouth inserted by the otch on stomach wall it is intraperitoneal, it is then automatic to recover circlewise to be stuck in abdomen Interior, the outer ring elasticity of elasticity, which inserts inner ring and along elasticity inserts inner ring direction and overturn, to be reached closest to skin at patient incision State, elastic inner and outer ring is because it has certain rigidity, so otch is pulled out and by sleeve-shaped film by patient incision It is isolated with the external world.The Elastic buckle device quantity of described adjustable slot protector is 8-12, is optimal with 8, and Arranged along Wound protector central axial direction.Wherein the material of buckle adjusting means is medical metal or medical high polymer material Material, in the region of elastic outer shroud and the elastic breach for inserting inner ring and elastic outer shroud.Finger, which presses bayonet socket adjuster, makes card Tongue is stuck in Elastic buckle adjusting means, so as to have the function that regulation and fixed elastic outer shroud and elasticity insert inner ring bore. It is jagged due to being all provided with elastic inner and outer ring, and be elastic opening, relative to astomous normal in currently available technology Advise for Wound protector, the adjustable slot protector inner and outer ring of the application is respectively provided with good toughness, is unlikely to deform and grasps Work is simple, improves the convenience and security of operation.

Embodiment

In surgical operation, this adjustable slot protector is positioned in patient's incision of abdominal wall and opens otch drawing, outside The hand of section doctor is stretched into abdominal cavity of patients by this adjustable slot protector and performed the operation.Referring to accompanying drawing 1-6, the application's can Regulation Wound protector inserts the He of 2 outer shroud bore adjusting means of inner ring, 3 inner ring bore adjusting means 4 including the elastic elasticity of outer shroud 1 Tubular film between inner and outer ring（Two layers）5；The elastic elasticity of outer shroud 1 is inserted between inner ring 2 and connects shape by tubular film 5 Into path.Elastic outer shroud 5 is fixed on the outside of the upper end of tubular film 5, and elasticity inserts inner ring 2 and is fixed on the lower end outside of tubular film 5, Outer shroud bore adjusting means 3 inserts the outside of inner ring 2 positioned at the elastic outside of outer shroud 1, inner ring bore adjusting means 4 positioned at elasticity；It is interior Some connecting rods 6 are equipped with inside outer shroud bore adjusting means 3,4, connecting rod both ends connect inner and outer ring bore adjusting means respectively 3rd, 4 and elastic inner and outer ring 1,2；Some connecting rods 7 are provided between two layers of tubular film 5, two layers inside and outside the connection of the both sides of connecting rod 7 Shape film 5, the both ends of connecting rod 7 connect elastic outer shroud 1 and elasticity and insert inner ring 2, some connecting rods 7 rise the elastic outer shroud 1 of connection with Elasticity inserts the frictional resistance increased while inner ring 2 acts between otch and this Wound protector tubular film, reduces elasticity Insert inner ring 2 and skid off the risk of otch with part tubular film 5.Elasticity, which inserts inner ring 2 and can be folded mouth, passes through cutting on stomach wall Mouth is inserted intraperitoneal, and then automatic to recover circlewise to be stuck in abdomen, elastic outer shroud 1 is inserted in inner ring 2 inserts along elasticity to elasticity The upset of the direction of ring 2 reaches the state closest to skin at patient incision, and elastic outer shroud 1 and elasticity insert inner ring 2 because it has Certain rigidity, so otch is pulled out and is isolated patient incision and the external world by tubular film 5.Adjustable slot The quantity of Elastic buckle adjusting means 8 of protector is 8-12, is optimal with 8, and along Wound protector central axial direction Arrangement.Wherein the material of Elastic buckle adjusting means 8 is medical metal or medical macromolecular materials, positioned at elastic outer shroud 1 and bullet Property is inserted in the region of breach 9,10 of inner ring 2.Finger, which presses bayonet socket adjuster 11,12, makes block tongue 13 be stuck in Elastic buckle regulation In device 8, so as to have the function that regulation and fixed elastic outer shroud 1 and elasticity insert the bore of inner ring 2.Elastic outer shroud buckle regulation It is medical metal or medical macromolecular materials that device 11 and elasticity, which insert the material of inner ring bayonet socket adjuster 12, is adjusted positioned at Elastic buckle The side of device 8.Jagged 9,10 are all provided with due to being inserted in elastic outer shroud and elasticity in inner ring 2, and is elastic opening, relative to For astomous conventional cut protector in currently available technology, the adjustable slot protector inner and outer ring of the application has There is good toughness, be unlikely to deform and simple to operate, improve the convenience and security of operation.
