Description

The disposable holder that retracts

Technical field

This utility model relates to a kind of surgical operating instrument, specifically a kind of disposable holder that retracts.

Background technology

Cerebral operations, especially compared with the operation of position, deep, its visual area is narrow and small and darker, generally only has patient just can see visual area clearly, and when operation needs assistant to coordinate to retract cerebral tissue, but often because assistant does not see visual area, cause coordinating undesirable.Retract holder, when tumor, intraventricular tumor are excised while removing for intracerebral hematoma or in brain, retract cerebral tissue, expose hematoma or tumor tissues.But the existing holder that retracts mostly is the flexible axle property of controlling oneself and retracts holder, and it is high to operation table requirement in use that this type of retracts holder, installs complicated, time-consuming, expensive price, take up room large, for the simple operation as intracerebral hematoma is removed, patient is often reluctant to apply.In addition, traditional pull device, simple in structure, easily cause secondary damage; There is safety problem in monolever operation, loading and dismounting mechanical arm or neurosurgery guidance system easily cause new wound to brain tissue; There is no scale marker, doctor cannot intuitively precisely judge surgical depth.

Utility model content

The purpose of this utility model is to provide a kind of rational in infrastructure, simple to operate, practical, cheap disposable holder that retracts, this disposable holder that retracts can accurately expose operative site, the operation path and the clear visual field that provide at least one surgical operating instrument to enter cerebral tissue inside; Reduce tissue injury, have more invasive, shorten operating time, the threat of overall reduction postoperative infection, provides help for patient revives as early as possible with rehabilitation.

For achieving the above object, this utility model provides following technical scheme:

The disposable holder that retracts, comprises guide and retractor, and there is a slotted eye one end of described guide, and the other end has Spring lock catch; A fixed handle is established in the retractor porch of described retractor; Described guide is plugged on retractor inside, and locks fixed handle by Spring lock catch

As further program of the utility model: the optional position of the retractor porch of described retractor is also provided with a detachable handle.

As further program of the utility model: with the guide porch coating one circle light-absorption layer of Spring lock catch with one end; The retractor porch of described retractor is also coated with a circle light-absorption layer, and the color of light-absorption layer is for being preferably black, to absorb intense irradiation light.

As further program of the utility model: described guide be shaped as ellipse or circle; The shape of the retractor brain tissue that has been also oval or circular, dispersed, has avoided cerebral tissue to concentrate on the active force that retracts of a direction.

As further program of the utility model: described guide is provided with scale marker; On retractor, be also provided with scale marker, operation precision is very clear.

As further program of the utility model: the angle of described fixed handle and retractor entrance place plane is 0-90 degree.

Compared with prior art, the beneficial effects of the utility model are:

This utility model reduces tissue injury, compares traditional pull device and has more invasive, shortens operating time, and the threat of overall reduction postoperative infection provides help for patient revives as early as possible with rehabilitation, and numerous medical workers accept use.This disposable use retracts holder feature: guide and retractor, consist of, retractor is comprised of double handle, and one of them handle can be dismantled, and can stablize intervention, thereby avoided the accidental movement in operation, the damage meeting that patient's brain is caused is less.Band scale marker, operation precision is very clear.Elliptic design, dispersed brain tissue, has avoided cerebral tissue to concentrate on the active force that retracts of a direction.Unique guide shape, can reach seamless target approach tissue and minimize local pressure.Minimize that brain breaks and tissue injury.And be compatible with most of surgery mechanical arms and neurosurgery guidance system.Transparent material, has improved the visibility of doctor to surrounding tissue.Instrument channel porch painted black, can absorb intense irradiation light, makes that doctor's eyes can be more comfortable in the middle of operation process, there is no sense of discomfort.

The specific embodiment

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is only this utility model part embodiment, rather than whole embodiment.Embodiment based in this utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of this utility model protection.

Refer to Fig. 1～8, in this utility model embodiment, a kind of disposable holder that retracts, comprises guide 1 and retractor 2, and there is a slotted eye 11 one end of described guide 1, and the other end has Spring lock catch 12; Retractor entrance 21 places of described retractor 2 are provided with two handles, and one of them is detachable handle 22, and another is fixed handle 23; Described guide 1 is plugged on retractor 2 inside, and by Spring lock catch 12 locking fixed handles 23.

As further program of the utility model: with the guide entrance 13 places coating one circle light-absorption layer of Spring lock catch 12 with one end, retractor entrance 21 places of described retractor 2 are also coated with a circle light-absorption layer, the color of light-absorption layer is for being preferably black, to absorb intense irradiation light.

As further program of the utility model: described guide 1 be shaped as ellipse or circle, the shape of retractor 2 brain tissue that has been also oval or circular, dispersed, has avoided cerebral tissue to concentrate on the active force that retracts of a direction.
