Description

A kind of can be used for postoperative spacious of oral cavity free flap transplantation and put drainage system

Technical field

This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of can be used for postoperative spacious of oral cavity free flap transplantation and put drainage system.

Background technology

Operation wound chamber drain is surgical operation later important step.Although the classical drainage technology such as rubber drainage strip, General Purpose Rubber pipe, cigarette-type drain extensively uses in surgical operation, but there is the defect such as function singleness, indwelling time short, easy infection, not manageability in it.Through long-term Clinical Exploration, operation wound chamber drainage technology gradually develops Novel drainage articles for use such as deriving bull drainage tube, band puncture needle and the drainage system of seal wire, the drainage tube of band control valve and negative pressure drainage ball, drainage material there has also been qualitative leap simultaneously, the scope of application the most more specialization.

After part Oral maxillofacial operation, drainage system need to be laid in wound chamber, thus avoid because of tissue compression, wound infection and the palindromia etc. caused by hematocele, hydrops.Due to oral cavity routine operation wound, chamber is relatively small, location tables is shallow, and clinician often selects to place drainage strip in wound chamber, and short-term is pulled out.But for bigger operation on oral cavity, its wound chamber often extends to the underlying tissue structures such as oropharynx, the root of the tongue, buccal, paranasal sinus, and especially oral cavity reconstruction with free flap is postoperative, and its drainage effect concerns wound healing, flap laminating and survival.And simple drainage strip is only capable of passive drain, flow out along drainage strip when i.e. drainage-fluid is more, drainage strip poor effect time less；Secondly, drainage strip quality is the softest, is curled in oral cavity so that drainage-fluid deposits in oral cavity, soaks Intraoral incision and flap, increases the possibility that oral cavity infection occurs；Furthermore, drainage strip retention time is short, only 24-48 hour.Drainage tube for Oral maxillofacial operation wound chamber is less clinically, and the drainage tube postoperative in particular for oral cavity reconstruction with free flap has no report.

Summary of the invention

The purpose of this utility model is that providing a kind of can be used for postoperative spacious of oral cavity free flap transplantation and put drainage system, to solve the problems referred to above.

To achieve these goals, the technical solution adopted in the utility model is such that a kind of can be used for postoperative spacious of oral cavity free flap transplantation and putting drainage system, including drainage tube, described drainage tube is rubber hose, a length of 7-10cm of described drainage tube, and external diameter is 0.4-0.7cm, internal diameter is 0.3-0.6cm, on described drainage tube, the position near wherein one end is provided with several side opening, also includes negative pressure device, and described negative pressure device connects a hard joint.

As preferred technical scheme: a length of 8cm of described drainage tube, external diameter is 0.6cm, and internal diameter is 0.5cm.

As preferred technical scheme: described hard joint is glass connector.Select glass connector with low cost and easily sterilize, easy to use.

Compared with prior art, the utility model has the advantage of: use drainage system of the present utility model, the drainage-fluid that oral cavity free flap transplantation is postoperative can be drawn easily, thus avoid because of complication such as tissue compression, wound infection and the palindromias caused by hematocele, hydrops.And this apparatus structure is simple, Tong Bu carries out with mouth care during use, have easy to operate, fixed, difficult drop-off, with low cost, not by advantages such as indwelling time are limited, there is preferable value for clinical application.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model embodiment；

In figure: 1, drainage tube；2, side opening；3, negative pressure device；4, glass connector.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Embodiment 1: see Fig. 1, a kind of can be used for postoperative spacious of oral cavity free flap transplantation and put drainage system, including drainage tube 1, drainage tube 1 is rubber hose, a length of 8cm of drainage tube 1, and external diameter is 0.6cm, internal diameter is 0.5cm, on drainage tube 1, the position near wherein one end is provided with several side opening 2, also includes negative pressure device 3, and negative pressure device 3 connects a glass tubing 4；

Drainage system provided by the utility model, need to dispose in art, and among the wound chamber being i.e. positioned between surgical wound surface and flap when sewing up free skin flap front portion, tip is placed in wound chamber lowest part as far as possible.Leaving and taking certain length along leading to beyond oral cavity outside flap, is advisable with 1cm with outer portion in oral cavity.After treating that free skin flap is sewed up, use little round needle band silk thread to be perpendicular to drainage tube major diameter through drainage tube tube chamber, and is sewed up be fixed on skin and flap to healing up on；

Postoperative drainage liquid can be flowed directly to outside oral cavity with drainage tube 1, when creating chamber minimum point less than drainage tube end, especially performs the operation at the bottom of mouth, uses the negative pressure device 3 being connected to glass connector 4 to carry out being interrupted lower negative pressure and attracts, and suction pressure controls at below 100mmHg.Method is to need to stay certain distance near drainage tube 1 end, centre by glass connector 4, can the hydrops slowly sucking-off in wound chamber be advisable with captivation.Directly drainage tube 1 can not be docked with glass connector 4, it is to avoid vessel pedicle is held by negative pressure, thus affect flap of blood and supply.Depending on the interval time attracted is according to oral secretion and swollen tissue situation, in the most postoperative 3 days, Q1-2h, if the position in Q2-4h. wound chamber is higher than the external end of drainage tube after 3 days, proper extension interval time then attracted, to ensure that wound intracavity is without hydrops, hematocele.Within during skin flap healing the most general postoperative 5-7 days in mouth, drainage tube can be pulled out.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
