Abstract

The invention relates to an incision dilator for a single-hole thoracoscope. The dilator comprises a dilator body, a first dilation ring arranged at the upper end of the dilator body and a second dilation ring arranged at the lower end of the dilator body, wherein the dilator body is tubular, a round channel allowing a thoracoscope camera to pass is formed in the inner side wall of the dilator body, a reinforcing layer is arranged on an inner ring of the round channel, and the diameter of the first dilation ring is larger than that of the second dilation ring. The incision dilator for the single-hole thoracoscope is simple in structure, compact in design and convenient to use, the reinforcing layer is arranged on the round channel allowing the thoracoscope camera to pass and can prevent the thoracoscope camera from compressing the dilator body during using, meanwhile, the thoracoscope camera is supported to a certain extent, deformation of the dilator body in an surgery process is avoided, an incision can be effectively prevented from retraction, and a smooth surgery is guaranteed.

Description

Single hole chamber mirror otch retracts dilator

Technical field

The present invention relates to a kind of single hole chamber mirror otch and retract dilator, belong to technical field of medical instruments.

Background technology

Single hole thoracoscopic operation has been applied comparatively general clinically, and single hole thoracoscopic operation refers to the otch only needing a 2 ~ 10cm, and chamber mirror and operating theater instruments are all by same operative incision.Because tissue has the function of automatically shrinking after but thoracic incision completes, along with the prolongation of operating time, otch can form closure state gradually, like this must be difficult with regard to causing to the carrying out of operation, and carry out in process in operation, multiple operating theater instruments need be worked in coordination with and be carried out, pass in and out otch frequently and easily secondary injury is caused to otch, cause otch to infect, not easily heal, affect the recovery of patient.

Summary of the invention

The object of the invention is the problem in order to the otch solved in single hole thoracoscopic operation easily shrinks, apparatus turnover causes infection of incisional wound, provide a kind of structure simple, single hole chamber mirror otch compact to design retracts dilator.

The present invention adopts following technical scheme: a kind of single hole chamber mirror otch retracts dilator, comprise the first tensioner ring of dilator body and the setting of dilator body upper end and the second tensioner ring of dilator body lower end setting, described dilator body in a tubular form, described dilator body medial wall is provided with the circular channel passed through for thoracoscope photographic head, and the inner ring of described circular channel is provided with back-up coat.

Further, the diameter of described first tensioner ring is greater than the diameter of the second tensioner ring.

Further, the thickness of described back-up coat is 1 ~ 5mm.

Further, described back-up coat adopts nylon material to make.

Further, the diameter of described circular channel is 5 ~ 20mm.

Further, the height of described dilator body is 25 ~ 80mm.

Further, the diameter of described first tensioner ring is 25 ~ 100mm, and the diameter of described second tensioner ring is 25 ~ 100mm.

Structure of the present invention is simple, compact to design, easy to use, on the circular channel that thoracoscope photographic head passes through, be provided with back-up coat can prevent thoracoscope photographic head in use to the compressing of dilator body, play thoracoscope photographic head must supporting role simultaneously, prevent dilator body in operation process from deforming, can effectively prevent otch from shrinking, guarantee carrying out smoothly of operation.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is top view of the present invention.

Fig. 3 is side view of the present invention.

Reference numeral: dilator body 1, first tensioner ring 2, second tensioner ring 3, circular channel 4, back-up coat 5.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Figure 1-Figure 3, a kind of single hole chamber mirror otch retracts dilator 1, comprise dilator body 1, and the second tensioner ring 3 of the first tensioner ring 2 of dilator body upper end setting and the setting of dilator body lower end, the height of dilator body 1 is 25 ~ 80mm, the diameter of the first tensioner ring 2 is greater than the diameter of the second tensioner ring 3, the diameter of the first tensioner ring 2 is 25 ~ 100mm, the diameter of the second tensioner ring 3 is 25 ~ 100mm, dilator body 1 in a tubular form, dilator body 1 medial wall is provided with the circular channel 4 passed through for thoracoscope photographic head, the diameter of circular channel 4 is 5 ~ 20mm, the inner ring of circular channel 4 is provided with back-up coat 5, back-up coat 5 adopts nylon material to make, the thickness of back-up coat 5 is 1 ~ 5mm.

Using method: when needs of patients carries out single hole thoracoscopic operation, first otch is carried out in the target location of thoracic wall, then in otch, dilator body 1 is inserted, first tensioner ring 2 of dilator body 1 is placed in outside otch, second tensioner ring 3 is placed in inside otch, circular channel 4 on dilator body 1 medial wall is for the turnover of thoracoscope photographic head, the dilator body 1 of tubulose, for the turnover of operating theater instruments, can prevent thoracoscope photographic head and other operating theater instruments to be in the visual field in same pipeline mutual frictional impact impact operation.
