Abstract
The utility model discloses a speculum incision leads out expander, including expander body and the circular passageway of setting on expander body inside wall, seted up the spout along the direction of height on the two inside walls that circular passageway is relative, the circular passageway interpolation is equipped with the division board, and the both sides end of division board is equipped with the draw runner, and the draw runner inserts in order to separate circular passageway in the spout. The utility model discloses be equipped with the division board in circular passageway interpolation and separate circular passageway for the binary channels, and the division board can be dismantled, consequently can carry out the change of single double-channel according to chamber mirror user demand in the operation, and the practicality improves greatly.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to expander is led out to chamber mirror incision.
Background
Thoracoscopic surgery has been used comparatively generally clinically, among the thoracoscopic surgery because human tissue has the function of automatic contraction after the chest incision is accomplished, along with operation time's extension, the incision can form closed state gradually, just so lead to the fact certain difficulty for going on of operation, and the incision is led out this difficulty of solution that the expander can be fine, be equipped with circular passageway on the inside wall on the expander is led out to endoscope incision commonly used, this circular passageway is used for the entering of chamber mirror, however, this circular passageway is mostly the single channel, when needs are used two chamber mirrors in the operation, this circular passageway's use then very inconvenient, two chamber mirrors collide at the single channel is easy, the process to the operation is inconvenient, the process of operation has been delayed.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a speculum is led out to chamber mirror incision can solve the problem among the above-mentioned background art.
The utility model discloses a realize through following technical scheme: the utility model provides a speculum is led out to chamber mirror incision, includes the expander body and sets up the circular passageway on expander body inside wall, the spout has been seted up along the direction of height on the two inside walls that circular passageway is relative, circular passageway interpolation is equipped with the division board, the both sides end of division board is equipped with the draw runner, the draw runner inserts in the spout with the separation circular passageway.
The lower end of the chute is closed.
The slide bar and the partition plate are integrally formed.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses be equipped with the division board in circular passageway interpolation and separate circular passageway for the binary channels, and the division board can be dismantled, consequently can carry out the change of single double-channel according to chamber mirror user demand in the operation, and the practicality improves greatly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is an enlarged view at a in fig. 1.
In the drawings: 1. a dilator body; 2. a circular channel; 3. a chute; 4. a partition plate; 5. and (4) a slide bar.
Detailed Description
The endoscope incision retracting dilator as shown in fig. 1 to 2 in the drawings of the specification comprises a dilator body 1 and a circular channel 2 arranged on the inner side wall of the dilator body 1, sliding grooves 3 are formed in two opposite inner side walls of the circular channel 2 along the height direction, a separation plate 4 is inserted into the circular channel 2, sliding strips 5 are arranged at two side ends of the separation plate 4, and the sliding strips 5 are inserted into the sliding grooves 3 to separate the circular channel 2.
The lower extreme of spout 3 seals, plays the spacing of the draw runner 5 that is equipped with to partition plate 4 both sides end, prevents draw runner 5 roll-off spout 3.
The slide bar 5 is integrally formed with the partition plate 4.
The utility model discloses be equipped with the division board in circular passageway interpolation and separate for the binary channels with circular passageway, and in the division board can install into or dismantle out circular passageway, consequently can carry out the change of single double-channel according to chamber mirror user demand in the operation, the practicality improves greatly.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
