Description

A kind of angiocarpy expander

Technical field

The utility model relates to a kind of expander, in particular to a kind of cardiovascular expander.

Background technique

Currently, when carrying out thoracic surgery sometimes painstaking effort enlargement of pipe can be carried out to patient, when current condition majority Mounting bracket or sacculus in patient's angiocarpy, but because painstaking effort pipeline is thinner, when being manually loaded bracket or sacculus just It is relatively difficult, it is time-consuming and laborious, it adds heavily to the difficulty of the work to medical worker, there are also some cardiovascular expansion devices, the existing heart Vessel dilator is due to being that integral type causes the later period that can not clean up in cleaning and sterilization, and expander is usually by hand Three handle, tracheae and guide head structures, as long as but when wherein a structure member damages, will lead to entire expander and lose make With value, result in waste of resources.Therefore, it is proposed that a kind of angiocarpy expander.

Utility model content

The main purpose of the utility model is to provide a kind of cardiovascular expanders, can effectively solve in background technique Problem.

To achieve the above object, the technical solution that the utility model is taken are as follows:

A kind of angiocarpy expander, including hollow tube, handle and guide head, the hollow tube middle part open up two sides up and down There is air bag outlet, the hollow tube right end inner wall offers internal screw thread, and the internal screw thread is located at air bag outlet right, described hollow Two sides level offers limiting slot to the left up and down for pipe left end, and the guide head is positioned horizontally in hollow tube left, the guide head Right end level is fixedly connected with appendix, and the appendix middle part is mounted on air bag in two sides up and down, and the appendix level is passed through It is through in hollow tube, the equal level of upper and lower ends is fixedly connected with limited block on the right side of the guide head, during the handle is positioned horizontally in Blank pipe right, and level is fixedly connected with screwed pipe, the screwed pipe and hollow tube right end inner wall to the left in the middle part of handle left end Internal screw thread engagement, the screwed pipe inner horizontal offer venting cavity, and the appendix right end is plugged in screwed pipe.

Further, air bag described in two groups is aligned in the vertical direction with the outlet of air bag described in two groups.

Further, the limited block and limiting slot grafting.

Further, the appendix right end is connected to venting cavity.

Compared with prior art, the utility model has the following beneficial effects:

1. the cardiovascular expander of the utility model offers air bag outlet by two sides above and below portion in the hollow tube, Two sides are mounted on air bag up and down in the middle part of appendix, convenient for not will cause in blood vessel when the later period, air bag was supported blood vessel The obstruction of blood.

2. the cardiovascular expander of the utility model, due to offering internal screw thread, handle left end in hollow tube right end inner wall Middle part level is fixedly connected with screwed pipe to the left, is plugged in hollow tube by guide head and appendix, and by handle Screwed pipe and appendix carry out grafting, the later period need to carry out hollow tube, guide head and handle remove cleaning when, Neng Gouqing Wash disinfection more thoroughly, while facilitating later period replacement handle or guide head and appendix, reduce use cost, reduce economic damage It loses.

Specific embodiment

To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below In conjunction with specific embodiment, the utility model is further described.

As shown in Figure 1-3, a kind of angiocarpy expander, including hollow tube 1, handle 5 and guide head 9, in the hollow tube 1 Two sides offer air bag outlet 2 up and down in portion, and the 1 right end inner wall of hollow tube offers internal screw thread 3, and the internal screw thread 3 is located at Air bag exports 2 rights, and two sides level offers limiting slot 11 to the left up and down for 1 left end of hollow tube, and the guide head 9 is horizontal Positioned at 1 left of hollow tube, the 9 right end level of guide head is fixedly connected with appendix 8, two sides above and below 8 middle part of appendix It is mounted on air bag 7,8 level of appendix is applied in hollow tube 1, and the 9 right side upper and lower ends of guide head are horizontal solid Surely it is connected with limited block 10, the handle 5 is positioned horizontally in 1 right of hollow tube, and level is fixedly connected to the left in the middle part of 5 left end of handle There is screwed pipe 4, the screwed pipe 4 is engaged with the internal screw thread 3 of 1 right end inner wall of hollow tube, and 4 inner horizontal of screwed pipe offers Venting cavity 6,8 right end of appendix are plugged in screwed pipe 4.

Wherein, air bag 7 described in two groups is aligned in the vertical direction with the outlet of air bag described in two groups 2.

Wherein, the limited block 10 and 11 grafting of limiting slot.

Wherein, 8 right end of appendix is connected to venting cavity 6.

Working principle: in use, hollow tube 1 is inserted into the angiocarpy of patient by guide head 9, by handle 5 Venting cavity 6 heaves the air bag 7 of about 8 two sides of appendix, and air bag 7 exports 2 pairs of angiocarpy by air bag and heaves, blood Liquid remains unchanged can be flowed by the gap of two groups of air bags 7, needed to carry out the appendix 8 on hollow tube 1 and guide head 9 sterilization and disappeared When malicious, handle 5 is first rotated counterclockwise, the screwed pipe 4 of 5 left end of handle is separated with the internal screw thread 3 of 1 right end inner wall of hollow tube, then will Guide head 5 takes out from 1 left end of hollow tube, and structure is simple, easy to operate.
