Abstract
The utility model discloses a kind of mini-invasive incision cardiac operation under direct vision pulmonary vein to expose cavum pericardiale attractor, including negative tube, negative pressure device joint, negative tube external screw thread, straight suction tube, straight suction tube internal thread, block suction tube, block suction tube internal thread and butterfly shutter, negative pressure device joint is arranged at one end of negative tube, negative tube external screw thread is arranged at the other end of suction tube, one end of straight suction tube sets straight suction tube internal thread, suction tube internal thread is blocked in one end setting for blocking suction tube, and butterfly shutter is arranged on the outer tube wall for blocking suction tube.The utility model is designed by hickey, the conventional straight sucking head of switching and the sucking head with butterfly shutter, when using butterfly shutter sucking head, pulmonary vein exposure can be carried out simultaneously and cavum pericardiale attracts two kinds of operations, it dramatically saves on the operating space in surgical field of view, it is practical and convenient applied to center chest hypomere mini-invasive incision cardiac operation under direct vision, there is the value of popularization and application.
Description
Technical field
It the utility model is related to a kind of medicine equipment, more particularly to a kind of mini-invasive incision cardiac operation under direct vision pulmonary vein is sudden and violent
Reveal cavum pericardiale attractor.
Background technology
Center chest hypomere mini-invasive incision cardiac operation under direct vision have operative indication scope is wide, wound is small, pain is light,
Post-operative recovery is fast, operative incision is short and the hidden advantage such as attractive in appearance, relative to traditional center chest conventional cut heart straight hand
Art, can preferably cardioprotection surgical site infections patient privacy, be particularly advantageous to the postoperative body and mind of congenital heart disease Children heart
Health, avoid the long otch of postoperative chest from causing children to feel oneself inferior, self-closing psychology, postoperative patient/infant is better blended into normally
Life, study and working environment.
External center chest hypomere mini-invasive incision cardiac operation under direct vision otch may be as little to 2.5-5cm at present, and domestic
Due to lacking particular surgical instrument, center chest hypomere mini-invasive incision cardiac operation under direct vision otch typically can only achieve 4.5-
7cm.In openheart surgery, when carrying out RSPV, right inferior pulmonary vein and the exposure of inferior caval vein gap, prior art condition was both
Need attractor to attract cavum pericardiale blood, need apparatus (such as tweezers) to block atrium side wall above pulmonary vein again, to the small otch heart
For the narrow and small surgical field of view of dirty open surgery, operation technique space is had a strong impact on.The utility model medicine equipment：It is minimally invasive small to cut
Mouth cardiac operation under direct vision pulmonary vein exposure cavum pericardiale attractor, pulmonary vein exposure and cavum pericardiale are attracted into two kinds of operating functions involvements
In a kind of apparatus, the operating space in surgical field of view is dramatically saves on, applied to center chest hypomere mini-invasive incision heart
Open surgery, facilitate operation technique, improve operation safety.
Utility model content
The purpose of this utility model is that to solve the above problems and provides a kind of mini-invasive incision heart straight hand
Art pulmonary vein exposes cavum pericardiale attractor.
The utility model is achieved through the following technical solutions above-mentioned purpose：
The utility model includes spiral shell in negative tube, negative pressure device joint, negative tube external screw thread, straight suction tube, straight suction tube
Line, block suction tube, block suction tube internal thread and butterfly shutter, the negative pressure device joint is arranged at the negative tube
One end, the negative tube external screw thread are arranged at the other end of the suction tube, and one end of the straight suction tube sets the straight suction
Skirt internal thread, it is described block suction tube one end set described in block suction tube internal thread, the butterfly shutter is arranged at
On the outer tube wall for blocking suction tube.
Specifically, the lower end of the shutter is butterfly curved-surface structure.
The beneficial effects of the utility model are：
The utility model is a kind of mini-invasive incision cardiac operation under direct vision pulmonary vein exposure cavum pericardiale attractor, with existing skill
Art is compared, and the utility model is designed by hickey, switches conventional straight sucking head and the sucking head with butterfly shutter, when
During using butterfly shutter sucking head, pulmonary vein exposure can be carried out simultaneously and cavum pericardiale attracts two kinds of operations, dramatically saves on
Operating space in surgical field of view, it is practical and convenient applied to center chest hypomere mini-invasive incision cardiac operation under direct vision, have and push away
The value extensively applied.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- negative tubes, 2- negative pressure devices joint, 3- negative tubes external screw thread, the straight suction tubes of 4-, spiral shell in the straight suction tubes of 5-
Line, 6- block suction tube, 7- blocks suction tube internal thread, 8- butterflies shutter, 9- curved-surface structures.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings：
As shown in Figure 1：The utility model includes negative tube 1, negative pressure device joint 2, negative tube external screw thread 3, straight suction tube
4th, straight suction tube internal thread 5, block suction tube 6, block suction tube internal thread 7 and shutter 8, the negative pressure device joint 2 is set
One end of the negative tube 1 is placed in, the negative tube external screw thread 3 is arranged at the other end of the suction tube 1, the straight suction tube
4 one end sets the straight suction tube internal thread 5, and suction tube internal thread is blocked described in one end setting for blocking suction tube 6
7, the butterfly shutter 8 is arranged at described block on the outer tube wall of suction tube 6.
Specifically, the lower end of the butterfly shutter 8 is curved-surface structure 9.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
